Definitions

• the invention relates to a guide shoe and a climbing system in the field of civil engineering.
• the scaffolding unit does not necessarily have formwork, but for example a safety net projecting outwards from the building to be constructed and / or platforms for access to the building to be created Building including ceilings to be built.
• the latter elements are attached to the scaffold unit.
• Other profiles are attachable to individual parts of the structure, and a reversible drive is provided to raise either the scaffolding unit or the profiles intended for attachment to the structure.
• the invention has for its object to provide a guide shoe and a climbing system in the field of construction, which are improved in terms of an efficient structure.
• the ability to disengage a guide from the scaffold assembly of a climbing system is conveniently realized by providing the guide shoe, hereinafter also referred to as a guide, at least one slidable in the horizontal direction and one horizontal axis pivotable guide jaw, which surrounds a profile, such as a T, I or U-profile, a part or section of a profile.
• a profile such as a T, I or U-profile, a part or section of a profile.
• at least one profile provided on the scaffolding unit may be a T or double T-profile, the horizontal leg of which, viewed on the letter "T", extends parallel to the outside of the structure and directed towards it.
• the guide jaw can engage behind this leg in the region of the vertical leg of the "T" and be retracted by a horizontal displacement out of engagement and by pivoting about a substantially horizontal axis.
• Another advantage of a pivotable attachment of at least one guide jaw on the guide is that punctual loads can be avoided in the event that the guide is rotatably attached to a bracket on the building.
• a tilting such that the guide (seen in cross section) punctually or (seen three-dimensionally) along a line on the profile is applied and high loads can arise here.
• This can be avoided by a pivotable provided on the guide guide jaw in an advantageous manner.
• the guide shoe may be provided on a lifting drive of the climbing system.
• the guide shoe may also be attachable to a wall shoe attached to the structure, and / or a scaffolding unit of the climbing system may be guidable on the guide shoe.

• To the scaffold unit is to emphasize that this invention must have only in a plane bearing profiles.
• the scaffolding unit can be made particularly simple and easy, that only a plane is provided with supporting profiles, which can be located in particular close to the building to the forces and moments occurring due to the entry of the Vertical forces in the building to keep low.
• the scaffold unit In the guides in which the scaffold unit can be guided and / or suspended, it may be, for example, attached to the building wall shoe. In particular, it is currently preferred to make the scaffold unit suspendable in an upper area on the building. In a lower region, the guidance can take place on a so-called guide shoe, which can be attachable, for example, to another wall shoe and which is to be regarded as part of the lifting drive described below.
• the self-climbing system has at least one lifting drive which can be attached directly to punctual supports on the building.
• the drive forms a single further, second vertical plane adjacent to the vertical plane of the supporting profiles of the scaffolding unit.
• the drive has no elements which extend in the stroke direction parallel to each other.
• the desired climbing can be accomplished efficiently by, for example, not requiring a crane to raise either the scaffolding unit or the existing drives.
• the lifting drive acts only in the first operating mode between the provided on the building brackets and the scaffolding unit, while it is expanded in a second mode and raised by being moved by workers in a higher range ,
• the advantage of the invention manifests itself in that the drive can be kept so small and light that this process is carried out by workers with reasonable effort.
• climbing cams offer the necessary surfaces in a simple structure, which are required for the support in the respective lifting operation. It is to be noted, however, that the invention can also be realized with engaging portions which are designed as depressions, as openings, for example in a perforated profile, as projections, for example on a rack, or in any other way.
• This offers advantages in that the lifting drive as a whole is separable from the scaffolding unit and thus can be brought by hand, for example, in a higher range. This allows a so-called semi-hydraulic operation, in which only takes place when lifting the scaffold unit operation of the linear actuators.
• by removable lifting drives in a favorable manner a combination with an operation is conceivable in which the lifting of the scaffolding unit is at least partially by a crane.
• the disengagement of the guide from the scaffold unit makes it possible to remove the drive from the scaffolding unit, in particular when it extends with one or more profiles in the region of the guide.
• the pawl or the support pin in the first mode is subjected to gravitational force and spring-loaded in the second mode.
• This can of course also be performed vice versa, so that the pawl or the support pin is spring-loaded in the first mode and subjected to gravitational force in the second mode or gravitationally applied in both modes or spring-loaded in both modes.

• separate latches and / or support bolts may be provided for the first or second mode.
• At least one guide contour which has a lower flat and / or an upper steep portion.
• the upper steep section allows the use of a gravity-loaded support pin, which falls rapidly in this area due to the steep formation of the guide contour down.
• a lower flat area advantageously makes it possible to easily deflect the support bolt, which is required when the climbing cams of the scaffold unit, as described in more detail below with reference to the drawings, have to pass by the support bolt, which happens because the latter is deflected at least for a short time become.
• a single pawl or a single carrier pin in such a way that both operating modes are made possible.
• at least one pawl is provided, which is preferably locked in the first mode and serves in the second mode that the drive "pulls" by a support means of the pawl on the scaffold unit.

• the scaffolding unit has at least one prestressable support in an area remote from the structure. This support can bias the scaffolding unit "towards the structure” and keep the otherwise occurring deformation due to the forces acting low.
