Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bridge reinforcement, and in particular relates to a municipal road bridge crack reinforcement structure. Background Art
[0002] Most road bridges are made of cast cement. As the construction time of bridges increases and the traffic volume increases, small cracks will inevitably appear in the bridges cast by cement. Therefore, the cracks in the bridges need to be reinforced. Bridge reinforcement generally refers to restoring or improving the bearing capacity of existing bridges by strengthening components and improving structural performance, so as to extend their service life and meet the requirements of modern transportation.
[0003] Most of the existing municipal road bridge crack reinforcement structures adopt a method of directly filling the gaps with filling materials and then re-laying the surface cushion layer to repair them. However, due to the difference in internal filling materials, the stress level of this repair method is different from that of the surrounding roadbed. Therefore, the reinforcement stability is not high and it is still easy to crack again. Therefore, it is necessary to provide a municipal road bridge crack reinforcement structure to solve the above problems. Utility Model Content
[0004] The technical problem to be solved by the present invention is that most existing road and bridge reinforcement structures are merely filled and repaired at the cracks, which can only repair the surface and still cause cracks to occur during use.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a municipal road bridge crack reinforcement structure, including a roadbed and a crack body, wherein the crack body is located on the roadbed, and the top of the crack body is covered with a repair plate, and a guide slide is provided in the middle of the bottom of the repair plate, and the inside of the guide slide is slidably connected to a movable plate, and studs passing through the repair plate are provided at both ends of the movable plate, and the studs are located at both ends of the repair plate and are connected with nuts, and the two sides of the movable plate are rotatably connected to a plurality of symmetrically arranged follow-up pull plates, and the other end of the follow-up pull plate is rotatably connected to an inner pull plate, the inner pull plate is slidably connected to the bottom of the repair plate, and an anchor nail is passed through the outer side of the inner pull plate, and a protective cover is provided on the repair plate above the anchor nail and the inner pull plate.
[0006] Furthermore, the repair plate and the protective cover are integrally formed into a stepped structure, wherein the protective cover is triangular and located on both sides of the repair plate as two sides of the trapezoidal structure.
[0007] Furthermore, movable openings matching the shape of the follower pull plate are provided on both sides of the guide slot.
[0008] Furthermore, corresponding movable grooves are provided at the bottom of the repair plate at the follower pull plates on both sides of the guide slide groove.
[0009] Furthermore, sliding grooves having the same thickness as the sum of the inner pull plate and the follower pull plate are provided on both sides of the bottom of the repair plate, and the width of the sliding grooves matches the shape of the inner pull plate.
[0010] Furthermore, the anchor nail is composed of a limiting cap at the top and a nail body at the bottom, wherein the limiting cap is located above the inner pull plate, and the nail body passes through one end of the inner pull plate away from the repair plate.
[0011] Furthermore, the protective cover is located at both ends of the plurality of follower pull plates and is fixedly connected to the repair plate by screws.
[0012] The advantages of this utility model compared with the prior art are:
[0013] This crack reinforcement structure is achieved by setting multiple anchors on both sides of the crack body after filling the crack body, and stretching the anchors on both sides toward the middle through the repair plate, so that the crack body is squeezed more tightly, thereby achieving the effect of fixed reinforcement, and dispersing the force from above through the repair plate, thereby reducing the pressure on the crack body and increasing the service life after repair.
