Description

[Detailed Description of the Invention] The present invention relates to a handrail mounting device that is installed on a so-called weir wall, such as the roof of a building, the surrounding wall of a balcony, or a standing wall constituting a fence.

Traditionally, general-purpose handrails are installed with concrete roots wrapped inside the weir walls that make up the surrounding walls of rooftops and balconies, which creates a dead space on the outside of the handrail, which increases the amount of space on the rooftop. This has the disadvantage that the usable space on the balcony or balcony is narrowed, and the surface where the handrail is installed has a base mortar layer,
Because surface coating layers such as a waterproofing layer and finishing mortar layer are formed, the binding force of the wrapped concrete does not directly reach the building frame.
The erection strength was insufficient.

This invention was made to eliminate the above-mentioned drawbacks of the conventional methods.By installing handrails upright on the weir walls, it eliminates the conventional dead space on rooftops and balconies, and maintains sufficient erection strength. It is an object of the present invention to provide a handrail mounting device that can facilitate installation and reduce costs.

Hereinafter, the present invention will be explained based on illustrated embodiments.

In Fig. 1, reference numeral 1 is on a weir wall such as a rooftop or balcony, and rectangular cylindrical supports 3, 3... are erected at predetermined intervals on a weir wall cap 2 attached to the top of the weir wall. , 3... are connected in a T-shape to a horizontal handrail cap 4, and the supports 3, 3...
Horizontal beams 5, 5, .

FIG. 2 shows an anchor fitting 7 used for attaching the handrail. This anchor fitting 7 is manufactured from an extruded material of aluminum or its alloy, and is constructed in a saddle shape from a top plate part 7a and indoor and outdoor side plate parts 7b and 7c which are inclined so that their lower ends slightly protrude outward. has been done. However, the indoor side board part 7
The top part of b forms a convex Kasagi receiving part 8a with respect to the top plate part 7a, and the top part of the outdoor side plate part 7c is an L-shaped piece 7d that projects upward from the top plate part 7a, and is connected to the indoor side by an L-shaped piece 7d that projects upward from the top plate part 7a. Also, the lower ends of both side plate portions 7b and 7c form a Kasagi mounting portion 9 having screw holes 10 and 10, respectively. On the other hand, the top plate part 7a has a support rib 11 in the center that is shaped like an upright strip and whose upper end coincides with the line connecting the two capsular receivers 8a and 8b.
Screw-fastening recesses 12, 12 are formed on both sides of the holder, and mounting portions 13, 13, which are substantially U-shaped and open downward, are provided on both sides of the lower surface.
Attachment holes 14, 14 are opened at position 13.

On the other hand, 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, with the outer hanging wall portion 2c extending from the inner hanging wall portion 2b. Raise the top plate part 2a
By sloping the roof gently so that the indoor side is lower, drainage is improved. However, the degree of inclination of the top plate part 2a of the lever is
It matches that of the straight line connecting between a and 8b. Thus, substantially L-shaped ribs 2d, 2d bent downward are protruded from inside the lower end portions of both hanging wall portions 2b, 2c, and between each rib 2d, 2d and each lower end of the hanging wall portions 2b, 2c. A groove 15 that is open downward is formed. The support column 3 is similarly made of an extruded material made of aluminum or its alloy, and has a plurality of bis pockets 3a, 3a, . There is.

To provide a handrail, as shown in FIG. 3, an anchor fitting 7 is fitted over the top of the weir wall 1, with a spacer 16 made of a plastic liner or the like for height adjustment interposed as necessary. Both mounting parts 13,
At step 13, a foundation rod 17 such as a fisher plug is driven into the weir wall 1 through the attachment hole 14 and fixed. On the other hand, the weir wall cap 2 is fixed and integrated at the base of the pillar 3 with the screws 18 screwed into each bis pocket 3a, and this integrated weir wall cap 2 is placed on the anchor fitting 7, and the both side plates of the anchor fitting 7 are attached. The cap mounting parts 9 at the lower ends of 7b and 7c are press-fitted to the base of the rib 2d of the weir wall cap 2 using the elasticity of the material, and the lower surface of the top plate part 2a is brought into contact with the cap support parts 8a and 8b of the anchor fitting 7. By contacting them, a handrail is erected on the weir wall 1 as shown in FIG. 5, and a weir wall cap 2 is attached. At this time, the heads of the screws 18 are located in the screw fixing recesses 12 of the anchor fittings 8, and the supporting ribs 11 are located directly under the pillars 3 and abut against the lower surface of the weir wall cap 2. ing. Therefore, both side plate portions 7b and 7c of the anchor fitting 7 and both hanging wall portions 2b of the weir wall cap 2,
2c is fixed with screws 19 screwed into each screw hole 10 of the Kasagi attachment parts 9, 9. On the other hand, weir wall Kasagi 2
A watertight material holder 20 having a substantially L-shaped cross section is fixed to the lower ends of both hanging wall portions 2b and 2c by screwing screws 21 into the groove 15, and a frame portion 20a having a substantially U-shaped cross section at the tip of the holder 20. A watertight material 22 made of rubber or the like is fitted to provide a watertight seal between both hanging wall portions 2b, 2c and both side surfaces of the weir wall 1. In addition, the handrail cap 4 and the support post 3 are connected by connecting the upper end of the support post 3 and the bottom plate 4a of the handrail cap 4 to the bis pocket 3 of the support post 3 in the same way as the lower part.
Screw screws 18, 18... into a, 3a and secure them,
Further, an upper plate 4b having a substantially inverted U-shaped cross section is fitted onto the bottom plate 4a.

In the above embodiment, both hanging wall portions 2b and 2c of the weir wall cap 2 and both side plate portions 7b of the anchor fitting 7,
7c are fixed with screws, but each cap mounting portion 9 of the anchor fitting 7 may simply be engaged with the base of the rib 2d of the weir wall cap 2. Further, the support column 3 may have a shape other than a rectangular cylinder, such as a cylinder. Furthermore, the anchor fitting 7 can also be formed from a metal profile other than aluminum or its alloy.

As described above, since the handrail mounting device according to the present invention erects the handrail directly on the weir wall, there is no dead space around the outer periphery of the handrail unlike in the past, and it can be used on rooftops and balconies. This makes it possible to maximize the usable space, and since the installation of the weir wall cap and the erection of the handrails are done at the same time, the number of work steps is greatly reduced compared to the conventional method. Moreover, the anchor metal fittings that are fixed to the top of the weir wall are
It is formed into a saddle shape with a Kasagi receiving part and a Kasagi mounting part on both the indoor and outdoor sides, and a recessed part for screwing between the two Kasagi receiving parts on the top surface, and the cylindrical support of the handrail and a substantially downward U-shaped cross section. The weir wall cap of the shape is fixedly integrated with the weir wall cap through screws that are screwed into the plurality of longitudinal bis pockets provided on the inner surface of the pillar, and both hanging wall parts of this integrated weir wall cap are attached to both cap of the anchor fittings. Since the handrail is erected by being fixed to the handrail, the handrail can be installed very easily and reliably, and the erecting strength is also sufficient. Furthermore, since the anchor fittings are made of metal profiles, it is possible to use a large number of anchor fittings that are uniform with no difference in size, which results in extremely high handrail installation accuracy. At the same time, the parts manufacturing cost is greatly reduced compared to the case where each anchor fitting is manufactured separately.
