A volume-adjustable L-shaped corridor-type double-layer curtain wall wind tunnel test model device

Abstract

The invention relates to the field of wind resistance test of building envelope structure, in particular to a volume adjustable wind tunnel testing model device for an L-shaped gallery type double curtain wall. The volume adjustable wind tunnel testing model device for an L-shaped gallery type double curtain wall provided by the invention can realize the continuous and stepless adjustment of the spacing between the L-shaped inner and outer curtain wall, has the advantages of convenient adjustment, simple data reading and high air tightness, and lays the foundation for eliminating the scale effect of the model and realizing the accurate evaluation of the dynamic wind load inside the double curtain wall.

Description

technical field [0001] The invention relates to the field of wind resistance tests of building envelope structures, in particular to an L-shaped corridor type double-layer curtain wall wind tunnel test model device with adjustable volume. Background technique [0002] With the increasing requirements for energy saving and environmental protection in buildings, corridor-type double-glazed curtain walls are increasingly used as building envelopes because of their good lighting, ventilation, heat and sound insulation properties. According to the different plane forms, the common corridor-type double-layer curtain wall can be divided into one-shaped and L-shaped. Due to the presence of vents on the outer surface of the double-layer curtain wall, while the inner curtain wall is exposed to wind, the outer curtain wall will be subjected to the joint action of wind loads on the inner and outer surfaces, which makes the force situation of the double-layer curtain wall very complicate...

AI Technical Summary

Problems solved by technology

For a simple line-shaped double-layer curtain wall, it is easier to change the distance between the inner and outer curtain walls, but for the L-shaped double-layer curtain wall, it is more complicated.

In order to meet the simple and continuous adjustment of the distance between L-shaped double-layer curtain walls, it is necessary to design a special double-layer curtain wall test model device, but unfortunately there is no similar test device yet.
