Embodiment Construction
[0021] The present invention is described in further detail with reference to the accompanying drawings and specific embodiments.
[0022] Such as Figure 1~5 As shown, a volume-adjustable corridor-type double-layer curtain wall wind tunnel test model device includes: the middle part of the test model device is provided with an upper and lower two-layer corridor-type double-layer curtain wall. The corridor-type double-layer curtain wall is composed of an outer curtain wall 3 and an inner curtain wall 4 . The outer surface of the outer curtain wall 3 is provided with an air inlet 1 and an air outlet 2 up and down. The inner curtain wall 4 is made of thick plexiglass panels and can slide along the length of the building. The inner curtain wall 4 is connected to a tie rod 6 through a ball joint, the tie rod 6 is connected to the tie rod 7 through a ball joint node, and the tie rod 7 is rigidly connected to a solid shaft 8, which is installed at the center of the model and runs ...

The invention provides a gallery-type double-layer curtain wall wind tunnel test model device with an adjustable volume. Two gallery-type double-layer curtain walls are disposed on the center of the device, and each comprises an outer curtain wall, an inner layer, and a gallery between the outer curtain wall and the inner curtain wall. A separating floor for separation is arranged between the two adjacent gallery-type double-layer curtain walls. The two gallery-type double-layer curtain walls are arranged on a foundation floor. The inner side of the inner curtain wall is connected with a movement mechanism. The movement mechanism moves the inner curtain wall horizontally on the foundation floor and the separating floor to form a space change of the gallery between the inner curtain wall and the outer curtain wall. A pressure measuring tube passes through the inner curtain wall to measure the wind pressure inside the gallery. The other end of the pressure measuring tube is connected with a pressure scanning valve. The invention provides a favorable experimental device for studying a method for correcting the scale effect of a double-layer curtain wall model, and also lays a foundation for accurately testing the wind pressure pulsation between the double curtain wall galleries.
Description
technical field [0001] The invention relates to the field of wind-resistant design and test of building peripheral protective curtain wall structure, in particular to a volume-adjustable corridor-type double-layer curtain wall wind tunnel test model device. 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. The corridor type double-layer curtain wall is composed of the inner curtain wall, the outer curtain wall and the corridor cavity between the inner and outer curtain walls. Due to the presence of vents on the surface of the outer curtain wall of the double-layer curtain wall, while the inner curtain wall is exposed to the wind, the outer curtain wall will be subjected to the joint action of the wind load on the inner and outer surface...
