POST-INSTALLED CONCRETE ANCHOR WITH SHEAR REINFORCEMENT

摘要

A shear performance reinforced post-installed concrete anchor is disclosed. The present invention provides a shear performance reinforcing post-installed concrete anchor which is used as a grouted anchor for attaching an adherend to a hard concrete, has a screw groove formed on an outer circumferential surface along a longitudinal direction thereof,; A first female screw member which is screwed with the anchor rod and inserted into the hole of the hardened concrete; And a second female screw member that is screwed to the anchor rod on the other end side of the anchor rod with respect to the first female screw member and relatively rotates in a direction opposite to the first female screw member to form an interfitting force with each other, And the second female screw member absorb the shear force formed around the joint surface between the hardened concrete and the attachment. According to the present invention, by providing an anchor rod having no tofu, it is possible to reduce the piercing diameter of the toothed bolt, thereby improving workability of the piercing work and suppressing cracking of the concrete, And the shear performance reinforcing after-installation concrete anchor which is made to improve the resistance against the combined forces of both.;
