Description
[affiliated technical field]
The utility model relates to the auxiliary erection instrument of a kind of electric power, telecommunication system use, relates in particular to the structure improved cable testing bridge that a kind of cabling is used.
[background technology]
Crane span structure is the necessary supporter of cabling, with cable laying in crane span structure, clean and tidy safety again.The cable testing bridge of prior art is normally made of metal material.Crane span structure divides base and two parts of lid, and base and lid all are the U-shaped structure, and the sidewall height of base is greater than the covered body wall height.During cabling, earlier the cable testing bridge base is installed on the crossbeam or carriage that supports crane span structure, then cabling in crane span structure.After cable laying finishes, on cover cap, base and lid are linked together with connectors such as strapping, buckle or screws.The shortcoming of this crane span structure is higher laying of cable, the especially power cable of influencing of base side wall.Because weight is big, operation intensity is big, and the base side wall height is vulnerable to collision, even damages.In addition, cable testing bridge uses metal material (iron sheet) to be made usually, the conductive coefficient height, and breaking out of fire easily simultaneously, is easily got rusty, is corroded, and useful life is short.
[summary of the invention]
The purpose of this utility model is to provide a kind of structure improved cable testing bridge, the sidewall height of base is less than the covered body wall height, even it highly is zero, and the covered body wall height is improved, make things convenient for laying of cable, be difficult for bumping with base side wall, simultaneously, the top layer of crane span structure is a glass fibre magnesia oxychloride cement bridge layer, and conductive coefficient is low, corrosion-resistant, the base side wall height that solves the prior art existence also solves the conductive coefficient height simultaneously greater than the existing problem of covered body wall height, easily breaking out of fire, and easily get rusty, corrode, useful life is than problems such as weak points.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: structure improved cable testing bridge, comprise base, the lid that cooperates with base, the cross section that it is characterized in that described lid is a U-shaped, and the height of this covered body wall is greater than the height of corresponding sidewall on the base.The sidewall height of base is less than the covered body wall height, even the height of base side wall is zero, and the covered body wall height is improved, can hold cable smoothly, and make things convenient for laying of cable, be difficult for bumping, the appearance of clashing and breaking phenomenon also just can not occur with base side wall.
As the further of technique scheme improved and replenish, the utility model adopts following technical measures:
The cross section of described base is the U type, and the height of this base side wall is less than the height of covered body wall.The sidewall height of base is very little, can prevent that the cable that is applied on the base from skidding off, and conveniently cover cap is set on the base.Simultaneously, during cabling, also be not easy to bump with base side wall,
Described base and lid are glass fibre magnesia oxychloride cement U-shaped plate.Conductive coefficient is low, and is corrosion-resistant, helps avoiding the generation of fire, can increase the service life simultaneously.
Described base is plate shaped, comprises upward deposited plate and lower shoe that the gap is provided with, and described gap forms thermal insulation layer.Under the prerequisite that satisfies the crane span structure function of use, base is plate shaped, and simultaneously the covered body wall height improves, when having avoided cabling basically and the possibility that bumps of base side wall.The normal conditions lower bottom base is that double-layer structure just can meet the demands, and leaves the space between layer and the layer, forms thermal insulation layer.The formation of thermal insulation layer has effectively reduced the conductive coefficient of base, makes the burning that is difficult for being heated of cable in the cable testing bridge, has excellent fireproof performance, has effectively reduced the possibility of breaking out of fire.Generally, thermal insulation layer can be air heat-insulation layer, can also play heat-blocking action for other light fire-proof heat-insulating layers.Go up the thermal insulation layer that applies between plate and the lower shoe and have certain height, make thermal insulation layer have good effect of heat insulation, further reduce the conductive coefficient of crane span structure, improved the coefficient safe in utilization of this cable testing bridge.
Described deposited plate and lower shoe are glass fibre magnesia oxychloride cement plate, described lid is for by three affixed U-shaped composite laminboards that form of composite laminboard, and described composite laminboard comprises cystosepiment, is compounded in the glass fibre magnesia oxychloride cement plate on cystosepiment two sides respectively.Going up the manufacturing materials of applying plate, lower shoe and lid two top layers all is the glass fibre magnesia oxychloride cement, conductive coefficient is low, further reduced hot conduction, made the lead in the cable testing bridge more be difficult for the burning of being heated, the possibility of having avoided fire to take place basically; In addition, crane span structure also is difficult for getting rusty, even also do not corrode long service life under wet environment.
Described thermal insulation layer is the cystosepiment thermal insulation layer.Cystosepiment has effect of heat insulation.
Described cystosepiment and cystosepiment thermal insulation layer are the magnesia oxychloride cement polystyrene foam plate, and described magnesia oxychloride cement polystyrene foam plate is made up of numerous foam particle, and the surface of each foam particle is coated with the magnesia oxychloride cement layer.In the magnesia oxychloride cement polystyrene foam plate, magnesia oxychloride cement becomes the adhesive that foam particle is bonded into cystosepiment, is again foam particle is produced fire retardation, whole crane span structure is reached do not fire the A level.
Described thermal insulation layer is an air heat-insulation layer, and described going up between deposited plate and the lower shoe is provided with reinforcement.Under the situation of crane span structure size broad, can set up reinforcement, double-deck base is gained in strength, help strengthening the intensity of base, can bear bigger weight.Reinforcement wherein can be platy structure, and it is consistent with the crane span structure length direction that direction is set, and when making with on apply plate and the disposable making of lower shoe is shaped, form integrative-structure, can reduce the product manufacturing procedure, reduce labour intensity.
The beneficial effect that the utlity model has: 1, the sidewall height of base is less than the covered body wall height, even it highly is zero, and the covered body wall height is improved, and makes things convenient for laying of cable, is difficult for and base side wall bumps, and avoids crane span structure bad by clashing and breaking; 2, the top layer of base and lid all is the glass fibre magnesia oxychloride cement, conductive coefficient is low, and, be formed with thermal insulation layer on the base, even the material of thermal insulation layer is the magnesia oxychloride cement polystyrene foam plate, can also reach and not fire the A level under the low prerequisite of thermal conductivity guaranteeing, make the lead in the cable testing bridge not be subjected to extraneous thermal impact basically, the possibility of having avoided cable fire to take place basically; 3, the cable testing bridge of nonmetallic materials also is difficult for getting rusty, even also do not corrode long service life under wet environment.
