Description

Technical Field

[0001] The utility model relates to the technical field of wind-resistant clamps, in particular to a wind-resistant clamp for a complex and special-shaped non-continuous steel structure roof. Background Art

[0002] With the widespread application of metal enclosure system roofs in building roofs such as airports, railway stations, large exhibition halls, and cultural and art centers, the wind resistance of roof panels is becoming more and more important in the face of various natural disasters such as typhoons. The existing vertical lock seam system cannot meet the wind resistance requirements of roofs in coastal areas, especially for non-continuous vertical lock seam structures. Due to the short bite edges of some parts, the wind resistance is reduced, affecting the normal use of the roof.

[0003] In this regard, a search by a new information search agency revealed that announcement number CN216921033U discloses a complex and special-shaped non-continuous steel structure roof wind-resistant clamp, which fixes two roof panels with fixed supports, the fixed support comprising a base, a connecting rod and a plum blossom head, the plum blossom head is fixedly connected to the base through the connecting rod, the edges of the two roof panels overlap and are fixed at the position of the plum blossom head by snapping, the complex and special-shaped non-continuous steel structure roof wind-resistant clamp comprises a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate are connected by a connecting piece, the edges of the two roof panels are arranged between the first clamping plate and the second clamping plate, the connecting piece is arranged as a connecting bolt and a connecting nut; the edges of the roof panels are reinforced by the complex and special-shaped non-continuous steel structure roof wind-resistant clamp so that the roof panels and the fixed supports fit tightly to improve the overall wind resistance of the roof.

[0004] The above technology discloses a complex and special-shaped non-continuous steel structure roof wind-resistant clamp, which is achieved by bending the connection of two roof panels to fit on the outside of the plum blossom head, using bolts and connecting nuts to tighten the connection between the first clamping plate and the second clamping plate, and using the arc-shaped clamping part on the clamping plate to clamp the connection of the two roof panels fitted on the outside of the plum blossom head, and using the overlap of clamping and bending to achieve wind-resistant effect, but there are still the following shortcomings when using it: 1. The two clamping plates are disassembled and assembled by bolts and connecting nuts, and the integrity is not good. The disassembly and assembly method is prone to have many scattered parts, which may cause the loss of a part and poor convenience of use; 2. When fixing, there is a lack of a stable and tightened structure for the lower part of the upward bent part of the roof panel. Since the lower part of the clamping plate is open and long, it is easy to cause unstable clamping at the lower position. In strong winds, the part of the roof panel that is bent upward may vibrate and collide, and the stability in use is not ideal; in view of this, the application proposes a complex and special-shaped non-continuous steel structure roof wind-resistant clamp to solve the above problems.

[0026] A telescopic bidirectional threaded drive assembly is rotatably installed in the rectangular tube 1, and two L-shaped moving rods 2 are sleeved on the telescopic bidirectional threaded drive assembly. The telescopic bidirectional threaded drive assembly is used to drive two arc-shaped clamping blocks 3 to move close to or repel each other through the two L-shaped moving rods 2. When the two arc-shaped clamping blocks 3 move close to each other, the two roof panels 100 wrapped around the outside of the cylindrical structure 102 are pressed and fixed. The two sides of the two roof panels 100 are wrapped and fixed in an arc shape, so that the connection parts of the two roof panels 100 can be effectively overlapped. Closed clamping prevents wind from entering from the splicing parts and causing the roof panel 100 connection to be blown and lifted, thereby achieving a wind-resistant effect; the bottom of the adjacent side of the two arc-shaped clamping blocks 3 are embedded and fixed with elastic telescopic tensioning components, and the upward bending parts of the two roof panels 100 are located between the two elastic telescopic tensioning components.

[0028] Furthermore, the elastic telescopic tensioning component includes an outer tube 9, and the two outer tubes 9 are respectively embedded and fixed at the bottom of one side close to the two arc-shaped clamping blocks 3, wherein the bottom of the one side close to the two arc-shaped clamping blocks 3 are provided with embedding holes respectively fixedly connected to the outer sides of the corresponding outer tubes 9, and the repelling ends of the two outer tubes 9 are set as blocking structures, and the inner sleeve of the outer tube 9 is provided with an inner rod 10, and the ends of the two inner rods 10 close to each other are fixedly connected with a pressure block 12, and a spring 11 is fixedly connected between the end of the inner rod 10 away from the corresponding pressure block 12 and the inner wall of the end of the corresponding outer tube 9 away from the pressure block 12, and the sides of the two pressure blocks 12 are bonded and fixed with anti-slip rubber 8; the outer tube 9, spring 11, inner rod 10 and pressure block 12 are arranged to cooperate, and the two outer tubes 9 are driven to move close to each other when the two arc-shaped clamping blocks 3 move close to each other, and the two outer tubes 9 pass through in turn. The two springs 11 and the two inner rods 10 drive the two pressure blocks 12 to squeeze the upward bending parts of the two roof panels 100 toward the middle. In the squeezed state, the two outer tubes 9 that continue to move close to each other compress the two springs 11. The elastic force of the springs 11 is utilized to achieve the effect of elastically tightening and clamping the upward bending parts of the two roof panels 100 toward the middle by the two pressure blocks 12, thereby preventing the upward bending parts from continuously swinging and colliding due to wind.

The two roof panels 100 are clamped after being wrapped in an arc shape on one side thereof, so that the connection parts of the two roof panels 100 can be overlapped, closed and clamped effectively, thereby preventing the wind from entering from the splicing parts and causing the connection parts of the roof panels 100 to be blown and lifted, thereby achieving a wind-resistant effect. In addition, the wind-resistant clamp body is integrally arranged, and the two arc-shaped clamping blocks 3 can be synchronously moved close to or repelled from each other, thereby improving the integrity of the wind-resistant clamp body, without the need for disassembly and assembly, so that the wind-resistant clamp body does not have scattered parts, thereby avoiding the phenomenon of loss of a certain part, and the operation is simple, thereby improving the convenience of use.

[0030] When the two arc-shaped clamping blocks 3 move close to each other, they also drive the two outer tubes 9 to move close to each other. The two outer tubes 9 drive the two pressure blocks 12 to move close to each other through the two springs 11 and the two inner rods 10 in turn. The two pressure blocks 12 drive the two anti-slip rubbers 8 to squeeze the upward bending parts of the two roof panels 100 toward the middle. In the squeezed state, the two outer tubes 9 that continue to move close to each other compress the two springs 11.
