Abstract

The utility model relates to a quick drainage system for an external stairway, comprising a drainage ditch, a drainage groove, a floor drain, and a drainage standing pipe, all of which are disposed at the side end portion of a stairway tread and a rest platform, wherein the stairway tread and the rest platform is sloped towards the drainage ditch, the drainage ditch is sloped towards the drainage groove, the floor drain is arranged in the drainage groove, and the water outlet end of the floor drain is in communication with the drainage standing pipe. By using the above-mentioned drainage system, the unorganized drainage in the conventional external stairway becomes organized drainage, and rain water can be drained away quickly, which facilitates safe passage of passengers. The quick drainage system can be widely applies to the organized drainage of an open ramp and the external stairway.

Description

The quick drainage system of outdoor staircase

Technical field

The utility model relates to the drainage system of a kind of drainage system, particularly a kind of outdoor staircase.

Background technology

People's Bank of China or garage ramp, open type overpass all are requisite auxiliary traffic measures in the urban traffic, and the open type that present China generally adopts is not generally taked drainage measure, and ponding freely drains into the road surface on it.The draining of this kind inorganization exists, and the one,, in case meet sleety weather; Serious seeping phenomenon can take place in the stair tread, influences the current safely and fast of pedestrian, and the 2nd; The free draining of overpass stair; May splash under the bridge or pedestrian that the bridge limit is current and vehicle on, cause unnecessary trip trouble, therefore need design can be fast effectively the outer drainage system of drip chamber be ten minutes necessity.

The utility model content

The purpose of the utility model provides the quick drainage system of a kind of outdoor staircase; The draining that solves existing outdoor staircase is the inorganization draining; Run into the bigger situation of displacement, cause the wet and slippery technical problem in stair step surface because ponding can't in time be drained.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

The quick drainage system of a kind of outdoor staircase; Comprise the gutter, rhone, floor drain and the soil stack that are arranged on stair tread and half space side end; Said stair tread and the equal aspect of half space gutter, said gutter aspect rhone, said rhone is arranged on the side end of half space; Be provided with floor drain in it, the water side of said floor drain is communicated with soil stack.

Said floor drain end face is stamped the rainwater double-edged fine-toothed comb.

Said rainwater double-edged fine-toothed comb is iron double-edged fine-toothed comb, stainless steel double-edged fine-toothed comb or resin double-edged fine-toothed comb.

The gradient in said stair tread, half space and gutter is not less than 2%.

The width in said gutter is not less than 100mm, and the degree of depth is 50～100 mm.

The width of said rhone is greater than 300mm.

Compared with prior art the utlity model has following characteristics and beneficial effect:

Through the drainage system of being made up of weathering, rhone, drain and soil stack is set, drain fast the water on stair bench and the half space is organized, be convenient to the pedestrian and fast and safely pass through.

The utility model draining approach is simple and clear, and the drainage measure of taking is simple, but the People's Bank of China that extensive use is opened wide or garage ramp, overpass stair etc. have very strong versatility.

The draining in a organized way of ramp that the utility model can be widely used in opening wide and outdoor staircase.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further detailed explanation.

Fig. 1 is a vertical view of the present invention.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the B-B sectional view of Fig. 1.

Reference numeral: 1-gutter, 2-rhone, 3-floor drain, 4-soil stack, 5-rainwater double-edged fine-toothed comb, 6-stair step, 6.1-mark time surface layer, 6.2-mark time deck, 7-half space, 7.1-platform surface layer, 7.2-platform structure layer.

The specific embodiment

Embodiment is extremely shown in Figure 3 referring to Fig. 1; The quick drainage system of a kind of outdoor staircase comprises the gutter 1, rhone 2, floor drain 3 and the soil stack 4 that are arranged on stair tread 6 and half space 7 side ends, said stair tread 6 and half space 7 equal aspect gutters 1; Said gutter 1 aspect rhone 2; Said rhone 2 is arranged on the side end of half space 7, is provided with floor drain 3 in it, and the water side of said floor drain 3 is communicated with soil stack 4.

Said floor drain 3 end faces are stamped rainwater double-edged fine-toothed comb 5.

Said rainwater double-edged fine-toothed comb 5 is iron double-edged fine-toothed comb, stainless steel double-edged fine-toothed comb or resin double-edged fine-toothed comb.

The gradient in said stair tread 6, half space 7 and gutter 1 is not less than 2%.

The width in said gutter 1 is not less than 100mm, and the degree of depth is 50～100 mm.

The width of said rhone 2 is greater than 300mm.

The gradient of said stair step 6 and half space 7 is generally formed with flat upper surface layer 7.1 by the surface layer 6.1 of marking time respectively.When stairway width is excessive, also can form with platform deck 7.2 by the deck 6.2 of marking time respectively.
