为了能够更加清楚地理解本发明的上述目的、特征和优点，下面结合附图及实施例对本发明做进一步说明。
实施例1，一种装配式钢木组合节点，如图1和图10所示，包括方形管柱1、钢木组合梁2以及连接方形管柱1和钢木组合梁2的梁柱连接组件3；
所述方形管柱1包括连接角柱4和连接侧板7，如图2和图3所示，方形管柱1由四个连接角柱4和四块连接侧板7相互拼接形成一中空的管柱结构，其中，连接角柱4为柱钢，耐腐蚀性高，连接侧板7为木板。钢木组合柱与纯钢结构相比，单位质量上的承载力更高，可在一定程度上减轻整体结构的重量，提高整体寿命。所述连接角柱4的横截面为90°圆弧形结构，且沿连接角柱4两侧的侧棱上还设置有燕尾型插接孔5；对应的在连接侧板7的侧棱上设置有与燕尾型插接孔5匹配的燕尾型插接头6，连接角柱4和连接侧板7通过插接头6和插接孔5插接连接为一体。另外，考虑到每片木材的长度不是固定的，为了更加充分利用材料，所述连接侧板7可通过不同高度木板进行拼接组合，如图4-5所示，所述连接侧板7包括上侧木板71和下侧木板72，上侧木板71下端设置一字型插接头10，下侧木板72上端开设有与一字型插接头10匹配的凹型槽9，上侧木板71和下侧木板72通过拼插形式形成与连接角柱4相同的高度，拼接后的结构示意图如图6所示。

继续参考图7，所述中柱连接组件包括方形实心木柱16、两组相对应斜对称设置的第一方形木梁。所述方形实心木柱16的一对对边开设有正T型滑槽12，正T型滑槽12内具有贯穿整个方形实心木柱16的第一通孔121；相对应的方形实心木柱16的另一对对边开设倒T型滑槽14，倒T型滑槽14内具有贯穿整个方形实心木柱16第二通孔141，本实施例中，第一通孔121位于正T型滑槽12的上部，第二通孔141位于倒T型滑槽的下部，以实现巧妙配合；所述第一方形木梁包括第一组方形木梁和第二组方形木梁，第一组方形木梁包括第一插接头木梁51和第一异形凹槽木梁52，第一插接头木梁51上设置有第一长条状插接头511，且第一长条状插接头511沿第一插接头木梁51本体的上沿设置，且第一插接头木梁51上安 装有第一长条状插接头511的端面与所述T型滑槽相匹配，第一异形凹槽木梁52的上表面开设有与第一长条状插接头511形状匹配的第一异形凹槽521，且第一长条状插接头511插入第一通孔与第一异形凹槽521嵌合后，沿第一异形凹槽的两侧形成两个拼接槽19；第二组方形木梁包括第二插接头木梁53和第二异形凹槽木梁54，第二插接头木梁53上设置有第二长条状插接头531，且第二长条状插接头531沿第二插接头木梁53本体的下沿设置，且第二长条状插接头531的端面与所述倒T型滑槽的表面相匹配，第二异形凹槽木梁52的下表面开设有与第二长条状插接头531形状匹配的第二异形凹槽，且第二长条状插接头511插入第二通孔与第二异形凹槽嵌合后，沿第二异形凹槽的两侧形成同样两个拼接槽，即第一组方形木梁和第二组方形木梁的设计相配合，并恰好连接为一个整体。另外，在四个木梁(51，52，53，54)的尾部还设有与木腹板对接插头24相对应的对接插槽15。带长条形插接头的木梁穿过实心木柱与相对应的带异形凹槽的木梁连接，并在连接处的拼接槽内插入固定木片连接为整体。
如图8所示，为钢木组合梁2与梁柱连接组件3的连接示意图，由木腹板23的对接插头24插入对接插槽15中，为了进一步提高连接强度，在四个木梁两侧还设置有固定插槽18，通过固定木片25插入固定插槽18进行组合，上、下翼缘卡在木梁上下侧实现固定配合。如图9所示，为下翼缘11与梁柱连接组件3的连接局部示意图，在四个木梁的下侧开设一个T型拼接槽22，对应的在下翼缘上设置有与T型拼接槽匹配的T型通孔，T型拼接槽22内部具有一滑移空间，工字型滑块20下部具有一与所述滑移空间相配合的拼接头，将工字型滑块20插入T型拼接槽并向左滑动(以图9所示方向为准)，然后插入填充木块21进行固定，把梁翼缘和梁柱连接组件连接起来，有效减少钻孔等方式产生的应力集中现象。
如图10所示，本实施例中所示中柱装配式梁柱组合节点的具体安装过程示意图：
第一步：分别组装好梁柱连接组件3和方形管柱，方向管柱包括上方形管柱和下方形管柱；
第二步：将组装好的梁柱连接组件3插入组装好的下方形管柱；
第三步：将木腹板的对接插头插入方形木梁端部对接插孔中；
第四步：将上、下翼缘通过翼缘插接滑槽与木腹板上下两侧的翼缘插接头连接，上翼缘通过一组固定木片连接固定，两侧通过固定木片固定，下侧通过工字型滑块及填充木块将下翼缘与方形木梁连接为一体；
第五步：将拼装好的上方形管柱插入梁柱连接组件上部的方形实心木柱。
实施例2、与实施例1的区别在于，中柱梁柱连接组件由角柱连接组件代替，对于角柱连接组件来说，如图11和14所示，其与中柱连接组件采用相似的设计原理，如图12所示，所示角柱连接组件同样包括方形实心木柱、两个相互垂直的第二方形木梁(13,17)以及两块 木栓26。方形实心木柱相邻两侧各开设I型滑槽27，一侧的I型滑槽27上部贯穿整个实心木柱，另一侧的I型滑槽的下部关贯穿整个实心木柱，第二方形木梁13和17上设置有与I型滑槽相配合的I型滑件29，且第二方形木梁13上的I型滑件29沿其上沿设置，第二方形木梁17上的I型滑件29沿其下沿设置，且I型滑件的端面形状与所述I型滑槽27的端面形状匹配，在I型滑件29的端部还设置有与木栓26尺寸相匹配的木栓孔28；本实施例中，所述第二方形木梁13和17的下侧同样开设有一个T型拼接槽，尾部带有两个与木腹板对接插头相对应的对接插槽，采用与中柱连接组件相同的设计及组装方式进行固定，方形木梁沿I型滑槽连接实心木柱，用木栓固定为一体。
本发明与纯木结构相比，(1)在相同截面下，钢木组合结构由于钢的侧向刚度大，可以提高结构的竖向承载力；(2)且与刚结构相比，本实施例中，柱侧板采用木结构，且方形管柱为空心，单位质量上的承载力更高，可在一定程度上减轻整体结构的重量，提高整体寿命；(3)梁的翼缘受拉，腹板受剪，本发明比工字型梁相比翼缘处不会发生局部屈曲，与方形木梁相比材料的利用率更高；(4)通过简单拼接进行整体组合，在地震作用下，更加易于构件的更替。钢材与木材结合形成的钢木组合结构在地震作用时，由于木材本身具有一定韧性，能具有良好的抗震性能；(5)所有构件可均在工厂完成，现场全部通过拼接连接，实现了完全装配化施工，避免现场焊接带来的质量问题，缩短施工周期。
以上所述，仅是本发明的较佳实施例而已，并非是对本发明作其它形式的限制，任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例应用于其它领域，但是凡是未脱离本发明技术方案内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与改型，仍属于本发明技术方案的保护范。
