Title:
LIGHTWEIGHT CONCRETE PANEL EXTRUSION MOLDING DEVICE, AND LIGHTWEIGHT CONCRETE PANEL MANUFACTURED BY SAID EXTRUSION MOLDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/008626
Kind Code:
A1
Abstract:
Provided are a lightweight concrete panel extrusion molding device with which a groove having high shape accuracy can be reliably formed in a surface of a panel-shaped molded body that is molded from a thixotropic material mixture, and a lightweight concrete panel manufactured by said extrusion molding device. The lightweight concrete panel extrusion molding device comprises: a screw conveyer including a screw in which a blade is formed in a spiral shape around a horizontal shaft, and a columnar round bar that extends from the end on the downstream side of the screw; a hopper that feeds a material mixture onto the screw; a vibration plate that applies vibration to the material mixture fed from the hopper and molds the top surface of a panel-shaped molded body; and a thickness defining plate that defines the thickness of the molded body on the downstream side relative to the vibration plate. The vibration plate has a first protrusion that protrudes from an inner surface that contacts the material mixture and that extends from the upstream side to the downstream side. The thickness defining plate has a second protrusion that is continuous with the first protrusion, and that protrudes from an inner surface that contacts the material mixture and extends from the upstream side to the downstream side.
