[Prior art]

 Generally, when connecting a handrail headstock and a pillar, the upper end surface of the pillar is cut into a curved surface corresponding to the outer surface of the circular-shaped headpiece, and this curved end surface is engaged with the lower surface of the headstock. On the other hand, with a long bolt for tightening the column standing on the base inserted in the column, the upper end of this bolt is projected from the bolt hole provided in the tree, and the protruding end is used to By connecting the nuts from the side and tightening the nuts, the headstock and the stanchions were connected (note that the nuts are also tightened with the upper mold material forming the headstock removed). However, according to this, there is a problem that it takes a lot of time to form the curved surface of the end face of the support and the material cost is high because the tightening bolt is long.

In order to solve such a problem, conventionally, as this type of connecting device, the inside of one of the upper and lower mold members 101a and 101b forming the lateral member 101 as shown in FIG. The horizontal support wall 102 is provided on the side of the mold, and the opening 101 having a shape corresponding to the cross-sectional shape of the vertical member 103 is provided on the mold material 101b on the side where the horizontal support wall 102 is provided. The pocket 105 is provided over the entire length, and the end of the vertical member 103 is fitted into the opening 104 of the horizontal member 101 so that the end thereof is brought into contact with and supported by the horizontal support wall 102. There is one in which a screw 106 is inserted from the side opposite to the contacting end of the vertical member 103 and screwed into the screw pocket 105 of the vertical member 103. This eliminates the troublesome work of cutting the end portion of the vertical member 103 into a curved surface, and since it does not need to use long bolts, it has an advantage that cost can be reduced. is there.

[0004]

[Problems to be solved by the device]

 However, according to the conventional connecting device having the above-described configuration, the horizontal support wall 102 in one of the mold members 101b forming the horizontal member 101 is brought into contact with the end face of the vertical member 103 before the horizontal support wall 102 is contacted. Since the screw 106 is inserted from the side opposite to the abutting side and screwed into the screw pocket 105, the tightening force by the screw 106 is directly concentrated on the horizontal support wall 102. , I am worried about the mechanical strength of this part. Further, since the screw-in position of the screw 106 is also determined by the position where the screw pocket 105 of the vertical member 103 is formed, even if a reinforcing member 107 or the like is separately provided in the upper mold member 101a, this is the screw-fastening position. You may be forced to change the specifications due to restrictions.
