LARGE BEAM FORMWORK TIMBERING DEVICE AND METHOD OF LARGE BEAM FORMWORK TIMBERING CONSTRUCTION

摘要

PURPOSE: To shorten the period of time for work and reduce construction cost by eliminating any disturbances to the movement of formwork or the like by supporting both the end portions of a temporary beam with a pair of triangular shaped supports which can be freely folded, and concentrating the weight of a large beam formwork on both ends of a large beam downstairs. CONSTITUTION: A vertical member 4 and a diagonal member 5 with the length adjustable by length-adjusting threads 4d, 5d are provided, a pair of both the members 4, 5 are respectively coupled with a lateral member and a brace, they are formed to a frame shape and the formwork supporting equipment for a large beam is constituted with a pair of right and left supports 3 which are formed to a frame shape and have rigidity. And the upper end portion of the vertical member 4 is fixed to a temporary beam 2 and the upper end portion of the diagonal member 5 is fixed to an inner side apart from the end portion of the temporary beam 2. Moreover, the lower end portion of the diagonal member 5 is connected to the lower portion of the vertical member 4 with a pin 5c and is assembled to a triangular shape and both end portions of the temporary beam 2 are supported, and the weight of the large beam formwork 1 is concentrated on both end portions of a large beam 8 downstairs.
