Description

Technical Field

[0001] This utility model belongs to the field of road and bridge construction technology, and in particular relates to a steel bar connection device for road and bridge construction. Background Technology

[0002] Road and bridge construction refers to the specific construction plans and implementation methods formulated to complete the construction of bridges on roads in road and transportation construction projects. In road and bridge construction, reinforced concrete structures are an important component, playing a role in strengthening and stabilizing the project. For example, long-span bridges are often constructed using techniques such as cable hoisting of reinforced concrete structures, cantilever formwork casting, and external scaffolding. However, these techniques still have the following drawbacks in practical use:

[0003] During the construction of roads and bridges, in order to ensure the strength and other data of the bridges after construction, it is necessary to ensure that the steel bars are placed in the right positions and that the ends of the steel bars are connected together through the connecting structure. Then, they are installed together through the connecting structure. During the installation operation, due to construction and other factors, the center lines of the connected positions of the steel bars are not on the same straight line, which affects the use.

[0004] During road and bridge construction, when steel bars are connected together, the gap between the two steel bars is directly pressed together by the installation structure, so that the two steel bars with aligned ends are connected together. However, when there are a large number of steel bars, and each one needs to be matched and locked one by one, the operation is relatively troublesome and not convenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide a steel bar connection device for road and bridge construction. By setting a connecting plate, a center plate, an installation baffle, and a clamping plate, it solves the problems that it is not convenient to determine the coaxiality of the steel bars during the road and bridge construction process, and that it is not convenient to align the two steel bars during installation.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a rebar connection device for road and bridge construction, comprising a connecting plate, a central plate, an installation baffle, and a clamping plate. Connecting plates are fixed to the top and bottom of the central plate. Two connecting plates are positioned between two installation baffles, with their corresponding upper and lower ends fixed to the upper and lower edges of the installation baffles near the central plate. Clamping plates are provided on the adjacent sides of the connecting plates on both sides of the central plate. The clamping plates on the two connecting plates are symmetrical. During operation, the two connecting plates are connected together via the central plate and the installation baffles. The central plate restricts the corresponding position of the rebar. When operating via the installation baffles, the rebar is installed in the correct position. When operating via the clamping plates, the rebar entering between the two connecting plates is locked and secured.

[0008] Furthermore, T-shaped strips are fixed at equal intervals on the opposite sides of the two connecting plates. The T-shaped strips on the two connecting plates are symmetrically arranged. When the connecting plates are in operation, the T-shaped strips form a T-shape, which increases the interlocking strength between the steel reinforcement connection position and the concrete after pouring.

[0009] Furthermore, the mounting baffle has a through-hole in the center, and a movable sleeve is fixed to the outside of the movable hole on the side of the mounting baffle away from the connecting plate. The inner diameter of the movable sleeve is equal to the inner diameter of the movable hole. When the mounting baffle is working, the connecting steel bar is moved through the movable hole and the movable sleeve.

[0010] Furthermore, a limiting ring is fixed at the center of both sides of the central plate. The inner diameter of the limiting ring is equal to the inner diameter of the movable hole. The central plate restricts the position of the reinforcing bar through the limiting ring.

[0011] Furthermore, the clamping plate is inclined, and an arc-shaped opening is provided at the bottom of the clamping plate. The two clamping plates corresponding to each other are in contact with each other, and the clamping plate moves to set the position of the reinforcing bar through the arc-shaped opening.

[0012] Furthermore, a rotating rod is fixed to the side of the clamping plate away from the arc-shaped opening, and connecting ear plates are fixed to both ends of the rotating rod. The two connecting ear plates are respectively fixed to the two sides of the corresponding connecting plate. An arc-shaped spring is fixed to the side of the clamping plate near the center plate. The side of the arc-shaped spring away from the clamping plate is fixed to the connecting plate. When the clamping plate is working, the connecting ear plates connected by the rotating rod are connected to the connecting plate. When the arc-shaped spring is working, it cooperates with the clamping plate to clamp the position of the reinforcing bar.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of inconvenient setting of rebar coaxiality during road and bridge construction by setting a connecting plate, a center plate, an installation baffle, and a clamping plate. One end of the bridge rebar is inserted into the movable sleeve on the installation baffle, then passes through the movable hole on the installation baffle, and then through two contacting clamping plates. The rebar extends into the limiting ring on the center plate, and its position is restricted by the limiting ring and abuts against the center plate. Then, another bridge rebar is passed through another movable sleeve and abuts against the center plate, so that the central axes of the two connected rebars are on the same straight line, making it more convenient to set the rebar coaxiality during road and bridge construction.

[0015] This invention solves the problem of inconvenient alignment of two reinforcing bars during bridge and road construction by setting up a connecting plate, a mounting baffle, and a clamping plate. After the reinforcing bar passes through the movable sleeve and enters between the two connecting plates, it enters the arc-shaped openings on the two clamping plates until it enters the limiting ring. At this point, the elasticity of the arc-shaped spring pushes the clamping plate, and the clamping plate at the arc-shaped opening presses against the reinforcing rib of the reinforcing bar, forming a locking structure. This ensures that the position of the reinforcing bar between the two connecting plates is determined. During bridge and road construction, the alignment of the two reinforcing bars only requires passing through the mounting baffle and abutting against the center plate, and being clamped by the clamping plate, making it more convenient to use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-5 This utility model is a rebar connection device for road and bridge construction, including a connecting plate 1, a central plate 2, an installation baffle 3, and a clamping plate 4. The top and bottom of the central plate 2 are fixed with connecting plates 1. When the central plate 2 is working, it restricts the corresponding positions of two rebars. The two installation baffles 3 are connected together by the connecting plates 1. The two connecting plates 1 are set between the two installation baffles 3, and the upper and lower corresponding ends of the two connecting plates 1 are fixed at the upper and lower edges of the installation baffles 3 near the central plate 2. When the installation baffles 3 are working, they are connected to the connecting plates 1, so that the ends of the two connecting plates 1 are connected together. The connecting plates 1 on both sides of the central plate 2 are provided with clamping plates 4 on their adjacent sides. The clamping plates 4 on the two connecting plates 1 are symmetrical to each other. When the rebar passes between the two contacting clamping plates 4, a locking structure is formed to restrict the position of the rebar.

[0026] Specifically, T-shaped strips 101 are fixed at equal intervals on the opposite sides of the two connecting plates 1. The T-shaped strips 101 on the two connecting plates 1 are symmetrically arranged. When the connecting plates 1 are working, the T-shaped strips 101 interlock with the poured concrete, increasing the bonding strength between the connecting plates 1 and the concrete.

[0027] Furthermore, a movable hole 302 is provided through the center of the mounting baffle 3. A movable sleeve 301 is fixed on the outside of the movable hole 302 on the side of the mounting baffle 3 away from the connecting plate 1. The inner diameter of the movable sleeve 301 is equal to the inner diameter of the movable hole 302. When the mounting baffle 3 is working, the reinforcing bars are connected through the movable hole 302 and the corresponding reinforcing bars are fitted through the movable sleeve 301.

[0028] Furthermore, a limiting ring 201 is fixed at the center of both sides of the center plate 2. The inner diameter of the limiting ring 201 is equal to the inner diameter of the movable hole 302. The center plate 2 restricts the corresponding ends of the reinforcing bars through the limiting ring 201.

[0029] The operation process of this embodiment is as follows: During operation, when setting up, first insert one end of the bridge steel bar into the movable sleeve 301 on the mounting baffle 3, then pass through the movable hole 302 on the mounting baffle 3, and then pass through two mutually contacting clamping plates 4. The steel bar extends into the limiting ring 201 on the center plate 2, and after the position is restricted by the limiting ring 201, it abuts against the center plate 2. Then, another bridge steel bar is passed through another movable sleeve 301 and abuts against the center plate 2, so that the central axes of the two connected steel bars are on the same straight line. After most of the steel bars are installed, the bridge concrete is poured. After pouring, the T-shaped strip 101 on the connecting plate 1 interlocks with the concrete, increasing the bonding strength between the steel bar connection and the concrete. Specific Implementation Example 2

[0030] Please see Figure 1 , 2 5. Based on the specific embodiment one, the clamping plate 4 is inclined and has an arc-shaped opening 404 at the bottom. The two clamping plates 4 corresponding to each other are in contact with each other. When the clamping plate 4 is working, it accommodates the reinforcing bar through the inclined arc-shaped opening 404 and the two clamping plates 4 are in contact with each other. When the reinforcing bar passes between the two contacting clamping plates 4, a locking structure is formed between the reinforcing bar and the two contacting clamping plates 4, which restricts the position of the reinforcing bar.

[0031] Specifically, a rotating rod 401 is fixed on the side of the clamping plate 4 away from the arc-shaped opening 404. Both ends of the rotating rod 401 are fixed with connecting ear plates 402. The two connecting ear plates 402 are respectively fixed on both sides of the corresponding connecting plate 1. An arc-shaped spring 403 is fixed on the side of the clamping plate 4 near the center plate 2. The side of the arc-shaped spring 403 away from the clamping plate 4 is fixed to the connecting plate 1. When the clamping plate 4 is working, it is rotatably connected to the connecting ear plate 402 through the rotating rod 401. After the connecting ear plate 402 is connected to the connecting plate 1, the position of the connecting ear plate 402 is restricted. When working, the arc-shaped spring 403 presses the clamping plate 4 to maintain the two clamping plates that are in contact with each other.

[0032] The operation process of this embodiment is as follows: When the steel bar passes through the movable sleeve 301 and enters between the two connecting plates 1, it enters the arc-shaped opening 404 on the two clamping plates 4 until it enters the limiting ring 201. At this time, the elasticity of the arc-shaped spring 403 causes the clamping plate 4 to be pushed. The clamping plate 4 at the position of the arc-shaped opening 404 presses against the reinforcing rib of the steel bar to form a locking structure, so that the position of the steel bar between the two connecting plates 1 is determined.
