Split bolt assembly and fastening fastener thereof

TANG FANGFANG

The invention provides a split bolt assembly which comprises a mounting sleeve, limiting sleeves are fixedly connected to the two ends of the mounting sleeve, and two mounting holes are formed in the mounting sleeve. According to the split bolt assembly and the fastening fastener thereof, after a fixing rod is mounted in a mounting hole, a fixing sleeve is mounted on the surface of the fixing rod, and after the fixing rod is inserted into a fixing hole which is formed in a template and matched with two fixing blocks connected with the fixing sleeve, the fixing rod rotates towards one side, so that the fixing sleeve is fixed to the surface of the fixing rod; the two fixing blocks rotate towards one side to a proper position, the two fixing blocks preliminarily limit the fixing rod, meanwhile, after the mounting sleeve is loosened, due to limiting of the two fixing blocks, the mounting sleeve and the fixing rod cannot deviate downwards, and therefore a template on the other side can be conveniently mounted; and meanwhile, after the template is placed at a proper position, the other fixing rod is convenient to mount, so that the mounting efficiency is improved.

本发明提供一种对拉螺栓总成，包括：安装套，安装套的两端均固定连接有限位套，两个安装孔均设置于安装套的内部。本发明提供一种对拉螺栓总成及其紧固扣件，通过将固定杆安装到安装孔的内部后，将固定套安装到固定杆的表面，在通过将固定杆插入模板内部开设与固定套连接着两个固定块相适配的固定孔的内部后，在向一侧进行转动，从而使两个固定块向一侧进行转动到合适的位置后，两个固定块对固定杆进行初步限位，同时在松开安装套后由于两个固定块的限位，使安装套和固定杆不会向下进行偏移，从而方便对另一侧的模板进行安装，同时也在模板放置到合适的位置后，也方便另一个固定杆的安装，从而增加安装效率。
