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 work.

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

The upper ends of these supports 3, 3... are connected in a T-shape to a horizontally extending handrail cap 4, and the horizontal beams 5, 5... bridge between the supports 3, 3 at a lower position. Further, vertical bars 6, 6, . . . whose upper and lower ends are supported and fixed to the handrail cap 4 and the horizontal bar 5 are arranged. Reference numeral 7 designates a rectangular dish-shaped decorative cap fitted at the base of each support 3.

FIG. 2 shows a connecting fitting 8 used for attaching the handrail. Each part of the connection fitting 8 is made of stainless steel or the like, and a square cylindrical support is inserted into the center of a board 8a, which has circular coupling bolt insertion holes 9 on each side of the indoor and outdoor sides. A rod 10 is installed vertically by welding, and a flange-shaped cap support plate 11 is welded and fixed to the lower part of the column-fitting rod 10 over the entire circumference. Thus, the Kasagi receiving plate 11 is gently sloped so that the indoor side is lower, and vertically long bolt insertion holes 12, 12 are bored at opposing positions on both sides of the post-fitting rod 9. In addition, the post fitting insertion rod 10 has a Kasagi receiving plate 11.

The anchor fitting 13 is fixed thereon by welding 21 or by screwing a screw 23 as shown in FIG. 6 between the horizontal pieces 17b and 18b. Next, a spacer 24 is inserted as necessary on the anchor fitting 13, and the connecting fitting 8 is placed so that each connecting bolt 14a passes through the insertion hole 9, and a large diameter washer is inserted into each connecting bolt 14a. 14
Screw the nut 14b through c to connect both metal fittings 8,1.
Connect and fix 3. At this time, the height of the connecting fitting 8 can be adjusted by the thickness of the spacer 24, and by setting the insertion hole 19 to have a larger diameter than the connecting bolt 14a, the connecting fitting 8 can be adjusted within the range of the diameter difference.
The horizontal position can also be adjusted. Next, insert the post fitting rod 10 into the handrail post 3 from below.
The capacitor plate 11 of the connection fitting 8 is inserted so that the
On the other hand, as shown in FIG. 7, the weir wall cap 2 is superimposed on the cap support plate 11 and attached to the weir wall 1. Also, the pillar 3 and the pillar insertion rod 10 fitted into it
As shown in FIGS. 9 and 10, the space between the upper and lower ribs 5a and 5b provided on both sides of the inner surface of the horizontal bar 5, which is formed from an extruded material of aluminum or its alloy and has a substantially downward U-shaped cross section. , L-shaped mounting piece 2
5 is fitted using the cut and raised part 26 formed on the upper rib 5a, and after being prevented from coming off with screws 27, 27, the post fitting inserting rod 10, the post 3 and the mounting piece 25 are penetrated. Then, remove the connecting bolt 28a, and screw and tighten the nut 28b to connect.

In addition to using the connecting portion between the horizontal beam 5 and the column 3 as described above, the column 3 and the column insertion rod 10 may be fixed using a fixing bolt 29a and a cap nut 29b, as shown in FIG. You can. However, according to the fixing method shown in FIGS. 9 and 10, the connecting tool is not exposed to the outside, so there is an advantage that the appearance is excellent. In addition, the support 3 and the support insertion rod 10, that is, the connection fitting 8
A construction order may be adopted in which the connecting fittings 8 and the anchor fittings 13 are connected first, and then the connecting fittings 8 and the anchor fittings 13 are connected later.

Next, as shown in Figure 7, the outer periphery of the pillar 3 and the weir wall cap 2
The annular groove 30 formed between the inner periphery of the rectangular hole 15 and the Kasagi receiving plate 11 of the connection fitting 8 is filled with caulking material 31, the decorative cap 7 is attached on top of this, and the base of the support post 3 is soaked with water. Seal. On the other hand, each lower end of both hanging wall parts 2b and 2c of the weir wall cap 2 has a cross section of approximately L.
A watertight material holder 32 made of rubber or the like is fixed by screwing a screw 33 into the groove 16, and is fitted into a frame 32a having a substantially U-shaped cross section at the tip of the holder 32.

Reference numeral 35 denotes a finishing mortar layer provided on both indoor and outdoor sides of the weir wall 1, which covers the indoor side so that the reinforcing plate 20 is not exposed to the outside. Furthermore, 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 pockets 3a, 3a of the support post 3 shown in FIG.
This is done by screwing the screws 36, 36... into and fixing them, and then fitting the top plate 4b, which has a substantially U-shaped cross section, to the bottom plate 4a.

In the above embodiment, the cap support plate 11 is fixed to the support rod 10 of the connection fitting 8, but the method of attaching the weir wall cap 2 to the weir wall 1 can be modified in various ways. Further, the reinforcing plate 20 may be omitted depending on the case, and other auxiliary reinforcing means may be used instead. In addition, the strut 3 and the strut insertion rod 11
may have a shape other than a square cylinder, such as a cylinder.

As described above, the handrail mounting device according to the present invention erects the handrail directly on the weir wall, so there is no dead space around the outer periphery of the handrail as in the past, and it can be used on rooftops or other places. It is possible to maximize the usable space of the veranda, and since the installation of the weir wall cap and the erection of the handrail are done at the same time, the number of work steps is greatly reduced compared to the conventional method. Moreover, in the present invention, the indoor and outdoor corners of the top of the weir wall are each covered with angle members, and the vertical pieces of both angle members are attached to each other using a through bolt penetrating the weir wall and a nut screwed into the bolt. Because the anchor metal fittings are fixed between the horizontal pieces of both angle members, the weir wall in particular is made of a material that is weaker than ordinary reinforced concrete (RC) such as lightweight foamed concrete (ALC). Even if
Provides sufficient strength to withstand the erection of handrails. Further, a connecting bolt protruding upward is planted in the anchor fitting, an insertion hole for the bolt is formed in the connecting fitting interposed between the weir wall cap and the anchor fitting, and both fittings are attached to the connecting bolt. Since it is fastened and fixed with a screwed nut, the height of the connecting fitting can be adjusted arbitrarily by inserting a spacer etc. between the two fittings, and therefore the height can be adjusted to the top surface of the weir wall itself. Even if there is a difference, it is possible to install the handrail reliably without any problem. In addition, the structure is such that a post-fitting rod is installed on the cap holder part of the connection fitting, and the post-fitting rod is fitted and fixed inside the cylindrical column of the handrail, so that the column is firmly held and can be easily erected. The installed state is stable, the handrail has great strength against external forces that try to topple it indoors and outdoors, and combined with the reinforcing effect of the angle material mentioned above, it is excellent in safety. Therefore, the connection fittings and anchor fittings have a simple structure and can be manufactured at low cost.
Furthermore, since the two can be easily connected, there is an advantage that the installation work of the entire handrail is simplified.
