[0006]

[Means for Solving the Problems] As a pillar of a building frame,
When a concrete-filled steel pipe column is employed, the filling of concrete into the steel pipe material for the column is generally performed on site. The steel pipe is exactly a vertical pipe, and the present invention uses the steel pipe for the concrete-filled steel pipe column for transporting concrete upstairs.

[0007] That is, the above problem is that the pillars of the building frame are
It consists of a concrete-filled steel pipe column filled with concrete inside the steel pipe material.The steel pipe material constituting this column is provided with a concrete supply port to the upper floor, and the steel pipe material is filled with concrete. The problem is solved by a method for transporting concrete to a building floor, wherein concrete is supplied to the floor through the concrete supply port.

According to this transportation method, it is possible to eliminate the necessity of installing a vertical pipe dedicated to concrete transportation in the building frame. Therefore, reinforcement, removal of the vertical pipe after the construction is completed, and repair of the floor slab are also required. The concrete can be easily transported upstairs without any trouble in construction, for example, it becomes unnecessary.

[0009] Moreover, the concrete transport to the floor and the concrete filling to the steel pipe material can be performed continuously and continuously, and the efficiency of the construction of the building can be improved.

In the above-mentioned transportation method, it is preferable that a concrete pipe connection port is provided in the steel pipe at the downstairs, and the inside of the steel pipe is filled with concrete through the connection port. By doing so, it is possible to transport concrete upstairs simply by connecting a pipe from a concrete supply source to this connection port.
