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.

Further, as shown in FIG. 5, the support column 3 is 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.

To install the handrail, install the weir wall 1 as shown in Figure 4.
The anchor fitting 12 is fitted across the top of the weir wall 1, and a spacer 18a is inserted between the indoor side wall 12b and the indoor side of the weir wall 1 according to the degree of the gap between the two side walls 12b, 12b. Anchor bolt 19a
is inserted through the weir wall 1, and the nut 1 is inserted from both sides.
Tighten and fix 9b and 19b. At this time, the height error in the mounting position of the anchor bolt 19a is absorbed within the length range of the anchor bolt insertion hole 15.
On the other hand, contact the Kasagi receiving part 8a of the connection fitting 8 with the base of the support column 3, screw the screws 20 into the screw pockets 3a through the respective screw insertion holes 10, and
The lower end of the through bolt 21a inserted into the support column 3 is made to protrude downward from the through bolt insertion hole 9, and the nut 2
By screwing 1b, the support 3 and the connection fitting 8 are fixed together. Then, insert the spacer 18b on the anchor fitting 12 as necessary,
Connecting the connecting fittings 8 of the above-mentioned one piece with each connecting bolt 13
A is placed on the anchor fitting 12 so that it passes through the coupling bolt insertion hole 11, and as shown in FIG. Fix it and erect the support post 3. At this time, the height of the connection fitting 8 is equal to the height of the spacer 1.
Adjustment can be made by adjusting the thickness of the connecting bolt 8b, and the position can also be adjusted in the indoor and outdoor directions within the range of the coupling bolt insertion hole 11. Next, the weir wall cap 2 is placed on the connection fitting 8, and the anchor fitting 1 is placed on the base of the ribs 2d, 2d.
The tips of the engaging pieces 14 of 2 are press-fitted using the elasticity of the material, and the top plate portion 2a is connected to the capacitor receiving portion 8a of the connecting fitting 8.
By polymerizing on top, it is attached to the weir wall 1. Next, the outer circumference of the lower end of the pillar 3 and the square hole 16 of the weir wall cap 2
An annular groove 22 formed between the inner periphery and a cap holder 8a of a connecting fitting 8 is filled with a caulking material 23, and a decorative cap 7 is attached thereon to watertightly seal the base of the support 3. Further, a watertight material holder 24 having a substantially L-shaped cross section is fixed to the lower ends of both hanging wall portions 2b and 2c of the weir wall cap 2 by screwing screws 25 into the groove 17.
A watertight material 26 made of rubber or the like fitted to a frame portion 24a having a generally U-shaped cross section at the tip of the holder 24 provides a watertight seal between both hanging wall portions 2b, 2c and both side surfaces of the weir wall 1. 1a is a waterproof sheet pasted from the top surface of the weir wall 1 to the indoor side surface, and 27 is a mortar layer provided on the indoor side of the weir wall 1. On the other hand, 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 each bis pocket 3a in the same way as the lower end.
At the same time, the upper end of the through bolt 21a penetrates the bottom plate 4a and protrudes upward through the screw 20, and the nut 21b is screwed and tightened. This is done by engaging the plate 4b.

The case where the weir wall 1 is made of ALC has been described above, but if the weir wall 1 is made of reinforced concrete (RC), for example, as shown in FIG. 1
Using a flat anchor fitting 28 made of iron, stainless steel, etc., with a hole-in anchor or dry pit installed on the weir wall 1, the other parts are the same as those shown in the fourth figure. Shipped rod 29
By driving through the anchor fitting 28, the anchor fitting 28 is fixed to the top of the weir wall 1, and from then on, the support 3 and the connecting fitting 8 are connected and connected in the same manner as in the case of the ALC weir wall described above. Connection of the fitting 8 and the anchor fitting 28, crowning of the weir wall cap 2,
What is necessary is to fill the caulking material 23, fit the decorative cap 7, and fasten the watertight material holder 24 with screws.

In addition, in the above, one each for ALC and RC.
Although various types of anchor fittings 12 and 28 and one type of connection fitting 8 are illustrated, the structure of these and the method of fixing the anchor fittings to the weir wall 1 can be modified in various ways other than those shown in the examples, and the weir wall 1 may be made of steel. The present invention can also be applied to cases where the support pillar 3 is made of other materials such as wood, block, etc. Furthermore, the support support 3 may have a shape other than a square cylinder, such as a cylindrical shape. In addition, in the above embodiment, the through bolt 21a and nut 21b inserted into the pillar 3 are used as auxiliary tools for connecting the pillar 3 and the connecting fitting 8, but the connection strength by the bis pocket 3a and the screw 20 is very high. Therefore,
Such auxiliary tools can also be omitted.
Therefore, it is desirable that the number of bis pockets 3a be three or more and equally distributed in the circumferential direction.

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. In addition, a connecting bolt that protrudes upward is installed in the anchor fitting fixed to the top of the weir wall, and an insertion hole for the bolt and a cap receiving part are formed in the connecting fitting interposed between the weir wall cap and the anchor fitting. However, since both metal fittings are tightened and fixed with a nut that is screwed onto the above-mentioned connecting bolt, the height of the connecting metal fittings can be adjusted as desired by inserting a spacer etc. between the two metal fittings. Therefore, even if there is a height difference on the top surface of the weir wall itself, it is possible to reliably attach the handrail without any problem. Furthermore, the connection between the cylindrical column and the connecting fitting is achieved through a plurality of bis pockets formed along the longitudinal direction on the inner surface of the column and screws that are screwed into these, which increases the connection strength and improves the handrail. The installation strength is sufficient and safety is excellent. Therefore, the connecting fittings and the anchor fittings have a simple structure and can be manufactured at low cost, and since they can be easily connected, there is an advantage that the installation work of the entire handrail is simplified.
