Description

Technical Field

[0001] The utility model relates to the technical field of shield tunnels in urban rail transit, and particularly relates to a stainless steel fixing part structure capable of fixing a handrail at a single point. Background Technique

[0002] All kinds of brackets and handrails will be arranged in the shield tunnel of urban rail transit. In order to solve the adverse effects of drilling and installing anchor bolts on the shield tunnel, the embedded sleeve scheme is currently widely promoted in many places for shield tunnels, in order to reserve installation points on the tunnel segments for subsequent installation of various equipment and facilities. This kind of embedded technology usually involves reserving specific holes or grooves during the production process of tunnel segments for fixing brackets, cables, water pipes, communication lines, etc.

[0003] However, the current point-type embedded structure has only one anchoring point for fixing the evacuation platform handrail, while generally two anchoring points are required for fixing and installing the handrail, resulting in the other anchoring point can only be fixed by anchor bolts, thus damaging the tunnel structure, increasing the construction procedures and project investment, and being inconvenient for prefabrication and quick installation. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art in the above background technique, the purpose of the utility model is to provide a stainless steel fixing part structure capable of fixing a handrail at a single point, which perfectly solves a series of problems existing in fixing the handrail in the embedded sleeve scheme of the shield tunnel, and at the same time can also reduce the anchoring points of the traditional anchor bolt fixing scheme, further reducing the impact on the shield tunnel.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A stainless steel fixing part structure capable of fixing a handrail at a single point, including an L-shaped mounting plate, reinforcing ribs are arranged on the L-shaped mounting plate, the horizontal plate of the L-shaped mounting plate is fixedly connected with the fixing part through a connecting part, a handrail pipe is arranged inside the fixing part, and the vertical plate of the L-shaped mounting plate is fixed on the sectional pipe segment.

[0007] As a further scheme of the utility model, a groove-shaped fixing hole is opened at the connection between the vertical plate of the L-shaped mounting plate and the sectional pipe segment, and the vertical plate of the L-shaped mounting plate is fixedly connected with the sectional pipe segment through a fixing bolt passing through the groove-shaped fixing hole.

[0008] As a further scheme of the utility model, screw reserved holes are opened on the fixing part, and the fixing part is fixedly connected with the handrail pipe through fixing screws passing through the screw reserved holes.

[0009] As a further scheme of the utility model, fastening bolt reserved holes are opened on one side of the fixing part close to the horizontal plate of the L-shaped mounting plate, and the fixing part fixes the handrail pipe through a fastening bolt passing through the fastening bolt reserved holes.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] (1) Through the arrangement of a series of devices such as reinforcing ribs, fixing members, armrest tubes, and grooved fixing holes, the present utility model only needs one fixing point for fixation. The armrest structure can be fixed through a single anchoring point, perfectly solving a series of problems existing in the fixation of the armrest in the shield tunnel embedded sleeve scheme.
