FIGS. 8 and 9 are broken away detail transverse cross sectional views representing modified connections effected between rear legs of coping members and rear legs of splice support structure.
Referring now more particularly to FIGS. 1 and 2 herein, a coping structure 10, represented installed upon a wall 16, such as a parapet, includes a plurality of channel-like members 11, which are similar in cross section, each comprising a web 12 which interconnects a front leg 13 and a rear leg 14 of the coping member. Adjacent longitudinal ends of the coping members 11 form transverse seams 15 with one another in the installation, the member webs 12 being disposed covering the top of the wall 16 and the front and rear legs 13 and 14 of the members being located forwardly and rearwardly outside upper side facial areas of the wall 16, respectively. The front and rear legs 13 and 14 of each related coping member 11 introduce upwardly and inwardly open doubled lower end portions 13a and 14a which form downwardly and outwardly directed flanges for the coping member to be engaged in a manner hereinafter to be described.
In the present embodiment and in the several other embodiments chosen to be represented in the accompanying drawings, the coping members referred to are preferably made from aluminum alloy sheet material though of course if desired the coping members may instead be produced from some other sheet material such as galvanized sheet steel or be formed as extrusions or molded products of any suitable composition.
At the transverse seams 15, the coping members 11 are connected with the wall 16 and are spliced. Accordingly, each such connection and splice joint includes splice and support means 19 comprising a splice member 20 and splice support structure 30 which are represented in detail in FIG. 3. The splice support structure 30 comprises a wall saddle member 31 provided with a web 32 and front and rear legs 33 and 34. A raised forward portion 32a of the saddle member web 32 is integral with the upper end of front leg 33 and leads downwardly and rearwardly and is integral with a lower rearward portion 32b of the saddle member web thus to contribute rigidity to the front leg 33 through bracing the same , the lower rearward portion of the latter web being integral with the upper end of rear leg 34. Lower outwardly and downwardly directed flange end portions 33a and 34a of the front and rear legs 33 and 34 are introduced for engaging the front and rear flanges 13a and 14a of the coping members 11 thus to arrest upward and in fact downward movement of the coping members on the wall 16.
A plurality of the splice and support means 19, all of which are similar, are spaced apart from one another longitudinally of the wall 16 so as individually to underlie the adjacent ends of the coping members 11 at the transverse seams 15. In these positions, the wall saddle members 31 have their webs 32 bridging across the top of the wall 16 from front to rear, and the front and rear legs 33 and 34 of the saddle members are respectively outside front and rear upper facial areas of the wall 16, meanwhile having the raised forward portions 32a of the webs 32, and the upper ends of the front legs 33, projecting above the top of the wall, and the lower rearward portion 32b of the webs 32 furthermore resting against the top of the wall. The wall saddle members 31 accordingly positioned are secured to the wall 16 as by headed fasteners 59 introduced through appropriate apertures in the wall saddle member legs and into the wall 16 or the saddle members are secured as by use of a bonding material adhering each saddle member to the wall, this with or without the use of headed fasteners.
Splice member 20 in each of the splice and support means 19 is configurated to nest into the channel of any one or another of the coping members 11 and includes front and rear legs 21 and 22 integral with web 23 which interconnects the upper ends of those legs. As installed in adjacent ends of a pair of coping members 11, web 23 of the splice member overlaps the webs 12 of the pair of coping members at the underneath side of the coping members while leading across the related transverse seam 15, this with also having the front and rear legs 21 and 22 overlap the front and rear legs 13 and 14 of the pair of coping members while extending across the related transverse seam 15. A downwardly and outwardly directed lower end flange 21a of the splice member leg 21 is entrant into the inwardly and upwardly open flanges 13a of the related pair of channel members 11 so as in this manner to have the web 23 lie substantially against the webs 12 of the two channel members at the front. Rear leg 22 of the splice member is a straight leg throughout, and terminates at lower end slightly above the inwardly and upwardly open flanges 14a of the related pair of channel members 11 when the splice member 23 is brought up against the webs 12 of the two channel members at the rear.
In the present embodiment, the splice members 20 and the wall saddle members 31 are made from galvanized sheet steel and by cutting and bending into form, though of course any other suitable material or forming operations may instead be resorted to if desired.
In installing any particular one of the similar splice members 20 across the related seam 15, the splice member legs 21 and 22 advantageously are initially sprung apart so as thereafter upon insertion of the splice member into the channels of the pair of coping members 11 the legs 21 and 22 inherently exert pressure upon the legs 13 and 14 of the two channel members, thus closing against the seam 15 from the inside.
Describing further the similar splice seat structures 30, and by referring to but one such splice seat structure 30, which is thought to suffice, a spring strip 40 of galvanized sheet steel, or of any other suitable resilient material , has a rearwardly directed upper flange 40a and a forwardly directed lower flange 40b leading outwardly from opposite sides of a normally rearwardly inclined intermediate connecting strut 40c of the strip. The spring strip 40 is situated in the margin defined on the lower web portion 32b of the related wall saddle member 31 from the rear leg 34 of the wall saddle member, and the lower flange 40b is spot welded to the lower web portion 32b in order to have the intermediate strut 40c and the upper flange 40a resiliently project from the wall web of saddle member 31. A block of neoprene 41 or of other suitable resilient material, adhered to the lower web portion 32b of the wall saddle member 31, is situated between the forward raised portion 32a of the saddle member web 32 and the spring strip 40 and coextends longitudinally of the wall with the spring strip 40 and the supporting wall saddle member web.
With regard to any particular one of the splice seat structures 30 securely on the wall 16 as hereinbefore described, a pair of the coping members 11 forming a transverse seam 15 at their adjacent longitudinal ends outside the wall saddle member 31 of the splice seat structure 30 have their front leg end flanges 13a engaging the front leg flange end portion 33a of the wall saddle member 31 and accordingly are arrested forwardly in the coping structure 10 against upward movement, while downward movement in order to release the front leg end flanges 13a of the pair of coping members from the front leg flange end portion 33a of the wall saddle member is impeded forwardly in the coping structure 10 by the raised forward web portion 32a of the saddle member web and the resilient block 41. Meanwhile, with the rear leg end flanges 14a of the pair of coping members 11 engaging the rear leg flange end portion 34a of the wall saddle member 31 against upward movement of the two coping members, the splice member web 23 is thrust upwardly against the webs 12 of the two coping members under bias of the spring strip 40 and the resilient block 41. Further, in the present embodiment, it will be understood that the plurality of splice and support means 19 are for the coping members 11 used in the coping structure 10 are proportioned so that when the wall saddle members 31 are properly installed on the wall 16 and the front and rear leg end flanges 13a and 14a are engaged with the corresponding front and rear leg flange end portions 33a and 34a of the wall saddle members 31, the webs 12 of the coping members 11 slope rearwardly and downwardly in the coping structure while the webs 23 of the splice members 20 are supported on bias of the spring strips 40 and the resilient blocks 41 on the wall saddle members 31 up against the coping member webs 12 and across the transverse seams 15. If desired, each seam 15 is sealed off by the addition of a caulking compound or of any other suitable sealant between the related splice member 20 and the corresponding end portions of the coping members 11 in the joint. In certain embodiments still in accordance with the present invention the upper end of the resilient block 41 and the upper flange 40a of the resilient strip 40 may instead be affixed to the web of the splice member 20 thus to have a lower free end of the resilient block and a lower free flange of the strip press upon the saddle member web 32 for biasing the splice member upwardly into contact with the coping members 11 at the seam 15.
As need may be in the present embodiment, support and connection with the wall 16 of any particular one of the coping members 11, intermediately of the opposite longitudinal ends of the coping member, is for example had through use of one or more of the splice and support means 19 hereinbefore described, but installed on the wall and connected with the coping member 11 intermediately of the opposite longitudinal ends of the coping member so as to have the associated splice member 20 removed longitudinally of the coping member from any of the transverse seams 15 and serve merely as an intermediate contact or shim member against the web 12 of the coping member within the coping member channel. One such installation is designated as 19a in FIG. 1 and in transverse cross section is similar to FIG. 2 except for the fact that the installation is removed longitudinally of the coping member 11 from either of the transverse seams 15 at the opposite longitudinal ends of the coping member.
In the FIG. 4 embodiment of the present invention, the coping structure as hereinbefore described is modified to the extent that each of the wall saddle members 31 carries a biasing means which comprises a spring strip 42, such as of galvanized steel sheet, the spring strip furthermore including a base 42a which is spot welded to the lower web portion 32b of the saddle member, a forwardly inclined strut 42b integral with a forward flange 42c leading toward the forward raised portion 32a of the saddle member web, and a rearwardly inclined strut 42d integral with a rearward flange 42e leading rearwardly in the saddle member. The forward and rearward flanges 42c and 42e serve as presser feet in contact with the related splice or contact member 20 for the spring strip 42 to raise the related splice or intermediate contact member 20 into contact with one or more of the coping members 11 depending upon whether the particular saddle member 31 is installed intermediately of the longitudinal ends of one of the coping members 11 or is used for bridging across a transverse seam between two of the coping members 11. In certain embodiments in accordance with the present invention, the spring strips 42 disclosed as the biasing means used in connection with the wall saddle members 31 are supplemented by pairs of blocks 43 and 44 (see FIG. 5) such as of neoprene or of other suitable resilient material. Typically, in this respect, block 43 is securely based upon the lower web portion 32b of the related saddle member 31 so as to be between the forward raised portion 32a of the web 32 and the forward flange 42c of the spring strip 42, and block 44 is securely based upon this same lower web portion 32b and projects into contact with the underneath side of the rearward flange 42e of the spring strip 42. The two blocks 43 and 44 have their upper ends in contact with the web 23 of the related splice or intermediate contact member 20 and are held compressed while the flanges 42c and 42e of the spring strip 42 are also in contact with the web 23 and are held deflected, so as to bias the splice or intermediate contact member 20 upwardly against the web 12 of the coping member or members 11 with which the wall saddle member 31 is associated in the coping structure.
In FIG. 6, the embodiment therein represented introduces a truss detail along with biasing means afforded on the wall saddle members 31. Thus, a spring strip 45 of galvanized sheet steel or of other suitable material includes a pair of bases 45a and 45b which respectively are spaced apart in and forward and rearward bases 45a and 45b are interconnected by an intermediate rearwardly and downwardly sloping top truss component 45c and by oppositely downwardly and outwardly inclined side truss components 45d and 45e respectively leading from the forward end of the top truss component 45c to the rearward end of the forward base 45a and from the rearward end of the top truss component 45c to the forward end of the rearward base 45b, the top truss component 45c serving as a rest for the web of the related splice or intermediate contact member 20 and being directly under the rearwardly and downwardly sloping web 12 of either the pair of coping members 11 or the one of the coping members 11 utilized in connection with the saddle member as hereinbefore described. The biasing means in the spring strip 45 includes a forward strut 45f leading forwardly and upwardly inclined from the forward end of base 45a, and a forward flange 45g integral with the upper end of the strut 45f and projecting over the upper end of the raised forward web portion 32a of the wall saddle member 31, and the biasing means in the spring strip 45 further includes a rearward strut 45h leading rearwardly and upwardly inclined from the rearward end of base 45b, and a rearward flange 45i integral with the upper end of the struts 45h and projecting rearwardly above the lower web portion 32b of the wall saddle member 31. The flanges 45g and 45i prior to being installed in the coping structure are sprung upwardly along with the truts 45f and 45h from the bases 45a and 45b so as to be deflected to the positions indicated in FIG. 6 through being installed in the coping structure and thus to bias the web 23 of the associated splice or intermediate contact member 20 upwardly against the web structure of either the coping member 11 or the pair of coping members 11 involved in the connection.
In a further embodiment, represented in FIG. 7, the coping structure is similar to that of FIGS. 1 to 3, inclusive, but involves the introduction of a network of apertures 32c in the lower web portion 32b of the wall saddle members 31 in order to have a cementing agent introduced between the lower web portion 32b and the top of a wall on which the coping structure is installed ooze through the apertures 32c and thus achieve improved bond. Optionally, of course, headed fasteners 59 may be used with or without the cementing agent for fastening the saddle member to the wall and the same comment applies to the other embodiments disclosed herein. It will also be observed that in the FIG. 7 embodiment a spring strip 40' of the character described with reference to FIGS. 1 to 3 is utilized secured in a rearward position on the lower web portion 32b for biasing the rearward portion of the splice or intermediate contact member web 23 upwardly against the web or webs 12 of the coping member or members 11 in the connection, reliance meanwhile being placed upon the upper end of the raised forward portion 32a of the saddle member 31 for maintaining contiguity of the forward portion of the splice or intermediate contact member web 20 to the web or webs 12 of the coping member or members 11 in the connection.
In certain embodiments in accordance with the present invention, screws are utilized for securing lower end portions of the rear legs of the coping members to lower end portions of the wall saddle members, such as in FIG. 8 wherein each screw 47 has its shank through apertures 48 and 49 respectively in a lower end portion of the coping member rear leg 14' and in a lower end portion of the wall saddle member rear leg 34' and threadedly engaged in the apertures with those portions, or such for example as in FIG. 9 wherein each screw 50 has its shank engaged with the coping member rear leg 14" through an aperture 51 in a lower end portion of the coping member rear leg and its shank latchedly engaging a lower end latch portion 52 of the wall saddle member rear leg 34".
