Bond beam and block joist

Abstract

A building has walls built from blocks with cavities. Roofs and floors are formed from joists extending between walls. Each joist has a vertical plate, an angle piece located on each side of the vertical plate and end plates. The end plates bear on the wall blocks. Pins extend from the end plates into cavities of the wall blocks. Bond beams can be positioned on walls parallel to the joist. Horizontal blocks are laid across the joists to form a roof or floor.

Description

[0001]This application is a continuation-in-part application of application Ser. No. 29 / 442,161, filed Dec. 26, 2012.FIELD OF THE INVENTION[0002]The present invention relates to buildings and structures made from blocks and joists.BACKGROUND OF THE INVENTION[0003]There is a need in the United States of America and abroad for low cost housing. Traditionally, permanent housing is of stick and frame construction involving the use of lumber, such as 2×4's, to make the walls and larger lumber boards for joists and roofing. This type of construction requires a relatively high level of skill in carpentry and also expensive construction materials.[0004]As an alternative to such construction, concrete or cement block construction has been explored. Cement blocks are relatively low cost and can be made in molds. While previous efforts to use cement blocks have made progress, costs could further be reduced, particularly in constructing horizontal structures such as roofs and floors.SUMMARY OF ...

AI Technical Summary

Benefits of technology

The patent describes a building made up of stacked blocks with cavities aligned vertically, and joists that support a horizontal roof or floor. The joists have a vertical plate with an angle piece at each end, which is attached to a vertical wall. The angle pieces extend laterally from the vertical plate and have a width that comprises the thickness of the vertical plate and the lateral extension of the angle piece. Each end has a horizontal end plate that extends longitudinally from the respective end, with at least one pin extending vertically down. The end plates have a width that is wider than the angle piece and the vertical plate, and are located on the walls. The building also has horizontal blocks on top of the joists, forming a top surface. In another aspect, the patent describes the use of an angle piece on both joists to support additional weight. The joists are shaped like a "T" in transverse cross-section. The end plates can be interior or exterior, and are designed to fit into cavities in blocks. The building also has a bond beam along a perpendicular wall. The technical effects of the patent include improved load-bearing capacity, stability, and resistance to seismic and wind loads.
