Embodiment 1

[0044] figure 1 , Is a top view of the vertical shared exhaust duct provided by the first embodiment of the present invention. The vertical shared exhaust duct 10 is formed in the corresponding preset hole 21 on the floor of the inner corner 20 of the floor room. When viewed in cross section, the vertical shared exhaust duct is formed by butting two L-shaped thin-walled members, one of which is L-shaped The thin-walled member is provided with an air inlet (not shown in the figure) for installing a check valve. Here, for ease of description, the L-shaped thin-walled member located on the inner side is named the first L-shaped thin-walled structure 10a, and the L-shaped thin-walled member located on the outer side is named the second L-shaped thin-walled member 10b. Here, the first L-shaped thin-walled member 10a and the second L-shaped thin-walled member 10b have the same structure, and the "first" and "second" here are only used to distinguish the inside and the outside.

Embodiment 2

[0058] Figure 5a to Figure 5d , Is a schematic cross-sectional view of the forming process of the vertical shared exhaust passage provided in the second embodiment of the present invention. This embodiment also takes the vertical shared exhaust duct molding between two floors in a residence as an example for description. The molding processes of other floors are the same as in this embodiment, and will not be described in detail here. Moreover, this embodiment is described by taking as an example that the exhaust ducts in each floor are formed by butting and forming a first L-shaped thin-walled structure 10a and a second L-shaped thin-walled member 10b.

[0059] Figure 5a , The first L-shaped thin-walled member 10a is attached to the two wall surfaces 22 of the internal corner 20 of the room on the lower floor. In order to ensure the reliability of the close installation, the two outer wall surfaces of the first L-shaped thin-walled member 30a and the two wall surfaces 22 of th...

Embodiment 3

[0066] Image 6 , Is a longitudinal cross-sectional view of the vertical shared exhaust passage provided in the third embodiment of the present invention. In this embodiment, the exhaust duct on each floor is formed by butting two first L-shaped thin-walled members and two second L-shaped thin-walled members. In this way, compared to the first embodiment, the weight of each L-shaped thin-walled member is lighter, and it is easier to handle and install. Here, one floor is taken as an example for description, and the other floors are the same, so I won’t repeat them here. When forming the exhaust duct of the floor, first perform step S1, first fix the first first L-shaped thin-walled member 10a, and then perform step S2, that is, fix the first first L-shaped thin-walled member 10a Butt the first second L-shaped thin-walled member 10b, then repeat step S1, superimpose the second first L-shaped thin-walled member 10a on the first first L-shaped thin-walled member 10a, and finally ...

Abstract

The invention relates to the technical field of residential shared exhaust ducts, in particular to a forming process for vertical shared exhaust ducts, and the forming process for vertical shared exhaust ducts provided by the invention is particularly suitable for large-section exhaust ducts of high-rise and super high-rise residential buildings. The forming method includes the following process steps: a first L-shaped thin-wall member is first fixed closely on two wall surfaces at a reserved hole on the floor slab of a room inside corner, the first L-shaped thin-wall member is externally connected with a second L-shaped thin-wall member, and the first L-shaped thin-wall member and the second L-shaped thin-wall member are connected to define an exhaust duct. In the invention, the method is adopted to divide a thin-wall duct into the two L-shaped thin-wall members, the weight of each L-shaped thin-wall member is reduced by a half, and thereby labor intensity is decreased in the process of loading, unloading and installation; the L-shaped thin-wall members can be stacked, so transportation cost is reduced greatly; in the process of installation, the broken first L-shaped thin-wall member clinging to the wall surfaces of the inside corner can be easily repaired, and the joints between the ends of the upper member and the lower member can be easily sealed.

Description

Technical field [0001] The invention relates to the technical field of residential shared exhaust ducts, and more specifically, to a molding process of a vertical shared exhaust duct. Background technique [0002] There are currently two molding processes for vertical shared exhaust ducts used in residential buildings. One is to superimpose a thin-walled tube with a closed cross-section through a predetermined hole on the floor at the inner corner of the room (this closed type) The thin-walled tube can be formed as a whole at one time during production, or it can be produced first and then assembled and closed again.) The other is a thin-walled component with an open cross-section through the floor at the inner corner of the room. The opening is enclosed and superimposed with the inner corner wall. [0003] For the first vertical shared exhaust duct molding process, although it seems simple, just superimpose each thin-walled tube, but the actual molding has the following defects: ...
