Abstract
The utility model belongs to the two-sided cross bar steel grating of a kind of strengthen rigidity and intensity.Problem to be solved is exactly that background technology exists：Steel grating only welds cross bar on an upper, each band steel lacks structural contact between lower surface, cause overall rigidity and intensity deficiency, under the action of long-term car such as rolls at the alternate load, particularly when band steel width is larger, carrying band steel lower part easily occurs to side to topple over, so that the problem of causing local buckling, cross bar to come off.Drip irrigation device is used by solving the technical problem：The two-sided cross bar steel grating of a kind of strengthen rigidity and intensity, welds some cross tubes, it is characterised in that weld some sheer poles in the lower surface of band steel by the upper surface of spacing arrangement band steel.The utility model is suitable for the occasions such as the platform bed board, municipal well lid and the cover board in ditch of structural steelwork.
Description
Technical field the utility model belongs to new steel structure material, and particularly a kind of strengthen rigidity and intensity is two-sided
Cross bar steel grating.
The basic structure of the existing steel grating of background technology is：Some uniformly rows of upper surface welding of some evenly distributed band steels
The cross tube of row, forms some grid-like slab constructions.Widely apply the platform bed board in structural steelwork, municipal well lid and
The occasions such as the cover board in ditch.Since this steel grating only welds cross bar on an upper, each band steel lacks knot between lower surface
The contact of structure, causes overall rigidity and intensity deficiency, under the action of long-term car such as rolls at the alternate load, particularly works as
When band steel width is larger, carrying band steel lower part easily occurs and topples over to side, asked so as to cause local buckling, cross bar to come off etc.
Topic.
Content of the invention the purpose of this utility model is exactly to propose the two-sided cross bar steel grating of a kind of strengthen rigidity and intensity, with
Background technology is solved to exist：Steel grating only welds cross bar on an upper, and each band steel lacks structural connection between lower surface
System, causes overall rigidity and intensity deficiency, under the action of long-term car such as rolls at the alternate load, particularly when band steel width
When larger, carrying band steel lower part easily occurs and topples over to side, so that the problems such as causing local buckling, cross bar to come off.Solving should
Technical solution is used by technical problem：The two-sided cross bar steel grating of a kind of strengthen rigidity and intensity, band steel is arranged by spacing
Upper surface weld some cross tubes, it is characterised in that weld some sheer poles in the lower surface of band steel.Wherein, some cross tubes with
Some sheer poles formed up and down staggeredly it is evenly distributed.Hound is set between adjacent cross tube and sheer pole.
Possessed beneficial effect is the utility model compared with the prior art：Due to the adoption of the above technical scheme, it is each flat
Couple between the surfaces by some sheer poles under steel so that steel grating forms the overall structure of two-sided cross bar, significantly improves
The rigidity and intensity of steel grating.When load action is in steel grating upper surface, cross tube is pressurized, sheer pole tension, forms stress
Isostatic compensation, hound then support the rigidity for adding entire plate, result in formation of rational overall force structure, effectively solve
Existing steel grating the problems such as caused by alternate load local buckling, cross bar come off such as rolls due to automobile.
Brief description of the drawings：Fig. 1 is the structure diagram of the utility model.Fig. 2 is the top view of Fig. 1.
Embodiment：
Embodiment：With reference to figure 1, Fig. 2, the two-sided cross bar steel grating of a kind of strengthen rigidity and intensity, band steel is arranged by spacing
Weld some cross tubes 3 in 1 upper surface, it is characterised in that weld some sheer poles 2 in the lower surface of band steel 1；Some cross tubes 3 with
Some sheer poles 2 formed up and down staggeredly it is evenly distributed；Hound 4 is set between adjacent cross tube and sheer pole.
