Method for casting in-situ composite lightweight wall by detaching-free template and equipment thereof

Abstract

The invention relates to a method for casting in-situ composite lightweight wall by a detaching-free template and equipment thereof, comprising: in position of lightweight wall installation at construction site, using pressure fibre cement boards as a external layer of wall and a detaching-free template, casting physical foaming concrete in a sandwich layer between the pressure fibre cement boards. After casting, the physical foaming concrete and the pressure fibre cement board become one to compose the lightweight wall, the circumference of the lightweight wall is cast for one with the construction structure. The wall external layer the composite lightweight wall obtained has high intensity, and interior has low volume weight, reaching excellent performance of lightweight, heat preservation, noise insulation and non-cracking. Besides, a special shunt buffer is collocated, a foaming, mixing and conveying integration foaming conveyor is employed as a filling machine, in-situ highly effective mechanization linkage automatization cast is implemented.

Description

technical field [0001] The invention relates to an on-site manufacturing method and equipment for non-load-bearing walls used in buildings. It is especially suitable for non-load-bearing walls of frame structure buildings, external walls of frame structure buildings that can replace benzene board insulation, and can also be widely used in partition walls and partition walls of residential buildings. Background technique [0002] Because traditional clay bricks occupy a large amount of cultivated land, in order to protect the cultivated land, China banned the production and use of solid clay bricks in 2002, and substitute products for clay bricks emerged as the times require, especially in terms of non-bearing walls, the substitute products are relatively mature, such as A large number of applications of aerated blocks and lightweight strip partition boards, etc., but the above two products have a common feature, both are prefabricated products, that is, they need to be prefa...

Problems solved by technology

[0002] Because traditional clay bricks occupy a large amount of cultivated land, in order to protect the cultivated land, China banned the production and use of solid clay bricks in 2002, and substitute products for clay bricks emerged as the times require, especially in terms of non-bearing walls, the substitute products are relatively mature, such as A large number of applications of aerated blocks and lightweight strip partition boards, etc., but the above two products have a common feature, both are prefabricated products, that is, they need to be prefabricated in a factory to a certain specification and then transported to the construction site, and manual labor is required. Masonry, so it is difficult to achieve high-efficiency mechanized masonry, and the overall cost is high. In addition, the problem of freezing and thawing of aerated blocks has not been solved, which greatly limits the scope of use of aerated blocks. At present, the outer walls of buildings in cold northern regions There are almost no direct use of aerated blocks, as a representative of partition panels: lightweight strip partition panels have been plagued by two obvious defects since the day they were born, no sound insulation and cracked seams, and they have not been completed until now The sound insulation of most light-weight strip panels cannot meet the national requirements, and the cracking of seams often occurs in construction

Another reason is that there is no cast-in-place machinery and feasible methods for forming

The third aspect is economic feasibility, that is, the pouring cost is not competitive with traditional walls
