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.

In Fig. 1, reference numeral 1 denotes a weir wall such as a rooftop or balcony, and rectangular cylindrical supports 3, 3, . The upper ends of 3... are connected in a T-shape to the horizontally extending handrail cap 4, and the horizontal bars 5, 5... bridge between the supports 3, 3 at the lower positions, as well as the handrail cap 4 and the horizontal bars 5. Vertical beams 6, 6, whose upper and lower ends are supported and fixed are disposed on the sides. 7 is 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. This connecting fitting 8 is made by bending a single plate made of iron or stainless steel into a flat plate shape, and has an upwardly convex capacitor receiving part 8a in the center, and connecting pieces 8b, 8b on both sides thereof. Further, a square cylindrical support rod 9 made of iron, stainless steel, etc. is vertically welded to the center of the upper surface of the Kasagi receiving portion 8a. However, Kasagi receiving part 8a
are gently sloped so that the indoor side is lower, and vertically long fixing bolt insertion holes 10 are bored at horizontally opposing positions on both indoor and outdoor sides of the support rod 9. The length of the support rod 10 is set to be at least 1/2 of the total length of the support 3, and usually about 2/3.

FIG. 3 shows an anchor fitting 11 used when the weir wall 1 is made of lightweight foamed concrete (ALC). This anchor fitting 11 is formed by bending a single plate made of iron, stainless steel, etc. into a substantially downward U-shape, and includes a top plate portion 11a and an indoor outer wall portion 1.
1b, 11b, each side wall portion 11b is provided with an engaging piece 12 cut and raised from the lower end side in the center and extending diagonally outward, and vertically long bolt insertion holes 13, 1

On the other hand, as shown in FIG. 4, 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 is consistent with that of A rectangular hole 14, which is one size larger than the cross section of the support 3, is formed in the top plate 2a at a position corresponding to the support 3, and both hanging walls 2b, 2
Approximately L-shaped ribs 2d, 2d bent downward are protruded from the inside of the lower end of c, and a downwardly open groove 15 is formed between each rib 2d, 2d and each lower end of the hanging wall portions 2b, 2c. has been done.

To install the handrail, install the weir wall 1 as shown in Figure 4.
An anchor fitting 11 is fitted across the top of the weir wall 1, and a spacer 16 is inserted between the indoor side wall portion 11b and the indoor side surface of the weir wall 1 according to the degree of the gap between the two side wall portions 11b, 11b. The anchor bolt 17a is inserted through the weir wall 1, and the nut 17 is inserted from both sides.
Tighten and fix b and 17b. At this time, the height error in the mounting position of the anchor bolt 17a is absorbed within the length range of the anchor bolt insertion hole 13. Next, the connecting fitting 8 is positioned and placed on the anchor fitting 11, and the connecting piece 8 is placed on the anchor fitting 11 as shown in FIG.
Welding is performed at b and 8b to secure both metal fittings 8 and 11. Next, the handrail support post 3 is erected on the cap holder 8a of the connection fitting 8 so that the post fitting insertion rod 9 is inserted into it from the lower side, while the weir wall cap 2 is placed on the connection metal fitting 8. , and place the tip of the engagement piece 12 of the anchor fitting 11 on the ribs 2d, 2d of the weir wall cap 2.
The top plate part 2a is press-fitted to the base of the
is fitted onto the weir wall 1 by superimposing it on the capacitor receiving part 8a of the connecting fitting 8. As shown in FIG.
The fixing bolt 18a is passed from the indoor side to the outdoor side through the fixing bolt insertion holes 10, 10 and the circular holes 3a, 3a made in the support column 3, and the nut 1 is inserted through the fixing bolt 18a from the indoor side to the outdoor side.
8b and tighten to secure. At this time, the vertical relative error between the column 3 and the column insertion rod 9 is absorbed within the length range of the fixing bolt insertion hole 10.

In addition, contrary to the above, it is also possible to adopt a construction order in which the support 3 and the support insertion rod 9, that is, the connection fitting 8 are connected first, and the connection fitting 8 and the anchor fitting 11 are connected later. It is possible, and the weir wall cap 2 may be crowned either before or after the pillars 3 are erected.

Next, caulking material 20 is filled in the annular groove 19 formed between the outer circumference of the lower end of the support column 3, the inner circumference of the rectangular hole 14 of the weir wall cap 2, and the cap support part 8a of the connection fitting 8, and then A cosmetic cap 7 is attached to seal the base of the support column 3 watertightly. On the other hand, a watertight material holder 21 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 22 into the groove 15, and the tip of the holder 21 has a cross section approximately Character-shaped frame portion 21
A watertight material 23 made of rubber or the like is fitted to a to provide 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, and 24 is a finishing mortar layer provided on the indoor side of the weir wall 1. Also, to connect the handrail cap 4 and the post 3, connect the upper end of the post 3 and the bottom plate 4a of the handrail cap 4 by screwing screws 25, 25, etc. into the bis pockets 3b, 3b... of the post 3 shown in FIG. The upper plate 4b, which has a substantially U-shaped cross section, is then fitted onto the bottom plate 4a.

The above description is based on the case where the weir wall 1 is made of ALC, but if the weir wall 1 is made of reinforced concrete (RC), for example, as shown in FIG. 26, and the other parts are the same as those shown in the fourth figure, and the foundation stud 27 such as a hole-in anchor or dry pit is attached to the anchor metal fitting 2 on the weir wall 1.
By driving through the anchor fitting 2
6 to the top of the weir wall 1, and then the ALC described above.
As in the case of the weir wall, the support 3 and the support insertion rod 9 are fitted and fixed, and the connection fitting 9 and the anchor fitting 2 are fixed.

0, fitting the cosmetic cap 7, and fixing the watertight material holder 21 with screws.

In addition, in the above, one each for ALC and RC.
Although various types of anchor fittings 11 and 26 and one type of connection fitting 8 are illustrated, the structure of these and the fixing method of 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 be applied to cases where the support is made of other materials such as wood, block, etc. Furthermore, the support rod 9 and the support support 3 may have other shapes such as a cylindrical shape instead of a rectangular cylinder shape.

On the other hand, in the above-mentioned embodiment, the column 3 and the column insertion rod 9 are fixed using the fixing bolt 18a and the nut 18b. It is also possible to fix the strut insertion rod 9 to the strut 3. FIG. 8 and FIG. 9 show an example of this, and the horizontal bar 5 is made of an extruded material of aluminum or its alloy, and has a substantially downward U-shaped cross section.
Ribs 5a, 5b are formed on the upper and lower sides of both inner surfaces of the upper ribs 5a, 5a, cut and raised portions 5c are provided on the upper ribs 5a, 5a, and the L-shaped mounting piece 28 is fitted between the upper and lower ribs 5a, 5b, and screws 29, 29 are formed. After securing it with a bolt, attach the connecting bolt 30a by penetrating the post fitting insertion rod 9, the post 3 and the mounting piece 28, and then tighten the nut 30b,
30c is screwed and fitted to attract and fix the above three parts. In such a connection structure, the column insertion rod 9
The bolt heads and nuts required for fixing the handrail are not exposed to the outside, and the appearance of the handrail is clean and good-looking.

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. It is 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, since the anchor fitting fixed to the top of the weir wall and the connecting fitting are connected and fixed by welding, the connection strength is extremely high, and the horizontal position of the connecting fitting can be arbitrarily adjusted in all directions. Furthermore, the structure is such that a post-fitting rod is planted on the cap holder part of the connection fitting, and the post-fitting rod is fitted into the cylindrical column of the handrail and fixed with horizontal bolts. The pillars are held extremely firmly, making the standing state stable, and the handrail has great strength against external forces that try to topple it indoors or outdoors, resulting in excellent safety. Therefore, the connection fittings, the anchor fittings, and the connection structure between the support and the support rod have the advantage that they are simple in structure and can be manufactured at low cost.
