Title:
MEMBRANE ROOF STRETCHING SPREADER
Document Type and Number:
Japanese Patent JP2873550
Kind Code:
B2
Abstract:
PURPOSE: To maintain the engagement of beams with a running roller by connecting a running roller to a guide member, which contacts with the side surface of a beam in the energizing condition, and appropriately moving the running roller in the width-wise direction through the guide member according to distance between the beams.
CONSTITUTION: When a running roller 42 of each running roller mechanism 47, 60 is set on a flange A of beams A adjacent to each other so as to be rolled, a guide member 43 abuts on the side surface in the energizing condition. A spreader B is raised along the beam A, and a membranous material supplying drum 4 is rotated so as to supply the membranous material 12 to the beam A, and the membranous material is stretched between the adjacent beams A through a sheet fixing fitting 68. At the time of stretching, in the case where the space between the beams A is different from each other, a ratchet handle 22 is turned, and a screw rod 19 is rotated so that a nut 29 pushes an engaging member 27, and the running roller mechanisms 47, 60 and a movable body 48 are moved along a rail 17 so as to adjust the space between the running roller mechanisms 47, 60.
