[0002] Prefabricated buildings in my country have developed into a new type of construction method that is systematic, standardized and technological. Prefabricated buildings are widely used in many fields, from single houses to apartment buildings, villas, schools, hospitals and commercial buildings. Among them, prefabricated steel structures and prefabricated autoclaved aerated concrete (AAC) maintenance systems have been the mainstream trend in recent years.

[0003] At present, there are still some problems in the promotion of prefabricated buildings, such as the incompleteness of relevant standards and specifications, construction problems, etc. It is urgent to improve and perfect relevant laws, regulations, standards and specifications to ensure the quality and safety of prefabricated buildings. The structural system of this project is a prefabricated steel frame structure, and the enclosure wall is in the form of an assembled autoclaved aerated concrete panel (AAC) towed outside the steel structure. Its form is novel and the practice is uncommon. In addition, the height of the enclosure wall is 11.7 meters, and there is a gap of 5 to 10 centimeters between it and the main structure, and there is no structural member in the middle to support it. In the prior art, after the main frame of the steel beam is overlapped, the entire AAC wall panel is fixed to the main frame of the steel beam through a special connector, but the gap between the AAC wall panel and the main frame of the steel beam is fixed and cannot be adjusted. If the bearing capacity is large and the strength is low, it is easy to bend and break. This type of connector has a complex structure and is not easy to purchase. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a steel structure external supporting AAC wall panel connection device, which divides the whole AAC wall panel into multiple AAC wall panels. The upper and lower adjacent AAC wall panels are fixed on the steel beam through the connection device. The structure is compact, the gap between the AAC wall panel and the steel beam can be adjusted, and the whole structure is firm and stable with high safety.

[0005] The utility model is realized by the following technical solutions:

[0006] A steel structure external support AAC wall panel connection device, comprising a support plate, two angle steels, and two hook bolts, wherein the bottom surface of one end of the support plate is used to be fixed on the upper flange surface of the steel beam;

[0007] The other end of the support plate is used to be placed in the joint gap of the upper and lower adjacent AAC wall panels, the horizontal edges of the two angle steels are respectively fixed to the upper and lower surfaces of the support plate, and the vertical edges of the two angle steels are used to fit on the surfaces of the upper and lower adjacent AAC wall panels;

[0008] The screw sections of the two hook bolts are used to respectively penetrate the upper and lower adjacent AAC wall panels, and the hook ends of the two hook bolts are used to press the vertical edges of the angle steel and fix the connection.

[0009] Furthermore, the angle steel is a full-length angle steel, and the support plate is a long steel support plate.

[0010] Furthermore, the horizontal sides of the full-length angle steel are welded to the surface of the steel support plate.

[0011] Furthermore, the hook ends of the two hook bolts are welded to the outer side surface of the vertical edge of the full-length angle steel.

[0012] Furthermore, the support plate is made of Q355B steel plate with a thickness of 1-1.5 cm.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are as follows:

[0014] 1. The whole AAC wall panel is divided into multiple AAC wall panels. When the upper and lower adjacent AAC wall panels are connected to the steel beam, the steel structure external support AAC wall panel connection device of the utility model is used for connection and fixing, so that the AAC wall panel is fixed to the steel beam. By fixing the angle steel at different positions on the support plate, the gap distance between the AAC wall panel and the steel beam main frame can be changed. The structure is compact, and each AAC wall panel is firmly and stably pulled up as a whole, with high safety.

[0021] like Figure 1-2 As shown, this embodiment discloses a steel structure external support AAC wall panel connection device, which mainly includes a support plate, two angle steels, and two hook bolts 3. The support plate uses a long steel support plate 1, which is a Q355B steel plate with a thickness of 1 cm, and its length is selected according to the thickness of the AAC wall panel 5 and the preset spacing with the steel beam 4. The angle steel uses a full-length angle steel 2, and the specification is selected from L63*63*8, Q235B hot-dip galvanized angle steel, and the hook bolt 3 uses a specification of M12 hook bolt.

[0022] Different from the prior art method in which the whole AAC wall panel is integrally hung on the steel beam through the connecting piece to form the wall, in this embodiment, the whole AAC wall panel is divided into a plurality of AAC wall panels 5, which are connected to the steel beam by the AAC wall panel connecting device supported by the steel structure. The specific steps are as follows:

[0023] S01. Weld the steel support plate 1 to the upper flange of the steel beam 200mm, with a cantilever length of 200mm. The cantilever length shall not be greater than the welding length. Set one steel support plate 1 at a spacing of 600mm.

[0025] S03. The screw sections of the two hook bolts 3 are used to respectively pass through the middle of the upper and lower adjacent AAC wall panels 5. The hook ends of the two hook bolts are used to press the vertical edges of the angle steel and weld them into one.
