Problems solved by technology

However, the tongue-and-groove connector made of metal forms a cold bridge connecting the indoor and outdoor between two adjacent wall panels, which is not conducive to the indoor thermal insulation effect. Guided, but also able to break the wall panel structure of the cold bridge

Embodiment Construction

[0027] see Figure 1 to Figure 4 As shown, a schematic diagram of the structure of the prefabricated wall panel used in the assembly building in this embodiment is shown. The assembled building is composed of roof panels, upper ring beams, walls, lower ring beams and foundations sequentially connected from top to bottom. The prefabricated wall panel structure between two adjacent wall panels. The detailed structure of the prefabricated wall panel structure will be introduced one by one in conjunction with the accompanying drawings.

[0028] Restricted by the properties of the prefabricated building itself, the prefabricated wall panel structure is a modular assembly structure of components. From the perspective of components, the prefabricated wall panel structure is mainly composed of wall panels 1 and bridges 2 .

[0029] The wallboard 1 is made of a composite board, including a core layer 3 made of polyurethane and a panel 4 made of aerated concrete or calcium carbonate b...

Abstract

The invention relates to a prefabricated wallboard structure and an assembled building. The female rebate of the wallboard is a dovetail-shaped groove; the two sides of the bridge are symmetrically provided with a dovetail-shaped tenon for complementary plugging and matching with the female rebate, and the bridge is provided with a guide covering the surface The paraffin layer and the vacuum chamber located at the center, the vacuum chamber communicates with a negative pressure channel whose outer port is blocked by the guiding paraffin layer and communicates with the outside of the bridge after the paraffin is melted. In the present invention, paraffin is used as the outer covering layer of the bridge, and the self-lubricating property of paraffin is used to replace the tongue-and-groove connector made of metal. At the same time, in order to avoid the problem of expanding the butt joint gap caused by the melting of paraffin, a vacuum cavity is added in the bridge. After the paraffin is melted, the butt joint gap is closed through negative pressure adsorption, further enhancing the effect of breaking the cold bridge.

Description

technical field [0001] The invention belongs to the field of energy-saving building materials, and in particular relates to a prefabricated wallboard structure and an assembled building. Background technique [0002] At present, the wall panels of the prefabricated building are butted by adopting a dovetail or T-shaped mortise and tenon structure, so as to save the screw fastening after the butt joint. In the existing mortise and tenon structure, in order to facilitate the docking between adjacent wall panels, the butt joint surfaces of the wall panels will be embedded with stainless steel or aluminum alloy tongue-and-groove connectors, such as the composite panels disclosed in the prior patent CN101942882A and the use of The wall panel of the composite board provides a good guiding and anti-blocking effect between the two wall panels through the self-lubricating property of the surface of the tongue-and-groove connector made of metal. However, the tongue-and-groove connect...
