Description

[0001] The present invention relates to a multi-part fire-resistant fire-resisting device for a penetrating part which is easy to install and maintain,

More particularly, the present invention relates to a multi-split fire-fighting apparatus for a penetrating portion which is easy to install and maintain, and more particularly, To a fire-extinguishing device.

Electricity generated in the power plant is transmitted and distributed through the power grid and connected to the customer. If a fire occurs at a certain point due to cable deterioration or other causes, the fire can continue along the cable. To prevent such a fire, firewalls are formed at intervals of about 200 m between the substation and the power sphere and the power sphere . In the center of the firewall, a penetration portion through which a cable is inserted can be formed, and it is necessary to install a facility that can effectively block the progress of a fire.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing a fire-resistant filler for a fire partition penetrating portion of a conventional building.

In order to compress the incombustible material or the fire by using the vacuum equipment, the vacuum packaging paper 20 may be sealed with a non-combustible material or a fireproof material, or may be sealed in the form of wrapping the material, or a hole may be formed, It is. Here, the vacuum pouch is one of an aluminum coating film, a Veppa barrier, and a plastic film. The Vefa barrier is a film containing a refractory seal in an aluminum coating film.

However, the conventional refractory filler has a number of problems. Generally, the conventional refractory filler for the fire partition penetrating portion is filled with a foaming material to finish the fireproof filler. When the refractory filler is in foam form, the installation process is complicated and complex, from material identification, mixing equipment identification, mixing, Silicon RTV foam construction and removal, to the final confirmation of the construction and density of the foam, If you are not an engineer, you will have a lot of difficulties in compounding and installing the data. In addition, it takes a long time to complete the construction in the form of a liquid in the field, and the damage due to the impact such as the vibration due to the generation of the pore due to the load of the cable at the time of aging and poor construction and the fault current, And there is a problem that it is not possible to reuse the cable when the installation or replacement of the cable is required after the site construction.

In addition, there is a problem that it is difficult to horizontally penetrate through the center of the penetrating portion due to the load of the electric wire, so that the cable is eccentrically installed in the gravitational direction and it is difficult to maintain the fire performance properly.

Meanwhile, in the case of the refractory filler using the vacuum pavement as shown in FIG. 1, the vacuum is released and the volume expands, so that it is not easy to fill the clearance of the penetrating portion effectively, and an excessive amount of the refractory filler is supplied. In addition, there is a problem that re-use is not possible as in the case where the refractory filler is in the form of a foam, and a new facility must be newly installed at the time of cable installation or replacement.
