Description

Fixing device is connected to assembled building structure side fascia Technical Field The utility model relates to the technical field of buildings, in particular to a connecting and fixing device for an external wall board of an assembled building structure. Background In the field of assembled building, ALC (autoclaved aerated concrete plate) external wall panels are widely applied to building exterior wall decoration and building envelope due to the excellent performances of light weight, heat preservation, heat insulation, sound insulation and the like. However, how to efficiently and firmly fixedly connect the ALC external wall panel to the main wall is always a technical problem to be solved in the industry. The traditional external wall panel fixing mode has a plurality of defects. For example, a part of fixing modes adopt on-site wet operation, and the connection is realized by pouring materials such as concrete mortar between a main wall body and an external wall board, so that the wet operation mode has long construction period, is greatly influenced by weather and environmental factors, is difficult to ensure construction quality, easily has quality problems such as hollowing and cracking, and influences the overall performance and the aesthetic degree of a building. Disclosure of utility model The utility model aims to provide an external wall board connecting and fixing device of an assembled building structure, which is used for efficiently, quickly, firmly and reliably fixedly connecting an ALC external wall board to a main wall body. In order to achieve the above purpose, the utility model adopts the technical scheme that the connecting and fixing device for the external wall panel of the assembled building structure comprises: The corner connector is fixed on the main wall body through an expansion screw; The connecting plate is fixed on the corner connector and provided with a plurality of connecting holes; The hook bolts penetrate through the ALC external wall plate, thread sections of the hook bolts penetrate through connecting holes of the connecting plate, and the hook bolts are fastened on the connecting plate through nut locks. In one embodiment, the corner brace is disposed on the main wall body at the upper and lower ends of the area connected with the ALC external wall panel. In one embodiment, the connection plate is a high strength metal plate. In one embodiment, the device further comprises a cement layer, wherein the cement layer covers the corner bracket, the connecting plate and the exterior of the hook bolt. In one embodiment, the aluminum alloy outer wall panel further comprises an adhesive layer, wherein the adhesive layer is arranged in a gap between the corner brace and the main wall body and in a gap between the connecting plate and the aluminum alloy outer wall panel. In one embodiment, the hook portion and the straight rod portion of the hook bolt are both provided with an anti-slip structure. The above-mentioned one or more technical solutions in the embodiments of the present utility model at least have the following technical effects or advantages: According to the connecting and fixing device for the external wall panel of the assembled building structure, the corner connector is fixed on the main wall body by using the expansion screw, the connecting plate is fixed on the corner connector by adopting convenient modes such as welding or threaded connection, and finally the hook bolt penetrates into a through hole preset in the ALC external wall panel and is fixedly connected to the connecting plate by using the nut locking. The whole installation process is simple to operate, complicated wet operation is not needed, the construction period is greatly shortened, the construction efficiency is improved, and the requirement of quick construction of modern assembly type buildings can be effectively met. And the corner connector is firmly fixed on the main wall body through the expansion screw, thereby providing a solid foundation for the whole connecting structure. After the hook bolt penetrates through the ALC external wall panel, the threaded section of the hook bolt is inserted into the connecting hole of the connecting plate and locked and fixed through the nut, and the connecting mode can ensure that reliable connection is formed between the ALC external wall panel and the main wall body, so that the structural safety and stability of a building are ensured. Drawings In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings that are needed in the embodiments or the description of the prior art will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present utility model, and that other drawings can be obtained according to these drawings without inventive effort for a person skilled in the art.
