Abstract

The utility model relates to an improved building floor drain. An anti-seepage sealing collar and a water seepage hole are arranged on the upper part of a floor drain bowl, which are made to integration with the floor drain bowl. The anti-seepage sealing collar can prevent the water seepage which is generated by a floor drain bowl body and a floated coat. The water seepage can flow into the drainage pipeline through the water seepage hole. The utility model effectively overcomes the problem of water seepage which is generated by the existing floor drain, which is an anti-seepage floor drain of a novel.

Description

Leak-proof drain

The utility model relates to a kind of floor drain seepage control technique of building sewer.

In prior art, the infiltration of building sewer floor drain is a current builing industry problem extremely to be solved, its percolating water main cause is to be subjected to effects such as various external force and variations in temperature between floor drain bowl and floated coat and the deck, As time goes on makes binding site produce the crack gradually.When the locality is omitted water in printing, have part water may be by the crack along the floor drain leaktightness of wall of tubes to the outside, this is the attractive in appearance and life-span of crime of injuries by explosive substances to buildings and goods therein not only, brings a lot of bitter brains also for daily people's life.

The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of simple in structure and can effectively prevent the novel floor drain of percolating water.

Task of the present utility model is achieved in that the top perisporium at floor drain bowl ［ 2 ］ has infiltration hole ［ 4 ］, has one to make the water seepage prevention circle ［ 3 ］ of one with floor drain bowl ［ 2 ］ under the aperture in infiltration hole ［ 4 ］.When water oozes following time from the crack that produces between floor drain bowl ［ 2 ］ perisporium and the floated coat ［ 5 ］, stoped by water seepage prevention circle ［ 3 ］ after infiltration hole ［ 4 ］ flows into floor drain bowl ［ 2 ］ to enter the sewer pipe outflow.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.

Fig. 1 is the structural representation of anti-seepage floor drain.

1 is drain cover among the figure, and 2 is the floor drain bowl, and 3 is the water seepage prevention circle, and 4 are the infiltration hole, and 5 is floated coat, and 6 is deck.

Fig. 1 illustrates the utility model embodiment, be equipped with 2～8 infiltration holes ［ 4 ］ in floor drain bowl ［ 2 ］ top perisporium symmetry, the aperture is 2～6mm, it is the water seepage prevention circle ［ 3 ］ of 20～30mm that one width of making one with floor drain bowl ［ 2 ］ is arranged under the aperture in infiltration hole ［ 4 ］, the angle α of the plane of water seepage prevention circle ［ 3 ］ and floor drain bowl ［ 2 ］ the rim of a bowl vertical line is 60～70 °, this anti-seepage floor drain is packed into behind the drainage system of building, smear reality with cement mortar, cover drain cover ［ 1 ］, during the floor drain draining, water flows into floor drain bowl ［ 2 ］ through drain cover ［ 1 ］ and enters sewer pipe.When producing the crack between floor drain bowl ［ 2 ］ perisporium and the floated coat ［ 4 ］, may have part water oozes along the crack of floor drain bowl ［ 2 ］ perisporium down, because stretching into the floated coat area, water seepage prevention circle ［ 3 ］ increases, and a positive pitch arranged, infiltration can be deposited and ooze under continuing, when water increases, flow into floor drain bowl ［ 2 ］ by infiltration hole ［ 4 ］, discharge through drainage pipeline.Can solve the floor drain infiltration of building thus.

The utility model can effectively prevent building Odour seal seepage problem compared with prior art. The structure of anti-seepage floor drain and mounting process and original technique variation are little, and manufacturing cost does not have much raisings, are the desirable floor drains of water antiseepage under the building.

Claims

1, a kind of anti-seepage floor drain is made up of drain cover [1], floor drain bowl [2], and the top perisporium that it is characterized in that floor drain bowl [2] has infiltration hole [4], has one to make the water seepage prevention circle [3] of one with floor drain bowl [2] under the aperture in infiltration hole [4].

2, anti-seepage floor drain according to claim 1, the hole ［ 4 ］ that it is characterized in that seeping water are that the aperture is 2～6mm along 2～8 of infiltration bowl ［ 2 ］ perisporium symmetric arrangement.

3, anti-seepage floor drain according to claim 1 is characterized in that water seepage prevention circle ［ 3 ］ width is 20～30mm, and the plane of water seepage prevention circle ［ 3 ］ and the angle α of the rim of a bowl vertical line are 60～70 °.

4, anti-seepage floor drain according to claim 3 is characterized in that water seepage prevention circle ［ 3 ］, can use passing on the sewer pipe of floor.
