Description

  The present invention relates to a plate-shaped or block-shaped concrete molded body used for construction of a wall material of a building and a method for connecting the same.

Conventional concrete plates or concrete blocks using crushed stone as aggregate are widely used in civil engineering construction. At the time of construction, in the case of concrete plates, a steel frame is used, and in the case of concrete blocks, reinforcing bars are used in the air gaps, and both are filled with cement to obtain hardening strength. Further, the reinforcing joints are reinforced by reinforcing bars at the vertical and horizontal stacked joint portions of the concrete plate or concrete block, and the wall body is constructed by the adhesive solidifying function of the cement applied to the joint portions.
nothing special

  However, since the concrete molded body by the conventional stone aggregate has weight, when a concrete board or a concrete block is piled up, a sufficient foundation and a reinforcing steel bar are required. Further, due to such weight, it is difficult to transport the concrete molded body, and it is not easy to perform manual work during construction. In addition, there are problems such as frequent occurrence of damage caused by heavy collapsed materials due to the collapse caused by the earthquake.

  Therefore, the present invention was created in view of the existing circumstances as described above, and it is possible to improve the connection strength of the concrete molded body without the need for reinforcing steel bars and to reduce the weight. An object of the present invention is to provide a concrete molded body and a method for connecting the same.

  In order to solve the above-described problems, in the present invention, a concrete plate or a concrete block is divided into two thicknesses, and corrugated portions are formed on each side, and the corrugated portions can be engaged with each other. Is.

  A cloth material made of natural fiber, synthetic fiber or the like processed with an adhesive may be attached to the corrugated portion as a connecting member.

  In addition to the connection member, a hard plate material such as a stainless plate, a punching metal, or a plastic plate can be attached to the connection member as a connection reinforcing aggregate.

  The concrete board or concrete block can be formed by kneading a flexible aggregate made of plant fibers and cement with an inorganic concrete admixture.

  The flexible aggregate may be either coconut fiber, sawdust, wood chips, corn core, vermiculite, bamboo, cocoon, coarse plant powder such as tall foamed grass, or crushed sponge. it can.

  A concrete board or concrete block is divided into two thicknesses and each side is molded into a corrugated shape. The corrugated parts of the concrete molded body are made of a cloth material made of natural fiber or synthetic fiber processed with an adhesive. The connecting member to be formed can be used as a main material, and can be meshed with a connecting reinforcing aggregate formed of a hard plate such as a stainless plate, a punching metal, or a plastic plate.

  A cloth material made of natural fibers or synthetic fibers impregnated or coated with an adhesive on the corrugated portion of a concrete molded body formed by dividing a thickness of a concrete plate or concrete block into two and dividing each side into a corrugated shape. The connecting member formed in this manner is stuck, and the corrugated portions of the concrete molded body are engaged with each other so as to perform vertical and horizontal connection.

  In the concrete molded body according to the present invention configured as described above and its connection construction method, the corrugated portions of the concrete molded body are formed by a cloth material made of natural fiber or synthetic fiber processed with an adhesive. When engaging the connecting member and the connecting reinforcing aggregate made of a hard plate such as a stainless steel plate, punching metal, plastic plate, etc., the corrugated portion improves the biting between the concrete molded bodies and Sufficient strength can be developed without using reinforcing steel bars such as

  In addition, a connecting member formed of a cloth material made of natural fiber or synthetic fiber impregnated or coated with an adhesive is attached to the corrugated portion of the concrete molded body, and the corrugated portions of the concrete molded body are engaged with each other. At this time, the corrugated portion makes it possible to satisfactorily bite the concrete compacts with only an adhesive and to enable vertical and horizontal connection reinforcement. In particular, by joining the corrugated parts of such a molded body, a sufficient resistance against the shearing force along the corrugated phase direction is exhibited.

  As described above, according to the present invention, it is possible to improve the connection strength of the concrete molded body without using reinforcing steel bars, and to reduce the weight.

  That is, this is because the present invention is formed by dividing the thickness width of the concrete plate or concrete block into two parts and forming corrugated portions on each side, thereby enabling the corrugated portions to be engaged with each other. Even if the reinforcing steel bars are not used, the vertical and horizontal connection strengths of the stacked concrete molded bodies can be sufficiently improved.

  Because it is made by sticking a connecting member formed with a cloth material made of natural fiber or synthetic fiber processed with an adhesive to the corrugated part, sufficient adhesive strength can be obtained even with only the adhesive, Construction on the construction site is also easy.

  In addition to the connecting member formed of a cloth material made of natural fibers or synthetic fibers, a connecting reinforcing aggregate formed of a hard plate material such as a stainless steel plate, a punching metal, or a plastic plate is attached thereto. Compared to the use of conventional reinforcing steel bars, the weight is reduced and sufficient strength can be obtained.

  The concrete board or concrete block is made by kneading a flexible aggregate made of plant fiber and cement with an inorganic concrete admixture, so that sufficient cement bond strength can be obtained, and a lightweight and high-strength concrete board or concrete block. Is obtained. Moreover, since the inorganic concrete admixture is used, the concrete density can be increased, and a waterproof function for outdoor use can be sufficiently provided by changing the mixing ratio with cement. Furthermore, it can be molded into a soft state that is easy to nail and cut, and can be used for interiors.

  Because the flexible aggregate is one of coconut fiber, sawdust, wood chip, corn core, vermiculite, bamboo, straw, tall foamed grass, etc., or crushed sponge, A concrete board or concrete block that is friendly to the natural environment can be obtained, and can contribute to the effective use of naturally grown fibrous plants and the like.

  A concrete board or concrete block is divided into two thicknesses and each side is molded into a corrugated shape. The corrugated parts of the concrete molded body are made of a cloth material made of natural fiber or synthetic fiber processed with an adhesive. Since the connecting member to be formed is a main material and meshed with a connecting reinforcing aggregate formed of a hard plate such as stainless steel plate, punching metal, plastic plate, etc., sufficient structural strength is obtained. It is possible to easily form a concrete plate or a concrete block.

  A cloth material made of natural fibers or synthetic fibers impregnated or coated with an adhesive on the corrugated portion of a concrete molded body formed by dividing a thickness of a concrete plate or concrete block into two and dividing each side into a corrugated shape. A concrete plate or concrete that can express high strength only with an adhesive, because the connecting members formed in this way are bonded and the corrugated portions of this concrete molded body are engaged with each other. Blocks can be easily formed.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. Reference numeral 1 shown in the figure denotes a plate-like or block-like concrete molded body used for building a wall material of a building. Yes, as shown in FIG. 1, this concrete molded body 1 is a concrete plate or concrete block divided so that its thickness width is halved, and each side is divided into, for example, a small waveform, a large waveform, and an angular waveform. By forming the corrugated portions 2 in various shapes such as (see FIG. 3), the corrugated portions 2 can be engaged with each other.

  In this way, by engaging the corrugated portions 2 on one side of the two concrete molded bodies 1, the lateral connection strength is improved, and the vertical dimension of the concrete molded body 1 is combined with a step difference of 1: 1/2, so that Even if only the adhesive is used without using the reinforcing reinforcing bars, the strength similar to that of the reinforcing reinforcing bars can be expressed. Specifically, a connecting member 3 formed of a cloth material made of natural fiber, synthetic fiber or the like processed with an adhesive, for example, is attached to the corrugated portion 2 and molded.

  In addition, when further strength is required, as shown in FIG. 4, in addition to the connecting member 3 formed of a cloth material made of natural fiber or synthetic fiber processed with an adhesive, A structure in which sufficient connection reinforcement is achieved by adding a connection reinforcement aggregate 4 formed of a hard plate material such as a stainless steel plate of about 0.5 mm to 1.5 mm, punching metal, plastic plate, etc. Become.

  Further, in the present embodiment, three types of small waveform, large waveform, and angular waveform are shown as the shape of the corrugated portion 2 on one side of the concrete molded body. The invention is not limited in any way. Moreover, about the foundation part, the concrete of a normal mixture is used. Furthermore, the corrugated part 2 of the concrete molded body 1 for exterior use and the corrugated part 2 of the concrete molded body 1 for interior use may be engaged with each other.

  Moreover, in the connection construction of the concrete molded body 1, it is important that the concrete molded body 1 itself is lightweight in order to eliminate the need for a reinforcing bar. In this embodiment, the cement bone forming the concrete molded body 1 is used. For example, coconut fiber, sawdust, wood chips, vermiculite, such as corn core, which is industrial waste discharged from corn canning factories, bamboo and straw that grows in various parts of the mountainous areas of Japan, and tall foamy grass that is a problem as weeds Various types of flexible aggregates such as fiber plant coarse powder such as crushed sponge, which is a cushion material for demolished automobiles, are used instead of conventional crushed stone aggregates, and cement adhesive strength is obtained by using an inorganic concrete admixture. It has a certain strength.

  In addition, when further strength is required, in addition to the connecting member 3 formed of a cloth material made of natural fiber or synthetic fiber processed with an adhesive, a thickness of about 0.5 mm to 1.5 mm is added thereto. A connection reinforcement frame 4 formed of a hard plate material such as a thin stainless steel plate, punching metal, plastic plate or the like is provided and configured so that sufficient connection reinforcement is achieved.

And the corrugated portions 2 of the concrete molded body 1 are engaged with each other. At this time, the corrugated portion 2 can improve the biting between the concrete molded bodies 1 even with only the adhesive, and the vertical and horizontal connection reinforcement becomes possible.

  In addition, as shown in FIG. 2, when the concrete molded bodies 1 are sequentially stacked in a stepwise combination, the corrugated portions 2 of the concrete molded bodies 1 are formed with a cloth material made of natural fibers or synthetic fibers processed with an adhesive. Together with the connecting member 3 to be engaged, it is engaged through a connecting reinforcing aggregate 4 formed of a hard plate material such as a stainless plate, a punching metal, or a plastic plate. At this time, the corrugated portion 2 improves the biting between the concrete molded bodies 1 and exhibits sufficient strength without using a reinforcing reinforcing bar as in the prior art.

  In addition, although the above embodiment demonstrated the example which divided the concrete molded object 1 into 1/2 thickness width, it is not necessarily limited to dividing into 2 by this thickness dimension.
