Definitions

the invention relates to a method for producing a large, high, one-sided open prefabricated part made of reinforced concrete, in particular a room cell with a floor and four essentially vertical side walls, which using an external formwork, a floor formwork frame and a rectangular core formwork with five formwork walls with the The floor is concreted in one pour and is then to be tilted into its operating position.
the invention further relates to an apparatus for performing the method.
a manufacturing process is already known from DT-AS 2.400.390, in which the room cell is concreted on a tilting table, by means of which it is tilted by 90 ° after the concrete has set, so that the core formwork can be pulled out to the side.
This known method is used to make tall hall structures or deep concrete pits in the hall superfluous, for removing the core formwork and to avoid cracks in the room cell during the first tilting process by 90 ° and the second tilting process by another 90 °, since the core is the room cell made of fresh concrete.
the unsupported longitudinal wall must be supported.
a major disadvantage is that the room cell must be tilted together with the core formwork, so that the tilting table must be designed for the total weight of both.
a further disadvantage is that the core formwork has to be transported to the tilting table and locked there with exact dimensions and later transported out of the room cell and tipped back.
the tilting stress of the formwork core affects the dimensional accuracy of the room cell. If there are high production halls or deep concrete pits in the hall anyway, either the room cell can be pulled up from the core formwork or the core formwork can be pulled down from the room cell. All that then has to be turned is the empty space cell, freed from the weight of the core formwork.
this manufacturing process has the disadvantage that one would have to wait until the room cell has fully hardened if one wants to avoid damage when stripping and turning.
the invention is based on the task of developing a method of the type described in the introduction, in which the disadvantages of the known methods are avoided, the not fully cured finished part for further processing, i.e. without the aid of a tilting device designed for heavier loads and without tilting the formwork core without Damage can be turned into the operating situation with the open side facing up.
a device for performing this method is to be created.
the advantage of the method according to the invention lies in the fact that the side walls of the prefabricated part are not deformed when the prefabricated part is removed from the mold and turned, the concrete is essentially only subjected to pressure and thus cannot crack, although the prefabricated part has not yet hardened.
the tilting tables only have to be designed for the weight of the finished part. Nevertheless, in a further development of the invention, by means of suitable measures, for example by means of spacing elements, a platform or the possibility of moving up the initially vertical leg of the second tilting table, all the heights of the precast parts can be produced as in the already known method. i
the support device required to support the longitudinal wall of the finished part, which is exposed when turning is designed as a support beam which is connected to the platform in an articulated manner, so that it is transferred to the second tilting table together with the platform without relative movement to the finished part can be. It has also proven to be advantageous that the finished part does not have to be placed on the first tilting table with great precision so that one of its side walls lies directly against the vertical leg of the tilting table. By interposing the movable platform, it is possible to compensate for any remaining gap by closing the platform.
the solution to the problem on which the invention is based also includes several devices for carrying out the method according to the invention, the features of which are essential to the invention. a. refer to the lifting device, the platform, the spacers and the support device. They are the subject of claims 3 to 16.
a core formwork 11 and outer formwork walls 12 are used to produce a room cell 10 in a known manner, of which only three outer formwork walls are shown in FIG. 1 for the sake of clarity.
the reinforced core formwork 11 rests on a floor formwork frame, which consists of longitudinal boards 13 and transverse boards 14 arranged separately from one another.
the concreting process of the room cell 10 takes place in the so-called bell casting process.
the only open side of the room cell 10 points downwards, so that the room cell can be concreted in one pour.
the room cell 10, which is still made of fresh concrete, is lifted after removing the outer formwork walls 12 and releasing the four vertical walls of the core formwork 11 by means of a hydraulic device 15, which engages under the longitudinal boards 13 of the floor formwork frame, in such a way that the room cell is only subjected to pressure.
the core formwork 11 and the room cell 10 on the ceiling mirror from each other other separated and the cross boards 14 of the floor formwork frame solved.
the space cell 10 can now be lifted off the core formwork 11 by means of a special cross member 16 (FIG.
a platform 20 which is arranged parallel to the leg 19 and is hydraulically moved to the longitudinal wall of the room cell.
this platform 20 is mounted on a sliding carriage 21, which in turn is fastened to the leg 19 by means of rollers 22 and can roll on this.
a support beam 23 is leaned against the inner wall of the room cell longitudinal wall facing away from the leg 19, which is articulated to the sliding carriage 21 and takes over the support of the room cell longitudinal wall when the room cell is tilted.
the first tilting table 18 is then tilted by 90 °, so that the originally vertical leg 19 engages in a comb-like manner in the horizontal leg 24 of a second L-shaped tilting table 25 and the sliding carriage 21 with its rollers 22 rests on the fork carriers of this horizontal leg 24 ( Fig. 5).
the room cell 10 is now moved up to the vertical leg 26 of the second tilting table 25 (FIG. 6).
the room cell 10 on the second tilting table 25 can also be tilted by 90 °, so that the bottom of the room cell points downward.
the support beam 23 has been pivoted out of the room cell 10, it can be lifted from the second tilting table 25 by means of a cross member 27 and transported for further processing (FIG. 7).
the distance between the room cell 10 and the vertical legs 19 and 26 of the first and second tilting tables 18 and 25 can also be bridged by spacer elements which are expediently installed in the vertical legs and which preferably each have a platform, the plane of which is parallel to the Leg plane runs and which can be moved hydraulically in the direction of their normal up to the room cell 10.
spacer elements made of inflatable, tear-resistant rubber or plastic pillows, which are inserted between the relevant room cell wall and the vertical leg.
the platform 20 can also be attached directly to the vertical leg 19 or 26 without the interposition of a sliding carriage 21.
the fork supports of the horizontal leg 24 of the second tilting table 25, on which the platform 20 then sits when tilting have sliding rollers or runners on which the platform together with the room cell 10 until it rests against the vertical leg 26 of the second tilting table 25 can be moved.
a further possibility of bridging a possible distance between the room cell 10 and the vertical legs 19 or 26 is that the vertical legs themselves are moved in the direction of their normal up to contact with the room cell 10.
An arrangement in which the vertical leg 26 of the second tilting table 25 can be moved in this way is shown in FIG. 8.
the support bracket 23 for supporting the longitudinal wall of the room cell during tilting represents only one possibility of the many conceivable supporting devices.
the support bracket 23 has a limit switch, not shown in the drawing, which indicates the system on the inner wall.
Another possibility of support is shown in Fig. 9.
the support device consists of a support frame 28 which is pushed over part of the length or the entire length between the two longitudinal walls of the room cells. This is expediently done when the room cell 10 is lifted off the core formwork 11 with the aid of the special cross member 16, but has not yet been placed on the first tilting table 18. ,
the lifting device which is divided into the hydraulic device 15 and the special traverse 16 in the exemplary embodiment, can be combined in a uniform lifting device, as long as it is guaranteed that the finished part is only subjected to pressure during lifting by the lifting device in all working phases.
