BACKGROUND OF THE INVENTION

[0001] This invention relates to plugs for openings in concrete-block buildings under construction, especially window openings.

[0002] Since recent catastrophic losses from hurricanes to buildings with inadequate structure, building codes in the United States now require closer positioning of frames for window and other openings in concrete-block and other masonry buildings under construction. Although the prior art includes numerous bucks, templates, spacers, plugs and other devices and methods, none exists like the present invention.

SUMMARY OF THE INVENTION

[0004] Objects of patentable novelty and utility taught by this invention are to provide a construction opening plug which:

[0005] can be folded for a non-use mode in which it is easy to store, transport and carry wherever and whenever needed at a construction site;

[0006] can be unfolded quickly and easily for use;

[0007] can be positioned accurately and easily with one hand by a mason or other person;

[0008] can be held in position, leveled and repositioned by the mason or other user while concrete blocks and other masonry is being laid; and

[0009] can be removed easily from the masonry when cementitious material being used without damage to the masonry or to the construction opening plug.

[0010] This invention accomplishes these and other objectives with a construction opening plug having a template panel with a perimeter that has predeterminedly the same shape and size as an outside periphery of a frame that is selected to be positioned in a opening of a masonry building under construction. The template panel has edges on which form panels are positioned pivotally between a use mode with the form panels being predeterminedly orthogonal to the template panel and a non-use mode with the form panels being predeterminedly parallel to the template panel. Positioned and articulated for easy grasping on the template panel is at least one positioning handle that can include hand-grasp apertures proximate a center of the template panel. The form panels include tolerance thicknesses that are predeterminedly equal to prescribed thicknesses of form cement with which the frame is intended to be cemented to an inside periphery of a construction opening and any furring thereof that is formed against outside surfaces of the form panels in the use mode. The construction opening plug is removed from the construction opening and replaced by the frame which then is centered in and cemented to the construction opening when the masonry has hardened appropriately.

The first leg 13 and the second leg 14 have equal orthogonal thicknesses that are predeterminedly proximate regulatory thicknesses of space between inside surfaces of the construction opening 9 and outside surfaces of the window frame 11 for receiving cementitious material 17 with which the window frame 11 is intended to be cemented to the inside periphery of the construction opening 9 and any furring thereof.

[0069] The orthogonal thicknesses of the first leg 13 and the second leg 14 are preferably equal to thicknesses of the top form panel 2, the bottom form panel 3, the first-side form panel 4 and the second-side form panel 5.

[0070] The top form panel 2, the bottom form panel 3, the first-side form panel 4 and the second-side form panel 5 can have form-panel thicknesses that are predeterminedly equal and that are predeterminedly equal to predetermined regulatory thicknesses of space between inside peripheries of construction openings 9 and outside peripheries of window frames 11 for receiving cementitious material 17 with which the window frames 11 are intended to be cemented to the inside peripheries of construction openings 9 and any furring thereof.

[0071] The construction opening plug with the top form panel 2, the bottom form panel 3, the first-side form panel 4 and the second-side form panel 5 affixed orthogonally to the template panel 1 has an external periphery that is congruent to a construction opening 9 and any furring thereof to be formed about the construction opening plug.

[0072] The external periphery of the construction opening plug is congruent to a predetermined window frame 11 and there is a regulatory space for receiving the cementitious material 17 and for assuring structural integrity intermediate the external periphery of the predetermined window frame 11 and an internal periphery of the construction opening 9.

[0073] Referring to FIGS. 7-25, a foldable embodiment, the template panel 1 can include the top form panel 2 attached pivotally to the top edge; the bottom form panel 3 attached pivotally to the bottom edge; the first-side form panel 4 attached pivotally to the first-side edge; and the second-side form panel 5 attached pivotally to the second-side edge. Preferably, the top form panel 2 has a pivot axis that is parallel to the top edge. The bottom form panel 3 has a pivot axis that is parallel to the bottom edge. The first-side form panel 4 has a pivot axis that is parallel to the first-side edge. The second-side form panel 5 has a pivot axis that is parallel to the second-side edge.

[0074] Preferably further for this foldable embodiment, the top form panel 2 is pivotal intermediate a use mode in which the top form panel 2 is predeterminedly orthogonal to the template panel 1 and a non-use mode in which the top form panel 2 is predeterminedly parallel to the template panel 1. The bottom form panel 4 is pivotal intermediate the use mode in which the bottom form panel 3 is predeterminedly orthogonal to the template panel 1 and the non-use mode in which the bottom form panel 3 is predeterminedly parallel to the template panel 1. The first-side form panel 4 is pivotal intermediate the use mode in which the first-side form panel 4 is predeterminedly orthogonal to the template panel 1 and the non-use mode in which the first-side form panel 4 is predeterminedly parallel to the template panel 1. The second-side form panel 5 is pivotal intermediate the use mode in which the second-side form panel 5 is predeterminedly orthogonal to the template panel 1 and the non-use mode in which the second-side form panel 5 is predeterminedly parallel to the template panel 1.

[0075] Also for the foldable embodiment, the top form panel 2 is positioned on the top edge of the template panel 1 in the use mode; the bottom form panel 3 is positioned on the bottom edge of the template panel 1 in the use mode; the first-side form panel 4 is positioned on the first-side edge of the template panel 1 in the use mode; and the second-side form panel 5 is positioned on the second-side edge of the template panel 1 in the use mode.

[0076] Referring to FIGS. 13-15 and 27, horizontal integrity of the foldable embodiment can be aided by at least one top-panel brace 18 that is affixable proximate the top edge for affixing the top form panel 2 predeterminedly orthogonal to the template panel 1; at least one bottom-panel brace 19 that is affixable proximate the bottom edge for affixing the bottom form panel 3 predeterminedly orthogonal to the template panel 1; at least one first-side-panel brace 20 that is affixable proximate the first-side edge for affixing the first-side form panel 4 predeterminedly orthogonal to the template panel 1; and at least one second-side-panel brace 21 that is affixable proximate the second-side edge for affixing the second-side form panel 5 predeterminedly orthogonal to the template panel 1.

[0077] The panel braces 18-21 can be made to pivot in and out of brace apertures 22 in the template panel 1. Pivoted into the brace apertures 22, they are in a non-use mode. Pivoted out of the brace apertures 22, they are in a use mode with top edges supporting the top form panel 2, the bottom form panel 3, the first-side form panel 4 and the second-side form panel 5.

[0078] For affixing the top form panel 2, the bottom form panel 3, the first-side form panel 4 and the second-side form panel 5 pivotally orthogonal to the template panel 1, bolt-hinges 23 shown in FIGS. 7-9, 21-22 and 24-25 or flexible hinges 24 shown in FIGS. 10-15 can be employed. Piano hinges, hook hinges, strap-like hinges, cloth-like hinges and other hinges also can be employed.

[0079] Further, as shown in FIG. 27, the plug may have holding tabs 25 in the sides 4 and 5 which fold-out for placement between concrete blocks in an opening as a wall is being built. The tabs 25 prevent or at least deter the plug from being blown out by high winds.

[0080] A new and useful construction opening plug and method having been described, all such foreseeable modifications, adaptations, substitutions of equivalents, mathematical possibilities of combinations of parts, pluralities of parts, applications and forms thereof as described by the following claims and not precluded by prior art are included in this invention.
