Description

TECHNICAL FIELD

[0001] The application relates to the technical field of building envelopes, in particular to a steel structure near-zero-energy-consumption building envelope. BACKGROUND

[0002] Steel structures and prefabricated concrete wall panels gradually become the preferred solution in the field of modern buildings due to their high assembly rate and high degree of factory production characteristics. This structure not only significantly improves the construction efficiency, but also effectively reduces the on-site wet work, meeting the requirements of green buildings for energy saving, emission reduction and resource efficient utilization.

[0003] However, although the steel structure and the prefabricated concrete wall panel exhibit significant advantages in many aspects, there are still some problems to be solved in practical application: the heat preservation and fixation problem of steel beams and steel columns and the exposure problem. In traditional building design, the supporting components of the steel structure are often directly exposed to the outside, which not only affects the overall aesthetic appearance of the building, but also affects the overall heat preservation performance of the building, and even may cause rust and performance degradation of the steel due to long-term exposure to the natural environment, thereby affecting the structural safety and service life of the building. CONTENT OF THE UTILITY MODEL

[0007] By adopting the above technical scheme, the inner wall, the outer wall and the heat preservation layer are first connected and fixed in the factory by the connecting piece, the prefabricated outer wall panel is pre-made, and then the prefabricated outer wall panel is transferred to the site, so that the wrapping of the exposed steel column and the steel beam can be conveniently and quickly completed.

[0008] As a preferred, the connecting piece comprises a fixedly connected connecting plate, a first reinforcing plate and a second reinforcing plate, the connecting plate is arranged through the inner wall, the heat preservation layer and the outer wall in sequence; the first reinforcing plate and the second reinforcing plate are arranged at both ends of the connecting plate, and the first reinforcing plate is arranged in the inner wall, and the second reinforcing plate is arranged in the outer wall.

[0009] By adopting the technical scheme, the strength and stability of the connection between the inner wall, the thermal insulation layer and the outer wall are enhanced through the combined use of the connecting plate, the first reinforcing plate and the second reinforcing plate, thereby improving the load-bearing capacity of the wall body and helping to prolong the service life of the building.

[0010] Preferably, the plate surface of the first reinforcing plate and the plate surface of the second reinforcing plate are both perpendicular to the plate surface of the connecting plate, and the plate surface of the first reinforcing plate is parallel to the wall surface of the inner wall, and the plate surface of the second reinforcing plate is parallel to the wall surface of the outer wall.

[0012] Preferably, a splicing layer is arranged between two adjacent outer wall plates.

[0013] By adopting the technical scheme, the splicing layer can seal the joint between adjacent prefabricated outer wall plates, ensure the air tightness and water tightness of the enclosure structure, and further ensure the thermal insulation performance.

[0014] Preferably, the end of the splicing layer close to the outdoor and indoor is filled with sealant.

[0015] By adopting the technical scheme, the sealant can improve the sealing and waterproof effect of the joint of the prefabricated outer wall plate.

[0016] Preferably, the splicing layer includes a first splicing material arranged between two adjacent inner walls and two adjacent outer walls, and a second splicing material arranged between two adjacent thermal insulation layers, and the first splicing material and the second splicing material are tightly spliced.

[0017] By adopting the technical scheme, the different materials of the splicing materials are used to fill different positions of the joint between two adjacent outer wall plates, which can achieve better thermal insulation effect.

[0018] Preferably, the thermal conductivity of the second splicing material is less than that of the thermal insulation layer.

[0019] By adopting the technical scheme, the second splicing material with smaller thermal conductivity can improve the thermal insulation performance of the joint of the prefabricated outer wall plate.

[0020] Preferably, an outer veneer is installed on the side of the outer wall plate close to the outdoor.

[0024] Preferably, the inner wall of the splicing part of the outer wall panel and the steel beam and the steel column is provided with a mounting port.

[0025] By adopting the above technical scheme, by reserving the mounting port in advance when the outer wall panel is prefabricated, the thermal insulation layer of the outer wall panel can be directly used as the thermal insulation layer of the steel beam and the steel column when the outer wall panel is spliced with the steel beam and the steel column, thereby solving the thermal insulation and fixing problem of the beam and column part; and in combination with the smaller beam and column specifications, the thickness after the fireproof coating is completed is ensured to be flush with the inner wall, thereby solving the problem of indoor exposed beam and column.

[0028] 2. By setting the splicing layer and filling the sealant at both ends of the splicing layer, the overall sealing performance of the building envelope structure is improved;

[0029] 3. By setting the second splicing material, the thermal insulation performance at the splicing part of the prefabricated outer wall panel is improved. BRIEF DESCRIPTION OF DRAWINGS

In the embodiment, the connecting piece 4 is arranged as an I-beam, and the connecting piece 4 is integrated in the inner part between the inner wall 1, the outer wall 3 and the intermediate thermal insulation layer 2 during factory production, so that the connecting strength of the inner wall 1, the outer wall 3 and the thermal insulation layer 2 can be improved.

[0037] The prefabricated outer wall panel is spliced with another prefabricated outer wall panel on the side close to the steel beam 101 and the steel column 100, and a splicing layer 5 is arranged at the splicing position between two adjacent prefabricated outer wall panels. Specifically, the splicing layer 5 is arranged between two adjacent prefabricated outer wall panels.
