Abstract

Abstract An earthquake restraint mechanism helps to prevent the collapse of tilt-up style exterior wall panels (7, 64) of a building (17). The panels are coupled to one another at their abutting joints (16) through L-shaped brackets (18, 20, 68) mounted to the wall panels and restrainers (32, 66, 106) connecting the outwardly extending legs (28, 30, 90) of the brackets. The panels are energetically coupled to one another because the brackets act as shock absorbers which absorb the initial shock on the all panels from an earthquake. Because the panels are tied together, the panels are restrained from collapsing thus helping to protect persons and property. An accumulative effect of energy absorption is evident with the redundant use of the restraint mechanism. The panels can also be connected to other structural members, such as joists or beams, as well.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 245 words
An earthquake restraint mechanism, for use with buildings of the type having structural members, the structural members including a plurality of wall panels, the wall panels having first surfaces, second surfaces, side edges and upper edges, the wall panels being mounted with the side edges of wall panels adjacent other wall panels, comprising: a restrainer assembly coupling a first of the wall panels to an adjacent, second wall panel, the restrainer assembly including: a first restrainer mount secured to the first wall panel and a second restrainer mount secured to the second wall panel; a restrainer coupling the first and second restrainer mounts; at least one of the restrainer and restrainer mounts including panel to panel shock absorbing structure; first and second alignment plates positioned against the first and second surfaces of the first and second wall panels, the first and second alignment plates including through holes; fastening elements passing through the through holes in the first and second alignment plates and passing through the first and second wall panels; the first and second restrainer mounts secured to the first alignment plate by the fastening elements, the fastening elements and alignment plates adapted to permit movement of the wall panels in a plane defined by the wall panels but to inhibit other movement of the wall panels; whereby the restrainer assembly helps keep the first wall panel and the second wall panel from falling down after the building has been subjected to an external force.
Claim 2
Dependent Claim 245 words
An earthquake restraint mechanism, for use with buildings of the type having structural members, the structural members including a plurality of wall panels, the wall panels having first surfaces, second surfaces, side edges and upper edges, the wall panels being mounted with the side edges of wall panels adjacent other wall panels, comprising: a restrainer assembly coupling a first of the wall panels to an adjacent, second wall panel, the restrainer assembly including: a first restrainer mount secured to the first wall panel and a second restrainer mount secured to the second wall panel; a restrainer coupling the first and second restrainer mounts; at least one of the restrainer and restrainer mounts including panel to panel shock absorbing structure; first and second alignment plates positioned against the first and second surfaces of the first and second wall panels, the first and second alignment plates including through holes; fastening elements passing through the through holes in the first and second alignment plates and passing through the first and second wall panels; the first and second restrainer mounts secured to the first alignment plate by the fastening elements, the fastening elements and alignment plates adapted to permit movement of the wall panels in a plane defined by the wall panels but to inhibit other movement of the wall panels; whereby the restrainer assembly helps keep the first wall panel and the second wall panel from falling down after the building has been subjected to an external force.
Claim 3
Dependent Claim 26 words
The restraint mechanism of claim 1 further comprising sleeve means, surrounding the fastening elements, for creating bearing surfaces between the fastening elements and the wall panels.
Claim 4
Dependent Claim 17 words
The restraint mechanism of claim 1 wherein the first and second wall panels define a flat plane.
Claim 5
Dependent Claim 28 words
The restraint mechanism of claim 1 wherein the first and second restraint mounts include L-shaped brackets which act as at least a portion of the shock absorbing structure.
Claim 6
Dependent Claim 61 words
The restraint mechanism of claim 4 wherein the first alignment plate has a U-shaped cross-sectional shape with legs facing away from the first surfaces of the first and second wall panels, the L-shaped brackets having legs sized to fit between the legs of the U-shaped brackets from twisting about an axis perpendicular to the first surface of the adjacent wall panel.
Claim 7
Dependent Claim 22 words
The restraint mechanism of claim 1 wherein the through holes in the first and second alignment plates are longitudinally directed elongate slots.
Claim 8
Dependent Claim 176 words
An earthquake restraint mechanism, for use with buildings having tilt-up exterior wall panels mounted about the exterior perimeter of the building, the panels having side edges and top edges, the panels mounted side edge to side edge to define joints therebetween, comprising: brackets, having first members mounted to wall panels on opposite sides of the joints and having second members extending away from said wall panels; bolt means, passing through holes in the wall panels for securing the brackets to the wall panels; sleeve means, surrounding the bolt means, for providing bearing surfaces between the bolt means and the wall panels; means for restricting pivotal movement of the brackets relative to the wall panels; means for connecting the second members of the brackets, located either side of wall joints, to one another; and at least one of the brackets and connecting means including shock absorber means for absorbing an initial seismic energy load on the wall panels so to help keep the adjacent side edges together and to help keep the wall panels from falling down.
Claim 9
Dependent Claim 176 words
