Description

Hanging-free rubber water stop ring

Technical Field

The utility model relates to a drainage accessory in building or structure, concretely relates to exempt from to hang rubber seal ring.

Background

In the construction process of building decoration engineering, when sewer pipes of toilets, kitchens, balconies and other parts penetrate through a concrete floor slab, pre-buried water stop sleeves are installed in the floor slab according to design requirements, and holes required by subsequent pipeline installation are reserved. The traditional process is that a water-stopping steel sleeve is adopted, concrete is embedded and fixed when being poured on a floor, then a pipeline is installed, and a joint part between the pipeline and the sleeve is subjected to secondary molding and secondary grouting treatment. The whole installation process has higher requirements on the construction process, the problem of water leakage is easily caused at the joint part, the difficulty of repair is high, labor and materials are wasted, the water leakage problem cannot be thoroughly solved, and the method belongs to the common fault in the application field of building construction.

The utility model aims at providing a sealing performance is strong, construction installation is simple and direct, low cost, weatherability is good, long service life exempt from to hang rubber seal ring.

In order to realize the technical purpose, the utility model discloses a technical scheme as follows: the utility model provides a hang-free rubber seal ring, includes seal ring body, interior seal ring, outer seal ring and spacer, interior seal ring is located the bottom medial surface of seal ring body, outer seal ring is located the upper end lateral surface of seal ring body, outer seal ring lateral surface evenly sets up the spacer, seal ring body, interior seal ring, outer seal ring and spacer integrated into one piece, the middle part of interior seal ring is equipped with the through-hole, be equipped with the fixed hole of nail on the spacer.

Preferably, the number of the positioning pieces is 4, and the positioning pieces are uniformly distributed along the circumferential direction of the outer water stop ring.

Preferably, the outer side surface of the water stop ring body is uniformly provided with rough surface salient points.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the utility model has the advantages of simple construction and installation, accurate positioning, no secondary molding, no secondary grouting, shortened construction period, reduced cost, and greatly improved integral sealing performance of the sleeve water stop ring and the drain pipe;

(2) the utility model is made of rubber, and has low cost, good weather resistance, acid and alkali resistance and long service life;

(3) the utility model discloses the installation location is accurate convenient, and is big with coefficient of friction between the cast in situ concrete, forms the tight contact through interior stagnant water ring between stagnant water ring body and the sewer pipe simultaneously, prevents promptly that the sewer pipe from producing and removes the dislocation, avoids follow-up piping erection to fix a position once more, has played the effect of stagnant water leaking stoppage again.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-3, a hanging-free rubber water stop ring comprises a water stop ring body 4, an inner water stop ring 1, an outer water stop ring 2 and a positioning sheet 3, the inner water stop ring 1 is positioned on the inner side surface of the bottom end of the water stop ring body 4, the outer water stop ring 2 is positioned on the outer side surface of the upper end of the water stop ring body 1, the outer side surface of the outer water stop ring 2 is uniformly provided with 4 positioning sheets 3 along the circumferential direction, the water stop ring body 4, the inner water stop ring 1, the outer water stop ring 2 and the positioning sheets 3 are integrally formed by rubber, the cost is low, the weather resistance is good, the acid and alkali resistance is realized, the service life is long, the middle part of the inner water stop ring 1 is provided with a through hole, a sewer pipe passes through the through hole to be tightly matched with the inner water stop ring 1, the fixing plate 3 is provided with a nail fixing hole 5, the outer side surface of the water stop ring body 4 is uniformly provided with a pitted surface convex point, and the bottom surface of the inner water stop ring 1 is also uniformly provided with a pitted surface convex point.

In this embodiment, the height of the water stop ring body 4 is 40mm, and the wall thickness of the water stop ring body 4 is 2 mm; the aperture of the through hole of the inner water stop ring 1 is 80mm, the diameter of the inner water stop ring 1 is 160mm, and the thickness of the inner water stop ring 1 is 2 mm; the internal diameter of outer seal ring 2 is 164mm, and the external diameter is 194mm, and thickness is 3mm, and this application uses in the reality, can adopt different specifications in according to actual need.

The hanging-free rubber water stop ring of the utility model is of a cylindrical structure, when in installation, a PVC sleeve 8 with the outer diameter of 160mm and the height of 100mm is inserted into the hanging-free rubber water stop ring and positioned on the upper surface of the inner water stop ring 1, at the moment, the PVC sleeve 8 is tightly fixed on the longitudinal inner wall of the whole rubber water stop ring into a whole, the axis of the hanging-free rubber water stop ring is positioned, 4 nail fixing holes 5 of a positioning piece 3 are fixed on a template according to cross lines by fixing long nails, the upper end of the hanging-free rubber water stop ring is sealed by plastic gummed paper, concrete 7 is filled until the height of the concrete 7 is flush with the upper end of the PVC sleeve 8, whether the hanging-free rubber water stop ring has displacement deformation or blockage is observed, if a problem is found, the hanging-free rubber water stop immediately and the concrete 7 is repaired before the concrete 7 is solidified, the template and the plastic gummed paper are removed after the concrete 7 is solidified, a PVC pipeline 9 is inserted into, the upper end of sewer pipe 9 is less than the height of PVC sleeve pipe 8 upper end, this moment internal water stop ring 1 cramps sewer pipe 9, play the location, waterproof impervious effect, fill concrete 7 between sewer pipe 9 and the PVC sleeve pipe 8, this concrete 7 and the high parallel and level of sewer pipe 9, treat that sewer pipe 9 is fixed the back lead to water experimental can, whole installation labour saving and time saving, high efficiency is practical, exempt from to hang rubber water stop ring and concrete 7 on every side after the pouring and can become even whole, the phenomenon of difficult appearance fracture reaches effectual stagnant water effect.

The utility model has the advantages of simple construction and installation, accurate positioning, no secondary molding, no secondary grouting, shortened construction period, reduced cost, and greatly improved integral sealing performance between the sleeve water stop ring and the sewer pipeline 7; the utility model discloses the installation positioning is accurate convenient, and the coefficient of friction is big between pitted surface bump of the lateral surface of stagnant water ring body 4 and cast in situ concrete 7, forms the close contact through interior stagnant water ring 1 between stagnant water ring body 4 and the sewer pipe 7 simultaneously, prevents promptly that the sewer pipe from producing and removes the dislocation, avoids follow-up piping erection to fix a position once more, has played the effect of stagnant water leaking stoppage again.
