Another object of the present invention is to provide a low-cost mounting device that can be easily and reliably mounted to weir walls having different widths in the indoor direction, and can provide sufficient erection strength.

(Means for Solving the Problem) In order to achieve the above object, the handrail mounting device according to this invention provides a plurality of bis pockets along the longitudinal direction on the inner surface of the cylindrical support of the handrail, and A plurality of screw insertion holes corresponding to the above-mentioned screw pockets are provided on the upper wall of the shaped anchor hardware, and the mounting bracket, which forms a pair for indoor and outdoor use, is approximately inverted L-shaped and consists of an overhanging piece and a hanging piece. A long hole in the indoor/outdoor direction is drilled in one part, and both mounting brackets are screwed through the long hole to the lower end surface of the hanging wall of the anchor hardware, and a weir wall cap with a substantially downward U-shaped cross section is attached to the base of the support. and the above-mentioned anchor metal fittings superimposed on the lower surface thereof are fixedly integrated with screws that are screwed from below into the above-mentioned bis pockets through the screw insertion holes, and this integrated anchor metal fitting is fitted over the top of the weir wall, and can be used indoors or outdoors. Place the hanging pieces of both mounting brackets against both sides of the weir wall, and screw and tighten the nuts on the through bolts that penetrate the hanging pieces of both mounting brackets and are inserted into the weir wall indoors and outdoors to erect the handrail. It was designed to be set up.

(Example) This invention will be explained below based on the illustrated example.

In Fig. 1, reference numeral 1 is a weir wall made of lightweight foamed concrete (ALC) on a rooftop or balcony, etc., and rectangular cylindrical supports 3, 3... are placed at predetermined intervals on a weir wall cap 2 attached to the top of the weir wall. The upper ends of these columns 3, 3... are connected in a T-shape to a horizontal handrail cap 4, and horizontal beams 5, 5... , as well as vertical bars 6, 6, whose upper and lower ends are supported and fixed to the handrail cap 4 and the horizontal bar 5.

FIG. 2 shows an anchor metal fitting 7 and a pair of indoor and outdoor fittings 8, 8 used for attaching the handrail. This anchor hardware 7 is a thick-walled molded product made of die-cast aluminum or its alloy, and has an upper wall portion 7a whose upper surface is low and gently sloped toward the indoor side.
It is constructed in a saddle shape with both indoor and outdoor hanging wall portions 7b and 7c whose outer surfaces are sloped surfaces that protrude outward toward the bottom. Thus, a groove-shaped screw fixing recess 9a is formed in the center of the lower surface of the upper wall portion 7a and continues in a direction parallel to both walls 7b and 7c. Screw insertion holes 10 are formed so as to be equally spaced in the circumferential direction. Furthermore, groove-shaped recesses 9b parallel to the recess 9a are formed on the inner surfaces of both the hanging wall portions 7b and 7c, and the lower surface of each recess 9b and the hanging wall portions 7b and 7c have a high and gentle slope on the outside. A screw hole 11 (see FIG. 3) is provided between the lower end surface and the screw hole 11 (see FIG. 3).

On the other hand, each mounting bracket 8 is made of light alloy such as iron, stainless steel, or aluminum, and has an inclined projecting piece corresponding to the lower end surface of both hanging walls 7b and 7c of the anchor hardware 7. 8a and hanging piece 8
It is formed into a substantially L-shape from b. Thus, elongated holes 12a in the indoor and outdoor directions are bored in the overhanging piece 8a at positions corresponding to the screw holes 11 of the anchor hardware 7, and elongated holes 12b in the vertical direction are bored in the hanging piece 8b. , 12b are bored.

As shown in FIG. 3, the weir wall cap 2 is made of a long plate material made of extruded aluminum or its alloy and has a substantially downward U-shaped cross section.
c is made higher than the inner hanging wall part 2b, and the top plate part 2a is gently sloped so that the indoor side is lower, thereby imparting drainage properties. However, the degree of inclination of the top plate portion 2a of the lever is set to match that of the upper surface of the upper wall portion 7a of the anchor hardware 7. Also, both wall hanging parts 2
Roughly L-shaped ribs 2d, 2d bent downward are protruded from inside the lower ends of b, 2c, and each rib 2d, 2d
A downwardly open groove 2e is formed between the lower end of the hanging wall portions 2b and 2c. Further, the support column 3 is similarly formed from an extruded material of aluminum or its alloy, and has a plurality of bis pockets 3a, 3a, . . . provided on its inner surface along the longitudinal direction, as shown in FIG. Each of these screw pockets 3a is set to correspond to each screw insertion hole 10 of the anchor hardware 7.

To erect the handrail, as shown in Figure 3,
Bolt insertion holes 13 facing indoors are bored at important points in the weir wall 1. Therefore, both hanging wall portions 7 of the anchor hardware 7
The overhanging piece 8a of the mounting bracket 8 is attached to the lower end surface of each of c and 7c.
are placed facing each other, and the screw 14 is loosened and screwed into the screw hole 11 from below through the elongated hole 12a. As a result, the mounting fittings 8, 8 are suspended from the anchor fitting 7 so as to be movable indoors and outdoors within the range of the elongated holes 12a, 12a. Next, the weir wall cap 2 is brought into contact with the base of the pillar 3 via the packing material 15, and the anchor hardware 7 is superimposed on the inside thereof, and the screw 16 is inserted into the insertion hole 1 from below.
By screwing into the bis pocket 3a of the support 3 through 0, the support 3, the weir wall cap 2 and the mounting bracket 8,
8 is fixedly integrated with an anchor metal fitting 7 that suspends it. As shown in FIG. 4, this one-piece anchor hardware 7 is fitted across the top of the weir wall 1, and the hanging pieces 8b of both mounting brackets 8, 8 are attached to both indoor and outdoor sides of the weir wall 1, respectively. While abutting and tightening the screw 14, both hanging pieces 8b, 8b's elongated holes 12b, 12b
The through bolt 17a passes through the bolt insertion hole 13 of the weir wall 1, and nuts 17b, 17 are attached to both ends of the through bolt 17a.
Screw and tighten b. After the above-mentioned integral part is installed, a watertight material holder 18 made of extruded aluminum or its alloy is inserted into the groove 2e with screws 19 at the lower ends of both hanging wall portions 2b and 2c of the weir wall cap 2.
Both hanging walls 2b, 2c of the weir wall cap 2 are screwed in and fixed by a watertight material 20 made of rubber or the like fitted to the frame 18a having a substantially U-shaped cross section at the tip of the holder 18.
A watertight seal is made between the lower end of the weir wall 1 and both sides of the weir wall 1.
In addition, the connection between the handrail cap 4 and the support post 3 is as follows.
The upper end and the bottom plate 4a of the handrail cap 4 are fixed by screwing the screws 16 into each bis pocket 3a of the column 3 in the same way as the lower part, and the top plate 4b, which has a substantially inverted U-shaped cross section, is further attached to the bottom plate 4a. It is done by fitting.

In addition, 21a is a reinforcing angle material fixed from the top surface of the weir wall 1 to the indoor side, 21b is a reinforcing flat plate fixed to the top surface on the outdoor side, and 22 is attached to the indoor side of the weir wall 1. 23 is a finishing mortar layer provided on the indoor side of the tarpaulin sheet.

This idea can also be applied when the weir wall 1 is made of other materials other than lightweight foamed concrete (ALC) such as reinforced concrete or steel; however, lightweight foamed concrete has less strength than other materials. This invention is especially effective when used as a mounting device, since it is vulnerable to Furthermore, by forming the anchor hardware 7 from die-casting made of aluminum or its alloy, there is an advantage that a thick wall can be easily obtained, and the mounting fittings 8 can be easily attached.

(Effects unique to the invention) According to the mounting device according to this invention, the handrail can be installed directly on the weir wall, so it is possible to maximize the dead space on the outer periphery of the handrail as in the past. Since the installation of the weir wall cap and the erection of the handrail are done at the same time, the amount of work required is greatly reduced compared to the conventional method, and the mounting brackets on both sides are screwed to the anchor metal fittings through long holes. The same mounting device can be used for weir walls having different widths in the indoor and outdoor directions within the range of the elongated hole. Furthermore, the mounting device of this invention has a simple structure, low material cost, and easy installation, and has the advantage of being able to erect a handrail firmly even against a weir wall made of lightweight foamed concrete, which has weak strength. be.
