Abstract
The utility model discloses a high-strength series-connection type steel grating. The high-strength series-connection type steel grating comprises a plurality of longitudinal bars, a plurality of transverse rods, a frame and a cover board, wherein 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, a plurality of transverse rods penetrate through the plurality of one longitudinal bars, crossed portions of the transverse rods and the longitudinal bars are connected in a welded mode, the end portions of the longitudinal bars and the end portions of the transverse rods are connected with the frame in a welded mode, and the longitudinal bars and the cover board are connected with the frame in a welded mode. The high-strength series-connection type steel grating not only is extremely high in structural strength, but also saves electricity.
Description
Technical field
The utility model relates to a kind of high strength series type steel checkerboard.
Background technique
Existing waffle slab is some cross bars and some taeniaes to be arranged in infall in length and breadth be welded.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 high strength series type steel checkerboard, and not only structural strength is high, and compares saving power.
For reaching this purpose, the utility model by the following technical solutions:
A kind of high strength series type steel checkerboard, comprise some taeniaes, some cross bars, a frame, a cover plate, 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 welding of described cross bar and described taeniae, described frame is welded in the end of described taeniae and the end of described cross bar, and described taeniae and described cover plate weld described frame.
Described cross bar adopts spot welding to be connected with the crossover sites of described taeniae.
Described crossbar end is welded described frame sidewall, the described frame of described taeniae end pressure welding.
Described cross bar be arranged in parallel, and described taeniae be arranged in parallel.
Described cover plate end face is provided with anti-slip veins.
Based on disclosing of above technological scheme, the utility model possesses following beneficial effect:
The utility model is 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 on the contrary, is used for welding the electric energy that consumes and but declines to a great extent, advantage is apparent, for preventing the cross bar axial play, cause the cross bar end to be deviate from, the terminal pressure welding frame of taeniae, the sidewall of the end welding frame of cross bar, simultaneously, cover plate is subject to the support of taeniae and frame, and is not only firm in structure, and, owing to do not have the slit on changing, no matter so that the object of what surface of contact needs this steel checkerboard to support, can not go wrong.。
Description of drawings
Fig. 1 is the utility model embodiment 1 overall structure schematic representation:
Fig. 2 is the utility model embodiment 1 exploded view:
Wherein: 1, frame; 2, taeniae; 21, through hole; 3, cross bar; 4, cover plate.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment:
A kind of high strength series type steel checkerboard is proposed, comprise some taeniaes 2, some cross bars 3, a frame 1, a cover plate 4, offer some through holes 21 on the taeniae 2, cross bar 3 passes the through hole 21 on some taeniaes 2, some through holes 21 of a taeniae 2 are passed by some cross bars 3, cross bar 3 welds with the crossover sites of taeniae 2, the end welding frame 1 of the end of taeniae 2 and cross bar 3, taeniae 2 and cover plate 4 welding frames 1.Cross bar 3 adopts spot welding to be connected with the crossover sites of taeniae 2.Cross bar 3 ends welding frame 1 sidewall, taeniae 2 end pressure welding frames 1.Cross bar 3 be arranged in parallel, and taeniae 2 be arranged in parallel.Cover plate 4 end faces are provided with anti-slip veins.
Because cross bar 3 passes the through hole 21 on the taeniae 2, so that the activity space of cross bar 3 itself is subject to taeniae 2, joining place spot welding that only need to be between cross bar 3 and taeniae 2, can be so that be connected enough firm between cross bar 3 and the taeniae 2, and directly cross bar 3 and taeniae 2 are welded together with respect to way of the prior art, its structural strength significantly increases, and on the contrary, is used for welding the electric energy that consumes and but declines to a great extent, advantage is apparent, for preventing cross bar 3 axial play, cause cross bar 3 ends to be deviate from, the terminal pressure welding frame 1 of taeniae 2, the sidewall of the end welding frame 1 of cross bar 3, simultaneously, cover plate 4 is subject to the support of taeniae 2 and frame 1, and is not only firm in structure, and, owing to do not have the slit on changing, no matter so that the object of what surface of contact needs this steel checkerboard to support, can not go wrong.
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.
