In detail, the rail material 3 is comprised from the T-shaped steel which has a length comparable as a floor height dimension, and is arrange | positioned as a pair so that the webs 14 may be made to oppose. Further, the hydraulic cylinder 5 is disposed at an intermediate portion between the pair of rail members 3 arranged side by side. The hydraulic cylinder 5 is connected to a hydraulic unit 15 installed on the base portion 7 so that the rod 5a can be vertically expanded and contracted. That is, the rail member 3a at the lowermost end and the hydraulic cylinder 5 can be arranged by construction work using the base portion 7 as a work place, and are in a completed state as designed at the end of this construction (see FIG. 10). ).

  Next, the platform 16 is attached to the rail member 33 (the lowermost rail member 3a) that is positioned and fixed so as to be movable up and down via the guide portion 9, and the upper end portion of the rod 5a of the hydraulic cylinder 5 is attached to the platform 16. Is fixed to the vertical frame portion 16a so that the platform 16 is positioned and fixed by the operation of the hydraulic cylinder 5, and the horizontal position and posture of the platform 16 are maintained while maintaining the horizontal position and posture. A ready state is set (see FIG. 1). Here, at the time of this construction (when the guide rail 2 is installed), the casing 17 is not placed and only the platform 16 exists as shown in FIG. A work table portion 18 is formed at the upper end portion of the frame portion 16a. The work table portion 18 is formed so as to be supported at the upper end of the vertical frame portion 16a in a cantilever manner via a brace 23 or the like, and to be positioned above the horizontal frame portion 16b. The work platform 18 may be formed on the platform 16 with the platform 16 attached to the lowermost rail member 3a via the guide 9 or the platform 16 via the guide 9. You may perform before attaching to the rail material 3a of the lowest end.

  Next, by operating the hydraulic cylinder 5 and extending the rod 5a, the platform 16 is raised along the rail member 3a at the lowermost end, and the platform 16 is moved to its work table portion 18 as shown in FIGS. Is in an upward projecting state positioned above the upper end position of the lowermost rail member 3a.

  The platform 16 in the upward projecting state is horizontal by the cooperation of the guide by the lowermost rail member 3a with respect to the guide portion 9 provided in the vertical frame portion 16a and the support by the hydraulic cylinder 5 in which the rod 5a is fixed to the platform 16. The position and orientation of the direction can be maintained.

  Here, when the platform 16 is in the upward projecting state, the guide portion 9 is below the upper end position of the rail member 33 (the lowermost rail member 3a) positioned and fixed in the vertical frame portion 16a of the platform 16. It is provided at the position. Specifically, in this example, the guide portion 9 is composed of a lower guide portion 9b provided at the lower end portion of the vertical frame portion 16a and a central guide portion 9a provided at the middle portion of the vertical frame portion 16a. Has been. And the center part guide part 9a is removed after the installation work of the rail material 3, that is, it is the construction guide part 90 used only at the time of the installation work of the rail material 3. On the other hand, the lower guide portion 9b is a use guide portion 91 that is also used in the elevator device 1 in a completed state.

  In addition, at the time of the construction work, the retaining member 10 that prevents the rail member 33 (the lowermost rail member 3a) positioned and fixed from coming off upward is detachably attached to the lowermost rail member 3a. (See FIG. 2). In a state where the rail material 3 is not connected above the lowermost rail material 3a, the guide portion 9 of the raised platform 16 may come out from the lowermost rail material 3a. The above-mentioned fear can be eliminated by providing, that is, the safety of construction is ensured.

  Next, as shown in FIG. 1, a new rail member 34 is formed on the upper side of the rail member 33 (the lowermost rail member 3 a) positioned and fixed above using the work platform 18 of the platform 16 in the upward projecting state. (Upper one rail member 3b) is connected and positioned and fixed to the building frame 8 which is a structure part of the elevator hoistway 6. This work is performed as follows, for example.

  First, as shown in FIG. 2, a worker A (hereinafter referred to as a first worker A) riding on the work platform 18 of the platform 16 in the upward projecting state fixes a new rail member 34 to the building housing 8. The bracket 13 is fixed to the building housing 8. Next, as shown in FIG. 3, a new worker B (hereinafter referred to as a second worker B) rides on the horizontal frame portion 16b of the platform 16 in the upward projecting state, and a new rail member 34 is placed on the first and second rails 34. The first worker A temporarily fixes the new rail member 34 to the bracket 13 by the cooperation of the workers A and B from above the lowermost rail member 3a, and the second worker B sets a new rail. The lower end of the material 34 and the upper end of the lowermost rail material 3a are temporarily connected. Next, as shown in FIG. 4, after the vertical alignment (centering) of the new rail member 34 is performed using the vertical alignment jig 20 such as a downward swing, the first worker A sets a new rail. The material 34 is permanently fixed (positioned and fixed) to the bracket 13, and the second worker B fully connects the lower end of the new rail material 34 and the upper end of the lowermost rail material 3 a. As a result, the rail member 3a at the lowermost end and the rail member 3b one level above are in a state of being positioned and fixed to the building frame 8 in a state of being integrally connected. The integrated body of the lowermost rail member 3a positioned and fixed and the upper rail member 3b becomes a rail member 33 positioned and fixed earlier with respect to a new rail member 34 to be connected later. The rail member 33 positioned and fixed earlier (the integrated member of the lowermost rail member 3a and the upper one rail member 3b) is within the range of completion of the installation work of the rail member 3 finished as designed.

  Here, in the operation of connecting the new rail member 3 to the rail member 33 previously positioned and fixed and positioning and fixing it to the building frame 8 on the side of the elevator hoistway 6, it projects upward as described above. The guide portion 9 is provided only at a position below the upper end position of the rail member 33 positioned and fixed first in the platform 16 in the state, that is, the upper end position of the rail member 33 positioned and fixed first in the platform 16 in the upward projecting state. Since the guide portion 9 does not exist at a position higher than the guide portion 9, the guide portion 9 does not interfere with the approach work of the new rail material 34 to the rail material 33 previously positioned and fixed, Workability is improved. Further, if the height dimension of the horizontal frame portion 16b of the platform 16 and the work table portion 18 are formed to be approximately the same as the floor height dimension of the building, the first worker A and the second worker B can get on and off each floor. It is convenient to be able to get on from the mouth 11 respectively. Further, a ladder may be formed between the horizontal frame portion 16b and the work table portion 18 so that the horizontal frame portion 16b and the work table portion 18 can be moved back and forth. In this case, construction is performed by one worker. It can also be made.

  Next, as shown in FIG. 5, the retaining member 10 is removed from the lowermost rail member 3a, and the guide member 9 is prevented from being removed from the rail member 3b that is connected to the lowermost rail member 3a. After securing the safety by attaching a new stop member 10, the platform 16 is raised along the upper rail member 3 b connected to the lowermost rail member 3 a, and the rail is positioned and fixed at the end. The platform 16 is made to project upward with respect to the material 33 (one body of the rail material 3a at the lowermost end and the rail material 3b one level above). The newly attached retaining member 10 is a bracket for fixing the rail material 3 (one rail material 3b at this time) constituting the upper end portion of the rail material 33 previously positioned and fixed to the building housing 8. 13 is attached. Then, by using the work platform portion 18 of the platform 16 in the upward projecting state, a new rail member 34 to be the rail member 3c (see FIG. 11) two above the rail member 3a at the lowermost end is firstly attached. The rail member 33 is positioned and fixed (connected to the lowermost rail member 3a and the upper one rail member 3b) and fixed to the building housing 8. The integrated rail material 33 (the integrated body of the lowermost rail material 3a and the upper rail material 3b) and the above-mentioned upper rail material 3c are newly connected to each other after that. Thus, the rail member 33 is positioned and fixed to the rail member 34.

  In this way, the retaining member 10 is replaced to prevent the platform 16 from being pulled upward from the rail member 33 that has been positioned and fixed earlier, and the platform 16 is raised by the hydraulic cylinder 5 to be positioned and fixed first. The operation (FIGS. 2 to 5) of making the upper protruding state with respect to the rail material 33, connecting the new rail material 34 to the upper side of the rail material 33 previously positioned and fixed, and positioning and fixing to the building housing 8 (FIGS. 2 to 5) is repeated as appropriate. As a result, all the rail members 3 constituting the guide rails 2 are connected and positioned and fixed to the building housing 8, and the arrangement and installation of the rail members 3 in the entire range of the guide rails 2 are completed.

  In this way, the platform 16 is raised by the operation of the hydraulic cylinder 5 which is an elevator driving device, so that the work table portion 18 is in an upward projecting state positioned above the upper end position of the rail member 33 positioned and fixed earlier. Since the work table portion 18 in the upward projecting state is used, the new rail material 34 is connected to the upper side of the rail material 33 previously positioned and fixed, and the positioning is fixed to the structural portion of the elevator hoistway 6. There is no need for a temporary scaffold constructed for the elevator hoistway 6 as in the prior art, and a plurality of rail members 3 are moved from below by using a platform 16 that moves up and down by the operation of the hydraulic cylinder 5 used as it is in the elevator apparatus 1. The guide rails 2 can be arranged in the elevator hoistway 6 so as to be added in order, which is good Workability is ensured.

  Specifically, in the upward projecting state of the platform 16, the platform 16 is moved in the horizontal direction by the cooperation of the guide by the rail member 33 positioned and fixed to the guide portion 9 and the support by the hydraulic cylinder 5 to which the rod 5 a is fixed. In other words, since the guide rail 2 temporarily fixed to the building housing 8 is not required to suppress the rotational moment of the platform 16 as in the prior art, the elevator and the position are maintained. There is no need for a temporary scaffold constructed in the hoistway 6.

  In addition, when the guide rail 2 is installed and installed, the rail material 3a that is necessarily positioned and fixed first is necessarily arranged on the elevator hoistway 6 of the rail material 3a at the lowermost end, which is an elevator driving device. Along with the arrangement of the hydraulic cylinder 5, the base part 7 of the elevator hoistway 6 can be used as a work place, and in this respect as well, a temporary scaffold constructed for the elevator hoistway 6 as in the prior art is not required, Good workability is ensured.

  In addition, as the retaining member 10 provided to prevent the platform 16 from coming off from the rail member 33 positioned and fixed first, a type that is detachably attached to the rail member 33 positioned and fixed first, A type in which the rail member 33 that has been positioned and fixed first is detachably attached to the bracket 13 that is fixed to the building housing 8 is appropriately used. In the latter case, the bracket 13 is a member that is not limited in shape, unlike the rail material 3 that is formed in a vertically long shape, as in the present example, a form material having an L-shaped cross section that is long in the left and right is used. That is, since the retaining member 10 can be fixed to the bracket 13 so as to be hooked up and down, it is directed upward of the guide portion 9 to the guide contact portion 41 described later. It is possible to secure a strong mounting strength so as to have a good resistance against a collision.

  Specifically, the retaining member 10 of the type attached to the bracket 13 is attached to the bracket 13 for fixing the rail member 3 to the structure of the elevator hoistway 6 as shown in FIGS. A bracket attaching portion 40 and a guide abutting portion 41 extending from the bracket attaching portion 40 and abutting on the guide portion 9 provided on the platform 16 in the upward projecting state to restrict the upward movement thereof.
