Definitions

  • the present invention relates to an interior wall formwork, and more particularly to a formwork construction method for inner wall and device thereof.
  • the interior and exterior wall formworks should be erected in advance and set apart at a specific distance, so as to allow the concrete to be poured in the space between the interior and exterior wall formworks.
  • the exterior wall formwork can be removed easily without the constraint of working space.
  • the removal of the interior wall formwork is difficult due to the constraint of space and usually requires the worker to pry the formwork open, and thus it will likely generate side pressure against the wall that hasn't hardened completely, causing damage to the wall.
  • the removal of the interior wall generally needs 24 hours after the concrete hardens, and it is really time consuming.
  • the present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

  • 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.
  • 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.
  • 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.
  • 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.
  • an interior wall formwork construction method in accordance with the present invention comprises the steps of: stripping the formwork, hoisting the formwork, supporting and spreading the formwork outward.
  • the interior wall formwork 1 is hoisted by a crane.
  • the stripping and spreading of the interior wall formwork 1 are achieved by a transverse motion machine A whose drive part doesn't move with the formwork, and the driven part is connected to the formwork and makes the formwork move transversely.
  • the interior wall formwork 1 is supported by a bracket 21 that stands on a bearing block B of the interior wall and is hinged to the lower portion of the interior wall formwork 1.
  • the stripping of the interior wall formwork 1 is achieved by the rotation of the driving part of the transverse motion machine A and the linear movement of the driven part.
  • the interior wall formwork 1 can be hoisted by a crane. During the hoisting of the interior wall formwork 1, the bracket 21 will spread automatically and negotiate the obstacles on the interior wall, and will stand at a higher bearing block B on the interior wall after reaching the predetermined position.
  • the interior wall formwork 1 can be pushed outward by an opposite rotation of the driving part of the transverse motion machine A and an opposite linear movement of the driven part.
  • the interior wall formwork 1 can be connected to the exterior wall formwork, so as to allow the pouring of concrete.
  • the aforementioned transverse motion machine A is a screw driven device comprising a screw shaft 2 and a nut 3, and the nut 3 is connected to the interior wall formwork 1 via a connecting board 4.
  • an adjusting mechanism that comprises a press board 5 and a connecting member 6.
  • the nut 3 is formed at an end thereof with a flange 31.
  • the connecting board 4 is mounted on the outer periphery of the nut 3 and a side of the connecting board 4 is located at a side of the flange 31.
  • the press board 5 is mounted on the screw shaft 2, a side of the press board 5 is located at another side of the flange 31, and the press board 5 is connected to the connecting board 4 via the connecting member.
  • the screw shaft 2 is provided with an abutting assembly 7 that is used to abut against the interior wall, and the abutting assembly 7 includes a left block 71 and a right block 72 that are disposed at both sides of the flange formed at the end of screw shaft 2.
  • the upper end of the interior wall formwork 1 is connected to a transverse motion machine 9 via a connecting member 8, and the drive part of transverse motion machine 9 is connected to the screw shaft 2 via a driven part.
