Description

The present invention relates to this in the preamble Claimed. The present invention is concerned with this Facilitating building construction, especially in a construction with repetitive structures made of precast concrete and the like.

There are a large number of structures in particular filigree repetitive structures compared to the building dimensions, whereby these are prefabricated from concrete parts. For example only be multi-storey car parks, high-bay warehouses, roof levels and the like. called. A rational series production of such Concrete parts are used in other applications by the present applicant described, which are hereby fully incorporated by reference Disclosure purposes are incorporated, so that neither on the Manufacturing the parts themselves still on the types of different structures must be received.

In order to work cost-effectively, the precast concrete parts now have to not only be manufactured inexpensively, but also on be installed easily. For this, the assembly, d. H. the Moving the parts from a storage or manufacturing location the construction site into yours like a ceiling or a roof often clearly above ground end position be relieved.

Various hoists are known. So there is Lifting clamps for pipe shaft hangers that can grip concrete pipes or truss-mounted hook assemblies and the like Coil tipping hooks, which, however, are operated with care on the device ask yourself. In this context it should also be mentioned DE PS 19 05 308, which describes a crossbar.

It is also important that even under unfavorable Conditions on the construction site provide a high level of security for those there employees is desired. Also for this are often constructive improvements to existing equipment required. The assembly speed should still be high, the number of fitters low, the precision high.

It is desirable to address the problems of accident safety, At least assembly precision, speed and / or costs partially in at least one of the aspects listed alleviate.

The object of the present invention is to create something new to provide for commercial use.

This task is solved with the characteristics of the independent Expectations. Preferred embodiments can be found in the Dependent claims.

The present invention thus proposes a first Basic idea with an assembly arrangement for precast concrete parts an attacking device for attacking the precast concrete and Cable pulling means for jointly moving attacking means and Precast concrete part, which is provided for Precast concrete positioning continues from a shipment of the Pre-cast concrete independent by the cable pull movement Actuator means are provided.

It was therefore recognized as essential that an assembly can be much easier if the precast concrete regardless of its movement through the cable pulling means by at least one, possibly several additional actuators is positionable. In this way, when lifting already be ensured that the precast concrete is safe remains in the attack means, what with gripper-like Equipment where there is a tendency to jam can, is not exactly guaranteed and / or it can be achieved be that the precast concrete without more, at least without any other significant spending Movement of the cable means in or near the desired one Adjusted end position and / or without risk of accident Tilting, lifting and falling can be solved. Especially under favorable weather conditions, the entire Process of assembly, crane travel and casting of just one Person. That lost in the concrete Stop anchors become superfluous, which helps to reduce costs.

The attack means can initially on the front Attack precast concrete. This applies in particular to elongated horizontal precast concrete elements such as purlins, beams or bars of z. B. also usable in high-bay warehouses Kind of like all of them according to the proposals of the applicant according to other registrations, in particular with battery Rotary formwork can be produced. The attack on the The face of elongated precast concrete parts can be used on the one hand for Serve lifting, for example when using thorns from the front Recesses provided for the precast concrete part are approached, but it can also be a pure backup, for example, if the attack on the precast concrete from below and / or above takes place and only a side slipping out frontal securing attack should be avoided.

The precast concrete often has to be from one position be removed, in which they face to face close stand, for example when they are on flatbed trucks or others Means of transport are lined up in a row and / or if they are closely adjacent on the face as in Rotary formwork method come to an end. In one In this case, the precast concrete parts can have a fall, that is on their top a smaller extension in their Have longitudinal direction than on its underside and it can then the means of attack beveled accordingly also be provided with a complementary lintel.

The pulling means are preferred on a variety of Points attached to the attack means. With elongated Precast concrete is a bifilar suspension Attack means away from the center of gravity of the elongated precast concrete preferred towards the two opposite ends, to get an approximation through the cable pulling means to achieve horizontal alignment and thus the required To keep actuator travel small. Particularly preferred it is preferred if on at least one of the end faces on both ends, more than a point of attack for the Cable pull means is provided because then tilting of the attack medium is reduced. The bifilar or multifilament attacking rope pull means are preferred in not too merged a large distance from the attack, whereby on Place a crane hook or the like can intervene. It shows that in particular one Three-point suspension the tilting of the mounting crossbar both with and without load and especially between the Load levels significantly reduced.

The means of attack itself is used to transport the load have a typical C-shaped cross section and with at least two spaced forks under the Push the precast concrete around it at spaced locations partially undercut, which, however, because of the i. d. Usually only about 10 cm square wood supports and the heavy weights are not easy is. It can be provided the forks on which the load is designed to be pivotable, so that the Load lifting, for example of bars, sleepers or others elongated elements, these forks - if necessary made and preferably- especially remote-controlled Actuator-assisted locking of the assembly arrangement on the element itself, swiveled or driven under the element can and also after swiveling a swing away Fork supports in a position generally parallel to transporting element itself can be done. By a Locking the assembly arrangement on the element up to The swiveling away of the fork supports can end Tilting and / or tilting entrainment of the to transporting element can be safely avoided after storage. The operation can preferably be done remotely Actuator control take place. Movement termination is preferred acknowledged by means of display that can be seen from afar, for example by One or more flashing lights go out.

The actuator means can preferably be operated remotely, especially via radio. This makes assembly from a distance possible, which enables safe working, the Position from which the actuator means were actuated especially for an optimal view of the assembly and / or recording position can be selected.

In a particularly preferred variant on Attack means a local energy store and / or an energy source intended. These can be batteries, pressure accumulators and the like act; however, are particularly preferred local gensets and / or hydraulic gensets using the means of attack are also movable. It is possible and preferred if the units are modular and can be disconnected, about a drive for other construction site units such as Provide travel systems or the like.

The means of attack are typically designed to attack one End position to be struck, this striking can also be effected by means of an actuator, and then actuators are preferably provided to the Precast concrete in its final assembly position or at least very to move close to it.

The mounting arrangement can also and / or alternatively remote actuators include to the precast on To fix the attack means during the cable movement. The Actuator means can optionally on the attack means itself and / or be provided in the cable means when training with bifilar or multifilar suspension especially in the Pieces between the merging of the cable means and Plea. The shipment of precast and The actuator then takes place by moving the cable pulling means behind the merge, while fine positioning the Cable movement between merging and means of attack includes. That ropes that hang further down, like pull ropes, can be provided, it should be mentioned, especially turning around the vertical axis by hand.

The arrangement is used in particular for the high assembly of Precast concrete parts are used, especially those made from rotary formwork Precast concrete.

The invention is described below only by way of example Described drawings. In this shows:

Fig. 7 is a side view of the further embodiment of the mounting arrangement;

Figure 8 shows the final position and casting of finished parts, such as is achievable with the mounting assembly of Fig. 6.;

In Fig. 1 it is shown how a high-bay warehouse is assembled from vertically erected uprights and concrete bars to be fastened horizontally to create the pallet spaces. The concrete bars can be produced in a manner not to be explained in more detail here, with a large number of bars typically being installed in the high-bay warehouse shown.

The installation of the many bars is time-consuming and must therefore be simplified. A suggestion like a good one and precise connection can be achieved is that a complementary pair between the upright and concrete bars rod-shaped connecting means and sleeve into one another intervenes, that is, the edge bar is attached. This can be done with high precision, especially if this Verdollung has a beveled or tapered shape and is favored for self-adjustment. For this, the referenced registrations of the applicant. regardless to facilitate self-adjustment, however typically very heavy precast concrete parts in one enabling position.

A mounting arrangement 1 is therefore proposed according to the invention, which is only indicated schematically in FIG. 1 at 1 and (see FIG. 2) is formed from an attack means 2 for attacking a prefabricated concrete part 3 and cable pulling means 4 , which here as a crane leading single rope is realized, on which the entire truss-like assembly arrangement can be lifted, 3 actuators 5 a, 5 b, 5 c and 5 d being provided for positioning the precast concrete element, which are designed to position a precast element (independently) of to ensure a concrete part movement by moving the cable.

According to FIG. 2, different actuators 5 a, 5 b, 5 c, and 5d are now provided in order to position the prefabricated concrete part 3 without the cable pulling means for moving the prefabricated concrete part having to be moved, as from the different views in FIG. 2 visible and discussed in more detail, or to support the cable means movement.

According to FIG. 2, the application means 2 and the cable means 4 are bifilar at two engagement points 2 a1, a2 2 connected to each other, said spaced apart to end faces 3 a, 3 b of the precast concrete parts 3 are down. The bifilar attach rope piece means converge at a point 4 a, where a rope hook 4 b of a towering tower crane can be attached. The first actuator 5 a is now provided in one of the bifilar rope pieces, which in the present case are viewed as different from the actual cable pulling means moving the assembly arrangement, in the present case piece 4 c1, while no actuator is provided in the rope piece 4 c2.

The actuator 5 a is designed to shorten or lengthen part of the cable piece 4 c 1, with the result that the precast concrete part can be brought into a horizontal or desired oblique position. This happens while shortening the rope piece 4 c1, but regardless of a moving movement of the rope pull 4 b, to which the mounting arrangement is attached.

The actuator 5 a is now assigned a power source (not shown) which excites it. More precisely, the actuator 5 a is provided with an electric motor, which receives its power from an emergency power unit, also not shown, which is attached to the attack means 2, that is to say it is moved with it. The actuator 5 a for the horizontal alignment of the precast concrete element 3 is now assigned radio receivers for optional actuation via a radio link, the radio control device being operated by an operator 6 ( FIG. 1).

There is also an actuator 5 b for storing the precast concrete near the end position, which is designed to be able to bring a stop arm 5 c in a controlled manner to the bolt ( FIG. 1), where then a position in exactly that position by means of the horizontal movement actuator 5 c correct width can be reached, so that in particular an engagement of the pair of thickening (sleeve-peg) can take place between the precast concrete part and the post.

The arrangement works as follows:
The prefabricated concrete part 3 is first lifted to the recording and inclined for threading between the uprights, by the actuator 5 a remotely actuated. The arrangement is then moved to the installation site and the precast concrete part is guided close to the end position with the stop 5 c and the actuators 5 a and 5 b are moved for fine alignment. As soon as this has happened and the entanglement has come into effect, actuating elements, namely actuators 5 c, can also be used to release securing elements on the prefabricated concrete part.

The assembly described is therefore quick and risk-free as well as with the least effort with a simple to effect the structural part.

In this first exemplary embodiment, an assembly device for transoms as a device for the assembly of prefabricated concrete parts, with which a filigree repetitive structure realized as a high-bay warehouse is built, was presented with a traverse, the means of attack being constructed with the traverse attached to a crane (shown in Fig. 1) can be hung on ropes. It was shown how latches are to be attached to the assembly crossbar, the crossbar being attached to a hook via ropes, so that an automatic positioning or stabilization of the finished part under the hook can be effected with actuators in order to achieve the final position Slid latch for assembly.

The arrangement shown only schematically in FIGS. 1 and 2 is only exemplary and not mandatory with regard to the actuator selection etc. Fig. 3 shows that at about bifilar suspension of a concrete component 3 of engaging means 2, two actuators 5 a, 5 a ', ie one in each cable segment 4 c1, c2 4 may be provided.

Also, as shown in Fig. 9, use with a tower crane is not mandatory. Rather, an arrangement on a gantry crane can also be selected. The displacement of the prefabricated concrete part 3 relative to the attacking means 2 independently of a moving movement of the cable suspension means or traction means relative to the crane is illustrated by the arrows 7 , 7 ', which indicate the movement of a bolt by actuators.

Another example of a final assembly of an edge bolt is shown in FIG. 4. Here, the upright plate is illustrated by the reference numeral 8, wherein a visible anchor bolts 8 a is provided on the upright disc. 8 The anchor bolts 8 a has a keyhole-like opening (8a1, comp. Fig. 4c) into which a hook-shaped element can penetrate aktuatorbetätigtes 5 e1.

The embodiment is now formed so that the mounting arrangement of the invention acts on the precast concrete part 3 by pins 2 b of the engagement means by those sleeves 3b of the concrete component 3 enter, which are for the later mounting on the pin 8 of the upright disc 8 b determined. These pins 2 b have a slightly larger diameter than the pins 8 b on the standing plate on which the sleeve is to be placed. The inclusion over the sleeves also saves fixed stop sleeves.

Electrically actuated spindle motors 5 f and 5 g are provided on the mounting device, of which the spindle motor 5 f as actuator moves a spindle pressing against the precast concrete element parallel to the pin 2 b and the actuator, ie the spindle motor 5 g, is hook-shaped Element Sel moves.

With the arrangement, a bar end assembly of a received and, if necessary, horizontally aligned, and, in the present case via a traction cable 4 d, brought close to its end position into the end position, first by hook 5 e1 with the spindle extended into keyhole-like opening 8 a1 the standing disc sleeve is inserted. Then the actuator 5 g is actuated, which brings the attacking means 2 towards the standing plate 8 and fixes the attacking means 2 on the standing disc by rotating the hook relative to the opening 8 a1. Now the spindle motor 5 f is activated, which moves the locking element from the support on the now fixed attack means 2 to the pin 8 b on the standing plate 8 . This shift is facilitated because the diameter of the sleeve 8 b is slightly smaller than that of the attack means 2 . After the precast concrete from the initial position VDE, it is shown in Fig. 4b, has been moved into the end position after Figut 4 a, the spindle 5 is retracted f and then the spindle 5 g to such a rotation is moved back, the hook däss from the opening 8 a1 can emerge. The assembly arrangement can thus be removed.

While the attacking means described above were only suspended with one rope element on each end face, it is preferred to effect a multi-point suspension by fastening two rope elements at least on one end face, which run towards the crane hook. The reason for this can be seen from FIG. 5, where it is shown that then substantially smaller inclined positions of the precast concrete part are to be expected, which will further increase the overall operational safety and simplify handling. It is clear that in a three- or multi-point suspension, several actuators can also be present in individual cable segments for securing the position and / or taking up a position, as indicated at 5h and 5i.

Another embodiment is shown with reference to FIGS. 6 and 7. This is preferred due to the use of only a single actuator while still having a very high level of operational safety and simple operation and maintenance.

According to FIG. 6, generally designated with 100 mounting arrangement for precast concrete elements 101 is such here. B. roof greases with an attacking agent, comprising two forks that can reach under the precast element 101 , and further formed by lateral fuses 102 a, which are designed to secure the precast element 101 against falling out laterally.

The forks 102 are provided on a crossbar 103 which, on the side 103a ( FIG. 7) which is at the top during operation, has points of attack for a multifilament suspension 104 which leads to a tower crane or the like.

The crossbar 103 is telescopic, so that it can be easily adapted to precast concrete parts 101 of different lengths. The side parts 102 , as can be seen in FIG. 6, are formed in such a way that a prefabricated concrete part is secured against falling out and, moreover, wherein the extension of the horizontal cross strut telescope 103 is also possible as far as possible so that an adaptation to the dimension of the respective prefabricated concrete part can be ensured. The assembly arrangement is immovable relative to the precast element as soon as and as long as the side wings grip around the end edges of the precast element or are slipped over it, in order to facilitate striking and / or to prevent jamming. In addition, the side parts must also be adapted to differently thick concrete parts.

The forks 102 are now driven by a hydraulic cylinder 105, which here forms the actuator and is pressure-fed from a (not shown), with the arrangement mitbeweglichen drive assembly, pivotably connected to the forks articulated swivel joints 106th For this purpose, the latter engages an eccentric arrangement 106 a, via which the forks can be pivoted from a position generally parallel to the cross member 103 and thus parallel to the longitudinal edge of a precast concrete element into a position below the precast concrete element, as shown in FIG. 7; the hydraulic cylinder 105 is at the same time also arranged to cause the forks to pivot back from below a prefabricated concrete part back into a position parallel to the cross strut 103 via the eccentric means 106 a. The distance between the upper edge of the fork and the upper side 103 a of the cross member can be adjusted by means of a vertical telescopic movement of a further telescopic extension 107 from FIG. 7. The front of the fork is bevelled, both towards the precast concrete and towards the floor. The thickness of the fork tines 102 b is selected so that a concrete part to be picked up can be carried safely, but there is still enough ground clearance to take it up when it is standing on squared timber typically about 10 cm thick.

There is also a signal device 108 in the form of two, redundantly provided and flashing lights which can be detected from a wide perspective, which indicates whether a pivoting movement of the forks into the parallel position or the load-bearing position under the prefabricated concrete part, in which the overall arrangement is generally C-shaped sits, is complete.

A remote control is assigned to the hydraulic cylinder 105 in order to enable the forks to be pivoted remotely into the load suspension or, in the opposite direction, into the parallel position.

The side wings 102 a are dimensioned in such a way that a precast concrete part of the type to be accommodated can be held securely against falling out even when the overall assembly arrangement is roughly inclined, without the side wings being able to bend. At the same time, the dimensioning is selected such that a close juxtaposition of precast concrete parts face to face or picking up the same is readily possible if, for example, in the case of a rotary battery formwork, finished parts are after stripping. The face-securing wings can also be adapted to a concrete lintel to make it easier to strike and / or knock off. Furthermore, two guide ropes 109 are provided on the arrangement.

The preferred arrangement works as follows:
First, the assembly arrangement is moved with forks pivoted parallel to the cross member to a precast concrete part to be picked up by a square timber, which can be done by moving the cable pulling means 104 from a tower crane. Then the assembly arrangement 100 is lowered onto the precast concrete part 101 in such a way that the lateral securing wings 102 sit on it and / or clasp it. The assembly arrangement is then fixed relative to the precast concrete. Now the forks 102 can be pivoted by remote control of the hydraulic cylinder 105 under the precast concrete part, which sits on a square timber. If there are unevenness in the floor below the precast concrete part or in the swivel range of the forks, for example due to pebbles or the like, this does not lead to a shift in the overall arrangement relative to the precast concrete part, since the assembly arrangement is already fixed relative to the precast concrete part by the side brackets 102 a. Rather, pebbles and the like are pushed aside. The corresponding horizontal alignment can be done by a single person due to the multifilar suspension. B. easily accomplished on a handle (not shown), if necessary.

As soon as the end position of the fork swivel movement is reached, this is acknowledged by the flashing light 108 . The received precast concrete element 101 can now be brought into an assembly position on the assembly arrangement 100 , as is shown, for example, in FIG. 8, alignment with the guide cables 109 can take place.

If a bag filled with liquid mortar and pierceable by the peg is brought into a recess in the precast concrete part 101 for a peg, which is possibly possible on the concrete element still stored in the square timber, then after lowering the precast concrete part onto the peg, these bags can be pierced and it potting is no longer necessary. During the hardening of the mortar, if necessary, no bag should be used, even immediately after setting it down, the forks 102 can be pivoted away from below the precast concrete element by actuating the cylinder 105 again , now in the other direction. At this time, since the assembly arrangement is still fixed to the precast element by the side wings, there is no risk that the precast element will fall down or be carried away during the swiveling movement. The end of the pivoting movement of the forks 102 back into the parallel position is acknowledged again, which can be done by turning off a flashing light, and the entire assembly arrangement can then be lifted away without the risk that the precast concrete element is torn from the end position reached, since the lifting path through the swung out forks is completely free.
