Climbing shoe, latch device, attachment member and method

Description

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

A construction aid is an aid that is used for the construction of buildings. Examples of structures are buildings, bridges or walls. To erect such structures, cranes, scaffolding and formwork are used. With such construction aids, there may be a risk that people and objects such as tools, bolts, screws, rubble, etc. could fall from a great height. In order to avoid associated risks, construction aids can have protective devices that protect against falling. Protective devices may include railings, grilles, nets, walls, etc.

A formwork is a mold. Fresh concrete can be poured into the mold. After the concrete has hardened, the formwork can usually be removed. For example, components of buildings or bridges can be manufactured. Examples of components are walls, ceilings, shafts and supports.

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 at least partially curved. Supporting elements may be present on the back of the panel, such as a frame, side members and/or cross members. 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 and in this way shapes the surface of the component.

A frame of a formwork panel generally does not protrude from the front of the panel. A formwork panel can include 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 so that an anchor no longer comes out of the anchor holes can be pulled out. 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, preferably also tensile forces. Two opposing formwork panels can be connected to each other using one or more anchors.

An example of a construction aid is a climbing frame. A climbing frame can be attached to an already completed section of a structure. A part of the climbing frame, for example a climbing rail, can be moved upwards and then held, 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 in order to prepare a following 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 takes place with a suitable pushing device, for example hydraulically driven. This way no crane is needed for this. You can also climb down, for example to demolish at least part of a building or component. Here, a downward push and/or a downward movement due to gravity can take place.

A stage can be attached to the climbing frame and can be moved to a desired height. The stage can be walked on. One or more formwork panels can be present on or on the stage or independently of the stage in order to form a formwork. A protective device can be attached to the platform to protect against falling. A climbing frame with additional components attached to it such as a platform, formwork panel and/or protective device is called a climbing system.

A climbing rail is an elongated, essentially vertically oriented element that is pushed upwards relative to the climbing shoe. When climbing downwards, the climbing rail moves downwards in relation 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 essentially aligned horizontally. The pawl device can be set up to hold at least one support element. To hold the construction aid, e.g. B. the climbing frame, a climbing shoe is used on the manufactured component. A climbing shoe is attached to a manufactured concrete component, 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 enables the construction aid to be moved upwards and/or that enables the construction aid to be held in different positions of the construction aid. After moving, a climbing shoe holds the construction aid in the pushed-up position. Typically, each climbing rail is held with at least two climbing shoes, which are arranged in different height positions, preferably one above the other. If a climbing shoe is no longer needed, for example because the lowest climbing shoe is arranged too low to hold the construction aid that has been moved upwards, it is removed from the manufactured component and, in particular, reattached at a higher position. This means that the climbing shoe can be used for a subsequent concreting section.

The above-mentioned features, effects and definitions can be combined individually or in a plurality with the claimed and described subjects.

Since a climbing shoe includes the above-mentioned mechanics, it is usually 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. The document EP 1 899 548 B1 discloses such a climbing shoe with a wall shoe part for attaching to a vertical wall and a sliding shoe part with claws for gripping a climbing rail and a pawl for carrying the climbing rail. The wall shoe part and the sliding shoe part are detachably connected to one another by means of a plug-in shaft. This leads to complex coupling and release and not very flexible use of the climbing shoe.

It is the object of the invention to provide a further developed climbing shoe, an associated pawl device, an associated fastening part and a method with which, in particular, more flexible and safe use is possible. The task is solved by the climbing shoe according to claim 1 and the latch device, the fastening part and the method according to the independent claims. Advantageous refinements are specified in the subclaims.

A climbing shoe for a construction aid is used to solve the task. The climbing shoe comprises a fastening part with a fastening section for fastening to a manufactured component made of concrete and with at least one guide claw for gripping the construction aid. The climbing shoe further comprises a latch device that can be detachably connected to the fastening part for holding the construction aid.

The latch device can be detachably connected to the fastening part, in particular manually. For example, the pawl device can be inserted into a cavity of the fastening part. There is at least one guide claw. The fastening part with the fastening section and the guide claw can thus remain attached to the manufactured component while the latch device is loosened and removed. Loosening the pawl device has no influence on the attachment of the guide claw. In particular, the pawl device can be released and/or removed while the construction aid is gripped by the guide claw.

An advantage of the invention is that the latch device only needs to be present on the climbing shoes where it is actually needed. The latch 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 hardened, vertical forces and horizontal forces are usually introduced into the component at separate positions, namely with separate climbing shoes. Typically, vertical forces are applied to a lower climbing shoe and/or horizontal forces are applied to an upper climbing shoe. In this case, the latch device is only necessary on the lower climbing shoes. Significantly fewer latch devices are required, so that the technical effort on the construction site and the manufacturing costs are reduced.

In connection with this, the invention also eliminates a source of errors on the construction site. Because there is currently a latch device on every climbing shoe, it can happen that a climbing shoe was incorrectly used to introduce vertical and horizontal forces. This can cause the climbing shoe to be overloaded and/or the load-bearing capacity of the not yet fully hardened concrete to be exceeded. According to the invention, the vertical force can only be introduced on climbing shoes that include a latch device. So only as many latch devices are provided as there are climbing rails. This effectively prevents the vertical force from being applied to a climbing shoe that is not intended for this purpose. The load transfer is easy to see.

The divisibility also enables the fastening part and latch device to be transported separately on the construction site, so that the weight to be carried is minimized. In particular, the fastening part and/or the latch device has a weight that does not exceed 25 kg. This makes transport on the construction site easier and ensures improved occupational safety.

The fastening part is used to fasten 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 set up for fastening to a component made of a different material. The climbing shoe can, for example, B. can be used for the production 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.

The fastening section serves to fasten the climbing shoe to the manufactured component. The attachment to the component can include or be a direct attachment, in which the attachment section is connected directly to the component, e.g. B. using a screw. The attachment to the component can include or be an indirect attachment, in which the attachment section is connected to at least one further object, which in turn is connected to the component. Such an object can be, for example, a wall element, as described below. Such an item does not necessarily have to be part of the climbing shoe. The attachment to the component can be done indirectly via one or more intermediate parts such as. B: Steel belts are used, for example in the Baikonen area. For example, a substructure such as B: a steel framework is attached to the component and the Fastening section can be attached to the substructure. Depending on the application, there can be a distance of several meters to 20 m or more between the component and the fastening section.

In one embodiment, the fastening part is designed as a ceiling part. A ceiling part can also be called 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 may have a support part for resting on the substantially horizontal surface. The fastening section may have a wall fastening area for fastening to a substantially vertical part of the manufactured component, for example a wall. The wall mounting area may have a contact part for abutting the vertical part. The wall fastening area can be set up to fasten the fastening part to the vertical part, in particular by means of a wall element described in detail below. The attachment can in particular be such that the attachment part is secured in a form-fitting manner against rearward movement. A ceiling part is typically shorter in the vertical direction or downwards than a wall part described below in order to be able to be attached to the wall while the ceiling formwork is still in place.

The substantially vertical part of the manufactured component means a part that extends mainly upwards. In the case of an inclined surface to be produced, the orientation of this part can deviate from the vertical within an angular range of ±30°, for example.

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 wall produced. The fastening section of the wall part comprises at least one and preferably two wall fastening areas for fastening to a substantially vertical part of the manufactured component, for example a wall. An upper wall fastening area is particularly for fastening the Fastening part set up on 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 set up in particular as a system part for resting on the manufactured component. In this way, the wall part can be supported on the surface produced.

A wall element is a component that is attached to the manufactured component with the essentially vertical surface, in particular with a screw. For this purpose, a hole is provided in the surface for a screw. A wall element is also called an anchor block. A wall element can be essentially plate-shaped. A wall element can each have a step on two opposite sides, in particular on the right and left, which can be reached behind by the fastening section. The wall element can also include a step at the top. The step can be designed to run around the sides and top. A wall element can be set up in such a way that the fastening part can be pushed onto the wall element, in particular from above. In particular, the climbing shoe can be hung into the wall element.

To attach the wall element (anchor block), a ceiling part (ceiling anchoring element) can have an elongated hole in order to compensate for a horizontal deviation in the position of the hole in the manufactured surface. Since the support part resting on the ceiling determines the angular position of the ceiling part, a straight fit can be guaranteed for a ceiling part even if the wall element is attached off-center. In the case of a wall part, a central hole in the transverse direction is preferably provided in order to ensure a straight fit of the ceiling part on the surface.

A locking bar can be provided for positively securing the fastening part on the manufactured component, in particular against upward movement. In particular, the locking bar can be inserted essentially horizontally into the climbing shoe, preferably manually, in order to prevent the climbing shoe from moving upwards relative to a wall part. The locking bar can in turn be secured against being pulled out, for example with a split pin.

The guide claw encompasses at least part of the construction aid. By gripping it is meant 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 is hindered. Back 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 can also be called a side claw. A guide claw preferably comprises a guide surface which contacts and in this way guides a rear side of the part of the construction aid. Each guide claw can have a guide surface that is curved when viewed from the side in order to guide the construction aid in different angular positions.

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 take place between a gripping position for gripping the construction aid and a rest position and back. A second bolt can serve as a securing bolt to secure the position of the guide claw in the gripping position. In this way, attaching to the construction aid 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 being destroyed. The guide claw is then 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 loosening or connecting of the guide claw then has no influence on a connection of the pawl device to the fastening part. In other words, the guide claw and the pawl device can then be connectable and/or detachable independently of one another.

A construction aid, in particular a climbing rail, can have one and preferably two handle sections, which can in particular be arranged at least substantially parallel to the surface of the manufactured component. In particular, the guide claw encompasses at least one handle section of the construction aid. A grip section may be provided by a strap or part of a strap of a steel beam be provided. The construction aid can be pushed up and held there.

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 in this way. The pawl can also be referred to as a vertical claw. In one embodiment, the pawl device is designed as a pawl.

In particular, the part of the construction aid to be held is a support element of a climbing rail. The pawl device is designed in particular to absorb the vertical force of the construction aid and to transmit it to the fastening part.

A connection in the sense of the invention means a connection that does not come apart on its own when used as intended. There does not necessarily have to be a solid or positive connection in all spatial directions. Inserting one part into another along the direction of gravity, in which the inserted part is secured against lateral slipping and pushing out, can represent a connection in the sense of the invention. A connection is detachable if it can be detached non-destructively, especially manually.

In one embodiment, the fastening part comprises two guide claws in order to grip the construction aid from two sides. Each guide claw grips a part of the construction aid. The grip is carried out in such a way that any lateral movement is blocked. In this way, the corresponding part of the construction aid, e.g. B. the climbing rail, safely held and guided without the need for an additional component.

In particular, at least one guide claw, preferably both guide claws, is pivotable.

In one embodiment, the latch device has a hook-shaped latch for holding part of the construction aid. In particular, the pawl can be moved from a holding position into a displacement position and back. A hook-shaped latch is a latch with a hook shape. The hook shape ensures a secure hold, especially of the support element. In particular, the latch is designed to to reach behind at least part of the support element when holding. This means that the support element is prevented from slipping off the latch in an unplanned manner due to positive locking. The pawl is in particular movable relative to the rest of the pawl device. In particular, the latch device comprises a base plate.

The holding position allows the construction aid to be held. In the holding position, the pawl is moved in particular away from the fastening section and/or in the direction of the climbing rail, so that a support element of the construction aid can be held by the pawl, in particular can rest on the pawl. The displacement position enables the construction aid to be displaced relative to the climbing shoe. In the displacement position, the pawl is moved in particular in the direction of the fastening section, so that support elements of the construction aid can pass through the pawl.

In one embodiment, the pawl is mounted in a displaceable manner. In one embodiment, the pawl is pivotable, in particular about a horizontal axis. In particular, the pawl can be pivoted from the holding position into the displacement position and back. The pawl can be pivoted in particular within a limited angular range. In particular, there are stop elements which limit the angular range in which the pawl can be pivoted. In particular, the pawl device is set up so that the pawl is moved in the direction of the holding position due to gravity when arranged as intended. This increases security. The horizontal axis is preferably arranged at the lower end of the latch device.

In one embodiment, the pawl device comprises a spring with which the pawl is biased towards the holding position. The spring pushes or pulls the latch toward the holding position. The spring is set up to exert a force on the pawl in at least one position of the pawl. The spring therefore contributes, possibly supported by gravity, to ensuring that the pawl is basically in the holding position. This increases security. On the other hand, since such a pawl device is technically complex, a particularly great advantage is achieved by the detachability of the pawl device according to the invention and the associated smaller number of pawl parts required.

A spring in the sense of the invention is a resilient element which can exert a force due to elastic pretension. In particular, the spring is out Made of metal. The spring can be flat or spiral-shaped, for example. The spring can be set up to exert a compressive force and/or tensile force.

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 way, weight can 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, in the state loaded by the construction aid, by the weight of the construction aid. By inserting it, a detachable connection can be created. The cavity can be formed from several parts or encompassed by several parts.

In particular, the housing and/or the opening is conically shaped, at least in sections, at least in one viewing direction. This makes it easier to insert the case 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 to the component surface in the viewing direction perpendicular to the component surface. This is preferable for static reasons.

In particular, the pawl is pivotably arranged on the housing. In particular, the cavity is arranged between the guide claws. This enables a particularly compact design. In a further embodiment, the latch device can also be mounted on the outside of the fastening part. This makes handling easier. 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.

This configuration facilitates simplified assembly of the latch device by simply inserting or plugging it in, especially from above. No separate fastening means, such as a plug-in shaft known from the prior art, is necessary to establish a secure and firm connection of the pawl device to the fastening part. In one embodiment, 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 at least partially U-shaped, so that an opening area is present between two legs of the U-shape. In particular, the legs of the “U” limit the cavity, at least in some areas.

At least one and in particular two vertical plates can form a recess that is open at the top. At least one horizontal plate can form a recess that opens to the rear. The cavity can include the recesses that are open towards the rear and/or upwards. A guide claw can be attached to a horizontal plate, in particular pivotable.

The fastening part can have a first guide element for guiding the pawl device. In this way, a guided, in particular vertical, movement of the pawl device can take place in relation to the fastening part. The first guide element can be an edge or surface of the fastening part, in particular in the area of a cavity. The first guide element can be formed by a leg of a U-shaped vertical plate. In particular, the pawl 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 pawl device located in particular on the outside of a housing of the pawl device.

To close the recess that is open to the rear, at least one closure element can be present in the rear area of the recess. In particular, a step-shaped closure element is present on each of the vertical plates. In particular, there is a projection on each of the lateral outer walls of the housing, which lies 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.

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

In particular, a conical opening area is present above a U-shaped opening area of at least one vertical plate at the front and/or rear. In this way, insertion is made easier. Vertical plates are connected to one another in particular by external, preferably horizontal, webs.

In one embodiment, the climbing shoe comprises a safety device which blocks a loosening of an established connection of the latch device with the fastening part. In this way it can be ensured that the connection is not accidentally disconnected. This increases security.

In one embodiment, the safety device comprises a blocking element for positively blocking the latch device in the connected state. In particular, the securing device further has a spring for biasing the blocking element into a blocking position. In particular, the blocking element is set up in such a way that it prevents the pawl 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. B. by moving.

Typically, the climbing shoe is designed in such a way that when the pawl device is inserted, the blocking element is moved twice from the blocking position to the release position and then returns to the blocking position. For this purpose, for example, a particularly ramp-shaped contact surface can be present, which displaces the blocking element when it is inserted. An automatic backup is created, which increases safety and eliminates operating errors.

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 safe manner.

In one embodiment, the blocking element and/or the spring for biasing the blocking element is arranged on the pawl device. The recess is accordingly arranged in particular on the fastening part. In this way, the fastening part can be produced particularly easily and inexpensively. The technical More complex spring mechanism is part of the latch device, which is required in significantly smaller numbers. This reduces the overall effort.

In one embodiment, the latch device includes a handle for manual holding. In one embodiment, there is free space adjacent to the handle for a hand to intervene. In one embodiment, the safety device is arranged adjacent to the free space, in particular when the pawl device is connected to the fastening part.

In particular, the latch device comprises a handle for manually holding the latch device. The handle is attached in particular to the upper end of the latch device and/or is designed as a rod aligned parallel to the component surface. The handle allows for easy manual removal of the latch device. In particular, the blocking element of the safety device is arranged adjacent to the free space. In this way, it is always clearly visible whether the blocking element is in the blocking position or the release position. In this way, an accidentally unsecured state can be easily and safely identified and remedied.

In one embodiment, the latch device can be connected to the fastening part in different positions, in particular in different height positions. The different positions mean relative positions of the latch device in relation to the fastening part. In particular, the climbing shoe includes an adjustment means for adjusting a relative position of the pawl device in relation to the fastening part. In particular, the adjustment means is provided for continuous adjustment and/or for adjusting a height position of the pawl device. The adjusting means may comprise a screw which 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 other part of the climbing shoe. Depending on the screw-in position of the screw, different positions of the latch device can be realized. In this way, deviations, in particular vertical deviations, in the position of the hole in the surface produced can be compensated for.

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 agent then covers the connection area from the top. The covering means serves to protect the connection area, in particular from liquid concrete or falling objects. The connection area includes the points and/or areas in 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 cover means can be designed and/or attached to be pivotable in order to expose the attachment area for attaching or detaching the latch device. In particular, the covering means is attached to the fastening part, for example screwed.

Another aspect of the invention is a latch device for a climbing shoe in particular according to the invention. The latch device is set up to hold a construction aid. The latch device is set up for a detachable connection to a fastening part of a climbing shoe.

Another 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 component made of concrete and at least one guide claw for gripping a construction aid. The fastening part is designed for a detachable connection to a latch device of a climbing shoe.

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

A further aspect of the invention is a method for producing at least a section of a component made of concrete. A pawl device, in particular of a climbing shoe according to the invention, is detached from the fastening part of the climbing shoe and removed, while at the same time a construction aid is held with 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 described above and its parts 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 made of concrete, wherein a fastening part, in particular according to the previous claim, is used to introduce horizontal forces of the construction aid into the finished section of the component. Vertical forces and horizontal forces of the construction aid are vertically or horizontally acting forces on the climbing shoe that come from the construction aid. In particular, they result from the weight of the construction aid as well as objects and people located on it and on it, as well as loads that occur during use, such as. B. Wind loads. In other words, a climbing shoe with a fastening part, which comprises a fastening section for fastening to a manufactured section of the component made of concrete and at least one guide claw for gripping the construction aid, is used to introduce horizontal forces of the construction aid into the finished section of the component.

The fastening part or the climbing shoe in particular does not include a latch 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 pawl device is additionally used to introduce vertical forces into the component at a different position of the component produced. All features, advantages and effects of the climbing shoe described above and its parts can apply accordingly to this aspect of the invention and vice versa.

A further aspect of the invention is a system of two or more fastening parts in particular according to the invention and a number of latch devices in particular in accordance with the invention, the number of latch devices being less than the number of fastening parts. For example, the system includes two fasteners and a latch device. The system is used to move a construction aid, such as a climbing rail.

Exemplary embodiments of the invention are explained in more detail below using figures. Features of the exemplary embodiments can be combined individually or in a plurality with the claimed subjects, unless otherwise stated.

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 marked. The fastening part 20 includes 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 areas 21. The upper wall fastening area 21 is fastened to a wall element screwed separately to the wall, as described below with reference to FIG. 5. The lower wall fastening area 21 lies flat against the wall or is supported on it.

The fastening part 20 further comprises two guide claws 17 in order to grip around a construction aid 14 from two opposite sides. The construction aid 14 is designed as a climbing rail 15 and comprises two supports arranged opposite one another and/or connected to one another by means of horizontal support elements 16 and/or vertically aligned, for example II(UNP) or UPE profiles (see FIG. 3). The support elements 16 can z. B. be belt bolts. Each guide claw 17 has a guide surface 18 with which it encompasses 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 guided movably along the longitudinal direction.

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 of which is shaped like a U. The cavity 22 is located in the transverse direction between the legs 25 of the “U”. A jack device with a housing and on the side In this way, the projections arranged in the housing can be held firmly in the cavity 22, since the projections come to rest between the respective legs 25 of each vertical plate 23 and are thus held in a form-fitting manner from three sides.

Figure 2 shows the fastening part 20 attached to the component 11, in particular from Figure 1, in a top view. The structure of the climbing rail 15 and the gripping of it by the guide claws 17 are 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 releasable locking 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 release the climbing rail 15 in this way.

A horizontal plate 24 is U-shaped and surrounds the cavity 22, which is open at the top. The cavity is located between the legs 25 of the “U” in the top view shown. At the bottom of the ends of the respective legs 25 there are step-shaped projections on both sides, which interact with suitable steps on the housing of the pawl device and thus prevent it from being pulled out in the rearward direction.

Furthermore, the wall element 12 is visible in Figure 2, which is fastened with a screw 13 in a cone of the component 11 (see also Figure 5). The wall element has a circumferential step or at least a step arranged on both sides, behind which a step-shaped area of the fastening section 19 or wall fastening area 21 lies and is secured in this way against backward movement.

Figure 3 shows a step in assembling 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 twisted position. This position takes the Latch device 30 in particular in the meantime for reasons of space when it is installed or removed while the climbing rail 15 is held.

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

The latch device 30 includes on its top a handle 45 designed as a transverse rod, which is arranged next to a free space 46 for hand gripping. A blocking element 42 preloaded with a spring 36 is arranged in a clearly visible manner next to the free space 46. The blocking element 42 serves to positively block the withdrawal of the pawl device 30 from the cavity 22 and is described in detail with reference to FIG. 6.

In Figure 4, the pawl device 30 is almost completely pushed into the cavity 22. The position of the guide claws 17 is unchanged. The top sides of the arcuate guide surfaces can be clearly seen in this figure.

In Figure 5, the pawl device 30 is connected to the fastening part 20. The guide claws 17 are hidden here for reasons of clarity, but in particular are still positioned unchanged.

It can be seen that the pawl 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 pawl 23. In the holding position 33 shown, there is a support element 16 of the construction aid 14, here the climbing rail 15, in the hook-shaped recess of the pawl 23 and is kept there. The vertical force of the construction aid is thus introduced into the component 11 via the climbing shoe 10. When climbing, the climbing rail is moved upwards, guided by the guide claws. A following support element 16 contacts the underside of the pawl 23 and pivots it into the displacement position. Pivoting then occurs due to the force of the spring 36 and/or gravity back to the holding position 33. The following support element 16 can then be held.

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 fastening area 21 sits. A one-sided, plate-shaped covering means 52 made of rubber partially covers the connection area between the fastening part 20 and the latch device 30.

Figure 6 shows the detail “A” from Figure 5 in an enlarged view. The already 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 safety device 40, which is provided on the pawl device 30. In the blocking position shown, the blocking element 42 blocks the pawl device 30 in relation to the fastening part 20 in a positive manner. The tip of the blocking element 42 is inserted into a recess 47 of the fastening part 20. Due to the essentially horizontal orientation of the blocking element 42, an upward movement of the pawl device 30 is effectively prevented in this way. A spring 43 biases 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, with which it can be pushed back manually - in particular when gripping the pawl 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 to move and release the latch device.

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 includes a wall fastening area 21, which is fastened to a wall element 12 screwed separately to the wall, analogous to the embodiments described above. The fastening section 19 further comprises a ceiling fastening area 29, which rests flat on the horizontal surface and is set up to introduce vertical forces into the component 11. In addition, the climbing shoe includes an adjustment means 53 for adjusting a relative position of the latch device in relation to the fastening part 20. This makes it possible for the Latch device can be connected to the fastening part in different height positions. The adjusting means 53 includes an adjusting screw which bears on the fastening part 20 and presses against the ratchet device 30 to change the relative position between these parts.
