Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail wall formed on the outer periphery of the roof of a building, and more particularly to a handrail wall and a method of constructing the same that can reduce falling objects during construction.

[0002]

2. Description of the Related Art Conventionally, in general, a handrail wall (parapet) formed on the outer periphery of the roof of a building is constructed of, for example, plywood veneer on the outer surface of the handrail wall and the inner surface of the handrail wall. In a state where a pair of mold plates are erected and the intervals between these mold plates are maintained by a separator metal object,
This is done by placing concrete between these formwork plates, curing the concrete, and then removing the formwork plates.

[0003]

However, in such a conventional construction method, there is a risk that, for example, the separator metal fittings may drop when assembling the form plate made of plywood veneer, and the form plate may be removed. At times, there was a problem that concrete pieces or the like might fall.

The present invention solves the above problems, and an object of the present invention is to provide a handrail wall and a method of constructing the handrail that can significantly reduce the fall of metal fittings, materials, etc. during construction. To do.

[0005]

The handrail wall of the present invention is a concrete handrail wall formed on the outer periphery of the roof of a building, and a corrugated unevenness is formed on the outer surface of the main body of the handrail wall made of concrete. A steel plate is integrally fixed to the concrete.

According to the method of constructing a handrail wall of the present invention, a corrugated sheet steel plate having corrugated irregularities is erected on a portion which is an outer surface of the handrail wall formed on the outer periphery of the roof of the building, and the corrugated steel sheet is formed. A formwork plate is erected on the inner surface of the inner handrail wall, and concrete is placed between the corrugated steel plate and the formwork plate.

[0007]

In the handrail wall of the present invention, when pouring concrete, a corrugated steel plate having corrugations is used as an outer form plate. To be a part.

In the construction method of the handrail wall of the present invention, concrete is placed between the corrugated steel plate and the form plate, and after the concrete is cured, only the form plate is removed and the corrugated steel plate is not removed. It will be part of the handrail wall as it is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of the handrail wall of the present invention, and in the figure, reference numeral 11 indicates a steel frame column arranged on the uppermost floor of the building.

A steel frame beam 13 is horizontally supported on the upper end of the steel frame column 11, and a rooftop floor 15 made of concrete is formed on the steel frame beam 13. In this embodiment, the handrail wall (parapet) 1 is provided along the outer periphery of the roof of the building.
7 are formed.

The handrail wall 17 is formed by integrally fixing a corrugated steel plate 21 having corrugations to the outer surface of a handrail wall body 19 made of concrete. In addition,
In this embodiment, a keystone plate is used as the corrugated steel plate 21.

The handrail wall 1 is provided outside the handrail wall 17.
An outer wall member 23 made of precast concrete is arranged at a predetermined distance from 7. This outer wall member 2
3 is supported by a fastener 25 fixed to the handrail wall 17, and the upper end bent portion 27 is supported on the upper surface of the handrail wall 17.

On the side of the handrail wall 17 on the roof floor 15,
A mortar floor 29 for waterproofing is formed. The handrail wall 17 described above is constructed, for example, as described below by an embodiment of the method for constructing the handrail wall of the present invention.

First, as shown in FIG. 2, the parent ropes 31 are erected on the steel beam 13 at intervals of, for example, 1800 to 2200mm, and the parent ropes 33 are connected to the parent ropes 31. The corrugated steel plate 21 is fixed to the steel column 31 by bolts, welding or the like.

Here, the master rope 33 is for hooking a safety belt to prevent a fall when the steel frame is constructed. After this, the construction of the steel frame was completed, and further,
After the rooftop floor 15 and the like are constructed, a form plate 35 made of, for example, plywood veneer is erected at a predetermined interval inside the corrugated steel plate 21.

As shown in FIG. 3, the standing of the form plate 35 is such that, for example, a pipe 37 having a quadrangular cross section is placed inside the corrugated steel plate 21 at a predetermined interval.
It is done by fixing.

After this, the hole 3 formed in the corrugated steel plate 21.
Fasteners 25 are fixedly arranged inside 9 and concrete is poured between the corrugated steel plate 21 and the form plate 35.
Then, after curing the concrete, the outer wall member 23 made of precast concrete is arranged so as to cover the outer surface and the upper surface of the handrail wall 17, and finally, the pipe 37 and the form plate 35 are removed.

In the handrail wall and the construction method thereof, however, the corrugated steel plate 21 is used as the outer form plate when pouring concrete, and the corrugated steel plate 21 is used as the handrail wall 1.
Since it is left as it is as the component part of 7,
It is no longer necessary to remove the formwork plate arranged outside the handrail wall after the concrete is set and cured, and it is possible to greatly reduce the risk of falling concrete strips and the like compared to the conventional case.

The corrugated steel plate 21 is used as the outer form plate because the corrugated steel plate 21 is formed in a corrugated shape, so that the corrugated steel plate 21 is firmly fixed to the concrete by pouring the concrete and formed in the corrugated shape. Therefore, it is relatively rigid and does not deform like a flat plate.

Further, in the above-mentioned method of constructing the handrail wall, in the state where the master rope support 31 is erected on the steel beam 13 and the master rope 33 is connected to the master rope support 31, the corrugated steel plate 2 is attached to the master rope support 31.
Since No. 1 is attached in advance, this corrugated steel plate 21 can be effectively used as a handrail during the assembly of a steel frame, a flying prevention fence, and the like.

Furthermore, in the above-mentioned method of constructing the handrail wall,
Since the corrugated steel plate 21 is erected by fixing the corrugated steel plate 21 to the main ropes 31, and the mold frame plate 35 is erected by fixing the mold frame plate 35 to the pipe 37, a metal fitting such as a separator metal fitting. Is unnecessary, and it is possible to reduce the risk that a metal object or the like will fall when assembling the mold plate as in the conventional case.

In the embodiment described above, the corrugated steel plate 2 is used.
Although the example in which the keystone plate is used as 1 has been described, the present invention is not limited to such an example, and it goes without saying that a corrugated steel plate such as a deck plate may be used.

[0023]

As described above, in the handrail wall and the method for constructing the same of the present invention, a corrugated steel plate is used as the outer form plate when placing concrete, and the corrugated steel plate is used as a component of the handrail wall. Since it is left as it is, there is an advantage that falling of metal fittings, materials, etc. at the time of construction can be significantly reduced as compared with the conventional one.
