Abstract

The invention provides a three-dimensional smoke exhaust system of an underground garage, and relates to the technical field of underground garage smoke exhaust pipe arrangement. The three-dimensional smoke exhaust system comprises two floors of underground garages, and smoke exhaust through holes are formed in floor slabs of the basement of the two floors of underground garages in a locally hollow mode; the smoke exhaust through holes are used for communicating with spaces of the upper and lower floors of the underground garages, and mounting grooves are formed in the lower portions of top plates of the basement of the two floors of underground garages; the mounting grooves are located above the smoke exhaust through holes; and smoke exhaust assemblies are arranged in the mounting grooves. According to the three-dimensional smoke exhaust system, the maximum utilization of the spaces of the underground garages is realized, and the space utilization rate of the underground garages is improved.

Description

technical field [0001] The invention relates to the technical field of arrangement of smoke exhaust pipes in underground garages, in particular to a three-dimensional smoke exhaust system for underground garages. Background technique [0002] The garage is a building used to park and store cars. The underground garage refers to a garage whose indoor floor surface is lower than the outdoor floor surface and exceeds half the net height of the garage on this floor. [0003] According to the requirements of "Code for Fire Protection Design of Garages, Repair Garages, and Parking Lots" and "Technical Standards for Smoke Prevention and Smoke Exhaust Systems in Buildings", underground garages must be equipped with mechanical smoke exhaust systems. Due to the large volume of the smoke exhaust duct, the height of the main pipe can reach about 400mm. Considering the actual situation such as the installation space and the addition of lower nozzles for the sprinkler system, the smoke ex...
