Abstract
An attachment for attaching a precast concrete wall panel to a building in a manner which permits vertical movement of that wall panel relative to building structural elements. In one embodiment, the attachment includes inserts embedded in the wall panel near the top and bottom edges of the upright wall panel, a tongue element connecting the top inserts to a building beam, or the like, and a clamp attached to the bottom inserts to connect those inserts to a building foundation. The inserts have slots defined therein in which portions of the tongue and clamp are located to permit the wall panel and building to move vertically with respect to each other.
Claims8
An attaching means for attaching wall panels to a building comprising:
- a plurality of first inserts mounted in a wall panel near one end thereof;
- a plurality of second inserts mounted in such wall panel near another end thereof which is remote from said one end;
- said inserts each including elongate chamber defining means defining a first chamber for accommodating concrete, said chamber having open ends so concrete can flow freely therethrough and thereinto for securely mounting said each insert in a wall panel, said chamber defining means including a pair of opposed U-shaped side members each having one leg thereof extending toward the other side member and located to be essentially coplanar with one leg of the other side member and spaced apart therefrom to define said elongate slot between said one legs, and elongate slot defining means on said each insert;
- a partition mounted in each of said inserts and including means for separating said first chambers from said slot and defining a slot chamber which is essentially isolated from said first chamber and which remains essentially free of concrete, said partition being U-shaped and having the legs thereof connected to said side member one legs so that said chamber is defined by said one legs, said partition and portions of said side members;
- a plurality of tongue elements each having tongue slots defined therein near one end thereof, said tongue slots having rounded bottom edges and slidably engaging an elongate slot defining means of one of said first inserts with said tongue one ends being received in one of said first insert slot chambers so that said each tongue is slidably connected to said one insert with the other ends thereof projecting outwardly therefrom, a tongue clamp element on each tongue connecting the other end of said each tongue to a building to connect a panel to such building with the sliding engagement between said each tongue and said first insert allowing relative vertical movement between a building connected panel and the building to which such panel is connected, said tongue clamps including a head for fitting over a beam and locking means attaching each tongue clamp to a tongue;
- a plurality of bottom clamp elements each associated with one of said second inserts and each including a fastening means secured to one of said second inserts, mounting means on a building, said each bottom clamp element fastening means being slidably engaged with said mounting means to connect a panel to a building such that relative movement between a building connected panel and the building to which such panel is connected is permitted.
