Description

FIELD OF THE INVENTION [0001] The present invention relates to a control cable terminal processing apparatus for an explosion-

More particularly, the present invention relates to a control cable terminal processing apparatus for a fire fighting compartment which is capable of cost reduction, is easy to install, and has excellent fire resistance and durability.

Fireproofing materials are materials that prevent or prevent the spread of fire by applying or winding materials with fire resistance to the floor sleeve or wall wires of the building or sealing the penetration of wires and control cable trays.

Of these, the control cable anti-flammability agent shall be a product that has undergone the certification test of an authorized testing institution (test according to KSF 2257, FS 012) that can meet the 2-hour fire resistance T rating requirement in the state of penetration control cable. Or more.

There are two types of control cable combustion inhibitor: foamable and non-foamable. In general, anti-fusing tapes, anti-fog paints, anti-burning putty, silicone silicone foam (Silicone RTV foam) are used.

Currently, the fire protection partition re-construction standard is to fill the openings with Silicone RTV foam.

As shown in Fig. 1, a margin 9 connected to the cable duct 5 is provided on the concrete floor 7, and an electric switchboard 11 for protecting and withdrawing the control cable 1 is installed on the concrete floor 7, , The fire partitioning material (20) is installed in the opening (13) of the switchboard (11).

The fire partitioning material 20 is composed of a fireproof pad 21 and a fireproof silicone 23.

2, after the edge is reinforced by the ALC block 25, the remaining space between the control cables 1 is sealed with the fireproof pad 21, (23), but has a weak durability and a difficulty in complete sealing.

ALC (Lightweight Foam Concrete) block is certified for fire spreading of the contact part between Silicone RTV foam and ALC block (25) Is used as a sealing material for the opening 13 of the sealing member 11.

Also, the fire partitioning material shown in Fig. 1 is difficult to dismantle and can not be reused, which is not permanent. Particularly, fireproof silicon and fireproof pad are expensive, so the construction cost is high and the control cable is required to be reworked.

Particularly, in the case of a large opening, there is a problem that an excessive amount of fire silicone is required and installation is difficult.

Alternatively, the perimeter of the control cable can be filled with fireproof silicone and the rest sealed with a refractory board. However, in this case, the 2-hour refractory T grade could not be guaranteed and was judged to be nonconformity.

As another alternative, the galvanized steel sheet can seal the opening of the switchboard. However, in this case, in order to prevent the fire from spreading to other parts, the heat generated by the combustion must maintain a temperature below the ignition point which may cause combustion in other parts. However, the thermal conductivity of the galvanized steel sheet (45 kcal / It did not satisfy fire resistance T grade.

The object of the present invention is to provide a control cable terminal processing apparatus for a fire fighting compartment which is capable of cost reduction without using expensive materials, is detachable, and has excellent nonflammability and durability.

According to a first aspect of the present invention, there is provided a control apparatus for a control cable, comprising: a terminal processing membrane which is installed to enclose an opening formed in an electric distribution board and has a wire drawing-out port for drawing a wire of a control cable drawn out to the opening, And a sealing means for sealing the wire drawing port from which the wire of the cable is drawn out.

The lower portion of the terminal processing membrane can be fixed to the switchboard with an attachment metal and a screw.

The terminal treatment membrane may be a carbon fiber cloth composite aluminum foil cloth.

A ground line outflow opening may be formed in the terminal processing film.

The sealing means may include a fireproof filler filled in a gap between the element wire and the wire drawing-out port, and a banding member wrapping and fixing the outer circumferential surface of the wire drawing-out port filled with the fireproofing agent.

The fire retardant filler may be fireproof silicone and the bending member may be a threaded band.

The terminal treatment film has a double structure formed by superposing two sheets, and a flame retardant cotton can be filled between the double structure.

The terminal processing membrane may be a box made of a hard flame retardant plastic material.

The sealing means may include a nonflammable nonwoven fabric filled in a gap between the wire and the wire drawing port, and a nonflammable tape wrapping and fixing the wire drawing port filled with the nonflammable nonwoven fabric.

The sealing means may include a silicone silicone (Silicone RTV foam) filled in a gap between the wire and the wire drawing port.

This design makes it possible to use the terminal treatment film (high strength carbon fiber cloth composite aluminum foil cloth) to the opening part of the switchboard, so that it can be used in a wide area and has high durability.

In addition, the present invention has the effect that the lower portion of the terminal processing membrane is firmly attached and sealed by the mounting bracket and the screw type screw, so that the terminal can be easily detached and reused, and can be used semi-permanently.

In addition, the present invention can completely seal the control cable by drawing the control cable to the single wire single wire outgoing opening and sealing the single wire outgoing opening of the single wire by the sealing means, so that the internal pressure from the flame is high.

In addition, this design has the effect of drastically reducing the construction cost because expensive silicon fireproofing is not used or is used only for a part when used.

In addition, the present invention can include a nonflammable nonwoven fabric, a flame-retarding cotton, etc. in the heat-treated film, and the effect of heat insulation can be enhanced by using the thickness of the heat-treated film and the thickness of the flame retardant cotton flexibly.
