Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a method and device for attaching a handrail to be installed on a so-called weir wall such as a building roof, an edge wall of a balcony, or a standing wall constituting a fence. Regarding.

(Prior Art) This type of handrail is generally erected directly on the weir wall by fixing anchor fittings connected to the base of each support of the handrail to the top of the weir wall. Compared to the traditional handrails, which were installed on building rooftops, balconies, etc. with concrete roots wrapped inside the edge walls, they have the advantage of allowing more space to be used on rooftops, balconies, etc. Unlike the above-mentioned wrapped concrete, its binding strength does not directly reach the building frame due to the presence of covering layers such as the base mortar layer, waterproof layer, and finishing mortar layer on the erected surface, and it has excellent erecting strength. Because of this, it has been receiving awards in recent years.

By the way, when installing this type of handrail, stainless steel plates or aluminum are used to cover the entire length of the top of the weir wall in order to hide the anchor metal fittings from the outside and to prevent corrosion of the metal fittings and cracking of the weir wall frame due to the infiltration of rainwater. It is necessary to cover the weir wall with a long weir wall cap made of extruded alloy material with a downward U-shaped cross section. Therefore, it is necessary to integrate this weir wall cap into the handrail, but if this is connected and fixed to the base of the post in advance together with the anchor fitting, the entire outside of the anchor fitting will be covered by the weir wall cap. This makes it impossible or extremely difficult to fix the anchor fittings to the weir wall because the caps get in the way.
Therefore, in the past, when installing handrails,
A method is generally employed in which each anchor fitting is first fixed to a predetermined position on a weir wall separately from the support, and then these anchor fittings and the support are connected and fixed later.

(Problem to be solved by the invention) However, it goes without saying that the mounting position of each anchor fitting on the weir wall must be set strictly in accordance with the position of each support, while the weir wall itself is attached to the building frame when handrails are attached. It has a rough finish as well,
There are considerable differences in width and height depending on location, and there are also quite a few sloping tops and entrances and exits on both indoor and outdoor sides. Therefore, in the conventional mounting means,
When fixing the anchor metal fittings to the weir wall, match the distance between the metal fittings with the distance between the handrail supports, and use spacers etc. to align the indoor and outdoor positions and heights of the multiple metal fittings. In order to correct the inclination caused by the inclination of the top surface, the troublesome position adjustment that involves measuring the dimensions and inclination must be repeated many times, which requires a great deal of effort and time for the installation work, and the position adjustment must be completed completely. Since it was difficult to do so, there was a problem that a certain amount of wobbling was inevitable.

In view of the above-mentioned circumstances, the present invention makes it possible to perform the fixing operation very simply and reliably without requiring any mutual positional adjustment of the anchor fittings when fixing the anchor fittings to the weir wall, thereby greatly improving workability of installation. It is an object of the present invention to provide a method and device for attaching a handrail that is superior and has good attachment stability.

(Means for Solving the Problems) In order to achieve the above object, the handrail attachment method of the present invention connects the tops of a plurality of cylindrical supports and the constituent members of the handrail cap, and The base of the handrail is connected to the weir wall caps having a downward U-shaped cross section to form the main frame of the handrail, while the pillar fittings are implanted into the anchor fittings from the lower open end of each support in the main body frame. Insert the inserting rods, and temporarily fix each post fitting inserting rod to the column at the downward protruding position where the anchor metal fitting is away from the weir wall cap, place the handrail unit thus assembled on the top of the weir wall, and After fixing the anchor fittings to the weir wall, release the temporary fixing, lower the main frame, and connect and fix each support and the support rod at the position where the weir wall cap covers the top of the weir wall. It adopts a configuration characterized by the following.

Further, for the same purpose, the handrail mounting device of the present invention has a handrail cap component connected to the top of a plurality of cylindrical supports, and a weir wall cap connected to the base of the same, and the handrail cap included in each support. From the lower opening end, the support rods installed in the anchor fittings fixed to the top of the weir wall are inserted so as to be able to slide freely in the axial direction, and the weir wall caps are separated from the anchor fittings to separate each support and the support rods. The structure includes fixing means for fixing the handrail at the temporary fixing position and the handrail upright position where the weir wall cap covers the anchor metal fittings.

Therefore, in the present invention, in the above-mentioned mounting device, the fixing means at the temporary fixing position and the handrail standing position are the lower screw hole and the upper temporary fixing hole provided in the column insertion rod, and the lower part of the side wall of the column. A preferred embodiment includes a fixing bolt that penetrates from the outside and can be inserted into either of the holes.

(Function) In the method and device of the present invention, anchor metal fittings corresponding to each support are attached to the main body frame, which connects a plurality of cylindrical supports, the constituent members of the handrail cap, and the weir wall cap, through the post fitting rods. The handrail unit can be assembled by temporarily fixing it at the downward protruding position away from the wall cap.
By uniformly setting the temporary fixing position, that is, the downward protrusion length, of the anchor fittings, each anchor fitting can be prepositioned in advance with only the vertical position uniformly shifted from the original mounting position with respect to the main body frame. It becomes possible to keep it.

Therefore, to install the handrail, after placing the above unit on the weir wall and fixing each anchor fitting to the weir wall, the temporary fixings are released, and the main body frame that has been lifted is attached to the support post. This is done by lowering the support to a predetermined installation height by sliding it with the insertion rod, and then connecting and fixing the support with the support rod. Here, when fixing the anchor fittings to the weir wall, the weir wall cap is lifted upward together with the main body frame and is separated from the anchor fittings, so it does not interfere with the fixing operation, and each anchor fitting is attached to the main body. Since it is already positioned relative to the frame, there is no need to individually adjust the position, height, inclination, etc. in the indoor/outdoor direction or wall direction. All that is required is to compensate for the gap created between the two by inserting a spacer or packing.

In addition, in the device of the present invention, the means for fixing the temporary fixing position between the column and the column inserting rod and the handrail upright position are the lower screw hole and the upper temporary fixing hole provided in the column inserter, and the fixing means for the temporary fixing position of the column and the column inserting rod. With a configuration consisting of a fixing bolt that penetrates the lower part of the side wall from the outside and can be inserted into either of the holes, it is possible to easily change the fixation between the two positions by simply tightening and loosening the bolt. .

(Example) The present invention will be described below based on illustrated examples.

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 furthermore, the horizontal beams 5, 5... bridge between the supports 3, 3 at the lower positions, and the handrail cap 4 and the horizontal beams. Vertical bars 6, 6, . . . whose upper and lower ends are supported and fixed are arranged on the 5 and 5.

FIG. 2 shows an anchor fitting 7 used for attaching the handrail. Each part of this anchor fitting 7 is made of iron, stainless steel, etc., and is made by bending a single plate into a saddle shape to form a top plate part 7a and indoor and outdoor side wall parts 7b, 7.
c, and a rectangular cylindrical support insertion rod 8 is vertically planted in the center part of the top plate part 7a by welding, and the rod 8 is vertically planted along the upper surface side of the top plate part 7a in the indoor-outdoor direction. Two parallel ribs 9, 9 are fixed to both sides of the column fitting rod 8 by welding. However, both ribs 9,
The upper edge of 9 is gently sloped so that the indoor side is lower, and vertical long holes 10, 10 are bored in both side walls 7b, 7c at horizontally opposite positions, respectively. Further, the column fitting insertion rod 8 is set so that its top matches the top of the column 3 when the handrail is attached, or is slightly shorter than that, and a square nut 11 is welded to the lower part of the indoor side wall 8a. A screw hole 12a passing through the side wall 8a is provided, and a screw hole 12b is also provided at the top.

On the other hand, as shown in Fig. 3, the weir wall cap 2 is made of a long plate material with a substantially downward U-shaped cross section made of bent stainless steel plate or extruded aluminum or alloy material, and has an outer hanging wall portion 2c on the inner side. Hanging wall 2b
By making the top plate part 2a higher and gently sloping the top plate part 2a so that the indoor side is lower, draining properties are imparted. However, the degree of inclination of the top plate portion 2a of the lever matches that of the ribs 9, 9 of the anchor fitting 7. Further, the lower ends of both side hanging wall portions 2b and 2c are both bent inward in an L-shape.

The support column 3 is made of extruded aluminum or its alloy, and as shown in FIG.
a, 3a, . . . , and the inside thereof is set to a size that allows the support rod 8 of the anchor fitting 7 to be inserted thereinto. As shown in FIG. 3, a bolt insertion hole 3b is bored in the lower part of the indoor side surface of this support 3. Further, as shown in FIGS. 4 and 5, the horizontal crosspiece 5 is formed of the same extruded material as described above and has a downward U-shaped cross section, and has a plurality of ribs 5a on the inner surfaces of both side walls.
have.

When installing the handrail, first, attach the base plate material 4a of the handrail cap to the top of the plurality of supports 3, 3...
(see Fig. 4) are connected and fixed to the base of the weir wall caps 2 by passing through them and screwing the screws 13 into the screw pockets 3a, and also to the horizontal beams 5, 5.
...and the vertical bars 6, 6... to connect the main body frame of the handrail.
A', then insert the post fitting rod 8 of the anchor fitting 7 into each post 3, and insert the fixing bolt 14 inserted through the bolt insertion hole 3b of the post 3 into the screw hole 12b at the top of the post fitting rod 8. They are screwed together and temporarily fastened to produce a handrail unit A as shown in FIG. In this unit A, both ends of the weir wall cap 2 protrude from the end supports 3 by a length corresponding to 1/2 of the distance between the supports.

Next, as shown in FIGS. 3 and 7, this unit A is placed on the weir wall 1 so that each anchor fitting 7 fits over the top of the weir wall 1, and each anchor fitting 7 is placed on the weir wall 1. Attach to wall 1. In this process, the body frame
A' is in a lifted state due to the temporary fixing. Therefore, when fixing, as shown in FIG. 3, a packing 15 of a required thickness is inserted into the gap created between the top or side surface of the weir wall 1 and the anchor fitting 7.
After eliminating the gap, a through bolt 16c is passed through the weir wall 1 through the indoor and outdoor elongated holes 10, 10 of the anchor fitting 7, and nuts 16b, 16b are screwed and fastened to both ends of this bolt 16a.

After the above fixing is completed, insert the fixing bolt 14 into the screw hole 1.
2b and release the temporary fixing between each support 3 and the support insertion rod 8, and the lower surface of the weir wall cap 2 of the main body frame A', which had been lifted, comes into contact with the ribs 9, 9 of the anchor fitting 7. Lower the lower screw hole 1 of the column insertion rod 8, which is set in advance so that it is coaxial with the bolt insertion hole 3b of the column 3 in this lowered position.
By screwing and tightening the fixing bolts 2a, the respective columns 3 and the column fitting insertion rods 8 are connected and fixed again, and the installation of the unit A is completed.

It should be noted that between the adjacent units A and A, only the weir wall cap 2 is connected, creating a space between the supports 3 and 3. As shown in Figure 8, this empty space is for the handrail cap 4
A, a connecting unit B assembled with horizontal bars 5, vertical bars 6, 6, . The connection between units A and B is shown in Figures 4 and 5.
As shown in the figure, a connecting plate 17 with a U-shaped groove is fitted to the end of the horizontal beam 5 of unit B using the slits formed in the ribs 5a on both sides, and the end of unit A is fitted in advance. This is accomplished by fitting the U-shaped groove of the connecting plate 17 over the protrusion of a connecting bolt 19 fixed to the support column 3 via a nut 18a, and screwing and tightening the nut 18b. Incidentally, this connection structure is also adopted for the connection between the support column 3 and the horizontal beam 5 in the unit A. In addition, to connect the units A and B on the side of the handrail cap 4, the upper plate 4b of the cap 4, which has an inverted U-shaped cross section, is passed between both units A and B to connect the fourth unit A and B.
This is done by fitting it into the bottom plate material 4a as shown in the figure.

However, after the installation of both units A and B is completed,
As shown in FIG. 4, finishing such as painting a finishing mortar layer 20 and filling a watertight caulking material 21 on both the indoor and outdoor sides of the weir wall 1 may be performed. In addition, 22
is a waterproof sheet pasted from the top of the weir wall 1 to the indoor side.

In the above embodiment, the connecting unit B is used, but the units A may be directly connected to each other. Further, the design of the anchor fitting 7 can be changed in various ways other than those shown in the example. For example, the part having the post-fitting insertion rod 8 and the part fixed to the weir wall 1 may be made into separate members and the two parts may be connected. The structure may be such that the portion 7a is sloped and the ribs 9 are provided on the lower surface side of the portion 7a. Therefore, the fixing means of this anchor fitting 7 can be changed as appropriate along with its structure depending on the material of the weir wall, the required fixing strength, etc. For example, when the weir wall 1 is made of RC (reinforced concrete), the Through bolt 16a shown in FIG.
Instead of the fixing means for ALC (lightweight foamed concrete) using ALC (lightweight foamed concrete), it is possible to use fixation using foundation studs 23 such as hole-in anchors or dry pits as shown in Fig. 9. On the other hand, the bolt hole for temporarily fixing the post fitting insertion rod 8 may be a simple through hole instead of the screw hole 12b. Furthermore, in the present invention, it goes without saying that various design changes can be made to the detailed structures of members other than those shown in the examples.

(Effects Unique to the Invention) According to the method and device for attaching a handrail according to the present invention, when the handrail is erected directly on the weir wall via the anchor fittings at the base of each column, the handrail can be attached to the weir wall. It can be installed as a unit including the anchor metal fittings, and when the anchor metal fittings are fixed to the weir wall, there is no operational hindrance due to the weir wall cap that ultimately covers the anchor metal fittings, and the complicated position adjustment of the anchor metal fittings is not required. This eliminates the need for handrails that are extremely easy to operate and have excellent mounting stability.

In addition, in the device of the present invention, the means for fixing the temporary fixing position between the column and the column inserting rod and the handrail upright position are the lower screw hole and the upper temporary fixing hole provided in the column inserter, and the fixing means for the temporary fixing position of the column and the column inserting rod. By adopting a configuration consisting of a fixing bolt that penetrates the lower part of the side wall from the outside and can be inserted into either of the above-mentioned holes, the fixing conversion between the above-mentioned two positions can be easily performed simply by tightening and loosening the above-mentioned bolts. It becomes possible.
