Description

Technical Field

[0001] This utility model belongs to the field of tire frame technology, specifically relating to a positioning tire frame. Background Technology

[0002] Prestressed concrete structures are playing an increasingly important role in bridge construction, especially in large and heavy bridges. However, in cast-in-place box girder structures that are prone to short spans and small turning radii, prestressed concrete cannot be used. Therefore, cast-in-place box girders are necessary, with steel reinforcement cages tied to a formwork, which is both standardized and efficient.

[0003] Generally, steel reinforcement cages are tied to the frame with steel wires. The process of tying the steel wires to the frame involves folding the wires in half and wrapping them around the connection points of the frame, which requires a certain number of turns and involves multiple nodes that need to be operated one by one, making the operation quite cumbersome.

The double beam positioning components 3 include a first U-shaped connecting rod 31 and a second U-shaped connecting rod 32. The precast box girder bottom web plate jig 1 has a first side beam 11 and a second side beam 12. The first U-shaped connecting rod 31 is located outside the first side beam 11, and the connecting steel bar 2 is located inside the first U-shaped connecting rod 31 to form a positioning point. The second U-shaped connecting rod 32 is located outside the first side beam 11 to connect to the first U-shaped connecting rod 31.

[0021] In this embodiment: the double-beam positioning assembly 3 includes a first U-shaped connecting rod 31 and a second U-shaped connecting rod 32. The precast box girder bottom web frame 1 has a first side beam 11 and a second side beam 12. The first U-shaped connecting rod 31 is located outside the first side beam 11, and the connecting steel bar 2 is located inside the first U-shaped connecting rod 31 to form a positioning point. The second U-shaped connecting rod 32 is located outside the first side beam 11 and connects to the first U-shaped connecting rod 31. When the second U-shaped connecting rod 32 is connected to the first U-shaped connecting rod 31, the second U-shaped connecting rod 32 and the first U-shaped connecting rod 31 are located outside the first side beam 11 and the second side beam 12, respectively, so that the second U-shaped connecting rod 32... The first U-shaped connecting rod 31, when combined with the first U-shaped connecting rod 32, enhances the strength of the frame. The first U-shaped connecting rod 31 can restrict the connection of the steel reinforcement 2 and pass through the insertion sleeve 33, and is fixed with the locking nut 34. At this time, the first U-shaped connecting rod 31 can hold the outside of the second side beam 12, and the second U-shaped connecting rod 32 can hold the outside of the first side beam 11. The positioning of the connection of the steel reinforcement 2 is achieved by the mutual holding of the first U-shaped connecting rod 31 and the second U-shaped connecting rod 32. The combination of the first U-shaped connecting rod 31 and the second U-shaped connecting rod 32 is located outside the precast box girder bottom web frame 1, which not only facilitates positioning and connection, but also enhances the overall strength.

[0022] The first U-shaped connecting rod 31 and the second U-shaped connecting rod 32 are located outside the first side beam 11. The first U-shaped connecting rod 31 and the second U-shaped connecting rod 32 have an included angle. The first U-shaped connecting rod 31 and the second U-shaped connecting rod 32 are connected to each other and have an included angle, which can be 100 to 130 degrees. After the first U-shaped connecting rod 31 and the second U-shaped connecting rod 32 are fixed, they are not prone to slippage due to the tilting effect of the two sides, thus improving the stability of the positioning.

[0023] Two threaded rods 311 are fixedly connected to the outer end of the first U-shaped connecting rod 31. Locking nuts 34 are threaded onto the outer wall of the threaded rods 311. Insertion sleeves 33 are fixedly connected to both ends of the second U-shaped connecting rod 32. The two insertion sleeves 33 pass through the two ends of the first U-shaped connecting rod 31 respectively. The first U-shaped connecting rod 31 can restrict the connecting steel bar 2 and allow the first U-shaped connecting rod 31 to pass through the insertion sleeves 33 and be fixed with locking nuts 34.

[0024] The insertion sleeve 33 has a connecting hole 331, and the first U-shaped connecting rod 31 is located in the connecting hole 331. When the first U-shaped connecting rod 31 is connected in the connecting hole 331, the first U-shaped connecting rod 31 and the second U-shaped connecting rod 32 can be easily connected to each other.

[0025] The outer wall of the second U-shaped connecting rod 32 contacts the outer side of the precast box girder bottom web frame 1, and the outer wall of the first U-shaped connecting rod 31 contacts the outer side of the connecting steel bar 2; the first U-shaped connecting rod 31 is located outside the first side beam 11, and the connecting steel bar 2 is located inside the first U-shaped connecting rod 31, forming a positioning point.

[0026] The working principle and usage process of this utility model: The second U-shaped connecting rod 32 is located outside the first side beam 11 and connects to the first U-shaped connecting rod 31. When the second U-shaped connecting rod 32 is connected to the first U-shaped connecting rod 31, the second U-shaped connecting rod 32 and the first U-shaped connecting rod 31 are located outside the first side beam 11 and the second side beam 12 respectively. This allows the second U-shaped connecting rod 32 and the first U-shaped connecting rod 31 to be combined as a whole, improving the strength of the frame. The first U-shaped connecting rod 31 can restrict the connecting steel bar 2 and make the first U-shaped connecting rod 31... The U-shaped connecting rod 31 passes through the insertion sleeve 33 and is fixed with the locking nut 34. At this time, the first U-shaped connecting rod 31 can be tightly held on the outside of the second side beam 12, and the second U-shaped connecting rod 32 can be tightly held on the outside of the first side beam 11. The positioning of the connecting steel bar 2 is achieved by the mutual clamping of the first U-shaped connecting rod 31 and the second U-shaped connecting rod 32. The combination of the first U-shaped connecting rod 31 and the second U-shaped connecting rod 32 is located outside the precast box girder bottom web frame 1, which not only facilitates positioning and connection, but also enhances the overall strength.
