Modularization formwork for concrete pouring

Abstract

A modularization formwork for concrete pouring comprises first components, a first side end cover, a second side end cover, an upper end cover and a lower end cover. The first components are made of hollow first sectional bars provided with first grooves. An upper groove and a lower groove connected with the corresponding first groove are formed in the upper end and the lower end of each first component respectively. The first side end cover and the second side end cover are made of second sectional bars with cavities, first protruding parts are arranged on the cross section sides of the second sectional bars, second protruding parts and third protruding parts are arranged on the other sides opposite to the cross section sides, the first protruding parts and the second protruding parts are arranged at intervals, and second grooves are formed between the second protruding parts and the third protruding parts. The upper end cover and the lower end cover are formed by cutting the second sectional bars into the preset length, and first protruding parts, second protruding parts, third protruding parts and second grooves are correspondingly arranged. The first grooves, the second grooves, the upper grooves and the lower grooves are roughly the same in shape and size and are suitable for containing the first protruding parts. The modularization formwork can be manufactured into the size conforming to the building standardization and can be repeatedly used hundreds of times, and therefore a large amount of wood can be saved.

Description

technical field [0001] The invention relates to the field of building structural components, and in particular to a modular formwork for pouring concrete. Background technique [0002] According to statistics, the construction industry has become the largest user of wood consumption in my country's industrial sector, accounting for more than 70% of the wood consumption in the industrial sector. For example, in the first half of 2010, the housing construction area of ​​national real estate development enterprises reached 3.084 billion square meters. According to the ratio of construction area to concrete formwork area of ​​10:1, these 3.084 billion square meters of houses need to use 308.4 million square meters of building concrete formwork. If 2 / 3 of these concrete forms are wood concrete forms, then about 3.08 million cubic meters of wood will be consumed (calculated based on the average thickness of the concrete formwork of 15mm). That is to say, in order to manufacture t...

Problems solved by technology

[0003] In addition, although the cost of concrete formwork made of wood is relatively low, such concrete formwork can only be used once or several times, and then it is discarded, thereby generating a large amount of construction waste, and the disposal of these construction waste also requires a certain amount of time. cost
