Pre-embedding and fixing method for foundation bolt with diameter of 48mm

Abstract

The invention relates to an pre-embedding and fixing method for a foundation bolt with a diameter of 48mm. the pre-embedding and fixing method comprises the steps of: 1, making a foundation bed on a soil layer with an pre-embedding position of the foundation bolt; 2, assembling a casting mold with a concrete foundation on the foundation bed; 3, symmetrically mounting stabilizing bars on the soil layer on two sides of the foundation bed with the pre-embedding position of the foundation bolt in an inserting manner; 4, symmetrically and fixedly mounting bearing columns on the foundation bed on the outer side of the casting mold with the concrete foundation corresponding to the pre-embedding position, wherein the bearing columns are fixed with aslant stay bars, at the same side with the bearing columns, fixedly mounted on the stabilizing bar; 5, fixedly mounting a bearing crossbar between the symmetric bearing columns; 6, finding the pre-embedding position of the foundation bolt on the bearing cross bar, and pre-embedding and fixing the foundation bolt accurately. According to the pre-embedding and fixing method for the foundation bolt with the diameter of 48mm, a common fastener type steel tube scaffolding is used as the material of a foundation bolt fixed mount, so that mounting is simple and rapid, operation is convenient, and time and labor are saved; the foundation bolt fixed mount is arranged outside the base so as to be capable of being used repeatedly, and thus the usage amount of steel is saved, and construction cost is reduced.

Description

Technical field [0001] The invention belongs to the field of building construction, in particular to a method for pre-buried fixing of anchor bolts with a diameter of 48 mm. Background technique [0002] In the field of construction, the main part of the ground of large stadiums or industrial plants is usually designed as a steel structure. The connection between the column foot or support of the steel structure and the foundation through anchor bolts is a method often used. The diameter is φ48mm bolt is one of the common anchor bolt specifications. Due to the large diameter of this kind of bolts, the pre-buried fixing of the bolts is a key construction procedure before the foundation concrete is poured. In the previous construction, the bolts were pre-embedded with a steel bolt fixing frame. First, the iron parts were embedded on the foundation cushion, the iron parts were welded to the columns, and the diagonal supports were installed between the columns. The beams were instal...

AI Technical Summary

Problems solved by technology

In this method, most of the bolt fixing frames are buried in the foundation concrete at one time, and cannot be reused, resulting in waste of materials

And the construction is relatively complicated, time-consuming and labor-intensive, which increases the construction cost and reduces the production efficiency
