一种预制钢梁与楼板平齐装配的设计及快速施工方法 技术领域
本发明涉及一种应用在建筑工程结构中的预制装配式梁和楼板平齐装配的设计与快速施工方法，该发明尤其适用于现场焊接不易且对空间高度要求较高的建筑工程中。
 背景技术
在建筑工程结构中，预制钢梁与楼板的连接方法至关重要，直接关系着空间利用、施工进度和工程造价。现阶段我国装配式梁板连接方式大多是将板通过不同的方式搭在梁的上方，进而完成楼盖体系的施工，造成了空间利用率一定程度上的降低，如上海前滩某建筑工程就提出了将楼板与钢梁上平面平齐的要求。此外，现行的装配式楼板连接方法多存在大量的现场焊接、现场支模、搭设脚手架等，容易影响施工质量并导致施工进度迟缓。
因此，需要一种新型的预制钢梁与楼板平齐设计及其快速施工方法，以提高空间利用率、缩短施工时间等。基于此，本发明提出了一种新型的预制钢梁与楼板平齐装配的设计及其快速施工方法，使楼板与钢梁顶面平齐，且可避免现场焊接，具有空间利用率高、施工质量更可控等优点；当使用预制装配混凝土楼板或钢板混凝土组合楼板时，无需现场支模和搭设脚手架，具有施工速度快等优点。
 技术问题
本发明提出了一种预制钢梁与楼板平齐装配的设计及快速施工方法；该梁板体系具有空间利用率高、不施工快速、需要现场焊接、安装方便等优点。
 技术解决方案
本发明的技术方案：
一种预制钢梁与楼板平齐装配的设计方法，主要针对预制装配式梁板子结构进行设计，所述的预制装配式梁板子结构包括钢筋混凝土楼板1、预制型钢梁2、梁板间的现场浇筑混凝土3；
所述的钢筋混凝土楼板1端部部分钢筋端头设置钢筋预制圆环4，用于连接预制型钢梁2的竖向预焊接栓钉5；
所述的预制型钢梁2的上翼缘为“几”字形，由水平翼缘6、竖直翼缘7和顶翼缘8共同组成，其中竖直翼缘7的高度与钢筋混凝土楼板1的厚度相同；水平翼缘6上布置梁加劲肋9，用于提高水平翼缘6的刚度及承载力，防止水平翼缘6出现局部变形；同时水平翼缘6上焊接有竖向预焊接栓钉5，竖向预焊接栓钉5位置与钢筋混凝土楼板1端部的钢筋预制圆环4一一对应；竖直翼缘7和顶翼缘8组成的内空间浇筑有翼缘内侧混凝土10，用于防止翼缘在受压状态下的变形；竖直翼缘7内侧设置水平向预焊接栓钉11，用于固定翼缘内侧混凝土10，防止其脱落。
一种预制钢梁与楼板平齐装配的快速施工方法，当楼板为钢筋混凝土楼板时，步骤如下：
步骤一、工厂预制钢筋混凝土楼板1，并在其端部的部分钢筋端头设置预制圆环4；
步骤二、在工厂预制型钢梁2，在其水平翼缘6上设置竖向预焊接栓钉5并设置加劲肋9，竖向预焊接栓钉5位置与钢筋混凝土楼板1端部的钢筋预制圆环4一一对应；在其竖直翼缘7内侧焊接水平向预焊接栓钉11；
步骤三、将预制型钢梁2倒置，以其竖直翼缘7和顶翼缘8为模板，完成工厂浇筑翼缘内侧混凝土10，其中水平向预焊接栓钉11用于固定翼缘内侧混凝土10；
步骤四、现场装配，将钢筋混凝土楼板1搭在预制型钢梁2的水平翼缘6上，并使钢筋混凝土楼板1上的钢筋预制圆环4一一对应套在竖向预焊接栓钉5上；
步骤五、以预制型钢梁2的水平翼缘6、竖直翼缘7以及钢筋混凝土楼板1的侧面为模板，在预制型钢梁2和钢筋混凝土楼板1之间的空隙处现场浇筑混凝土3，完成梁板子结构的施工。
所述的楼板不限于预制钢筋混凝土楼板1，当楼板为其他形式的现浇楼板时，如果现场允许搭脚手架和支模板，支模后进行楼板钢筋施工时将部分楼板端部的钢筋预制圆环4套一一对应套在竖向预焊接栓钉5上，然后现场浇筑混凝土；如果现场不搭脚手架，使用钢板混凝土组合楼板，即在工厂将钢板或压型钢板端部预先焊接钢筋预制圆环4，现场装配时将钢板端部的钢筋预制圆环4套在预制型钢梁2的竖向预焊接栓钉5上，然后以钢板为模板现场浇筑混凝土。
 有益效果
本发明的有益效果在于，与现有技术相比，本发明提出的预制钢梁与楼板平齐装配方法：(1)既能满足梁板的承载力要求，还能提高建筑的空间利用率；(2)本发明的梁、板均可在工厂预制完成，施工时只需现场拼装并浇筑少量混凝土即可完成，避免了搭设脚手架和支模，实现了快速施工，大大节约了施工时间；(3)本发明避免了现场焊接，能更好地保障施工质量。
