Description

Technical Field

[0001] The present invention relates to the technical field of wall panel structures, and particularly relates to an adjustable wall panel for prefabricated buildings and an installation method thereof. Background Art

[0002] Prefabricated wall panels are building components prefabricated in a factory and then transported to the construction site for assembly. This building method has gradually gained favor due to its advantages such as high efficiency, environmental friendliness, and controllable quality. Existing prefabricated wall panels are generally of concrete structure. Wall panels of concrete structure are relatively heavy, which is not conducive to the transportation of wall panels, and the construction efficiency of wall panels of concrete structure is relatively low.

[0003] The existing patent CN201811597792.X discloses a prefabricated wall panel with spiral connection and its assembling method, including a prefabricated wall panel with grooves, a prefabricated wall panel with convex teeth, a rubber water stop strip, and a water stop steel plate. A downward spiral groove is dug with a special tool at the concave and convex parts of the wall to lead the water seeping from the outer wall to the inner wall to flow downward along the spiral groove, so as to avoid the water climbing and spreading inward and causing infiltration to the inner wall. A rubber water stop strip is arranged in the middle part to better block the water from climbing and leaking into the middle section of the wall. A water stop steel plate is welded at the joint of the prefabricated wall panels to block the water flowing along the groove to the outside of the wall and avoid root leakage. This spiral downward water flow method can effectively prevent the water seeping in from the gap from climbing horizontally inward, thus causing the water to seep into the room at the crack between the prefabricated wall panels. In the above patent, water stop is carried out through the water stop steel plate and the rubber water stop strip. The installation of the rubber water stop strip and the water stop steel plate affects the construction of the prefabricated wall panel, and there is no fixed structure between adjacent wall panels, which affects the connection stability of the wall panels.

Bolts pass through the connecting holes and screws pass through the fixing holes to fix the connecting pieces on the upper beam and the lower beam.

[0020] The advantages and positive effects of the adjustable wall panel for prefabricated buildings and its installation method of the present invention are as follows:

[0021] 1. The plates of the present invention are connected to the upper beam and the lower beam through the connecting pieces. The connecting pieces are connected to the clamping grooves on the plates through the clamping blocks, which is convenient for the installation of the plates on the upper beam and the lower beam and is beneficial to improving the assembly efficiency of the wall panels. The connecting pieces are respectively clamped on the two side edges of the upper beam or the lower beam through the first limiting plate, the second limiting plate, the third limiting plate and the fourth limiting plate, which improves the stability of the plates installed on the upper beam and the lower beam. The connecting pieces are fixedly connected to the upper beam or the lower beam through bolts and screws, which is convenient for the disassembly and installation of the connecting pieces.

[0022] 2. The present invention provides a locking structure between adjacent plates. The locking unit of the locking structure is arranged in the middle of the plates, connecting the plates in the middle, which improves the connection strength between adjacent plates. By pushing the locking plate to slide with the second connecting plate and pressing the first connecting plate, the locking connection between two plates can be achieved, which is convenient to operate and beneficial to improving the assembly efficiency of wall panels.

[0023] 3. The present invention is provided with a sealing structure between adjacent plates. While locking the plates, gas is introduced into the first sealing cavity and the second sealing cavity, so that the sealing gasket closely adheres to the first sealing surface and the second sealing surface, improving the sealing effect. The sealing groove provided on the second sealing surface has a certain air pressure, making it more difficult for external gas or rainwater to pass through the connection part of the plates, improving the sealing effect between the plates.

[0024] 4. The wall panel described in the present invention is assembled by plates. The plates are polyester plates, which are light in weight and convenient for transportation. And the length of the wall panel can be adjusted according to needs to meet the assembly requirements of wall panels of different lengths, which is convenient to use.
