The present invention relates to a protective tube (electric line, telephone line, communication line, etc.) buried in the inner wall of a general building or apartment house, and more specifically, it can be stored separately divided into various types of wires inside the state It is easy to extend the work, and the drawing of the electric wire is easier in the interior work, and the unused openings close the door to prevent the leakage of noise, and more rigidly embedded in the wall wire protection tube for building will be.

Due to the increase in population, residential space is relatively reduced, and apartments, which are apartment houses, are increasing, and these apartments have all the facilities in the interior, and are very convenient to use, thus becoming a form of housing that most people want to live in.

Conventional apartments only need to be wired with electric cables, but in recent years, the use of various medicinal wires other than electric cables, such as telephone lines, high-speed Internet lines, and CATV / MATV cables, is needed to construct apartments with diversified and high-speed media. For this purpose, a communication EPS room or a PIT is provided for each floor and wired using a cable tray.

However, since the communication EPS room or the PIT has a very large area of about 1.3 × 0.7 (㎡), this causes a decrease in the common area, resulting in a narrowing of the actual living space. It is difficult, and unnecessary construction costs have increased, and it is difficult and expensive to construct piping from the telephone generation terminal box to the EPS room, and there are many problems of defects because the floor pipe passes through the toilet floor.

In addition, when installing without installing a communication EPS room or a PIT, a large amount of PVC conduits accommodating various electric wires are purchased in a frame. In this case, conduit construction is very difficult and structural strength is weak. Reinforcement of reinforcement is required, there is a risk of being damaged by anchor or drill after winning the line, and when it is damaged, repair is almost impossible and material and labor costs are high.

In order to solve this problem, an opening is formed at one side of the lower side of the duct having a four-sided pipe shape so as to expose an inner space in the front direction, and a protrusion having joint holes is formed at both sides thereof, and at one side of the upper side, the wall of the duct is embedded. The support piece is attached in the same direction as the protrusion so as to support the position, and at the upper end, the outer edge forms the frame contraction part like the inner edge of the other part so as to connect another duct in the vertical direction. It is installed vertically so as to be buried in one wall so that the inner space of the duct can be communicated through the entire building, and the protrusion is positioned to be exposed to the outside of the wall, and the inner space of the duct integrates a telephone line, a communication line, and a TV cable, which are weak electric lines. The protection duct for the integrated wire embedded in the wall, characterized in that receiving 2003 On March 18, it was registered and registered as Utility Model Registration No. 20-262291.

However, such a conventional integrated duct protection duct has a telephone line, a communication line, a TV cable integrated to accommodate, but can not be stored separately by its type, there is an uncomfortable problem in extension work, the opening is formed in only one place, the wire during the interior work There was a problem in that the withdrawal is inconvenient and the appearance is not beautiful.

The present invention is to solve the above problems, it is possible to separate and store the various types of wires in the state classified by their type, so that the extension work is easy, the drawing of the wires during the interior work is easier, and use The opening that does not have the purpose of closing the door to prevent the leakage of noise, and more rigidly embedded in the wall to provide a building inner wall wire protection tube that is fixed and supported.

In order to achieve the above object, the present invention is a flat octagonal pillar, the inner surface of the inner surface is formed in the upper and lower support recesses, the engaging recess is formed in the left and right in the support recess, the inner groove is formed in the left and right outer periphery Anchor bolts are formed at the upper and lower portions of the insertion grooves, and insertion rings are formed at the left and right outer peripheries, and wire inlet holes are formed at the upper and lower sides thereof. A fastening recess into which a bar is inserted is formed, and a protective tube body having an opening inwardly formed at the lower side of the front side;

One end is formed with a protrusion to be inserted into the insertion groove of the protective tube body, the upper and lower portions are formed with a wing portion having a fastening hole for fastening and fastening the anchor bolt is fastened by a fastening nut, the other end is a ring inserted and fixed by elasticity in the back muscle An additionally formed dorsal root fixture;

The front and rear open box shape is inserted into the opening of the protective tube body, and the wire through holes are formed on the upper and lower sides of the wire inlet hole extension line, respectively, the fitting bolts are formed at the left and right ends, and the front protrusions have the fitting protrusions protruding to the front side. A terminal box having one side of the fitting bolt penetrated thereto and having a bolt hole fastened and fixed by a nut, and the other end extending to have a fitting bar inserted into the insertion ring;

The elastic body is characterized in that it has a stopper plate having a fitting recess in which the fitting protrusion in front of the terminal box is fixed.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
