Description

Technical Field

[0001] This utility model relates to the field of steel structure exterior wall panel technology, and in particular to a weather-resistant steel structure exterior wall panel connection structure. Background Technology

[0002] Weather-resistant steel structure exterior wall panel connection structures are mainly used in the construction of exterior walls for various buildings, especially in projects with complex outdoor environments and high requirements for the durability of building exterior walls, such as industrial plants, high-rise buildings, and coastal buildings. Their function is to firmly connect the exterior wall panels to the steel structure, while their excellent weather resistance protects against the erosion of natural factors such as wind, sun, rain, and temperature changes, ensuring the stability and integrity of the building's exterior wall structure and extending the building's service life. Currently, weather-resistant steel structure exterior wall panel connection structures typically require the following technologies in practical applications:

[0003] 1. Reliable connection technology: Ensures a stable connection between the exterior wall panels and the steel structure, withstands various loads such as the weight of the exterior wall panels themselves, wind force, and seismic force, and ensures that the connection parts do not loosen or fall off during long-term use;

[0004] 2. Weather-resistant material selection technology: Select appropriate weather-resistant materials for the connection structure to ensure that it can maintain stable performance under different climatic conditions and prevent the connection structure from failing due to material corrosion, aging, etc.

[0005] 3. Easy installation technology: The designed connection structure should facilitate construction and installation, reduce construction difficulty and cost, and improve construction efficiency.

[0006] Currently, various equipment and methods are used to achieve the connection function of weather-resistant steel structure exterior wall panels. Some also employ bolted connections, using bolts and nuts to connect the steel structure and exterior wall panels through pre-drilled bolt holes; this method is relatively convenient for installation.

[0007] However, the above method has a prominent problem. To facilitate installation and positioning, existing exterior wall panels usually have a raised positioning block at the top, which, together with the groove at the bottom, facilitates the stacking of multiple exterior wall panels. However, the groove of the first exterior wall panel at the bottom usually lacks elastic filling effect. Over a long period of use, due to factors such as wind, temperature, and ground settlement, the gap at the connection point will gradually increase, leading to a decrease in the overall structural stability of the exterior wall panel and affecting its service life and structural safety.

The arc-shaped anti-loosening block 16 fits against the outer surface of the guide rail 13. The U-shaped mounting base 12 is fixed to the inner end surface of the main steel frame 11 by tightening bolts. The guide rail 13 is installed on the inner surface of the U-shaped mounting base 12, and a rubber sleeve is fitted onto the surface of the guide rail 13. The rubber filling pad 14 can be attached to the inner wall of the groove 28 of the outer wall panel body 25. Due to the high strength of the rubber filling pad 14, it can buffer the structural deformation caused by temperature changes, wind force, etc. to a certain extent, and avoid the weak points caused by gaps in the groove 28 of the outer wall panel. The placement position of the arc-shaped clamping block 16 can be adjusted by turning the adjusting bolt rod 15, and the arc-shaped clamping block 16 can clamp and limit the rubber filling pad 14.

[0032] To address the problems existing in the prior art, this utility model provides a weather-resistant steel structure exterior wall panel connection structure. A U-shaped mounting base 12 is installed and fixed inside the main steel frame 11 via screw-on bolts.

Tightening the adjusting bolt rod 15 moves the arc-shaped abutment block 16, adjusting its position to tighten and limit the rubber filling pad 14, maintaining its buffering function and tight fit with the exterior wall panel. Utilizing the elasticity of the high-strength rubber material of the rubber filling pad 14, it buffers structural deformation caused by temperature changes and wind force, preventing the exterior wall panel groove 28 from becoming a weak point due to gaps, and preventing damage to the exterior wall panel due to stress concentration caused by deformation.

[0033] Working principle:

[0034] The first step involves fixing a steel frame 23 to one side of the main steel frame 11. An insulation base plate 24 is then fixed to the outer surface of the steel frame 23. The exterior wall panel body 25 is located at the upper end of the insulation base plate 24 and fixed to the outer surface of the steel frame 23. The steel frame 23 is made of weathering steel (Corten steel), which can form a dense oxide protective film in the atmospheric environment, slowing down the corrosion of the steel. Before installing the exterior wall panel body 25, the insulation base plate 24 is first installed on the lower end of the surface of the steel frame 23 by nailing self-tapping screws 26 into it with a hand drill. Multiple exterior wall panel bodies 25 are installed sequentially from bottom to top. Self-tapping screws 26 are screwed into the protrusions 27 of each exterior wall panel body 25 for fixation. When installing the second exterior wall panel body 25, the lower end of the exterior wall panel groove 28 is aligned with the surface of the protrusions 27 of the next exterior wall panel to achieve rapid positioning and installation.

[0035] In the second step, the U-shaped mounting base 12 is fixed inside the main steel frame 11 by screwing bolts. The inner surface of the U-shaped mounting base 12 is fixed with a guide rail 13, and the outer surface of the guide rail 13 is fitted with a rubber filling pad 14. When the outer wall panel body 25 is installed, the rubber filling pad 14 fits against the inner wall of the outer wall panel groove 28 inside the outer wall panel body 25. The elasticity of the high-strength rubber material of the rubber filling pad 14 buffers the structural deformation caused by temperature changes, wind force, etc., and prevents the outer wall panel groove 28 from becoming a weak point due to gaps, thus preventing the outer wall panel from being damaged by stress concentration due to deformation. The abutment mechanism inside the U-shaped mounting base 12 consists of an adjusting bolt rod 15 and an arc-shaped abutment block 16. The adjusting bolt rod 15 is threaded into the U-shaped mounting base 12, and the arc-shaped abutment block 16 is fixed to the outer surface of the adjusting bolt rod 15 and fits against the outer surface of the guide rail 13. Tightening the adjusting bolt rod 15 moves the arc-shaped abutment block 16. Adjust its position to tighten and limit the rubber filling pad 14, preventing it from loosening or shifting due to vibration, deformation, or other factors, maintaining its buffering function and tight fit with the exterior wall panel. Fix the nut 17 to the outer surface of the U-shaped mounting base 12. The nut 17 is internally threaded with two additional screws 18. The additional screws 18 are threaded to the outer surface of the U-shaped base 19. The adjusting bolt rod 15 passes through the U-shaped base 19. Before installing the first exterior wall panel body 25 at the bottom, screw the additional screws 18 to install them inside the nut 17 to fix the U-shaped base 19. The reinforcing screw 21 inside the U-shaped base 19 increases the structural stability. Fix the positioning block 22 to the side of the U-shaped base 19 near the guide rail 13. The positioning block 22 is similar in shape to the protrusion 27 of the exterior wall panel. When installing the first exterior wall panel body 25, the positioning block 22 cooperates with the groove 28 of the exterior wall panel at the bottom of the exterior wall panel body 25 to achieve a quick positioning effect.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
