DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a concrete block which is a kind of decorative block in which a color surface material different from a base material is disposed on two or three adjacent surfaces of a square block used for a curb, a color block or the like. It concerns the formwork.

[0002]

2. Description of the Related Art Conventionally, a generally known method for forming a concrete block with a surface layer is to fill an appropriate amount of a predetermined base layer material into a single block form placed in a predetermined block forming apparatus and separate the surface of the form. This method employs a system in which a constant surface layer gap is formed by pressing with a descending pressure plate, and the surface layer material is filled in the surface layer gap, compressed and solidified. As a block with a surface layer in which a surface layer material is arranged on two adjacent surfaces, there is, for example, a curb block manufacturing method disclosed in Japanese Patent Publication No. 6-73847 and a mold frame thereof.

[0003]

SUMMARY OF THE INVENTION However, the publication 2
In the method of manufacturing a block having a different surface layer on the surface, a pressing plate having a cylinder for compressing and solidifying the base layer material and the surface layer material must be arranged in two directions of the form of the rectangular block. This requires the use of a device, which is troublesome to handle and leads to an increase in the size of the device. In addition, this type is a one-piece molding process and is inefficient and is not suitable for mass production.

[0004] As a block forming method for improving efficiency by forming a block with a surface layer in which two different surface layers are arranged on two surfaces to improve the efficiency, there is also a concrete block forming method proposed by the present application and a mold frame thereof. (Patent No. 2638572
Reference). However, even in this case, the partition plate that partitions the two blocks has a complicated structure that employs a two-stage switching mechanism in which a thin plate portion and a thick plate portion that covers the thin plate portion are combined, and the thick plate portion is filled with a material for the mold. Workability is poor because it is pulled out in the horizontal direction (another direction) perpendicular to the direction (upward).
In particular, it could not be incorporated into an existing block molding machine in terms of space. Further, the thick plate portion for providing a surface layer gap is previously positioned in the mold when the base material is filled, and the thick plate portion is simply drawn out horizontally after filling, so that the surface of the base material is easily collapsed and the surface layer is easily broken. The gap was not uniform and it was difficult to hang the surface on a straight line.

In view of the above situation, the present invention fixes a partition plate for partitioning two blocks, and matches the movement of a pressing plate for a surface layer gap surrounding the partition plate to the compression, pressing, and die removing directions to the last. An object of the present invention is to provide a method for forming a concrete block with a surface layer and a formwork for solving the above-mentioned problem, which can be incorporated into an existing concrete block forming machine by setting only the vertical direction.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a concrete block molding method for arranging different surface layers on two adjacent surfaces of a square block. After filling the base material in the two frame bodies arranged side by side from above, the divided pressurizing body descends by a fixed width on both sides of the upper surface of the base material and the partition plate,
The pressing of the fixed pressing plate portions on both sides and the removal of the pressing of the central movable pressing plate portion reaching the lower end sandwiching the partition plate in a stepwise extension, and the vibration applied to the form body itself compresses by the surface layer thickness to harden the base layer, and the divided die pressing is performed. As the pressure body rises and recedes, two continuous surface gaps are formed, the surface material is filled into the two surface gaps of each square hole from above, and the surface material is lowered again. Pressing of the central movable pressing plate part whose lower surface is aligned with the pressing plate part and hardening by vibration applied to the mold body itself 2
In this method, a plurality of blocks each having a surface layer are formed at a time, and then the divided-type pressurizing body is further fed into the frame body, and the block product with a two-layer surface layer is die-cut on a bottom pallet which descends synchronously.

Further, in a concrete block molding method in which different colored surface layers are arranged on three adjacent surfaces of a rectangular block,
After filling a base material from above into a form body in which two open-topped square holes provided with a partition plate at the center received by a bottom pallet from above, the upper surface of the base material and a fixed width on both sides of the partition plate and A divided pressurizing body that descends by a fixed width at both outer ends. The central movable pressurizing plate that reaches the lower end sandwiching the partitioning plate and the central movable pressurizing plate that presses the fixed pressurizing plate on both sides and the stepwise feeding. By pressing the platen and eliminating vibrations applied to the mold body itself, it is compressed by the thickness of the surface layer to solidify the base layer.
A surface material is filled from above into the surface gaps on the three surfaces of each square hole, and the lower surface of the split-type pressurizing body for lowering the surface material again is aligned with the fixed pressing plate portions on both sides, the central movable pressing plate portion, and both outer ends. Compacted by the pressing of the movable pressure plate and the vibration applied to the formwork body 2
A plurality of blocks with a surface layer are formed at a time, and then the divided-type pressurizing body is further fed into a mold, and the blocks with a three-layer surface layer are die-cut on a bottom pallet which descends synchronously.

Further, another invention is an invention of a formwork for directly carrying out the above method, wherein a bottom pallet located on the side of the elevator with the vibrator and a partition plate at the center placed on the bottom pallet are provided. A mold body in which two square mold holes having upper and lower openings are juxtaposed, and a divided mold pressing body which can be moved up and down by a cylinder disposed above the mold body, facing each of the mold holes. It consists of a central movable pressure plate with slits that sandwiches the partition plate that is fed out stepwise by both sides of the fixed pressure plate and the sub-cylinder. The first descent facing the lower end of the partition,
The lower surface of the fixed pressing plate portion and the lower surface of the central movable pressing plate portion are aligned to take a second descent facing the lower edge of the formwork body.

The partition plate is sandwiched between the slits and reaches the lower end of the die hole. At the same time, the upper surface of the base material is compressed by a predetermined amount by the fixed pressing plate portions on both sides, and the base layer is solidified firmly in combination with the vibration applied to the form body itself.

Thereafter, when the split-type pressurizing member is raised, a continuous surface gap is formed at the receding trace of the central movable pressing plate portion and the fixed pressing plate portions on both sides, and then the surface material is filled into the surface gap. Then, the divided pressing body is lowered again. This time, the central movable pressure plate portion and the both-side fixed pressure plate portions may be lowered with the lower surfaces thereof being aligned, and the surface material may be pressed and compressed to harden the whole.

The supply box portion 16a of the base material supply means 16 for filling the base material A with the base material A (not shown) is extended forward by the operation of the horizontal cylinder 18 at the rear end (in the figure, from the right side toward the formwork body side). ) Position directly above the formwork body 1 (the entire upper opening)
And the supply box 16a itself becomes an open bottom (opening bottom) 16b, so that the internal base material A falls into the two square mold holes 4 of the mold body 1, and in this state, If the supply box portion 16a is retracted in the opposite direction, the upper opening edge 1a of the form body 1 and the lower opening edge of the supply box portion 16a are squeezed, and the filling of a certain amount of the base material A is completed. This supply box section 16
a returns to the predetermined standby position.

Next, the divided pressurizing member 9 disposed above the mold body 1 is lowered by operating a vertical cylinder 10 serving as an elevating mechanism. In this case, first, the center movable pressure plate portion 14 is previously extended by the distance corresponding to the depth of the mold body 1 by the sub cylinder 11 located at the center (see FIG. 3), and the sub cylinder 11 is locked. When the whole of the divided pressurizing body 9 is lowered by a predetermined amount by the operation of the cylinder 10, the base movable material A filled into the form body 1 from the projecting central movable pressurizing plate portion 14 is sunk. Reference numeral 14 denotes a chamfered and material-removed inclined surface 13 at both lower edges of the partition plate slit 12.
, It is located on both sides of the partition plate 7 and cuts into the base material A in a wedge-like shape with pressing to remove a fixed width, and the partition plate 7 is formed in the slit 12 at the lower end opening.

The trace remains as a gap, and this gap becomes a surface gap a. That is, the base material A filled in the form body 1 is provided on both sides of the partition plate 7 with the thickness of the central movable pressing plate portion 14 based on the thickness of the partition plate 7.
The width of the slit 12 sandwiching the is subtracted becomes the surface width b,
On the upper surface of the base layer material A, a portion compressed by the pressing of the fixed pressure plate portion 15 becomes a surface layer width b, and a surface layer gap a having two continuous surfaces is obtained as a whole. In addition, when the split-type pressurizing member 9 is raised and retracted, the base layer material A is hardened by a predetermined compression and vibration, so that the surface gap surface of the base layer portion A 'does not collapse.

Furthermore, if the supply box 19a of the surface material supply means 19 at the symmetric position containing the surface material B having a different color from the base material A is drawn forward by the operation of the horizontal cylinder 21 at the rear end ( In the drawing, from the left side toward the mold body side), the surface layer material B of the supply box portion 19a was formed in each square mold hole 4 from the opening bottom 19b just above the mold body 1 in the same manner as described above. It is filled in the surface layer gap a which is continuously provided on two surfaces, and becomes a laminated state. Thereafter, the supply box section 19a is also retracted to the predetermined standby position as described above (see FIG. 6).

Thereafter, the entire split-type pressurizing member 9 is lowered again. In this case, the central movable pressurizing plate portion 14 projecting in the above step is retracted, and the lower end of the central movable pressurizing plate portion 14 is lowered. And the lower surfaces of the fixed pressure plate portions 15 on both sides are aligned (see FIG. 6). Here, if the entire divided die pressing body 9 is lowered into the mold body 1 and the filled surface material B is pressed, the surface material B is also compressed together with the vibration applied to the mold body 1 itself as described above. The hardening is performed to form a surface layer portion B 'having two continuous surfaces. However, since the chamfered inclined surface 22 is also provided on the lower surface of the outer end of the fixed pressure plate portion 15, chamfered portions d, d are formed at both corners of the upper surface in the finished block product C.

Finally, the divided pressing body 9 (central movable pressing plate portion 14 and fixed pressing plate portion 15) lowered to the upper surface position of the form body 1 is further moved to the lower end position of the form body 1. By lowering the bottom pallet 8 in synchronism with the descending speed and operating the cylinder 5 as appropriate, the block pallet 8 is cut into a block product C having a surface layer on two solidified surfaces. 8

In another embodiment, a block with a surface layer having a surface layer on three surfaces is formed by a mold shown in FIGS. 9 to 15. In this case, the point different from the mold at the time of forming the two surfaces can be achieved only by partially changing the configuration of the split-type pressurizing body 9 (however, in this embodiment, a component having the same action as above) Are described with the same reference numerals). That is, the split-type pressurizing member 9 has a configuration in which, in addition to the central movable pressurizing plate portion 14 and the both-side fixed pressurizing plate portions 15, outer end movable pressurizing plate portions 23 are disposed at both end positions. The portion 23 can be moved up and down by a vertical sub-cylinder 24 mounted above. Further, a chamfering / material exclusion inclined surface 25 is provided at the lower end of the outer end movable pressing plate portion 23 to facilitate insertion into the base material A.

Here, the filling work of the base material A into the two side-by-side rectangular holes 4 of the form body 1 fixed to the machine body side with the bottom pallet 8 placed on the elevator 7 as the bottom frame is as follows. First, as described above, when the supply box 16a of the base material supply means 16 that slides on one of the guide supports 17 is moved to the position directly above the form body 1 by the operation of the horizontal cylinder 18, the above-mentioned condition is satisfied. The base material A contained in the supply box 16a falls into each of the square holes 4 via the opening bottom 16b, and the supply box 1

Thereafter, the divided pressurizing body 9 located above the mold body 1 is lowered by the operation of the vertical cylinder 10. In this case, the central movable pressurizing plate 14 is moved by the operation of the sub-cylinder 11 as described above. , And the outer end movable pressure plate portions 23 at both ends are also projected by a predetermined amount by the operation of the sub-cylinder 24 (see FIG. 10).

In this state, if the entire divided pressurizing body 9 is lowered by the operation of the cylinder 10, the central movable pressurizing plate portion 14 and the outer end movable pressurizing plate portion 23 projecting from the lower end are formed in the respective rectangular holes 4. Pressing into the base material A is performed. In this case, the lowering position of the central movable pressing plate portion 14 descends so as to sandwich the partition plate 3 in the same manner as described above, and the outer end movable pressing plate portion 23 descends along the form wall surface. And the lower end of the outer end movable pressing plate portion 23 with chamfering and material exclusion inclined surfaces 13 and 25.
, The base material A can be removed in a wedge-like manner by a certain width. In addition, the upper surface of the base material A is pressed by the fixed pressing plate portions 15 on both sides and compressed by a certain width, and at this time, the whole base material A is solidified in combination with the vibration applied to the form body 1 itself (see FIG. 11). ).

Here, if the whole of the split-type pressurizing member 9 moves up and retreats, traces of the central movable pressurizing plate portion 14, the outer end movable pressurizing plate portion 23 and the fixed pressurizing plate portions 15 on both sides are left.
The surface layer gap a is formed as a continuous surface, and a base layer portion A 'is obtained.

Next, as the filling operation of the surface material B, the supply box 19a of the surface material supply means 19 at the opposite position is moved toward the mold body 1 by the operation of the cylinder 21 so as to face a predetermined position. The surface material B that has entered the supply box portion 19a is dropped and filled into three surface gaps a of the base layer portion A 'in each square mold hole 4 of the mold body 1.

Thereafter, the split-type pressurizing member 9 is lowered again. At this time, the center movable pressurizing plate portion 14 and the outer end movable pressurizing plate portion 23 are not made to protrude, and the both-side fixed pressing plate portion 15 and the lower end are connected. Lower the whole body with them aligned. In this state, if the center movable pressing plate portion 14, the outer end movable pressing plate portion 23, and the both-side fixed pressing plate portion 15 press the surface layer material B and perform the compaction of the compression together with the vibration of the mold body side, Blocks with a surface layer are formed on three surfaces.

Lastly, the divided pressurizing body 9 is further lowered and re-rolled to the bottom position in the mold body 1, and at the same time, the bottom pallet 8 receiving the lower surface of the mold body 1 is moved by the operation of the cylinder 5. By appropriately lowering the amount together with the lift 7, a block product C having a surface layer on three surfaces cut out on the bottom pallet 8 is obtained (see FIG. 15).

[0033]

As described above, the method for forming a concrete block with a surface layer and the formwork of the present invention, as described above, comprise a bottom body pallet subjected to vibration that can be raised and lowered and a formwork body having two square holes formed side by side by a partition plate. A central movable pressing plate portion descending from an upper position with respect to the form body, and a fixed pressing plate portion (type in which a surface layer is attached to two adjacent surfaces) disposed on both sides thereof; A movable pressing plate portion, a fixed pressing plate portion on both sides, and an outer end movable pressing plate portion (a type in which a surface layer is attached to three adjacent surfaces) are disposed outside thereof, and each pressing plate portion is appropriately lowered in a stepwise manner. Therefore, the filling of the base material and the surface material into each square hole only needs to be performed from the upper side (one direction) of the mold body, and the central movable pressing plate portion, the both-side fixed pressing plate portion and the outer end movable. The press plate is moved only in the vertical direction. It is possible to incorporate the cleat block molding machine.

In addition, the surface gap with respect to the base material filled in the square hole is formed by a chamfering / material removing inclined surface attached to the lower end of the central movable pressing plate portion and the outer end movable pressing plate portion descending in the vertical direction. In order to eliminate wedge-shaped pressing, a fixed width (plate thickness) of surface layer gap can be created in the vertical direction without resistance even with the base material once solidified. It is possible to easily and easily form a uniform two-sided or three-sided surface gap. For this reason, the filling and lamination of the surface layer material with respect to the base layer that has undergone the primary hardening is also ensured, and the block product that is hardened by applying vibration and compression is a block that has a good finish and has a different color surface layer on two or three adjacent surfaces. Becomes

Further, since the fixed form plate is disposed in the center of the form body and two rectangular holes are formed, two blocks with a surface layer can be obtained at a stroke, and the form body becomes a mass-produced form form. Further, since the bottom of the block product is removed from the mold body, the die can be easily removed only by extending the descent of the compression-type pressurizing body for compression, and a block product that does not collapse or break is provided. It has effects such as gain.
