Abstract

The utility model discloses a pre-buried pipe fitting of PPR pipe, including outer body and interior body, interior body is worn to establish outer body center, outer body one end with be provided with two folding connecting blocks between the interior body outer wall, outer body periphery is provided with a plurality of holding rings, separate into the concrete holding tank through the protruding muscle of a plurality of axial between the holding ring. This kind of pre-buried pipe fitting of PPR pipe is pre-buried when concreting in the floor, be connected through two folding connecting blocks between outer body and the interior body, thereby make and to bear certain deformation between the interior outer pipe, offset the stress that water pipe or concrete expend with heat and contract with cold and produce, outer body periphery is provided with the holding ring, and separate into the concrete holding tank through a plurality of axial protruding muscle between the holding ring, the concrete enters into the concrete holding tank when concreting, both can prevent that the pipeline is not hard up, also can prevent the seepage of gap normal water.

Description

Pre-buried pipe fitting of PPR pipe

Technical Field

The utility model belongs to the technical field of the PPR pipe, specifically a pre-buried pipe fitting of PPR pipe.

Background

When the water pipe of floor is passed in the installation, generally be through the mode that directly punches, punch through the floor, then adorn the pipeline, it is fixed through grout all around with the pipeline again, adopt this kind of mode pipeline to become flexible easily around the use of pipeline, can appear the gap between pipeline and concrete, the seepage of water appears easily in the peripheral gap of pipeline in the use, and the thermal expansion shrinkage because of pipeline or the peripheral concrete of pipeline leads to the too big crack of appearance of body local stress easily.

Disclosure of Invention

The utility model is not enough to prior art, the utility model provides a pre-buried pipe fitting of PPR pipe, pre-buried income floor of this kind of pre-buried pipe fitting of PPR pipe when concreting, pre-buried pipe fitting includes double-deck body, be connected through two folding connecting blocks between outer body and the interior body, thereby make and to bear certain deformation between the interior outer pipe, offset the stress that water pipe or concrete expend with heat and contract with cold and produce, outer body periphery is provided with the holding ring, and separate into the concrete holding tank through the protruding muscle of a plurality of axial between the holding ring, the concrete enters into in the concrete holding tank when concreting, both can prevent that the pipeline is not hard up, also can prevent the seepage of gap normal water.

In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the utility model provides a pre-buried pipe fitting of PPR pipe, includes outer body and interior body, interior body is worn to establish outer body center, outer body one end with be provided with two folding connecting blocks between the interior body outer wall, outer body periphery is provided with a plurality of holding rings, separate into the concrete holding tank through a plurality of axial protruding muscle between the holding ring. This kind of pre-buried pipe fitting of PPR pipe is pre-buried when concreting in the floor, be connected through two folding connecting blocks between outer body and the interior body, thereby make and to bear certain deformation between the interior outer pipe, offset the stress that water pipe or concrete expend with heat and contract with cold and produce, outer body periphery is provided with the holding ring, and separate into the concrete holding tank through a plurality of axial protruding muscle between the holding ring, the concrete enters into the concrete holding tank when concreting, both can prevent that the pipeline is not hard up, also can prevent the seepage of gap normal water.

In the above technical solution, preferably, the outer tube body is provided with a corrugated elastic tube section, and the positioning rings are arranged on two sides of the corrugated elastic tube section. By adopting the structure, the outer pipe body can bear certain axial strain force to offset the stress generated by expansion with heat and contraction with cold of the water pipe or the concrete.

In the above technical solution, preferably, the pipe pre-buried pipe further includes plugs plugged at two ends of the outer pipe body and/or the inner pipe body. Adopt this structure to plug up the opening of interior body and outer body when pre-buried, prevent that the concrete from entering into interior body and outer pipe are internal.

Compared with the prior art, the utility model, following beneficial effect has: this kind of pre-buried pipe fitting of PPR pipe is pre-buried when concreting in the floor, be connected through two folding connecting blocks between outer body and the interior body, thereby make and to bear certain deformation between the interior outer pipe, offset the stress that water pipe or concrete expend with heat and contract with cold and produce, outer body periphery is provided with the holding ring, and separate into the concrete holding tank through protruding muscle between the holding ring, the concrete enters into the concrete holding tank when concreting, both can prevent that the pipeline is not hard up, also can prevent the seepage of gap normal water.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1-2, a pre-buried pipe fitting of PPR pipe, wholly form by PPR material moulding plastics, including outer body 1 and interior body 2, interior body 2 wears to establish at outer body 1 center, be provided with two folding connecting blocks 3 between outer body 1 one end and the interior body 2 outer wall, two folding connecting blocks 3 have twice the buckling in outer body 1 top, be connected to interior body 2 after buckling on, be provided with corrugate elastic tube section 7 on the outer body 1, corrugate elastic tube section 7 both sides all are provided with holding ring 4, separate into concrete holding tank 6 through eight axial protruding muscle 5 of evenly distributed between the holding ring 4.

This kind of pre-buried pipe fitting of PPR pipe is in pre-buried income floor when concreting, be connected through two folding connecting blocks 3 between outer body 1 and the interior body 2, thereby make and to bear certain deformation between the interior outer tube, offset the stress that water pipe or concrete expend with heat and contract with cold produced, 1 periphery of outer body is provided with the holding ring, and separate into the concrete holding tank through protruding muscle 5 between the holding ring, the concrete enters into the concrete holding tank when concreting, both can prevent that the pipeline is not hard up, also can prevent the seepage of water in the gap, certain axial strain can be born to corrugate elasticity pipeline section 7, offset the stress that water pipe or concrete expend with heat and contract with cold produced.

The two ends of the pipe embedded pipe fitting are blocked on the outer pipe body 1 and the inner pipe body 2 through the plugs 8, and concrete is prevented from entering the outer pipe body 1 and the inner pipe body 2 during pouring.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
