Abstract
The invention discloses a site cast sealed water-stop joint, relating to a water pipe connector and comprising a hollow water pipe connector (1), wherein a bottom edge (2) is arranged on the external peripheral wall at the bottom of the water pipe connector (1) and is provided with a mounting hole (3); a water-stop step (4) is arranged on the external peripheral wall of the water pipe connector (1) above the bottom edge (2); the step face of the water-stop step (4) is provided with at least one water-stop ring (5), and the water-stop step (4) is provided with a groove matched therewith; and a double-layer plug-in bottom bell mouth is arranged below the water-stop step. The water-stop ring is fixed on the water-stop step on the external surface of the water pipe connector, and simultaneously a dermatoglyph processing section on the external surface of the water pipe connector between the water-stop step and the part from the water-stop step to the bottom edge can ensure the waterproof effect of the water-stop joint and a pre-contact surface, thereby effectively reducing the possibility of leakage due to long time use after installation, and moreover, a site cast fixed hole on the bottom edge can maximally reduce size error when in installation.
Description
Technical field
The present invention relates to a kind of water pipe adapter, specifically a kind of site cast sealed water-stop joint.
Background technique
In building engineering construction, often need be in the floor flooring pipe laying joint.Present way normally, first reserving hole in work progress, treat that pipeline installs after, with concrete reality is watered in the slit between pipeline and the hole wall again.But produce the crack because concrete shrinkage and creep can make around the pipeline, in case run into ponding arranged in the room, water will be along the crack seepage down.This has directly influenced the normal use in house, brings great inconvenience also for people's life.
At present, the sealing joint that is directed to above-mentioned situation has specially been arranged on the market, a kind ofly by periphery below water pipe adapter one circle sealing bed die is set, and the weep hole that on the water pipe adapter wall of bed die and water pipe adapter joint, inwardly offers at least more than one, to solve the ponding leakage problems between pipeline and the hole, leak preventing effect is better.But, when using this water cut-off device, still need be in work progress reserving hole, after being installed in the sealing joint in this pipeline hole, again with concrete with around the sealing joint and to water puddling between the hole wall real, the installation process complexity; Another kind is the cast-in-place sealing joint of making, when mounted no longer need be in work progress reserving hole, and sealing pipe joint scapegoat and the moulding of cast-in-place plate disposal pouring, but this kind structure is more single, the stagnant water effect instability, long-time use is still leaked easily.
Summary of the invention
The objective of the invention is to solve above-mentioned deficiency, provide a kind of stagnant water effect good, simple in structure site cast sealed water-stop joint.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
Site cast sealed water-stop joint of the present invention, comprise the water pipe adapter of a hollow, the bottom periphery wall of water pipe adapter is provided with feather edge, feather edge is provided with mounting hole, water pipe adapter periphery wall above the feather edge is provided with the sealing step, at least one water stop ring is arranged on the table top of sealing step, and on the sealing step groove that matches with it is arranged, there is the bottom surface bellmouth of double-deck interpolation type sealing step below.
Further technological scheme is: described sealing step table top and sealing step to the water pipe adapter outer surface between the feather edge is the part of handling by dermatoglyph.
Further technological scheme is: described mounting hole is cast-in-place fixed hole.
Further technological scheme is: described feather edge is square or circle or polygonal.
Compared with prior art, the invention has the beneficial effects as follows: water stop ring is fixed on the sealing step of water pipe adapter outer surface, can improve the sealing effectiveness of water stop ring, to guarantee stagnant water effect, sealing step and the sealing step dermatoglyph treated section to the water pipe adapter outer surface between the feather edge simultaneously, can guarantee the waterproofing effect of sealing joint and pre-surface of contact, add the double-deck interpolation type bottom surface bellmouth of sealing step below, reduced effectively and the back has been installed because of the long-time possibility of leaking of using, the cast-in-place fixed hole on the feather edge can reduce the error of size when installing to greatest extent; Site cast sealed water-stop joint of the present invention is simple in structure, easy for installation simultaneously, is suitable for industrialized production, is easy to promote.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
The present invention is further elaborated below in conjunction with accompanying drawing.
As Fig. 1, shown in Figure 2, site cast sealed water-stop joint of the present invention, comprise the water pipe adapter 1 of a hollow, the bottom periphery wall of water pipe adapter 1 is provided with circular base edge 2, mounting hole 3 is set on the feather edge, mounting hole 3 is cast-in-place fixed hole, water pipe adapter 1 periphery wall above the feather edge 2 is provided with sealing step 4, two water stop rings 5 are arranged on the table top of sealing step 4, one of them water stop ring 5 is sleeved on another water stop ring 5 outsides, and two grooves that match with it are arranged on sealing step 4, described water stop ring 5 is fixed on the sealing step 4, sealing step 4 table tops and sealing step to the water pipe adapter outer surface between the feather edge is the part of handling by dermatoglyph 7, and sealing step below arranges the bottom surface bellmouth 6 of double-deck interpolation type.
