Problems solved by technology

[0005] In some subway lines, due to the space limitation caused by other equipment in the tunnel, the cable support can only be installed on one side of the evacuation platform, and in order to ensure the safety of personnel evacuation, it can only be installed under the evacuation platform
However, the height of the evacuation platform from the ballast bed surface is usually limited. In order to install the evacuation platform and the cable support at the same time, the installation height and size of the evacuation platform and the cable support are often reduced, which will damage the mechanical strength of the evacuation platform or reduce the bearing space of the cable support. , causing inconvenience to the design, construction and use of evacuation platforms and cable supports

Embodiment 1

[0036] Specifically, such as Figure 1~6 As shown, a kind of evacuation platform that can fix cable support, described evacuation platform 2 comprises platform panel 21 and platform support 22, and described platform support 22 comprises crossbeam 4 and support beam 5, and described crossbeam 4 is installed in the tunnel along the horizontal direction On the wall 1 , the platform panel 21 is located on the beam 4 , the support beam 5 is supported on the lower side of the beam 4 , and the cable support 3 is arranged on the support beam 5 .

[0037] Compared with the prior art, the present application realizes the ingenious use of space by setting the cable bracket 3 on the support beam 5. On the one hand, the cable The support 3 is installed on the support beam 5, which ensures that the mechanical strength of the evacuation platform 2 is not reduced; on the other hand, the cable support 3 is arranged on the support beam 5 below the platform panel 21, so that the bearing space o...

Embodiment 2

[0042]In order to further optimize the structure of the evacuation platform that can fix the cable support described in Embodiment 1, under the premise of not reducing the mechanical strength of the evacuation platform or reducing the bearing space of the cable support, the installation of the evacuation platform and the cable support is realized. The design, construction and use of the support provide convenience. On the basis of Embodiment 1, the structure of the evacuation platform that can fix the cable support described in Embodiment 1 is further optimized, specifically:

[0043] Such as figure 1 As shown, the tunnel wall 1 is arc-shaped, the evacuation platform 2 is installed on the tunnel wall 1, the beam 4 is arranged along the horizontal direction, and the support beam 5 is supported obliquely on the lower side of the beam 4, One end of the support beam 5 is connected to the crossbeam 4 through a connector 7; the other end of the support beam 5 is connected to the tun...

Embodiment 3

[0045] In order to further optimize the structure of the evacuation platform that can fix the cable support described in Embodiment 1, under the premise of not reducing the mechanical strength of the evacuation platform or reducing the bearing space of the cable support, the installation of the evacuation platform and the cable support is realized. The design, construction and use of the support provide convenience. On the basis of Embodiment 1, the structure of the evacuation platform that can fix the cable support described in Embodiment 1 is further optimized, specifically:

[0046] Such as figure 2 As shown, the tunnel wall 1 is a vertically arranged side wall, the evacuation platform 2 is installed between the tunnel wall 1 and the ballast bed surface 10, the crossbeam 4 is arranged along the horizontal direction, and the support beam 5 is vertically arranged. Supported directly on the lower side of the crossbeam 4, one end of the crossbeam 4 is vertically connected to t...

Abstract

The invention provides an evacuation platform capable of fixing a cable support. The evacuation platform comprises a platform panel and a platform support, wherein the platform support comprises a cross beam and a support beam; the cross beam is installed on the wall of a tunnel in the horizontal direction; the platform panel is located on the cross beam; the support beam is supported at the lowerside of the cross beam; and the cable support is arranged on the support beam. The evacuation platform capable of fixing the cable support realizes convenient installation for the evacuation platformand the cable support on the premise of not reducing the mechanical strength of the evacuation platform or reducing a bearing space for the cable support, and optimizes a connection structure for thesupport beam and a back plate, so that the cable support can be stably and reliably installed on the support beam.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an evacuation platform, in particular to an evacuation platform capable of fixing cable supports. Background technique [0002] At present, in subway tunnels, it is usually necessary to build a fire-fighting evacuation platform for emergency escape of passengers in the event of a fire or other emergencies. Generally, the evacuation platform is made of concrete, cement-based or composite materials, among which the composite material evacuation platform is made of continuous glass fiber reinforced phenolic resin, which has high mechanical strength, good fire resistance and excellent corrosion resistance. , electrical insulation and long service life, has been widely used. [0003] In addition, there are often cable racks for supporting cables in tunnels. Generally, its material is often steel or composite material, and it is usually fixed on the tunnel wall. Usually, the cab...
