Description

Technical Field

[0001] This utility model relates to the field of expansion joint technology, specifically to a spliced ​​arc-shaped expansion joint. Background Technology

[0002] Building expansion joints, also known as expansion joints, are structural joints installed at appropriate locations along the construction joint direction of a building or structure to prevent cracks or damage to the structure caused by changes in climate temperature (thermal expansion and contraction). Expansion joints divide building components above the foundation, such as walls, floors, and roofs (except for wooden roofs), into two independent parts, allowing the building or structure to expand and contract horizontally along its length.

[0003] In common expansion joints, the gaps between steel plates are fixed in both structure and size due to the fixed structure of the expansion joint. This is especially true for expansion joints used in bridge environments, where the actual usage of bridges, as public facilities, varies depending on the environment. Therefore, expansion joints with a single structure are difficult to adapt to specific practical situations. Hence, a spliced ​​arc-shaped expansion joint is proposed to solve the aforementioned problems. Utility Model Content

[0004] Based on the above description, this utility model provides a spliced ​​arc-shaped expansion joint to solve the problem that existing expansion joints, due to their simple structure, do not fit the actual situation when used on public facilities such as bridges.

It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0035] Please see Figures 1-5 A spliced ​​arc-shaped expansion joint includes: two steel structures 1, a connecting block 2, and a mounting cover 3;

[0036] Each of the two steel structures 1 is provided with a connecting block 2 on one side of the opposite side. The connecting block 2 is connected to the steel structure 1 by a mounting cover 3 and screws. Rubber gaskets are provided between each pair of steel structure 1, connecting block 2 and mounting cover 3 to buffer the impact force, thereby reducing the wear between the three structures.

[0037] The steel structure 1 includes a steel structure body 11, and connecting steel bars 15 are provided on opposite sides of the two steel structure bodies 11.

[0038] The top of the steel structure body 11 is provided with an installation groove 12, and the bottom wall of the installation groove 12 is provided with an inclined groove 16. Each of the two steel structure bodies 11 is provided with an opening groove 14 and a main inclined surface 13 that communicate with the inclined groove 16 on one side.

[0039] Based on the above, the installation of the groove 12, the inclined groove 16 and the opening groove 14 enables the connecting block 2 to be initially connected to the steel structure 1 by snap-fit. The main inclined surface 13 can support the connecting block 2. At the same time, the connecting steel bar 15 is embedded in the cement to firmly connect the steel structure 1 to the main building, making the entire expansion joint a part of the main building, thus improving the integrity and stability of the structure.

[0040] like Figure 6 As shown, the connecting block 2 includes a first connecting block 21, a second connecting block 22, and a third connecting block 23. The structures of the first connecting block 21, the second connecting block 22, and the third connecting block 23 are the same except for the shape of the gap 30.

[0041] like Figure 7 and Figure 8 As shown, the first connecting block 21 includes an installation crossbar 27 disposed inside the inclined groove 16. A connecting plate 26 penetrating the opening groove 14 is disposed on the circumferential surface of the inclined groove 16. A main body block 24 is disposed on the side of the connecting plate 26 away from the installation crossbar 27. A gap 30 is disposed between the two main body blocks 24. A rubber strip 4 is disposed inside the gap 30. A first-stage inclined surface 25 is disposed on the side of the two main body blocks 24 facing the installation crossbar 27. The first-stage inclined surface 25 is in close contact with the main inclined surface 13.

[0042] The top of the main block 24 is provided with a slot 28, and a second-level inclined surface 29 is provided on the side of the slot 28 away from the gap 30.

[0043] Based on the above, the arrangement of the first connecting block 21, the second connecting block 22, and the third connecting block 23 allows the expansion joint to be used in public environments such as bridges by setting different connecting blocks 2. Different connecting blocks can be replaced according to actual needs to meet different actual requirements. In this process, the connecting steel bar 15 is embedded in the cement, providing a stable support foundation for the connecting block 2, so that the connecting block 2 can effectively transfer the force to the main structure of the building when subjected to external impact.

[0044] By setting the installation crossbar 27 and connecting plate 26, the connecting block 2 can be inserted into the inclined groove 16 and the opening groove 14 to achieve initial connection. The first-stage inclined surface 25 cooperates with the main inclined surface 13 so that after the connecting block 2 is connected to the steel structure 1, the main inclined surface 13 provides support for the first-stage inclined surface 25. When the connecting block 2 is subjected to external impact, there is an inclined angle between the contact surface of the main inclined surface 13 and the first-stage inclined surface 25. Therefore, when the external force is applied to the contact surface, there will be two-way component forces, namely vertical and horizontal component forces, thereby reducing the load in one direction of the expansion joint and extending its service life. Since the connecting steel bar 15 firmly connects the steel structure 1 to the main building structure, these component forces can be transmitted to the main building structure through the steel structure 1 and borne by the entire main building structure, further improving the load-bearing capacity and impact resistance of the expansion joint.

[0045] like Figures 9-11 As shown, the mounting cover 3 includes a cover plate 31 disposed inside the mounting groove 12. The lower surface of the cover plate 31 is provided with a snap-fit ​​groove 32. A third-level inclined surface 33 is provided in the snap-fit ​​groove 32 on the side facing the connecting block 2. The third-level inclined surface 33 is in close contact with the main inclined surface 13.

[0046] The mounting cover 3 includes a cover plate 31 disposed inside the mounting groove 12. The lower surface of the cover plate 31 is provided with a snap-fit ​​groove 32. A third-level inclined surface 33 is provided in the snap-fit ​​groove 32 on the side facing the connecting block 2. The third-level inclined surface 33 is tightly fitted with the main inclined surface 13. The mounting cover 3 is connected to the steel structure 1 and the connecting block 2 simultaneously by screws.

[0047] An inclined locking block 34 extending into the inclined groove 16 is provided on the top wall of the locking groove 32. The lower surface of the inclined locking block 34 is in close contact with the circumferential surface of the mounting crossbar 27. A fourth secondary inclined surface 35 is provided on the opposite side of the two cover plates 31. The fourth secondary inclined surface 35 is in close contact with the second secondary inclined surface 29.

[0048] Based on the above, the mounting cover 3 is connected to both the steel structure 1 and the connecting block 2 by screws, thereby fixing the connecting block 2. The third-level inclined surface 33 and the fourth-level inclined surface 35 cooperate with the main inclined surface 13 and the second-level inclined surface 29 respectively, thereby converting the external force into two component forces in different directions, thus reducing the load of the external force on the expansion joint in a single direction.

[0049] The inclined locking block 34 and the inclined groove 16 cooperate to fix the installation crossbar 27.

[0050] In summary, the expansion joint, through the cooperation between the steel structure 1, the connecting block 2, and the mounting cover 3, allows the connecting block 2 to be disassembled and replaced. Furthermore, the three structures cooperate with each other, and the contact surfaces at the joints have an inclined angle. Therefore, when a vehicle passes over and applies an impact force to the expansion joint, the impact force is converted into two component forces, thereby reducing the burden caused by the impact force and extending the service life.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
