Description

Technical Field

[0001] This utility model belongs to the field of steel pipe technology, and in particular relates to a special-shaped cross-section steel pipe with internal reinforcement. Background Technology

[0002] Unlike conventional round or square steel pipes, irregularly shaped steel pipes have irregular cross-sections, such as elliptical, T-shaped, or polygonal, such as P-shaped steel pipes. They are widely used in fields such as building steel structures and energy transmission pipelines.

[0003] Because irregularly shaped steel pipes have multi-sided bending properties, precise alignment of each point is required before welding adjacent irregularly shaped steel pipes. However, irregularly shaped steel pipes do not have a natural centering structure inside, and there is no axis reference during the alignment process. The alignment and welding process requires repeated adjustments using external tooling, which is troublesome and has low positioning accuracy. Since a suitable connection structure is not integrated inside the steel pipe, it is impossible to achieve both precise alignment and welding convenience at the same time, which restricts its application in high-precision and high-efficiency welding scenarios.

[0004] In view of this, we propose a special-shaped steel pipe with internal reinforcement. Utility Model Content

[0005] The purpose of this utility model is to provide a special-shaped cross-section steel pipe with internal reinforcement to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a special-shaped cross-section steel pipe with internal reinforcement, including a P-shaped steel pipe, wherein a first reinforcing plate and a second reinforcing plate are fixedly installed on the inner wall of the P-shaped steel pipe, a first support rod is fixedly installed on the inner wall of the first reinforcing plate, and a second support rod is fixedly installed on the inner wall of the second reinforcing plate. A fixing ring is fixedly installed at one end of the support rod one and the support rod two. A connecting pipe is fixedly installed on the inner wall of the fixing ring, and a positioning rod is slidably connected to the inner wall of the connecting pipe. The connecting pipe has a connecting groove inside, and a connecting plate is slidably connected to the inner wall of the connecting groove.

[0007] In this technical solution, reinforcing plates one and two can be used to fix and support one end of support rod one and support rod two. At this time, one end of support rod one and support rod two is supported by reinforcing plates one and two to support the inside of the steel pipe. When connecting adjacent special-shaped steel pipes, the positioning rod is inserted into the inside of the connecting pipe. At this time, the connecting plate enters the inside of the connecting groove. The positioning rod and the connecting rod limit the positioning and connection of adjacent P-shaped steel pipes.

[0008] In the above technical solution, the first reinforcing plate and the second reinforcing plate are both located at the inner corner of the P-shaped steel pipe, and the first support rod and the second support rod are arranged in a ring array outside the fixing ring.

[0009] In this technical solution, both reinforcing plate one and reinforcing plate two are steel structures, and are set at multiple internal corners to support support rod one and support rod two.

[0010] In the above technical solution, furthermore, a reinforcing plate three is fixedly installed on the inner wall of the P-shaped steel pipe, and the outer surface of a set of support rods two is fixedly installed on the outer surface of the reinforcing plate three. The reinforcing plate three is located inside the P-shaped steel pipe near the middle position.

[0011] In this technical solution, the reinforcing plate three is set at the bend of the P-shaped steel, which can connect one end of a set of support rods two, and together with the other support rods one and two, form a support structure.

[0012] In the above technical solution, further, a support rod three is fixedly installed on the inner wall of the reinforcing plate three, and the outer surface of the support rod three is fixedly installed on the inner wall of the P-shaped steel pipe.

[0013] In this technical solution, the support rod three and the reinforcing plate three form a structure that supports the bending position of the P-shaped steel pipe, and the tensile strength and auxiliary support of the support rod three are used to increase the structural stability of the bending position.

[0014] In the above technical solution, furthermore, each set of fixed rings is provided with positioning rings on both sides, and the outer surface of the connecting pipe is fixedly installed with the inner wall of the positioning ring.

[0015] In this technical solution, adjacent positioning rings limit the fixed rings, and each set of fixed rings is positioned by two sets of fixedly installed positioning rings.

[0016] In the above technical solution, further, baffles are fixedly installed at equal intervals on the inner wall of the connecting pipe, and one end of the positioning rod is in contact with one side of the baffle.

[0017] In this technical solution, multiple sets of baffles can limit one end of the positioning rod, and the baffles can create multiple limiting positions inside the connecting tube.

[0018] In the above technical solution, the outer surface of the connecting plate is fixedly installed with the outer surface of the positioning rod, and the connecting plate is arranged in a ring around the outside of the positioning rod.

[0019] In this technical solution, the positioning rod and the connecting plate can position the connecting pipe and provide a docking point for the connection of adjacent P-shaped steel pipes.

[0020] The beneficial effects of this utility model are: 1. This irregularly shaped steel pipe with internal reinforcement, through the cooperation between the connecting pipe and the positioning rod, connects the adjacent positioning rod and the connecting pipe when adjacent P-shaped steel pipes are butted together. At this time, the connecting plate is aligned with the corresponding connecting groove. The positioning rod and the connecting plate can quickly position the pipe, that is, it can quickly connect adjacent pipes during welding, without having to repeatedly observe and adjust the position during the connection. This realizes the function of quick connection during the welding of irregularly shaped steel pipes, which helps to reduce the inconvenience of repeated adjustments during the connection.

[0021] 2. This irregularly shaped steel pipe with internal reinforcement, by setting up support rod one and support rod two and other components, can increase the deformation resistance of the steel pipe by utilizing the cross structure formed by support rod one and support rod two. Multiple sets of support rod one and support rod two are evenly spaced inside the P-shaped steel pipe, which can provide stable support for the steel pipe at multiple positions.

[0026] Example 1: This example provides a special-shaped cross-section steel pipe with internal reinforcement, including a P-shaped steel pipe 1. The inner wall of the P-shaped steel pipe 1 is fixedly installed with a first reinforcing plate 2 and a second reinforcing plate 3. The inner wall of the first reinforcing plate 2 is fixedly installed with a first support rod 4, and the inner wall of the second reinforcing plate 3 is fixedly installed with a second support rod 5. A fixing ring 6 is fixedly installed at one end of support rod 1 4 and support rod 2 5. A connecting pipe 7 is fixedly installed on the inner wall of the fixing ring 6. A positioning rod 8 is slidably connected to the inner wall of the connecting pipe 7. The connecting pipe 7 has a connecting groove 9 inside, and a connecting plate 10 is slidably connected to the inner wall of the connecting groove 9.

[0027] Among them, the first reinforcing plate 2 and the second reinforcing plate 3 can fix and support one end of the first supporting rod 4 and the second supporting rod 5. At this time, the first end of the first supporting rod 4 and the second supporting rod 5 uses the first reinforcing plate 2 and the second reinforcing plate 3 to support the inside of the steel pipe. When connecting adjacent special-shaped steel pipes, the positioning rod 8 is inserted into the inside of the connecting pipe 7. At this time, the connecting plate 10 enters the inside of the connecting groove 9. The positioning rod 8 and the limiting of the connecting rod can be used to position and connect the adjacent P-shaped steel pipes 1. Support rod 4 and support rod 5 together with the fixing ring 6 form a support structure, which can form a cross structure inside the P-shaped steel pipe 1. Support rod 4 and support rod 5 are arranged at equal intervals inside the P-shaped steel pipe 1, which can form support at multiple points and improve the stability of the P-shaped steel pipe 1 under multi-position compression and bending.

[0028] Example 2: This example provides a steel pipe with an irregular cross section reinforced with internal ribs. In addition to the technical solution of the above example, it also has the following technical features: the reinforcing plate 1 2 and the reinforcing plate 2 3 are both set at the inner corner of the P-shaped steel pipe 1, and the support rod 1 4 and the support rod 2 5 are arranged in a ring array outside the fixing ring 6.

[0029] Among them, reinforcing plate 12 and reinforcing plate 23 are both steel structures, which are set at multiple internal corners to support support rod 14 and support rod 25, and the internal support effect is improved by using a ring-shaped cross structure.

[0030] Example 3: This example provides a steel pipe with an irregular cross section reinforced with internal ribs. In addition to the technical solution of the above example, it also has the following technical features: a reinforcing plate 311 is fixedly installed on the inner wall of the P-shaped steel pipe 1, and the outer surface of a set of support rods 25 is fixedly installed with the outer surface of the reinforcing plate 311. The reinforcing plate 311 is located inside the P-shaped steel pipe 1 near the middle position.

[0031] Among them, the reinforcing plate 311 is set at the bend of the P-shaped steel, which can connect one end of a set of support rods 25, and form a support structure with the other support rods 14 and support rods 25.

[0032] Example 4: This example provides a special-shaped cross-section steel pipe with internal reinforcement. In addition to the technical solutions of the above examples, it also has the following technical features: a support rod 12 is fixedly installed on the inner wall of the reinforcing plate 11, and the outer surface of the support rod 12 is fixedly installed on the inner wall of the P-shaped steel pipe 1.

[0033] Among them, the support rod 312 and the reinforcing plate 311 form a structure that supports the bending position of the P-shaped steel pipe 1, and the tensile strength and auxiliary support of the support rod 312 are used to increase the structural stability of the bending position.

[0034] Example 5: This example provides a special-shaped cross-section steel pipe with internal reinforcement. In addition to the technical solutions of the above examples, it also has the following technical features: each set of fixing rings 6 is provided with positioning rings 13 on both sides, and the outer surface of the connecting pipe 7 is fixedly installed with the inner wall of the positioning rings 13.

[0035] The adjacent positioning rings 13 limit the fixed rings 6. Each set of fixed rings 6 is positioned by two sets of fixedly installed positioning rings 13, which can provide auxiliary support for one end of the support rod 4 and the support rod 5, and further increase the support force.

[0036] Example 6: This example provides a steel pipe with an irregular cross section reinforced with internal ribs. In addition to the technical solutions of the above examples, it also has the following technical features: baffles 14 are fixedly installed at equal intervals on the inner wall of the connecting pipe 7, and one end of the positioning rod 8 is in contact with one side of the baffle 14.

[0037] Among them, multiple sets of baffles 14 can limit one end of the positioning rod 8. Different lengths of connecting pipe 7 can be customized according to different sizes of steel pipe. The baffles 14 can make multiple sets of limiting positions inside the connecting pipe 7 to prevent the positioning rod 8 from moving through after the inside of the connecting pipe 7 is connected.

[0038] Example 7: This example provides a steel pipe with an irregular cross-section reinforced with internal ribs. In addition to the technical solutions of the above examples, it also has the following technical features: the outer surface of the connecting plate 10 is fixedly installed with the outer surface of the positioning rod 8, and the connecting plate 10 is arranged in a ring around the outside of the positioning rod 8.

[0039] The positioning rod 8 and the connecting plate 10 can position the connecting pipe 7 and provide a docking point for connecting adjacent P-shaped steel pipes 1. Thus, when docking adjacent P-shaped steel pipes 1, it is only necessary to dock the connecting plate 10 and the positioning rod 8. At the same time, the installed positioning rod 8, together with the connecting pipe 7, can also provide auxiliary support for the interior of the P-shaped steel pipe 1.

[0040] Working principle: The first reinforcing plate 2 and the second reinforcing plate 3 can position one end of the first supporting rod 4 and the second supporting rod 5. The third reinforcing plate 11 and the third supporting rod 12 provide auxiliary support for the bending position of the P-shaped steel pipe 1. At this time, multiple sets of first supporting rod 4 and second supporting rod 5, together with the fixing ring 6, form a cross support mechanism, which can improve the support stability of multiple positions inside the P-shaped steel pipe 1. When connecting adjacent P-shaped steel pipes 1, the positioning rod 8 is inserted into the inside of the connecting pipe 7, and the adjacent connecting plate 10 is inserted into the inside of the connecting groove 9. The positioning rod 8 and the P-shaped steel pipe 1 are limited by the limiting effect of multiple sets of connecting plates 10 and connecting groove 9. At this time, the adjacent P-shaped steel pipes 1 are accurately connected under the action of the positioning rod 8 and the connecting pipe 7.
