Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork for manufacturing a concrete building block in which a decorative material such as natural stone is planted on a front surface which is a wall surface.

[0002]

2. Description of the Related Art In a conventional concrete building block in which a concrete ground surface appears on the front surface of the block, only a dry and monotonous wall surface can be obtained. Therefore, a sand layer having a certain thickness is provided at the bottom of the formwork. Arrange decorative materials such as natural stone cutting pieces and split pieces on top, pour concrete into the formwork so as to embed the decorative material, remove excess sand after hardening of the concrete, and put it on the front of the block A method of exposing the decoration material has been proposed.

In this method, since the base of the decorative material is directly planted in the concrete of the block, there is no problem of peeling and dropping of the decorative material, and since natural stone is used as the decorative material, it is natural. It is possible to construct a wall surface that is well suited to the environment. This method is effective in the casting method that uses concrete with a large slump value, but in the immediate demolding method in which concrete with a small slump value is pressed in the formwork, the corners of the formwork and core are Since the corners were not well filled with concrete, it was easy for a product with nests in the shoulder to appear.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to accurately fill concrete, to obtain a dense structure, and to easily remove the product block from the mold by separating the mold. It is an object of the present invention to provide a formwork for manufacturing a decorative material-implanted concrete building block that can be assembled quickly and accurately.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The molding process of a stacking block will be described below with reference to the molding machine shown in the drawings using the manufacturing mold of the present invention. In FIG. 1, the molding machine 11 is in the original position, the mold body 4 is in the normal position with the upper opening 7 facing upward, the moving hopper 8 is in the retracted end position, and the press 9 is in the raised end position. The elevator 12 is at the lower end position.
The operation of the molding machine is started from this state.

In a production line before the molding machine 11, a sand layer 2 having a predetermined thickness is formed in the face plate 1, and a decorative material 3 such as natural stone is placed side by side on the sand layer 2. The face plate 1 conveyed by a face plate pusher (not shown) is placed on the elevator 12. The elevator 12 is guided by the guide rod 14 by the drive of the hydraulic cylinder 13 to rise to the intermediate position, and is stopped by the intermediate limit switch LS-4.

By the elevation of the elevator 12, the face plate 1 is inserted into the cylindrical body 5 of the form body 4 through the lower opening 6 as shown in FIG. 7, and the face plate 1 is located below the normal press-molding position. Come to the filling position. The press molding position of the face plate 1 is shown by a solid line in FIGS. 4 and 5, and the filling position of the face plate 1 is shown by a chain line in FIGS. 4 and 5. The face plate 1 is held at this filling position by stopping the operation of the hydraulic cylinder 13.

Here, the vibrators 1 mounted on the left and right sides of the mold body 4 by driving the electric motors 17 and 18, respectively.
5, 16 are activated, and vibration is applied to the form body 4. Simultaneously with the start of the mold vibration, the moving hopper 8 is moved forward by the driving of the hydraulic cylinder 19, and when the movable hopper 8 reaches the position on the upper surface opening 7 of the mold body 4, the forward end limit switch LS-
Stop at 7.

The moving hopper 8 moves backward for the set time of the timer, and then moves forward again to move the forward end limit switch LS.
Stop at -7. The amount of retreat of the moving hopper 8 is limited to a range in which the front end wall plate 8a of the moving hopper 8 does not return beyond the upper surface opening 7 of the mold 4. After repeating the backward movement and the forward movement a predetermined number of times, the moving hopper 8 is finally stopped by the forward end limit switch LS-7, and the moving hopper 8 moves to the form 4
It is held at a position directly facing the upper surface opening 7.

By driving the electric motor 22, the vibrator 23 mounted on the upper surface of the press 9 is actuated, and the press 9
Vibration is applied to. The press 9 is guided by the guide rod 21 by the drive of the hydraulic cylinder 20 and descends.
As shown in FIG. 5, the concrete 10 in the moving hopper 8 is pushed down into the mold body 4 by the lower surface 9a of the press 9. The press 9 that has entered the upper opening 7 of the mold body 4.
Stops at the descending end limit switch LS-2, then immediately rises and stops at the ascending end limit switch LS-1. When the press 9 reaches the rising end, the press vibration is stopped.

After that, the movable hopper 8 repeats the backward movement and the forward movement of the set amount a predetermined number of times by driving the hydraulic cylinder 19, and at the position directly facing the upper opening 7 of the mold body 4, the forward end limit switch LS. Stop at -7.
In this way, the concrete 10 in the moving hopper 8 is dropped into the mold 4 even in the process in which the moving hopper 8 repeats forward and backward movements.

After that, the press vibration is restarted, and the press 9
Is lowered again, and the concrete 10 in the moving hopper 8 is pushed down into the mold body 4 by the press 9. At this stage, the concrete 10 has already been clogged to some extent in the formwork body 4, so it is not possible to press the descending end limit switch LS-2, and when the set time of the timer (2.5 seconds as an example) has elapsed. , The press 9 moves up and stops at the rising end limit switch LS-1. However, when the lower limit switch LS-2 is pressed within the set time, the moving hopper 8 is repeatedly retracted and advanced, and then the press 9 is lowered again. Below, until the falling end limit switch LS-2 is no longer pressed within the set time,
A similar process is repeated.

In this way, when the filling of the concrete 10 is completed and the press 9 reaches the rising end, the press vibration is stopped. After this, as shown in FIG. 8, the elevator 12 rises to the rising end and pushes the face plate 1 in the tubular body 5 to the press molding position. As the face plate 1 rises, the concrete 10 in the mold body 4 is pressed from below, and the excess concrete in the mold body 4 is returned to the moving hopper 8. After that, the moving hopper 8 moves backward and is stopped by the reverse end limit switch LS-6. At the time of this retreat, the upper surface 4a of the mold body 4 is scraped off by the front wall plate 8a of the moving hopper 8, and the amount of concrete 10 in the mold body 4 becomes constant.
Further, the concrete 10 is replenished from the fixed hopper 24 to the moving hopper 8 that has returned to the position just below the fixed hopper 24.

After the moving hopper 8 retreats, the press 9 starts descending and vibration is applied, and as shown in FIG.
The press 9 that re-enters the upper surface opening 7 of the
Front frame plate 4a, rear frame plate 4b, left side core plate 4c, right side core plate 4d, front side plate portion 5a, rear side plate portion 5b, left side plate portion 5c, right side plate portion 5d, and face plate of the tubular body 5. The concrete 10 is finally pressed in the space surrounded by 1 and the concrete block product P is press-molded. The press 9 is stopped by the lower limit switch LS-2.

After completion of the press forming, the press 9 is momentarily raised by the time-up of the timer for setting the press vibration time, and at that time, the locking rod 26 is moved horizontally by the operation of the core holding cylinder 25. It is taken out from the receiving hole 27a. After the formwork vibrates for a certain period of time, the press 9 descends again and pushes the tail portion of the stacked block product P, and at the same time, the elevator 12 descends and the stacked block product P is demolded. After demolding, the press 9 returns to the ascending position and stops at the ascending end limit switch LS-1, and the elevator 12 that has returned to the descending position stops at the descending end limit switch LS-3.

Upon demolding, the left side core plate 4c and the right side core plate 4d, which are connected to the frame body 4 via the horizontal pivots 28 and 29 and the suspension link 30, are the left side plate portion 5c of the tubular body 5.
Then, the lowermost end is slidably contacted with each inner surface of the right side plate portion 5d and is rotated downward so that the positioning protrusions 31 and 33 on the core plate side are separated from the positioning plates 32 and 34 on the mold body side. After the elevator 12 returns to the lower end, the face plate 1 supporting the stacked block product P is sent out to the carry-out conveyor by the forward movement of the face plate pusher, and at the same time, the decorative material 3 is arranged on the sand layer 2 in the elevator 12. A new face plate 1 is placed.
After that, the face plate pusher retracts and stops.

Here, by pulling the chain 37 by driving the hydraulic cylinders 35 and 36, the formwork main body 4 is inverted by 180 degrees about the horizontal pivot 38, and vibration is applied. As a result, the residual slag of concrete in the mold body 4 is dropped to the outside, and the left core plate 4c and the right core plate 4 are
The d rotates and is sunk in its original position. The positioning projections 31, 33 on the core plate side are positioned by the positioning plates 32, 34 on the mold body side.
The core holding hydraulic cylinder 25 is driven in reverse at the stage of engagement with the locking rod 26, and the locking rod 26 moves the horizontal receiving hole 27 of the rod receiving plate 27.
inserted in a.

After reassembling the mold body 4 in this manner, the mold body 4 is normally rotated by the reverse driving of the hydraulic cylinders 35 and 36, thereby completing one cycle of the operation of the molding machine. It should be noted that application of vibration to the press 9 can be continuously performed in the same manner as application of vibration to the mold body 4 without interruption when the press 9 is raised. After the curing and curing, the face plate 1 is removed from the building block product P, and the excess sand layer 2 which is not joined and integrated with the concrete portion is removed to obtain a decorative material-implanted concrete building block as shown in FIG.
