The fixing portion 42 of the upper floor receiving member 4 has the same configuration as the fixing portion 22 of the lower floor receiving member 2.

次に、エレベータ昇降路作業床装置設置方法について説明する。まず、下部作業床３と乗場１０４とが隣り合う場合における下部床受部材２の位置に下部床受部材２を配置して、下部床受部材２をかご用ガイドレール１０３に取り付ける（床受部材仮設工程）。下部作業床３を配置する位置としては、乗場１０４からおよそ３０ｍｍだけ下方の高さ位置が挙げられる。これは、第１単管２１１の高さ方向の寸法および下部作業床３の厚さ寸法の合計値がおよそ３０ｍｍだからである。上部作業床５は、上部作業床５の高さ位置が釣合重り１０１の上端部よりも下方となるように配置して、かご用ガイドレール１０３に取り付ける（床受部材仮設工程）。   Next, an elevator hoistway work floor apparatus installation method will be described. First, the lower floor receiving member 2 is arranged at the position of the lower floor receiving member 2 when the lower work floor 3 and the landing 104 are adjacent to each other, and the lower floor receiving member 2 is attached to the car guide rail 103 (floor receiving member). Temporary process). As a position where the lower work floor 3 is arranged, a height position below the landing 104 by about 30 mm can be mentioned. This is because the total value of the dimension in the height direction of the first single pipe 211 and the thickness dimension of the lower work floor 3 is approximately 30 mm. The upper work floor 5 is disposed so that the height position of the upper work floor 5 is below the upper end of the counterweight 101 and is attached to the car guide rail 103 (floor receiving member temporary installation step).

床受部材仮設工程の後、それぞれの支持部材１の高さ方向の寸法を最小にした状態で、昇降路１００に支持部材１を搬入する。その後、それぞれの支持部材１の高さ方向の寸法を変更するとともに、それぞれの支持部材１をピット１０２に立てる（支持部材設置工程）。   After the floor receiving member temporary installation step, the supporting member 1 is carried into the hoistway 100 in a state where the dimension in the height direction of each supporting member 1 is minimized. Then, while changing the dimension of the height direction of each support member 1, each support member 1 is stood on the pit 102 (support member installation process).

支持部材設置工程の後、それぞれの支持部材１に根がらみ部材６を取り付ける（根がらみ部材設置工程）。   After the support member installation step, the rooting member 6 is attached to each support member 1 (rooting member installation step).

根がらみ部材設置工程の後、下部床受部材２を支持部材１に取り付ける（床受部材設置工程）。上部床受部材４についても、下部床受部材２と同様にして、支持部材１に取り付ける（床受部材設置工程）。   After the root member installation step, the lower floor support member 2 is attached to the support member 1 (floor support member installation step). The upper floor receiving member 4 is also attached to the support member 1 in the same manner as the lower floor receiving member 2 (floor receiving member installation step).

また、下部床受部材２に下部作業床３を支持させ（作業床設置工程）、上部床受部材４に上部作業床５を支持させる（作業床設置工程）。以上により、エレベータ昇降路作業床装置設置方法が終了する。   Further, the lower work floor 3 is supported by the lower floor support member 2 (work floor installation process), and the upper work floor 5 is supported by the upper floor support member 4 (work floor installation process). Thus, the elevator hoistway work floor device installation method is completed.

この例では、乗場１０４は、１階の乗場となっている。エレベータ昇降路作業床装置を設置した後に、釣合重り１０１から重り板を取り外して昇降路１００から搬出する。このとき、釣合重り１０１の上部に配置されている重り板は、作業者が上部作業床５に立って取り外しを行う。釣合重り１０１の下部に配置されている重り板は、作業者が下部作業床３またはピット１０２に立って取り外しを行う。その後、釣合重り枠を昇降路１００から搬出する。このとき、釣合重り１０１をホイストによって吊り上げて、作業者は下部作業床３に立って釣合重り枠の搬出を行う。釣合重り１０１の搬入および組立は、釣合重り１０１の搬入および解体の逆の手順により行う。   In this example, the hall 104 is a hall on the first floor. After installing the elevator hoistway work floor device, the weight plate is removed from the counterweight 101 and carried out from the hoistway 100. At this time, the weight plate disposed on the upper part of the counterweight 101 is removed by the operator standing on the upper work floor 5. The weight plate disposed at the lower part of the counterweight 101 is removed by an operator standing on the lower work floor 3 or the pit 102. Thereafter, the counterweight frame is carried out from the hoistway 100. At this time, the counterweight 101 is lifted by the hoist, and the operator stands on the lower work floor 3 and carries out the counterweight frame. Carrying in and assembling the counterweight 101 is performed by the reverse procedure of carrying in and dismantling the counterweight 101.
