DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete placing apparatus according to an embodiment of the present invention will be described in more detail below with reference to the drawings.

Referring to FIG. 1, in FIG. 1, 1 is a concrete mixer, and 2 is an agitator which is supplied with concrete from the concrete mixer 1 and temporarily stores concrete while rotating gently. Reference numeral 3 is a concrete press-fitting means composed of a screw extruder to which concrete is naturally dropped from the agitator 2 and supplied, and reference numeral 4 is a squeeze type concrete pump for press-fitting the concrete from the concrete press-fitting means 3 and pumping it. It is a pumping means. Reference numeral 5 is a concrete pumping pipe communicating with the outlet of the concrete pumping means 4. Reference numeral 6 denotes a concrete pressure feeding means control device for controlling the start / stop of the agitator 2, the concrete pressure feeding means 3 and the concrete pressure feeding means 4 and the discharge amount. Reference numeral 7 is a remote terminal capable of performing remote operation / remote alarm by communicating data with the concrete pumping means control device 6 by a wireless communication system.
The remote terminal 7 is provided with a concrete pressure feeding means control switch 71 for controlling the concrete pressure feeding means 3 and the concrete pressure feeding means 4, and an alarm means 72 for sounding when the amount of concrete in the agitator 2 decreases below a certain amount. There is. Further, the remote terminal 7 is provided in the vicinity of the tip of the concrete pumping pipe 5, and can be operated by a worker.

A worker who holds the tip of the concrete pressure-feeding pipe 5 can place concrete with the tip of the concrete pressure-feeding pipe 5 facing the slope of the slope while operating the concrete pressure-feeding means control switch 71. When the pouring of concrete for one law frame is completed, the concrete pressure feeding means control switch 71 is operated to temporarily stop the concrete pressure feeding means 3 and the concrete pressure feeding means 4, move to the next law frame, and immediately feed the concrete pressure. By operating the means control switch 71 to activate the concrete press-fitting means 3 and the concrete press-feeding means 4, the concrete placing work can be executed again. Further, the alarm means 72 beeps to inform the worker that the concrete in the agitator 2 has become insufficient. In this way, one worker who holds the tip of the concrete pumping pipe 5 can control the instruction of concrete placing and the operation of placing the concrete, so that not only the work efficiency can be improved , but also the concrete should not be used.
Even if concrete stagnation occurs in the pressure pipe,
A worker holding the tip of the crepe pressure feed pipe 5 immediately
You can stop the pumping of concrete when you find
Nucleate is consolidated and dehydrated in a concrete pressure pipe.
Preventing hardening in concrete pressure pipes
I can .

In this embodiment, a squeeze pump is used as the concrete pumping means 4, but a spraying machine, a penetrating cylinder type pump, a piston pump or the like can also be used.
When the spraying machine is used, the mixer 1 and the agitator 2 are generally not used because the spraying machine is kneaded in the tank of the spraying machine without being kneaded by the mixer.

Further, the concrete press-fitting means 3 is not essential.

Further, in the present embodiment, the remote terminal 7 communicates with the control device 6 by the wireless communication system, but the data communication by the wired communication system is also possible.

The concrete mixer 1, the agitator 2 and the concrete press-fitting means 3 are three-dimensionally constructed as shown in the figure. Further, the concrete press-fitting means 4 is constructed integrally with the concrete press-fitting means 3. Further, on the upper part of the concrete mixer 1, a feeder with a scale for sand and gravel, a feeder with a scale for cement, and a feeder with a scale for water, which are not shown, are provided. With such a configuration, a large installation area for installing the concrete placing device is not required, and further, the concrete placing device can be easily moved as the construction progresses.

When the amount of concrete in the agitator 2 decreases below a certain amount, the control device 6 sends an alarm signal to the remote terminal 7 and a cement supply command signal to the concrete mixer 1 as described above. In response to this signal, a control device (not shown) provided in the concrete mixer 1 opens a gate provided at the bottom of the concrete mixer 1 to supply concrete to the agitator 2 and, if necessary, to show the figure. Not sand
It is also possible to automatically drive the gravel meter-equipped feeder, the cement meter-equipped feeder and the water meter-equipped feeder to replenish the concrete in the concrete mixer 1.

In the concrete pouring apparatus according to the present embodiment, depending on the case, the above-mentioned worker at the pouring site, a feeder with a scale for sand and gravel, a feeder with a scale for cement, and water. It is possible for two people, one who manages a feeder with a measuring instrument and another who also manages replenishment and management of sand and gravel, water, and cement, to cast concrete.

[0016]

As described above, the long distance according to the present invention
In concrete pouring equipment used for sloped concrete pouring with high lift and low head, a concrete pumping means control switch for controlling concrete pumping means is provided near the tip of the concrete pumping pipe. Moreover, since there is an alarm means that sounds when the amount of concrete stored in the agitator falls below a certain amount,
Fool the worker gripping the leading end of the concrete pumping tube will be in charge of instruction concreting, possible to reduce the worker, it is possible to improve the work efficiency of concreting
In the unlikely event that the concrete is
Even if stagnation of the reit occurs, the tip of the concrete pumping pipe
The operator holding the slab immediately discovered this and
You can stop the feeding, the concrete is concrete
It is compacted and dehydrated in the pressure pipe and hardened in the concrete pressure pipe.
It is possible to prevent it from becoming solid and to perform subsequent processing such as cleaning.
It doesn't require much time and effort.
