Can be slid by a series of operations.

Further, ground rolling elements 31, 31a rolling on the upper surface of the temporary scaffold A are provided at the tip ends of the slidable closing doors 3, 3a, 3b.
Alternatively, one or both of the suspension traveling bodies 50, 50a, and 50b that are movable with respect to the beam H suspended over the opening W are provided, so that the closing door 3, which is slidable with respect to the temporary scaffold A side, 3a,
The distal end of 3b can be slidably supported, so that the slidable closing doors 3, 3a, 3b can be slidably supported at both ends, and can be smoothly slid back and forth.

Further, the guide rails 9, 10 are moved to the closed doors 3, 3a.
The guide rollers 22, 22a are provided at the upper and lower corners on the base end side of the slidable closing doors 3, 3a, 3b, so that the slidable closing doors 3, 3a, 3b are adjacent to each other. Since the upper and lower doors 3a, 3b, and 3c can be regulated at two positions, the door 3 can be slid freely when sliding.
It is possible to prevent the inward and outward swings of 3a and 3b.

Also, the slidable closing doors 3, 3a, 3b are
The sliding doors 3, 3 a, 3 b are composed of the panel bodies 4, 4 a, 4 b and the traveling pillars 7, 7 a, 7 b disposed on the tip side of the panel bodies 4, 4 a, 4 b. Body 4, 4
a, 4b and the traveling pillars 7, 7a, 7b can be disassembled and transported and stored, thereby facilitating transportation work, storage and management, and replacing only damaged parts,
Economic efficiency can be improved.

In addition, the ground running body 31 is attached to the running pillars 7, 7a and 7b.
31a or one or both of the suspended traveling bodies 50, 50a, and 50b are fixed, so that when the suspended form is particularly suspended, the slidable closing doors 3, 3a, 3b in the assembled state are heavy and heavy labor is required. However, after suspending only the relatively light running columns 7, 7a, 7b on the beam H, the relatively large panel bodies 4, 4a, 4b can be attached to the running columns 7, 7a, 7b. The installation work of the sliding door 1 can be easily performed.

A fixed closing door 3c is provided on the panel body 4c and on the temporary elevator E side at four corners of the panel body 4c.
Since it is constituted by the fixing members 5, 5a... To the pair of vertical frames 6, 6a provided on the side of the opening W, the work of attaching and detaching the closing door 3c to and from the opening W can be facilitated.

The traveling columns 7, 7a, 7b are connected to a pair of columns 3
Since the upper and lower connecting plates 32 and 32a are integrally formed at intervals with the upper and lower connecting plates 32 and 32a, the innermost slidable closing door 3 without exposing a locking device main body 61 and a retaining rod 61a to be described later to the outside. The front ends of the panel bodies 4, 4a, 4b are arranged between the columns 30, 30a of the traveling pillars 7, 7a, 7b, and the panel bodies are attached to the traveling pillars 7, 7a, 7b. 4, 4a, 4b are fixed, and the column 30 and the panel body 4a, 4b on the side of the temporary scaffold A are fixed.
In the meantime, the gaps S and Sa through which all the panel bodies 4, 4a on the temporary scaffold A side can pass are formed with respect to the panel bodies 4a, 4b, so that the adjacent slidable closing doors 3, 3a, 3b are formed. The running pillars 7, 7a, 7b do not hinder sliding, and the overlapping dimension of the panel bodies 4, 4a, 4b in the closed state can be reduced.

The distance between the pair of columns 30, 30a in the respective traveling columns 7, 7a, 7b of the slidable closing doors 3, 3a, 3b is made equal, and the traveling columns 7, 7a, 7b are also provided. The gaps S, Sa were formed by sequentially shifting the fixing positions of the panel bodies 4, 4a, 4b in the above, so that all the traveling pillars 7, 7a, 7b
Can be reciprocated on the same orbit.

Further, since a pair of rollers 53, 53a that roll with respect to the upper and lower edges of the beam H are disposed on the suspension traveling bodies 50, 50a, 50b, the slidable closing doors 3, 3a, Since the position of 3b is restricted at the upper and lower edges of the beam H, the sliding doors 3, 3a, 3b that are slidable during sliding can be prevented from swinging in and out.

The panel bodies 4, 4a, 4b, 4c of the slidable closing doors 3, 3a, 3b and the fixed closing door 3c are
The fixing members 5, 5a... And the guide rollers 22, 22a can be detachably attached to the four corners, and the traveling pillars 7, 7a, 7b can be attached to either one of both ends. ... can be used as a common member, so that it can be used for either of the closing doors 3, 3a of the left and right door portions 2 and 2a, and also for any of the closing doors 3, 3a. Therefore, no matter how the parts are assembled at the time of assembly, the slide door 1 can be completed as long as the guide rollers 22, 22a and the traveling columns 7, 7a, 7b are properly installed.

Also, the temporary elevator E is confirmed to be stopped and unlocked, and when the closing doors 3, 3a, 3b and 3c are completely closed, the temporary elevator E is automatically locked and controlled so that the temporary elevator E can be raised and lowered. Since the temporary elevator E does not move unless the sliding door 1 is properly closed because the locking device 60 is provided, it is possible to prevent the sliding door 1 from being forgotten to be closed. It is possible to further improve the effect of preventing a disaster from occurring due to a fall of a worker or material.

A locking device 60 is provided on one of the traveling columns 7 of the closing door 3 on the temporary scaffold side of the left and right doors 2 and 2a, and on the other traveling column 7. The locking device main body 61 has a vertically extending hanging rod joint 67 formed on one end surface of a horizontally long cylindrical casing 62 fixed to the mounting rod 91. When the is closed, the locking rod 61a can be reliably positioned at a position where the locking claw 72 described later locks.

A base end of a lock claw 72 provided with a concave portion 71 at a position corresponding to the locking rod joint portion 67 is pivotally connected to the casing 62, and a drive portion 73 provided in the casing 62 and the lock claw 72 is provided. The locking pawl 72 is horizontally swingable so that the tip of the locking pawl 72 protrudes and retracts from the side of the opening side of the retaining rod connecting part 67 when connected. Since the lock claw 72 protrudes from the opening of the locking rod joint 67, the locking rod 61 a in the locking rod junction 67 cannot pass through the opening of the locking rod junction 67, and the sliding door 1 is accidentally opened. Therefore, the sliding door 1 can be securely locked.

Also, the sliding opening / closing door 1
Is turned on when the hooking rod 61a of the
A closing confirmation switch 63 that activates 73 to put it in the locked state is provided on the casing 62, so that when the sliding door 1 is closed,
That is, when the locking rod 61a is fitted into the locking rod joint 67, the closing confirmation switch 63 is turned on, and the lock claw 72 is automatically locked by being hooked on the locking rod 61a. In addition, since the closing confirmation switch 63 is made to be able to move up and down the temporary elevator E when the closing confirmation switch 63 is in the "ON" state, unless the closing confirmation switch 63 is in the "ON" state, that is, the sliding door 1 must be closed properly. For example, since the temporary elevator E does not move, it is possible to prevent the slide opening / closing door 1 from being forgotten to be closed, and it is possible to further improve the effect of preventing the occurrence of a disaster caused by a drop of workers or materials from the temporary scaffold A of the temporary elevator E. I can do it.

Since the lock device main body 61 is provided with the closing confirmation switch 63 and the lock mechanism 64 in the casing 62, the size can be reduced, and the locking rod joint 67 can be formed. Is formed on one end surface of the casing 62 so as to extend in the up-down direction, so that when the hook rod 61a is fitted into the hook rod joint 67, both the vertically arranged closing confirmation switch 63 and the lock claw 72 are operated synchronously. Can be done.

Further, since the unlocking means for confirming the stop of the temporary elevator E and releasing the locked state is provided separately on the temporary scaffold A, the slide opening / closing door 1 cannot be opened unless the temporary elevator E is stopped. That is, since the sliding doors 1 on floors other than the stop floor cannot be opened, it is possible to prevent workers and materials from falling due to erroneous opening of the sliding doors 1.

Since the unlocking means is a stop confirmation switch 82 which is turned on when the temporary elevator E stops to release the locked state, the erroneous opening of the sliding door 1 can be easily prevented. Can be done.

Further, if the unlocking means is only the stop confirmation switch 82, the stop confirmation switch 82 may break down and the slide opening / closing door 1 may be erroneously opened, which may cause an accident. When the elevator stops, the stop confirmation switch 82 that is turned on and the stop confirmation switch 82
The lock state is released on condition that the state is "N". Since the release switch 100 is arranged on one side of the opening W and outside the temporary scaffold A, the slide is required if the two conditions are not satisfied. Since the door 1 cannot be opened, various accidents caused by erroneous opening can be completely prevented with the condition that a person must always be on the temporary elevator E side.

If the lock claw 72 swings greatly during locking, the locking claw 72 will force the locking rod 61 from within the locking rod joint 67.
a may come off, but since the stopper 76a for stopping the lock claw 72 at the locking position is provided on the casing 62 side, even if the drive unit 73 moves the lock claw 72 beyond the locking position, there is a potential Even if there is, the locking claw 72 can be reliably stopped at the locking position and locked, so that when the driving unit 73 is installed, it can be installed without determining the exact installation location.

The main components of the driving section 73 are replaced by solenoids 78.
And a connecting rod at the tip of an amateur 77 of the solenoid 78.
Connect the base end of 74 to the middle
The connecting rod 74 penetrates an L-shaped plate 79 fixed in the casing 62, and corresponds between the L-shaped plate 79 and a spring receiver 80 provided near the distal end of the connecting rod 74. Since the return spring 81 is externally arranged in the middle of the connecting rod 74, the armature 77 is retracted and unlocked by energizing the solenoid 78, and the armature 77 becomes free by shutting off the energization of the solenoid 78, The spring receiver 8 is restored by restoring the return spring 81 in the compressed state.
0, To advance and lock through the connecting rod 74, unlocking is possible only by turning on and off the solenoid 78 when the stop confirmation switch 82 or the closing confirmation switch 63 is turned on. Therefore, the lock can be unlocked by simple control means.

Further, since the elastic force of the return spring 81 decreases with time, there is a possibility that the lock claw 72 does not swing a required amount during locking. However, the connecting rod 74 is formed in a screw shape, and the spring receiver 80 is connected to the connecting rod.
Since the screw is fitted to the spring 74, the position of the spring receiver 80 with respect to the connecting rod 74 can be adjusted. If the spring receiver 80 is sequentially screwed in as the elastic force decreases over time, the return spring 81 will have a predetermined elasticity. Force can be maintained, so that the locking by the lock claw 72 can be ensured.

Also, the forcible unlocking means provided in the casing 62
Since the lock state can be released by swinging the lock claw 72 by 92, the lock device main body 61 is normally in the locked state,
Since the locked state of the lock device main body 61 can be released by the forced unlocking means 92 irrespective of the stop confirmation switch 82, the slide opening / closing door 1 is forcibly opened due to an emergency stop between the floors of the temporary elevator E, material loading, and the like. The practical effect is extremely large, for example, it is possible to cope with the case in which it must be performed.
