Description

Technical Field

[0001] The utility model relates to the technical field of building design, in particular to a residential basement ventilation system. Background Art

[0002] There are more and more underground projects in newly built residential projects. Considering the convenience of residents' later use, the basement will be given to residents as a storage room. In order to meet the residents' needs for comfortable use, the clear height of the basement corridor has been increased from the original 2.0 meters to 2.3 meters. Therefore, strict requirements are put forward for the clear height of the basement storage room and the clear height of the corridor.

[0003] At present, for residential underground construction projects, ventilation and fire ventilation systems must be set up according to the requirements of the specifications, and the requirements of the owners for indoor comfort must be met. Such underground projects often use mechanical ventilation (including: fans, air ducts, air valves and air outlets, and the indoor air and smoke are sent to the outside by the fans through the air outlet ducts). In order to achieve the effect of mechanical ventilation, the current conventional practice is to lay the air ducts of the mechanical ventilation system horizontally along the corridor of the basement or the bottom of the beam of the storage room, and the fan is hoisted or installed on the ground in the fan room. The air outlet of the air duct adopts downward air supply. Combined with the basement floor height setting, the air duct height generally needs to occupy a minimum of 300mm of the floor height, so that the clear height of the corridor will be reduced by at least 300mm, and the basement corridor will have strong and weak electricity bridges and heating, water supply and drainage pipes passing through. In order to meet the requirements of the basement clear height, it is often solved by increasing the floor height of the basement, which cannot meet the economic requirements of the project and affects the clear height of the corridor. Utility Model Content

[0004] The utility model aims to provide a residential basement ventilation system.

[0005] The utility model is implemented by the following technical scheme: a residential basement ventilation system, which includes a basement, a trench, a horizontal air duct, a fan, a vertical air duct, an exhaust shaft, a smoke exhaust shaft, and a smoke exhaust port;

[0006] The basement is provided with a smoke exhaust shaft and an exhaust shaft directly connected to the outside;

[0007] A valve plate foundation is provided at the bottom end of the basement, the smoke exhaust shaft is placed at the top of the valve plate foundation, and the trench is opened inside the valve plate foundation;

[0008] The horizontal air duct is laid in the trench, and a plurality of vertical air ducts are connected to the horizontal air duct. The top of the vertical air duct passes through the valve plate foundation and extends into the smoke exhaust shaft. The vertical air duct is provided with a smoke exhaust port connected to the smoke exhaust shaft, and the bottom end of the smoke exhaust shaft is fixedly connected to the top end of the valve plate foundation.

[0009] One end of the horizontal air duct is connected to the inlet of the fan through a connecting pipe. The fan is placed in a fan room in the basement. The outlet of the fan is connected to the exhaust shaft directly leading to the outside.

[0010] Furthermore, the smoke exhaust port is provided with air outlet louvers.

[0011] Furthermore, a support plate flush with the valve plate foundation is laid on the top of the trench.

[0012] The utility model has the advantages that the combination of horizontal air duct, smoke exhaust shaft and vertical air duct is used, so the location of the smoke exhaust shaft is more flexible. The horizontal air duct adopts an underground design, which can reduce the problem of basement floor height and is more economical than the construction method of increasing the floor height. At the same time, it ensures the clear height requirement of the corridor and reduces the occupied area of ​​the basement.

[0013] Air and smoke are discharged out of the smoke exhaust shaft through the vertical air duct, horizontal air duct, fan, and exhaust shaft in turn. Under the action of the vertical air duct and air outlet louvers, debris falling into the smoke exhaust shaft is intercepted to prevent it from entering the vertical air duct.
