Definitions
- the present invention concerns a floor element and a method for manufacture of a floor element.
- a floor construe .ton of a cell type in which the main structure of the element consists of a cell system, onto which an upper plywood board and a lower metal sheet have been fixed by gluing. Onto the plywood board, a separate layer of reinforced plastic has been spread, for example fibreglass mix that contains quartz sand or a polyurethane coating which preferably also contains quartz sand.
- the cell structure is manufactured in a jig out of separate cardboard tubes.
- the length of the cardboard tubes is about 1 metre, and said tubes are fitted into the space defined by the jig plates after treat- ment of the faces of the cardboard tubes with an adhesive.
- the glue-joined structure is removed from the jig, and the cell system is cut by means of a band saw into sheets of a length of about 71 mm.
- the cell tubes are fitted so that their longitudinal axes are perpendicular to the top and bottom planes of the floor element. In such a case, the overall rigidity of the construction board against bending is good.
- a plywood board is placed on the bottom, the cell system is placed on the plywood board.
- the plywood that is used is preferably birch plywood.
- an adhesive is applied onto the plywood board, and, similarly, at the stage of assembly of the construction, the upper metal sheet is provided with a layer of adhesive.
- the whole unified structural unit is placed in a press, and compression is applied while the adhesive is drying. After the adhesive agent has dried, the structure is removed from the press, and the plywood is subjected to a surface treatment so that the plywood receives a fibreglass-mix coating, which mix preferably contains quartz sand, or a polyurethane coating, which preferably also contains quartz sand.
- the floor element in accordance with the invention is mainly characterized in that it comprises a bottom sheet and a top board and, between them, a cell structure which consists of tube portions that have been glued together and whose central axes (X axes) are perpendicular to the top board and to the bottom sheet.
- the method in accordance with the invention for manufacture of a floor element is mainly characterized in that, in the method, the cell system is formed out of a tube structure, in which connection the tubes that have been sawed to a specified measure are fitted into a jig after adhesive treatment and in which connection, after the tubes have been joined together in the adhesive treatment inside the jig, the set of tubes is removed from the jig, and the set of tubes is sawn to cell board structures of specified dimensions, and that, in the method, the cell board thus formed is fitted between a top board and a bottom sheet, and side boards are fitted into the structure also between the top board and the bottom sheet, and the unit thus formed is subjected to compression, after which, upon drying of the adhesive, the floor element is removed from the press.
- Figures 1A...1E illustrate the manufacture of a floor element in accordance with the present invention step by step.
- Figure 2 is an axonometric view of a floor element in accordance with the invention.
- Figure 3 shows a floor element in accordance with the invention as a sectional illustration in part.
- Fig. 1A shows the stacking of tubes 10a j ,10a 2 ... of a length of about 1 metre into the space D defined in the interior of the jig J.
- the jig J has been formed out of plate elements J ⁇ ,J 2 »J3 > ⁇ 4 and J 5 .
- the tubes 10a j ,10a 2 are preferably made of cardboard. They can also be made of plastic.
- the cardboard tubes 10a ⁇ ,10a 2 are stacked into the space D in the interior of the jig J. Before stacking, the faces of the tubes have been treated with an adhesive agent.
- the set P of tubes is removed from the jig J interior.
- sheets of a length of about 71 mm are cut off out of the glue-joined set P of tubes by means of a band saw H.
- Fig. 1C shows a cut-off cell board structure.
- the cut-off cell board structure 100 is placed on a top board, preferably a plywood board 12.
- a top board preferably a plywood board 12.
- the inner face of the top board 12, preferably a plywood board, is treated with an adhesive F.
- the bottom sheet 13 which is preferably a metal sheet, is also treated with an adhesive agent in respect of the face that is placed against the cell board 100.
- the side boards 14a 1 , 14a 2 ,14a 3 and 14a 4 are also placed in connection with the construction so that they form the side structures of the floor element.
- the side boards 14a 1 ,14a 2 ,14a 3 and 14a 4 are placed between the top board 12 and the bottom sheet 13.
- the side walls 14a ] ,14a 2 , 14a 3 , 14a are also made of plywood, preferably birch plywood.
- the unit thus formed is placed under compression.
- the press is denoted with the reference numeral 15.
- the press 15 can be a vacuum press or any other press device whatsoever.
- the top board 12 of plywood of the floor element is coated with fibreglass or polyurethane, in which connection a layer of fibreglass or polyurethane is applied onto the top board 12.
- the fibreglass or polyurethane layer 16 preferably contains quartz sand.
- Fig. 2 shows a finished floor element in accordance with the invention.
- Fig. 3 illustrates the floor element of Fig. 2 partly in section.
- the cell system 100 is fitted in such a way between the top board 12 and the bottom sheet 13 that the longitudinal axes (X axes) of the tubes 10a ⁇ ,10a 2 ... in the cell system 100 are placed perpendicu ⁇ larly to the planes T ⁇ ,T 2 of the top board 12 and the bottom sheet 13.
