Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a lining structure. Background Art

[0002] In bridge construction, adjacent members are usually connected by welding, which requires opening a welding groove in the butt ring area to facilitate welding. Since the butt weld is required to be a full penetration weld, root cleaning and welding are required on the other side of the weld. Generally, a temporary manhole is opened at the end of the member to facilitate the entry of welding personnel. The temporary manhole is sealed after the main weld is completed. However, for small-sized members (such as members with a cross-sectional width and height of less than 100 mm), the operating space is limited and the operation is difficult for operators, resulting in a significant reduction in the welding efficiency of small-sized members. Utility Model Content

[0003] The problem solved by the utility model is how to improve the welding efficiency of small-sized rods.

[0004] In order to solve the above problems, the utility model provides a liner structure.

[0005] In the first aspect, the utility model provides a gasket structure, including an annular gasket and a handle, wherein the annular gasket is used to be arranged inside a rod and coaxially with the rod, the outer diameter of the annular gasket is less than or equal to the inner diameter of the rod, the annular gasket includes an interconnected circular ring body and a protrusion, the protrusion extends along the axial direction of the annular gasket, a slot is provided on the rod, and the handle is used to pass through the slot and be detachably connected to the protrusion.

[0006] Optionally, a threaded hole is provided on the protruding portion, and one end of the handle is provided with a thread adapted to the threaded hole.

[0007] Optionally, the annular gasket further includes a first reinforcing rib, which is arranged between the inner walls of the annular body.

[0008] Optionally, the first reinforcing rib passes through the center of the annular body.

[0009] Optionally, a plurality of the first reinforcing ribs are provided.

[0010] Optionally, the annular gasket further includes a second reinforcing rib, one end of the second reinforcing rib is connected to the protrusion, and the other end is connected to the first reinforcing rib.

[0011] Optionally, a plurality of the second reinforcing ribs are provided.

[0012] Optionally, the annular gasket has a thickness ranging from 4 to 8 mm.

[0013] Optionally, the protrusion is a rectangular plate-shaped structure.

[0014] Optionally, a reinforcement structure is provided at the connection between the protrusion and the annular body.

[0015] The beneficial effects of the gasket structure of the present invention are as follows: when in use, the outer diameter of the annular gasket is less than or equal to the inner diameter of the rod, which facilitates the movement of the annular gasket in the rod, and the annular gasket is moved to the inner wall of the end of the rod to be docked, so that the outer wall of its circular ring body at least partially contacts the inner wall of the rod to be docked, and the rod with the slot is moved to the docking position, so that the inner wall of the rod with the slot contacts the outer wall of its circular ring body, and the slot is set corresponding to the protrusion extending along the axial direction of the annular gasket, and the handle is passed through the slot to contact the protrusion. The rod is connected by moving the handle to drive the annular gasket to move inside the rod. When it moves to the target position (for example, the annular seam where two rods meet), the annular seam of the rod is welded. After the handle is removed, the notch on the rod is welded. The whole process is simple to operate and has low requirements for operating space. Rod welding can be achieved outside the rod, which effectively improves the welding efficiency of small-size rods. At the same time, the handle is detachably set on the protrusion to achieve reuse of the handle, saving construction resources. The protrusion can also be used as a repair welding for the notch opened on the rod, saving welding resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In response to the problems existing in the above-mentioned related technologies, this embodiment provides a pad structure.

[0025] like Figure 1 As shown, a gasket structure provided by an embodiment of the present invention includes an annular gasket 1 and a handle 2. The annular gasket 1 is used to be arranged inside a rod 3 and coaxially arranged with the rod 3. The outer diameter of the annular gasket 1 is less than or equal to the inner diameter of the rod 3. For example, the outer diameter of the annular gasket 1 is 2 mm less than the inner diameter of the rod 3. The annular gasket 1 includes a circular ring body 11 and a protrusion 12 connected to each other. The protrusion 12 extends along the axial direction of the annular gasket 1. A notch 31 (such as Figure 2 As shown), the handle 2 is used to pass through the slot 31 and be detachably connected to the protrusion 12.

[0026] Specifically, the gasket structure disclosed in the present invention is applied to the circumferential seam welding of the rod 3. It should be noted that the material of the annular gasket 1 is the same as that of the rod 3, and the outer diameter of the annular gasket 1 is less than or equal to the inner diameter of the rod 3, so as to ensure that the annular gasket 1 moves within the rod 3 and avoid misalignment when the rods 3 are docked, which would make the gasket unable to be moved and installed.

[0027] When this embodiment is used, Figure 2 As shown, the outer diameter of the annular gasket 1 is less than or equal to the inner diameter of the rod 3, which facilitates the movement of the annular gasket 1 in the rod 3. The annular gasket 1 is moved to the inner wall of the end of the rod 3 to be docked, so that the outer wall of its circular ring body 11 at least partially contacts the inner wall of the rod 3 to be docked. The rod 3 with the notch 31 is moved to the docking position, so that the inner wall of the rod 3 with the notch 31 contacts the outer wall of its circular ring body 11, and the notch 31 is set corresponding to the protrusion 12 extending along the axial direction of the annular gasket 1. The handle 2 is passed through the notch 31 and connected to the protrusion 12. Move the handle 2 to drive the annular gasket 1 to move inside the rod 3. When it moves to the target position (for example, the annular seam where two rods 3 meet), the annular seam of the rod 3 is welded. After the handle 2 is removed, the notch 31 on the rod 3 is welded. The whole process is simple to operate and has low requirements for operating space. The rod 3 can be welded outside the rod 3, effectively improving the welding efficiency of small-sized rods 3. At the same time, the handle 2 is detachably set on the protrusion 12 to achieve the reuse of the handle 2 and save construction resources. The protrusion 12 can also be used as a repair welding for the notch 31 opened on the rod 3, saving welding resources.

[0028] Optionally, a threaded hole is formed on the protrusion 12, and one end of the handle 2 is provided with a thread adapted to the threaded hole, for being threadedly connected to the protrusion 12 through the threaded hole. The threaded hole enables the handle 2 to be connected to the protrusion 12 in the annular gasket 1, so that after the annular gasket 1 is installed, the handle 2 can be removed and the next annular gasket 1 can be installed, thereby realizing the reuse of the handle 2.

[0029] Optionally, the annular gasket 1 further includes a first reinforcing rib, which is arranged between the inner walls of the annular body 11 .

[0030] Specifically, the position of the first reinforcing rib can be set according to the actual installation situation. Figure 3 Due to the characteristics of the annular structure, optionally, in this embodiment, the first reinforcing rib is set through the center of the annular body 11, as shown in FIG. Figure 1 As shown in , the annular gasket 1 is strengthened to prevent the circular ring body 11 in the annular gasket 1 from deforming during movement, thereby improving the structural stability of the annular gasket 1.

[0031] Optionally, a plurality of the first reinforcing ribs are provided to reinforce the annular gasket 1 in multiple directions.

[0032] Alternatively, as Figure 1 As shown, the annular gasket 1 also includes a second reinforcing rib 5, one end of the second reinforcing rib 5 is connected to the protrusion 12, and the other end is connected to the center point of the first reinforcing rib to support and reinforce the protrusion 12, prevent the protrusion 12 from deforming during movement, and improve the structural stability of the annular gasket 1.

[0033] Optionally, a plurality of second reinforcing ribs 5 are provided to further reinforce the protruding portion 12 .

[0034] Optionally, the thickness of the annular gasket 1 is in the range of 4-8 mm.

[0035] The thickness of the annular gasket 1 in this embodiment is preferably 6 mm, which provides optimal support strength and is suitable for various small-sized rods 3 (e.g., a rod 3 with a cross-sectional width and height of 100 mm or a rod 3 with a cross-sectional width and height of 60 mm). In addition, the thickness can be adjusted according to actual conditions (e.g., the weight of the annular gasket 1), and this embodiment does not limit this.

[0036] Optionally, the protrusion 12 is a rectangular plate-shaped structure.

[0037] Optionally, a reinforcement structure is provided at the connection between the protrusion 12 and the annular body 11 to enhance the connection strength between the protrusion 12 and the annular body 11 and avoid deformation or breakage when the annular gasket 1 is moved.

[0038] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
