Description

[Detailed Description of the Invention] Conventionally, it has been known to compact the ready-mixed concrete by applying vibration to it when constructing a structure. In order to know if there is a vibrator, you can visually check it from the opening at the top of the formwork and drive the vibrator.However, when the structure is large, just checking visually can be a difficult task, and it is necessary to check the power source that drives the vibrator. Not only did the workers have to be contacted by transceiver, etc., but the lower part of the window frame could not be seen at all, so the vibrator was driven entirely by intuition based on the state of the surrounding ready-mixed concrete. However, these methods often had the disadvantage of subjecting the fresh concrete to vibrations before it was poured.

The present application relates to an automatic compaction method for concrete at τ-5, which ensures vibration is applied after the fresh concrete is poured without imparting vibration to the unplaced areas as described above.

The present invention also takes advantage of the fact that the formwork slightly bulges outward when pouring fresh concrete, and installs a microswitch very close to the outside of the formwork, and the microswitch is activated by the bulge of the formwork. This invention relates to an automatic compaction method for busy concrete that automatically drives a vibrator.

Now, to explain the example, a micro switch (4) is set at one point in the circuit of a vibrator (3) connected to a power source between a formwork (1) and a batapipe (2), and a micro The vibrator (3) is attached to the outside of the formwork (1) near the location where the switch (4) is set.

According to the above structure, the present application has raw concrete in the formwork (1).
-1-(5) When pouring, the poured ready-mixed concrete (
5) causes the formwork (1) to slightly bulge outward (6), and this bulge closes the contact (4a) of the microswitch (4), thus closing the circuit of the vibrator (3). By driving the vibrator (3) to vibrate the formwork (1), the fresh concrete (5) in the formwork (1) is vibrated and compacted.

In order to vibrate for a certain period of time and then stop the vibrating IJJ machine (3), install a manual open/close switch in a part of the circuit of the vibrator (3), and open and close the circuit while measuring the time. Although it is a good device, in order to visually check which vibrator (3) is vibrating, it is necessary to install an indicator lamp in a part of the circuit of the vibrator (3) so that it lights up when the micro switch (4) is closed. Then the vibrator (3) that is being driven is -
It is something that can be seen with the naked eye.

A suitable number of vibrators (3) are provided in the formwork (1).

In this application, as described above, a microswitch is set at one point in the circuit of a vibrator connected to a power source between the formwork and the butterpipe, and the vibrator is placed outside the formwork near the point where the microswitch is installed. When attached to the mold, the mold expands slightly outwards due to the fresh concrete poured in the formwork, which closes the micro switch and drives the vibrator to vibrate the fresh concrete. When the concrete is poured, the formwork expands due to the pressure of the fresh concrete and the vibrator is automatically driven, so there is no need to measure whether the fresh concrete has been poured, and the fresh concrete can be compacted reliably. It is.

Claims (1)

[Claims] (1) Set a microswitch installed at one point in the circuit of the vibrator connected to the power source between the formwork and the butterpipe, and attach the vibrator to the outside of the formwork near the point where the microswitch is installed. This automatic concrete compaction method is characterized in that the formwork slightly bulges outward due to the fresh concrete placed in the frame, which closes a microswitch and drives a camera to give vibration to the fresh concrete.
