Description

一种圆套筒钢木组合节点及其安装方法 技术领域
本发明属于木建筑节点设计领域，具体涉及一种圆形木柱与X型木梁连接的圆套筒钢木组合节点及其安装方法。
背景技术
在注重环保的现代建筑领域中，木结构建筑作为一种低耗能、轻材料的绿色环保建筑，具有巨大的应用潜力和研究价值。木结构具有施工周期短、节能环保和抗震耗能能力强的特点，在设计上具有布置灵活、隔音削震的优点。
然而在木结构建筑中，节点处是整个结构中最为重要的区域之一。传统的纯木节点，易发生破坏损耗的位置是柱、梁的传力交叉处，现在的节点多为纯钢构件节点，通过将钢片插入到木头内进行连接，易产生应力集中，且沿开口方向易发生顺纹理开裂；另外，为了保证梁的基本传力，竖向柱的传力截面常常遭削弱，存在整体性、受力性能不好的情况，抗震性能相对其他位置也较弱。
发明内容
本发明提供一种新型的圆套筒钢木组合节点设计，对FRP圆形木柱和X型木梁的连接进行创新设计，以加强竖向柱的传力能力，保证梁的传力在节点处不会对柱的传力造成不良影响，且安装操作简单。
本发明是采用以下的技术方案实现的：一种圆套筒钢木组合节点，包括FRP圆形木柱、X型木梁、核心连接构件、弧形连接件和拼接外环板；FRP圆形木柱之间通过核心连接构件相连，X型木梁通过弧形连接件与核心连接构件相连，拼接外环板设置在弧形连接件的上下两端，通过拼接外环板和螺栓固定实现组合连接；

所述弧形连接件包括带孔弧形基板和两块带孔弧型钢板，两块带孔弧型钢板背向设置在带孔弧形基板上，且两块带孔弧型钢板之间所形成的空间与X型木梁的形状匹配，弧形连接件环绕核心连接构件的外圆周设置，带孔弧形基板通过木螺钉固定在相邻的两块填充木块上，带孔弧型钢板用以加紧X型木梁；带孔弧形基板上设有8个螺孔，与核心连接构件的每块填充木块上每侧的4个木螺钉孔对应，木螺钉穿过带孔弧形基板旋入木螺钉孔中，一块弧形连 接件固定在相邻两块填充木块上；两块带孔弧型钢板间距稍大于X型木梁腹板厚度，带孔弧形钢板上有竖向4个螺栓孔、水平2个螺栓孔，X型木梁的腹板插入带孔弧形钢板之间，水平方向螺栓穿过弧形钢板、X型木梁腹板、弧形钢板螺母旋紧，竖直方向螺栓穿过拼接外环板、X型木梁的翼缘、弧形钢板，并用螺母旋紧。
所述拼接外环板包括基板、设置在基板一侧的弧形箍环，基板的表面设置有螺栓孔，基板上还设置有连接卡头，相邻拼接外环板之间通过连接卡头相连，相邻拼接外环板连接后对核心连接构件中间部分起外箍作用，用以箍紧填充木块，并与弧形连接件、X型木梁通过螺栓连接为整体以传递梁内力。
进一步的，所述FRP圆形木柱包括圆形木质柱以及设置在圆形木质柱外表面的FRP纤维布，通过在外层缠绕FRP纤维布实现对其结构强度的加强。
进一步的，所述连接套筒的上下两端设置有扇形拼接头，圆型钢套板上设置有与扇形拼接头相配合的对接卡槽，扇形拼接头卡入对接卡槽实现圆型钢套板和连接套筒的连接。
进一步的，所述填充木块上设置有与贯穿钢筋相配合的通槽以及与扇形拼接头相配合的缺口，实现填充木块与圆型钢套板的紧密配合。
进一步的，所述连接卡头与基板所在平面呈45°夹角，以保证传力仍通过形心线上。
进一步的，所述圆型钢套板上还设置有用以拉紧贯穿钢筋的对拉螺栓，以施加预应力增强整体性，提高核心连接构件的整体性能。
本发明另外还提出一种圆套筒钢木组合节点的安装方法，包括以下步骤：
A、将圆型钢套板套在已注胶的FRP圆形木柱上，在贯穿钢筋上有对拉螺栓，将内有圆实木的连接套筒的扇形拼接头旋入圆型钢套板相应侧的对接卡槽内；
B、将连接套筒固定在圆型钢套板之间，填入4块填充木块，并用胶粘合成整体；
C、用木螺钉将4块弧形连接件安装在填充木块的相应位置，且每一块充填构件固定在相邻两块填充木块上，4块弧形连接件连接后形成一套筒环绕在核心连接构件上；
D、将所述拼接外环板的紧靠弧形连接件安装，并用螺栓连接成环，以箍紧填充木块；
E、旋紧贯穿钢筋上的对拉螺栓，施加适宜预应力，使核心连接构件连接紧密，加强核心连接构件整体性；
F、将FRP圆形木柱插入圆型钢套板相应侧套筒内，并在钢筋孔内注胶，完成竖向FRP圆形木柱和核心连接构件的安装；
G、将X型木梁的一端插入弧形连接件的两块带孔弧型钢板之间，并插入高强螺栓连接；用螺栓将弧形连接件、X型木梁和拼接外环板连接成一个整体，完成水平方向梁的安装，进而完成圆套筒钢木组合节点的安装。
与现有技术相比，本发明的优点和积极效果在于：
本方案所提出的圆套筒钢木组合节点整体为全拼接结构设计，节点核心区为连接套筒设计，内有实木的连接套筒通过卡槽连接圆型钢套板，填入填充木块胶接，再在贯穿钢筋上通过对拉螺栓，连接套筒的设计能够有效保证节点竖向承载力，且通过对拉螺栓的预应力能有效增强结构抗震能力；水平方向荷载由环形拼接板承担，竖向荷载由连接核心构件承担，承载力高，保证了竖向传力无影响，水平和竖向传力无交叉；
现场为完全装配式施工安装，仅由螺栓连接和胶粘合，操作简单、安装快速、质量高，能满足在有特殊竖向承载的木结构建筑的设计要求，可用于竖向承载、强柱要求极高的木结构，在中高层木建筑中有具有巨大的市场潜力。
