Description

Title of the invention: Building and associated lifting system

[0001] The present invention relates to the field of building, and relates more particularly to a building comprising a wooden frame and at least one pair of lifting stirrups as well as to an associated lifting system.

[0002] The desire for mobility, constraints linked to urban planning, manufacturing issues, and controlling the ecological footprint are all reasons that contribute to the search for reversible or mobile housing projects such as tiny houses, mobile homes, or chalets.

[0003] Some of the buyers of these constructions seek to combine several characteristics such as a reduced footprint, low ground clearance for possible transport, the presence of an interior mezzanine to increase the living space with the same footprint, reversibility due to the absence of heavy foundations, sobriety of construction (particularly ecological), little maintenance, reduced cost.

[0004] For reasons of working conditions, quality of construction and ease, it is interesting to be able to carry out these constructions in the workshop, then to deliver the building (or not) to its installation site.

[0005] Existing buildings have disadvantages:

[0006] - for tiny houses on trailers: the cost of the trailer is high, the mass construction is limited by what the trailer can move, the dimensions are limited to those of the road gauge, the legislative framework is poorly defined, the height of the trailer implies a loss of habitable height in the building with constant ground clearance, steel is used massively;

[0007] - for mobile home type chassis: chassis with small wheels underneath, traditionally used for mobile homes, do not have a large rolling capacity, also encroach on the construction height and require specific handling means;

[0008] - for constructions without a particular base, chalet type: they do not do not allow easy recovery and require the use of specific lifting elements (cross bars, spreaders).

[0009] The existing buildings therefore do not meet the requirements of purchasers indicated above.

[0010] US patent US6481165B1 describes a building transport device comprising brackets positioned at the upper and lower ends of the walls and connected by a rod passing through the frame of the building. However, such a device is particularly complex to assemble and weakens the frame of the building due to the drilling required for the rod, without prejudice to the tensile forces at floor level.

[0011] Japanese patent JP95076492B2 describes a building moving device comprising elements sandwiching the lower end of the pillar of a building to be moved, and secured by bolts arranged on either side of the pillar. However, such a device requires the use of beams placed under the elements and on which the hoisting points are offset. Such a device is thus complex to implement and leads to a greater footprint of the structure on the ground and an increase in the ground clearance of the building equipped with its device, whether on the site of construction or installation of the building or on a vehicle for transporting it, as well as an increased weight.

[0012] There is therefore a need for a movable building equipped with a lifting system which is compact, rigid and robust, as well as easy to install and implement.

[0013] The Applicant therefore proposes to meet these needs by using a building equipped with at least one pair of lifting stirrups, the lifting stirrups being U-shaped and sandwiching the lower end of the beams forming the belt of the building, two stirrups of the same pair mounted on opposite walls of the building being connected by a rod.

[0014] The present invention therefore relates to a building comprising a wooden frame with walls and a floor, having four beams at the lower end of the walls and forming the belt of the building supporting the floor of the building, the beams having a lower end, the building further comprising at least one pair of U-shaped lifting stirrups, each stirrup being configured to encase the lower end of the beams, the two arms of the U sandwiching the lower end of the beams and the base of the U supporting the lower end of the beams, and the building further comprising a rod connecting two stirrups of each pair of lifting stirrups, mounted on two opposite walls, and passing through the two arms of the U of each stirrup as well as the lower end of the beam sandwiched by the stirrups.

[0015] The present invention is therefore a device to be installed on the periphery of the load-bearing floor of a building and which makes it possible to have standardized and identified attachment points for handling the building and thus allowing it to be moved in good economic and safety conditions, while allowing the construction to meet the criteria sought by the purchaser indicated above.

[0016] Thus, the stirrups are arranged in the outer part of the floor of the house / tiny house and accessible from the outside of it without, however, exceeding the width of the construction.

[0017] In the case where the floor of the building is supported by joists, the building belt may consist of beams either of substantially the same thickness as the floor joists, or thicker. In the first case, the arm of the stirrup on the inside (towards the inside of the building) may be made to protrude slightly into the insulation of the building floor. Thus, for example, for a 145 mm floor, and belt beams of substantially the same thickness, the arm of the U on the inside will be partially embedded in the floor.

[0018] Preferably, at least four stirrups (two pairs with their corresponding rod) may be arranged around the floor of the building to enable the structure to be lifted in a stable manner. Preferably, the pairs of stirrups are arranged such that their corresponding rods are parallel. The invention is however not limited in this respect and the rods of two pairs of stirrups may also be orthogonal to each other.

[0019] The stirrups are connected in pairs. In one embodiment, a drawbar / link / threaded rod connects the arms of the U to take up the tensile forces that are induced by a lifting phase.

[0020] According to one embodiment, each stirrup is also equipped with screws passing through the two arms of the U and assembling them by nuts, the screws being configured to pass through a hole made in the beam sandwiched by the stirrup.

[0021] Thus, the through screws come to sandwich the associated beam between the outer and inner plates.

[0022] According to one embodiment, the arms of the U are constituted by two vertical and parallel plates, connected by a horizontal lower plate perpendicular to the other two plates, the two vertical plates sandwiching the lower end of the corresponding beam and the lower plate supporting the lower end of the corresponding beam, and the rod passing through the two vertical plates of each stirrup.

[0023] Thus, each interface is composed of a set of three plates which are assembled around the edge of the beam, which can, for example but not exclusively, be made of Kerto® (or other structural wood).

[0024] The elements are steel plates which have elements for the installation of handling / lifting / lashing equipment.

[0025] Furthermore, the lower plate is, by construction, trapped by the other two.

[0026] According to one embodiment, the two vertical plates have holes and the lower plate has projections configured to fit into the holes in the vertical plates.

[0027] Thus, the elements are assembled without welding.

[0028] According to one embodiment, the stirrups comprise at least one ring, preferably arranged at the level of the vertical plate intended to be arranged on the interior side of the building, designated internal vertical plate.

[0029] According to one embodiment, the at least one ring is constituted by a projection formed on the lower plate.

[0030] Thus, the ring in the inner part allows for securing during the transport phases by connection to the trailer, during the construction of the building, stability on the installation site, to avoid movements of the building (vibration, wind, etc.).

[0031] According to one embodiment, the vertical plate intended to be arranged on the exterior side of the building, designated the external vertical plate, comprises a thread for fixing a shackle.

[0032] Thus, the tapping is dedicated to the screwing of a shackle for lifting.

[0033] Several threads can allow the addition of equipment, in particular jacks / crutches for lifting (manual, electric, hydraulic, etc.).

[0034] According to one embodiment, the building comprises a lifting support, configured to be acted upon by a crutch, the lifting support comprising a fixing plate for fixing to a stirrup and a lifting plate for fixing to the crutch, connected by lateral recovery consoles.

[0035] According to one embodiment, the fixing plate is fixed to the external vertical plate of the stirrup by screws received in threads made in the external vertical plate and bores made in the fixing plate.

[0036] According to one embodiment, the lateral recovery consoles comprise arms extending beyond the fixing plate and configured to support the external vertical plate, the arms further comprising returns configured to return under the external vertical plate or even under the lower plate.

[0037] According to one embodiment, the fixing plate comprises an opening for the passage of at least one of the rod alone or the rod and screws.

[0038] According to one embodiment, the fixing plate comprises a thread for fixing a shackle.

[0039] According to one embodiment, the rod is made up of several elements assembled together, for example the elements can be several 1m threaded rods screwed together by long nuts, which allows the lifting system to be palletized.

[0040] The present invention also relates to a lifting system comprising at least one assembly comprising a pair of lifting stirrups comprising two parallel vertical plates connected by a perpendicular horizontal lower plate, and a rod configured to connect the two stirrups of the pair and pass through the two vertical plates of each stirrup for use in a building as mentioned above.

[0041] The present invention is therefore a device to be installed on the periphery of the load-bearing floor of a building and which makes it possible to have standardized and identified attachment points for handling the building and thus allowing it to be moved in good economic and safety conditions while allowing the construction to meet the criteria sought by the purchaser indicated above.

[0042] Thus, the stirrups are arranged in the outer part of the floor of the building / tiny house and accessible from the outside of it without, however, exceeding the width of the construction.

[0043] The elements are steel plates which have elements for the installation of handling / lifting / lashing equipment.

[0044] Furthermore, the lower plate is, by construction, trapped by the other two.

[0045] According to one embodiment, each stirrup is also equipped with screws passing through the two vertical plates assembling them with nuts.

[0046] Thus, the bolts consisting of the through screws and the corresponding nuts sandwich the building between the outer and inner plates.

[0047] According to one embodiment, the two vertical plates have holes and the lower plate has projections configured to fit into the holes of the vertical plates.

[0048] Thus, the elements are assembled without welding.

[0049] According to one embodiment, the stirrups comprise at least one ring, preferably arranged at the level of the vertical plate intended to be arranged on the interior side of the building, designated internal vertical plate.

[0050] Thus, the ring in the inner part allows for securing during the transport phases by connection to the trailer, during the construction of the house, stability on the installation site, to avoid movements of the house (vibration, wind, etc.).

[0051] According to one embodiment, the at least one ring is constituted by a projection formed on the lower plate.

[0052] According to one embodiment, the vertical plate intended to be arranged on the exterior side of the building, designated external vertical plate, comprises a thread for fixing a shackle.

[0053] Thus, the tapping is dedicated to the screwing of a shackle for lifting, several tappings allowing the addition of equipment, in particular jacks / crutches for lifting (manual, electric, hydraulic, etc.).

[0054] According to one embodiment, the lifting system comprises a lifting support, configured to be acted upon by a stand, the lifting support comprising a fixing plate for fixing to a stirrup and a lifting plate for fixing to the stand, connected by lateral recovery consoles.

[0055] According to one embodiment, the fixing plate is fixed to the external vertical plate of the stirrup by screws received in threads made in the external vertical plate and bores made in the fixing plate.

[0056] According to one embodiment, the lateral recovery consoles comprise arms extending beyond the fixing plate and configured to support the external vertical plate, the arms further comprising returns configured to rise behind the external vertical plate.

[0057] According to one embodiment, the fixing plate comprises an opening for the passage of at least one of the rod alone or the rod and screws.

[0058] According to one embodiment, the fixing plate comprises a thread for fixing a shackle.

[0059] According to one embodiment, the rod is made up of several elements assembled together, for example the elements can be several 1m threaded rods screwed together by long nuts, which allows the lifting system to be palletized.

[0060] To better illustrate the object of the present invention, several embodiments will be described below, for informational and non-limiting purposes, with reference to the attached drawings.

[0061] In these drawings:

[0062] [Fig. 1] is a perspective view from a first angle of a lifting bracket of a lifting system according to the present invention;

[0063] [Fig.2] is a perspective and exploded view of the lifting system of [Fig.l];

[0064] [Fig.3] is a perspective view from a second angle of the lifting bracket of the [Fig.l];

[0065] [Fig.4] is a perspective view from a first angle of a lifting bracket of a lifting system according to a variant;

[0066] [Fig.5] is a side view of the lifting bracket of Figures 1-3;

[0067] [Fig.6] is a perspective view of a building equipped with a lifting system according to the present invention;

[0068] [Fig.7] is a perspective view of a lifting support equipped with the system of lifting according to the present invention fixed on a crutch;

[0069] [Fig.8] is a perspective view of a building beam equipped with a system of lifting and a lifting support according to the present invention.

[0070] Referring to [Fig.6], it can be seen that there is shown a building in the form of a house 1 comprising a wooden frame 2 with walls 3 and a floor 4, having four beams 5 at the lower end of the walls 3, forming the belt of the house 1 and supporting the joists of the floor of the house when the floor 4 is made of joists.

[0071] The house 1 is equipped with a lifting system 6 according to the present invention. The lifting system 6 comprises two pairs of lifting stirrups 7 (only one of which is shown in Figures 1-5 and 7-8) and a rod 8 connecting the two stirrups 7 of the pair.

[0072] As can be seen in Figures 1-5, the stirrups 7 are U-shaped and comprise two vertical and parallel plates 9, 10, connected by a perpendicular lower plate 11, the vertical plates 9, 10, forming the arms of the U and the lower plate 11 forming the base of the U.

[0073] As can be seen in Figures 3, 5, 6 and 8, the stirrups 7 are configured to encase the lower end 12 of the beams 5, the two vertical plates 9, 10 sandwiching the lower end 12 (lower edge) of the beams 5, and the lower plate 11 supporting the lower end 12 of the beams 5.

[0074] The stirrup 7 thus has a vertical plate 9 intended to be arranged on the inside of the house 1, designated the internal vertical plate, and a vertical plate 10 intended to be arranged on the outside of the house 1, designated the external vertical plate.

[0075] In Figures 1-4, it can be seen that the two vertical plates 9, 10 of each stirrup 7 have holes 13, 14 at their lower longitudinal edge 15, 16 and that the lower plate 11 has projections 17, 18 along its two longitudinal edges 19, 20.

[0076] The projections 17, 18 are configured to fit into the holes 13, 14 of the vertical plates 9, 10.

[0077] It should be noted that the person skilled in the art will be able to envisage the number, shape and distribution of the holes and projections insofar as they allow the lower plate 11 to fit together with the two vertical plates 9, 10 to form a U-shaped stirrup 7.

[0078] According to the embodiment shown in Figures 1-2 and 4, it can be seen that the holes 14 of the external vertical plate 10 are T-shaped, extending from the lower longitudinal edge 16 of the external vertical plate 10. The corresponding projections 18 of the lower plate 11 are also T-shaped. Thus the interlocking of the lower plate 11 with the external vertical plate 10 is achieved by passing the head 21 of the T-shaped projection 18 of the lower plate 11 into the head 22 of the T-shaped hole 14 of the external vertical plate 10 and abutting the head 21 of the T-shaped projection 18 of the lower plate 11 against the base of the T-shaped hole 14 of the external vertical plate 10.

[0079] Additional means of fixing can be envisaged, such as welding for example.

[0080] Thus, once the stirrup 7 is assembled by assembling the vertical plates 9, 10 and the lower plate 11, on the one hand the projections 18 of the lower plate 11 are wedged in the holes 14 of the external vertical plate 14, but in addition, once the plates verticals 9, 10 fixed to the beam 5 by the screws, the weight of the beam 5 on the lower plate 11 ensures the cohesion of the entire stirrup 7.

[0081] The advantages of such an assembly of the stirrup from three plates are multiple, in particular ease of assembly, the absence of welding tools and therefore reduced assembly time using conventional tools, ease of assembly and the possibility of disassembly allowing reuse of the stirrups on other buildings, if the building on which they are mounted does not / no longer need to be moved once placed in a specific location.

[0082] Also, this ease of assembly allows installation directly in the manufacturer's workshop, without necessarily requiring additional specialized personnel, as could be the case in the state of the art.

[0083] In [Fig. 2], it can be seen that the holes 13 of the internal vertical plate 9 are rectangular in shape. The corresponding projections 17 of the lower plate 11 are in the form of rings opening out to the outside of the stirrup 7, beyond the internal vertical plate 9.

[0084] The ring-shaped projections 17 are configured to allow the house 1 to be secured by means of the stirrup 7, in particular during transport on the platform P of a truck C, or even at the place of installation of the house 1 (see [Fig.6]).

[0085] It should be noted that the holes / protrusions may be of the same type on the inner vertical plate side and the outer vertical plate side, the rings then being separate elements. The projections 17 of the plate 11 are not limited by the present invention to the shape of rings, and other shapes are also envisaged for the projections 17, without the invention being limited in this respect.

[0086] As can be seen in Figures 1-4, the vertical plates 9, 10 comprise a primary bore 23 facing one plate 9, 10 to the other, and configured for the passage of the rod 8, the rod 8 opening beyond the external vertical plate 10 and being secured to two stirrups 7 of a pair, mounted on opposite walls 3, by means of nuts 24.

[0087] A hole is made in the beam 5 to allow the passage of the rod 8 as can be seen in [Fig.5].

[0088] The rod 8 is configured to allow the absorption of the tensile forces endured by the house 1 when it is lifted, the floor 4 (possibly its joists if joists are necessary for the floor of the building in question) supporting the compressive forces.

[0089] The rod 8 may be of the threaded type. Advantageously, the rod may be composed of several screwed elements, for example several 1 m threaded rods screwed together by long nuts. The person skilled in the art will be able to envisage the type of rod and its method of securing to the stirrups provided that it passes through the stirrups and the beams and allows the tensile forces to be taken up.

[0090] Furthermore, the vertical plates 9, 10 comprise secondary bores 25 facing one plate 9, 10 to the other and the stirrups 7 are equipped with screws 26 passing through said secondary bores 25 and secured to the vertical plates 9, 10 by nuts 27.

[0091] Holes are made in the beam 5 to allow the passage of the screws 26 in order to sandwich the beam 5 as can be seen in [Fig.5].

[0092] The external vertical plate 10 also includes a thread 28 for fixing a shackle 29. The shackle 29 is configured to hook there, for example, a chain 30 to lift the house 1, as can be seen in [Fig.6].

[0093] According to a variant shown in [Fig.4], the external vertical plate 10 is devoid of threading for fixing a shackle.

[0094] The external vertical plate 10 comprises tertiary threads 31, the role of which will be explained below.

[0095] Advantageously, the external vertical plate 10 has a length greater than the internal vertical plate 9, from the lower plate 11. The external vertical plate 10 has bores 43 for the passage of lag screws 44 which fix the external vertical plate 10 to the beam 5.

[0096] Furthermore, as can be seen in [Fig.3], the lower plate 11 is provided with holes 32 for the passage of screws, for example for fixing to the beam 5.

[0097] According to the embodiment shown in [Fig.8], it can be seen that the house 1 comprises a lifting support 33, configured to be acted upon by a crutch B. The crutch can be of the electric, mechanical type as can be seen in Figures 7-8, hydraulic or pneumatic.

[0098] The lifting support 33 comprises a fixing plate 34 for fixing to the external vertical plate 10 of a stirrup 7 and a lifting plate 35 for fixing to the stand B. The fixing plate 34 and the lifting plate 35 are parallel and connected by two lateral recovery consoles 36, perpendicular to them.

[0099] The fixing plate 34 is fixed to the external vertical plate 10 of the stirrup 7 by screws 37 received in the tertiary threads 31 made in the external vertical plate 10 and corresponding bores 38 made in the fixing plate 34.

[0100] The lateral recovery consoles 36 comprise arms 39 extending beyond the fixing plate 34 and configured to support the external vertical plate 10, the arms 39 have their free end 40 in the form of returns configured to rise behind the external vertical plate 10 and serve as an anti-rotation to take up the traction which is exerted in the bottom of the assembly when the house 1 is supported on crutches.

[0101] The fixing plate 34 also has an opening 41 to allow the passage of the rod 8 and its nut 24 opening beyond the external vertical plate 10, as can be seen in [Fig.5], as well as the two central screws 26.

[0102] Advantageously and as shown in [Fig.7], the fixing plate 34 has a thread 42, positioned to correspond with the thread 28 of the external vertical plate 10 for the passage of the shackle 29, or a bore in the absence of a thread.

[0103] For example, for a micro house with a wooden frame, the floor consists of a 150 mm high joist surrounded by 200 mm wood forming a belt. The plates are positioned outside the belt of this floor. During a lifting phase, the compressive forces will be taken up by the frame while the tensile forces will pass through the connecting bars / threaded rods. As an illustrative example not intended to limit the scope of the invention, the plates can be made of S355 steel and then undergo a zinc-plated treatment, the shackle interface can be an M24 thread, the equipment interfaces can be M16 threads, the connections between the plates to sandwich the frame can be of the M12 thread type.

[0104] Preferably, there are at least two pairs of stirrups mounted in parallel.

[0105] It is however understood that there may be more pairs of stirrups, and that the pairs of stirrups can be mounted parallel and / or orthogonal to each other.

[0106] The advantages of the present invention, in particular with respect to the aforementioned Japanese patent JP95076492B2, are the fact of having stirrups which minimize the use of steel, the junction of the pairs of stirrups by the rod taking up the traction, the capacity to receive a lifting shackle,

[0107] the capacity to receive jacks / crutches and additional elements. The stirrup-forming parts are made of sheets that are only cut and tapped and are assembled using a system of assembly keys, without welding. The external plates are equipped with interfaces for lifting (by direct screwing of a shackle or by adding a jack / crutch) which allows for hoisting points to be directly accessible in the external part of the building. The proposed design allows a building to be placed without any particular ground clearance (only the overhang of the plates at the bottom of the beams of the building, for example approximately 2 cm).In the case of transport on a truck trailer where the overall height is to be reduced for the passage of engineering structures (low ground clearance), the present invention does not involve raising the building, adapts to the floor of any timber-framed building by fixing to the beams forming the belt of said floor and without limit or consideration of the method of fixing the building to its foundations (slab, piles, stilts, laying on the ground, etc.). In addition, the stirrups have the anchoring system to the . means of transport (the rings), and are connected by the rod, which allows secure securing of the building during transport.

[0108] According to the present invention, when lifting, the traction induced in the lower part is taken up by the threaded rod and the compression induced in the upper part is taken up by the wooden beams of the frame. The entire technology is minimalist and light, economical in material, potentially reusable, which responds to an eco-responsible and weight monitoring problem.

[0109] It is understood that the embodiments which have just been described have been given for informational and non-limiting purposes and that embodiments may be made thereto without departing from the scope of the present invention.
