Description

Multi-foundation-bolt embedded workpiece Technical Field The utility model relates to the technical field of building construction, in particular to a multi-anchor bolt embedded workpiece. Background An anchor bolt is a special bolt for fixing equipment, structures, etc. to a foundation. Typically consisting of a screw, nut and washer. The screw is generally cylindrical, one end of the screw is provided with threads for being matched and fastened with the nut, and the other end of the screw is provided with different shapes and structures so as to adapt to different fixing requirements, such as a bent hook shape, a conical shape and the like. The anchor bolts maintain a fixed position of the device or structure by transferring the weight and external force of the device or structure to the foundation, using the stability of the foundation. During installation, the foundation bolts are buried in the foundation, then the installation holes of the equipment or the structure are aligned with the foundation bolts, and the equipment or the structure and the foundation are tightly connected together by tightening nuts. In the prior art, in the pre-burying process of the foundation bolt of the steel structure, one-time molding is poor, and the situations of the bolt such as east-west skew, position deviation and the like often occur.
