DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete block forming die for forming a concrete block for protecting a slope.

[0002]

2. Description of the Related Art Recently, when a retaining wall for protecting a slope is constructed by a concrete block, as shown in FIG.
FIG. 5 shows a basic block A in which a rectangular base portion is continuously connected to a block main body having a truncated pyramid shape in which a lateral groove C is formed only on one opposing surface, and FIG. A construction method using a combination of a half-cut block B as shown in the drawings is widely used. Conventionally, a concrete block used in such a construction method has a rectangular cylindrical upper frame for forming the above-described rectangular base portion. In the lower part of the portion, as a portion for molding the block main body of the truncated pyramid shape, one facing surface is a fixed flat plate integrated with the upper frame portion, and the other facing surface is a recess for forming a horizontal groove. A basic mold block A is formed by a basic mold block forming exclusive form, which is followed by a substantially pyramid-shaped body frame section which is a movable mold plate that can be opened and closed, and a half cut block B is prepared separately. Made with a block-forming mold It is. The reason for using two types of molds in this way is that even if the interior of the basic mold block molding mold is partitioned by a partition plate to simultaneously form two half-cut blocks, the movable mold plate is formed as described above. This is because, since the concave portion for forming the horizontal groove is formed, the concave portion for forming the horizontal groove interferes with the partition plate when the movable mold plate is moved and opened, so that the movable mold plate cannot be moved and opened. Thus, at present, it is molded by two types of concrete block molding dies,
If a single molding machine is used for molding, it takes time and effort to replace the molds, resulting in poor production efficiency. In addition, two types of molding machines dedicated to molds must be prepared so that mold exchange is not required. However, the cost of equipment has increased, and in any case, the cost has increased.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and differs only in that a flat bottom plate without a partition plate or a bottom plate with a partition plate is used. With the same formwork, both the basic mold block and the half-cut block can be molded efficiently without any difficulty in demolding, and equipment costs can be reduced, and the molding can be performed easily and quickly without stopping the molding line for a long time. It is an object of the present invention to provide a concrete block molding die in which a frame can be changed from a basic block molding to a half block molding, and both the basic block molding and the half block molding can be efficiently performed.

[0004]

According to the present invention, there is provided a concrete block molding die according to the present invention, which has a rectangular pyramid having an upper frame formed with a lateral groove forming recess formed on one of opposing surfaces. For forming concrete blocks, a block forming form with a continuous lower frame is attached to the outer frame, concrete blocks are formed in this form, and then the form is turned over and removed. In the mold, a fixed flat template in which the lower trunk frame portion is provided continuously at the lower end of one of the opposing surfaces of the upper frame portion,
Weights are provided on the upper part of the lateral groove forming recesses, and these movable mold plates are constituted by movable mold plates which can be opened by closing side openings formed between both side edges of the fixed flat mold plate. The middle is connected to the inner surface of the outer frame via a link so as to be pivoted with the lower end abutting on the diagonally upward tapered guide surface arranged at the lower center of the outer frame, and The lower end opening is closed by a bottom mold plate slidably provided in a bottom frame provided below the bottom mold, and a substantially pyramid is always formed in a rectangular cylindrical upper frame portion by a fixed mold plate and a movable mold plate. The movable mold plate is rapidly moved and opened under the guide of the tapered guide surface by the weight of the weight when the mold form in which the lower body frame portion is continued is inverted. Is what you do.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the concrete block molding die of the present invention, when forming a basic block, the bottom plate is simply a flat plate, and when forming a half-block, the partition plate has an upper surface. It is intended to be used in place of the bottom template set up on the bottom plate. It is assumed that concave portions corresponding to the lateral groove forming concave portions of the movable mold plate are formed on both side edges.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. 1 is the outer frame 2
The frame 1 is provided with a substantially pyramid-shaped lower body frame 1b under the rectangular cylindrical upper frame 1a mounted on the outer frame 2. It has been continued. One of the opposing surfaces of the lower body frame 1b is the upper frame 1
The fixed flat plates 3 and 3 are integrally connected to the lower edge of one of the opposing side plates, while the other opposing surface is formed on the lower edge of the other opposing side plate of the upper frame 1a. On the other hand, a movable mold plate 4 having an upper edge which can be freely moved and separated is formed, and a concave portion 5 for forming a lateral groove is formed in an intermediate portion of each movable mold plate 4. Then, the lower end opening of the form 1, that is, the lower body frame 1
The lower end opening of the bottom frame 13 is closed by a bottom template 6 slidably provided in a bottom frame 13 provided below the frame 1. An obliquely upward tapered guide surface 12 for assisting pivoting of the movable mold plate 4 described later is continuously provided.

Each of the two movable mold plates 4 has its lower end engaging end 4a engaged with the concave step 14 formed at the base of the tapered guide surface 12 of the bottom frame 13 so that the movable mold plate 4 is formed at the time of molding. In the state where the plates 4 are locked so as not to be opened, the middle portion is pivotally connected to the inner surface of the outer frame 2 via links 8, and a weight 9 above the link 8 above each movable mold plate 4. The movable mold plate 4 always covers the opening formed between the both side edges of the fixed flat mold plates 3 and 3 with the weight of the weight 9 to form a substantially pyramid-shaped lower trunk frame portion 1b. The form 1
Is slightly reversed in the direction in which the engagement end 4a at the lower end and the concave step portion 14 are disengaged by the weight of the weight 9, and quickly moves under the guide of the tapered guide surface 12. The opening formed between the side edges of the fixed flat templates 3 is opened to the extent that the block formed inside the mold can be removed from the mold.

The bottom template 6 slidably supported by the bottom frame 13 is formed in a small square shape, and the bottom template 6 is attached to the bottom frame 13 with a shaft having a stopper vertically suspended therefrom. On the other hand, it is supported so that it can slide by a certain length. Further, on the upper surface of the bottom mold plate 6 described above, the mold 1
A partition plate 11 for dividing the inside into two is provided upright. On both side edges of the partition plate 11, concave portions 11a corresponding to the horizontal groove forming concave portions 5 of the movable mold plate 4 are formed. In the drawing, reference numeral 10 denotes a liner for preventing the upper frame 1a from being worn.

When the basic mold block is to be formed by using the above-described structure, the bottom mold plate 6 is formed as a flat plate having no partition plate, and is shaped like a square tube. If the mold 1 is inverted together with the outer frame 2 after filling and pressing the super-hardened concrete into the mold 1 from the frame portion 1a,
The bottom template 6 slidably supported by the bottom frame 13 with a shaft is lowered to the position shown in FIG. 3 regulated by the stopper, and at the same time, the lower end is brought into contact with the tapered guide surface 12 of the outer frame 2. The movable plate 4 pivotally attached to the inner surface of the outer frame 2 via the link 8 in a state in which the horizontal groove forming recess 5 is rapidly removed under the guide of the tapered guide surface 12 by the weight of the weight 9. Since it is moved and opened to a state where it does not hinder, the same operation as described above may be repeatedly performed, and a series of steps from molding of the basic mold block to demolding can be performed accurately and easily.

On the other hand, when the half block B as shown in FIG. 5 is to be formed, the bottom mold plate 6 is made as shown in FIG. As described above, the mold 1 is filled with the super-hardened concrete and pressurized, and then the mold 1 is turned together with the outer frame 2 to pivot the inner surface of the outer frame 2 via the link 8 in the same manner as described above. The movable mold plate 4 attached is rapidly moved under the guide of the tapered guide surface 12 by the weight of the weight 9 under the lateral groove forming recess 5.
Is moved and opened to a state where it does not interfere with the partition plate 11, that is, a state where it does not hinder removal from the mold, so that a series of steps from the molding of the two half-cut blocks B to the removal of the mold can be performed accurately and easily. That is, the movable mold plate 4 is first lowered together with the bottom mold plate 6 on which the partition plate 11 is erected and the two half-cut blocks B on which the movable mold plate 4 is formed. It moves off from the concave step part 14 and moves to the taper guide part 12 as shown in FIG. When the mold 1 is vibrated in this state, the vibration is amplified by the weight 9 attached to the upper outer surface of the movable mold plate 4, and the movable mold plate 4 is tapered through the link 8 pivotally attached to the mold 1. It is quickly opened under the guide of the guide portion 12. By this opening, the engagement between the concave portion 5 for forming the horizontal groove of the movable mold plate 4 and the concave groove C of the formed half-cut block B is released, and at the same time, the engagement with the concave portion 11a of the partition plate 11 is released. The half block B is removed from the mold block in the same manner as in the case of the basic mold block, and a series of steps from molding to removal of the mold can be performed accurately and easily. It can be formed one after another.

During the molding of the basic block A as described above, the molding is switched to the molding of the half block B,
When it is desired to switch to the molding of the basic mold block A during the molding of the above, the operation of temporarily stopping the molding line and replacing the bottom mold plate 6 from a flat plate having no partition plate to a plate provided with the partition plate 11 is performed. The replacement operation can be performed in a very short time of about 15 minutes, so that the operation can be continued without stopping the molding line for a long time.

[0012]

As is apparent from the above description, the present invention provides a block in which a substantially pyramid-shaped lower body frame part having a lateral groove forming recess formed on one of the opposing surfaces is formed in a rectangular cylindrical upper frame part. In the case where a concrete block is formed by a molding frame, a movable mold plate having a weight on an upper surface of one of the lower body frame portions, on which one of the opposing surfaces on which the lateral groove forming recess is formed, is provided. Each movable mold plate is pivotally attached to the inner surface of the outer frame via a link with its lower end abutting on the tapered guide surface of the outer frame, so that the lower end opening of the mold is closed. In addition to the case where the bottom mold plate was formed into a flat plate shape for forming a basic mold block, even when the partition plate for forming a half-cut block was erected, the mold frame was inverted for demolding. When the movable mold plate is rapidly moved and released to the extent that Therefore, the basic mold block and the half-cut block can be removed from both the basic mold block and the half-cut block using the same mold only by the difference between whether the bottom mold plate has a partition plate standing upright or a flat plate. It can be molded in a suitable manner. Furthermore, since the above-mentioned bottom mold plate can be exchanged very easily, the molding line can be easily and quickly changed to two types of block molding without stopping for a long time. Since there is no need to prepare a mold or molding machine dedicated to half block molding separately from the frame or molding machine, there are many advantages such as the facility cost can be kept low. Therefore, the present invention is very large in that it contributes to the development of the industry as a solution to the problems of the conventional concrete block molding die for protecting the slope.
