Description
技术领域Technical Field
本发明涉及土木工程竹木技术领域,更具体的说是涉及一种内置竖向钢板增强重组竹梁及其制备方法。The invention relates to the technical field of bamboo and wood in civil engineering, and more particularly to a reconstructed bamboo beam reinforced with a built-in vertical steel plate and a preparation method thereof.
背景技术Background Art
竹材与木材相比具有绿色天然、强度高、韧性好、生长周期短等优点,被结构工程师们誉为“植物钢筋”,近年来出现了各种结构工程竹制品,如重组竹和胶合竹等。重组竹是一种将竹材重新组织并加以强化成型的竹质新材料,即将竹材加工成长条状竹篾、竹丝或碾碎成竹丝束,经干燥后浸胶,再干燥到要求含水率,然后铺放在模具中,经高温高压热固化而成的型材。与天然竹材相比,重组竹具有绿色环保、材料利用率高、强度大、缺陷少、可加工成各种形状等优点,便于工程应用,在土木工程等领域具有非常光明的前景。Compared with wood, bamboo has the advantages of being green, natural, strong, tough, and having a short growth cycle. It is praised by structural engineers as "plant steel bars". In recent years, various structural engineering bamboo products have emerged, such as reconstructed bamboo and glued bamboo. Reconstructed bamboo is a new bamboo material that is reorganized and reinforced. That is, the bamboo is processed into long strips of bamboo strips, bamboo fibers, or crushed into bamboo fiber bundles, which are then dried and impregnated with glue, and then dried to the required moisture content. Then, they are laid in a mold and cured at high temperature and high pressure to form a profile. Compared with natural bamboo, reconstructed bamboo has the advantages of being green and environmentally friendly, having a high material utilization rate, high strength, few defects, and can be processed into various shapes. It is easy to apply in engineering and has a very bright future in the fields of civil engineering.
在现有的重组竹梁中,虽然重组竹继承了天然竹材绿色天然、韧性好的特点,并且成功克服了其力学性能离散性较大、易虫蛀、耐久性较差等缺点,但作为结构中的主要受弯构件,重组竹梁的弹性模量偏低,在进行重组竹梁设计时,常由刚度控制,重组竹的强度没有得到充分发挥。因此,在进行重组竹梁的承载力验算时,为满足其刚度要求,往往需要更大的截面尺寸,这就造成了材料浪费,同时也增大了结构本身的重量。In the existing reconstructed bamboo beams, although reconstructed bamboo inherits the characteristics of natural bamboo, which is green and has good toughness, and has successfully overcome its shortcomings such as large discreteness of mechanical properties, easy to be eaten by insects, and poor durability, as the main bending member in the structure, the elastic modulus of reconstructed bamboo beams is low. When designing reconstructed bamboo beams, they are often controlled by stiffness, and the strength of reconstructed bamboo is not fully utilized. Therefore, when checking the bearing capacity of reconstructed bamboo beams, in order to meet its stiffness requirements, a larger cross-sectional size is often required, which causes material waste and increases the weight of the structure itself.
因此,如何提供一种既满足强度要求,又满足刚度要求的重组竹梁是本领域技术人员亟需解决的问题。Therefore, how to provide a reconstructed bamboo beam that meets both strength requirements and stiffness requirements is a problem that technical personnel in this field urgently need to solve.

在现有的重组竹梁中,虽然重组竹继承了天然竹材绿色天然、韧性好的特点,并且成功克服了其力学性能离散性较大、易虫蛀、耐久性较差等缺点,但作为结构中的主要受弯构件,重组竹梁的弹性模量偏低,在进行重组竹梁设计时,常由刚度控制,重组竹的强度没有得到充分发挥。因此,在进行重组竹梁的承载力验算时,为满足其刚度要求,往往需要更大的截面尺寸,这就造成了材料浪费,同时也增大了结构本身的重量。In the existing reconstructed bamboo beams, although reconstructed bamboo inherits the characteristics of natural bamboo, which is green and has good toughness, and has successfully overcome its shortcomings such as large discreteness of mechanical properties, easy to be eaten by insects, and poor durability, as the main bending member in the structure, the elastic modulus of reconstructed bamboo beams is low. When designing reconstructed bamboo beams, they are often controlled by stiffness, and the strength of reconstructed bamboo is not fully utilized. Therefore, when checking the bearing capacity of reconstructed bamboo beams, in order to meet its stiffness requirements, a larger cross-sectional size is often required, which causes material waste and increases the weight of the structure itself.
为此,本发明提供了一种内置竖向钢板增强重组竹梁,加工重组竹时,直接将钢板内置于重组竹梁体中,无需开槽也不必二次加工,从而能够有效保证梁的整体性。通过内置竖向钢板增强重组竹梁,相当于增加了重组竹的有效宽度,可有效提高重组竹梁的弹性模量,增大组合梁的截面刚度,达到降低截面尺寸、提高构件承载力、增强重组竹梁受弯性能的良好效果。To this end, the present invention provides a built-in vertical steel plate to strengthen the reconstructed bamboo beam. When processing the reconstructed bamboo, the steel plate is directly built into the reconstructed bamboo beam body without grooving or secondary processing, thereby effectively ensuring the integrity of the beam. By strengthening the reconstructed bamboo beam with the built-in vertical steel plate, it is equivalent to increasing the effective width of the reconstructed bamboo, which can effectively improve the elastic modulus of the reconstructed bamboo beam and increase the cross-sectional rigidity of the composite beam, thereby achieving the good effects of reducing the cross-sectional size, improving the bearing capacity of the component, and enhancing the bending performance of the reconstructed bamboo beam.
在本发明的一个实施例中,参见附图1-3,包括:重组竹梁体100为长方体,高度为150mm,宽度为100mm,长度为6000mm,钢板总宽度为2mm,高度为130mm,长度为5800mm,重组竹梁体100通过多个竹纤维束胶结而成;钢板200竖直嵌设于重组竹梁体100内,并与重组竹梁体100胶结、热压成型。In one embodiment of the present invention, referring to Figures 1-3, it includes: a reconstructed bamboo beam body 100 is a rectangular parallelepiped with a height of 150 mm, a width of 100 mm, and a length of 6000 mm; a steel plate has a total width of 2 mm, a height of 130 mm, and a length of 5800 mm; the reconstructed bamboo beam body 100 is formed by bonding multiple bamboo fiber bundles; a steel plate 200 is vertically embedded in the reconstructed bamboo beam body 100, and is bonded and hot-pressed with the reconstructed bamboo beam body 100.
参见附图4,在本发明的另一个实施例中,包括:重组竹梁体100为长方体,高度为150mm,宽度为100mm,长度为6000mm,钢板总宽度为2mm,高度为130mm,长度为5800mm,重组竹梁体100通过多个竹纤维束胶合而成;钢板200设置两个,两个均竖直嵌设于重组竹梁体100内,均靠近重组竹梁体100外壁20mm处布置,并与重组竹梁体100胶结、热压成型。Referring to FIG. 4 , in another embodiment of the present invention, the invention comprises: a reconstructed bamboo beam body 100 is a rectangular parallelepiped with a height of 150 mm, a width of 100 mm, and a length of 6000 mm; a steel plate has a total width of 2 mm, a height of 130 mm, and a length of 5800 mm; the reconstructed bamboo beam body 100 is formed by gluing a plurality of bamboo fiber bundles; two steel plates 200 are provided, both of which are vertically embedded in the reconstructed bamboo beam body 100, and are arranged 20 mm close to the outer wall of the reconstructed bamboo beam body 100, and are glued and hot-pressed with the reconstructed bamboo beam body 100.
有利的是,以上两个实施例中,钢板200上垂直其长度方向开设有多个通孔201,通孔201填充有竹纤维,竹纤维与竹纤维束胶结,钢板上设置通孔在对刚度影响不大的前提下,达到节省钢材的目的,提升经济效益;且其均匀的布置在钢板中,但无需开在离钢板上下边缘较近的地方,操作方便;同时通孔内填充竹纤维,竹纤维与重组竹梁体的竹纤维束胶结,由此,能够增强钢板和重组竹之间的粘结效果,进而提高两者的结合能力。Advantageously, in the above two embodiments, a plurality of through holes 201 are provided on the steel plate 200 perpendicular to its length direction, and the through holes 201 are filled with bamboo fibers, which are bonded to bamboo fiber bundles. The through holes are provided on the steel plate without having a significant impact on the rigidity, thereby achieving the purpose of saving steel and improving economic benefits; and they are evenly arranged in the steel plate, but do not need to be opened close to the upper and lower edges of the steel plate, which is convenient for operation; at the same time, the through holes are filled with bamboo fibers, which are bonded to the bamboo fiber bundles of the reconstructed bamboo beam body, thereby enhancing the bonding effect between the steel plate and the reconstructed bamboo, thereby improving the bonding ability of the two.
本发明还提供了一种内置竖向钢板增强重组竹梁制备方法,包括以下步骤:将竹管劈裂成条状,将劈裂的竹条压成竹篾并捆绑成竹纤维束,然后浸胶备用;根据使用情况确定内部具有钢板,包括通孔规格、形状、数量;确定钢板位于重组竹梁体内的位置和数量(单板、双板、厚度),让梁具有足够的刚度;将钢板缠绕竹纤维后浸胶干燥备用,使钢板与重组竹之间获得更好的粘结效果;然后制模,在模具内竖直放置钢板,铺设浸胶的竹纤维束,使浸胶的竹纤维束和浸胶干燥的钢板热压成型。The present invention also provides a method for preparing a reconstructed bamboo beam reinforced with a built-in vertical steel plate, comprising the following steps: splitting a bamboo tube into strips, pressing the split bamboo strips into bamboo strips and bundling them into bamboo fiber bundles, and then dipping them in glue for later use; determining whether there is a steel plate inside according to usage, including the specifications, shape, and quantity of the through holes; determining the position and quantity (single plate, double plate, thickness) of the steel plate in the reconstructed bamboo beam body so that the beam has sufficient rigidity; wrapping the steel plate with bamboo fibers, dipping it in glue, and drying it for later use, so as to obtain a better bonding effect between the steel plate and the reconstructed bamboo; and then making a mold, placing the steel plate vertically in the mold, laying the glue-dipped bamboo fiber bundles, and hot-pressing the glue-dipped bamboo fiber bundles and the glue-dipped and dried steel plate.
由此,本发明内置竖向钢板在重组竹梁加工工程中,直接胶结热压形成,无需开槽,也不必二次加工,因此可以保证梁的整体性。钢板竖向放置,能够有效提高梁的刚度,解决重组竹梁作为受弯构件挠曲变形过大的问题。通孔均匀布置在钢板中,但无需开在离钢板上下边缘较近的地方,操作方便;同时钢板开孔能够增强钢板和重组竹之间的粘结效果,进而提高两者的结合能力,在对刚度影响不大的前提下,达到节省钢材的目的,提升经济效益。在重组竹梁内部放置竖向钢板提高重组竹梁刚度,这种增强方式方便、有效,同时可以避免钢板腐蚀,增强了构件的安全性和耐久性。Therefore, the built-in vertical steel plates of the present invention are directly bonded and hot-pressed in the processing of the reconstructed bamboo beams, without the need for grooving or secondary processing, so the integrity of the beams can be guaranteed. The vertical placement of the steel plates can effectively improve the rigidity of the beams and solve the problem of excessive flexural deformation of the reconstructed bamboo beams as bending members. The through holes are evenly arranged in the steel plates, but do not need to be opened close to the upper and lower edges of the steel plates, which is convenient for operation; at the same time, the holes in the steel plates can enhance the bonding effect between the steel plates and the reconstructed bamboo, thereby improving the bonding ability of the two, and achieving the purpose of saving steel and improving economic benefits without greatly affecting the rigidity. Placing vertical steel plates inside the reconstructed bamboo beams to improve the rigidity of the reconstructed bamboo beams is a convenient and effective way of reinforcement, and can also avoid corrosion of the steel plates, thereby enhancing the safety and durability of the components.
