Description

Technical Field

[0001] This utility model relates to the field of wind-resistant connection technology, and in particular to a wind-resistant fixing device for color steel panels on steel structure roofs. Background Technology

[0002] Traditional wind-resistant fixing devices deform the steel plates at the joints after prolonged clamping, reducing the lateral length of the joint. The fixing bolts cannot self-tighten. Although the lower diamond-shaped structure, when lifted by wind at the joint, compresses the clamping plates on both sides, increasing the angle between them and tightening the joint again, the gaps created by the steel plate deformation are not eliminated. When there is no wind lifting force, the steel plate naturally descends, and the clamping plates, losing their compression, loosen again. This causes the diamond-shaped structure at the joint to repeatedly bounce up and down when the roof encounters a pulsed upwind, forcing the clamping plates on both sides to vibrate and impact the joint, exacerbating its deformation. This vicious cycle quickly leads to the fixing structure losing its fixing ability. Therefore, this invention improves upon existing equipment to address these problems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wind-resistant fixing device for color steel panels on steel roofs.

[0005] Preferably, the lower assembly includes a fixed plate, the lower end of which is fixedly connected to the top surface of the connecting plate, and a rotating plate is provided on one side of the fixed plate. The fixed plate and the rotating plate are engaged together by a set of protrusions that abut against each other.

[0006] Preferably, the fixed plate and the rotating plate are provided with a first vertical opening at both the front and rear, and the upper surfaces of the fixed plate and the rotating plate are provided with a first oblique joint surface.

[0007] Preferably, the upper connecting component includes a claw plate, which abuts against the opposite sides of the fixed connecting plate and the rotating connecting plate. The claw plate has a second horizontal opening, a second oblique connecting surface is formed on the opposite lower surface of the claw plate, and a diamond-shaped clamping surface is formed on the inner side of the upper part of the claw plate.

[0008] Preferably, the connecting component includes a conical block, the lower end of which has a third horizontal opening, and the lower ends of both sides of the conical block have inclined surfaces that abut against the first inclined surface.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model eliminates the phenomenon of the two clamping plates colliding with the steel plate connection caused by the pulse-type updraft in the existing structure, through the cooperation of the lower connecting component, the upper connecting component, and the connecting component. Instead, it transforms the impact into a change in the overall length of the device. This only causes wear on the conical structure, and the wear resistance of the conical structure is undoubtedly stronger than the impact resistance of the steel plate structure, which greatly increases the lifespan of the device. Secondly, the friction process of the conical structure plays a certain damping role, which can also reduce the vibration of the steel plate, thereby greatly improving the wind resistance of the device. Finally, it solves the problem of short service life of the existing fixed structure. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4 The steel structure roof color steel plate anti-wind-shear fixing device of this utility model includes a connecting plate 1. The connecting plate 1 has installation slots on both sides. A lower connecting component is fixed to the top surface of the connecting plate 1. An upper connecting component is abutted against the outside of the lower connecting component. A connecting component is provided between the lower connecting component and the upper connecting component. The lower connecting component and the upper connecting component are slidably connected together through the connecting component.

[0015] In this utility model, to solve the problem of short service life of existing fixing structures, the following technical solution is adopted: The lower connecting component includes a fixed connecting plate 2, the lower end of which is fixedly connected to the top surface of the connecting plate 1. A rotating connecting plate 3 is provided on one side of the fixed connecting plate 2. The fixed connecting plate 2 and the rotating connecting plate 3 are connected together by a set of protrusions that abut against each other. The fixed connecting plate 2 and the rotating connecting plate 3 are provided with first vertical openings 4 at both the front and rear. The upper facing surfaces of the fixed connecting plate 2 and the rotating connecting plate 3 are provided with first oblique contact surfaces 5. The upper connecting component includes a claw plate 6, which abuts against the opposite surfaces of the fixed connecting plate 2 and the rotating connecting plate 3. The claw plate 6 is provided with a second horizontal opening 7, and the lower facing surfaces of the claw plate 6 are provided with a second oblique contact surface 8. A diamond-shaped clamping surface 9 is provided on the inner side of the upper part of the claw plate 6. The connecting component includes a conical block 10, the lower end of which is provided with a third horizontal opening 1. 1. The lower ends of both sides of the conical block 10 are provided with inclined surfaces, which abut against the first inclined surface 5. The third horizontal opening 11, the second horizontal opening 7 and the first vertical opening 4 are aligned and a threaded rod 13 passes through them. One end of the threaded rod 13 is fixed with a fixing nut 12, and the outer side of the other end of the threaded rod 13 is screwed with a movable nut 14. Through the cooperation of the lower connecting component, the upper connecting component and the connecting component, the phenomenon of the two clamping plates vibrating and impacting the steel plate connection caused by the pulse-type upward wind force in the existing structure is eliminated and converted into the overall length change of the device. This will only wear the conical structure, and the wear resistance of the conical structure is undoubtedly stronger than the impact resistance of the steel plate structure, which greatly increases the service life of the device. Secondly, the friction process of the conical structure plays a certain damping role, which can also reduce the vibration of the steel plate, thereby greatly improving the wind resistance of the device.

[0016] Working principle: When using this utility model, firstly, the clamping surface 9 on the claw plate 6 abuts against the steel plate connection. Then, the protrusion below the rotating connecting plate 3 abuts against the protrusion of the fixed connecting plate 2. Next, the conical block 10 is attached to the first oblique connecting surface 5. Then, the second oblique connecting surface 8 at the lower end of the claw plate 6 abuts against the back surfaces of the fixed connecting plate 2 and the rotating connecting plate 3. Finally, the threaded rod 13 is passed through the through hole formed by aligning the first oblique opening 4, the second horizontal opening 7, and the third horizontal opening 11. Then, the movable nut 14 is screwed onto the threaded rod 13 and tightened. At this time, the first oblique connecting surface... The inclined surfaces of face 5 and cone block 10 clamp and rub against each other, and the second inclined contact surface 8 clamps and rubs against the back surfaces of fixed contact plate 2 and rotating contact plate 3. Because the lower end of the device is jammed and the clamping surface 9 of the upper claw plate 6 is also limited by the steel plate connection, a threaded rod 13 is used to limit the included angle of the device. Therefore, the device can effectively fasten and support the steel plate. Finally, the connecting plate 1 is installed and fixed on the roof beam to complete the installation. When the steel plate connection deforms and shrinks due to compression, the contact surface at the upper end of the claw plate 6 loses its limit, thereby reducing the included angle of the claw plate 6. This causes the second oblique joint surface 8 to lose clamping force and friction. Under its own weight, the claw plate 6 descends, which in turn causes the conical block 10 to descend, thus compressing the first oblique joint surface 5. This increases the angle between the fixed joint plate 2 and the rotating joint plate 3, filling the gap between the fixed nut 12, the moving nut 14, and the claw plate 6 caused by deformation and contraction due to compression at the steel plate joint, and restoring the fixed support. When the steel plate is lifted by wind, the steel plate joint will cause the claw plate 6 to rise, thus driving it through the threaded rod 13. As the conical block 10 rises, the first inclined surface 5 slides on the inclined surface of the conical block 10, while the second inclined surface 8 slides on the opposite sides of the fixed plate 2 and the rotating plate 3. The rhomboid clamping surfaces 9 move away from each other under the pressure at the steel plate connection, thus increasing the included angle of the claw plates 6. This fills the gap between the fixed nut 12, the movable nut 14 and the claw plates 6 again. In summary, when facing high-frequency pulsed wind lifting, the entire device is always tightly attached to each other, thus avoiding collisions caused by gaps and extending the service life of the device.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
