摘要： PROBLEM TO BE SOLVED: To collect by adsorbing toxic material generated from concrete or an interior finish material containing an adhesive or the like which is used for a building so as not to dissipate in a living space. SOLUTION: A surface of a bamboo material 1 fabricated in a plane shape is exposed to a combustion gas, and a carbonized film 2 is formed on a surface to a depth of about 10% of a thickness of the bamboo material, which is used. Otherewise, either of carbon powder obtained by activation treatment by carbonizing the bamboo material 1 as a raw material, or carbon powder obtained by carbonizing at high temperature and quench treatment, is laminated as a film 3 on a surface of the carbonized film 2. Such the material is used.

摘要： PURPOSE: To expand a round bamboo from a circular shape into a platelike shape by providing a constant length for a round bamboo material having an irregular cross section, an outer diameter which contracts gradually and a warp, smoothing its inside and outside faces in that state, and pressing it from the inside and outside faces by utilizing grooves arranged in the longitudinal direction. CONSTITUTION: An expanding device 72 consists of a leading equipment 73, a heating equipment 74, a correcting equipment 75, and an expanding equipments in a plurality of zones 76, 77, and 78. The leading equipment 73 has a conveyor 81. The heating equipment 74 consists of upper and lower heaters 83 and 84. The upper heater 83 has an up-and-down move means. In the correcting equipment 75 and the expanding equipments in the zones 76, 77, 78, a process starting from a pair of drumlike pressure roller 91 and support roller 101 up to a pair of parallel pressure roller 91U and support roller 101U is divided so as to arrange a large number of pair rollers having radius of curvature equivalent to an expanding condition, and grooves are formed on the surfaces of the pair rollers in some parts so as to expand a round bamboo material 1A.

摘要： PURPOSE:To obtain a flat plate having a width that is approximately twice as large as that in a prior art by a flat plate production method wherein inner and outer nodes are removed without cutting a material bamboo into halves, and this is developed right and left from one longitudinal groove. CONSTITUTION:In a method for producing a flat plate out of a bamboo material, a substantially uniform material is obtained by cutting an unavailable part off a natural bamboo; this material bamboo is firmly fixed by a chucking device without cutting it into halves; outer nodes are removed by a node cutter 20 of an external device 8; inner nodes are removed by an inner node cutter; a slit longitudinal groove extending in a longitudinal direction is formed by rotating a rotational saw blade at a fixed position with the travel of the bamboo; the bamboo is heated and fed by a feed guide roll; the right and left edges of the single groove are gradually stretched under pressure by a press roller; and the bamboo is finally made into a flat plate. After that, the obtained flat bamboo plate is dried, and the flat surface thereof is processed.
