Abstract
The utility model discloses a blocking structure of a cable reserved hole of a floorslab. The blocking structure comprises a floorslab (6) for installing a power control cabinet (7), wherein the floorslab (6) is provided with a cable reserved hole (6.1) for a cable (5) led out from the power control cabinet (7) to penetrate through, a cable composite fire-resistant shield (3) capable of being sleeved on the cable (50 is fixed on the bottom surface of the floorslab (6) through a bolt, and a gap between the cable composite fire-resistant shield (3) and the cable (5) is filled with a flexible organic elastic fireproof sealant (2). In the utility model, with the adoption of a construction method of the cable composite fire-resistant shield, light-weight expanded organic fireproof blocking materials and the flexible organic elastic fireproof sealant, the defect of unreliability of the adoption of a fine concrete blocking method is overcome, and the construction can be conveniently carried out from the lower part of the floorslab. The blocking structure not only has the advantages of simple structure, convenient construction and high blocking reliability, but also has the advantages of long service life, good fireproof performance and the like.
Description
Technical field
The utility model relates to a kind of plugging structure of floor cable hole to be provided, belongs to the blocking technology field of cable box out.
Background technology
Electrical power distribution chamber floor or cable shaft have the cable box out usually in industry and civilian construction.By the requirement of " Code for fire protection design of buildings ", flame and flue gas are by the cable box out Es-region propagations that makes progress when preventing that fire from taking place, and the cable box out must be carried out shutoff.Present practices well is to carry out simple shutoff with pea gravel concreten after cable laying finishes.But because adhesion stress is relatively poor usually between the cable box out of pea gravel concreten and reservation, can produce big slit, even dropping situations takes place, therefore the plugging structure of existing cable box out and unreliable.
Summary of the invention
The purpose of this utility model is: provide the plugging structure of the high floor cable box out of a kind of simple in structure, easy construction and shutoff reliability, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: the plugging structure of a kind of floor cable of the present utility model box out, comprise the floor that is used to install electric control cabinet, on floor, be provided with the cable box out that is used to pass the cable of drawing from electric control cabinet, on the bottom surface of floor, the cable that can be enclosed within on cable composite fire dividing plate is arranged, and be filled with flexible organic elastomer fireproof seal gum with place, the slit between composite fire dividing plate and the cable at cable by bolt.
Between the hole wall of above-mentioned cable and cable box out, also be filled with lightweight expansion type organic fire prevention calking.
Also be coated with one deck fire retardant coating of aquosity cable layer at above-mentioned cable on the cable below beyond the composite fire dividing plate, and the overlay length of fire retardant coating of aquosity cable layer is not less than 1.0 meters for the surface from the composite fire dividing plate.
Owing to adopted technique scheme, the building method of the utility model employing cable usefulness composite fire dividing plate and lightweight expansion type organic fire prevention calking, flexible organic elastomer fireproof seal gum, overcome the insecure shortcoming of employing pea gravel concreten method for blocking, and can be from the construction of floor bottom, it is very convenient to construct.Therefore, the utility model compared with prior art, that the utility model not only has is simple in structure, easy construction, advantage that the shutoff reliability is high, but also has advantages such as long service life, fireproof performance be good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals:
1-lightweight expansion type organic fire prevention calking, the flexible organic elastomer fireproof seal gum of 2-, 3-cable composite fire dividing plate, 4-fire retardant coating of aquosity cable layer, 5-cable, 6-floor, the box out of 6.1-cable, 7-electric control cabinet.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: the plugging structure of a kind of floor cable box out that the utility model is new can be directly used in implementing on the existing floor 6 that electric control cabinet 7 is installed, on floor 6, leave the cable box out 6.1 that is used to pass the cable 5 of drawing from electric control cabinet 7 in advance, during enforcement, can be enclosed within cable on the cable 5 on the bottom surface of floor 6 on by bolt with composite fire dividing plate 3, and cable with place, the slit filling between composite fire dividing plate 3 and the cable 5 on flexible organic elastomer fireproof seal gum 2; In order to reach more reliable performance, between the hole wall of cable 5 and cable box out 6.1, fill full lightweight expansion type organic fire prevention calking 1; In order to obtain better flameproof effect, can cable with composite fire dividing plate 3 beyond below cable 5 on cover last layer fire retardant coating of aquosity cable layer 4, and the overlay length L of fire retardant coating of aquosity cable layer 4 be controlled at the scope that is not less than 1.0 meters from the surface of composite fire dividing plate 3 get final product.
The lightweight expansion type organic fire prevention calking 1 that the utility model adopted, flexible organic elastomer fireproof seal gum 2, cable are existing finished-product material of the prior art with composite fire dividing plate 3 and fire retardant coating of aquosity cable layer 4.
