Description

Technical Field

[0001] This application relates to the field of building exterior wall insulation construction technology, and in particular to a steel frame exterior wall insulation system structure. Background Technology

[0002] Steel structures, as a form of high-rise building structure, are widely used in the construction industry due to their high strength, light weight, good ductility, seismic resistance, and short construction period, especially in super high-rise and large-span buildings, demonstrating their strong vitality. External wall insulation systems, as an important building energy-saving technology, are widely used in engineering practice.

[0003] However, in recent years, accidents involving the detachment of external wall insulation systems have occurred frequently, causing adverse effects on society. The construction quality of external wall insulation systems for steel structure residential buildings is more susceptible to damage than that of external wall insulation systems for ordinary concrete structures. According to traditional construction methods, the external wall insulation rock wool boards are easily detached when the steel beams and columns are fixed by adhesive mortar, posing a safety hazard. Ordinary rock wool steel rivets cannot be driven into the steel columns and beams. Therefore, an improvement has been made to the structure of a steel frame external wall insulation system. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a steel frame external wall insulation system structure that overcomes the deficiencies of existing technologies. It aims to solve the problems in traditional construction methods where the external wall insulation rock wool board is easily detached and poses a safety hazard due to the reliance on adhesive mortar to fix the steel beams and columns, and the inability of ordinary rock wool steel rivets to be driven into the steel columns and beams.

[0005] To achieve the above objectives, this application provides the following technical solution: a steel frame external wall insulation system structure, including a wall, a steel frame embedded in the front side of the wall, an external wall insulation structure provided on the front side of the steel frame, the external wall insulation structure being composed of a plurality of external wall insulation panels, a plurality of positioning members uniformly distributed in a linear array fixedly welded to the outer surface of the steel frame, the positioning members being located inside the external wall insulation panels, the positioning members having a hollow cylindrical structure and having connecting threads inside, a plurality of expansion joints uniformly distributed in a circumferential array being opened near the upper end of the outer wall of the positioning members, the positioning members being threadedly connected to fixing members through connecting threads, and the external wall insulation panels being located between the steel frame and the fixing members.

[0006] By adopting the above technical solution, the external wall insulation board is fixedly installed onto the steel frame through the cooperation between the positioning component, connecting thread, and fixing component. By setting an expansion joint on the outer wall of the positioning component, during the process of tightening the fixing component to insert it into the positioning component, the fixing component will squeeze the positioning component outward to abut against the external wall insulation board, thereby increasing the tightness of the connection between the positioning component and the external wall insulation board, ensuring that the external wall insulation board will not fall off after installation through this structure, and guaranteeing safety.

[0007] As a preferred technical solution of this application, the fastener includes a threaded connection part and a pressing part. The threaded connection part matches the connecting thread, and the pressing part is tapered in shape with its outer wall abutting against the inner wall of the positioning part.

[0008] By adopting the above technical solution, it is ensured that the positioning part can be squeezed through the extrusion part during the tightening of the fastener, so that the positioning part can be opened.

[0009] As a preferred technical solution of this application, the number of positioning members and fixing members are the same and they correspond one-to-one.

[0010] By adopting the above technical solutions, the precise positioning of the external wall insulation board during the installation process can be effectively guaranteed, ensuring the stability of the installation.

[0011] As a preferred technical solution of this application, the outer surface of the external wall insulation board is provided with a placement groove, and a connector is provided inside the rectangular groove formed by two adjacent placement grooves. The connector is fixedly connected to the external wall insulation board by fixing bolts.

[0012] By adopting the above technical solution, the connection between the connectors and the fixing bolts can be used to combine two adjacent exterior wall insulation boards into a whole, thereby ensuring good connection and connectivity between the exterior wall insulation boards, and evenly dispersing the detachment force, making it less likely for the exterior wall insulation boards to fall off.

[0013] As a preferred technical solution of this application, a number of expansion bolts are fixedly installed inside the steel frame, and the steel frame is fixedly connected to the wall through the expansion bolts.

[0014] By adopting the above technical solution, the steel frame is fixedly installed on the wall using expansion bolts.

[0015] As a preferred technical solution of this application, the external wall insulation board includes a waterproof layer, a rock wool insulation board is fixedly connected to the front side of the waterproof layer, a double layer of alkali-resistant fiberglass mesh is fixedly connected to the front side of the rock wool insulation board, and a plastering mortar is applied to the front side of the double layer of alkali-resistant fiberglass mesh.

[0016] By adopting the above technical solution, and by setting up a waterproof layer, rock wool insulation board and double-layer alkali-resistant fiberglass mesh, the external wall insulation board has excellent waterproof, heat insulation and impact resistance capabilities. The flatness of the external wall insulation board is ensured by setting up a plastering mortar.

[0017] As a preferred technical solution of this application, the outer surface of the external wall insulation board is coated with real stone paint, which is made of green and environmentally friendly materials.

[0018] By adopting the above technical solutions, real stone paint, as the outer surface coating of exterior wall insulation boards, is not only aesthetically pleasing, but also provides excellent waterproof and weather-resistant properties.

[0019] The beneficial effects of this application are:

[0020] In this invention, a steel frame is fixed to the wall using expansion bolts. The external wall insulation board is then fixed to the steel frame using the cooperation of positioning components, connecting threads, and fixing components. An expansion joint is provided on the outer wall of the positioning component. During the tightening of the fixing component, the positioning component is compressed by the fixing component, causing it to open outwards and abut against the external wall insulation board. This increases the tightness of the connection between the positioning component and the external wall insulation board, ensuring that the external wall insulation board will not fall off after installation, thus guaranteeing safety. The cooperation between the connecting components and fixing bolts allows adjacent external wall insulation boards to be combined into a single unit, ensuring good connection and connectivity between the various external wall insulation boards and evenly distributing the detachment force, making it less likely for the external wall insulation board to fall off.
