Abstract

The utility model relates to an exhaust pipeline structure of a high-storey building, which is mainly composed of a branch pipeline [2], a first main pipeline [1] and a second main pipeline [3], wherein, the first main pipeline [1] and the second main pipeline [3] are abreast arranged at both sides of the branch pipeline [2]. Air inlets [5], [6], [8], [9] are respectively arranged on the outer walls of pipelines between the branch pipe [2] which is separated by blocking plate [12] and rooms of the building. Exhaust outlets [4], [7], [10], [11] are respectively arranged on partition boards between the branch pipeline [2] and the main pipeline. The structure decreases the resistance of exhaust pipeline to airflow, and thus, gas in house rooms in the building can be successfully exhausted. The utility model is mainly used for exhausting gas in rooms of high-storey buildings.

Description

Exhause pipe structure of high-storey building

The utility model relates to the air discharging structure that a kind of building indoor exhaust road, particularly high-rise building (buildings more than ten layers) use.

Exhaust duct in the existing high-rise building, how to constitute by two less steam vents that are set up in parallel, one of them steam vent is born the indoor gas discharging task of each floor of bottom, another steam vent is born the indoor gas discharging task of each floor of top, its shortcoming is, the exhaust load that two steam vents are born is bigger, and less steam vent has bigger resistance to air-flow, is difficult to discharge smoothly the indoor gas of building.

The purpose of this utility model is, will improve the air discharging structure of high-rise building exactly, reduces the resistance of exhaust duct to air-flow, makes the building indoor gas be able to smooth discharge.

In order to achieve the above object, the solution that the utility model is taked is: the utility model comprises trunk line, branch pipe(tube) and air inlet port, described trunk line is two, these two trunk lines, be arranged side by side both sides respectively at branch pipe(tube), constitute three pipelines, three row of conduits air passage structures side by side, on each section and the pipeline outer wall between the respective chambers of the above-mentioned branch pipe(tube) that constitutes every joint exhaust duct, an air inlet port is set respectively, on each section dividing plate between the trunk line of above-mentioned branch pipe(tube) and one side, order by each joint exhaust duct, the compartment of terrain is provided with exhaust opening, between the trunk line of described branch pipe(tube) and its opposite side on each section dividing plate, order by each joint exhaust duct also is provided with exhaust opening in the compartment of terrain, be adjacent respectively saving in the exhaust duct, main, the direction difference of exhaust opening is set on the dividing plate between the branch pipe(tube), each section branch pipe(tube) is connected with different trunk lines.In described branch pipe(tube), each saves the two ends that air inlet port and each section of respective vent ports are set on the exhaust duct, be respectively arranged with a closure plate, above-mentioned air inlet port and respective vent ports are enclosed in corresponding each section branch pipe(tube), perhaps in above-mentioned branch pipe(tube) each section corresponding to each joint exhaust duct, at an end of air inlet port that is provided with separately and respective vent ports (upper end or lower end one of them) closure plate is set respectively, described each closure plate is identical.

The flue gas of set each exhaust opening of the utility model is discharged on dividing plate (being the dividing plate between branch pipe(tube) and the trunk line) wall of a side, a dustpan-shaped exhaust guide pipe also can be set, so that emission gases is carried out water conservancy diversion respectively.

Because the utility model has been taked above-mentioned three structures that pipeline is arranged side by side, when making each floor indoor gas discharging, can obtain shunting, therefore can reduce the resistance of exhaust duct effectively to air-flow, make the indoor gas discharging of each floor of high-rise building comparatively smooth and easy, thereby improved smoke evacuation, the exhaust efficiency of exhaust duct.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the schematic diagram of embodiment 1 described the utility model agent structure;

Fig. 2 is an A-A sectional view of the present utility model shown in Figure 1;

Fig. 3 is a B-B sectional view of the present utility model shown in Figure 1;

Fig. 4 is embodiment 2 described the utility model structural representations.

Embodiment 1, in schematic diagram shown in Figure 1, the utility model comprises trunk line, branch pipe(tube) and the air inlet port that is arranged side by side, be characterized in, every joint exhaust duct is arranged side by side by branch pipe(tube) 2, first trunk line 1 and second trunk line 3 and forms, described first trunk line 1, second trunk line 3 are arranged side by side respectively in the both sides of branch pipe(tube) 2, and first trunk line 1 and second trunk line 3 are straight-through passage.Constitute on each section branch pipe(tube) 2 of every joint exhaust duct and the respective storey pipeline outer wall between indoor, be respectively arranged with first air inlet port 5, second air inlet port 6, the 3rd air inlet port 8 and the 4th air inlet port 9.On two sections dividing plates spaced apart from each other between the above-mentioned branch pipe(tube) 2 and first trunk line 1, be respectively arranged with second exhaust 11 and the 4th exhaust opening 10, on two sections dividing plates spaced apart from each other between the above-mentioned branch pipe(tube) 2 and second trunk line 3, be respectively arranged with first exhaust opening 4 and the 3rd exhaust opening 7.In branch pipe(tube) 2, each saves the two ends that air inlet port and each section of respective vent ports are set on the exhaust duct, be respectively arranged with a closure plate identical with closure plate 12, described air inlet port and corresponding exhaust opening are enclosed in corresponding each section branch pipe(tube) 2, and itself and other adjacent each section branch pipe(tube) 2 is separated, also can be in above-mentioned branch pipe(tube) 2 each section corresponding to each joint exhaust duct, at the air inlet port and both ends of respective vent ports (one of upper end or lower end) that are provided with separately a closure plate is set respectively, described closure plate is all identical, no longer provides respective drawings herein.Adopt said structure can reach the gas shunting, effectively reduce the purpose of gas-flow resistance.In A-A sectional view shown in Figure 2, first exhaust opening 4 is arranged on the dividing plate between the branch pipe(tube) 2 and second trunk line 3, and first air inlet port 5 is arranged on branch pipe(tube) 2 and the respective storey pipeline outer wall between indoor.In B-B sectional view shown in Figure 3, second air inlet port 6 is arranged on branch pipe(tube) 2 and the respective storey pipeline outer wall between indoor, and second exhaust opening 11 is arranged on the dividing plate between the branch pipe(tube) 2 and first trunk line 1.

Embodiment 2, and the utility model structure is except that other adds the exhaust guide pipe, and other structure is all identical with embodiment 1 described structure.In schematic diagram shown in Figure 4, above-mentioned first exhaust opening 4, second exhaust opening 11, the 3rd exhaust opening 7 and the 4th exhaust opening 10 flue gas (or gas) are separately discharged on the dividing plate (being the dividing plate between described branch pipe(tube) and the corresponding trunk line) of a side, a dustpan-shaped exhaust guide pipe is set respectively, described each dustpan-shaped exhaust guide pipe is all identical with dustpan-shaped exhaust guide pipe 13, the setting of above-mentioned dustpan-shaped exhaust guide pipe more helps the smooth discharging of each floor indoor gas.

Said structure is just represented a segment structure of described exhaust duct, can also it be made corresponding extension according to the quantity of floor, and the whole air discharging structure after the extension also belongs to protection domain of the present utility model.
