Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a triangular inner support device for recyclable pile foundation steel reinforcement cages. Background Technique

[0002] During the construction of bridge foundations and lower structures, etc., in order to ensure that the steel reinforcement cage does not deform during hoisting and installation, the existing methods mainly include:

[0003] Welding several equilateral triangle steel bar supports longitudinally at intervals along the cage body inside the steel reinforcement cage to increase the overall stiffness, but there are the following problems:

[0004] 1. There is a large waste of steel bar materials. The triangular steel bar supports use steel bars with the same diameter as the main bars of the steel reinforcement cage. The function of the triangular steel bar supports is to ensure that the cage body does not deform during the hoisting of the steel bars. They are not the designed permanent structural steel bars. If the support steel bars are not removed during the installation of the steel reinforcement cage, the steel bar loss is large.

[0005] 2. There is a large safety risk. Even if the support steel bars are removed during the installation of the steel reinforcement cage, in order to protect the mechanical properties of the steel bars, the cold cutting process is used. Due to the small spacing between the main bars of the steel reinforcement cage, the operation space is limited and the safety risk is large; and after each removal, each support steel bar is worn by about 15 cm and the length becomes shorter, so it cannot be recycled.

[0006] Therefore, the utility model provides a triangular inner support device for recyclable pile foundation steel reinforcement cages to solve the above problems. Content of the Utility Model

[0015] Preferably, a plug is fixedly installed on the front surface of the intermediate plate, the plug is inserted into the corresponding combined plate, and each combined plate is inserted with a plug and a bolt rod.

[0016] With the above technical solution, the stability of the combined plate is ensured by the plug and the bolt rod.

[0019] Beneficial effects

[0020] The utility model provides a triangular inner support device for a pile foundation steel reinforcement cage that can be recycled. Compared with the prior art, it has the following beneficial effects:

[0021] 1.

The outward support force supports the inner reinforcing ring. During disassembly, reverse-rotate the inner threaded ring to reduce the force applied by the lead screw to the clamping plate, and the support component can be disassembled from the inside of the inner reinforcing ring, thus realizing that when supporting the steel reinforcement cage, the overall detachability can be ensured, greatly reducing the use cost.

[0022] 2. For the triangular inner support device for the pile foundation steel reinforcement cage that can be recycled, by screwing the nut onto the outer side of the bolt rod, the combined plate and the intermediate plate are fixed. After fixation, the stability of the fixed combined plate can be ensured by the plug and it will not rotate easily, thus realizing the overall detachability of the support component, greatly improving the portability when the support component is reused.
