Self-launching movable scaffolding system

Abstract

A self-launching movable scaffolding system comprising: a main girder which transfers loads to supports; a front nose which transfers load of the system to support during launching; a rear nose which transfers load to a rear support during casting and launching, which is equipped with a rail system; hanger trusses which transfer load from a formwork to the main girder during casting; a rear support which provides support to the system during rebar cage installation, casting, and launching; a front support which provides support to the system during rebar cage installation and casting; a front and a middle launching support which provide support to the system during launching; a launching wagon for providing support and movement of the system; a trolley system which provides relocation to the front and middle launching supports and provides rebar cage delivery; and a formwork which is a mold for forming concrete to a shape.

1 . A self-launching movable scaffolding system comprising:
 a main girder which transfer loads to supports;   a front nose which is an extension part of the main girder located at a front end of the main girder and used to transfer load of the scaffolding system to support during launching;   a rear nose which provides a transfer of load to a rear support during casting and launching wherein the rear nose is equipped with a rail system for a rebar cage delivery and support relocation by a trolley system;   hanger trusses which provide a transfer of load from a formwork to the main girder during casting wherein the hanger trusses have a second folding function on an upper part which creates a wider opening and a higher position for allowing the scaffolding system to pass a portal pier area or other obstructions;   a rear support which provides support to the scaffolding system during rebar cage installation, casting, and launching;   a front support which provides support to the scaffolding system during rebar cage installation and casting;   a front launching support which provides support to the scaffolding system during launching;   a middle launching support which provides support to the scaffolding system during launching wherein the middle launching support can be suspended to the front nose during casting;   a launching wagon for providing support of the scaffolding system which allows the scaffolding system to move both forward and backward and further allows the scaffolding system to adjust sideways;   a trolley system which provides relocation to the middle launching support and the front launching support and further provides the rebar cage delivery; and   a formwork which is a mold for forming concrete to a shape.   
     
     
         2 . The self-launching movable scaffolding system according to  claim 1  wherein the rear support which provides support to the scaffolding system during rebar cage installation, casting, and launching can be opened at a center for the rebar cage to pass through. 
     
     
         3 . The self-launching movable scaffolding system according to  claim 1  wherein the front support which provides support to the scaffolding system during rebar cage installation and casting can be opened at a center for the rebar cage to pass through. 
     
     
         4 . The self-launching movable scaffolding system according to  claim 1  wherein the formwork is supported by a formwork support frame with no hanging bars for its hanging. 
     
     
         5 . The self-launching movable scaffolding system according to  claim 1  further comprising rear support main jacks which are activated and deactivated in order to transfer load to an existing bridge and pass load through express rollers to the existing bridge, respectively. 
     
     
         6 . The self-launching movable scaffolding system according to  claim 1  further comprising rear support side shifting cylinders which are equipped at a top of the rear support and the main girder, used for transverse adjusting of the main girder during launching to pass through curve spans and for transverse adjusting of the rear support itself before casting. 
     
     
         7 . The self-launching movable scaffolding system according to  claim 1  wherein:
 the front launching support is set and secured on a pier top with the launching wagon at the top which allows the front nose and the main girder to glide or move over to a new set position; and 
 the front launching support can be dissembled from a pier and suspended to the front nose in order to relocate to a next pier. 
 
     
     
         8 . The self-launching movable scaffolding system according to  claim 1  further comprising tension bars which are installed and engaged to the front support in order to confine a deflection of the front support during casting, after placing of the rebar cage. 
     
     
         9 . The self-launching movable scaffolding system according to  claim 1  further comprising front support main jacks which are activated to transfer load from the main girder to the front support during casting. 
     
     
         10 . The self-launching movable scaffolding system according to  claim 1  further comprising front support legs which provide a transfer of load further to a column footing. 
     
     
         11 . The self-launching movable scaffolding system according to  claim 1  further comprising front support side shifting cylinders which are equipped at a top of the front support and the main girder in order to allow transverse adjusting of the main girder. 
     
     
         12 . The self-launching movable scaffolding system according to  claim 1  further comprising a mono-rail which is set along the rear nose, the main girder, the front nose and an electrical lifting hoist.
