DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for erecting a handrail support on a parapet.

[0002]

2. Description of the Related Art Parapets are constructed as concrete barriers on the rooftops and verandas of buildings. Metal caps are attached as caps on the parapets. Is provided. The handrail generally has an assembling structure in which a handrail frame is provided at an upper end of a support, a horizontal rail is provided at a lower end, and a vertical rail is arranged between the handrail frame and the horizontal rail.

Conventionally, in order to erect the handrail support, an anchor plate is fastened and fixed to a parapet under an heddle by an anchor bolt, but the support is previously screwed to the anchor plate.

[0004]

According to the conventional method of erecting a handrail support, the support penetrates through the cap and the lower end of the support is fixed under the support. And, as an operation procedure, since the anchor plate is previously attached to the lower end of the column, the attachment of the stake is irrationally retrofitted because of the operation of fastening the anchor plate to the parapet. In other words, there is a disadvantage that the shed is attached after the support is erected.

[0005] In this regard, if a cap is inserted through the support in advance, it becomes very difficult to fasten the anchor plate thereunder. Therefore, the support is erected without the support being inserted, and the support is erected. Handrails could not be preliminarily assembled at the factory in order to insert the caps into it after installation.

The present invention has been made in view of the above-described circumstances,
Even if the handrails are assembled together with the Kasagi, it is possible to provide a method for erecting the handrail supports, which makes it very efficient to install the handrails on site because the supports can be erected. And

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an anchor plate fixed to a parapet with an anchor bolt and a cap holder made of an extruded aluminum member, which are previously integrated by caulking. The base plate at the lower end of the handrail support is screwed into the stake holder from the top of the stake, and the screw is screwed into the sash holder through the attachment hole drilled in the base plate. A method of erecting a handrail support for forming a hole is configured.

The handrail is temporarily fixed to the base plate at the lower end of the column with a screw in advance, and a screw hole for accommodating an exposed portion of the screw is formed in the elongate hole in the lateral direction. And Kasagi in advance manufacturer (factory)
The so-called factory unit type set on the side can be shipped, and the unit type can be easily attached to the parapet at the installation site via the cap holder and the anchor plate. In addition, mutual adjustment of the position of the cap and the strut becomes possible.

[0009]

[Function] Since the cap holder is integrated with the anchor plate by caulking, a very strong fixing state to the parapet can be obtained. Since the cap holder is made of aluminum suitable for forming a tap hole for a screw, the base plate at the lower end of the support can be screwed to the cap holder at an appropriate position from above the cap.

When the base plate is screwed to the coping holder, the coping is also screwed at the same time, and it is not necessary to retrofit the coping, so that the handrail can be assembled in advance on the support.

[0011]

Next, an embodiment of the present invention will be described with reference to the drawings.

The drawings show an embodiment, and when a handrail support 3 is erected on a parapet 1, an anchor plate 5 and a cap holder 7 serving as an erected substrate of the support 3 are integrated in a factory. Be transformed into In addition, the handrail P is assembled together with the kasagi 9 and brought to the site in the assembled state.

The anchor plate 5 is formed by pressing a metal plate, and is formed with connecting flanges 11, 11 which are bent up and down at both front and rear ends.
A plurality of notches 12, 12, 12 for removing 11;
Elongated holes 13, 13 for screwing to the parapet 1 are provided at both side ends. Further, a pair of left and right screw holes 15 is formed inside the long holes 13.

The cap holder 7 is formed by cutting and processing a substantially channel-shaped extruded aluminum material shorter than the anchor plate 5, and has a shape inclined to the indoor side because the upper surface is in close contact with the cap board 9. I have. In the cross-sectional shape, grooved legs 17, 17 for holding the coupling flanges 11, 11 of the anchor plate 5 are formed at both front and rear ends, and a holding leg 19, which contacts the upper surface of the anchor plate 5, is vertically provided at a central portion therebetween. . At both front and rear ends, hanging pieces 21 and 21 for hanging the cap 9 are vertically provided. Then, a pair of left and right screw holes 22, 22 is formed in the upper surface in close contact with the skirt 9 as long holes in the longitudinal direction of the skirt 9.

As for the connection between the anchor plate 5 and the cap holder 7, the countersunk screws 23, 23 penetrate the upper face of the cap holder 7 and are screwed into the screw holes 15, 15, and the grooved legs 17, 17 from the back face. Is crimped in the notches 12, 12, and 12, and the crimped portions 13 are formed respectively. Thus, the connection between the connecting flanges 11, 11 and the grooved legs 17, 17 is maintained.

The handrail P has a handrail frame (not shown) erected at the upper end of the column 3, and a vertical bar 27 is arranged between the handrail frame and the horizontal bar 25 at the lower end. A cap 9 is attached to the lower end in advance.

As shown in FIG. 4, the base plate 31 is welded to the lower end of the core material 29 of the support 3 and the base plate 31 is sandwiched with the packing 33 therebetween.
Is screwed to the Kasagi 9. Bolts 35 and nuts 37 are used for the screws, and the nuts 37 are movably housed in the screw holes 22 of the cap holder 7. Attachment of the cap 9 is temporary fixing. Finally, after the positions of the support 3 and the cap 9 are adjusted by the screw holes 22, the base plate 31 is screwed to the cap holder 7.

The column 3 is screwed to the cap holder 7 in such a manner as to be integrated with the handrail P. The procedure is as follows: after adjusting the position of the column 3 with respect to the skirt 9, the mounting holes 39, 39,.
Then, the through hole 43 of the mounting screw 41 is drilled in the skirt 9, and the screw hole 45 is drilled in the skirt holder 7. After the handrail P is installed, the split cap 4 is attached to the lower end of the support 3.
6, 46 are assembled so that the base plate 3
1 is nicely coated.

[0019]

As described above, according to the present invention, there are the following excellent effects.

After the handrail is assembled together with the cap, the handrail support can be erected on the parapet, so that the setup of the handrail is greatly improved and the work efficiency is greatly improved. be able to.

The base plate at the lower end of the column is screwed to the sash holder. The sash holder is integrated with the anchor plate by caulking and is made of aluminum suitable for forming screw tap holes. The support can be strongly supported.

In connection with the screwing of the base plate, the cap can be strongly attached so that the cap is sandwiched between the cap and the holder.

If a cap is temporarily fixed to the base plate at the lower end of the column with a screw in advance, and a screw hole for accommodating an exposed portion of the screw is formed in the cap holder in a laterally elongated hole (claim 2). In addition to being able to ship what is called a factory unit type in which the above-mentioned handrails and kasagi are set in advance by the manufacturer, it is possible to adjust the mutual position between the kasagi and the support, so that the handrails must be installed. It will be easier.
