Description

The invention relates to a guide shoe and a lifting device for use in the construction industry.
In particular, in the construction industry, it is known to use self-elevating devices in the construction of multi-story and particularly preferably tall buildings. This is ensured by the formwork necessary in the construction of the vertical walls of the building. As soon as the recently constructed walls are sufficiently hardened, hoisting drives are installed on them with the help of appropriate profiles to raise the so-called scaffold elements bearing the formwork, so that the vertical walls can grow further in the direction of the space above. When these walls are constructed, the scaffold element drives “follow” higher to raise the scaffold elements above the newly constructed section as soon as it has sufficiently hardened.
A device of this type is known from US Pat. No. 4,962,828. In this case, the scaffold element does not necessarily contain the formwork, but, for example, contains a safety net and / or platforms protruding outward from the structure under construction to provide access to the structure under construction, including the floor, which they put it there. The last elements are attached to the forest element. In addition, profiles can be attached to individual points of the structure, and a switchable drive is provided for lifting either scaffold elements or profiles intended for attachment to the structure.
A formwork lifting system is known, which is referred to as SKE, by which the vertical profiles on which the drives for lifting the scaffold element can be mounted are attached to the structure. In an alternative operating position, the drives are mounted on a scaffold element, which at this moment is suspended and / or attached to the structure in order to thus be able to raise vertical profiles to a new zone.
The main objective of the invention is to provide a guide shoe and a lifting device for use in the construction industry, which have been improved in terms of installation efficiency.
This task is achieved using the guide shoe described in paragraph 1 of the claims, and the lifting device with which the shoe is equipped. Preferred improvements are described in the following claims.
The possibility of disconnecting the guide from the scaffold element of the lifting system is suitably achieved by the fact that the guide shoe, which will also be referred to as the guide in the future, contains at least one guide grip that can move in the horizontal direction and rotate around a horizontal axis and which covers the profile for example, a T-, I- or U-shaped profile, part or section of a profile. For example, at least one profile provided on the scaffold element may be a T-shaped or I-shaped profile, the horizontal (like the letter "T") part of which is parallel to the outer side of the structure and directed towards it. In this case, the guide grip can be engaged on this part at the rear in the region of the vertical part “T” and can be disengaged by horizontal displacement and retracted by rotation around a large part of the horizontal axis. A further advantage of the rotating attachment of at least one guide grip to the guide is that discrete loads can be avoided when the guide attaching to the support on the structure rotates. That is, as will be described later with reference to the drawings, when the scaffold element is mounted on the guide, the slope occurs in such a way that the guide (shown in cross section) is located separately or (shown in three-dimensional space) along the line on the profile, and here high loads may occur. This can advantageously be avoided by means of guide grips arranged to rotate on the guides.
The guide shoe may be located on the lifting drive of the lifting device. In addition, the guide shoe may be attached to a wall shoe attached to the structure, and / or the scaffold element of the lifting device may be guided by the guide shoe.
In addition, it was found appropriate to make the distance between the axis of rotation, around which the guide grip can be rotated, and the outer end of the guide grip less than the distance between the axis of rotation and the connection between the guide and the wall shoe. Advantageously, this prevents the connection between the guide and the wall shoe from obstructing the rotation of the guide catch.
Therefore, a guide shoe of this type effectively acts as a direct connection between the lifting drives and the supports on the structure and / or the guides of the scaffold element, which is, in particular, an advantage when this element is raised. Moreover, the following features are preferred, both on their own and in combination with further features: providing two cams or support bolts with corresponding guides, as described below; a rotating connection between the guide shoe and the wall shoe; alignment with a rotating support, using a spring or other elastic element, such as a rubber buffer, for the planar support of the guide shoe, as described in more detail below; the direction of the guide teeth or grips along the guide shoe, which in some areas, for example, in the case of a square or other polygon, is made non-rotatable, and in some areas rotary, to rotate the guide teeth after axial movement, as will be described in more detail below with reference to FIG. 7.
The lifting device described herein, which is preferably a self-lifting device, described as such below, comprises at least one scaffold element that can be guided and / or suspended from at least one guide shoe, as described above, on a structure . Work platforms, formwork and similar elements necessary for tasks that need to be performed on the scaffolds are attached to the scaffold element. With respect to the scaffold element, it should be noted that in accordance with the invention it should contain load-bearing profiles on only one plane. Even though additional load-bearing profiles can be provided, the scaffold element can be made quite simple due to the fact that only one plane with load-bearing profiles is provided, which is in particular provided near the structure to reduce forces and moments caused by the application of vertical forces to designs. Guides along which the scaffold element can be guided and / or hung, for example, can be made in the form of a wall shoe attached to the structure. In particular, it is currently preferred to design the scaffold element so that it is suspended from a building in its upper part. In the lower part, the guide can be located on the so-called guide shoe, which, for example, can be connected to an additional wall shoe and which should be considered as part of the lifting drive described below.
In accordance with the invention, the self-lifting device comprises at least one lifting drive that can be connected directly to individual points on the structure. Advantageously, the drive forms one additional second vertical plane in addition to the vertical plane of the supporting profiles of the scaffold element. In particular, the drive does not have elements arranged parallel to each other in the lifting direction. While the drive can be directly attached to the structure, for example, using one or more guide shoes, which can be connected to the wall shoes on the building, additional vertical profiles are not required, as required by the prior art. A self-elevating device in accordance with the invention may have a rather simple structure. Only individual supports should be located on the structure, such as, for example, wall shoes. The only object located between these separate supports and the scaffold element is the drive, including optionally provided guide shoes, without the need for an additional vertical plane. This makes it relatively easy to install a self-lifting system.
In addition, the hoisting drive, which can be detachably attached to the structure, can be switched between a first operating mode in which the scaffold element can be raised and a second operating mode in which the lifting drive can be raised. As a result of this, the required lifting can be carried out in an efficient manner without the need to use, for example, a crane for lifting either a scaffold element or the provided drives. In this regard, in principle, such an option is possible in which the hoisting drive operates only in the first operating mode between the supports located on the structure and the scaffold element, while in the second operating mode the drive is dismantled and manually lifted by the workers to a higher area. In this case, the advantage in accordance with the invention is that the drive can be made small and light enough so that this process can be performed by workers with relatively little effort.
To connect the lifting drive to the scaffold element, the use of raised lifting hooks was recognized to be effective. With a simple design, hoists of this type provide support in the right places with the appropriate lifting movement. However, it should be noted that the invention can also be carried out with engaging parts made in the form of recesses, in the form of holes, such as in a perforated profile, in the form of protrusions, such as on a gear rack, or in another way.
In addition, at the moment it is preferable that at least one guide can be detached from the scaffold element. This has the advantage that the hoist drive can be separated from the scaffold element as a unit and, therefore, for example, can be manually transferred to a higher area. This contributes to the so-called partial hydraulic operating mode, in which the hoist drives only work when the scaffold element is raised. In addition, through the use of removable lifting drives, a convenient combination of actions is possible in which the scaffold element is lifted at least partially by a crane. In this regard, it should be noted that disconnecting the guide from the scaffold element in particular makes it possible to remove the drive from the scaffold element when one or more of its profiles are located in the guide region. The measures described also mean that it is possible to remove the drive at this moment, while otherwise it would be necessary to wait for the moment when the scaffold element would rise high enough to leave the guide area, which could then be removed from the supports on the structure, for example, from wall shoes.
For those hoist drive elements that transmit hoist forces to the scaffold element, the use of at least one cam and / or at least one support bolt has been found to be suitable. Preferably, the cam or the support bolt are under the influence of gravity in the first operating mode and under the action of the compression force of the spring in the second operating mode. Obviously, this can be done in the opposite way, so that the cam or the support bolt are under the action of the compression force of the spring in the first operating mode and under the action of gravity in the second operating mode or under the action of gravity in both operating modes, or under the action of the compression force springs in both operating modes.
In this regard, it is further preferable for at least two cams or support bolts to be located one above the other on the drive in the lifting direction. This makes it possible to suitably carry out further separation into “steps” during the lifting movement of the scaffold or drive element. This separation is first determined by the engaging elements on the scaffold element, for example, the distance between the lifting hooks. If, however, two or more cams or support bolts are mounted on the rails, then optionally one or the other cam or one or the other support bolt may engage with a separate lifting hook so that the “separation” is more frequent. For example, the distance between the lifting hooks 22 may be 300 mm in each case, while the two support bolts 80 are provided at a distance of 150 mm, so that a separation of 150 mm is obtained. Moreover, for the first or second operating mode, separate cams and / or support bolts may be provided.
In the case of the use of support bolts, it was deemed suitable to provide at least one guide circuit comprising one lower flat part and one upper inclined part. The upper inclined part makes it possible to use a support bolt, which is under the action of gravity, which quickly falls down in this area due to the inclined implementation of the guide contour. Advantageously, the lower flat part allows easy deflection of the support bolt, which is necessary if the lifting hooks of the scaffold element must extend beyond the support bolts, as will be described in more detail below, which is achieved by at least temporarily deflecting the latter.
In principle, it is possible in each case to carry out a separate cam or a separate support bolt so that both operating modes are possible. However, at the moment it is preferable to provide at least one locking dog, which in the first operating mode is preferably latched, and in the second operating mode, ensures that the drive is “pulled” to the support using the locking dog on the scaffold element.
For safety during operation, it is further preferred that at least one drive is held and / or loaded with a support and / or gravity in the direction of the scaffold element.
With regard to the design of the scaffold element, it should be taken into account that it can carry and / or carry significant weight that can only be transmitted through the structure. Consequently, the forces of weight and other forces acting at a distance on the structure tend to deform the element of the scaffolds away from the structure. Thus, it was considered expedient for the element of the scaffolds to have at least one prestressed support in an area remote from the structure. This support can pre-deform the scaffold element in the direction "towards the structure" and reduce other deformations that are the result of the action of forces. Worker protection rails located on each scaffold platform can be attached to this type of support. The described support, in addition, provides zero play, even if, as described in more detail below, the self-lifting device in accordance with the invention contains a number of vertical profiles connected to each other. Furthermore, a support of this type can advantageously be used to apply a scaffold element on the inclined parts of a building.
Advantageously, the support between the individual levels of the scaffold element can be adjustable so that it contains a number of connecting points with which it can be connected to a number of levels of the scaffold element. This makes it possible to easily adapt the element of forests and platforms located on it to different heights of the building floors.
The support can be attached, for example, using an eccentric axis. Both with respect to the attachment with the eccentric axis, and with respect to the support described above, it is understood that they show their advantages both by themselves and when interacting with each other, but not necessarily on a lifting device in accordance with the invention. Thus, a support with one or more features described above and / or below, and an eccentric axis, also having one or more features described above or below by themselves, as well as the connection of the support and axis, but without a self-lifting device in accordance with invention should also be construed as the object of the invention.
A self-elevating device in accordance with the invention may ultimately have significant displacement in the vertical direction. In order to simplify the construction of a self-lifting device in its final state, it may contain two or more vertical profiles that are rigidly attached to each other. At the beginning of the lifting process, the self-lifting device can function with one vertical profile. As soon as it is located at the required height above the base, an additional vertical profile can be attached, first in an inclined position, and then, when it is located between the lifting system raised to the required height and the ground, it can be attached in a rigid manner. A vertical profile, divided in this way, can also provide a scaffold element with a “bend” if necessary, for example, in the direction of the structure to ensure compliance with the geometry of the structure.
In addition, for the operation of the self-elevating device, it was considered suitable that the scaffold element contains at least one supporting element for horizontal support of the scaffold element on the structure. A support element of this type makes it possible to release the guide shoe of the scaffold element in such a way that it can be lifted efficiently and reliably.
The invention is described in more detail below with reference to embodiments shown in the drawings, in which:

Figure 6 shows a side view of the guide and
In Fig.7 shows a top view of the guide shown in Fig.6.
The self-elevating device 10, the side view of which is shown in FIG. 1, mainly comprises a scaffold element 12 and a number of drives 18 located along the structure 14, one of these drives 18 is shown in FIG. Figure 1 shows a self-elevating device 10 in the phase in which it is raised by the actuators 18 to create a new section above the currently highest building level. For this, a formwork carriage 30 is provided on the upper part of the scaffold element 12, which can freely move horizontally with one or more formwork 32, a platform 34, various guards 36 and a support 38 for adjusting the formwork. As shown on the left side of FIG. 1, formwork 32 can already be used to create various building levels. Once the concrete has sufficiently hardened at the highest building level, for example, a wall shoe 20.3 can be attached to it, on which a scaffold element 12 is suspended in its upper part. In FIG. 2 shows such a suspended state.
Figure 1 also shows that in the shown example, the element 12 of the scaffold contains two vertical profiles 26.1, 26.2, which can be made as T-shaped or I-shaped profiles. Two vertical profiles 26.1, 26.2 are rigidly attached to each other. In particular, in a state in which the upper vertical profile 26.2 should only be slightly raised above the ground, the lower vertical profile 26.1 must first be rotated into an inclined position and directed away from building 14, and then rigidly attached to the upper vertical profile 26.2 if the latter has been raised sufficiently so that the lower vertical profile 26.1 is vertically between the upper vertical profile 26.2 and the ground.
In the shown example, the support of the upper beam 42, on which the formwork carriage 30 is located, and the lower platform 44 are provided with the support 24.2, which in the shown example is located at an angle or diagonally. As can be seen in the lower part of the support 24.2, it may contain several mounting holes in order to be able to adapt to different distances between the upper beam 42 and the platform 44. In the shown example, the connection to the platform 44 is carried out using the eccentric axis 46. In addition, the support 24.2 may be preloaded. This preloading is usually carried out in the direction of building 14, i.e. in FIG. 1 in a counterclockwise direction, in order to compensate for the weight forces arising from the components in the upper part of the scaffold element 12, which must be transferred to the structure 14 without the risk of significant deformation of the vertical profiles 26 away from the structure. In the example shown, an additional support 24.1 of this type is shown between the platform 44 and the lower platform 48. It is understood that the vertical profiles 26 form a single vertical plane in the region of the scaffold element 12.
The only additional vertical plane is formed by the drive 18. However, as described in more detail below, the drive can be attached to the individual supports 20 on the structure 14 and does not require an additional vertical plane, such as, for example, a vertical profile that can be attached to the building. The drive 18 comprises a lower guide shoe 16.1 and an upper guide shoe 16.2, each of which can be removably connected to the wall shoes 20.1, 20.2, a lifting shoe 50, which provides a connection to the scaffold element 12, a lifting cylinder 52 and a guide rod 54 that protrudes above the lifting shoe 50. In the state shown in FIG. 1, if the drive is attached to the structure 14 and it is necessary to lift the scaffold element 12, the lifting cylinder 52, which rests on the lower wall shoe 20.1 on the structure, extends to raise the element 12 le owls using the connection between the lifting shoe 50 and the element 12 of the scaffold. In the example shown, for this purpose, a number of lifting hooks 22 are provided on the vertical profiles 26 of the scaffold 12. As described in more detail below with reference to FIG. 2, the lifting shoe 50 comprises at least one cam 56 for engaging with the lifting hooks. If the lift cylinder 52 is extended, the guide rod 54 is pushed by the upper guide shoe 16.2 attached to the wall shoe 20.2.
If the scaffold element 12 rises to its final state, in which it is suspended in the upper part on the uppermost wall shoe 20.3, as described in more detail below, the lifting shoe 50 is moved so that the connection with the lower parts of the lifting hooks is lost. The guide rod 54 is attached to the upper guide shoe 16.2 so that the upper guide shoe 16.2 is lifted when the lift cylinder 52 is extended. This also moves the lift shoe to a higher position in which, as described in more detail below, it can rest on the upper side of the lift hook in order to pull the lower guide shoe up while retracting the lifting cylinder 52. Before that, it is disconnected from the wall shoe 20.1 so that the support element 28 pushes the scaffold element away from the structure in the direction of arrow A so that the scaffold element 12 no longer presses on the guide 16.1 in the direction opposite to arrow A. As implied, it can detach from the wall shoe 20.1 and is pulled up when the lifting cylinder 52 is retracted.
Figure 2 shows the lift of the drive 18. As shown in Figure 2, the scaffold element 12 is suspended on the uppermost wall shoe 20.3, and the lift cylinder 52 is in the retracted state in the shown situation. This means that, as shown in more detail in FIG. 4, the lifting shoe 50 rests on the upper part of the lifting hook in order to pull up the lower guide shoe 16.1. After that, the lower guide shoe 16.1 rests on the upper part of the lifting hook and, when the lifting cylinder 52 extends, pushes the lifting shoe 50 further upward so that the lifting shoe 50 can lean on the upper part so that the lower guide shoe 16.1 can be pulled again. These steps are repeated until the upper guide shoe 16.2 can join the upper wall shoe 20.3, and the lower guide shoe 16.1 to the (middle) wall shoe 20.2. This lift of the drive 18 in the second operating mode can be carried out while the next wall section is created using the formwork 32. Once it hardens and the situation becomes basically the same as shown in FIG. 1, the scaffold element can again be raised to a higher position.
FIG. 3 shows in detail the cam 56 of the lifting shoe 50, which in the first operating mode, in which the scaffold element 12 is raised, is subjected to gravity, and thus starting from the position shown in FIG. 3 rotates in the direction of arrow B so that its upper surface 58 can engage with the lower surface 60 of the lifting hook 22 to lift the scaffold element. In the position shown in FIG. 3, in the second operating mode, the cam 56 is preloaded, for example, by means of a spring, so that the upper surface 58 of the cam 56 can pass past the left (in FIG. 3) side of the lifting hook 22 to move the lifting shoe 50 upward when lifting the drive. If, as shown in FIG. 3, the lower part of the cam enters the area of the lifting hook 22, then it rotates slightly opposite the compression force of the spring in the direction of arrow B in order to be able to pass the lifting hook.
Figure 4 shows how, when lifting the actuator 18, support is provided on the upper flat sides of the lifting hooks 22. For this, a so-called locking dog 60 is provided, which, in accordance with the image in Figure 4, is prestressed by a spring to the left side, and which in the example shown contains a bevel that is located from the lower left to the upper right. This bevel can be used to deflect the locking dog 60 to the right, opposite the compression force of the spring, when the lifting shoe 50 moves upward and the locking dog 60 clamps the lifting hook. When the lift cylinder 52 extends, the lower part of the locking dog 60 is engaged with the upper part of the lift hook in order to pull the lower guide shoe 16.1 (see FIGS. 1 and 2) by retracting the lift cylinder 52.
FIG. 5 shows an alternative embodiment that differs from the actuator in the embodiment shown in FIGS. 1-4 in that the actuator 18 is not connected to the lower guide shoe 16.1, but rests directly on the wall shoe 20. In this embodiment the lower guide shoe 16.1 also has a design different from that shown in FIGS. 1-4, and will be discussed in more detail with reference to FIGS. 6 and 7. With respect to the drive 18, it should be noted that its support on the wall shoe 20 is located at a relatively large distance The position of the actuator 18 in the area remote from the vertical profile 26 causes gravity to act on the actuator 18 so that it "automatically" tilts toward the vertical profile 26, and thereby reliable engagement is guaranteed. At the same time, the support 62 prevents the drive 18 from shifting to the right of the vertical profile. In this case, the lifting hooks 22 are designed so that their lower sides contain the connecting recesses 64, and their upper sides contain the grooves 66. The connecting recesses 64 engage with the support bolt 68 on the lifting shoe 50 of the drive 18 to lift the scaffold using the vertical profile 26 The support bolt 68 is engaged with the grooves 66 on the upper side in order to pull the actuator 18 up in the second operating mode. In the embodiment shown in FIG. 5, it is possible to disconnect the actuator 18 and manually move it to a higher part.
Figures 6 and 7 show an alternative embodiment of the guide shoe 16. It is for the most part rotationally connected using a clamp bolt 70, which may include a clamp 72 and a fastening device in the form of a wire rope 74, to a wall shoe 20, which is fixed to the structure using anchor 76. A spring or rubber damper 78 holds the guide shoe 16 in a rotational manner attached to the wall shoe 20 in a suitable position. In the embodiment shown in FIG. 6, the guide shoe 16 does not contain cams, as in the case of the embodiment shown in FIGS. 1-4, but in the example shown, it contains two support bolts 80.1, 80.2 that can be moved in respective guide circuits 82.2 and 82.1. In FIG. 6 shows an embodiment in which the guide shoe 16 is engaged with the lift hook 22 for lifting the scaffold member above the vertical profile 26. However, if the guide shoe 16 is inactive when the vertical profile 26 is raised above the guide shoe 16, the lift hook 22 moves from the bottom in the direction support bolt 80 and deflects it with its beveled surface 84 (see Fig. 5) in order to be able to pass by the support bolt 80. For this, the guide circuit 82 is made relatively flat in its lower part and (the right part in FIG. 6) in order to facilitate this deviation. In the upper part (the left part in FIG. 6), the guide loop 82 is made relatively inclined in order to ensure that, by gravity, the support bolt 80 reliably returns to the position shown in FIG. 6, in which it is possible to engage with the lifting hook 22 for lifting the scaffold element.
In the embodiment shown in FIG. 6, two substantially the same support bolts 80 are provided, which are guided by respective guide circuits 82 to reduce separation. The fact that the distance between the two support bolts 80 is less than the distance between two adjacent lifting hooks (only one of which is shown in FIG. 6) means that either the upper or lower supporting bolt can engage with the corresponding lifting hook and make the mesh in which meshing is possible more frequent.
FIG. 6 also shows a guide gripper 86 rotatably attached to the guide shoe 16. As is more clearly shown in FIG. 7, it is attached to the back of a specific portion of the I-shaped section, which, as shown in FIG. 6, is located perpendicular to the projection plane. In the embodiment shown in FIG. 6, the vertical profile 26 is supported in the direction away from the guide shoe 16, that is, to the right in FIG. 6, with the guide catch 86. Since it can be rotated relative to the guide shoe 16, this support not at a single point (shown in cross section), but along a line. In a three-dimensional representation, this means a flat support, which has the advantage that it does not have highly loaded points.
As shown in FIG. 7, the rotating attachment of the guide grippers 86.1, 86.2 can also be used to bend them back from the vertical profile 26 to detach the entire guide shoe from the vertical profile. For this, as shown in Fig. 7, for the left (in accordance with the image in Fig. 7 top) guide grab 86.1, it is first (in the first operating position) pushed horizontally, in the left direction, upward, according to Fig. 7, and then bent back in the direction of arrow C. The fact that the distance between the axis 88 around which the rotation is carried out and the front edge (right edge in accordance with FIG. 7) of the guide grasp 86 is less than the distance between the axis of rotation 88 and the bolt 70, which together with guide 16 attached to the wall shoe 20 makes it possible to avoid blocking of the bolt 70 with the help of the bent back grips 86. Thus, only that part of the axis 88 that is removed from the guide shoe 16 can be made in this way, for example, with a circular cross section that would ensure the described rotating traffic. Despite this, the areas closer to the guide shoe 16 can be made in angular shapes, for example, in the form of a square or another polygon in order to prevent the guide grips 86 from turning in this area in the closed position.
Obviously, the details of all embodiments can be combined with each other. For example, the elevator shoe 50 shown in FIG. 5 may also be provided with support bolts in accordance with FIG. 6 and 7, and the drive in accordance with FIG. 5 may be supported or attached to the lower lift shoe 16.1 instead of the wall shoe 20. Similarly, the lift shoe shown in FIGS. 6 and 7 can be used with any of the embodiments shown in FIGS. 1-5.
