Description

Technical Field

[0001] This utility model relates to the field of steel pipe technology, specifically a bending-resistant special-shaped steel pipe. Background Technology

[0002] Special-shaped steel pipes refer to seamless or welded steel pipes with non-circular cross-sections. By optimizing the cross-section design, their mechanical properties are improved. The cross-section modulus of special-shaped pipes is larger than that of round pipes, and their bending strength is significantly improved. For example, the bending capacity of hexagonal pipes is much higher than that of round pipes of the same wall thickness.

[0003] Based on cross-sectional characteristics, they are mainly divided into the following three categories: equal wall thickness special-shaped tubes, characterized by uniform wall thickness throughout the cross-section, with cross-sectional shapes including square, rectangular, hexagonal, elliptical, etc.; unequal wall thickness special-shaped tubes, characterized by adjacent wall thickness differences ≥2mm and complex cross-sectional shapes; and variable diameter special-shaped tubes, characterized by gradual changes in diameter or wall thickness along the length direction, with cross-sectional shapes including conical, trapezoidal, spiral, etc.

[0004] In building structures, shaped steel pipes with uniform wall thickness are widely used. In practical applications, due to building height and shape issues, some parts of the steel pipe need to be reinforced to enhance its bending resistance. Existing technologies make it difficult to adjust and adapt shaped steel pipes according to the situation. Therefore, a bending-resistant shaped steel pipe is proposed to address the above problems.

Detailed Implementation

[0018] 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 scope of protection of the present utility model.

[0019] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail. This application discloses a bending-resistant special-shaped steel pipe. (Refer to...) Figure 1 , Figure 2 and Figure 3 A type of bending-resistant special-shaped steel pipe includes a special-shaped steel pipe 1, a reinforcing pipe 11 that slides in contact with the inner wall of the special-shaped steel pipe 1, a first threaded sleeve 12 that is fixedly connected to the side wall of the reinforcing pipe 11, a connecting rod 13 that is threadedly connected to the inner wall of the first threaded sleeve 12, a support plate 14 that is fixedly connected to the side wall of the reinforcing pipe 11, two pairs of springs 15 that are fixedly connected to the outer wall of the support plate 14, a top plate 16 that is fixedly connected to the outer wall of the springs 15, a rubber pad 19 that is fixedly connected to the outer wall of the top plate 16, a limit clip 17 that slides in contact with the inner wall of the top plate 16, a second threaded sleeve 18 that is fixedly connected to the side wall of the limit clip 17, and multiple connecting rods 13.

[0020] When using steel pipes, as needed, screw the connecting rod 13 into the first threaded sleeve 12, push the connecting rod 13 to slide the reinforcing tube 11 to the position that needs reinforcement, repeat the steps to thread the other connecting rod 13 into the second threaded sleeve 18, pull the second threaded sleeve 18 to slide the limit clip 17 out of the top plate 16, at this time the spring 15 will push the rubber pad 19 to contact the special-shaped steel pipe 1, increasing the friction between the rubber pad 19 and the special-shaped steel pipe 1, thereby restricting the movement of the reinforcing tube 11. At this time, the connecting rod 13 can be disengaged from the first threaded sleeve 12, and the reinforcing tube 11 will stay in the required position. Through the reinforcing tube 11 and the spring 15, the staff can make certain adjustments to the steel pipe according to the actual situation to increase the bending resistance of the steel pipe.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The limiting card 17 has a connecting plate 2 fixedly connected to its side wall, the connecting plate 2 has a connecting hole 21 on its side wall, and the connecting rod 13 has a hook 22 fixedly connected to its outer side wall.

[0022] The staff connects the hook 22 to the connection hole 21. At this time, pulling the hook 22 can also move the limit card 17. The hook 22 and the connection hole 21 make it easier for the staff to use the equipment and reduce the difficulty of using the equipment.

[0023] Reference Figure 2 , Figure 3 and Figure 4 A pair of limiting posts 3 are fixed to the inner side wall of the support plate 14. The limiting posts 3 are in contact with the top plate 16. The limiting posts 3 are located at the center of the spring 15. A pair of limiting strips 31 are fixed to the side wall of the support plate 14. The limiting strips 31 are in contact with the top plate 16 and the limiting strips 31 are in contact with the limiting card 17.

[0024] When the equipment is working, the limiting post 3 and the limiting strip 31 can restrict the direction of movement of the top plate 16 and the rubber pad 19. By setting the limiting post 3 and the limiting strip 31, the stability of the top plate 16 and the rubber pad 19 during movement is increased, and the failure rate of the equipment is reduced.

[0025] Reference Figure 1 The outer side wall of the connecting rod 13 is fixed with an anti-slip handle 4.

[0026] When the equipment is working, the anti-slip handle 4 can increase the friction between the operator's palm and the connecting rod 13. By setting the anti-slip handle 4, the probability of slippage when the operator rotates the connecting rod 13 is reduced.

[0027] Reference Figure 3 The connecting rod 13 has a scale groove 5 on its side wall.

[0028] When the equipment is working, the scale groove 5 can mark the length of the connecting rod 13. Through the scale groove 5, the operator can know the length of the connecting rod 13 that it extends into, and thus know the position of the reinforcing tube 11.

[0029] Reference Figure 1 The outer wall of the special-shaped steel pipe 1 is fixed with several reinforcing strips 6.

[0030] The reinforcing strip 6 can increase the overall bending strength of the special-shaped steel pipe 1. By setting the reinforcing strip 6, the overall bending resistance of the reinforcing pipe 11 is increased.

[0031] Reference Figure 2 , Figure 3 and Figure 4 The limiting strip 31 is made of a rigid material.

[0032] When the equipment is working, the limit bar 31 plays a certain limiting role. By setting the limit bar 31 to be made of rigid material, the possibility of the limit bar 31 bending and breaking during equipment operation is reduced, thereby increasing the stability of the equipment during operation.

[0033] Working Principle: When using the steel pipe, as needed, screw the connecting rod 13 into the first threaded sleeve 12, push the connecting rod 13 to slide the reinforcing tube 11 to the required position. Repeat the steps to connect the other connecting rod 13 to the second threaded sleeve 18. Pull the second threaded sleeve 18 to slide the limit card 17 out of the top plate 16. At this time, the spring 15 will push the rubber pad 19 to contact the shaped steel pipe 1, increasing the friction between the rubber pad 19 and the shaped steel pipe 1, thereby restricting the movement of the reinforcing tube 11. At this time, the connecting rod 13 can be disengaged from the first threaded sleeve 12, and the reinforcing tube 11 will stay in the required position. Through the reinforcing tube 11 and the spring 15, the operator can adjust the steel pipe according to the actual situation to increase the bending resistance of the steel pipe. The operator connects the hook 22 to the connecting hole 21. Pulling the hook 22 can also move the limit card 17. The hook 22 and the connecting hole 21 facilitate the operation of the equipment and reduce the operator's workload. The equipment is designed to be flexible and efficient. During operation, the limiting posts 3 and 31 restrict the movement of the top plate 16 and rubber pad 19, increasing stability and reducing the equipment's failure rate. The anti-slip handle 4 increases friction between the operator's hand and the connecting rod 13, reducing the probability of slippage when rotating the connecting rod 13. The scale groove 5 marks the length of the connecting rod 13, allowing the operator to determine its extension and the position of the reinforcing tube 11. The reinforcing strip 6 increases the overall bending resistance of the shaped steel pipe 11. The limiting strip 31 provides a limiting function; its rigid material reduces the risk of bending and breakage, increasing the equipment's stability.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
