Description

Technical Field

[0001] This utility model relates to the field of round steel pipe reinforcement, and more specifically, to a round steel pipe reinforcement welding positioning device. Background Technology

[0002] In existing building renovation projects, when the mechanical properties of round steel pipe components are insufficient due to long-term load or environmental influences, it is usually necessary to reinforce them with steel (such as steel pipe supports, gusset plates, etc.) by welding to improve their load-bearing capacity and stability. This reinforcement method is especially important for structural safety at joints or stress concentration areas.

[0003] However, existing circular steel pipes, as installed components, are fixed to the main structure at both ends, and their circular cross-section makes precise positioning of the reinforcing steel difficult when it is evenly positioned circumferentially. Furthermore, the limited space after the main structure is installed makes it difficult to properly install the circular steel pipes, and any temporary on-site fabrication has poor fit with the pipe, making it difficult to reuse and resulting in low utilization. Therefore, inventing a circular steel pipe reinforcement welding and positioning device to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0026] The device consists of a round steel pipe 3 to be reinforced and an irregularly shaped positioning plate 1. The irregularly shaped positioning plate 1 is arc-shaped, with an inner arc edge 14 on its inner wall. The inner arc edge 14 corresponds to and fits against the outer wall of the round steel pipe 3 to be reinforced. The irregularly shaped positioning plate 1 is distributed around the outside of the round steel pipe 3 to be reinforced. A reinforcing steel 4 is placed between the irregularly shaped positioning plate 1 and the round steel pipe 3 to be reinforced. One end of the reinforcing steel 4 is limited and engaged with the irregularly shaped positioning plate 1, and the other end of the reinforcing steel 4 is limited and abutted against the outer wall of the round steel pipe 3 to be reinforced. The device has a simple structure, is easy to install and disassemble, and the irregularly shaped positioning plate 1 can be reused, reducing construction costs. The outer arc edge 11 and the inner arc edge 14 are concentrically arranged, and the sliding groove edge 12 is concentric with the arc edge and can be connected by bolts 2 at any position. It is suitable for the reinforcement and positioning needs of round steel pipes of different specifications, and multiple sets of irregularly shaped positioning plates 1 can be combined to achieve flexible arrangement of multiple reinforcing steel 4.

[0027] Please see Figure 2 and Figure 3 Multiple sets of irregular positioning plates 1 are provided, and the multiple sets of irregular positioning plates 1 are distributed around the outer wall of the round steel pipe 3 to be reinforced. Two sets of multiple sets of irregular positioning plates 1 are symmetrically arranged, each set consisting of two plates. The two sets are also symmetrically arranged, and three plates can be arranged at the same time to form a ring around the round steel pipe 3 to be reinforced. At the same time, each irregular positioning plate 1 is staggered vertically for easy connection.

[0028] The outer wall of the irregular positioning plate 1 is provided with an outer arc edge 11, and the outer arc edge 11 and the inner arc edge 14 are concentrically arranged. A sliding groove edge 12 is opened on the side of the irregular positioning plate 1 near the outer arc edge 11. The sliding groove edge 12 is concentrically arranged with the outer arc edge 11 and the inner arc edge 14. One end of the sliding groove edge 12 passes through the outer arc edge 11. The end of the irregular positioning plate 1 through which the sliding groove edge 12 is passed is a rotating edge 15. The other end of the sliding groove edge 12 is located inside the irregular positioning plate 1, and bolts 2 can be connected at any position.

[0029] An embedded edge 13 is provided on the side of the irregular positioning plate 1 near the inner arc edge 14. The embedded edge 13 passes through one end of the irregular positioning plate 1 away from the sliding groove edge 12. A groove is provided at the protrusion of the embedded edge 13. The groove is engaged with the reinforcing steel 4 for limiting and locking. The reinforcing steel 4 is embedded in the groove of the embedded edge 13.

The bottom of the reinforcing steel 4 abuts against the outer wall of the round steel pipe 3 to be reinforced, and the top side of the reinforcing steel 4 is engaged with the embedded edge 13 for limiting and locking.

[0030] Multiple reinforcing steel members 4 are provided, corresponding to the irregular positioning plate 1 and the circular steel pipe 3 to be reinforced. Bolts 2 are installed inside the groove edge 12 of the two irregular positioning plates 1. The surface of the irregular positioning plate 1 is provided with trisecting angle positioning lines 16 and right angle positioning lines 17. The trisecting angle positioning lines 16 and right angle positioning lines 17 are respectively set on two sides of the irregular positioning plate 1.

[0031] Working principle: Positioning plate installation: Multiple (four or three) irregular positioning plates 1 are arranged around the outside of the round steel pipe 3 to be reinforced, so that the inner arc edge 14 is tightly fitted with the outer wall of the round steel pipe 3.

[0032] Angular positioning: Rotate the irregular positioning plate 1 around the circumference of the round steel pipe 3. According to the reinforcement requirements, align the rotating edge 15 of the irregular positioning plate 1 with the trisection positioning line 16 (used for trisection angle positioning, such as corresponding to each reinforcing steel 4) or the right angle positioning line 17 (used for right angle positioning, such as four reinforcing steel 4) on the other side of the irregular positioning plate 1 to achieve rapid and accurate positioning of the reinforcement angle.

[0033] Fixed connection: The relative positions of the two irregularly shaped positioning plates 1 are fixed by passing bolts 2 through the slide groove edge 12. The arc design of the slide groove edge 12 can be used to realize the bolt connection at any position, ensuring that the positioning plate and the round steel pipe 3 are tightly fixed.

[0034] Positioning of reinforcing steel: The top side of the T-shaped reinforcing steel 4 is embedded in the inner edge 13, and the bottom abuts against the outer wall of the round steel pipe 3. Through the limiting effect of the inner edge 13, the reinforcing steel 4 is accurately positioned in the circumference of the round steel pipe, and finally welded and fixed.
