Problems solved by technology

However, in contrast, the application design and construction acceptance standards of profiled metal roof panels are relatively backward, especially the problem of wind resistance and suction that has the greatest impact on profiled metal roof panels has not been well resolved. In some areas, the light roof panels of many workshops are partly or completely lifted due to unreasonable design or construction problems, causing major economic and safety problems
The main reason is that neither designers nor construction personnel fully consider the influence of wind suction, and the deeper reason is that there is no reliable design and construction basis.
Because it is too difficult to use analysis software to simulate the influence of wind suction on roof slabs, and no satisfactory theoretical calculation method can be obtained at present, so it is imperative to use an experimental method to achieve this effect and obtain a reliable basis for design and construction.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Fig. 1 is a schematic structural view of the present invention, comprising an airtight container 4 of upper purlin 1, profiled steel plate 2, length × width × depth = 6000 × 3000 × 100, plastic film, said upper purlin 1 and profiled steel plate 2 according to the project The conventional method is fixed on the surrounding frame 3, the bottom steel plate of the airtight container 4 is sealed with the surrounding steel plates, and the surrounding of the airtight container 4 is a groove 5 with a groove structure, and a sealing material 6 is housed in the groove 5. The sealing material 6 is squeezed tightly with the plastic film, and a displacement gauge 7 is installed on the top of the profiled steel plate 2, and when the atmospheric pressure is gradually increased, the readings on the displacement gauge 7 are recorded.

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 [0001] The invention belongs to the technical field of test methods and test devices, and in particular relates to a standard test method and test device for wind resistance of roof panels. Background technique [0002] In recent years, with the rapid development of the national economy, the application of profiled metal roof panels in the roofing system of industrial plants has become more and more extensive, and the output has also shown an increasing trend year by year. It can be said that the application of profiled metal roof panels has entered a period of rapid development . However, in contrast, the application design and construction acceptance standards of profiled metal roof panels are relatively backward, especially the problem of wind resistance and suction that has the greatest impact on profiled metal roof panels has not been well resolved. Due to unreasonable design or construction problems, the light-weight roof panels of many factories have ...
