Description

T型或L型装配式墙体纵向钢混凝土组合管构件 技术领域
 本发明属于装配式建筑技术领域，具体涉及一种T型或L型装配式墙体纵向钢混凝土组合管构件。
 背景技术
 目前，装配式建筑所采用的钢混凝土组合管已经在工程中应用，其中在T型装配式墙体通常包括横向钢混凝土组合管构件和纵向钢混凝土组合管构件，横向钢混凝土组合管构件的中间后侧与纵向钢混凝土组合管构件的前端连接，现有的竖向钢混凝土组合管在实际工程中还存在以下问题：
1、在工厂制作时，在两块薄钢板上先打若干个穿孔，然后将栓拉筋穿入两块薄钢板之间对应的穿孔内，栓拉筋与穿孔紧配合，对两块薄钢板之间的矩形腔进行现场浇筑时，由于振动棒要对混凝土振实，因此时常出现两块薄钢板向外胀，使预制的外部混凝土产生裂纹，影响墙体施工质量。
 2、两块钢板前侧竖向设置有一根槽钢，后侧竖向设有一根H型钢，H型钢前端与横向钢混凝土组合管构件连接，H型钢后端和槽钢前端的开口相对设置，在工厂制作时，槽钢前端向两块薄钢板后侧敞口移动，H型钢后端向两块薄钢板前侧敞口移动，槽钢和H型钢的两侧板会与薄钢板边沿产生对应顶压，影响槽钢和H型钢顺利推入到两块薄钢板内部，影响工厂作业装配效率。
 3、槽钢外侧的栓钉焊接在槽钢上，影响栓钉的连接强度和此处外部混凝土的可靠性。
 发明内容
 本发明为了解决现有技术中的不足之处，提供一种两块薄钢板之间连接强度高，易于安装槽钢及H型钢、与槽钢连接的栓钉及外部混凝土强度和稳定性大大提高的的T型或L型装配式墙体纵向钢混凝土组合管构件。
 为解决上述技术问题，本发明采用如下技术方案：T型或L型装配式墙体纵向钢混凝土组合管构件，包括均竖向设置的槽钢、H型钢和两块薄钢板，两块薄钢板左右间隔设置，槽钢和H型钢前后相对设置，槽钢敞口侧朝前，槽钢前侧伸入设置在两块薄钢板后侧端口内，H型钢后侧伸入设置在两块薄钢板前侧端口内，槽钢、H型钢和两块薄钢板形成矩形钢管结构，两块薄钢板之间通过若干条均沿左右方向布置的栓拉筋连接，栓拉筋左、右端分别向外凸出于左侧、右侧薄钢板表面，槽钢均沿高度方向间隔布置若干条栓钉，每条栓钉均沿前后方向水平设置，栓拉筋两端和栓钉外端固定设有合围成U型的钢丝网，矩形钢管结构外部浇筑混凝土，H型钢前侧、两块薄钢板前侧边和钢丝网前部左右两边均向前伸出外部混凝土，栓拉筋采用钻孔锥丝螺杆，钻孔锥丝螺杆垂直钻入两块薄钢板并与两块薄钢板螺纹连接，钻孔锥丝螺杆包括杆部和大于杆部最大外径的头部，相邻两条钻孔锥丝螺杆的头部分别位于矩形钢管结构的左侧和右侧。
 杆部一端与头部固定连接，杆部自另一端到头部依次为钻头、翻孔圆锥段、尖尾线挤丝螺纹段、光杆段和直螺纹连接段。
 钻头的大端直径等于翻孔圆锥段的小端直径，尖尾线挤丝螺纹段的螺纹小径等于翻孔圆锥段的大端直径；光杆段直径小于或等于尖尾线挤丝螺纹段的螺纹小径；直螺纹连接段的螺纹大径大于尖尾线挤丝螺纹段的螺纹大径；同一根钻孔锥丝螺杆的直螺纹连接段和尖尾线挤丝螺纹段分别与前后两块块薄钢板螺纹连接。
 钢丝网与每条钻孔锥丝螺杆的钻头均通过焊接方式固定连接。
 槽钢两侧边的前侧部左右相对折弯形成第一导向缩口结构，H型钢两侧边的后侧部左右相对折弯形成第二导向缩口结构。
 栓钉采用梯形螺纹杆，槽钢上开设有前后通透的穿孔，梯形螺纹杆穿过穿孔并与穿孔紧配合，梯形螺纹杆前端伸入到矩形钢管结构内部并螺纹连接有前螺母，梯形螺纹杆后端螺纹连接有后螺母，后螺母与钢丝网通过焊接方式连接为一体。
 H型钢的腹板上开设有若干个前后通透的透浆孔，若干个透浆孔沿高度方向均匀间隔布置，H型钢的两块侧板的前侧边均焊接有一条连接板，两条连接板上均开设有若干个安装孔， H型钢的两块侧板的前侧部均开设有与同侧安装孔对应连通的扳手操作孔。
 采用上述技术方案，本发明具有以下技术效果：
1、栓拉筋采用钻孔锥丝螺杆，在向两块薄钢板钻入钻孔锥丝螺杆时，两块薄钢板均水平设置，两块薄钢板的间距固定，打钉装置夹持住钻孔锥丝螺杆的头部驱动杆部旋转，杆部下端的钻头先对上层的薄钢板进行钻孔，接着翻孔圆锥段对钻出的小孔的孔壁向下挤压，使孔壁向下翻出上层的薄钢板下表面，孔的长度大于薄钢板的厚度，翻孔圆锥段进行翻孔延长孔的长度后，尖尾线挤丝螺纹段进入孔内（简称挤丝），将孔壁挤出内螺纹，直到尖尾线挤丝螺纹段上端穿过孔的下端口，接着光杆段穿过具有挤出内螺纹的孔，最后直螺纹连接段下端开开始拧入到内螺纹的孔内，与此同时，钻头向下移动对下层的薄钢板进行钻孔，接着翻孔圆锥段对下侧的薄钢板上钻出的小孔的孔壁向下挤压，使孔壁向下翻出下层的薄钢板下表面，孔的长度大于薄钢板的厚度，翻孔圆锥段进行翻孔延长孔的长度后，尖尾线挤丝螺纹段进入孔内，直到头部上端到上层的薄钢板上表面的距离等于钻头下端到下层的薄钢板下表面的距离，停止钻进，此时尖尾线挤丝螺纹段与下层的薄钢板螺纹连接，直螺纹连接段与上层的薄钢板螺纹连接。
 采用上述这种钻孔打钉连接两块薄钢板的方式，将钻孔和穿筋工序合为一起，先钻孔、再翻孔、接着挤丝、最后螺纹连接，简化了操作工序，施工作业更加方便快捷，通过翻孔延长螺纹连接的长度，这样就可大大提高了薄钢板与栓拉筋之间连接的可靠性。通过一半数量的钻孔锥丝螺杆自上向下钻孔，另一半数量的钻孔锥丝螺杆自下向上钻孔，使得两块薄钢板分别与钻孔锥丝螺杆螺纹连接的拉结力保持平衡。尖尾线挤丝螺纹段具有攻丝（挤丝）的功能，同时与直螺纹连接段均具有与钻出的孔螺纹连接、拉结两块薄钢板的作用。
 2、钢丝网与每条钻孔锥丝螺杆的钻头以及栓钉外端的外螺母焊接，不用绑扎，提高固定连接的可靠性。
 3、在工厂制作钢混凝土组合管时，将两块水平设置的薄钢板通过若干栓拉筋连接为一体后，再将槽钢和H型钢安装到两块薄钢板的左右两侧之间，为了方便槽钢的敞口侧移入到两块薄钢板之间，避免与薄钢板产生顶压，因此将槽钢的敞口侧设置缩口导向结构，这样不仅在允许误差范围内确保槽钢的顺利装配，而且具有提高槽钢自身强度的作用。
 4、栓钉加长，内端伸入到矩形钢管结构内部，并设置前螺母，在矩形钢管结构内部浇筑混凝土后，前螺母可提高轴向锚固效果，使外部混凝土具有良好的稳定性和可靠性。栓钉采用梯形螺纹杆，混凝土在浇筑时可进入梯形螺纹杆的梯形螺纹槽内，进一步提高锚固效果。
 5、H型钢前侧的两块侧板的前侧边焊接的连接板与横向钢混凝土组合管构件的中间后侧对接，横向钢混凝土组合管构件中向后伸出的螺杆穿过连接板上的安装孔，使用紧固螺母螺纹连接在螺杆上，并使用扳手伸入到扳手操作孔内卡住紧固螺母将连接板与横向钢混凝土组合管构件后侧紧固连接。H型钢前侧、两块薄钢板前侧边和钢丝网前部左右两边向前伸出外部混凝土的部分在现场进行浇筑混凝土，透浆孔H型钢腹板前后两侧的现场浇筑的混凝土连接为一体。
 综上所述，本发明与横向钢混凝土组合管构件连接更加方便且强度高，也提高了两块薄钢板之间的拉结效果，确保在浇筑内部混凝土时不会出现薄钢板外胀情况，同时提高槽钢和H型钢的强度，方便两块薄钢板之间的对接，延长栓钉长度，提高内外混凝土的连接的一体性能。

 实施方式
 如图1-图5所示，本发明的T型或L型装配式墙体纵向钢混凝土组合管构件，包括均竖向设置的槽钢1、H型钢17和两块薄钢板2，两块薄钢板2左右间隔设置，槽钢1和H型钢17前后相对设置，槽钢1敞口侧朝前，槽钢1前侧伸入设置在两块薄钢板2后侧端口内，H型钢17后侧伸入设置在两块薄钢板2前侧端口内，槽钢1、H型钢17和两块薄钢板2形成矩形钢管结构，两块薄钢板2之间通过若干条均沿左右方向布置的栓拉筋3连接，栓拉筋3左、右端分别向外凸出于左侧、右侧薄钢板2表面，槽钢1均沿高度方向间隔布置若干条栓钉4，每条栓钉4均沿前后方向水平设置，栓拉筋3两端和栓钉4外端固定设有合围成U型的钢丝网5，矩形钢管结构外部浇筑混凝土，H型钢17前侧、两块薄钢板2前侧边和钢丝网5前部左右两边均向前伸出外部混凝土6，栓拉筋3采用钻孔锥丝螺杆，钻孔锥丝螺杆垂直钻入两块薄钢板2并与两块薄钢板2螺纹连接，钻孔锥丝螺杆包括杆部和大于杆部最大外径的头部7，相邻两条钻孔锥丝螺杆的头部7分别位于矩形钢管结构的左侧和右侧。
 杆部一端与头部7固定连接，杆部自另一端到头部7依次为钻头8、翻孔圆锥段9、尖尾线挤丝螺纹段10、光杆段11和直螺纹连接段12。
 钻头8的大端直径等于翻孔圆锥段9的小端直径，尖尾线挤丝螺纹段10的螺纹小径等于翻孔圆锥段9的大端直径；光杆段11直径小于或等于尖尾线挤丝螺纹段10的螺纹小径；直螺纹连接段12的螺纹大径大于尖尾线挤丝螺纹段10的螺纹大径；同一根钻孔锥丝螺杆的直螺纹连接段12和尖尾线挤丝螺纹段10分别与前后两块块薄钢板2螺纹连接。
 钢丝网5与每条钻孔锥丝螺杆的钻头8均通过焊接方式固定连接。
 槽钢1两侧边的前侧部左右相对折弯形成第一导向缩口结构13，H型钢17两侧边的后侧部左右相对折弯形成第二导向缩口结构14。
 栓钉4采用梯形螺纹杆，槽钢1上开设有前后通透的穿孔，梯形螺纹杆穿过穿孔并与穿孔紧配合，梯形螺纹杆前端伸入到矩形钢管结构内部并螺纹连接有前螺母15，梯形螺纹杆后端螺纹连接有后螺母16，后螺母16与钢丝网5通过焊接方式连接为一体。
 H型钢17的腹板上开设有若干个前后通透的透浆孔18，若干个透浆孔18沿高度方向均匀间隔布置，H型钢17的两块侧板的前侧边均焊接有一条连接板19，两条连接板19上均开设有若干个安装孔20， H型钢17的两块侧板的前侧部均开设有与同侧安装孔20对应连通的扳手操作孔21。
 本发明具有以下技术效果：
1、栓拉筋3采用钻孔锥丝螺杆，在向两块薄钢板2钻入钻孔锥丝螺杆时，两块薄钢板2均水平设置，两块薄钢板2的间距固定，打钉装置夹持住钻孔锥丝螺杆的头部7驱动杆部旋转，杆部下端的钻头8先对上层的薄钢板2进行钻孔，接着翻孔圆锥段9对钻出的小孔的孔壁向下挤压，使孔壁向下翻出上层的薄钢板2下表面，孔的长度大于薄钢板2的厚度，翻孔圆锥段9进行翻孔延长孔的长度后，尖尾线挤丝螺纹段10进入孔内（简称挤丝），将孔壁挤出内螺纹，直到尖尾线挤丝螺纹段10上端穿过孔的下端口，接着光杆段11穿过具有挤出内螺纹的孔，最后直螺纹连接段12下端开开始拧入到内螺纹的孔内，与此同时，钻头8向下移动对下层的薄钢板2进行钻孔，接着翻孔圆锥段9对下侧的薄钢板2上钻出的小孔的孔壁向下挤压，使孔壁向下翻出下层的薄钢板2下表面，孔的长度大于薄钢板2的厚度，翻孔圆锥段9进行翻孔延长孔的长度后，尖尾线挤丝螺纹段10进入孔内，直到头部7上端到上层的薄钢板2上表面的距离等于钻头8下端到下层的薄钢板2下表面的距离，停止钻进，此时尖尾线挤丝螺纹段10与下层的薄钢板2螺纹连接，直螺纹连接段12与上层的薄钢板2螺纹连接。
 采用上述这种钻孔打钉连接两块薄钢板2的方式，将钻孔和穿筋工序合为一起，先钻孔、再翻孔、接着挤丝、最后螺纹连接，简化了操作工序，施工作业更加方便快捷，通过翻孔延长螺纹连接的长度，这样就可大大提高了薄钢板2与栓拉筋3之间连接的可靠性。通过一半数量的钻孔锥丝螺杆自上向下钻孔，另一半数量的钻孔锥丝螺杆自下向上钻孔，使得两块薄钢板2分别与钻孔锥丝螺杆螺纹连接的拉结力保持平衡。尖尾线挤丝螺纹段10具有攻丝（挤丝）的功能，同时与直螺纹连接段12均具有与钻出的孔螺纹连接、拉结两块薄钢板2的作用。
 2、钢丝网5与每条钻孔锥丝螺杆的钻头8以及栓钉4外端的外螺母焊接，不用绑扎，提高固定连接的可靠性。
 3、在工厂制作钢混凝土组合管时，将两块水平设置的薄钢板2通过若干栓拉筋3连接为一体后，再将槽钢1和H型钢17安装到两块薄钢板2的左右两侧之间，为了方便槽钢1的敞口侧移入到两块薄钢板2之间，避免与薄钢板2产生顶压，因此将槽钢1的敞口侧设置缩口导向结构，这样不仅在允许误差范围内确保槽钢1的顺利装配，而且具有提高槽钢1自身强度的作用。
 4、栓钉4加长，内端伸入到矩形钢管结构内部，并设置前螺母15，在矩形钢管结构内部浇筑混凝土后，前螺母15可提高轴向锚固效果，使外部混凝土6具有良好的稳定性和可靠性。栓钉4采用梯形螺纹杆，混凝土在浇筑时可进入梯形螺纹杆的梯形螺纹槽内，进一步提高锚固效果。
 5、H型钢17前侧的两块侧板的前侧边焊接的连接板19与横向钢混凝土组合管构件的中间后侧对接，横向钢混凝土组合管构件中向后伸出的螺杆穿过连接板19上的安装孔20，使用紧固螺母螺纹连接在螺杆上，并使用扳手伸入到扳手操作孔21内卡住紧固螺母将连接板19与横向钢混凝土组合管构件后侧紧固连接。H型钢17前侧、两块薄钢板2前侧边和钢丝网5前部左右两边向前伸出外部混凝土6的部分在现场进行浇筑混凝土，透浆孔18H型钢17腹板前后两侧的现场浇筑的混凝土连接为一体。
 本实施例并非对本发明的形状、材料、结构等作任何形式上的限制，凡是依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均属于本发明技术方案的保护范围。
