Abstract

PURPOSE:To eliminate the necessity of cutting a molded product by extruding a cement board by supplying a dashboard with a size crossing a base at the end of an extruder intermittently into the extruder. CONSTITUTION:An extruder 17 with a screw 19 in it is equipped with an extruding tube 21 having a downward pitch, a base 25 at the end, and a discharge tube 23 with a horizontal tube axis. A mold frame insertion guide 27 is inserted horizontally from the end of the extruding tube 21 into the discharge tube 23. When a hollow cement board is produced, a cylindrical core 29 the end of which is extended to the end of the base 25 and the rear of which is held by fixtures 3Oa, 30b is inserted into the guide 27. In a form 31, a dashboard is glued to the both ends of more than one reinforcing core. The dashboard with a size to be able to pass through the base 25 has a insertion hole for the core 29. An adhesive the adhesion of which decreases during the curing of a molded product is preferably used. The form 31 is sent continuously into the discharge tube 23 through the guide 27 to extrude a cement mixture. The extruded material is cured, and the dashboard is stripped.

硬化状態での保形性は良くなるが、セメント材料と補強
材との強度や切断性の違いにより、切断は著しく困難な
ものとなり、切断時に、切断部の大きな変形や損傷を生
じさせていた。A cement extrusion molded body having a metal wire or a reinforcing material framed by the metal wire has good shape retention in an uncured state extruded from the die part, but the strength and strength of the cement material and the reinforcing material are Due to the difference in the cutting property, the cutting becomes extremely difficult, and the cutting portion is largely deformed and damaged at the time of cutting.

材の廃棄処理の問題もあった。In this method, however, the work efficiency is low because the temporary cutting immediately after extrusion and the final cutting after curing and curing are performed twice. Further, since waste materials are cut off at the time of finish cutting, utilization efficiency of raw materials is low, and there is a problem of disposal processing of waste materials.
