Definitions

  • the invention relates to a construction board, in. particular to a longitudinal laminate board of binder fixed mineral wool, which is suitable as a core of a sandwich element having a surface layer, e.g. of sheet metal, on each side, consisting of adjacently disposed rods, the longitudinal direction of which coincide with the one of the laminate board and whose fibre plane form a right angle to the plane of the laminate board.
  • a surface layer e.g. of sheet metal
  • Laminate boards of this type are prior known, having been used for instance in shipbuilding industry as insulating walls of various spaces.
  • the sandwich element of mineral wool has been used to some extent within the shipbuilding industry. So far, however, longitudinal elements have not been available, neither as roof or floor elements, nor as wall elements.
  • the idea of rotating cut laminates 90o and of reassembling them in the turned position, thus obtaining a laminate board having fibres oriented perpendicularly to the plane of the board, is prior known.
  • Such a laminate board has excellent resistance properties and is able to transfer shearing forces between its surface planes.
  • the object of this invention is to provide long sandwich elements having a core consisting of fire, noise and heat insulating laminate boards for roof, floor and wall constructions.
  • the facts mentioned about the joint surface of the laminates are pertinent regardless of the joint surface being vertical to the surface layer of the laminate board or its being tilted, the joint surface being greater in the latter case than in the former.
  • the total surface of the joint surfaces must not exceed one third of the cross-sectional surface.
  • a laminate board with 9 laminates whereby the length a of the board may comprise three vertical joint surfaces, none of which is an inclined joint surface, which would result in a total joint surface that is greater than one third of the total cross-sectional surface.
  • a long construction board can be provided, of the size order of 9-10 m, by means of laminates rotated 90o and reassembled, without handling mineral wool mats and cut laminates of the corresponding length.
  • a board is obtained, which used as a core of a sandwich element has the same resistance properties as a board without joints, i.e. in which the weakening influence of the joints has been eliminated.
  • none of the joints is closer to an end of the laminate board than a.
  • maximally one joint is disposed within the range 2a from any end of the board.
  • maximally two joints are disposed within the distance 3a from any end of the board.
  • the distance a indicating the length of the critical area equals L : 2n. Since the support points, among others, have a certain extension, the length a has to be made somewhat longer, and thus the length L is appropriately divided by 1,9n.
  • the distance between joints of two adjacent rows of rods preferably equals at least the thickness of the rods in the laminate board, i.e. the thickness of the laminate board.
  • the rods are connected with a glue joint by applying glue to the end surfaces before connecting and fixing e.g. by drying subsequent to the forming of the laminate board.
  • the glue application is appropriately performed before the phase displacement of the rod flow.
  • the end surfaces of the rode are face milled or prepared so as to match the surfaces well, before a possible glue application.
  • the future lateral surfaces of the rods are face milled or prepared so that the rods will fit tightly to each other.
  • traces are made in the end faces of the rode, parallel to the plane of the laminate board or perpendicular to these, so as to provide a finger joint between the rods.
  • the rods are pressed together during the connecting moment at a pressure exceeding 100 Pa, preferably 500 Pa.
  • the mineral wool mat used as starting material consists of a bin der fixed mineral wool, which may be a rock wool or a glass wool forming essentially plane parallel layers consisting of vitreous fibres more or less in disorder.
  • a bin der fixed mineral wool which may be a rock wool or a glass wool forming essentially plane parallel layers consisting of vitreous fibres more or less in disorder.
  • the parametres a, L and n are used for determining the exact position for cutting off a long rod into a laminate of the laminate board and for phase displacing the long rod with regard to the preceding long rod in the board.
  • the parametres are used for programming a computer for automatic control of the cutting of the long rods.
  • joints 3 are relatively equally di ⁇ tributed over the laminate board and a comparison between the above parametres shows that all the criteria are being fulfilled.
  • the manufacture of the laminate board is carried out by assembling laterally rods cut from a mineral wool mat and rotated in order to form the laminate board.
  • the assembling of the rods that have been cut off and rotated can be accomplished in various manners.
  • the construction board of the invention is usable as supporting wall, floor or roof elements.
  • the board has good fire and heat insulating properties owing to its construction, and it is easy to install.

Abstract

L'invention concerne un panneau stratifié longitudinalement (1) en laine minérale fixée par un liant, qui convient pour former le noyau d'un élément sandwich ayant des surfaces externes, constituées par exemple, de minces plaques métalliques. Le panneau stratifié est constitué de barres disposées de façon adjacente et en direction de la longueur (2) dont le plan des fibres présente un angle droit par rapport au plan du panneau stratifié. Les barres sont plus courtes que ledit panneau et sont jointes bout à bout. Les liaisons sont réparties dans le panneau stratifié de manière à éliminer leur effet d'affaiblissement sur la résistance du panneau. Les surfaces totales de liaison des stratifiés constituent, dans une intervalle (a) du panneau, où (a) dépend de la longueur du panneau et du nombre de stratifiés contenu sur la longueur, au maximum un tiers de la section du panneau. Quant aux zones de longueur (a) près des faces d'extrémité et près des lignes de support des panneaux à champs multiples, moins de liaisons sont nécessaires par rapport aux zones interposées.
