Abstract

The utility model discloses one and run through concrete floor waterproof construction, it comprises technique hole reserved on flooring, and the pea gravel concreten tamped after pipe laying in technique hole.Described technique hole is not waited by least two joint sizes and coaxial conical bore part is socketed to form, the perpendicular conical bore put is up big and down small structure, the large end of conical bore of next joint stretches in a pitch circle taper hole, and two conical bore suit places are linked into an integrated entity by low inside and high outside incline bench.The utility model is after pipe laying in technique hole is fixing, can tamp pea gravel concreten between technique hole and pipeline, pea gravel concreten solidifies the built-in incline bench of rear formation, can stop the radial and axial contraction of thin concrete, also form mazy type water sealing structure, guarantee that flooring is non-leakage.The utility model both can be used as the waterproof construction that water supply pipeline runs through concrete floor, was also suitable as the waterproof construction worn other pipeline such as wireway, air channel and run through concrete floor.

Description

Pipeline runs through concrete floor waterproof construction

Technical field

The utility model relates to a kind of house floor gap waterproof construction, and specifically, the utility model relates to a kind of pipeline and runs through concrete floor waterproof construction.

Background technique

In construction engineering during concreting flooring, to reserve by design attitude the technique hole kept supplying drainage pipeline and pass, after upper and lower conduit road is in place, tamp with pea gravel concreten the technique hole filling vacancy more afterwards.Technique hole majority reserved in construction engineering is cylindrical hole, also accidental up big and down small cone-shaped hole, and the technique hole structure of these shapes is simple, making is easy, can accomplish the vacancy between effective plugging technology hole and pipeline after tamping.But, the technique hole of prior art is because lacking radial limit structure and axial waterproof construction, so in reality residential building flooring on reserved technique hole tamp rear majority and there is seepage problem, its reason is accessible contraction when tamping the pea gravel concreten solidification filled the later stage, pea gravel concreten and concrete floor and tubing connection is caused to there is micro-gap, once flooring ponding, water is seeped into downstairs along micro-gap, and excessive infiltration must cause neighbourhood's dispute.

Model utility content

There is seepage problem mainly for prior art in the utility model, proposes the pipeline that a kind of structure is simple, construction is easy, leakage-proof effect is good and run through concrete floor waterproof construction.

The utility model is achieved through the following technical solutions technical goal.

Pipeline runs through concrete floor waterproof construction, and it comprises technique hole reserved on flooring, and the pea gravel concreten tamped after pipe laying in technique hole.Its improvements are: described technique hole is not waited by least two joint sizes and coaxial conical bore part is socketed to form, the perpendicular conical bore put is up big and down small structure, the large end of conical bore of next joint stretches in a pitch circle taper hole, two conical bore suit places are positioned at middle part, and both are linked into an integrated entity by low inside and high outside incline bench.

In said structure, cone angle alpha=30 in technique hole °~ 60 °.On technique hole, the large end radius of next pitch circle taper hole of small end radius ratio of a pitch circle taper hole is large, and both semidiameter B=10mm ~ 30mm, the large end of next pitch circle taper hole stretches in a pitch circle taper hole small end, coincidence amount h=15mm ~ 25mm.

The utility model compared with prior art, has following good effect:

1, technique hole is connected to form by the good luck axle of conical bore one of different size, and structure is simple, and the demoulding is easy, does not increase difficulty of construction;

2, pea gravel concreten tamps between technique hole and pipeline, and the incline bench solidifying rear formation plays and stops the radial and axial contraction of pea gravel concreten, significantly reduces the gap of flooring really, between pipeline and pea gravel concreten, is conducive to leakage proof;

3, connected by incline bench between the conical bore saving fit up and down, after the pea gravel concreten tamped solidifies, form mazy type water sealing structure, leakage proof is effective.

Fig. 3 is incline bench structure enlarged diagram in Fig. 2.

Fig. 4 is the utility model structural profile schematic diagram, and this figure shows the embodiment being made up of flooring waterproof construction 4 joint phase fit conical bores.

Embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.

Embodiment 1

Pipeline shown in Fig. 1 runs through mixed Tulou face waterproof construction, and it comprises technique hole 1.1 reserved on flooring 1, and the pea gravel concreten 2 tamped after mounting pipe 3 in technique hole 1.1.The present embodiment is used for the waterproof construction that residence building water supply pipeline runs through concrete floor, supporting pipeline 3 external diameter 32mm.When building flooring 1 by technique hole 1.1 reserved shown in Fig. 2, because flooring 1 thickness is 120mm, belong to general thickness.This technique hole 1.1 is not waited by two joint sizes and coaxial conical bore part is socketed to form, and the perpendicular two pitch circle taper holes put are up big and down small structure.Be in the long 60mm of conical bore of next joint, cone angle 40 °, small end radius 25mm, large end radius is about 46.8mm.Be in the long 75mm of conical bore of a joint, cone angle 45 °, the large end radius of conical bore going up next joint of small end radius ratio of a pitch circle taper hole is as shown in Figure 3 large, both semidiameter B=10mm.The large end of conical bore of next joint extend in a pitch circle taper hole, coincidence amount h=15mm, and two conical bore suit places are positioned at middle part, and both are linked into an integrated entity by low inside and high outside incline bench.Technique hole 1.1 in the utility model is basic components, and it is connected to form by the good luck axle of conical bore one of different size, and flooring 1 builds the rear demoulding easily, does not increase difficulty of construction.After the pipeline 3 installed in technique hole 1.1 is fixing, pea gravel concreten 2 can be tamped between technique hole 1.1 and pipeline, pea gravel concreten 2 solidifies the built-in incline bench of rear formation, play and stop the 2 radial and axial contractions of the solidifying soil of microlith mud, gap between remarkable reduction flooring 1 and pea gravel concreten 2, is conducive to leakage proof.Be on the other hand upper and lower fit conical bore between connected by incline bench, after the pea gravel concreten tamped solidify, form mazy type water sealing structure, guarantee non-leakage.

Embodiment 2

Fig. 4 is the utility model embodiment 2 structural representation, and show in figure that auxiliary hole 1.1 is not waited by 4 joint sizes and coaxial conical bore part is socketed to form, this embodiment is used for the thicker occasion of flooring 1.The present embodiment because of between technique hole 1.1 and concrete junction be provided with 3 incline benches, be that is provided with 3 road mazy type water sealing structures, its water leakage performance is further strengthened.In addition other good effect is identical with embodiment 1.
