Light enhanced tray type bridge stand

Abstract

The invention provides a light enhanced tray type bridge stand. The bridge stand is composed of two side plates (2) and multiple baseplates (1). The baseplates (1) are arranged between the two side plates (2), and multiple baseplates (1) are continuously spliced along the length direction of the internal side of the side plates (2) to form the bridge stand. The width of the baseplates (1) is cut according to the specification of the bridge stand. The cutting angle of the baseplates (1) is inclined, i.e. the width of the transverse upper plane of the baseplates (1) is greater than the width of the lower plane so that the transverse width of bottom grooves (12) is enabled to be less than the width of protrusions (11), a certain gap (3) can be reserved between the bottom connecting part of the baseplates (1) and the side plates (2) and finally the baseplates (1) and the side plates (2) are spliced and welded into an organic whole. Compared with the bridge stands in the prior art, the bridge stand is low in weight, high in strength and easy to process, the cumulative error is eliminated and the splicing part is not liable to deform so that the problem of zinc liquid deposition in the baseplate grooves in hot-dip galvanizing can be solved, water accumulation of the bottom part is not liable to occur and the resource utilization rate is high.

Description

technical field [0001] The invention relates to a tray-type cable bridge used for engineering such as electric power or communication cables, and belongs to the technical field of electrical accessories. Background technique [0002] Cable trays are widely used in engineering construction. After 30 years of development, the products have been continuously updated, from general processing of shearing, folding and punching to cold bending forming and molding process changes. The product structure has changed from flat plate structure to corrugated structure, molded reinforced riveting structure and high strength corrugated. structure, etc., so that the product has been well improved in terms of performance and effective use of resources, but these technologies still have deficiencies, such as corrugated structure and molded reinforced riveted structure, which cannot be effectively used according to the different load distribution of side plates and bottom plates.

[0002] Cable trays are widely used in engineering construction. After 30 years of development, the products have been continuously updated, from general processing of shearing, folding and punching to cold bending forming and molding process changes. The product structure has changed from flat plate structure to corrugated structure, molded reinforced riveting structure and high strength corrugated. structure, etc., so that the product has been well improved in terms of performance and effective use of resources, but these technologies still have deficiencies, such as corrugated structure and molded reinforced riveted structure, which cannot be effectively used according to the different load distribution of side plates and bottom plates. Resources: Although the high-strength corrugated structure has high utilization efficiency of the board, there is still a lot of room for improvement in the process and structure. For example, the length of the bottom plate is 250mm, the splicing is short, there are many processing procedures and the cumulative error is large, and the accuracy is not high. , the connection part is prone to gaps, and the splicing part is thin and easy to deform, which affects the appearance. In addition, the groove part is integrated with the side plate, and it is not easy to discharge after water accumulation, which affects the anti-corrosion performance and service life of the bridge.
