Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a clamping plate for fixing a curtain wall channel steel connector and an H-shaped steel structure. Background Art

[0002] Steel-framed construction is a new building system. Compared to traditional concrete construction, steel plates or steel sections replace reinforced concrete, resulting in higher strength and improved earthquake resistance. Furthermore, because components can be factory-fabricated and installed on-site, construction time is significantly reduced. The reusability of steel significantly reduces construction waste, making it more environmentally friendly. Currently, the application of steel-framed construction in high-rise and super-high-rise buildings is becoming increasingly mature, gradually becoming a mainstream construction technology, widely used in industrial and residential buildings.

[0003] A glass curtain wall refers to a building's exterior protective structure or decorative structure that has a supporting structural system that allows a certain degree of displacement relative to the main structure and does not share the forces acting on the main structure. Common load-bearing beams in steel structure buildings are H-shaped steel. The exterior curtain wall of a steel structure building will use steel keels as the outer frame, with embedded aluminum window frames to install glass. However, since the beams and columns of the main structure are all H-shaped steel structures, the stress-bearing rooting points of the exterior curtain wall cannot be fixed to reinforced concrete using conventional embedded parts or expansion bolts. Directly welding the curtain wall keels to the H-shaped steel structure will, on the one hand, result in high operating intensity and an unsightly molding effect, and on the other hand, damage the integrity of the H-shaped steel structure, reducing the service life of the main steel structure. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a splint for fixing a curtain wall channel steel connector and an H-shaped steel structure, which is convenient for assembly and fixation and avoids direct welding.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is a splint for fixing a curtain wall channel steel connector to an H-shaped steel structure, comprising two sets of fixing clips and a connector;

[0006] The fixing clamp includes a first clamping plate, a second clamping plate and a fixing plate, wherein the first clamping plate and the second clamping plate are arranged in parallel and fixedly connected to one side of the fixing plate, and a clamping groove is formed between the first clamping plate and the second clamping plate;

[0007] Two sets of fixing clamps are respectively clamped on the front and rear sides of the H-shaped steel structure. The H-shaped steel structure includes two sets of upper and lower flange plates and web plates. The first clamping plate and the second clamping plate are respectively clamped on the upper and lower sides of the flange plates. The end of the flange plate away from the web plate is located in the clamping groove.

[0008] A connecting piece is connected between the fixing plates of the two sets of fixing clamps, and the connecting piece can adjust the distance between the two fixing plates.

[0009] The beneficial effect of the above technical solution is that the fixing clamps can be clamped on the flange plate of the H-shaped steel structure. After the front and rear sets of fixing clamps are fastened and connected by the connecting pieces, an integrated and stable installation base can be formed on the H-shaped steel structure, and then the curtain wall channel steel connecting piece is fixed on the installation base. On the one hand, the operation is convenient during curtain wall construction, and when the curtain wall channel steel connecting piece takes root on the H-shaped steel structure, it can ensure that the connection between the channel steel and the H-shaped steel structure is tighter. On the other hand, the entire connection method does not destroy the structure of the H-shaped steel structure itself, thereby increasing the safety of curtain wall construction.

[0010] Furthermore, the groove width of the clamping groove is the same as the thickness of the flange plate of the H-shaped steel structure.

[0011] Beneficial effect: If the width of the clip groove is too small, the flange plate cannot be inserted; if the width of the clip groove is too large, gaps will appear, resulting in unstable force on the fixing clamp. Ensuring that the flange plate and the clip groove are adapted and connected can ensure that the fixing clamp is clamped tightly and stably.

[0012] Furthermore, the cross section of the fixing clamp is F-shaped, the end of the first clamping plate is fixedly connected to the end of the fixing plate, and the first clamping plate is clamped on the side of the flange plate close to the web plate.

[0013] Beneficial effect: Providing the installation position of the connector, ensuring that after the fixing clips are clamped on both sides of the H-shaped steel structure flange plate, there is space to connect and fix the two sets of fixing clips from the outside of the H-shaped steel structure, avoiding damaging the integrity of the H-shaped steel structure web structure.

[0014] Furthermore, reinforcing ribs are provided between the second clamping plate and the fixing plate.

[0015] Beneficial effect: prevents the fixing plate from being pulled and deformed after the fixing clip is subjected to force.

[0016] Furthermore, two sets of reinforcing ribs are provided on each fixing clip, and the two sets of reinforcing ribs are respectively located at the left and right ends of the fixing plate.

[0017] Beneficial effect: Ensure that the fixing plate is supported and reinforced by the reinforcement ribs as a whole, further ensuring the stability of the fixing plate structure.

[0018] Furthermore, the connecting member is a tension bolt, a through hole is provided on the fixing plate, and the tension bolt connects the two sets of fixing clamps through the through hole.

[0019] Beneficial effect: The fixing clamps on the front and rear sides of the H-shaped steel structure can be tightened by the tension bolts, thereby providing a stable installation foundation for the curtain wall channel steel connector.

[0020] Furthermore, the through hole is provided on a side of the fixing plate away from the web.

[0021] Beneficial effect: The through holes corresponding to the tension bolts are located on the outside of the H-shaped steel structure away from the web, and do not need to pass through the web, thereby protecting the integrity of the H-shaped steel structure. BRIEF DESCRIPTION OF THE DRAWINGS
