The support member 8b has a substantially C-shaped notch 81b into which the end of the rod-shaped body 3a is inserted in two upper and lower stages, and the support 82b that receives the end of the rod-shaped body 3a by these notches 81b. It is formed in two stages.
[0010]
Next, an operation procedure for curing the hall opening 1 with the above-described elevator hall opening curing apparatus will be described.
First, as shown in FIG. 1, a pair of support bodies 8 are attached to the front walls 7a located on both sides in the vicinity of the top of the landing opening 1 so as to have substantially the same height. As shown in FIG. 4, each support 8 is fixed by screwing into the front wall 7a while inserting a fixing tool such as a bolt into the insertion hole 81a of the fixing member 8a. At this time, the support 8 and the fixing member 8a of the support 8 are supported. The member 8b is adjusted by the hinge portion 8c so that the opening angle is approximately 90 degrees. The mounting position of the pair of support bodies 8 positioned at the uppermost part is set such that one of the support parts 82b provided in two upper and lower stages is higher than the top part of the landing opening 1. In addition, a pair of support bodies 8 are similarly attached so that the height of the hall opening 1 in the height direction is substantially equal to the front wall 7a located on both sides thereof.
[0011]
Then, the both ends of the rod-shaped body 3a attached to the uppermost part of the curing sheet 2 are each supported between the support parts 82b of a pair of support body 8 of an upper part. When both ends of the rod-shaped body 3b attached to the intermediate portion of the curing sheet 2 are similarly supported between the support portions 82b of the pair of support bodies 8 provided at the intermediate portion in the height direction of the landing opening 1, While preventing the curing sheet 2 from being displaced and exposing the landing opening 1, the landing opening 1 can be completely closed with the curing sheet 2 without a gap.
