For this reason, in the aspect in which the horizontal piece (22b) forms an angle of about 30 ° corresponding to the above angle with respect to the vertical piece (22a) of the support body (22), the horizontal piece is largely twisted and extends horizontally. Has been done. That is, as shown in FIG. 2, the horizontal piece (22b) projects in a direction forming an angle (θ2) of about 30 ° in a plan view with respect to the plane where the mounting side surface (1b) of the main pillar (1) exists. It has been done. Thereby, the horizontal piece (22b) is
It is arranged to be arranged substantially parallel to the nose (3a) direction of the corresponding tread (3) and on the lower surface side of the close position. In addition, the reinforcing body (32) also corresponds to the twisted shape of the support body (22) in a state where the contact piece portions (32b) (32b) at both ends thereof are twisted with respect to the inclined piece portion (32a). It is supposed to be extended.

This rotation moment is generated by the vertical plate (2
It acts as a large shearing force on the mounting screw (9) that fixes 2a) to the main pillar (1). Therefore, unless some measures are taken, the load repeatedly applied to the tread (3) makes the mounting of the support (22) to the main pillar (1) uncertain, which causes rattling and squeaking. There is a risk.

By forming the, the rotation moment of the receiving metal fitting (12) generated by the load received from the tread (3) side is generated on the side surface (1a) side of the main pillar (1) via the locking edges (22c) (32c). The receiving and preventing the vertical piece (22a) from being subjected to a large force other than the vertical load, and thus the mounting screw (9) from being subjected to a large shearing force,
The mounting strength of the tread (3) can be kept stable.

As shown in FIG. 6, the horizontal piece (23b) is at an angle (θ3) of about 60 ° with respect to the mounting side surface (1b) of the main post (1) to which the vertical piece (23a) of the support body (23) is screwed and fixed. ) Has been made to be twisted to make. Further, even in the third receiving fitting (13), the contact piece portion (33b) of the reinforcing body (33) is twisted with respect to the inclined piece portion (33a) in accordance with the above twist angle (θ3). Needless to say, it is formed in the.

Since a large amount of vertical load acts on one side, the above-mentioned rotational moment acting on the receiving metal fitting is not so large. Therefore, as in the case of the second receiving fitting (12), the locking protrusions (22c) (32
There is no particular need to form c). However, since it is undeniable that a rotational moment acts even if it is small,

Since the reinforcing members can be combined and attached after that, the screwing and fixing work can be easily performed without any interference or interference with the other member. Furthermore, since the support has a plurality of screw holes formed in the vertical and horizontal pieces, each of which includes a mounting screw hole formed by an elongated hole, the metal fitting using the elongated hole is used. The fine adjustment of the mounting height position and the fine adjustment of the horizontal mounting position of the tread can be easily performed, which can improve the construction workability on site at times and also facilitate the mounting position accuracy.

The second invention according to claim 2, which has an edge.
Similarly, in the mounting bracket for the tread according to the present invention, even though the horizontal piece of the inverted L-shaped support is twisted at a relatively large angle with respect to the vertical piece, the vertical piece At least one of one side edge on the nose side of the portion and one end edge on the nose side of the lower contact portion of the reinforcing body is formed with a locking projecting edge to be engaged with the adjacent mounting side surface of the main pillar. Since it is designed to receive the rotation moment of the receiving metal fitting generated by the load applied from the staircase tread, it is ensured that a large rotation moment acts on the vertical piece by receiving it with the above-mentioned locking projection edge. Can be prevented. Therefore, it is possible to prevent a large shearing force from acting on the mounting screw that fixes the vertical piece to the main pillar, which in turn causes the mounting state of the receiving bracket to loosen, causing rattling or a squealing phenomenon. Therefore, it is possible to maintain a stable and strong attachment state of the tread over a long period of time.
