Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding device for molding blocks to be laid on sidewalks, revetments of rivers, slopes of constructed land, etc. is there.

[0002]

2. Description of the Related Art As a conventional molding device for molding a comparatively thin block made of concrete, which is laid on a sidewalk,
A concrete material with fluidity is poured into the formwork, and the concrete material is filled up to the corners of the formwork by vibrating the table on which the formwork is placed with a vibrator, and then the air in the concrete material is removed. It was common for equipment to be cured in a curing room and to be demolded after the concrete material hardened to some extent, but in order to shorten the time until demolding, a concrete material with a low water content was filled in the formwork,
In recent years, an instant deblocking molding apparatus has been developed and used, in which this concrete material is pressed and solidified to be molded, and can be demolded immediately after molding. This conventional quick deblocking molding apparatus is equipped with a press mechanism for pressing the concrete material filled in the mold.

[0003]

The conventional instant demolding block molding machine molds one block at a time and cannot mold a plurality of blocks at the same time.
Therefore, in the case of manufacturing a continuous joining block having a plurality of single blocks and unitized by adjoining adjacent unit blocks with a rod-shaped connecting member at a predetermined interval by a conventional immediate deblocking molding apparatus, In this case, it is necessary to mold the unit blocks one by one and then connect the unit blocks to each other by fitting a connecting member such as a pin into a hole formed in the side surface of the unit block. However, if it is manufactured in this way, a great deal of work is required, the production efficiency is poor, and it cannot be put to practical use. Accordingly, the present invention provides a quick deblocking molding apparatus capable of forming a plurality of single blocks with a predetermined gap between adjacent single blocks and efficiently molding a continuous connection block in which adjacent single blocks are connected by a rod-shaped continuous member. The purpose is to provide.

[0004]

The present invention has been proposed in order to achieve the above object. According to claim 1, a table on which a formwork is placed and a concrete material put into the formwork are provided. In the immediate deblocking molding apparatus including a pressing mechanism for pressurizing, the mold has an upper edge of a partition wall that forms a plurality of recesses having an open upper surface to partition adjacent recesses,
A surface pallet in which a groove communicating with the recesses on both sides is formed and a rod-shaped connecting member can be loaded in the groove, and a frame body whose upper and lower surfaces are open, and which corresponds to a partition wall of the surface pallet in the open space. Characterized in that it has a partition rib arranged at a position, and comprises a main frame in which the lower end edge of the partition rib can abut against the upper edge of the partition wall when detachably assembled to the concave side of the surface pallet. An instant deblocking molding device.

According to a second aspect of the present invention, the partition rib of the main frame is provided with a draft, and the width of the lower end edge of the partition rib that abuts on the partition wall of the surface pallet is smaller than the width of the upper edge of the partition wall. Is also a large setting.

[0006]

[Function] When the concrete material is put into the concave portion and the connecting members are loaded into the respective grooves of the partition wall, the surface pallet is placed on the table, and the main frame is assembled onto the surface pallet from above. The upper part of each recess is surrounded by the partition ribs of the main frame to form an empty part for molding the unit block. In this state, when a concrete material is put into each void and the concrete material is pressed by the press mechanism, the concrete material in each void is pressed and solidified. Therefore, a plurality of unit blocks are molded at the same time, and the end portions of the connecting members are fixed in a state of being buried inside the unit blocks. Then, when the main frame is removed from the surface pallet, the thickness of the partition wall and the partition rib becomes a gap, and a plurality of unit blocks are simultaneously molded with a predetermined gap therebetween, and adjacent unit blocks are connected. A continuous joint block joined by members is completed. When the partition ribs of the main frame are drafted, the main frame can be easily demolded, and the width of the lower end edge of the partition rib that abuts the partition wall of the surface pallet is set larger than the width of the upper edge of the partition wall. Then, even if there is an error in the position between the surface pallet and the main frame, they will not be caught when the main frame is released from the mold.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a front view of the instant deblocking molding apparatus 1, FIG.
Is a side view thereof. This instant deblocking molding device 1
The table 2 is provided under the gate-shaped frame 2,
A press mechanism 5 for pressing the mold 4 on the table 3 from above is provided on the upper part of the table. The press mechanism 5 includes a frame 2
Is composed of a pressurizing hydraulic cylinder 6 provided on the upper part of the hydraulic cylinder 6, a lifting member 8 connected to a lower end of a rod 7 of the hydraulic cylinder 6 to move up and down, a vibrator 9 provided on the lifting member 8, and the like. A press plate 10 having a predetermined shape is provided on the lower surface of the elevating member 8 as a press portion for pressing the concrete material in the formwork 4. Also, Table 3 above
A vibrator 11 is provided in the lower part of the table 3, and a material supply mechanism 13 for supplying a predetermined amount of the concrete material in the hopper 12 into the formwork 4 is provided behind the table 3.

The mold 4 includes a surface pallet 16 in which a plurality of recesses 14 each having an open upper surface are formed and partition walls 15 for partitioning adjacent recesses 14 are set to have a substantially constant thickness, and a frame body whose upper and lower surfaces are open. In the open space, a partition rib 17 arranged at a position corresponding to the partition wall 15 of the surface pallet 16 is provided, and the main frame 18 is detachably assembled to the concave portion 14 side of the surface pallet 16. It is configured. And
In the form 4 shown in the drawing, 9 single blocks with a thickness of 60 mm are molded at the same time, and the overall size is 600 mm x 900 mm.
The dimensions of each part are set so that the continuous joint block can be molded.

As shown in FIG. 5, the surface pallet 16 is a thick plate-like body made of aluminum in this embodiment, and has nine recesses 14 each having an appropriate shape and size. These concave portions 14 are portions for molding the surface portion of the unit block, and their depths are set to 20 mm, respectively. The shape of the concave portion 14 can adopt an appropriate design, and the bottom portion (the surface for molding the surface portion of the unit block) is provided with appropriate concave and convex parts that are molded from an actual natural stone or imitate a natural stone. In combination with the penetration coloring described later,
It is desirable that the surface of the demolded unit block has the surface of natural stone. Further, the outer edge of the concave portion 14 located on the outer side may be set to be a substantially straight line so that the shape of the entire continuous joint block is rectangular. However, as shown in the drawings of this embodiment, the adjacent adjacent blocks are arranged in a laid state. You may set to the complementary shape of the unevenness | corrugation which can be combined with the outer edge shape of a continuous joining block.

A partition wall 15 for partitioning the concave portion 14 is a wall for forming a void that serves as a joint of the continuous joint block. In this embodiment, the thickness is set to 5 mm and the space between the unit blocks is set to 5 mm.
It is set so that a gap of mm is generated. The partition wall 1
5 shows that even if the wall thickness is set thin according to the space between the unit blocks of the continuous joint block to be molded, the lower end is entirely recessed 14
Since it is connected to the bottom of the, it is possible to secure sufficient strength to withstand the load during pressurization. Further, the partition wall 15 may be formed with a very slight draft.

Further, in the present invention, as shown in FIG. 6, a groove 19 having a substantially semicircular cross section is formed in the upper edge of the partition wall 15 and communicates with the recesses 14 on both sides. The connecting member 20 can be loaded. In addition, the groove 19
It is desirable to set the cross-sectional area of the partition ribs to be substantially equal to the cross-sectional area of the connecting member 20.
It is not necessary to form a relief groove at the lower edge of the. Also, the groove 19
When the cross-sectional shape of the groove 19 is set to be substantially the same as the cross-sectional shape of the connecting member 20 and the cross-sectional area of the groove 19 is set to be smaller than the cross-sectional area of the connecting member 20, the displacement of the loaded connecting member 20 is prevented. It is desirable to form an escape groove for accommodating the connecting member 20 protruding from the groove 19 at the lower end edge of the partition rib 17 of 18.

The connecting member 20 is a joint for joining the adjacent unit blocks across the space between the unit blocks, and is made of a flexible and elastic material, and has a pull-out preventing portion 21 at both ends. Has been formed. For example, as shown in FIG. 6, a slip-out prevention portion 2 that widens in a flange or brim shape at a portion embedded in a unit block, that is, at an end portion or in the vicinity of the end portion.
A plastic rod formed with No. 1 is preferable. The slip-out preventing portion 21 may form a barb or a ridge.
The connecting member 20 may be made of plastic such as vinyl, rubber, or metal such as aluminum.

In this embodiment, the main frame 18 is constructed so that only the inner frame 23 can be replaced by fastening the aluminum inner frame 23 to the inside of the iron outer frame 22 with bolts. A rod 26 of a mold lifting mechanism 25 is inserted and fixed in a mounting hole formed in a flange portion 24 formed on the outer circumference, and can be moved up and down by a lifting operation of the rod 26 driven by a hydraulic cylinder 27.

The inner frame 23 is a frame body whose upper and lower surfaces are opened corresponding to the molding range of the unit block, and partition ribs 17 arranged at positions corresponding to the partition walls 15 of the surface pallet 16 in the open space. Have. The partition rib 17 has a draft by increasing the thickness from the lower end toward the upper end, and the thickness (width) of the lower end edge is defined as the partition wall 1 of the surface pallet 16.
5 is set larger than the thickness (width) of the upper end, and in the embodiment shown in the drawings, the lower end thickness of the partition rib 17 is set to 8 mm while the upper end thickness of the partition wall 15 is 5 mm.

In this way, the thickness of the partition rib 17 is set to the partition wall 1
If it is set thicker than 5, the main frame 18 is lowered and the inner frame 23
When the main frame 18 and the surface pallet 16 are assembled with each other, the upper end of the thin partition wall 15 abuts within the range of the plate thickness of the lower end of the thick partition rib 17 to form an adjacent unit block forming space. The parts can be reliably divided, and there is no catch when the main frame 18 is lifted and released from the mold. Therefore, due to the difference between the thickness of the partition wall 15 and the thickness of the partition rib 17, an assembly error between the surface pallet 16 and the main frame 18 can be absorbed, and defective products can be prevented. Further, when the partition rib 17 is provided in the open space of the inner frame 23 whose upper and lower surfaces are open and the thickness of this partition rib 17 is gradually increased from the lower end to the upper end, the partition rib 1
Since it is possible to increase the strength of No. 7, it is possible to prevent cracks or damage to the partition ribs 17 even if pressure is applied to the partition ribs 17 in the pressing step described later. Further, since there is no portion where the strength is reduced unless the escape groove of the connecting member 20 is formed in the partition rib 17, the overall strength can be maintained high.

Next, the step of molding the continuous joint block by the instant deblocking molding apparatus 1 having the above-mentioned structure will be described. In the initial state, the rods 26 of the mold lifting mechanism 25 provided on the left and right of the table 3 extend upward to hold the main frame 18 in a raised state, and the lifting member 8 of the press mechanism 5 also stops in a raised state. However, the vibrator 9 of the press mechanism 5 and the vibrator 11 of the table 3 are also stopped.

First, the color pigment liquid is applied to the bottom of each recess 14 of the surface pallet 16, and after this application, the concrete material is put into each recess 14. In addition, the colored pigment liquid is applied to the concave portion 14
When applied to the inner surface, a color similar to the color of natural stone may be selected to be a single color, but a plurality of colors may be selected and appropriately applied to several places to form a so-called gradation. Further, the concrete material is a mixture of sand, cement, some water, and a binder if necessary, and what is put into the concave portion 14 is the surface portion of the unit block. It is desirable to use finer aggregates than the ones to be added.

When such a concrete material is put into the concave portion 14, the coloring pigment liquid applied to the inner surface of the concave portion 14 gradually permeates into the concrete material into which the concave portion 14 is put, so that not only the surface of the unit block but also a certain thickness can be colored. In addition, when different colored pigment liquids are applied, different blur patterns can be applied each time, and together with the irregularities of the concave portions 14, a surface closer to natural stone can be formed. It should be noted that when the concrete material is poured into the recess 14, it should not overflow.

After the concrete material is put into the recess 14, the rod-shaped connecting member 20 is loaded into the groove 19 of each partition wall 15. At this time, the bar-shaped connecting member 20 is provided with a groove 19 at substantially the center thereof.
It is desirable that the lengths of the protrusions in the left and right recesses 14 are the same in accordance with the center of the. The connecting member 2 is placed in the groove 19.
When 0 is loaded, the upper end of the thickness of the connecting member 20 slightly projects from the upper edge of the partition wall 15, but the projecting portion is crushed by the pressure of the partition rib 17 of the main frame 18, which will be described later, to expand the lateral width. Fits in the groove 19.

After the connecting member 20 is loaded in the groove 19, the surface pallet 16 is placed on the table 3. If the positioning protrusion is provided on the table 3 and the positioning protrusion is fitted in the positioning hole formed in the lower surface of the surface pallet 16, the surface pallet 16 can be easily placed at a predetermined position. There is no deviation on the way. Although the concrete material may be put into the concave portion 14 or the connecting member 20 may be loaded into the groove 19 after the surface pallet 16 is set on the table 3, the concrete material may be preliminarily set in advance as described above for safety. It is desirable that the connecting member 20 be loaded in the groove 19 while the material is being charged.

After the surface pallet 16 is set on the table 3, the mold lifting mechanism 25 is operated to lower the main frame 18. When the main frame 18 descends to a predetermined position, as shown in FIG. 4, the lower surface of the inner frame 23 is pressed against the upper surface of the surface pallet 16, and the lower end edge of the partition rib 17 crushes the upper end projecting portion of the connecting member 20. The lower edge of the partition rib 17 is pressed against the upper edge of the partition wall 15 of the surface pallet 16. Therefore, each recess 14 of the surface pallet 16 and the space surrounded by the partition ribs 17 of the inner frame 23 communicate with each other without a gap being formed in the middle.

When the main frame 18 descends to a predetermined position and is assembled to the surface pallet 16 in this manner, the material supply mechanism 13
The material supplying section 28 of the above moves forward to a predetermined position on the main frame 18 and stops on the main frame 18. By the forward movement of the material supply section 28, a rubber blade-shaped cleaning section 29 provided at the upper end of the tip of the material supply section 28 cleans the lower surface of the press plate 10. Then, when the material supply unit 28 stops on the main frame 18, the concrete material is put into the mold 4 through the upper surface openings of the inner frame 23. Further, at the same time when the material supplying mechanism 13 inputs the concrete material, the vibrator 11 on the table 3 side is actuated to give vibration to the form 4, and the injected concrete material is packed without a gap. It should be noted that, when a predetermined amount of concrete material is poured into the material supply section 28, the material supply section 28 retreats to the initial position, and in the middle of the retreat, the scraper section 30 on the lower side so-called scrapes the concrete material that has been injected into the main frame 18 to remove excess concrete material. To remove. Further, when the material supply unit 28 moves backward, the vibrator 11 on the table 3 side stops.

After the concrete material has been put into the mold 4, the elevating member 8 of the press mechanism 5 descends, and the press plates 10 provided corresponding to the respective upper surface openings of the mold 4 have their respective upper surface openings. Enter the section and press the concrete material. Simultaneously with this pressurization, the vibrator 9 on the lifting member 8 side and the vibrator 11 on the table 3 side operate.
Therefore, the concrete material preliminarily introduced into each concave portion 14 of the surface pallet 16 and the concrete material later introduced by the material supplying mechanism 13 into each empty portion of the inner frame 23 are pressed by the press plate 10 and the vibrator 9, It is pressed and solidified by the vibration of 11 and integrated, and the end of the connecting member 20 located at the boundary between both concrete materials is fixed in a unit block molded by being buried in the concrete material. Further, when the concrete material is pressurized and vibrated, the penetration of the colored pigment liquid applied to the inner surface of the recess 14 into the concrete material is promoted.

When the concrete material is molded into a unit block by pressurization and vibration in this way, the press sensor is turned on, which stops the operation of both the vibrators 9 and 11 and the pressing mechanism 5 is pressed. The pressure action is stopped. Further, when the press sensor is turned on, the rod 26 of the mold lifting mechanism 25 is lifted up part way to lift the main frame 18. At this time, the elevating member 8 of the pressing mechanism 5 does not perform the pressing action, but stops at the lowered position.
Therefore, when the mold lifting mechanism 25 lifts the main frame 18 as described above, the molded unit block is prevented from being lifted by the press plate 10 and left on the surface pallet 16,
As a result, it is demolded by being relatively extruded.

When the demolding is completed, the elevating member 8 of the pressing mechanism 5 returns to the initial position and rises, and the die elevating mechanism 25 further raises the main frame 18. Therefore, the surface pallet 16 is left on the table 3, and the molded unit blocks are left in a state of being joined by the connecting member 20, that is, as a continuous joining block. Therefore, the surface pallet 16 can be taken out from the table 3 through the lower portion of the main frame manually or by an automatic machine such as a pusher. Then, when the pallet is covered from above and the plane pallet 16 is lifted after being inverted together in this state, the continuous joint block formed on the pallet remains with the surface portion of the unit block facing upward. Then, curing is performed with the pallet placed on the pallet to complete the joint block.

By repeating the above operation, the continuous joint block can be efficiently manufactured. Then, if the molding is repeated, the partition ribs 17 of the inner frame 23 may be worn and the predetermined spacing may not be formed. Therefore, in such a case, only the inner frame 23 of the main frame 18 can be easily replaced with a new one.

[0027]

As described above, according to the present invention, not only can a plurality of unit blocks be molded at the same time with a predetermined gap therebetween, but also adjacent unit blocks can be formed into a rod shape with a predetermined interval. It can be molded in a state of being joined by the continuous member. Therefore, it is possible to efficiently manufacture a continuous joint block in which a plurality of unit blocks are connected by the connecting member. When the partition ribs of the main frame are drafted, the main frame can be easily demolded, and the width of the lower end edge of the partition rib that abuts the partition wall of the surface pallet is set larger than the width of the upper edge of the partition wall. Then, even if there is an error in the position between the surface pallet and the main frame, they will not be caught when the main frame is released from the mold. Therefore, it is possible to further improve the efficiency of manufacturing the continuous joint block and reduce the number of defective products.
