具体实施方式
下面结合附图对本发明作详细描述：
实施例一
请参考图3至图9、图16、图18至图22和图24，本发明实施例一提供一种结构柱的模板，结构柱的模板，包括在钢立柱510的径向方向上设置阶梯状的结构面模板600，所述结构面模板600为M层，包括垂直于钢立柱510的轴向中心向外分布且带有与所述钢立柱510直径相同的第一中心孔611的第一层模板610，以及位于所述第一层模板610上的第二层模板620至第M层模板，其中M≥2；沿所述结构面模板600的边界垂直延伸设置且位于所述钢立柱510 外围的侧面模板640。
本发明实施例一提供的结构柱的模板，通过M层模板构成的阶梯状的结构面模板600能够使先期结构柱的结构面形成阶梯面，与先期结构柱的结构面为平面的方案相比，增大了施工后的先期结构柱在其结构面的接触面积，从而使先后期施工的结构柱的交界面为阶梯面而非平面，提高了先期结构柱与后期结构柱的结合效果，提高了先后期结构在交界面的结构稳定性，提高了先后期结构柱在交界面的施工节点处的工程质量。
请参考图3至图9、图16、图18至图22和图24，本发明实施例一提供的结构柱的模板中的结构面模板600可以采用以下两种层叠方式。本发明实施例中结构面模板600的M层模板包括但不限于3层模板，还可以是2层模板、4层模板、5层模板和6层模板等。模板的层数越多，形成的结构柱的结构面的阶梯面越多，则接触面积越大，则先期结构柱与后期结构柱的结合效果越好，其交界面的结构稳定性越好，工程质量越高。
结构面模板层叠方式一：
请参考图3至图9和图16，该模板层叠方式一中，所述第二层模板620至第M层模板为沿第一层模板610的边界向钢立柱510的轴向中心方向延伸且面积依次递减的矩形环状板。以M＝3的层叠模板为例，本层叠方式一中第一层模板610、第二层模板620至第三层模板630的面积依次递减的矩形环状板，且沿第二层模板620、第三层模板均是沿第一层模板610的边界向钢立柱510的轴向中心方向延伸的由于其是沿第一层模板610的边界向钢立柱510的轴向中心方向延伸，通过第一层模板610的边界可实现第二层模板620至第M层模板的快速定位，以便于第二层模板620、第M层模板的层层铺设施工，从而快速形成层叠的M层模板为阶梯状。请参考图13，该结构面模板层叠方式一能够形成结构柱呈中心高边界低的阶梯面的结构面。
结构面模板层叠方式二：
请参考图18至图22和图24，该结构面模板层叠方式二中，所述第一层模板610至第M层模板为垂直于钢立柱510的轴向中心向外分布、带有与所述钢立柱510直径相同的中心孔且面积依次递减的矩形板。以M＝3层模板为例，请参考图18至图21，第一层模板610带有第一中心孔611，第二层模板620带有 第二中心孔622，第三层模板630带有第三中心孔631，其中第一中心孔611＝第二中心孔622＝第三中心孔631。请参考图23，该结构面模板层叠方式二，M层模板均以轴向中心为起点，每一层模板均需要与钢立柱511进行对准定位，其能够形成呈中心低边界高的阶梯状的结构面的结构柱。由于结构面模板600的M层模板均带有中心孔，其能够保证与钢立柱510的稳定连接。
请参考图7和图22，本发明实施例一提供的结构柱的模板，所述侧面模板640可以沿所述结构面模板600的边界垂直向上延伸设置。由此进行由上至下先后期结构柱的施工顺序。
请参考图16和图24，本发明实施例一提供的结构柱的模板，所述侧面模板640可以沿所述结构面模板600的边界垂直向下延伸设置。由此进行由下至上先后期结构柱的施工顺序。
本发明实施例一的侧面模板640的延伸方向可以向上或者向下，其可以根据施工环境所在空间局限性和便利性进行灵活的设置。
请参考图3、图5、图7、图18、图20和图22，本发明实施例一提供的结构柱的模板，在所述第二层模板620至第M-1层模板中的任意一个或者几个模板上设置有与钢筋套筒相对应分布的预留孔洞621。预留孔洞621用于定位钢筋套筒的位置。以M＝3层模板为例，预留孔洞621设置在第二层模板620上，其能够保证钢筋套筒连接钢筋后的稳定性和坚固性。
实施例二
请参考图9至图11、图13至图15和图16至图17，本发明实施例二提供一种阶梯面的先期结构柱580，包括钢立柱510，以及包裹所述钢立柱510施工的先期钢筋混凝土结构，所述先期钢筋混凝土结构包括先期混凝土540、预埋在所述先期混凝土540之内的先期钢筋520以及与所述先期钢筋520相对应分布且连接的钢筋套筒530，所述先期钢筋混凝土结构的结构面540a为阶梯面，所述阶梯面为N个梯级面，沿所述钢立柱510的轴向中心向外依次为第一梯级面至第N梯级面，其中N≥2。本发明实施例二是以N＝3个梯级面为例进行说明。其中钢筋套筒530可以为钢筋接驳器。其中图10至图11中的阶梯面的先期结构柱可以为图3至图9中的结构面模板600施工形成。其中所述先期钢筋混凝 土结构的结构面540a是指所述先期钢筋混凝土结构的上端面或者下端面。
请参考图8至图11，本发明实施例二提供的阶梯面的先期结构柱，所述钢筋套筒530纵向分布在第二梯级面至第N-1梯级面中的任意一个或者几个梯级面上。钢筋套筒530的纵向分布位置，能够使其与钢筋的连接更加可靠、稳定。由于钢筋套筒530分布在中间梯级面，而不是分布在第一梯级面和第N个梯级面上，故能够防止泥浆灌入钢筋套筒530，避免堵塞的情况。为了进一步防止钢筋套筒530灌入泥浆而堵塞，请参考图10，在浇筑混凝土540之前可以通过柱塞660对钢筋套筒530进行保护；请参考图11，在浇筑混凝土540之前也可以通过盖帽650对钢筋套筒530进行保护。
为了进一步防止钢筋套筒530灌入泥浆而堵塞，本发明实施例二提供的阶梯面的先期结构柱，所述钢筋套筒530位于所述先期钢筋混凝土结构的结构面一侧的端面与所处梯级面齐平。
请参考图10至图11，为了进一步防止钢筋套筒530灌入泥浆而堵塞，本发明实施例二提供的阶梯面的先期结构柱，所述钢筋套筒530位于所述先期钢筋混凝土结构的结构面一侧的端面沿所处梯级面向外延伸，并且所述钢筋套筒530向外延伸的延伸距离位于所述钢筋套筒530所处梯级面与上一梯级面之间。即所在梯级面<钢筋套筒530的延伸距离≤上一梯级面。
请参考图13至图14，本发明实施例二提供的先期结构柱，所述阶梯面540a包括但不限于三个梯级面，沿所述钢立柱510的轴向中心向外依次为第一梯级面540b、第二梯级面540c和第三梯级面540d，所述钢筋套筒530纵向分布在第二梯级面540c的梯级面上。
本发明实施例二提供的阶梯面的先期结构柱，由于先期钢筋混凝土结构的结构面为阶梯面并且梯级面为2个以上，相比于先期钢筋混凝土结构的结构面为平面构成的先期结构柱来说，先期结构柱的结构面为阶梯面增大了与后期结构柱的接触面积，则在先期结构柱与后期结构柱的交界面会形成阶梯状，即先后期施工的结构柱的交界面为阶梯面而非平面，从而提高了先期结构柱与后期结构柱的结合效果，提高了先后期结构在交界面的结构稳定性，提高了先后期结构柱在交界面的施工节点处的工程质量。
请参考图7至图11、图13至图17、图18至图25，本发明实施例二还提供 了一种上述的阶梯面的先期结构柱的施工方法，包括：
请参考图7、图16、图22和图24，施工如上述实施例一的结构柱的模板600；

请参考图9至图11、图13至图17、图22至图25，在模板内浇筑先期混凝土540形成阶梯面的先期结构柱。
本发明实施例二提供的阶梯面的先期结构柱的施工方法，能够形成上述阶梯面的先期结构柱。
实施例三
请参考图3至图25，本发明实施例三提供一种阶梯式交界面的结构柱500，包括如上述的阶梯面的先期结构柱580，以及位于所述先期结构柱580之上或者之下的后期结构柱590，所述先期结构柱580与后期结构柱590的交界面570为阶梯式。
请参考图3至图25，本发明实施例三还提供一种阶梯式交界面的结构柱的施工方法，包括：
请参考图3至图14、图16至图25，施工如上述的阶梯面的先期结构柱580；
请参考图10至图14，拆除先期结构柱的模板，施工后期结构柱的模板；
请参考图12，通过所述钢筋套筒530连接与所述先期钢筋520相对应分布的后期钢筋550；
