Problems solved by technology

However, the wind speed is not a design value that can be increased infinitely. Generally, the wind speed is 2-4.5m / s. The greater the wind speed, the greater the noise, and the loud noise on the roof will reduce the quality of the roof space.

Abstract

The invention relates to the field of constructional engineering, in particular to an efficient silent air duct well structure for a roof. According to the technical scheme, an expansion ventilation cavity is formed in the periphery of a prefabricated heating and ventilation air duct well; perforated ventilation aluminum plates are arranged on the four peripheral walls and the top of the expansion ventilation cavity; an aluminum plate top cover is arranged over the prefabricated heating and ventilation air duct well, and the elevation of the aluminum plate top cover is the same as that of the perforated ventilation aluminum plates; a rain shelter concrete overturned opening is arranged abutting against the part, with the prefabricated heating and ventilation air duct well, of the roof; an outward roof drainage slope within the range of the expansion ventilation cavity; a drainage floor drain is arranged at the indoor bottom of the part, with the prefabricated heating and ventilation air duct well, of a building. According to the efficient silent air duct well structure for the roof, the actual air inlet quantity and air exhaust quantity of the roof air duct well are effectively increased, noise is reduced, and the usage quality of the space of the roof is improved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to the structure of a roof heating and ventilation pipe well. Background technique [0002] The value of roof space is being fully explored and utilized more and more. To improve the ventilation performance and acoustic effect of roof duct wells in actual engineering use, and to optimize the original unsatisfactory form, some measures need to be taken to solve the problem of ventilation volume, rain resistance rate, The four-in-one requirement of noise reduction and aesthetics is to support and improve the environmental quality of the roof space and the comfort of people performing activities on the roof space. [0003] The louver design of the roof duct well generally adopts the form of rain-proof louvers, and the general design experience value of the effective ventilation area of ​​the rain-proof louvers is 0.3-0.5 (the effective ventilation area of ​​the perforated alumin...
