Description
技术领域
本发明涉及装配式建筑技术领域,具体涉及一种装配式墙体间连接节点及其施工方法。
背景技术
装配式墙体在工厂预制,现场进行组配安装,提高施工效率的同时减少了湿式作业,有利于减少建筑垃圾,是一种绿色环保的施工模式,但是现有的装配式墙体的连接方式主要为刚性连接,如通过螺栓连接或者焊接连接,连接节点的抗震性能较差。
目前装配式建筑主要适用于非抗震设计以及抗震设防烈度为6-8度抗震设计地区的乙类以及乙类以下的各类民用建筑,主要原因为节点的构造大都有节点的连接强度不够牢靠,结构整体性不强,抗震性较差,容易造成装配式墙体变形、产生裂缝的缺点,其连接形式也无法满足装配式建筑更高要求的使用功能。
发明内容
为了解决上述存在的技术问题,本发明提供了一种装配式墙体连接节点及其施工方法,主要是为了开发或者探索出一种新型的整体性好、构造简单、安全可靠的装配式墙体连接节点,能够有效的解决施工繁琐、连接不牢固等问题。
本发明采用的技术方案如下:
一种装配式墙体连接节点,其组成包括左侧墙体、右侧墙体、预制空心柱和柱芯,所述的左侧墙体的右端自上而下设置有凸出墙体长度与右侧墙体厚度相同的凸起,凸起在上下方向有矩形的中空,在每个凸起的下侧设置一个内置伸缩弹簧的插栓;所述的右侧墙体的左端自上而下设置有凸出墙体长度与左侧墙体厚度相同的凸起,凸起在上下方向有矩形的中空,凸起的上端为凹槽,在凹槽内为矩形钢筋框,矩形钢筋框与凸起结构内的钢筋连接在一起,矩形钢筋框下端高出槽底,凸起的下端设置有钢筋挂钩4个,在钢筋挂钩的下端设置有2个弯曲架;所述的预制空心柱为中空的四边形柱,在水平方向的外截面尺寸与左侧墙体凸起的中空内截面尺寸一致,预制空心柱设置有4根通长的钢筋,在预制空心柱上端用矩形钢筋框分别与这4根通长钢筋焊接在一起,在预制空心柱的下端通长钢筋外露出预制空心柱,在外露钢筋的下端设置有挂钩,挂钩设置在预制空心柱的转角处,在每两个挂钩下端用短圆钢焊接,短圆钢上设置有弹力板;所述的柱芯为两端为钢结构柱、中间为钢筋混凝土结构的实心柱,两端的钢结构柱与中间的混凝土柱内部的钢筋固定连接,柱芯在水平方向的矩形外截面尺寸与上述的预制空心柱水平方向的矩形内截面尺寸一致,同时与右侧墙体凸起的中空在水平方向截面尺寸一致。
所述的左侧墙体凸起内自下而上设置有3根环绕中空的钢筋,与钢筋混凝土墙体固定连接,最上端的环绕中空的钢筋下面设置有凹槽,凹槽尺寸与右侧墙体凸起下端的4个钢筋挂钩尺寸相对应,最下端及中端的环绕中空的钢筋在左右墙体连接完成后可包围住预制空心柱的上端。
所述右侧墙体凸起上端凹槽内矩形钢筋框的尺寸与预制空心柱下端的弹力板尺寸相对应;右侧墙体凸起下端的4个钢筋挂钩在2个弯曲架的作用下,可以与左侧墙体凸起上端内侧预留的环绕中空的钢筋搭接锚固。
所述的弯曲架组成包括平钢板、转筒、弯钢板,在右侧墙体凸起的下端的钢筋挂钩的下端和挂钩头部均焊接有圆钢筋,转筒套在挂钩下端的圆钢筋上,平钢板一端焊接在转筒上,弯钢板一端焊接在转筒上,另一端焊接在挂钩头部的圆钢筋上,所述的弹力板组成包括中槽转筒、弹力片、梯形钢板,在预制空心柱下端的钢筋挂钩上两两采用圆钢焊接,中槽转筒套在圆钢上,中槽转筒的中间位置沿转筒圆周切有开口,弹力片通过这个开口一端与圆钢焊接,另一端与梯形钢板抵接,梯形钢板焊接在中槽转筒上,一侧与钢筋挂钩的端点位置抵接,一侧与弹力片抵接。
所述的墙体、预制空心柱均为钢筋混凝土材料,柱芯可为钢结构,也可为两端钢结构中间钢筋混凝土材料。
所述的左侧墙体最下侧凸起的上端内侧预埋有注浆接口,接口通过管道连接到墙体内侧便于操作,左侧墙体最上侧凸起的上端内侧预埋有出浆接口,同样连接到墙体内侧,为防止后期压浆时漏浆,可用聚苯乙烯泡沫板或者橡胶等材料做成的密封条贴在左右侧墙体连接缝处;柱芯与柱芯的连接通过插接及4个可滑动实心金属块锁接,4个可滑动实心金属块分别与柱芯4面外壁之间设置压缩弹簧;所述的插接为柱芯的金属柱形凸头与另一柱芯的金属凹槽形状、尺寸均相同,采取插入连接形式;柱芯沿着竖直方向的外壁上设置有上下贯通凹槽,压浆时浆料可以沿凹槽流动。
一种装配式墙体连接节点的施工方法为:将预制空心柱从左侧墙体的凸起中间推入,插栓在推力下被挤入凹槽,预制空心柱从凸起的中空内滑入直至预制空心柱的下端与下端的插栓抵接,被挤入凹槽的插栓在弹簧的弹力下弹出与空心柱的上端抵接,空心柱被固定在左侧墙体上,将右侧墙体的凸起部位与左侧墙体空心柱的下端相对应的凹槽对接平移,待完全对接后,插栓被挤入凹槽,使右侧墙体竖直上提,右侧墙体凸起上端凹槽内钢筋与预制空心柱下端的弹力板挂接,待挂接完成后,竖直下放右侧墙体,在右侧墙体重力作用下带动预制空心柱下滑直至右侧墙体凸起下端与左侧墙体凸起上端抵接,将柱芯插入,柱芯推动弯曲架转动,继而将右侧墙体凸起下端的钢筋挂钩与左侧墙体凸起上端内侧预留的钢筋搭接锚固,柱芯外壁与弹力板抵接,保障挂接的牢固性,柱芯与柱芯插接连接,完成装配式墙体的连接后,从下端注浆口注入水泥浆直至上端出浆口出浆,用橡皮塞塞紧;首层施工时,左侧墙体自下而上第一个凸起的下侧不再设置插栓,预制空心柱从第一个凸起的中空内滑入后向下推至相应位置,下端与建筑物基础结构锚固连接,柱芯下端也与建筑物基础结构锚固连接,其他实施方法步骤与上述一致。
本发明的优点效果:与现有技术相比,其连接过程简洁,无需螺栓等连接后的锚固,便于施工,施工效率高,墙体连接后整体性强,使装配式墙体的抗风抗震能力提高。
