Description

Ecological cooperative structure of high-rise building outer wall

Technical Field

The utility model relates to a building design technical field specifically is an ecological cooperative construction of high-rise building outer wall.

Background

With the rapid development of economic society, various high-rise office buildings and residential buildings are more and more, and the application is more and more extensive. With the continuous development of the design concept of green and ecological buildings, the core design goals of high-rise buildings, such as green, environmental protection, energy conservation and health, are achieved, but the realization is difficult.

The phenomenon of vertical temperature difference of atmosphere is ubiquitous in nature. The temperature of the atmosphere generally decreases with the height from the ground, and the degree of temperature decrease for every 100m increase is called the vertical temperature decreasing rate. The average vertical temperature decrease rate monitored for air near the exterior wall of a high-rise building is about 1.65 ℃/100 m. In fact, the temperature gradient varies greatly, and sometimes the temperature may rise inversely with the increase in height from the ground, called temperature reversal or inverse temperature. The vertical temperature difference has great influence on convection in the atmosphere, when the high-altitude temperature is obviously lower than the ground temperature, the hot air on the ground rises rapidly, and the cold air on the upper layer falls to form convection; in addition, when the outer wall of the high-rise building is windward, the air pressure at the outer wall of the high-rise building is far higher than that at the outer wall of the low-rise building, and convection of air at the upper layer and the lower layer can be caused. However, most of the existing exterior wall facades of high-rise buildings are flat, and the convection flow is disordered, so that ecological regulation of high-rise and low-rise buildings cannot be realized.

The existing public fire fighting access external wall facade and the internal wall facade of a high-rise building are generally completely closed to the outside (the fire fighting door is used for isolating the public access such as a staircase and the wall body is used for isolating the external space and other internal spaces), and natural ventilation designs such as windows are not provided, so that smoke and the like entering the interior of the high-rise building can not be discharged when a fire disaster happens; fresh air can not be replaced for a long time, and the internal air is also dirty, which is not beneficial to human health.

Meanwhile, the high-rise building outer wall body adopting a solid structure is generally designed by mainly considering the design of adopting heat-insulating, heat-insulating and waterproof materials to realize the purpose of building energy conservation, but lacks the vertical ecological collaborative design of crossing floors in the height direction. The existing ventilation is carried out at a place provided with a door and a window, and other parts are all solid structures. Particularly, the outer walls corresponding to the staircases, public channels and the like are not provided with a natural ventilation and temperature regulation structure. In many buildings, although ventilation facilities such as glass windows are provided on the outer walls of public passages and the like, most buildings are closed all the year round due to various reasons such as dust prevention, rain prevention, insect prevention and the like, and thus the ventilation and air exchange effects cannot be achieved.

For a high-rise building with the height of more than 20 meters, the external wind pressure on the high-rise outer wall facade is far greater than that on the low-rise outer wall facade; the wind pressure of the windward side is far greater than that of the leeward side; the temperature of the outside air near the facade of the high-rise outer wall is higher than that of the outside air near the facade of the low-rise outer wall; moreover, this phenomenon is more pronounced as the total floor of the building increases.

Therefore, the external air convection of the external wall of the existing high-rise office building is not controlled, the function of cooperatively adjusting the longitudinal air and temperature of the internal and external parts of the building wall and the floors of the upper part and the lower part of the building is not realized, and the ecological cooperative design requirements of the environment protection, energy conservation, health and nature of the building cannot be met.
