A kind of environmental protection, thermal insulation composite masonry wall structure and its construction method

Abstract

The invention discloses an environment-friendly, high-ductility thermal insulation composite masonry wall and a construction method thereof, wherein the composite masonry wall includes PVA fiber concrete porous bricks, a thermal insulation board pasted on the outside of the wall, and an environmental protection panel arranged on the outer side of the thermal insulation board. The high-toughness cement-based material prefabricated board is arranged on the outer surface of the high-toughness cement-based material prefabricated board. It solves the problems of poor weather resistance and durability of external wall insulation materials, complicated construction process, difficult control of wall cracks, poor seismic performance, increased wall thickness, but not obvious improvement in thermal insulation effect, and how to do it at the same time The problem of recycling these solid wastes. The invention can effectively improve the construction progress of the masonry wall structure and increase the bending resistance, shear resistance, corrosion resistance, frost resistance and earthquake resistance of the wall through the application of the PVA fiber concrete porous brick and the environmental protection and high toughness cement-based composite material prefabricated board Performance, and more in line with green sustainable development.

Description

Technical field [0001] The present invention specifically involves environmentally friendly, high-profile insulation combined masonry wall structure and its construction method, belonging to the technical field of building outer envelope structure. Background technique [0002] From ancient times, the masonry wall has always been an important part of our construction industry. However, the masonry structure is bent, low shear strength; ductility; corrosion resistance, refrigeration resistance, resulting in poor seismic performance, after seismic, large quantities of masonry structure, and cannot be repaired. Therefore, the masonry in the seismic will not only increase the number of casualties in the seismic, but also cause a large amount of economic losses. [0003] Furthermore, with the promotion of the green sustainable concept, green buildings are gradually recognized by people. Among them, the exterior wall insulation system is one of them. In winter, the external wall insula...

Problems solved by technology

[0006] The present invention aims at the poor weather resistance and durability of the external wall thermal insulation material proposed in the above background technology, the construction process is complicated, the wall cracks are not easy to control, the seismic performance is poor, and the wall thickness is increased, but the thermal insulation effect is not improved. It is too obvious, and at the same time how to recycle these solid wastes, provide an environmentally friendly, high ductility thermal insulation composite masonry wall structure and its construction method, and replace the original sintered porous bricks with PVA fiber concrete porous bricks For bricks and ordinary concrete porous bricks, the use of environmentally friendly, high-toughness cement-based composite material prefabricated panels to replace the original grid cloth and anti-crack mortar and other construction techniques can effectively improve the construction progress of the masonry wall structure and increase the bending resistance of the wall , anti-shear, anti-corrosion, anti-freeze and anti-seismic performance, and more in line with green sustainable development
