[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is used for, for example, a panel material formed by extruding a mixture of a thermosetting resin and cement and laminating and pressing a reinforcing material between two extruded extruded materials, particularly a concrete formwork and a floor material. And a laminated panel material containing a suitable reinforcing material.

[0002]

[Prior art]

 Conventionally, in order to prevent the concrete plate materials (concrete panel materials) used for formwork, flooring materials, etc. from spreading and increasing their strength, a curable resin is impregnated inside the molded body, or as a reinforcing material or a spreading prevention material. For example, a method of mixing fibers such as metal or resin to increase the strength of the molded body is used.

[0003]

[Problems to be solved by the device]

 However, these methods have a limit in increasing the strength of the molded product even if the manufacturing cost is high or the reinforcing fiber is mixed. For this reason, there is a drawback that the molded body becomes thicker than necessary and the weight becomes heavy. There is also a method in which a reinforcement net is attached to the formwork, and the material is poured into the formwork to give vibration to fill the formwork with the material, but this method has a low forming speed, and the attachment of the reinforcement net and the formwork are slow. It has the drawback that it takes a lot of time and effort to disassemble and assemble the product.

Further, there is a method in which the reinforcing material is inserted into the extrusion die in advance and extruded, but in this method, since the guide of the reinforcing material is crushed by the internal pressure of the die, a wide panel material cannot be extruded. Therefore, unless the fluidity of the extruded material is increased to improve the fluidity, friction (sliding resistance) increases due to the guide plate, etc., and extruded material cannot be extruded. Therefore, the extruded material has low strength after curing.

An object of the present invention is to provide a panel material which has a low cost, a wide material, a light weight and a high strength, while paying attention to the above conventional problems.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the laminated panel material with a reinforcing material according to the present invention is a laminated panel in which a reinforcing material is sandwiched and compressed between strip-shaped extruded plate materials made of a hydraulic inorganic material preformed by extrusion. In this case, a rod-shaped reinforcing bar is combined with the reinforcing material in the shape of a cross girder.

[0007]

[Action]

 A reinforcing material made by combining rod-shaped rebars in a cross-like shape is sandwiched between extruded plate materials cut to a prescribed length to form a laminated material, which is fed between pressure rolls to join the three members for compression molding. Get the wood. At this time, a part of the extruded material is inseparably locked with the reinforcing material, so that a panel material having a strong bond between the reinforcing material and the extruded plate and high strength can be obtained.

[Effect of device]

 As is clear from the above description, in the laminated panel material with reinforcing material of the present invention, the reinforcing material is sandwiched between the extruded strip materials of the hydraulic inorganic material preformed by extrusion and the joint material is compressed. It is a laminated panel material, and by using rod-shaped reinforcing bars combined in the shape of a cross in the reinforcing material, it is possible to use a general and inexpensive concrete plate material without using an extruded material such as fiber reinforced. Therefore, a low-cost panel material can be obtained. In addition, wide materials can be used, and high productivity, lightweight and high strength panel materials can be obtained. In particular, when the upper and lower thicknesses of the extruded plate are the same, the reinforcing material bites strongly into the extruded plate side, which is effective in preventing loosening. When is thicker than the lower extruded plate, it can be used as a reinforced panel material that is particularly effective against bending strength acting from the thick extruded plate side.
