Description

A kind of light-duty enhancement type bracket tray formula crane span structure

Technical field

The utility model is a kind of tray type cable bridge for the engineering such as electric power or communication cable cabling, belongs to electrical equipment Accessories technical field.

Background technology

Cable testing bridge is widely used in engineering construction, and by the development of 30 years, product was constantly updated, and is repulsed or subdue the enemy typically from cutting Be worked into the change of cold roll forming, mould pressing process, product structure is from slab construction to ripple struction, molding enhancing riveted structure and High-strength corrugated structure etc., product is set to be obtained for good improvement from effective utilize of performance and resource, but these technologies are also deposited Strengthen riveted structure in deficiency, such as ripple struction and molding and can not be directed to the difference of side plate and bottom plate load distribution of force, effectively Utilize resource；Though high-strength corrugated structure is high to the utilization ratio of sheet material, it is empty also to there is very big improvement in technique and structure Between, if floor length is 250mm, splicing is shorter, and manufacturing procedure is more and cumulative errors are larger, and precision is not high, connecting portion Easily there is gap, splicing position is yielding because sheet material is relatively thin, influences outward appearance, in addition, groove part forms one with side plate, It is not easy to discharge after ponding, influences the antiseptic property and service life of crane span structure.

The content of the invention

Technical problem：The purpose of this utility model is to provide one kind compared with existing product, from heavy and light, intensity height, Yi Jia Work, eliminate cumulative errors, the splicing light-duty enhancement type bracket tray formula that position is unlikely to deform, bottom is not easy ponding, resource utilization is high Crane span structure.

Technical scheme：A kind of light-duty enhancement type bracket tray formula crane span structure of the present utility model is by two blocks of side plates and polylith bottom plate group Into, bottom plate between two blocks of side plates, and continuously splice composition crane span structure along side plate interior sides length direction polylith, baseplate width according to Crane span structure specification is cut off, and the angle of the bottom plate cut-out is beveling, i.e. the horizontal upper plane width of bottom plate is more than lower plane width, makes The transverse width of bottom groove is less than ledge width, to leave a fixed gap in bottom plate and side plate bottom junction, finally will Bottom plate is welded into an entirety with side plate assembly.

The length of every piece of bottom plate is 500mm, and has that multiple tracks is raised, the two-end part that each bottom plate connects folds out 3~ 20mm bottom plate flanging, baseplate width are cut off according to crane span structure specification.The transverse width for making bottom groove is less than ledge width 2 ~15mm.

The side plate and bottom plate use cold roll forming, and side plate selects flat board flanging or reinforced section bar knot according to intensity requirement Structure.

Beneficial effect：Light-duty enhancement type bracket tray formula crane span structure of the present utility model is spelled as a result of length for 500mm bottom plates Connect, the two-end part that bottom plate connects folds out narrow side again, compared with prior art：

First, bulk strength is added.

2nd, mismachining tolerance is eliminated by the method for flanging, ensure that the splicing accuracy of bottom plate, and add bottom edge Intensity, make the position that bottom plate docks not because the thinned of steel plate is deformed, improve the total quality of product, precision and outer See aesthetic degree.

3rd, bottom plate is using the method for beveling, and bottom can be left necessarily when it is connected with the side plate of any pattern Space, on the one hand, prior art uses the method vertically cut off in crane span structure bottom plate, when splicing with side plate, due to being rolled under side plate While being inevitably present rounded corner, the welding position of bossing of bottom plate is seted to produce gap from being adjacent to side plate, cause to weld Connect it is unstable, insecure, need the problem of repair welding, this method can make bottom plate be adjacent to side plate in splicing, solve side plate rounded corner Caused by bossing and side sheet room gap problem, make welding position more solid and reliable, more attractive；On the other hand, due to bottom plate After beveling, with side plate produce a fixed gap, solve non-porous tray crane span structure it is zinc-plated when, bottom plate groove zinc liquid alluvial, be difficult to flow The problem of going out, and product is had more practicality the problem of the ponding of bottom plate groove position during use.

4th, due to when side plate connects bottom can leave a fixed gap so that air inside crane span structure can flow with outside It is dynamic, the radiating effect of crane span structure is added, is advantageous to save.

Embodiment

A kind of light-duty enhancement type bracket tray formula crane span structure of the present utility model is made up of two blocks of side plates 2 and polylith bottom plate 1, side plate 2 Cold roll forming is used with bottom plate 1, and side plate can select the structures such as accompanying drawing 2,4,6,8 according to requirements such as purposes, intensity, and bottom plate 1 is along side The inside length direction polylith of plate 2 continuously splices composition crane span structure, and every piece of floor length is 500mm, the projections 11 of Bing You tetra-, bottom plate phase The two-end part connect folds out 3~20mm double-deck narrow side 13, and the width of bottom plate 1 is cut off according to crane span structure specification, and cut-out angle is oblique Cut, i.e. the horizontal upper plane width of bottom plate 1 is more than lower plane width, the transverse width of bottom groove 12 is less than projection 11 laterally 2~15mm of width, a fixed gap 3 is left in bottom when being connected so as to bottom plate 1 with side plate 2, finally by bottom plate 1 and the assembled weldering of side plate 2 It is connected into an entirety.

Because bottom can leave a fixed gap when bottom plate is connected with the side plate of any pattern, on the one hand, make welding Position is more solid and reliable, more attractive；On the other hand, when solving non-porous tray crane span structure galvanizing by dipping, the alluvial of bottom plate groove zinc liquid, Be difficult to the problem flowed out, and when bottom plate groove position uses the problem of ponding, at the same enable obtain inside crane span structure air with Flows outside, add crane span structure and obtain radiating effect, be advantageous to save.
