DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a construction board, in particular to a longitudinal laminate board of mineral wool, which is appropriate as a core of a sandwich element having a surface layer e.g. of sheet metal on each side. The laminate board consists of adjacently disposed rods, whose fibre plane forms essentially a right angle to that of the laminate board and at least a number of the rods being shorter than the laminate board.
The invention also relates to a method for manufacturing the laminate board, in which rods are cut out from a mineral wool sheet with a length different from the one of the laminate board, are rotated 90.degree. about their longitudinal axes and are assembled into a laminate board.
BACKGROUND OF THE INVENTION
Laminate boards of this type are prior known and have been implemented for instance in naval industry as insulating walls of various spaces.
Sandwich elements of mineral wool have been utilized to some extent in naval industry. So far long supporting elements have not however, been available, neither as ceiling, floor nor wall elements.
Finished sandwich elements of mineral wool with the fibres oriented perpendicularly to the surface plane of the element would, owing to its resistance properties, be usable as supporting roof, floor and wall elements and would thus simplify building operations greatly.
SUMMARY OF THE INVENTION
The object of the present invention is thus to provide longitudinal laminate boards usable as a core of supporting sandwich elements for roof, floor and wall constructions as well as a method for manufacturing such laminate boards.
According to the invention, this object has been achieved by matching the opposite end surfaces of two aligned rods and connecting them and further by providing a method in which the rods are assembled with end surfaces facing into longitudinal rods, from which rods equalling the length of the laminate boards are cut off and connected laterally to form the laminate board.
Thus, the laminate board of the invention is longitudinal, it is made of binder fixed mineral wool and is appropriate for use as a core of a sandwich element, whereby it is combined with surface layers, of sheet metal for instance, on each side. The laminate core is formed of adjacent rods whose fibre plane is perpendicularly oriented to the plane of the laminate board and at least a number of the rods being shorter than the laminate board. According to the invention, the opposite end surfaces of two aligned rods are matched and interconnected. At least some of the rods being shorter than the laminate board, such rods consist of jointed rods. In this case it is essential that the end surface be connected so that the resistance of the laminate board is not deteriorated.
According to a preferred embodiment of the laminate board, the end surfaces are glued against each other. According to another embodiment, the end surfaces are pressed against each other forming border layer in which fibres from both surfaces are in contact with each other, engaging into each other.
According to a preferred embodiment, the matching end surfaces can be inclined so as not to form a right angle to the longitudinal axis of the rods. According to a further developed embodiment, the end surfaces form a right angle to the plane of the laminate board, being simultaneously and preferably tilted towards the longitudinal axis of the rods.
According to a further embodiment of the laminate board, the end surfaces form a so-called finger joint, the fingers forming projections and grooves parallel to the plane of the laminate board.
A laminate board according to the invention is produced in a known manner by cutting rods in a mineral wool board having a length different from the one of the laminate board, are rotated 90.degree. about their longitudinal axes and are assembled to form a laminate board.
According to the invention, the rods are connected with end surfaces facing each other into longitudinal rods, in which rods having the length of the laminate board are
