Description
Technical field
Wind detection device is resisted strenuously the present invention relates to a kind of metal Roof multiple pressure.
Background technology
With the development of science and technology, various modern buildings are presented in face of people, such as glass wall, gold
Belong to body packaging etc..There is building of many novel buildings using the Roof system, especially steel construction of metal structure again at present, its
Roof system naturally also uses the Roof system of metal structure.Composite metal Roof system all types of industries, physical culture, amusement,
Using more and more extensive in the buildings such as exhibition center, retail supermarket.
The wind loading rating of the building of metal structure especially metal Roof, directly influence the safety of building in itself and
Life-span, concerning life and production.At present, the means detected to metal Roof system are limited, and especially metal Roof is carried out
Resistive presses simulated test and detection, and the performance indications of whole roof boarding are mainly tested at the same pressure.And in fact, working as wind
It is larger in the stress of its edge, eaves or ridge when blowing to building surface, and blast suffered by other regions is much smaller than above-mentioned area
Domain, the height areal pressure gap of suffered blast is between 1~3 times, so existing wind resistance detection device can not be examined and determine effectively
The true wind resistance performance of metal Roof.
The content of the invention
The technical problems to be solved by the invention are to overcome the deficiencies in the prior art effectively to simulate metal house there is provided one kind
The metal Roof multiple pressure of the true wind loading rating in face resists wind detection device strenuously.
The technical solution adopted in the present invention is：The present invention includes passing through dividing plate in the casing of open topped, the casing
The air-pocket type pressure test chamber that closing is equipped with least two parts, each several part that the casing is separated is separated into, it is described
The top of casing places detection test specimen and the open-mouth of the casing is covered into closing, and the detection test specimen passes through locked instrument and institute
State casing to be mutually fixedly connected, each air-pocket type pressure test chamber is all connected with a blower fan, outside air is sent into every
Pressurizeed respectively in the individual air-pocket type pressure test chamber, until the detection test specimen is by the air-pocket type pressure test chamber
Body rises brokenly, so as to obtain the detection data of the detection test specimen different parts.
Air-valve adjusting part is equipped between each blower fan and the casing, with to each air-pocket type pressure test chamber
Internal pressure independent control, so as to apply different test pressures to the different parts of the detection test specimen.
The air-pocket type pressure test chamber forms air bag by covered rearing with plastic film.
The detection test specimen is metal roofing board.
The casing is adapted with the size of the detection test specimen.
The beneficial effects of the invention are as follows：Because the present invention is included in the casing of open topped, the casing by dividing plate point
It is divided into the air-pocket type pressure test chamber that closing is equipped with least two parts, each several part that the casing is separated, the case
The top of body, which places detection test specimen and covers the open-mouth of the casing, to be closed, the detection test specimen by locked instrument with it is described
Casing is mutually fixedly connected, and each air-pocket type pressure test chamber is all connected with a blower fan, outside air is sent into each
Pressurizeed respectively in the air-pocket type pressure test chamber, until the detection test specimen is by the air-pocket type pressure test chamber
Rise brokenly, so as to obtain the detection data of the detection test specimen different parts；Instant invention overcomes the defect of prior art, pass through quilt
Air-pocket type pressure test chamber at least two air bags of formation of at least two closings separated, it is each independent by least two blower fans
Driving, produces different pressure values respectively, and acts on same part test specimen, can effectively simulate the real wind-engaging of metal Roof
Pressure situation, therefore the present invention can effectively examine and determine the true wind resistance performance of metal Roof, be that a kind of metal Roof multiple pressure resists wind detection strenuously
Equipment.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of the embodiment of the present invention.
Embodiment
As shown in figure 1, the metal Roof multiple pressure of the present embodiment, which resists wind detection device strenuously, includes the casing 1 of open topped, institute
State in casing 1 and two parts are separated into by dividing plate 2, it is to avoid influence each other, envelope is equipped with each several part that the casing 1 is separated
Place detection test specimen 8 and cover the open-mouth of the casing 1 in the air-pocket type pressure test chamber 51,52 closed, the top of the casing 1
Lid closing, the detection test specimen 8 is mutually fixedly connected by locked instrument (not shown) with the casing 1, the gasbag-type
Test chamber 51,52 pressurize by covered rearing with plastic film formation air bag, therefore this detection device is referred to as " gasbag-type ", its cost compared with
Low, detection safety, good test effect, the casing 1 is adapted with the size of the detection test specimen 8, and the detection test specimen 8 is gold
The detection device of category roof boarding, i.e. the present embodiment is mainly used in the wind resistance detection of metal roofing board, each gasbag-type
Pressurization test chamber 51,52 is all connected with a blower fan 31,32, and outside air is sent into each air-pocket type pressure test chamber
Pressurizeed respectively in body 51,52, until the detection test specimen 8 is risen brokenly by the air-pocket type pressure test chamber 51,52, close
Under the good air bag effect of envelope property, metal roofing board is finally risen brokenly by air film, so as to obtain the detection different parts of test specimen 8
Data are detected, air-valve adjusting part 41,42 are equipped between each blower fan 31,32 and the casing 1, with to each air bag
Pressure independent control in formula pressurization test chamber 51,52, so as to apply different surveys to the different parts of the detection test specimen 8
Pressure testing power.
Above example is used by way of example only, is not construed as limiting the scope of the present invention, and implements form
It is not limited to described in above-mentioned embodiment.For example, three or three can be divided into the casing 1 according to test requirements document
Individual above section, and increase air bag number according to actual needs, the pressure value that test specimen applies three or more than three is tried
Test；So as to meet the test specimen in same scope, by the test requirements document of several different loads pressure.The size and volume of each air bag
It can be changed according to actual conditions, the pressure value of each air bag can according to actual needs be adjusted by air-valve adjusting part.
Instant invention overcomes the defect of prior art, by the air-pocket type pressure test chamber of at least two closings separated
Body at least two air bags of formation, are each operated alone by least two blower fans, different pressure values are produced respectively, and act on
On same part test specimen, metal Roof can be effectively simulated really by blast situation, therefore the present invention can effectively examine and determine metal Roof
True wind resistance performance, be that a kind of metal Roof multiple pressure resists wind detection device strenuously.
It the composite can be widely applied to wind resistance detection field.
