Description
Technical field
The present invention is a kind of tray type cable bridge for the engineering such as electric power or communication cable cabling, belongs to electric accessories
Technical field.
Background technology
Cable testing bridge was widely used in engineering construction, by the development of 30 years, and product is 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., makes product be obtained for good improvement from effective utilize of performance and resource, but these technologies are also deposited
In deficiency, such as ripple struction and molding enhancing riveted structure 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, also there is very big improvement in technique and structure empty
Between, such as floor length is 250mm, splices shorter, manufacturing procedure is more and cumulative errors are larger, and precision is not high, connecting portion
Easily there is gap, splicing position is relatively thin due to sheet material, yielding, influences outward appearance, in addition, groove part forms one with side plate,
Discharge is difficult after ponding, the antiseptic property and service life of crane span structure is influenceed.
The content of the invention
Technical problem：The purpose of invention is to provide one kind compared with existing product, from heavy and light, intensity height, easy processing, elimination
Cumulative errors, the splicing light-duty enhancement type bracket tray formula crane span structure that position is unlikely to deform, bottom is difficult ponding, resource utilization is high.
Technical scheme：A kind of light-duty enhancement type bracket tray formula crane span structure of invention is made up of two blocks of side plates and polylith bottom plate, bottom plate
Continuously splice composition crane span structure between two blocks of side plates, and along side plate interior sides length direction polylith, baseplate width is advised according to crane span structure
Lattice are cut off, and the angle of the bottom plate cut-out is that the horizontal upper plane width of beveling, i.e. bottom plate is more than lower plane width, makes bottom recessed
The transverse width of groove is less than ledge width, to leave a fixed gap in bottom plate and side plate bottom junction, finally by bottom plate with
Side plate assembly is welded into an entirety.
The length of every piece of bottom plate is 500mm, and has multiple tracks raised, the two-end part that each bottom plate connects folds out 3~
20mm bottom plate flanging, baseplate width is 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：The light-duty enhancement type bracket tray formula crane span structure of the present invention splices as a result of length for 500mm bottom plates, bottom
The two-end part that 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, it is ensured that the splicing accuracy of bottom plate, and adds bottom edge
Intensity, make the position that bottom plate is docked 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, prevent the welding position of bossing of bottom plate from being adjacent to side plate, produce gap, cause weldering
Connect it is unstable, insecure, the problem of need repair welding, this method can make bottom plate be adjacent to side plate in splicing, solve side plate rounded corner
The bossing caused 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 when using the problem of the ponding of bottom plate groove position, product is had more practicality.
Bottom can leave a fixed gap when the 4th, being connected due to side plate so that the air inside crane span structure can be with outside stream
It is dynamic, the radiating effect of crane span structure is added, is conducive to energy-conservation.

Embodiment
A kind of light-duty enhancement type bracket tray formula crane span structure of the present invention is made up of two blocks of side plates 2 and polylith bottom plate 1, side plate 2 and bottom
Plate 1 uses cold roll forming, and side plate can require the structures such as selection accompanying drawing 2,4,6,8 according to purposes, intensity etc., and bottom plate 1 is along along side plate 2
Side length direction polylith continuously splices composition crane span structure, and every piece of floor length is 500mm, the road projections 11 of Bing You tetra-, what bottom plate connected
Two-end part 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 beveling, 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 raised 11 transverse width 2
~15mm, a fixed gap 3 is left in bottom when being connected so as to bottom plate 1 with side plate 2, and bottom plate 1 and the assembly of side plate 2 finally are welded into one
Individual entirety.
Bottom can leave a fixed gap when being connected due to bottom plate 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 bottom plate groove position is when using the problem of ponding, at the same enable inside crane span structure air with
Flows outside, adds crane span structure and obtains radiating effect, is conducive to energy-conservation.
