Definitions

  • the present disclosure relates to a hybrid building system, a hybrid building and a method of constructing a hybrid building.
  • the present disclosure also relates to first and second building sections forming part of such buildings.
  • Prefabricated housing has been developed in an attempt to meet these challenges.
  • Prefabricated housing may refer to buildings having built in components (e.g. panels), modules, or transportable sections.
  • commercially available prefabricated houses and methods of construction do not suitably address the problems identified above.
  • Examples of known prefabricated housing include so-called “modulai” buildings. These are buildings which are assembled using an arrangement of prefabricated units or sections that have been constructed in a factory or facility, and then shipped to a final location for the building. Whilst manufacture of the building units in a factory addresses some of the problems with conventional construction methods, there remain significant disadvantages with buildings of this type.
  • the building units each comprise an internal void or volume which defines part of the total volume of the assembled building, and are transported to the building site in that form.
  • a consequence of this is that there is a requirement to construct and store all of the finished building units at the factory location, which takes up significant space. A large premises is therefore required.
  • Some modular buildings comprise pre-constructed building units of this type, and a flat panel or frame-type structure which is connected to the pre-constructed building unit at the final location, in order to form the completed building.
  • these panel or frame-type structures still have to be stored at a factory, and transported to the final location for subsequent assembly. Although this can reduce the volume of some of the structures that have to be transported, they are still comparatively bulky, and can be relatively costly to manufacture.
  • the part of the building formed from the flat panel/frame-type structure is not self-supporting, and relies on the pre-constructed unit for support. As a result, the preconstructed unit must be placed at the final location before any further assembly work can take place.

  • the residential building is a hybrid in that part of the building is an on-site construction at the final location (the first building section), and part is constructed separately and transported to the final location (the second building section).
  • the building is formed at the final location by connecting the first and second building sections together.
  • first building section being an on-site construction. This should be taken to mean that the first building section is constructed at the site using an arrangement of parts, components and/or materials which are provided at the site. This is in contrast for example to modular buildings which are assembled at a final location using building units or sections that have been constructed off-site (e.g. in a construction facility or factory) and which, in their constructed form, define part of an internal volume of the finished building.
  • the second building section may be constructed away from the final location.
  • the second building section may be an offsite construction, and may be transportable to the site in the substantially assembled form.
  • the first building section may be constructed first, and the second building section subsequently connected to the first building section to form the building.
  • the second building section may be located on the site, and the first building section subsequently constructed and connected to the second building section (suitably during the construction process).
  • the first building section may be built on or from the second building section, for example using the second building section as a support or platform for part or parts of the first building section.
  • the second building section will generally be constructed away from the site.
  • Options include a factory or facility that is distanced from the site, and accessible by road and/or rail from the site.
  • Other options include a factory or facility provided on or as part e.g. of such a larger building site (but distanced from the plot), for constructing a plurality of second building sections which are to be used in the construction of a plurality of buildings.
  • a hybrid residential building comprising the first and second building sections offers numerous advantages over prior buildings and associated construction techniques, including over prior modular buildings.
  • construction of the first building section at the final location enables the use of conventional (non-modular) construction techniques. These can be relatively simple, enabling construction of the first building section in a time and cost-effective manner. A relatively large proportion of the total building volume may be provided by the first building section, and so construction using conventional techniques can be beneficial in minimising costs.
  • Prior units of this type each define an internal void or volume which forms part of the total volume of the assembled building. This can provide the related benefits that: it is not necessary to provide a large assembly space within the facility for constructing the modular building units; it is not necessary to transport such bulky units from the facility to the site (e.g. by road/rail); and it is not necessary to provide space for storing such bulky units either at the facility, or at the site where the building is to be formed.
  • the second building section can be transported on-site for use in construction of the hybrid residential building as and when required.
  • the second building section may comprise more complex parts of the finished building, such as a staircase/stairs, bathroom, room, and a W. C./washroom, amongst other things. Construction away from the final location by dedicated workers may facilitate the construction process and improve quality control. Limiting such construction to the more complex second building section enables these positive outcomes to be achieved whilst minimising transportation of bulky components to the final location. It may also simplify construction of the first building section.
  • a balance can therefore be reached in which the first building section can be constructed at the final location in a cost and time-effective manner using simple conventional techniques, whereas the more complex second building section can be constructed in a reliable and quality -controlled manner whilst minimising the size (volume) of components that need to be transported to the final location.
  • Wear and tear occurring e.g. due to the movement of people between the upper and lower living spaces may occur primarily (and optionally entirely) in the second building section.
  • the second building section may be releasably connected to the first building section. Constructing the second building section away from the final location and making it transportable means that it can readily be removed and replaced, for example in the event of maintenance being required to address such wear and tear, and/or if replacement of the section is required.
  • Providing an access route/access passing through the second building section, and the second building section so that it provides the specified communication may also reduce the complexity of the first building section, enabling it to be constructed relatively quickly and cheaply.
  • the second building section may comprise or contain a staircase/ stairs, which may: define at least part of the access route; provide the required access; and/or facilitate the internal volume relationship/intemal communication. Provision of the staircase in the second building section may enhance the structural stiffness/ rigidity of the building section, which may in- tum facilitate its transportation.
  • the staircase/stairs may be in or may provide part of the circulation space.
  • Construction of the second building section away from the final location may facilitate reliable construction in a controlled environment, with enhanced quality control.
  • the first building section may be of any type that is suitable for on-site construction, but may exclude modular-type constructions.
  • a modular-type construction in this context, should be taken to mean a construction in which all (or substantially all) of a final volume of a building is pre-formed, comprising a series of building parts or units each defining a portion of the final volume of the building, for subsequent transportation to a final location for the building.
  • the first building section may be of a construction selected from the group comprising: a blockwork/masonry construction e.g. of clay bricks and/or cement blocks; a timber frame and blockwork/masonry construction; a timber frame and cladding construction; a metal frame construction (optionally comprising panels coupled to the frame e.g.
  • the first building section may be or may comprise a kit of building materials (e.g. blocks, timber frame components, metal structural elements) which can be used in the on-site construction of the building section.
  • the second building section being transportable to the final location in a substantially assembled form. This may be taken to mean that the second building section is constructed to a state in which: it can be transported safely (i.e. it has sufficient structural integrity/rigidity for transport purposes); minimal further work is required to be carried out on the second building section in order to connect it to the first building section; and/or minimal (optionally no) further work is required to complete a portion of the building formed by the second building section.
  • Such further work may be of a structural and/or weatherproofing nature, and may exclude work associated with a final fit-out of the second building section, for example of a decorative nature (in particular the application of ‘perishable’ materials such as plaster/plasterboard, decorative panels and surface finishes such as paint).
  • the second building section may comprise a plurality of subsections or units which may be configured to be fitted or coupled together to form the completed building section.
  • the subsections may be independently transportable, and connected at the site to form the completed second building section.
  • the reference to the second building section being transportable to the final location in a substantially assembled form should be taken to mean that the subsections are each transportable in a substantially assembled form (and does not require the subsections to be connected prior to transport to the final location).
  • the reference to the second building section being transportable to the final location in a substantially assembled form therefore encompasses constructing such subsections to substantially assembled forms, transporting the subsections to the final location in their assembled forms, and then connecting the subsections at the final location to form the second building section.
  • the first building section may have a total internal volume, which may be the sum of: the internal volume defined by its lower storey; and the internal volume defined by its upper storey (or all its storeys where there are more than two). If there is only one storey then the total internal volume is the volume of that storey.
  • the hybrid residential building may have a total internal volume, which may be the sum of the total internal volume of the first building section, and the internal volume of the second building section.
  • the second building section may define at least around 15% of the total internal volume of the building, optionally at least around 20%, optionally at least around 25%, optionally at least around 30%, optionally at least around 35%, and optionally up to around 40% of said volume .

  • a ratio of the total internal volume of the building provided by the second building section relative to the total internal volume of the building provided by the first building section may be around 15:85, optionally around 20:80, optionally around 25:75, optionally around 30:70, optionally around 35:65, and optionally around 40:60.
  • a particularly preferred internal volume provided by the second building section may be in a range of around 28% to around 36% (and so first building section internal volume of around 72% to around 64%, and ratio in a range of around 28:72 to around 36:64).
  • the second building section could provide up to around 50% of the total internal volume of the building (and so around a 50:50 ratio of second building section volume relative to the total).
  • Arranging the second building section to provide between around 15% to 40% of the total internal volume of the building, and in particular between around 28 and 36% of the internal volume, may provide sufficient volume for a usable space (optionally a living space) within the second building section, and for the required access to be provided passing through it. Restricting the proportion of the total living space provided by the second building section to no more than around 36% may also facilitate construction of the second building section, and/or its transportation to the final location (by effectively limiting its size).

Cementitious materials are particularly suited to use in 3D printing construction techniques, but other materials may be, or may become, suitable.
  • Structural panels such as SIPs typically form their own structural support, but can optionally be used in conjunction with a metal frame construction. It will be understood that panels with sufficient structural strength and/or rigidity may be employed which may dispense with the need for a metal (or other material) frame construction to support the panels.
  • Another construction option for the first building section involves the use of site-poured time-setting materials (e.g. of a cementitious material such as concrete).
  • a particular option may be reinforced concrete. This typically involves the construction/positioning of moulds known as shuttering at the final location, into which the time-setting material is poured (optionally following location of reinforcing rods in the moulds), and which cures to form structural components.

However, another option includes the shaping of edge regions of the panels to define connectors which engage with a corresponding connector on the adjacent panel(s). This is shown in Figure 37, each panel 1658’ comprising respective male 1660’and female 1662’ connectors.
  • a female connector 1662’ on one panel receives a male connector 1660’ on an adjacent panel for connecting the two together.

  • a solid wall construction in this context, may be one in which the load bearing support structure of the relevant wall or walls accommodates substantially an entire span of the relevant wall (which may be taken in width and height directions). This contrasts for example with a steel or other frame structure, in which open cells or spaces exist between structural support members of the load bearing structure.
  • Examples of such a solid wall construction may include blockwork, structural panels (e.g. concrete panels, SIPs) and 3D printed walls.

Where the first building section comprises a lower storey and at least one upper storey, different storeys may be of different constructions, or at least partly different. All of the construction options described above represent different methods for forming the load-bearing walls, and/or the load-bearing structure of such walls, of the first building section. For example, in the case of a load-bearing wall comprising a blockwork construction, the blockwork (e.g. bricks and/or cement blocks) form the load-bearing structure of the wall.

  • a construction option for the second building sections described in this document is the provision of a metal (e.g. steel) frame support structure, suitably forming external walls of the second building section. Examples are shown in Figures 29 and 33. As also explained elsewhere, it will be understood that one or more external wall of the second building section may form an internal wall of the first building section, and/or in the constructed building (when the sections are connected). Examples are shown in Figures 2, 17 and 29.

This may provide a homogeneous support structure, which may assist in distributing loads applied to the section across the structure. Such may apply particularly to hot-formed structural elements. Other joining options include mechanical fixings (e.g. nut and bolt), and adhesives.
  • Another construction option for the second building section is the use of timber/wood (or wood-based products/ composites) for the frame support structure.
  • wood-based products/composites include laminates such as plywood, and products made from wood fibres or particles.
  • Structural elements of the frame may be connected using mechanical fixings and/or adhesive.

Abstract

Sont divulgués des bâtiments hybrides, des systèmes de bâtiment hybrides et des procédés de construction de bâtiments hybrides. Sont également divulgués des première et seconde sections de bâtiment faisant partie de tels bâtiments. Un tel bâtiment résidentiel hybride (1600) comprend une première section de bâtiment (1610) et une seconde section de bâtiment (1620). La première section de bâtiment est une construction sur site à un emplacement final du bâtiment et comprend un volume interne (1613) qui constitue un espace de vie (1615) à l'intérieur du bâtiment. La seconde section de bâtiment délimite un volume interne (1623) et peut être transportée vers l'emplacement final sous une forme sensiblement assemblée. Les première et seconde sections de bâtiment sont reliées au niveau de l'emplacement final pour former le bâtiment. La première section de bâtiment comprend une pluralité de murs porteurs (1604 à 1607 et 1658) et la seconde section de bâtiment comprend une pluralité de murs porteurs (1608, 1609, 1673 et 1673a), les murs porteurs des première et seconde sections de bâtiment comprenant chacune une structure de support porteuse (1604a ; 1696), la structure de support porteuse d'au moins certains des premiers murs porteurs de section de bâtiment étant différente de la structure de support porteuse d'au moins certains des seconds murs porteurs de section de bâtiment.
