Abstract
The utility model discloses a falling-prevention serial-connection type steel grating. The falling-prevention serial-connection type steel grating comprises a plurality of longitudinal bars and a plurality of transverse rods, each longitudinal bar is provided with a plurality of through holes, one transverse rod penetrates through the through holes of a plurality of longitudinal bars, and a plurality of transverse rods penetrate through the plurality of through holes of each longitudinal bar. The cross portions of the transverse rods and the longitudinal bars are fixed in a welded mode, the tail ends of the transverse rods are welded to the side walls of the longitudinal bars, and the section area of each welding position of each tail end is larger than that of each transverse rod. According to the falling-prevention serial-connection type steel grating, not only can structural strength of the falling-prevention serial-connection type steel grating be greatly improved, but also consumed energy during the production processes of the falling-prevention serial-connection type steel grating can be reduced.
Description
Technical field
The utility model relates to a kind of Drop-proof series type steel checkerboard.
Background technique
Existing steel checkerboard is that some cross bars and some taeniaes are arranged in length and breadth, is welded at infall.Wherein, taeniae generally adopts band steel, and cross bar generally adopts round steel or fried dough twist steel.There is following defective in the steel checkerboard of this structure: not only intensity is not high, and wastes a large amount of electric energy in welding process.
The model utility content
For the problem that prior art exists, the purpose of this utility model is to propose a kind of Drop-proof series type steel checkerboard, and its enforcement not only can significantly promote its structural strength, and can reduce its energy consumption in process of production.
For reaching this purpose, the utility model by the following technical solutions:
A kind of Drop-proof series type steel checkerboard, comprise some taeniaes, some cross bars, offer some through holes on the described taeniae, described cross bar passes the described through hole on some taeniaes, the some described through hole of a described taeniae is passed by some described cross bars, the crossover sites of described cross bar and described taeniae is welded and fixed, the end of described cross bar and the welding of the sidewall of described taeniae, and the sectional area of the weld of described end is greater than the sectional area of described cross bar.Described cross bar is arranged in parallel, and described taeniae is arranged in parallel.The top of described taeniae is provided with anti-slip veins.
Based on disclosing of above technological scheme, the utility model possesses following beneficial effect:
The utility model is in implementation process, because cross bar passes the through hole on the taeniae, so that the activity space of cross bar itself is subject to taeniae, joining place spot welding that only need to be between cross bar and taeniae, can be so that be connected enough firm between cross bar and the taeniae, and directly cross bar and taeniae are welded together with respect to way of the prior art, its structural strength significantly increases, and it declines to a great extent for the electric energy that welding consumes, advantage is apparent, for preventing the cross bar axial play, causes cross bar to be deviate from, the terminal directly welding taeniae sidewall of cross bar, in addition, more firm for making welding, the sectional area at the position that the end of cross bar and taeniae weld is greater than the sectional area of cross bar, make bonding area increase between the two, improve to greatest extent the structural strength of product.
Description of drawings
Fig. 1 is the utility model embodiment 1 part-structure schematic representation:
Fig. 2 is the utility model embodiment 1 part-structure schematic representation:
Fig. 3 is the utility model embodiment 1 part-structure schematic representation:
Wherein: 1, taeniae; 11, through hole; 12, anti-slip veins; 2, cross bar; 21, end.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment:
A kind of Drop-proof series type steel checkerboard, comprise some taeniaes 1, some cross bars 2, offer some through holes 11 on the taeniae 1, cross bar 2 passes the through hole 11 on some taeniaes 1, some through holes 11 of a taeniae 1 are passed by some cross bars 2, cross bar 2 is welded and fixed with the crossover sites of taeniae 1, and the end 21 of cross bar 2 welds with the sidewall of taeniae 1, and the sectional area of terminal 21 weld is greater than the sectional area of cross bar 2.Cross bar 2 is arranged in parallel, and taeniae 1 is arranged in parallel.The top of taeniae 1 is provided with anti-slip veins 12.
Because cross bar 2 passes the through hole 11 on the taeniae 1, so that the activity space of cross bar 2 itself is subject to taeniae 1, joining place spot welding that only need to be between cross bar 2 and taeniae 1, can be so that be connected enough firm between cross bar 2 and the taeniae 1, and directly cross bar 2 and taeniae 1 are welded together with respect to way of the prior art, its structural strength significantly increases, on the contrary, being used for welding the electric energy that consumes but declines to a great extent, advantage is apparent, for preventing cross bar 2 axial play, cause cross bar 2 ends to be deviate from, the end 21 of cross bar 2 directly welds taeniae 1 sidewall, simultaneously, for making welding more firm, the end 2 of cross bar 2 and the sectional area of the bonding area of taeniae 1 greater than cross bar 2, thus improve to greatest extent its structural strength.
The above; it only is the better embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and model utility design thereof, all should be encompassed within the protection domain of the present utility model.
