Definitions

  • the invention relates to a building structure, more particularly a structure involving prefabricated structural insulated panels (SIPs), panel systems with joining elements such as connectors to support an insulation barrier along the wall, with fastening elements, to reduce thermal changes between the exterior and interior of the building.
  • the connectors serve as slab reinforcement.
  • the blocks assembled from such elements can be used for floors, walls, slabs and roofs in residential, commercial or individual buildings. With uniform load distribution throughout the building.
  • SIP structural insulated panels
  • SIP panel houses are assembled quickly and qualitatively on site, using specially prefabricated panels. Timber beams or timber I-joists are used for assembling. https://ecohouse.eu/technologija/
  • Panels with frame structures are glued with specific adhesive and/or secured with wood screws.
  • the house structure becomes homogeneous, moisture-resistant, and weather-resistant (to rain, cold, snow and heat).
  • Insulated building construction comprising: first and second walls; first means for joining said first and second walls; one of said first and second walls including first and second panels each having: an interior skin; an exterior skin; and an insulating core fastened between said interior and exterior skins, said interior skin, said exterior skin and said core all having vertical edges, the vertical edges of said interior skin and said exterior skin extending in a horizontal direction beyond the vertical edges of said core at one end to form a first groove at such end of each of said first and second panels; and means for connecting said first and second panels together.
  • the above joining member consists of three parts: exterior and interior fastening elements, and insulated compacted polystyrene in-between.
  • This invention relates to a kit of composite and wooden frame elements for the construction of thermally passive buildings. Light insulating components are provided therein. Assembly can be easily carried out by a single installer, and excellent thermal and air insulation can be obtained.
  • the disadvantage of the above invention is that it is necessary to build the frame of the house and then attach the insulation components to it.
  • Such a building requires a pre-designed frame and specialized tools as well as respective knowledge for construction. It also involves additional elements that increase construction costs.
  • foundation loads are concentrated at certain areas, uneven load distribution, and the foundation is necessary.
  • This invention is in the field of a self-supporting modular system for a building, in particular for structural elements thereof, a building comprising said modular system, such an office building, a utility building, and a house, and a kit of parts comprising at least one element of said modular building system.
  • a new "Optimal Wall” construction system consisting of three main elements is proposed to reduce the construction costs of single or double storey residential, public, or industrial buildings of different architecture without compromising energy efficiency, durability, and structural strength. These elements are universal; therefore, there is no need for a specific project design - availability of continuous manufacturing at the workshop and delivery to the warehouse.
  • the above elements are structural insulated panels (SIP) and insulated connectors and parts thereof, which are adapted by cutting, dissecting, or joining.
  • a tight frame-shell structure is obtained by securing the above elements and their parts together using nails, screws, or wood screws, and sealing the joining points with mounting foam. Thermal bridges are prevented due to insulated connectors applied.
  • the shell-type structure ensures the spatial stability of the building, making it tight, light, and thermally efficient (A++, passive). There are no concentrated loads, and no need for traditional foundations. It is just necessary for construction to prepare the site of compacted soil/gravel and arrange engineering network piping.
  • the present invention involving the usage of three elements, their application by cutting or dissecting, and interconnection with each other, allows obtaining the preferred technical result:
  • fibrolite (GreenBoard) boards which consist of: wood wool - 60%, portland cement (ordinary cement) - 39%, mineralizer (Sodium metasilicate - molten glass) - 1%; insulating layer - a material where layer thickness, depending on the value of the thermal conductivity coefficient, is selected according to the desired level of energy efficiency - the most acceptable is polystyrene foam EPS 100N with thermal conductivity coefficient ⁇ D: 0,03 m 2 K/W and compressive strength ⁇ 100 kPa, bending strength ⁇ 150 kPa or polyisocyanurate/polyurethane foam)(PIR) with thermal conductivity coefficient ⁇ D: 0,022 m 2 K/W, and the like, these materials allow reaching the energy efficiency class A

  • the above three elements, where needed, are applied by cutting or dissecting, and joined to each other, and secured with nails, screws or wood screws, then sealed with mounting foam and thereby forming a tight frame shell structure. Thermal bridges are prevented due to insulated connectors.

  • the provided embodiment ( Fig. 4 ) for building wall angle construction comprises: joining two SIPs cut at the required angle, without cutting off the part of external surface (4) of the SIP towards the insulation part (if right 90° angle is joined, the cut is done at 45° angle in respect of SIP external and internal surfaces (4, 5)), at the corner through a timber beam and gluing the cut insulation parts (6') of SIP to each other.

  • Optimal dimensions of three elements of the system SIP length 3 m, which corresponds to the traditional height of the room, and width of 0,6 m - optimal step of frame struts, recess between SIP external and internal surfaces (4, 5) with smaller insulating layer (6) therebetween for placing the joining elements - connectors (2, 3, 3', 3", 3′′′) of 0,05 m, uniform along the perimeter, and the width of connectors (2, 3, 3', 3", 3′′′) is 0,1 m, and thickness corresponds to insulating layer (6) thickness; optimal insulating layer - 0,2-0,3 m (based on desired level of energy efficiency can be thinner/thicker); the element dimensions are interrelated depending on preferred energy efficiency level or optimality of structural connections to be achieved.
  • non-flammable, water-resistant and inert panels are the most suitable for SIP external (4) and internal (5) surface; for insulating layer - material depends on preferred energy efficiency level, i.e thermal conductivity coefficient value, to be achieved.
