Description

一种下行式双跨移动模架及施工方法 技术领域
本发明属于移动模架技术领域，特别涉及一种下行式双跨移动模架及施工方法。
 背景技术
移动模架现浇等截面预应力混凝土箱梁是世界桥梁先进的施工工法，施工时无需在桥下设置模板支架，具有施工工序简单，施工周期短，可连续施工等优势，且施工期间不影响桥下通车通航要求，在国内外取得广泛运用。
由于现有的移动模架需要进行合龙，合龙处需要进行固定，因此此处的强度决定整个工程的安全性，在进行合龙时，对横梁通过螺栓进行固定，固定繁琐，同时外模板的合龙处处于横梁顶部，由于此处缝隙上下贯通，当发生泄漏时，容易造成连续性泄漏，影响浇筑的安全性。
因此，发明一种下行式双跨移动模架及施工方法来解决上述问题很有必要，其能够在对横梁进行固定时，降低固定的繁琐性，并且提高外模板合龙处的紧密型，进而提高浇筑的安全性。
发明内容
针对上述问题，本发明提供了一种下行式双跨移动模架及施工方法，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：一种下行式双跨移动模架，包括主梁、主鼻梁、牛腿、推进平车、横梁、外模板、前吊梁和后吊梁，所述主梁的数量为两个，主梁通过多对横梁连接，横梁两两为一组，其底端通过螺栓连接；所述主鼻梁固定连接在主梁两端，牛腿为三对，分别位于主梁和主梁两端的主鼻梁底部，用于对主梁和主鼻梁进行支撑，且每对牛腿之间通过连接板连接，所述推进平车滑动连接在牛腿顶部，前吊梁和后吊梁分别位于主梁两端处的主鼻梁顶部，对主梁同一端的两个主鼻梁进行连接；所述外模板由对称的两部分组成，且两部分的接触处设置有贴紧连接装置，外模板的两部分分别与两个主梁固定连接。
优选的，所述贴紧连接装置包括贴合板，所述贴合板嵌入到外模板的两部分的连接处顶部，贴合板底部固定连接有多个竖杆，多个竖杆底端水平插接有同一个横杆，横杆外侧套接有多个斜杆，多个斜杆顶端均分的铰接在外模板的两部分底面处；所述竖杆底端滑动插接有移动杆，移动杆远离竖杆的一端为双头，且分别插接在同一对的两个横梁内。
优选的，所述移动杆外侧套接有多个圆台帽，且相邻两个圆台帽关于横梁镜像设置，圆台帽的大头端固定连接有插杆，插杆端部能够插接在横梁内，且圆台帽的小头端固定连接有回位弹簧，回位弹簧端部固定连接在移动杆外表面。
优选的，所述圆台帽的小头端转动连接有挡环，挡环的直径比圆台帽的小头端的直径大，且挡环表面开设有扇叶槽。
优选的，所述外模板顶部边缘处设置有抬升架，抬升架为皿字形结构。
优选的，所述横梁设在两根主梁之间，为型钢梁桁架结构，在横梁的中轴线位置一分为二，两端分别与主梁采用螺栓联结。
优选的，所述主鼻梁分为前后两部分，分别与主梁两端联结，为三角形钢桁结构，在纵向过孔时起导向及纵向平衡作用。
本发明同时公开了使用上述下行式双跨移动模架进行施工的方法，该方法包括以下步骤，
步骤一：将每一对牛腿防止在桥墩的两侧，随后通过连接板连接，使牛腿贴紧在桥墩上，随后将推进平车吊放在牛腿顶部并安装；
步骤二：将两个主梁依次吊放在推进平车顶部，并将推进平车上的横、纵、竖，三个液压部分与主梁和牛腿相连接，随后将每组横梁吊放到两个主梁之间，接着将外模板吊放到横梁顶部，并将外模板固定在主梁顶部；
步骤三：最后将斜杆端部连接在对应的外模板底部，通过推进平车上的液压设备使外模板两部分合龙，最后将两个横梁通过螺栓进行固定，并将移动杆拉动，使移动杆的双头端分别插入到同一对的两个横梁内；
步骤四：钢筋在钢筋加工厂进行加工捆扎，随后运输并吊放到外模板顶部，最后进行混凝土的浇筑，最后待混凝土凝固后，通过推进平车，将外模板脱模，并将横梁和外模板拆卸，通过推进平车运输至下一段施工位，将外模板重新合龙固定即可。
本发明的技术效果和优点：
1、本发明通过贴紧连接装置的设置，在推进平车上的液压设备使外模板两部分合龙后，可同时对同一对的两个横梁进行固定，并且贴紧连接装置的顶部嵌入到外模板的连接处，连接处的空隙无法上下贯通，防止发生连续泄漏的情况，提高了安全性；
2、本发明通过垂直于横杆的风将所有的圆台帽向横梁处推动，因此圆台帽会带动插杆插入到横梁内部，进而提高移动杆的稳定性，在风停止后，回位弹簧带动圆台帽自动回到原位，无需后续人员移出，提高了便利性，在有风沿横杆的长度方向吹动时，能够使相对应的圆台帽向横梁处移动，保证上述效果；
3、本发明通过挡环的存在，保证与风有较多的接触面积，使相应的圆台帽向横梁处移动，并且在较大的风的情况下，其表面的扇叶槽能够起到导风的作用，降低风对挡环的推动效果，防止较大的风吹动圆台帽时，造成插杆与横梁的撞击力过大。

在本发明的描述中，需要理解的是，术语“长度”、“宽度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，在本发明的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
本发明提供了如图1-2所示的一种下行式双跨移动模架，包括主梁1、主鼻梁2、牛腿3、推进平车4、横梁5、外模板6、前吊梁7和后吊梁8，所述主梁1的数量为两个，主梁1通过多对横梁5连接，横梁5两两为一组，其底端通过螺栓连接；所述主鼻梁2固定连接在主梁1两端，牛腿3为三对，分别位于主梁1和主梁1两端的主鼻梁2底部，用于对主梁1和主鼻梁2进行支撑，且每对牛腿3之间通过连接板连接，所述推进平车4滑动连接在牛腿3顶部，前吊梁7和后吊梁8分别位于主梁1两端处的主鼻梁2顶部，对主梁1同一端的两个主鼻梁2进行连接；所述外模板6由对称的两部分组成，且两部分的接触处设置有贴紧连接装置9，外模板6的两部分分别与两个主梁1固定连接。
参照说明书附图2-4，所述贴紧连接装置9包括贴合板91，所述贴合板91嵌入到外模板6的两部分的连接处顶部，贴合板91底部固定连接有多个竖杆92，多个竖杆92底端水平插接有同一个横杆93，横杆93外侧套接有多个斜杆94，多个斜杆94顶端均分的铰接在外模板6的两部分底面处；所述竖杆92底端滑动插接有移动杆95，移动杆95远离竖杆92的一端为双头，且分别插接在同一对的两个横梁5内；贴合板91的厚度趋近于外模板6厚度的一半，贴合板91能够对外模板6的合龙处起到阻挡作用，防止外模板6的接缝处上下贯通，贴合板91两侧与外模板6接触处的缝隙不会上下贯通，因此不会发生混凝土向下泄漏的情况，并且在外模板6合龙后，通过将移动杆95的双头端分别插接在同一对的两个横梁5内，此时外模板6、贴紧连接装置9和横梁5处于完全锁紧的状态，提高了整体的连接稳定性，并且无需再通过螺栓固定横梁5，同时在进行拆卸时，将移动杆95从横梁5内部拔出后，再通过推进平车4带动横梁5相互分离时，在外模板6的两部分的分离作用下，此时贴合板91顶部会向上移动，随后进行移动到下一个工位处，并再次进行合拢时，外模板6合拢的过程中，贴合板91能够自动向下移动并贴合外模板6，使用过程较为便利。
参照说明书附图4，所述移动杆95外侧套接有多个圆台帽10，且相邻两个圆台帽10关于横梁5镜像设置，圆台帽10的大头端固定连接有插杆11，插杆11端部能够插接在横梁5内，且圆台帽10的小头端固定连接有回位弹簧12，回位弹簧12端部固定连接在移动杆95外表面；在有大风天气时，垂直吹在圆台帽10的圆柱面上时，会将所有的圆台帽10向横梁5处推动，因此圆台帽10会带动插杆11插入到横梁5内部，进而提高移动杆95的稳定性，在风停止后，回位弹簧12带动圆台帽10自动回到原位，无需后续人员移出，提高了便利性，在有风沿横杆93的长度方向吹动时，能够使相对应的圆台帽10向横梁5处移动，保证上述效果。
参照说明书附图4-5，所述圆台帽10的小头端转动连接有挡环13，挡环13的直径比圆台帽10的小头端的直径大，且挡环13表面开设有扇叶槽14；在风对圆台帽10的小头端吹动时，由于挡环13的存在，保证与风有较多的接触面积，使相应的圆台帽10向横梁5处移动，并且在较大的风的情况下，其表面的扇叶槽14能够起到导风的作用，降低风对挡环13的推动效果，防止较大的风吹动圆台帽10时，造成插杆11与横梁5的撞击力过大。
参照说明书附图1，所述外模板6顶部边缘处设置有抬升架15，抬升架15为皿字形结构；在下雨天时，防雨布能够搭在抬升架15上。
参照说明书附图1-2，所述横梁5设在两根主梁1之间，为型钢梁桁架结构，在横梁5的中轴线位置一分为二，两端分别与主梁1采用螺栓联结。
参照说明书附图1，所述主鼻梁2分为前后两部分，分别与主梁1两端联结，为三角形钢桁结构，在纵向过孔时起导向及纵向平衡作用。
参照说明书附图6，本发明同时公开了使用上述下行式双跨移动模架进行施工的方法，该方法包括以下步骤，
步骤一：将每一对牛腿3防止在桥墩的两侧，随后通过连接板连接，使牛腿3贴紧在桥墩上，随后将推进平车4吊放在牛腿3顶部并安装；
步骤二：将两个主梁1依次吊放在推进平车4顶部，并将推进平车4上的横、纵、竖，三个液压部分与主梁1和牛腿3相连接，随后将每组横梁5吊放到两个主梁1之间，接着将外模板6吊放到横梁5顶部，并将外模板6固定在主梁1顶部；
步骤三：最后将斜杆94端部连接在对应的外模板6底部，通过推进平车4上的液压设备使外模板6两部分合龙，最后将两个横梁5通过螺栓进行固定，并将移动杆95拉动，使移动杆95的双头端分别插入到同一对的两个横梁5内；
步骤四：钢筋在钢筋加工厂进行加工捆扎，随后运输并吊放到外模板6顶部，最后进行混凝土的浇筑，最后待混凝土凝固后，通过推进平车4，将外模板6脱模，并将横梁5和外模板6拆卸，通过推进平车4运输至下一段施工位，将外模板6重新合龙固定即可。
本发明工作原理：由于现有的移动模架需要进行合龙，合龙处需要进行固定，因此此处的强度决定整个工程的安全性，在进行合龙时，对横梁5通过螺栓进行固定，固定繁琐，同时外模板6的合龙处处于横梁5顶部，由于此处缝隙上下贯通，当发生泄漏时，容易造成连续性泄漏，影响浇筑的安全性，因此本发明主要解决的是如何在对横梁5进行固定时，降低固定的繁琐性，并且提高外模板6合龙处的紧密型，进而提高浇筑的安全性；具体采取的措施及使用过程如下：将每一对牛腿3防止在桥墩的两侧，随后通过连接板连接，使牛腿3贴紧在桥墩上，随后将推进平车4吊放在牛腿3顶部并安装，将两个主梁1依次吊放在推进平车4顶部，并将推进平车4上的横、纵、竖，三个液压部分与主梁1和牛腿3相连接，随后将每组横梁5吊放到两个主梁1之间，接着将外模板6吊放到横梁5顶部，并将外模板6固定在主梁1顶部，通过贴紧连接装置9的设置，在推进平车4上的液压设备使外模板6两部分合龙后，可同时对同一对的两个横梁5进行固定，并且贴紧连接装置9的顶部嵌入到外模板6的连接处，连接处的空隙无法上下贯通，防止发生连续泄漏的情况，提高了安全性，组装完成后，将钢筋在钢筋加工厂进行加工捆扎，随后运输并吊放到外模板6顶部，最后进行混凝土的浇筑，最后待混凝土凝固后，通过推进平车4，将外模板6脱模，并将横梁5和外模板6拆卸，通过推进平车4运输至下一段施工位，将外模板6重新合龙固定即可。
尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。。
