Abstract
The utility model discloses a pre-buried straight joint of a water drain pipe, which comprises a straight pipe, wherein the outer wall of the straight pipe is provided with a circle of convex rings which are connected to form a whole; the outer wall of the lower part of the straight pipe is provided with at least one outwards-extending fixing foot; and the fixing foot is provided with a nail hole. Since the outer wall of the straight pipe is provided with a circle of convex rings which are connected to form a whole, when the pre-buried straight joint is pre-buried in a cast-in-place concrete floor slab, the convex rings of the pre-buried straight joint are embedded in the cast-in-place concrete floor slab, are integrated with the straight pipe, and have no contact surfaces, so the leakage problem of the existing pre-buried straight joint of the water drain pipe can be completely avoided; and since the upper surfaces and the lower surfaces of the convex rings are provided with grooves, the anti-seepage effect can be further improved. The straight pipe is provided with the fixing foot, so when a template is mounted, the pre-buried straight joint of the water drain pipe can be fixed on the template of the cast-in-place concrete floor slab by using a nail and can be pre-buried while the concrete floor slab is cast in place, and a mounting hole has no need to be reserved before the pre-buried straight joint of the water drain pipe is mounted, and thereby the construction process is simplified.
Description
Technical field
The utility model belongs to water-drainage tube part, is specifically related to the pre-buried straight joint of a kind of gutter.
Background technology
Building will be installed pre-buried straight joint usually in the drainage pipe construction, gutter is enclosed within installing and locating in the pre-buried straight joint again.The pre-buried straight joint of existing gutter as shown in Figure 1, comprises a straight tube 1 and the rubber seal ring 2 that is enclosed within on its outer wall.There is following problem in the pre-buried straight joint of this gutter: the one, and construction is complicated, when cast-in-place concrete floor, to reserve installing hole earlier, establish template and the pre-buried straight joint of gutter then on the installing hole of cast-in-place concrete floor, concreting A is fixed on the pre-buried straight joint of gutter on the cast-in-place concrete floor again; The 2nd, barrier properties is bad, the straight tube 1 of the pre-buried straight joint of gutter and seal ring 2 are two independently parts, and material is also different, contact surface between them can because of the surface of when construction scratch straight tube 1 or in use two parts be subjected to the weather Temperature Influence that different deformation takes place to produce the gap, cause seepage.
The utility model content
The purpose of this utility model is to provide a kind of can effectively prevent seepage, simplifies the pre-buried straight joint of gutter of construction technology.
The technical scheme that realizes the utility model purpose is: the pre-buried straight joint of gutter comprises a straight tube, the outer wall of straight tube is provided with the bulge loop that a circle is connected as a single entity, the bottom outer wall of described straight tube is provided with the fixing feet that at least one is stretched to the outer, and fixing feet is provided with the nail hole.
The one side or the upper and lower surface of described bulge loop are provided with groove.
Described fixing feet is movably arranged on the outer wall of straight tube bottom.
Adopt the pre-buried straight joint of gutter of said structure, owing on the straight tube outer wall, be provided with the bulge loop that a circle is connected as a single entity, after being embedded in the cast-in-place concrete floor, its bulge loop is embedded in the cast-in-place concrete floor, bulge loop and straight tube one do not have contact surface, and the leakage problems that can avoid the pre-buried straight joint of existing gutter to exist fully is provided with groove on bulge loop, can increase the contact surface of bulge loop and cast-in-place concrete floor, further improve anti-seepage effect.Fixing feet is set on the straight tube can be fixed on the pre-buried straight joint of gutter on the template of cast-in-place concrete floor with nail when mounting template, simultaneously pre-buried when cast-in-place concrete floor, do not need to reserve earlier the installing hole pre-buried straight joint that fixes a drainpipe again, simplified construction technology.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the schematic diagram of the existing pre-buried straight joint of gutter.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is a different structure schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the pre-buried straight joint of gutter comprises a straight tube 1, and the outer wall of straight tube 1 is provided with the bulge loop 3 that a circle is connected as a single entity, and the bottom outer wall of described straight tube 1 is provided with four fixing feet 5 of stretching to the outer, and fixing feet 5 is provided with nail hole 4.
In cast-in-place concrete floor when construction, hammer in the template 7 by the nail hole 4 on the fixing feet 5 with nail 6 earlier the pre-buried straight joint of gutter fixed, and concreting is more once finished the installation of the pre-buried straight joint of gutter and fixed.
Present embodiment as shown in Figure 4, be to establish groove 8 on the upper and lower surface (perhaps one side) with described bulge loop 3, and described fixing feet 5 is movably arranged on the outer wall of straight tube 1 bottom, the root of fixing feet 5 is designed to bayonet socket 9 and is stuck on the holder 10 that is located on straight tube 1 outer wall, fixing feet 5 can be assemblied in holder 10 easily, or takes off from holder 10.
Fixing feet 5 can also adopt to peg graft and wait other common mode to be movably arranged on the outer wall of straight tube 1 bottom.
Claims (3)
1. the pre-buried straight joint of gutter comprises a straight tube, it is characterized in that the outer wall of described straight tube is provided with the bulge loop that a circle is connected as a single entity, and the bottom outer wall of described straight tube is provided with the fixing feet that at least one is stretched to the outer, and fixing feet is provided with the nail hole.
2. the pre-buried straight joint of gutter according to claim 1 is characterized in that the one side of described bulge loop or upper and lower surface are provided with groove.
