Description

Technical Field

[0001] The utility model belongs to the technical field of composite boards, and particularly relates to a building flat composite board. Background Art

[0002] Composite board is a new type of board made of two or more different materials combined by physical or chemical means. In the field of construction, composite boards are usually used to combine the advantages of various materials, such as strength, fire resistance, thermal insulation, moisture resistance, etc., to meet different building design and construction requirements. Building flat composite board refers to a composite board suitable for wall decoration or partition walls, which is characterized by being directly laid flat on the base wall without the need for additional skeleton support. This type of composite board may include but is not limited to wood composite board, gypsum composite board, metal-coated composite board, stone composite board and other types.

[0003] Existing flat-pasted composite panels in buildings are mechanically assembled using screws or nails. Screw fixation requires pre-drilling and tightening of screws one by one, and nails also need to be precisely aligned and fired. These steps may lead to slow installation and high labor intensity. Continuous drilling and driving screws or nails may damage the internal structure of the composite panel and cause stress concentration at the fixing point, which may cause material fatigue cracks over time. At the same time, the fixed holes can easily become a path for moisture and air infiltration, affecting the thermal insulation and waterproof properties. Utility Model Content

[0004] In view of this, the utility model aims to provide a building flat composite panel to address the deficiencies in the prior art. The spring-driven quick assembly method can achieve tool-free or low-tool operation, greatly shortening the installation time, improving work efficiency, avoiding stress concentration and potential damage caused by direct punching, and is beneficial to maintaining the integrity of the composite panel and extending its service life, and helps to improve the air tightness and water tightness of the overall structure.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a building flat-pasted composite panel, including a frame panel, a decorative layer is arranged on the inner front side of the frame panel, a wear-resistant layer is arranged on the inner rear side of the frame panel, a high-density fiberboard layer is bonded to the rear side of the decorative layer, an oriented strand board layer is bonded to the rear side of the high-density fiberboard layer, a left and right mounting mechanism is arranged on the right side of the frame panel, upper and lower mounting components are arranged on the upper and lower ends of the frame panel respectively, a balancing layer is bonded to the upper end of the oriented strand board layer, a fireproof layer is bonded to the upper end of the balancing layer, a waterproof layer is bonded to the upper end of the fireproof layer, and the upper end of the waterproof layer is bonded to the lower end of the wear-resistant layer, and the left and right mounting mechanisms include two docking notches opened on the right side of the frame panel, and the two docking notches are provided. The interior of the two sliding columns is slidably connected with sliding columns, and plug blocks are provided on the opposite inner ends of the two sliding columns. Two rectangular blocks are provided on the left side of the frame plate and are installed in cooperation with the docking grooves. Slots that are installed in cooperation with the plug blocks are provided inside the two rectangular blocks. The threaded outer surfaces of the two sliding columns that are opposite to the outer ends are threadedly connected with internal threaded tubes, and an elastic driving component is provided between the plug blocks and the interior of the docking grooves. Auxiliary mounting components are provided on the opposite outer surfaces of the two internal threaded tubes, and the elastic driving component includes a spring provided on the two springs, which are respectively sleeved on the corresponding outer arc surfaces of the sliding columns, and the auxiliary mounting component includes pull plates respectively provided on the opposite outer surfaces of the two internal threaded tubes.

[0006] As a further improvement of the present invention, the upper and lower mounting components include mounting plates respectively arranged on the upper and lower sides of the frame plate, and a plurality of mounting holes are provided inside the mounting plates.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0008] First, by pulling the pull plates on both sides, the springs on both sides are in a compressed state, and then the rectangular block on the other frame plate is inserted into the inside of the docking groove, and then the pull plate is released. At this time, the spring rebounds quickly to drive the plug on the sliding column to insert into the slot on the rectangular block. The spring-driven quick assembly method can achieve tool-free or low-tool operation, greatly shortening the installation time, improving work efficiency, avoiding stress concentration and potential damage caused by direct punching, which is beneficial to maintaining the integrity of the composite board and extending its service life, and helps to improve the air tightness and water tightness of the overall structure.

[0009] Secondly, the decorative layer makes the composite board beautiful, the wear-resistant layer can withstand the friction and impact of daily use, ensuring that the surface is not easy to wear and fade, the high-density fiberboard layer and the oriented strand board layer provide good stability and carrying capacity. The high-density fiberboard layer has higher mechanical strength due to its compact structure, and the particle board layer performs better in the direction of force through the directional arrangement of wood chips. The balancing layer helps to maintain the stability of the composite board and reduce the risk of deformation due to moisture, especially in an environment with large changes in humidity. It can prevent the board surface from warping or arching, which can extend the service life of the composite board.

[0010] Thirdly, the fireproof layer can delay the spread of fire, improve the safety of buildings, and meet the requirements of relevant building codes for flame retardancy of building materials. The waterproof layer can prevent moisture from penetrating from the outside to the inside, ensuring that the composite board can still maintain good performance in a humid environment, preventing decay and mildew, and making the composite board have a stronger protective effect.

[0011] Fourthly, the upper and lower sides of the composite panel can be quickly installed by using the mounting holes inside the mounting plate in conjunction with rivets, making it easy for personnel to assemble the upper and lower sides. BRIEF DESCRIPTION OF THE DRAWINGS
