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 it is necessary to spread the concrete evenly into the formwork. It takes a lot of effort.

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

Furthermore, in the long portion of the transverse rotation, the operator must use the vibrator flat rod while moving, 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 to the part filled with concrete from outside the formwork. To provide a method for vibratory compaction of concrete, which can spread the concrete evenly and prevent the formation of slabs.

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. .

Yet another object of the present application is to provide a method for vibratory compaction of concrete that requires fewer craftsmen to cast concrete.

Still another object of the present application is to provide a method for compacting concrete by simply and easily by moving a vibrator to a required location by remote control.

Now, to explain the example in order to achieve the goal of 1 above, a self-propelled vibrator can be moved freely to the outside of the concrete formwork in the area where concrete is filled. This relates to a method of shaking and compacting concrete, which is characterized by improving the fluidization of concrete and spreading the concrete to every corner within the formwork.

The details are as follows: The moving rail (2) is dammed vertically, horizontally, or both vertically and horizontally on the outside of the formwork (1), which is double-assembled (see Figures 1 and 2). ), the self-propelled vibrator (3) is movably mounted on the moving rail (2), and the self-propelled vibrator (3) is moved after pouring concrete (4) in the formwork (1). By applying vibration to the part filled with concrete (4) from outside the formwork (1), the fluidization of the concrete (4) is improved and the corners inside the formwork (1) are Concrete (4)
) can be widely distributed.

In the case of Figure 3, scaffolding (5) is erected outside the formwork (1),
Install the scaffold (5) K bracket (6) between the scaffold (5) and the formwork (11), and place the rail (2) on the bracket (6).
) is installed by movably mounting a self-propelled robot (9) with a vibrator (8) attached to the tip of the arm (7) on the rail (2), and attaching the vibrator (8) to the formwork (1). ), vibrate the vibrator (8) while moving the self-propelled robot (9) under control of the self-propelled robot (9) from another location,
Concrete +) -) (By applying vibration from the outside of the formwork (1) to the part where 41 is filled, the concrete (4) is fluidized well and spread to every corner inside the formwork (1). It is possible to spread the concrete (4) up to the surface.

In the case of Fig. 4, after removing the formwork (1) from the lower wall (00) which has already solidified and completed curing, etc., attach the bracket (6) to the wall (11) as appropriate. ), a self-propelled robot (9) with a vibrator (8) attached to the tip of the arm (force) is movably mounted on the rail (2), and the vibrator ( 8
) is brought into contact with the formwork (1) assembled on the top, and the self-propelled robot (9) is controlled from another location to form the self-propelled robot (
By vibrating the vibrator (8) while moving the concrete (9) and applying vibration from outside the formwork (1) to the part filled with the concrete (4), it is possible to better simulate the fluidization of the concrete (4). , it is possible to spread the concrete (4) to every corner within the formwork (11).

In the case of Figures 3 and 4, the self-propelled robot (9
) is shown to be moved on a rail (2), but instead of using a self-propelled robot (9), a self-propelled vibrator is placed directly on the rail and the vibration is transferred to the concrete while moving under automatic control. It is also possible to convey the information in the following manner, without departing from the gist of the present application.

Furthermore, in the present application, a vibration wave detection sensor Ql) is attached to the vibrator, and by catching changes in the vibration waves of the vibrator, it automatically detects areas filled with concrete and areas that are not filled with concrete. The vibration wave detection sensor (11) is transmitted to the control device, so that the vibrator is quickly moved to the place where concrete is filled, and the vibration is transmitted to the formwork filled with concrete. 8), it is possible to reliably transmit vibrations to the area filled with concrete.

Therefore, the formwork (1) is not filled with concrete (4).
), it is possible to prevent unnecessary transmission of the photographing action, and therefore vibration noise is not generated.

The present application is characterized in that a self-propelled vibrator is movably attached to the outside of the concrete formwork in areas filled with concrete such as Jakujo, and the concrete is distributed by applying vibrations from outside the formwork. Therefore, it has the following effects.

a. Concrete will spread to every corner of the formwork, making it difficult to form slabs.

b. After filling the concrete, it can be vibrated again after a while, so the strength of the concrete can be measured.

C. The number of craftsmen involved in pouring concrete can be reduced.
