发明内容 本实用新型的目的是：采用毛竹片或毛竹丝拼接胶压成集成材作表板，充分利用速生小径材作为芯材，经搭配组合，制成具有高性能、低成本的竹木复合新型结构材。SUMMARY OF THE INVENTION The purpose of this utility model is to use moso bamboo slices or moso bamboo silk splicing glue to form glulam as the surface board, make full use of fast-growing small-diameter wood as the core material, and make a bamboo-wood composite with high performance and low cost through matching and combination. New structural materials.
本实用新型的一种竹木复合新型结构材由多层板材涂胶热压而成，其特征在于表层、中层和底层为竹材，两竹材间夹着的芯层为木质芯材。竹木复合新型结构材可以制成竹木复合板材，也可以制成竹木复合方材，其表层、中层和底层一般采用竹质集成材，即由毛竹片或毛竹丝拼接胶压而成。两竹材间夹着木质芯材，如层积材、刨花板、纤维板；一般采用木质层积材，即由木质单板层叠胶合而成。木质芯材一般以杉木间伐材为原料。A new bamboo-wood composite structural material of the utility model is formed by coating and hot-pressing multi-layer boards, and is characterized in that the surface layer, the middle layer and the bottom layer are bamboo materials, and the core layer sandwiched between the two bamboo materials is a wooden core material. Bamboo-wood composite new-type structural materials can be made into bamboo-wood composite boards or bamboo-wood composite squares. The surface, middle and bottom layers are generally made of bamboo laminated materials, that is, moso bamboo sheets or moso bamboo silk are spliced and glued. Wooden core materials are sandwiched between two bamboo materials, such as laminated timber, particleboard, and fiberboard; generally, wooden laminated timber is used, that is, laminated and glued wooden veneers. The woody core material is generally made of Chinese fir thinning wood.
本实用新型一种竹木复合新型结构材为多层结构，采用集成-层积结构对称均衡组合。例如，当竹木复合新型结构材为七层组合时，具有表层、底层和2个中层、3个芯层；当竹木复合新型结构材为五层组合时，具有表层、底层和1个中层、2个芯层；当竹木复合新型结构材为三层组合时，具有表层、底层和0个中层、1个芯层，即结构上没有中层。更多层组合的竹木复合新型结构材依此类推。竹木复合新型结构材一般由3～11层的竹质集成材和木质层积材组合而成。The utility model discloses a bamboo-wood composite novel structural material with a multi-layer structure, which adopts a symmetrical and balanced combination of an integrated-layered structure. For example, when the new bamboo-wood composite structural material is a combination of seven layers, it has a surface layer, a bottom layer, 2 middle layers, and 3 core layers; , 2 core layers; when the new bamboo-wood composite structural material is a three-layer combination, it has a surface layer, a bottom layer, 0 middle layers, and 1 core layer, that is, there is no middle layer in the structure. Bamboo-wood composite new structural materials with more layers combined and so on. Bamboo-wood composite new-type structural timber is generally composed of 3 to 11 layers of bamboo laminated timber and wood-laminated timber.
本实用新型的一种竹木复合新型结构材的优点：采用集成-层积结构对称均衡组合，其表层采用毛竹片沿纤维平行的宽度方向拼胶或长度方向拼接胶压成集成材，具有物理力学上高强度的特点。根据复合材料的力学理论，板材在受到垂直板面的外加载荷作用时，弯曲应力主要由靠近表层的材料承担，芯层主要承受剪应力作用，强度大的材料距离板材厚度中心愈大可承受弯曲应力愈大。竹材处于表层(5层或5层以上结构增设中层)，具有硬度大强度好的特点；木质芯材处于次中层，具有胶合力强，可降低密度的优点。The advantages of a new type of bamboo-wood composite structural material of the utility model: it adopts a symmetrical and balanced combination of integration-laminated structure, and its surface layer is made of moso bamboo slices along the width direction parallel to the fibers or glued together in the length direction to form a laminated material, which has physical Mechanically high-strength characteristics. According to the mechanical theory of composite materials, when the plate is subjected to an applied load vertical to the plate surface, the bending stress is mainly borne by the material close to the surface layer, and the core layer mainly bears the shear stress. The greater the stress. Bamboo is in the surface layer (the middle layer is added to the structure with 5 or more layers), which has the characteristics of high hardness and good strength; the wooden core material is in the second middle layer, which has the advantages of strong adhesive force and can reduce the density.
另外，木质芯材与中层材料一般以杉木间伐材和毛竹丝为原料，具有价廉，提高综合利用率，降低成本的优势。据统计各种竹材人造板的竹材利用率为：竹材层压板50％左右；竹席、竹帘胶合板45％～50％；竹材胶合板35％～40％；竹地板生产中竹材的直接利用率仅为20％～25％。本实用新型的竹木复合新型结构材可将竹材的利用率提高到80％以上，还利用较廉价的杉木间伐材为芯材，可降低原料成本20％以上，为我国竹材工业的发展带来了机遇，“以竹代木”、“以竹胜木”为缓解我国木材供应紧张局面发挥了极积的作用。In addition, the woody core material and middle layer material are generally made of fir thinning wood and moso bamboo shreds, which have the advantages of low price, improved comprehensive utilization rate, and reduced cost. According to statistics, the bamboo utilization rate of various bamboo wood-based panels is: about 50% for bamboo laminates; 45% to 50% for bamboo mats and bamboo curtain plywood; 35% to 40% for bamboo plywood; 20% to 25%. The bamboo-wood composite new structural material of the utility model can increase the utilization rate of bamboo to more than 80%, and also use cheaper Chinese fir thinning material as the core material, which can reduce the cost of raw materials by more than 20%, which brings great benefits to the development of my country's bamboo industry. Given the opportunity, "replacing wood with bamboo" and "surviving wood with bamboo" have played an active role in alleviating the tense situation of timber supply in my country.
