Safe grid plate without continuous frames

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 [0001] The invention relates to a building component, in particular to a safety-type grid plate without continuous frame borders, which has simple structure, convenient processing, reliable operation, safety and beautiful appearance. Background technique [0002] Grid plate is a high-strength load-bearing cover plate with a large amount of matching in building construction. It is widely used in construction platforms, Walkways, trestles, ditch covers, manhole covers, steps or steps have the functions of anti-slip, ventilation, lighting, heat dissipation, explosion-proof, anti-accumulation of dirt or water, and the function of carrying equipment or passing vehicles and pedestrians. There are many kinds of metal or non-metal gratings commonly used at present, all of which are composed of the surrounding frame and the middle working surface with grid bars and grid holes on it, and most of them are casted, die-casted or formed by metal or non-metal It is made of...

AI Technical Summary

Problems solved by technology

There are many kinds of metal or non-metal gratings commonly used at present, all of which are composed of the surrounding frame and the middle working surface with grid bars and grid holes on it, and most of them are casted, die-casted or formed by metal or non-metal It is made of punching holes on the metal plate, which is common: the product manufacturing process is complicated, the processing cost is high; There are closed transfer gaps, and garbage or pollutants are easy to accumulate in the transfer gaps during use, resulting in poor drainage of dripping water on the ground and easy to cause unsafe conditions of vehicles and pedestrians slipping

Therefore, there is an unreasonable structure on the whole, and it is not ideal from the perspective of economy and practicality.
