Static sponge method wind load tester of exterior thermal insulation composite system

Abstract

The invention relates to a static sponge method wind load tester of an exterior thermal insulation composite system. The tester adopts a flexible stretching medium body combined by springs and foam silicone rubber sponge, thus the defect of the prior art that the strength of the adopted sponge material is insufficient can be overcome and the tester can test the wind loads of high-strength expanded polystyrene slab systems, high-strength extruded polystyrene slab systems, high-strength polyurethane systems and the like; the silicone rubber sponge material is different from the common polyurethane sponge material, the silicone rubber sponge material has higher strength; and tests prove that the tensile strength is up to more than 0.4MPa, thus the material can satisfy the strength requirement of the existing external thermal insulation system tensile test. Meanwhile, the test adopts the horizontal stretching mode and thin flexible medium material is required, or else the flexible medium material has the problem of falling, thus the combination mode of the springs and the silicone rubber sponge material is adopted, the thickness of the sponge material is reduced and the springs are used to ensure the flexibility. The tester of the invention adopts the horizontal stretching mode to replace the only vertical stretching mode, thus meeting the actual testing needs.

Description

technical field [0001] The invention relates to the field of wind load testing of an external wall thermal insulation system, in particular to a wind load tester for a static sponge method external thermal insulation system of an external wall. Background technique [0002] There are many factors that affect wind loads. Differences in various ground conditions in different regions, changes in the conditions of the structure itself, and differences in shape and surface roughness in different areas of the same building will all lead to changes in the wind load on the structure. Under the action of wind load, the structure will produce a certain movement, which in turn will cause the change of wind pressure on the surface of the structure, coupled with the mutual influence between adjacent buildings, all make the determination of the wind load on the structure quite complex. [0003] According to the literature, there are mainly four methods for wind load analysis: [0004] 1...

AI Technical Summary

Problems solved by technology

This tester not only overcomes the shortcomings of the prior art that cannot be stretched horizontally for wind load testing, but also can test the wind load of high-strength expanded polystyrene board systems, extruded polystyrene board systems, polyurethane systems, etc.
