Precast sandwich external wall panel and structural system thereof as well as construction method

Abstract

The invention discloses a precast sandwich external wall panel and a structural system thereof as well as a construction method. The precast sandwich external wall panel comprises an outer shale plate, a thermal insulation layer and an inner shale plate, wherein the thermal insulation layer is arranged between the outer shale plate and the inner shale plate; in addition, the thermal insulation layer penetrates through the precast sandwich external wall panel; the outer shale plate, the inner shale plate and the thermal insulation layer are connected by anchored connecting members. The precastsandwich external wall panel and the structural system thereof provided by the invention have the characteristics of simple structure, convenience in mounting and high structural strength; by using the construction method provided by the invention, an external wall board can be quickly and conveniently mounted to be in place; besides, the construction method has the advantages of high mounting strength, accurate mounting and positioning and low possibility of deviation.

Description

technical field [0001] The invention belongs to the field of building construction and assembly, and in particular relates to a prefabricated sandwich external wall panel, its structural system and construction method. Background technique [0002] In the construction of prefabricated buildings, prefabricated components generally adopt the process of factory prefabricated on-site assembly. The main prefabricated components mainly include external wall panels, laminated beams and laminated floors, etc. The installation method and the structural design of the components directly affect the quality of the entire building. Structural strength and thermal insulation performance, however, the current external wall panel structure system and its construction method still have the following deficiencies: 1. The insulation layer of the existing prefabricated sandwich external wall panel does not run through the entire wall panel, and there is a concrete partition part, and the thermal...

Problems solved by technology

[0002] In the construction of prefabricated buildings, prefabricated components generally adopt the process of factory prefabricated on-site assembly. The main prefabricated components mainly include external wall panels, laminated beams and laminated floors, etc. The installation method and the structural design of the components directly affect the quality of the entire building. Structural strength and thermal insulation performance, however, the current external wall panel structure system and its construction method still have the following deficiencies: 1. The insulation layer of the existing prefabricated sandwich external wall panel does not run through the entire wall panel, and there is a concrete partition part, and the thermal insulation effect is insufficient. ;2. When the floor is cast-in-place, the concrete overflow will cause the section of the external wall panel to be uneven, which is not conducive to waterproofing; 3. Since the external wall panel is flush with the floor panel, when the floor is cast-in-place, it is inevitable that some concrete will flow to the external wall panel 4. When pouring concrete, after the concrete flowing to the section of the external wall panel solidifies, it will make the originally flat section of the external wall panel produce excess thickness, and the cumulative assembly of multi-layer external wall panels After that, there will be a certain difference between the total height of the external wall panels and the floor height
