Abstract

PROBLEM TO BE SOLVED: To eliminate a base such as a tire also in a preservation method and to enable the use of a forklift which also improve working efficiency by formingly installing a pair of cylindrical bodies for inserting the fork of a fork lift in a form body. SOLUTION: First, raw concrete is packed from the concrete packing port 11 of a form body 1 while being oscillated to accelerate solidification by applying steam for an appropriate length of time. Next, after the solidification, the forks of a fork lift are inserted into cylindrical bodies 4, 5 for inserting the first and second forks, they are transferred to a preservation place or an installation place, turned over, and placed directly on the flat ground. Thereafter, if nuts 3b are loosened, a side form 2 is made to be separated from the main body form 1, and the form body 1 is lifted by the fork lift with the forks inserted, the side form 2 is expansion-separated from the form 1 by the action of a hinge 3a and a hinge 4a so that a concrete block body 6 with an L-shaped cross section is removed smoothly from a mold and manufactured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete block molding device, and more particularly to the use of a forklift to rotate a concrete block body such as a foundation wall for attaching and fixing a fence or fence to the upper part. The present invention relates to a device that facilitates molding.

[0002]

2. Description of the Related Art Conventionally, when molding a concrete block body having a weight of about 200 kg to 2,000 kg, fresh concrete is poured into a molding die and sufficiently solidified, then the form frame is removed, and the concrete block body itself. It was common practice to lift the car with a crane or the like and gently lower it on a stand such as a tire so as not to damage it and store it. However, depending on the shape of the concrete block body, it may be inconvenient to store it. For example, an L-shaped fence must be stored in an unstable state, and in order to store it stably, There was also work to turn upside down, which was inefficient in terms of storage and working time.

[0003]

Therefore, as a result of extensive studies made by the present inventor in order to eliminate such conventional storage methods and inefficient work, the storage method does not require a stand such as a tire. In addition, the present invention has completed the concrete block molding device of the present invention that can be used in a forklift to improve work efficiency.

[0004]

That is, the present invention is a concrete block molding device characterized in that a pair of fork-inserting tubular portions of a forklift are formed in a formwork body.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION As a mold body in the present invention,
It does not matter what its specific configuration is, but it is preferable that it is composed of at least a main body form and a side form that can be slidably separated. As such a form body, the main formwork base portion, that is, filling of fresh concrete. While allowing the connecting member to penetrate back and forth at the base end located on the side opposite to the mouth side,
It is more advantageous to connect the tip end portion to the side surface mold base through a hinge. Further, as the mold body, an open mouth is formed on both sides of the main body mold, the mold for closing the open mouth is used together with the side mold, and a mold body composed of four mold members as a whole is used. It is particularly preferable that it can be removed from the mold more smoothly.

The sliding means, in other words, the advancing / retreating mechanism of the connecting member, such as a screw type or a hydraulic type, can be connected and fixed between the main body form and the side form and can be slid. It doesn't matter.

The connecting member may have any shape such as a cylindrical shape or a plate shape, and the number thereof may be one or plural. For example, the connecting members may be located at positions on both sides which are symmetrical in the base of the main body frame. It is more preferable to provide two locations in terms of stability.

The width by which the connecting member slides is
Depending on the size of the concrete block to be molded,
Normally, securing about 3 to 20 cm is sufficient for effective work.

In the present invention, as a concrete forming position of the pair of fork insertion cylindrical portions, the weight balance when the fresh concrete is filled is taken into consideration, and when turning upside down after concrete molding. In consideration of smooth rotation without excessive load on the rotation, the first fork insertion tubular part is formed at the approximate center position of the outer surface of the side form, and the second fork insertion It is particularly advantageous to form the tubular part in the body form and parallel to the first fork insertion tubular part.

In this case, if the first fork insertion tubular portion is attached to the outer surface of the side surface form via a hinge, it is turned upside down and then the fork lift is used to lift the form body, so that the connecting member is In combination with the hinge, the side form can be expanded and separated from the main form, so that a particularly good result can be obtained for more smoothly releasing the concrete block from the form.

The specific shape of the pair of fork-inserting tubular portions may correspond to the shape of the fork of the forklift. For example, if the fork of the forklift is columnar, it may be cylindrical. If the fork of the forklift has a square shape, it may have a square tubular shape.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be further described below with reference to the drawings showing one embodiment.

In FIG. 1, reference numeral 1 is a main body frame for molding a concrete block body having an L-shaped cross section, which has a concrete filling port 11 on its upper portion and an opening port 12 on its right side surface.

Reference numeral 2 denotes a side surface mold, which is a mold member for closing the opening 12 on the right side surface of the main body mold 1.

Reference numeral 3 denotes a screw-type connecting member which is pierced through a base portion of the main body formwork 1 on the side opposite to the concrete filling port 11 so as to be able to move back and forth, and its tip end is provided with a hinge 3a. It is attached to the base of the side surface form 2 and connects and fixes the main body form 1 and the side surface form 2. still,
3b is a tightening nut.

Reference numeral 4 is a cylindrical portion for inserting the first fork, and a hinge 4 is provided at an upper edge portion of the cylindrical portion at a substantially central position on an outer surface of the side surface formwork 2.
It is attached and fixed via a.
Is a tubular portion for inserting the second fork, and in the main body mold 1,
It is formed in a position parallel to the first fork insertion tubular portion.

Next, a method of molding a concrete block body will be described based on the embodiment of the present invention.
As shown in (4), fresh concrete is filled from the concrete filling port 11 of the form body while applying vibration, and steam is applied for an appropriate time to promote solidification. Then, after solidification, the forks of the forklift are inserted into the first and second fork insertion tubular parts, transported to the storage location or installation location, turned upside down, and placed directly on the flat ground. After that, the nut 3b is loosened to separate the side mold 2 from the main mold 1, as shown in FIG. By the action of the hinges 3a and 4a, the side surface form 2 is expanded and separated from the main form 1, so that the concrete block body 6 having an L-shaped cross section is smoothly released. The emptied formwork body is turned upside down again and used for the next molding.

[0018]

As described above, according to the present invention, even when ready-mixed concrete is poured (semi-dry condition), it can be transferred to the storage place and the form can be removed, so that the working time can be shortened. In addition, since the bottom of an L-shaped fence can be placed directly on the ground, mats, tires, and other rugs are not required, and when removing the form, the side form can be expanded smoothly. Since it can be opened, the product will not be scratched, and even if concrete is provided with a pattern such as a flute, these patterns will not be disturbed by the scratches and a beautiful finish can be achieved.
