Abstract
The invention discloses a roof board wind resistance standard testing device and a testing method. Through simulating the relationship between the deflection deformation of a metallic roof board and the wind load, the board thickness, the board profile and the purlin interval under the condition of a wind suction force, the testing method summarizes the test data of the wind suction resistance bearing capacity design of the die metallic roof board and supplies a domestic gap in the field. The invention solves the problem that currently the wind suction resistance bearing capacity design of the die metallic roof board lacks a reliable reference, thereby providing the standard reference for design staff to reasonably select the roof board profiles and optimize the design. The generalization and application of the roof board wind resistance standard testing device and the testing method have broad significance for the design and construction of the die metallic roof board under the action of the wind suction force.
Description
Technical field
The invention belongs to test method and test unit technical field, be specifically related to roof board wind resistance standard test method and test unit.
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 method with a kind of test, obtain the design and the reliable basis of constructing.This standard test method 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 method and application.
Summary of the invention
Problem to be solved by this invention provides roof board wind standard test method and experimental provision, described device comprises 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.
Described method comprises following steps: cause to upward pressure by inflation in closed container and simulate wind suction, cause the deflection deformation that the continuous increase of pressure makes progress the roof boarding generation in the closed container 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, sum up different templates, thickness of slab, purlin load-deflection relation apart from correspondence.
Beneficial effect of the present invention:
The invention solves 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 is a structural representation of the present invention.
