Description

TECHNICAL FIELD

[0001] The present invention relates to a device for moving and leveling a prefabricated room module.

[0002] The device, integrated into the module, allows the efficient transportation of room modules, e.g. living rooms, bedrooms, bathrooms, prefabricated for installation, while ensuring the proper leveling for different types of floors, in the desired locations.BACKGROUND

[0003] The positioning of modular units, such as prefabricated room modules, inside buildings is a common challenge in construction projects using this type of construction. Currently, their installation inside a building involves several stages, transportation, installation / placement, leveling and connection to public services, e.g. water and electricity.

[0004] Since the modules are quite heavy and large, rushed transportation and respective placement can damage the module or injure the workers handling the same.

[0005] For transportation, it is usually necessary to place handling tools underneath the module. There are two most common solutions for handling: the use of pallet trucks combined with hydraulic jacks and the use of wheeled lifting equipment.

[0006] Pallet trucks combined with hydraulic jacks have several limitations, including: limitations associated with the dimensions of the modules being transported - pallet truck forks are typically limited to a maximum of 2m, and since the pallet truck is positioned underneath the module, the ratio between the height of the module and the free height between the floor slabs of the building is more restricted, at least + / -22 cm difference. Since the positions on the module for placing the pallet truck are not usually fixed, its positioning is done randomly and according to the operator's judgement, which introduces risks to the integrity of the module materials and safety during handling.

[0007] This solution does not cover eliminating the risk associated with the road transport of the prefabricated modules. For handling the modules, their placement is done during the lifting and placement of the modular unit onto the unloading platform. A prefabricated one-room module is, for example, a student residence room with a sleeping area. In the particular case of a prefabricated module with installed services and integrated finishes, it is called a POD. These PODs usually have a smaller volume corresponding to single-use spaces, e.g. a bathroom or kitchen.

[0008] When the POD is in elevation with the crane, the accuracy of placement is significantly lower, depending on the ability of the crane operator and the operator trying to place the pallet truck under the module. The possibility of misalignments is real, with an increased risk of load imbalance during movement. In addition, the use of supplementary equipment, e.g. hydraulic jacks, is still required for the operation of removal of the pallet trucks.

[0009] For larger geometries / volumes, the use of more than one pallet truck is possible, but it creates constraints on the maneuverability of the module on site.

[0010] Alternatively, wheeled lifting equipment can be used, which is more versatile in terms of the dimensions and volumes of the modules being moved. However, these have the following limitations: depending on the fixing points chosen (which can be fixed to the base or to the wall uprights), additional stresses may be applied at these support points, which, if not taken into account by the product manufacturer, can compromise the integrity of the module's finishes; since the positions on the module for placing this equipment are not usually fixed, its positioning is done randomly and according to the operator's judgement, which introduces risks to the integrity of the module materials and safety during handling; also in general wheeled lifting equipment is more expensive to implement than pallet trucks. Usually, this is a more technically complex solution and more costly in terms of the time needed to carry out the handling operations.

[0011] The operation of lifting and placing the modular products on the unloading platforms entails inefficiencies associated with the difficulty of positioning the modules on the handling equipment inside the building, introducing a risk of damage to the product, resulting from non-uniform support of the modules, as there is no standard methodology that is the same for all modules, depending largely on the skill of the workers.

[0012] For leveling, it is necessary to ensure that the module is perfectly leveled and stable on the floor, namely by inspecting the floor to detect any unevenness or irregularities. This is usually checked by placing a spirit level on the floor of the room's module to verify leveling or by using a laser level for greater precision.

[0013] If the floor is not leveled, it may be necessary to solve this problem first. Depending on the severity of the unevenness, a self-leveling compound can be used, wedges to level the floor, or adjust the leveling feet of the prefabricated modules. These feet can be raised or lowered to level the module. However, they do not allow the module to be moved, i.e. it must already be in its final position. They are also limited in terms of the compensation they can provide for unevenness, and may not be enough to neutralize the unevenness on an irregular floor.

[0014] In addition, the quality guarantee associated with the correct leveling of the product, ensuring that there are no twists that could compromise the operation in use and the compatibility with the building's infrastructure and finishing layers, is another of the critical factors associated with the use of these prefabricated room modules in construction.

[0015] These facts are described in order to illustrate the technical problem solved by the embodiments of the present document.GENERAL DESCRIPTION

[0016] The present invention relates to a device for moving and leveling prefabricated room modules. The device enables the efficient transportation of prefabricated room modules to the desired locations, while ensuring the correct leveling on different types of floors.

[0017] This solution aims to streamline the process of installing prefabricated room modules, offering greater convenience and precision in the construction industry, minimizes on-site construction time and reduces costs, making it an attractive choice for several construction projects. Overcoming the geometric constraints associated with the size of the modules and the configuration of the building / floor itself, which limit the possibilities for lifting and moving these products to their final position.

[0018] An aspect of the present disclosure relates to a horizontal base for supporting, moving and leveling a prefabricated room module comprising three or more lateral profiles for forming lateral faces of said base; and device for moving and leveling said base, comprising: a surface for supporting against an external moving element, two fastening connectors, i.e. axial, with internal thread configured for receiving horizontal screws for fixing the external moving element to said device, and a leveling connector, i.e. transverse, with internal thread, to receive a vertical threaded rod, wherein the vertical threaded rod is configured for vertically displacing the device relative to a support surface.

[0019] In an embodiment, the three or more lateral profiles are configured as a formwork for a base slab for supporting, moving and leveling a prefabricated room module.

[0020] In an embodiment, the base comprises said base slab and said three or more lateral profiles as a lost formwork.

[0021] In an embodiment, the device is integrally formed in at least one of the three or more lateral profiles.

[0022] In an embodiment, the base device comprises two horizontal rods arranged inside said slab, wherein each of said two horizontal rods is connected at one end to one of the two fastening connectors with internal thread.

[0023] In an embodiment, the two horizontal rods are externally threaded.

[0024] An aspect of the present disclosure relates to a horizontal base for supporting, moving and leveling a prefabricated room module comprising: a base slab, comprising at least two surfaces for supporting against an external moving element; two horizontal rods arranged inside said slab; two fastening connectors with internal thread configured for receiving horizontal screws for fixing the external moving element to said device, and configured for receiving the two horizontal rods, wherein each of said two horizontal rods is connected at one end to one of the two fastening connectors with internal thread; and a leveling connector, i.e. transverse, with internal thread, to receive a vertical threaded rod, wherein the vertical threaded rod is configured for vertically displacing the device relative to a support surface.

[0025] In an embodiment, the two rods are connected to another device at another end, wherein said other device comprises: a surface for supporting against an external moving element, two fastening connectors, i.e. axial, with internal thread configured for receiving horizontal screws for fixing the external moving element to said device, a leveling connector, i.e. transverse, with internal thread, to receive a vertical threaded rod, wherein the vertical threaded rod is configured for vertically displacing the device relative to a support surface.

[0026] In an embodiment, the three or more lateral profiles have a cross-section with the shape of an L angle, a rectangular or square tubular shape, U-shaped, T-shaped or I-shaped.

[0027] In an embodiment, the external moving element comprises at least one wheel, preferably the at least one wheel being a free wheel.

[0028] In an embodiment, at least two of the three or more lateral profiles comprise a connection component for receiving lashing belts.

[0029] In an embodiment, the slab is made of concrete, wood, metal, or combinations thereof.

[0030] An aspect of the present disclosure relates to a method of installing the base for supporting, moving and leveling a prefabricated room module comprising the steps of: placing the prefabricated room module on a top of the respective base described above; connecting the external moving element to the two fastening connectors, i.e. axial, with internal thread; moving the respective base with the prefabricated room module to a predefined installation position; screwing a vertical threaded rod, such as a threaded shaft, into a leveling connector, i.e. transverse, with internal thread to vertically displace the respective base with the prefabricated room module.

[0031] In an embodiment, the connections of the external moving element to the two fastening connectors with internal thread is made using horizontal screws.

[0032] In an embodiment, the method of installing the base further comprises the step of removing the external moving element.

[0033] In an embodiment, the method of installing the base further comprises the step of unscrewing the vertical threaded rod from the leveling connector, i.e. transverse, with internal thread to vertically displace the base with the prefabricated room module from a raised position to a lowered position. In the lowered position, the base and the module are arranged on the support surface.

[0034] The variability of the volume and weight of the prefabricated modules leads to the need for a product that can be scaled to different dimensions and weights. With the development of this solution, the response to a given level of demand is customized, integrating a greater or lesser number of devices into the prefabricated module depending on its characteristics and ensuring applicability to multiple configurations.

[0035] In one aspect of the present disclosure, the solution includes within the prefabricated module a mechanism capable of connecting several accessories, particularly for moving, and capable of carrying out the respective movements necessary to ensure the correct altimetric positioning.

[0036] In an embodiment, it allows the moving devices to be incorporated while the module is still supported on the truck.

[0037] The characteristics of the buildings, in particular the useful height between floor slabs, affect the maximum height that modular products can acquire. The need to place the module on an equipment (pallet truck, load lift, etc.) increases the limitations associated with the height of the prefabricated module. To minimize this constraint, the present disclosure incorporates the moving systems laterally rather than under the module, significantly reducing the spacing required between the base of the module and the floor level (height above ground).

[0038] Removing the moving accessories typically requires the use of a supplementary accessory for this purpose, e.g. a hydraulic jack. With the present disclosure, the device used to lift the module and which allows the wheels to be removed is incorporated into the module, ensuring that the support points provided for in the design are used for this purpose, and eliminating the need to use multiple supplementary equipment.

[0039] In an embodiment, the altimetric adjustment is carried out by means of the system incorporated in the module, since it incorporates the mechanism for placing the product's altimetric adjustment shaft.

[0040] An aspect of the present disclosure relates to a base for moving and leveling a prefabricated room module comprising: a slab configured for supporting a prefabricated room module; at least two pairs of axial connectors arranged on opposite sides of said slab; at least one transverse connector arranged between a pair of axial connectors spanning the entire thickness of the slab of the prefabricated room module; at least three threaded rods; wherein the pairs of axial connectors are configured for receiving means of movement externally; wherein two threaded rods are axially fixed within the slab of the prefabricated room module to a pair of axial connectors, and the third threaded rod is connected to the transverse connector for leveling the prefabricated room module.

[0041] In an embodiment, the base described in the present disclosure may further comprise at least one profile arranged on the perimeter of the slab of the prefabricated room module to support at least one pair of axial connectors and / or at least one transverse connector.

[0042] In an embodiment, the profile has an L-, U-, T-, I- or I-shaped cross-section.

[0043] In an embodiment, the slab is made of concrete, wood, metal (with any cross-section), or a combination thereof, i.e. mixed.

[0053] The present disclosure relates to a device for moving and leveling a prefabricated room module, preferably a device for moving prefabricated bathrooms, kitchens, bedrooms, or living rooms.

[0054] Figures 1A-1D show a schematic representation of two embodiments of a base for moving and leveling a prefabricated room module in perspective view with and without a slab, where 001 represents a horizontal rod, 002 represents a fastening connector with internal thread, preferably a horizontal nut, 101 represents a vertical threaded rod or a shaft, 103 represents a leveling connector with internal thread, preferably a thread, 105 represents a slab, and 109 represents a lateral profile, more specifically one side of the base structure.

[0055] In an embodiment, the device is applied to the structural elements that make up the base of the prefabricated modules, which can be incorporated into concrete, metal (with any cross-section) or mixed bases. A set of connecting nuts, rods and / or bolts are added to these bases, arranged in the thickness of the base elements of the module, providing the necessary mechanism for the connection of accessories that allow to increase the efficiency and safety of the aforementioned operations.

[0056] In an embodiment, the modules have non-parallel sides, e.g. in the shape of a pentagon or triangle.

[0057] Figure 2 shows a schematic representation of an embodiment of a base for moving and leveling a prefabricated room module on a concrete slab with profile, where 001 represents a horizontal rod, 002 represents a fastening connector, i.e. axial, with internal thread, 003 represents a leveling connector, i.e. transverse, with internal thread, 004 a lateral profile, and 201 represents a slab.

[0058] In an embodiment, the rod is fully or partially threaded so that it can be screwed to the connecting nut, 002. Alternatively, the rod is smooth and welded to the nut, 002.

[0059] Figure 3 shows a schematic representation of an embodiment of a base for moving and leveling a prefabricated room module on a concrete slab without profile, where 001 represents a horizontal rod, preferably a horizontal threaded rod, 002 represents a fastening connector with internal thread, preferably a horizontal nut, 003 represents a leveling connector with internal thread, preferably a vertical nut, and 201 represents a slab, preferably a concrete slab.

[0060] In an embodiment, the system that enables the connection of the several accessories is incorporated into the structural base before the concrete is applied, ensuring that the positions provided for validating the structural and functional behavior are met. These elements are embedded in the thickness of the slab. The production process uses this system, by using the shaft in the device, to ensure that the product is materialized on a perfectly flat base and all the movement of the module in the productive space involves assembling the accessories with wheels using the same device embedded in the slab. It is possible to apply these two accessories to the prefabricated module simultaneously, which is one of the solution's relevant features, since the use of the shaft makes it possible to suspend the module at these points, ensuring that it is easy to couple and remove the accessories from the wheels without any supplementary means.

[0061] Figure 4 shows a schematic representation of an embodiment of a base for moving and leveling a prefabricated room module connected to an external wheel assembly, where 001 represents a horizontal rod, preferably a horizontal threaded rod, 002 represents a fastening connector with internal thread, preferably a horizontal nut, 003 represents a leveling connector with internal thread, preferably a vertical nut, 004 represents a lateral profile, 006 represents a horizontal screw, 009 represents an external moving element, such as for example an external wheel assembly, and 105 represents a slab.

[0062] Figure 5 shows a schematic representation of an embodiment of a base for moving and leveling a prefabricated room module connected to a connection component for lashing belts, e.g. for road transport, where 001 represents a horizontal rod, preferably a horizontal threaded rod, 002 represents a fastening connector with internal thread, preferably a horizontal nut, 003 represents a leveling connector with internal thread, preferably a vertical nut, 004 represents a lateral profile, 006 represents a horizontal screw, and 008 represents a connection component for lashing belts.

[0063] Once the module has been produced, the device is the support base for a new accessory that speeds up and ensures the correct attachment of the modules during transport. Lashing the modules is customary in order to ensure that they are correctly fixed to the means of transport, but it is usually done on the basis of the operator's experience and there are no predetermined connection points for that purpose, which introduces an additional risk variable for the safety and integrity of the module. With this mechanism incorporated into the slab and with the lashing accessory in transport, these risks are pre-assessed and mitigated to avoid any scenario of uncertainty.

[0064] In an embodiment, once on the construction site, the process of unloading begins with the removal of the lashing accessories and the subsequent placement of the moving accessories, thus allowing this process of placing the moving elements to be carried out close to the ground in a more controlled environment, with the module ready to be lifted and placed on the respective floor. Carrying out this activity at this stage also allows to simplify the process of placing the module on the unloading platform, since other systems would require this process to be done on the unloading platform itself, coordinating the crane's movements with the position of the moving element. Once unloaded on the destination floor, the module is moved into its position.

[0065] Figure 6 shows a schematic representation of an embodiment of a leveling of the base for moving and leveling, where 001 represents a horizontal rod, preferably a horizontal threaded rod, 002 represents a fastening connector with internal thread, preferably a horizontal nut, 003 represents a leveling connector with internal thread, preferably a vertical nut, 004 represents a lateral profile, 005 represents a nut for moving the vertical threaded shaft, and 007 represents a vertical threaded shaft.

[0066] In an embodiment, once the module has been placed in its final planimetric position, the shafts applied on the device incorporated in the module are used to initially raise the module, which is then supported only by the rods. This support configuration allows the movement accessories to be removed without using any other auxiliary means. Once the wheels have been removed, the shafts that allowed the module to be lifted also allow it to be lowered to the level predefined in the design, ensuring that the modules are perfectly leveled.

[0067] Figures 7A e 7Bshow a schematic representation of an embodiment of a device for coupling to a prefabricated room module for moving and leveling the module with and without a threaded rod, where 001 represents a horizontal rod, preferably a horizontal threaded rod, 203 represents a lateral profile, preferably a closed profile with rectangular or square tubular shape, and 205 represents a fastening connector with internal thread, preferably a nut that is configured for being connected to an accessory, namely an external moving element.

[0068] In an embodiment, the accessories are connected by larger screws which tighten the nut, 205. The nut, 205, is previously welded to a rod, e.g. a metal pipe. This solution is less expensive in terms of costs and production process, but is applicable in situations where the order of magnitude of the loads applied is smaller.

[0069] In an embodiment, each connection point, i.e. a set of two horizontal and one vertical nut, of the moving system was designed for a load of 500kg. Based on the weight of the module, the number of components required is defined, allowing to have a solution adaptable for each solution.

[0070] In the case of moving higher loads, the dimensions of the components can be increased / enhanced so that they can withstand greater loads.

[0071] Figure 8 shows a schematic representation of an embodiment of a device for coupling to a prefabricated room module for moving and leveling the module with an external wheel assembly attached.

[0072] Figure 9A and 9B show a schematic representation of an embodiment of a device for supporting, moving and leveling of said base, where 002 represents a fastening connector with internal thread, 003 represents a leveling connector with internal thread, and 004 represents a lateral profile.

[0073] In an embodiment, the details of the design and functionality of the system of adjustable compartments allow the safe transportation of modular components of various sizes and shapes.

[0074] This solution is applicable to any type of POD, by checking and defining the quantity and positioning of the components. One of the characteristics of the solution is precisely its scalability. Shape does not represent a limitation as the device is integrated into the solution, so the number and positions in which the components should be placed are defined.

[0075] In an embodiment, public utilities, i.e. the water and electricity connections, of the prefabricated room module are connected to the systems existing in the house after leveling and fixing the module.

[0076] In an embodiment, after leveling and connecting to the public utilities, the prefabricated room module is anchored or fixed to the floor and / or to the walls of the house. This step is essential to ensure that the module stays in place and does not move over time.

[0077] In an embodiment, the number of support points and their position is defined according to the volume, weight and / or maneuvers to be performed with the prefabricated module. There is therefore great adaptability to the size and weight of the prefabricated module in question.

[0078] In an embodiment, the lashing and moving accessories are coupled by using two screws, and the placement operation is carried out using a mechanical means. This operation is carried out on a stable base with no risk to the operator. The placement points are perfectly identified and there is no possibility of errors when coupling the accessories. This way, the accessories are easier to attach to the prefabricated modules.

[0079] The present solution is moved laterally, which avoids the need to place elements below the modular unit. In this way, the ratio between the maximum height of the module and the free height between the floor slabs of the building is maximized.

[0080] In an embodiment, the difference between the maximum height of the module and the free height between the floor slabs of the building is at least 3cm, for cases where only the moving system is placed. Preferably, the maximum is 10 cm in order to take into account the tolerances associated with the construction.

[0081] In an embodiment, in order to remove the moving accessories, it is necessary to slightly elevate the prefabricated module. This operation is safeguarded by the solution presented, comprising the thread that receives the threaded shaft for lifting and altimetric adjustment of the module.

[0082] The present invention relates to a device for moving and leveling a prefabricated room module.

[0083] The device allows the efficient transportation of room modules, e.g. living rooms, bedrooms, bathrooms, prefabricated for installation, while ensuring the proper leveling for different types of floors, in the desired locations.

[0084] The term "comprises" or "comprising" whenever used herein is intended to indicate the presence of stated features, elements, integers, steps and components, but not to preclude the presence or addition of one or more other features, elements, integers, steps and components, or groups thereof.

[0085] The present invention is, of course, in no way restricted to the embodiments described herein and a person with average skills in the art may foresee many possibilities for modifying it and replacing technical features with equivalent ones, depending on the requirements of each situation, as defined in the appended claims.
