Description

Technical Field

[0001] The present invention relates to the technical field of column pier formwork reinforcement, and specifically relates to an adjustable column pier formwork reinforcement device for large and small columns. Background Art

[0002] During the casting process of column pier formwork at the construction site, additional reinforcement is required. For special-shaped column pier structures, additional formwork erection and reinforcement are required before casting. Moreover, traditional reinforcement methods are prone to phenomena such as slurry leakage and grout leakage, resulting in cost waste and affecting the quality of the project's finished products. It is necessary to add a cable tie reinforcement device to make the casting of column pier formwork more firm, ensure the construction quality, and facilitate the reinforcement of special-shaped column pier structures.

[0003] A Chinese patent with the publication number CN218618102U discloses a metal cable tie, which includes a metal strip. A groove is provided on the metal strip, and a plurality of protruding teeth are fixedly connected to the inner bottom wall of the groove. The right top end of the metal strip is fixedly connected with a card box. Openings are provided at both the left and right ends of the card box, and sliding grooves are provided on the inner walls of both the left and right sides of the card box. Sliding blocks are slidably connected inside the sliding grooves, and connecting plates are fixedly connected to the opposite sides of the two sliding blocks.

[0004] Through the cooperation of the metal strip, protruding teeth, limit teeth, springs, etc., the above patent facilitates the formation of a bundling loop of a required size when the metal strip is bent into a ring. Through the cooperation of the pull ring, pull plate, stabilizing rod, spring, etc., it is convenient to pull the limit teeth upward to disengage the limit teeth from the protruding teeth, so as to facilitate people to extract the metal strip in the card box. The structure is simple and convenient, facilitating quick disassembly, and can be reused, with high practicability.

[0005] However, the above patent has the following deficiencies: During the reinforcement process of special-shaped column pier structures, there is a situation where a single cable tie cannot bundle the column pier structure, and multiple cable ties need to be spliced. During the splicing process, the connection position between the cable ties is the weakest and is prone to falling off, resulting in unstable connection, thus affecting the reinforcement of the column pier structure. During the reinforcement process, there is a phenomenon of overly long cable ties. Since the cable ties made of galvanized iron sheet are relatively sharp and it is not convenient to cut off the overly long cable ties, there are potential safety hazards.

[0006] Therefore, the present invention provides an adjustable column pier formwork reinforcement device with stable connection and convenient storage of overly long cable ties. Summary of the Invention

[0011] Further, the tying mouth is a square tying mouth, the materials of the tying mouth and the tying belt are galvanized iron sheets, and the clamping grooves are arranged at equal distances on the clamping groove belt in a linear distribution.

[0012] Further, two limiting grooves adapted to the connecting blocks are symmetrically opened at the end of the tying belt.

[0013] Further, the positioning component includes a threaded block fixedly installed on the two connecting blocks, and a first screw is threadedly installed on the threaded block.

[0014] Further, a positioning hole adapted to the first screw is opened on the tying belt.

[0035] In this embodiment, an anti-slip mechanism is provided on the tie mouth 1. The anti-slip mechanism includes a fixed frame 6 fixedly installed on the tie mouth 1. A plurality of torsion springs 7 are connected to the fixed frame 6. The end of each torsion spring 7 is connected to a buckle 8 rotatably connected to the fixed frame 6. A toothed cylinder 9 is fixedly installed between every two buckles 8. A plurality of serrated blades 5 adapted to the toothed cylinder 9 are fixedly installed on the tie strap 3. A positioning mechanism is provided on the fixed frame 6. The positioning mechanism includes a pair of connecting blocks 11 symmetrically and fixedly installed on the fixed frame 6. A positioning component is fixedly installed on the pair of connecting blocks 11. Two limiting grooves 10 adapted to the connecting blocks 11 are symmetrically formed at the end of the tie strap 3. The positioning component includes a threaded block 12 fixedly installed on the two connecting blocks 11. A first screw 13 is threadedly installed on the threaded block 12.
