Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled building component. Background Art

[0002] At present, composite panels are a kind of high-performance building panels composed of multiple materials. They have the advantages of stable quality and environmental protection. They are the preferred materials for modern prefabricated building exterior wall panels. With the development of building materials, composite panels are more and more widely used in production and life. When composite panels are used as panels for building exterior walls, in order to facilitate their installation and construction, multiple composite panels are usually used to assemble a larger area of ​​wall. In order to ensure that the joints are airtight, wind-proof, and rain-proof, joints are usually provided at the joints of the composite panels. The joints of existing composite panels are usually more complicated, and there will be exposed joints at the ends of the wall, or the joints at the installation positions of the door and window frames need to be cut. On-site cutting is not easy to handle and is prone to defects such as dimensional deviation, deflection, and burrs. It is often necessary to install side sleeves or set frame profiles for processing. Existing composite panels are generally connected to side sleeves or frame profiles by welding or gluing, which is inconvenient to install and disassemble, and the welding process is complicated and the adhesive connection is easy to debond.

[0003] In order to solve the problem of inconvenient installation of composite panels and frame profiles, a process or device for completely hooking the edge of the composite panel is generally adopted. For example, the Chinese patent document with publication number CN 113431283A discloses a composite wall panel, which includes a composite panel and a frame profile. The frame profile includes an outer panel, a first bottom panel and an inner panel. The outer panel has a concave slot. The composite panel includes an outer panel, a core panel and an inner panel. The outer panel is bent along the frame profile and folded inward to form a hook, which is engaged with the concave slot. The composite wall panel clamps and fixes the composite panel and the frame profile. Although it can realize the fixed installation of the frame profile, since the frame profile needs to be installed by hooking, it is easy to cause damage to the edge of the composite panel and deformation and damage of the frame profile during disassembly. During actual construction, on the one hand, the installation and disassembly of the frame profile is relatively inconvenient, and on the other hand, the installation and disassembly of the composite wall panel and the frame are also relatively inconvenient.
