Title: Support for mold to form building sleeve and its maintenance unit utilizing the support thereof
Inventor: JUNG WOO JIN
IPC: E04G25/04
Filed: 2019-11-11
Abstract: The present invention relates to a support of a mold for slab forming of a building and a retaining unit for slab forming of a building structure. According to the present invention, the support of a mold for slab forming of a building has upper and lower pedestals, and includes an upper member and a lower member, divided vertically. While the upper member is lifted from the lower member, a length is allowed to be stretched. Moreover, when dismantling a temporary material before curing is completed to shorten the construction period in the slab forming of a building, in order to support the applied load in the process of reaching the design standard for allowable stress of an uncured slab, a retaining unit for slab forming of a building structure, in which at least one or more supports are locally and temporarily provided on the same circumference, is denser than supports. The support comprises a lead screw installed across the lower member and the upper member from the lower pedestal in a longitudinal direction within the support, a planetary gear-type power transmission unit settled in the lower member, allowing the lead screw to pass therethrough, and receiving an external driving force transmitted from one direction to cause forward and reverse rotation of the lead screw, and a nut settled in the upper member, screw-coupled to the lead screw, and converting the forward and reverse rotation of the lead screw into a lifting motion. When the external driving force is applied to the power transmission unit, the lead screw rotates forward and reverse for the upper member to be lifted and lowered through the lower member, thereby allowing a length of the support to be adjusted steplessly. Moreover, an interlocking tube is installed across the supports of the retaining unit, so a side in one direction and a side in the other direction in each of the power transmission units embedded in the lower member of each of the opposing supports are interlocked. Thus, when an external force is applied in one direction of the power transmission unit of one support of the retaining unit, the external force is transmitted continuously and simultaneously to the power transmission unit of another support in the other direction, thereby adjusting the height steplessly at one time.
