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 installed directly on the weir wall by fixing to the top of the weir wall an anchor fitting connected to the base of each support of the handrail. In contrast to the traditional handrails, which were installed on building rooftops, balconies, etc. with concrete roots wrapped inside the edge walls,
It has the advantage of widening the usable space on rooftops, balconies, etc., and, like the above-mentioned wrapped concrete, its cohesive strength is enhanced by the presence of coating layers such as the base mortar layer, waterproof layer, and finishing mortar layer on the building structure. Because it has excellent standing strength without the disadvantage that it is not directly comparable to
In recent years, it has been receiving awards.

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. , the caps get in the way, making it impossible or extremely difficult to fix the anchor fittings to the weir wall.

Therefore, in the past, when installing handrails, each anchor metal fitting was first fixed to a desired position on the weir wall separately from the support, and then there was a means for connecting and fixing these anchor metal fittings and the support. Generally adopted.

(Problem M 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 when the handrail is attached is Like the frame, it has a rough finish, and there are considerable differences in width and height depending on location, as well as a sloping top surface and quite a few entrances and exits on both indoor and outdoor sides. For this reason, in the conventional mounting means, when fixing the anchor metal fittings to the weir wall, the distance between the metal fittings is made to match the distance between the handrail supports, and spacers etc. are used to extend the position of the anchor metal fittings in the indoor and outdoor directions. In order to align the height and correct the inclination due to the slope of the top surface of the weir wall, the troublesome position adjustment that involves measuring dimensions and inclinations had to be repeated many times, and the installation work required a great deal of labor and time. Furthermore, since it is difficult to completely adjust the position, there is a problem in that a certain amount of wobbling is inevitable.

In view of the above-mentioned situation, the present invention has been developed to provide an object in which when fixing the anchor fittings to the weir wall, there is no need to adjust the mutual position of the anchor fittings, and the fixing operation can be performed very easily and reliably, thereby providing extremely excellent installation workability. It is an object of the present invention to provide a hand-held mounting method and a mounting device that also provide good mounting 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 body frame, and connect and fix each support and the support column 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 includes a handrail cap component on the top of a plurality of cylindrical supports,
Each of the weir wall caps is connected to the base of the weir wall, and a strut insertion rod installed in an anchor fitting fixed to the top of the weir wall is inserted into each support from the lower open end thereof so as to be slidable in the axial direction. Adopts a structure comprising fixing means for fixing each support and the branch insertion rod at a temporary fixing position where the weir wall cap is spaced from the anchor fitting and at a handrail upright position where the weir wall cap covers the anchor fitting. It is.

Therefore, in the present invention, in the above-mentioned mounting device, the fixing means at the temporary fixing position and the handrail upright position are the lower screw hole and the upper temporary fixing hole provided in the column insertion rod, and the side wall of the column. A preferred embodiment includes a fixing bolt that penetrates the lower part 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 support inserting rods. Since the handrail unit is assembled by temporary fixing at the downward protruding position away from the weir wall cap, by uniformly setting the temporary fixing position of the anchor fittings, that is, the downward protruding length, each anchor fitting can be attached to the main body frame. On the other hand, it is possible to predetermine the position in advance so that only the vertical position is uniformly shifted from the original mounting position.

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 lifted main body frame is attached to the support and support rod. This is done by lowering the column to a predetermined installation height by sliding it, and then connecting and fixing the column and the column insertion rod.

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 frame. Since it is already positioned against the weir wall, 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 resulting gap by inserting a spacer or packing.

In addition, in the device of the present invention, the means for fixing the temporary fixing position of the column and the column insertion rod and the handrail upright position are the lower tapped hole and the upper temporary fixing hole provided in the column insertion rod, and the temporary fixing hole of the column and the column insertion rod. With a structure 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, the repositioning can be easily performed by simply tightening and loosening the bolt. It becomes possible.

In addition, this connection structure is also adopted for the connection between the column 3 and the horizontal beam 5 in the unit A. Furthermore, to connect the units A and B on the side of the handrail cap 4, the top plate 4b of the cap 4, which has an inverted U-shaped cross section, is inserted into the bottom plate 4a between the two units AB as shown in FIG. carried out by

After the installation of both units A and B is completed, as shown in Fig. 4, finishes such as painting a finishing mortar layer 20 and filling watertight caulking material 21 are applied to both the indoor and outdoor sides of the weir wall 1. That's fine. Note that 22 is a waterproof sheet pasted from the top surface of the weir wall 1 to the indoor side surface.

In addition, in the above-described embodiment, the connecting Unisol I-B is used, but a structure in which the units A are directly connected to each other may also be used. 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 l may be made into separate members and the two parts may be connected. The portion 7a is sloped and a rib 9 is provided on the lower surface side of the portion 7a.
However, 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, if the weir wall 1 is made of RC ( (reinforced concrete), Fig. 3,
Instead of the fixing means for ALC (lightweight foamed concrete) using the through-hole holes 6a shown in FIG. 4, fixing using foundation planting rods 23 such as hole-in anchors or dry pits as shown in FIG. 9 can be adopted. 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.
