Embodiment 1

[0044] figure 1 , is a top view of the vertical common exhaust duct provided by Embodiment 1 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. Viewed from its cross section, the vertical shared exhaust duct is formed by the butt joint of two L-shaped thin-walled members, one of which is L-shaped An air inlet (not shown in the figure) is provided on the thin-walled member for installing a check valve. Here, for the convenience of description, the inner L-shaped thin-walled member is named as the first L-shaped thin-walled member 10a, and the outer L-shaped thin-walled member is named as 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 words "first" and "second" here are only used to distinguish the inner side from the outer side.

Embodiment 2

[0058] Figure 5a to Figure 5d , is a cross-sectional schematic diagram of the forming process of the vertical common exhaust channel provided by Embodiment 2 of the present invention. This embodiment also takes the forming of the vertical shared exhaust duct between two floors of a residence as an example for illustration. The forming process of other floors is the same as this embodiment, and will not be described in detail here. Moreover, this embodiment is described by taking an example in which the exhaust ducts on each floor are butt-jointed and formed by a first L-shaped thin-walled member 10a and a second L-shaped thin-walled member 10b.

[0059] Figure 5a , first lean against the first L-shaped thin-walled member 10a on the two wall surfaces 22 of the inner corner 20 of the room on the lower floor. In order to ensure the reliability of the adjacent installation, the two outer walls of the first L-shaped thin-walled member 30a and the two walls 22 of the inner corne...

Embodiment 3

[0066] Figure 6 , is a longitudinal cross-sectional view of the vertical shared exhaust duct provided by Embodiment 3 of the present invention. In this embodiment, the exhaust duct on each floor is formed by butting two first L-shaped thin-walled components and two second L-shaped thin-walled components. In this way, compared with the first embodiment, the weight of each L-shaped thin-walled member is lighter, and it is easier to transport and install. Here, one floor is taken as an example for illustration, and the other floors are the same, so details are not repeated here. When forming the exhaust duct on this 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 again The first second L-shaped thin-walled member 10b that is docked, and then repeat step S1, superimpose the second first L-shaped thin-walled member 10a on the first first L-shaped thin-w...

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 shared exhaust ducts for residential buildings, and more specifically relates to a forming process for vertical shared exhaust ducts. Background technique [0002] There are two existing forming techniques for the vertical shared exhaust duct used in residential buildings. One is to superimpose thin-walled tubes with closed cross-sections through the preset holes on the floor at the corner of the room (this closed type The thin-walled tube can be formed as a whole at one time during production, or the plate can be produced first and then assembled and closed for the second time), and the other thin-walled member with an open cross section passes through the preset on the floor at the corner of the room The hole is formed by enclosing and superimposing the wall of the inner corner. [0003] For the first molding process of vertically sharing the exhaust channel, although it seems simple, it is enough to s...
