Description
Technical field
The present invention relates to cable testing bridge field, and in particular to a kind of cable testing bridge with fire-proof function.
Background technology
Cable testing bridge system is the class staple product in manufacturing industry, is to be used for specification, protection in each infrastructure project
The main equipment of cable and transmission line safety.General cable testing bridge is from high-quality is cold rolling or the steel plate such as hot rolling, heat zinc coating plate.By
Non-ignitable in steel construction itself, the fire safety problem of steel construction was once once being ignored by people.Report and have according to domestic and international relevant information
The experiment of shutting mechanism and statistics show that the mechanical strength of steel construction is reduced with the rise of temperature, at 500 DEG C or so, its
Intensity drops to 40%~50%, the mechanical property of steel construction, such as yield point, compression strength, modulus of elasticity and load energy
Power etc. is all rapid to be declined, and enabling capabilities are lost quickly, cause crane span structure to collapse.Therefore, steel construction is carried out protecting imperative.Steel
Structure fire coating is brushed or is sprayed on steel structure surface, is played fire-proof and thermal-insulation, is prevented steel construction to be brought rapidly up in a fire
And reducing intensity, it is to avoid steel construction loses enabling capabilities and causes crane span structure to collapse.
The content of the invention
In order to solve problems of the prior art, the invention provides a kind of cable testing bridge with fire-proof function,
With higher fire protecting performance, while alarm can be sent when occurring fire.
Technical proposal that the invention solves the above-mentioned problems is：A kind of cable testing bridge with fire-proof function, including crane span structure sheet

One separation trough and the 4th separation trough specular, the second separation trough are identical with the 3rd separation slot structure, and the first separation trough is circular arc
The first dividing plate, second partition, some 3rd dividing plates, the 4th dividing plate, the first dividing plate, second are provided with shape structure, the first separation trough
Dividing plate, the 3rd dividing plate, the cross sectional shape of the 4th dividing plate are rectangle, and the 3rd dividing plate is vertically arranged with the first separation trough, first every
Plate, second partition, some 3rd dividing plates, the 4th diaphragm rings are around the first cable trough is formed, and the section of the first cable trough is circular arc,
Second separation trough includes 2 the 5th dividing plates, some 6th dividing plates, and the structure of the 5th dividing plate is identical with the 4th dividing plate, the 6th dividing plate
Structure it is identical with the 3rd dividing plate, the 5th dividing plate, the 6th dividing plate enclose to form the second cable trough, size, the shape of the second cable trough
Shape is identical with the first cable trough.
The lower surface of the bottom plate is provided with link slot, and the section of link slot is isosceles trapezoid, and the quantity of link slot is 3,
The distance between adjacent coupling slots are equal.
The bottom plate is provided with first through hole, the second through hole, and first through hole is rectangular configuration, and the second through hole is tied to be circular
Structure, first through hole, the second through hole are arranged alternately on the length direction of crane span structure body, and first through hole is in the width side of crane span structure body
It is placed equidistant upwards, the second through hole is placed equidistant on the width of crane span structure body.
The lower surface of the bottom plate is provided with temperature sensor, Smoke Sensor, and temperature sensor, Smoke Sensor are located at phase
The centre position of adjacent first through hole.
The crane span structure body is provided with fireproof coating, and the preparation process of the fireproof coating is as follows：
(1) in terms of weight fraction, 100-120 parts of inorganic filler, 20-40 parts of binding agent, 50-80 parts of n-butanol, increasing are weighed
Mould 10-20 parts of agent, 10-20 parts of drier, 20-40 parts of fire retardant, 10-20 parts of preservative；
(2) preservative, n-butanol, binding agent are added into stirrer for mixing uniformly, whipping temp is 50-70 DEG C, stirring
