PROBLEM TO BE SOLVED: To provide a floor construction in which a gap or a cup is hardly formed between a tongue part and a groove part by firmly bonding and fixing the mutually fitted tongue part and the groove part via an adhesive agent when the floor is constructed by joining the floor plate which is to be fitted next, to the floor plate which is laid earlier, by the tongue part and the groove part. SOLUTION: An adhesive agent 5 is heaped on a lower face of a front end part of the tongue part 4 of the floor plate 2B which is to be laid. After that, the tongue part 4 of the floor plate 2B is arranged to face the groove part 3 of the floor plate which is placed earlier, and then part of the adhesive agent 5 is rubbed backward on a floor underlayer 1 near the groove part 3. At the same time, the remaining adhesive agent 5 is transferred to and placed over the front end face to the upper face of the male part 4 by the rubbing action. Next, the remaining adhesive agent is spread by fitting the male part 4 into the groove part 3, so that an adhesive agent layer may be formed where the male part and the female part are substantially fully bonded together.

PROBLEM TO BE SOLVED: To make a laminated composite wooden material usable equally as usual plywood and LVL by arranging veneer made of acacia-mangium which is reduced in dimensional change and strong enough in the material excluding surface and back layers and using good-looking, good-quality plates in the surface and back layers. SOLUTION: In the laminated composite wooden material, a plurality of plates are laminated/integrated. Low-quality veneer of acacia-mangium is used in the material excluding the surface and back layers 11, By using the good-looking, good-quality plates in the surface and back layers, the material can be used appropriately as usual plywood or LVL. Alternatively, by using veneer of eucalyptus in the surface and back layers 11 and a longitudinal core 12 and using the veneer of acacia-mangium in an additional core 12, the specific gravity of the material can be reduced without lowering the strength of good-looking, strong, heavy (specific gravity: at least 0.7) eucalyptus plywood, because the specific gravity of acacia-mangium is as low as 0.5-0.6.
