[Action]

 According to the pouring device in the floor concrete construction of the present application, concrete is pressure-fed into the case by the pressure-feeding means and temporarily stored. The stored concrete falls by gravity toward the bottom of the case and is discharged from the opening to the floor surface for casting. Then, by moving the case in a substantially horizontal plane by the moving means, concrete is sequentially placed on the floor surface. Here, since the leveling plate is connected to the opening of the case in a substantially horizontal manner, when the case is moved by the moving means, the leveling plate flattens the level of the concrete surface. That is, it is possible to perform the concrete placing work and the leveling work at the same time, which reduces the labor.

According to the placing device in the floor concrete construction according to claim 2 of the present application, since the leveling plate is held within the reference plane by the holding means, the case is moved by the moving means. Then, the leveling plate moves in the reference plane, and the floor surface flattened by the leveling plate is located in the reference plane, which improves the finishing accuracy of the floor surface.

According to the placing device in the floor concrete construction according to claim 3 of the present application, the leveling plate is vibrated by the vibrating means, and the surface of the concrete is hit by the vibrating leveling plate. Therefore, the so-called flaring work for hitting the concrete surface can be performed concurrently with the placing work and the leveling work, which reduces the labor.

 Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention.

The driving apparatus 1 of the present embodiment is attached to the arm mechanism 2 of the traveling main body portion including the arm mechanism 2 and a turning mechanism (not shown). This traveling main body can be moved on the floor surface by a traveling mechanism such as a caterpillar, and the placing device 1 can be moved in a horizontal plane by traveling by the traveling mechanism and turning by the turning mechanism. ing. The traveling mechanism and the turning mechanism constitute the moving means of the present invention.

A pump car (not shown) for pumping concrete is attached to the traveling main body. The pipe from the pump car is connected to the concrete supply port provided in the traveling body. The piping on the pump car side is rotatably connected to the concrete supply port, and can follow the movement of the traveling main body without changing the piping for traveling of the traveling main body. The pump car and the piping constitute the pumping means of the present invention.

As shown in FIG. 1, the casting apparatus 1 of this embodiment is provided with a case 3 at the top of which a pipe for supplying concrete is connected. The case 3 has a flat box shape, and an opening 4 is formed in the lower portion of the case 3 as shown in FIG. A plurality of baffle plates 5 are attached to the inner wall of the case 3 along the longitudinal direction of the case 3 and with gaps between the baffle plates 5. As shown in FIG. 2, leveling plates 6 and 7 extending in a substantially horizontal direction are attached to the outside of the opening of the case 3. A vibrator 8 is attached to one of the leveling plates 7. The vibrator 8 constitutes the vibrating means of the present invention.

As shown in FIG. 1, the case 3 is mounted on a frame 9, and a mounting portion 10 is formed on the frame 9. The mounting portion 10 is screwed onto a ball screw 11 to separate the frame 9 from the frame 9. We support in possession. The ball screw 11 is rotatably supported by a frame 12 connected to the arm mechanism 2 of the traveling main body. A motor 13 is fixed above the frame 12 in the figure, and a rotation shaft of the motor 13 is connected to an upper end of the ball screw 11 in the figure.

As shown in FIG. 1, a laser level sensor 14 is attached to the frame 12, and the laser level sensor 14 detects the height position of the leveling plates 6 and 7 of the case 3. Is becoming The output end of the laser level sensor 14 is connected to a control means (not shown), and the output end of this control means is connected to the motor 13. Here, the control means compares the heights of the leveling plates 6 and 7 of the case 3 detected by the laser level sensor 14 with the height of the reference surface, and outputs a drive signal corresponding to the difference between them to the motor 13 I am trying to output to.

The frame 9, the mounting portion 10, the ball screw 11, the frame 12, the motor 13 and the laser level sensor 14 constitute the holding means of the present invention.

Next, the operation of this embodiment will be described.

First, concrete is supplied from the top of the case 3 to the inside of the case 3. Since the baffle plates 5 are attached to the inner wall of the case 3 with a gap between each other, the supplied concrete flows along the baffle plates 5, and the gaps between the baffle plates 5 make the case 3 downward. And is evenly dispersed in the case 3 and temporarily stored.

Then, the stored concrete flows out from an opening 4 provided below the case 3 and is poured onto the floor surface. The traveling mechanism and the turning mechanism provided in the traveling main body are driven to horizontally move the case 3 substantially at right angles to the longitudinal direction thereof.

Then, the surface of the concrete cast by the leveling plates 6 and 7 connected to the opening 4 of the case 3 in a substantially horizontal direction is leveled to form a flat floor surface. In addition, the case 3 is horizontally moved at a speed commensurate with the driving amount corresponding to the thickness of the slab. By moving the case 3 horizontally, the concrete placing work and the leveling work can be performed automatically at the same time, so that the labor can be greatly reduced. In addition, since there is no need for the conventional landslide work for breaking the concrete piles after placing concrete, it is possible to shorten the working time and simplify the work.

Further, by driving the vibrator 8 provided on the leveling plate 7, the surface of the cast concrete is struck to sink the aggregate or to carry out so-called amending work for exposing the mortar component to the surface. You can

Here, when the height of the case 3 changes, if the state is left as it is, the leveling plates 6 and 7 provided on the case 3 are displaced in the height direction from the set reference plane. The surface of the cast concrete is leveled by the leveling plates 6 and 7, and the finishing accuracy of the floor surface is lowered.

However, in the present embodiment, the height positions of the leveling plates 6 and 7 of the case 3 are detected by the laser level sensor 14 and output to the control means, and the control means is the leveling plate 6 of the case 3. A driving signal is issued to the motor 13 so that the numbers 7 and 7 are within the reference plane. That is, the drive signal causes the motor 13 to rotate a predetermined amount and the ball screw 11 to rotate, so that the frame 9 supported by the ball screw 11 via the mounting portion 10 is vertically moved up and down, and the height of the case 3 is increased. It is controlled to have a predetermined value. Therefore, when the height position of the case 3 changes, the case 3 is quickly moved up and down so that the height positions of the leveling plates 6 and 7 do not change with respect to the reference plane. It is possible to improve the finishing accuracy of the floor surface. Therefore, skilled workers are not required for leveling work, and human resources can be effectively used.

In this embodiment, the leveling plates 6 and 7 are attached so as to project outward from the edge of the opening 4 of the case 3, but slightly extend inward from the edge of the opening 4. It may be attached in a state.

Next, FIGS. 3 to 6 show another embodiment of the present invention. The same components as those in the above-mentioned embodiment are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 3, a case 16 is provided in the placement device 15 of this embodiment. The case 16 has a flat box shape, and an opening 17 is formed in the lower portion of the case 16 as shown in FIG. A casting pipe 18 penetrates the case 16 through one side wall along the longitudinal direction of the case 16 and is attached to the inner wall of the case 16 with a gap. A pipe for supplying concrete is connected to the projecting end of the casting pipe 18. Further, as shown in FIG. 6, the casting pipe 18 has one end sealed by a stopper plate 20 and an opening 19 notched upward. The opening 19 has a larger opening width on the leading end side (stop plate 20 side) than on the base end side (side away from the stop plate 20). This is because when concrete is supplied to the driving pipe 18, the pressure is large on the base end side and small on the stop plate 20 side, and if the opening width is kept constant in the longitudinal direction, it overflows from the opening 19. This is to make the amount of concrete that overflows from the opening 19 uniform in the longitudinal direction of the case 16 because the amount of concrete to be used differs in the longitudinal direction of the casting pipe 18.

Next, the operation of this embodiment will be described.

First, concrete is supplied into the interior of the casting pipe 18 from the projecting end of the casting pipe 18. The supplied concrete overflows laterally from the opening 19 of the casting pipe 18 as shown by an arrow in FIGS. 4 and 5, and from the gap formed between the casting pipe 18 and the inner wall of the case 16 to the case 16. Flows downwardly, is evenly dispersed in the case 16, and is temporarily stored.

Then, the stored concrete flows out from an opening 17 provided below the case 16 and is poured onto the floor surface. The case 16 is horizontally moved at a substantially right angle to the longitudinal direction of the case 16 by driving the traveling mechanism and the turning mechanism provided in the traveling main body.

Then, the surface of the concrete cast by the leveling plates 6 and 7 connected to the opening 17 of the case 16 in a substantially horizontal direction is leveled. Also in this embodiment, as in the above-described embodiments, by horizontally moving the case 16, the concrete placing work and the leveling work can be performed simultaneously and automatically. The labor can be greatly reduced. In addition, since there is no need for the conventional landslide work for crushing concrete piles after placing concrete, it is possible to shorten the work time and simplify the work.

Further, by driving the vibrator 8 provided on the leveling plate 7, the surface of the cast concrete is hit to sink the aggregate or to perform the so-called amending operation of exposing the mortar component to the surface. You can

Also in this embodiment, the heights of the leveling plates 6 and 7 of the case 16 are detected by the laser level sensor 14 so that the leveling plates 6 and 7 of the case 16 are positioned on the reference plane. A drive signal is issued to 13. Then, the drive signal causes the motor 13 to rotate a certain amount, the ball screw 11 is rotated, and the frame 9 supported by the ball screw 11 via the mounting portion 10 is vertically moved up and down to raise the height of the case 16. By controlling, the height positions of the leveling plates 6 and 7 are controlled. Therefore, since the leveling plates 6 and 7 are moved in the horizontal direction with the leveling plates 6 and 7 positioned on the reference plane, the finishing accuracy of the floor surface can be improved.

Next, FIGS. 7 to 9 show still another embodiment of the present invention. The same components as those in the above embodiment are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 7, the placing device 21 of the present embodiment is provided with a case 22 at the top of which a pipe for supplying concrete is connected. The case 22 has a flat box shape, and an opening 23 is formed in the lower portion of the case 22 as shown in FIG. As shown in FIGS. 8 and 9, a screw auger 24 is rotatably attached to the lower outer surface of the case 22. A leveling plate 7 is connected to the screw auger 24, and a vibrator 8 is mounted on the leveling plate 7.

Next, the operation of this embodiment will be described.

First, concrete is supplied into the case 22 from the top of the case 22. The supplied concrete is temporarily stored in the case 22 and poured into the floor through the opening 23. Here, when the screw auger 24 is rotated, the concrete that has been placed is scraped out by the screw auger 24, and the concrete is uniformly dispersed in the longitudinal direction of the case 22 by the rotation of the screw auger 24 and roughened. It

Then, the traveling mechanism and the turning mechanism provided in the traveling main body are driven to horizontally move the case 22 substantially at right angles to the longitudinal direction thereof. Then, the surface of the concrete placed by the leveling plates 6 and 7 connected to the opening 23 of the case 22 in a substantially horizontal direction is leveled. Also in this embodiment, as in the above-described embodiments, by horizontally moving the case 22, the concrete placing work and the leveling work can be performed simultaneously and automatically. The labor can be greatly reduced. In addition, since there is no need for the conventional landslide work that breaks down the piles of concrete after placing concrete, it is possible to shorten the work time and simplify the work.

By driving the vibrator 8 provided on the leveling plate 7, the surface of the cast concrete is struck to sink the aggregate or so-called amending work for exposing the mortar component to the surface. You can

Also in this embodiment, the heights of the leveling plates 6 and 7 of the case 22 are detected by the laser level sensor 14 so that the leveling plates 6 and 7 of the case 22 are positioned within the reference plane. A drive signal is issued to the motor 13. The drive signal causes the motor 13 to rotate by a predetermined amount and the ball screw 11 to rotate, so that the frame 9 supported by the ball screw 11 via the mounting portion 10 is vertically moved up and down to raise the height of the case 22. By controlling, the height positions of the leveling plates 6 and 7 are controlled. Therefore, since the leveling plates 6 and 7 are moved in the horizontal direction with the leveling plates 6 and 7 positioned on the reference plane, the finishing accuracy of the floor surface can be improved. Therefore, skilled workers are not required for leveling work, and human resources can be effectively used.

10 and 11 show another embodiment of the present invention.

Similar to the above-described embodiment, the driving apparatus 30 of this embodiment has a case 32 having an opening 31 provided below and extending in the horizontal direction, and a leveling plate connected to the opening 31 substantially horizontally. 3 3 and. A laser receiver 34 for detecting the height of the case 32 is attached to the end of the case 32.

The case 32 is connected to the upper swing body 37 via a level adjusting mechanism 40 for adjusting the level thereof. The level adjusting mechanism 40 controls the height of the case 32 in the vertical direction so that the leveling plate 33 is located on the reference plane based on the height detected by the laser receiver 34. Is. The laser receiver 34 and the level adjusting mechanism 40 form the holding means of the present invention.

The upper revolving structure 37 is rotatably mounted on a carriage 36 having a caterpillar 35. A hopper 38 for storing concrete is attached to the upper swing body 37, and the hopper 38 is connected through a pipe 39 to a pump car (not shown) that pumps the concrete under pressure. The pipe 39 has a bendable structure, and can be displaced following the traveling of the carriage 36 and the swing of the upper swing body 37. Further, the lower portion of the hopper 38 and the case 32 are connected via a pipe 41. The pump car, the hopper 38, the pipe 39, and the pipe 41 constitute the pumping means of the present invention, and the upper swing body 37, the caterpillar 35, and the carriage 36 constitute the moving means of the present invention.

The reinforcing bars in the path on which the caterpillar 35 of the carriage 36 travels are previously reinforced with spacers or the like so that the reinforcing bars do not bend or deform due to the traveling of the carriage 36.

Next, the operating state of this embodiment will be described.

First, concrete is pumped from the pump car into the hopper 38 via the pipe 39, and a certain amount of concrete is temporarily stored in the hopper 38. The stored concrete is supplied into the case 32 at a predetermined supply amount through the pipe 41. The concrete supplied into the case 32 is temporarily stored in the case 32, flows out from the opening 31 provided in the lower part of the case 32, and is poured onto the floor surface.

Here, when the caterpillar 35 is driven to move the carriage 36 to the right side in the drawing of FIG. 10, the surface of the cast concrete is connected by the leveling plate 33 which is connected to the case 32 substantially horizontally. A leveled and flat floor is formed. Thus, the concrete placing work and the leveling work can be simultaneously and automatically performed, and the labor can be reduced. In addition, since there is no need for the conventional landslide work for breaking the concrete piles after placing concrete, it is possible to shorten the working time and simplify the work.

Further, in this embodiment, the laser receiver 34 is provided to detect the height of the case 32, and the level adjusting mechanism 40 is driven to control so that the leveling plate 33 of the case 32 is located on the reference plane. Therefore, it is possible to prevent the leveling of the case 32 from being displaced from the reference plane due to the height variation of the case 32 during the placing work and the leveling work by the placing device 30, and thus the finishing accuracy of the floor surface can be improved. Can be kept high. Therefore, skilled workers are not required for leveling work, and human resources can be effectively used.

FIG. 12 shows still another embodiment of the present invention.

The placing apparatus 50 of the present embodiment is provided with a case 52 to which concrete is supplied from the upper part in the drawing through a pipe 51, similarly to the above-mentioned embodiments, and an opening is provided below the case 52. Are formed. A leveling plate 61 is connected to the opening. A laser receiver 53 for detecting the height of the case 52 is attached to the case 52. The case 52 is connected to a slide mechanism 55 via a level adjusting mechanism 54 that adjusts the height of the case 52. The slide mechanism 55 has a function of moving the case 52 in the left-right direction in the drawing. The laser receiver 53 and the level adjusting mechanism 54 form the holding means of the present invention.

Further, two caterpillars 56 made of rubber crawlers are placed on the floor surface in which the reinforcing bars are assembled, and a frame 57 extending in the horizontal direction is mounted on the caterpillars 56 in a bridged state. Has been. When the caterpillar 56 is driven, the frame 57 moves in the front-rear direction in the figure. A rail 58 is attached along the longitudinal direction of the frame 56, and the slide mechanism 55 is attached to the rail 58 so as to be movable in the longitudinal direction of the rail 58. The slide mechanism 55, the caterpillar 56, the frame 57, and the rail 58 constitute the moving means of the present invention.

A pipe moving device 59 connected to a pump car (not shown) is attached to the rear end of the pipe 51, and is moved in the front-rear direction in the drawing as the case 52 is moved. The pipe moving device 59 and the pipe 51 are connected via a bendable pipe 60. Here, instead of the pipe 60, a conveyor type pipe may be used. The pump car, the pipe 51, the pipe moving device 59, and the pipe 60 constitute the pressure feeding means of the present invention.

Further, the reinforcing bars in the moving path of the caterpillar 56 (the hatched area in the figure) are preliminarily reinforced with a spacer or the like so that the reinforcing bars will not be bent or deformed by the traveling of the caterpillar 56. There is.

Next, the operation of this embodiment will be described.

First, concrete is supplied into the case 52 through the pipe moving device 59, the pipe 60, and the pipe 51. The concrete supplied into the case 52 is temporarily stored in the case 52, flows out from an opening provided in the lower part of the case 52, and is poured onto the floor surface.

When the slide mechanism 55 is made to traverse along the rail 58 from the right side in the figure to traverse the case 52, a concrete plate cast by the leveling plate 61 connected to the opening of the case 52 is placed. The surface is leveled to form a flat floor surface. The traverse speed of the case 52 is changed in accordance with the change in the amount of concrete to be placed, so that the concrete can be uniformly placed on the floor surface. Thus, by traversing the case 52, the concrete placing work and the leveling work can be simultaneously and automatically performed, and the labor can be reduced. In addition, since it is not necessary to perform the conventional landslide work that destroys the piles of concrete after placing concrete, it is possible to shorten the work time and simplify the work.

Further, the traverse of the case 52 is performed while the drive of the caterpillar 56 is stopped. That is, while the caterpillar 56 is driven and the frame 56 is moved, the placing work and the leveling work are not performed. This is because the concrete is placed on the part along the frame 56, and then the frame 56 is moved to place the concrete sequentially on the connecting part to finish the flat floor surface one by one.

Further, at a portion where the frame 56 cannot enter, such as on the beam, the case 52 is moved in the left-right direction in the drawing by the slide mechanism 55 so that the case 52 enters the beam, and the placement work is performed. I try to do leveling work.

Also in this embodiment, similarly to the above-described embodiments, the laser receiver 53 is provided to detect the height of the case 52, and the level adjusting mechanism 54 is driven based on the detection result to connect to the case 52. Since the leveling plate 61 is controlled so as to be located on the reference plane, the height of the case 52 is changed and the leveling plate 61 is moved during the setting work and the leveling work by the setting device 50. It is possible to prevent deviation from the reference surface and maintain high finishing accuracy of the floor surface. Therefore, skilled skilled workers are not required for leveling work, and effective use of human resources can be achieved.
