Enclosing wall stand column construction method

Abstract

The invention discloses an enclosing wall stand column construction method. The enclosing wall stand column construction method comprises the following steps: a of downwards deeply excavating foundation pits at a depth exceeding 800 cm along a design position of a stand column; b of pouring the foundation after the foundation pit are excavated, pre-embedding two vertical rows of reinforcing steelbars in the foundation, and upwards forming a reinforcing steel bar net rack; c, enclosing four panels at the outer side of the reinforcing steel bar net rack and leveling to define a stand column section below the stand column, placing an inner barrel body into the stand column section, and repeating the step until needed enclosing wall stand column height; and f of pouring a concrete structure,and covering a top cover before concrete is solidified, thereby accomplishing enclosing wall stand column construction. The method has the advantages of being convenient in construction, being capableof reducing a construction excavation soil size, improving construction efficiency, being good in construction quality, being high in enclosing wall stand column outline precision, being good in environment friendliness, and the like.

Description

technical field [0001] The invention belongs to the field of fence building structures, and in particular relates to a construction method for fence columns. Background technique [0002] In architecture, a fence refers to a heavy vertical space partition structure, which is used to enclose, divide or protect a certain area, and generally surrounds the walls of buildings. The fence is generally composed of columns arranged at vertical intervals, and walls or railings connected between the columns. [0003] The structure of the existing wall columns generally includes a vertical rectangular parallelepiped column body. The upper end of the column body is provided with a roof protruding from all sides. The column body is generally built of wall bricks and tiles or profiles are pasted on the outer surface. get. This fence column has defects such as long construction time and high cost. [0004] In order to solve the above defects, the applicant has applied for patent CN201821...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned patent still has the following defects: 1. The length of the column panel is prefabricated according to the height of the wall. It seems that only four column panels are needed to form a column to improve the efficiency, but in fact the column panel is a cement prefabricated part. Its dimensional accuracy cannot be guaranteed, so that when the columns are erected, the upper and lower edges of the columns are often misaligned, making it difficult to achieve precise alignment and closing, requiring on-site grinding and secondary processing, which reduces the construction efficiency. As a result, the construction quality and the accuracy of the fence columns cannot be guaranteed

This connection method also has the characteristics of high precision requirements, but the pre-embedded metal parts are usually not too high precision, so it is often impossible to realize the precise connection of the column panel because the precision of the connection parts cannot meet the requirements. Affected the construction progress and reduced the construction quality

3. The existing column foundation construction usually adopts a structure in which the lower end of the foundation is expanded outwards and excavated in a ladder shape and then poured. In this way, the earthwork area required for construction is large and the construction efficiency is low

4. The construction of existing fence columns will result in a lot of construction waste that cannot be processed, resulting in the accumulation of construction waste, affecting the environment, and poor environmental protection performance

In this patent, the hollow multi-segment column shells are spliced ​​along the height direction to obtain the wall column structure, but the specific structure and construction method of each column shell is not disclosed. When the upper and lower shells are docked, it is still difficult to achieve high Efficient and accurate construction
