Abstract
The invention relates to a construction method and a structure of a detachable fire plug convenient for increasing the capacity of a cable. According to the method, expansion bolts are nailed on a wall provided with holes; expansion fire-proof composite plates are used for plugging the holes; a penetration hole is formed in a cable penetrating part; butterfly nuts which are convenient to detach are screwed on the expansion bolts to fix the fire-proof plates on walls around the holes; non-solidification fire-proof cement is used for sealing an aperture between the cable and each fire-proof plate and an aperture between each fire-proof plate and each wall. During increasing of the capacity of the cable, a capacity increasing hole is formed by detaching the fire-proof plates, and the fire-proof plates are arranged and sealed once again. The fire plug is detachable, so that the capacity-increasing construction of the cable can be performed conveniently; the used 3M expansion fire-proof composite plates have the characteristics of expanding in case of fire, and expand for sealing the gap between the cable and the fire-proof plates once fire occurs, so that the spreading of flame and smog is prevented. Moreover, the fire-proof plates have the functions of preventing rat biting, and have the effects of tidiness and attractiveness.
Description
Technical field
The present invention relates to the fireproof blocking construction of high, normal, basic voltage cable hole through walls, particularly a kind of construction method and structure being convenient to the detachable fireproof blocking of cable increase-volume.
Background technology
At present, for cable fire-proof, have in State Grid engineering cable design specifications GB50217-2007 and explicitly call for: in cable structure, cable leading is sent a telegraph cable pore in gas holder, dish or control flow, the perforate position of platform, cable penetration partition wall, the hole place of floor, active well and all should be implemented fireproof blocking.Entering the cable of power distribution cabinet for passing through from hole on wall, should fireproof blocking be implemented.The domestic method generally adopted probably has 3 kinds at present.First be add cement with common square brick to shut there being the hole of cable penetration.This method does not have the effect of fireproof blocking, once there be the condition of a fire, the heat of flame can make that wall crazing is out of shape, flue gas and heat can pass body of wall, flame also can skewered to the other side of hole.Once will cable be increased, just need to break brick good body of wall, be very trouble, and may cable be injured.Second method is the PLASTIC LAMINATED shutoff hole made with rock wool or gypsum.Due to this material, to meet fiery expansion rate low, and flameproof effect is also bad, and not environmentally, harmful (having carcinogenic substance).Hole is shut with fire prevention bag by the third, because fire prevention bag is piled up, not bery fixing.Wriggling or the vibrations of cable all can make fire prevention bag fall down, thus lose fireproof effect.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, provides a kind of construction method being convenient to the detachable fireproof blocking of cable increase-volume.Fireproof performance is good, facilitate cable increase dilatation, and neatly, attractive in appearance.
For achieving the above object, the present invention realizes by the following technical solutions:
Be convenient to the construction method of the detachable fireproof blocking of cable increase-volume, adopt and beat expansion bolt on the wall of hole, use wing nut by the shutoff of expansion fire-proof plate on hole, and cram the gap place at hole with organic fire prevention calking.Concrete steps are as follows:
1. the cable passing through hole is placed on a side of hole, and the cable at penetrate firewall Board position place will be wound around one deck back-fire relief band and fix;
2. on the wall of distance hole edge certain distance interval squeeze into expansion bolt, for larger-size hole, need in hole centre position erection metal beam;
3., according to size and the position of the cable of penetrate firewall plate, PLASTIC LAMINATED is cut out and passes through mouth-shaped accordingly; Squeeze into position according to expansion bolt to hole in PLASTIC LAMINATED;
4. with wing nut, PLASTIC LAMINATED is fixed on hole, and crams the gap place of PLASTIC LAMINATED and wall and the gap place that crosses of cable and PLASTIC LAMINATED with organic fire prevention filler;
5. during cable increase-volume, pull down wing nut and go lower PLASTIC LAMINATED, back-fire relief band is wound around passing through on position of capacity-increasing cable, PLASTIC LAMINATED cuts out the shape of the cable penetration mouth of increase-volume, and then on expansion bolt PLASTIC LAMINATED being reinstalled on wall, to screw on wing nut, cable increase-volume mouth is crammed organic fire prevention calking.
Be convenient to a detachable fireproof plugging structure for cable increase-volume, comprise expansion fire-proof plate, expansion bolt, wing nut; Expansion bolt is arranged on the body of wall of cable penetration hole edge, PLASTIC LAMINATED by the connection shutoff of wing nut and expansion bolt on hole, fire shield edges is overlapped on body of wall, PLASTIC LAMINATED is provided with cable penetration opening, coated back-fire relief band outside the cable passing through opening part, cable fills organic fire prevention calking with the gap place of wearing gap place and PLASTIC LAMINATED and body of wall that PLASTIC LAMINATED gets over opening.
Be convenient to a detachable fireproof plugging structure for cable increase-volume, also comprise the metal beam be arranged in the middle of cable penetration hole, metal beam is processed two rows screwed hole, fix PLASTIC LAMINATED for wing bolt.
Described expansion fire-proof plate is 3M expansion fire-proof composite plate.
Described organic fire prevention calking is 3M non-condensable type fire-proof mud.
Described back-fire relief band is 3M back-fire relief band.
Compared with prior art, the invention has the beneficial effects as follows:
Fireproof blocking of the present invention is detachable, is convenient to cable increase-volume construction, and the destruction to fireproof blocking when avoiding increase-volume, reduces the waste of material, shorten the engineering time simultaneously.3M expansion fire-proof composite plate used in the present invention has the advantages that to meet fire and expand, once there be the condition of a fire can live the gap between cable and PLASTIC LAMINATED by Expansion sealing immediately, prevents spreading of flame and smog.PLASTIC LAMINATED also has the function of mouse bite preventing in addition.There is visual effect clean and tidy, attractive in appearance simultaneously.
