Embodiment 1

[0039] Such as Figure 1-5 As shown, a 90° steel ladder 2 is set on one side of the escape hole 3 in the interlayer of the comprehensive pipe gallery, and guardrails 4 are set directly behind the 90° steel ladder 2 and outside the escape hole 3 on both sides. The handrail 1 is arranged on the outer side of the interlayer escape opening 3 and is parallel to the 90° steel ladder 2 .

[0040] Such as figure 2 , image 3 As shown, the handrail 1 is composed of a column 7, a crosspiece 6 and a connecting piece 8. The column 7 is integrally formed into a hollow tubular handrail outer frame, and the middle part is welded in parallel to a plurality of crosspieces parallel to the roof of the pipe gallery. 6. The bottom is fixed to the roof 5 of the pipe gallery through the connecting piece 8. The upper part of the connector 8 is a slot 9, and the lower part is a bottom plate 11, and the side of the slot 9 and the inner bottom surface of the bottom plate 11 are respectively provided...

Embodiment 2

[0042] Such as Figure 6 As shown, as a further technical solution of the present invention, for the escape opening that needs to be separated by fire protection, the interlayer escape opening 3 can be opened into a circular hole and an airtight fireproof cover is provided, and the side below the escape opening 3 is provided with the 90 ° steel ladder 2, the handrail 1 is arranged on the periphery of the hole above the escape hole 3 and parallel to it above the 90 ° steel ladder 2; the hinged end of the fireproof cover plate is installed on the above escape hole 3 The handrail is opposite to and opened upwards; the handrail is installed outside the edge of the fireproof cover.

Abstract

The invention discloses an escape exit of a comprehensive pipe gallery interlayer. The escape exit comprises an escape hole formed in a pipe gallery top plate in the comprehensive pipe gallery interlayer and a 90-degree steel crawling ladder. The escape exit is characterized in that the 90-degree steel crawling ladder 2 is arranged on one side below the escape hole 3, and guardrails 4 are arranged on the periphery of the hole above the escape hole and on the pipe gallery top plate right behind the 90-degree steel crawling ladder 2 and on the two sides of the 90-degree steel crawling ladder 2; handrails 1 are arranged on the periphery of the hole above the escape hole 3 and right in front of the 90-degree steel crawling ladder 2 and are fixed to the pipe gallery top plate; and the handrails are provided with horizontal crosspieces, escape personnel hold the handrails with hands to transit to the pipe gallery interlayer from the two sides of the crawling ladder, and safety and convenience are achieved. The installation process of the handrails is simple and rapid, rapid disassembly and assembly can be achieved in the later period, the defect that integrated handrails are difficult to maintain is avoided, and therefore the integrity of the functionality of the handrails is guaranteed. For the escape exit needing to adopt fireproof separation, the handrails do not affect opening and closing of a fireproof cover plate.

Description

technical field [0001] The invention belongs to the technical field of comprehensive pipe gallery, and specifically provides an escape opening for an interlayer of comprehensive pipe gallery. Background technique [0002] The current common method for the escape exit of the mezzanine of the comprehensive pipe gallery is to set up a 90° steel ladder on the side of the escape hole, but there is a lack of handrails for the escape personnel to transition from the 90° steel ladder to the interlayer, which reduces the safety of the escape personnel. efficiency, so it needs to be solved urgently. Contents of the invention [0003] In view of the above problems, the present invention provides an escape exit for the interlayer of the integrated pipe gallery, which aims to solve the problem of escape from the interlayer escape opening of the integrated pipe gallery, and ensure that escape personnel can escape from the cabin of the pipe gallery to the interlayer safely and convenient...
