Description

ANCHORING DEVICE FOR CONNECTING MANUFACTURED COMPONENTS FOR THE CONSTRUCTION OF BUILDINGS
Technical field
The present invention relates to an anchoring device for connecting manufactured components for the construction of buildings.
Background art
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. Disclosure of the invention
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.

Ways of carrying out the invention
With reference to the figures, the device according to the invention, generally designated in the different embodiments by the reference numerals la, lb, lc, Id, comprises an anchoring insert 2, which can be associated jointly with a first manufactured component 3 and defines an anchoring seat 4, which can be accessed from the outside of the first manufactured component 3 through an access opening 5 defined in a wall 6 of the anchoring insert 2, and a linking element 7a, 7b, 7c, 7d, which can engage the anchoring insert 2 and can be associated with a second manufactured component 8.
According to the invention, the linking element 7a, 7b, 7c, 7d comprises a first connecting element 9a, 9b, 9c, 9d, which can be inserted with one of its portions in the anchoring seat 4 through the access opening 5 and can be locked with respect to the anchoring insert 2 along at least a first direction, indicated by the arrow 10, which is substantially perpendicular to the wall 6 of the anchoring insert 2 so as to actuate the transmission of at least forces oriented substantially along said first direction 10 from the first manufactured component 3 to the second manufactured component 8 or vice versa, and a second connecting element 1 1a, l ib, 11c, l id, which can engage the anchoring insert 2 and is adapted to transmit forces oriented substantially along at least one second direction, indicated by the arrow 12, which is substantially perpendicular to the first direction 10, from the first manufactured component 3 to the second manufactured component 8 or vice versa as an alternative to, or in combination with, the first connecting element 9a, 9b, 9c, 9d.
More particularly, the anchoring insert 2 is constituted preferably, in a manner known per se, by a channel-shaped profile which defines, in its interior, the anchoring seat 4 and can be embedded at least partially, in a manner known per se, in the first manufactured component 3, which is constituted, for example, by an infilling panel made of reinforced concrete. The anchoring insert 2 can be constituted by a profile made of steel of the known type commonly known as "slot", provided with lateral openings 13 that can be used to perform its anchoring, directly or with the aid of further anchoring elements of a known type and not shown, in the concrete that constitutes the body of the first manufactured component 3. At least during the embedding of the anchoring insert 2, the anchoring seat 4 is protected adequately to be prevented from being blocked by the concrete.
In the illustrated embodiments, the profile that constitutes the anchoring insert 2 has, in transverse cross-section, a substantially Ω-like (omega-like) shape and the wall 6 is formed by two portions of the profile which are substantially bent in a C-like shape and face each other so as to define between them the access opening 5, but the shape of the anchoring insert 2 may be also different from the one shown, according to the requirements.
The anchoring insert 2 is embedded in the body of the first manufactured component 3 so that the wall 6 is arranged with its outer face flush or nearly flush with the face of the first manufactured component 3 to be directed toward the second manufactured component 8.
The access opening 5 is constituted by a slot 14, which passes through the wall 6 and, in the illustrated embodiments, runs along the entire length of the profile that constitutes the anchoring insert 2.
The second connecting element 1 1a, l ib, 1 1c, l id has an engagement portion or nose 15a, 15b, 15c, 15d, which can be inserted in the slot 14 and can engage by resting against the two mutually facing larger sides that laterally delimit the slot 14. Indeed thanks to the resting of the engagement portion or nose 15a, 15b, 15c, 15d against the sides that laterally delimit the slot 14, the second connecting element 1 1a, l ib, 11c, l id transmits forces oriented substantially along the second direction 12 from the first manufactured component 3 to the second manufactured component 8 or vice versa.
Conveniently, the second connecting element 11a, l ib, 1 1c, l id has contact shoulders 30a, 30b, 30c, 30d, which can engage the outer face of the wall 6 of the anchoring insert 2 that is crossed by the slot 14. The engagement portion or nose 15a, 15b, 15c, 15d protrudes from the supporting surface defined by the contact shoulders 30a, 30b, 30c, 30d, so as to penetrate into the slot 14, as will become better apparent hereinafter.
Advantageously, as illustrated in the different embodiments, the second connecting element 1 1a, l ib, 1 1c, l id has a portion that is designed to be connected to the second manufactured component 8 and is connected to the anchoring insert 2 by means of the first connecting element 9a, 9b, 9c, 9d.
More particularly, the first connecting element 9a, 9b, 9c, 9d passes through a through hole 16a, 16b, 16c, 16d, which is defined in an abutment portion 17a, 17b, 17c, 17d of the second connecting element 1 1a, l ib, 1 1c, l id, which can be rested against the outer face of the wall 6 of the anchoring insert 2 that is crossed by the slot 14. The abutment portion 17a, 17b, 17c, 17d defines, with its face to be directed toward the first manufactured component 3 and from which the engagement portion or nose 15a, 15b, 15c, 15d extends, the contact shoulders 30a, 30b, 30c, 30d cited above.
The anchoring insert 2, due to its shape, defines, laterally to the slot
14, contact undercuts 18, 19 for an element for locking the first connecting element 9a, 9b, 9c, 9d.
More particularly, in the first embodiment, illustrated in Figures 1 to 4, the first connecting element 9a comprises a screw 21a with an anchor- shaped or hammer-shaped head, which constitutes the locking element cited above and can be inserted, by arranging the two wings of the head parallel to the longitudinal extension of the slot 14, through the slot 14, in the anchoring seat 4, and can rotate about the axis of the screw 21a through an angle of substantially 90° so that the two wings of the head face the contact undercuts 18, 19. With the head of the screw 21a in this position, the threaded shank of the screw 21a protrudes from the anchoring seat 4 through the slot 14 and passes through the through hole 16a defined in the abutment portion 17a of the second connecting element 1 la. An external nut 20a is coupled with the threaded shank of the screw 21a and abuts against the outer face of the anchoring insert 2 with the interposition of the abutment portion 17a of the second connecting element 1 1a. In this embodiment, the engagement portion 15a is provided as a continuation of the abutment portion 17a along the axis of the through hole 16a that passes through both of these portions 15a and 17a of the second connecting element 1 1a.
In practice, in the first embodiment of the device according to the invention, the tightening of the external nut 20a along the threaded shank of the screw 21a causes the engagement of the anchor-shaped or hammer- shaped head of the screw 21a against the contact undercuts 18, 19 of the anchoring insert 2 and the tightening of the abutment portion 17a between the external nut 20a and the outer face of the wall 6 in which the slot 14 is formed. In this condition, the engagement portion 15a is inserted in the slot 14. With the device thus assembled, the screw 21a, which together with the external nut 20a constitutes the first connecting element 9a, transmits mainly forces that are oriented along the first direction 10 from the first manufactured component 3 to the second manufactured component 8 or vice versa, while the engagement portion or nose 15a of the second connecting element 1 la transmits forces that are oriented along the second direction 12 from the first manufactured component 3 to the second manufactured component 8 or vice versa. Substantially, the screw 21a is subjected mainly to traction-compression stresses, while the engagement portion 15a of the second connecting element 1 la is subjected to shearing stresses.
In this first embodiment, the portion of the second connecting element 11a that is designed to be connected to the second manufactured component 8 is shaped so as to have two coplanar wings 22a, which divaricate progressively starting from the abutment portion 17a toward the second manufactured component 8. Such wings 22a may be fixed to the second manufactured component 8 by welding, as shown, or by way of other fixing means of a known type.
In the second embodiment, illustrated in Figures 5 to 8, the locking element of the first connecting element 9b is constituted by an internal nut or block 23b, which is arranged inside the anchoring seat 4 and rests against the contact undercuts 18, 19 defined by the inner face of the wall 6. As illustrated, the internal nut 23b is pushed against the contact undercuts 18, 19 by a spring 24b that is interposed between said internal nut 23b and the wall of the anchoring insert 2 that lies opposite the wall 6. The first connecting element 9b comprises a screw 21b with a head having a larger diameter in which a recessed hexagon-shaped seat is defined. Such screw 21b passes through the through hole 16b, which is defined in the abutment portion 17b of the second connecting element l ib, and is coupled to the threaded hole of the internal nut 23b, arranged at the slot 14. The head of the screw 21b, which is accommodated in a seat 25b defined in the abutment portion 17b, abuts against the outer face of the wall 6 of the anchoring insert 2 with the interposition of the abutment portion 17b. In this second embodiment, too, the engagement portion 15b is provided as a continuation of the abutment portion 17b along the axis of the through hole 16b that passes through both of these portions 15b, 17b of the second connecting element 1 lb.
In practice, in the second embodiment of the device according to the invention, the tightening of the screw 21b causes the internal nut or block 23b to engage the contact undercuts 18, 19 of the anchoring insert 2 and the tightening of the abutment portion 17b between the head of the screw 21b and the outer face of the wall 6 in which the slot 14 is provided. In this condition, the engagement portion 15b is inserted in the slot 14. With the device thus assembled, the screw 21b, which together with the internal nut or block 23b constitutes the first connecting element 9b, transmits mainly forces that are oriented along the first direction 10 from the first manufactured component 3 to the second manufactured component 8 or vice versa, whereas the engagement portion or nose 15b of the second connecting element l ib transmits forces that are oriented along the second direction 12 from the first manufactured component 3 to the second manufactured component 8 or vice versa. Substantially, the screw 21b is subjected mainly to traction-compression stresses, whereas the engagement portion 15b of the second connecting element l ib is subjected to shearing stresses.
In this second embodiment, too, the portion of the second connecting element l ib that is designed to be connected to the second manufactured component 8 is shaped so as to have two coplanar wings 22b, which divaricate progressively starting from the abutment portion 17b toward the second manufactured component 8.
Such wings 22b may be fixed to the second manufactured component 8 by welding, as shown, or by way of other fixing means of a known type.
In the third embodiment, illustrated in Figures 9 to 1 1, similarly to the second embodiment, the locking element of the first connecting element 9c is constituted by an internal nut or block 23c, which is arranged inside the anchoring seat 4 and rests against the contact undercuts 18, 19 that are defined by the inner face of the wall 6. The internal nut 23c is pushed against the contact undercuts 18, 19 by a spring 24c, which is interposed between the internal nut 23 c and the wall of the anchoring insert 2 that lies opposite to the wall 6. The first connecting element 9c comprises a screw 21 c with a head having an enlarged diameter, in which there is a flush hexagon-shaped seat. Said screw 21c passes through the through hole 16c, which is provided in the abutment portion 17c of the second connecting element 1 1c, and engages the threaded hole of the internal nut 23c, which is arranged at the slot 14. The head of the screw 21c, which is accommodated in a seat 25c that is provided in the abutment portion 17c, abuts against the outer face of the wall 6 of the anchoring insert 2 with the interposition of the abutment portion 17c.
Differently from the second embodiment, in this third embodiment the engagement portion 15c is spaced from the abutment portion 17c along a direction which is parallel to the longitudinal extension of the slot 14.
In practice, in the third embodiment of the device according to the invention, the tightening of the screw 21c causes the engagement of the internal nut or block 23c against the contact undercuts 18, 19 of the anchoring insert 2 and the tightening of the abutment portion 17c between the head of the screw 21c and the outer face of the wall 6 in which the slot 14 is provided. In this condition, the engagement portion 15c is inserted in the slot 14. With the device thus assembled, the screw 21c, which together with the internal nut 23c constitutes the first connecting element 9c, transmits forces that are mainly oriented along the first direction 10 from the first manufactured component 3 to the second manufactured component 8 or vice versa, whereas the engagement portion or nose 15c of the second connecting element 1 1 c transmits forces that are oriented along the second direction 12 from the first manufactured component 3 to the second manufactured component 8 or vice versa. Substantially, the screw 21c is subjected mainly to traction-compression stresses, whereas the engagement portion 15c of the second connecting element 11c is subjected to shearing stresses.
In the third embodiment, too, the portion of the second connecting element 11c that is designed to be connected to the second manufactured component 8 is shaped so as to define two coplanar wings 22c, which divaricate progressively starting from the abutment portion 17c toward the direction of the second manufactured component 8. Such wings 22c may be fixed to the second manufactured component 8 by welding, as illustrated, or by way of other fixing means of a known type.
In the fourth embodiment, illustrated in Figures 12 to 21, the first connecting element 9d comprises a screw 21d with an anchor- or hammer- shaped head, which constitutes the locking element cited above and, by arranging the two wings of the head parallel to the longitudinal extension of the slot 14, can be inserted, through the slot 14, in the anchoring seat 4 and can rotate about the axis of the screw 2 Id through an angle of substantially 90° so that the two wings of the head face the contact undercuts 18, 19. With the head of the screw 21d in this position, the threaded shank of the screw 21d protrudes from the anchoring seat 4 through the slot 14 and passes through the through hole 16a provided in the abutment portion 17d of the second connecting element l id. An external nut 20d mates with the threaded shank of the screw 21d and abuts against the outer face of the wall 6 of the anchoring insert 2 with the interposition of the abutment portion 17d of the second connecting element l id. In this embodiment, too, similarly to the third embodiment, the engagement portion 15d is spaced from the abutment portion 17d along a direction which is parallel to the longitudinal extension of the slot 14.
In practice, in the fourth embodiment of the device according to the invention the tightening of the external nut 20d along the threaded shank of the screw 2 Id causes the anchor-shaped or hammer-shaped head to engage the contact undercuts 18, 19 of the anchoring insert 2 and the tightening of the abutment portion 17d between the outer nut 20d and the outer face of the wall 6 in which the slot 14 is provided. In this condition, the engagement portion 15d is inserted in the slot 14. With the device thus assembled, the screw 2 Id, which together with the external nut 20d constitutes the first connecting element 9d, transmits mainly forces that are oriented along the first direction 10 from the first manufactured component 3 to the second manufactured component 8 or vice versa, whereas the engagement portion or nose 15d of the second connecting element l id transmits forces that are oriented along the second direction 12 from the first manufactured component 3 to the second manufactured component 8 or vice versa. Substantially, the screw 21b is subjected mainly to traction-compression stresses, whereas the engagement portion 15d of the second connecting element 1 Id is subjected predominantly to shear stresses.
In this fourth embodiment, the portion 22d of the second connecting element l id that is designed to be connected to the second manufactured component 8 is substantially plate-shaped. The engagement portion 15d extends in a coplanar manner from the side of said plate-like portion 22d designed to face the first manufactured component 3. The abutment portion 17d extends proximate to said side of the plate-shaped portion 22d but is raised with respect to the engagement portion 15d. The plate-like portion 22d may be fixed to the second manufactured component 8 by means of welding, as shown, or by way of other fixing means of a known type.
For the sake of completeness in description, it must be noted that the wall 6 in which the slot 14 is provided can have, in a manner known per se, knurlings or teeth, as shown in the different embodiments.
The device according to the invention is installed so as to mutually connect two manufactured components 3, 8 by making the first connecting element 9a, 9b, 9c, 9d engage the second connecting element 11a, l ib, 1 1c, l id and thus the anchoring insert 2 previously embedded in the first manufactured component 3. In this manner, the second connecting element 1 1a, l ib, 11c, l id is firmly connected to the anchoring insert 2 and thus to the first manufactured component 3 by means of the first connecting element 9a, 9b, 9c, 9d. The second connecting element 1 1a, l ib, 11c, 1 Id is then fixed to the second manufactured component 8 by welding or by way of other fixing means of a known type, by connecting to each other the two manufactured components 3 and 8.
If, as in most cases, the first manufactured component 3 is constituted by an infilling panel, the anchoring insert 2 is embedded in the first manufactured component 3 with the longitudinal axis of the slot 14 arranged substantially vertically and the plane of arrangement of the portion of the second connecting element 1 1 a, l ib, 1 1c, l id, which is shaped like a plate or so as to define two wings 22a, 22b, 22c, 22d and designed to be connected to the second manufactured component 8, is arranged on a substantially horizontal plane.
In practice it has been found that the anchoring device according to the invention fully achieves the intended aim, since due to the fact that the linking element is composed of a first connecting element designed to be subjected predominantly to traction-compression stresses and a second connection element, in addition to the first connecting element and designed to be subjected predominantly to shearing stresses, with a space occupation equal to that of anchoring devices of a known type, has a greater resistance to shearing stresses.
The anchoring device thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims; all the details may further be replaced with other technically equivalent elements.
In practice, the materials used, although the use of steel is preferred, as well as the dimensions, may be any according to requirements and to the state of the art.
