Device for shuttering a prefabricated garage

The invention relates to a device for shuttering a prefabricated garage to be made of reinforced concrete with rare formwork walls, rear formwork walls and ceiling formwork walls, which are connected via parallelogram links and lifting devices Support frames are connected.

There are already internal formwork known in which the individual formwork walls are connected to a chassis via parallelogram links and hydraulic cylinders,

209829 / 03U

whose harvesters roll on rails. For shuttering the The hydraulic cylinders are extended to formwork walls, see above that the formwork walls move upwards and outwards into their closing position. But this creates between the edges of the individual formwork walls column, in which intermediate parts are inserted by hand and in this position need to be attached. The outer formwork must be off individual parts are assembled and fastened · After the prefabricated garage has hardened, first the outer formwork and then the inner formwork must be stripped out by retracting the hydraulic cylinder. The chassis the inner formwork can then be moved out of the open front of the prefabricated garage. Naturally 1st it is necessary with this known inner formwork that after the production of the box-shaped upper part of the prefabricated garage, a bottom part is attached to the same. In addition, a goal frame to accommodate the Garage doors can be inserted into the open front face. The connection of the floor and the goal frame with the box-shaped upper part can only be done through the reinforcing iron, is generally not very stable and requires additional operations.

On the other hand, it is known to attach outer formwork walls to one Suspend the support frame by means of parallelogram links so that when the support frame is lowered, for example by means of a crane hook, as a result of being placed on a floor formwork of the prefabricated garage by pivoting the Parallelogram links are automatically brought into the correct shell division. This switch-on position is always the same, so that a change in the

209829 / 03U

Wall thicknesses of the prefabricated garage is not possible. In addition, the opposing formwork walls must always be in pairs must be provided, otherwise the support frame will not remain in equilibrium.

There are already monolithic prefabricated garages with floors and attached goal frames known. For the production In these monolithic prefabricated garages, however, it is necessary, in particular, to use the inner formwork parts individually and to attach the BU and after the oarage has hardened to be taken out individually through the narrow doorway.

The present invention is not only intended to provide a device for shuttering a reinforced concrete, monolithic prefabricated garage with an integrally molded floor and goal frame are created, which can be switched on and off largely automatically, but rather at the same time the possibility should be created to vary the wall thicknesses of the prefabricated garage as desired, whereby the formwork holes automatically adjust to the selected wall thickness. Reinforcement of walls, ceilings or floors the prefabricated garage 1st z. B. with fire-retardant walls or to reinforce bearing walls or load-bearing ceilings Underground garages, row garages, multi-storey garages and the like are required. In the case of row garages, you can also Rarely or back walls are completely eliminated. In this case, there is only a support post left at the front or rear, which must have the thickness of the wall for normal garages and a greater thickness for underground garages. With the known Formwork devices it is necessary in these special cases to subsequently reinforce the walls.

209829 / 03U

This object is achieved according to the invention by a floor pallet that can be moved in the longitudinal direction of the prefabricated garage, two support frames, which can be moved in the transverse direction and are designed as chassis, for side and rear formwork walls Outer formwork and a support frame for side, rear and ceiling shuttering walls of an inner shuttering, which on at least two in the longitudinal direction from the garage floor area " staggered places is firmly connected to the floor.

This training makes it possible to produce a monolithic prefabricated garage with a floor and goal frame, according to ™ automatically stripping the exterior & chalet after setting and to drive away to the side and the inner formwork by means of the support frame supported on the ground outside the garage To be driven in so that the garage standing on the mobile floor pallet with the relatively narrow goal frame can be withdrawn and moved away via the retracted inner formwork in the opposite direction to the support frame mounting. This represents an enormous simplification compared to known devices, since, with the exception of the formwork point for the goal frame, all formwork parts, including the floor pallet, can be moved automatically and only minor handles for locking or unlocking the adjoining outer formwork parts are required to the entire monolithic To shape and drive off the garage body including the floor and goal frame.

in order to form the floor of the prefabricated garage resting on the floor pallet in one piece on the box-shaped upper part, it is preferably counteracted in a longitudinal direction

209829 / 03U

the formwork position offset station made and in not yet fully set on the floor pallet into the formwork point, whereupon the inner formwork and outer formwork are shuttered very quickly and almost fully automatically and a gate frame formwork is attached. Before or at the same time as this, the reinforcing steel is inserted and then the concrete is poured in so that it connects to the not yet set concrete on the floor pallet.

Due to the mobile mounting of the outer formwork parts, for example by arranging enclosures between the Edges of the floor pallet and the parts of the outer formwork as well as between the outer formwork parts themselves, in addition possible in a very simple way to change the wall thickness of the various walls of the prefabricated garage without the automatically abandon correct setting of the formwork parts or to make their operation more complicated.

Expedient embodiments of the invention are directed to the shape and storage of the floor pallet, outer formwork and inner formwork and the gate frame formwork to the To make actuation of these parts also more reliable and faster. This is how the floor pallet and External formwork increased by the fact that the floor pallet and the chassis for the external formwork have wheels that run on rails, with those in the transverse direction running rails for the chassis outside the in End rails running lengthways for the floor pallet. The movement of the chassis for the outer formwork takes place preferably by means of under the floor pallet

209829/0314

arranged thrust members, for example hydraulic cylinders or spindles, which act on the one hand on the ground and on the other hand on the chassis. Thereby hinder they neither the movement of the floor pallet nor other parts of the device.

In a preferred embodiment, the outer formwork consists of only two parts, each of which consists of a rare formwork wall and a half rigidly connected to it the rear shuttering wall, whereby the rear shuttering wall is halved in the vertical direction. In this embodiment, the thrust members therefore only have to move two parts in opposite directions in order to reach the outer formwork on or off the formwork.

It is advantageous not to make the external formwork point rigid, but via horizontally swiveling parallelograil links to be connected to the associated chassis, the side formwork walls each resting on a horizontal sliding layer attached to the associated chassis. This makes it possible to first place the external formwork in · to move sideways to the floor pallet in a position that has been shifted slightly to the rear and only when it is in contact of the side formwork walls on the floor pallet to push them forward until the rear formwork wall or the two Halves of the same rest on the floor pallet. Since the reinforcement rock somewhat over the dimensions of the Stand out from the floor pallet, otherwise it would be unavoidable that the reinforcing bars are damaged by the approach of the External formwork would be moved. Especially when arranging enclosures on the rear wall, these would

209829 / 03U

Bellages can otherwise be shifted slightly.

This shifting of the outer formwork point linked to the parallelogram link is expediently carried out also automatically in that the thrust members each attack one end of an angle lever, which is pivotably articulated on the associated chassis and the other end of which is pivotably connected to one end of a push rod, the other end of which is pivotably connected to it the associated side shuttering wall is connected. When retracting the thrust members, for example hydraulic cylinders, Therefore, the chassis are first moved laterally until the side formwork walls are in contact with the floor pallet. The outer formwork parts are shifted to the rear with respect to their final position, so that the parts of the The rear shuttering wall is not in contact with the floor pallet. When the hydraulic cylinders are retracted further, the angle levers are pivoted so that the side formwork walls over the Push rods are pushed forward until the rear shuttering wall also rests on the floor pallet. Vice versa When stripping the formwork, the external formwork point is first pushed backwards on the sliding layer on the chassis by actuating the hydraulic cylinder until the Angle levers are pivoted so far that the piston rods of the hydraulic cylinders engage directly on the side panels. Only then will the chassis be at further extension of the hydraulic cylinders pushed to the side on their rails until the halves of the rear shuttering wall have moved away from the track of the finished garage that can be moved on the floor pallet.

209829/0314

For a better connection of the outer formwork to the floor pallet, the parts of the outer formwork near their lower edge can preferably have recesses into which suitable · Projections on the floor pallet can intervene.

In addition, the two parts of the outer formwork can have tension locks along the parting line of the rear formwork wall, the width of which is in view of possible changes the wall thickness of the prefabricated garage can be adjusted by means of suitable inserts, which can be removed or inserted.

The support frame for the inner formwork is preferably made of at least two supports resting on the ground » Stored within the garage floor area and protrudes unsupported to a point near the rear wall of the garage. With the expression Garagengrundflflehe is the floor area meant above which the garage is located when it is switched on. This expression is also used in used in this sense.

This design of the support frame makes it possible to attach the Znnenschformungsteile to the support frame when stripping approach and pull it out of the goal frame opening with the same. However, since in the design according to the invention the support frame for the inner formwork is fixed, the prefabricated garage standing on the floor pallet is pulled away in the opposite direction over the support frame and inner formwork.

If there is an exact horizontal adjustment of the support frame

209829/0314

rüQi'l'lch appears, the pillar of the support frame, which is closer to the base of the coffin, can contain a hydraulic cylinder.

In a preferred embodiment, the form is the inner formwork divided into six separate, independently mounted parts on the support frame, namely two rare formwork walls, a ceiling shuttering wall, a rear shuttering wall and two base shuttering walls, which when switched off are like this are used on the support frame so that they can be pulled out of the opening of the goal frame.

The rare formwork walls are preferably each over in a vertical plane and to a lesser extent perpendicular to it pivotable parallelogram linkage via a trailing arm arranged approximately in the longitudinal direction of the garage and via at least two toggle levers with the support frame tied together. In this embodiment, the articulation points of the toggle levers are connected to one another by a rigid rod connected and the articulation point of the toggle lever is connected to one end of a lifting element, for example a hydraulic cylinder, connected, the other end of which is connected to the support frame. Lead when actuating the hydraulic cylinder therefore the side formwork walls are curved, outwards, backwards and upwards or movements directed in the opposite direction the end. When shuttering they are therefore from a position that does not interfere with the other inner shuttering parts Without hindering these other parts into the shuttering position, while they are being removed from the tied prefabricated garage and detached from the other formwork points and brought back into the retracted position will.

To this leadership of the rare formwork walls as well as the adjoining Facilitate the inner formwork point and the mutual sealing of the same in the formwork position ssu, the side shuttering walls preferably protrude at right angles and form parts of the ceiling and chopping shuttering wall • Margins on.

In order to form stiffeners known per se on the inner edges of the garage, in an advantageous embodiment the outer edges of the inner formwork beveled.

In a preferred embodiment of the ceiling formwork wall, this is via parallelogram links which can be pivoted in a vertical plane and via at least two lifting members, which are also pivotably mounted in a vertical plane connected to the support frame. The ceiling formwork wall preferably also has a vertically protruding, a part of the rear wall forming the edge.

While the nesting of the side formwork walls and the ceiling formwork wall in one another in the disengaged position, ie in the position drawn to the support frame, is still relatively easy with parallelogram links and trailing arms ψ , a somewhat more complicated mechanism is required for stripping the rear formwork wall. A preferred embodiment of this mechanism consists in that the rear formwork wall is connected to the ends of rigid connecting rods via parallelogram links which can be pivoted in a vertical plane. One end of these connecting rods is also connected to one end of an angle lever, while the other end of the same with one

209829 / C3H

End of a toggle lever with the parallelogram link forming another link connected let. The scold point of the angle lever or the other end of the further link is pivotable with the in this embodiment Support frame connected and the other end of the Winkelhebeiß 1st with one end of a lifting member, for example Hydraulic cylinder connected, the other end of which is pivotally connected to the support frame is. When the Hydraulic cylinder, the angle lever, which is preferably located at the lower end of the rear shuttering wall, is pivoted and the toggle lever, which is preferably located on the is located at the top of the rear formwork wall, is stretched, so that the rear shuttering wall extended backwards and downwards into the shuttering position via the parallelograimnlenker will.

The base shuttering walls are in a preferred embodiment each via a trailing arm running approximately in the longitudinal direction of the garage and via at least two Lifting elements, such as hydraulic cylinders, mounted pivotably in a horizontal and a vertical plane, connected to the support frame, the lifting members being pivotable between their ends by in a vertical plane Handlebars are also connected to the support frame. This storage of the plinth formwork walls ensures an arched shape Extension of the plinth formwork walls outwards, backwards and downwards into the shuttering position without obstruction the remaining interior formwork parts.

The additional links acting between the ends of the lifting elements can be loaded by springs in such a way that that the base shuttering walls in the shuttering position against

209829 / 03U

the lower edge of the side formwork walls are pressed.

The plinth formwork walls can be used to simplify the nesting during retraction and the sealing in the A peeling position also applies to a vertically protruding, have part of the rear shuttering wall forming edge.

For the simultaneous manufacture of the goal frame of the A gate frame formwork must be attached to the prefabricated garage. In a simple embodiment, this consists of . an outer gate frame formwork to be attached to the rare formwork walls "of the outer formwork" by means of tension locks and from an inner gate frame formwork firmly connected to the rare formwork walls or the ceiling formwork wall of the inner formwork. The inner door frame formwork can be used at an advantageous embodiment consist of shuttering sheets firmly seated on the inner formwork, which are located at Tighten the tension locks and apply a seal to the outer door frame formwork.

Each tension lock preferably consists of a toggle lever connected at its ends to the inner formwork and outer formwork, the hinge point of which is penetrated by a pressure spindle which is supported on the outer gate frame formwork inserted between the inner formwork and the outer formwork. If the knee lever is tightened by tightening the Tensioned the pressure spindle, a firm seal between the outer and inner gate frame formwork on the one hand and between the outer gate frame formwork is achieved at the same time and the side formwork walls or the ceiling formwork wall on the other hand achieved. The connection of the

Toggle lever with the inner formwork, while the connection with the outer formwork; can be done for example by a swivel joint. After the Fex ^j tiggarage has set, it is only necessary to loosen the connection with the inner formwork and remove the outer gate frame formwork.

To adjust the strength of the goal frame, a stop screw is preferably attached to each tension lock Adjustment of the position of the outer gate frame formwork provided.

The garage floor is expediently manufactured outside of the garage floor area, whereupon the floor The pallet with the garage floor that has not yet set is moved over the garage floor area and under the support frame of the indoor bracket. The inner formwork is then placed extended and the upper part of the garage reinforced with steel inserts. The outer formwork is then approached and possibly connected to the inner formwork and the floor pallet with the help of suitable means Concrete are introduced. When stripping the formwork, proceed in the reverse order. The finished one Garage is moved away from the garage floor area on the floor pallet and then by means of a crane lifted off the floor pallet and transported to the warehouse.

Figure 4 shows the outer formwork in plan. In this The illustration clearly shows the hydraulic cylinders 48 running below the floor pallet, which ones at one end each via a bearing block 68 with the Bottom and at the other end with one end of an angle lever 50 are pivotally connected. The angle levers are at the pivot point? O in each case on the associated chassis 44 stored. The opposite ends of the angle levers 50 are pivotably connected to a push rod 52, the opposite end of which is pivotably connected to the underside of the side formwork walls 36. In Figure 4 is the outer formwork shown in the switched-on state. They are used to reinforce the side walls and rear wall the prefabricated garage between the outer edges of the floor pallet and the side half walls 36 and the rear wall 42 Bellagen 72 inserted, which depending on the request can be replaced by thicker layers or omitted. When using the supplements shown 72, appropriate enclosures 74 must be inserted between the vertical edges of the two halves of the rear shuttering wall 42. In the embodiment shown, these two halves are fastened to one another by tension locks 76 known per se, wherein bell layers 78 can likewise be inserted into the tension locks or not, depending on whether and which enclosures 72 and 74 can be used.

This Versohwenken the angle lever 50 about the Schirenkpunkt 70, the push rods 52 are claimed to train and move the side formwork walls 36 to the rear by a corresponding distance. If doing too strong If friction occurs, the hydraulic cylinders 48 first press the side formwork walls slightly outwards and move only then to the rear. As soon as the legs of the angle lever 50 connected to the hydraulic cylinders If the chassis 44 are resting, they push the same outwards along the rails 46 into the position shown in FIG. The procedure is reversed when shuttering, with first of all the chassis 44 when the hydraulic cylinders 48 move into the one shown in FIGS. 3 and 4 Position. When the hydraulic cylinders 48 are retracted further, the angle levers 50 are moved around the Pivot point 70 is pivoted in the opposite direction, as a result of which the push rods 52 are subjected to thrust. This will put the already on the side the floor pallet 32 or resting against the bell layers 72 Side formwork walls 36, which are previously in a after located in the rearward shifted position, pushed forwards in the longitudinal direction until they are the position shown in FIG Have reached the position in which the rear wall 42 is also in contact with the floor pallet or the enclosures 72. This longitudinal displacement of the outer formwork parts is required because dl · reinforcing iron, like bars or mats, with their spacers protrude beyond the concrete dimensions. When the outer formwork was driven in, the Rückechalwand 42 take the reinforcement bars and spacers and move them. As can be seen, for example, in the case of a rear wall or side wall reinforcement

A special adjustment of the outer formwork is required, as it can be adjusted by applying to the floor palstts or the Bellagen automatically sets the correct size.

In Figure 5, the rear view of the outer formwork is shown. In the illustrated embodiment, the outer formwork point 36, 42 via parallelogram link 80 with connected to the chassis 44, so that the displacement of the side-form walls in the longitudinal direction is made possible. To facilitate this shift, the lower edges of the side formwork walls 36 rest on the chassis 44 attached sliding layers 82 made of anti-friction Material on. The sliding layers 82 also dampen the vibrating devices (not shown) for compaction of the concrete exerted on the outer formwork walls · The side formwork walls 36 are through a dash-dotted line shown «tension chain 84 clamped together, which after the collapse of the Outer formwork parts is tensioned. The hydraulic cylinders 48 are preferably below the floor pallet 32 in arranged in a channel, not shown. Side formwork walls 36 and rear formwork walls 42 have recesses 86, in which suitable projections of the floor pallet can engage. The recesses 86 of the side formwork walls are can be seen from FIG.
