Description

The invention relates to formwork used to erect a building in several Concreting sections are gradually adjustable in height, comprising several Formwork elements, which together form the formwork skin, a respective Formwork element several arranged one above the other in the vertical direction and includes interconnectable parts, each across the width extend the formwork element.

Formwork used to erect a structure in several concreting sections are gradually adjustable in height and include several formwork elements, are known in the form of different types of climbing formwork. For example are climbing formwork in connection with the erection of circular structures known in which two circumferentially closed formwork rings be suspended from a supporting structure. The one delimited by the formwork rings Formwork cavity is filled with concrete after the hardening or setting of the The formwork rings are loosened in concrete and raised on the supporting structure until that its lower part is still in the area of the upper edge of the cast wall ring lies. Then the rings are clamped and fixed again, concrete filled in again and the aforementioned interplay repeats itself until the desired one Height is reached. In this way, such cylindrical Build a wall ring on top of the other.

Another type of climbing formwork is, for example, in US Pat. No. 1,478,653 shown and described. The essence of such climbing formwork is that formwork anchors penetrating the masonry must be provided and with which the formwork elements are braced in their entirety, the anchors concreted in at the top during a concreting step in the sequence can be used as foot anchors for the formwork in the next concreting step. A new anchor is then installed in each concreting step. The formwork will then raised when the previous concrete section of the wall has set has the entire weight of the formwork over the formwork anchors has to carry. The formwork itself consists of the actual formwork panels and the scaffold stiffening the formwork panels.

DE 12 66 948 B shows climbing formwork with the formwork rings during concreting are connected by spacers. A scaffolding bell reaches with its lower part under the lower edge of the outer formwork ring and is placed on rigid brackets that can be detached via the profile rails are attached to the already hardened part of the structure. To pull up the Formwork rings are attached to the upper end of the scaffolding bell. On The consoles have a work platform underneath the formwork. After concreting a section, the formwork rings are loosened and raised by means of pull winches attached to the scaffolding bell. Thereupon will the lower section of the profile rails is placed on the upper section and then the scaffolding bell is lifted on the winches attached to the formwork rings and attached to the profile rails via the brackets

EP 471 870 A1 shows a formwork with several ones arranged one above the other Formwork panels and a yoke frame. The yoke frame, which is lifted is adjustable in height on a climbing pole, the inclusion of the shear forces occurring when pouring the concrete safely. This happens through a cross anchor, which is attached over the top of the formwork. Is also a work platform located at the level of the cross anchor on this yoke frame attached. In the process, after the concrete has solidified, the The cross anchor was released and the yoke scaffold raised upwards. Then the the bottom formwork panel is placed over the top one and after the application of the The next section of the Concrete concreted. The ones shown in EP 471 870 A1 are arranged one above the other and formwork panels that can be connected to each other can be divided into several parts Formwork elements are viewed in (being in the circumferential direction of the building several such formwork elements are present), so this formwork is a formwork of the type mentioned.

The object of the invention is to improve the formwork of the aforementioned Provide kind that also a particularly advantageous workflow at the Construction of the building possible. According to the invention, this is achieved by a Formwork with the features of claim 1.

By forming a respective formwork element with the main part and the two can optionally be set at the top and bottom of the main part Climbing parts, the formwork can be easily raised, as will be explained in more detail in the description of the figures. By the at The stiffening units attached to the climbing parts are very good overall rigid formwork element provided. Form these stiffening units work platforms that can be walked on at the same time, so that separately provided work platforms can be saved.

The stiffening unit advantageously has at least one in one at least essentially horizontal plane, at least above a large part of the width of the climbing part extending flat stiffening element on. The specification "essentially horizontal" is intended to have a range of +/- 20 ° compared to the horizontal.

A formwork according to the invention is particularly suitable for producing a curved, optionally circumferentially closed wall, an inventive Formwork but also in connection with the production of a flat wall can be used.

A formwork according to the invention can advantageously be placed on a respective Side of the wall to be created with a single row of side by side adjacent and across the width of the wall or - in the case of a circumferentially closed Wall - formwork elements running around the circumference of the wall, which each have a main body and with the top and bottom of the main part have alternately connectable climbing parts, enough Find.

That shown in Fig. 1 in a perspective view and somewhat simplified Formwork element of a formwork according to the invention is formed in several parts with a main part 1 and at the upper and lower edge 2, 3 of the main part 1 this adjacent climbing parts 4, which are detachably connected to the main part 1. The climbing parts 4, which each extend over the entire width of the main part 1, are identical and can optionally be adjacent to each other the upper edge 2 or adjacent to the lower edge 3 of the main part 1 be attached to this. These fasteners - explained in more detail later - which are not shown in detail in Fig. 1, can in different Be trained.

The main part 1 and the climbing parts 4 each form sections 5, 6 of the total formwork skin designated by the reference numeral 7, or in other words, point formwork panels each, which form part of the formwork surface 8 (see, for example, FIG. 2) form. These sections 5, 6 of the formlining 7 can each be made of suitable metal sheets be formed.

On the back of the formlining 7 opposite the formwork surface 8 are both vertical for both the main part 1 and the climbing parts 4 running and extending over the height of parts 1, 4 rails 9, 10, 11, 12 attached. Across the width of the main part 1 or climbing part 4 are at least three, preferably more than three, of each other spaced rails 9 to 12 provided. In the embodiment shown are the profile rails lying in a central region of parts 1, 4 9, 11 Z-shaped and the edge-side rails 10, 12 are U-shaped, with their open sides facing each other are. The rails 11, 12 of the climbing parts 4 set the rails 9, 10 of the main part 1 in a straight line, thus in alignment with them.

On the side of the profile rails 9 to 12 facing away from the formlining 7 at least one for both the main part 1 and the climbing parts 4 horizontally extending and at least attached to the middle rails 9, 11 Stiffening rail 13 is provided. The climbing parts 4 each have one individual such stiffening rail 13 and the main part 1 is with two in Stiffening rails 13 spaced apart from one another in the vertical direction. These stiffening rails 13, which are double-U-shaped in the exemplary embodiment shown Profiles formed with base legs facing each other are the curvature of the formwork element in the horizontal direction.

To allow changes in the curvature of the stiffening rails 13 these preferably do not reach all the way to the edge of the formwork element. Their end areas can rest on the profile rails 10, 12 or with them be screwed, the screw points, for example, by in the Stiffening rails 13 provided extending in the horizontal direction Elongated holes can be changed. There can also be fasteners between the stiffening rails 13 of two adjacent formwork elements be provided, as is exemplified in FIGS. 17 and 18. As Connecting elements here are two steel tabs 45, which on the sides of the spaced apart webs facing away from each other of the U-profiles of the double-U-shaped stiffening rails 13 abut and clamped with the stiffening rails 13 by clamping screws 46 become.

On the climbing parts 4 there is a cantilever from the rear of the climbing part and with the climbing part 4 in rigid connection stiffening unit 14 set. In the exemplary embodiment shown there are from the rear of a respective climbing part 4 horizontal support beams 15 from which to the the facing 7 facing sides of the rails 11 are attached and the of obliquely upward support beams 16, which are also on the rails 11 are fixed, are supported in the region of their free ends. On the support beam 15 is a truss-like lying in a horizontal plane trained frame. This rigid framework is at least two attachment points with the support beam 15 connected immovably. Preferably, there are at least two such attachment points for each support beam 15 provided and furthermore preferably at least three over the width of the climbing part 4 arranged such supporting beams 15 are provided. This frame connected to the support beam 15 thus forms a flat Stiffening element 17, which is in a rigid connection with the climbing part 4 stands.

The stiffening unit 14 also has one of the frame-shaped stiffening element 17 worn flooring, for example of that shown in Fig. 3 Boards 18 is formed. Furthermore, to secure people, who commit this stiffening unit 14 designed as a working platform, yet A railing on the edge of the stiffening element facing away from the formlining 7 44 attached, as this is shown schematically in FIGS. 4 to 8.

The fasteners of the rails 9, 10, 11 and 12 on the back of the Formwork skin, the stiffening rails 13 on the profile rails 9 to 12, the Tragund Support beams on the profile rails 11 and the stiffening elements 17 on the Support beams 16 are not shown in detail in FIG. 1. These can be done in conventional Form of screw connections, rivets or the like. Are formed. At least the fastenings of the stiffening rails are preferred 13 on the profile rails 9 to 12 and the stiffening elements 17 on the support beams 15 detachable. The curvature of the formwork element can then be changed be by removing the stiffening rails 13 and on a Rounding machine can be changed in its curvature and subsequently in turn be connected to the rails 9 to 12. Afterwards you can the stiffening elements 17 are in turn connected to the supporting beams 15 corresponding changed connection points).

The individual formwork elements that are laterally adjacent to one another can, for example in a conventional manner with appropriate clamping devices be connected. Advantageously, an inventive Formwork only one on each side of the wall to be created Have a number of such formwork elements which laterally adjoin one another, after the production of a concreting section of the Wall to be moved up to the next concreting section formed accordingly.

The movement of a formwork according to the invention is shown below explained with reference to FIGS. 4 to 8. Fig. 4 shows the construction phase in which a switch Concreting section 19 has been completed and has already hardened sufficiently. It are now the connecting means between the main part 1 and the upper edge of the main part 1 attached climbing part 4 opened. As a result the main part 1 by means of the climbing part 4 fastened to the lower edge thereof of a lifting device 20 shown schematically in FIG. 5 removed from the wall become. For this purpose, the anchorages between the lower part of the climbing 4 and the wall and, if necessary, the anchorages between the Main part 1 and the wall solved. As a result, the connecting means between the main part 1 and the climbing part 4 attached to its lower edge opened and the climbing part 4 is removed from the lower edge of the main part and attached to the top of the main body and adjacent to the top Edge 2 of the main part 1 connected to the main part (see FIG. 6). Instead of this described work order, it would also be possible to open the Connection between the main part and the climbing part attached to the upper edge 4 the connection between the main part and the one attached to the bottom Climbing part 4 to open and first climbing part 4 from the wall and from the main part 1 and subsequently the main part 1 from the upper climbing part 4 and from to remove the wall.

On the climbing part 4 remaining on the finished concreting section 19 is in the consequence of the main part 1 with its lower edge, whereupon these two Parts are connected to one another by suitable connecting means (Fig. 7).

On both sides of the wall to be created is in the manner described method. The formwork elements arranged on both sides of the wall are subsequently shown by means of anchorages shown schematically in FIG 21 connected as is conventionally known. Such sagging can be formed, for example, by threaded rods, which are plastic pipes push through so that the threaded rods come out of the finished concreting section 19 can be pulled out again.

To attach the climbing parts to the wall, be in the wall along their Expansion in several places in a known manner shown schematically in Fig. 8 Concrete formwork anchor 22, which is constructed in a conventional manner could be. These anchors can, for example, from the outside and inside internal wall accessible threads, in which bolts are screwed in, which carry the climbing parts 4.

By the horizontal with the formwork 7 in a rigid connection Bracing elements 17 become an effective bracing of each formwork element reached. This is important since the one already completed Concreting section 19 formwork elements defined this concreting section 19 protrude relatively far upwards, whereby when pouring concrete for Production of the next concreting section high pressure forces on the formwork elements be exercised. At the same time, they form the stiffening elements 17 having stiffening units 14 advantageously accessible work platforms. Due to the inventive design, the main part 1 can a comparatively lower bending stiffness.

For further stiffening, the stiffening elements 17 from neighboring ones Formwork elements in the area of their sides facing away from the formlining 7 be connected to each other.

Such a connection is shown schematically in FIG. The tab 48 out Flat steel with two holes that are pushed onto two bolts and with wedge or Splint is secured, connects the frame-like stiffening elements 17 and pressure-resistant. If the radius of the formwork element changes, one becomes different were inserted tab. For example, instead of a tab also a turnbuckle 49 can be used as a connecting element, as in 16 is shown schematically.

To connect a respective climbing part 4 with the main part 1 can be different trained connecting means may be provided. For example, 8 and 9, on the main part 1 in the area of its upper edge vertically aligned thick wall tube pieces 23 set his. On the climbing parts 4 are also in the area of their upper and lower edges at least two spaced thick wall tube pieces 24 are defined. in the the through openings of the Heavy wall pipe pieces 23 of the main part with those attached to the respective climbing part 4 Thick wall pipe pieces 24. As a result, the thick wall pipe pieces 23, 24 screwed together by means of bolts 25. To facilitate the mutual alignment between the main part 1 and the climbing part 4 can the thick wall pipe pieces 24 attached to one of the two parts conical projecting in the direction of the opposite thick wall tube piece 23 Projection and the opposite thick wall tube pieces 23 a corresponding Have deepening. Instead or in addition, others can Alignment means may be provided. For example, the main part 1 could over whose upper edge protrudes and protrudes obliquely upwards from this Sheet metal parts can be arranged, which form inlet slopes for the climbing parts. Instead of the thick wall pipe pieces described, other connecting means could also be used be used between parts 1, 4, for example with holes provided plates that are connected to each other by means of screw bolts.

A somewhat modified embodiment of the invention is shown in FIGS. 10 and 11 shown. A respective one formed as a frame lying in one plane flat stiffening element 17 is here via support brackets 26 with the profile rails 11 connected. Such a support bracket is shown in Fig. 13 and is from formed a folded sheet. The support bracket has a vertical web 27 on, the height of which decreases towards the free end of the support bracket. At the top and at the bottom of the vertical web are through bends horizontal flanges 28, 29 provided. The horizontal flange 28 serves to support the stiffening element 17 and points for screwing to the Stiffening element 17 through openings. On its facing the profile rail 11 The vertical web has one end formed by a bevel Mounting flange 30, which in a vertical plane parallel to the Formwork skin 7 facing web of the profile rail 11 is located. The mounting flange 30 has through openings for screwing to the profile rail 11 on.

If the curvature of the formwork element should be changeable (by the Use of differently curved stiffening rails 13) can be used for Adapting to the different curvatures the angles between the mounting flanges 30 and the vertical webs 27 of the support brackets 26 according to Art of a film hinge can be changed within a certain range, for example in the range of 90 ° +/- 15 °. Because the connection points between the top Horizontal flange 28 and the stiffening element 17 in the case of different Curvatures of the formwork element can at least partially change, for example 17 mounting plates 31 may be provided on the stiffening element to enable the connection points to be changed at least in part Have passage openings 32 in the form of elongated holes. By means of the passage openings 32 in the mounting plates 31 and the passage openings in Horizontal flange 28 penetrating screw connections, the connection be produced between the stiffening element 17 and the support brackets 26. Again, at least three are preferably in a horizontal direction from one another spaced support brackets 26 are provided. Overall, is ready to use Condition of the climbing part 4 a rigid connection between the horizontal stiffening element 17 of the stiffening unit 14 and the Formwork skin 7 or the profiled rails 11, 12 and which support the formwork skin 7 Stiffening rails 13 made. To complete the shown in Fig. 10 Climbing parts 4 are still walkable floor coverings on the stiffening elements 17 applied and railing 44 attached.

Another embodiment of the invention is shown in FIG. Be here in an analogous manner to the previously described embodiment Profile rails 11 fixed support brackets 26 used, which in turn as in 13 can be formed. Instead of a frame-shaped bracing element 17 a plate-shaped stiffening element 17 is used here, which can be formed, for example, in the form of a sheet metal plate (if appropriate with a non-slip coating or pad on the top). This horizontally lying, flat stiffening element 17 forms in this embodiment at the same time the floor covering of the accessible work platform.

14 are in the range the side edges of the formlining 7 of parts 1, 4 also Z-shaped rails 33 provided, the connecting web 35 of these rails with the side edge of the formwork skin 7 coincides and that is removed from the formwork skin horizontal web 34 protrudes beyond the side edge of the formlining. At the respective Side edge of the formlining 7 connects here to a wear piece 36 that is in the form of a vertically extending bar and, for example can consist of wood. The one facing the front of the formwork element Surface 37 is flush with the formwork surface 8 of the formwork skin 7 and thus also forms a section of the formwork surface 8. The wear pieces 36 are provided with suitable fastening means 38, for example nails the webs 34, 35 of the rails 33 connected.

By means of these wear pieces 36, the edge areas of the formwork skins 7 protected. In the event of wear or damage to the wearing parts 36 these wear pieces 36 can be replaced in a simple manner. Furthermore, can wear the pieces if they have some elasticity (such as Wood), the seal between two adjacent Improve formwork elements. Can also wear through these 36 minor adjustments to the circumstances (for example changes in wall thickness of the wall to be shuttered) can be achieved by using a wear piece with a suitable width, so that the total width of the Formwork element is somewhat changeable. To improve the seal between two formwork elements, the two wear pieces 36 in Cross-section can also be slightly conical, with their width from its surface 37 forming part of the formwork surface 8 to the opposite one Side reduced.

In Fig. 14 is also a possible clamping device for connecting two formwork elements that are laterally adjacent are shown schematically. This connecting device each has two superimposed ones horizontal clamping plates 39 (of which only the upper one in FIG. 14) is visible). A clamping bolt runs in the area between these clamping plates 40, the head 41 and the clamping nut 42 being larger in diameter than the vertical distance between the respective two clamping plates 39. in the Area of the end of the clamping plates 39 facing away from the formwork surface 8 is between the clamping plates 39 of a formwork element and the Clamping plates 39 of the other formwork element clamped a clamping piece 43. By the lever forces occurring when tightening the clamping nut 42 the formwork elements are firmly attached to each other in the area of the formwork surface 8 pressed so that a good seal between the two formwork elements is achieved.

A formwork according to the invention can be used for the outer formwork and / or the inner formwork of a building to be erected, the to formwork wall seen in the floor plan be curved or straight can.

Different modifications of the exemplary embodiments shown are conceivable and possible without leaving the scope of the invention. For example for the middle rails 9, 11 also U-shaped Profile rails or for all profile rails 9 to 12 T or I-shaped Profile rails can be provided.

To achieve good stiffening, it is advantageously provided that the Stiffening unit 14 in each case by one dimension in relation to the formlining 7 in the direction cantilever perpendicular to this, which at least 10%, preferably at least 15% of the total height of the formwork element. Preferably is the horizontal dimension of the flat bracing element 17 in Direction perpendicular to the formlining 7 at least 10%, preferably at least 15% of the total height of the formwork element.
