Technical Field
[0001] The utility model relates to the field of building curtain walls, and particularly relates to a building curtain wall based on aluminum-plastic composite panels. Background Art
[0002] Traditional building curtain walls have certain technical problems in aspects such as heat insulation, waterproof connection, and anti-offset during splicing. Most of the building curtain walls on the market currently use single metal materials or non-metal materials, which have certain limitations in terms of heat insulation and waterproof performance, and often easily have technical problems such as overheating and water seepage. In addition, the splicing methods of existing building curtain walls are often not convenient enough, and are prone to offset during the splicing process, affecting the building appearance and service life. To solve the above problems, it is necessary to study a new type of building curtain wall structure with good heat insulation and waterproof performance, convenient splicing, and anti-offset, which is the object of research by those skilled in the art. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a building curtain wall based on aluminum-plastic composite panels that is easy to install, has good heat insulation effect, and is waterproof and impermeable in view of the defects and deficiencies of the prior art.
[0004] To achieve the above object, the utility model provides a building curtain wall based on aluminum-plastic composite panels, which includes a wall panel formed by bending the aluminum-plastic composite panel. The wall panel is connected and installed on a base of an exterior wall of a building. The wall panel includes a panel surface and a bending part. The bending part includes a bottom edge and a side panel surface extending and bending from the panel surface. Adjacent two wall panels are combined with an upper clamping seat and a lower clamping seat to form an exterior wall unit of the building curtain wall. The lower clamping seat includes an integrally formed first buckle and a second buckle. The first buckle clamps the bending part of the first wall panel, and the second buckle clamps the bending part of the second wall panel. There is a glue filling cavity in the lower clamping seat between the first buckle and the second buckle. After the glue filling cavity is filled with glue, an upper clamping seat that simultaneously clamps the panel surface of the first wall panel and the panel surface of the second wall panel is provided at the top. The first buckle includes a first arc-shaped spring piece and a first straight spring piece integrally formed with the lower clamping seat. The first arc-shaped spring piece and the first straight spring piece jointly clamp the bending part of the first wall panel. The second buckle includes a second arc-shaped spring piece and a second straight spring piece integrally formed with the lower clamping seat. The second arc-shaped spring piece and the second straight spring piece jointly clamp the bending part of the second wall panel. The surfaces of the first arc-shaped spring piece and the first straight spring piece are both provided with first tapered barbs. The surfaces of the second arc-shaped spring piece and the second straight spring piece are both provided with second tapered barbs. This kind of building curtain wall based on aluminum-plastic composite panels adopts a structural design of clamping the wall panel with the upper clamping seat and the lower clamping seat. This design is not only simple and fast to operate, but also has good waterproof and anti-seepage performance. The surfaces of the first arc-shaped spring piece, the first straight spring piece, the second arc-shaped spring piece and the second straight spring piece are all provided with tapered barbs, which can effectively prevent the offset of the wall panel during the splicing process. Through this structure, the connection between the curtain wall panels is more firm, reducing the potential risks caused by the dislocation or loosening of the wall panel, and ensuring the safety and durability of the curtain wall during long-term use. The glue filling cavity glue filling structure effectively avoids the influence of rainwater corrosion and leakage on the structural performance of the building curtain wall of aluminum-plastic composite panels.
[0005] The upper clamping seat includes a T-shaped main body. The two sides of the main body are respectively provided with a first inclined bracket and a second inclined bracket. The top of the first inclined bracket is provided with a first anti-slip contact point contacting the side panel surface of the first wall panel, and the top of the second inclined bracket is provided with a second anti-slip contact point contacting the side panel surface of the second wall panel, further improving the stability during the use of the curtain wall and enhancing the connection stability among the upper clamping seat, the lower clamping seat and the wall panel.
[0006] The bottom of the glue filling cavity is threadedly connected to the base through a first screw. The base is fixedly connected to the exterior wall of the building. The bottom of the lower clamping seat is provided with a flange covering the surface of the base.
[0007] The described base includes cross beams and longitudinal beams that intersect with each other. Two or more intersecting cross beams and longitudinal beams form spaces, and the first wall panel and the second wall panel are respectively installed in the spaces. The intersection points of the cross beams and longitudinal beams are connected to each other through triangular brackets. Both sides of the triangular brackets are connected to the cross beam or another triangular bracket on the other side of the longitudinal beam through fastening screws. Clamping plates are provided on the sides of the cross beams and longitudinal beams, and two symmetrical clamping plates clamp the bending parts of adjacent two wall panels as the fastening screws are tightened.
[0008] The wall panel is a multi-layer structure, which is from the outside to the inside: fluorocarbon paint surface, primer paint, aluminum substrate, fireproof core material, back aluminum, protective paint, effectively improving the heat insulation performance of the curtain wall and having good waterproof function.
[0009] Adopting the above technical solution, the beneficial effects of the present utility model are:
[0010] 1. The building curtain wall uses aluminum-plastic composite board as the main material, which is from the outside to the inside: fluorocarbon paint surface, primer paint, aluminum substrate, fireproof core material, back aluminum, protective paint. This multi-layer coating structure not only endows the building curtain wall with excellent heat insulation performance, but also enables it to have good waterproof function. Adjacent two wall panels are combined with the upper clamping seat and the lower clamping seat to form the outer wall unit of the building curtain wall, which can effectively block the heat transfer and moisture penetration, thus ensuring the comfort and stability of the internal environment of the building.
[0011] 2. During the installation process of the building curtain wall, a snap structure design is adopted. This design is not only simple and fast to operate and install. Conical barbs are provided on the surfaces of the first circular arc spring piece, the first straight spring piece, the second circular arc spring piece and the second straight spring piece, which can effectively prevent the offset of the wall panel during the splicing process. Through this structure, the connection between the curtain wall panels is more firm, reducing the potential risks caused by the dislocation or loosening of the wall panel, and ensuring the safety and durability of the curtain wall during long-term use.
