Description

Concrete charge tools for steel pipe pillars {Concrete charge tools for the steel pipe}

The present invention relates to a concrete charger for steel pipe pillars, and more particularly, the filling pipe connected to the pump head and hose of the concrete mixer is hung on the boom of the tower crane and poured into the steel pipe pillar to pour concrete into the steel pipe pillar. By installing a plurality of high frequency vibrators at the bottom of the filling tube to increase the filling density so that no gaps are generated during the filling process, and by installing the camera and lighting together, the filling process inside the steel tube pillar can be checked in real time. Relates to a concrete charger.

Conventional concrete-filled steel pipe column was constructed by the injection method using a concrete bucket and the method of processing the pipe hole in the lower part of the pillar and press-fitted from the bottom. The intrinsic and fireproof performance of concrete-filled steel pipes has been proven through long-term verification, but they are not widely used due to the inefficiency of concrete filling.

But nowadays, the pump head of the concrete mixer is rising like a tower crane in the upper part of the building. Therefore, the concrete bucket becomes unnecessary. Indentation under the column was also difficult to install. Since there are many obstacles that interfere with the concrete filling inside the column, there is a problem in that the load is applied when the bottom indentation method is applied. In addition, there was a problem in the construction plan because the pillars of several floors were to be cast at once, and the blind area of the narrow space had a problem that the concrete pouring could not be visually confirmed.

The present invention was developed in view of the conventional problems, the object of the present invention is to pour the filling pipe connected to the pump head and hose of the concrete mixer on the boom of the tower crane into the steel pipe pillar to pour concrete into the steel pipe pillar However, by installing a plurality of high-frequency vibrators at the bottom of the filling tube to increase the filling density so that no gaps are generated during the filling process, and by installing the camera and lighting together, the filling process inside the steel pipe pillar can be checked in real time, thus enabling precise construction. To provide a concrete charger for steel pipe pillars.

To this end, the present invention is provided with a filling pipe that enters from the top of the steel pipe pillar to fill the concrete inside the steel pipe pillar, the filling pipe is provided with a connecting rod at the top, the connecting rod to the pump head and hose of the concrete mixer A pump hose connector to be connected is rotatably provided in left and right and front and rear sides, and the connecting rod is connected to the boom of the tower crane by a wire so that the filling pipe is elevated in the inside of the steel pipe column.

According to the present invention, since the concrete is directly poured into the steel pipe pillar, the construction period is shorter and structurally stable than when manufacturing a pillar using a conventional formwork. The present invention is intended to contribute to the widespread distribution of such a steel pipe column, the filling pipe which can directly fill the concrete in the upper portion of the steel pipe column is positioned by the tower crane can be filled with concrete inside the steel pipe column where necessary. .

In particular, since a plurality of high-frequency vibrators are installed at the lower end of the filling tube, there is an effect of filling the voids by shaking the concrete in the process of pouring high-strength concrete. In addition, the upper part of the filling pipe is provided with a connector that is connected to the pump head and the hose of the concrete mixer, so that the concrete can be continuously press-poured inside the steel pipe pillar. And since the filling tube is equipped with lighting and camera, the inside of the steel pipe pillar can be checked by a monitor in real time from the outside, so that the presence or absence of voids can be checked during the concrete pouring process. It can be used as a material to objectively prove the precision of filling concrete.

1 is a conceptual diagram of an embodiment of the present invention
2 is a conceptual diagram of a filling tube of an embodiment of the present invention

In an embodiment of the present invention, the steel pipe pillar 10 is a base unit having three or more heights, and the steel pipe pillars 10 are continuously set to build a desired height. On the outer circumference of the steel pipe column 10, the beam 11 of the H-shaped steel is connected to each other in a lattice shape to form a bottom layer of the building, and the steel pipe column 10 is filled with concrete.

Filling pipe 20 is provided with a diameter to enter the inside of the steel pipe pillar 10, the upper end of the filling pipe 20 is provided with a connecting rod 21 of a disc shape, the connecting rod 21 of the elliptical crane The crane boom 50 is provided with a crane hook 22 for connecting with the wire 51. And the center of the connecting table 21 is provided with a pump hose connector 23 is rotated to the left and right and front and rear by the rotary joint 24 is connected to the hose 61 of the pump head 60.

The lower outer circumferential edge of the filling tube 20 is provided with a spacing support 25 to guide the inner wall of the steel pipe pillar 10 and the filling tube 20 to fall off in a concentric circle. In addition, the lower end of the filling tube 20 is provided with a plurality of high-frequency vibrator 30 is separated from the end of the filling tube (20). The vibrator 30 is connected to a portion of the spacing holding portion 25 through the buffer cable 31, the vibrator 30 is between the outer peripheral surface of the filling tube 20 and the inner peripheral surface of the steel pipe pillar (10) It is preferred to be connected to be arranged.

And the outer circumferential surface of the filling tube 20 is provided with a light 41 and the camera 40 can be checked by the worker in real time the filling process of the concrete, it can be used as a material to confirm the state of charge to the supervisor by recording this. .

 One embodiment of the present invention configured as described above is one steel pipe pillar 10 is erected to the height of the three floors of the building, the filling pipe 20 into the bottom of the steel pipe pillar 10 to the bottom of the wire of the crane ( Using 51) to sequentially fill the filling pipe 20 while filling the concrete.

The charging pipe 20 is provided with a connecting rod 21 on the upper portion, the connecting rod 21 is provided with a pump hose connector 23 coupled to the rotary joint 24. Therefore, the pump hose connector 23 and the hose 61 are not twisted with each other in the process of moving the filling pipe 20 vertically or horizontally using the boom 50 of the crane. Since the pump head 60 is connected to the ground concrete mixer and the pipe, the concrete is supplied into the filling pipe 20 through the hose 61 through the pump head 60.

Since a plurality of high frequency vibrators 30 are provided at the lower end of the filling tube 20, the voids are not generated because the high strength concrete is shaken in the filling process to give fluidity. Since the vibrator 30 is connected to the charging tube 20 by the shock absorbing cable 31, vibration is not transmitted to the charging tube 20. In addition, since the charging process is confirmed from the outside using the camera 40, the work reliability is improved, and if the recording is performed, there is an advantage that it can be used as evidence.
