Description

套筒外螺母卡接式连接装置及其连接结构及其安装方法 技术领域
本发明涉及墙体连接结构，特别涉及一种套筒外螺母卡接式连接结构。
背景技术
目前，装配式混凝土结构建筑，预制构件的连接方法，特别是竖向构件(预制墙板/柱)的竖向钢筋连接方式主要有：1)预埋件焊接连接、2)预埋件螺栓连接、3)钢筋套筒灌浆连接三种连接方式。
1)预埋件焊接连接是连接钢板预置在构件连接部位，预制构件安装就为后，将构件间相邻的预埋钢板焊接连接成一体的方式连接。
优点：安装操作简单；缺点:因焊接工艺原因使连接钢板性能发生脆性改变，造成钢板韧性差/易开裂/连接强度低、结构连接整体性/气密性/抗震性差、防腐/耐久性差；现在属于淘汰技术，市场应用范围小。
2)预埋件螺栓连接方法是将预埋钢板预留螺栓孔，并在安装部位预留安装螺栓，预置构件安装时将预留螺栓插入预置构件的预埋钢板的螺栓孔内用螺母紧固。优点是连接强度比焊接强度高、缺点：成本高、结构连接整体性/气密性/抗震性差、防腐/耐久性差；市场应用范围小。
3)钢筋套筒灌浆连接：如图5和图6所示，灌浆套筒包括两端开口的套筒和安装在套筒侧壁上的进浆口51和出浆口52。套筒预埋在上部构件53中，上部构件的预埋筋54插入套筒内，套筒进浆口和出浆口预留在上部构件的外侧。安装时，下部构件55凸出的连接筋56插入套筒内；构件安装定位后，将上部构件和下部构件的接缝57进行填塞，然后从进浆孔注入灌浆料，使钢筋与套筒结合，起到连接作用。
优点：连接钢筋插入套筒后通过灌浆使钢筋处于密封环境解决了
防腐/耐久性问题、连接强度优于以上焊接和栓接的两种方式。
缺点：实际应用中，钢筋套筒灌浆连接技术存在以下问题需要改进：1.受钢筋变形、位移、安装间隙小等因素影响施工操作难度大；2.漏浆问题容易发生且无法质检；3.操作工艺复杂，需要专用设备、工具、材料、人员；4.成本高、质量难以控制；4.影响灌浆料质量的因素多(材料、水灰比、搅拌、注浆、漏浆、人员操作、应用时间等)，质量控制难度大；5.由于钢筋套筒灌浆连接技术是通过灌浆料将钢筋与套筒粘合，利用摩擦力原理与作用实现的钢筋连接。所以灌浆料作为连接介质，起到了连接质量的决定性作用，必须灌浆饱 满、无漏浆、无收缩，但是，实际应用过程中特别是竖向构件连接(容易漏浆、且无法质检)很难保证连接质量，质量可控性差；连接质量的好坏直接影响钢筋的连接强度，形成无效连接(钢筋抽芯现象)，造成建筑安全隐患。
另外，即使在钢筋套筒灌浆连接质量没有问题的情况下，结构连接也存在着一个无法解决的技术问题：竖向混凝土预制构件结构连接整体性问题，也就是预制构件底部与叠合板现浇层间的水平连接缝问题。因为竖向预制构件安装时构件底部的砂浆(粘合/找平层)强度与低于预制构件混凝土强度，造成受力点薄弱，影响混凝土结构的整体性差，抗震性低的问题。
发明内容
本发明的目的是提供一种套筒外螺母卡接式连接装置及其连接结构及其安装方法，其优点是可以提高连接钢筋与套筒之间的连接强度，且便于安装。

通过上述技术方案，需要对两个墙体相互靠近的端面进行连接时，可将杆状连接件固定在墙体上，然后再从通孔插入套筒内部，向套筒内部浇筑水泥浆并待水泥浆凝固之后，可将杆状件和套筒固定连接在一起，由于通孔的内径小于套筒端口的内径，凝固的水泥浆受到朝拔出套筒方向的作用力之后，限位板可对凝固的水泥浆进行支撑，限制水泥浆脱离套筒，提高套筒对墙体的连接强度。
本发明进一步设置为：还包括卡块，卡块上开设有插接孔，卡块可沿径向拆分为两半；卡块可从所述套筒的端部插入套筒内部，卡块插入套筒内部之后，所述通孔的内径小于卡块沿套筒直径方向的尺寸。
本发明进一步设置为：所述卡块一端设有圆台面，卡块插入套筒之后，圆台面较小的一端朝向拔出套筒的方向。
本发明进一步设置为：所述圆台面较小的一端外径小于所述通孔的内径，通孔的内径小于圆台面较大的一端的外径。
本发明进一步设置为：所述通孔内壁设有圆锥面，所述外卡接螺母安装在所述套筒上之后，圆锥面较大的一端朝向套筒的中心。
通过上述技术方案，水泥浆凝固之后，卡块受到朝拔出套筒方向的作用力之后，圆台面挤压凝固的水泥浆，对水泥浆产生朝远离套筒中心轴线方向的作用力，减小轴向力的集中，使作用力更加分散。
一种套筒外螺母卡接式连接结构，采用上述的套筒外螺母卡接式连接装置，套筒外螺母卡接式连接结构包括套筒外螺母卡接式连接装置和连接钢筋，连接钢筋端部固定连接有扩大头，所述扩大头的外径小于所述通孔的内径。
通过上述技术方案，水泥浆凝固之后，扩大头可提高连接钢筋与混凝土之间的连接强度，进而提高连接钢筋与套筒之间的连接强度，从而提高外螺母卡接式套筒的连接结构对墙体的连接强度；扩大头可穿过通孔插入套筒内部，便于安装。
一种外螺母卡接式套筒连接结构的安装方法，包括以下步骤：
S1：将外卡接螺母套在连接钢筋上；
S2：将连接钢筋插入套筒内部；
S3：将外卡接螺母与套筒相螺纹连接。
本发明进一步设置为：所述S1还包括步骤A1：先将卡块拆分为两部分，再将两部分卡块拼合套接在连接钢筋上，使卡块位于外卡接螺母和扩大头之间。
综上所述，本发明具有以下有益效果：
1、连接钢筋插接在套筒内部后，向套筒内部浇筑水泥浆，水泥浆凝固之后可将套筒与连接钢筋固定连接在一起，提高连接钢筋与套筒之间的连接强度；
2、将外卡接螺母套接在连接钢筋上，将连接钢筋插接在套筒内部之后，再将外卡接螺母螺纹固定连接在套筒的端部，扩大头朝拔出套筒的方向运动时可与限位板相抵接，限制连接钢筋拔出套筒，提高套筒与连接钢筋之间的连接强度；
3、注浆孔便于水泥浆流入套筒内部，使套筒内部填充的水泥浆更加饱满，提高水泥浆凝固后与套筒之间的连接强度；
4、圆台面和圆锥面均可将轴向的作用力向径向分散，减小轴向受力集中，提高套筒与连接钢筋之间的连接强度。
