<p>A device for application of formwork in concreting horizontal and sloping edgings and ties with safety fence is solving the problem of formwork when placing concrete for slabs and at the same time the problem of safe work due to its integrated fence. According to the invention, a formwork bearing assembly (1) is mounted on the exterior side of a wall (5) by means of a screw (22) and three plate nuts (21). A wall prop (3) and a wall-formwork prop (3') are pressed and fixed to the wall (5). A formwork board (26) is attached by means of the wall-formwork prop (3') with the help of a movable support (18) fixable with a wing head screw (16). The formwork board (26) is pressed against a formwork prop (4) and fixed by means of a small plate (14). The wall prop (3), wall-formwork prop (3') and formwork prop (4) can be adjusted along the length and the height of a holder (6). They are adjustable in length by means of an extractable tube (8) inserted into a tube (9), the length of motion being limited by a motion stopper (11). They are also adjustable in height by means of embracing tubes (7) loosely mounted on the holder (6), where they can be moved and fixed with wing head screws (16) in a position selected. A tube (23) wearing a fence assembly (2) with two mounted fence boards (25) is inserted and attached into the holder (6).</p> |
