Fiber reinforced cement board and foam plastic insulated stay in place forms systems with perforated metal stud for cencrete reinforced structure

Abstract

Disclosed herein is a form panel system that is capable of constructing a frame structure including a wall of a concrete-based building and a concrete structure including various retaining walls for civil-engineering works. The form panel system comprises compression cement boards disposed opposite to each other while being spaced a predetermined distance from each other, the compression cement boards being reinforced with fiber materials, reinforcing boards obtained by forming the compression cement boards in predetermined shapes, or foamed plastic heat insulating panels, and metal plate studs disposed between the compression cement boards. The metal plate studs are composed of metal plates having predetermined thicknesses and distances therebetween, which are selected depending on the durability of concrete. Each of the metal plate studs has at least one opening formed therein. Each of the metal plate studs is provided at both opposite side ends thereof with bent parts. The metal plate stud is fixed to the respective compression cement boards by means of fixing pieces, and concrete is injected and cured into the space between the compression cement boards, to which the metal plate studs are fixed and the foamed plastic heat insulating panels are attached. According to the present invention, the fiber-reinforced compression cement boards, the foamed plastic heat insulating panels, the metal plate studs having the openings are vertically or horizontally arranged without limits.

 compression cement boards disposed opposite to each other while being spaced a predetermined distance from each other, the compression cement boards being reinforced with fiber materials;    foamed plastic panels disposed at the inside surface of at least one of the opposite compression cement boards, each of the foamed plastic panels being formed by means of electric heating wires; and    metal plate studs disposed between the compression cement boards and the foamed plastic panels or between the foamed plastic panels, each of the metal plate studs being composed of a metal plate having a predetermined thickness, each of the metal plate studs having at least one opening formed therein, each of the metal plate studs being provided at both opposite side ends thereof with bent parts, wherein    the metal plate studs are fixed to the compression cement boards and the foamed plastic panels by means of fixing pieces, and concrete is injected and cured into the space between the compression cement boards and the foamed plastic panels, to which the metal plate studs are fixed, or into the space between the foamed plastic panels.    
   
   
       6 . The system as set forth in  claim 5 , further comprising: 
 at least one cement board reinforcing member linearly attached to the respective compression cement boards.    
   
   
       7 . The system as set forth in  claim 5 , wherein each of the foamed plastic panels is provided at one side thereof with supporting grooves or slits, in which the metal plate studs are fixedly fitted.  
   
   
       8 . The system as set forth in  claim 5 , wherein the metal plate studs are disposed vertically or horizontally, and a horizontal or vertical reinforcing member is inserted through at least one of the openings formed at the metal plate studs.  
   
   
       9 . The system as set forth in  claim 8 , wherein the at least one opening has a width gradually decreased in one direction such that the horizontal reinforcing member is fitted in the opening due to the weight of the horizontal reinforcing member in a wedge coupling fashion.  
   
   
       10 . The system as set forth in  claim 6 , wherein: 
 the compression cement boards, to which the foamed plastic panels are attached, are connected to each other on the same plane by means of one-plane connecting members;    the foamed plastic panels are provided at both ends thereof with supporting grooves or slits, in which the one-plane connecting members are engaged; and    the one-plane connecting members are provided at one side thereof with latching protrusions, which are engaged in the supporting grooves or slits formed at the respective foamed plastic panels connected to each other on the same plane so as to connect the foamed plastic panels to each other while concrete is prevented from leaking from the space between the foamed plastic panels connected to each other on the same plane, and concrete moves in the space between the opposite ofie-plane connecting members such that the concrete is mixed and cured.    
   
   
       11 . The system as set forth in  claim 6 , wherein:
