Description

Technical Field

[0001] This utility model relates to the field of construction, specifically to an ALC splicing large panel connection structure. Background Technology

[0002] Building construction is a lengthy process. With the development of the construction industry, autoclaved lightweight concrete (ALC) panels were invented to improve construction efficiency. ALC panels can be used as wall materials. When building construction, it is only necessary to prefabricate ALC panels and then splice them with the base beam structure, which greatly increases the efficiency of building construction.

[0003] However, ALC panels have diverse splicing structures, and many splicing structures cannot meet the required strength requirements. In disaster-prone areas, splicing area breakage is likely to occur, resulting in poor safety of ALC panel spliced ​​buildings. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an ALC splicing large panel connection structure that ensures the strength of the ALC panel splicing structure and has a certain disaster resistance.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: an ALC splicing large panel connection structure, including an ALC splicing large panel, wherein the ALC splicing large panel is a surface layer structure, the lower end of the ALC splicing large panel is fixedly connected to a concrete beam, the upper end of the ALC splicing large panel is fixedly connected to a cast-in-place beam, and the ALC splicing large panel and the concrete beam are fixedly connected by a metal connecting component.

[0006] Compared with the prior art, the advantages of this utility model are as follows: In the process of splicing ALC splicing panels and concrete beams, metal connecting components are added to strengthen the splicing strength between ALC splicing panels and concrete beams, and to form a fixed connection between ALC splicing panels and concrete beams. This avoids the problem of insufficient strength of simple splicing structures, and makes buildings constructed with ALC splicing panels have a certain disaster resistance capability, making them suitable for disaster-prone areas.

[0007] As an improvement of this utility model, the metal connection assembly includes a concrete embedded part pre-embedded in the concrete beam, a connecting plate fixedly connected to the ALC splicing plate, and a connecting angle steel. One side of the connecting angle steel is welded and fixed to the concrete embedded part, and the other side of the connecting angle steel is welded and fixed to the ALC splicing plate. Through this improvement, the fixed connection between the ALC splicing plate and the concrete beam is achieved by fixing the connecting angle steel to the concrete embedded part and the connecting plate respectively. The concrete embedded part is pre-embedded in the concrete beam, which ensures the tightness of the connection between the concrete embedded part and the concrete beam, thereby ensuring the fixed connection effect of the metal connection assembly.

[0008] As an improvement of this utility model, the concrete embedded part is provided at one end of the concrete beam near the ALC splicing plate, and the connecting plate is provided at one end of the ALC splicing plate near the concrete beam. Both the concrete embedded part and the connecting plate are located on the inner side of the surface structure. Through this improvement, the concrete embedded part and the connecting plate are concentrated on the inner side of the surface layer, which facilitates the welding process and avoids the risk of falling during work on the outside of high-rise buildings.

[0009] As an improvement of this utility model, the ALC splicing panel is provided with a connecting groove, the connecting plate is disposed in the connecting groove, the connecting side of the connecting angle steel and the ALC splicing panel is also disposed in the connecting groove, and the connecting plate is disposed between the connecting angle steel and the ALC splicing panel. Through this improvement, after the splicing and fixing of the ALC splicing panel and the concrete beam is completed, the wall surface maintains a non-protruding structure, ensuring the aesthetics of the wall surface and improving the living experience of the residents.

[0010] As an improvement of this utility model, the connecting plate is fixedly connected to the ALC splicing plate by a flat bolt. The flat bolt passes through the ALC splicing plate, and the nut that is fixed to the flat bolt is also located in the connecting groove. Through this improvement, the connecting plate and the ALC splicing plate are fixedly connected, while still maintaining a wall surface without any protruding structures, ensuring the aesthetics of the wall surface and improving the living experience of the residents.

[0011] As an improvement of this utility model, the concrete embedded part includes a welding plate and a fixing reinforcing bar. The upper end of the welding plate is welded and fixed to one side of the connecting angle steel, and the other end of the welding plate is welded and fixed to the fixing reinforcing bar and then embedded in the concrete beam. The fixing reinforcing bar is fixed in the concrete beam in a hook shape. Through this improvement, the welding plate is used to weld with the connecting angle steel to ensure sufficient welding area, thereby ensuring welding quality. The hook-shaped fixing reinforcing bar is used to ensure the connection strength of the concrete embedded part in the concrete beam and prevent the concrete embedded part from detaching from the concrete beam.

[0012] As an improvement of this utility model, alkali-resistant fiberglass mesh is adhered to both the inner and outer sides of the connection between the ALC splicing panel and the concrete beam. The alkali-resistant fiberglass mesh is laid in a planar manner. Through this improvement, the splicing marks between the ALC splicing panel and the concrete beam are eliminated, and the mechanical strength of the wall surface is improved, ensuring the continuity of the wall surface's resistance, dispersing the shrinkage pressure and thermal insulation stress of the wall surface, avoiding stress concentration, and effectively resisting wall surface cracking caused by temperature and humidity changes and accidental impacts.

[0013] As an improvement of this utility model, a connecting grout is injected between the ALC splicing plate and the concrete beam. Through this improvement, the splicing gap between the ALC splicing plate and the concrete beam is eliminated, making the structure of the ALC splicing plate and the concrete beam integrated, and further enhancing the splicing strength between the ALC splicing plate and the concrete beam.

[0014] As an improvement of this utility model, the ALC splicing plate is provided with grouting holes for injecting connecting grout. The grouting holes are designed at an angle, and the injection of connecting grout is achieved through this improvement.

[0015] As an improvement of this utility model, a pre-reserved steel bar is provided at one end of the connection between the ALC splicing panel and the cast-in-place beam. Alkali-resistant fiberglass mesh is adhered to both the inner and outer sides of the connection between the ALC splicing panel and the cast-in-place beam. The alkali-resistant fiberglass mesh is laid in a planar manner. Through this improvement, a fixed connection between the ALC splicing panel and the cast-in-place beam is achieved. Since the cast-in-place beam is formed on-site based on the ALC splicing panel, there is no need to worry about the integral continuity between the ALC splicing panel and the cast-in-place beam. The alkali-resistant fiberglass mesh eliminates the mechanical strength of the wall surface between the ALC splicing panel and the cast-in-place beam, ensuring the continuity of the wall surface resistance, dispersing the shrinkage pressure and thermal insulation stress of the wall surface, avoiding stress concentration, and effectively resisting wall surface cracking caused by temperature and humidity changes and accidental impacts.
