Formwork construction method for inner wall and device thereof

Abstract

The present invention relates to a formwork construction method for inner wall and device thereof. The construction method includes stripping, hoisting, supporting and spreading the formwork, in which, hoisting of the formwork is achieved with crane. Stripping and spreading of the formwork is achieved by a transverse motion machine making the driver rotary spreading and the driven liner spreading. The driver of machine leans against the wall, and the driven connect with the formwork. The formwork is supported on the bearing block of the inner wall by a bracket hinged under the formwork. The transverse motion machine makes use of a screw drive mechanism, which can enhance the bearing abilities and have a function of self-lock.

1 . An interior wall formwork construction method comprising: stripping an interior wall formwork; hoisting the interior wall formwork; supporting the interior wall formwork; and spreading the interior wall formwork transversely; wherein the interior wall formwork is hoisted by a crane; 
 the stripping and unfolding of the interior wall formwork are achieved by a transverse motion machine that is connected the interior wall formwork;    the interior wall formwork is supported by a bracket that stands on a bearing block of an interior wall;    the stripping of the interior wall formwork is an inward movement of the interior wall formwork achieved by the transverse motion machine, after stripping, the interior wall formwork is hoisted up, and during hoisting of the interior wall formwork, the bracket will stand on the bearing block of the interior wall after reaching a predetermined position; after being well positioned, the interior wall formwork will be moved transversely by an opposite rotation of the transverse motion machine, and after transversely spreading to a predetermined position, the interior wall formwork is connected to an exterior wall formwork.

       3 . The interior wall formwork construction method as claimed in  claim 1 , wherein the transverse motion machine is a screw driven device comprising a screw shaft and a nut, and the nut is connected to the interior wall formwork via a connecting board, between the nut and the connecting board is disposed an adjusting mechanism that comprises a press board and a connecting member, the nut is formed at an end thereof with a flange, the connecting board is mounted on an outer periphery of the nut and a side of the connecting board is located at a side of the flange, the press board is mounted on the screw shaft, a side of the press board is located at another side of the flange, and the press board is connected to the connecting board via the connecting member.  
   
   
       4 . The interior wall formwork construction method as claimed in  claim 3 , wherein the screw shaft is provided with an abutting assembly that is used to abut against an interior wall, and the abutting assembly includes a left block and a right block that are disposed at both sides of a flange formed at the end of the screw shaft.  
   
   
       5 . The interior wall formwork construction method as claimed in  claim 1 , wherein an upper end of the interior wall formwork is connected to a transverse motion machine via another connecting member, and a drive part of transverse motion machine is connected to the screw shaft via a driven part, the transverse motion machine is a screw driven device comprising a screw shaft and a nut, the upper end of the interior wall formwork is mounted to the nut by the another connecting member.  
   
   
       6 . The interior wall formwork construction method as claimed in  claim 2 , wherein the bracket is provided with an automatic spreading device for spreading the bracket outward, and the spreading device includes moment driven device, elastic-force driven device, manpower driven device, and electric driven device.  
   
   
       7 . The interior wall formwork construction method as claimed in  claim 1 , wherein a lower end of the bracket is fixed to the bearing block of the inner wall by a positioning member that has a locking groove for engaging with a locking protrusion of the bearing block.
