Description
Technical field
The utility model belongs to the test unit technical field, is specifically related to a kind of roof board wind resistance standard test device.
Background technology
In recent years, along with high speed development of national economy, the die mould metal roofing board in the application of industrial premises Roof system more and more widely, output also is ascendant trend year by year, we can say that the application of die mould metal roofing board has entered the period of high speed development.But what present a contrast with it is that the Application Design and the delivery receiving acceptance standard of die mould metal roofing board is backward relatively, particularly the wind resistance suction problem that the die mould metal roofing board is had the greatest impact is not well solved, in the bigger area of wind load, the light-weight roof slab of many factory buildings has caused bigger economy and safety problem because the unreasonable or construction problem of design causes by the part or all starts.Studying carefully its main cause and be designer no matter or workmen lacks fully the influence of wind suction and considers that deeper reason is not design and manufacture bases reliably.Because with analysis software simulation wind suction to roof boarding to influence difficulty too big, must not go out satisfied theoretical calculation method at present, reach this effect so the task of top priority is a device with a kind of test, obtain the design and the reliable basis of constructing.This resistance standard test device formally puts forward based on this, and design and the construction under the wind suction effect all has wide significance to the die mould metal roofing board for popularization of this test unit and application.
The content of utility model
Problem to be solved in the utility model provides a kind of roof board wind resistance standard test device, comprise top purlin, profiled sheet, on the framework around described top purlin and profiled sheet are fixed on, it is characterized in that: also comprise closed container, plastic sheeting, the bottom steel plate of described bottom closed container and steel plate sealing all around, around the described closed container is the groove of trench structure, encapsulant is housed in the groove, described encapsulant and described plastic sheeting jam-packed, displacement meter is installed on described profiled sheet top.
Draft tube, escape pipe and air pressure gage pipe are equipped with in described closed container bottom, the draft tube valve is housed on the described draft tube, the escape pipe valve is housed on the described escape pipe, and described air intake valve front end is installed a turbine pressure hair-dryer, and the air pressure gage pipe port is installed an air pressure gage.
The specification of described turbine pressure hair-dryer is 17m
3/ min, described draft tube and escape pipe choosing can be born the pipeline of the pressure of 30kpa.
Described plastic sheeting is a sealed polyethylene plastic.
Described closed container is for long: wide: dark=60: 30: 1 container.
The beneficial effects of the utility model:
The utility model has solved die mould metal roofing board wind resistance suction Design of Bearing Capacity does not have the problem of reliable basis, thereby provides the standard foundation for the designer reasonably selects roof boarding template and optimal design.
Description of drawings
Fig. 1-1 is a structural representation of the present utility model.
Fig. 1-2 increases the structural representation of air pressure gage pipe and air pressure gage for the utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1-1 is a structural representation of the present utility model, comprise top purlin 1, profiled sheet 2, long: wide: dark=60: 30: 1 closed container 4, plastic sheeting, on the framework 3 around described top purlin 1 and profiled sheet 2 are fixed on by conventional way in the engineering, the bottom steel plate of described closed container 4 and steel plate sealing all around, around the described closed container 4 is the groove 5 of trench structure, encapsulant 6 is housed in the groove 5, described encapsulant 6 and described plastic sheeting jam-packed, displacement meter 7 is installed on described profiled sheet 2 tops, when progressively increasing atmospheric pressure, the reading on the record displacement meter 7.
Fig. 1-2 increases the structural representation of air pressure gage pipe and air pressure gage for the utility model.Draft tube 8, escape pipe 9 and air pressure gage pipe 10 are equipped with in described closed container 4 bottoms, bottom inflow pipe 8, escape pipe 9 and air pressure gage pipe 10 must seal, on the described draft tube 8 draft tube valve 11 is housed, on the described escape pipe 9 escape pipe valve 12 is housed, draft tube valve 11 and the 12 control inlet and outlet of escape pipe valve, draft tube 8 and escape pipe 9 requirements can be born the pressure of 30kpa, and it is 17m that described draft tube valve 11 front ends are installed a specification
3Turbine pressure hair-dryer 13 air feed of/min, air pressure gage pipe 10 ports are installed an air pressure gage 14.
Described plastic sheeting is a sealed polyethylene plastic 15, simulate wind suction by in closed container 4, inflating to cause to upward pressure, cause the deflection deformation that the continuous increase of pressure makes progress the roof boarding generation in the described closed container 4 by continuous inflation, up to reaching the permission maximum immunity value.Read the pressure values of each deformation stage displacement correspondence by air pressure gage 14, sum up different templates, thickness of slab, purlin load-deflection relation apart from correspondence.Inner sealed polyethylene plastic 15 must be enough big, can be adjacent to superstructure fully, pressure can be passed to top profiled sheet 2 fully and be as the criterion, and displacement meter 7 is installed on profiled sheet 2 tops, when progressively increasing atmospheric pressure, and record displacement meter reading.
