Abstract
The invention relates to a construction method 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 in senior middle school's low-voltage cable wall-through hole hole, particularly to a kind of be easy to cable increase-volume can
The construction method of dismountable fireproof blocking.
Background technology
Currently for cable fire-proof, it is distinctly claimed in State Grid's engineering cable design specification GB50217-2007：Cable
In structures cable be led to regulator cubicle, disk or control panel, the osseotomy site of platform, cable penetration partition wall, at the hole of floor,
In active well, cable pore all should implement fireproof blocking.Hole on wall is passed through and entering the cable of power distribution cabinet, Ying Shi
Apply fireproof blocking.Domestic at present commonly used method probably has 3 kinds.It is cable will to be had to wear with the common square brick mud that adds water first
Hole more is shut.This method does not have the effect of fireproof blocking, once there being the condition of a fire, the heat of flame can make wall crazing
Deformation, flue gas and heat can pass through body of wall, flame also can skewered to hole other side.Once cable to be increased it is necessary to
Break brick good body of wall, be very trouble, and cable may be injured.Second method is with preventing that rock wool or Gypsum Fibrosum are made
Fiery plate blocks hole.Because this material is met, fiery expansion rate is low, and flameproof effect is also bad, and not environmentally, harmful
(having carcinogen).Hole is shut by the third with fire prevention bag, because fire prevention bag is piled up, not bery fixing.Cable
Wriggling or vibrations fire prevention bag all can be made to fall down, thus losing fireproof effect.
Content of the invention
The technical problem to be solved is to overcome the deficiencies in the prior art, provides and a kind of is easy to the detachable of cable increase-volume
The construction method of formula fireproof blocking.Fire protecting performance is good, facilitate cable increase dilatation, and neatly, attractive in appearance.
For achieving the above object, the present invention employs the following technical solutions realization：
It is easy to the construction method of the detachable fireproof blocking of cable increase-volume, using beating expansion bolt on the wall of hole, make
With wing nut, expansion fire-proof plate is blocked on hole, and crammed at the gap of hole with organic fire prevention calking.Specifically
Step is as follows：
1. the cable that will be travelling through hole is placed on a side of hole, and will be travelling through being wound around one layer on the cable at fire prevention Board position
Back-fire relief band is simultaneously fixing；
2. be spaced on the wall apart from hole edge certain distance squeezes into expansion bolt, for larger-size hole, needs
Set up metal beam in hole centre position；
3., according to the size of cable and the position passing through PLASTIC LAMINATED, PLASTIC LAMINATED is cut out and passes through mouth-shaped accordingly；According to swollen
Swollen bolt is squeezed into position and is holed on PLASTIC LAMINATED；
4. with wing nut, PLASTIC LAMINATED is fixed on hole, and is crammed at the gap that PLASTIC LAMINATED is with wall with organic fire prevention filler
And at the gap that crosses of cable and PLASTIC LAMINATED；
5. during cable increase-volume, pull down wing nut and remove lower PLASTIC LAMINATED, in passing through of capacity-increasing cable, back-fire relief band is wound around on position,
The shape of the cable penetration mouth of increase-volume is cut out on PLASTIC LAMINATED, then again PLASTIC LAMINATED is reinstalled in the expansion bolt on wall
On, wing nut of screwing on, cable increase-volume mouth is crammed organic fire prevention calking.
A kind of detachable fireproof plugging structure being easy to cable increase-volume, including expansion fire-proof plate, expansion bolt, butterfly spiral shell
Female；Expansion bolt is arranged on the body of wall of cable penetration hole edge, and PLASTIC LAMINATED passes through the connection of wing nut and expansion bolt
On hole, fire shield edges are overlapped on body of wall, and PLASTIC LAMINATED is provided with cable penetration opening, pass through the electricity at opening for closure
Coat back-fire relief band outside cable, cable with wear PLASTIC LAMINATED and get at the gap of opening and at the gap of PLASTIC LAMINATED and body of wall filling organic anti-
Fiery putty.
A kind of detachable fireproof plugging structure being easy to cable increase-volume, also includes being arranged on the metal in the middle of cable penetration hole
Crossbeam, metal beam is processed two rows screwed hole, fixes 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：
The fireproof blocking of the present invention is detachable, is easy to cable increase-volume construction, it is to avoid the destruction to fireproof blocking during increase-volume, reduces
The waste of material, shortens the engineering time simultaneously.3M expansion fire-proof composite plate used in the present invention has meets what fire expanded
Feature, once there being the condition of a fire can live gap between cable and PLASTIC LAMINATED by Expansion sealing immediately, prevents spreading of flame and smog.
In addition PLASTIC LAMINATED also has the function of mouse bite preventing.There is visual effect clean and tidy, attractive in appearance simultaneously.
