Detachable building outer wall integrated device

Abstract

The invention provides a detachable building outer wall integrated device which is formed by assembling a plurality of functional modules. Each functional module is provided with a plurality of functional units, and a sliding groove and a convex block which are matched with each other are arranged between any two adjacent functional units in each functional module, wherein the sliding groove is formed in the side surface of one functional unit of the two adjacent functional units, the convex block is arranged on the side surface of the other functional unit of the two adjacent functional units, and the sliding groove and the convex block are oppositely arranged. According to the scheme, an integrated structure is adopted, and construction is quite convenient since complex pasting is not needed for the integrated and years of experience is adopted, and the integrated modules are convenient to assemble, only one module needs to be taken out to be replaced when the modules need to be maintained, the construction and the maintenance time are greatly shortened, and the labor cost and the material cost are saved.

Description

technical field [0001] The invention relates to the field of building exterior walls, in particular to a detachable integrated device for building exterior walls. Background technique [0002] With the progress of the society, people think more about the interdependence between the quality of life and the living environment, and saving energy is the basic national policy of our country. Energy saving, environmental protection, green buildings and materials are the requirements of the living environment, and it is also the embodiment of the value of human scientific research achievements. [0003] In recent years, my country's construction industry has developed rapidly, with an annual increase of nearly 2 billion square meters of construction area. The construction industry has higher and higher requirements for building exterior wall insulation and decoration. At present, my country's building energy consumption accounts for 30% of the total energy consumption, and it is e...

AI Technical Summary

Problems solved by technology

[0008] The main problem that above way exists: 1) thermal efficiency is lower

2) Internal insulation occupies indoor space, reducing the use area

3) The insulation layer is indoors, which brings troubles to the secondary decoration and the addition of hanging facilities, and has a great impact on the residents during maintenance

Existing problems: 1) Currently layered construction, complex process, large amount of wet work

2) The uniformity of the thickness of the plastering mortar is not easy to control, generally 3-4mm, if it is too thick, the resulting dry shrinkage stress is large and it is easy to crack

3) It is not easy to maintain on site, and it is easy to shrink and crack

Existing problems: 1) Due to the decorative stacking and external hanging, the facade effect is not rich, and the use is limited

2) The extruded board and decorative board are fixed by layered expansion nails, and there are many expansion nails passing through the insulation layer, which affects the insulation effect

3) It is more troublesome to deal with corners, waistlines, window covers and protruding parts

Problems: 1) Special equipment is required for on-site spraying

2) The flatness is not easy to control, and it needs to be leveled with thermal insulation glue

3) The source of raw materials is limited and the cost is high

[0014] Combining the advantages and disadvantages of the current common practice, the construction method of the thermal insulation wall commonly used at present is to paste the thermal insulation board at the same time as pouring the outer wall, and then plaster the mortar layer and other materials on the outer surface of the thermal insulation board. This kind of thermal insulation wall exists The problem is that the process is complicated, the workload is large, and it is easily affected by the construction environment and climate, which makes it difficult to control the uniformity of the plastering mortar, and it is easy to crack and other quality defects

In addition, the external wall integrated device in the prior art cannot be disassembled. Once it needs to be replaced, it must be completely replaced. Relatively speaking, the cost of repair and maintenance is very high
