Description
Technical field
The utility model relates to technical field of floor, and especially a kind of steel is net floor on an empty stomach.
Background technology
Existing steel net floor on an empty stomach generally is made up of component such as floor, cover plates, and the floor then is made up of panel, base plate.This composition or employing welded construction, or adopt on base plate, to make to push up and box out, the hole flanging riveted joint formed behind the panel piercing and flanging.Outlet be by with the cover plate of floor assembling on line outlet realize.
The net floor of existing structure, at first connect and have certain defective in the combination of panel, base plate: the one, welded construction, the weakness that exists thermal deformation to overcome, the flatness after the combination be cannot say for sure to demonstrate,prove, and welding procedure has limited the use that has the coated layer material to the destruction on surface.The 2nd, the piercing and flanging riveted structure because always there are certain interval in pre-manufactured hole and flange projection, can't be avoided the weakness of riveting intensity poor reliability, especially shows dynamic loading.Secondly, on the composition of net floor, the existence of cover plate has increased component parts quantity, has improved manufacturing cost on the one hand, has increased the construction and installation workload on the other hand.Owing to be not fixedly connected between cover plate and floor, cause the whole net floor stability of a system poor simultaneously.
The utility model content
The purpose of this utility model is the defective that overcomes prior art, and a kind of steel net floor on an empty stomach is provided, and its manufacturing process is simple, and is easy for installation, with low cost, but suitability for industrialized production.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of steel is net floor on an empty stomach, comprises panel, base plate, and its faceplate perimeter is provided with lock seaming and breach, and breach is the cabling mouth;
Base plate is periphery flanged box-like that makes progress, be converted into level table outside the top of periphery flange, box-like base plate bottom surface is provided with most round aecidioids or most kidney shape cup-shaped boss upwards, the level table of the end face of these boss and base plate flange is in same plane, in the level table outer of four limit flanges, have and the corresponding breach of the breach on the every limit of panel;
The level table outer of base plate and the lock seaming of faceplate perimeter are suitable;
The end face of base plate boss and the level table of flange and panel soffit be the company of subsides closely, and the tight subsides company headquarters position at panel and base plate is provided with connection part, and connection part is affixed with panel and base plate.
Described steel is net floor on an empty stomach, and its described connection part comprises projection and groove, and projection is positioned at the panel soffit, protrudes out downwards, and there is the ring of inlaying on the projection top, and groove is positioned on the level table of the end face of base plate boss and flange; Projection and groove are suitable, and inlaying of projection encircles the bottom surface periphery that is positioned at groove.
Described steel is net floor on an empty stomach, and its described connection part is most; At the connection part at the level table place of base plate flange, the spacing between two is not more than 70 millimeters.
Described steel is net floor on an empty stomach, and the thickness of its described panel is greater than the thickness of base plate.
Described steel is net floor on an empty stomach, and its described breach has at least two small gaps on the every limit of panel, wherein goes up on one side to also have at least one big breach, and large and small breach is the cabling mouth.
Described steel is net floor on an empty stomach, and it is described in the level table outer of base plate four limit flanges, has and the corresponding breach of the breach on the every limit of panel, is and the corresponding breach of large and small breach.
Steel plate is made panel and base plate respectively through punching press distortion, on the limit of panel and base plate, makes line outlet, at the position that panel and base plate need connect, adopts the cold-pressing deformation draw bail, adopts the lock seaming structure around the floor.
The utility model owing to adopt cold-pressing deformation to connect, has overcome thermal deformation weakness that welded construction exists and to the surface breakdown of coated layer material.Connect because this connection is a kind of no gap, so the intensity of interface has had large increase than the piercing and flanging riveted joint, especially dynamic loading intensity is more remarkable.Because line outlet is arranged on the floor body, amount of parts significantly reduces, and has promptly reduced product cost, has reduced again by the dress expense.The lock seaming structure at line outlet place also can be protected cable effectively.
Description of drawings
Fig. 1 is the utility model upper plane schematic diagram.
Fig. 2 is the A-A generalized section among Fig. 1.
Fig. 3 is 5,6 place's partial enlarged drawings among Fig. 2.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, panel 3 peripheries are bent downwardly out flange boxing spare, and two small gaps 1 are made on every limit on four limits, make a big breach 2 on one of them limit again, and small gap 1 and big breach 2 all are the cabling mouth.Base plate 4 is drawn into periphery flanged box-like that makes progress, be converted into level table outside the top of periphery flange, most round aecidioids or most kidney shape cup-shaped boss are upwards made in box-like base plate 4 bottom surfaces, the level table of the end face of these boss and base plate 4 flanges is in same plane, in the level table outer of four limit flanges, have and the corresponding large and small breach of the breach on panel 3 every limits.The thickness of panel 3 is greater than the thickness of base plate 4.The end face of the boss of base plate 4 and the level table of flange are the effective points of attachment with panel 3 soffits.Box part panel 3 is anchored on the base plate 4,6 places on the level table of the end face position 5 of the boss of base plate 4 and flange, from panel 3 tops, exert pressure through mould counter plate 3, base plate 4, make the extruding point produce distortion, form pit, under the continuous effect of extruding, the pit bottom material constantly is out of shape, and flows to the side of pit, ring 7 is inlayed in formation, thereby forms no gap cold-pressing deformation connection part.Be not more than 70mm between the level table place connection part of flange at interval.After the periphery lock seaming 8, net floor promptly joins together.
