Wall plate for attaching beams to masonry walls

Abstract

A wall plate for attaching a structural beam to a masonry wall is disclosed. The wall plate has a flat plate having at least two bolt holes and an absence of nail holes therethrough. At least one anchor is fixed to the flat plate and extends from one side of it. Means are welded to that side which have at least two threaded apertures therethrough, where each aperture is aligned with a bolt hole. There is a removable covering over the means. Methods of using the wall plate are also disclosed. To make a precast concrete panel, one or more wall plates are attached by any suitable means to the inside of forms at the positions required to bolt the resulting panel to structural beams and concrete is poured into the forms. After the concrete has set, the precast concrete panel is transported to the building construction site and is positioned so that an angle connector can be bolted to the wall plate and to a structural beam, If the masonry wall is made of laid concrete blocks, concrete is poured into the top of blocks and the wall plate is pressed horizontally into that concrete. Structural beams can then be bolted to the wall plate.
