Description

“ATTACHMENT DEVICE FOR A PARAPET OR SUCHLIKE”
FIELD OF THE INVENTION
The present invention concerns an attachment device for a parapet, or suchlike. With the term“parapet” we also mean any other vertical element normally installed in the construction field and for protective purposes at the ends of an elevated horizontal plane, in particular of a structure under construction, such as a floor, a mezzanine or suchlike.
BACKGROUND OF THE INVENTION
In the construction field, different attachment devices are known to attach vertical and horizontal elements of provisional and/or definitive structures or scaffolding which support the execution of works at different heights.
In particular, it is known that to make reinforced concrete floors a support structure is normally provided consisting of a series of adjacent panels to define a single and compact horizontal plane on which to cast concrete.
Furthermore, the panels are rested on support girders.
The girders and panels defining the support structure for the construction of the floor are supported by a series of props made of steel or aluminum, or other support structure. In particular, each support girder is supported by at least one prop or other support element.
It is also known that in order to guarantee the safety of the operators who work on this support structure it is necessary to install anti-fall parapets.
Attachment devices are also known to attach the horizontal plane of the support structure of the floor and the parapets.
One known attachment device comprises a vice element to constrain the horizontal plane with the part of the parapet in contact with the horizontal plane itself. Flowever, this device is not completely safe because, for example, the vice element may not have been adequately tightened and can also loosen over time, making the parapet unstable, unsafe and at risk of detaching and falling from the horizontal plane to which, instead, it should be firmly attached.
Moreover, the known attachment devices have long installation and attachment times, and, in addition, it is not always possible to guarantee the stability of the horizontal plane to which the attachment device is anchored. Another known attachment device is provided with a support body and a screw element ending with a hook. The support body is provided with a seating in which to insert a vertical element for supporting the parapet and the support body is constrained to the horizontal plane by means of the hook that hooks onto the support girder and is clamped by screwing in this position.
This known attachment device has a long and complex hooking system and a rather dangerous installation procedure, since the installer has to remain in a precarious position, leaning from the horizontal plane, for a prolonged period of time so as to ensure the correct attachment of this device.
Another known attachment device connects to girders disposed at a fixed distance and can have an integrated parapet. This device is of limited application because it requires a fixed distance between the girders with limited and difficult operation both for the installer and also for the operator.
One purpose of the present invention is therefore to provide an attachment device for a parapet which is easy, safe and quick to install and which therefore overcomes the problems of the known attachment devices mentioned above.
Another purpose of the present invention is to provide an attachment device which guarantees a firm and secure attachment of a parapet to a horizontal plane of a support structure.
It is also a purpose of the present invention to provide a formwork system equipped with an attachment device to attach a parapet to a horizontal plane for making floors which guarantees safe and easy working conditions for an operator.
The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
SUMMARY OF THE INVENTION
The present invention is set forth and characterized in the independent claims, while the dependent claims describe other characteristics of the invention or variants to the main inventive idea.
In accordance with the above purposes, an attachment device according to the present invention can be selectively coupled to a support girder, which has a predominantly oblong development, to allow the attachment thereto of a vertical support element and/or of a parapet.
The support girder is provided, in the proximity of at least one of its head ends, with an abutment plate attached transversely to the oblong development of the support girder.
According to one aspect of the invention, the attachment device comprises a support body, provided on the top with a section bar element in which a vertical support element of the parapet can be installed and provided laterally with at least one attachment portion which defines, with the support body, at least one housing seating which can be inserted, by vertical sliding, on an abutment plate attached to a head end of a support girder and transversely with respect to the mainly oblong development of the support girder.
Thanks to this support body provided with these housing seatings which are inserted in the abutment plate of the support girder by means of a simple vertical sliding, the present attachment device advantageously has a simple, precise, stable, safe attachment mode, which can be performed rapidly and that furthermore requires a limited intervention by the operator.
According to another aspect of the invention and in order to guarantee even greater stability to the present attachment device, the support body comprises at least a pair of attachment portions made on lateral plates of the support body so as to define at least two housing seatings located at the sides of the support body and insertable on sections of the abutment plate protruding from one side and the other with respect to the support girder.
According to another aspect of the invention, an interference element is associated with the support body and is selectively able to be activated to constrain/release the retention of the attachment device on the abutment plate of the support girder. This interference element is positioned downstream of the attachment portion with respect to the vertical sliding direction.
This interference element guarantees a secure and firmly constrained connection between the support girder and the vertical support element and/or the parapet, substantially eliminating the risk of the vertical support element and/or the parapet sliding out accidentally.
Another purpose of the invention is a formwork system to support and construct floors, comprising a series of support girders configured to support at least one horizontal plane and at least one attachment device configured to attach, in a selectively releasable manner, a parapet orthogonally to the horizontal plane by means of one or more of the support girders.

The abutment plate 18 also comprises sections 36 protruding from one side and the other with respect to the support girder 13. The abutment plate 18 and the insertion body 24 therefore have a substantially T-shaped shape, as can be seen in fig. 4.
According to one embodiment, the abutment plate 18 and the insertion body 24 can be made in a single body.
According to one embodiment, the insertion body 24 can be welded to the support girder 13.
According to another embodiment, the insertion body 24 can be firmly anchored, in a selectively releasable manner, to the support girder 13.

According to another embodiment, the groove 23 can have an arcuate cross- section.
According to another embodiment, the groove 23 can have a rectangular cross- section.
According to one aspect of the present invention, the attachment device 10, see for example fig. 2, is defined by a support body 19 provided on the top with a section bar element 16 attached to the support body 19 and in which a vertical support element 17 can be installed to which the parapet 11 is connected, visible in fig. 1.
In order to connect the parapet 11 to the horizontal plane 12, at least two attachment devices 10 and, therefore, at least two vertical support elements 17 are preferably used.
The number of attachment devices 10, and therefore of vertical support elements 17, will be chosen based on the length of the parapet 11 and on the distance between the support girders 13.
According to one embodiment, the support body 19 can be provided with at least two lateral plates 33 parallel to each other.
According to another embodiment, the support body 19 can be provided with at least one connection plate 34 which connects the two lateral plates 33 together.
According to another embodiment, the connection plate 34 can join the two lateral plates 33 together by welding the connection plate 34 to the lateral plates 33.
According to another embodiment, the section bar element 16 can be positioned on the connection plate 34, therefore the connection plate 34 is positioned between the lateral plates 33 and the section bar element 16.
According to one embodiment, the section bar element 16 can be welded to the support body 19.
According to one embodiment, the section bar element 16 can be removably coupled to the support body 19 in snap-in manner.
According to one embodiment, the section bar element 16 is hollow inside and has a shape mating with the shape of the vertical support element 17.
According to one embodiment, the section bar element 16 can be provided inside with a connection and support element 27, see for example fig. 3, suitable for the selectively releasable connection with the vertical support element 17.
The connection and support element 27 can have a shape suitable to be inserted inside one end of the vertical support element 17.
According to some embodiments, the attachment between the connection and support element 27 and the vertical support element 17 and/or between the section bar element 16 and the vertical support element 17 could be of the bayonet type, the screw type, the snap-in type or suchlike.
The attachment device 10, see fig. 2, is provided laterally with at least one attachment portion 21 defining, with the support body 19, a housing seating 22 which can be inserted, by vertical sliding V, on the abutment plate 18 of the support girder 13.
According to one embodiment, the attachment portion 21 can have a hooked or similar shape suitable to allow its insertion on the abutment plate 18.
The present attachment device 10 preferably comprises at least one pair of attachment portions 21 made on the lateral plates 33 of the support body 19 and suitable to define two housing seatings 22 positioned on the sides of the support body 19 and which can be inserted on sections 36 of the abutment plate 18 protruding from one side and the other with respect to the support girder 13.
The connection between the attachment portion 21 and the abutment plate 18 prevents the downward vertical sliding V of the attachment device 10 and therefore guarantees the support of the parapet 1 1 in the vertical position with respect to the horizontal plane 12.
An interference element 20 can also be associated with the support body 19 and is selectively able to be activated in order to constrain/release the retention of the attachment device 10 on the support girder 13. In particular, the interference element 20, during use, prevents the upward vertical movement of the attachment device 10 guaranteeing a firmer and more secure attachment of the parapet 1 1 to the horizontal plane 12.
According to one embodiment, the interference element 20 can have an elongated shape suitable to be inserted in a through hole 31 provided in a support plate 30, see also fig. 3, fig. 5 or fig. 6. The support plate 30 is disposed inside the support body 19 in correspondence with the attachment portion 21.
The interference element 20 is mobile in the through hole 31 and has a certain inclination with respect to the support plate 30.
According to one embodiment, the interference element 20 can have an arcuate elongated shape.
According to one embodiment, the support plate 30 can be inserted snap-in in the support body 19.
According to another embodiment, the support plate 30 can be welded to the support body 19.
In particular, the interference element 20 can have a first end 28 suitable to be inserted in the through hole 31 and a second end 29, opposite the first end 28 with respect to the through hole 31 and, therefore, positioned inside the support body 19.
According to one embodiment, at least one element with lateral bulk 32 can be associated with the first end 28, once inserted in the through hole 31 from the inside of the support body 19 toward the outside.
The element with lateral bulk 32 could be a screw, a round piece or suchlike for example inserted transversely in a hole (not shown) provided in the first end 28.
According to one embodiment, the element with lateral bulk 32 could provide a pair of hemispherical elements or buttons disposed opposite on one side and on the other of the first end 28.
According to one embodiment, the second end 29 of the interference element 20 has a larger shape and size than the through hole 31 , so as to prevent it from passing through the through hole 31. The second end 29 can be moved away from, or toward, the through hole 31 in a rapid, quickly and safe manner by the user.
The element with lateral bulk 32 increases the lateral size of the first end 28 preventing the latter from re-entering the through hole 31 to ward the inside of the support body 19. In this way, the first end 28 protrudes from the support plate 30.
Advantageously, the groove 23, provided on the abutment plate 18, acts as a guide for the passage of the first end 28, protruding from the support plate 30, during the insertion of the attachment portion 21 onto the abutment plate 18 of the support girder 13 by vertical sliding V.
Once the attachment portion 21 has been inserted on the abutment plate 18, the first end 28 is channeled by the groove 23 below the abutment plate 18 and the second end 29 is moved toward the through hole 31 so as to thrust the first end 28 toward the support girder 13, below the abutment plate 18, blocking and constraining the upward vertical movement of the attachment device 10.
Moreover, advantageously the interference element 20 in cooperation with the groove 23 also constrains the lateral movements of the attachment device 10 with respect to the abutment plate 18. Consequently, the attachment device 10 firmly and securely constrains the parapet 11 to the horizontal plane 12.
To remove the attachment device 10 it is sufficient to move, toward the inside of the support body 19, the second end 29 up to the point where the first end 28 re-enters the groove 23 of the abutment plate 18 and then extract the attachment device 10 vertically upward.
Advantageously, the attachment device 10 decreases the installation and removal time of the parapet 11 , reducing them to a few simple and rapid steps as described above.
According to a possible variant embodiment, with reference to fig. 7, the interference element 20’ can be pivoted to the support plate 30 by means of a pin 35 disposed between the opposite vertical walls of the through hole 31 and attached thereto.
According to one embodiment, the pivoted interference element 20’ can have a substantially triangular shape.
According to another embodiment, the size of the through hole 31 is greater than the size of greater bulk of the pivoted interference element 20’.
The pivoted interference element 20’ can be provided with a slot 37 in which the pin 35 is inserted. The interference element 20’ can rotate around the pin 35 and translate along the slot 37 with respect to the pin 35.
According to one embodiment, the slot 37 can have a rectilinear longitudinal development.
According to one embodiment, the slot 37 can be made along a central plane of the interference element 20’ so as to equally distribute the weight on one side and on the other of the slot 37.
In the position of equilibrium of the interference element 20’, the slot 37 is disposed parallel to the support plate 30, as in fig. 7.
The position of equilibrium of the triangular interference element 20’ is such that the slot 37 is disposed parallel to the support plate 30 and one side of the interference element 20’ is perpendicular to the through hole 31 and protrudes symmetrically from one side and the other of the hole 31 so as to equally distribute the weight of the interference element 20’ itself.
In the operation of inserting the attachment device on the abutment plate 18 of the support girder 13, the interference element 20’ rotates around the pin 35, for example in an anti-clockwise direction observing fig. 7, while the attachment portion 21 engages the abutment plate 18.
The interference element 20’, once the attachment portion 21 has engaged the abutment plate 18, returns to the position of equilibrium stably and firmly constraining the attachment device 10 to the support girder 13.
In particular, the interference element 20’, in its position of equilibrium, advantageously blocks the upward vertical movement of the attachment device 10 guaranteeing a secure and stable connection between the device 10 and the support girder 13.
To remove the attachment device 10 with the configuration as above, it is sufficient for the operator to rotate the interference element 20’ in an anti- clockwise direction and at the same time extract the attachment device 10 upward so that the attachment portion 21 disengages the abutment plate 18.
It is clear that modifications and/or additions of parts may be made to the attachment device 10 as described heretofore, without departing from the field and scope of the present invention.
It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of attachment device 10, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
In the following claims, the sole purpose of the references in brackets is to facilitate reading and they must not be considered as restrictive factors with regard to the field of protection claimed in the specific claims.
