A construction method of combined formwork

Abstract

A construction method of a combined formwork. The combined formwork is used to first pop up the position lines of the wall body, the door opening, and the window opening on the floor, and then set up columns respectively, take a plurality of panels, connect with the columns, and use connecting beams to connect them. Between the adjacent columns, form a whole, then process the panel corresponding to the door opening and the panel corresponding to the window opening, and use the first wooden board, the second wooden board, and the third wooden board to block, so as to obtain the door opening forming mold and the window opening forming mold, and finally , pouring concrete, removing the formwork after forming, and obtaining the wall. The invention can save a large amount of construction period, thereby reducing the construction cost, and can flexibly adjust the formwork according to the construction site to meet the site requirements of the construction unit.

Description

technical field [0001] The invention relates to the field of construction, in particular to a construction method of a combined formwork. Background technique [0002] Building formwork is an important tool in the construction of concrete structures. In cast-in-place concrete structure engineering, formwork engineering generally accounts for 20% to 30% of the cost of concrete structure engineering, 30% to 40% of engineering labor, and about 50% of construction period. The construction method of building formwork directly affects the quality, cost and benefit of engineering construction, so it is an important content to promote the progress of construction technology. [0003] At present, the commonly used formwork systems in engineering projects are mainly divided into traditional formwork systems and aluminum alloy formwork systems. The most commonly used wood formwork system is gradually being eliminated by the market due to shortcomings such as difficulty in guaranteein...

AI Technical Summary

Problems solved by technology

The most commonly used wood formwork system is gradually being eliminated by the market due to its shortcomings such as difficulty in guaranteeing product forming quality, less turnover times, large labor consumption, and a large waste of wood resources; it has high recyclability, high turnover times, and good product forming quality. Aluminum alloy formwork has been widely used in construction due to the advantages of green and environmental protection. However, the aluminum alloy formwork system has a long mold matching period, cannot be modified on site after processing, has poor flexibility, and has disadvantages such as difficult repair after denaturation.
