(Prior art) It is known that when constructing a building, concrete placed in a formwork is compacted by applying vibrations using a vibrator. For example, a sensor and a vibrator that detects the filling of concrete are attached to the formwork, and the vibrator is activated when the sensor detects the presence of concrete for a specified period of time. However, this may be used to compact the concrete.

(Problems to be Solved by the Invention) However, in the above method, the sensor that detects the filling of concrete utilizes the fact that the poured concrete exhibits conductivity due to the large amount of water contained in it.
In other words, since the sensing part, in which two electrodes are arranged in parallel with a slight distance, is passed through the formwork and a voltage is applied between both electrodes, a through hole for mounting the sensing part is prepared in advance. It was necessary to install the sensor in the formwork, and mounting the sensor was time-consuming and troublesome.

In addition, since the image electrodes of the sensing part are only slightly separated, there is a risk of malfunction as they become energized by adhesion of water spray, etc., and maintain the energized state. There was also an inconvenience that a recessed portion remained, impairing the appearance.

This invention was made in view of the above-mentioned background, and is easy to handle, has excellent operability, can accurately detect the filling of concrete, can be expected to perform a reliable compaction operation, and can be used to clean the concrete surface. The purpose of the present invention is to provide a compaction method for concrete that can be made smooth and a device for the same.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a concrete compaction method in which concrete placed in a form is vibrated by a vibrator to compact it. The vibrator is fixed to a horizontal thick pipe that is locked to the end of the separator, and the implanted sensor that forms the electrode is driven into the mold and locked, and the conduction between the separator and the implanted sensor is monitored to ensure continuity. It is characterized in that the vibrator is started when the vibrator continues for a predetermined period of time, and the vibrator is stopped after the predetermined period of time has elapsed.

In addition, the present invention includes a vibrator fixed to a horizontal thick pipe that is fixed to an end of a separator that penetrates the formwork and is electrically conductive to the separator, and an electrode that is formed and driven into the formwork. a driving sensor to be inserted, a continuity monitoring means for monitoring continuity between the separator and the driving sensor, a vibrator is activated when the continuity detection continues for a predetermined period of time after receiving a detection signal from the continuity monitoring device, and a vibrator is activated after a predetermined period of time has elapsed. The apparatus is characterized by comprising a control means for stopping the apparatus.

(Function) According to the construction method described above, a separator that penetrates the formwork is electrically connected to the vibrator fixed to the horizontal thick pipe, and a sensor that is driven into the formwork and forms an electrode. are electrically connected.

That is, installation is completed by simply fixing the vibrator to the horizontal thick pipe and driving the driving sensor into the formwork, making handling extremely easy. At this time, the implanted sensor can be implanted into an appropriate part of the formwork, and the distance between the separator to be electrically connected and the implanted sensor can be arbitrarily set. Also,
Since it is the tip of the placement sensor that penetrates into the formwork, the concrete surface can be made almost smooth.

Further, with the above configuration, the continuity monitoring means monitors the continuity between the separator and the implantation sensor, and the control means that receives the detection signal starts the vibrator when continuity continues for a predetermined time, and after the predetermined time has elapsed. will be stopped.

9 is connected to the continuity monitor section 50, it is electrically connected to the separator 6 via the horizontal thick pipe 7, and the separator 6 functions as a conduction target. Note that the horizontal thick vibrator 7 and the vertical thick vibrator 8 are assembled in a crosswise manner. FIG. 2 is a plan view of the vibrator 3 portion of FIG. 1 as seen from the arrow.

As shown in an enlarged view in FIG. 3, the implanted sensor 4 has a nail-shaped tip 41 protruding from the sensor body 40, and an electrode 42 inserted into the tip 41.
2 is exposed at the tip of the apex 41, and the continuity monitor section 5
Wired to 0. The implant sensor 4 may be constructed of the nail-shaped electrode 42 itself. The sensor main body 40 is strong enough to withstand the driving force of a mallet 9 or the like, and is locked by driving the tip 41 into the formwork 1. Further, a display section 43 such as an LED indicating that the vibrator 3 is in an operating state is disposed at an appropriate location on the sensor body 40 and connected to the control section 51 .

The continuity monitor section 50 applies a voltage between the separator 6 and the electrode 42 to detect the presence or absence of continuity, and a continuity detection signal is sent to the control section 51 .

That is, the continuity monitor section 50 serves as a continuity monitor means for monitoring the continuity between the separator 6 and the implant sensor 4.

2 is driven into the formwork 1 and locked,
Continuity between the separator 6 and the implant sensor 4 is monitored.

Here, if the conduction continues for a predetermined time, the vibrator 3
The vibrator 3 is started, and the vibrator 3 is stopped after a predetermined period of time has elapsed.

In other words, when the concrete 2 is actually poured, the conduction continues, so filling of the concrete 2 can be accurately detected by continuing the conduction for a predetermined period of time, and at this time, the vibrator 3 is activated.
Since the machine stops after a predetermined period of time has elapsed, it is possible to carry out the compaction operation after a reliable compaction operation. Moreover, all such operations can be automated.

Further, since the driving sensor 4 has a simple structure as described above, it can be miniaturized and the ease of handling can be improved.

Since it is the tip of the placement sensor that penetrates the formwork, the concrete surface can be made smooth.

On the other hand, since continuity continues when concrete is actually placed, it is possible to accurately detect the filling of concrete if continuity continues for a predetermined period of time.At this time, the vibrator is started and stopped after a predetermined period of time. Therefore, reliable compaction operation can be achieved.
