J13684022

The invention relates to the construction - sheet curvature 500 mm, width

It can also be used for equipping industrial buildings and civil structures, as well as ships and aircraft, and belongs to the folded sheets of a curvilinear profile.

The purpose of the invention is to increase the rigidity and simplify the manufacturing technology, as well as to simplify the joining of sheets and the production of sheets of a complex profile.

Figure 1 shows a folded sheet.

general form; figure 2 - the same, transverse from flat steel sheet

ny profile; on fig.Z - a sheet with connecting and transitional sections from flat quadrangular plates; in Fig „4 -, the same, with connecting and transitional sections, transverse: profiles.

; The curved sheet of the curvilinear, the outline consists of zigzag: tape rows 1, containing the combined along the contour at an angle to one,: the other quadrangular plates 2: the forms of a single-leaf hyperbolic paraboloid with pairwise equal opposite edges 3 and 4. The folding profile of the folded sheet is echer -30 stiffness and simplification of the technology of convex broken concentric manufacturing, anti-ice kim 5 and 6. The folded sheet of the edges of the plates are equal in pairs, and filled with connecting and transitional and sections 7 and 8, made of zigzag ribbons from flat. quadrangular plates 9 and 10, having the form of a trapezoid or parallelogram; ma. The sheet is made of flat blanks | KI.

Example. A folded 40 nano with a flat edge plate was made of steel 20 with a thickness of 1.0 mm of a rectangular shape.

sheet 170 mm, relief height 10 mm. The sides of the hyperbolic plates are 20 and 30 mm long. In press

the plates were given a given hyperbolic shape. Sheets and panels are joined by welding or on rivets with overlapping and connecting sections. Folded panels can be made with cold or insulated skins.

A folded sheet can be made with a small thickness by cold bending. as well as from plastic, hardboard, fiberglass plastics in a hot way

20 Forms of Invention

1. A folded sheet with a curvilinear outline made of a flat blank and including zigzag-like shapes. Ribbon rows of rectangular plates combined along a contour at an angle to one another to form saw-like folds.

This is because, with a view to, the surface of each plate is in the form of a single-loop hyperbolic paraboloid.

2. Sheet POP.1, characterized in that, in order to simplify the joining of the sheets and to obtain sheets of a complex profile, the sheet is made

Claims (2)

1. A folded sheet of curved shape, made of a flat blank and including zigzag ribbon rows of plates joined at an angle to one another from sawtooth folds, which are rectangular in shape to form a welt In order to increase rigidity and simplify manufacturing technology, the opposite edges of the plates are pairwise equal, and the surface of each plate has the shape of a single-leaf hyperbolic paraboloid. 2. The sheet according to claim 1, characterized in that, in order to simplify the connection of the sheets and obtain sheets with a complex profile, the sheet is made with flat edge plates of a quadrangular shape.
