Description

Technical Field

[0001] The present invention relates to a wall and an installation method thereof, and in particular to an assembled wall and an installation method thereof. Background Art

[0002] Prefabricated walls refer to walls that are pre-fabricated in a factory and transported to the construction site for direct assembly. Compared with cast-in-place walls directly at the construction site, they have the characteristics of fast construction speed, more stable quality, and environmental protection.

[0003] Current prefabricated walls often utilize lightweight steel keels as their framework and OSB boards as their enclosure to enhance their overall stability. However, these structures are relatively complex, resulting in low installation efficiency. Furthermore, they suffer from common issues such as large wall volume, poor lateral resistance, and weak seismic and energy-absorbing capabilities. Therefore, exploring effective prefabricated wall design methods to achieve modularity, lightweight construction, and enhanced seismic and energy-absorbing capabilities has become a pressing issue. Summary of the Invention

[0004] The main purpose of the present invention is to solve the many problems commonly found in existing prefabricated walls, such as large volume, poor lateral resistance and weak shock absorption and energy dissipation capacity, and to provide a prefabricated wall and its installation method.

[0005] The assembled wall provided by the present invention comprises two or more prefabricated wall panels, which are connected to form an integral structure to form an assembled wall of set specifications.

[0006] The sides between adjacent prefabricated wall panels are filled with rubber pads, and the upper and lower ends of the assembled wall and the upper and lower joints of adjacent prefabricated wall panels are equipped with U-shaped guide rails.

[0007] The U-shaped guide rail is connected to the assembled wall through self-tapping screws.

[0008] Each prefabricated wall panel includes two U-shaped channel steels and special-shaped steel plates, wherein a U-shaped curling edge is provided on one side of both sides of the special-shaped steel plate, and the two U-shaped channel steels are respectively fixedly connected to the side without curling edges on both sides of the special-shaped steel plate. The size of the U-shaped channel steel corresponds to the size of the U-shaped curling edge. The U-shaped channel steel and the U-shaped curling edge form corresponding slots on the front and back of both sides of the special-shaped steel plate, and a straw board, rock wool or polystyrene board of the same thickness as the slot is inserted into the slot.

[0009] The U-shaped channel steel and the special-shaped steel plate are fixedly connected by self-tapping screws and then welded.

[0010] The front and rear sides of the assembled wall are covered with steel mesh, and the outside of the steel mesh is plastered with cement mortar to form the assembled wall into an integral structure.

[0011] The present invention provides a method for installing an assembled wall, which comprises the following steps:

[0012] The first step is to connect the special-shaped steel plate and two U-shaped channel steels. The two U-shaped channel steels are fixed to the two sides of the special-shaped steel plate without curling. The flanges of the U-shaped channel steel and the web of the special-shaped steel plate are connected by self-tapping screws. The same row of self-tapping screws are driven in from the front and back sides respectively. The joints between the U-shaped channel steel and the special-shaped steel plate on the left and right sides are welded;

[0013] The second step is to embed straw boards or rock wool or polystyrene boards of the same thickness as the grooves into the two corresponding grooves formed on both sides of the special-shaped steel plate and the front and rear grooves of the U-shaped channel steel;

[0014] Step 3: Place the U-shaped guide rail on top of the foundation beam or frame beam according to the set position and connect it with anti-pull bolts;

[0015] Step 4: Push the prefabricated wall panels in sequence along the length of the U-shaped guide rail. Fill the vertical joints of adjacent prefabricated wall panels with rubber pads. The upper and lower ends of the prefabricated wall and the upper and lower joints of adjacent prefabricated wall panels are equipped with U-shaped guide rails. The side flanges of the U-shaped guide rails are connected to the prefabricated wall with self-tapping screws.

[0016] The fifth step is to hang steel mesh on the inner and outer surfaces of the prefabricated wall, use self-tapping screws to connect the steel mesh to the prefabricated wall, and then use cement mortar to plaster the steel mesh to form an integral structure of the prefabricated wall.

[0017] Beneficial effects of the present invention:

[0018] (1) The prefabricated wall provided by the present invention combines and connects components such as special-shaped steel plates and U-shaped channel steels to form the main frame for installing the insulation board. Each component and the insulation board can be prefabricated and does not require on-site processing, making the insulation board easy to install and simplifying the installation process of the insulation board;

[0019] (2) The installation method provided by the present invention is less affected by the wall structure, has good adaptability to the wall, and the insulation board has high flatness after installation;

[0020] (3) The rubber pads placed at the vertical joints of adjacent prefabricated wall panels provided by the present invention can improve the deformation and energy dissipation capacity of the wall and increase the overall stability;

[0021] (4) All components in the present invention can be produced in a factory, and only self-tapping screws are used to complete the installation between the components, which not only simplifies the construction but also greatly shortens the construction period.
