Steel structures, as a high-assembly rate and factory-based structural form, have also been increasingly used. The combination of the two has become the direction of future buildings.
[0003] In traditional methods, it is difficult to connect the building's external insulation layer with the steel beams and columns, and the construction quality is difficult to guarantee. At the same time, due to the fast heat transfer of the steel structure material itself, many thermal bridges are generated at the steel beams and columns, which is not conducive to achieving the near-zero energy building standard. Utility Model Content

[0007] By adopting the above technical solution, autoclaved aerated concrete blocks are used to avoid direct contact between the steel structure and the insulation layer. Since the autoclaved sand aerated blocks have a heat insulation function, the thermal bridge effect at the steel structure can be blocked as much as possible, so that the steel structure building meets the near-zero energy consumption building standard.

[0009] By adopting the above technical solution, by setting corner protection lines, it is possible to provide a certain degree of protection for the corners of the insulation layer, effectively ensuring that the structural integrity of the insulation layer is maintained to the greatest extent, thereby ensuring the long-term stability of the insulation layer as much as possible.
[0010] Preferably, an alkali-resistant mesh cloth is provided in the thermal insulation layer, and the alkali-resistant mesh cloth is laid on a side of the thermal insulation layer away from the steel structure.
[0011] By adopting the above technical solution and providing an alkali-resistant mesh cloth, the generation of cracks on the thermal insulation layer can be effectively prevented, thereby avoiding adverse effects on the thermal insulation effect of the thermal insulation layer.
[0012] Preferably, both side edges of the alkali-resistant mesh cloth near the building corners extend toward the insulation layer of the adjacent exterior walls, and a double-layer overlapping structure is formed at the building corners.
[0013] By adopting the above technical solution and utilizing a double-layer overlapping structure, the integrity and continuity of the alkali-resistant mesh cloth laid on the insulation wall can be ensured, thereby improving the protective effect of the insulation layer.
[0014] Preferably, an airtight layer is provided on the side of the autoclaved aerated concrete block close to the room.
[0015] By adopting the above technical solution, the heat exchange between indoor and outdoor can be significantly reduced by setting an airtight layer, effectively reducing the heat transfer through the building envelope structure, thereby improving the building's thermal insulation performance.
[0016] Preferably, the fixing member is configured as a thermal insulation anchor bolt, one end of which penetrates the insulation layer and is fixedly disposed in the autoclaved aerated concrete block.
[0017] By adopting the above technical solution, the use of thermal insulation anchor bolts can ensure a stable connection between the insulation layer and the autoclaved aerated concrete blocks, effectively preventing the insulation layer from shifting and peeling, thereby improving the building's wind pressure resistance and enhancing its thermal insulation performance.

[0022] The following is combined with Figure 1-2 This application is described in further detail.
[0023] The embodiment of the present application discloses a steel structure near-zero energy consumption building enclosure system.
[0024] Reference Figure 1 and Figure 2 A steel structure near-zero energy building envelope system includes an autoclaved aerated concrete block 1, which is arranged between an insulation wall and a steel structure, wherein the steel structure includes a steel beam 101 and a steel column 100, thereby avoiding direct contact between the steel structure and an insulation layer 102, thereby blocking the thermal bridge effect at the steel structure as much as possible, so that the steel structure building meets the near-zero energy building standard.
[0025] The autoclaved aerated concrete block 1 has the effect of saving energy and protecting the environment. It is a new type of lightweight green environmentally friendly non-load-bearing wall with superior performance, and the autoclaved aerated concrete block 1 in this embodiment can also be set as an autoclaved aerated concrete strip board. The autoclaved aerated concrete block 1 can achieve the heat insulation function, so that the building can meet the building standard of near-zero energy consumption. The autoclaved aerated concrete block 1 is arranged on the outer side of the steel beam 101 and the steel column 100 close to the insulation layer 102, and is arranged on the upper and lower sides of the floor 103. The autoclaved aerated concrete block 1 is fixedly connected to the insulation layer 102 through the fixing member 2. In this embodiment, the fixing member 2 is set as a thermal insulation anchor bolt. One end of the fixing member 2 passes through the insulation layer 102 and is fixed in the autoclaved aerated concrete block 1, so that the insulation layer 102 can be avoided from deflection and peeling as much as possible, and the wind pressure resistance and insulation capacity of the building are improved.
[0026] An airtight layer 3 is also provided on the inner side of the autoclaved aerated concrete block 1 away from the insulation layer 102, and the airtight layer 3 is also provided above the floor slab 103. The airtight layer 3 is made of an airtight material such as airtight paint or concrete, so that the airtight layer 3 can effectively reduce the heat exchange between indoor and outdoor, and can reduce the heat transfer through the building envelope structure, thereby improving the thermal insulation and heat insulation performance of the building, helping to achieve the goal of ultra-low energy consumption buildings and improving building energy efficiency.
[0027] In addition, a corner guard line 4 and an alkali-resistant mesh cloth 5 are provided on the side of the thermal insulation layer 102 away from the autoclaved aerated concrete block 1, wherein the corner guard line 4 is provided at the corner of the thermal insulation layer 102 and is located on the inner side of the alkali-resistant mesh cloth 5 close to the autoclaved aerated concrete block 1. The corner guard line 4 can provide a certain protection to the corner of the thermal insulation layer 102, thereby ensuring the structural integrity of the thermal insulation layer 102 as much as possible.
[0028] The alkali-resistant mesh cloth 5 has the characteristics of high strength and alkali resistance, and is used to reduce the possibility of cracks on the insulation layer 102. In addition, by laying the alkali-resistant mesh cloth 5, the stress on the insulation layer 102 can be evenly dispersed, and the deformation of the entire insulation structure caused by the collision and extrusion of the external impact can be avoided, so that the insulation layer 102 has a high impact strength. Preferably, the two sides of the alkali-resistant mesh cloth 5 located on the same side of the building near the corner of the building extend vertically toward the insulation layer 102 of the adjacent exterior wall, so that a double-layer overlap structure is formed at the corner of the building insulation layer 102, ensuring the integrity and continuity of the alkali-resistant mesh cloth 5 laid on the insulation wall.
[0029] The implementation principle of a steel structure zero-energy building enclosure system in an embodiment of the present application is: by arranging autoclaved aerated concrete blocks 1 between the steel structure and the insulation layer 102, direct contact between the steel structure and the insulation layer 102 can be avoided, thereby blocking the thermal bridge effect at the steel structure as much as possible, so that the steel structure building meets the near-zero-energy building standards.
[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
