Abstract
The invention relates to a ventilating waterproof structure of a prefabricated cabin. The ventilating waterproof structure of the prefabricated cabin comprises a cabin body with a top frame and a top cover supported on the top frame. The top cover comprises a top plate, a strip-shaped ventilating waterproof piece is arranged at the bottom of the top cover, the ventilating waterproof piece is provided with a vertical flange connected with the top plate and a cross flange connected with the cabin body, the cross flange faces the inner side of the prefabricated cabin, the cross flange and the vertical flange are arranged in an L shape, ventilating holes are formed in the cross flange, and the height of the cross flange is smaller than that of the top face of the top frame. The vertical flange can achieve the function of preventing rain and snow water from entering the prefabricated cabin, and even though part of the rain and snow water flows to the cross flange along the ventilating waterproof piece, the rain and snow water cannot enter the prefabricated cabin due to the fact that the height of the cross flange is smaller than that of the top face of the top frame. The ventilating holes in the cross flange can enable the internal space of the top cover to be kept communicated with the outside, the function of ventilation can be achieved, the function of isolation can be achieved, and therefore the aim of ventilation and waterproofness is achieved.
Description
Technical field
The present invention relates to prefabricated cabin air-penetrable waterproof structure.
Background technology
Along with the high speed development of power industry, prefabricated cabin owing to being convenient to transport, floor space is little, operating cost is low, short construction period, the advantage such as non-maintaining, in the construction being more and more widely used in transformer station and improvement project, becoming an important component part of standard dispensing formula transformer station, is the update product of original secondary device room.In the prior art, because preset cabin bulk strength considered by needs, the top cover of general prefabricated cabin, column, base are all welded together with guaranteed strength.And it is comparatively large to weld rear deck body size, cause difficulty to transport, also often can run into superelevation and situation about cannot pass through.In some mountain areas, because of road steeper, the restriction cabin body size having exceeded some traffic conditions just makes transport become dangerous, has a strong impact on the life security of personnel.
Application number is 201420350811.X, the Chinese patent of Authorization Notice No. CN 203977917 U discloses a kind of dispensing formula transformer station prefabricated cabin with compound roof, comprise cabin body support frame and be arranged on the top cover on the body support frame of cabin, top cover comprise for the formation of skeleton truss and cover top board on truss, truss and cabin body support frame connect as one and adjustable height, effectively can avoid the transportation problem brought because of superelevation in transportation.Meanwhile, the edge of the top cover of above-mentioned prefabricated cabin is also provided with the rhone that panel beating bending is made, and rhone, together with top board bolt, can avoid rainwater to flow in prefabricated cabin along top cover edge; Top board two ends also offer ventilation opening, for ventilating.
But the ventilation opening of existing prefabricated cabin is arranged on top, cabin, easily affects structural strength, not easily manufacture and can bring a waterproof difficult problem.In addition, in order to solve transportation problem in prior art, when meeting cabin body bulk strength, the prefabricated cabin of split-type is arisen at the historic moment, this prefabricated cabin comprises the cabin body with top frame and the top cover be supported in top frame, and the top board due to top cover needs to assemble with the skeleton in top cover, and skeleton is generally be supported in the top frame of cabin body, therefore the inner space of top cover directly can communicate with the external world, there is the problem that waterproof requirement not easily realizes.
Summary of the invention
The object of this invention is to provide a kind of prefabricated cabin air-penetrable waterproof structure, to solve the problem that prefabricated cabin structure of the prior art cannot meet air permeable waterproof requirement.
