Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a tensile steel bar component in a prefabricated part. Background Art

[0002] The tensile performance of prefabricated parts refers to the ability of prefabricated components to resist fracture or failure when subjected to tensile loads. This is one of the important indicators for evaluating the safety, stability and durability of prefabricated components.

[0003] In precast concrete structures, especially when it comes to reinforced concrete precast parts, the tensile properties depend mainly on two aspects:

[0004] 1. Tensile performance of steel bars: Prefabricated parts are usually equipped with steel bars of different specifications and grades. As the main tensile member of the prefabricated parts, the tensile strength, elastic modulus, yield strength and ultimate tensile strength of the steel bars determine the performance of the prefabricated parts under tension.

[0005] 2. Tensile properties of concrete: Although the tensile strength of ordinary concrete is much lower than its compressive strength, the overall tensile properties of precast concrete parts can be effectively improved through reasonable design of reinforcement.

[0006] A skeleton formed by connecting several steel bars together can be buried in a prefabricated part to effectively improve its strength. However, the skeleton in the existing prefabricated part is usually prepared by welding or steel wire bundling. It can be seen that welding fixes the connection position and the prepared skeleton cannot be properly adjusted again. Steel wire bundling can solve the above problem, but steel wire bundling steel bars has the problems of high labor intensity and low operation efficiency. Summary of the invention

[0007] The purpose of the utility model is to provide a tensile steel bar component in a prefabricated part with high stability and compact structure in view of the above problems existing in the prior art.

[0008] The purpose of the utility model can be achieved through the following technical solutions:

[0009] A tensile steel bar component in a prefabricated part, wherein the prefabricated part has a plurality of steel bars, which are connected together to form a skeleton for reinforcing the prefabricated part. The tensile steel bar component is located between the ends of two adjacent steel bars, and comprises a connecting block 1, a connecting block 2 and a locking assembly. The connecting block 1 has a positioning hole 1 for passing the steel bar, and the connecting block 2 has a positioning hole 2 for passing the steel bar. The locking assembly is connected to the connecting block 1 and the connecting block 2, and the steel bar at the first positioning hole is pressed tightly together with the steel bar at the second positioning hole under the action of the locking assembly.

[0010] Two adjacent steel bars in the prefabricated component skeleton are connected by this tensile steel bar component.

[0011] Specifically, one of the steel bars is passed through the first positioning hole of the first connecting block, and the other steel bar is passed through the second positioning hole of the second connecting block.

[0012] The locking assembly is connected to the connection block 1 and the connection block 2. At the same time, under the action of the locking assembly, the steel bar at the first positioning hole and the steel bar at the second positioning hole can be tightly attached together, and finally the two adjacent steel bars are stably fixed together.

[0013] In the tensile steel bar component in the above-mentioned prefabricated part, the locking assembly includes a flange one, a flange two and screws. The flange one is fixedly connected to the connecting block one and the flange one is located at the upper part of the positioning hole one. The flange two is fixedly connected to the connecting block two and the flange two is located at the lower part of the positioning hole two. The screws are passed through and connected to the flange one and the flange two. The steel bars at the positioning hole one and the steel bars at the positioning hole two can be tightly pressed between the flange one and the flange two.

[0014] Since the two adjacent steel bars are located between the first convex edge and the second convex edge, after the screws are passed through and connected to the first convex edge and the second convex edge, the ends of the two adjacent steel bars can be pressed tightly through the first convex edge and the second convex edge, thereby achieving a fixed connection between the two adjacent steel bars.

[0015] In the tensile steel bar component of the above-mentioned prefabricated part, the flange 1 and the connecting block 1 are an integrated structure.

[0016] In the tensile steel bar component of the above-mentioned prefabricated part, the second flange and the second connecting block are an integrated structure.

[0017] In the tensile steel bar component in the above-mentioned prefabricated part, the lower part of the connecting block also has a supporting edge 1, and the above-mentioned convex edge 2 abuts against the upper part of the supporting edge 1.

[0018] In the tensile steel bar component in the above-mentioned prefabricated part, the support edge 1 and the connecting block 1 are an integrated structure.

[0019] In the tensile steel bar component in the above-mentioned prefabricated part, the upper part of the second connecting block also has a second supporting edge, and the first convex edge abuts against the lower part of the second supporting edge.

[0020] In the tensile steel reinforcement member in the above-mentioned prefabricated part, the second supporting edge and the second connecting block are an integrated structure.

[0021] The second convex edge can be supported by the first supporting edge, and the first convex edge can be supported by the second supporting edge. Such a structure can buckle and connect the connecting block one with the connecting block two to ensure the connection stability.

[0022] In the tensile steel bar component in the above-mentioned prefabricated part, the support edge has a through avoidance hole, and the lower end of the above-mentioned screw is located at the avoidance hole.

[0023] The lower end of the screw is located at the avoidance hole, and such a structure can prevent the screw from contacting the supporting edge.

[0024] The tensile steel bar component in the above-mentioned prefabricated part also includes a flexible damping block, which is located between the first connecting block and the second connecting block and can be tightly pressed between the side portions of two adjacent steel bars.

[0025] The damping block is made of rubber material and has two functions:

[0026] First, avoid rigid contact between two adjacent steel bars;

[0027] Second, it increases the contact resistance between two adjacent steel bars and improves the connection stability.

[0028] Compared with the prior art, the tensile steel bar component in the prefabricated part has higher practicality because the relative positions between two adjacent steel bars can be properly adjusted after the screws are loosened.

[0029] Once the screws are retightened, two adjacent steel bars can be stably positioned between the connecting block 1 and the connecting block 2, and the stability is relatively high.

[0030] At the same time, since the first connecting block and the second connecting block are arranged adjacent to each other, the structure of the entire steel bar component is relatively compact and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
