Concrete pouring method of concrete heat insulating curtain wall

Abstract

The invention relates to a building construction method, in particular to a concrete pouring method of a concrete heat insulating curtain wall. The method comprises the following steps that (1) concrete is prepared, specifically, according to the thickness of structural concrete and surface layer concrete, the aggregate particle size of the concrete adopts segmentation continuous grading, the amount of stones with the particle size of 5-10 mm accounts for 15-20% of the total amount of stones, the amount of stones with the particle size of 10-30 mm accounts for 80-85% of the total amount of stones, and the slump of concrete stirring material is 160-180 mm; and (2) concrete is poured, specifically, the prepared concrete is injected into concrete separation equipment through a concrete pump pipe, the concrete separation equipment produces two types of concrete of large and small different particle sizes, the stone concrete of with the particle size of 5-10mm enters a template of one side of the surface layer concrete through a fine aggregate outlet, the stone concrete of the particle size of 10-30mm enters the template of one side of the structural concrete through coarse aggregate outlet, and the height difference of the concrete on the two sides is observed and is not more than 200 mm during pouring. According to the concrete pouring method of concrete heat insulating curtain wall, a set of concrete pouring equipment is adopted, simultaneous casting of two types of concrete in a working face is achieved, and the effect that the concrete strength and the structural size met the design requirements is ensured.

Description

technical field [0001] The invention relates to a building construction method, in particular to a concrete pouring method for a concrete thermal insulation curtain wall, which is suitable for the construction of a cast-in-situ concrete thermal insulation curtain wall. Background technique [0002] At present, building energy-saving projects will be widely used in exterior wall insulation technology, and concrete insulation curtain wall is one of them. It is composed of concrete surface and insulation boards, and does not bear the load and function of the main structure Insulated construction. According to different construction techniques, this type of concrete thermal insulation curtain wall includes cast-in-place concrete thermal insulation curtain wall and post-mounted concrete thermal insulation curtain wall. [0003] see figure 1 , in the figure, this type of concrete thermal insulation curtain wall is usually composed of a concrete structure with a thickness of more...

AI Technical Summary

Problems solved by technology

However, when two kinds of concrete with different particle sizes are poured on the same pouring surface, when the height difference of the concrete on both sides exceeds 200mm, a horizontal thrust will be generated, which will cause the displacement of the insulation board in the middle, so that it does not meet the design requirements

In addition, it is not feasible to use two sets of concrete pouring equipment to pour concrete at the same time on one working face; moreover, to pour concrete with two particle sizes alternately on one working face, and keep the height difference of the concrete on both sides not exceeding 200mm, practical experience shows that it is also very difficult
