NON-SUPPORT TYPE PRESTRESSED FORM FOR CONSTRUCTING BEAM AND CONSTRUCTION STRUCTURE USING THE SAME

摘要

A non-support type prestressed beam form and an installation structure of thereof are provided to exclude the necessity of installation of timbering by transferring the dead weight of a member, concreting pressure and concrete load to two ends. A non-support type prestressed beam form(100) installed to a beam for constructing a concrete beam in a construction field for resisting the dead weight of a member, concreting pressure and concrete load without timbering includes a beam sheathing board(110) composed of two side sheathing boards(112) and a bottom sheathing board(111), an intermediate anchorage(120) fixed to the middle of the beam sheathing board and composed of a support plate supporting the bottom sheathing board of the beam sheathing board and an anchor plate expanding to support the beam sheathing board more stably, thereby to disperse the dead weight of the beam sheathing board and the pressure and load of concrete placed in the beam sheathing board to a tension member evenly, and a tension member(130) restrained to the anchor plate of the intermediate anchorage and placed along the two side sheathing boards to increase the bending stress of the beam sheathing board and to transfer the load of the middle part to two ends.
