CN202353142U - Fire screen structure for bus duct - Google Patents

Abstract

The utility model discloses a fire screen structure for a bus duct. The fire screen structure for the bus duct comprises the bus duct. Two layers of fire-retardant plates are arranged on the outer surface of the bus duct. The bus duct is fixedly connected with the fire-retardant plates through a refractory sealant. A plurality of fixing devices are arranged outside the fire-retardant plates. The two layers of fire-retardant plates are arranged on a housing of the bus duct, all gaps are filled with the refractory sealant in a mounting process, finishing fire-retardant paint is brushed on the surfaces of the fire-retardant plates after the fire-retardant plates are arranged, the fire-retardant plates are made from fiber reinforced silicate which is an A-class incombustible material with low thermal conductivity, and when a fire happens, the structure forms a thermal insulating layer to prevent a bus duct body material from being melted and prevent flame and heat from being transferred from one side to the other side of a wall body along the bus duct, so that the fire can be effectively prevented from being spread along the bus duct when the fire happens, the coverage of the fire is narrowed, and the safety performance of a bus duct system can be greatly improved.

Description

A kind of bus duct fire screen structure

Technical field

The utility model relates to a kind of shell the bus duct of the PLASTIC LAMINATED structure through walls of preventing fires is installed, and specifically, relates to a kind of bus duct fire screen structure, belongs to transmission facility accessory technical field.

Background technology

In recent years, along with cable is that bus duct catches fire and prolongs increasing of combustion accident, like power plant, transformer station, telecommunications room, Mobile Telecommunication Equipment Room, building etc.Because forceful electric power cable, light current number of cables are numerous, lays intensive and discrepancy in elevation ratio cable shaft, formation natural air exhaust; The cable tunnel narrow space that has is if in a single day these places catch fire, when can not get effectively stoping; The intensity of a fire will enlarge the fire scope, until burning out whole equipment room, base station along the combustion of cable group delay; Cause power failure or communication disruption etc., will cause enormous economic loss.

The utility model content

To the above-mentioned deficiency that prior art exists, the purpose of the utility model provides the bus duct fire screen structure of a kind of simple, good stability with low cost, rational in infrastructure, not yielding, light, convenient processing and installation.

For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:

A kind of bus duct fire screen structure comprises bus duct, and its bus duct outer surface is equipped with two-layer PLASTIC LAMINATED, is fixedly connected through fire resistant sealant between bus duct and the PLASTIC LAMINATED; The said PLASTIC LAMINATED outside is provided with the plurality of fixed device.

As further preferred version, described fixture comprises shroud ring and following shroud ring, and last shroud ring is connected through the bolt that is arranged on its both sides with following shroud ring.

As further preferred version, described PLASTIC LAMINATED surface is provided with the finishing fire retardant paint layer.

As further preferred version, described PLASTIC LAMINATED adopts the fiber reinforcement silicate board.

Compared with prior art, the utility model is through installing two-layer PLASTIC LAMINATED at the bus duct shell, and the fire resistant sealant that in installation process, adopts heatproof to reach 1250 ℃ to all slits is crammed; Integral installation finishes the back to PLASTIC LAMINATED surface brush finishing fire retardant paint, and PLASTIC LAMINATED adopts the fiber reinforcement silicate board, and this material is that A level incombustible material and conductive coefficient are lower; When fire takes place; This structure forms the thick thermal insulation layer of 40mm, prevents that the bus duct bulk material from melting, and one side is delivered to opposite side along bus duct from body of wall to stop flame and heat; Can, fire effectively stop the intensity of a fire to prolong combustion when taking place along bus duct; Reduce the fire scope, reduce economic loss, can significantly improve the security performance of bus duct system.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.

To shown in Figure 4, a kind of bus duct fire screen structure that the utility model provides comprises bus duct 1 like Fig. 1, and its bus duct 1 outer surface is equipped with two-layer PLASTIC LAMINATED 3, is fixedly connected through fire resistant sealant between bus duct 1 and the PLASTIC LAMINATED 3; Said PLASTIC LAMINATED 3 outsides are provided with the plurality of fixed device.Said fixture comprises shroud ring 2 and following shroud ring 4, and last shroud ring 2 is fixedly connected through the bolt 5 that is arranged on its both sides with following shroud ring 4.PLASTIC LAMINATED 3 surfaces are provided with finishing fire retardant paint layer 6.PLASTIC LAMINATED 3 adopts the fiber reinforcement silicate board.

The utility model is through installing two-layer PLASTIC LAMINATED at the bus duct shell, and the fire resistant sealant that in installation process, adopts heatproof to reach 1250 ℃ to all slits is crammed, and integral installation finishes the back to PLASTIC LAMINATED surface brush finishing fire retardant paint; PLASTIC LAMINATED adopts the fiber reinforcement silicate board; This material is that A level incombustible material and conductive coefficient are lower, and when fire took place, this structure formed the thick thermal insulation layer of 40mm; Prevent that the bus duct bulk material from melting; One side is delivered to opposite side along bus duct from body of wall to stop flame and heat, can when fire takes place, effectively stop the intensity of a fire to prolong combustion along bus duct, reduces the fire scope; Reduce economic loss, can significantly improve the security performance of bus duct system.

Be necessary at last to be pointed out that at this; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also is not limited to above-mentioned giving an example, and those skilled in the art is in the essential scope of the utility model; The variation of having done, remodeling, interpolation or replacement all will belong to the protection range of the utility model.
