Technical field
The utility model relates to a kind of composite material evacuation platform, relates in particular to high stable structure high flame retardant composite material evacuation platform for a kind of urban track traffic.
Background technology
Expansion along with China's expanding economy and city size, urban rail transit construction has become the key project of nation-building, the advantages such as it is large with freight volume, speed is fast, safe and reliable, environment pollution is little, become and alleviate China city and Intercity Transportation demand and reduce one of means of a kind of effective means of polluting.
The urban track traffic personnel are intensive, once breaking out of fire or other accidents, whether the passenger can emergency escape be exactly the urgent major issues that solve of needs.At present, in subway tunnel design-and-build process, just comprise in supporting safety measure passenger's life-saving evacuation platform is set.Due to humid environment in subway tunnel, limited space, therefore, just require evacuation platform not only enough mechanical strengths will be arranged, and also will possess good fire prevention, protection against the tide, anticorrosion, electrical insulating property and long-life, is convenient to installation simultaneously, non-maintaining.
In current subway tunnel, the polymer matrix composites evacuation platform of use, its glass fiber content is low, and fire resistance is poor, and its form of structure mainly is comprised of by corresponding metal connecting piece parts such as crossbeam, cant beam and landing slabs.Wherein landing slab mostly is I shape, duplexing font or ∏ type etc., by connecting rod, is assembled into together.Landing slab is by connectors such as U-shaped card or T-shaped cards and be bolted on crossbeam.After the landing slab assembling, there is gap in centre, and is uneven, and after especially installing the U-shaped card or T-shaped card that is connected use with crossbeam, landing slab plate face is obviously rough and uneven in surface especially; In addition, on crossbeam, hole, can reduce the support strength of crossbeam, these are all the potential safety hazards existed at present.Especially when accident occurs, the passenger escapes chaotic crowded, is easy to cause personnel (Ms who the especially wears high heels) pin of rivering bend even to fall, once and the crossbeam after boring is long service time, after aging, also very likely can be in the escape, the total collapse accident appears in landing slab.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in prior art.
The utility model content
The purpose of this utility model is to provide a kind of composite material evacuation platform, solved existing urban track traffic low by the fire resistance of polymer matrix composites evacuation platform, the out-of-flatness of landing slab face, gap is large, and assembling boring causes the safe problems of impact such as reduction of beam strength.
The technical solution adopted in the utility model is:
A kind of composite material evacuation platform, comprise crossbeam, cant beam peace bedplate surface, described beam-end is fixed on tunnel wall by crossbeam tunnel connector, described cant beam bottom is fixed on tunnel wall by cant beam tunnel connector, the crossbeam middle part is fixed in by the transverse oblique beam connector in described cant beam top, be provided with the cant beam steering head between described cant beam and transverse oblique beam connector, described landing slab face is located on crossbeam, it is characterized in that: described landing slab face is combined by a plurality of platform bars and three type connecting rods, described landing slab face is fixed on crossbeam by platform crossbeam connector.
The left and right sides of described platform bar lower end extends internally respectively and forms extension, and the length of described extension is less than 1/2 of face width total length above the platform bar, between the two sides of the extended surface of described extension and platform bar, is arc transition.
Described crossbeam tunnel connector, cant beam tunnel connector and transverse oblique beam connector are the stainless steel connector, and described platform crossbeam connector is stainless steel band or Plastic Bandage.
Described crossbeam, platform bar, three type connecting rods and cant beam adopt phenolic aldehyde base glass fibre reinforced composite material to be made by pultrude process.
The utility model has the advantages that: product producing process is stable, and there is high flame retardant, low heat value, the performance such as corrosion-resistant, electrical insulating property is good; Products machinery intensity is high, and the landing slab face is smooth, escapes safer; Do not destroy beam structure, improved greatly the application life of product.
