[0002] The structure used to connect ALC interior wall panels and steel beams is a key component designed specifically to solve the problem of effective integration of different materials in prefabricated buildings. It usually includes embedded parts, special connection clips, clamps or elastic connection elements, and realizes rigid or flexible connection between ALC wall panels and steel beams through bolts, welding and other means. The design of this type of structure takes into account the requirements of load-bearing capacity transmission, structural stability, deformation coordination and seismic performance, ensuring that ALC wall panels can be reliably attached to steel beams under various load conditions, while allowing moderate displacement caused by temperature differences to prevent cracks or damage caused by rigid connections. In addition, it also has the advantages of improving construction efficiency and reducing costs, and plays a vital role in the quality assurance and structural safety of modern industrialized buildings.

[0003] After searching, the patent number "CN209670095U" mentioned in the text that "the utility model discloses a fireproof connection structure of ALC inner wall and steel beam of steel structure residential building, which relates to the field of prefabricated building technology. The steel beam is supported at the bottom of the floor slab, and the ALC inner wall is arranged under the steel beam to form a gap with the steel beam. The rock wool board is filled in the gap, and its outer side is filled and smoothed with caulking agent; the ALC thin plate includes a bottom thin plate arranged at the bottom of the steel beam and side thin plates arranged on both sides of the steel beam. The ALC inner wall is arranged through the bottom thin plate, and the bottom thin plate is connected and fixed to the two side thin plates by respective nails. The utility model uses inorganic material ALC to form ALC inner wall and ALC thin plate, and uses ALC thin plate to cover the steel beam to meet the fire protection requirements of the building; the rock wool board is soft and deformable, and has the characteristics of non-combustibility and low thermal conductivity. Rock wool boards are used to fill the gaps between ALC inner walls and steel beams to meet the requirements of building fire prevention and heat insulation; the structure is simple, the construction is convenient, the cost is low, and it has good practicality. When in use, the inorganic material ALC is used to form ALC inner walls and ALC thin plates, and the steel beams are covered with ALC thin plates to meet the fire prevention requirements of the building. The rock wool boards are soft and deformable, non-flammable and have low thermal conductivity. The gaps between the ALC inner walls and steel beams are filled with rock wool boards to meet the requirements of building fire prevention and heat insulation. However, although the structure is simple and the construction is convenient, the seismic performance of the connection structure under earthquakes or other dynamic loads is not clearly stated. In particular, under the action of high-intensity earthquakes, the firmness of the connection between the ALC thin plates and the steel beams and the stability of the rock wool boards at the gaps are not enough to resist the relative displacement.

[0004] To this end, we provide a structure for connecting ALC inner walls and steel beams to solve the above problems. Utility Model Content

One side of the main connecting member 1 is fixedly connected to the connecting mechanism 2. The connecting mechanism 2 is the core component of the entire structure and integrates fire prevention, heat preservation, thermal insulation, and fixing functions to ensure an effective and secure connection between the ALC interior wall and the steel beam 242.

[0028] The connecting mechanism 2 includes a fireproof isolation component 21 arranged on one side of the main connecting component 1. The fireproof isolation component 21 provides fire protection and preliminary heat insulation effects to prevent the spread of fire and reduce heat transfer. A thermal insulation component 22 is arranged on the inner side of the fireproof isolation component 21. The thermal insulation component 22 enhances the thermal insulation and heat insulation performance of the structure and reduces the energy consumption of the building. A fixing component 23 is arranged on the inner side of the thermal insulation component 22. The fixing component 23 provides a stable support and fixing environment for the steel beam component 24. The inner side of the fixing component 23 is fixedly connected to the steel beam component 24.

[0029] In the present invention, the fireproof isolation component 21 includes a decorative layer 211 fixedly connected to one side of the main connecting member 1. The decorative layer 211 has a decorative and beautifying effect, and can also play a certain fireproof isolation effect to prevent the fire source from spreading rapidly to the internal structure. The inner side of the decorative layer 211 is fixedly connected with an aerogel felt 212. As a high-efficiency thermal insulation material, the aerogel felt 212 can effectively prevent heat transfer and enhance fireproof performance. The inner side of the aerogel felt 212 is fixedly connected with a mineral wool board 213. The mineral wool board 213 also has good fireproof and sound insulation properties, further enhancing the fireproof isolation effect.

[0030] In the present invention, the thermal insulation component 22 includes a polyurethane foam layer 221 fixedly installed on one side of the mineral wool board 213. The polyurethane foam layer 221 has excellent thermal insulation performance and can effectively reduce heat loss or block the introduction of external high temperature. The other side of the polyurethane foam layer 221 is fixedly connected to a rock wool layer 222. The rock wool layer 222 provides excellent thermal insulation and heat preservation effects, and has a certain sound absorption and noise reduction function. The other side of the rock wool layer 222 is fixedly connected to a vacuum insulation panel 223. The vacuum insulation panel 223 uses the vacuum insulation principle to greatly improve the insulation efficiency and reduce heat conduction.

[0031] In the present invention, the fixing assembly 23 includes a fixing mesh 231 arranged on the other side of the vacuum insulation panel 223. The fixing mesh 231 is used to reinforce and support the internal filling material to ensure the overall stability of the structure.

The steel plate 31 enhances the local stiffness and bearing capacity of the steel beam 242, and achieves effective connection with the original structure through the expansion bolts 32. The expansion bolts 32 provide strong tensioning force to ensure a tight connection and load transfer between the steel plate 31 and the steel beam 242. The shear key 33 increases the shear resistance of the structure to prevent shear damage at the connection part. The ALC wall panel 34, as the final wall structure, is firmly fixed to the lower end of the steel beam 242 through the flexible buffer gasket 251 and the ALC wall panel fixing slot 252 to form a strong and durable wall structure.

The fixing component 23 adopts a combination of fixed mesh 231 and cement 232 to provide a stable supporting environment for the steel beam component 24. The filler 241 in the steel beam component 24 ensures that the steel beam 242 is tightly combined with the fixing component 23, thereby enhancing the stability of the overall structure. The steel beam 242 serves as the load-bearing body, bears the upper structure load and transmits it to the foundation through itself. The flexible buffer gasket 251 can absorb and disperse the stress caused by temperature changes and load changes, protecting the steel beam 242 and the ALC wall panel 34 from damage. The ALC wall panel 34 is accurately installed at the lower end of the steel beam 242 through the ALC wall panel fixing slot 252, realizing effective connection and buffering between the wall and the structure. In some embodiments, a reinforcement component 3 is added, and the steel plate 31 is tightly connected to the inner side of the steel beam 242 through the expansion bolt 32, thereby improving the local stiffness and bearing capacity of the steel beam 242.
