Curtain wall dynamic wind pressure detection method

Abstract

The invention discloses a curtain wall dynamic wind pressure detection method. The method comprises the following steps: S1, mounting a curtain wall; s2, installing detection equipment; s3, assembling: specifically, the fixing frame provided with the curtain wall is placed below detection equipment; one end of the fixing frame is limited through the detection equipment, and then the other end of the fixing frame is connected through the detection equipment; s4, hoisting: gradually lifting one end of the fixing frame upwards, and controlling the upper end of the detection equipment to move along the horizontal direction at the same time until the fixing frame is hoisted to a vertical state; s5, spraying: uniformly and continuously spraying water on the surface of the curtain wall through a spraying mechanism arranged on the detection equipment; s6, applying dynamic wind pressure: the dynamic wind pressure is applied to the surface of the curtain wall through a propeller fan, and thus the dynamic pressure watertight performance of the curtain wall is detected. The detection period is shortened, and the whole detection process is more convenient and faster; and the test result can be more accurate.

Description

technical field [0001] The invention relates to the field of curtain wall performance detection, in particular to a curtain wall dynamic wind pressure detection method. Background technique [0002] In coastal areas, in addition to the four-character test of conventional building curtain walls, it is also necessary to conduct performance tests on building curtain walls under typhoon and rainstorm conditions; therefore, a dynamic wind pressure system is developed in the laboratory to simulate the typhoon and rainstorm environment in the natural state. It is very important to study the pressure bearing performance of building curtain wall under dynamic wind pressure. The national standard GB / T29907-2013 is about the dynamic pressure and watertight performance test of the curtain wall. In order to spray water evenly and continuously on the outer surface of the test piece according to the specified amount of water, after forming a continuous water film on the surface of the test...

AI Technical Summary

Problems solved by technology

[0004] Due to the relatively large area of ​​the curtain wall to be tested, when testing the dynamic pressure and watertight performance of the curtain wall outdoors, the boom of the crane will not be limited by the height, and the boom of the crane can smoothly hoist the fixed frame to the vertical When it is necessary to test the dynamic pressure and watertight performance of the curtain wall indoors, due to the limitation of the height of the indoor site, it will be difficult for the boom of the crane to hoist the fixed frame smoothly, which will cause problems for the indoor The detection work brings limitations
