Facility »for approximately horizontal transport and carrying of Construction materials for use in multi-storey buildings

The invention relates to a device for the approximately horizontal transport and support of construction formwork for use in multi-storey buildings, dia a device that extends over the construction formwork and with the interposition of a device Has lifting hooks of a crane 3 or the like that can be coupled, the one at one end over a load-transferring piece rides one Formwork floor or the like. The supporting frame of the structural formwork interacts.

With facilities of this type, the building formwork is on an already finished floor was erected. Then the Concrete on the surface:.: · 3 formwork elements poured * After the The formwork element will set against the lower one Part of the supporting frame lowered so far that it no longer supports the floor that has just been completed. Now that's the one below this floor located formwork is removed, raised to the height of a floor and placed on the surface of the previously finished floor, so that the next floor of the building can be poured.

To raise the formwork to the next floor and isum lowering the same after completion of the construction work, an essentially U-shaped device is known which swei; _:

has horizontal arms arranged at a vertical distance: which are supported by a downwardly extending load-transferring piece, which forms the connecting web of the U-shaped device with one another are connected. The lower arm acts as a formwork beam that supports the underside of the formwork element when it is lifted, while at one point, namely at the free end of the upper lever arm of the lifting hook of a tower crane or another crane attacks.

When the U-shaped device is in Lifting contact is brought and is raised or lowered by the crane, is - which is desirable in itself - the common Center of gravity of the formwork and the facility on the same vertical line as the crane hook. This becomes a unwanted tilting when maneuvering as well as lifting and lowering of the formwork avoided in a simple manner. This center of gravity however, it is usually not in the same location as the center of gravity, which is the U-shaped device alone owns. This is due to the fact that the majority of the mass of the U-shaped device in the area of each other connected cantilever arms and because the overall length of the various building formwork varies in the longitudinal direction of the arms. This results in the coupling and removal of the Construction formwork causes considerable difficulties because the facility is tilted to the side according to its center of gravity. this can lead to injuries to those working in the area of the facility. There is also the risk that the sturdy Lower boom when tilting sideways, the construction formwork scaffolding tears or at least significantly damages the supports of the formwork scaffolding. Therefore, when lowering the facility several craftsmen guide the lower boom and fix it until it rests on the ground. Then it may be necessary to use the To move the fastening bolts for the lifting hook in the direction of the center of gravity of the device, so that the device is after lifting it again without hooking it on the building formwork base or

can be extended laterally from the storey on the shoring.

The known design is therefore cumbersome to handle, prone to failure and accident-prone.

The invention is therefore based on the object of creating a device of the same generic type that not only is easier to set up, but also enables quick and accident-free work, even at great heights, e.g. when building high-rise buildings by means of dream cranes.

This object is achieved according to the invention in that the boom in the area of the load-carrying piece on the support frame is removably attached and that by securing elements fixable in a predetermined position against displacement on both sides Device for the attack of the lifting hook is adjustable in a known manner in the longitudinal direction of the boom. Result from this There are essentially the following advantages over the well-known design:

a) Because of the interpretation * with a device for the attack of the lifting hook of a crane is provided, which extends in the longitudinal direction of the Boom is adjustable »the operator can adjust the setting according to the known position of the center of gravity of the formwork to be lifted in advance, so that it is ensured that the Formwork element and the boom, if the device is connected to the frame supporting the formwork, without further adjustment lie essentially horizontally when they are raised or lowered by the crane. Special means that this horizontal position adhere to are dispensable.

In addition, the device for attaching the The lifting hooks remain in their set position when formwork of the same type and size is to be transported. A repetitive

909840/0358

Adjustment between the transports of individual building formwork is therefore not required.

b) After dna shoring with the relevant formwork to which Laje has been brought before becomes the boom easily disengaged and driven away. Dar Aueleger turns is around the lifting hook according to its center of gravity, however, it is not necessary to keep the boom horizontal by special means or by adjusting the lifting hook application point accordingly.

c) There is a lower, daa supporting structure when setting up supporting Aualeger dispensable. This is the inventive Establishment particular simple in its structure. Also iat aie Compared to the known design, it is lighter and can be verified significantly better maneuver, which is not when working on high-rise buildings importance to be underestimated iat.

d) In cases in which the weights or di Dimensional ratio of the structural formwork to be transported and To change supporting equipment, the crane hook can be shifted in the longitudinal direction according to the laying out the new conditions so that it can be used when coupling dee Aualegera, i.e. when lifting and transporting the structural formwork, results in a horizontal position for the Aueleger and the shoring. There are fork-like load suspension devices known, like them - with certain modifications - can also be used in forklift trucks, whereby the suspension point for the crane hook or the like is in Can move the longitudinal direction of the upper fork arms, "such that after lifting the load and the saber arm · essentially hori to

Transporting and carrying construction formwork. Although the Transport the load and fork arms horizontally, but after the load has been set down there is the disadvantage that the entire Load suspension device according to its center of mass around the crane hook or the like. Rotates so that a new one can be picked up Load not easily possible i3t. If you can avoid this turning wanted, it would be necessary to place the load handling equipment on the floor, the suspension point for the crane hook or the like. to move in the longitudinal direction of the forks and ainzujustieren so that after dam lifting the fork assumes a horizontal position. To this end, it would be necessary to try several times accordingly. Only then could the load handling device be in a horizontal position be transported away. After picking up a load, the suspension point for the crane hook or the like would have to be repeated according to the new common center of mass be adjusted so that the Load suspension device - now loaded - also assumes a horizontal position during transport.

According to a further feature of the invention, diasa is characterized in that the Auslagar in the area of the load-transmitting Piece is coupled to the support frame for the formwork element by at least one articulated connection, which one in vertical plane directed pivoting movement of the boom approximately between its essentially horizontal position and a position, in which the boom is alone hanging on the crane hook is allowed.

According to the invention, the articulation is on that of the free The end of the swap farthest away at the opposite end The end section of the hinge is arranged in such a way that the articulated connection, if sia with the supporting frame of the formwork elements3 resp. the -Ia3tübartragenden piece or the like.

The connecting chains allow easy and quick coupling and uncoupling of the boom, which can be done by an operator can be done while the articulation by lowering the lifting hook and placing the relevant part of the The boom is brought into coupling contact on the load-transferring piece without the operator having to intervene for the connecting chains. After loosening the connecting chains the joint connection can be uncoupled again just as easily by lifting the boom, i.e. lifting the crane hook " A reversal of the boom does not need to be observed either when coupling or when detaching from the supporting structure, as the boom can only perform a vertical pivoting movement with respect to the articulated connection.

The device according to the invention can also be provided with a connecting piece, which with the downwardly extending load-transmitting piece is connected, the connecting piece being detachably connectable to one end of the support frame is.

Another feature of the invention is that the device has a connector which both with the load-transferring piece as well as with the substantially vertical, the load-transferring piece facing side of the support frame is releasably coupled.

The connecting piece and the support frame can also be formed in one piece, the connecting piece being different from the one to be produced Floor or from the ceiling protrudes over one end of the support frame and at its upper end releasably with the load-transmitting piece is connected.
