Description

Technical Field

[0001] The utility model relates to a template fixing structure, in particular to a fixing structure for a concrete wall casting template. Background Art

[0002] In construction engineering, the casting of concrete walls is a crucial construction link, and its quality directly affects the stability and durability of the entire building structure. During the casting process of concrete walls, the fixing and supporting structure of the template plays a vital role. In order to ensure that the quality of the wall can firmly support the stability and durability of the entire building structure, the stable fixing and efficient supporting technology of the template has become a key technical point.

[0003] Traditional template fixing methods mostly use materials such as wooden squares and steel pipes for support and fixing, which have disadvantages such as insecure fixing and easy deformation. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems existing in the existing template fixing methods, such as insecure fixing and easy deformation, and to provide a fixing structure for a concrete wall casting template.

[0005] To solve the above technical problems, the technical solution provided by the utility model is as follows:

[0006] A fixing structure for a concrete wall casting template includes a tie rod. At both ends of the tie rod, a template baffle, a steel bar pressing member, and a locking nut are respectively installed in sequence from inside to outside.

[0007] The template baffle and the steel bar pressing member located at the same end of the tie rod are respectively located inside and outside the template, and the outer side wall of the template baffle abuts against the inner side wall of the template, and the inner side wall of the steel bar pressing member abuts against the outer side wall of the template.

[0008] Further, the steel bar pressing member includes a base sleeved on the end of the tie rod and a U-shaped pressing block. One side of the base abuts against the outer side wall of the template.

[0009] Two pressing plates are rotatably installed inside the U-shaped pressing block, and a steel bar groove for cooperating with the pressing plates is formed on the base.

[0010] A guide post is arranged in the middle of the U-shaped pressing block, a guide cylinder is sleeved on the outer side of the guide post, and a pressing plate is arranged on the side of the guide cylinder away from the U-shaped pressing block; a compression spring is sleeved on the outer side of the guide post, and both ends of the compression spring abut against the U-shaped pressing block and the pressing plate respectively.

[0011] Driving plates are arranged at the ends of the two pressing plates close to each other, and the driving plates are attached to the side of the pressing plate away from the U-shaped pressing block.

[0012] At one end where the two pressing plates are away from each other, buckles are provided, and buckle grooves adapted to the buckles are formed on the base.

[0013] Furthermore, on one side of the base that abuts against the outer side wall of the formwork, a plurality of evenly distributed positioning pointed cones are provided.

[0014] Furthermore, on one side of the pressing plate close to the steel bar groove, a plurality of evenly distributed pressing blocks are provided.

[0015] Furthermore, the formwork baffle is fixedly installed or threadedly installed on the tie rod.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. For the concrete wall casting formwork fixing structure provided by the present utility model, the distance between the two formworks is fixed by the tie rod and the formwork baffles at both ends of the tie rod, and the position of the formwork is fixed by the cooperation of the steel bar pressing member and the lock nut with the formwork baffle; at the same time, multiple concrete wall casting formwork fixing structures can also be used. Steel bars are loaded into the steel bar pressing member to further fix the formwork. While ensuring that the casting formwork has sufficient strength when casting the concrete wall, it can also effectively prevent the formwork from deforming.

[0018] 2. For the concrete wall casting formwork fixing structure provided by the present utility model, by providing buckles and driving plates at both ends of the pressing plate, when the lock nut squeezes the U-shaped pressing block and the U-shaped pressing block approaches the base, the side wall of the base can squeeze the driving plate, causing the pressing plate to rotate around the U-shaped pressing block, and the buckle at one end of the pressing plate can be snapped into the buckle groove on the base, so that the pressing plate will not bend after the steel bar receives a force perpendicular to the formwork and outward; by providing a guide post, a guide cylinder and a compression spring, when the driving plate squeezes the pressing plate located at the end of the guide cylinder, the compression spring can be compressed. After loosening the lock nut, under the reaction force of the compression spring, the driving plate is squeezed by the pressing plate, causing the pressing plate to rotate around the U-shaped pressing block, so that the buckle can automatically withdraw from the buckle groove.
