An overall convex stretch stamping grille

Abstract

An integral raised stretch stamping grille, including a longitudinal pedal and a transverse sealing plate, the longitudinal tread is made by integral raised stretching stamping process, the two sides of the longitudinal tread are welded with transverse sealing plates, wherein the longitudinal tread is composed of multiple It is composed of strip-shaped raised blocks arranged at a certain distance and with a rectangular cross-section. It is characterized by the gap left between two adjacent strip-shaped raised blocks. 'The protruding block is connected through the connecting plate at the bottom of the protruding block, so that a plurality of strip-shaped protruding blocks in the vertical direction of the pedal are connected together to form a whole, which can increase the overall strength of the grid and reduce the longitudinal vacant area, preventing Pedestrian sprains. The present invention adopts the overall protrusion stretching stamping forming process, so that the longitudinal pedal of the grille does not need to be welded into one body, and has the advantages of light structure, beautiful appearance, strong load capacity, convenient installation, strong anti-corrosion, and low price, and is especially suitable for use in ships. and marine engineering.

Description

Technical field: [0001] The invention relates to a grid, in particular to an integrally raised stretched stamping grid for ships and ocean engineering, and is an application for a patent for invention with the publication number CN101363571A "Integral raised stretched stamping grid" The improvement of the structure belongs to the manufacturing technology of the grid. Background technique: [0002] At present, most of the grids used in ships and marine engineering are still traditional steel grid plates, that is, in the manufacturing structure of the main bearing surface of the grid, 4-5mm flat steel strips are interweaved and welded together. To ensure the load-bearing strength, its main load-bearing surface is a plane, which is neither beautiful nor non-slip. The severe weather will make the traditional steel grating seriously corroded, and there are unsafe factors; there are also molded gratings, which are a kind of glass steel plate with many regular rectangular spaces. ...

[0002] At present, most of the grids used in ships and marine engineering are still traditional steel grid plates, that is, in the manufacturing structure of the main bearing surface of the grid, 4-5mm flat steel strips are interweaved and welded together. To ensure the load-bearing strength, its main load-bearing surface is a plane, which is neither beautiful nor non-slip. The harsh climate will cause serious corrosion of traditional steel gratings, and there are unsafe factors; there are also molded gratings, which are glass steel plates with many regular rectangular spaces. The fire will release harmful poisonous smoke, hindering the escape of people
