Description

  The present invention relates to a stage for getting on and off a construction elevator. More specifically, the present invention is installed on a ground floor for a construction elevator that lifts personnel and materials to an upper floor when building a tall building. Related to boarding / exiting stage.

  For example, when building a high-rise building, it is well known that an elevator for construction is provided on the upper floor to carry personnel and materials such as workers. A general construction elevator includes a cage that is guided by an elevator post that is erected while supporting an outer wall of a building, and a person is loaded on the cage or is loaded and unloaded with materials. Further, the cage lifting mechanism in such a construction elevator generally includes an electric motor installed on the lower surface of the floor of the cage, and a rack in which a gear attached to the rotating shaft of the electric motor is attached to the elevator post. The cage is raised and lowered by rotating a gear engaged with the rack by an electric motor.

  Therefore, on the lower surface of the cage floor of the construction elevator, there are installed drive mechanisms such as an electric motor and a gear that is rotated by its rotating shaft, and a reduction gear box that decelerates the rotation of the electric motor and transmits it to the gear. Therefore, the stop position of the cage on the ground floor is often set such that the floor surface of the cage is located at a height of about 1000 to 1500 mm from the ground. Therefore, in such a construction elevator, a boarding stage, that is, a platform-like deck is temporarily installed in front of the cage boarding / alighting section at the ground floor stop position so that personnel can get on and off the cage on the ground floor.

  Workers who enter the cage of the construction elevator on the ground floor use the 4-7 steps installed on the boarding stage to climb onto the boarding stage, board the cage from this boarding stage, or A person who gets on the cage and descends to the ground floor from when the cage stops on the ground floor, descends from the boarding area to the boarding stage and further descends to the ground.

In such an elevator for construction, there is no problem when personnel get on and off the cage, but when carrying materials to the cage and transporting it to the upper floor, the material transport vehicle is stopped near the boarding stage, and its loading platform Therefore, it was necessary for the workers to manually carry them to the boarding stage and transfer them to the cage. In addition, when unloading materials from the upper floor, the procedure was reversed, requiring manual work to unload the cage from the loading / unloading stage and then load it onto the vehicle. Accordingly, an elevator for construction work as disclosed in Patent Document 1 has been developed in order to facilitate loading and unloading of such materials into a cage. In the elevator for construction work disclosed in Patent Literature 1, a small crane is installed in a cage, and the crane is lifted and lowered together with the cage. According to this elevator for construction work, materials are lifted from a loading platform of a material transport vehicle by a crane installed in the cage to a cage stopped on the ground floor and transferred to the cage or vice versa. It is possible to easily transfer materials to the loading platform of the vehicle.

  However, in the elevator for construction work disclosed in Patent Document 1, since the crane is integrally installed in the cage, the weight of the cage itself becomes heavy. Therefore, an electric motor having a large driving torque, a highly durable gear, Not only is a rack required, but the cage structure is also complicated. For this reason, there is an economic problem that temporary construction of an elevator for construction work is very expensive, and maintenance costs after temporary construction, that is, power consumption is large, and these costs increase the construction cost of the building. It was.

  An object of the present invention is to solve such a conventional problem. When personnel get on and off the cage on the ground floor, the boarding stage is used as usual, and the material is placed on the cage and fried. When unloading, a part of the boarding stage located in front of the boarding / alighting part of the cage moved to the side so that a material transport vehicle such as a fork wrist can directly get close to the cage. It is to provide a stage for getting on and off the elevator for construction.

  The present invention is directed to a front position facing a boarding / alighting portion of the cage of a construction elevator in which the ground floor stop position of the elevator that can be raised and lowered is set to a predetermined height from the ground surface, and in a direction of getting into the cage from the front position. A boarding / alighting stage installed in a substantially orthogonal lateral direction and between a first lateral position adjacent to the front position, characterized in that the boarding stage is located at the front position And a movable deck that can reciprocate between the first side position, and when a person gets in and out of the cage of the construction elevator on the ground floor, the movable deck is The movable deck moves from the lateral position to the front position and is used for getting on and off the cage to and from the cage. When loading and unloading materials on the ground floor from the cage, the movable deck is moved to the first lateral position. Move to material truck There is that was accessible to the landing portion of the cage.

  In one example of the embodiment of the construction elevator boarding / exiting stage according to the present invention, a guide member that supports the movable deck so as to reciprocate between the front position and the first side position is provided on the ground floor.

  In another example of the embodiment of the construction elevator boarding / exiting stage according to the present invention, the drive mechanism unit includes a rack attached to the movable deck, a motor installed on the gantry, and an output shaft of the motor. A gear that receives rotational force and meshes with the rack.

  According to the stage for getting on and off the construction elevator according to the present invention, when a person gets on and off the cage, the movable deck is moved to a front position facing the boarding and getting off part of the cage, and when the material is put on and off the cage, the movable deck is moved. Can be moved to the first lateral position to create a space in which the forklift can enter the front position of the cage. Therefore, the material can be directly placed on or lowered from the cage with a forklift, and the work time for loading or unloading the load such as the material on the cage can be shortened or the labor can be reduced. Moreover, since it is not necessary to additionally install any device (for example, a crane or the like) in the cage in order to obtain such an effect, a conventional construction elevator can be used. As a result, it is possible to suppress the construction elevator temporary cost and the maintenance cost after the temporary construction.

  Further, according to the stage for getting on and off the construction elevator according to the present invention, a guide member, for example, a guide rail, is installed between the front position and the first side position in the vicinity of the cage which is the stop position on the ground floor. Since the movable deck is supported by the guide member so as to be able to reciprocate between the front position and the first lateral position, the guide member serves as a stop bar so that the material transport vehicle such as a forklift is in a space state. It is possible to prevent the cage from accidentally colliding with the cage when entering the front position and approaching the cage.

  Furthermore, according to the stage for boarding / alighting of the construction elevator according to the present invention, the gantry for supporting the movable deck is installed at the first lateral position in the lateral direction adjacent to the front position facing the boarding / alighting portion of the cage, and the front position A deck for boarding / exiting personnel is installed at the second side position opposite to the first side position with the front of the movable deck being moved to the front position. Since it is supported by the end of the movable deck, the movable deck can be safely supported at the front position.

  Furthermore, according to the boarding / alighting stage of the construction elevator according to the present invention, the personnel boarding / awaiting deck includes a standing position rising from the upper surface of the boarding / alighting deck and a storage position below the boarding deck for personnel boarding / alighting. When the movable deck is moved to the first side position, the protective fence that moves up and down is installed across the lateral direction facing the front position from the second side position. It is possible to prevent personnel from entering the front position when the cage is away from the ground floor and to ensure safety to the personnel.

Temporary or dismantled.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment shown in the drawings of a construction elevator boarding / exiting stage according to the present invention will be described in more detail. 1 to 3 show a boarding stage (hereinafter referred to as boarding stage) 10 for a construction elevator according to an embodiment of the present invention. 1 to 3 are a plan view, a front view, and a side view, respectively, of a boarding / alighting stage 10 according to the same embodiment. The construction elevator 30 shown in FIGS. 1 to 3 is well-known, and its detailed structure is omitted. Basically, elevator posts 31 are erected at intervals, and a cage is provided between them. 32 is supported so that raising / lowering is possible. Also, normally, racks (not shown) extending in the height direction are attached to both elevator posts 31, and gears (not shown) installed on the lower surface of the cage 32 are meshed with the racks. The cage 32 is configured to move up and down along the elevator post 31 by being directly rotated by the rotating shaft of the electric motor or by being rotated through a speed reducer.

  In such a construction elevator 30, as described above, since an electric motor for raising and lowering, a speed reduction mechanism, and the like are attached to the lower surface of the cage 32, the cage 32 is stopped at the stop position of the cage 32 on the ground floor. The floor is G. L. To a predetermined height. Therefore, in such a construction elevator 30, the boarding stage 10 faces the boarding / alighting portion 32 a of the cage 32 so that personnel can get on and off the cage 32 on the ground floor, and the front position 11 is sandwiched between The two elevator posts 31 are temporarily installed over both side positions. For convenience, the arrangement direction of the two elevator posts 31 is indicated as “lateral direction” by arrows X in FIGS. 1 and 2, and both lateral positions in the lateral direction X across the front position 11 are first lateral positions. 12a and the second lateral position 12b. A pedestal 13 made of a steel material is installed at a first side position 12a located on the right side of the front position 11 when viewed in FIGS.

  The gantry 13 includes two guide rails 13a and 13b arranged at intervals in the direction of entry into the cage 32, and a plurality of columns 13c that support the guide rails 13a and 13b. Here, the “entry direction to the cage 32” is a direction that is substantially orthogonal to the lateral direction X as seen in FIGS. 1 and 3 and gets on and off from the front position 11 toward the cage 32, as shown in FIGS. 4 and indicated by an arrow Y in FIG. Each of the guide rails 13a and 13b is made of a groove-type steel material whose end surface is U-shaped. The groove sides of these steel materials are opposed to each other, and the upper surface of each steel material is positioned in substantially the same plane as the floor surface of the cage 32. Is installed. In this embodiment, each of the guide rails 13a and 13b is made of a U-shaped groove-type steel material. However, the present invention is not limited to this type of steel material. For example, the H steel whose end surface is H-shaped. Can also be used. Of the two guide rails 13a and 13b, the guide rail 13a arranged close to the cage 32 extends between the front position 11 and the first side position 12a, and the other guide rails 13b 1 is disposed only at one side position 12a. As shown in FIG. 1, the width dimension in the lateral direction X at the first lateral position 12 a is approximately twice the width dimension L in the lateral direction X at the front position 11.

  A movable deck 14 is disposed between the two guide rails 13 a and 13 b constituting the gantry 13. As shown in FIG. 4, the movable deck 14 includes a deck body 15 including a deck portion 15a and side wall portions 15b provided so as to hang down from both side edges on the Y direction side of the deck portion 15a. Three support shafts 16 are attached to the respective side wall portions 15b of the main body 15 so as to protrude outwardly at predetermined intervals in the lateral direction X, and rollers 17 are rotatable on the respective support shafts 16 respectively. It is supported by. The rollers 17 supported by the respective side wall portions 15b are arranged in the grooves of the grooved steel material constituting the guide rails 13a and 13b, so that the movable deck 14 can move in the lateral direction X along the guide rails 13a and 13b. Can be moved to. In this movable deck 14, the surface of the deck portion 15a is positioned in the same plane as the upper surfaces of the guide rails 13a and 13b by adjusting the mounting position of the support shaft 16 with respect to the side wall portion 15b. Is located on the same plane as the floor surface of the cage 32 of the construction elevator 30 stopped at a predetermined position on the ground floor. The dimension of the deck body 15 in the lateral direction X is 2L, which is the same as the lateral dimension of the first side position 12a. Accordingly, when the movable deck 14 is moved to the first side position 12a, the movable deck 14 is completely accommodated in the first side position 12a.

  Here, the attachment positions of a total of six rollers 17 that are respectively supported by three side walls 15b of the deck body 15 will be described. Since the width dimension of the deck body 15 is twice the width dimension L of the front position 11, when the movable deck 14 is moved to the front position 11, the deck body 15 has a front half in the width direction X (front end on the front position side). Only the width dimension L) extends from the first lateral position 12a to the front position 11, and the rear half of the deck body 15 (the width dimension is also L) remains at the first lateral position 12a. . One roller 17 is attached to each side wall portion 15b on the front end side in the front half of the deck main body 15, and two rollers 17 are attached to each side wall portion 15b of the latter half portion with an interval in the lateral direction X. ing. Therefore, when the movable deck 14 moves and the front half of the deck main body 15 moves to the front position 11, only one roller 17 attached to the front end of the front half of the deck main body 15 has one guide rail. The other rollers 17 are only in the running grooves of the guide rails 13a and 13b and support the deck main body 15 only by coming off from 13b. As a result, at the front position 11, the front half of the deck body 15 can be supported by only one guide rail 13a. However, when the front half of the deck main body 15 is moved to the front position 11 due to a case where a larger load is applied due to a person getting on the front half of the deck main body 15, the front end of the deck main body 15 is the personnel described later. It is supported by connecting to the boarding / alighting deck. This support structure will be described later.

  In the deck main body 15, reinforcing ribs 15c are provided on the back surface of the deck portion 15a at a predetermined interval in the lateral direction X, and the end portions of the reinforcing ribs 15c are coupled to the side wall portions 15b. A driving force that reciprocates between the front position 11 and the first side position 12a is applied to the movable deck 14 by the drive mechanism section 18. The drive mechanism unit 18 includes a rack 18a attached to the deck body 15 of the movable deck 14, a gear 18b that meshes with the rack 18a, and an electric motor 18c that rotates the gear 18b. The rack 18 a is attached to the reinforcing rib 15 c of the deck body 15 and has a strip shape extending in the lateral direction X. The electric motor 18c is mounted on a horizontal beam 13d supported by a column 13a constituting the gantry 13, and a gear 18b is attached to an output shaft thereof so as to mesh with the rack 18a. Thus, when the electric motor 18c is driven, the rotating gear 18b applies a moving force to the meshed rack 18a, so that the movable deck 14 moves in the lateral direction X.

  As described above, when the movable deck 14 is moved from the first side position 12a and the front half thereof is moved to the front position 11, it is attached to the front end side of the deck body 15 and moves in the groove of the guide rail 13b. One roller 17 comes off the guide rail 13b. At that time, a structure for supporting the front end portion of the deck main body 15 together with the personnel boarding / alighting deck will be described. Personnel boarding / alighting deck 19 is installed at second side position 12b opposite to first side position 12a with front position 11 interposed therebetween. This personnel getting on / off waiting deck 19 is for transferring personnel to the movable deck 15 that has moved to the front position 11 and getting on the cage 32 of the construction elevator 30. 2 and 5, two groove steel members 19a extending in the transverse direction X are arranged side by side in the Y direction, these groove steel members 19a are supported by a plurality of columns 19b, and the iron plate 19c is grooved. It is mounted so as to span the steel material 19a. As shown in FIG. 5, a step portion 20 is formed at an end portion of the personnel boarding / awaiting deck 19 facing the front position 11. That is, the stepped portion 20 is configured by notching the upper part of the tip of each grooved steel material 19a into an L shape and bridging the load receiving rod 20a between the grooved steel materials 19a at the notched lower part.

  On the other hand, a stepped portion 21 is also formed at the front end portion of the deck body 15 facing the front position 11. Specifically, as shown in FIG. 6 in which the front end portion of the deck body 15 is enlarged, the lower side of the front end portion is notched into an inverted L shape, and the load between the side wall portions 15b in the upper portion of the notched portion is cut. The receiving bar 21a is fixed to form the stepped portion 21. The sizes and shapes of the step portions 20 and 21 in both decks 14 and 19 are such that the step portions 20 and 21 are closely meshed with each other when the front end portion of the deck body 15 abuts against the end portion of the passenger boarding / awaiting deck 19. Designed to overlap in a stacked state. Accordingly, at this time, the step portion 21 at the front end portion of the deck main body 15 is in a state of riding on the step portion 20 at the end portion of the personnel getting on / off waiting deck 19, so the front half of the deck main body 15 moved to the front position 11 is Since the front end portion and the edge portion along the cage 32 are supported by the end portion of the person getting on / off waiting deck 19 and the guide rail 13a, respectively, even if a person gets on the front half of the movable deck 14 moved to the front position 11, it is strong. Will not cause any problems.

  A stairway 22 for ascending / descending the deck 19 from the ground is attached to the personnel boarding / awaiting deck 19 at a lateral end opposite to the front position 11. In addition, a slit 23 extending in the Y direction is formed in the iron plate 19c forming the surface of the passenger boarding / awaiting deck 19, and an elevating type protective fence 24 is installed at a storage position immediately below the slit 23. The protective fence 24 enters and exits from the slit 23 by a predetermined operation, and enables or prevents entry of the person who has risen from the stairs 22 to the personnel entry / exit standby deck 19 to the front position 11. Safety is achieved. 1, 2, and 4, reference numeral 25 indicates a protective fence installed on one side in the Y direction (opposite to the construction elevator 30) on the upper surface of the deck main body 15. These show the protection fence installed in the upper surface of one guide rail 13b located in the 1st side position 12a in the mount frame 13. FIG. These protective fences 25 and 26 are arranged in a row in the lateral direction X as seen from the front side as shown in FIG. 2 when the movable deck 14 moves in the direction of the front position 11 as shown in FIGS. It is installed to line up. Further, a protective fence 27 is fixedly erected on one side of the upper surface of the iron board 19c of the passenger boarding / alighting deck 19 in the Y direction (the side opposite to the construction elevator 30).

  1 to 3, reference numeral 28 indicates an opening / closing door 28 including an accordion-type shutter 28 c supported by support portions 28 a and 28 b fixed to the elevator post 31 of the construction elevator 30. . When the cage 32 of the construction elevator 30 is away from the ground floor, the open / close door 28 covers the construction elevator 30 by spreading the shutter 28c as shown by phantom lines in FIG. 10 to prevent personnel from accidentally entering the cage lift path. When the cage 32 descends to the ground floor and stops, and when a person gets on or off the boarding deck 10, the shutter 28c is folded to one side to open the boarding / unloading portion 32a of the cage 32 as shown by a solid line in FIG. To do.

  Next, the operation of the boarding / alighting deck 10 according to this embodiment will be described. 1 to 3 show a state of the boarding / alighting stage 10 when the cage 32 of the construction elevator 30 is away from the ground floor. Usually, since the construction elevator 30 is often used for transporting personnel, the movable deck 14 is moved in the direction of the front position 11, and therefore the front half of the deck body 15 in the movable deck 14 is located at the front position. 11 is. Since the cage 32 of the construction elevator 30 is away from the ground floor, the shutter 28c of the open / close door 28 is in a closed state, and the lifting protection fence 24 of the passenger entry / exit standby deck 19 extends from the slit 23 to the iron plate 19c. It stands up and prevents a person from the boarding / leaving deck 19 from entering the movable deck 14 at the front position 11. When the cage 32 of the construction elevator 30 descends from the upper floor and stops at a predetermined position on the ground floor, a security worker on the passenger boarding / departure waiting deck 19 opens the shutter 28c of the door 28 and gets on and off the cage 32. Open 32a. When the shutter 28c is folded to one side and the boarding / alighting part 32a of the cage 32 is opened, folding of the shutter 28c is detected by a sensor (not shown), and the elevating type protective fence 24 provided in the personnel boarding / receiving standby deck 19 is provided. Is lowered to the lower storage position via the slit 23 based on the detection signal. As a result, the personnel riding on the cage 32 descend from the boarding / alighting part 32 a to the movable deck 14 and further descend from the stairs 22 via the personnel boarding / alighting machine deck 19 to the ground. In addition, the person waiting for getting on and off waiting in front of the protective fence 24 enters the movable deck 14 and transfers to the cage 32. When the cage 32 of the construction elevator 30 on which a person is placed rises, the security worker closes the shutter 28c of the door 28. When the shutter 28c is closed, a sensor (not shown) detects this, and based on the detection signal, the lifting / lowering protection fence 24 of the passenger boarding / awaiting deck 19 is raised, and from the personnel boarding / alighting deck 19 to the movable deck 14. The entry of other personnel is prevented.

  Next, the case where a material is placed on the cage 32 of the construction elevator 30 and raised to the upper floor will be described. When the cage 32 stops at a predetermined position on the ground floor, the security guard switches off the open / close door detection sensor and then opens the shutter 28c. And the drive switch of the electric motor 18c which comprises the drive mechanism part 18 of the movable deck 14 is pushed, this is driven, and the movable deck 14 is moved toward the 1st side position 12a in the horizontal direction X. When the movable deck 14 is detected by a sensor (not shown) installed at its rear end opposite to the front side of the gantry 13 or comes into contact with a limit switch (not shown), The drive of the electric motor 18c is stopped, and the movement of the movable deck 14 is stopped. As a result, the front half of the movable deck 14 retreats from the front position 11 and moves to the first side position 12a, and the front position 11 has a space where the forklift 35 and the like can travel on the ground and approach the cage 32. it can.

  As a result, the forklift 35 on which the material 36 is placed on the fork enters the frontal position 11 in the space state and approaches the cage 32, and the fork is directly inserted into the cage 32 to place the material 36 on the floor surface of the cage 32. take down. One of the guide rails 13a and 13b constituting the gantry 13 is located on the cage 32 side, but the forklift 35 stops in front of the guide rail 13a and raises the fork. Thus, if the material is loaded and unloaded from the cage 32, the guide rail 13a does not interfere with the work. Further, since the upper surface of the guide rail 13a is substantially the same as the floor surface of the cage 32, the fork of the forklift 35 cannot be lowered below that. A suitable cradle (not shown) for receiving is placed so that the fork can be loaded on the cage 32 without being lowered below the guide rail 13a. The protective protection fences 26, 25, and 27 erected on the guide rail 13 b of the pedestal 13, the upper surface of the movable deck 14, and the upper surface of the passenger boarding / alighting deck 19 do not have to be in their positions, Depending on the size of the material to be loaded and unloaded in the cage 32, it is also preferable to reduce the number or make it removable.

  Further, as a result of positioning one guide rail 13a on the side of the cage 32 in the Y direction of the front position 11, when the forklift 35 enters the front position 11 in the space state and approaches the cage 32, the cage 32 is mistaken. It functions as a stop bar that prevents it from colliding with. Simply, when the entire boarding stage 10 at the front position 11 is moved to the side to bring the front position 11 into a space state, the forklift 35 approaches the cage 32 of the construction elevator 30 and collides with the cage 32. If the lifting / lowering function is hindered, it will take a lot of time and money to repair it, resulting in construction delays. However, by extending one of the two guide rails 13a and 13b for guiding the movable deck 14 on the side close to the cage 32 from the first side position 12a to the front position 11, the guide rail 13a In addition to supporting the movable deck 14, it also serves as a stop bar that prevents the forklift 35 from accidentally colliding with the cage 32. In this embodiment, the forklift 35 is used to transfer the material 36 to the cage 32 as shown in FIGS. 3, 7, and 8. However, the present invention is not limited to the forklift, for example, A cargo vehicle such as a truck can be moved back to bring the cargo bed closer to the cage 32, and loads and materials can be transferred from the cargo bed to the cage 32.

  In this way, after placing materials or the like on the cage 32 of the construction elevator 30, if there is a margin in weight, the security staff moves the movable deck 14 to the front position 11 side and sets the front position 11 in the front half. It is also possible to bring a person who is fully closed and waiting on the personnel boarding / awaiting deck 19 into the cage 32.

  According to the stage 10 for getting on and off the construction elevator according to the above-described embodiment, when a person gets on or off the cage 32, the movable deck 14 is moved to the front position 11 facing the boarding / alighting portion 32a of the cage 32, and the material 36 Since the movable deck 14 can be moved to the first side position 12a and a forklift or the like can be made to enter the front position 11 of the cage 32 when the load is placed on or lowered from the cage 32, the material 36 can be made. Can be directly mounted on or lowered from the cage 32 by a forklift 35 or the like. As a result, it is possible to shorten the work time for loading and unloading loads such as materials on the cage 32 and to reduce the work effort. In addition, in order to obtain such an effect, it is not necessary to additionally install any device (for example, a crane or the like) in the cage 32. Therefore, a conventional construction elevator can be used. It is possible to reduce the temporary construction elevator costs and the maintenance costs after the temporary construction.

Since the movable deck 14 is supported by the guide rail 13a so as to be able to reciprocate between the front position 11 and the first side position 12a, the guide rail 13a serves as a stop bar and is used as a forklift. When 35 enters the front position 11 in the space state and approaches the cage 32, it can be prevented from accidentally colliding with the cage 32.

  Furthermore, according to the boarding / alighting stage 10 for the construction elevator, the gantry 13 that supports the movable deck 14 at the first lateral position 12a in the lateral direction X adjacent to the front position 11 facing the boarding / alighting portion 32a of the cage 32. And a deck 19 for getting on and off the person is installed at the second side position 12b opposite to the first side position 12a across the front position 12a, and the movable deck 14 moves to the front position 11. Since the front end of the movable deck 14 is supported by the end of the passenger boarding / alighting deck 19, the movable deck 14 can be safely supported at the front position 11. In the above-described embodiment, when the movable deck 14 has moved to the front position 11, the front end thereof is supported by the end of the passenger boarding / awaiting deck 19. Although the engagement structure that the portion 21 rides on the stepped portion 20 formed at the end of the personnel boarding / awaiting deck 19 is adopted, the present invention is not limited to such an engagement structure between the stepped portions. A recess may be formed on the end surface of the boarding / awaiting deck 19, and the leading end of the movable deck 14 may be fitted into the end surface recess of the person boarding / awaiting deck 19.

  Furthermore, according to the boarding / alighting stage 10 for the construction elevator, the crew boarding / standby deck 19 includes a standing position rising from the upper surface of the boarding / alighting deck 19 and a lower side of the boarding deck 19 for boarding / exiting the crew. Since the protective fence 24 that moves up and down between the storage position and the lateral position X from the second lateral position 12b to the front position is installed, the movable deck 14 is moved to the first lateral position 12a. It is possible to prevent the personnel from entering the front position 11 when moving and to ensure safety to the personnel. Moreover, according to the stage 10 for boarding / exiting to this construction elevator, since the drive mechanism unit 18 for moving the movable deck 14 is composed of the rack 18a and the electric motor 18c, the structure is simple, so The stage 10 can be easily temporarily set up and dismantled.
