In the utility model, the sealing strips have the function of sealing and water proofing, thereby preventing the cable from being corroded; the fireproof heat dissipation function is achieved through the fireproof net and the heat dissipation and dissipation holes.
Description
Technical Field
The utility model belongs to the technical field of the installation of cable testing bridge, especially, relate to a cable testing bridge.
Background
The cable bridge is widely applied to the erection of cables in electric power, communication and lighting systems, and the conventional universal cable bridge adopts metal plates which are directly pressed into an integrated groove shape or box shape, occupies larger space, has low transportation efficiency and is limited by materials, and is not easy to be reprocessed on the installation site to adapt to the requirements of specific installation. In addition, the metal plate (generally a steel plate) has the defect of easy rusting, and particularly in wet coastal urban underground engineering, the metal plate is easy to rust and corrode, so that the service life of the cable in the bridge is influenced. And the existing cable bridge frame also has the defect of no fire prevention, and once a fire disaster happens, the steel plate has fast heat conduction, so that the cable is easily ignited to catch fire.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: to the problem that exists, the utility model provides a leakproofness is good, waterproof cable corrodes, has the cable testing bridge of heat dissipation fire prevention function simultaneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a cable bridge, includes crane span structure body and apron, the top detachable fixed mounting apron of crane span structure body, crane span structure body both sides are equipped with fixture block and seal groove respectively, and the both sides of apron bottom are equipped with the fastener that corresponds with the fixture block respectively to and the sealing strip that corresponds with the seal groove, and the bottom of crane span structure body still is equipped with the one deck fire prevention net, and the top of fire prevention net is equipped with the division board, and a plurality of circular louvres are seted up to the bottom of crane span structure body.
Further, the heat dissipation holes are circular heat dissipation holes.
The fireproof net is of a metal grid structure. The fireproof net of the metal grid has a good fireproof effect, and meanwhile, air circulation and heat dissipation are enhanced.
Furthermore, the area of a single grid of the fireproof net is 10-20 mm2。
And the surface of the fireproof net is coated with a layer of intumescent fireproof coating. The fireproof net coated with the intumescent fireproof coating is added, so that the good heat dissipation performance can be maintained, and meanwhile, the grids of the fireproof net can be quickly sealed when the fireproof net meets fire, so that the fireproof net has good flame-retardant and fireproof capabilities.
Furthermore, the bottom of crane span structure body is seted up in the even distribution of louvre. The heat dissipation performance is better by uniform distribution.
Furthermore, the diameter of the heat dissipation holes is 20-30 mm.
The beneficial effects of the utility model reside in that:
1. the utility model discloses in, the sealing strip through setting up has sealed waterproof effect, prevents that the cable from corroding.
2. The utility model discloses in, have the radiating effect of fire prevention through fire prevention net and heat dissipation louvre.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: the bridge structure comprises a cover plate 1, a bridge frame body 2, a partition plate 3, a sealing strip 4, a clamping block 5, a fireproof net 6 and a sealing groove 7.
Detailed Description
The technical solution of the present invention is further described below, but the scope of protection claimed is not limited thereto.
As shown in fig. 1, a cable bridge, including crane span structure body 2 and apron 1, the top detachable fixed mounting apron 1 of crane span structure body 2, crane span structure body 2 both sides are equipped with fixture block 5 and seal groove 7 respectively, the both sides of apron 1 bottom are equipped with the fastener that corresponds with fixture block 5 respectively to and the sealing strip 4 that corresponds with seal groove 7, the bottom of crane span structure body 2 still is equipped with one deck fire prevention net 6, the top of fire prevention net 6 is equipped with division board 3, a plurality of circular louvres are seted up to the bottom of crane span structure body 2.
The heat dissipation holes are circular heat dissipation holes.
The fireproof net 6 is of a metal grid structure. The fireproof net 6 of the metal grid has a good fireproof effect, and meanwhile, air circulation and heat dissipation are enhanced.
The area of 6 single grids of the fireproof net is 10-20 mm2。
The surface of the fire-proof net 6 is coated with a layer of expansion type fire-proof paint. The fireproof net 6 coated with the expansion type fireproof coating is additionally arranged, so that good heat dissipation performance can be kept, and meanwhile, the grids of the fireproof net 6 can be quickly sealed when the fireproof net meets fire, so that the fireproof net has good flame-retardant and fireproof capabilities.
The bottom of crane span structure body 2 is seted up to the even distribution of louvre. The heat dissipation performance is better by uniform distribution.
The diameter of the heat dissipation holes is 20-30 mm.
In this scheme, prevent the cable on division board 3, through installing sealing strip 4 on seal groove 7, because water is down drippage, so sealing strip 4 lives apron 1 down the water seal of downing, can not deepen in apron 1, fine waterproof effect has, fixture block 5 makes the crane span structure body 2 be connected more firm with apron 1 with being connected of fastener, fire prevention net 6 has very high fire prevention effect, and the louvre has the radiating effect to the cable crane span structure, prevent that the inside high temperature of cable crane span structure, this cable crane span structure has waterproof and fireproof's effect simultaneously.
