Description

Technical Field

[0001] This utility model belongs to the field of precast reinforced concrete pipe manufacturing, specifically relating to a precast reinforced concrete pipe reinforcement binding formwork. Background Technology

[0002] In the production process of precast reinforced concrete pipes, the fabrication of the reinforcing steel cage is a crucial step. The reinforcing steel cage provides the main load-bearing capacity and structural stability of the concrete, and its binding quality directly affects the overall quality and load-bearing capacity of the precast concrete pipe.

[0003] The rebar tying formwork currently used in construction consists of a support frame, a connecting shaft, and two tying discs. After the rebar skeleton is tied, the connecting shaft needs to be pulled out from the support frame and the two tying discs. Then, the rebar skeleton and the two tying discs are lowered to the ground. After that, the rebar skeleton is pushed out of the support frame, and the two tying discs are removed one by one. This operation method is time-consuming, labor-intensive, and inefficient.

[0004] Therefore, corresponding improvements should be made to address the shortcomings of existing rebar tying formwork. Utility Model Content

[0005] To address the problems of complex operation, time-consuming and labor-intensive rebar tying formwork currently used in construction, this utility model provides a precast reinforced concrete pipe rebar tying formwork.

[0006] The solution adopted by this utility model to solve its technical problem is: a precast reinforced concrete pipe rebar binding formwork, including a drive assembly, a lifting unit, two parallel bottom beams and two symmetrically arranged triangular frames. The upper part of the triangular frames is rotatably mounted with a support shaft, and the end of the support shaft is fitted with a binding disc. The edge of the binding disc is surrounded by multiple rebar holes.

[0007] Both ends of the bottom beam are provided with connecting beams. The connecting beams can slide along the inner cavity of the bottom beam, and their outer ends are fixedly connected to the tripod. The drive assembly is installed between the two bottom beams and can drive the tripods on both sides to move away from or closer to each other.

[0008] The lifting unit includes two parallel crossbeams, with multiple support seats fixedly installed between the two crossbeams. Two hydraulic rods are fixedly installed on the top of the crossbeams, and the piston rods of the hydraulic rods pass through the crossbeams and are fixedly installed with fixing blocks. The fixing blocks are welded and fixed to the side of the bottom beam.

[0009] Preferably, the bottom of the tripod has a groove, and multiple casters are fixedly installed in the groove.

[0010] Preferably, the drive assembly includes two mounting plates and two cylinders. The mounting plates are fixedly installed between two bottom beams, and the cylinders are fixedly installed on the side of the mounting plates, with their piston rods passing through the mounting plates and fixedly connected to the tripod.

[0011] Preferably, the top of the support base has an arc-shaped cavity for supporting the steel reinforcement skeleton.

[0012] Preferably, the bottom beam, connecting beam, and crossbeam are made of square or rectangular tubing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model controls the synchronous extension of four hydraulic rods to move three support seats upwards, supporting the bottom of the steel reinforcement cage. By controlling the synchronous extension of two cylinders, the triangular frames on both sides are moved away from each other, separating the binding plate from the steel reinforcement cage. This facilitates the connection of the lifting equipment hook to the steel reinforcement cage, allowing the steel reinforcement cage to be lifted to the designated position. This eliminates the need for complex manual disassembly operations, significantly shortens the demolding time of the steel reinforcement cage, and greatly saves labor and time costs.

[0015] 2. By incorporating connecting beams and casters, this utility model makes the tripod more flexible to move while maintaining sufficient stability. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1-2 This utility model provides a technical solution for a precast reinforced concrete pipe rebar tying formwork:

[0021] Example 1:

[0022] according to Figure 1 and Figure 2As shown, it includes a drive assembly, a lifting unit, two parallel bottom beams 1 and two symmetrically arranged triangular frames 41. The upper part of the triangular frames 41 is equipped with a bearing, and a support shaft 42 is installed inside the bearing. The end of the support shaft 42 is fitted with a binding disc 43. The edge of the binding disc 43 is surrounded by multiple rebar holes 44, so that the rebars can be inserted into the rebar holes 44 to facilitate binding of the rebar skeleton.

[0023] Connecting beams 2 are provided in the openings at both ends of the bottom beam 1. The connecting beams 2 can slide along the inner cavity of the bottom beam 1, and their outer ends are fixedly connected to the tripod 41. The drive assembly includes two mounting plates 31 and two cylinders 32. The mounting plates 31 are fixedly installed between the two bottom beams 1, and the cylinders 32 are fixedly installed on the side of the mounting plates 31. Their piston rods pass through the mounting plates 31 and are fixedly connected to the tripod 41. By controlling the synchronous extension and retraction of the two cylinders 32, the tripods 41 on both sides are driven to move away from or closer to each other. Under the action of the connecting beams 2, the stability of the tripod 41 during movement can be improved.

[0024] The lifting unit includes two parallel crossbeams 51, with multiple support seats 52 fixedly installed between the two crossbeams 51. The top of each support seat 52 has an arc-shaped cavity for supporting the steel reinforcement cage. The arc-shaped cavity has a large contact area with the steel reinforcement cage, ensuring the stability of the steel reinforcement cage. Two hydraulic rods 53 are fixedly installed on the top of the crossbeams 51. The piston rods of the hydraulic rods 53 pass through the crossbeams 51 and are fixedly installed with a fixing block 54. The fixing block 54 is welded and fixed to the side of the bottom beam 1. By controlling the synchronous extension and retraction of the four hydraulic rods 53, the two crossbeams 51 and the three support seats 52 can move upward or downward.

[0025] The bottom beam 1, connecting beam 2, and cross beam 51 are all made of square and rectangular tubes.

[0026] In practical use, the precast reinforced concrete pipe rebar binding formwork of this utility model first inserts the rebars one by one into the rebar holes 44, and uses the binding discs 43 on both sides to support the rebars.

[0027] After the longitudinal main bars and circumferential stirrups are tied and fixed with wire to form a steel reinforcement cage, the synchronous extension of the four hydraulic rods 53 is controlled to move the three support seats 52 upward to support the bottom of the steel reinforcement cage. Then, the synchronous extension of the two cylinders 32 is controlled to move the triangular frames 41 on both sides away from each other, so that the binding plate 43 is separated from the steel reinforcement cage. Finally, the hook of the lifting equipment is connected to the steel reinforcement cage, and the steel reinforcement cage is lifted to the designated position.

[0028] Example 2:

[0029] Based on Example 1, such as Figure 2As shown, the bottom of the tripod 41 has a groove, and multiple casters 45 are fixedly installed in the groove. The casters 45 provide auxiliary support for the tripod 41, making the tripod 41 more flexible when moving, while maintaining sufficient stability.
