Description
Technical field
The present invention relates to prefabricated cabin air-penetrable waterproof structure.
Background technology
With the high speed development of power industry, prefabricated cabin is due to being readily transported, floor space is small, operating cost is low, construction
The advantages that cycle is short, non-maintaining, in more and more extensive construction and improvement project applied to transformer station, turns into standard dispatching formula and become
One important component in power station, it is the update product of original secondary device room.Conventionally, as need to consider
Preset cabin bulk strength, top cover, column, the base of general prefabricated cabin are each welded to together with proof strength.And nacelle after welding
Size is larger, and difficulty, the situation that is also frequently encountered superelevation and can not pass through are caused to transport.In some mountain areas, because of road
Steeper, the limitation nacelle size for having exceeded some traffic conditions allow for transport and become dangerous, have a strong impact on personnel's
Life security.
Application No. 201420350811.X, the U of Authorization Notice No. CN 203977917 Chinese patent disclose one kind
Dispatching formula transformer station prefabricated cabin with compound roof, including nacelle support and the top cover on nacelle support, top cover bag
The truss for forming skeleton and the top plate being covered on truss are included, truss connects as one with nacelle support and can adjust height
Degree, can effectively avoid the transportation problem brought in transportation because of superelevation.Meanwhile the edge of the top cover of above-mentioned prefabricated cabin
Place is additionally provided with rhone made of metal plate bending, and rhone is bolted together with top plate, and rainwater can be avoided to be flowed along tip cap edge edge
Enter in prefabricated cabin；Top plate both ends are further opened with ventilating opening, for divulging information.
But the ventilating opening of existing prefabricated cabin is arranged on cabin top, structural strength is easily influenceed, is not easy to manufacture and understands band
Carry out waterproof problem.In addition, in the prior art in order to solve transportation problem, in the case where meeting nacelle bulk strength, split-type
Prefabricated cabin arise at the historic moment, the prefabricated cabin includes nacelle and the top cover that is supported in top frame with top frame, due to
The top plate of top cover needs to be assembled with the skeleton in top cover, and skeleton is usually to be supported in the top frame of nacelle, therefore
The inner space of top cover can directly communicate with the external world, the problem of waterproof requirement is not easy to realize be present.
The content of the invention
It is an object of the invention to provide a kind of prefabricated cabin air-penetrable waterproof structure, to solve prefabricated cabin structure of the prior art
The problem of air permeable waterproof requirement can not be met.
The technical scheme of prefabricated cabin air-penetrable waterproof structure use is in the present invention：Prefabricated cabin air-penetrable waterproof structure, including tool
There are the nacelle of top frame and the top cover being supported in the top frame, the top cover includes top plate, the bottom of the top cover
Air permeable waterproof part provided with strip, the air permeable waterproof part have the vertical flanging that is connected with the top plate and with the nacelle
The lateral flap of connection, the lateral flap towards on the inside of prefabricated cabin and with the L-shaped setting of vertical flanging, in the lateral flap
Height provided with air-vent and lateral flap is less than the top surface of top frame.
The sealing for coordinating with top plate seal that extension on the inside of prefabricated cabin is provided with the top of the vertical flanging is rolled over
Side.
The top plate has a plastic sandwich, and the end face outside of the plastic sandwich is provided with for the sealing flanging insertion and close
Seal the flanging inserting groove coordinated.
The prefabricated cabin air-penetrable waterproof structure is Z-shaped flashing plate also including cross section, and flashing plate includes being used for and top plate
End face outside close fit riser portion, be arranged at the top of riser portion and towards the upper clinch of bending on the inside of prefabricated cabin
Point and be arranged on riser portion bottom and towards the lower overlap of bending on the outside of prefabricated cabin
The top surface of the top plate is convex-concave structure, and the riser portion is provided with the recess pair being used for the convex-concave structure
The apopore answered.
The apopore is the spaced long apopore of length direction along air permeable waterproof part, and the long apopore is provided with
Along more than two rows of the width laid out in parallel of riser portion.
The vertical flanging is from top to bottom obliquely installed to prefabricated cabin outside.
The lateral flap is connected by screw on the downside of the top frame.
The air-vent is the spaced long air-vent of length direction along air permeable waterproof part, and the long air-vent is provided with
It is more than two rows.
The air permeable waterproof part is provided with the multistage extended along the corresponding edge of top cover, is set between adjacent two sections by bridging
Cover plate connection.
The present invention uses above-mentioned technical proposal, and the bottom of top cover is provided with the air permeable waterproof part of strip, the air permeable waterproof
Part has the vertical flanging being connected with the top plate and a lateral flap being connected with the nacelle, and the lateral flap is towards prefabricated
It is less than top on the inside of cabin and with the L-shaped setting of vertical flanging, height of the lateral flap provided with air-vent and lateral flap
The top surface of framework, so, vertical flanging can play a part of preventing sleet water from entering in prefabricated cabin, even if there is part sleet water
Lateral flap is flowed to along air permeable waterproof part, because the height of lateral flap is less than the top surface of top frame, therefore sleet water is not yet
It can enter in prefabricated cabin, and the air-vent in lateral flap can connect the inner space of top cover and external world's holding, i.e., can
Play permeation functions and can and play iris action, it is simple in construction so as to realize the purpose of air permeable waterproof, it is easy to accomplish.
