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...

The invention relates to a prefabricated wallboard structure and an assembled building. The prefabricated wallboard structure is characterized in that female rabbets of the wallboards are swallow-tail-shaped grooves; and the two sides of a bridging piece are symmetrically provided with dovetail-shaped tenons which are matched with the female rabbets in a matched and complementary inserting and pulling mode, the bridging piece is provided with a guiding paraffin layer wrapping the surface and a vacuum cavity located in the center, the vacuum cavity communicates with a negative pressure channel, an outer port of the negative pressure channel is blocked by the guiding paraffin layer, and the negative pressure channel communicated with the outside of the bridging piece after paraffin is molten. According to the prefabricated wallboard structure, the paraffin is used as the outer coating layer of the bridging piece, a tongue-and-groove connecting piece made of a metal material is replaced by the self-lubricating property of the paraffin, and meanwhile, in order to avoid the problem of expansion of a butt joint gap caused by melting of the paraffin, the vacuum cavity is additionally arranged in the bridging piece, so that after the paraffin is molten, the butt joint gap is closed through the negative pressure adsorption effect, and the cold bridge breaking effect is further enhanced.
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...
