8-shaped anti-shearing steel bar and steel corbel structure for jacking and mounting method of 8-shaped anti-shearing steel bar and steel corbel structure
The invention discloses an 8-shaped anti-shearing steel bar and steel corbel structure for jacking and a mounting method. The 8-shaped anti-shearing steel bar and steel corbel structure comprises an upper corbel device, a steel slide way device, an anti-shearing steel bar, a pull rod, an anti-shearing steel bar bolt, a concrete column of a jacked building and an embedded part. The upper brackets are hinged to the concrete column through the 8-shaped anti-shearing steel bars and the anti-shearing steel bar bolts, the steel slide way devices are connected with the concrete column through the self-locking anchor rods or the embedded steel bars, the pull rods enable the two upper brackets of the single column to be connected into a whole, and the overall rigidity is better. The concrete column embedded part reinforces the 8-shaped hole of the concrete column, and concrete damage caused by overlarge local compressive stress of the 8-shaped shear-resistant steel bar on concrete around the 8-shaped hole of the concrete column is avoided. The anti-shearing steel bar bolt is provided with two circles of spiral solid bodies, after the anti-shearing steel bar bolt is inserted into the 8-shaped anti-shearing steel bar bolt hole, the middle of the anti-shearing steel bar bolt rebounds to abut against the inner wall of the anti-shearing steel bar bolt hole through the elastic force of the bolt, and the 8-shaped anti-shearing steel bar is effectively prevented from sliding in the hole channel to cause safety influence.
本发明公开了一种顶升用8字形抗剪钢棒和钢牛腿结构及安装方法，包括上牛腿装置、钢滑道装置、抗剪钢棒及拉杆、抗剪钢棒插销和被顶升建筑物的混凝土柱及埋件。上牛腿通过8字形抗剪钢棒、抗剪钢棒插销与混凝土柱铰接连接，钢滑道装置通过自锁锚杆或植筋与混凝土柱连接，拉杆使得单柱两上牛腿连成整体，整体刚度更好。混凝土柱预埋件对混凝土柱8字形孔进行补强，避免8字形抗剪钢棒对混凝土柱8字形孔周边混凝土局部压应力过大而出现混凝土破损。抗剪钢棒插销有两圈螺旋状实体，插入8字形抗剪钢棒插销孔后插销弹力使得抗剪钢棒插销中部反弹顶住抗剪钢棒插销孔处内壁，有效阻止8字形抗剪钢棒在孔道内滑动而出现安全影响。
