Description

Technical Field

[0001] The invention relates to the technical field of tension adjustment in air film building construction, in particular to a tension adjustment device in air film building construction. Background Art

[0002] Air-film buildings are a type of building that relies on the difference in internal and external air pressure to support the membrane structure. Its construction process has certain particularities. According to the design requirements, the various parts of the membrane are connected. The main connection methods include heat sealing and sewing. Heat sealing is to melt the edges of the membrane material and bond them together through high temperature. Sewing is to connect the membrane material with special sutures. The connection parts should be firm and sealed to ensure the air tightness of the air-film building. During the tension adjustment process, the membrane material should be prevented from being damaged due to excessive tension, and the speed and amplitude of the tension increase should be controlled to avoid sudden application of excessive tension. There are various types of tension adjustment devices for air-film building construction, among which the screw-nut tension adjustment device is one of them. The screw is driven to rotate by a motor, and the movable block on the screw moves horizontally. The movable block drives the movable plate to rotate around the hinge seat through the support rod, thereby adjusting the height of the connecting column and realizing the adjustment of the pulling height and tension of the air film.

[0003] During use, the screw-nut type tension adjustment device can only pull the air film to adjust the air film height. Since it is driven by a motor and cannot be controlled manually, when the air film tension is adjusted, the height cannot be adjusted according to the air film, and the tension of the air film cannot be detected and controlled, resulting in inconvenience in adjusting the tension.
