Definitions

  • the present invention relates to aigned building element for the construction of floor structures and/or walls and consisting of wood or other fibrous material with members connecting inner and outer sides positioned at a mutual distance, the connecting members formed from snapped crossbar-forming lamellae distributed essentially along the whole surface range of the building element, extending at an inclination and/or curved into zigzag patterns and distributed along said formed building element and forming paired channels therein.
  • Plateformed building elements used in floor structures and wall systems in buildings are manufactured manually at the building site or prefabricated in a factory. Thereby, pairs of plates are separated at a mutual distance by crossbars.
  • Previously known building elements of said kind consist of lamellae, perpendicular to the surface layer of the building element, forming square or rectangular cells.
  • SE 3384704 and DE 1941368 disclose previously known building elements exhibiting stiffeners in the form of connections formed from relieved lamellae extending in folds or waves.
  • trusses Building elements with trusses are also known wherein said trusses are formed from inclined plates or metal rods.
  • FR 2 793 827 Al discloses trusses composed of angulated plates, but this concerns only a beam thus formed and not wholeaded building elements.
  • WO 99/18304 , EP 0 282 424 A1 and US 4, 475, 328 A disclose trusses forming parallel spaced beams from zigzag-shaped spacing members. The construction of acquiredd elements then takes place manually with a multitude of such beams, which, apart from the fact that the building element acquires limited strength, also may be time-consuming and labor-intensive.
  • any snapped building element comprising inclining and/or curved channel-forming lamellae attached to lateral crossbars through nails or screws whereby the anchoring joints are formed from U-shaped receptacles to which the crossbars can be joined.
  • Known embodiments comprise building elements formed from plates on opposite sides of inclined or curved channel-forming lamellae; and which lamellae and plates are joined together by gluing.
  • the purpose of the present invention is therefore among other things to achieve an improved building element of the initially mentioned kind that allows reduction of the total cost for more efficient manufacturing in a factory as well as better utilization of the supporting capacity of the material, furthermore giving the building element a low tare weight.
  • the advantage in using beams rather than plates on at least one side of the building element is that the building element is formed essentially only from the centrally situated lamellae arranged to extend at an angle with respect to each other and to be able, in connected mode, to receive essentially the total load of said building element.
  • connection of the building element to lateral beams takes place through U-shaped angulated anchoring joints comprising pairs of U-shaped receptacles for angulated lamellae and for connection to angulated beams as shown, for example, in Fig. 6 .
  • the building element as defined in the new claim 1 cannot be considered obvious to a person skilled in the are based on what has been shown to be previously known through the two cited novelty referrals SE 384,708 and DE 1941368 .
  • the present wall and floor structure system has a technical level and thereby the right economical qualities. Through new products with new thinking, such as this building-frame intended to be supplemented by other working methods, wood will become more competitive and its value will be increased with great potential. According to calculation, the floor structure system has load bearing capacity at rupture limit conditions and dynamic stiffness towards oscillations at usage limit conditions, in both cases a good measure of overcapacity.
  • Inclining the beams and joining them at the upper and lower edges opens up great opportunity in the future for building structures of wood.
  • the system demonstrates the enormous strength of wood in a co-operating cellular system.
  • the manufacturing of the building elements is to be performed as standardized as possible, with a width of 1,20 m or 2,40 m, but the length may be varied due to the manufacturing method.
  • the building elements can also be spliced in their longitudinal direction.
  • the proposed building element for this purpose is characterized primarily in that the lamellae are mounted, for instance, at an inclined angle in the form of one or more sine curves absorbing the tensile and compressive forces with a zero in the center of the building elements. Thereby, the forces will co-operate with the outer shell in an efficient manner.
  • the core of the floor structure element or wall element is designed as a trigonometric shape so that the load bearing capacity increases exceptionally in co-operation with the design of the outer shell.
  • the forces co-operate in the way of a sine curve. This is kept together through crossbars, boards or plate material, perpendicularly along the upper and lower edges. At the breaking points, the material is fixed together. It forms long triangular-shaped channels along the crossbars or beams along the lower as well as the upper edges.
  • the characteristics of the wall and floor structure fulfill many demands.
  • the strength of the elements in all directions is unique.
  • a good tightness is obtained due to the connection of the crossbars and beams.
  • the crossbars are now inclined or curving towards each other with-connection in the short sides of the crossbars against the-outer and inner edges of the wall. In this way a zigzag pattern is achieved in the wall system, endowing the wall with many good qualities such as the load bearing capacity, soundproofness, fireproofness, tightness, and very good stability in all directions.
  • the beams are positioned inclining towards each other but are connected to each other at the upper end of the beams. This applies also for the lower ends.
  • the connection can be through specially designed metal shoes. Plates, crossbars or boards functioning to keep the building element together may also be used.
  • the present invention relates to a cellularly divided trigonometric building element in which the cells are kept together along the upper and lower edges through plate material or similar.
  • the invention concerns such a building element of the kind comprising a multitude of cells of similar appearance, next to and mounted towards each other through gluing or similar.
  • the inclined lamellae form a number of identical cells in the building element
  • the pattern of the various cells form longitudinal channels in the longitudinal direction of the building element.
  • Each of the different cellular--systems has different properties, but it is the most cost efficient cellular system in relation to the most desirable properties that will decide the manufacturing system, which is to be as industrialized as possible.
  • the material in the upper and lower edges of the building element may be different, for example, plate material, boards or crossbars made of wood or other fibrous material mounted with glue or in similar ways.
  • Drawing irons may also be used at the lower edge of the elements in order to increase the load bearing capacity of the building elements.These drawing irons may be used to pull the building elements together into large continuous floor structures during assembly at the construction site.
  • Prefabricated building element of said kind are utilized above all as load-bearing floor structures and roof elements in the building of one-family houses, apartment buildings, economy buildings, and industrial premises etc. They can, however, also be utilized for other purposes, for instance, as bearing wall elements.
