The straight flange aluminium sheet that is used for interior wall combination aluminium sheet die sinking punching press construction
Technical field
The utility model relates to the straight flange aluminium sheet, and the utility model relates in particular to the straight flange aluminium sheet for interior wall combination aluminium sheet die sinking punching press construction.
Background technology
It is very general that aluminium sheet is used for the Building decorating and repairs engineering inner wall decoration, and the aluminium sheet that uses at present is all round and smooth angle at dull and stereotyped flanging place, and the corner angle that can not reach dull and stereotyped flanging place that design proposes, protruding plate see that rib sees the effect of line; It is 10-15mm glue-line or close joint that the combination aluminium sheet is installed common joint gap, the joint gap error requirements is controlled at 1mm, when aluminium sheet installation joint gap is the 2mm stowing, the joint gap allowable error requires to be controlled at 0.5mm, the aluminium sheet machining accuracy that adopts does not at present reach requirement, therefore have certain problem on the joint gap error is controlled.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and reach the angular effect in edges and corners of projecting plate by the aluminium sheet flanging of slotting, and can guarantee the straight flange aluminium sheet that is used for interior wall combination aluminium sheet die sinking punching press construction of duration of a project, quality and decorative effect.
The technical scheme that the utility model is dealt with problems is:
Straight flange aluminium sheet for interior wall combination aluminium sheet die sinking punching press construction of the present utility model, longitudinally, laterally have cannelure and transverse groove in the every side of straight flange aluminium sheet surrounding, the longitudinal section of described cannelure and transverse groove is isosceles triangle, the thickness of described straight flange aluminium sheet with vertically, the difference of the groove depth of transverse groove is 0.7mm-0.9mm, described vertically, groove depth and the width error of transverse groove be not more than 0.1mm; The every side of straight flange aluminium sheet is positioned at vertically, transverse groove Outboard Sections arrange formation flanging vertical with the plate external surface, the length of described flanging less than respective side vertically, the length of transverse groove.
Compared with prior art, the utlity model has following remarkable advantage: the corner angle of having realized aluminium sheet flanging place, projecting plate see that rib sees the effect of line, have overcome the difficult problem at round and smooth angle, aluminium sheet flanging place, have solved construction obstacle, have reached design effect.
