Method and device for reducing wind pressure to building

Abstract

The invention discloses a method and a device for reducing a wind pressure to a building, which solve problems about the method and interface for accessing conventional structural calculation and analysis software and problems about the method and the device for handling noises, rainy weather and condensed water during the reduction of the action applied by the wind pressure onto the building. Passages are arranged between the windward side and leeward side of the building so as to make wind run through a building body; positions, number and cross-sectional sizes of the passages on the surfaces of the building are determined to acquire input parameter values required by the conventional structural calculation software; and the conventional structural calculation software is utilized to finish the structural calculation, force analysis and the design of a structure and components of the building. Therefore, the method and the device for reducing the wind pressure can be actually applied to engineering, engineering cost is reduced and structural security is improved; mufflers and rainwater and condensed water drainage systems are arranged in the wind passages; and the method and thedevice are mainly applied to super high-rise buildings and high-rise buildings of shallow rectangular shapes, particularly regions with strong wind and low earthquake intensity.

Problems solved by technology

[0004] In order to solve the existing technology, there is no solution to the problem of the method and interface that need to be connected with the current structural calculation and analysis software, as well as the noise problem that the device generates under most weather conditions, and the water accumulation in the device is removed under heavy rain and wind conditions. The problem of condensed water appearing in the device under humid conditions, the present invention provides a method for reducing wind pressure of buildings and its device, starting from reducing the effect of wind load on buildings, solving practical problems in engineering applications, reducing project cost, increasing safety of building structures

[0006] In order to solve the noise problem generated by the existing wind pressure reduction method under most weather conditions and the water accumulation in the device under heavy rain and wind conditions and the problem of condensed water in the device under wet conditions, the wind pressure reduction method of the present invention The method adopts the following technical scheme: one of three kinds of resistive mufflers, resistive mufflers, and impedance composite mufflers is set in the air channel, or a combination of two of the three kinds of mufflers, or one of the three methods with all three kinds of mufflers; Set a slope of 0.5 to 5% in the muffler, and set up a rainwater and condensate drainage system at the lowest point of the slope; adopt one of the two methods of heat preservation or no heat preservation on the surface of the air channel pipe and the muffler; A total of 1 to 8 mufflers are set on the channel pipe, and the shells of these mufflers can be manufactured by one of two methods: integral or split; at the position where the air duct pipe is connected to the muffler, it can be sealed or not. Seal the connection one of two ways
