[0001] Climbing shoe, ratchet device, fastening part and method

[0002] Description

[0003] The invention relates to a climbing shoe for a construction aid, a latch device and a fastening part for a climbing shoe as well as a method for producing at least one section of a concrete component.

[0004] A construction aid is a tool used for the construction of structures. Examples of structures include buildings, bridges, or walls. Cranes, scaffolding, and formwork are used to erect such structures. With such construction aids, there may be a risk that people and objects such as tools, bolts, screws, debris, etc. could fall from great heights. To prevent these risks, construction aids may be equipped with protective devices to prevent falling. Protective devices can include railings, gratings, nets, walls, etc.

[0005] A formwork is a mold. Fresh concrete can be poured into the mold. After the concrete has hardened, the formwork can usually be removed. This can be used to create components for buildings or bridges, for example. Examples of components include walls, ceilings, shafts, and columns.

[0006] A formwork can be formed from a plurality of formwork panels. A formwork panel is a panel made of wood or plastic, for example. A formwork panel can be flat and / or curved at least in certain areas. Supporting elements, such as a frame, longitudinal beams, and / or cross beams, can be present on the back of the panel. The supporting elements can be made of wood or steel, for example. A front side of the formwork panel contacts and limits the poured concrete, thus forming the surface of the component.

[0007] A formwork panel frame generally does not protrude beyond the front of the panel. A formwork panel can have one or more anchor holes. An anchor can be inserted through opposing anchor holes in two opposing formwork panels. The ends of an anchor can be secured in such a way that the anchor can then no longer be pulled out of the anchor holes. The two ends of an anchor can be attached to the backs of formwork panels, for example, in such a way that an anchor can absorb at least compressive forces, and preferably also tensile forces. Two opposing formwork panels can be connected to one another using one or more anchors.

[0008] An example of a construction aid is a climbing scaffold. A climbing scaffold can be attached to an already completed section of a building. A part of the climbing scaffold, for example a climbing rail, can be moved upwards and then held in place, in particular by means of at least one climbing shoe. After completion of a concreting section, at least part of the construction aid, in particular the entire construction aid, can be pushed upwards to prepare for a subsequent concreting section. Likewise, at least part of the construction aid, in particular the entire construction aid, can be lifted upwards or moved in some other way. The pushing, lifting, or moving is carried out using a suitable pushing device, for example hydraulically driven. This means that no crane is required. It is also possible to climb downwards, for example to demolish at least part of a building or component.Here, a downward pushing and / or a downward movement due to gravity can occur.

[0009] A platform can be attached to the climbing frame, which can be moved to a desired height. The platform can be walkable. One or more formwork panels can be installed on or above the platform, or independently of the platform, to form a formwork. A safety device can be attached to the platform to prevent falling. A climbing frame with additional components attached, such as a platform, formwork panel, and / or safety device, is called a climbing system.

[0010] A climbing rail is an elongated, substantially vertically oriented element which is pushed upwards relative to the climbing shoe. When climbing downwards, the climbing rail moves downwards relative to the climbing shoe. A climbing rail can, for example, have one or two or more vertical supports and / or a plurality of support elements arranged at right angles thereto, such as bolts or struts. The support elements are substantially horizontally oriented. The latch device can be configured to hold at least one support element. A climbing shoe is used to hold the construction aid, e.g. the climbing scaffold, to the manufactured component. A climbing shoe is attached to a manufactured component made of concrete, typically to a completed concreting section, preferably by means of at least one screw.In particular, a climbing shoe enables an upward movement of the construction aid. For this purpose, a climbing shoe typically contains a mechanism that allows the construction aid to be moved upwards and / or that allows the construction aid to be held in different positions. A climbing shoe then holds the construction aid in the upwardly pushed position after it has been moved. Typically, each climbing rail is held with at least two climbing shoes that are arranged at different heights, preferably one above the other. If a climbing shoe is no longer required, for example because the lowest climbing shoe is positioned too low to hold the upwardly pushed construction aid, it is removed from the manufactured component and reattached, in particular, at a higher position. The climbing shoe can then be used for a subsequent concreting section.

[0011] The above-mentioned features, effects and definitions may be combined individually or in a plurality with the claimed and described subject-matter.

[0012] Because a climbing shoe incorporates the aforementioned mechanism, it is typically heavy. To enable manual removal, transport, and attachment, a two-part construction is known in which two lighter parts can be removed, transported, and attached separately. Document EP 1 899 548 B1 discloses such a climbing shoe comprising a wall shoe part for attachment to a vertical wall and a sliding shoe part with claws for gripping a climbing rail and a latch for supporting the climbing rail. The wall shoe part and sliding shoe part are detachably connected to one another by means of a plug-in shaft. This results in complex coupling and detachment and limited flexibility in the use of the climbing shoe.

[0013] The object of the invention is to provide an advanced climbing shoe, an associated latch device, an associated fastening part, and a method that, in particular, enable more flexible and safe use. This object is achieved by the climbing shoe according to claim 1 and the latch device, the fastening part, and the method according to the independent claims. Advantageous embodiments are specified in the subclaims.

[0014] To achieve this objective, a climbing shoe for a construction aid serves. The climbing shoe comprises a fastening part with a fastening section for fastening to a manufactured concrete component and with at least one guide claw for gripping the construction aid. The climbing shoe further comprises a latch device that can be releasably connected to the fastening part for holding the construction aid.

[0015] The latch device can be detachably connected to the fastening part, particularly manually. For example, the latch device can be inserted into a cavity in the fastening part. At least one guide claw is present. The fastening part with the fastening section and the guide claw can thus remain attached to the manufactured component while the latch device is released and removed. Releasing the latch device has no effect on the attachment of the guide claw. In particular, the latch device can be released and / or removed while the construction aid is gripped by the guide claw.

[0016] One advantage of the invention is that the latching device only needs to be present on those climbing shoes where it is actually required. The latching device basically serves to introduce vertical forces from the construction aid into the manufactured component. In order to reduce the load on the component, which is usually not yet fully cured, vertical forces and horizontal forces are usually introduced into the component at separate positions, namely using separate climbing shoes. Typically, vertical forces are introduced at a lower climbing shoe and / or horizontal forces are introduced at an upper climbing shoe. In this case, the latching device is only required on the lower climbing shoes. This means that significantly fewer latching devices are required, which reduces the technical effort on site as well as the manufacturing costs.

[0017] In this context, the invention also eliminates a source of error on the construction site. Because each climbing shoe has previously been equipped with a latch device, it can happen that a climbing shoe is mistakenly used to introduce vertical and horizontal forces. This can overload the climbing shoe and / or exceed the load-bearing capacity of the not yet fully cured concrete. According to the invention, the vertical force can only be introduced at climbing shoes that include a latch device. Therefore, only as many latch devices are provided as there are climbing rails. This effectively prevents the vertical force from being introduced at a climbing shoe that is not intended for this purpose. The load transfer is easily visible.

[0018] The divisibility also allows for separate transport of the fastening component and the latching device on the construction site, thus minimizing the weight to be carried. In particular, the fastening component and / or the latching device weigh no more than 25 kg. This facilitates transport on the construction site and ensures improved occupational safety.

[0019] The fastening part is used to attach the climbing shoe to the manufactured concrete component. Typically, it is screwed to the component. The fastening part carries the construction aid and thus fastens the construction aid to the component. Likewise, the fastening part and / or the fastening section can be designed for attachment to a component made of a different material. For example, the climbing shoe can be used for the construction or demolition of a steel structure. The fastening part can be designed, for example, as a wall anchoring element or as a ceiling anchoring element. A latch device can therefore be combined with fastening parts of different designs.

[0020] The fastening section serves to fasten the climbing shoe to the manufactured component. The fastening to the component can comprise or be a direct fastening, in which the fastening section is connected directly to the component, e.g. by means of a screw. The fastening to the component can comprise or be an indirect fastening, in which the fastening section is connected to at least one further object, which in turn is connected to the component. Such an object can be a wall element, for example, as described below. Such an object does not necessarily have to be part of the climbing shoe. The fastening to the component can be indirect via one or more intermediate parts, such as steel belts, for example in the area of ​​balconies. For example, a substructure such as e.g.B: A steel framework can be attached to the component, and the fastening section can be attached to the substructure. Depending on the application, the distance between the component and the fastening section can range from several meters to 20 meters or more.

[0021] In one embodiment, the fastening part is designed as a ceiling part. A ceiling part can also be referred to as a ceiling anchoring element. In this case, the climbing shoe can be referred to as a ceiling shoe. Here, the fastening section is designed to be fastened to a manufactured component with an at least substantially horizontal surface, for example a ceiling. The fastening section of the ceiling part can have a support part for resting on the substantially horizontal surface. The fastening section can have a wall fastening region for fastening to a substantially vertical part of the manufactured component, for example a wall. The wall fastening region can have an abutment part for bearing against the vertical part.The wall fastening area can be configured to fasten the fastening part to the vertical part, in particular by means of a wall element described in detail below. The fastening can, in particular, be such that the fastening part is positively secured against rearward movement. A ceiling part is typically shorter in the vertical direction or downwards than a wall part described below, so that it can be fastened to the wall while the ceiling formwork is still present.

[0022] The substantially vertical part of the manufactured component refers to a part that extends primarily upwards. In the case of an inclined surface to be manufactured, the orientation of this part may deviate from the vertical within an angular range of ±30°, for example.

[0023] In one embodiment, the fastening part is designed as a wall part. A wall part can also be referred to as a wall anchoring element. In this case, the climbing shoe can be referred to as a wall shoe. Here, the fastening section is designed to be fastened to a manufactured component with an at least substantially vertical surface, for example a wall. In particular, a wall part does not protrude forward beyond the surface of the manufactured wall. The fastening section of the wall part comprises at least one and preferably two wall fastening regions for fastening to a substantially vertical part of the manufactured component, for example a wall. An upper wall fastening region is designed in particular for fastening the fastening part to the vertical part by means of a wall element described in detail below. In this way, the wall part can be anchored in the manufactured component.A lower wall fastening area is specifically designed to act as a support element for the manufactured component. This allows the wall component to be supported against the manufactured surface.

[0024] A wall element is a component which is fastened to the manufactured component with its essentially vertical surface, in particular with a screw. For this purpose, a hole for a screw is provided in the surface. A wall element is also referred to as an anchor block. A wall element can be essentially plate-shaped. A wall element can comprise a step on each of two opposite sides, in particular on the right and left, which the fastening section can engage behind. The wall element can also comprise a step at the top. The step can be designed to run all the way around the sides and top. A wall element can be designed such that the fastening part can be pushed onto the wall element, in particular from above. In particular, the climbing shoe can be hooked into the wall element.

[0025] To secure the wall element (anchor block), a ceiling component (ceiling anchoring element) can have a slotted hole to compensate for any horizontal deviation in the position of the hole in the finished surface. Since the support element resting on the ceiling determines the angular position of the ceiling component, a straight fit can be ensured in a ceiling component even if the wall element is mounted off-center. In the case of a wall component, a hole centered in the transverse direction is preferably provided to ensure a straight fit of the ceiling component on the surface.

[0026] A locking bar can be provided for positively securing the fastening part to the manufactured component, particularly against upward movement. In particular, the locking bar can be inserted essentially horizontally into the climbing shoe, preferably manually, to prevent upward movement of the climbing shoe relative to a wall component. The locking bar can, in turn, be secured against withdrawal, for example, with a split pin.

[0027] The guide claw engages around at least part of the construction aid. By engaging around we mean that an area of ​​the guide claw is positioned behind the part in such a way that the part and / or the entire construction aid is prevented from moving backwards. Rear basically means the side facing away from the surface of the manufactured component. The part cannot therefore be removed from the manufactured component surface. In other words, the guide claw serves to introduce horizontal forces into the manufactured component. The guide claw guides the part and thus the construction aid during the upward movement, in particular in a substantially vertical or inclined direction. In particular, the part is then located between the guide claw and the fastening section of the climbing shoe. The fastening section is arranged between the manufactured component and the part during use.A guide claw may also be referred to as a side claw. A guide claw preferably comprises a guide surface that contacts a rear side of the part of the construction aid and thus guides it. Each guide claw may have a guide surface that is curved when viewed from the side in order to guide the construction aid in different angular positions.

[0028] A guide claw is connected to the rest of the fastening part, in particular by means of two, in particular vertical, bolts. A first bolt can serve as a pivot axis for pivoting the guide claw. Pivoting can occur between a gripping position for grasping the construction aid and a rest position and back. A second bolt can serve as a locking bolt to secure the position of the guide claw in the gripping position. In this way, fastening to and detaching from the construction aid is possible in a particularly simple manner. The first bolt can be fastened in such a way that it cannot be removed without destruction. In this case, the guide claw is firmly mounted on the fastening part. However, it is not excluded that the guide claw can be detachably connected to the rest of the fastening part, in particular manually.Such a connection or release of the guide claw then has no effect on the connection of the latch device to the fastening part. In other words, the guide claw and latch device can then be connected and / or released independently of each other.

[0029] A construction aid, in particular a climbing rail, can have one and preferably two gripping sections, which can be arranged at least substantially parallel to the surface of the manufactured component. In particular, the guide claw engages around at least one gripping section of the construction aid. A gripping section can be provided by a belt or part of a belt of a steel girder. The construction aid can be pushed upwards and held there.

[0030] A latch device is a device that includes a latch. A latch serves to hold a part of the construction aid, in particular a support element of the construction aid. A latch, in particular, comprises a surface on which a support element can rest in order to be held. The latch can also be referred to as a vertical claw. In one embodiment, the latch device is designed as a latch.

[0031] In particular, the part of the construction aid to be held is a support element of a climbing rail. The latching device is particularly designed to absorb the vertical force of the construction aid and transfer it to the fastening part.

[0032] A connection within the meaning of the invention means one that does not detach spontaneously during intended use. This does not necessarily require a fixed or positive connection in all spatial directions. Inserting one part into another along the direction of gravity, with the inserted part secured against lateral slipping or sliding out, can constitute a connection within the meaning of the invention. A connection is detachable if it can be removed non-destructively, particularly manually.

[0033] In one embodiment, the fastening part comprises two guide claws for gripping the construction aid from two sides. Each guide claw grips a part of the construction aid. The gripping occurs in such a way that any lateral movement is also blocked. In this way, the corresponding part of the construction aid, e.g., the climbing rail, is securely held and guided without the need for an additional component.

[0034] In particular, at least one guide claw, preferably both guide claws, are pivotable.

[0035] In one embodiment, the latch device has a hook-shaped latch for holding a part of the construction aid. In particular, the latch is movable from a holding position to a sliding position and back. A hook-shaped latch is a latch with a hook shape. The hook shape ensures secure hold, in particular of the support element. In particular, the latch is designed to engage behind at least part of the support element when held. Thus, the support element is prevented from accidentally slipping off the latch by a positive fit. The latch is movable, in particular, relative to the rest of the latch device. In particular, the latch device comprises a base plate.

[0036] The holding position allows the construction aid to be held. In the holding position, the latch is moved away from the fastening section and / or toward the climbing rail, so that a support element of the construction aid can be held by the latch, in particular, can rest on the latch. The sliding position allows the construction aid to be moved relative to the climbing shoe. In the sliding position, the latch is moved in particular toward the fastening section, so that support elements of the construction aid can pass the latch.

[0037] In one embodiment, the latch is displaceably mounted. In one embodiment, the latch is pivotable, in particular about a horizontal axis. In particular, the latch is pivotable from the holding position to the displacement position and back. The latch is pivotable, in particular, within a limited angular range. In particular, stop elements are provided that limit the angular range within which the latch is pivotable. In particular, the latch device is configured such that, when properly arranged, the latch is moved toward the holding position due to gravity. This increases safety. The horizontal axis is preferably arranged at the lower end of the latch device.

[0038] In one embodiment, the latch device comprises a spring with which the latch is preloaded toward the holding position. The spring pushes or pulls the latch toward the holding position. The spring is configured such that it exerts a force on the latch in at least one position of the latch. The spring thus contributes, possibly assisted by gravity, to ensuring that the latch is always in the holding position. This increases safety. Since such a latch device is technically complex, a particularly significant advantage is achieved by the detachability of the latch device according to the invention and the associated smaller number of latch parts required.

[0039] A spring, as defined by the invention, is a resilient element that can exert a force due to elastic preload. In particular, the spring is made of metal. The spring can be flat or spiral-shaped, for example. The spring can be configured to exert a compressive and / or tensile force.

[0040] In one embodiment, the latch device comprises a housing and / or the fastening part comprises a cavity. In particular, the housing can be inserted into the cavity. The housing is in particular an open housing, i.e. provided with at least one opening. This allows weight to be saved. In particular, insertion (or hanging) can take place from above. In this way, the connection is supported on the one hand by gravity and on the other hand, when loaded by the construction aid, by the weight of the construction aid. A detachable connection can be created by insertion. The cavity can be formed from or encompassed by several parts.

[0041] In particular, the housing and / or the opening are conically shaped, at least in sections, at least in one viewing direction. This facilitates insertion of the housing into the opening. In particular, a conical shape is present in a viewing direction parallel to the manufactured component surface. In this way, the walls of the housing and / or the opening can be aligned parallel in the viewing direction perpendicular to the component surface. This is preferable for static reasons.

[0042] In particular, the latch is pivotably mounted on the housing. In particular, the cavity is located between the guide claws. This enables a particularly compact design. In another embodiment, the latch device can also be mounted externally on the fastening part. This facilitates handling. In particular, a contact surface is provided on the housing, against which a sliding device rests and engages when the construction aid is pushed up or climbed.

[0043] This design facilitates simplified assembly of the latch device by simply inserting or plugging it in, in particular from above. No separate fastening means, such as a plug-in shaft known from the prior art, is necessary to create a secure and firm connection between the latch device and the fastening part. In one design, the cavity is formed by at least one U-shaped vertical plate and / or by at least one U-shaped horizontal plate. The horizontal plate and / or the vertical plate is U-shaped at least in some areas, so that an opening area is present between two legs of the U-shape. In particular, the legs of the “U” delimit the cavity at least in some areas.

[0044] At least one, and in particular two, vertical plates can form an upwardly open recess. At least one horizontal plate can form a rearwardly open recess. The cavity can comprise the rearwardly and / or upwardly open recesses. A guide claw can be attached, in particular pivotably, to a horizontal plate.

[0045] The fastening part can have a first guide element for guiding the latch device. This allows a guided, in particular vertical, movement of the latch device relative to the fastening part. The first guide element can be an edge or surface of the fastening part, in particular in the region of a cavity. The first guide element can be formed by a leg of a U-shaped vertical plate. In particular, the latch device comprises a first guide part for contacting the first guide element during the relative movement. The first guide part can be an edge or surface of the latch device, in particular located on the outside of a housing of the latch device.

[0046] To close the recess opening to the rear, at least one closure element can be provided in the rear region of the recess. In particular, a stepped closure element is provided on each of the vertical plates. In particular, a projection is provided on each of the lateral outer walls of the housing, which projection is located in front of the corresponding closure element and / or between the legs of the "U" when the latch device is connected to the fastening part. In this way, the latch device can be reliably prevented from being pushed out backwards.

[0047] In particular, the cavity is bounded at the bottom by at least one base element. This can be designed as a horizontal plate, arranged between vertical plates, and / or formed in the form of several support elements only in the edge regions of the cavity. In one embodiment, the climbing shoe is designed such that, in the connected state, a base part of the latch device is supported on the base element of the fastening part.

[0048] In particular, a conical opening area is provided above a U-shaped opening area of ​​at least one vertical plate at the front and / or rear. This facilitates insertion. Vertical plates are connected to one another in particular by external, preferably horizontal webs.

[0049] In one embodiment, the climbing shoe includes a safety device that prevents the connection between the ratchet device and the fastening part from becoming loose. This ensures that the connection cannot be accidentally released, increasing safety.

[0050] In one embodiment, the securing device comprises a blocking element for positively blocking the latching device in the connected state. In particular, the securing device further comprises a spring for biasing the blocking element into a blocking position. In particular, the blocking element is configured to prevent the latching device from being pulled out by positive locking. The blocking element can be moved from a blocking position to a release position and back, e.g., by sliding.

[0051] Typically, the climbing shoe is designed so that when the ratchet device is inserted, the locking element is temporarily moved from the locking position to the release position and then returns to the locking position. For this purpose, a ramp-shaped contact surface, for example, can be provided that moves the locking element upon insertion. This creates an automatic locking mechanism, which increases safety and eliminates operating errors.

[0052] In particular, a free end of the blocking element is located in a recess when the blocking element is in the blocking position. In other words, the blocking element locks into the recess for blocking. In this way, a positive connection can be established in a simple and secure manner.

[0053] In one embodiment, the blocking element and / or the spring for preloading the blocking element is arranged on the latch device. Accordingly, the recess is arranged in particular on the fastening part. This makes the fastening part particularly simple and cost-effective to manufacture. The technically more complex spring mechanism is part of the latch device, which is required in significantly smaller quantities. This reduces the overall cost.

[0054] In one embodiment, the latch device comprises a handle for manual holding. In one embodiment, a free space for engaging a hand is provided adjacent to the handle. In one embodiment, the securing device is arranged adjacent to the free space, particularly when the latch device is connected to the fastening part.

[0055] In particular, the latch device comprises a handle for manually holding the latch device. The handle is particularly attached to the upper end of the latch device and / or designed as a rod aligned parallel to the component surface. The handle enables easy manual removal of the latch device. In particular, the blocking element of the securing device is arranged adjacent to the free space. This way, it is always clearly visible whether the blocking element is in the blocking position or the release position. An accidentally unsecured state can thus be easily and safely detected and remedied.

[0056] In one embodiment, the latch device can be connected to the fastening part in different positions, in particular at different heights. The different positions refer to relative positions of the latch device in relation to the fastening part. In particular, the climbing shoe comprises an adjustment means for adjusting a relative position of the latch device in relation to the fastening part. In particular, the adjustment means is provided for continuously adjustable and / or for adjusting a height position of the latch device. The adjustment means can have a screw that is rotatable in the latch device or the fastening part or a component connected to the latch device or the fastening part and presses against the respective other part of the climbing shoe. Depending on the screw-in position of the screw, different positions of the latch device can thus be realized.In this way, deviations, especially vertical deviations, in the position of the hole in the manufactured surface can be compensated.

[0057] In one embodiment, the climbing shoe has a covering means which at least partially covers a connection area between the fastening part and the latch device. The covering means covers the connection area upwards. The covering means serves to protect the connection area, in particular from liquid concrete or falling objects. The connection area comprises the points and / or surfaces at which the fastening part and the latch device contact each other. The covering means can be plate-shaped. The covering means can be made of a flexible material, for example rubber or plastic. The covering means can be pivotable and / or fastened in order to expose the fastening area for fastening or releasing the latch device. In particular, the covering means is fastened to the fastening part, for example by screwing.

[0058] A further aspect of the invention is a latch device for a climbing shoe, in particular according to the invention. The latch device is designed to hold a construction aid. The latch device is designed for detachable connection to a fastening part of a climbing shoe.

[0059] A further aspect of the invention is a fastening part for a climbing shoe, in particular according to the invention. The fastening part comprises a fastening section for fastening to a manufactured concrete component and at least one guide claw for gripping a construction aid. The fastening part is designed for releasable connection to a latch device of a climbing shoe.

[0060] All features, advantages and effects of the climbing shoe and its parts described at the outset, in particular the latch device and the fastening part, can apply accordingly to the aspects of the invention mentioned here and vice versa.

[0061] A further aspect of the invention is a method for producing at least a section of a component from concrete. A latch device, in particular of a climbing shoe according to the invention, is released and removed from the fastening part of the climbing shoe, while at the same time a construction aid is held by the guide claw. For example, the latch device can be connected to another, in particular higher-lying, fastening part of a climbing shoe. All features, advantages, and effects of the climbing shoe and its parts described above can apply accordingly to this aspect of the invention and vice versa. A further aspect is a method for producing at least a section of a component from concrete, wherein a fastening part, in particular according to the preceding claim, is used to introduce horizontal forces of the construction aid into the finished section of the component.Vertical and horizontal forces of the construction aid are forces acting vertically and horizontally on the climbing shoe, respectively, originating from the construction aid. In particular, they result from the weight of the construction aid, as well as from objects and people located on or near it, as well as loads that occur during use, such as wind loads. In other words, a climbing shoe with a fastening part, which includes a fastening section for fastening to a manufactured section of the concrete component and at least one guide claw for gripping the construction aid, is used to transfer horizontal forces of the construction aid into the finished section of the component.

[0062] In particular, the fastening part or the climbing shoe does not comprise a latching device. The fastening part or the climbing shoe is, in particular, not designed to introduce vertical forces into the manufactured component. In particular, a climbing shoe according to the invention with a latching device is additionally used to introduce vertical forces into the component at a different position of the manufactured component. All features, advantages, and effects of the climbing shoe and its parts described above can apply accordingly to this aspect of the invention, and vice versa.

[0063] A further aspect of the invention is a system comprising two or more fastening parts, in particular according to the invention, and a number of latching devices, in particular according to the invention, wherein the number of latching devices is fewer than the number of fastening parts. For example, the system comprises two fastening parts and one latching device. The system serves to move a construction aid, for example, a climbing rail.

[0064] Below, exemplary embodiments of the invention are explained in more detail with reference to the figures. Features of the exemplary embodiments can be combined individually or in multiples with the claimed subject matter, unless otherwise stated. The claimed scope of protection is not limited to the exemplary embodiments.

[0073] Figure 7: a side view of another embodiment of a climbing shoe.

[0074] Figure 1 shows a fastening part 20 according to the invention for a climbing shoe. In particular, the parts described here are made of steel, unless otherwise indicated. The fastening part 20 comprises a fastening section 19 for fastening to a manufactured section of a component 11 made of concrete. The fastening part 20 shown is designed as a wall part for arrangement on a substantially vertically oriented wall of the component 11. The fastening section 19 comprises two wall fastening regions 21. The upper wall fastening region 21 is fastened to a wall element screwed separately to the wall, as described below with reference to Figure 5. The lower wall fastening region 21 lies flat against the wall or is supported on it.

[0075] The fastening part 20 further comprises two guide claws 17 for gripping a construction aid 14 from two opposite sides. The construction aid 14 is designed as a climbing rail 15 and comprises two supports, for example, 11(UNP) or UPE profiles (see Fig. 3), arranged opposite one another and / or connected to one another by means of horizontal support elements 16 and / or vertically aligned. The support elements 16 can be, for example, chord bolts. Each guide claw 17 has a guide surface 18 with which it grips a flange of the profile (see Fig. 2). In this way, the profile is held firmly in all directions perpendicular to its longitudinal direction and is movably guided along the longitudinal direction.

[0076] The fastening part 20 contains an upwardly open cavity 22 into which a latch device according to the invention can be inserted (see Figs. 3 and 4). The fastening part 20 comprises two parallel vertical plates 23, each U-shaped. The cavity 22 is located between the legs 25 of the "U" when viewed transversely. A latch device with a housing and projections arranged laterally on the housing can thus be firmly held in the cavity 22, since the projections lie between the respective legs 25 of each vertical plate 23 and are thus held in a form-fitting manner from three sides.

[0077] Figure 2 shows the fastening part 20 fastened to the component 11, in particular from Figure 1, in a plan view. The structure of the climbing rail 15 and the way it is gripped by the guide claws 17 is clearly visible here. Each guide claw is fastened with two bolts 26, 27. A first bolt 26 is designed as a vertically aligned pivot axis for pivoting the respective guide claw 17. The first bolt can firmly connect the respective guide claw 17 to the rest of the fastening part 20. A second bolt 27 is designed as a manually detachable plug pin, which can be secured in particular by means of a split pin. The second bolt 27 serves to fix the respective guide claw 17 in the gripping position shown, in which the climbing rail 15 is held or guided.After removing the second bolt 27, the respective guide claw 17 can be pivoted outwards away from the climbing rail 15 and the climbing rail 15 can be released in this way.

[0078] A horizontal plate 24 is U-shaped and surrounds the upwardly open cavity 22. In the plan view shown, the cavity is located between the legs 25 of the "U." At the bottom of each leg 25, there are stepped projections on both sides, which interact with suitable steps on the housing of the latch device and thus prevent it from being pulled out backward.

[0079] Furthermore, Figure 2 shows the wall element 12, which is fastened with a screw 13 in a cone of the component 11 (see also Figure 5). The wall element has a step arranged around it or at least on both sides, behind which a stepped area of ​​the fastening section 19 or wall fastening area 21 lies and is thus secured against backward movement.

[0080] Figure 3 shows a step in the assembly of a climbing shoe according to the invention. The climbing rail 15 is still held or guided by the guide claws 17. A latch device 30 is located above the fastening part 20 in a slightly rotated position. The latch device 30 assumes this position temporarily, particularly for reasons of space, when it is being installed or removed while the climbing rail 15 is being held.

[0081] The latch device 30 comprises a hook-shaped latch 32 for holding the construction aid, namely for supporting a support element 16. The latch device further comprises a housing 38 for insertion into the cavity 22 of the fastening part 20. The latch 32 is pivotally mounted, namely from the illustrated holding position into a sliding position and back. This is described in detail in Figure 5. A spring 36, in particular designed as a leaf spring, biases the latch 32 toward the holding position.

[0082] The latch device 30 comprises on its upper side a handle 45 designed as a transverse rod, which is arranged next to a free space 46 for manual engagement. A blocking element 42, preloaded by a spring 36, is clearly visible next to the free space 46. The blocking element 42 serves to positively block the withdrawal of the latch device 30 from the cavity 22 and is described in detail with reference to Figure 6.

[0083] In Figure 4, the latch device 30 is almost completely inserted into the cavity 22. The position of the guide claws 17 remains unchanged. The upper surfaces of the curved guide surfaces are clearly visible in this figure.

[0084] In Figure 5, the latch device 30 is connected to the fastening part 20. The guide claws 17 are hidden here for reasons of clarity, but are nevertheless positioned unchanged.

[0085] It is visible that the latch 23 is pivotally mounted about the axis 35. An arcuate slot 31 serves as a guide for bolts 37 and thus as a front and rear stop to limit the pivoting movement of the latch 23. In the holding position 33 shown, a support element 16 of the construction aid 14, here the climbing rail 15, is located in the hook-shaped recess of the latch 23 and is held there. The vertical force of the construction aid is thus introduced into the component 11 via the climbing shoe 10. During climbing, the climbing rail is moved upwards, guided by the guide claws. A following support element 16 contacts the underside of the latch 23 and pivots it into the sliding position. Due to the force of the spring 36 and / or gravity, it then pivots back into the holding position 33. The following support element 16 can then be held.

[0086] Also shown is the attachment of the wall element 12 to the component 11. A cone 50 is provided in the component 11, into which the screw 13 is screwed. The screw 13 holds the wall element 12, on which the upper wall attachment portion 21 sits. A plate-shaped rubber cover 52, attached on one side, partially covers the connection area between the attachment portion 20 and the latch device 30.

[0087] Figure 6 shows detail “A” from Figure 5 in an enlarged view. The previously described elements, handle 45, free space 46, and blocking element 42, are shown. The blocking element 42 is designed as a latch and is part of the securing device 40 provided on the latch device 30. In the blocking position shown, the blocking element 42 blocks the latch device 30 with respect to the fastening part 20 in a form-fitting manner. The tip of the blocking element 42 is inserted into a recess 47 in the fastening part 20. Due to the essentially horizontal orientation of the blocking element 42, an upward movement of the latch device 30 is effectively prevented. A spring 43 preloads the blocking element in the direction of the blocking position. The blocking element 42 is guided laterally in slots in the housing 38.A plate-shaped actuating element 44 is arranged vertically on the blocking element 42 and projects upwards, with which it can be pushed back manually - in particular when gripping the latch device 30 by means of the handle 45 - in order to move the blocking element 42 into the release position against the force of the spring 43 and to release the latch device.

[0088] Figure 7 shows a side view of an alternative embodiment in which the fastening part 20 is designed as a ceiling part for arrangement on a ceiling of the component 11 with a substantially horizontal surface. The fastening section 19 comprises a wall fastening region 21 which, analogous to the embodiments described above, is fastened to a wall element 12 separately screwed to the wall. The fastening section 19 further comprises a ceiling fastening region 29 which rests flat on the horizontal surface and is configured to introduce vertical forces into the component 11. In addition, the climbing shoe comprises an adjustment means 53 for adjusting a relative position of the latch device with respect to the fastening part 20. This enables the latch device to be connected to the fastening part at different height positions.The adjusting means 53 comprises an adjusting screw which bears against the fastening part 20 and presses against the pawl device 30 in order to change the relative position between these parts.
