Problems solved by technology

For the design of embedded column feet, it is more common to directly anchor the anchor bolts into the pile foundation. However, in the suspended state during the installation of the anchor bolts, the pre-embedded anchor bolts are difficult to locate and fix, and the work efficiency and speed are poor. Slow, uneconomical, etc., there has been no better solution

Embodiment Construction

[0026] The construction process of the suspended installation of structural anchor bolts, the technological process is: anchor bolts, mold making → pile foundation reinforcement installation → anchor bolt positioning → anchor bolt installation and fixing → finished product protection → concrete pouring; the specific operations are as follows :

[0027] The first step is to make anchor bolts and molds: make fixture mold 1 in the processing workshop according to the construction drawings, and accurately mark the position of the axis (center line) and the center line of each row of bolt holes on the mold. The marking lines must be clear and accurate, and the allowable deviation is 1mm , the anchor bolt holes are drilled with a drilling machine; the processed mold must meet the following requirements: smooth surface, no warping deformation; accurate cross-sectional size, and the allowable deviation of the diagonal line is not more than 2mm; the position of the bolt hole strictly me...

Abstract

The invention belongs to a method of building construction, in particular to a suspending installation construction process method of a structural anchor bolt, which constructs according to process flows of the anchor bolt and a mould manufacture, pile foundation rebar installation, anchor bolt location, anchor bolt installation and fixing, end product protection and concrete pouring. The process of the suspending installation construction process method adopts 8# angle iron to manufacture high-precision special whole location and fixing clamps according to the design, holes are arranged on the angle iron according to diameter of the bolt and space in a construction drawing, and the inner diameter of the holes is 1mm larger than the outer diameter of the anchor bolt. A suspending steel girder is arranged, wholly fixed bolt groups are connected by using special clamps through the suspending girder by using the angle iron, plane location of the bolt is achieved by adjusting positions of the suspending girder, and elevation control of the girder elevation is achieved through a base plate. Accurate location of the anchor bolt is finally achieved through location monitoring and adjustment of the concrete before concreting, in a concreting process and after concreting. The suspending installation construction process method of the structural anchor bolt has fast installation speed, high installation quality, accurate position, less required equipment, simple operation process and the like.

Description

technical field [0001] The invention belongs to building construction method . Background technique [0002] With the development of my country's national economy, steel structure engineering is becoming more and more favored by construction units. Pre-embedded anchor bolts for various foundations are widely used. The construction accuracy of anchor bolts is very important to affect the quality of steel structure installation. factor. For the design of embedded column feet, it is more common to directly anchor the anchor bolts into the pile foundation, but in the suspended state during the installation of the anchor bolts, the pre-embedded anchor bolts are difficult to locate and fix, and the work efficiency is poor. Slow, uneconomical and other situations, there has been no better solution. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies and provide a construction method for the suspended installati...
