Description of the Related Art Conventionally, as shown in FIG. 4, a straight mounting hole (2) is formed on the back surface of a wall plate (1), and a split sleeve (3) having a tapered hole is formed in this mounting hole (2). ) And an anchor bolt (4) having a tapered surface that fits into the tapered hole are inserted, and the wall plate (1) is attached to the surface of the foundation (A) of the building structure to which the wall plate (1) is to be attached via the bolt (5). By inserting the anchor bolt (4) into the attached support fitting (6) and tightening the nut (7), the split sleeve (3) is expanded in the mounting hole (2), and the split sleeve (3). The wall plate (1) was attached to the surface of the groundwork (A) of the building structure by crimping the outer peripheral surface of the inside of the attachment hole (2).

い壁板には適用できないという問題点があった。In the conventional mounting structure described above, the moving distance in the axial direction of the bolt due to the tightening of the anchor bolt (4) is the working distance in the direction in which the split sleeve (3) is expanded through the tapered surface. Is converted to
In order to crimp the split sleeve (3) into the mounting hole (2) with a predetermined crimping force, it is necessary to lengthen the axial length of the tapered surface to some extent and deepen the mounting hole (2). However, there is a problem that it cannot be applied to thin wall boards.

が亀裂破損し易い問題点があった。On the other hand, in the conventional mounting structure, the split sleeve (3) is expanded in diameter by the anchor bolt (4) and crimped inside the mounting hole (2), so that the peripheral edge of the bottom portion of the mounting hole (2) is fixed. The tensile stress is concentrated, and the wall plate (1) is introduced from the peripheral portion of the bottom.
However, there was a problem that cracks were likely to occur.

させることが必要となる等の新たな問題点が発生する。In order to solve the above problems, it is necessary to increase the thickness of the wall plate (1), which leads to an increase in the cost of the wall plate (1), and at the same time, when the wall plate (1) is thickened, the wall plate (1) is increased. (1) A new problem arises in that the weight of the whole becomes large and it becomes necessary to improve the rigidity of the supporting member.

題点があった。In the conventional mounting structure, the crimping force of the split sleeve (3) to the mounting hole (2) is adjusted by controlling the tightening torque of the nut (7) with respect to the anchor bolt (4). Variation in the hole diameter of the hole (2), different tightening force of the nut (7) depending on the operator, and variation in the dimensional accuracy of the split sleeve (3) cannot be avoided.
There is a problem that the holding power of the wall plate (1) also varies.

By inserting and screwing and tightening to the nut member, the wall plate can be attracted and fixed to the supporting metal fitting side of the surface of the foundation of the building structure, so tensile stress does not occur in the keyhole-shaped locking groove, The wall board can be easily and surely attached to the surface of the base of the building structure. Further, according to the present invention, the depth of the keyhole-shaped locking groove can be made shallower than in the conventional case in which the anchor bolt is moved in the axial direction to expand the split sleeve, and thus the depth is thin. It can also be applied to wall boards.
