摘要： PURPOSE:To settle problems that bolt or screw holes in the building side are not yet executed or hard to fit to the holes of a fitting base, in the fitting base of a suspending wheel for a low story elevator to be fixed on a building member by execution of the building side. CONSTITUTION:A temporary fitting bracket 12 is fitted to a fitting base 11, and the bracket 12 is hooked on a building member 2. Holes 14 are drilled on the building member 2 at jobsite so as to fit to the holes 14 of the fitting base 11. These holes are fixed each other with bolts 14. The temporary fitting bracket 12 is removed, after fixing the fitting base 11. Hereby, by hanging the the fitting base on the building member through the temporary fitting bracket and drilling the building member at jobsite so as to fit to the holes of the fitting base, it is unnecessary to support a heavy object over an operator's head, and positioning and leveling of the fitting base can be exactly performed.

摘要： PURPOSE: To halve setting cost of jack guide rails without increasing an elevator shaft area by fixing two pieces of the jack guide rails with a building sideways against a jack central line by a set of fixtures. CONSTITUTION: Two pieces of jack guide rails are fixed with a building 5 sideways against a jack central line by a set of fixtures 3b. Tolerance is provided at a setting position by making a fixing position sideways, and it is possible to minimize an elevator shaft area. In the meantime, it is possible to complement instability of the guide rails 2 due to the fixing position made sideways as the guide rails 2 are provided in two. Additionally, as the fixtures 3b to fix the guide rails 2 on the building 2 are only one set, it is possible to make centering as regards a jack 2/3 against a conventional method.

摘要： PURPOSE:To enable deviation in X, Y directions of buildings to be absorbed by providing a connecting part of pipings between two buildings so as to absorb a phase shift between buildings and forming a piping route into a U shape so as to face both X and Y directions. CONSTITUTION:When a building 1 and a building 2 are moved in different phases, a piping 51 is fixed by a piping supporting stand 71 and transmitted to a piping 52 through a piping connecting tool 81. At this time, the piping supporting stand 71 is fixed on the building 1 side, while a piping supporting stand 73 is fixed on the building 2 side. Since the piping connecting tools 81 to 83 can be allowed to the specific angle of mutual piping, vibration between the buildings 1, 2 and phase shift caused by oscillation can be absorbed by the piping connecting tools. That is, the piping connecting tools are valid for connection of an expansion joint part. Moreover, a check part for checking the connecting tools provided between the buildings 1, 2 is provided since confirmation for oil leakage in the piping connecting tools is required. Thus, the phase shift in swing in X and Y directions between two buildings can be absorbed.

摘要： PURPOSE:To easily cope with the change of the elevator lift stroke of a building by providing an expandable stroke adjusting means restricting the lower limit of a plunger at the upper section of a gland fixed at the upper section of a cylinder. CONSTITUTION:The length D of a cylinder 3 is made slightly long in consideration of the case that the building stroke change on the elevator lift stroke A and margin strokes B, C is increased. When a stopper 8 fitted at the lower end of a plunger 4 collides with a gland 5 fitted at the upper end of the cylinder 3, the cage 2 of an elevator is located at the highest-floor level, and a base 11 adjusting the stroke of the plunger 4 is fitted on the gland 5 so that the bottom section of the cage 2 of a direct hydraulic elevator, or the bottom section of a jack pulley frame 6 of an indirect hydraulic elevator, collides with the gland 5 when the cage 2 is located at the lowest-floor level. When the length H of the adjusting base 11 is changed, the change of the building size can be coped with.
