Abstract

PROBLEM TO BE SOLVED: To obtain excellent bending strength by forming a wire net to a corrugated shape, mounting reinforcing bars to the peak parts on both and rear sides of this net longitudinally and transversely to a square box shape to form a bar arrangement structure and molding a cement board with cement by using such bar arrangement structure as a core. SOLUTION: One sheet of the wire net 1 is formed to the continuous corrugated shape. The reinforcing bars 2 are then mounted at the axis along the peaks of the corrugations and the axis to constitute the square box shape by intersecting therewith on both side of the wire net 1 apart the suitable intervals maintained therebetween. The bar arrangement structure obtd. in such a manner is fixed as the core of the board by mortar formed by kneading cement 3 and aggregate, by which the thin type cement board is obtd. This cement board is molded by exposing part of the reinforcing bars 2 and the wire net 1 on one surface on one side as a form panel for concrete placement. The cement board for heat insulation is obtd. if the cement board is molded of the aggregate expanded to a high magnification and the cement.

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cement board in which a wire net and a reinforcing bar are combined so that the cement board can have higher strength against bending, twisting and distortion. . [Prior Art] Most conventional cement plates have a reinforcing bar in the center. [Problems to be Solved by the Invention] Conventional cement plates have the following drawbacks with respect to bending, twisting, and distortion. (A) It is fragile and easily broken with a little force. (B) There is no resistance against bending, twisting, and strain. (C) It is molded only by relying on the hardening strength of cement, and there is no restoring force for bending. (D) Even if a single-layered wire mesh is contained, there is continuity when cracked, but there is no force against the strain on the surface and inside and twist, and it is easily cracked. The present invention has been made to solve these drawbacks. [Means for Solving the Problem] One wire mesh (1) is formed in a corrugated shape at the same intervals, and the reinforcing bars (2) are attached to both the front and back sides in a vertical-horizontal form with an appropriate interval. The cement plate is molded with the rebar (2) and the wire net (1) having such a structure integrated as a core. [Operation] When a force is applied from one side of the plate, a force to extend acts on the surface on the opposite side, and when it exceeds the hardening strength of the cement, it cracks or breaks. The structure of the invention is
Since the reinforcing bars (2) on both sides cooperate with each other and are constrained with cement, they greatly oppose bending and stretching force,
Since the internal wire mesh (1) is corrugated and cooperates with the reinforcing bar (2), it acts as a braces in multiple directions to fix the reinforcing bar (2) and to prevent twists and strains occurring inside. You can resist the force. In addition, when the force disappears, the entire plate is given a restoring force. [Embodiment] An embodiment of the present invention will be described below. (1) One wire mesh (1) is formed into a continuous corrugated shape. (2) Reinforcing bars (2) are attached to both sides of the wire netting (1) at appropriate intervals, and are attached to the shaft that follows the crest of the wave and the shaft that crosses this and becomes a box type. (3) Using the above structure as a core of a board, cement (3) and an aggregate are kneaded and solidified to produce a cement board. (4) As a formwork panel for concrete driving, molding is performed by exposing a part of the reinforcing bars and the wire mesh on one side. (5) When a cement board for heat insulation is molded with aggregate and foam that are foamed at a high ratio, a cement board with excellent heat insulation and sound insulation can be obtained. [Advantages of the Invention] [0007] The present invention has the above-described structure. Conventionally, in order to obtain the strength of a thin cement board, a method such as increasing the number of reinforcing bars, increasing the thickness of the board, or compression molding is used. So it became complicated and expensive. The cement board of the present invention is highly flexible and highly resilient, and can be made into a thin cement board with strength by an inexpensive and simple method. (1) It is possible to connect the reinforcing bar of the concrete body and the reinforcing bar of the cement board, and the cement board and the cast concrete can be integrated. (2) In the conventional construction method, the concrete panel was removed several days after placing the concrete, but the cement board of the present invention was integrated with the concrete after the role of the formwork, and the labor of removal was omitted. You can do it. (3) In the conventional construction method, the tile work and various finishing works were performed after the ground treatment, but the cement board of the present invention already has an ideal groundwork, and various works can be done directly. The construction period can be shortened. (4) In concrete pouring work, air bubbles and missing parts were created on the surface due to the inclusion of air, but the use of a cement plate results in a uniform surface finish. (5) Since the reinforcing bars of the cement board are incorporated inside the concrete, the cement board can be attached not only by the adhesive force between the concrete and the cement board but also by the physical force. In addition, the following will be supplemented. (B) Even if a wire mesh is used instead of a reinforcing bar, the strength is lowered but the purpose can be achieved. (B) The width and height of the wave of the wire mesh and the thickness of the reinforcing bar are changed depending on the size of the plate and the strength required for the thickness. (C) The wave shape may be round or square. (D) Reinforcing bars may be attached to the wire mesh either inside or outside the wave peaks. (E) When making a cement board for heat insulation, the inside is made of foam aggregate and cement, and the outside is made of hard aggregate such as sand and cement, and when formed, it becomes a board whose strength is known. (F) The rebar may be any rod made of iron.
