Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a length of concrete pouring pipe mainly consisting of a cylindrical pipe that guides concrete 1 supplied from one side downward. When constructing concrete 1 to JJ iiM-J downward from the position, it is generally done to install pipes in the vertical direction and guide the concrete 1 from the top to the bottom through this pipe. If is large, concrete 1 ~ will fall through the pipe at a considerably high speed due to gravity.If the falling speed of concrete 1 ~ becomes too fast, = 1 composition of concrete 1 by month (Rethane 1~.Fine bones, coarse bones) will separate, and a good concrete 1-hardened body will not be formed.Therefore, the falling speed of concrete 1- in the upper and lower piping can be suppressed by some means. There is a need to.

Conventionally, a U-shaped pipe was connected to the lower end of the upper and lower pipes, and the U-shaped pipe was prevented from standing up.
The falling speed IQ in the upper and lower pipes is suppressed by increasing the flow resistance of the concrete 1 and decreasing the discharge speed to the concrete 1. However, with this method,
Installation of the U-shaped distribution pipe at the bottom is very troublesome, and the height of this U-shaped pipe must be adjusted appropriately according to the head difference between the upper and lower pipes, the viscosity of the concrete, etc. This resulted in extremely troublesome construction. In addition, by taking this measure, the concrete 1 that was first poured into the upper and lower pipes without being filled with concrete 1 fell down the upper and lower pipes with great force and was scraped at the lower end, and the concrete 1 was poured into the upper and lower pipes without being filled. In some cases, the separated aggregates clogged the U-shaped piping, causing the piping to become blocked.

This invention solves the above-mentioned conventional problem 1j! This was done in consideration of the above, and its purpose was to
- effectively suppresses the falling speed of -, and in addition,
A simple 1 that uses the energy of falling onto concrete to increase the effect of remixing concrete.
Our objective is to provide a pipe drum stand for concrete 1 to 74 construction.

In order to achieve the above object, the present invention provides a strip plate having a width approximately equal to the inner diameter of the inner diameter of the cylindrical tube disposed in the vertical direction. It is characterized by a twisted kneading plate formed by twisting it into a shape.

Examples of the present invention will be described below based on the drawings.
This will be explained in 11.

FIGS. 1 and 2 show the structure of an embodiment of a piping device for pouring into concrete 1 according to the present invention. This piping device is mainly composed of a cylindrical pipe 10 (14). This cylindrical pipe 10 forms a part of the above-mentioned butt piping, and is inserted and connected in series at appropriate positions in the upper and lower piping.

In the piping device of the present invention, two twist plates 20 and 30 are attached to the cylindrical pipe 10. The twisting kneading plate 20 is formed by twisting a strip-shaped steel plate with a width approximately equal to the inner diameter of the cylindrical tube 10, so the twisting angle is approximately 9.
It is at 0°. In other words, the upper edge 22 and the 'F edge 24 of the torsional kneading plate 20 form approximately 90 degrees. This one
b; The twisting kneading plate 20 is inserted approximately in the center of the inside of the circular case 10, and is twisted (fixed by welding or rivets, etc. with both side edges in contact with the inner surface of the cylindrical tube 10).
1. Another twisting kneading plate 30 is formed exactly the same as the above twisting kneading plate 20, and is made of Cl-3. Strip-shaped steel plates with a width approximately equal to the inner diameter of the cylindrical tube 10 are placed above and below it. Both edges 32 and 3'l are twisted to look like 906. This torsion kneading plate 30 has the above-mentioned torsion i! inside the cylindrical tube 10. The two kneading plates 20 and 30 are inserted into the lower part of the kneading plate 20 and fixed by welding or by a grinder l-'r''. The lower edge 2I41 of the kneading plate 20 and the twisted 1IlPli plate 30
The upper edges 32 of the two are perpendicular to each other.

As mentioned above, a twisted d-column plate 20.30 is installed inside the r'J i:j pipe 10, and this serves as a barrier for the concrete 1- flowing inside. Concrete 1~
While suppressing the falling speed of the concrete, it gives rotational motion to the concrete. Therefore, it is not just that the flow resistance inside the pipe increases (), but that the concrete is remixed as it passes through this pipe, and separation of concrete 1 to +A will hardly occur. The effect of J in the above embodiment becomes more pronounced than that of J because the two twisting kneading plates 20 and 30 of the sea urchin are arranged in a row.

FIG. 3 is an explanatory diagram of the concrete 1 to 11 type E using the concrete piping device of this invention. In Fig. 3, reference numeral 1 designates a piping device for installing concrete pipes 1 to 4'J of the present invention constructed as described above. It is inserted in the middle of ゜4.4, and together constitutes the upper and lower piping. A flexible hose 5 for pouring is connected to the lower end of this upper and lower piping, and concrete 1 to a pump 7 are connected to the upper end via a flexible hose 6.

The concrete sent out from the concrete bomb 7 passes through the flexible hose 6 and is supplied to the upper part of the lower pipe, where it falls.

At that time, the piping device 1゜1 of the present invention inserted into the 2m pipe suppresses the falling speed of the concrete 1~, and converts the falling energy of the concrete 1~ into re-kneading energy, so that the concrete 1~ configuration b) While the Δ material is being kneaded, it falls down with almost no separation. Then, it is discharged from the flexible hose 5 and installed.

In addition, - in the above embodiment, there are two circular fi 2 pipes 10 in one tree.
Although two twisting kneading plates 20 and 30 are installed ()C, the present invention is not limited to this, and only one twisting kneading plate is used.
Cb may be used, or a larger number may be used. A good kneading effect can be obtained by using a plurality of twisting kneading plates and crossing them with each other as in the previous embodiment, but it is not necessary to arrange them in one circular pipe. In other words, by installing only one twisting kneading plate and connecting two cylindrical tubes, the same effect as in Fig. 1 can be obtained (q4)
That is -C monkey. Maruko opened many twisting kneading boards (
), the direction of twist must be alternated.

Moreover, the separation of the structure 44 by the free I3 of the concrete 1 to 1 occurs in an unethical manner.

The piping device of the present invention can also be applied to underwater concrete systems 1 to 2, and even in that case, the same effects as described above can be achieved.

As explained in revision 1 above, according to the concrete 1 to pouring piping device according to this defense, F?
Concrete 1 to FJ construction U, which has a large difference, effectively suppresses the falling speed of Concrete 1. The mixing effect is increased by 11 degrees, and separation of the constituent interest of the concrete can be prevented.
