Description

Auxiliary stopper for piping {A sub-stopper for a piping}

The present invention relates to an auxiliary stopper for plumbing so that mortar does not penetrate into the inside of a pipe when a construction (concrete work) constituting a wall is detached from a pipe of a pipe installed in various walls of a building. The structure is simple and the productivity is high, it is economical, the work is done quickly and accurately, and it improves the sealing property of a pipe, and it is related with the auxiliary plug for piping which can discharge the water used at the time of the water leakage inspection.

In general, various pipes including water pipes, gas pipes, and electric pipes are installed on the walls of various buildings, and when the walls are formed using concrete mortar, the pipes are buried in concrete to construct a wall. Done.

Accordingly, when the faucets, sockets, and valves connected to the pipes are connected to the outside of the wall after the building is completed, the pipes are exposed to the outside by destroying the wall of concrete constituting the wall. After installation, repair the destroyed wall.

Therefore, conventionally, to complete the construction of the building after wiring and plumbing work, it is inevitable to drill the walls one by one, to perform the plumbing and wiring work, and to close the hole again after the work, which takes a lot of work time and requires additional wiring or plumbing work. There was a problem of rising expenses.

Accordingly, in recent years, it has been proposed to solve the above-mentioned conventional problems, that is, the problem of having to perform construction by destroying the wall, and as shown in FIG. Pipes, L-tubes, etc.) and then install an auxiliary stopper to open and close the exposed hole of the connecting pipe, and during construction work, close the exposure hole with a stopper and perform the construction, and after the wall construction is completed, After the stopper is removed from the exposure hole, it is proposed that the necessary device (faucet, socket, valve, etc.) to be fastened, the situation is widely used.

The auxiliary plug as described above typically has a threaded portion 4 screwed into the exposed hole of the connector 2 as shown in FIG. 1 and a body 5 for opening and closing the exposed hole of the connector 2. Consists of.

The screw portion 2 is provided with a packing for improving the closing performance.

In the above, the length of the body 5 has a length sufficient to be exposed to the outside of the wall.

Therefore, when constructing the wall, install the pipe (1) and the connection pipe (2) into the interior of the wall, and then attach the auxiliary plug to the exposed hole of the connection pipe (2) and perform the concrete work pipe (1) and connection The pipe 2 is embedded into the wall and only the auxiliary plug is exposed to the outside of the wall to form a wall.

When the construction of the wall is completed, the auxiliary plug is separated from the connecting pipe 2, and then the work is completed by combining the faucet, socket, valve, etc. required for the exposed hole where the auxiliary plug was screwed.

Therefore, when constructing the wall, the work can be performed without breaking the wall.

However, the conventional auxiliary pipe stopper as described above is provided with a separate packing on the screw portion to have a sealing property with the connection pipe, so that not only the body but also a separate packing suitable for the body, the productivity is uneconomical and disadvantageous There was this.

In addition, since the work to be posted on the packing is performed when the coupling pipe and the auxiliary plug is performed, there is a problem that the working time is long and the progress of the work is inconvenient.

After the construction of the wall is completed, after performing the hydraulic test to test the air tightness of the pipe, when the water pressure (water) is removed, the drainage is made only through the inlet of the water, so it is difficult to discharge the water smoothly and complete drainage is not possible. There was a problem.

In addition, there was a problem that can not determine whether the water is properly injected because the inside of the pipe can not be visually checked during the hydraulic pressure test, it is not possible to secure the reliability of the inspection work.

The present invention has been proposed in order to solve the above-mentioned conventional problems, the object of the present invention is that the structure is simple, high productivity and economical, work is done quickly and accurately, as well as improve the sealability of the pipe, It is an object of the present invention to provide an auxiliary cap for plumbing, which can discharge water used in water leakage inspection, and in particular, can see through the inside of the pipe to ensure the reliability of the hydraulic pressure inspection.

The auxiliary pipe stopper of the present invention for achieving the object of the present invention as described above in the pipe auxiliary stopper that is detachable to open and close the connection pipe of the pipe installed in the interior of the wall, exposed from the outside and the inner surface It is made of a body having a screw portion is screwed to the tube formed in the nut acid in the screw portion is characterized in that the coating layer made of a synthetic resin material having elasticity is integrally formed through a double injection method.

In addition, the auxiliary stopper for the pipe of the present invention for achieving the object of the present invention as described above is provided with a distribution groove in which the hydraulic pressure is communicated in communication with the pipe hole of the connecting pipe inside the body, at the top end of the distribution groove Characterized in that a perforated groove is formed to easily perforate.

And the auxiliary stopper for the pipe of the present invention for achieving the object of the present invention as described above is provided with a distribution groove in which the hydraulic pressure is communicated in communication with the pipe hole of the connecting pipe inside the body, Both sides are characterized in that the fracture groove is formed to facilitate the separation of the best end of the body by breaking.

In addition, the auxiliary stopper for the pipe of the present invention for achieving the object of the present invention as described above is provided with a distribution groove in which the water pressure is communicated in communication with the pipe hole of the connecting pipe inside the body, the top end of the body Characterized in that the cover is screwed with the packing

And the auxiliary stopper for the pipe of the present invention for achieving the object of the present invention as described above is provided with a distribution groove in which the hydraulic pressure is communicated in communication with the pipe hole of the connecting pipe inside the body, the best end of the body It is characterized by being able to see the inside of the distribution groove with the naked eye.

In addition, the auxiliary stopper for the pipe of the present invention for achieving the object of the present invention as described above is provided with a distribution groove in which the water pressure is communicated in communication with the pipe hole of the connecting pipe inside the body, the top end of the body It is characterized in that the see-through member is fusion-bonded to visually see the inside of the distribution groove.

Since the auxiliary plug for the pipe of the present invention made as described above does not have to have a separate packing when combined with the connecting pipe, its structure is simple, the productivity is high, economical, and the work is made quickly and accurately, In particular, if the distribution groove is exposed to the outside, the water used for water leakage inspection by water pressure can be smoothly discharged, and the hydraulic inspection can be performed while visually checking the inside of the distribution groove. It has the effect of ensuring reliability.
