The utility model has the characteristics that and beneficial effect compared with prior art.
1, outer tube is temporarily fixed on slab form by the direct-buried pipe structure of the utility model before construction, and is used
Steel nail is fixed temporarily, then is blocked at the top of outer tube, and floorslab concrete is poured, and then carries out lower drainpipe and upper
The installation of drainpipe, the outer tube of this structure and floor one-pass molding, it is no longer necessary to hang mould, stifled hole, solve conventional discharge
Pipe-through floor slab position, the problem of needing to hang mould casting concrete.
2, the outer tube in the utility model is cast in floor, and forms one with floor, in upper drainpipe and outside
Between casing, lower drainpipe and outer tube block sealing material, this structure not only avoid residential building kitchen and toilet water pipe closure
The risk of leakage reduces repair rate, and also reduces floor plugging construction process, improves construction efficiency.
3, connection of the outer tube as upper drainpipe and outer tube is directlyed adopt in the utility model, outer tube is regularization
Component, avoid it is traditional be custom fabricated on-site wooden box, save material, artificial and cost.
Detailed description of the invention
The utility model is described in more detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram that the utility model is arranged in floor.
Fig. 2 is the outer tube of the utility model and the structural schematic diagram that is arranged on slab form.
Appended drawing reference: the upper drainpipe of drainpipe, 3-, 4- sealing material, 5- floor, the building 6- under 1- outer tube, 2-
Template die plate, 7- steel nail.
Specific embodiment
As illustrated in fig. 1 and 2, this direct-buried pipe structure includes outer tube 1, lower drainpipe 2, upper drainpipe 3 and sealing material
Material 4；The outer tube 1 is embedded in floor 5, and vertically runs through floor 5；Wherein, the bottom surface of the bottom of outer tube 1 and floor 5
Concordantly, the top of outer tube 1 exceeds the top surface of floor 5；The lower drainpipe 2 is inserted into outer tube 1 from the lower port of outer tube 1
In, the top of lower drainpipe 2 is located at the position of 5 top surface of floor or less；The upper drainpipe 3 is inserted into from the upper port of outer tube 1
In outer tube 1, and splice with lower drainpipe 2；The sealing material 4 is filled in the gap between drainpipe 3 and outer tube 1
And in the gap between lower drainpipe 2 and outer tube 1.
In the present embodiment, the top of the outer tube 1 is 50mm ~ 100mm beyond the length of 5 top surface of floor.
In the present embodiment, to prevent the installation of outer tube 1 from occurring in deviation and the concreting process of floor 5, artificially
Factor touching outer tube 1 moves；When selecting outer tube 1, outer diameter of 1 internal diameter of outer tube than lower drainpipe 2 and upper drainpipe 3
Big 10cm is convenient for activity adjustment；Spacing between the lateral wall of the i.e. described lower drainpipe 2 and the inner sidewall of outer tube 1 is 5mm；
Spacing between the lateral wall of the upper drainpipe 3 and the inner sidewall of outer tube 1 is 5mm.
In the present embodiment, the lateral surface that the outer tube 1 is located in concrete package range is hair side, makes 5 coagulation of floor
It is closely connect in native casting process with 1 surrounding of outer tube.
Certainly in other embodiments, the spacing between the lateral wall of the lower drainpipe 2 and the inner sidewall of outer tube 1 is also
It can adjust according to the actual situation, generally 4mm~6mm；The inner sidewall of the lateral wall of the upper drainpipe 3 and outer tube 1 it
Between spacing can also adjust according to the actual situation, generally 4mm~6mm.
In the present embodiment, the spacing between 5 top surface of top and floor of the lower drainpipe 2 is 50mm ~ 100mm.
In the present embodiment, the sealing material 4 is silicone sealant.

In the present embodiment, the outer tube 1 is PVC pipe.
Certainly in other embodiments, the outer tube 1 can also use PE pipe fitting or PP pipe fitting.
In the present embodiment, before the concreting of floor 5, outer tube 1 is fixed on slab form 6 by designated position
On, outer tube 1 is wrapped up in the concreting process of floor 5.When lower drainpipe 2 and upper drainpipe 3 in floor are installed, directly
It is inserted into the outer tube 1 being embedded in floor 5.Since outer tube 1 is wrapped up in the concreting of floor 5, so reducing
While later period blocks up hole cumbersome process, construction cost has been saved, has reduced infiltration hidden danger.
In the present embodiment, the material of the outer tube 1 is identical as the material of lower drainpipe 2, the material of upper drainpipe 3.
In the present embodiment, the wall thickness of the outer tube 1 is identical as the wall thickness of lower drainpipe 2, the wall thickness of upper drainpipe 3.
In the present embodiment, the thickness and coordinate of the installation dimension, wall that use bathroom ware are determined according to engineering first
Axis, then determine pre-buried behind the position of the outer tube 1；One people presses outer tube 1 on slab form 6 when pre-buried, and a people exists
The four direction of outer tube 1 nails on steel nail 7, is temporarily fixed on slab form 6, is pouring build floor 5 to prevent outer tube 1
It shifts in Concrete.
In the present embodiment, after the completion of outer tube 1 is fixed, use adhesive tape by outer tube 1 before the concreting of floor 5
Top block, prevent in concreting process, pipe in enter concrete；In the peace for carrying out lower drainpipe 2 and upper drainpipe 3
When dress, first according to the length of lower drainpipe 2, it is located at interface in outer tube 1, the installation of drainpipe is successively installed from bottom to top,
Lower drainpipe 2 is first installed and then installs drainpipe 3, the end of upper and lower drainpipe is in close contact；Upper drainpipe 3 and lower drainpipe
After 2 are installed, using sealing material 4 by the gap plugging between drainpipe and outer tube 1.
In the present embodiment, after outer tube 1 fixes, finished product protection work should be carried out, prevent in structure construction procedure and
The displacement and damage of outer tube 1 before drainpipe installation.
Above-described embodiment is not the exhaustion of specific embodiment, can also there is other embodiments, and above-described embodiment purpose exists
In illustrating the utility model, rather than the protection scope of the utility model is limited, it is all from the utility model simple change
