Problems solved by technology

[0003] (1) It is difficult to install pipes outside the exterior wall, and it is necessary to install and fix the prefabricated cement mortar thin-wall pipes to the exterior wall through installation equipment, which is dangerous for construction;
[0004] (2) During installation, it is difficult to align the air inlet reserved on the outer wall with the air inlet opened on the thin-walled cement mortar pipe, which affects the exhaust effect

Embodiment 1

[0018] Figures 1 and 2 show a common exhaust duct provided by Embodiment 1 of the present invention, which includes an outer wall 11, on which a number of air inlets 12 are opened in advance, and the outer side of the outer wall 11 is fixed. A number of ring beams 13 are provided, through which the ring beams 13 are used to lay bricks or cement prefabricated panels and enclose the part of the outer wall 11 including the air inlets 12 to form an exhaust pipe 14, and each of the air inlets 12 is connected with the device. A guide pipe 15 in the exhaust pipe 14 communicates, and the outlet 151 of the guide pipe 15 is set upward.

[0019] Specifically, the guide pipe 15 is a plastic elbow, and the guide pipe 15 is fixedly connected to the outer wall 11 through the mortar material 16; in addition, the inner and outer edges of the ring beam 13 are flush with the exhaust pipe 14 body, and the ring beam 13 is made of reinforced concrete.

[0020] More specifically, the cross-section ...

Embodiment 2

[0023] Fig. 3 and Fig. 4 show a kind of shared exhaust pipe provided by embodiment two of the present invention, and it is roughly the same as embodiment one, and its difference is: described guide pipe 15 is made of cement sand slurry material, makes guiding The service life of the pipe 15 is longer and the cost is lower, and the guide pipe 15 adopts a square structure and is fixed on the outer wall 11 by screws 152; the outer edge of the ring beam 13 is flush with the exhaust pipe 14, and the inner Edge protruding masonry.

[0024] The second embodiment provides a common exhaust pipe, the smoke enters from the air inlet 12 , and is exhausted upward through the outlet 151 of the guide pipe 15 , so that the smoke is smoothly discharged through the exhaust pipe 14 .

Embodiment 3

[0026] Fig. 5 and Fig. 6 show a kind of common exhaust duct provided by the third embodiment of the present invention, which is roughly the same as the first embodiment, the difference is that: the air inlets 12 are located in the exhaust A fire damper 17 in the pipeline 14 is connected, and the outlet 171 of the fire damper 17 is set vertically upwards. The fire damper 17 is a common device in the prior art, preferably the applicant's patent 200620015363.3 - special fire protection for kitchen and bathroom exhaust ducts Valve structure, the fire damper 17 is fixed on the outer wall 11 by screws 172 . In addition, the outer edge of the ring beam 13 and the exhaust pipe 14 protrude from the masonry, and the inner edge is flush with the masonry.

[0027] In the shared exhaust pipe provided by the third embodiment, the smoke enters from the air inlet 12 and is exhausted upward through the outlet 171 of the fire damper 17, so that the smoke is smoothly discharged through the exhau...

Abstract

A common exhaust duct comprise an outer wall, a plurality of air inlets on the outer wall, a device with diversion or transformation or fire-prevention function on the inner side of the air inlets, a plurality of ring beams fixed on the outer side of the outer wall, the common exhaust duct being composed of ring beam brick or cement pre-coated plate. Compared with the prior technique, the cement mortar thin-wall conduit special for the original outer wall is canceled and the gas is charged inside through the air inlet and discharged outside through the exhaust duct formed by the brick or cement pre-coated plate, therefore the efficacy of the original cement mortar thin wall conduit is satisfied with features of easy construction and low cost.

Description

technical field [0001] The invention relates to a shared exhaust pipe, which is especially suitable for setting a shared vertical exhaust pipe outside the walls of high-rise and super high-rise residential buildings. Background technique [0002] At present, kitchens and bathrooms in residential buildings share exhaust pipes, which are generally prefabricated with thin-walled pipes with cement mortar materials, and then vertically assembled into thin-walled pipes to form shared exhaust pipes. In order to avoid occupying the kitchen area by shared exhaust pipes, architectural designers Nowadays, common exhaust pipes are often installed outside the exterior walls, especially in high-rise and super high-rise residential buildings. Because the cross-section of the shared exhaust pipes is large and occupies the area of ​​the kitchen, more installation methods outside the exterior walls are used. However, this approach has the following problems in actual construction: [0003] (...
