Description

TECHNICAL FIELD

[0001] The utility model belongs to tunnel construction equipment technical field, specifically a tunnel walkway board support. BACKGROUND

[0002] In the process of urban rail construction, first, a shield tunneling machine is used to excavate a subway tunnel, then a spliced pipe piece is fixedly arranged on the subway tunnel to fix the subway tunnel, and then construction is carried out inside the subway tunnel.

[0003] At this time, walkway boards need to be laid in the tunnel to facilitate the movement of construction personnel. Currently, in the industry, walkway board supports are usually arranged on the spliced pipe pieces, and then walkway boards are laid on the walkway board supports. There are many patent technologies related to this. For example, in the utility model patent with publication number CN216477465U, a walkway board support is disclosed, which comprises a horizontal cross beam, an inclined support rod, an arc-shaped support rod, a movable support plate and an adjusting bolt. By turning the adjusting bolt, the movable support plate can be rotated to adapt to tunnels of different diameters. However, when this walkway board support is installed, only the mounting lug plate is separately connected with the bolt of the pipe piece, which can easily lead to unstable connection. For another example, in the utility model patent with publication number CN218844371U, the walkway board structure comprises a construction platform and a fixing frame. The construction platform comprises a horizontal telescopic assembly, a protection assembly and a plurality of vertical telescopic assemblies. The horizontal telescopic assembly comprises a first telescopic plate, a second telescopic plate and a first adjusting piece. The vertical telescopic assembly comprises a first telescopic rod, a second telescopic rod, a second adjusting piece and a base. The vertical adjusting rod is provided with a plurality of third adjusting pieces. This walkway board structure is complex, inconvenient to operate and use, and has high production and processing costs.

[0004] Therefore, it is necessary to design a walkway board support structure that is simple in structure and firmly and reliably connected during installation. UTILITY MODEL CONTENTS

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] As Figures 1 to 7 shown in the utility model discloses a tunnel walkway plate support, comprising crossbeam 1, inclined support rod 2, vertical support rod 3, hook 4, crossbeam 1, inclined support rod 2 and vertical support rod 3 are connected between the head and tail, form a triangular structure.

[0029] Hook 4 is located at the outside of the triangular structure, and is connected with vertical support rod 3;On the side end of vertical support rod 3 close to crossbeam 1, there is mounting lug 5, and mounting hole 6 is formed in mounting lug 5;Hook 4 and mounting lug 5 are all towards the same side of the triangular structure.

[0030] Crossbeam 1, inclined support rod 2, vertical support rod 3 and hook 4 are all welded.

[0031] In addition, column insertion pipe sleeve 7 is vertically arranged on the side end of crossbeam 1 away from mounting lug 5, and the opening of column insertion pipe sleeve 7 faces the outside of the triangular structure. Column insertion pipe sleeve 7 can be used to insert guardrail column 12, which is convenient for installing guardrails.

[0032] The number of hooks 4 is multiple, and the multiple hooks 4 are arranged in parallel. In a specific embodiment, the number of hooks 4 is 2, and the hooks 4 are arranged in parallel on the outside of vertical support rod 3.

[0033] As Figure 3 shown, it is the installation structure schematic diagram of tunnel walkway plate support installed on the pipe piece 8 in the tunnel.

[0034] The pipe piece 8 in the tunnel is provided with pipe piece bolt 9, and the multiple pipe pieces 8 are spliced and connected, and there is splicing gap 10 between the pipe pieces 8. This is the conventional setting of the subway tunnel, and the tunnel walkway plate support is installed by using pipe piece bolt 9 and splicing gap 10.

[0035] Place the horizontal beam 1 of the tunnel walkway slab support horizontally, fit the mounting holes 6 on the mounting lugs 5 onto the segment bolts 9, and insert the hooks 4 into the splice gaps 10. At this point, the vertical support rods 3 and the bodies of the hooks 4 are tightly attached to the segment 8, thus completing the installation of the tunnel walkway slab support. After installation, guardrail posts 12 can be inserted into the post insert sleeves 7 for installing guardrails.

[0036] like Figure 4 and 5 The diagram shows the longitudinal structure of the tunnel segment 8 and the tunnel walkway slab support after installation. Multiple tunnel walkway slab supports are continuously installed between multiple tunnel segments 8, and then walkway slabs 11 are laid between the tunnel walkway slabs. The walkway slabs 11 are laid above the crossbeam 1 to facilitate the movement of construction personnel.

[0037] like Figure 6 and 7 The diagram shows the transverse structure of the tunnel segment 8 and the tunnel walkway slab support after installation. The tunnel walkway slab support and the tunnel segment 8 are fixedly connected by installing lugs 5 and hooks 4. The walkway slab 11 is laid on the crossbeam 1.

[0038] Once the construction of this section of the subway tunnel is completed, the tunnel walkway slab support can be directly pried open to tilt it, and then the tunnel walkway slab support can be removed from the tunnel segment 8. Installation and disassembly are convenient.

[0039] In this utility model, tunnel walkway slab supports are continuously installed along the splicing gaps 10 of multiple tunnel segments 8. Therefore, the distance between every two tunnel walkway slab supports is the same, that is, the length of the guardrail and walkway slab 11 set above the tunnel walkway slab supports is also the same, which facilitates transportation and has strong adaptability, thus greatly improving practicality.
