Concrete guardrail force transmission rod isolation layer winding tool

Abstract

This utility model provides a tool for wrapping the isolation layer on concrete guardrail dowel bars. Relating to the field of construction technology, the tool includes a placement frame comprising two stabilizing components spaced apart and opposite to each other, and a horizontal bar fixed between the two stabilizing components and extending in the left-right direction. The two ends of a Z-shaped dowel bar are placed on the stabilizing components, allowing the Z-shaped dowel bar to rotate under gravity, thus wrapping the isolation layer around it. After placing the Z-shaped dowel bar at the top, the worker manually rotates the Z-shaped dowel bar while simultaneously holding the isolation layer and gradually wrapping it around the dowel bar. This method not only significantly improves the speed of installing the isolation layer at both ends of the Z-shaped dowel bar but also effectively reduces the physical burden on the worker during operation. By setting a protective adhesive in the work area, when the Z-shaped dowel bar is placed on the surface of the protective adhesive, the adhesive can buffer the direct force between the dowel bar and the contact surface.

Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a tool for wrapping the isolation layer of concrete guardrail force transmission rods. Background Technology

[0002] A dowel bar is a round steel bar arranged at regular intervals along the transverse joints of a cement concrete pavement slab, in the center of the slab thickness. One end is fixed inside one side slab, while the other end can slide inside the adjacent side slab. Its function is to transfer traffic loads between two pavement slabs and prevent misalignment, increase stress transfer between adjacent concrete blocks to prevent uneven settlement of the concrete pavement caused by excessive local stress, and transfer stress so that adjacent concrete blocks share the load.

[0003] The current production process for dowel bars involves painting the bars first, followed by the installation of the insulating layer. Because painting and insulating layer installation must be performed sequentially and cannot be done simultaneously, the workflow is not tightly integrated. This significantly increases the time required for each dowel bar from painting to insulating layer installation, resulting in low overall efficiency and making it difficult to meet the ever-increasing production demands. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for wrapping the isolation layer of concrete guardrail dowel bars, which aims to solve the problem of low work efficiency caused by the fact that dowel bars in the prior art need to be painted before the isolation sleeve is installed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the concrete guardrail force transmission bar isolation layer winding tool includes a placement frame and a Z-shaped force transmission bar;

[0006] The placement rack includes two stabilizing components spaced apart from each other and arranged opposite each other, and a crossbar fixed between the two stabilizing components and extending in the left-right direction.

[0007] The two ends of the Z-shaped force transmission rod are placed on the stabilizing component, so that the Z-shaped force transmission rod can rotate under the action of gravity, so that the isolation layer is wrapped around the Z-shaped force transmission rod.

[0008] Preferably, the stabilizing component includes a triangular support frame and a support rod;

[0009] The support rod is fixed inside the triangular support frame;

[0010] The crossbar is fixed to the upper side of the two support rods, and both ends of the crossbar extend through the support rods and are fixedly connected to the triangular support frame.

[0011] Preferably, the triangular support frame includes a first leg, a second leg, and a third leg;

[0012] The first leg, the second leg, and the third leg all slope from bottom to top and from outside to inside, and the lengths of the first leg and the second leg are longer than the length of the third leg;

[0013] The first leg and the second leg are cross-fixed to form a lower opening facing downwards and an upper opening facing upwards;

[0014] The upper end of the third leg is fixedly connected to the intersection of the first leg and the second leg;

[0015] The support rod is located at the lower opening, and its front and rear ends are fixedly connected to the first leg and the second leg, respectively.

[0016] The left and right ends of the crossbar are fixed to the support rod.

[0017] Preferably, the crossbar passes through the support rod;

[0018] The lower end of the third leg is fixed to a crossbar that passes through the support rod.

[0019] Preferably, the upper opening forms a V-shaped structure, and the Z-shaped force transmission rod is placed inside the V-shaped structure.

[0020] Preferably, protective adhesive is affixed to the upper end of the third leg at the intersection point where it connects with the first and second legs.

[0021] The beneficial effects are: 1. After placing the Z-shaped force transmission rod at the top, the worker manually rotates the Z-shaped force transmission rod while simultaneously holding the insulating layer and gradually wrapping it around the rod. This method not only significantly increases the speed of installing the insulating layer at both ends of the Z-shaped force transmission rod, but also effectively reduces the physical burden on the worker during the operation.

[0022] 2. By setting a protective adhesive in the work area, when the Z-type dowel bar is placed on the surface of the protective adhesive, the protective adhesive can effectively buffer the direct force between it and the contact surface, thereby avoiding structural damage to the Z-type dowel bar due to collision, friction or compression, and significantly improving its safety and integrity during placement.

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0030] The concrete guardrail dowel bar isolation layer wrapping tool is mainly used when the Z-type dowel bar 2 is placed on the placement frame, and then the worker manually rotates the Z-type dowel bar 2. Then the worker holds the isolation layer 8. During the rotation of the Z-type dowel bar 2, the isolation layer 8 can be wrapped around the Z-type dowel bar 2, which not only reduces the labor intensity of the worker, but also improves the efficiency of the isolation layer 8 wrapping around both ends of the Z-type dowel bar 2.

[0031] In this embodiment, the force transmission rod isolation layer winding tool includes a placement frame and a Z-shaped force transmission rod 2. The placement frame is placed on the ground, and then the Z-shaped force transmission rod 2 is placed on the placement frame. After the worker moves the Z-shaped force transmission rod 2, the isolation layer 8 can be wound on the Z-shaped force transmission rod 2, which improves work efficiency.

[0032] like Figures 1-4 As shown, the placement frame includes two stabilizing components spaced apart and arranged opposite each other, and a crossbar 102 fixed between the two stabilizing components and extending in the left and right direction. The two ends of the Z-shaped force transmission rod 2 are respectively placed on the stabilizing components. The Z-shaped force transmission rod 2 first rotates under the influence of worker fluctuation, and then rotates under the action of gravity, so that the isolation layer 8 is wrapped around the Z-shaped force transmission rod 2, without the need for worker to manually wrap the isolation layer 8.

[0033] In this embodiment, when the Z-shaped force transmission rod 2 rotates, one end of the Z-shaped force transmission rod 2 can be wrapped with the isolation layer 8, and at the same time, the other end of the Z-shaped force transmission rod 2 can be coated with a coating. The coating is made of resin or with added release agent. The isolation layer 8 is made of polyethylene or polyethylene film. The structure and principle of resin, polyethylene with added release agent, and polyethylene film are existing technologies and will not be described in detail here.

[0034] Specifically, the stabilizing component includes a triangular support frame 3 and support rods 4; the support rods 4 are fixed inside the triangular support frame 3; the crossbar 102 is fixed on the upper side of the two support rods 4, and the two ends of the crossbar 102 pass through the support rods 4 and are fixedly connected to the triangular support frame 3.

[0035] The triangular support frame 3 includes a first leg 301, a second leg 302, and a third leg 303. The first leg 301, second leg 302, and third leg 303 are all inclined from bottom to top and from outside to inside. The lengths of the first leg 301 and second leg 302 are longer than the length of the third leg 303. The first leg 301 and second leg 302 are supported on the ground to make the triangular support frame 3 more stable during use. The first leg 301 and second leg 302 are cross-fixedly connected, forming a lower opening 5 facing downwards and an upper opening 6 facing upwards. The lower opening 5... The arrangement of the upper opening 6 facilitates the placement of the Z-shaped force transmission rod 2. The upper end of the third leg 303 is fixedly connected to the intersection of the first leg 301 and the second leg 302. The support rod 4 is located at the lower opening 5, and its front and rear ends are fixedly connected to the first leg 301 and the second leg 302, respectively. The left and right ends of the crossbar 102 are fixed to the support rod 4. The first leg 301, the second leg 302 and the third leg 303 form a triangular support structure to ensure the stable placement of the Z-shaped force transmission rod 2.

[0036] The crossbar 102 passes through the support rod 4; the lower end of the third leg 303 is fixed to the crossbar 102 that passes through the support rod 4.

[0037] like Figures 1-5 As shown, the Z-shaped force transmission rod 2 is placed inside the upper opening 6, making it easy for the Z-shaped force transmission rod 2 to rotate and be supported.

[0038] Specifically, the upper opening 6 forms a V-shaped structure, and the Z-shaped force transmission rod 2 is placed inside the V-shaped structure.

[0039] Protective adhesive 7 is affixed to the intersection of the upper end of the third leg 303 and the first leg 301 and the second leg 302. With the setting of the protective adhesive 7, the protective adhesive 7 can effectively buffer the direct force between the Z-shaped force transmission rod 2 and the contact surface, thereby avoiding structural damage to the Z-shaped force transmission rod 2 due to collision, friction or compression, and significantly improving its safety and integrity during placement.

[0040] Working principle: In use, place the placement frame on the ground, and then place the Z-shaped force transmission rod 2 on the placement frame to form... Figure 1In this state, the worker first fixes one end of the isolation layer 8 to the Z-shaped force transmission rod 2, and then rotates the Z-shaped force transmission rod 2. During the rotation, the Z-shaped force transmission rod 2 will drive the isolation layer 8 to wrap around the Z-shaped force transmission rod 2, which reduces the labor intensity of the worker and improves the installation efficiency of the isolation layer 8. At the same time, while the isolation layer 8 is being wrapped at one end of the Z-shaped force transmission rod 2, the other end of the Z-shaped force transmission rod 2 can also be coated. If the coating is not required, the other end of the Z-shaped force transmission rod 2 can be wrapped after one end is finished.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention.
