Description:

The invention concerns the field of temporary constructions.

In the context of humanitarian aid and leisure in particular, it is often necessary to arrange constructions for temporary usage to a greater or lesser extent (around a few weeks, a few months or sometimes even a few years) in order to form for example shelters intended to receive washrooms, schools or dwellings.

To this end, it is known to use kits or packages of spare parts comprising in particular insulating panels making it possible to erect such constructions rapidly and easily by assembling the panels.

Document WO 2005/045147 describes a method for fabricating a temporary construction comprising roof panels (referred to as rakes) and facade panels (referred to as longitudinal walls) . The panels are assembled together by flexible membranes extending in line with the panels. These membranes form articulations between the panels and participate in making the construction watertight.

One drawback however of this type of construction is that these connections have a tendency to deteriorate over time. This is because each membrane of a panel is connected to an adjacent panel by a system of Velcro strips (registered trade mark). These strips are fixed to the membrane and panel by adhesive bonding. However, the adhesive is liable to deteriorate under the effect of the climate (ultraviolet radiation, humidity, temperature, etc).

As a result the rigidity and waterproofing of the construction are liable to degrade over time.

One aim of the invention is to propose a temporary construction having improved rigidity and strength over time.

This problem is resolved in the context of the present invention by virtue of a temporary construction comprising a roof panel, a facade panel and a member for fixing the roof panel to the facade panel, the fixing member having an end intended to be fixed to the roof panel and an end intended to be fixed to the facade panel, one of the ends of the member comprising a hook able to cooperate with an orifice provided in one of the panels or in an element fixed to the panel, in order to put the member under tension so as to keep the roof panel in abutment on the facade panel.

The use of fixing members having hooks makes it possible to keep the roof in abutment on the facade and to limit the risks of detachment of the roof.

The construction may also have the following characteristics.

    • the fixing member has a defined length between the ends of the member, the member comprising a means of adjusting the length,
    • the construction comprises a reinforcing or supporting profiled member fixed to the roof panel, the reinforcing profiled member having an orifice intended to receive a hook of the fixing member,
    • the profiled member has a plurality of orifices able to receive the hook,
    • the reinforcing profiled member is able to effect a connection between several roof panels,
    • the roof panel is able to be arched in order to form a curved roof,
    • the construction comprises a tensioning cable able to maintain the arc of the roof,
    • the construction comprises a plurality of roof support profiled members arranged to form a star-shaped frame in which the roof panel comprises a flexible sheet held in shape by the frame,
    • the roof support profiled members are connected together by articulation means allowing their deployment in a star, when the construction is assembled,
    • the construction comprises a reinforcing profiled member fixed to the facade panel, the reinforcing profiled member having an orifice intended to receive a hook of the fixing member,
    • the profiled member has a plurality of orifices able to receive the hook,
    • each end of the fixing member comprises a hook,
    • the hooks lie in the same plane, in opposite directions,
    • the hook has a curved portion extended by a straight end portion,
    • the construction comprises a first facade panel, a first reinforcing panel fixed to the first facade element, a second facade element, a second profiled member fixed to the second facade element, and an element joining the first and second profiled members, each profiled member comprising a rib, the junction element being formed by a profiled member able to grip the ribs in order to assemble the panels together,
    • when the construction is assembled, the facade panels are inclined with respect to the vertical,
    • when the construction is assembled, the fixing members extend outside a sheltered space formed by the temporary construction.

The invention also relates to a method for assembling a temporary construction comprising a roof panel, a facade panel and a member for fixing the roof panel to the facade panel, the fixing member having an end intended to be fixed to the roof panel and an end intended to be fixed to the facade panel, according to which an end of the member comprising a hook in an orifice provided in one of the panels or in an element fixed to the panel, in order to put the member under tension so as to keep the roof panel in abutment on the facade panel.

FIG. 23 is a detailed view of part of the roof of FIG. 21.

In FIG. 1, the temporary construction comprises a floor sheet 10, a facade 100 and a roof 200.

The facade 100 comprises two longitudinal walls 110 and 120 and two end walls 130, 140 intended to be disposed vertically with respect to the ground in order to delimit an internal space, roughly parallelepipedal in shape, of the construction. Each longitudinal wall 110, 120 comprises a plurality of facade panels 111, 121 and reinforcing profiled members 112, 122 extending between the facade panels 111, 121 in order to connect the facade panels together. Likewise, each end wall 130, 140 comprises a plurality of facade panels 131, 141 and reinforcing profiled members 132, 142 extending between the facade panels 131, 141 in order to connect the facade elements together.

The roof 200 is intended to be positioned in abutment on the longitudinal walls 110, 120 in order to cover the internal space of the construction.

The roof 200 comprises a plurality of roof panels 201 and reinforcing profiled members 202, each reinforcing profiled member 202 extending between two adjacent roof panels 201 in order to connect the roof panels 201 together. The reinforcing profiled members 202 extend in a general transverse direction of the roof 200.

The roof panels 201 are arched in order to form a roof 200 having a curved profile. A plurality of tensioning cables 203 maintain the arc of the roof 200.

The construction also comprises a plurality of sheets 113, 123, 133, 143, each sheet 113, 123, 133, 143 being respectively fixed by an edge to the facade panels 111, 121, 131, 141 close to a bottom edge of a longitudinal wall 110, 120 or of an end wall 130, 140. The sheets 113, 123, 133, 143 extend over the floor sheet 10, around the facade. The sheets 113, 123, 133, 143 can be held on the ground by means of ballasts deposited on the sheets 113, 123, 133, 143 or fixing elements (of the peg or reinforcement bar type).

The sheets 113, 123, 133, 143 thus participate both in holding the construction on the ground and the waterproofing of the bottom part of the construction.

The temporary construction also comprises anchoring cords 207 connected to the ground by means of stakes or held by ballasts.

As illustrated in FIGS. 2 and 3, the construction comprises a tensioning cable 203 and fixing members 204 disposed at each end of the tensioning cable 203 in order to fix each end of the tensioning cable 203 to the same reinforcing profiled member 202.

More precisely (as illustrated in FIG. 4), each fixing member 204 has a longitudinal direction and two ends, each end comprising a hook 214, 224. One of the hooks 214 is intended to be fixed to a tensioning cable 203 while the other hook 224 is intended to be fixed to a roof reinforcement profiled member 202. The hook 214 intended to be fixed to the tensioning cable 203 comprises a curved portion while the hook 224 intended to be fixed to a roof reinforcement profiled member 202 comprises a curved portion and a straight end portion extending the curved portion, the straight end portion extending in a direction roughly perpendicular to the longitudinal direction of the fixing member 204. In addition, the hooks extend in the same plane, in opposite directions with respect to the general longitudinal direction of the fixing member 204. The fixing member 204 also comprises means 234 of adjusting the length of the member.

As illustrated in FIG. 3, the reinforcing profiled member 202 comprises orifices 212 able to receive the hooks 224 of the fixing members 204 in order to fix an end of the tensioning cable 203 to the profiled member 202.

The reinforcing profiled member 202 is thus kept curved by the tension in the cable 203. The means 234 of adjusting the length of the members 204 make it possible to adjust the tension of the tensioning cable 203 and to tighten the cable 203 when the latter is slackened. This is because the tensioning cable 203 may have a tendency to slacken during aging of the construction or because of faulty handling.

Because the roof 200 is formed by a plurality of roof panels 201 and each roof panel 201 extends from one longitudinal wall 110 to the other 120, the roof 200 has improved waterproofing. This is because the roof does not have any articulation at its apex and no longitudinal connection of the panels is necessary.

Moreover, the roof 200 is in abutment, close to each of its longitudinal edges, on the facade panels 111 and 121.

As illustrated in FIG. 2, the construction also comprises fixing members 204 for fixing the roof 200 to the longitudinal walls 110, 120, each fixing member 204 extending between a reinforcing profiled member 112, 122 of the facade 100 and a reinforcing profiled member 202 of the roof 200 in order to keep the roof 200 in abutment on the longitudinal walls 110 and 120. The hook 214 is intended to be fixed to a roof reinforcement profiled member 202 while the hook 224 having a straight end portion is intended to be fixed to a facade reinforcement profiled member.

In addition, the construction comprises fixing members 205 for fixing the roof 200 to the end walls 130, 140.

More precisely (as illustrated in FIG. 5), each fixing member 205 has a longitudinal direction and two ends, each end comprising a hook 215, 225. One of the hooks 215 is intended to be fixed to a roof reinforcement profiled member 202 while the other hook 225 is intended to be fixed to a facade reinforcement profiled member 132, 142. The hook 215 intended to fixed to the roof reinforcement profiled member 202 comprises a curved portion while the hook 225 intended to be fixed to a facade reinforcement profiled member 132, 142 comprises a curved portion and a straight end portion extending the curved portion, the straight end portion extending in a direction roughly perpendicular to the longitudinal direction of the fixing member 205. In addition, the hooks extend in orthogonal planes. The fixing member 205 also comprises means 235 of adjusting the length of the member.

The roof 200 is thus kept in abutment on the facade 100 by means of the fixing member 204 and 205. The means 214, 215 of adjusting the length of the fixing members 204, 205 make it possible to adjust the tension of the members 205 and to tighten the members 205 if necessary. The fixing of the roof 200 on the facade 100 by means of the adjustable members 205 makes it possible to adapt the temporary construction to the irregularities of the terrain on which the construction is installed.

Moreover, it will be noted that several orifices can be provided in the roof reinforcement profiled members 202 and in the facade reinforcement profiled members 112, 122 in order to be able to modify the attachment position of the hooks. This characteristic makes it possible to adjust or modify the tension of the fixing members according to the irregularities of the terrain on which the temporary construction is installed or to tighten the fixing members.

FIG. 7 depicts schematically, in section, an insulating panel 111 such as can be used for forming a facade panel. However, the same type of panel is used for forming facade panels 111, 121, 131, 141 or roof panels 201.

The panel 111 is a sandwich panel comprising a core 1111 made from insulating material (for example expanded plastic material) and two facing sheets 1112 and 1113 extending on each side of the core 1111 (for example made from non-expanded plastic material). The panel 111 comprises junction ribs 1114 extending between the facing sheets 1112 and 1113 and holding the facing sheets at a distance from each other and stiffening the panel. In addition, the facing sheets 1112 and 1113 join at each of the longitudinal edges of the panel 111 forming a groove 1115 extending along the edge of the panel. It should be noted that the facing panels, the ribs and the grooves can be formed in a single piece by extruding plastics material, the insulating material then being introduced into the cavities formed between the ribs in order to fill the cavities.

FIG. 7 depicts schematically, in section, a reinforcing profiled member 202 connecting between two adjacent panels in order to form a roof or facade. The reinforcing profiled member 202 can be formed by extruding plastics material. The reinforcing profiled member 202 has a symmetrical cross section. The profiled member 202 comprises two pairs of wings 2021 and 2022, each pair of wings delimiting a groove 2011, 2012 extending between the wings.

As illustrated in FIG. 10, each pair of wings 2021, 2022 is able to grip an edge of a panel 111 when the edge of the panel 111 is introduced into the groove 2011, 2012 formed between the wings 2021, 2022.

The profiled member 202 also comprises ribs 2031 and 2032 extending at the bottom of the grooves 2011, 2012, each rib 2031, 2032 being able to be introduced into a groove 1115 in an edge of a panel 111 when the panel 111 is introduced into the groove 2011, 2012 of the reinforcing profiled member 202.

The cooperation of the ribs 2031, 2032 of the profiled member 202 with the grooves 1115 of the panels makes it possible to hold the panels 111 in the profiled member in order to connect the panels 111 together rigidly. In addition, the pairs of wings 2021, 2022 make it possible to effect a watertight junction between the panels 111.

The reinforcing profiled member 202 thus makes it possible to join two adjacent panels. The reinforcing profiled member 202 affects a rigid watertight junction between the panels.

The profiled member 202 comprises amongst other things a longitudinal rib 2023 extending perpendicular to the wings of the pairs of wings 2021, 2022, the longitudinal rib 2023 comprising a free edge forming a reinforcing bead 2024. The longitudinal rib 2023 is intended in particular to be provided with orifices 212 for attaching fixing members 204, 205 as described previously.

In addition, the reinforcing profiled member also comprises a longitudinal groove 2025 extending on an opposite side to the side having the rib 2024, the groove 2025 being able to receive a stiffening element, such as a rod for example. Thus the reinforcing profiled member 202 makes it possible, where it is used to join two adjacent facade panels, to participate in supporting the construction.

Finally, as illustrated in FIG. 8, the profiled member can be used as a roof edge or facade edge profiled member 202′. In this case a pair of wings 2021 extending on one side of the profiled member and the groove bottom ribs 2031, 2032 are omitted. Edge profiled members 202′ thus formed are used as illustrated in FIG. 3.

An edge profiled member 202′ is fixed along the top longitudinal edge of a longitudinal wall 110, 120. For this purpose, the top free edges of the facade panels are introduced into the groove 2012 formed between the pair of wings 2022 of the profiled member 202′ so that the wings 2022 grip the facade panels 111, 121.

Likewise an edge profiled member 202′ is fixed along the longitudinal edge of the roof 200. For this purpose, the longitudinal free edges of the roof panels 201 are introduced into the groove 2012 formed between the pair of wings 2022 of the profiled member 202′ so that the wings 2022 grip the roof panels 201.

In addition, an edge profiled member 202′ is also fixed along the bottom longitudinal edges of the longitudinal walls 110, 120. The edge profiled members 202′ allow fixing of the sheets 113, 123, 133 and 143 to the facade panels. For this purpose, each sheet 113, 123, 133, 143 has along one edge a bead (or rod) able to be introduced by sliding into the groove 2025 of the edge profiled member 202′.

As illustrated in FIG. 3, the edge profiled member 202′ fixed to the roof 200 comes into abutment on the rib 2023 of the edge profiled member 202′ fixed to the facade 100. In addition, the rib 2023 of the edge profiled member of the roof 200 masks the join between the roof 200 and the facade 100. In particular, the rib 2023 of the edge profiled member of the roof 200 participates in making the join watertight.

In addition, as illustrated in FIG. 9, the profiled members can be used as corner junction profiled members. To this end, a corner element 206 in the form of a profiled member having a C-shaped cross section can be disposed so as to grip the longitudinal ribs 2023 of adjacent profiled members 202″ disposed at a corner of the construction. Such a corner element 206 makes the junction between the panels 111, 141 forming an angle of the facade 100 watertight. This corner element 206 also improves the insulation of the temporary construction.

Steps of assembling the temporary construction will now be described.

According to a first step illustrated in FIG. 11, a sheet is unfolded and disposed on the ground in order to cover an area of the ground on which the temporary construction is to be installed. The sheet is fixed to the ground by means of pegs inserted in orifices provided with eyelets provided for this purpose in the sheet.

According to a second step illustrated in FIG. 12, the roof 200 comprising the roof panels 201 is unfolded.

According to a third step illustrated in FIG. 13, tensioning cables 203 are attached at one of their ends to the roof reinforcement profiled members 202. Each tensioning cable 203 is attached to a reinforcing profiled member 202 by means of a fixing member 204.

According to a fourth step illustrated in FIG. 13, the roof 200 comprising the various roof panels 201 is arched. For this purpose, a first team of operators holds a longitudinal edge of the roof while a second team of operators lifts the other edge in order to curve the reinforcing profiled members 202 and the roof panels 201. The operators in the second team next attach the free ends of the tensioning cables 203 to the reinforcing profiled members 202 by means of fixing members 204 so as to tension the tensioning cables 203 in order to maintain the curvature of the roof 200.

According to a fifth step illustrated in FIG. 15, the facade 100 comprising the longitudinal walls 110, 120 and the end walls 130, 140 is deployed and disposed vertically on the sheet.

According to a sixth step illustrated in FIG. 16, the adjacent panels forming the corners of the facade 100 are assembled by means of corner elements 206.

According to a seventh step illustrated in FIG. 17, the roof 200 is positioned above the facade 100 so as to cover the internal space of the construction. The roof 200 is disposed in abutment against the end walls 130, 140.

According to an eighth step illustrated in FIG. 18, the roof 200 is fixed to the facade 100 by means of fixing members 204 disposed on each longitudinal side of the roof. Each fixing member 204 extends between a reinforcing profiled member 202 for the roof 200 and a reinforcing profiled member 112 or 122 for the corresponding facade 100. The fixing members 204 are tensioned using adjustment means 234.

According to a ninth step illustrated in FIG. 19, the temporary construction is fixed to the ground by means of anchoring cords 207 connected to the ground by means of stakes or held by ballasts 208.

The temporary construction that has just been described allows rigid fixing of the roof 200 on the facade. The use of fixing members having hooks makes it possible to keep the roof in abutment on the facade and to limit the risks of detachment of the roof.

The curved roof 200 limits the risks of infiltration of water into the construction. This is because the roof does not have any articulation at its apex and no longitudinal connection of the panels is necessary.

The curved roof 200 can also have a wide span (greater than a raked roof). This makes it possible to produce temporary constructions having an increased width.

The appearance of the roof is also improved. The curving makes it possible to avoid waves and undulations on the roof panels generated in raked roofs by the use of flexible strips and cords.

Moreover, the system for curving the roof 200 by means of tensioning cables and the system of fixing the roof 200 on the facade 100 by means of members having adjustment means makes it possible to adapt the construction to the irregularities of the site and to slacken or tighten the various systems over time if necessary. The curving and fixing systems thus constitute adjustable systems that can be adjusted according to climatic constraints.

In addition, it is possible to omit a facade end wall so as to form a construction with three walls.

The joining system between adjacent panels allows better thermal insulation than a membrane junction system.

In FIG. 20 the temporary construction comprises a facade 300 and a roof 400.

In this embodiment the facade 300 has a roughly pyramidal shape. The facade 300 comprises a plurality of walls inclined with respect to the vertical. More precisely, the facade 300 comprises seven walls delimiting a base surface on the ground in the form of a heptagon.

The walls of the facade 300 are formed by a plurality of facade panels 301 and reinforcing profiled members 302 extending between the facade panels 301 so as to connect the facade panels to each other.

In addition, the facade walls are connected together at the corners of the pyramid by corner elements 406 (identical to the corner element 206 in FIG. 9).

The roof 400 is intended to be positioned in abutment on the panels 301 in order to cover the internal space of the construction.

The roof 400 comprises a flexible sheet 401 and a frame comprising supporting profiled members 202 (shown in broken lines) able to support the sheet in order to form the roof 400. The flexible sheet 401 matches the shape of the supporting profiled members 202 in order to form a roof in the form of an “umbrella” above the facade 300.

As illustrated in FIG. 20, the construction also comprises members 404 (identical to the member 204 in FIG. 4) in order to fix the roof 400 to the facade 300. Each fixing member 404 extending between a reinforcing profiled member 302 for the facade 300 and a supporting profiled member 402 for the roof 400 in order to hold the roof 400 in abutment on the facade 300. More precisely, the fixing member 404 has a hook fixed to a roof support profiled member 402 and a hook fixed to a facade reinforcement profiled member 302.

The fixing members 400 extend outside the sheltered space formed by the temporary construction.

Some supporting profiled members 402 for the roof 400 are kept curved by a pair of members 404, each member 404 being fixed to one end of the profiled member.

FIG. 21 illustrates a roof 400, before assembly with the facade 300.

The roof 400 comprises the flexible sheet 401 having a roughly circular shape and a frame comprising a plurality of supporting profiled members 402 (shown in broken lines).

The supporting profiled members 402 each extending in a radial direction of the sheet 401 so as to form a star structure. The profiled members 402 are articulated on each other at the centre of the sheet by means of a shaft 422.

As shown in FIG. 22, when the temporary construction is dismantled, the profiled members 402 can be arranged in a storage configuration in which the profiled members extend in a parallel direction and are superimposed so as to form a block of profiled members. When the temporary construction is assembled, the roof frame is deployed by making the profiled members 402 pivot about their shaft 422 in order to form the star-shaped frame.

Next, as shown in FIG. 23, each profiled-member end 402 is inserted in a pocket 411 or recess formed in the sheet 401. Thus the sheet 401 is kept tensioned on the star-shaped frame while the profiled members 402 are kept in their deployed configuration by the sheet.

It should be noted that the profiled members 402 have, close to their ends, orifices 412 intended to receive hooks of the fixing members 404.

It should be noted that the various panels used for producing the temporary constructions that have just been described can be manufactured by extrusion techniques or rotational moulding.

In addition, the rigid profiled members used in these temporary constructions can support various items of equipment such as gutters, awnings or medical equipment.

Provision can be made for adding fixing elements, such as concrete reinforcements or metal tubes, at the corners of the constructions in order to reinforce their structure and limit risks of lifting (in particular relating to the action of the wind on the construction).

Finally, the separation partitions can be provided inside the sheltered space in order to form several rooms.
