Description

[Detailed Description of the Invention] Conventionally, when concrete is poured into a long part in the vertical direction such as a wall, when the height is high, vibrators and ramming rods cannot reach it, so concrete is spread to every corner within the formwork. It takes effort to do so.

Also, if there is a window, it is difficult for concrete to reach the area under the window.

Furthermore, the worker must use the vibrator or the push rod while moving in the horizontally long portions, which requires a great deal of effort.

The present application was invented in view of these drawbacks, and its purpose is to improve the fluidization of concrete by applying vibrations from outside the formwork to the part filled with concrete, and to improve the fluidity of concrete within the formwork. To provide a vibration compaction method for concrete that can spread concrete to every corner of the concrete and prevent the formation of slabs.

Another object of the present application is to detect vibration waves and automatically move a vibrator to the place where concrete is filled to ensure vibrations are transmitted to the concrete in the formwork. To provide a compaction method.

Another object of the present application is to provide a method for vibratory compaction of concrete, which can be vibrated again after a while after filling the concrete, thereby improving the strength of the concrete. .

Still another object of the present application is to provide a method for vibratory compaction of concrete in which compaction can be performed simply and easily by moving a vibrator to a required location by remote control.

Now, to explain an embodiment to achieve the above purpose, a self-propelled vibrator having a vibration wave detection sensor is movably mounted on the outside of the concrete formwork in the part filled with concrete, and vibrates from the outside of the formwork. A concrete product characterized by moving a vibrator to a place filled with concrete and transmitting vibration to the formwork to improve the fluidization of the concrete and spread the concrete to every corner within the formwork. This relates to a vibration compaction method.

To explain the details, formwork 1 is double-assembled inside and outside.
Attach the moving rail 2 to the outside of the machine in the vertical direction, horizontal direction, or both vertical and horizontal directions (see Figures 1 and 2),
After the self-propelled vibrator 3 is movably attached to the moving rail 2 and concrete 4 is poured into the formwork 1, the self-propelled vibrator 3 is vibrated while traveling, and the portion filled with concrete 4 is By applying vibration from the outside of the formwork 1, the concrete 4
This makes it possible to improve the fluidization of the concrete 4 and spread the concrete 4 to every corner within the formwork 1.

In the case of Fig. 3, scaffolding 5 is erected outside the formwork 1,
A bracket 6 is attached to the scaffold 5 between the scaffold 5 and the formwork 1.
, the rail 2 is attached to the bracket 6, and the self-propelled robot 9 with the vibrator 8 attached to the tip of the arm 7 is placed movably on the rail 2, and the vibrator 8 is brought into contact with the formwork 1. The self-propelled robot 9 is controlled from another location, vibrates the vibrator 8 while moving the self-propelled robot 9, and applies vibration from the outside of the formwork 1 to the part filled with concrete 4. This makes it possible to improve the fluidization of the concrete 4 and spread the concrete 4 to every corner within the formwork 1.

In the case of FIG. 4, after the formwork 1 is removed from the lower wall 10 which has already solidified and curing has been completed, a bracket 6 is attached to the wall 10 as appropriate, and a rail 2 is installed on the upper part of the bracket 6. , rail 2
A self-propelled robot 9 with a vibrator 8 attached to the tip of the arm 7 is movably placed on top, and the vibrator 8 is brought into contact with the formwork 1 assembled on the top, and the self-propelled robot 9 is moved from another location. The vibrator 8 is vibrated while the self-propelled robot 9 is controlled to apply vibration from outside the formwork 1 to the part filled with the concrete 4, thereby improving the fluidization of the concrete 4. It is possible to spread the concrete 4 to every corner within the formwork 1.

In the case of FIGS. 3 and 4, the self-propelled robot 9 is shown to be moved on the rail 2, but the self-propelled vibrator is directly mounted on the rail without using the self-propelled robot 9. It is also possible to transmit vibrations to the concrete while moving through automatic placement control.

Furthermore, the most distinctive feature of this application is that a vibration wave detection sensor 11 is attached to the vibrator, and by catching changes in the vibration waves of the vibrator 8, it is possible to automatically detect areas filled with concrete and areas not filled with concrete. The vibration wave detection sensor 11 is detected and transmitted to the control device, so that the vibrator is promptly moved to the place filled with concrete, and the vibration is transmitted to the formwork filled with concrete. By attaching it to the vibrator 8, it is possible to reliably transmit vibrations to the area filled with concrete.

Therefore, it is possible to prevent unnecessary vibrations from being transmitted to the formwork 1 which is not filled with concrete 4, so that vibration noise is not generated.

As mentioned above, the present invention is to install a self-propelled vibrator equipped with a vibration wave detection sensor on the outside of a concrete formwork in a movable manner, apply vibrations from outside the formwork, and catch changes in the vibration waves of the vibrator to make concrete. Automatically detects where the gas is filled and where it is not, and communicates this to the control device.
It is characterized by moving the vibrator to the place filled with concrete and transmitting vibration to the formwork filled with concrete, improving the fluidization of the concrete and spreading the concrete to every corner inside the formwork. Therefore, it has the following effects.

a Vibration wave detection sensor detects areas where concrete is not filled, the vibrator is quickly moved to the area where concrete is filled, and concrete is filled by transmitting vibration to the formwork filled with concrete. vibration can be reliably transmitted to the location where it is being
Since vibrations are not needlessly transmitted to formworks that are not filled with concrete, the generation of vibration noise can be reduced accordingly.

b. Concrete spreads to every corner of the formwork, making it difficult to form slabs.

c. After filling the concrete, it can be re-vibrated for a while, which can improve the strength of the concrete.
