Definitions

  • the present teachings relate to a modular building unit.
  • Modular buildings are prefabricated buildings that are formed from one or more modular units. These modular building units are manufactured in a factory away from the building site, and then transported to the building site so as to be assembled into a modular building. The modular building units are constructed so as to be capable being attached side-by-side, end-to-end, or stacked, which enables modular buildings to be produced having a variety of shapes and styles using a single repeatable modular building unit.
  • the modular building units After the modular building units have been assembled, e.g. using a crane, the modular building units are connected together. It is then necessary to seal the joints between adjacent modular building units, for example to prevent draughts and the ingress of rain water into the modular building, and to increase the thermal insulation of the modular building by reducing heat escaping between the adjacent modular units.
  • the modular building units are designed to have sufficient strength/rigidity to comply with the local laws of the country in which the modular building is to be constructed.
  • existing modular building units may not be suitable to be used in the construction of buildings as they may not comply with local wind, heat, and snow load requirements.
  • the present teachings seek to overcome or at least mitigate one or more problems associated with the prior art.
  • a first aspect of the teachings provides a modular building unit comprising: a floor assembly comprising a substantially rectangular base frame for supporting a floor panel thereon; a roof assembly comprising a roof frame for supporting a roof panel thereon; and a plurality of corner assemblies each comprising an upright column extending between the base frame and the roof frame, wherein the roof frame is formed from a plurality of elongate roof members extending between adjacent corner assemblies, wherein each elongate roof member comprises an inner wall and an outer wall connected by a base to define a channel extending along the elongate roof member, and wherein the plurality of roof members are arranged such that the plurality of channels form a gutter extending at least partially around the roof frame.
  • Each of the roof frame members are provided as a substantially U-shaped beam so as to form a channel therealong.
  • the roof frame of the modular building unit is able to both support a roof panel and also to provide drainage to drain rain water away from the roof assembly without any additional components being mounted to the roof frame/modular building unit. This helps to provide a more compact roof assembly and so to provide a more compact modular building unit.
  • the base frame may be substantially rectangular.
  • the roof frame may be substantially rectangular.
  • the gutter may extend around an entirety of the roof frame.
  • Each of the plurality of corner assemblies may be interposed between adjacent roof frame members and may define a flow path therethrough for connecting the channels of adjacent roof frame members.
  • One or more of the corner assemblies may comprise a drainage conduit for draining water received in the gutter.
  • Providing a drainage conduit, i.e. a drain pipe, that is positioned within, or contained within, an upright column of the modular building unit further improves the ability of the modular building unit to drain rain water away from the roof assembly without any additional components being mounted to the modular building unit.
  • the modular building unit may comprise a drainage outlet at or near a downstream end of the drainage conduit for discharging water received in the gutter out of the modular building unit.
  • the drainage outlet may be provided on the floor assembly, e.g. on a base frame member.

  • the outlet may enable the collected rainwater to be discharged outside of the modular building unit, for example into a tank for storage, or into a further modular building unit or below the modular building unit.
  • Providing a drainage outlet in the base assembly enables the water to flow down to the bottom of the modular building unit, which allows the water to be drained into a unit below, if the modular building unit is stacked on top of another unit.
  • the modular building unit may comprise an overflow outlet for discharging built up water from the gutter.
  • the overflow outlet may be positioned at or near an upstream end of the drainage conduit, e.g. in a column of a corner assembly or a roof frame member.

  • the air cavity 68 increases the compressibility of the seal 42.
  • the roof panel 22 compresses the seal 42, which helps to improve the seal formed between the roof frame 20 and the roof panel 22.
  • a base frame member 16 is illustrated.
  • Each of the base frame members 16 is provided in the form of an elongate box-section beams. This has been found to increase the rigidity and structural strength of the base frame 14, and so of the modular building unit 10 as a whole.
  • the base frame members 16 each include first and second upwards projections 70, 72.
  • the first and second upward projections 70, 72 extend in a direction towards the roof frame 20.
  • the first upward projection 70 is configured and arranged to act as an inner stop for the wall panels 28.
  • the second upward projection 72 is configured and arranged to act as an outer stop for the wall panels 28.
  • the first and second upward projections 70, 72 are arranged so as to define a lower channel for receiving a lower part of a wall panel 28 therein. This arrangement has been found to facilitate the fitting of wall panels 28 to the modular building unit 10 without requiring additional components to be fitted to the modular building unit 10.
  • the base frame 14 (i.e. the base frame members 16) are configured to support a floor panel thereon.
  • each of the base frame members 16 has an inward projection 74 for supporting a floor panel 76 thereon.
  • the inward projection 74 may be provided in the form of a substantially L-shaped member or a plate that is attached, e.g. welded, to the base frame members 16.
  • the inward projection 74 may be configured to form a seal against the floor panel 76. This arrangement helps to prevent moisture and vapours from entering into the modular building unit 10 from below.
  • the inward projection 74 may include a seal (not shown) on an upper surface thereof for engaging the floor panel 76.
  • the seal may be formed from a deformable material.
  • the deformable material of the seal may be a rubber, such a neoprene.
  • a modular building assembly is illustrated and is indicated generally at 100.
  • the modular building assembly 100 includes first and second modular building units 10 arranged adjacent to each other (i.e. side-by-side). It will be appreciated that the first and second modular building units 10 may both be modular building units as described with reference to Figures 1 to 4 .
  • a roof frame member 24 of each of the modular building units 10 are positioned adjacent to each other.
  • the modular building assembly 100 includes a roof cover 102 extending over the adjacent roof members 24. This arrangement provides a seal between the two modular building units 10.
  • the roof cover 102 is provided in the form of a cover plate 104 having first and second cover arms 106 arranged to extend around the adjacent roof members 24.
  • the roof cover also includes a fastening arrangement 108 for securing the roof cover 102 to the modular building assembly 100.
  • the fastening arrangement 108 includes a cover bracket 118.
  • the fastening arrangement 108 includes a connecting rod 110 connected to the cover bracket 118 via a fastener 112.
  • the provision of the cover bracket 118 enables the upper surface of the cover plate 104 to be free of apertures which helps to prevent the ingress of water into the modular building unit 10.
  • the cover bracket 118 is separate from the cover plate 104 and is connected to said cover plate 104.
  • the cover bracket includes opposing outwardly projecting flanges 20 that are received in corresponding openings (not shown) in the cover plate 104 so as to connect the cover bracket 118 to the cover plate 104.
  • the cover bracket 118 may be integrally formed with the cover plate 104. In further alternative arrangements, the cover bracket 118 may be omitted. In such arrangements, the connecting rod 110 may be connected to the cover plate 104 via welding, an adhesive, or via any other suitable means not requiring an aperture in the upper surface of the cover plate 104.
  • a first end of the connecting rod 110 extends through an aperture in the cover plate 104 and is secured thereto via the fastener 112.
  • a second end of the connecting rod 110 is secured to the roof frame 20.
  • the second end of the connecting rod 110 extends through an aperture in a mounting plate 114.
  • the connecting rod 110 is secured to the mounting plate 114 via a fastener 116.
  • the mounting plate 114 is arranged so as to abut against the roof frame 20 (i.e. against the roof frame members 24). This arrangement helps to improve the sealing of adjacent units, which, in turn, helps to prevent/minimise the ingress of water into a modular building assembly.
  • he fastening arrangement 108 is located within, and accessible from, an interior space defined by the modular building assembly 100 (i.e. by the first and second modular building units 10). Providing a fastening assembly that is operable from within the modular building assembly enables the roof cover to be attached without requiring an operator to work at height on the roof.
