Description

Technical field of the invention

The present invention relates to an anchoring and storage system for a component, in particular a first component designed as a stair landing, for connecting the same to a second component designed as a building wall and / or another building structure. A structural element can generally be understood to mean an element to be connected to a building structure or other structure, which element is, for example, a prefabricated concrete component. Furthermore, the invention relates to a method for connecting the first component, designed as a stair landing, to the second component, designed as a building body.

State of the art

In stair construction it is known to use stair components as prefabricated concrete components or as concrete components made from in-situ concrete on the construction site, which are joined together to form a flight of stairs on at least one building wall or another building structure. Corresponding components include stair landings, used as intermediate or turning landings and / or main landings at the entry and / or exit of the flight of stairs, as well as flight of stairs elements, which are connected to the wall of a stairwell or stairwell or a floor ceiling, taking into account sufficient sound insulation. Prefabricated stair landings used as visible parts are embedded and placed in the generally spatially limited stairwell, the walls of which are often made of reinforced concrete or built as masonry.

For anchoring a component designed as a prefabricated stair component to a building, for example a wall, a connection and bearing system is known, comprising a mandrel sleeve and a mandrel, also referred to as a mandrel-like carrier or force introduction element. A recess is formed on a surface of the wall referred to as the second connection surface Manufactured in a suitable position, for example designed as a recess when concreting the same, which is designed to receive a mandrel. The mandrel can be slipped onto or onto a short sleeve in order to be able to be positioned and held in the receptacle. The first component to be connected, for example the prefabricated stair component, has on a first connection surface a mandrel sleeve matched to the mandrel-like carrier in the appropriate position and orientation, which can be cast in when the component is manufactured. For anchoring, the precast stair component is positioned relative to the building body, so that the spike-like carrier can be at least partially inserted through the recess on the first connection surface into the mandrel sleeve of the precast stair component. The recess with the mandrel received therein is then filled with a suitable solidifying compound.

With such a connection and storage system, designed as a mandrel sleeve and mandrel, the components to be connected must be brought into position and held relative to one another, which must also be maintained during filling in order to avoid inhomogeneity during filling. A precast stair component is generally a landing, a floor slab or a staircase element that is to be connected to a building structure. Since the weight of the components to be positioned relative to one another is high and the space in a stairwell is limited, the positioning and orientation of the component to be connected proves to be difficult. In addition, the small size of the mandrel and opening of the mandrel sleeve makes it difficult to insert the components of the known anchoring and storage system into one another.

For height adjustability, a level regulating device is known in connection with the mandrel sleeve and mandrel, which is set up to support, for example, a stair flight element on a stair landing in a height-adjustable manner.

Furthermore, sound insulation is a key issue in the construction of a stairwell. Accordingly, measures must be taken that do not transmit impact sound through the walls. The use is known an impact sound insulation in the form of an elastomer layer, which provides a sound decoupling between the components to be connected.

The known anchoring and storage systems for connecting and supporting either a staircase element on a stair landing or on a floor and a stair landing on a wall or a floor are very complex and require a sufficient material thickness in the connection area. This is not a problem with conventional concrete components in which tensile stresses are absorbed by reinforcement. However, problems arise with a slim concrete structure, for example with a staircase element in the form of a so-called folded structure, in which reinforcement can be dispensed with by using ultra-high-strength fiber-reinforced concrete, in conjunction with a conventional connection and storage system.

Summary of the invention

The object of the invention is to provide an anchoring and storage system for a structural element which is a further development of a conventional anchoring and storage system. The further developed anchoring and storage system allows a stair landing to be easily connected to a building structure, e.g. a stairwell wall, and is universally suitable for anchoring both a slim and a thick embodiment of the component. Furthermore, impact sound insulation can easily be integrated into the further developed anchoring and storage system.

These objects are achieved by an anchoring and storage system for a component according to claim 1 and a method for connecting the component to a further component according to claim 12. Advantageous further developments of the invention are the subject of the dependent claims.

The anchoring and storage system according to the invention for a first component is designed to connect the first component to a second component. For this purpose, at least one force introduction element and a receptacle are provided, in which the at least one force introduction element can be received. The connection of the components should transfer loads from the first component to the second component over a component joint. Furthermore, relative displacements should be tolerable to a certain extent. Accordingly, the anchoring and storage system is designed to allow movement in the longitudinal direction of the at least one force introduction element and transversely to the longitudinal direction.

The anchoring and storage system according to the invention accordingly comprises at least one receptacle as a first component. The at least one force introduction element as a second component is provided on the second component in a protruding manner on a second connection surface. Both components are designed to be complementary to one another to a certain extent.

According to the invention, the receptacle on a first connection surface on the first component is designed as a groove, i.e. in the manner of a groove. The groove extends along a longitudinal direction in the first connection surface. The groove is open to the first connection surface, so that the at least one force introduction element can at least partially be introduced and slidably received along the groove.

In one embodiment, the first component is designed as a stair landing, in particular a prefabricated stair component, which can be connected to at least one staircase wall or to a floor ceiling, the second component, by means of the anchoring and storage system. However, it is also conceivable that the anchoring and storage system can be used to connect a stairway element to a stair landing or a floor.

The at least one force introduction element can be designed as a mandrel which can be fastened in a recess made in the second component. Accordingly, as already known, the mandrel can be plugged into or fitted onto a sleeve in the recess of the second component and anchored or fastened therein by means of a solidifying compound. Alternatively, the at least one force introduction element can be designed as a rib on one of the connection surfaces of the components to be connected to one another. The at least one force introduction element, designed as a cantilevered rib or as a mandrel, attached to or inserted into a sleeve, can have a square cross-section.

In one embodiment, the groove formed for receiving the at least one force introduction element can be formed by a guide rail which is arranged in the first connection surface and connected in the first component. The guide rail can for example be made of a metal as a bent part and is placed and anchored directly when the first component is cast.

In a further embodiment of the anchoring and bearing system it is provided that means for transmitting force, which are referred to as reinforcing elements, are provided in the first component for the transmission of force, in particular transverse forces. The at least one reinforcement element is arranged in particular in an area on the receptacle in which the at least one force introduction element introduced into the groove is positioned and held in an end position.

The at least one reinforcement element is held in a clamping manner at a closed end of the groove. For this purpose, it comprises two plates which can be connected to one another and are arranged parallel to one another and which span a space between them in which the closed end of the groove is at least partially accommodated. The parallel plates can have a trapezoidal shape, with the wide end of the trapezoidal shape being oriented in the direction of receiving the groove, and so surfaces suitable for mounting are sufficiently available. The space for receiving the groove is further limited by a first intermediate plate which is arranged parallel to one another Connects plates together and is arranged perpendicular to these. In addition to the first intermediate plate, one or more connecting elements are provided between the parallel plates in different embodiments outside the receiving space for the groove. For example, one of the connecting elements is designed as a screw connection. Alternatively, in addition or as an alternative to the screw connection, one or more intermediate plates can be provided which are arranged parallel or largely perpendicular to the first intermediate plate in the space between the parallel plates. In order to connect the reinforcing element to the first structural element, for example, when the first structural element is to be cast in as a concrete structural part, openings can be provided on the reinforcing element for better concreting.

In a preferred embodiment of the anchoring and storage system, means are provided for sound insulation, in particular impact sound insulation. The means for sound insulation effect a sound decoupling between the interconnected components. A sound-absorbing material which can be arranged at least on contact surfaces between the at least one force introduction element and the groove is suitable for impact sound insulation. Suitable materials are, for example, a closed-cell elastomer which can be used in the form of a full-surface mounting or in the form of a strip-like and / or point-like mounting between the at least one force transmission element and the groove.

The method for anchoring and mounting a building element by means of the anchoring and mounting system according to the invention can be used to connect a stair landing to a building wall. This includes steps for providing a first component with a receptacle on a first connection surface, which is designed as a groove, reinforcing elements being provided as means for force transmission into the first component, and for providing a second component with at least one force introduction element which is so arranged is that it protrudes over a second pad. Furthermore, a positioning of the first component relative to the second component is included, so that the at least one force introduction element is at least partially inserted into the groove is, and moving the first component relative to the second component in an end position.

It may be necessary for the at least one force introduction element to be adjusted with regard to its horizontal alignment, in order to provide in particular a flat support surface. A receptacle or a groove can be provided when the first component is cast, the groove preferably being designed as a guide rail which is cast in during the manufacture of the first component. The reinforcing elements are also placed in the first component as a means for transmitting force and anchored to the first component during the casting process.

In a further embodiment, means for soundproofing can be arranged on the groove in the areas where the at least one force introduction element finds its end position. For example, a material with sound-absorbing properties can be arranged in the form of a layer on one or more contact surfaces between the force introduction element and the groove.
