Prefabricated wallboard of multifunctional green building

Abstract

The invention relates to a prefabricated wallboard of a multifunctional green building. The prefabricated wallboard comprises a reinforced concrete layer positioned at the indoor side, a calcium silicate board layer positioned at the outdoor side, and a polyphenyl granule layer positioned between the reinforced concrete layer and the calcium silicate board layer; reinforcing steel bars are arranged in the reinforced concrete layer; FRP (Fiber Reinforce Plastic) ribs are arranged in the reinforced concrete layer and the polyphenyl granule layer. Compared with the prior art, the prefabricated wallboard has the advantages of being good in heat and sound insulation performances, high in strength, convenient to construct, and recyclable in materials.

Description

technical field [0001] The invention relates to a prefabricated wall panel, in particular to a multifunctional green building prefabricated wall panel. Background technique [0002] At present, there are no similar products in this patent at home and abroad, only the following kinds of building external thermal insulation or internal thermal insulation wall panels, but because they do not comprehensively consider the requirements of building green, there are many defects. [0003] As for the wall panels of the external thermal insulation layer of the building, most of them are externally attached thermal insulation wall panels. After the construction of the outer wall of the building is completed, the thermal insulation layer is hung or attached to the outside of the concrete wall panel to achieve the purpose of thermal insulation. This form of wallboard mainly has the following defects: 1) In terms of thermal insulation performance, the external thermal insulation layer is...

AI Technical Summary

Problems solved by technology

This form of wallboard mainly has the following defects: 1) In terms of thermal insulation performance, due to the long-term exposure of the outer insulation layer to the air outside the building, it is corroded, so that the insulation layer falls off or the insulation performance decreases, resulting in the need for insulation. It is replaced every certain number of years, which is not conducive to the sustainable development of green buildings; 2) In terms of structure, this type of wallboard is separated from the main structure, resulting in a long construction period and a lot of labor and materials; 3) In terms of fire resistance, traditional The fire resistance of the thermal insulation material is very poor, and it is easy to cause a building fire during the construction process, resulting in the loss of life and property; 4) In terms of strength, the strength of the thermal insulation layer is very low, and it has great mechanical defects when applied to the outer wall; 5) In terms of comprehensive performance, there is no unified consideration of other requirements of green buildings, and the function is single

[0004] Another self-insulating assembled wallboard, although it has realized the combination of the wallboard and the insulation layer, it also has the following defects when solving the durability problem of the insulation layer: 1) on the weight of the wallboard, due to the existence of double-layer concrete layers , which increases the weight of the wall panel; 2) In terms of calculation mode, this kind of wall panel is not analyzed according to the composite panel, resulting in a larger wall thickness and increased economic costs; 3) In terms of comprehensive performance, there is no unified consideration of other aspects of green buildings. requirements, single function
