Description

无缝接长竹板材及其制造方法。 技术领域
本发明涉及一种户内外用板材， 尤其是一种以竹子为原料的无缝接长竹型 材及其制造方法。 背景技术
现在室内外采用的铺面或装饰用板材普遍追求古朴典雅， 而竹材以其优良 的质地及风味在该领域占有一席之地。 普通的竹板材通常都是采用竹条或竹板 胚经胶合压制而成的。 竹条或竹板胚在粘合后的普通压制工艺过程中包括三个 因素， 根据原料的不同厚度和性质调整对其进行不同温度、 不同压力、 不同施 压时间的制备工艺。
其中， 竹条指的是通过木工机械设备切割成长度、 宽度不等的原竹根据竹 子本身的可利用性， 切割成任意长度、 宽度的条状竹片； 而竹板胚指的是将竹条 从宽度或长度方向胶合压制而成形成的块状板材。与木材一样，对于大面积铺设 的竹板材来而言，原材料的接长必不可少。传统的加工工艺是在竹条或竹板胚的 端部设有凹槽或与之对应的凸榫， 相互连接。这种方法有两大缺点： 首先， 凹槽 和凸榫的连接方式仅是凸榫插接入凹槽内，最多依靠粘合剂进行粘合， 因此横向 连接强度不够； 其次， 由此制作的板材会形成接缝， 不仅不美观， 而且接缝还会 藏污纳垢， 更增加了清洗的难度。 竹子是中国产量巨大的自然资源， 虽然通常用来制作板材的竹材和木材看 似非常相似， 但实际上两者有着很大的区别。 竹子具有独特的构造， 其内部为 空心， 仅有一层竹肉可以用来制作板材， 另外， 竹子具有大头小尾的特点， 即 竹肉在根部的厚度远大于在顶部的厚度， 再加上竹子为筒形结构， 具有弧度， 使竹子在制作板材上的应用受到了极大的限制。 一般情况下， 一条刨去竹青、 竹黄后呈立方体形状的竹条单元， 其正常的厚度只有 0. 3〜1. 0cm， 宽度只有 0. 5〜2. 5cm， 几乎无法将其制成较长的板材。
传统的竹板材的加工通常采用竹条或竹板胚经胶合压制而成， 针对不同规 格的竹条或竹板胚以及粘合剂的性质， 选择不同的温度、 压力和施压时间。 为了达到接长的目的， 传统的加工工艺是在竹条或竹板胚的端部设有凹槽 或与之对应的凸榫， 相互连接。 这种方法有两大缺点： 首先， 凹槽和凸榫的连 接方式仅是凸榫插接入凹槽内， 最多依靠粘合剂进行粘合， 因此横向连接强度 不够； 其次， 由此制作的板材会形成接缝， 不仅不美观， 限制了竹子产品的加 工， 而且接缝还会藏污纳垢， 更增加了清洗的难度。
另外， 现有的竹材仅限于板材的制造， 尚未有竹型材概念的提出， 利用竹 子本身稳定性好， 不易变形， 硬度高、 强度大、 生产周期短等优异特点， 制造出 具有一定厚度、宽度和长度的竹型材，才能真正达到以竹代木、以竹代钢的目的。 发明内容
本发明所要解决的技术问题在于提供一种横向连接强度可靠，且接长后无明 显接缝的无缝接长竹板材。
本发明所要解决的另一技术问题在于提供一种无缝接长竹板材的制造方法。 本发明解决上述技术问题采取的技术方案是： 一种无缝接长竹板材， 由竹 条或竹板胚排列、接长而成，所述的竹条或竹板胚在长度方向上至少一个端部开 设有拉槽， 对应于拉槽在端部形成一榫钩；
一榫钩嵌入另一竹条或竹板胚的拉槽内， 该拉槽与榫钩的相互匹配， 两竹 条或竹板胚的榫钩相互卡扣连接。对于榫钩的截面形状而言可以采取各种不同形 状， 例如 S形弧面、 Z形面、 曲折面、 齿形面， 并不限于上述截面， 但截面不宜 过于复杂， 会导致加工不易。
所述的竹条或竹板胚一端设有的拉槽与对应该拉槽形成的榫钩形状相互匹 配。榫钩就能正好扣入并完全填补拉槽，这样相互连接的竹条或竹板胚就自然合 成一体， 且制成的整片竹板材厚度一致。并且， 由于采用这样的开拉槽工艺进行 多数复制所形成的竹条或竹板胚可以直接相互连接， 可以大大简化生产工艺。
所述榫钩的顶端面向内倾斜形成斜面，所述拉槽的侧内壁形成有与榫钩斜面 相抵顶的斜面。这种设置有两大显著效果， 首先， 向内倾斜的斜面能更容易的使 竹条或竹板胚两两相互扣接， 榫钩可以较容易的伸入拉槽内； 第二， 向内倾斜的 斜面很好的掩盖了两竹条或竹板胚连接时形成的接缝，从而使经粘合压制制得的 成品竹板材达到无缝连接的目的。
所述竹条或竹板胚两端分别开设有拉槽， 对应于拉槽在端部分别形成一榫 钩，二拉槽的开口方向相同或相反。本发明的拉槽可以开设在竹条或竹板胚的上 下表面， 亦可以开设在侧向表面。 设置方向相同或相反只是连接形式上的区别， 设置方向相同， 则相邻连接的竹条或竹板胚一正一反地拼接； 设置方向相反， 则 相邻连接的竹条或竹板胚同向连续拼接。
为了保证接长的竹板材不会因为受力集中而发生断裂，所述的接长竹条或竹 板胚排列时， 其连接位置至少有一部分错开。
进一步保证牢固性，所述的接长竹条或竹板胚排列时，其相邻的连接位置相 互错开。对于面积不大的竹板材而言， 所述的接长竹条或竹板胚， 其连接位置均 不在同一直线上。
所述的竹板胚为竹条从宽度或厚度方向上胶合压制成型的竹板胚。
本发明提供一种无缝接长竹板材的制造方法， 包括下列步骤：
第一步：将竹条或竹板胚在长度方向上至少一个端部开设拉槽，对应于拉槽在端 部形成榫钩；
第二步：将一榫钩伸入另一竹条或竹板胚的拉槽内，两竹条或竹板胚的榫钩相互 卡扣连接， 形成接长的竹条或竹板胚；
第三步： 将接长的竹条或竹板胚在宽度或厚度方向上粘合拼接；
第四步： 经普通工艺压制制成成品竹板材。
其中， 上述第二步中， 所述两榫钩相互卡扣连接的接触面上涂有粘合剂层， 以增加扣接强度。
所述榫钩的顶端面向外倾斜形成斜面，所述拉槽的侧内壁形成有与榫钩斜面 相抵顶的斜面。向外倾斜是另一种变形形式，从加工角度而言与向内倾斜的榫钩 无异， 但拼装没有向内倾斜设置那么容易。
所述竹条或竹板胚的榫钩和 /或拉槽的截面形状为 S形弧面、 Z形面、 曲折 面、 齿形面、 爪形面、 不规则面中的一种。 对于榫钩和 /或拉槽的截面形状而言 可以采取各种不同形状，并不限于上述截面，竹条或竹板胚具有对应拉槽及榫钩 的均在本发明保护范围之内， 但截面不宜过于复杂， 会导致加工不易。 由于竹条或竹板胚连接成竹板材后， 目的是达到上表面无接缝， 因此位于上 表面的榫钩顶端设置斜面即可，与之对应的拉槽内壁也具有斜面，位于下表面的 榫钩和拉槽可以不设斜面； 当然也可以上、 下表面的抵顶接缝处均设置成斜面， 这使竹条或竹板胚具有对称结构， 加工更容易。
本发明所要解决的技术问题在于提供一种无缝接长竹型材， 通过接长、 粘 合、 压制， 实现长度、 宽度、 厚度上的复合， 制成柱状、 板状等的竹型材。
本发明解决上述技术问题所采取的技术方案是：一种无缝接长竹型材， 由竹 条或竹板胚排列、接长而成， 其中， 所述的竹条或竹板胚通过长度方向上相互对 应的拉槽、榫钩密配合接长， 宽度和厚度方向上均通过有序排列的竹条或竹板胚 相互复合， 构成设定尺寸的竹型材。
采用本发明结构， 对竹条的选材无特殊要求， 以最大限度的利用竹资源为 前提， 可以选用尺寸利用率最高的竹条单元进行接长、复合， 利用率最高的竹条 单元长度为 10〜200cm， 宽度为 0· 5〜2· 5cm， 厚度为 0· 3〜1· 2cm。
所述的密配合接长是指竹条或竹板胚在长度方向上至少一个端部开设有拉 槽或榫钩， 一竹条或竹板胚的榫钩嵌入另一竹条或竹板胚的拉槽内相互卡扣连 接， 其中， 所述的拉槽与榫钩的对接面分别为向内或向外的斜面。
具体的， 在开设有拉槽的端部， 对应于拉槽形成榫钩， 该拉槽与榫钩形状相 互匹配，因此任意竹条或竹板胚的榫钩都能正好扣入并完全填补另一竹条或竹板 胚的拉槽，这样相互连接的竹条或竹板胚就自然合成一体，如此实现无限接长的 目的。
另外，所述榫钩的顶端面为向内或向外的斜面，所述拉槽的侧内壁形成有与 榫钩斜面相抵顶的斜面。这种斜面设置有两大显著效果， 首先， 向内倾斜的斜面 能更容易的使竹条或竹板胚两两相互扣接，榫钩可以较容易的伸入拉槽内；第二， 向内倾斜的斜面很好的掩盖了两竹条或竹板胚连接时形成的接缝，从而使经粘合 压制制得的成品竹板材达到无缝连接的目的。
本发明的竹型材，至少应当在外表面处采用以上斜面拼接结构，保证竹型材、 竹板胚具有光洁无缝的外观。
所述竹条或竹板胚两端分别开设有拉槽， 对应于拉槽在端部分别形成一榫 钩， 二拉槽的开口方向相同或相反。 拉槽可以开设在竹条或竹板胚的上下表面， 亦可以开设在侧向表面。设置方向相同或相反只是连接形式上的区别，设置方向 相同， 则相邻连接的竹条或竹板胚一正一反地拼接； 设置方向相反， 则相邻连接 的竹条或竹板胚同向连续拼接。
针对上述的无缝接长竹型材的制造方法， 对竹条或竹板胚进行长、 宽、厚方 向上的复合， 依序为：
步骤一： 在竹条或竹板胚的端部开设拉槽或榫钩， 在拉槽或榫钩以及对接 面处涂胶， 并在竹条或竹板胚的厚度方向或宽度方向上涂胶， 以方便两个或两 个以上竹条或竹板胚连续卡扣、 粘合接长， 其中， 涂胶应先将竹条或竹板胚的 上下表面平整砂光， 再涂覆粘合剂， 待粘合剂干燥， 备用；
步骤二：先在长度方向接长，竹条或竹板胚通过相互对应的拉槽和榫钩卡扣 接长到设定尺寸；在宽度和厚度方向上采用压制复合至设定尺寸，具体为将每一 批次相同厚度的多数条涂胶的竹条或竹板胚扣接接长并在厚度方向上依序排布 后， 复合压制成单层板材 B; 和 /或将每一批次相同宽度的多数条涂胶的竹条或 竹板胚扣接接长并在宽度方向上依序排布后， 在压机上复合压制成单层板材 A; 步骤三：最后，将表面涂胶的单层板材 A和 /或单层板材 B叠置到设定尺寸， 一次压制复合或长度方向上分段压制复合制成竹型材。
在上述方案的基础上， 步骤三中， 将单层板材 A和 /或单层板材 B叠置到设 定尺寸的方法包括： 单层板材 A之间叠置， 或将单层板材 B之间叠置， 或将两 块单层板材 A中间夹一块单层板材 B叠置， 或将两块单层板材 B中间夹一块单 层板材 A叠置方法中的一种。
在上述方案的基础上， 压制复合成竹型材的方法包括：
一次压压制复合成型方法： 将单层板材 A叠置， 或将单层板材 B叠置， 或 将两块单层板材 A中间夹一块单层板材 B叠置， 或将两块单层板材 B中间夹一 块单层板材 A 叠置， 在压机下进行压制复合， 制成竹型材， 这里所说的单层板 材 A或单层板材 B叠置为两块或两块以上的叠置；
或者， 进行二次压制复合成型： 在经过一次复合成型的竹型材的上表面和 / 或下表面涂胶， 叠置单层板材 A或单层板材 B， 在压机下进行二次压制复合； 也可， 进行二次以上的压制复合成型： 重复二次复合成型的步骤， 进行二次 以上压制复合至设定尺寸的竹型材。 在上述方案的基础上， 一次压制复合成型是将三块或以上单层板材 A和 /或 单层板材 B叠置， 在压机下进行压制复合， 制成厚度在 150mm内的复合竹型材。
热压复合工艺是利用压机上的压机板的传热传入受压的材料内部和胶合处 使其胶粘剂固化而胶合在一起， 另外如要把一定厚度的多层型材胶合在一起，采 用二次及二次以上的复合成型方法， 即在单层板材表面先进行平整砂光再涂胶， 进行排列后，进热压机复合， 用此热压复合方法具有热传播速度快、 胶合固化时 间短、不会破坏内在胶合强度和产品性能， 使产品质量有保障。而按传统的方法 热压一定厚度的产品就无法做到热固化胶合，其产品质量没有保障，且胶合强度 差。
因此， 本发明针对厚度在 150mm以内的竹型材， 可使用一次复合成型。对于 厚度大于 150mm的竹型材采用二次及二次以上复合成型，利用本发明方法可生产 出： 厚度 10讓〜1000讓、 宽度 10讓〜1300讓和任意长度的无逢接长竹型材。
所述的压制复合为热压复合， 热压温度为 85〜165°C， 压力为 5〜35kg/cm2。 所述叠置是指单层板材之间同向叠置或纵横错相叠置。
由于竹子会发霉，且霉变速度比木材快， 因此需在制备之前对原材料进行防 腐处理， 所述的竹条在接长前经过碳化处理， 其中， 所述的碳化处理包括： 水碳 化处理、 湿碳化处理或干碳化处理。
所述的接长竹条或竹板胚在厚度和 /或宽度方向排列时， 其相邻的连接位置 相互错开。
针对上述制造方法制得的无缝接长竹型材产品，用作户内外的柱、梁、扶手、 平台地砖、 平台地板、 室内外地板、 汽车厢板、 船用踏板、 集装厢板、 建筑模板 等， 代替了用木材为原料的木制产品和建材类木制产品的一切用材。
所述的竹板胚还包括用竹丝或竹篾压制而成的类似竹板胚的材料。
本发明的有益效果是：
1、 本发明的无缝接长竹板材具有结构新颖的拉槽与榫钩结构， 使经粘合压制而 成的产品达到无缝的表面效果；
2、 本发明具有横向拉接效果， 加强了横向的连接强度；
3、 本发明的工艺提高了竹材料的利用率和产品的附加值， 节省了竹子资源， 保 护了竹资产； 4、本发明无缝接长竹板材的静曲强度，硬度等理化性能与常规竹地板并无二致， 但是变形度却大大降低。
5、 本发明解决了竹子用品包括地板， 家具板， 户外地板， 园林制品， 建筑材料 等在应用上的长度受限制问题，可以以任意长度进行连接，从而真正实现了以竹 代钢， 以竹代木的目标。
6、 本发明所述无缝接长竹型材具有结构新颖的拉槽与榫钩结构， 榫钩顶端设置 成斜面， 使经粘合压制而成的产品达到表面无缝的效果， 且具有横向拉接效果， 加强了横向的连接强度， 大大提高了产品的稳定性；
7、 本发明大大提高了竹材料的利用率和产品的附加值， 节省了竹子资源， 保护 了竹资产；
8、 本发明可根据不同要求制成任意长、 宽、 厚的竹型材， 可制成柱、 梁、 扶手、 平台地砖、 平台地板等各种产品， 竹材具有强度高、 硬度高和变形性小的特点， 可真正实现以竹代钢， 以竹代木的目标。 附图说明
