Definitions

the invention relates to formwork for the casting of building parts with two formwork walls delimiting a casting space, which has a plurality of adjoining formwork panels as well as support profiles that support them on the outer formwork surface.
Formwork of this type is offered, for example, by CH-PS 574 553 with formwork panels which are joined together with their angularly bent longitudinal edges and are fixed by wedges. These wedges engage in slots of perforated tabs of both formwork panels, which are arranged one above the other and, if necessary, pass through a double-perforated connecting tab.
the structure of this formwork is complicated and can only be used for certain purposes.
the inventor has set himself the goal of designing a formwork of the type mentioned at the outset in such a way that it can be used in as many different ways as possible and is easy to use, particularly with regard to the formwork's adaptability.
its stability should ensure safe concreting work.
the formwork which is essentially rectangular in plan, is variable in length in the installed position both in its vertical extent and in at least one horizontal direction.
two vertical support profiles in this installation position should be connected near their upper and lower ends by telescopically extendable ridge or transverse profiles to form a frame that is adjustable in height and stiffened by diagonal clamping elements.
This framework according to the invention takes into account the desire for optimal adaptability of the scaffolding dimensions to the respective building project and forms an essential part of the formwork scaffolding according to the invention.
the support profiles contain detachable support sections in the catch dimension or a multiple thereof and / or that the ridge profile has support sections and a T-beam connecting them to an end-mounted support piece.
the lower cross section is provided with axially interlocking tubular parts and extended by extension parts.
the ridge profile and / or the cross profile advantageously rests with end pins on the I-beams; these pins penetrate the inner flanges of the beams and are wedged against them.
This formwork according to the invention contains a ceiling shell in a manner known per se, since the side walls and ceiling of the building are to be cast simultaneously.
This ceiling shell rests on the one hand on the ridge profiles described, on the other hand on side profiles that run along the side walls of the formwork and rest on the I-beams.
the side profiles are connected to one another by corner pieces, which offer a wide contact surface for the ceiling shell and thus prevent any sagging in the corners.
the formwork panel is preferably provided with two swivel strips or swivel bolts, which are each articulated at a short distance from one of the side edges.
the distance to the side edge is dimensioned such that the pivoting strips can be pivoted in the installed position of the formwork panel over the flange of a vertical profile which is in contact with this and covers the impact caused by the adjacent side edges.
this vertical profile is provided with protruding locking pins which are received by locking recesses in the swivel strips and which then enable secure locking.
support profiles according to the invention are used, with two of these support profiles facing each other on both sides of the formwork and gripping vertically over the hollow profiles of the formwork panels.
These pairs of support profiles are each supplemented by - through the formwork - toggle bolts to form a ladder-like clamping part.
the I-beams form the base frame of the formwork and are at a relatively large distance from each other.
the support profiles hold the formwork panels at the two ends of their hollow profiles.
the vertical cover profiles are intended for closing the joints and locking the formwork panels, so they otherwise have no supporting function.
Protection is sought independently for arranging a lateral covering of the formwork, the core of which is formed by a clamping element which is placed on an outer flange of an I-beam and from which an articulated inclined support extends, which on the other hand or against an earth slope or the like. can be supported.
the clamping element has, as a clamping lock, two housing plates which overlap the outer flange on its side edges and in which one axially penetrating axle support which is fixedly connected at one end to a radial rotary lever is supported.
the housing plates are each provided with an internal cheek piece or the like. provided, which in the installed position abut the inner flange surfaces of the I-beam and which each have a movable clamping counterpart on the outer flange surface.
This is advantageously designed as an eccentrically mounted disc, which is firmly seated on that axle bolt and can be pressed onto the outer flange by its rotation or pulled away from the latter. So that a very simple and effective way of fastening the clamp lock is found.
the free end of the inclined support is equipped according to a further feature of the invention with a cross bolt, or the like at its two ends radial bores for receiving parts of an earth anchor. offers.
the side walls of a formwork 10 having a rectangular layout consist of an inner wall 11 and an outer wall 12 which is built at a distance a (from here about 20 cm), both of which are supported by external I-beams 14 which are vertical in the installed position.
Fig. 1 right, further length examples - with a support section 14 d of length i4 of 25 cm - are shown.
These carrier sections 14 a to 14 d are covered at the top by head plates 18 and at the bottom by foot plates 17, which according to the enlarged section of FIG. 1 of a front view of the I-beam 14 project laterally from the latter.
the long top support section 14 a has at its upper end in the installed position an inwardly projecting cantilever plate 18 a , to which an edge of a vertically extending corner plate 19 a is welded, this is at another edge with the inner flange 15 of the I-beam 14 connected.
a common ridge beam 22 which has a base piece from here two beam sections 14 c and a connection section 23 for a T-beam 24.
the latter is screwed at the other end to a support piece 25 at 26 and can be replaced to change the length of the ridge support 22.
the adjustable length is determined by a grid dimension n of 25 cm.
the lower ends of the pair of I-beams 14 which can be seen in FIG. 1 are connected by a telescopic tree 30 comprising two tube pieces 30 a , 30 b which can be axially displaced into one another with supplementary tube pieces 30 c .
This telescopic tree 30 and the end-end supplementary pipe section 30 c have an axial pin 31 which extends through the inner flange 15 of the I-beam 14 and which is penetrated in a manner not shown on the inside of the inner flange 15 by an adjusting wedge.
Reinforcing plates 32 are welded to the square tubes of the telescopic tree 30 illustrated in FIG. 3 at the points where holes 33 are provided for a connecting bolt, not shown.
FIG. 1 right side, above, an adjacent formwork with its inner wall 11 n , its ridge beam 22 and a side beam 28 is indicated.
the ceiling shell resting on the latter is designated by 36.
Fig. 1 with the reference numerals 11 ⁇ , 14 ⁇ , 30 ⁇ , 34 ⁇ is an embodiment in the grid and smaller in terms of height.
corner pieces 38 are provided between side beams 28 which are adjacent to one another at right angles, and an intermediate piece at 39 in the region of the future middle wall 40.
formwork 10 can also be changed in a horizontal dimension in its horizontal extent is indicated by the formwork stages 10 ⁇ , 10 ⁇ in FIG. 2.
a cast concrete wall 41 with a cast-on ceiling 41 a is still surrounded by the formwork 10; Inner wall 11 and outer wall 12 are connected by knurled bolts 27, each of which carries a pair of threaded sleeves 27 a .
both the inner wall 11 and the outer wall 12 are composed of individual formwork panels 44, each of which carries on its lower edge 45 a parallel hollow profile 46, which ent at 45 ent standing table overlap.
the vertical side edges of the formwork panels 44 in the installed position are covered by a vertical special profile 48 made of light metal I-shaped cross-section, with pivoting strips 51 of the formwork panel 44 overlapping the pressure flange 49 of the special profile 48 in the installed position.
FIG. 5 shows a further support profile 52, which is pressed on the outside against the hollow profiles 46 of the formwork panels 44 and is penetrated by those pin bolts 27.
the total height of the inner wall 11 and outer wall 12 can be changed by using different formwork panels; 4, 5 a shortened formwork panel 44 a of a height h 1 can be seen, this height h 1 corresponds to approximately one third of the height h of the other formwork panels 44.
Vertical struts or support profiles 52 of this type can be extended telescopically; a connection point in this respect is shown in FIG. 6 with two outer hollow profiles 54, each of which is provided on the outside with a cover plate 55.
a cross-sectionally I-shaped inner support 56 partially encompasses those hollow profiles 54 up to their cover plate 55.
the inner carrier 55 and the two outer hollow profiles 54 are penetrated by a bolt 58.
Fig. 7 shows a single formwork panel 44 with its hollow profile 46, which runs parallel to the lower edge 45 and overlaps it. Near the upper edge 43 is fixed by means of a screw 60 that swivel strip or latch 51 which, thanks to at least one washer strip 59, runs at a distance e from the formwork surface and has an edge recess 61 which in Installation position is pivoted via bolts, not shown, of the pressure flange 49.
FIG. 10 shows the principle of a lateral support of the formwork 10 against an inclined slope H.
the inner flange 15 and outer flange 16 of the I-beam 14 are shown exaggerated here for reasons of a better overview.
a clamping lock 66 is detachably connected to the outer flange 16.
a support profile 70 is pivotally connected by means of an axle bolt 68, which carries at its other end a holding pin 72 with two end bores 73.
the latter take up a U-bracket as an earth anchor, which is designated 74 in FIG. 10.
the length t of the support profile 70 here measures approximately 150 cm.
the clamping lock 66 has two outer housing plates 76, the inner distance of which corresponds to the flange width q, so that the outer flange 16 can be encompassed by the housing plates 76 connected by those axle bolts 68; Welded-on jaw webs 77 protrude from the inner sides of the housing plates 76 and serve as a stop for the outer flange 16.
Two circular disks 78 which are mounted eccentrically on that axle bolt 68, serve as the counter jaw, ie the disk center point M is a dimension y from the axis line A. of the axle pin 68 out ver puts.
