Detailed Description
The following combines specific drawings to further explain the utility model discloses an upper and lower floor flue root leak protection water structure in detail.
As shown in fig. 1 and 2, a water leakage prevention structure for the root of a flue of an upper floor and a lower floor comprises an embedded part 1 and a connecting part 2, when a construction unit is used for constructing a floor slab, the installation position of the flue 3 is determined firstly, then the embedded part 1 is embedded in the floor slab 4 through cement and the like, protrusions 11 are arranged around the upper end surface of the embedded part 1, grooves 21 are arranged around the lower end surface of the connecting part 2, the protrusions 11 are matched with the grooves 21, and during installation, a cement layer (not shown in the figure) is arranged between the protrusions 11 and the grooves 21 to firmly fix the connecting part 2 and the embedded part 1 together to play a role of preventing water leakage.
As shown in fig. 3 and 4, the cross section of the embedded part 1 is square, a square through hole 12 is formed in the longitudinal middle of the embedded part 1 and used for installing the flue 3, a square flange 13 is arranged above the inner wall of the embedded part 1, the square flange 13 and the embedded part 1 are integrally formed, and during installation, the upper portion of the flue 3 is supported on the square flange 13, so that the flue 3 is stably and firmly installed and is convenient to install.
When the embedded part is installed, the groove 21 is filled with cement, so that a cement layer is formed, and the embedded part 1 and the connecting part 2 are firmly connected.
As shown in fig. 5 and 6, the transverse section of the connecting piece 2 is square, the longitudinal middle part of the connecting piece 2 is provided with a square through hole 22 for installing the flue 3, at least two side surfaces of the connecting piece 2 are provided with water-retaining ridges 23, the side surface with the water-retaining ridges 23 is of a step-shaped structure, when the flue 3 is installed, the lower part of the flue 3 is propped against the inner side of the water-retaining ridges 23 of the connecting piece 2, so that the waterproof and smoke-channeling-preventing effects are further achieved, meanwhile, the flue can be conveniently installed, and the water-retaining ridges 23 and the connecting piece 2 are integrally formed. It should be understood that, the utility model discloses a flue 3 installation completion back, connecting piece 2 is leaned on two reentrant corners of wall and need the hanging net to plaster to prevent the infiltration. When two side surfaces of the flue 3 are installed against a wall, the connecting pieces 2 (shown in fig. 7 and fig. 2) with the water retaining ridges 23 arranged on the two side surfaces are usually selected, and the two side surfaces with the water retaining ridges 23 are arranged adjacently, and when the connecting pieces are installed, the two side surfaces without the water retaining ridges are directly installed against the wall; when one side surface of the flue 3 is installed against a wall, three connecting pieces 2 (shown in figure 8) with the water retaining ridges 23 arranged on the side surfaces can be selected, and when the flue is installed, the side surfaces without the water retaining ridges are directly installed against the wall; when the flue 3 is not installed against a wall, the connecting piece 2 provided with the water retaining ridges 23 on four sides is directly selected (as shown in fig. 1 and 6).
