Abstract

The utility model discloses an embedded part of a water proof casing. The inner wall of a tube body is provided with a level check ring which is arranged along radial direction; and the rampart of an exine is provided with a level water ring, the upper tube wall and the lower tube wall are alternately provided with friction rings. The upper end of the tube body is provided with an upper check plug while the lower end of the tube body is provided with a lower check plug; the centers of the two check plugs are respectively provided with an upper screw hole and a lower screw hole, the medial axis of the upper screw hole and the medial axis of the lower screw hole are identical with the medial axis of the tube body. In construction engineering, the problem of toilet tube seepage is one of the common faults of the engineering quality. By improving the structure of the pipe fitting and arranging the check ring in the cavity of the tube rampart and the water ring and the friction rings at the external rampart, inventors solve the correlative technique problems excellently. The check ring is provided, after an upper drainage pipeline and a lower drainage pipeline are inserted respectively in an upper direction and in a lower direction, the ends respectively cling to the front surface of the check ring and the back surface of the check ring, which solves the seal problem; after the water ring and the friction rings are arranged, the bond force of the external wall of the tube body with the present floor concrete is beneficially solved and the anti-seepage ability of the casing is further increased.

Description

The water string built-in fitting

Technical field

The utility model belongs to the drainage fitting that adopts in a kind of building construction, relates in particular to a kind ofly to be embedded in the house floor in the housing construction process, is used to connect the water string built-in fitting of lower drainage pipe.

Background technology

Building construction is especially in the civic building building engineering construction, owing to locate to need to be provided with the drainage pipe of intercommunication up and down between washroom, kitchen etc., therefore, often needs pre-buried water string when watering build floor.Currently used job practices is: when building; the pre-buried rigid sleeve of elder generation; treat to reconnect lower drainage pipe behind the floor finish-drying; there is following deficiency in this method: because the rigid casing inside and outside wall is smooth shape; the one, after gutter passes this cannula cavity; can stay the slit between its rigid casing inwall and the gutter outer wall; the joint filling processing need be carried out with glow compact material and waterproofing unction in this slit in the prior art; but this gap construction quality is difficult to reach qualified requirement in practice, and the infiltration phenomenon appears in regular meeting.In addition, rigid casing outer wall and floorslab concrete junction are that tube edge also exists easy seepage problem.

Summary of the invention

For overcoming the above-mentioned deficiency of prior art, the utility model aims to provide a kind of water string built-in fitting, utilize this built-in fitting can omit stuff up a crack treatment process in the present technology, solve the problem that is easy to generate infiltration between rigid casing inwall and the gutter outer wall because of the slit, and the water resistance that strengthens rigid casing outer wall and floorslab concrete junction.

The technical scheme that realizes above-mentioned purpose is as follows: the structure of this water string built-in fitting comprises body, it is characterized in that: inboard wall of tube body is provided with the horizontal spacing ring that radially is provided with, the outer wall ring wall is provided with the horizontal stop water ring, and compartment is furnished with drag ring on the seal ring tube wall up and down.

During concrete enforcement, be provided with upper limit plug, lower limit plug on the two-port up and down at body, the center of two spacing plugs has screw, screw down, and it is consistent with the axis of body to go up the axis of screw, following screw.

During concrete enforcement, the radial thickness of body upper and lower port wall is consistent with drag ring thickness.

Beneficial effect: washroom tube edge seepage problem is one of workmanship common fault in the construction work, and the inventor is by improving fitting structure, the tube body wall inner chamber be provided with on spacing ring, the external annulus seal ring and drag ring are set after, solved the correlation technique problem well.After spacing ring is set, when last lower drainage pipe respectively from after up and down both direction inserts, its port is against the spacing ring positive and negative respectively and has solved sealing problem; After seal ring and drag ring are set, help solving the concrete adhesion stress of tube wall and cast-in-situ floor, and then improved the percolation-proof ability of water string built-in fitting.When the utility model is installed, except the tube edge leakage problems that can eliminate traditional method, also have the characteristics of saving artificial, material and improving the decorative engineering quality.

Description of drawings

Fig. 1 is the sectional structure schematic diagram of an embodiment.

The specific embodiment

Sequence number is represented respectively among Fig. 1: body 1, upper limit plug 2, last screw 3, end endless belt 4, drag ring 5, spacing ring 6, lower limit plug 7, following screw 8, seal ring 9, locating ring 10.

Among Fig. 1, the water string built-in fitting adopts plastic monoblock to make except that upper limit plug 2, lower limit plug 7, and body 1 is tubular ringwise, and spacing ring 6 is set on its inwall, and seal ring 9 is set on the outer wall, and on lower wall on the seal ring 9 drag ring 5 is set.In addition, form end endless belt 4 in the tubing wall thickening back of body two-port, to strengthen accessory intensity and integral rigidity.Upper limit plug 2, lower limit plug 7 can adopt the locating ring form that fuses with it to locate, to prevent the built-in fitting horizontal shift.

In the specific implementation, be 80-100mm according to existing job specfication general requirements construction work bathroom floor thickness, the service sleeve height should exceed deck 50mm, and the design overall height during making can be 150mm, can satisfy general civilian construction instructions for use.

According to the practical situations of engineering tubing, the internal diameter of service sleeve can be produced by the accessory requirement of 110mm, 75mm, 50mm; The spacing anti-connection degree of depth can design by 50mm; Pipe thickness can add the 0.3mm design by tubing is thick, thereby strengthens pipe fitting recoil pressure degree, and end endless belt 4 can suitably be thickeied again, to strengthen accessory intensity and integral rigidity.

The position of seal ring 9 can be arranged on the place apart from bottom 50mm, its thickness and width can be respectively 3mm, 30mm, the method to set up of drag ring 5 can be in the 100mm scope of distance bottom, every interval 5mm is provided with a drag ring 5 that protrudes tube wall 2mm, to strengthen the adhesion stress of pipe fitting outer wall and cast-in-situ concrete.

The job practices of this water string built-in fitting is as follows:

1, after engineering slab form operation is finished, unwrapping wire according to the adjacent axis of engineering, is measured the central point of pre-pipe laying immediately.

2, according to central point, with last screw 3, the following screw 8 usefulness nuts of screw rod on upper limit plug 2, lower limit plug 7 built-in fitting is positioned on the template, to prevent built-in fitting displacement (upper limit plug 2, lower limit plug 7 are provisional parts, it should be shed at last).

3, treat that concrete strength reaches 1.2Mpa after, remove screw rod, seal with plastic paper.

4, going up lower drainage pipe installs: remove and seal plastic paper, wipe interface clear, after smearing with pvc pipe bonding glue, drainage pipe (or accessory) is inserted in the pre-pipe laying, wipe the glue of extruding clear and get final product.
