Description

一种滑模纠偏纠扭调节体系及其使用方法 技术领域
本发明涉及一种建筑施工技术领域，特别是一种滑模纠偏纠扭调节体系及其使用方法。
背景技术
滑模也称滑动模板，是现浇混凝土结构工程施工中一种机械化程度较高的工具式模板。这种模板已经广泛用于贮仓、水塔、烟囱、桥墩、进水塔、立井井壁、边墙、尾水闸墩等断面竖向结构的施工，而且已经发展用于高层和超高层民用建筑的竖向结构施工。滑模施工有以下优点：
1、不设水平施工缝，施工连续性好；
2、施工进度快，日平均滑升2.5m左右，立模浇筑无法比拟；
3、工作盘形成后，辅助性材料消耗少；
4、混凝土表面平整度高，外观质量好，混凝土缺陷处理工作量小。
滑模施工时，在成组液压千斤顶的同步作用下，在固定于墙面的支撑杆爬升，并带动1米多高的工具式模板或滑框沿着刚成型的混凝土表面或模板表面滑动，混凝土由模板的上口分层向套槽内浇灌，当模板内最下层的混凝 土达到一定强度后，沿着已浇灌的混凝土表面滑动或是滑框沿着模板外表面滑动，这样如此连续循环作业，直到达到设计高度，完成整个施工。
由于支撑杆一端自由，在爬升过程中，平台会因以下因素出现偏扭的情况：
1、个别液压千斤顶行程没有同步或失效。
2、平台物料堆放分布不均，平台不平衡。
3、模板与混凝土面摩擦力分布不均。
滑模平台出现轻微偏扭的情况十分常见，常采用平台倾斜法或平台配重法解决，但实际情况上述两种方案调节效果十分有限，如处理不当，成型结构会出现较大的误差。因此有必要研究一种新的滑模纠偏纠扭体系调节装置来解决上述的技术问题。
发明内容
为了克服上述现有技术的缺陷，本发明的目的是提供一种滑模纠偏纠扭调节体系，通过钢丝绳倒链实现门架之间相互斜拉，依此将滑模体系的所有门架采用这种方式连接在一起，以纠偏纠扭。
本发明的目的在于提供一种滑模纠偏纠扭调节体系，包括：
门架以及钢丝绳倒链(1)，每一个所述门架与相邻的第二个门架通过所述钢丝绳倒链(1)连接，每隔一个门架，两个门架之间相互斜拉，依此将滑模体系的所有门架采用这种方式连接在一起；其中，所述门架包括门架腿(2)、门架上横梁(3)、门架下横梁(4)、围檩卡耳(5)以及门架吊框(6)， 其中在平面上竖直设置多条平行的所述门架腿(2)，所述门架上横梁(3)以及所述门架下横梁(4)垂直所述门架腿(2)分别跨接设置在所述门架腿(2)的上下两侧，所述围檩卡耳(5)设置在所述门架吊框(6)一边内侧的上下两端或所述围檩卡耳(5)设置在所述门架吊框(6)两边内侧的上下两端。
优选的，所述钢丝绳倒链(1)固定在所述门架上横梁(3)和另一个门架的所述围檩卡耳(5)上，从而每个所述门架在两侧分别固定两道所述钢丝绳倒链(1)。
优选的，所述门架上横梁(3)的宽度比所述门架下横梁(4)宽度大。
优选的，所述门架上横梁(3)的宽度等于所述门架下横梁(4)的宽度。
优选的，所述围檩卡耳(4)为双层方钢围檩卡耳。
优选的，所述围檩卡耳(4)的截面为方形或圆形。
优选的，所述围檩卡耳(4)的截面为六边形。
优选的，所述门架腿(2)为两条或四条。
优选的，所述钢丝绳倒链(1)的张紧程度通过其上设置的调节钢箍调节，从而控制门架的相对位置。
本发明的目的还在于提供一种滑模纠偏纠扭调节体系的使用方法，包括：
(1)当平台发生顺时针扭转时，收紧所述钢丝绳倒链(1)使所有门架有逆时针倾倒的趋势，随着滑模提升，平台将逐渐恢复原位；
(2)当平台发生逆时针扭转时，将顺偏移方向的门架向反方向调节，平 台便会随着提升而复位。
本发明具有以下有益效果：
本发明可以达到滑模施工时，平台变形可以得到及时快速准确纠偏的效果。
附图说明
图1为根据本发明优选实施例的滑模纠偏纠扭调节体系结构示意图。
其中，1-钢丝绳倒链；2-门架腿2；3-门架上横梁；4-门架下横梁；5-围檩卡耳；6-门架吊框6
具体实施方式
如图1所示，本发明结合具体实施例和附图做进一步说明。
如图1所示，本实施例的滑模纠偏纠扭调节体系，包括：门架以及钢丝绳倒链1，每一个门架与相邻的第二个门架通过钢丝绳倒链1连接，每隔一个门架，两个门架之间相互斜拉，依此将滑模体系的所有门架采用这种方式连接在一起。
其中，门架包括门架腿2、门架上横梁3、门架下横梁4、围檩卡耳5以及门架吊框6，其中在平面上竖直设置多条平行的门架腿2，门架上横梁3以及门架下横梁4垂直门架腿2分别跨接设置在门架腿2的上下两侧，围檩卡耳5设置在门架吊框6一边内侧的上下两端。钢丝绳倒链1固定在门架上 横梁3和另一个门架的围檩卡耳5上，从而每个门架在两侧分别固定两道钢丝绳倒链1。
通常设计为门架上横梁3的宽度比门架下横梁4宽度大，并于倒链斜拉，当然，也可以设置为门架上横梁3的宽度等于门架下横梁4宽度。本实施例中，围檩卡耳4制作为双层方钢围檩卡耳。围檩卡耳4的截面为方形或圆形，其中方形截面情况下拉紧的固定程度优于圆形截面的情况，当然本领域技术人员也可以根据需要设置其他多边形截面形式，如六边形，从而使得钢丝绳倒链1能通过更多的接触面牢牢固定。
作为另一优选实施方式，围檩卡耳5设置在门架吊框6两边内侧的上下两端。从而形成两重调节体系，根据实际工程需求选择任意方便实施的一侧构成调节体系。
门架腿2的数量为偶数，一般为两条或四条。
钢丝绳倒链1的张紧程度通过其上设置的调节钢箍或者其他适当的方式调节，从而控制门架的相对位置。
该滑模纠偏纠扭调节体系的工作原理：
当平台发生顺时针扭转时，收紧钢丝绳倒链1使所有门架有逆时针倾倒的趋势，随着滑模提升，平台将逐渐恢复原位。当平台发生逆时针扭转时，将顺偏移方向的门架向反方向调节，平台便会随着提升而复位。
尽管上文对本发明的具体实施方式给与了详细描述和说明，但是应该指明的是，我们可以依据本发明的构想对上述实施方式进行各种等效改变和修 改，其所产生的功能作用仍未超出说明书所涵盖的精神时，均应在本发明的保护范围之内。
