Problems solved by technology
The disadvantage of the current mesh cable tray is that when the tray is long (longitudinal span is large), its bending resistance is not enough, resulting in deformation of the tray, and there is no device for separating cables in the tray, resulting in inconvenient cable layout.
In addition, when the existing mesh bridge is used for welding the steel wires of the bridge, there is a problem of difficult assembly due to the large tolerance of the welded parts.

Embodiment Construction
[0022] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0023] like figure 1 as shown, Figure 4 and Figure 5 As shown, the present invention includes a body with an integrated structure. The body includes a bottom plate 3 formed by bending, a side plate 1 and a top plate 2 with a flange 21, and the flange 21 is located on the lower side of the top plate 2; the bottom plate 3 has a longitudinal slot 31 and a plurality of transverse fractures 33, the transverse fracture 33 divides the bottom plate 3 into multiple units; the longitudinal clamping groove 31 is used for buckling the longitudinal steel wire of the bridge, and the longitudinal clamping groove 31 is formed by bending the bottom plate 3, which separates the bottom plate 3 into The inner bottom plate 34 and the outer bottom plate 35, the inner bottom plate 34 is generally perpendicular to the side plate 1, the outer bottom plate 35 i...

The invention relates to an enhancing accessory of a grid type bridge frame. The enhancing accessory comprises a body with an integrated structure, wherein the body comprises a bottom plate, a side plate and a top plate which are molded by bending; the bottom plate is provided with a longitudinal clamping groove and a plurality of horizontal fractures; first gaps are formed in the connecting position of the side plate and the bottom plate and are communicated with the horizontal fractures; at the horizontal fractures, the bottom plate is provided with longitudinal supporting plates; at the two ends of the body, the side plate is provided with a lower connecting hole and an upper connecting hole. The enhancing accessory has the characteristics of simple structure, light weight and convenience in installation and processing, and has the beneficial effects that when the enhancing accessory is arranged on a cable bridge frame, the bearing capability of the cable bridge can be greatly improved; by distribution of the first longitudinal supporting plate and the second longitudinal supporting plate, the problem that when steel wires of the bridge frame are welded, the assembly can not be implemented or is difficult due to dimensional tolerance change is solved and the distribution of cables is optimized.
Description
technical field [0001] The invention relates to a grid-type cable tray, in particular to a reinforcing accessory for the grid-type bridge. Background technique [0002] At present, the mesh bridge tray has been proved to be an ideal choice for any type of cable laying, especially for data centers, research and development centers, food and beverage industries, power plants and power stations, chemical and pharmaceutical industries, high-tech office buildings, shipbuilding industries, infrastructure and mobile communication systems, etc. Grid bridge has been accepted by more and more users all over the world. With its excellent flexibility and safety, it has become an ideal product to replace traditional closed bridge. [0003] The existing grid-type cable tray is generally composed of vertical and horizontal steel wires, and is a grid-shaped hollow structure, which can be made into various forms according to the construction situation. The disadvantages of the current mesh...
