Description

ACROW-WOLFF GmbH. Jägerhofstrasse 20 Formwork arrangement *

For structures of greater height such as towers, silos, chimneys and the like, it is common to use climbing formwork. Climbing formwork of this type can be implemented in the form of relocating formwork with two or three sections lying one above the other. Each section is there for itself anchored in the concrete, and when moving the bottom section is loosened and lifted with a construction crane or the like and placed on the top formwork, which is still anchored in the concrete.

Another type of climbing formwork has to projecting below Schalungtfvertikalen which are for anchoring herangezo _o en. In this case, a height corresponding to the climbing height is required. The overhang of the anchor vertical is twice to three times the height of the eye. When climbing this formwork, the entire formwork is loosened from the anchors, then lifted with a construction crane or the like and newly fixed in the area of the cantilevered formwork vertices on the existing anchors located in the concrete. The surfaces concreted using climbing formwork can be produced up to the quality of Siuhtbeton.

Climbing formwork has the disadvantage that additional lifting equipment, in particular construction cranes or the like, is required, "which is very often associated with considerable costs, particularly in the case of tall structures.

The object of the invention is now to create a climbing formwork in which the lifting of the individual formwork sections takes place through devices integrated in the oehalung, so that additional external hoists are not required, according to the invention, which is a snapping arrangement for concrete construction under Use of climbing formwork sections is concerned this task in a simple and advantageous manner thereby solved that Schie at the joints of the formwork sections a lifting device is provided are arranged. The individual üchalungaabsehnitte are included protruding downwards .tin & erverticals

The inventive climbing formwork is distinguished over the known ^ chalunsen by the fact that, especially at high B-uwersen a grösaere efficiency is achieved, since only one oehalun _b shoes is required, and sections raising the ücilialung by the 1 ¹ UIiTUn ₀ to dan individual üchalungs is made independent of wind effects *

In an advantageous further development of the invention, it is advisable to _{arrange a set of rollers on one side of the uchulun o} subschnitteü and on the other end a railing strip projecting upwards and downwards, which also serves as a support for the lifting device. But it also könnt.n at both ends of the Schalungsabsonnittes üollenfcutze be arranged, while in the rennfuge i ^T between the üollensätzen a two lifting devices, and rails for supporting the Hollen, located on the formwork according to the amount projecting beyond the top and bottom stator. This overhang can be formed from two convoluted, angular rail strips. Pollen corners are made, so the angled rails can also be set at an angle.

The studs of the roller sets are expediently mounted so that they can be displaced perpendicularly to the formwork in order to prevent the formwork from pushing off the concrete to the 2? » to enable the corner of lifting and bringing it into the formwork position. Thereby _; The sliding bearings for the lobes can be U-shaped and have spindles for adjusting the roller bearings, which are also U-shaped. 'Ie sliding bearing and the flat rails for the ■ ouble flanged rollers, the Iiollensätze may be used in the Sch & linden the coupling portions arranged elbows

ids lifting device is best to find one ^! > .inde or a pulley used according --ie there vorteilhaiterueise from the ichienenleisten fortified Umlenürollen and ouch üufwicke! drums for a ^ eilzu _cs. Around the outer drums there is an oeilschlinge so ϋδίβο ^ »that after lifting one b achalunysabschnittes the other _{one can also be lifted by üiakehrun o} the instruction sheet of the winding drum.

In the drawing, several exemplary embodiments are shown of the invention, namely shows:

The formwork according to the invention consists of the formwork panels 1 which, when arranged next to one another, result in the formwork sections A and B, the anchor verticals 2, the horizontal stiffeners 3 and the lifting device 4 · In the area of the Separation points of two formwork sections are shown on the the rail strip 5 on one side and the roller strip 6 on the other side. The rail strip protrudes nuch down by about half a formwork height and up by about one and a half formwork height. It is designed so that a self-supporting strong shuttering sheet 7 of Bar 5 abuts tightly but chordal shape against a likewise stiff shuttering sheet 8 of bar 6. Facing away from the concrete, a rail 9 made of flat iron is attached to the bar 5, which goes over twice the formwork height. At the Bar 5 is provided above a hollow 10 and below a roller 11. At a convenient height above the top of the concrete a winch or a pulley system 12 is attached, which is used to operate an upper file 13 and a lower rope 14 serves. Arranged on the bar 6 are two or more (J-shaped bearings 13 with adjusting spindles 16, each of which hold and guide a bracket 17. In this bracket there is one Double wheel rim roll 18 rotatably mounted

From Figures 2 to 5, the individual steps of the lifting gate can be seen; First, to remove the shuttering section A, loosen its incervertical from the anchors 19 and then operate the spindles 16 so that the shuttering is removed from the concrete remains. After completion of the lifting of the formwork A, it is again fixed in the area of the downwardly protruding anchor verticals at higher lying / inkerη 19, after the formwork is brought back into the concreting position by the spindles 16, the spindles 16 are grounded in the other Seal ₆ rotated so that the formwork B is pressed off the concrete over the rollers 18 together with the rail 9 after the inks 19 have been loosened Formwork B retightened. As soon as this has reached its height, the formwork skin B is also brought into the concreting position by actuating the spindle 16 and anchored again by means of the higher-lying anchors 19 in the area of the downwardly protruding anchor verticals 2. The anchors of the formwork facing A and the anchors of the formwork facing B in the area of the now free-standing formwork are then used and the concreting can now be carried out after any reinforcement that may be required has been introduced.

The device described above can be used in particular in the case of polygons or curved building verks, in particular in the case of structures that change conically upwards and thus require an adjustable formlining, can be modified in such a way that aiisser formwork A and the Formwork B still a stand C is arranged, which serves as a Hichtungiitändtr, as shown in Flg. 6 to 8 show. JUi this

Stands are then connected to the sill strips 5, while the clad strips 6 are attached to the formwork A and B are"

The workflow is basically the same as in the embodiment according to FIGS. 1 to 5 and is carried out in such a way that that first the formwork .4, then the formwork B and then sowing the vertical C can be raised. The intermediate anchoring conditions are analogous to the simple lifting mechanisms described above, however, there are two Lifting equipment 12 or a combined lifting equipment that can be used is required.

The stand ϋ serving as an un ^ svertical can also 8 be designed as a formwork corner.

In the Sohalungsausfuhrung according to FIGS. 1 to 5 the necessary i \ rbeitsrüstun _b fixed on the individual ächalungsabschnitten is mounted and is raised simultaneously with the cjchalung, while on the other hand which is intended in Figs. 6 to 8 illustrated Richtu% aständer C without doing work Since when it is used, the work equipment can protrude into the area of the stand, the security for the workers is given by the safe guidance of the bolts 18 and the secured hoists up to the leasing of the last / inker of the formwork to be lifted can be carried out safely. When lifting, the workers step on the work equipment of the neighboring formwork.
