Definitions
- the present invention relates to an anchoring device for connecting manufactured components for the construction of buildings.
- anchoring devices for performing the connection between two manufactured components constituted for example by a prefabricated infilling panel made of reinforced concrete and by a beam made of reinforced concrete or steel.
- the anchoring devices of a first type comprise a first anchoring insert, constituted generally by a profile made of steel that is designed to be embedded partially in a first manufactured component, for example a prefabricated panel made of reinforced concrete, and a second anchoring insert, similar to the first one, which is designed to be embedded partially in a second manufactured component, for example a beam made of reinforced concrete. If the two manufactured components to be connected are constituted by an infilling panel and a beam, the first anchoring insert is arranged vertically in the panel, while the second anchoring insert is arranged horizontally in the beam.
- the two anchoring inserts and thus the two manufactured components, are connected to each other by means of connections with screws and bolts which engage anchoring seats formed in the anchoring inserts which can be accessed from outside through a slot-like access opening defined in a wall of the corresponding anchoring insert that is exposed in the corresponding manufactured component.
- the first anchoring insert is engaged by a first linking element, which has a plate-like body that is crossed by a slot and has, proximate to one of its sides, an anchor-like or hammer-like head that can be inserted in the anchoring seat through the access opening and can rotate about its own axis through an angle of 90° so as to abut, with the two wings of the hammer-shaped head, against the inner side of the wall of the first anchoring insert that is crossed by the access opening.
- a first linking element which has a plate-like body that is crossed by a slot and has, proximate to one of its sides, an anchor-like or hammer-like head that can be inserted in the anchoring seat through the access opening and can rotate about its own axis through an angle of 90° so as to abut, with the two wings of the hammer-shaped head, against the inner side of the wall of the first anchoring insert that is crossed by the access opening.
- the second insert is engaged by a screw with an anchor-like or hammer-like head, which can be inserted in the anchoring seat through the access opening and can rotate about its own axis through an angle of 90° so as to abut, with the two wings of the hammer-shaped head, against the inner side of the wall of the second anchoring insert that is crossed by the access opening.
- the shank of the screw is inserted through the slot defined in the plate-like body of the first linking element and, by means of a nut coupled to said screw, the plate-like body of the first linking element is fastened against the second anchoring insert or against the second manufactured component.
- a small plate with a knurling which engages a corresponding knurling formed on the face of the plate-like body face against which it rests, is generally interposed between the plate-like body of the first linking element and the second anchoring insert.
- Anchoring devices of a second type comprise an anchoring insert, constituted generally by a steel profile designed to be partially embedded in a first manufactured component, for example a prefabricated panel made of reinforced concrete, and a connecting element, which can engage the anchoring insert and can be fixed to a second manufactured component, constituted for example by a beam.
- the anchoring insert is constituted by a steel profile in which an anchoring seat is provided that can be accessed from outside through an access opening which passes through a wall of the anchoring insert that is exposed in the first manufactured component.
- an anchoring seat In such anchoring seat a block or a threaded nut is provided which faces with its threaded hole said access opening and abuts against the inner face of the wall in which the access opening is defined.
- the linking element has a plate-like portion and a threaded shank portion that extends from one side of the plate-like portion.
- a locking nut is arranged on said threaded shank.
- the linking element transmits both forces that are oriented at right angles to the wall in which the opening for access to the anchoring seat is defined and forces that are oriented at right angles to them, i.e., parallel to the wall in which the opening for access to the anchoring seat is defined. For this reason, the linking element is subjected both to traction-compression stresses and to shear stresses.
- the aim of the present invention is to solve the problem described above, by providing an anchoring device for connecting manufactured components for the construction of buildings which, with equal space occupation, can have an increased shear strength with respect to the anchoring devices of the known type.
- an object of the invention is to provide an anchoring device that is structurally simple and can be manufactured at competitive costs.
- Another object of the invention is to provide an anchoring device that is easy and quick to assemble.
- an anchoring device for connecting manufactured components for the construction of buildings, comprising an anchoring insert, which can be jointly associated with a first manufactured component and defines an anchoring seat which can be accessed from the outside of said first manufactured component through an access opening defined in a wall of said anchoring insert, and a linking element, which can engage said anchoring insert and can be associated with a second manufactured component, characterized in that said linking element comprises a first connecting element, which can be inserted with one of its portions in said anchoring seat through said access opening and can be locked with respect to said anchoring insert at least along a first direction which is substantially perpendicular to said wall of the anchoring insert for the transmission at least of forces oriented substantially along said first direction from said first manufactured component to said second manufactured component or vice versa, and a second connecting element, which can engage said anchoring insert and is adapted to transmit forces oriented along at least one second direction which is substantially perpendicular to said first direction from said first manufactured component to said second manufactured component or vice versa, and a second connecting element, which can engage said anchoring insert

Description
- The present invention relates to an anchoring device for connecting manufactured components for the construction of buildings.
- In the field of the construction of buildings, anchoring devices are known for performing the connection between two manufactured components constituted for example by a prefabricated infilling panel made of reinforced concrete and by a beam made of reinforced concrete or steel.
- Currently commercially available anchoring devices can be divided substantially into two types.
- The anchoring devices of a first type comprise a first anchoring insert, constituted generally by a profile made of steel that is designed to be embedded partially in a first manufactured component, for example a prefabricated panel made of reinforced concrete, and a second anchoring insert, similar to the first one, which is designed to be embedded partially in a second manufactured component, for example a beam made of reinforced concrete. If the two manufactured components to be connected are constituted by an infilling panel and a beam, the first anchoring insert is arranged vertically in the panel, while the second anchoring insert is arranged horizontally in the beam. The two anchoring inserts, and thus the two manufactured components, are connected to each other by means of connections with screws and bolts which engage anchoring seats formed in the anchoring inserts which can be accessed from outside through a slot-like access opening defined in a wall of the corresponding anchoring insert that is exposed in the corresponding manufactured component. More particularly, the first anchoring insert is engaged by a first linking element, which has a plate-like body that is crossed by a slot and has, proximate to one of its sides, an anchor-like or hammer-like head that can be inserted in the anchoring seat through the access opening and can rotate about its own axis through an angle of 90° so as to abut, with the two wings of the hammer-shaped head, against the inner side of the wall of the first anchoring insert that is crossed by the access opening.
- The second insert is engaged by a screw with an anchor-like or hammer-like head, which can be inserted in the anchoring seat through the access opening and can rotate about its own axis through an angle of 90° so as to abut, with the two wings of the hammer-shaped head, against the inner side of the wall of the second anchoring insert that is crossed by the access opening. The shank of the screw is inserted through the slot defined in the plate-like body of the first linking element and, by means of a nut coupled to said screw, the plate-like body of the first linking element is fastened against the second anchoring insert or against the second manufactured component. A small plate with a knurling, which engages a corresponding knurling formed on the face of the plate-like body face against which it rests, is generally interposed between the plate-like body of the first linking element and the second anchoring insert.
- Anchoring devices of a second type, particularly widespread on the US market, comprise an anchoring insert, constituted generally by a steel profile designed to be partially embedded in a first manufactured component, for example a prefabricated panel made of reinforced concrete, and a connecting element, which can engage the anchoring insert and can be fixed to a second manufactured component, constituted for example by a beam. The anchoring insert is constituted by a steel profile in which an anchoring seat is provided that can be accessed from outside through an access opening which passes through a wall of the anchoring insert that is exposed in the first manufactured component. In such anchoring seat a block or a threaded nut is provided which faces with its threaded hole said access opening and abuts against the inner face of the wall in which the access opening is defined. The linking element has a plate-like portion and a threaded shank portion that extends from one side of the plate-like portion. A locking nut is arranged on said threaded shank. In such anchoring devices, the linking element, after being inserted with its threaded shank in the anchoring seat through the access opening and after being screwed into the block or threaded nut, is locked with respect to the anchoring insert by tightening of the locking nut against the outer face of the wall in which the access opening is defined and its plate-like portion is fixed, generally by welding, directly to the second manufactured component if it is made of steel or to an element made of steel embedded previously in the body of the second manufactured component, if it is made of reinforced concrete.
- In devices of the known type, transmission of the forces between the two manufactured components mutually connected by such devices occurs exclusively by means of the linking element, both when it connects directly the two manufactured components, as in the devices that belong to the second type mentioned above, and when it connects the two manufactured components by means of another linking element, as in the devices that belong to the first type of device.
- In particular, the linking element transmits both forces that are oriented at right angles to the wall in which the opening for access to the anchoring seat is defined and forces that are oriented at right angles to them, i.e., parallel to the wall in which the opening for access to the anchoring seat is defined. For this reason, the linking element is subjected both to traction-compression stresses and to shear stresses.
- Therefore, in order to obtain an adequate mechanical strength in the connection between two manufactured components, with anchoring devices of the known type it is necessary to increase adequately the dimensions of the linking element, in particular of the region thereof, constituted usually by a threaded portion, that passes through the access opening, with the consequence of an oversizing also of the other components of the device, with increases in space occupation and in production costs.
- The aim of the present invention is to solve the problem described above, by providing an anchoring device for connecting manufactured components for the construction of buildings which, with equal space occupation, can have an increased shear strength with respect to the anchoring devices of the known type.
- Within this aim, an object of the invention is to provide an anchoring device that is structurally simple and can be manufactured at competitive costs.
- Another object of the invention is to provide an anchoring device that is easy and quick to assemble.
- This aim and these and other objects that will become better apparent hereinafter are achieved by an anchoring device for connecting manufactured components for the construction of buildings, comprising an anchoring insert, which can be jointly associated with a first manufactured component and defines an anchoring seat which can be accessed from the outside of said first manufactured component through an access opening defined in a wall of said anchoring insert, and a linking element, which can engage said anchoring insert and can be associated with a second manufactured component, characterized in that said linking element comprises a first connecting element, which can be inserted with one of its portions in said anchoring seat through said access opening and can be locked with respect to said anchoring insert at least along a first direction which is substantially perpendicular to said wall of the anchoring insert for the transmission at least of forces oriented substantially along said first direction from said first manufactured component to said second manufactured component or vice versa, and a second connecting element, which can engage said anchoring insert and is adapted to transmit forces oriented along at least one second direction which is substantially perpendicular to said first direction from said first manufactured component to said second manufactured component or vice versa as an alternative to, or in combination with, said first connecting element.
