Next, as shown in FIGS. 9 and 10, a drill screw 250 is screwed into the upper chord member 20 and the lower chord member 30 from the inside of the raised portion 62 of the bracket 6 through the hole 621. The drill screw 250 is screwed into the inner surface portions 22 and 32, and further draws the upper chord material 20 and the lower chord material 30 inward to a position where the inner surface portions 22 and 32 come into contact with the raised portion 62.
At this time, the upper chord member 20 has the bolts 220 tightened, and since there is almost no clearance that allows the upper chord member 20 to move outward with respect to the bracket 6, the outer chord member 20 is almost outward even when the tip of the drill screw 250 abuts. When the tap of the drill screw 250 starts to work without moving, the upper chord material 20 is attracted to the upright portion 62 of the bracket 6 and fixed.
On the other hand, since the lower chord member 30 is not provided with the back plate 210 or the bolts 220, the lower chord member 30 is pushed outward when the tip of the drill screw 250 comes into contact, but stops at a position where the regulating piece 38 comes into contact with the locking piece 64. For this reason, the tap of the drill screw 250 starts to work, and the lower chord member 30 is attracted to the upright portion 62 and fixed similarly to the upper chord member 20. Therefore, a fixing screw for fixing the upper chord member 20 and the lower chord member 30 to the upright portion 62 is constituted by the drill screw 250.
Thus, the panel unit 2 is fixed to the column 3.

Next, as shown in FIG. 2, the handrail head 5 is installed on the column connection plate 125 at the upper end of the column 3 and fixed by the bolt 128 inserted through the hole 127 of the column connection plate 125. Further, a cover material is attached to the end of the handrail headboard 5.
The handrail wall 1 is installed on the parapet 110 by the above procedure.

[Effect of the embodiment]
According to this embodiment, there are the following effects.
The bracket 6 attached to the column 3 is provided with the upright portion 62, the mounting portion 63, and the locking piece 64, and the locking grooves 200, 300 are formed on the lower surfaces of the upper chord material 20 and the lower chord material 30 of the panel unit 2. The upper chord member 20 and the lower chord member 30 can be placed on the placing portion 63 in a state where the engaging piece 64 is inserted into the engaging grooves 200 and 300.
That is, since the weight of the panel unit 2 is supported by the mounting portion 63 of the bracket 6 and the locking piece 64 prevents the panel unit 2 from falling down, the panel unit 2 can be temporarily placed. After the panel unit 2 is temporarily placed, the operator does not need to support the panel unit 2 and can perform screwing work or the like. Therefore, even a single operator can attach and assemble the handrail wall 1 by attaching the panel unit 2 to the support column 3, so that the installation workability of the panel unit 2 can be improved.

  Since the width dimension of the locking grooves 200 and 300 is set to be larger than the thickness dimension of the locking pieces 64, the locking pieces 64 can be easily inserted into the locking grooves 200 and 300. . For this reason, the mounting workability of the panel unit 2 can be further improved, and the locking piece 64 can be easily prevented from hitting the upper chord member 20 and the lower chord member 30 and being damaged.

Since the locking grooves 200 and 300 are formed on the lower surface of the upper chord member 20 and the lower chord member 30, rainwater and dust are less likely to enter compared to the case where they are formed on the inner surface portions 22 and 32. Even if rainwater or the like enters the locking grooves 200 and 300 due to an influence or the like, the rainwater or the like can be easily discharged by gravity. Therefore, since the locking grooves 200 and 300 are well drained and do not generate a water pool, cleaning is unnecessary, and even when a futon is dried on the handrail wall 1, the water accumulated in the locking grooves 200 and 300 is Can prevent the futon from getting wet.
Further, since the locking grooves 200 and 300 are not exposed to the interior of the panel unit 2, the interior design of the handrail wall 1 can be improved.

Since the locking grooves 200 and 300 are continuous in the longitudinal direction of the upper chord material 20 and the lower chord material 30, the left and right sides of the panel unit 2 are temporarily placed with the locking pieces 64 disposed in the locking grooves 200 and 300. The position can be adjusted. Further, since the upper chord member 20 and the lower chord member 30 are fixed to the bracket 6 by the drill screw 250, the panel unit 2 can be attached at the adjusted left and right positions. Further, the position of the bracket 6 can be adjusted inward and outward with respect to the support column 3 through the elongated hole 611. For this reason, it is possible to easily adjust the position of the panel unit 2 in the left-right direction and the inside-outside direction.
Further, the back plate 210 is disposed in the locking groove 200 of the upper chord member 20, and the bolt 220 inserted into the locking groove 200 from the mounting portion 63 of the bracket 6 is lightly screwed into the back plate 210, whereby the back plate 210. The left and right positions of the panel unit 2 can be adjusted while guiding the locking groove 200. For this reason, the panel unit 2 can move in the left-right direction stably and can adjust the position without rattling in the direction of finding.

  When the back plate 210 is brought into contact with the locking piece 64 of the bracket 6, the hole 633 and the screw hole 211 are designed to be coaxially aligned. Positioning can be performed, and the screwing operation of the bolt 220 can be easily performed.

When the drill screw 250 is screwed into the upper chord material 20, the back plate 210 and the bolt 220 are fully tightened, and there is almost no clearance, so that the movement of the upper chord material 20 to the outside can be restricted. For this reason, the drill screw 250 can be screwed in with a tap.
Even when the drill screw 250 is screwed into the lower chord member 30, the lower chord member 30 can no longer move outward at the position where the restricting piece 38 abuts against the locking piece 64, and the drill screw 250 can be screwed by applying a tap.
For this reason, when performing the screwing operation of the drill screw 250, the operator does not need to press the upper chord material 20 and the lower chord material 30, and can be fixed only by screwing from the inside of the balcony. Therefore, it is not necessary to construct a scaffold outside the balcony, and the construction work can be performed easily and safely.

Since the back chord member 30 is not provided with a back plate or bolts, the gap with the headboard 4 can be minimized. For this reason, it can also prevent a thing falling from the clearance gap between the lower chord material 30 and the coping 4.
In addition, since the lower chord material 30 is not in close contact with the headboard 4, water does not remain between the lower chord material 30 and the headboard 4 due to surface tension, and the water drainage can be improved.
