Abstract
The utility model relates to a tunnel evacuation platform and belongs to the technical field of road traffic ancillary facilities. The tunnel evacuation platform comprises a platform surface and a supporting structure. The supporting structure comprises a cross beam and a supporting beam. One end of the cross beam is fixed on a tunnel wall, and the other end of the cross beam is hung in the air. One end of the supporting beam is fixed on the tunnel wall, the other end of the supporting beam is fixed near the middle of the cross beam, and an included angle between the other end of the supporting beam and the cross beam is >= 40 degrees. By fully utilizing a cross section shape of a tunnel, the evacuation platform is reasonably fixed on the tunnel wall, and the beneficial effect that arrangement is compact and space is saved is achieved. As further improvement of the tunnel evacuation platform, at least one end of the supporting beam can be adjusted to meet requirements of installation adjustment on site and compensate structural error of the tunnel. The tunnel evacuation platform further comprises a handrail. The handrail is fixed on a position of the tunnel wall, the position is on half person height above the platform surface, and the handrail enables staff walking on the tunnel evacuation platform to be safe.
Description
Technical field
The utility model belongs to road traffic ancillary facility technical field, relates in particular in the closure communications and transportation place such as a kind of subway tunnel, is used for evacuating the evacuation platform that crowd or maintenance are used temporarily.
Background technology
Along with the development of society, subway becomes one of intensive public place of personnel gradually, because the metro operation environment is special; Safety problem particularly highlights; In case breaking out of fire or other accidents, passenger's emergency escape seem particularly important, owing to receive the interior personnel of subway many; The influence of factors such as interior escape condition difference of subway tunnel and escape time are short; Subway tunnel all must supportingly be provided with corresponding safety measure in the design-and-build process, in the tunnel, evacuation platform being installed is exactly one of effective measures.
At present; Widely used evacuation platform mainly is made up of table top and braced structures; Wherein the table top of platform be erected at a plurality of adjacent arrangements the braced structures crossbeam above, the basic structure of braced structures cross section is T font or I shape, adopts the braced structures of above-mentioned shape; The evacuation platform floor space is big, makes just very narrow originally tunnel space layout not compact.
The utility model content
To above-mentioned technical problem, the utility model provides the evacuation platform that a kind of floor space is little, make the tunnel space compact in design.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts does, a kind of evacuation platform comprises table top and braced structures, and said braced structures comprises crossbeam and brace summer, and said crossbeam one end is fixed on the tunnel wall, and the other end is unsettled; Said brace summer one end is fixed on the tunnel wall, and the other end is fixed near the middle part of said crossbeam, with said crossbeam angle >=40 °.
The utility model fully uses the shape of tunnel cross section, and evacuation platform reasonably is fixed on the tunnel wall, reaches the beneficial effect in compact in design, saving space.
As the further improvement of the utility model, at least one end scalable of said brace summer satisfies the on-the-spot needs that adjustment is installed, with the structural failure in compensation tunnel; Said evacuation platform comprises handrail, and said handrail is fixed on the tunnel wall of said table top top half people's eminence, and this handrail makes the personnel that walk on the evacuation platform safer.
Description of drawings
Fig. 1 is the utility model evacuation platform structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made and to be further specified.
As shown in the figure, the utility model evacuation platform comprises table top 1 and braced structures, and said braced structures comprises crossbeam 2 and brace summer 3, and said crossbeam one end is fixed on the tunnel wall 4, and the other end is unsettled; One end of said brace summer is fixed on the tunnel wall 4, and the other end is fixed near the middle part of said crossbeam 2, and with said crossbeam angle >=40 °, the preferred version angle is 45 °.Consider the structural failure of running tunnel, brace summer 3 must satisfy the on-the-spot adjustment needs of installing, and brace summer 3 at least one ends are the scalable end.
Running tunnel is under disaster environments such as fire, parking accident, and evacuation platform can guarantee that passenger safety evacuates, table top 1 or more highly the 2000mm scope be territory, personnel dispersion area, other system equipment can not be installed, cable etc.On the tunnel wall 4 of half people's eminence above table top 1, handrail 5 is set, for personnel's walking provides more safety guarantee.
The description of above embodiment is comparatively concrete, detailed; But can not therefore be interpreted as restriction to scope; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design; Can also make some distortion and improvement, these all belong to the protection domain of the utility model.
Claims (4)
1. an evacuation platform comprises table top and braced structures, it is characterized in that: said braced structures comprises crossbeam and brace summer, and said crossbeam one end is fixed on the tunnel wall, and the other end is unsettled; One end of said brace summer is fixed on the tunnel wall, and the other end is fixed near the middle part of said crossbeam, with said crossbeam angle >=40 °.
2. evacuation platform according to claim 1 is characterized in that: at least one end scalable of said brace summer.
3. evacuation platform according to claim 2 is characterized in that: said brace summer and crossbeam angle are 45 °.
