Glue overflowing and wall breaking type building anchor bolt
The invention discloses a glue overflowing and wall breaking type building anchor bolt, and belongs to the technical field of building anchor bolts. A plurality of glue overflowing bags pre-fill the bottom end wall of an outer screw rod, in the spiral sinking process of an inner screw rod, a plurality of self-heating pieces move downwards along inner closed cavities by virtue of the magnetic attraction effect of a magnetic ring on the self-heating pieces, and the self-heating pieces enable the glue overflowing bags to be jacked, expanded and broken, so that anchoring glue in the glue overflowing bags overflows and is distributed inside and outside the outer screw rod, the outer screw rod and the concrete hole wall are connected in a gluing mode, and extrusion resistance caused by the fact that the anchoring glue is placed in advance does not need to be borne; and meanwhile after self-heating filler in the self-heating pieces automatically generates heat, on one hand, the hot melting effect on the glue overflowing bags and the anchoring glue is achieved, the bonding effect is improved, on the other hand, after the self-heating pieces generate heat, the multiple expansion anchoring nails penetrate through the self-heating pieces and are inserted into the concrete hole wall, and the transverse shear between the outer screw rod and the concrete hole wall is effectively improved and the pulling resistance of the outer screw rod is increased under cooperation of the evenly-distributed anchoring glue.
本发明公开了一种溢胶破壁型建筑锚栓，属于建筑锚栓技术领域，通过将多个溢胶囊包预先填充于外螺杆底端壁上,在内螺杆螺旋下沉过程中，依靠磁环对自热件上的磁吸作用，使得多个自热件沿着内封闭腔向下运动，自热件溢胶囊包进行顶撑胀裂，使得溢胶囊包内的锚固胶溢出并分布于外螺杆的内外部，实现外螺杆与混凝土孔壁之间的胶固连接，无需承受预先放置锚固胶所带来的挤压阻力，同时自热件内的自热填料自主生热后，一方面对溢胶囊包以及锚固胶起到热熔作用，提高粘结效果，另一方面在自热件生热后使得多个膨胀锚固钉贯穿自热件并插设于混凝土孔壁上，配合均匀分布的锚固胶，有效提高了外螺杆与混凝土孔壁之间的横向剪切而增大其抗拔力。
