Estimating the term…
The collected lumber of the present invention is formed by heating and softening a plurality of woods, applying adhesive on the woods, pressing and compressing the wood with adhesive thereon to mold the integral body in a prescribed shape, and by fixation treating the integral body using a heating device. The method for manufacturing collected lumber of this invention comprises the first process for softening woods by heat treating a plurality of woods, the second process for applying adhesive on the softened woods, the third process for forming integral body by pressing and compressing the woods applied with the adhesive to mold in a prescribed shape, and the fourth process for fixation treating the integral body using a heating device. By collecting and fixing a plurality of woods comprising thinned-out woods which is not worth using, the wood products which exhibits various excellent grain pattern and is used for wide range of building materials are manufactured, and the enhanced productivity is attained by shortening of curing time of collected wood to realize low cost collected lumber and process for manufacturing the collected lumber.
A collected lumber produced by heating a plurality of woods to soften said woods, compressing said softened woods in the presence therebetween of a reinforcing member for interconnection of said woods and an adhesive to thereby form said woods into a predetermined shape, and subjecting the formed wood body to a fixation treatment using a heating device.
A process for producing a collected lumber, comprising:
A wood building material comprising a piece of wood, wherein a straight grain in a compressively molded shape is exposed on at least one face of said piece of wood.
A process for producing a wood building material, comprising:
A collected lumber comprising a collected body formed from a plurality of woods with an adhesive between said woods, said collected body having annual rings of said woods left in variously molded-state on its end faces.
A collected lumber comprising a collected body formed from a plurality of conifer woods with an adhesive between said woods, said collected body having annular rings of said woods left in complicatedly molded state at its ends, and said ends having a hardness of 4.6 to 9.0 kgf/mm.sup.2, as measured according to JIS Z 2117.
A collected lumber comprising a collected body formed from a plurality of bamboos with an adhesive therebetween, said collected lumber at its ends having a hardness of 5.2 to 8.5 kgf/mm.sup.2, as measured according to JIS Z 2117.
A collected lumber comprising a collected body formed from a plurality of conifer woods and bamboos with an adhesive therebetween, said collected body having annual rings of said conifer woods left in complicatedly molded state at its ends, and said bamboos being incorporated between said conifer woods.
A collected lumber comprising a collected body formed from a plurality of woods with an adhesive therebetween, said collected body having annular rings of said woods left in complicatedly molded state at its ends, and said collected body having a depth of abrasion of 25 to 170 .mu.m after 500 revolutions, as measured for side faces having a longitudinal straight grain or cross grain of wood according to the Abrasion Test A of JAS.
A collected lumber comprising a collected body formed from a plurality of bamboos with an adhesive therebetween, said collected body having a depth of abrasion of 30 to 145 .mu.m after 500 revolutions, as measured for its side face having a longitudinal fiber pattern of bamboo according to the Abrasion Test A of JAS.
A vehicle-carried type apparatus for manufacturing a collected lumber, comprising on a self-running vehicle one or more devices for heating a plurality of woods to soften said woods, compressing said softened woods with an adhesive therebetween to form a collected body, and subjecting said collected body to a fixation treatment.
