Building construction method and concrete panel for use therein

摘要

A pre-fabricated cement or concrete panel and an improved system for building construction using such panels is provided. The concrete panel has a threaded tubular connector (concrete insert) imbedded therein for receipt of a bolt. The tubular connector has a head portion, a spaced flange portion and a tubular bolt receiving body portion for receipt of the securing bolt. The flange is securely attached to the tubular bolt receiving body by any convenient method such as welding or crimping. Reinforcement bars are imbedded in the panels on each side adjacent to the periphery of the panel. The flange is placed at a predetermined position between the head and the open end of the bolt receiving body. The predetermined distance between the flange and the head is dependent on the diameter of the reinforcement bars. The distance is selected to allow receipt of reinforcing bars which are placed around the periphery of the cement panels so that the bars sit on the flange and nest against the bolt body in pressure engagement between the bolt head and the flange.
