Description

  The present invention relates to a guide shoe and a lifting system for use in the construction field. In the building field, it is known that autonomous lifting systems are used in particular for constructing multi-story buildings, preferably high-rise buildings. Such a self-elevating system includes the formwork necessary to build the vertical wall of the building. As soon as the newly constructed wall is fully cured, the lifting drive is supported on the wall by a suitable cross section, so that the so-called scaffold unit is raised and lowered, thereby driving it up and down The vertical wall can be further “grown” in the area where the device and wall overlap. While the wall is built, the scaffold unit drive “follows” upwards, so as soon as the newly constructed section is fully cured, the scaffold unit can be lifted from the newly constructed section it can.

  Such an autonomous lifting system is disclosed in US Pat. No. 4,962,828. In this patent document, the scaffold unit does not necessarily have a formwork, but for example comprises a safety net and / or scaffold projecting outward from a building structure including the floor to be built inside itself. Yes. Scaffolding is provided in the scaffolding unit. Additional profiles are attached to individual points of the building structure. Also, a switchable drive is provided to raise any of the components provided for fixing to the scaffold unit or building structure.

  There is known a form lifting system designed by SKE in which vertical components supporting a drive for raising a scaffold unit are fixed to a building structure. In an alternative operating position, the drive is supported by a scaffold unit. At this time, the scaffold unit is suspended and / or locked on the building structure in order to lift the vertical component into the new compartment.

  An object of the present invention is to provide a guide shoe and an elevating system for use in the construction field, and improve the efficiency of construction.

  The object of the present invention is achieved by a guide shoe according to claim 1 and an elevating system including the guide shoe. In the further claims preferred developments are disclosed.

  A guide shoe, hereinafter also referred to as a guide in the present specification, includes at least one guide jaw member that is movable in the horizontal direction and rotatable about a horizontal axis. The shoe can be disengaged from the scaffold unit of the lifting system. The guide jaw member includes, for example, a T-shaped cross section, an I-shaped cross section, a U-shaped cross section, or a member having a part of one of these cross sections. For example, the cross section of at least a vertical member (a member extending in the vertical direction) provided in the scaffold unit is a T-shaped cross section or an I-shaped cross section. The rim of the scaffold unit having a T-shaped cross section and extending in the horizontal direction extends parallel to the outer surface of the building structure and toward the building structure. In this case, the guide jaw member is pulled so as to be disengaged by holding the rim and moving horizontally, and is removed by rotating about the substantially horizontal axis. A further advantage of the pivotal attachment that attaches at least one guide jaw member to the guide shoe is that it can prevent load distribution when the guide shoe is pivotally attached to the attachment of the building structure. is there. That is, as will be described below with reference to the drawings, when the scaffold unit is suspended on the guide shoe, the guide shoe is independently arranged (when viewed in a sectional view) or (when viewed in a perspective view). High stress occurs when tilted so as to be arranged along the vertical member. This is avoided by a guide jaw member rotatably provided on the guide shoe.

  The guide shoe is provided in the lifting drive of the lifting system. Furthermore, the guide shoe is attached to a wall-side shoe attached to the building structure and / or the lifting system is guided by the guide shoe.

  It is further desirable that a gap be formed between the pivot shaft serving as the center when the guide jaw member rotates and the outer end of the guide jaw member to be smaller than the distance between the pivot shaft and the fixing device. . The fixing device is provided between the guide shoe and the wall shoe. This prevents the fixing device between the guide shoe and the wall-side shoe from obstructing the turning of the guide jaw member.

  Accordingly, such a guide shoe can effectively attach the lifting drive directly to the guide shoe of the building structure and / or the scaffold unit. Attaching the guide shoe directly to the scaffold unit is particularly advantageous when the scaffold unit is raised. Furthermore, the guide shoe has the following advantages either alone or in combination with further features. Two pawls or bearing bolts are provided on each guide shoe as described below. The guide shoe is rotatably attached to the shoe on the wall side. Aligning the rotary mount with a spring or other elastic element, such as a rubber bumper, for planar support of the guide shoe as described in further detail below. As described in detail below with reference to FIG. 7, following axial movement, the guide pawls or guide jaw members are non-rotated in some areas, for example by a square or other rectangular shape, and some In order to make the guide jaw member pivotable in the region of (2), it is guided on the guide shoe so as to be rotatable.

  The lifting system herein is preferably a self-lifting system as described below, but comprises at least one scaffold unit guided and / or suspended by at least one guide on the building structure side. . The scaffolding unit is equipped with the work platform, the formwork, and the objects required for work in the scaffolding unit. With respect to the scaffold unit, it should be noted that the present invention need only include the support member in a plane. In order to keep the forces and torques caused by normal forces acting on the building structure, even if additional support members are provided, the only plane is provided with support members and is provided in the vicinity of the building structure. As such, the scaffold unit can be of a particularly simple and easy construction. A guide capable of guiding and / or suspending the scaffold unit is a wall shoe attached to a building structure. In particular, the scaffold unit is preferably configured to be suspended in the upper region of the building structure. In the lower region, a guide is provided on a so-called guide shoe. The guide shoe is attached to, for example, a further shoe on the wall side, and has a configuration of an elevating drive device described below.

  In the present invention, the self-elevating system includes at least one elevating drive device that can be directly attached to each of the attachment portions on the building structure side. Advantageously, the drive device forms a single further second vertical surface in addition to the vertical surface of the support member of the scaffold unit. In particular, the drive device has no elements extending parallel to each other in the ascending direction. If the drive is mounted directly on the building structure, for example by one or more guide shoes mounted on the shoe on the wall side of the building, no further vertical members are required as in the prior art. The self-elevating system according to the present invention is particularly simple. For example, only a mounting part such as a shoe on the wall side is provided in the building structure. The only thing located between these attachments and the scaffold unit is the drive. The drive device includes a guide shoe optionally provided without the need for a further vertical surface. Thereby, a self-elevating system is easily configured.

  Further, the elevating drive device can be detachably attached to the building structure, and can be switched between a first operation mode in which the scaffold unit is raised and a second operation mode in which the elevating drive device is raised. In conclusion, an ideal lifting and lowering can be achieved efficiently without the need for a crane to raise the scaffold unit or drive. In this connection, only the lifting and lowering drive device operates in the first operation mode between the mounting portion provided on the building structure and the scaffold unit. On the other hand, in the second operation mode, the lifting drive is disassembled and lifted to a higher area by the operator. In this case, an advantage of the present invention is that the drive is small and light enough to allow the operator to perform this process with reasonable effort.

  It should be noted that the self-lifting system shows advantages in the absence of a guide shoe and takes into account the problems to be solved in this application accordingly. This is true for any embodiment of a self-elevating system having one or more of the features described above and / or below.

  It should be noted that it is advantageous to use a protruding lifting cam to engage the lifting drive and the scaffold unit. Such a lifting cam has a simple configuration and provides an area that needs to be supported between each lifting operation. However, it should be noted that the present invention can be practiced with recesses, perforated member openings, rack gear protrusions and other engagement means such as other means.

  Furthermore, it is desirable that at least one guide can be disengaged from the scaffold unit. This is advantageous in that the lifting drive can be separated from the scaffold unit and can be moved to a higher area. This makes it easy to implement a so-called partial hydraulic operating mode. In this mode of operation, only the lift drive is operable when the scaffold unit is raised. Furthermore, since the lifting drive can be removed, it is desirable to combine it with an operation in which the crane raises the scaffold unit at least partially. In this context, disengaging the guide from the scaffold unit allows the drive device to be removed from the scaffold unit when the scaffold unit extends with one or more members in the area of the guide. Needless to say. The above treatment means that the lifting drive must be removable while waiting for the scaffold unit to rise to a position sufficiently higher than the area of the guide. Thereafter, the guide is removed from the mounting portion of the building structure, for example, the shoe on the wall side.

  Preferably, the components of the lifting drive apply a lifting force to the scaffold unit and utilize at least one pawl and / or at least one bearing bolt. Preferably, the pawl or bearing bolt is subjected to gravity in the first operating mode and is subjected to a spring force in the second operating mode. The pawl or bearing bolt receives spring force in the first mode of operation, receives gravity in the second mode of operation, receives gravity in both modes of operation, or receives spring force.

  In this connection, it is further advantageous if at least two pawls or bearing bolts are arranged in the lifting direction on the lifting drive. This is advantageous because the "stage" can be further subdivided when the scaffold unit or the lift drive device is raised or lowered. This adjustment interval, for example the distance between the climbing cams, is initially defined by the engagement member of the scaffold unit. However, if two or more pawls or bearing bolts are arranged on the guide, optionally one pawl or the other pawl, or one bearing bolt or the other bearing bolt will be “division” It is possible to engage with a specific lifting cam in that it is finer. For example, the distance between the lifting cams 22 in each case is 300 mm, and the distance between the two bearing bolts 80 is 150 mm, so the overall adjustment interval is 150 mm. Furthermore, the pawls and / or bearing bolts are provided for the first operating mode or the second operating mode.

  In the case of bearing bolts, it is advantageous to have at least one guide contour with one lower flat section and / or one upper inclined section. By means of the upper inclined section, the bearing bolt that receives the gravity becomes available, and in this region, it descends rapidly due to the inclined section of the curved guide part. Advantageously, as detailed below with reference to the drawings, when the bearing bolt is bent at least temporarily, the lifting cam of the scaffold unit must pass in the vicinity of the bearing bolt, The bearing bolt is easily bent by the lower flat region.

  In principle, a single pawl or a single bearing bolt can be configured to be able to carry out both modes of operation in each case. However, the at least one locking claw is provided so that the first operating mode is locked and the second operating mode is to “pull up” the lifting drive to the vicinity of the support by the locking claw of the scaffold unit. It is desirable that

  In order to ensure driving safety, it is further desirable that at least one ascending drive is held and / or arranged by gravity towards the mounting and / or scaffold unit.

  With regard to the construction of the scaffold unit, it is further desirable that the scaffold unit configure and / or generate significant weight that is transmitted through the building structure. In conclusion, the forces due to weight and other forces acting at a predetermined distance on the building structure cause the scaffold unit to deform “so as to be spaced away from the building structure”. Therefore, it is preferable that the scaffold unit is provided with at least one prestressed support in a region separated from the building structure. This support can prestress the scaffold unit “towards the scaffold unit” and reduce other deformations caused thereby. Rails are disposed on each scaffold of the scaffold unit and attached to the support to protect the operator. As described in further detail below, the support can further eliminate backlash even when the self-elevating system according to the present invention includes a plurality of vertical members connected to each other. Furthermore, the support can be used to adapt the scaffold unit to the sloped part of the building in a significant way.

  In an advantageous manner, the support provided between each level of the scaffold unit is provided with a plurality of fixing points attached to a plurality of levels of the scaffold unit so that it can be adjusted by these fixing points. This allows the scaffold unit, level, and scaffolding provided at the level to be easily adapted to various floors within the building structure.

  For example, the support can be fixed by an eccentric spindle. It should be noted that both the eccentric spindle and the support have advantages within the scope of the right and are combined with each other, but are not necessarily required for the self-lifting system of the present invention. Accordingly, a support having one or more of the above features and / or the following features, an arrangement of eccentric spindles belonging to the scope of rights and having one or more of the above or below features, and a combination of the support and the eccentric spindle are provided by the present invention. It should be noted that this is the subject of the present application, except for a self-lifting system that can be installed.

  The self-elevating system according to the invention has a considerable extension in the vertical member in the final state. In order to simplify the configuration of the self-elevating system in the final state, the self-elevating system comprises two or more vertical members rigidly connected to each other. When the lifting process is initiated, the self-lifting system is enabled with a single vertical member. As soon as the self-elevating system is located at a predetermined height above the foundation, a further vertical member is first installed in a tilted arrangement and then the self-elevating system with the vertical member raised to a predetermined height and the ground. Firmly connected when positioned between. If necessary, the vertical unit divided in this way allows the scaffold unit to be provided with “kinks”, for example towards the building structure, in order to accommodate the structural contours.

  In order to operate the self-elevating system, the self-elevating system is further advantageous if the scaffold unit comprises at least one support unit for horizontally supporting the scaffold unit engaged with the building structure. .

  The invention will be described in detail with reference to the embodiments represented in the drawings.

  FIG. 1 is a side view of the self-elevating system 10. The self-elevating system includes a scaffold unit 12 and a plurality of driving devices 18 provided along the building structure 14. FIG. 1 shows one drive unit 18 among a plurality of drive units provided along a building structure. FIG. 1 represents a self-elevating system 10 raised by a drive 18 to form a further compartment above the currently highest construction part. For this purpose, a formwork carriage 30 comprising one or more formwork 32, a platform 34, various rails 36 and a support 38 for adjusting the formwork and movable in the horizontal direction over a wide range is provided as a scaffold. It is provided in the highest region of the unit 12. As shown in the left region of FIG. 1, the formwork 32 has already been used to form different construction parts. When the concrete of the highest construction part is sufficiently hardened, immediately, for example, the shoe 20.3 on the wall side in which the scaffold unit 12 is suspended in the upper region is locked in the upper region. FIG. 2 shows such a locked state.

  As shown in FIG. 1, the scaffold unit 12 includes two vertical cross-section members 26.1 and 26.2 having, for example, a T-shaped cross section and an I-shaped cross section. The two vertical cross-section members 26.1, 26.2 are firmly connected to each other. In particular, when only the upper vertical section member 26.2 has to be raised slightly from the reference plane, the lower vertical section member 26.1 initially extends away from the building structure 14. And then the upper vertical cross-section member 26.2 is sufficiently raised so that the lower vertical cross-section member 26.1 is brought into contact with the upper vertical cross-section member 26.2 and the reference plane. The lower vertical cross-section member 26.1 is firmly connected to the upper vertical cross-section member 26.2 when vertically aligned between them.

  In this embodiment, the support for the upper beam 42 is provided with a formwork carriage 30, and the support 24.2 tilted or diagonally aligned is provided with a lower platform 44. A number of fixing holes are provided in the lower region of the support 24.2 to accommodate various distances between the upper beam 42 and the platform 44. In this embodiment, the support is fixed to the platform 44 by an eccentric spindle 46. Furthermore, support 24.2 may be prestressed. This pre-stress treatment is generally performed toward the building structure 14, that is, counterclockwise in FIG. 1, so that the scaffold unit 12 that needs to move to the building structure 14 without largely deforming the vertical cross-section member 26 is used. The load caused by the components provided in the upper region can be offset. In this embodiment, further support 24.1 is provided between the platform 44 and the lower platform 48. It should be noted that the vertical cross-section member 26 forms a unique vertical plane within the region of the scaffold unit 12.

  Only one additional vertical plane is formed by the drive 18. However, as will be described in detail below, the drive is attached to an independent mounting 20 of the building structure 14 and requires an additional vertical plane such as a vertical cross-section member attached to the building structure. do not do. The drive device 18 is for lifting and lowering engaged with the scaffold unit 12 with the lower guide shoe 16.1 and the upper guide shoe 16.2 removably attached to the shoe 20.1, 20.2 on the wall side. A shoe 50, a lifting cylinder 52, and a guide rod 54 extending above the lifting shoe 50 are provided. In the state of FIG. 1, when the drive device is locked to the building structure 14 and the scaffold unit 12 is raised, the lifting supported by the shoe 20.1 on the lower wall side of the building structure. Since the cylinder 52 extends, the scaffold unit 12 can be lifted by the engagement of the lifting shoe 50 and the scaffold unit 12. For this purpose, in this embodiment, a plurality of lifting cams 22 are provided on the vertical cross-section member 26 of the scaffold unit 12. As described in detail below with reference to FIG. 2, the lifting shoe 50 includes at least one claw 56 for engaging with the lifting cam. When the lifting cylinder 52 extends, the guide rod 54 is pressed by the upper guide shoe 16.2 attached to the shoe 20.2 on the wall side.

  When the scaffold unit 12 is in a final state, that is, when the scaffold unit is suspended in the upper region of the shoe 20.3 on the wall side provided at the highest position, as described in detail below. Are rearranged so that the lifting shoe 50 does not engage the lower side of the lifting cam. Since the guide rod 54 is attached to the upper guide shoe 16.2, the upper guide shoe 16.2 is raised when the lifting cylinder 52 is extended. As a result, when the lifting shoe 50 is located at a higher position, that is, as described in detail below, the lifting shoe 50 is placed on the upper side of the lifting cam in order to pull up the lower guide shoe when the lifting cylinder 52 is contracted. Move to a supported position. The lower guide shoe is released from the wall-side shoe 20.1. That is, since the support unit 28 pushes the scaffold unit away from the building structure in the direction of arrow A, the scaffold unit 12 cannot push the lower guide shoe 16.1 in the direction opposite to arrow A. As described above, the lower guide shoe is released from the wall-side shoe 20.1 and pulled up when the lifting cylinder 52 contracts.

  FIG. 2 shows the ascending process of the driving device 18. As shown in FIG. 2, the scaffold unit 12 engages with the shoe 20.3 on the wall side provided at the highest position, and the lifting cylinder 52 is in a contracted state. This means that the lifting shoe 50 is supported on the upper side of the lifting cam, as shown in detail in FIG. 4, so that the lower guide shoe 16.1 can be pulled up. After that, the lower guide shoe 16.1 is supported on the upper side of the lifting cam, and the lifting shoe 50 is further pushed up by the extension of the lifting cylinder, so that the lifting guide 50 is supported in the upper region. Thereafter, the lower guide shoe 16.1 is lifted again. These processes until the upper guide shoe 16.2 engages the upper wall-side shoe 20.3 and the lower guide shoe 16.1 engages the (middle) wall-side shoe 20.2. Is repeated. The drive device 18 is raised as described above in the second operation mode, and a wall section is further formed in the upper region by the mold 32. As soon as the formwork hardens and the situation is similar to FIG. 1, the scaffold unit rises again towards the higher section.

  FIG. 3 is a detailed view of the claw 56 of the lifting shoe 50. In the first operation mode in which the scaffold unit 12 is raised, the claw rotates in the direction of arrow B from the position of FIG. 3 due to the influence of gravity, so that the upper surface 58 is engaged with the lower side 60 of the lifting cam 22. As a result, the scaffold unit can be raised. In the position of FIG. 3, in the second operation mode, the claw 56 is prestressed by, for example, a spring, so that the upper surface 58 of the claw 56 passes near the left side surface of the lifting cam 22 in FIG. When the device is raised, the lifting shoe 50 can be moved upward. When the lower region of the claw enters the region of the lifting cam 22 as shown in FIG. 3, it slightly turns against the spring force acting in the direction of the arrow B, thereby passing the vicinity of the lifting cam. it can.

  FIG. 4 shows a mode in which the drive device 18 is supported on the flat upper side of the lift cam 22 when the drive device 18 is lifted. In order to provide such support, the so-called lock claw 60 is prestressed toward the left side of FIG. 4 by a spring, and in this embodiment, has an inclined surface extending from the lower left side to the upper right side of FIG. When the lifting shoe 50 is moved upward and the locking claw 60 strikes the lifting cam, this inclined surface is used to deflect the locking claw 60 to the right against the spring force. When the lifting cylinder 52 is extended, the lower side of the lock claw 60 engages with the upper side of the lifting cam and offsets the weight of the lifting cylinder 52, so that the lifting shoe 52 is followed (FIGS. 1 and 2). The lower guide shoe 16.1 can be lifted.

  FIG. 5 shows the drive device of the embodiment shown in FIGS. 1 to 4 in that the drive device 18 is not attached to the lower guide shoe 16.1, but is directly supported by the shoe 20 on the wall side. Fig. 4 represents an alternative embodiment with a different drive. The configuration of the lower guide shoe 16.1 in this embodiment is different from the configuration of the guide shoe shown in FIGS. 1 to 4, and will be described in detail below with reference to FIGS. It should be noted that the support of the driving device 18 on the wall-side shoe 20 is arranged at a relatively large distance from the vertical cross-section member 26 provided with the lifting cam 22. By supporting the drive device 18 in a region separated from the vertical cross-section member 26, gravity acts on the drive device 18, and the drive device is "automatically" tilted toward the vertical cross-section member 26. Secure engagement. At the same time, the driving device 18 is not released to the right side from the vertical cross-section member by the mounting portion 62. In this embodiment, an engagement slot 64 is formed on the lower side of the elevating cam 22, and a notch 66 is formed on the upper side of the elevating cam. Since the engagement slot 64 is engaged with the lifting shoe 50 of the driving device 18 by the bearing bolt 68, the scaffold unit can be raised by the vertical cross-section member 26. The bearing bolt 68 engages with the notch 66 on the upper side of the lifting cam, thereby pulling up the driving device 18 in the second operation mode. In the embodiment depicted in FIG. 5, it goes without saying that the drive 18 can be removed and the drive can be manually transported to a higher compartment.

  6 and 7 represent an alternative embodiment of the guide shoe 16. This guide shoe is rotatably attached by a lock bolt 70. The lock bolt includes a clip 72 and a fixing device for the shoe 20 on the wall side in the form of a wire rope 74. The shoe on the wall side is locked by an anchor 76 provided in the building structure. A spring or rubber damper 78 holds the guide shoe 16 rotatably attached to the wall-side shoe 20 in an appropriate position. In the embodiment shown in FIG. 6, the guide shoe 16 does not include the claw in the embodiment shown in FIGS. 1 to 4, but in the illustrated case, the guide shoe 16 is within the curve guide portions 82.1 and 82.2 (guide contour). It is provided with two bearing bolts 80.1 and 80.2 that can be moved at the same time. FIG. 6 represents a guide shoe 16 that can engage the lifting cam 22 and thereby raise the scaffold unit over the vertical cross-section member 26. However, if the guide shoe 16 is not functioning when the vertical cross-section member 26 is lifted beyond the guide shoe 16, the elevating cam 22 moves from below toward the bearing bolt 80, and the inclined surface 84 ( The bearing bolt can be deflected together with the bearing bolt 80, as shown in FIG. For this reason, the curve guide portion 82 is relatively flat in the lower region (the right region in FIG. 6) for easy deflection. In the upper region (the left region in FIG. 6), the curved guide portion 82 is relatively steep in order to reliably return the bearing bolt 80 to the position shown in FIG. 6 by the action of gravity. In FIG. 6, the bearing bolt is engageable with the lifting cam 22 to raise the scaffold unit.

  In the embodiment shown in FIG. 6, two substantially identical bearing bolts 80 guided in each curve guide portion 82 are provided so as to reduce the adjustment interval. That the distance between two bearing bolts 80 is smaller than the distance between two adjacent lifting cams (only one lifting cam is shown in FIG. 6) means that the upper bearing bolt or the lower bearing bolt It means that either one can be engaged with each raising / lowering cam, and the interval in which the engagement can be made can be reduced.

  In FIG. 6, the guide jaw member 86 is rotatably attached to the guide shoe 16. As clearly shown in FIG. 7, this guide jaw member is engaged from the rear with an I-shaped cross-sectional arm extending perpendicularly to the projection plane as shown in FIG. In the case shown in FIG. 6, the vertical cross-section member 26 is supported on the guide jaw member in a direction away from the guide shoe 16, that is, toward the right side of FIG. 6. Since this guide jaw member is rotatable relative to the guide shoe 16, it can be supported along a predetermined line rather than on individual points (shown in a cross-sectional view). From a three-dimensional perspective, this means constant support that is effective to avoid high point loads.

  As shown in FIG. 7, since the guide jaw members 86.1 and 86.2 are pivotally attached, these guide jaw members can be folded back from the vertical cross-section member 26, thereby the entire guide shoe 16 is removed. The engagement can be released from the vertical cross-section member. For this purpose, like the left (upper side in FIG. 7) guide jaw member 86.1 shown in FIG. 7, the guide jaw member is initially horizontal (in the operable position) horizontally towards the left side, ie upward in FIG. Pushed and then folded in the direction of arrow C. In a state in which the guide shoe 16 is fixed to the shoe 20 on the wall side, the distance between the pivot shaft 88 whose pivot is the guide jaw member and the front edge (right edge portion in FIG. 7) of the guide jaw member 86 is the pivot axis. Since the distance between 88 and the lock bolt 70 that fixes the guide shoe 16 to the shoe 20 on the wall side is smaller, the lock bolt 70 does not hinder the bending of the guide jaw member 86. Thereby, only the area | region of the turning shaft 88 spaced apart from the guide shoe 16 can perform the above-mentioned turning motion by rounding a cross section, for example. On the other hand, in the region in the vicinity of the guide shoe 16, for example, the cross section is formed in a shape such as a square shape or other polygonal shape so that the guide jaw member 86 in the region is turned in a closed state. Can be prevented.

  Details of all the embodiments can be understood by combining the embodiments. For example, the lifting shoe 50 shown in FIG. 5 is suspended or attached to the lower lifting shoe 16.1 instead of the wall-side shoe 20. Similarly, the lifting shoes shown in FIGS. 6 and 7 can be used in all of the embodiments shown in FIGS.
