Abstract

A protection case structure for electric and communication cables in a public building is provided to facilitate a wiring process by freely defining wiring spaces in the protection case structure. A protection case structure for electric and communication cables in a public building includes a base body(10), an extraction outer tube(20), a spacer, an extraction inner tube(40), a sealing tube(50), and a coupling fixing hook(60). Plural cable spaces are formed inside the base body. Cable tubes, through which cables penetrate, are formed inside the cable space. Through-holes are formed at left/right portions of upper and lower front surfaces of the case body. The extraction outer tube is fixed on upper and lower cable extraction holes of the case body and includes wing portions, which are formed on upper and lower portions of a rear surface thereof. The spacer includes a ring portion having a coupling hole, to which an anchor bolt of the extraction outer tube is inserted. Support bars, which support both ends of the cable tube of the case body, are formed on the spacer. The extraction inner tube is fixed on the ring portion of the spacer. A front portion of the extraction inner tube is enclosed by a cover. The sealing tube is coupled with an anchor bolt elongation line of the cable extraction hole of the case body by a nut.

The present invention relates to an electrical and communication cable protective case structure, more specifically, the construction is easy without the narrowing of the residential space, less likely to cause defects, made of a prefabricated structure, easy distribution management, free wiring space As it can be divided, wiring work is made more efficiently, and connection structure with reinforcement can be achieved, and it is related to the structure of the housing case for electric and communication cable protection in the housing complex that can maintain a solid installation state.

Due to the increase in population, residential space has been relatively reduced, leading to the increase of apartments, which are apartments. These apartments have all the facilities indoors and are very convenient to use, making it 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 except electric cables such as telephone lines, high-speed Internet lines, CATV / MATV cables, etc. In order to achieve this, a communication EPS chamber 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. Difficult, unnecessary construction costs increased, plumbing construction was difficult and expensive, from the telephone generation terminal box to the EPS room, there was a lot of 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. Separate reinforcement is required, there is a risk of being damaged by anchors or drills after winning the line, repair is almost impossible at the time of breakage, and material and labor costs are high.

The present invention is to solve the above problems, the construction space is not narrow, easy construction, less occurrence of defects, it is made of a prefabricated structure, easy distribution management, can be freely divided wiring space The wiring work is more efficient, and the connection with the reinforcement can be achieved to provide a housing case electrical and communication cable protection casing structure that can maintain a steady installation state.

In order to achieve the above object, the present invention is an upright rectangular tube body, a plurality of cable spaces are formed by the partition plate inside the plane, a cable pipe is formed inside the cable space through the cable space, Fastening bar protrudes upward on the upper left and right sides, and fastening grooves are formed at the lower left and right sides, and fastening bars are inserted in the lower left and right ends. Cable take-out hole protruding a plurality of anchor bolts is formed in the periphery, the case body formed with a through hole in the upper and lower left and right sides;

The upper and lower cable drawing hole of the case body is fastened and fixed, the upper and lower end of the bolt is inserted into the anchor bolt is formed by the nut is fastened and fixed by a nut, the anchor bolt protrudes from the front upper and lower ends Appearance;

A spacer having a ring portion having a fastening hole into which the anchor bolt of the drawout tube is inserted, protruding from the upper and lower portions at the rear of the ring portion to the rear, and supporting bars for supporting the cable tube of the case body at both sides through the drawout;

A drawing inner tube inserted into and fixed to a ring portion of the spacer, and a front body sealed by a cover;
