Embodiment 1

[0054] 1. Construction preparations

[0055] (1) Familiar with the design content of the drawings, master the design technical parameters and construction requirements of the structural columns of the infill wall, and prepare a special construction plan. The construction plan should go through the relevant approval procedures before organizing construction.

[0056] (2) According to the technical parameters of the components in the main structure, calculate the specifications and dimensions of the pre-embedded steel pipes in the pouring and vibrating holes, and purchase, process and produce in advance.

[0057] (3) According to the drawings, design the strength grade and specifications of the longitudinally stressed steel bars of the structural column, purchase or manufacture the pre-embedded connecting sleeve 1 and the end wire column processing of the stressed steel bar 2, such as figure 1 shown.

[0058] (4) The main materials should be organized to enter the site in adva...

Abstract

The invention relates to a construction method, in particular to an infilled wall constructional column construction method, and belongs to the building field. The infilled wall constructional column construction method comprises the steps of construction preparation, measurement and positioning layout, reinforced connecting sleeve model selection and installation, pouring vibration hole pre-buried steel pipe manufacturing and installation, root rebar pre-burying and fixation, rebar connection and binding, template manufacturing and installation, concrete pouring and construction joint retention, and secondary pouring of expansive concrete. Constructional column longitudinal carrying bars are connected with a main structure, and due to the adoption of the rebar mechanical splicing technology, working efficiency is improved by five times and construction cost is reduced by 30 percent. A constructional column template is fixed through a split bolt, a fixing point is arranged inside a constructional column, reservation of holes in a wall is avoided, and damage to an infilled wall during template fixation is reduced.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method of a filling wall structural column, which belongs to the construction field. Background technique [0002] The structural column of the infill wall is one of the important structural measures used to strengthen the connection between the wall and the main concrete structure and improve the seismic capacity of the wall. The construction of the structural column of the filled wall is carried out after the construction of the main concrete structure and the masonry structure of the filled wall. Common quality problems such as holes and honeycombs, large gaps at the connection between the concrete on the top of the column and the concrete of the main structure due to insufficient filling due to difficulty in tamping, seriously weaken the connection strength and earthquake resistance of the infill wall and the main structure. Contents of the invention [0003] The inv...
