Abstract

The utility model relates to a stair with relatively strong fireproof performance, especially refers to a fast-assemble type fire-fighting outdoor evacuation stair, and the stair is suitable for fire-fighting reconstruction projects of various buildings. Structural features of the stair are that cartridge steel pipe connecting members are employed for connecting main support structures like pillars and cross beams, steel pipes forming the stair pillars and crossbeams are filled with water and are connected with a water tank through a water inlet and a pipeline, and crossbeams on a top of each stair platform are provided with fire-fighting nozzles; and a surface of the stair is provided with an antitheft net. The stair can be fast constructed in a construction site, large-scale engineering equipment is not needed, material cost, construction cost and time cost are reduced, the stair is provided with the antitheft net and an antitheft door, stealing is prevented, water is injected through a self-bring solar energy constant temperature water tank, so cooling water in the stair is not frozen, normal temperature can be kept under fire hazard high temperature, the stair is ensured no to fall under high temperature environment, the fire fighting nozzles can also automatically spray out water curtains for cooling, and reliable protection is timely provided for people in evacuation.

Description

The outdoor escape stair of fast assembling fire-fighting

Technical field

This Shi is with Xin Xing Wataru and a kind of stair with stronger fire-resistant function, and the outdoor escape stair of especially a kind of fast assembling fire-fighting is applicable to the fire-fighting improvement project of all kinds of buildings.

Background technology

At present a lot of civilian construction often run into the situation of escape stair lazy weight when changing use, can only build unclosed stair in outdoor adding.Common cement stairway or iron skill stair cost are high, long in time limit, and theftproof is relatively poor, and common iron skill escape stair carrying personnel amount is limited, when running into thermal-flame, and the danger of may collapsing, security reliability is not strong.

The utility model content

The purpose of this utility model is will provide a kind of to build fast; self is with safety grid, applicator, and effectively control personnel turnover prevents from stealing; stair structural integrity under hot environment does not collapse, for personnel in time evacuate the outdoor escape stair of fast assembling fire-fighting that reliably protecting is provided.

The technical scheme that the utility model Bian uses is:

The outdoor escape stair of a kind of fast assembling fire-fighting, comprise pillar of stair, crossbeam that steel pipe is formed by connecting, and be spaced a distance thereon and become landing with the steel member with Plate Welding with skeleton, set up stair step between adjacent two platforms, it is characterized in that: with the clamp-press type connector of steel tube, column, crossbeam main support structure are connected, consist of the interior water-filling of steel pipe of pillar of stair, crossbeam, connect water tank by water inlet, pipeline, on each landing upper beam, applicator is installed; The stair surface is provided with safety grid.

Water tank is established at the stair top.

Stair one floor platform access door is established security door.

these stair can not need fast construction in the situation of major works equipment at the construction field (site), reduce material, construction and time cost, stair self are with safety grid and security door, effectively control personnel turnover, prevent from stealing, and by carrying the water filling in pipeline of solar constant temperature water tank, cooling water in whole stair was not both frozen in winter, the stair overall structure can keep normal temperature again under high temperature of fire, guarantee that stair structural integrity under hot environment does not collapse, when propagation of flame near staristep the time, applicator can also spray the water curtain cooling automatically, for in time evacuating, personnel provide reliable protection.

The specific embodiment

The outdoor escape stair of fast assembling fire-fighting of the present utility model mainly is comprised of parts such as steel pipe 1, clamp-press type connector of steel tube 2, steel member 3, steel plate 4, safety grid 5, security door 6, water tank 7, awning 8, applicators 9.

Main steel pipe 1 material that adopts such as pillar of stair, crossbeam, use steel pipe commonly used 1 and clamp-press type connector of steel tube 2 to carry out combination collocation, clamp-press type connector of steel tube 2 can adopt cross etc., use bayonet socket or thread connecting mode to connect, form vertical type stair bracket frame construction, and be spaced a distance thereon and use steel member 3 and be welded into landing 11 with the steel plate 4 of skeleton.Set up stair step 10 between adjacent two platforms, welding handrail and railing on marking time are offered door opening access door are installed on the corresponding metope of each landing.The security door 6 of outwards opening is installed on the Stall support column, the stair top arranges awning 8 and water tank 7, water tank 7 can be made the solar constant temperature water tank, pass through water inlet 12 water fillings or artificial recharge by water supply pipe, and be connected by the main column of pipeline and stair, the inner water-filling state that keeps of pillar of stair crossbeam is equipped with applicator 9 on each landing 11 upper beam.The stair surface is provided with anti-theft steel wire net 5, one floor platforms except access door is provided with security door 6, and remainder is welded with iron sheet, plays antitheft and the fall arrest effect.

The outdoor escape stair of this fast assembling fire-fighting, respective beam, post, connecting tube, mark time, handrail is standard component and makes, and can use light erecting tools to carry out Fast Installation during installation, the daily common building escape stair that can be used as uses.When the door and window hole that closes on stair catches fire, landing, column etc. can be subject to high-temperature baking, but owing to existing a large amount of water as refrigerating medium in whole stair overall structure, can effectively keep stair overall structure temperature stabilization, the accident that reduces to collapse because of intensity can not occur, spread to landing as flame, the applicator that arranges of landing top ejection water curtain automatically, isolation flame keeps stair can constantly be in the state that can pass through.
