Description

Technical Field

[0001] This utility model relates to the field of purlin reinforcement technology for light steel plant roofs, and in particular to a special tiger clamp for purlin reinforcement. Background Technology

[0002] In existing building structures, purlins, as one of the main load-bearing components, are widely used in various timber, steel, and hybrid structures. Their main function is to bear the self-weight of the roof timber and static loads such as snow accumulation, and to transfer the load to the load-bearing walls or main beams through connection nodes. When reinforcing purlins, clamps are needed to increase their strength.

[0003] A purlin clamp secures the components on both sides of a purlin together to form a robust structure, preventing the purlin from bending or deforming under load. Its working principle is to increase the purlin's lateral stiffness and bending moment capacity. The clamp typically tightens around the purlin's ends or multiple key components, creating a tight fit with the purlin's supports or connections to ensure the load is evenly distributed and transferred to the load-bearing structure.

[0004] While traditional purlin clamps can reinforce purlins, insufficient contact area and friction during use can lead to uneven load-bearing capacity, causing slippage or misalignment. This reduces the stability and load-bearing capacity of the structure, affecting the overall reinforcement effect and safety. Therefore, a special purlin clamp for reinforcement is proposed to solve these problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a special tiger clamp for purlin reinforcement, which aims to improve the problem in the prior art that uneven load-bearing capacity can lead to slippage or misalignment, thereby reducing the stability and load-bearing capacity of the structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A special tiger clamp for purlin reinforcement includes a base, one end of which is fixedly connected to a support plate, and the other end of which is fixedly connected to a fixing block. The inner wall of the fixing block is threaded with a bolt, and the bolt is coupled to two purlin plates on the side of the support plate.

[0008] Specifically, during operation, the bolts transfer the force from the support plate to the purlin plates, ensuring that these two purlin plates can share the force generated by the upper load. Through the tight connection between the support plate and the fixing block, the entire reinforcement device effectively increases the load-bearing capacity of the purlins and reduces their deformation under load. By strengthening the connection between the purlin plates, the reinforcement device improves the stability of the structure, enabling the purlins to better resist external loads and achieve the reinforcement effect.

[0009] As a further description of the above technical solution:

[0010] One end of the bolt has a convex round head, and the support plate has a concave surface;

[0011] Specifically, one end of the bolt features a convex round head design, which effectively increases the contact area with the purlin plate, thus providing greater contact force. This design ensures that the bolt can distribute force more evenly when pressure is applied, reducing localized stress concentration and enhancing the stability of the connection. Simultaneously, the shape of the convex round head allows for stronger friction between the bolt and the purlin plate, ensuring that the connection will not loosen or slip under load. The support plate features a concave design, forming a tighter fit with the contact area between the bolt and the purlin plate. The concave shape allows the support plate to better adapt to the surface contour of the purlin plate, increasing the contact area and coefficient of friction. In this way, the support plate and purlin can effectively transfer the force from the upper load, resulting in a stronger bond between the purlin and the support plate, improving the reinforcement effect. Overall, this combination of convex round head and concave design helps enhance the load-bearing capacity and structural stability of the device, ensuring that the purlins can better share the load under external loads.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, the reinforcement device, through the design of convex round head bolts and concave support plates, increases the contact area and friction between the purlin and the support plate, ensuring that the newly added mid-span purlin and the original purlin can jointly bear the load. Surface treatment removes oil stains and loose rust, improves the roughness of the contact surface, and further enhances the coefficient of friction. These designs effectively improve the shear force transmission capacity between the two, prevent slippage or misalignment, enhance the stability and load-bearing capacity of the structure, and thus significantly improve the overall reinforcement effect and safety of use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1 to 3 This utility model provides an embodiment of a special tiger clamp for purlin reinforcement, including a base 1, a support plate 2 fixedly connected to one end of the base 1, a fixing block 3 fixedly connected to the other end of the support plate 2, a bolt 4 threadedly connected to the inner wall of the fixing block 3, and two purlin plates 5 coupled to the side of the support plate 2 near the bolt 4. One end of the bolt 4 has a convex round head, and the support plate 2 has a concave surface. This structure can effectively reinforce the purlin, and the stability of the reinforcement device is ensured by the fixed support of the base 1.

[0021] In practical applications, purlins often experience increased mid-span bending moments under additional loads, leading to increased deflection. Therefore, it is particularly important to take local reinforcement measures at locations with high stress. By setting up a structure with support plates 2 and fixing blocks 3, sufficient support can be provided when the purlin is subjected to external forces, preventing excessive deformation of the purlin and thus enhancing its load-bearing capacity.

[0022] To ensure that the newly added purlin and the existing purlin can share the load, the contact surface between them should be sufficiently supported by shear force. The bolt 4 of the clamp adopts a convex head design at one end, which can increase the contact area during installation and effectively enhance the friction between the bolt 4 and the purlin plate 5. The concave design of the support plate 2 can better fit with the purlin surface, increase the contact surface, achieve a stronger bonding force, and ensure that the original purlin and the newly added purlin can share the load.

[0023] During the connection process, in order to ensure a good coefficient of friction between the contact surfaces, the surfaces of the original purlin and the new purlin should be treated to remove oil stains and use a wire brush to remove surface rust. This treatment can effectively improve the coefficient of friction of the contact surfaces, enhance the connection strength between the two, and provide a strong guarantee for sharing the load.

[0024] Furthermore, by applying an appropriate torque, the bolt 4 and the support plate 2 are compressed and deformed, which in turn generates a large frictional force between the purlin plates 5. This frictional force can effectively resist the bending moment generated by the external load, enabling the purlins to more stably bear the load together, reduce structural deformation, and improve the stability and safety of the overall structure.

[0025] Working principle: Under stress, bolt 4 securely fixes purlin plate 5 to support plate 2 through threaded connection with the inner wall of fixing block 3. The convex head design of bolt 4 provides a larger contact area when in contact with purlin plate 5, which effectively increases the friction between the bolt and the surface of purlin plate 5, improves the stability of the connection, and ensures that purlin plate 5 can work together under external force, preventing slippage or loosening.

[0026] The concave design of the support plate 2 further enhances its fit with the purlin. Through precise alignment of the concave surface with the purlin surface, strong friction is generated between the support plate 2 and the purlin plate 5, thus achieving effective force transfer. This design ensures that the new purlin can share the load with the original purlin, reducing structural deformation and enhancing overall load-bearing capacity.

[0027] To ensure sufficient friction between the contact surfaces, the treatment of the bolt 4 connection area is crucial. During installation, oil stains on the purlin surface are removed, and loose rust is removed with a wire brush, increasing the roughness of the contact surface between the purlin and the support plate 2, thereby improving the coefficient of friction. The treated surface allows both to effectively share the load, preventing slippage or misalignment and ensuring structural stability.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
