Device for forming a girder flange made of reinforced or prestressed concrete.

The invention relates to a formwork device for the lower flange of a Beam made of iron or prestressed concrete with multiple uses and adjustable dimensions. Said splash has about a KX

Cross
rectangular to quadrangular ^ .taEO & tschnitt and iat cast independently of the carrier core.

The known for the manufacture of such a flange formwork devices consist of formwork jaws and a mold base with articulated parts, 'the production of such a vertical enable upward or compliant bottom flange, _it the side parts are solidary with the bottom parts, usually by fixing screws. The bottom parts are therefore provided with several rows of connecting holes for the side parts and thus allow the production of carrier flanges of various widths. When producing a flange that does not have the smallest possible width, the connecting holes located between the side parts have to be blocked as a result.

To ensure continuity between the sides, each opening is between the side panels sealed by a wide side segment, which is made of a compressible material "and has the same vertical inner profile as this one

Side panels. This side segment is in prestressed or inserted in the pre-stretched state between these side parts.

According to a further feature of the new device, the sliding of the side parts (lurch. Screwing spindles accomplished that in .transverse direction- in the lower part of the opening located between the base parts and the corresponding side part ends, move with the help of slide rails. These screw spindles are preferably on both sides the formwork and along its entire length with the help of two synchronization devices matched to one another. These synchronizing devices - can also be synchronized among themselves.

The new device gives the possibility to work with the bottom parts and the side parts

in this case xxi carried by two bottom parts each, one by pairs of winches that move vertically and are grouped together in two groups. The first group is used by separate handling of the individual vV'inden to adjust the perpendicular polygonal shape of the formwork; the second (J-group causes the release or replacement of the whole formwork by a synchronized action on all winches, without changing its aforementioned polygonal shape. The winches opposite each other in the first group are preferably operated synchronously «

The so.halungsstu.tsen, especially the above-, so-called winch pairs », are advantageous on drives installed “the one longitudinal shift of the entire formwork enable> without necessarily its vertical polygonal

This protruding handrail 57 is further reinforced by a U-iron 56, the height of which, incidentally, corresponds to the windest height of the formwork to be produced.

Each concrete prism 56 has a half-open profile iron 59 attached to its lower outer edge, which creates a downwardly open longitudinal channel.
