Concrete small-cross section special-shaped column mould box method construction method

Abstract

The invention discloses a concrete small-cross section special-shaped column mould box method construction method. The concrete small-cross section special-shaped column mould box method constructionmethod comprises the following steps: S1, performing deepening design, and determining the types, the numbers and the cross sections of the mould boxes required to be added for changing a special-shaped column into a rectangular column; S2, manufacturing the mould boxes; S3, performing lofting on side lines of a small-cross section concrete special-shaped column and a rectangular contour line; S4,mounting reinforcing steel bars of the small-cross section concrete special-shaped column; S5, mounting mould plates of the small-cross section concrete special-shaped column; and S6, pouring, vibrating, curing, checking and accepting concrete of the small-cross section concrete special-shaped column. According to the construction method, the special-shaped column is changed into the rectangularcolumn through rectangular mould plate boxes, so that the mould supporting reinforcing construction process is simplified; the construction speed is high; the efficiency is high; the safety of a reinforcing system is ensured; the waste caused by cutting a large mould plate into small mould plates and cutting a steel pipe can be avoided; standardized and sized rectangular template boxes can be prefabricated in a factory directly and spliced on site; and the mould plate boxes, and the mould supporting and reinforcing materials can be used repeatedly, so that the construction energy consumption is reduced, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method of using a rectangular template box to assist in pouring concrete small-section special-shaped columns (mold box method). Background technique [0002] In construction engineering, for the construction of concrete small-section special-shaped columns, the traditional reinforcement method is to use steel pipes to reinforce the formwork along the contour of small-section special-shaped columns. The existing problems are: [0003] 1. It is very easy to cause deformation and displacement of the protruding part of the special-shaped column, and the change of the cross-sectional size of the component; [0004] 2. The formwork at the two inner corners of the special-shaped column is easily squeezed and deformed (as shown in the attached figure), resulting in the cross-sectional size, flatness, and verticality of the small-section concrete special-shaped column not...

AI Technical Summary

Problems solved by technology

[0003] 1. It is very easy to cause deformation and displacement of the protruding part of the special-shaped column, and the change of the cross-sectional size of the component;

[0004] 2. The formwork at the two inner corners of the special-shaped column is easily squeezed and deformed (as shown in the attached figure), resulting in the cross-sectional size, flatness, and verticality of the small-section concrete special-shaped column not meeting the specification requirements;

[0005] 3. At the same time, due to the difficulty in strengthening the short side of the special-shaped concrete column with small cross-section, the support is easily deformed or even unstable due to the deformation of the formwork;

[0006] 4. The formwork of the traditional small-section concrete special-shaped column needs to cut a large number of formwork for assembly, and the reinforcement of the small-section concrete special-shaped column needs to cut a large number of short steel pipes to meet the reinforcement of the special-shaped column, resulting in a lot of material waste
