Description

Technical Field

[0001] The invention relates to the technical field of building design, in particular to a device suitable for reducing the floor height of a double-layer underground parking garage. Background Art

[0002] Underground garages are an effective way to utilize underground space for parking, and are sometimes built on the second floor or above. Underground garages include parking spaces, driveways, equipment rooms, and equipment pipelines. Equipment pipelines are generally suspended under beams, and smoke exhaust pipelines are laid along the designed path, with smoke exhaust ports covering the entire smoke-proof partition.

[0003] The current regulations require that the net height of the underground garage driveway should not be less than 2.2m. Each floor should also consider 0.4m for smoke exhaust pipelines, 0.3m for fire sprinkler pipelines, 0.2m for cable trays, and 0.7m for structural beams. After the comprehensive arrangement of pipelines, the single-layer height is generally above 3.7m to meet the minimum net height. The ground is generally considered to have at least 0.5m of cover to meet the greening index. The minimum depth of a double-layer underground garage is generally above 8m. The existence of equipment pipelines is the reason for the increase in floor height. The deeper the underground garage is buried, the more difficult the construction will be, and the construction cost will increase accordingly. Summary of the invention

[0004] The object of the present invention is to provide a device suitable for reducing the floor height of a double-layer underground parking garage to solve the problems raised in the above-mentioned background technology.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, the present invention provides a technical solution: a device suitable for reducing the floor height of a double-layer underground parking garage, comprising: a smoke exhaust machine room 4 arranged in the underground first floor garage and a smoke exhaust pipe 3 arranged in the underground first floor garage, the number of smoke exhaust pipes 3 is at least two, one smoke exhaust pipe 3 is used to serve the underground first floor garage, and the other smoke exhaust pipe 3 is used to serve the underground second floor garage, a smoke exhaust port 6 is opened on the smoke exhaust pipe 3, the smoke exhaust port 6 is used to introduce the smoke in the garage into the smoke exhaust pipe 3, part of the smoke exhaust port 6 is connected to the smoke exhaust machine room 4, mainly used to connect the smoke exhaust machine room 4 and the smoke exhaust pipe 3, so as to achieve the effect of controlling exhaust, the garage is provided with a reserved hole for the smoke exhaust port 6, when the smoke exhaust pipe 3 is constructed and installed, it is more convenient to install the smoke exhaust port 6, and it is also convenient to position the smoke exhaust port 6, so as to ensure that the position where the smoke exhaust port 6 is set can exhaust all the smoke in the garage.

[0023] like Figure 2 As shown, both the underground garage on the first floor and the underground garage on the second floor are provided with a smoke exhaust port 6 to ensure that the smoke in the underground first and second garages can be completely exhausted without omission. The smoke exhaust pipe 3 stacked on the bottom floor passes through the underground garage on the first floor to connect to the roof of the underground garage on the second floor to open a smoke exhaust port 6. Since the smoke exhaust pipe 3 serving the underground first and second garages is stacked and arranged on the ground of the first garage, it is necessary to extend from the ground of the underground first garage to the top floor of the second garage through a branch pipe, and a smoke exhaust port 6 is opened. The branch pipe passing through the reserved hole on the ground of the underground garage is a branch of the smoke exhaust pipe 3, which is used to connect the smoke exhaust pipe 3 on the underground garage floor and the smoke exhaust port 6 on the top floor of the second garage to ensure a sealed connection. The smoke exhaust pipe 3 and the branch pipe stacked on the bottom floor for exhausting smoke from the underground second garage are closed with blocks and cover plates to prevent the smoke from the underground second garage from leaking into the underground first garage. The closed structure meets the fire resistance limit requirement of 2.0 hours. The smoke exhaust pipe 3 and the smoke exhaust machine room 4 do not hinder the parking space 1 and the driveway 2, ensuring smooth driving of vehicles in the garage.

[0024] The smoke exhaust room 4 includes an air collecting chamber 41 and a smoke exhaust shaft 42 located in the underground garage. The air collecting chamber 41 is connected to the smoke exhaust pipe 3 to optimize the use function and conversion measures of the vent. The garage is also provided with equipment pipelines 5, which include smoke exhaust pipes 3, fire sprinkler pipelines and cable trays. The fire sprinkler pipelines and cable trays are laid under the beams and slabs, and the smoke exhaust pipes 3 are stacked on the ground of the underground garage, and the equipment pipelines 5 are arranged on the smoke exhaust pipes 3.

[0025] As shown above, this embodiment is a device suitable for reducing the floor height of a double-story underground parking garage, including: a smoke exhaust machine room 4 arranged in the underground first floor garage and a smoke exhaust pipe 3 arranged in the underground first floor garage, a smoke exhaust port 6 is opened on the smoke exhaust pipe 3, the smoke exhaust pipe 3 is connected to the smoke exhaust machine room 4, a reserved hole for the smoke exhaust port 6 is opened on the garage floor, the underground first floor garage and the underground second floor garage are both provided with a smoke exhaust port 6, part of the smoke exhaust pipe 3 passes through the underground first floor garage and is connected to the smoke exhaust port 6 on the top plate of the underground second floor garage, the smoke exhaust pipe 3 passing through the underground first floor garage is a branch pipe of the smoke exhaust pipe 3, and the branch is connected to the smoke exhaust pipe 3 on the underground first floor garage, the smoke exhaust pipe 3 and the smoke exhaust machine room 4 do not hinder the parking space 1 and the driveway 2, the smoke exhaust machine room 4 includes an air collecting chamber 41 and a smoke exhaust shaft 42 arranged in the underground first floor garage, and the garage is also provided with an equipment pipeline 5, which is arranged on the top of the garage.

[0026] The device is suitable for reducing the height of a double-layer underground parking garage. The exhaust pipe 3 is stacked on the ground of the underground garage. The exhaust pipe 3 at the top serves the underground garage. A smoke outlet 6 is opened on the top of the exhaust pipe to exhaust smoke in the first garage. The second underground garage is connected to the second underground garage by the exhaust pipe 3 stacked at the bottom, passing through the underground garage, and opening the exhaust outlet 6 on the top plate. The exhaust pipe 3 passing through the ground of the underground garage is a branch pipe of the exhaust pipe 3, which is used to connect the exhaust pipe 3 of the underground garage layer and the exhaust outlet 6 on the top of the second garage to ensure a sealed connection. The exhaust pipe 3 serving the second underground garage is closed with blocks and cover plates together with the branch pipe to prevent the smoke of the underground second garage from leaking into the underground first garage. The closed structure meets the fire resistance limit requirement of 2.0 hours. The exhaust pipe 3 and the exhaust machine room 4 do not hinder the parking space 1 and the driving lane 2, ensuring smooth driving of vehicles in the garage.

[0027] Since the two smoke exhaust pipes 3 are stacked on the ground of the underground garage and do not occupy the space on the top of the garage, the space for installing the smoke exhaust pipes 3 is reduced. Although a small number of parking spaces are reduced, the floor height of a single-layer garage can be effectively reduced by 0.4 meters and the floor height of a double-layer garage can be reduced by 0.8 meters. It also reduces one line that intersects with other equipment pipelines 5 in the garage, which is beneficial to the optimized layout of other pipelines.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
