Description

Technical Field

[0001] This utility model relates to the field of arc-shaped expansion joints, specifically to an arc-shaped expansion joint with multiple inclined sides. Background Technology

[0002] Bridge expansion joints are crucial structural components in bridge engineering. They are mainly used to regulate bridge structural displacement caused by factors such as temperature changes, vehicle loads, and concrete shrinkage and creep, ensuring bridge safety and driving comfort. Bridge expansion joints are installed between the ends of two beams, between the beam end and the abutment, or at the hinged joints of the bridge. Through free expansion and contraction parallel to or perpendicular to the bridge axis, they ensure structural stability.

[0003] At the bottom of bridge expansion joints, filler is installed. The filler is mostly made of elastic material, such as rubber strips, which are used to seal the expansion joint. When a vehicle travels from one side to the other, the change in gravity from one side to the other causes different forces on the two sides of the expansion joint, which in turn causes the filler inside the expansion joint to bounce up and down. Utility Model Content

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a multi-sided inclined arc-shaped expansion joint, including an installation part installed on the beam, wherein the installation part is symmetrically distributed;

[0006] The top of the mounting part is provided with a first telescopic part, and one end of the first telescopic part is provided with a second telescopic part, forming an arc-shaped expansion joint between the first telescopic part and the second telescopic part.

[0007] The first telescopic part includes a first protrusion and a second protrusion. The first protrusion and the second protrusion are both disposed on the side of the mounting part, and the first protrusion and the second protrusion are arranged at intervals between each other.

[0008] The second telescopic part includes a first docking block and a second docking block. The first docking block and the second docking block are both disposed on the side of the other mounting part, and the first docking block and the second docking block are arranged at intervals.

[0009] Furthermore, the side of the first protrusion away from the mounting part is a first inclined surface, which is designed to slope from the upper right to the lower left of the first protrusion, and one side of the first mating block is designed to be inclined to match the first inclined surface.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the side of the second protrusion away from the mounting part is a second inclined surface. The second inclined surface is designed to slope from the lower right to the upper left of the second protrusion, and one side of the second mating block is designed to be inclined to match the second inclined surface.

[0012] Furthermore, the first inclined plane and the second inclined plane are arranged in an intersecting pattern.

[0013] Furthermore, the mounting part includes a mounting plate, a side plate, and a mounting groove. The mounting plate is fixedly mounted on the beam, the side plate is mounted on the side wall of the mounting plate, and the mounting groove is located between the mounting plate and the beam.

[0014] Furthermore, the interior of the mounting groove is provided with a connecting part, which includes embedded steel bars, connecting steel bars and longitudinal steel bars. The embedded steel bars are fixedly installed in the inner cavity of the mounting groove, the connecting steel bars are fixedly installed at the bottom of the side plate, and the longitudinal steel bars pass through the embedded steel bars and the connecting steel bars.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] This invention utilizes a first and a second telescopic section on the mounting plate to form an expansion joint using a first protrusion, a second protrusion, a first mating block, and a second mating block. The filler material located in this expansion joint can be fixed vertically and vertically, preventing it from bouncing. Combined with the arc-shaped design of the mounting plate's sidewall, the overall expansion joint is arc-shaped. Compared to a straight type, it has a larger contact area and a gradual transition at the joint, avoiding stress concentration points at right-angle joints. Furthermore, the arc-shaped expansion joint, combined with the filler material, absorbs the expansion and contraction through the elastic deformation of the material. At the same time, the arc-shaped design extends the deformation path of the material, enhancing durability. Attached Figure Description

[0032] When the two mounting plates 201 retract and move closer together, the first protrusion 301 and the second protrusion 302, along with the first mating block 401 and the second mating block 402, will move closer together and squeeze the filling material in the middle. The elasticity of the filling material is used to offset the horizontal impulse. The squeezing and limiting effect of the first protrusion 301, the first mating block 401, the second protrusion 302, and the second mating block 402 can also suppress the jumping of the rubber belt and ensure the stability of the expansion joint.

[0033] Please see Figure 2 and Figure 3 In this embodiment, the side of the first protrusion 301 away from the mounting part 2 is the first inclined surface 6. The first inclined surface 6 is designed to be inclined from the upper right to the lower left of the first protrusion 301. One side of the first docking block 401 is designed to be inclined to fit with the first inclined surface 6, so as to ensure that the first protrusion 301 and the first docking block 401 can fit together during the process of approaching, and limit the filling material in the middle.

The second inclined surface 7 is designed to be inclined from the lower right to the upper left of the second protrusion 302. One side of the second mating block 402 is designed to be inclined to fit with the second inclined surface 7, so as to ensure that the second protrusion 302 and the second mating block 402 can fit together during the process of approaching, and limit the filling material in the middle.

[0035] Please see Figure 2 and Figure 3 In this embodiment, the first inclined surface 6 and the second inclined surface 7 are arranged in a cross pattern, so that the first protrusion 301, the second protrusion 302, the first docking block 401 and the second docking block 402 can cross-limit the filler. With the cross-fitting state, the effect of suppressing jumping can be achieved.

[0036] Please see Figure 2 and Figure 3 The mounting part 2 in this embodiment includes a mounting plate 201, a side plate 202 and a mounting groove 203.

The arc-shaped mounting plate 201 can form an arc-shaped expansion joint. The arc-shaped expansion joint can guide the deformation direction through the curvature change of the arc structure. Compared with the straight type, it has a larger contact area and the joint is gradually transitioned, avoiding the stress concentration point of the right angle joint. In addition, the arc-shaped expansion joint is combined with the filler, which absorbs the expansion and contraction through the elastic deformation of the material. At the same time, the arc design extends the deformation path of the material and enhances durability.
