Problems solved by technology

But nowadays, when pre-embedding the anchor bolts, there is no unified, standard and standardized construction method to follow. During the construction process, there are inevitably relatively random construction operations, low construction efficiency, and poor pre-embedded construction accuracy. and other problems, coupled with the large number of anchor bolts that need to be embedded, the construction volume is very large

Abstract

The invention discloses an embedment construction method for foundation bolts used for steel structure building construction. A steel structure skeleton of a constructed steel structure building comprises multiple steel stand columns, each steel stand column is supported on a reinforced concrete foundation, a steel backing plate is fixedly welded to the bottom of each steel stand column, and an embedded bolt set is installed on the steel backing plate; the process of embedded construction of each embedded bolt set includes the steps of 1 surveying and setting-out; 2, mold placing and primary foundation bolt installation; 3, primary leveling; 4, profile steel rod fixing; 5, foundation bolt fixing; 6, mold disassembling; 7, concrete pouring; 8, repeating the steps from 1 to 7 until the embedded construction process of all the embedded bolt set is completed. The embedment construction method is simple in step, reasonable in design and good in use effect, construction is convenient, the embedment construction process of the foundation bolts used for steel structure building construction can be conveniently and fast completed, and embedment accuracy of the foundation bolts can be ensured.

Description

technical field [0001] The invention belongs to the technical field of steel structure building construction, and in particular relates to a construction method for pre-embedding adjustable anchor bolts. Background technique [0002] When constructing a steel structure factory building, the steel structure system and the foundation of the steel structure factory building are usually fixedly connected by pre-embedded anchor bolts. In the steel structure system of the steel structure factory building, each steel column is supported on an independent foundation. The independent foundation is a reinforced concrete foundation. Each steel column and the supported independent foundation are fixed by a pre-embedded bolt group. The pre-embedded bolt The group usually includes four embedded bolts respectively arranged on the four vertices of a rectangle. For steel columns of different sizes, the spacing of the embedded bolts in the embedded bolt group used is different. During the c...
