Abstract
The utility model discloses a novel n-shaped opened cold-rolled sectional steel, the section of the opened sectional steel is in an n-shaped structure, two ends of a side I in the middle are symmetrically and downward folded to form a side II and a side III, the other ends of the side II and the side III are outward bent, and the tail end of the outward bent part form a upward roll rim; the bearing capacity is great, and the performance is stable.
Description
Technical field
The utility model belongs to cold-rolled forming section technical field, especially relates to a kind of novel a few font open cold-forming sectional steels.
Background technology
At present, what steel work used as the skeleton in greenhouse is steel pipe, in the middle of this, there is common steel tube moulding rear surface to paint, also have and use hot galvanized steel pipe completely, and the object of Steel Pipe Design is being best aspect conveying fluid, but not being the proprietary material of building aspect, greenhouse the best, is that people there is no a kind of available substitute finding in the situation of special section bar in order to build greenhouse.In existing greenhouse structure system, the main section bar using or taking the C shaped steel of hot rolling, square steel pipe, round steel pipe as main, structure is single, supporting capacity is little, wastes raw material, and has increased the own wt of greenhouse bracket, and application life is short.
Summary of the invention
The purpose of this utility model is: provide that a kind of supporting capacity is large, novel a few font open cold-forming sectional steels of stable performance.
The technical solution of the utility model is: a kind of novel a few font open cold-forming sectional steels, for the opening shaped steel of steel plate cold bending formation, the cross section of opening shaped steel is several character form structures, the symmetrical folding downwards in I two ends, limit mediating has limit II and limit III, the outside bending of the other end of limit II and limit III, the end of outer dogleg section forms crimping upwards.
Further, outer dogleg section is flat bending, and the end of outer dogleg section forms straight line crimping upwards, and straight line crimping is parallel with limit III with limit II.
Further, outer dogleg section is arcuate structure, and the end of outer dogleg section forms arc crimping upwards.
Further, the height H of opening shaped steel is 40-200mm, and height of flange h is 10-150 mm, and breadth of section B is 15-200mm.
The beneficial effects of the utility model are: because the cross section of opening shaped steel is several character form structures, the symmetrical folding downwards in I two ends, limit mediating has limit II and limit III, the outside bending of the other end of limit II and limit III, the end of outer dogleg section forms crimping upwards, novel structure, supporting capacity is large, stable performance, yield strength >=235Mpa.Be applied in warmhouse booth, be better than life-span and the intensity of traditional steel, under equal supporting capacity, single-ridgepole glasshouse use steel use amount is the half left and right of traditional steel, has simplified whole warmhouse booth syndeton, can greatly reduce again the own wt of greenhouse support.The utility model is mainly applicable to the application scenario such as vegetables, flowers isothermal chamber booth.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another kind of embodiment of the present utility model.
Detailed description of the invention
Can find out from structural representation of the present utility model shown in Fig. 1, the utility model is the opening shaped steel that steel plate cold bending forms, the cross section of opening shaped steel is several character form structures, the limit I 1 two ends symmetry mediating is rolled over downward vertically and is had limit II 2 and limit III 3, the outside bending of the other end of limit II 2 and limit III 3, the end of outer dogleg section 5 forms crimping 4 upwards.Outer dogleg section 5 is flat bending, and the end of outer dogleg section forms straight line crimping 4 upwards, and straight line crimping 4 is parallel with limit III 3 with limit II 2.The height H of opening shaped steel is 40-200mm, and height of flange h is 10-150 mm, and breadth of section B is 15-200mm, and middle limit I width b is 10-100mm, yield strength >=235Mpa.
Fig. 2 is another kind of embodiment of the present utility model, and outer dogleg section 5 is arcuate structure, and the end of outer dogleg section 5 forms arc crimping 4 upwards.
Embodiment 1:
Outer dogleg section 5 is flat bending, the end of outer dogleg section 5 forms straight line crimping 4 upwards, straight line crimping 4 is parallel with limit III 3 with limit II 2, as shown in Figure 1, the height H of opening shaped steel is 104mm, and height of flange h is 22mm, breadth of section B is 118mm, middle limit I width b is 54mm, and wall thickness t is 4mm, yield strength 345Mpa.
Embodiment 2:
Outer dogleg section 5 is arcuate structure, and the end of outer dogleg section 5 forms arc crimping 4 upwards, as shown in Figure 2, the height H of opening shaped steel is 60mm, and height of flange h is 15mm, and breadth of section B is 80mm, the limit I width b of cold centre is 40mm, and wall thickness t is 5mm, yield strength 355Mpa.
The utility model novel structure, supporting capacity is large, and stable performance, while being applied in warmhouse booth: 1, greatly improve the performance in greenhouse, fill up the blank of warmhouse booth application cold-rolled forming section product; 2, dead load is light, greatly reduces the steel using amount of Keelof green house; 3, cold-rolled forming section being designed to specific a few font material can make dew inflow both sides on film bend up the rear suitable skeleton outflow of part, outstanding " dripping line " of cashing as forming along skeleton in former greenhouse do not had, well solve greenhouse dewfall water droplet problem, can be good at meeting greenhouse and use function; 4, energy-conservation, save land, environmental protection, steel can be recycled, in work progress, noise is little, dust is few, building waste is few, low in the pollution of the environment; 5, the Greenhouse Construction time fast, can produce in factory, on-site consolidation, climate impact is little, speed of application is fast, quality easily ensures.
