About the.

[0002]

2. Description of the Related Art Conventionally, in a steel frame structure or a reinforced concrete structure, generally, both columns and beams are of the same type.

[0003]

SUMMARY OF THE INVENTION In a conventional structure,
Since the beam has a large influence on its bending due to its own weight, and it can secure sufficient strength with a steel structure, it was desirable to use a steel structure with a light weight. In addition, a reinforced concrete structure was desired for the pillar portion in consideration of the strength such as compression. When the advantages of both structures are adopted, and both the steel frame structure and the reinforced concrete structure are mixed, the strength inherent in the material of the beams and columns cannot be sufficiently exhibited, and There was a problem that force was not transmitted well from the beam to the column.

[0004]

The present invention solves the above-mentioned problem by using a beam having a fixing member and supporting and connecting the beam by using a beam supporting member and a connecting member.

That is, the present invention relates to a reinforced concrete column.
And a steel frame-based structure, comprising: a steel plate having a predetermined height at a position where a column is to be built ; and a support plate on an upper surface.
The beam support members having the beam are respectively erected, and the beam support members are supported.
The board consists of upper and lower flanges and a web,
Form a notch that is notched so that the joining end of
It bridged a predetermined number of forms a beam, facing the notch of the adjacent beams
Then, the webs of adjacent beams are connected to each other via a reinforcing plate, and the lower flange of the beams and the beam supporting member are connected to each other .
And a supporting plate connected with bolts and nuts, the above beam support member, placing a connecting member for attaching the beam support member for the next floor, the support plate and the beam which is provided at the lower end of the connecting member Up
Connect the flange with bolts and nuts , where the beam is
Fix the fixing member inside the pillar to be built in advance and near the surface
Fixed, or after connecting the beams, pillars of the planned construction
A fixing member is fixed inside and near the surface , and then a column main reinforcing bar and a column band reinforcing bar are arranged at the column building scheduled position and connected to each other to form a predetermined column forming formwork. After the temporary construction, concrete is poured, and the support member and the
A method of constructing a column and a beam , wherein a joint portion of a beam tip including a nut and a nut is buried in the concrete.

In the above, the connection between the adjacent beams is performed by connecting the web of the beam to a reinforcing plate bent in an L-shape in a plane.
And the connection of the upper and lower flanges of the beam is supported
It is fixed through a plate, and the space between adjacent beams is
Fixing the shroud having a planar shape along the outer periphery of the fixed pillars
This is a method of constructing columns and beams .

[0007] The beam supporting member in the above can prevent the beam from shifting until concrete is cast, is made of a material shape that can withstand the load of the concrete after casting, and has one shear force applied to the column after the concrete is solidified. It is desirable to make the material shape that can bear the part. In the above, the side surface of the connecting portion of the beam can be reinforced. In this case, for example, when an H-shaped steel material is used for the beam, the reinforcing member is reinforced so as to increase the thickness of the web of the connecting portion. This is performed by welding the plates. Further, the means for fixing the shroud plate in the above refers to a flange or the like having a bolt hole for attachment to a steel beam.

[0008]

Since the beam is erected on the beam supporting member, the end of the beam can be embedded in a reinforced concrete column. In addition, since the connecting member is installed on the beam, the beam supporting member for the next floor can be connected. Further, since the fixing member is provided on the beam, the beam is firmly fixed in the concrete column. Further, since the flat L-shaped reinforcing plate is used for connecting the beams, the adjacent beams can be easily connected and the beams are strongly connected to each other. Also,
Since the side surface of the connecting portion of the beam is reinforced, the strength of the portion can be increased with a small amount of reinforcement, and the force can be transmitted effectively.
