Description

[0001] MODULAR BUILDING CONNECTION SYSTEM

[0002] Technical Field of the Present Invention

[0003] The present invention relates to a modular building connection system. More particularly, the present invention relates to a modular building connection system comprising a conical connector, receiving connector, and rod in order to provide structures that can be assembled remotely in a quick and accurate manner, and that have enhanced structural strength and can bear internal and external forces evenly.

[0004] Background of the Present Invention

[0005] Modular buildings are prefabricated buildings that are formed from one or more building modules. The building modules may comprise a load bearing structure, mechanical, electrical, or plumbing components, interior finishes, and exterior cladding. The building modules are constructed off-site (e.g., in a factory) and then transported to the building site so as to be assembled into a modular building. The building modules can be attached to each other side-by-side, end-to-end, or stacked on top of each other in order to form modular buildings of varying shapes and sizes. Modular buildings are advantageous in that they require minimal construction on-site as they are preconstructed, which allows for increased construction efficiency, consistent building designs, and the ability to service remote locations.

[0006] Typically, building modules incorporate modular building connection systems in order to enable on-site assembly of said modules. One of the problems related to the construction of modular buildings is the inability of the modules to resist and transmit the large forces resulting from wind and seismic activities and the large compression loads resulting from the effect of gravity on the building and occupants. These effects are greatest in the lower floors and rise in proportion to increasing height and narrowness of the building, so forces are also largest at the lower floors. Another problem is ensuring the correct alignment of the building modules in vertical and horizontal positions. In the cases where workers have to use their eyes or plumb lines to measure vertical and horizontal orientations, this may lead to inaccuracies and a reduction in the structural integrity of the buildings. In the cases that the modules are placed in an orientation significantly away from the vertical or horizontal orientations, then the building overall may be significantly weakened.

[0007] Among others, prior art publications in the technical field of the present invention may be referred to as WO 2014 / 127472 and WO 2017 / 027965 which disclose a connector assembly having an upper connector, a pin coupling the upper connector to a lower connector and a gusset plate sandwiched between the upper and lower connectors. The gusset plate has two faces, where the first face can be in contact with lower connector and the second face can be contact with the upper connector. In addition, the gusset plate is provided with through holes, which align with apertures on the upper connector and lower connector, allowing fastening of the connectors using fastening means.

[0008] Another reference can be given as US 6,837,016 which discloses a columnbeam building frame structure, wherein columns and beams are interconnected through collars that encircle columns at the nodal points of attachments between the columns and beams. Each collar includes inner and outer components which seat and gravity-lock together during frame construction. Tension bolt and nut assemblies lock the inner and outer collar components together.

[0009] Another reference can be given as EP 3 913 159 which discloses a system of assembling a modular building structure. The building structure includes a first building module having at least one first male connector, a second building module having at least one second male connector, a connector plate comprising a first aperture arranged to receive the first male connector of the first building module, and a second aperture arranged to receive the second male connector on the second building module, such that upon receipt of the first and second male connectors the first and second building modules are coupled together.

[0010] Another reference can be given as CN 217054490 which discloses a building module including a plurality of beams, uprights and sealing plates. The sealing plates are connected with the end of the column and comprise a first positioning hole and a first connecting hole. Said first positioning hole is used for a positioning cone to pass through and said first connecting hole is used for connecting with the connecting piece.

[0011] Another reference can be given as US 3,824 750 which discloses a mechanical connector system for interjoining and aligning column sections. The system comprises a unitary cast connector having a planar platform portion for abutting engagement with adjacent ends of the column section members, a conical guide portion extending outwardly on one side of the platform portion and a polygonal flange portion protruding from the opposite side thereof for fitting engagement with the interior walls of the column section members. Ancillary tie-bolt means are also utilized between structural support framing members associated with the column sections to lock the latter in position.

[0012] Another reference can be given as US 9,366,020 which discloses a modular unit connection system for joining together a plurality of box-shaped modular units to form a single or multistory building. The modular building units have elongated hollow structural framing members at their vertical corners. The vertical corner members lie within the planes formed by the side walls of the modular units. The modular units are connected at their vertical corner members with generally flat connection plates. Threaded tension rods extend through the hollow vertical corner members and are coupled to tension rods running through the hollow vertical corner members of vertically aligned modular units.

[0013] Another reference can be given as WO 2009 / 138770 which discloses a connector system which is capable of being used to connect construction modules in a substantially horizontal and / or substantially vertical manner. Said connector system comprises a square-shaped central base and frustoconical sections centrally mounted onto said base. Said conical sections comprise a central passageway in order to facilitate the positioning of construction modules. The walls of the frustoconical act as guide members for further positioning of construction modules.

[0014] Other references can be given as US 4,694,621 and US 6,871,453 which disclose systems for constructing buildings utilizing a conical connector to fasten rods connecting structural members of a building. The conical connector is circular in section, with an axial bore, a flat top surface and bottom surface perpendicular to the bore, a ring-shaped flange midway between the top surface and the bottom surface, and a sloping surface between the top surface and the flange and between the bottom surface and the flange, forming a cone. The sloped surface of the connector engages a recess in a structural member of the building. A tensioning mechanism passing through the bore in the connector applies a coupling force to hold the connector against the structural member. The present invention proposes a modular building connection system to improve on the solutions present in the art. The modular building connection system comprises at least one conical connector, at least one receiving connector configured for receiving said conical connector and a tensioning rod configured to connect said conical connector and receiving connector and bear the forces on the modular building connection system. Said conical connector has a generally frustoconical shape, which facilitates the alignment of building modules, allowing the orientation and assembly of building modules in a quick and accurate manner. The conical shape further allows said modular building connection system to distribute the external lateral forces on the modular building, such as due to wind or earthquakes, along the surface of said conical connector and convert said lateral forces into axial forces, which can then be borne by the tensioning rod. The present invention further proposes a building module comprising said modular building connection systems, and a modular building construction comprising said building modules.

[0057] Figures 1A and 2 demonstrate different embodiments of a modular building connection system (10) according to the present invention. Said modular building connection system (10) comprises at least one conical connector (11), a receiving connector (12) and a rod (not pictured). Said conical connector (11) has a generally frustoconical shape and comprises a connector bore (13) extending axially (22) through said connector in order for a rod, such as a tensioning rod (not pictured) to be inserted thereinto. Said receiving connector (12) has a generally cubic shape and a receiving space (23) within that defines a generally frustoconical volume matching the shape of said conical connector (11), whereby said conical connector (11) can be inserted into said receiving connector (12). Said receiving connector (12) also comprises a receiving bore (14) extending axially (22) through said connector in order for said rod, such as a tensioning rod (not pictured) to be inserted thereinto. Said receiving connectors (12) are configured to be attached to the building module (50). Preferably, said receiving connectors (12) are configured to be attached to the upper and lower corners of the building modules (50) for joint connections. However, the skilled person will appreciate that said receiving connectors (12) can be placed on other positions on the building modules (50).

[0058] The conical shape of said conical connector (11) provides many advantages. For example, the tapered shape of said conical connector (11) facilitates the alignment of building modules (50), particularly when said building modules (50) are positioned using a crane. Therefore, said conical connector (11) and said receiving connector (12) of said modular building connection system (10) can be aligned and engaged remotely by the user, allowing the orientation and assembly of building modules (50) in a quick and accurate manner.

[0059] Further, said modular building connection system (10) can be used in positions where access is limited or difficult, allowing a user to assemble building modules (50) in positions which would be difficult to achieve were access to the components of said modular building connection system (10) can were required, such as in cases where the corners of multiple building modules (50) are assembled next to each other (Figures 6, 7, 11 and 12). As another advantage, the conical shape allows said modular building connection system (10) to distribute the external lateral forces on the modular building, such as due to wind or earthquakes, along the surface of said conical connector (11) and convert said lateral forces into axial forces, which can then be borne by the tensioning rod. Said modular building connection system (10) further comprises a washer (15) in order to fasten said rod to said modular building connection system (10). Said conical connector (11) and receiving connector (12) also comprise at least one connector fastening bore (17) and receiving fastening bore (18) respectively, whereby said conical connector (11) and receiving connector (12) can be fastened to each other via fastening bolts (19) and fastening washers (20).

[0060] In an alternative embodiment, said modular building connection system (IO7) comprises at least one dual conical connector (21), which is comprised of two conical connectors (11) attached to each other at the base and at least one pair of receiving connectors (12). Dual conical connectors (21) can be used in order to connect building modules (50) to each other.

[0061] Said modular building connection system (IO7) further comprises a connector plate (16) for providing better fit. Said connector plate (16) comprises at least one hole (24) to receive said conical connector (11) or dual conical connector (21). Said connector plate (16) is configured to meet the geometric requirements of the joint connection and provides even spacing and horizontal bracing between adjacent building modules (50), eliminating relative movements between said building modules (50).

[0062] Figure IB demonstrates a ground connector (55), which can be used in order to connect building modules (50) to the ground. A ground connector (55) comprises ground rods (57) to be planted into the ground where the modular building is desired to be built. Said ground connector further comprises a ground plate (56), balance nuts (59), a balance plate (58), chemical anchors (60), at least one conical connector (11) and at least one connector plate. An equivalent number of receiving connectors (12) to conical connectors (11) can be attached to the building modules (50) for joint connections. Said ground connector (55) is configured to meet the geometric requirements of the joint connection.

[0063] In some embodiments, a series of modular building connection systems (10, IO7) are attached to each other, for example at the corners of multiple building modules (50). Said modular building connection systems (10, IO7) may be attached linearly, in an L shape, in a 2 by 2 orientation or any other orientation required.

[0064] Figure 3 demonstrates a connection between a building module (50) and a single ground connector (55). In a basic form, a building module (50) comprises a plurality of columns (51) and horizontal structural members (52) arranged in a box-shaped frame. Said building module (50) may further comprise other structural members, floor plates, ceiling materials, interior and exterior finishing materials, and facilities; however, these elements are not shown in the Figures for simplicity. The specific types and configurations of columns (51) and horizontal structural members (52) described herein are meant to be illustrative and not meant to limit the scope of utility of the invention. The skilled person will appreciate that the present invention can be used with a wide range of types and configurations of columns (51) and horizontal structural members (52) known in the art.

[0065] Said column (51) comprises a first column sidewall (53) and a second column sidewall (54) whereby said receiving connector (12) is attached to said building module (50). Said receiving connector (12) can be attached to column (51) via fasteners, welding, or any method known in the art. The building module (50) is lowered onto ground connector (55) so that said conical connector (11) enters into the receiving space (23) of receiving connector (12). The building module (50) is then secured to the ground connector (55) via a tensioning rod (not pictured). Figures 4 to 7 demonstrate connections between building modules and ground connectors (55) having different geometries.

[0066] Figure 8 demonstrates a connection between two building modules with a dual conical connector (21). Dual conical connectors (21) are used in order to stack building modules (50) on top of each other. The lower building module (509 comprises a receiving connector (127) attached to the top of its column (517), while the upper building module (50) comprises a receiving connector (12) attached to the bottom of its column (51). The bottom cone of the conical connector (21) is inserted into the receiving space (239 of the receiving connector (127) and a connector plate (16) is positioned on top of receiving connector (127). Then the upper building module (50) is lowered so that the top cone of the conical connector (21) enters into the receiving space (23) of receiving connector (12) and so that said connector plate (16) is sandwiched between said receiving connectors (12, 127). The building modules (50, 507) are then secured to each other via a tensioning rod (25). Figures 9 to 12 demonstrate alternative embodiments connections between connection between building modules with dual conical connectors (21) having different geometries.

[0067] In addition, the connector bore (13) of a dual conical connector (21) attached to a receiving connector (12) on the top of a building module (50) can be used to attach a lifting means, such as an eyebolt, to said building module (50) whereby said building module (50) can be lifted and moved as required.

[0068] Figures 13A and 13B demonstrate a connection of a lashing means to a building module (50) via the modular building connection system (10). In a preferred embodiment, said lashing means is a lashing plate (70) having a stepped form and comprising an attachment bore (71) whereby said lashing plate (70) can be attached to the conical connector (11) of modular building connection system (10) by a bolt, and an attachment bore (71) whereby said lashing plate (70) can be attached to a transport means, such as a truck, by chains or ropes or any other means known in the art, thereby securing said building module (50) to said transport means.

[0069] Figure 14 demonstrates a connection of an alternative embodiment of a lashing means to a building module (50) via the modular building connection system (10). Said means is in a lashing element (73) comprising an attachment bore (717) whereby said lashing element (73) can be attached to the conical connector (11) or receiving connector (12) of modular building connection system (10) by a bolt, and a lashing eye (74) whereby said lashing plate (70) can be attached to a transport means, such as a truck, by chains or ropes or any other means known in the art, thereby securing said building module (50) to said transport means. Figures 15A and 15B demonstrate the position of said lashing element (73) in transfer and anchoring positions, respectively. In the transfer position, said lashing element (73) is attached to the side of the building module (50) via said receiving connector (12). After transfer to the transport means is completed, said lashing element (73) is removed from the side position and reattached to the bottom of the building module (50) via said conical connector (11) in order for said building module (50) to be secured to the transport means.

[0070] Depending on the location within the modular building, the modular building connection systems (10) may be subjected to different amounts of forces. For example, modular building connection systems (10) located near the bottom of the modular building are subjected to greater weight forces than modular building connection systems (10) located near the top of the modular building. In a preferred embodiment of the invention, a plurality of modular building connection systems (10) are used in a connection location of the building module (50) for building modules (50) located near the bottom of the modular building in order to account for the extra forces.

[0071] In a preferred embodiment of the invention, said modular building connection system (10) is made of any suitable strong material such as a metal, alloy and / or composite material. Said modular building connection system (10) can be made in any desired size based on the requirements of the modular building.

[0072] The present invention further proposes a building module (50) comprising at least one said building connection system (10) described above in the upper and lower corners thereof, whereby said building modules (50) are attachable to each other.

[0073] The present invention further proposes a modular building comprising one or more building modules (50) as described above. The modular building constructed in the manner can efficiently transfer external and internal forces. Each part of said modular building bears the forces evenly and has enhanced structural strength. In addition, the modular building can be assembled remotely in a quick and accurate manner.

[0074] The present invention further proposes a method for connecting building modules (50) in a substantially vertical manner, comprising the steps of: a) coupling a receiving connector (127) to the top of a lower building module (509, b) coupling a receiving connector (12) to the bottom of an upper building module (50), c) inserting the bottom cone of a conical connector (21) into the receiving space (23Q of the receiving connector (127), d) positioning a connector plate (16) is on top of receiving connector (129, e) lowering the upper building module (50) so that the top cone of the conical connector (21) enters into the receiving space (23) of receiving connector (12) and so that said connector plate (16) is sandwiched between said receiving connectors (12, 127), and f) securing the building modules (50, 507) are to each other via at least one tensioning rod (25).
