Abstract
The invention relates to a safe grid plate without continuous frames. The mainbody of the safe grid plate takes the shape of a coiling-type flat plate without continuous frames and is composed of: grid bars, i.e., comparatively long straight bars formed by continuously reversely bending bar-shaped flat plates; bending parts at the center of the ends of the comparatively long straight bars; and grid holes, i.e., clearances among the grid bars. The thickness of the grid plate complies with the width of the bar-shaped flat plate; the bending part can take a semicircular bending shape, an acute angle bending shape or a vertical bending shape; the facade, the middle part or the back surface of the grid plate can be provided with a stiffener or a net plate according to the requirement so as to meet the requirements of bearing reliability and resisting the article loss for the grid plates with comparatively large area or comparatively long span; and when in use, the bending part and a foundation installation frame hole edge form a point contact state or an extremely short line contact state, thus overcoming the unsafe condition that the flowing water on the ground surface is not smooth tobe gathered or drained and the passerby or vehicle slides when moving on the ground surface as the garbage or contamination is easy to be accumulated on the junction or surface between the grid plateand the foundation installation frame hole edge in the prior art, thereby being beneficial for ensuring the safe production and environmental sanitation and having extremely practicability.
Description
Technical field
The present invention relates to a kind of building unit, particularly a kind of safe grid plate with no continuous frames of simple in structure, easy to process, reliable operation and safety and good looking appearance.
Background technology
Flase floor be a kind of in building operations the high strength carrying cover plate of supporting large usage quantity, on being widely used in construction platform, aisle, trestle, operculum colpi, well lid, the step of industries such as petrochemical industry, mechanical metallurgy, food processing, chemical fertilizer pharmacy, agriculture and animal husbandry wooden land and municipal engineering or marking time, have anti-skidding, ventilation, daylighting, heat radiation, explosion-proof, anti-contamination thing or drop down the effect of water and load bearing equipment or vehicular traffic pedestrian's function.The metal commonly used at present or the flase floor of non-metallic material have varied, by frame on every side and above be provided with middle the work plane formation in grizzly bar and grid hole, and make ubiquity by metal or nonmetal casting, die cast or by punching on metal sheet mostly: production complex process, processing cost height; Materials are many, installation is provided with cumbersome; Frame setting on every side is continuous enclosed, between installment state Under The Grille plate and basic installing frame, there is closed handing-over slit, handing-over slit place gathers rubbish or pollutant easily during use, causing ground to drop down water, to converge row not smooth, causes the dangerous situation that vehicle and pedestrian are skidded easily.Thereby exist structure to owe rationally generally, consider all to owe desirable weak point from economy and point of view of practicability.
Summary of the invention
The objective of the invention is to overcome the existing existing weak point of closed frame flase floor of being with, provide a kind of simple in structure and reasonable, easy to make and materials are economized, easy for installation and that cost is set is low, can effectively avoid taking place ground and drop down water and converge the smooth and surface of row and gather rubbish, cause the skid safe grid plate of no continuous frames of situation of vehicle and pedestrian.
The safe grid plate main body of no continuous frames of the present invention is the flat bulk, include the middle work plane that constitutes by grizzly bar and grid hole and edge on every side, it is characterized in that described middle work plane is " coiled ", oppositely bending longer vertical bar that constitutes and the kink that is positioned between longer vertical bar end continuously by the strip flat sheet constitutes, edge is discontinuous formula around described, and wherein: described grizzly bar is filled the post of by described longer vertical bar; Described grid hole is filled the post of by the gap that is positioned between described longer vertical bar; The thickness of the block flase floor of described flat conforms to the width of described strip flat sheet; Described kink can be provided with and be semicircle bending, wedge angle bending or vertical bending.
In addition, on front, centre or the back side of the block flase floor of described flat, can also increase as required reinforcing rib or web plate are set, with the load-bearing of satisfying the big or longer flase floor of span of area and the requirement that stops the related item loss; Described strip flat sheet both can be filled the post of by the flat sheet material that width satisfies the flase floor thickness requirement, also can be filled the post of by the corrugated sheet material that width satisfies the flase floor thickness requirement; Described strip flat sheet can be made by metal material or nonmetals.
Under the installment state in use, the safe grid plate of no continuous frames of the present invention is inlayed on the basic installing frame or aperture convex shoulder that is arranged on building, is between described kink and basic installing frame or the edge, aperture to contact or an extremely short line contact condition.
The safe grid plate that does not have continuous frames based on the present invention of above-mentioned design, because oppositely bending grizzly bar with certain thickness and spacing that constitutes and the kink that is positioned between the grizzly bar end continuously by the strip flat sheet with certain width, the flase floor main body constitutes, there is not continuous frames on every side, under the installment state in use, be between described kink and basic installing frame or the edge, aperture and contact or an extremely short line contact condition, outside decapacitation guarantees that the bearing strength in satisfied the use requires, pollutant or ground trickling water flows in trench or the sewer unblockedly in the time of can also guaranteeing work, can effectively avoid taking place gathering rubbish or pollutant easily on the junction, edge of flase floor and basic installing frame mouth in the prior art or the surface, it is smooth and cause the unsafe conditions that pedestrian or vehicle skid when the last walking to cause trickling water in ground to converge row, help ensuring safety in production and sanitation of environment, compare with existing like product, obviously has scientific structure and reasonable, easy to process and materials are few, easy to use and that cost is set is low, reliable operation and high safety, plurality of advantages such as good looking appearance and work are widely applicable, thereby have remarkable economical and very strong practicality.
