Description

Technical Field

[0001] The utility model relates to the technical field of composite boards, in particular to a PVC composite board which is easy to splice. Background Art

[0002] Sheets are flat rectangular building material boards made into standard sizes and used in the construction industry as components of walls, ceilings or floors. They also refer to metal sheets that are forged, rolled or cast. The lightweight sheets currently on the market are mainly made of wood, which has poor flame retardancy and sound insulation, and are not easy to splice and fix.

[0003] A Chinese patent with application number 202220148601.7 discloses a composite lightweight board that is easy to splice, which relates to the field of board technology. The following scheme is proposed, including a lightweight board body and a fixed plate, wherein a fixing groove is opened on the outer wall on one side of the lightweight board body, and a connecting groove is opened on the outer wall on one side of the lightweight board body, a limiting groove is opened on the top outer wall of the lightweight board body, and a connecting plate is welded to the top outer wall of the fixed plate, a limiting plate is welded to the top outer wall of the connecting plate, a first threaded through hole is opened on the bottom inner wall of the limiting groove, and second threaded through holes are opened at both ends of the top outer wall of the limiting plate. The utility model effectively improves the sound insulation and flame retardant properties of the board by providing a sound insulation layer and a flame retardant layer, making the board more effective and safer to use. By providing a fixing plate, a fixing groove, a connecting plate, a connecting groove, a limiting plate and a limiting groove, the splicing of every two lightweight boards is simple, the alignment is accurate, and the fixation is convenient. However, there are still some deficiencies in the implementation of this patent. This patent splices and installs two boards through a fixing plate and a bolt. When using and installing, the staff needs to screw two bolts into the threaded holes for fixed connection, which results in the need to screw the bolts into the threaded holes during the connection and installation, resulting in cumbersome operation during splicing and installation, resulting in low splicing efficiency. At the same time, a gap is generated between the fixing plate and the composite board after splicing, thereby affecting the aesthetics of the board after splicing. At the same time, this patent only connects the middle position of the two composite boards through the fixing plate, and the connecting surface is small, which leads to the problem of poor stability between the boards after connection.
