Abstract
The utility model relates to a kind of cable-flame retardant plugging structure, comprise cable (1), fireprotection layer (2), back-fire relief bag (3), fire prevention calking (4) and body of wall (5), described fireprotection layer (2) is wrapped in the outside of cable (1), described back-fire relief bag (3) and fire prevention calking (4) are filled in the hole that formed between fireprotection layer (2) and body of wall (4), described fire prevention calking (4) is covered on back-fire relief bag (3), between back-fire relief bag (3) and fireprotection layer (2).The utility model can effectively be used in cable penetration place, plays good fire-block stem effect, has the advantages such as structure is simple, cost is low, easy construction, wide market.
Description
Technical field
The utility model belongs to fireproofing technique field, especially relates to a kind of cable-flame retardant plugging structure.
Background technology
Along with the develop rapidly of Chinese national economy and the increasing of modernization construction dynamics, the production of electric energy and use amount are increasing considerably, and the use of electric wire, cable is also more and more extensive.In laying wire, cable process, the cable that fire-resisting partition and floor are usually laid, pipeline run through, thus form corresponding cavity and gap.Fireproof plugging structure is exactly the hole that these exist potential safety hazard for shutoff, and when to avoid fire, the intensity of a fire is spread to the adjacent region of fire origin by hole, reaches the object of protection personal security.
Back-fire relief bag is because of easy accessibility behind good flame retardation effect, fire prevention good anti-moisture ability, shutoff encapsulating plug-hole hole, not containing the advantages such as Toxic composition such as asbestos, be effectively used to the cable penetration hole places such as power plant, industrial and mining enterprises, highrise building, petrochemical industry, mineral wool shutoff.But existing back-fire relief bag, because of surfacing, makes to pile up inconvenience, and easily form gap between building hole, and pile up and easily to cave in afterwards, thus the flameproof effect causing fire-retardant plugging structure to play is very limited.Be necessary to provide a kind of cable-flame retardant plugging structure for this reason, fire-retardant shutoff can be carried out in all directions, there is good flame retardant effect.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, a kind of cable-flame retardant plugging structure is provided, under the existence of cable fire-proof layer, by the back-fire relief bag of rule and fire prevention calking with the use of, hermetic plugging structure can be formed, reached good flame retardant effect.
For achieving the above object, the technical scheme taked of the utility model is as follows:
A kind of cable-flame retardant plugging structure, it is characterized in that, described cable-flame retardant plugging structure comprises cable (1), fireprotection layer (2), back-fire relief bag (3), fire prevention calking (4) and body of wall (5), described fireprotection layer (2) is wrapped in the outside of cable (1), described back-fire relief bag (3) and fire prevention calking (4) are filled in the hole that formed between fireprotection layer (2) and body of wall (4), described fire prevention calking (4) is covered on back-fire relief bag (3), between back-fire relief bag (3) and fireprotection layer (2).
Described fireprotection layer (2) is fireproof paint.
Described back-fire relief bag (3) is intumescent back-fire relief bag.
Described fire prevention calking (4) is flexible organic putty.
The beneficial effects of the utility model are as follows:
1, fireprotection layer (2) will foaming and intumescing when cable heat, can form the carbonization isolation layer of even compact, thus cable be played to the effect of fire-proof and thermal-insulation.
2, back-fire relief bag (3) at high temperature there will be expansion and solidification phenomenon, thus forms a kind of effective sealing, stops spreading of the intensity of a fire, and can not produce toxic and harmful containing toxic substances such as asbestos.
3, fire prevention calking (4) plasticity is high, with back-fire relief bag (3) with the use of, fully can tamp hole, ensure the plugging effect of good hole.
Accompanying drawing illustrates:
Fig. 1: the generalized section of a kind of cable-flame retardant plugging structure in the utility model.
detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1
As shown in Figure 1, a kind of cable-flame retardant plugging structure, comprise cable (1), fireprotection layer (2), back-fire relief bag (3), fire prevention calking (4) and body of wall (5), described fireprotection layer (2) is fireproof paint layer, be wrapped in the outside of cable (1), play basic fire retardation, having wrapped up in the hole formed between the cable (1) of fireprotection layer (2) and body of wall (4), first closely, entirely put back-fire relief bag (3), the organic putty of remaining space filling flexible (4), according to residue hole and gap, organic for flexibility putty (4) is rubbed, pinch shaping, tamp hole and extrude and enrich, form the plugging structure of good sealing.
Below only the utility model and embodiment thereof are described; this description is not restricted; shown in accompanying drawing is also one of embodiment of the present utility model; actual structure is not limited thereto; if those skilled in the art enlighten by it; when not departing from the utility model and creating aim, design the structure similar to this technical scheme and embodiment thereof without creationary, all should work as and belong to protection domain of the present utility model.
Claims (4)
1. a cable-flame retardant plugging structure, it is characterized in that, described cable-flame retardant plugging structure comprises cable (1), fireprotection layer (2), back-fire relief bag (3), fire prevention calking (4) and body of wall (5), described fireprotection layer (2) is wrapped in the outside of cable (1), described back-fire relief bag (3) and fire prevention calking (4) are filled in the hole that formed between fireprotection layer (2) and body of wall (4), described fire prevention calking (4) is covered on back-fire relief bag (3), between back-fire relief bag (3) and fireprotection layer (2).
2. a kind of cable-flame retardant plugging structure as claimed in claim 1, is characterized in that described fireprotection layer (2) is fireproof paint.
