Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically to a hyperbolic decorative strip installation system for large curved main steel structures. Background Technology

[0002] In recent years, with the rapid diversification of building exteriors, hyperbolic decorative strips have also been used on the roofs of various office buildings, giving them a rhythmic feel while also providing sun shading. Current technologies mostly employ fixed installation, where steel brackets are welded to the main steel structure using fillet welds, and the decorative strips are directly fixed to the main steel structure via welding or rigid connectors (such as angle brackets or bolts), without any adjustment margin. They also use a single support structure, such as directly fixing the decorative strip backing plate to the surface of the main steel beam with bolts, without reserving space for error compensation. Relying on a single column or beam for support, without setting up layered adjustment components, they cannot distribute or absorb the deformation stress of the main structure.

[0003] Therefore, the existing technology has the following drawbacks: 1. Poor adaptability to errors: The main steel structure is prone to bending, twisting or local deformation (such as warping caused by welding residual stress) during processing, transportation or installation. Traditional rigid connections cannot absorb such errors, resulting in unevenness and misalignment of joints after the decorative strips are installed, which seriously affects the appearance.

[0004] 2. Difficult to maintain and replace: The decorative strip is irreversibly fixed to the main structure. If local repair or replacement is required, a large area of ​​the surrounding structure must be removed, which is complicated and costly.

[0005] 3. Material stress concentration and insufficient durability: Rigid connections are prone to stress concentration between decorative strips and the main structure, which accelerates the fatigue deformation of aluminum alloy profiles or weld cracking. Utility Model Content

[0006] The purpose of this invention is to provide a hyperbolic decorative strip installation system for large curved main steel structures, in order to solve the problems of poor error adaptability, difficulty in maintenance and replacement, and insufficient material stress concentration and durability mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides a hyperbolic decorative strip installation system for large curved main steel structures, comprising: Vertical steel components are fixed to the main steel structure. The toothed aluminum alloy base has a T-shaped structure. An elongated hole is provided on the vertical part of the toothed aluminum alloy base, and a pig-nose bolt is installed in the elongated hole. The vertical part of the toothed aluminum alloy base is connected to the vertical steel workpiece through the pig-nose bolt. The aluminum alloy pressure block is connected to the lower vertical part of the toothed aluminum alloy base by stainless steel bolts. The first aluminum alloy U-channel is fixedly connected to the aluminum alloy pressure block. The second aluminum alloy U-channel is fixedly connected to the first aluminum alloy U-channel, and an aluminum alloy corner bracket is connected to the lower part of the second aluminum alloy U-channel. Single-curved aluminum back panel, connected to aluminum alloy corner brackets; The double-curved aluminum decorative strip is set on the outside of the second aluminum alloy U-groove and is fixedly connected to the second aluminum alloy U-groove.

[0008] In a preferred embodiment, a U-shaped groove is provided in the middle of the aluminum alloy pressure block, and the lower end of the vertical part of the toothed aluminum alloy base is set in the U-shaped groove of the aluminum alloy pressure block and connected to the fixing parts on both sides of the aluminum alloy pressure block by stainless steel bolts. The top of the fixing parts on both sides is used to fix the glass, and the bottom of the fixing parts on both sides is fixedly connected to the first aluminum alloy U-groove by stainless steel pan head screws.

[0009] In a preferred embodiment, the vertical portion of the toothed aluminum alloy base has serrated surfaces on both sides, and a toothed aluminum alloy washer is provided between the pig nose bolt and the vertical portion of the toothed aluminum alloy base. The toothed aluminum alloy washer has a serrated structure on the side near the toothed aluminum alloy base, and the serrated structure of the toothed aluminum alloy washer engages with the serrated surface of the toothed aluminum alloy base.

[0010] In a preferred embodiment, anti-corrosion rubber is installed between the vertical steel workpiece and the toothed aluminum alloy gasket, and rubber strips are provided between the horizontal part of the toothed aluminum alloy base and the glass, and between the aluminum alloy pressure block and the glass.

[0011] In a preferred embodiment, the hyperbolic aluminum decorative strip is made of a 3.5mm thick gradient perforated fluorocarbon-coated hyperbolic aluminum plate. The hyperbolic aluminum decorative strip is connected to a second aluminum alloy U-groove by countersunk screws, with the head of the countersunk screws being lower than the plate surface.

[0012] In a preferred embodiment, a 2mm thick rubber pad is provided between the first aluminum alloy U-groove and the bottom of the aluminum alloy pressure block.

[0013] In a preferred embodiment, the first aluminum alloy U-channel is a 114x50x6mm thick aluminum alloy U-channel, and the second aluminum alloy U-channel is a 134x100x6mm thick aluminum alloy U-channel.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Establishing a three-dimensional adjustable error compensation system: This utility model utilizes a toothed aluminum alloy base and an elongated hole design. The toothed aluminum alloy base has an elongated hole, which, combined with a pig-nose bolt and a toothed aluminum alloy washer, allows for horizontal and vertical adjustment. After adjustment, the toothed aluminum alloy washer secures the strip, ensuring that the finished surface accuracy of the hyperbolic aluminum decorative strip matches the theoretical value. This adapts to the processing errors and residual deformation of the main steel structure. The multi-layer modular connection structure, through the graded connection of the first aluminum alloy U-groove, the second aluminum alloy U-groove pressure block, and the aluminum alloy angle bracket, disperses stress and avoids the accumulation of localized deformation.

[0015] 2. Enhanced adaptability and durability: The vertical steel components are welded to the main steel structure to provide a stable foundation. Anti-corrosion rubber is installed between the vertical steel components and the toothed aluminum alloy base to isolate the steel from direct contact with the aluminum alloy and prevent electrochemical corrosion. Rubber pads are installed between the aluminum alloy pressure block and the toothed aluminum alloy base to buffer the hard contact between the glass and the metal, reduce vibration and noise, and achieve flexible adjustment.

[0016] 3. Easy to disassemble and assemble, partial component replacement, high construction efficiency, and reduced construction costs. Attached Figure Description

The steel component 1 is fixed to the main steel structure 11 and connected to the main steel structure 11 with a 10mm high fillet weld to provide a stable foundation. The components are arranged with a length of 50mm and a spacing of 300mm to ensure uniform stress and reduce the impact of local deformation of the main steel structure on the decorative strip.
