①
Carry out centering and then make
prepared holes for anchor bolts, which are
φ
6 mm and 105 mm or more in depth from
the finished wall surface.
②
Make through holes of
φ
14 mm for metal
pipes only in the gypsum board part.
③
Insert the metal pipes until they hit the
concrete base surface, and cut it in such a
way that it protrudes about 0.5 mm from the
finished wall surface.
*If the length is not enough, insert a washer
to adjust the length.
④
Screw the nuts about 2 mm from the upper
ends of the anchor bolts, put the bolts
through the metal pipes, and then drive
them in the prepared holes lightly.
⑤
Tighten the nuts on the anchor bolt. (This
opens the wedges of the anchor bolts and
prevents the anchor bolts from coming out.)
⑥
Remove the nuts from the anchor bolts.
⑦
Adjust the projecting length of the anchor
bolts to be between 9 and 16 mm from the
finished wall surface.
⑧
Put the anchor bolts through the mounting
holes of the flange, and then tighten with
the washers and nuts.
⑨
Press the cover against the finished surface.
①
While carrying out centering, fix the
mounting plate to the reinforcing
light-gauge steel frame (t 2.3 mm or more)
by welding.
②
Screw the continuous-thread studs into the
holes of the mounting plate, adjust their
projecting length to be between 9 and 16
mm from the finished wall surface, and
tighten from the back of the wall with nuts.
③
Finish the wall.
④
Put the continuous-thread studs through the
mounting holes of the flange, and then
tighten with the washers and nuts.
⑤
Press the cover against the finished surface.
*You cannot adjust the
mounting position of
the handrail after
finishing the wall.

Note 1: Use a drill that can make prepared holes of
φ
6 mm and 105 mm or
more in depth in concrete. If the bit size of the drill is too large or if it
has core deviation, you may fail to fix it securely.
Note 2: The embedding length of the anchor bolts in concrete must be 37 mm
or more.
Note 3: Adjust the projecting length of the anchor bolts to be between 9 and 16
mm from the finished wall surface.
Note 1: Use reinforcing light-gauge steel frames of t 2.3 mm or more.
Note 2: Adjust the projecting length of the continuous-thread studs to be
between 9 and 16 mm from the finished wall surface.
Note 3: Be careful not to overtighten the nuts to avoid tiles from breaking.
