Branch drain percolation-proof built-in fitting
Technical field
The utility model relates to a kind of branch drain percolation-proof built-in fitting, and it mainly is located in the drainage channel (not comprising floor drain) of washroom or occasions such as kitchen or balcony, is used for upper and lower branch drain is connected.
Background technology
In construction work, the seepage problem of draining tube edge (as the washroom) is a kind of common quality defect, and the owner complains the ratio height, engineering later period maintenance trouble and expense height.
Summary of the invention
In order to solve existing in prior technology the problems referred to above, the utility model provides a kind of branch drain percolation-proof built-in fitting, and it can play percolation-proof effect preferably.
The technical solution of the utility model is as follows: a kind of branch drain percolation-proof built-in fitting, it comprises the pipe box that is used for connecting branch drain and following branch drain, it is characterized in that: the inner tubal wall of pipe box is provided with the interior anti-mouth of annular socket joint of upper orifice that is used for being socketed in down branch drain.
When installing and using, pipe box is embedded in the drainage channel of washroom or occasions such as kitchen or balcony, the lower nozzle of branch drain is placed in the inner tubal wall on pipe box top, the upper orifice of branch drain is placed between the inner tubal wall and the anti-mouth of socket joint of pipe box bottom.During draining, the water in the last branch drain can flow into down in the branch drain fully like this, can effectively avoid the water of seam crossing to be penetrated on the hypomere tube wall of pipe box and causes exosmosing.
In addition, the utility model technique scheme has also been done following improvement:
Go up water in the branch drain for further guiding and flow into smoothly down in the branch drain, be the cambered surface transition between the tube wall that described socket joint is anti-mouthful and the inner tubal wall of pipe box and be connected.
For the further percolation-proof effect that improves the utility model branch drain percolation-proof built-in fitting, and built-in fitting can better be combined with outside cast-in-situ concrete, the outer tube wall of described pipe box is provided with the notch wing ring that blocks water up.The described wing ring that blocks water not only can increase built-in fitting and outside concrete bonded area, strengthen both adhesions, built-in fitting can better be combined with outside cast-in-situ concrete, but also the water resistance in a spot of leveling layer can be ended on the wing ring that blocks water, thereby further improve the percolation-proof effect of built-in fitting.
In order to strengthen the stability and the anti-destructive of the wing ring that blocks water, and further improve the effect that combines of built-in fitting and outside cast-in-situ concrete, be provided with wing ring between the bottom surface of the described wing ring that blocks water and the outer tube wall of pipe box and support.
For the water stop function of the wing ring of further strengthening blocking water with improve the effect that combines of built-in fitting and outside cast-in-situ concrete, the described wing ring that blocks water is interior to be divided into two ring grooves by annular lip.
For the water stop function of the wing ring of further strengthening blocking water, the shape of the external annulus of the described wing ring that blocks water is truncated inverted cone shape.
In order further to guarantee the percolation-proof function of built-in fitting, the tube wall that the link of described block water wing ring and pipe box and socket joint are anti-mouthful and the link of pipe box are positioned at the sustained height position of pipe box.
In order further to increase built-in fitting and outside concrete bonded area, strengthen adhesion, pipe box can be combined completely with cast-in-situ concrete, the following pipe box outer wall of wing ring that blocks water is a frosted pipe wall, the above pipe box outer wall of wing ring that blocks water is the smooth pipe wall.
For further fixedly built-in fitting, prevent that displacement from appearring in built-in fitting when disturbing concrete, the outer tube wall bottom of described pipe box is provided with the fixing feet that extends radially outwardly, and fixing feet is provided with vertical fixing hole.
For stability and the anti-destructive that strengthens fixing feet, be provided with the fixing feet stretching structure between the upper side of described fixing feet and the outer tube wall of pipe box.
Compared to prior art, the utlity model has following advantage: (1) low price, easy to make, can adopt plastic pipe to make; (2) easy to install, only need be installed in built-in fitting on the template by fixing hole with iron nail and get final product; (3) percolation-proof effect is good, cooperating of wing ring can accomplish very percolation-proof with blocking water for anti-mouthful by pipe box and socket joint, thereby can avoid the maintenance trouble in engineering later stage and the maintenance cost of great number.

Fig. 1 is an example structure schematic diagram of the present utility model.
Number in the figure explanation: 1-smooth pipe wall, the 2-wing ring that blocks water, 3-frosted pipe wall, the 4-fixing feet, anti-mouthful of 5-socket joint, 6-wing ring supports, 7-annular lip, 8-fixing hole, 9-fixing feet stretching structure.
The specific embodiment
Below in conjunction with Figure of description and specific embodiment the utility model content is elaborated:
Be illustrated in figure 1 as a kind of branch drain percolation-proof built-in fitting that the utility model provides, it comprises the pipe box that is used for connecting branch drain and following branch drain, it is characterized in that: the inner tubal wall of pipe box is provided with the interior anti-mouth 5 of annular socket joint of upper orifice that is used for being socketed in down branch drain.
Being the cambered surface transition between the tube wall that described socket joint is anti-mouthful 5 and the inner tubal wall of pipe box is connected.
The outer tube wall of described pipe box is provided with the notch wing ring 2 that blocks water up.
Be provided with wing ring between the bottom surface of the described wing ring 2 that blocks water and the outer tube wall of pipe box and support 6.
Be divided into two ring grooves by annular lip 7 in the described wing ring 2 that blocks water.
The shape of the external annulus of the described wing ring 2 that blocks water is truncated inverted cone shape.
The link of the tube wall of anti-mouthful 5 of the link of wing ring 2 and pipe box and socket joint and pipe box of blocking water is positioned at the sustained height position of pipe box.
The pipe box outer wall of wing ring more than 2 that block water is smooth pipe wall 1, and the pipe box outer wall of wing ring below 2 that block water is frosted pipe wall 3.
The outer tube wall bottom of described pipe box is provided with the fixing feet 4 that extends radially outwardly, and fixing feet 4 is provided with vertical fixing hole 8.
Be provided with fixing feet stretching structure 9 between the upper side of described fixing feet 4 and the outer tube wall of pipe box.
During concrete enforcement, can be with reference to following parameter designing:
The described wing ring 2 that blocks water can stretch out about distance pipe box bottom 45mm place, the wing ring support 6 of the about 5mm * 5mm of play band, on the two dark ring grooves of 7mm of having an appointment, be used for forming the height about 52mm of last eaves bottom the pipe box of the annular lip 7 of two ring grooves.
The outer tube wall of pipe box bottom can be provided with four fixing feet 4, each fixing feet 4 can be respectively with fixing hole and and fixing feet stretching structure 9 of an about 4mm of diameter.
The inner tubal wall of pipe box internal diameter from top to bottom is identical, and size equates with the last branch drain that needs to install and the external diameter of following branch drain.
The wall thickness of pipe box is with reference to the GB of corresponding specification plastic pipe wall thickness.
The wall thickness of wing ring 2 of blocking water can be slightly less than the wall thickness of pipe box.
The wall thickness of fixing feet 4 that is arranged at the outer tube wall bottom of pipe box can be greater than the wall thickness of pipe box.
Built-in fitting described in the utility model and with it matching used upper and lower branch drain all preferably make with plastic pipe, also can adopt the pipe fitting of other material to make as required certainly.
