Height-adjustable concrete mold supporting system and method for constructing concrete building

Abstract

Disclosed are a height-adjustable concrete mold supporting system and a method for constructing concrete floors and concrete walls, by which a concrete building can be easily and precisely constructed with enhanced cost-effectiveness. The system has a bottom bracket detachably disposed on a base member. First and second screw shafts are vertically assembled with the bracket. The first and the second screw shafts are movably inserted into first and second height adjusting tubes. A top mounting board is supported by the first and the second height adjusting tubes. The first and the second height adjusting tubes are fixed to the first and the second screw shafts so as to determine an adjusted space between the bracket and the mounting board.

         6 . A height-adjustable concrete mold supporting system as claimed in  claim 1 , the system further comprising a clamp detachably assembled on the mounting board to clamp a concrete wall mold.  
     
     
         7 . A height-adjustable concrete mold supporting system as claimed in  claim 6 , wherein the first and the second height adjusting tubes respectively have first and second assembling screw holes formed at upper ends thereof, the mounting board has first and second recesses through bottoms of which are formed first and second recess holes respectively, and first and second assembling screws are screwed through the first and the second recess holes into the first and the second assembling screw holes so that the mounting board is firmly held on the first and the second height adjusting tubes.  
     
     
         8 . A height-adjustable concrete mold supporting system as claimed in  claim 7 , wherein the second assembling screw has a center screw hole formed longitudinally through a center axis thereof, and the clamp has first and second bolt holes aligned with each other, the clamp being firmly assembled on the mounting board by inserting a bolt through the first and the second bolt holes and then screwing the bolt into the center screw hole.  
     
     
         9 . A height-adjustable concrete mold supporting system as claimed in  claim 8 , wherein the mounting board has a holding protuberance formed at one end thereof to hold a fixing frame, and the bolt is screwed through the first and the second bolt holes of the clamp into the center screw hole of the second assembling screw, so that the clamp is fixedly assembled on the mounting board with clamping the concrete wall mold on the fixing frame.  
     
     
         10 . A height-adjustable concrete mold supporting system as claimed in  claim 9 , wherein the concrete wall mold comprises an inner plate and an outer plate spaced with a predetermined gap from the inner plate, the inner plate having a lower end placed on an upper surface of the fixing frame.  
     
     
         11 . A method for constructing a concrete building through the use of a height-adjustable concrete mold supporting device, the method comprising the steps of: 
 a) attaching the concrete mold supporting device on a base floor;    b) adjusting the height of the concrete mold supporting device into alignment with a target reference plane; and    c) removably clamping a concrete mold on the concrete mold supporting device.    
     
     
         12 . The method for constructing a concrete building as recited in  claim 11 , further comprising the step of: applying wet concrete on the base floor to cause the concrete mold supporting device embedded in the wet concrete with its top end exposed to the outside.  
     
     
         13 . The method for constructing a concrete building as recited in  claim 12 , wherein the step of applying wet concrete is performed prior to the step c).
