Description

A remote-controlled vent for tensioned membrane buildings

technical field

The invention relates to a natural ventilation opening for improving the indoor environment comfort of a tension membrane building by using air convection. .

Background technique

Tensile membrane structure buildings originated from tents built with ropes, animal skins, and branches in ancient times, which can be called the oldest architectural form of human beings. However, after human settlements, such buildings have gradually been marginalized due to poor indoor environmental conditions, and have become temporary residences for special groups such as nomads, field workers, and the military. After the 1970s, architectural membrane materials with high tear strength, waterproof, high light transmittance and smooth surface, easy to clean, and anti-aging came out, coupled with the maturity of engineering computing science, which provided technology for a large number of applications of tensioned membrane buildings. condition. The original tensioned membrane buildings were mostly used for landscape sketches or open space shelters. For example, most of the 2002 World Cup venues held in Japan and South Korea used tensioned membrane roofs, such as the Seoul World Cup Stadium and Daegu Comprehensive Stadium. Later, tensioned membranes gradually began to be used on the roof of closed spaces, such as the "Sky Dome" gymnasium in Akita Prefecture, Japan. The roof is an orthogonal lattice space arch, and the membrane material is a single-layer glass fiber fabric. Up to 10%, creating a comfortable and bright interior space in severe cold regions. In addition, membrane materials have begun to be used as exterior walls and curtain walls of high-rise buildings. Located in Dubai, UAE, the nearly 100-meter-high Arabian Tower Hotel (Arabian Tower Hotel) uses double-layer membrane surfaces instead of glass curtain walls on its facade.

Over the past ten years, China's cable-membrane structure has made great progress in large-scale engineering projects. In 1997, the canopy of the 80,000-person stadium in Shanghai used a large-span space structure composed of radial cantilevered steel trusses covered with an umbrella-shaped membrane structure; the Shanghai Hongkou Stadium, which is specially used for football matches, also used saddle-shaped large-span cantilevered space cable trusses Supported membrane structure; In addition, there are Qingdao Yizhong Stadium, Zhejiang Yiwu Stadium, etc. The cable-membrane structure of Sunshine Valley at the 2010 Shanghai World Expo is currently the largest cable-membrane structure in the world.

The tensioned membrane structure uses membrane material as the roof or wall, but the membrane material is light and thin, its thermal buffering effect is weak, and its heat storage capacity is poor, resulting in an extremely unstable indoor thermal environment in the space covered by the membrane. The biggest disadvantage of conventional construction also hinders its widespread use. As the application range of tensile membrane buildings expands from large-span and large-space building types to ordinary public buildings, environmental problems such as uneven indoor temperature and humidity distribution and poor ventilation become more prominent in small building spaces. Because the membrane material is soft, ordinary windows cannot be installed, and ventilation is difficult. In the hot summer, the membrane roof itself is irradiated by the sun, and the temperature rises rapidly. In the room, the hot air rises and gathers at the lower part of the roof and cannot be discharged, making the indoor environment stuffy. The air is turbid and uncomfortable to live in.

At present, most tensioned membrane buildings are polymer membranes with integrated roof and wall. The ventilation method in tensioned membrane buildings is basically to set a hole with a rainproof roof at the highest point of the roof. However, due to the high building height of this type of opening, the ventilation openings set on it are high from the ground, beyond the range of manual operation, and can only be kept open all the time, and cannot be opened and closed freely, which is not conducive to adjustment according to the needs of the internal environment. For the wall surface made of tensile film, because the film material itself is soft, it is impossible to set ventilation openings according to the ordinary window opening method, and it is difficult to achieve natural indoor ventilation.

Contents of the invention

Aiming at the characteristic that the roof (wall) of a tensioned membrane building needs to be stretched and stressed when it is formed, the purpose of the present invention is to provide a remote control opening and closing ventilator assembled on site.

The basic idea of the present invention is: in the stretching stage of the stretching film construction, the steel frame of the vent is made to be balanced and fixed by using the tension force of the film itself, and the steel frame is equipped with a remote control receiver and a motor shaft box. Its rotation drives the louvers to open to form an airflow outlet to realize natural ventilation. When ventilation is not needed, the louvers can be closed by remote control.

The technical solution adopted in the present invention is: a remote-controlled air vent for tensioned membrane buildings, which has an external steel frame and an internal steel frame as the structural skeleton, and elastic steel pull rings are installed equidistantly on both sides of the internal steel frame to fix the horizontal venetian blinds Strips, the middle part of the horizontal venetian strips and the vertical strips are sewn and fixed, the upper part of the internal steel frame is equipped with a remote control receiver, and the lower part is installed with a motor shaft box, and the motor rotates under the remote control to tighten the vertical strips and drive the horizontal venetian strips On or off.

The present invention has the advantages that: the membrane material of the stretched membrane building needs to be stretched on site to be assembled and fixed on site, and it can be installed at any position on the roof or wall that needs ventilation, and the operation is simple and convenient. It can be opened and closed by remote control according to the user's requirements, and the heat pressure is used to form natural ventilation to achieve flexible control of indoor natural ventilation. It is opened when the hot summer or the greenhouse effect causes the interior to feel stuffy, and it is closed in winter or at night.

The air vent has simple construction technology and flexible control, and is suitable for buildings with tensioned membranes as roof and wall materials.
