採用されるようになって来た。(Conventional technology) In recent elevator installation work, for the purpose of improving safety and saving labor, the conventional hoisting machine, car frame, etc. are used instead of installing scaffolding in the hoistway. As a result, construction methods that involve installing guide rails and assembling entrance/exit supplies, etc., are increasingly being adopted.
そうした工法によりガイドレールを昇降路内に付設する
場合、先ず第４図に示す如く、昇降路１の上部の巻上機
（図示せず）から垂下したローブ２で吊り金具３を介し

にして、第５図乃至第７図に示す如く相互の接合端面に
形成した凹凸部４ａ、４ｂを噛み合せると共に、その両
ガイドレール４Ａ。When installing a guide rail in a hoistway using such a construction method, first, as shown in FIG. The guide rail 4A attached to the hoistway 1 is lifted into the hoistway 1. When the lower end of the guide rail 4A rises to a level near the upper end of the next guide rail 4B, which is placed on the curing plate 5 in the lower pit in the hoistway 1, as shown in the figure, the hoisting machine is stopped, and in this state, the worker brings the upper and lower guide rails 4A and 4B together, and engages the uneven portions 4a and 4b formed on the mutual joint end surfaces as shown in FIGS. 5 to 7. Also, both guide rails 4A.

継目板６により両ガイドレール４Ａ、４Ｂを連結する。Four fastening holes 5 each formed near the joint end of the flange part 4B, and four fastening holes 7 formed each in the upper and lower halves of the rectangular joint plate 6. bolt 8
By passing it through and tightening a nut 9 (see FIG. 8), both guide rails 4A and 4B are connected by the joint plate 6.

継目板６により完全に連結する。そして再びを主機を動
作させて該ガイドレール４Ａ。Each of these fastening holes 5.7 has a slightly larger diameter than the bolt 8, and with the bolt 8 and nut 9 temporarily tightened, the hoisting machine is operated to lift the upper and lower guide rails 4A, 4B a little. After checking and correcting the straightness of the rail surface, that is, after centering, the bolts 8 and nuts 9 are fully tightened to completely connect them by the joint plate 6. Then, operate the main engine again to move the guide rail 4A.

なす。4B, and connect the third guide rail 4C (see FIG. 8) to the lower end of the guide rail 4B in the same manner as before and lift it up. In this way, the guide rails are added one after another to the lower end and lifted up, to obtain the required number of guide rails, that is,
Connect and lift the number of guide rails equivalent to the total height of the hoistway 1, or in the case of split lifting, the number of guide rails equivalent to the length of the split, and attach the brackets (Fig. (not shown).
（発明が解決しようとする課題）
ところで、前述した如く巻上機によりローブ２を介して
ガイドレールを吊上げながら、その下端に継目板６で次
々とガイドレールを継足して揚重する場合、継目板６に
よりせっかく芯出し連結した上下ガイドレール間に隙間
が生じて再度手直ししなければならない不都合が発生す
る問題があった。(Problem to be Solved by the Invention) By the way, as described above, when lifting a guide rail by using a hoisting machine via the lobe 2 and adding guide rails one after another by connecting the joint plate 6 to the lower end of the guide rail, the joint There is a problem in that a gap is created between the upper and lower guide rails that have been centered and connected by the plate 6, which requires rework.
つまり、前記各ガイドレールと継目板６に形成した締結
孔５，７はいずれもボルト８より少し大径とされている
ので、上下ガイドレール相互は継目板６とのボルト８に
よる締付に伴う摩擦力Ｆによって連結されて下部荷重を
支えることになる。In other words, since the fastening holes 5 and 7 formed in each of the guide rails and the joint plate 6 are both slightly larger in diameter than the bolts 8, the upper and lower guide rails are connected to each other by the tightening of the bolts 8 with the joint plate 6. They are connected by the frictional force F and support the lower load.

Ｇよりもガイドレールの１本分の重量だけ少なくなる。This frictional force F is F-4μP, where μ is the force of tightening each of the four bolts 8 and P1 is the coefficient of friction between the guide rail and the joint plate 6. On the other hand, as shown in Fig. 8, the uppermost guide rail 4
When the total length of the second and subsequent guide rails excluding A is L, the load G applied to the joint plate 6 between the uppermost guide rail 4A and the second guide rail 4B that supports this is the unit of the guide rail. If the weight of the length is a1 and the total weight of the joint plate 6 is b, then G-aL+b...■. Further, the load applied to the joint plate 6 between the second guide rail 4B and the next third guide rail 4C is less than the above G by the weight of one guide rail.

らず非常に面倒であった。Similarly, the load applied decreases as one goes to the lower joint plate 6. This load G causes the frictional force F of the joint plate 6
If it becomes larger, a gap will be created between the upper and lower guide rails during lifting. That is, G>F is the case when L>(4μp-b)÷a...■,
When the guide rails are connected and lifted longer than this L, there is a gap δ between the upper and lower guide rails 4A and 4B as shown in FIG.
However, a gap δ' was generated between 4B and 4C, and the guide rails that had been connected to each other for centering had to be re-adjusted, which was very troublesome.
なお前述の揚重の際には巻上機の加速度αを考慮する必
要があるので、−度に揚重可能なガイドレールの長さし

揚重することができない問題があった。In addition, when lifting the load mentioned above, it is necessary to consider the acceleration α of the hoisting machine, so the length of the guide rail that can be lifted in - degrees becomes even shorter, and the desired number of guide rails can be connected and integrated. There was a problem that it could not be lifted.

The purpose is to provide an auxiliary device for rail lifting.

Just do it. In addition, since the applied load is larger at the upper guide rail joint, the guide rail lifting auxiliary device, which has more fasteners 13A, 13B installed at the joint of the upper guide rail, should be installed as the lower the joint, the more fasteners 13A, 13
Even if the number of B is reduced, the same effect as described above can be obtained.

要にできる簡便なものとなる。Since the present invention is configured as described above, by using this guide rail lifting auxiliary device to fasten the upper and lower guide rails connected by the temporary joint, the frictional force caused by the fastening of the horizontal bar and the guide rail can be reduced. This makes it possible to withstand a larger load than before, and it is now possible to connect and integrate multiple guide rails into one long length and lift them without creating gaps, making it easier to re-center and correct the guide rails after lifting. It becomes a simple thing that can be made unnecessary.
