Description

Title of the invention: Hoisting device for panel

[0001] The present invention relates to the field of hoisting mechanisms and more particularly to the field of devices for hoisting panels intended to form a construction element.

[0002] Currently, during the movement of a panel on a construction site, it is common to use a hoisting machine which, through one or more slings, hooks the panel at one or more points of its structure and / or its framework.

[0003] The most commonly used hanging device consists of a structure including a loop and positioned at the edge or upper surface of the panel when the panel is placed in a substantially vertical plane. By way of example, in its simplest construction, the structure of the hanging device is made by a portion of the upper end of the metal framework of the panel. However, in the context of moving wooden panels without metal framework, it is complex to take advantage of the presence of any framework.

[0004] To overcome the lack of metal reinforcement in certain panels, a lifting device has been developed consisting of a metal hoop mounted on the upper surface of the panel, forming a stirrup with this upper surface. Such lifting devices are then generally mounted at each end of the panel to allow balanced lifting using slings or even a spreader beam. However, the main drawback of this technical solution is that it leaves a metal hoop anchored to the upper surface of the panel after installation, which may obstruct the upper section during subsequent construction work incorporating the panel.

[0005] The present invention aims to overcome these drawbacks by proposing a fastening device configured to be permanently mounted on a panel while being integrated into the implementation of the construction site after the installation of the panel.

[0006] The present invention relates to a panel lifting point device comprising: - an interface for attaching to at least one lifting device and / or a lifting hook, - an anchoring interface configured to cooperate with a portion of the upper part of a panel arranged in a substantially vertical plane, characterized in that the device also comprises: - a linking structure between, on the one hand, the attachment interface and, on the other hand, the anchoring interface, this linking structure comprising: - connection interfaces respectively dedicated to the attachment interface and the anchoring interface, - an interface for fixing at least one means of stopping the pouring of a concrete element at the level of an upper surface of the panel.

[0007] The invention also relates to an assembly characterized in that this assembly comprises: - a panel arranged in a roughly vertical plane, - at least one lifting point device according to the invention, the interfaces of which anchors cooperate with respective portions of the upper part of the panel, and / or - a receiving interface for a supplementary insertion portion of an element to be mounted on the device.

[0008] The invention will be better understood from the following description, which relates to preferred embodiments, given by way of non-limiting examples, and explained with reference to the accompanying schematic drawings, in which:

[0009] [Fig. 1] is a schematic illustration of an example of a lifting point device according to the invention,

[0010] [Fig.2] is a schematic illustration of an example assembly according to the invention comprising a panel associated with several lifting point devices according to the invention,

[0011] [Fig.3] is a schematic illustration according to a sectional view of an example of lifting point device according to the invention mounted on the upper part of a panel and associated with a concrete element 31.

[0012] The present invention relates to a lifting point device 1 for a panel 2 comprising: - a mounting interface 11 to at least one lifting device and / or a lifting hook, - an anchoring interface 12 configured to cooperate with a portion of the upper part of a panel 2 arranged in a substantially vertical plane, characterized in that the device 1 also comprises: - a linking structure 13 between, on the one hand, the attachment interface 11 and, on the other hand, the anchoring interface 12, this linking structure 13 comprising: - connection interfaces 131, 132 respectively dedicated to the attachment interface 11 and the anchoring interface 12, - a fixing interface 133 for at least one means of stopping the pouring of a concrete element 31 at the level of an upper surface of the panel 2, and / or - a complementary 134 receiving interface for an insertion portion of a element 4 to be mounted on device 1.

[0013] The device 1 according to the invention is thus configured to be mounted or fixed on the upper part of a panel 2, ideally its upper edge or the upper surface of this panel 2, by means of its anchoring interface 12. Preferably, this anchoring interface 12 is made in the form of a longline structure arranged substantially vertically to be inserted into the material of the panel 2 at the level of its upper part, or even to be positioned against or inside the upper part of a part of the reinforcement of the panel 2. Preferably, this anchoring interface 12 cooperates with the upper part of a vertical upright 21 of the panel 2 when the latter is positioned in a vertical plane.This cooperation may then involve means of fixing the anchoring interface 12 with one or more elements of the panel 2, such as screws or dowels mounted through the anchoring interface 12 and at least one element of the panel 2.

[0014] The attachment interface 11 of the device 1 according to the invention comprises at least one hook and / or a closed loop 111 configured to be able to cooperate with a hook and / or a sling of a lifting appliance, or even with any type of attachment means or interface used by a lifting appliance or device. This attachment interface 11 is preferably positioned at the top of the lifting point device 1 according to the invention so that, when the device 1 is positioned in the top of a panel 2, this attachment interface remains easily accessible for lifting the panel 2.

[0015] The connecting structure 13 of the device 1 according to the invention is configured to provide a junction structure between, on the one hand, the attachment interface 11 with a lifting element and, on the other hand, the anchoring interface 12 to the panel 2. The attachment interface 11 and the anchoring interface 12 are fixed to the connecting structure 13 at respective connecting interfaces 131, 132. These connecting interfaces 131, 132 may be configured as flat surfaces and / or adapted to the surfaces of elements with which they may interact. Thus, by way of example, the connecting interface 132, which carries the anchoring interface 12 to the panel 2, may have a surface shape complementary to the portion of the upper surface of the panel 2 on which the device 1 is intended to be positioned.Similarly, according to an example relating to a variant construction of the linking structure 13 of the device 1, the linking interface 131 to the attachment interface 11 and the linking interface 132 to the anchoring interface 12 are configured in substantially planar arrangements and are disposed in respective planes that are substantially parallel to each other. Such a construction thus allows a structural element to rest, at least partially, on the device 1 of the invention at the level of a . The surface is substantially parallel to the upper surface of panel 2. Therefore, when two vertical panels 2 are superimposed with one or more devices 1 according to the invention arranged in between, the arrangement of the connecting interfaces 131, 132 in parallel planes prevents the risk of tilting of the two superimposed panels 2. Furthermore, this connecting structure 13 is thus configured to transfer force between the upper and lower parts of the device 1 of the invention.This transfer of force is essentially carried out, on the one hand, within the framework of a lifting operation of the panel 2, with a tensile force exerted from the attachment interface 11 to a lifting element and, on the other hand, within the framework of the panel 2 installed in the construction, with a compressive force exerted by gravity from the upper part of the device 1 of the invention by construction elements arranged or positioned through or above the connecting structure 13 of the device 1 of the invention.

[0016] According to an example relating to a preferred construction variant of the lifting point device 1 for panel 2 according to the invention, the connecting structure 13 is dimensioned so that, when positioned on the upper surface of panel 2, the lifting point device 1 does not protrude beyond the edges positioned on either side of this upper surface. Furthermore, the device 1 according to the invention avoids creating a raised area relative to the plane of either of the main surfaces of panel 2.

[0017] The connecting structure 13 is also configured to integrate a fastening interface 133 for a means 3 to stop the pouring of a concrete element 31 and / or a receiving interface 134 for an insertion portion of an element 4 to be mounted on the device 1 of the invention. The receiving interface 134 for an insertion portion of an element 4 to be mounted on the device 1 of the invention is implemented in the form of a through opening in a part or surface of the connecting structure 13 or in the form of a housing with an opening to receive at least one additional portion of an element 4 to be mounted on the device 1 of the invention. This element 4 may correspond to a post, a guardrail, a harness for a worker on the construction site, or any other means that may be mounted, attached, or temporarily installed on the upper part of a panel 2.

[0018] According to a conventional configuration, the means 3 for stopping the flow of a concrete element 31 is implemented in the form of a stopping surface arranged in a substantially vertical plane to block the flow of concrete 31 beyond the pouring volume. Preferably, the fastening interface 133 of such a means 3 for stopping the flow corresponds to a surface or the cooperation of several surfaces also arranged in a substantially vertical plane so as to be able to interact easily with a surface of the pouring stop means 3 to position the pouring stop surface of this stop means 3. By way of example, the fixing interface 133 corresponds to a substantially flat surface capable of cooperating with fixing means arranged to be mounted through the fixing interface 133 and the pouring stop means 3 to hold the stop means 3 against the surface of the fixing interface 133. By way of example, the poured concrete element 31 corresponds to a floor slab disposed at the level of the upper part of the panel 2, preferably in a substantially horizontal plane perpendicular to the vertical plane of the panel 2 in position.Furthermore, it should be noted that the fixing interface 133 is preferably configured to face the pouring stop surface of the fixed stopping means 3 so that the connecting structure 13 of the device 1 according to the invention is positioned inside the pouring volume of the concrete element 31.

[0019] According to an example relating to another construction variant of the lifting point device 1 for panel 2 according to the invention, and which can be combined with either of the variants detailed above, in a substantially vertical plane in section, the connecting structure 13 has a substantially perpendicular arrangement between, on the one hand, the fastening interface 133 of at least one stop means 3 disposed in a substantially vertical plane and, on the other hand, the connecting interface 132 with the anchoring interface 12 being disposed in a substantially horizontal plane. According to this construction variant, the connecting structure 13 is able to optimally and precisely position the surface of a stop means 3 relative to the upper surface of the panel 2 on which the device 1 according to the invention is positioned.Thus, due to the arrangement between the fixing interface 133 and the connecting interface 132, which carries the anchoring interface 32 to the panel 2, the connecting structure 13 is able to position the concrete pouring stop means 3, and in particular the pouring stop surface of this stop means 3, in a plane perpendicular to the plane of the upper surface of the panel 2. Furthermore, when the upper surface of the panel 2 is positioned in a plane perpendicular to the plane of either of the two main surfaces of the panel 2, the connecting structure 13 allows the pouring stop surface of the stop means 3 to be positioned in a plane parallel to, or even similar to, if not identical to, the plane of either of the two main surfaces of the panel 2. Thus, after the concrete element 31 has been poured and the stop means 3 removed, the surface of the concrete element 31 is level with the surface of either of the two main surfaces of the panel 2. main surfaces of panel 2. .

[0020] According to an example relating to another construction variant of the lifting point device 1 for panel 2 according to the invention and capable of being combined with either of the variants detailed above, in a substantially In vertical section, the connecting structure 13 has a substantially perpendicular arrangement between, on the one hand, the fixing interface 133 of at least one retaining means 3, disposed in a substantially vertical plane, and, on the other hand, the connecting interface 131 with the hooking interface 11, which is disposed in a substantially horizontal plane. In this embodiment, when the device 1 of the invention is intended to be partially or totally positioned within the pouring volume of the concrete element 31 and thus partially or totally embedded in the concrete element 31, the surface forming the connecting interface 131 to the hooking interface 11 provides a level reference for pouring a screed forming the concrete element 31.Under these conditions, the perpendicular arrangement of the connection interface 131 to the hook interface 11 with respect to the fixing interface 133 of at least one stop means 3 allows the realization of a lateral surface of the concrete element 31 after casting defined by the stop surface of the stop means 3 which is arranged in a plane substantially perpendicular with respect to the plane of the concrete element 31, in particular when the stop surface of the stop means 3 has been mounted in a strictly vertical plane to the fixing interface 133.

[0021] According to an example relating to another construction variant of the lifting point device 1 for panel 2 according to the invention and capable of being combined with either of the variants detailed above, the connecting structure 13 has a construction which includes: - on the one hand, a perimeter closed in a substantially vertical plane in section comprising: - at its upper part, the connection interface 131 to the attachment interface 11, - at its lower part, the linking interface 132 to the anchoring interface 12, - at one of its lateral edges, the fixing interface 133 of at least one casting stop means 3, - on the other hand, an orifice passing through 15 along an axis perpendicular to the vertical plane in section, this orifice passing through 15 being surrounded by the closed perimeter.

[0022] According to this construction variant, the connecting structure 13 thus has an arrangement which, in section in a vertical plane, is closed and traversed by a through orifice 15. This closed arrangement comprises, on the one hand, two connecting interfaces 131, 132 respectively with the attachment interface 11 and the anchoring interface 12 intended to be arranged in substantially horizontal planes to form the upper and lower parts of the closed perimeter of the connecting structure 13 and, on the other hand, at least two portions arranged vertically between the two interfaces connecting elements 131, 132, for example between their respective edges, to close the perimeter of the connecting structure 13. At least one of these two vertical portions is then formed by a fixing interface 133 for a concrete pouring stop means 3. Alternatively or in addition to this fixing interface for a stop means 3, at least one of these two vertical portions is formed by a receiving interface 134 complementary to an insertion portion of an element 4 to be mounted on the device 1. According to one construction example, at least a part of the connecting structure 13 is made in the form of a flat element cut and then folded along parallel folding axes so that two opposite ends of the folded flat element meet, directly or indirectly, so as to close the arrangement of the connecting structure 13 in a vertical plane in section.

[0023] According to an example relating to another construction variant of the lifting point device 1 for panel 2 according to the specific invention of the variant previously detailed, the through orifice 15 is delimited by different portions of the connecting structure 13, namely, above and below, by the two connecting interfaces 131, 132 respectively with the hooking interface 11 and the anchoring interface 12 and, laterally, by at least one portion arranged vertically between the two connecting interfaces 131, 132; this at least one vertical portion being formed, for example, by the fixing interface 133 of a stop means 3.An arrangement of the connecting structure 13 such that the two connecting interfaces 131, 132 are positioned horizontally and joined by at least one portion arranged vertically between these two connecting interfaces 131, 132 allows the through-hole 15 to define a through-hole, at least part of whose cross-section has a rectangular arrangement. Such a rectangular through-hole formed by the opening 15 is thus suitable for receiving an axial element 5 with a cross-section complementary to the opening 15, which can be mounted through the connecting structure 13 of the lifting point device 1 according to the invention. By way of example of implementation, such an axial element 5 corresponds to a beam capable of providing reinforcement, stiffening, or improved resistance to stress of the device 1 of the invention.

[0024] According to an example relating to another construction variant of the lifting point device 1 for panel 2 according to the specific invention of the variant detailed above, the anchoring interface 12 carried by a connecting interface 132 of the connecting structure 13 is configured to include an extension that passes vertically through the connecting structure 13 such that the upper end of this extension of the anchoring interface 12 is fixed or secured to the connecting interface 131 at the hooking interface 11. This extension of the anchoring interface 12 that passes through the connecting structure 13 thus provides additional stiffening of the connecting structure 13. According to a particular construction example, this extension of the anchoring interface 12 realizes one of the two vertical portions which forms a structural junction between the two linking interfaces 131, 132, respectively with the hooking interface 11 and the anchoring interface 12, and closes the perimeter or arrangement of the linking structure 13.

[0025] It should be noted that, according to another construction variant that can be combined with either of the variants detailed above, the lifting point device 1 according to the invention, and more particularly the connecting structure 13, is made of a particularly rigid and resistant metallic material, such as steel, given the stresses it bears. Furthermore, preferably, one or more of the interfaces 131, 132, 133, 134 of the connecting structure 13 includes openings or has an openwork structure so as to limit the weight of the device 1 according to the invention and facilitate its handling by workers on a construction site during the installation of these lifting point devices 1 on different panels 2.

[0026] According to an example relating to another construction variant of the lifting point device 1 for panel 2 according to the invention, and which can be combined with either of the variants detailed above, the receiving interface 134 comprises a hollow cylindrical arrangement with a complementary shape to an insertion portion of an element 4 to be mounted on the device 1. This cylindrical arrangement is thus capable of having a circular, rectangular, triangular, or any other shape cross-section suitable for cooperating with a portion of an element 4 intended to be mounted or installed on the device 1 of the invention. The cylindrical arrangement of the receiving interface 134 thus provides a housing or cavity for the complementary insertion portion of the element 4 to be positioned or installed on the device 1.

[0027] According to an example relating to another construction variant of the lifting point device 1 for panel 2 according to the invention, and which can be combined with either of the variants detailed above, the receiving interface 134 comprises a hollow cylindrical arrangement oriented about a substantially vertical axis. The vertical orientation of the receiving interface 134 thus makes it possible to define an insertion opening 1341 in the cylindrical housing, which is positioned at the upper end of the receiving interface 134. Also, once the insertion portion of the element 4 to be installed on the device 1 is inserted into the hollow cylinder through the opening 1341, this insertion portion remains held in position, by gravity, inside the receiving interface 134.

[0028] According to an example relating to another construction variant of the lifting point device 1 for panel 2 according to the invention and capable of being combined with either of the variants detailed above, the receiving interface 134 provides part of the connecting structure 13 between, on the one hand, a part of the connecting interface 131 to the hooking interface 11 and, on the other hand, a part of the interface of connection 132 to the anchoring interface 12. The receiving interface 134 is then arranged vertically and allows for reinforcement of the rigidity and strength of the connecting structure 13. It should also be noted that, when the connecting structure 13 has, in a vertical plane in section, a closed arrangement and is traversed by a through orifice 15, the receiving interface 134 is then capable of forming one of the two vertical portions to create a structural junction between the two connecting interfaces 131, 132, respectively with the attachment interface 11 and the anchoring interface 12, and close the perimeter or arrangement of the connecting structure 13. Such a construction is particularly likely to be achieved when the receiving interface 134 comprises a cylindrical arrangement arranged along a substantially vertical axis.

[0029] According to an example relating to another construction variant of the lifting point device 1 for panel 2 according to the invention and capable of being combined with either of the variants detailed above, the hollow cylindrical arrangement of the receiving interface 134 includes an opening 1341 positioned at the upper surface of the connecting interface 131 to the hooking interface 11. According to this construction variant, the cylindrical arrangement is made through the part of the connecting structure 13 that forms the connecting interface 131 to the hooking interface 11 to allow the positioning of its opening 1341 at the connecting interface 131.

[0030] The invention also relates to an assembly characterized in that this assembly comprises: - a panel 2 arranged in a substantially vertical plane, - at least one lifting point device 1 according to the invention, the interface of which anchorage 12 cooperates with a portion of the upper part of the panel 2.

[0031] According to an example relating to a construction variant of the assembly according to the invention, the assembly comprises at least two lifting point devices 1 according to the invention whose anchorage interfaces 12 cooperate with respective portions of the upper part of the panel 2. According to this construction variant, the at least two devices 1 according to the invention are preferably arranged in similar orientations with respect to the panel 2, that is to say, such that the different interfaces 131, 132, 133, 134 of the connecting structure 13 of each of the devices 1 are oriented similarly with respect to the different surfaces of the panel 2.

[0032] According to an example relating to another construction variant of the assembly according to the invention and capable of being combined with either of the variants detailed above, the anchoring interface 12 of at least one lifting point device 1 cooperates with at least one vertical post 21 of the panel 2. Such an The storage thus allows for the transfer of effort from device 1 of the invention to panel 2 through an element of panel 2 structurally arranged along the height of panel 2. The transfer of tensile or compressive forces at the level of a single structural part thus makes it possible to limit, if not avoid, weaknesses that may exist, in particular at the junctions between several elements fixed together.

[0033] According to an example relating to another construction variant of the assembly according to the invention and capable of being combined with either of the variants detailed above, the assembly also includes a pouring stop means 3 mounted on the fastening interface 133 of at least one lifting point device 1. When the assembly includes several lifting point devices 1 placed side by side along the upper part of a panel 2, a pouring stop means 3 is preferably mounted to cooperate with the respective fastening interfaces 133 of several side-by-side devices 1. Such an arrangement thus allows the stop means 3 to be anchored to the panel 2 by the side-by-side devices 1 so that at least a portion of the forces borne by the stop means 3 under the pressure of the concrete during pouring are transmitted to the panel 2.Through the juxtaposed devices 1, the stopping means thus benefits from the rigidity and resistance of the panel 2 to support the pressure forces imposed by the pouring of the concrete element 31. .

[0034] According to an example relating to another construction variant of the assembly according to the invention and capable of being combined with either of the variants previously detailed, the assembly also includes a concrete element 31 cast at the level of the upper surface of the panel 2, the thickness of this concrete element 31 having, at the level of the upper surface of the panel 2, a thickness substantially identical to the height of the connecting structure 13 of at least one lifting point device 1.

[0035] According to an example relating to another variant of the construction of the assembly according to the invention and capable of being combined with one or the other of the variants previously detailed, the assembly also includes at least one element 4 mounted on at least one lifting point device 1 and of which an insertion portion is complementary to a receiving interface 134 carried by at least one device 1.

[0036] According to an example relating to another construction variant of the assembly according to the invention and capable of being combined with either of the variants detailed above, the assembly also comprises at least one axial element 5, such as a beam, mounted through the through-hole 15 of at least one lifting point device 1. When the assembly comprises several lifting point devices 1 juxtaposed along the upper part of a panel 2, the axial element 5 is preferably mounted to cooperate with the aligned through-holes 15. respective of several juxtaposed devices 1. Such an arrangement thus allows the axial element 5 to be anchored to the panel 2 by the juxtaposed devices 1 but also provides stiffening and / or improved resistance of the devices 1 to the forces which pass through the connecting structures 13 of the different juxtaposed devices 1.

[0037] Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications remain possible, particularly with regard to the composition of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
