周边拉结柱12的两端均高于中心柱体11，使自拉结组合柱1的两端分别形成中心柱体形状的凹槽。自拉结组合柱两端分别设置有定位盖板13，定位盖板13的内表面上设置有凸起1301，如图7所示，凸起1301的形状与中心柱体的截面形状相同，从而使定位盖板13从上下两端分别插入时，凸起部分1301插入凹槽中，使整个柱体严密连接不留缝隙。安装好定位盖板后，将定位盖板13与周边拉结柱12通过FRP预应力筋14连接，FRP预应力筋14围绕中心柱体11均匀布置，以使FRP预应力筋能够在节点中合理受力，避免出现某根FRP预应力筋应力过大的现象。
如图8所示，组合梁2包括上下两块翼缘板21和位于两翼缘板之间的两块平行的腹板22，翼缘板的内侧面设置有榫头2101，腹板的顶面和底面上均开有与榫头2101对应的卯孔2201，翼缘板与腹板之间通过榫卯连接。两块翼缘板端部设置有侧向榫头2102，侧向榫头2102与周边拉结柱外侧面的侧向卯孔1205相匹配，侧向榫头2102插入侧向卯孔1205中，使组合梁2与周边拉结柱12之间通过榫卯连接。
梁柱加强套件3包括柱体外环板31和角部连接块32，如图9所示，柱体外环板为环状，包括呈十字形分布的四块连接板3101，柱体外环板31套在自拉结组合柱上，柱体外环板31的内壁轮廓与自拉结组合柱1的外轮廓相匹配，两连接板3101的连接处设有直角凸起3102，因此柱形外环板31具有四个与直角夹角1203相匹配的直角凸起3102，连接板3101与翼缘板21之间通过螺栓连接。
如图10所示，角部连接块32的截面为直角三角形，角部连接块32插入上、下两柱体外环板31之间、且位于相邻周边拉结柱12之间的直角夹角1203中，角部连接块32与柱体外环板31通过螺栓连接。
如图11所示，本实施例的自拉结钢木组合节点的安装步骤如下所述。
第一步，将中心柱体11与其外侧的四块周边拉结柱12榫卯连接，相邻两周边拉结柱12之间榫卯连接。
第二步，将腹板22与其上、下两侧的翼缘板21榫卯连接形成组合梁2，将翼缘板端部的侧向榫头2102插入周边拉结柱12外侧面的侧向卯孔中，使组合梁2与周边拉结柱12榫卯连接。
第三步，将柱体外环板31从上、下两个方向分别套在自拉结组合柱1上，组合梁2的上、下两侧分别安装有柱体外环板31，柱体外环板31与组合梁2的翼缘板21通过螺栓连接。
第四步，安装角部连接块32。将角部连接块32插入上、下两个柱体外环31之间、且位于相邻周边拉结柱12之间的直角夹角1203中，角部连接块32与柱体外环板31之间通过螺栓连接.
第五步，安装上、下两块定位盖板13。将定位盖板13的凸起1301分别插入自拉结组合柱1中心的凹槽内，实现定位盖板13与自拉结组合柱1之间的连接。
第六步，安装FRP预应力筋14。将FRP预应力筋14穿过定位盖板13和周边拉结柱12。
实施例2
本实施例与实施例1的区别在于，组合梁与自拉结组合柱之间通过梁柱连接块4连接，如图12所示，梁柱连接块4的一个侧面上设置有水平榫头41，对 应的另一侧面的上下两端均设置有水平插孔42，水平插孔之间设置有竖向榫头43。
本实施例中，由于组合梁2是与梁柱连接块4连接的，因此组合梁2的结构也发生了改变，如图13所示，腹板前端开有竖向卯孔2202，翼缘板内侧的榫头和腹板顶面及底面的卯孔2201均没有贯穿全长，而是短了一截。
连接时，首先将梁柱连接块4的水平榫头41插入周边拉结柱的侧向卯孔1205中，然后将腹板22与梁柱连接块4榫卯连接，最后将翼缘板21与腹板22榫卯连接的同时将翼缘板21端部插入水平插孔42中并通过螺栓连接。如图14所示。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
