SOLUTION: A cantilever, which is raised obliquely with a foundation as a fulcrum, is installed as an inclined support, and the inner and outer forms of the oblique body are supported by the inclined support, and concrete is struck between the inner and outer forms. This is a method of constructing an oblique body.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a skeletal structure such as a spectator seat in a stadium.

[0002]

2. Description of the Related Art Conventionally, in order to construct a skeletal structure, a scaffold was assembled and constructed over the entire area outside the sloping structure. This scaffold was to support the full load of formwork, shoring, and cast concrete.

[0003]

The above-described conventional method for constructing a slanted skeleton has the following problems. <B> To support the entire load on the wall rising up diagonally, a huge amount of scaffolding and support was required. <B> Assembly and disassembly of this scaffold required a lot of trouble and huge temporary costs, and assembly and disassembly involved danger.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and does not require any scaffolding to be installed outside the diagonal frame. The purpose is to provide a construction method.

[0005]

In order to achieve the above object, a method for constructing a diagonal skeleton according to the present invention is to install a cantilever, which is raised obliquely with a foundation as a fulcrum, as an inclined column. The present invention is characterized by a method of constructing an oblique body, in which the inner and outer forms of the oblique body are supported by the inclined supports and concrete is poured between the inner and outer forms.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

<A> Installation of inclined supports. The base end of a pillar such as H-steel is implanted in the foundation of the slanted skeleton 3 and supported by a cantilever.
As the foundation 2 for implanting the base end of the lowermost strut 1, a foundation 2 constructed in the ground is used. However, when constructing the upper floor of the diagonal frame 3, the beams and the like of the lower floor should be
Used as a support base 2 for As shown in FIG. 2, the position of the inclined support 1 is determined by the inclined frame 3 to be constructed next time.
Inside.

<B> Support for the formwork. In order to construct the slanted concrete frame 3, the form 4 is arranged on the inner and outer surfaces of the frame 3, and concrete is poured into the inside of the frame 4. For this purpose, the inner and outer formwork 4 of the slanted skeleton 3 are supported by the inclined supports 1 implanted in the foundation 2 in a cantilever state. To fix the form 4, one end of the form 4 supporting steel rod 5 is welded or bolted to the inclined support 1,
The other end of the supporting steel bar 5 is penetrated through the form 4 to perform the process. Prior to fixing the outer formwork 4 and the inclined support 1, a reinforcing bar is assembled inside the outer formwork 4. Finally, insert the inner formwork 1
Stepwise lean on the inclined column 1 and support the steel column 5 with the inclined column 1
Go to fixed. When the outer and inner forms 4 are securely fixed to the inclined column 1, concrete is poured into the inside thereof.

<C> Another embodiment. The construction method described above has a configuration in which the inclined support 1 is positioned inside the oblique skeleton 3. However, depending on the case, as shown in FIG. 3, it is also possible to arrange the oblique body 3 at the position where the front surface of the inclined column 1, that is, the inner flange of H steel is exposed from the surface of the oblique body 3 to be constructed next time. With this arrangement, after the concrete is hardened and the inner formwork 4 is disassembled, the inner flange of the inclined column 1 is exposed on the inner surface of the frame 3. For this purpose, the interior and the curtain wall can be attached later using the exposed portion. Alternatively, a method is employed in which a horizontal pipe is engaged with the upper surface of the lower flange of the inclined column 1 and the outer (lower) formwork is suspended by taking a supporting force on the horizontal pipe to cast concrete. can do. Then, the web and the flange of the H steel are exposed on the inner side of the oblique body 3. Also in this case, the scaffold can be fixed to the exposed H steel, and can also be used as a base material for an interior material.

[0010]

[Effect of the present invention] Since the method of constructing an oblique body according to the present invention is as described above, the following effects can be obtained. <B> Since the inclined column 1 supports the entire weight, the construction can be performed without making a huge scaffold outside the oblique frame 3. Alternatively, even if a scaffold is installed, it is not necessary to receive the full load, so a small one is sufficient. <B> Since the inclined column 1 can be installed before concrete casting, the internal scaffolding, passage, and temporary support can be easily attached using the inclined column 1. In addition, it can be used as a ruler for positioning, which is indispensable for unstable work in an inclined state. <C> A method of arranging the inclined column 1 outside the frame 3 is also conceivable. However, according to the method of the present invention, since the inclined column 1 is arranged inside the frame 3, the disassembly work of the inclined column 1 and the support works is not required as compared with the case where the inclined column 1 is arranged outside, and the method is very economical. <D> If a part of the inside of the inclined column 1 is exposed to the inside of the frame 3, it can be used as a mounting base for an interior member and a curtain wall.
