preparation example Construction

[0040] The preparation method of the corrosion-resistant cable bridge plate comprises the following steps:

[0041] S1. Prepare the corrosion-resistant cable bridge plate mold, put the welded steel skeleton into the mold, and set aside;

[0042] S2. Stir and mix the raw materials of the ultra-high-performance concrete in proportion to obtain the ultra-high-performance concrete mixture, and pour it into the mold prepared in step S1, and then perform vibration molding to flatten the surface;

[0043] S3. Cover the cover plate prepared in step S2 with a moisturizing film, remove the mold after curing at room temperature for 24 hours, then perform thermal curing in an environment of 65-85° C. for 24-48 hours, and obtain a corrosion-resistant cable bridge plate after cooling.

[0044] The prepared corrosion-resistant cable bridge plate has good insulation, reduces eddy current and heat generation of cables, good mechanical properties, good corrosion resistance, good durability, good ...

Abstract

The invention discloses a corrosion-resistant cable bridge plate and a corrosion-resistant cable bridge assembled by the same. The corrosion-resistant cable bridge plate is of an ultra-high-performance concrete grating structure and comprises a plurality of crisscrossed main ribs, fastener reserved grooves are formed in the main ribs forming the short edges of the corrosion-resistant cable bridge plate, and the fastener preformed grooves are used for connecting the two adjacent corrosion-resistant cable bridge plates. According to the invention, ultra-high performance concrete is creatively adopted to manufacture the cable bridge plate, and the corrosion-resistant cable bridge plate is manufactured in combination with an ingenious structural design; the cable bridge plate has the advantages of being good in insulativity, capable of reducing eddy current and heating phenomena of the cable, good in mechanical property, corrosion resistance, durability and fire resistance, free of galvanization anti-corrosion treatment, light in weight, diversified in color and the like, stable in size, low in shrinkage, free of aging and other problems, high in structural safety, good in ductility, free of instant brittle failure, wide in material source, and low in the overall comprehensive cost, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of cable tray plates, and more specifically, to a corrosion-resistant cable tray plate and a corrosion-resistant cable tray assembled therefrom. Background technique [0002] With the continuous extension of the cable network and the continuous development of cable tray wiring technology, the demand for cable tray panels will gradually increase. Traditional cable bridge plates include ordinary steel cable bridge plates, stainless steel cable bridge plates and polymer cable bridge plates, but ordinary steel cable bridge plates have the disadvantages of being easy to rust and need grounding devices, and stainless steel cable bridge plates have the disadvantages of cost High, need grounding device, easy to cause the cable to produce eddy current phenomenon and other shortcomings, polymer cable bridge plate has the disadvantages of easy aging, easy deformation, poor fire resistance and so on. [0003] Ultra-hig...
