Definitions

  • the present invention belongs to the technical field of building and construction; in particular, to the field of façade coverings. More particularly, the invention relates to, according to a first aspect thereof, a prefab panel for an off-site modular fagade, as well as, according to additional aspects, a modular façade including the above-mentioned prefab panel, and a method for making the modular façade.
  • curtain walling The construction system known as curtain walling is a building envelope intended to support only its own weight and withstand the effects of environmental forces such as wind. It is not intended to assist the structural integrity of the building.
  • curtain walling construction There are two main types of curtain walling construction: “stick” and “unitized”.
  • stick construction the curtain wall frame is constructed mainly on site with mullions and transoms supporting glass, spandrel panels, metal panels and brise-soleils, connected piece by piece. Each mullion is usually supported by floor or perimeter beams.
  • unitized construction on the other hand, the curtain wall is composed of large units that are assembled in the factory, shipped to the site and erected on the building.
  • Metal profiles such as aluminium profiles, steel profiles or profiles made from other suitable metals, may be used to form the frame, which is normally one-storey high. Opening vents, glazing and infill panels are built into units before being transported to site. As with stick construction, each unit is usually supported by the floor or perimeter beams.
  • the present invention relates to a unitized-wall simplified construction, involving a lesser weight and simplified assembling works.
  • the present invention discloses, according to a first aspect thereof, a prefab panel for a modular façade of a building, the prefab panel comprising: a frame structure; an outer cladding layer, made of plasterboard, attached to the frame structure; and attaching means for supporting the outer cladding to the frame structure.
  • prefab is to be understood as a “stand-alone solution” ready to be used, which represents a key added value in terms of easiness efficiency and cost reduction.
  • the frame structure comprises first and second horizontal profile(s), as well as first and second vertical profile(s).
  • the frame structure may further comprise third vertical profile(s) and/or third horizontal profile(s).
  • the first and the second vertical profile have a matching shiplap design, as well as the first and second horizontal profile have a matching shiplap design.
  • This allows any prefab panel to be joined to adjacent upper and lower prefab panels and to adjacent further right and further left prefab panels.
  • brackets are mountable to the first and second vertical profiles, for supporting the prefab panels, as explained below.
  • one bracket is used per first and second vertical profile, but the invention may alternatively involve a different number of brackets.
  • the brackets may either be attached to the to the first and second vertical profiles, all together making up the above-explained prefab panel, or alternatively the invention may be provided as a kit comprising: the frame structure; the plasterboard outer cladding attached to the frame structure through the attaching means; the horizontal profiles and the vertical profiles featuring shiplap design; and the brackets, as explained above, wherein the brackets are not mounted to the first and second vertical profiles, allowing installers to attach the brackets to said first horizontal and vertical profiles themselves for building the prefab panel.
  • a thermal insulator may be housed within the frame structure, opposite to the outer cladding.
  • the invention also relates to a modular façade comprising a plurality of the above-referred prefab panels assembled together, as well as a method of building the modular façade by assembling together the prefab panels.
  • the present solution aims at streamlining façade installation, reducing the timing and auxiliary resources used in a normal façade method. Based on this point, the main concept is the installation of the façade elements from each slab of the building with the safety measures required in each case.
  • the present invention combines the idea of a unitized curtain wall installation with a light weight façade made of plasterboard solution concept in order to improve both systems after this combination.
  • the invention relates to a unitized-wall modular façade (2) of a building (1), which is comprised by a number of prefab panels (10) assembled together, which will explained below.
  • Figure 1 shows the building (1), the modular façade (2) and the prefab panels (10) which are connected to floor slabs (5) of each floor (4) by means of brackets (31) and connecting plates (34).

Further optionally, there is at least one third horizontal profile (not shown) between the first (12) and the second (13) horizontal profile(s). If both third vertical profile(s) (17) and third horizontal profile(s) are present, throughgoing third vertical profile(s) (17) are preferred for statics.
  • outer cladding (19) made of a gypsum panel, also referred to as "plasterboard panel", (such as Glasroc ® X) attached to the profiles (12, 13, 15, 16, 17), by attaching means (20), such as screws, for instance, Placotherm ® Integra screws.
  • the outer cladding (19) is a façade exterior-closing element.
  • Joint sealing elements (22) preferably self-adhesive, may be outwardly attached to at least one of the horizontal profiles (12, 13) and / or at least one of the vertical profiles (15, 16) for guaranteeing correct function of each prefab panel (10) in combination with the rest of the façade (2).
  • the joint sealing element(s) (22) are located in the whole perimeter of the prefab panel (10) after retiring a protective peel-off sheet (not shown), for providing airtightness and watertightness to the solution. Also, it serves to attach each prefab panel (10) to adjacent prefab panels (10) in the vertical and horizontal sides during installation.
  • the joint sealing elements (22) may preferably be made of a foam, such as Norseal ® .
  • the outer profiles i.e., the first (12) and second (13) horizontal profile, and the first (15) and second (16) vertical profile, overlap the cladding (19), there is one and only one first (12) and second (13) horizontal profile, and also there is one and only one first (15) and second (16) vertical profile.
  • a thermal insulator (not shown) made of mineral wool, for instance, is housed in the frame structure (11), behind the outer cladding (19).
  • the first (12) and second (13) vertical profiles, as well as the first (15) and second (16) horizontal profiles, have a matching shiplap (21) design.
  • the shiplap (21) design of the horizontal profiles (12, 13) is designed for clamping fit of the outer cladding (19).
  • the third horizontal and/or vertical (17) profile(s) may be C standard façade profiles centrally located for increasing the plasterboard resistance and improve stability of the prefab panel (10).
  • their profile width is selected among: 50 mm, 75 mm and 100 mm.
  • Brackets (31) are attachable to the vertical profiles (15, 16, 17), for connecting the prefab panel (10) to a floor slab (5) of the building (1) by means of a connecting plate (34) made of metal which is interspersed between the brackets (31) and the floor slab (5), for supporting the prefab panels (10), in particular, the frame structure (11) thereof, and the façade loads.
