Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of pairs of pressure-bonding rolls formed by extruding a mixture of a thermosetting resin and cement or the like and sandwiching a reinforcing material between two extruded extruded materials. The present invention relates to a panel material molding apparatus that is pressure-bonded between the panels.

[0002]

2. Description of the Related Art Conventionally, it has been widely practiced to extrude a plate-shaped molded article using a hydraulic material such as cement, and it is widely used particularly as a wall material for building or a mold material. By the way, since the bending strength of the above-mentioned inorganic building materials and the like is generally weaker than the compressive strength, it is disclosed in
As described in Japanese Patent No. 159306, an inorganic material in a plastic state (hereinafter referred to as an extruded material) is supplied by a screw into an extruded tube in a mold, and a bending complete portion of the extruded tube with respect to a flow direction of a plate material. A reinforcing core such as a wire mesh or a piano wire is horizontally and laterally fed into the extruding pipe through a reinforcing core guide, and is inserted from the molding die in synchronization with the extruded material during extrusion to obtain a panel material with a reinforcing material. The method is known.

Further, Japanese Patent Application Laid-Open No. 58-25908 describes a method of molding a panel material by driving. That is, in the state where the formwork on which the wire mesh-like coil material is arranged is placed on a plate-like placing table or the like, the aerated concrete slurry is cast from the bucket into the formwork. Then, the slurry in the mold is cut off along the upper edge of the mold to flatten the surface of the slurry once, and then left to stand, and a raised portion is generated in the central part due to the bubbles. When the roller, which is a pressure member, is pressed and rotated to the raised portion, the raised portion is pushed into the inside of the slurry to form a flat panel surface.

[0004]

However, in the former method as disclosed in Japanese Patent Laid-Open No. 59-159306, the reinforcing core guide is installed in the flow direction of the plate material near the bending of the extruded tube. Therefore, the flow of the extruded material flowing through the extruded tube is complicated and the flow passage is narrowed, which makes it difficult to flow. For this reason, the extruded material is limited to one with high water content. Also,
The reinforcing core can also be used only in the case of a thin wire such as a piano wire, and it is difficult to continuously produce a laminated material by synchronizing the extruded material during extrusion and the delivery speed of the reinforcing core. In addition, it has many drawbacks such as complicated die shape.

In the latter method as disclosed in Japanese Patent Laid-Open No. 58-25908, since the panel material is formed by a batch method, the molding cycle is low and a large number of workers are required, which is spent. There are drawbacks such as a large labor cost and a large work space for setting.

An object of the present invention is to pay attention to the above-mentioned conventional problems, and to expand and form a laminated material with a reinforcing material sandwiched between extruded plate materials to a predetermined plate width while crimping it between crimp rolls, Accordingly, it is an object of the present invention to provide a panel material molding apparatus capable of stably and continuously molding a panel material having a predetermined size.

[0007]

In order to achieve the above object, the apparatus for molding a panel material according to the present invention is a laminate in which a reinforcing material is sandwiched between extruded plate materials made of a hydraulic inorganic material preformed by extrusion. Material, a pressure-bonding roll for pressure-bonding the laminated material between the upper and lower rolls, and endless width-restraining belts that are between the pressure-bonding rolls and restrict expansion molding in the plate width direction during pressure-bonding of the laminated material. It is configured to be freely rotatable.

[0008]

According to the above construction, when the laminated material having the reinforcing material sandwiched between the extruded plate materials is passed between a plurality of pairs of pressure bonding rolls in which the upper and lower roller intervals are set to be constant, the upper and lower extruded plate members are pressed together. At the same time, expansion molding is performed in the feed direction of the laminated material and the plate width direction by the upper and lower pressure bonding rolls. However, the expansion forming in the plate width direction at the time of passing between the pressure bonding rolls is restricted by the endless belts rotatably provided on both sides of the pressure bonding rolls. The protrusion of the material in the feeding direction due to the expansion molding of the panel material produced in this way is cut in a later step, and thereafter transferred to a curing step according to a conventional method.
