Description

The assembly sleeve for piping < RTI ID = 0.0 >

More particularly, the present invention relates to a sleeve which is installed to prevent rusting of piping such as a steel pipe and an STS pipe during a building operation and a block installation of a building, thereby improving airtightness and watertightness, The present invention relates to a prefabricated sleeve for piping which can be easily disassembled and coupled by a one-touch assembly.

Generally, when a multi-layered building such as a building, an apartment, or a villa is desired to be constructed, it is subjected to various work such as ventilation pipes, gas pipes, cold / hot water pipes, sewage and sewage treatment pipes, In the process of installation, it is installed stably using a sleeve or the like buried in the concrete wall when the masonry and block are installed.

That is, prior to pouring concrete into each interlayer formwork, it is possible to construct an interlayer building with a plurality of diameter pipes installed through a sleeve installed at a predetermined position, and each of these pipes Ventilation, gas, cold / hot water, sewage and sewage.

As described above, the general piping is provided with a construction sleeve when it passes through the masonry and the block installation site, and when the cement is directly contacted with the piping such as the steel pipe and the STS pipe during the plastering operation, it is oxidized and rusted. .

However, since the joint and block work are generally performed after completion of the piping work, there is a problem that if the sleeve is not treated after completion of the piping work, the sleeve is inserted and reworked after cutting the piping to perform the sleeve work.

Accordingly, it is a first object of the present invention to overcome the above-mentioned problems and to solve the problem of reworking a sleeve to cut a pipe to perform a sleeve operation when the sleeve is not treated after piping work, The second is to provide a sleeve for piping which can prevent rusting of piping by improving airtightness and watertightness and is easy to disassemble and bond by one-touch assembly. .

In order to accomplish the above object, the present invention provides a piping sleeve used for stably fixing a piping penetrating through a building during a building operation and a block installation, the piping sleeve comprising: a hinge portion rotatably formed at the center; A coupling piece having a rectangular band shape and one side of which is longitudinally coupled to the distal end of the outer peripheral surface of the female coupling body and the other side of which is formed with a linear coupling groove in the longitudinal direction, And a coupling protrusion protruding from the distal end of the outer circumferential surface of the male coupling body and fitted in the coupling groove to be locked at a position corresponding to the coupling groove.

According to the structure of the present invention as described above, when the sleeve is not treated after completion of the piping work, it is possible to solve the problem of cutting the pipe to cut the pipe to rework the sleeve, thereby achieving economical efficiency Invention.

Also, by improving the airtightness and the watertightness, it is possible to prevent the pipe from rusting and it is a very useful invention which is easy to disassemble and combine by one-touch assembly.

FIG. 2 is a perspective view showing a coupling state of a pipe sleeve according to an embodiment of the present invention; FIG.
3 is a perspective view showing a coupling relationship of a pipe sleeve according to another embodiment of the present invention;

Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a disassembled state of a sleeve for piping according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a state of a sleeve for piping according to an embodiment of the present invention.

1 and 2, a sleeve for piping according to an embodiment of the present invention is a sleeve for piping which is used for stably fixing a piping which is inserted through a building operation and a block installation of a building, A female coupling body 200 and a male coupling body 300 each having a semicylindrical shape are formed on the left and right sides of the hinge portion 100 as a center of the hinge portion 100, 200, a coupling piece 400 formed in the longitudinal direction at the distal end of the outer peripheral surface of the male coupling body 300 and formed with a linear coupling groove 410 in the longitudinal direction, And a coupling protrusion 500 which is fitted in the coupling groove 410 and is locked as a position corresponding to the coupling groove 410.

The sleeve for piping according to the embodiment of the present invention is made of polyvinyl chloride resin and the hinge part 100 of the sleeve is composed of the left and right arm coupling body 200 and the male coupling body 300 So that the arm coupling body 200 and the male coupling body 300 can be pivoted up and down as an integral type.

Meanwhile, the pipe sleeve of the present invention is not limited to a PVC material or a PVC material, and all of the rigid polymers in a synthetic resin can be used.

Each of the female coupling member 200 and the male coupling member 300 has a semicylindrical shape and is positioned at the left and right sides of the hinge 100 and is folded up and down about the hingable portion 100 which is rotatable and closed Repeatable.
