CN202227694U - Embedded sleeve for concrete pouring construction of bathroom floor - Google Patents

Abstract

The utility model relates to an embedded sleeve for concrete pouring construction of a bathroom floor, which comprises an upper pipe fitting, a middle pipe fitting and a lower pipe fitting. The outer surface of the embedded sleeve is roughened, thereby increasing contact area of the sleeve and concrete and effectively blocking leakage paths. The middle pipe fitting is a bucket-shaped variable cross-section structure, and an inner inserting ring of the bucket-shaped lower portion of the middle pipe fitting is inserted into a rigid polyvinyl chloride (PVC-U) pipe (the upper end of the PVC-U pipe is installed in an inner ring groove). Even through bonding defects exist on the sleeve and the PVC pipe, leakage does not occur. The PVC embedded sleeve has high cost performance and can be manufactured according to various specifications and sizes, the construction progress is quick, and construction quality is improved.

Description

Use service sleeve in a kind of bathroom floor concrete pouring construction

Technical field

The utility model belongs to technical field of building construction, is specifically related to use service sleeve in a kind of bathroom floor concrete pouring construction.

Background technology

The traditional method of toilet drainage pipeline through-flooring construction is to stay hole to be provided, treats after the piping erection to adopt artificial molding to add the mounting method that iron wire hangs mould its shutoff.It is loaded down with trivial details that this legal system is made the erection procedure complicacy, the expense of taking a lot of work material, and also construction quality is low.On the other hand the washroom seepage be residential project big common quality defect, especially a through-flooring PVC-U pipeline and floor drain around more outstanding.Its main cause is that the workman produces seepage because of blocking up the hole leakiness in work progress, and the PVC-U pipe differs greatly with the concrete coefficient of expansion simultaneously, owing to expand with heat and contract with cold, seepage can occur after a period of time behind the PVC-U pipe plug hole, must draw attention to this.

Certain residence floor engineering of my unit; The washroom hole to be provided adopts this kind antiseep to exempt from stifled hole PVC service sleeve; This sleeve pipe directly is embedded in deck when concreting; Replaced the complicated procedures of forming in the stifled hole of traditional box out, fundamentally solved leakage in toilets, installed very convenient and swift simultaneously.

The utility model content

In order to solve the construction quality problem that the construction of toilet drainage pipeline through-flooring exists; The utility model provides a kind of antiseep to exempt from stifled hole PVC sleeve pipe; When concreting, directly be embedded in deck; Replaced the complicated procedures of forming in the stifled hole of traditional box out, fundamentally solved leakage in toilets, installed very convenient and swift simultaneously.

The technical scheme that the utility model adopted is:

Use service sleeve in a kind of bathroom floor concrete pouring construction, this service sleeve integral body is cylindrical structure, comprises pipe fitting, middle pipe fitting and following pipe fitting; Pipe fitting is provided with sealing wing ring on it; Middle pipe fitting is a bucket type variable section structure, and following pipe fitting is provided with fixed underpan, is evenly equipped with four fixing holes on the flanging of fixed underpan; Improvement is:

The external surface of said service sleeve is a rough surface, and the external surface of whole service sleeve is coated with circular thrust;

Be equipped with the interior slotting ring that stretches into down pipe fitting in the middle pipe fitting bucket type bottom of said service sleeve, form downward inner groove between interior slotting ring ring wall and the service sleeve tube wall;

Four fixing hole positions of said fixed underpan flanging are respectively equipped with protruding stiffening rib.

The useful technique effect of the utility model is:

1, the outer wall of integral built-in sleeve pipe is that rough surface (pitted skin) can increase sleeve pipe and concrete contact area, effectively blocks leak path;

2, the interior slotting ring 7 of pipe fitting 3 bucket type bottoms is inserted into (PVC-U pipe upper end is installed in the inner groove) in the PVC-U pipe in the service sleeve, even there are bonding defect in sleeve pipe and pvc pipe, and also can seepage;

3, the fixed underpan of band stiffening rib 5 makes the sleeve pipe fixation, installs simple.

Fig. 1 is the utility model structural representation.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the user mode figure of the utility model.

Fig. 4 is the outer facade expanded view of the utility model.

Among the figure: slotting rings, 8 concrete floors, 9PVC-U pipe, 10 circular thrusts in pipe fitting in pipe fitting, the 2 sealing wing rings, 3,4 fixed underpans, 5 stiffening ribs, 6 fixing holes, 7 on 1.

The specific embodiment

Embodiment:

Below in conjunction with accompanying drawing, the utility model is done explanation further through embodiment.

Details and effect that the construction and installation processes have been considered in the scientific design that antiseep is exempted from stifled hole PVC service sleeve can satisfy the requirement of antiseep, and its structure is referring to Fig. 1, Fig. 2 and Fig. 4.

Use service sleeve in a kind of bathroom floor concrete pouring construction, comprise pipe fitting 1, middle pipe fitting 3 and following pipe fitting; This service sleeve integral body is cylindrical structure, and the external surface of service sleeve is done roughened surface treatment, and through diameter 3mm, the circular thrust 10 of high 1mm (row, column pitch 3mm) covers whole outer surface and makes pitted skin, increases sleeve pipe and concrete contact area; Pipe fitting is provided with sealing wing ring 2 on it; Middle pipe fitting 3 is a bucket type variable section structure, and pipe fitting is provided with fixed underpan 4 under it, is evenly equipped with four fixing holes 6 (fixing with iron nail) on the flanging of fixed underpan 4; Four fixing hole 6 positions are respectively equipped with protruding stiffening rib 5.

Be equipped with the interior slotting ring 7 that stretches into down pipe fitting in the middle pipe fitting 3 bottom bucket types of service sleeve, form downward inner groove between interior slotting ring 7 ring walls and the service sleeve tube wall; When the PVC-U pipe was installed, the PVC-U of lower floor pipe upper end was installed in the inner groove, even there are bonding defect in sleeve pipe and pvc pipe, and also can seepage.

Antiseep is exempted from stifled hole PVC service sleeve pre-buried as shown in Figure 3 in concrete structure.Concrete operations are following:

1, the local mark signature line of service sleeve is installed at needs, is anchor point with the center.

2, service sleeve is made progress, be fixed on the concrete slab form to be poured with iron nail.

3, fill up the service sleeve that fixes with sand or be inserted in tubing above.

4, treat can install after project subject building is accomplished, PVC-U tubing directly and service sleeve connect with special PVC is gluing.

Antiseep is exempted from the PVC service sleeve construction of stifled hole only needs 1 people (general worker) to operate upstairs, easily installs.Working face is smooth bright and clean pollution-free, need not later stage cleaning cutter mill.Can improve work efficiency 6-8 doubly, save labour cost 90%.

Sleeve pipe combines closely with pipeline and floor, and sleeve pipe is direct and tubing is glued, need not filling-up hole between the levels, has stopped the infiltration hidden danger that causes thus, has improved construction quality.

This PVC service sleeve cost performance is high, can make all size size, and construction speed is fast, improves construction quality, for enterprise brings economic benefit and social benefit, increases the competitiveness of enterprise in the same industry.
