Abstract

Disclosed is a passenger conveyor which has excellent manufacturability of a frame body, and is easy to renew. Specifically disclosed is a passenger conveyor which is provided with: a frame body that is disposed in a building structure; platform floors that are provided to both ends in the longitudinal direction of the frame body; a footstep that is endlessly connected between the platform floors so as to circulate/turn; a drive device that drives the footstep; and railings that face right and left in the direction in which the footstep turns, wherein the frame body has a structure in which a plurality of blocks divided in the longitudinal direction are interconnected, and each of the blocks has an upper chord member, a lower chord member, a longitudinal member, and a diagonal member, and in which the longitudinal member and the diagonal member are fastened to the upper chord member and the lower chord member by reamer bolts.

Description

technical field [0001] The invention relates to passenger conveying equipment such as escalators and electric passages, and in particular to a frame structure of the passenger conveying equipment. Background technique [0002] In known passenger conveying equipment, as in Patent Document 1 figure 2 and of Patent Document 2 figure 1 and figure 2 etc., the frame body for an escalator is formed by connecting a plurality of frame body segments divided in the longitudinal direction with bolts, and each of the above frame body segments has an upper chord material and a lower chord material made of L-shaped steel. , longitudinal materials, and oblique materials, which are overlapped to form a truss shape, and the ends of the overlapped parts are connected by electric welding.
