Then, the horizontal rod is supported at a predetermined height by the upper end of the screw shaft, and the horizontal beams to which the upper ends of the lath wire mesh are fixed are fixed to both ends of the horizontal rod by a method such as nailing. It can be hung on both the left and right sides of a steel structure. Furthermore, when a crosspiece for hanging a lath wire mesh is nailed to the end of the horizontal rod, the rotation preventing portion prevents the connecting member from rotating inwardly with respect to the main reinforcement, so that the horizontal rod is not screwed. There is no possibility of turning the shaft and connecting member in the nailing direction.

At the same time as fitting, the receiver is supported by the seat 9, and after adjusting the height and horizontality of the horizontal rod 11 by adjusting the height of the seat 9, the nut 10 is screwed onto each screw shaft 8 and the horizontal rod 11 is fixed. are fixed to both screw shafts 8. Next, the crossbars 14 from which the lath wire mesh 13 is hung are fixed to both ends of the crossbars 11 using nails 18, respectively, and the pair of left and right connecting members 1 that support the same crossbar 11 via the screw shaft 8 are rotated. The stop portion 5 comes into contact with the hoop muscle 17 and prevents the horizontal rod 11 from rotating to either the left or right side together with the screw shaft 8 and the connecting member 1, so that the horizontal rod 14
The structure of the connecting member 1 is not limited, although the horizontal rod 11 does not swing in the nailing direction during the nailing operation. For example, as shown in FIG. 4, a clay wall portion 20 to which a nut 7 is welded perpendicularly inward from the upper end of a plate material 19 bent into a substantially J shape.
A laterally opening fitting hole 4 is formed between the upper wall portion 20 and the lower end bent portion 21 of the plate material 19, and a plate material 22 is provided below the lower end bent portion 21 and projects from both left and right sides. are fixed by welding, and both left and right ends of this plate material 22 can be used as the rotation stopping portions 5. In addition, although the nut 7 was used as the vertically penetrating screw hole through which the screw shaft 8 is threaded, if the plate thickness of the connecting member 1 is sufficient, it is also possible to directly machine the screw hole, or if the plate thickness is thin. Even in this case, a cylindrical portion may be provided by burring, and a threaded groove may be formed on the inner periphery of this cylindrical portion to form a threaded hole.
