The construction door 1 is a bellows-shaped door that separates the elevator side and the stage side of each floor at a construction site such as a building. Therefore, the construction door 1 is carried in and installed at the start of construction, and dismantled and removed when the construction is completed.

The construction door 1 in the first embodiment is in a state in which all the paired doors 12 are folded to the left end by pulling the support column 13 at the right end of FIG. 1 (a) in the left direction (-X direction) from the closed state ( The construction door 1 can be opened). Then, people and objects can enter and exit the elevator in the open state (folded state) of the construction door 1, and the elevator moves up and down in the closed state, so that the safety of people and objects can be ensured. The width direction (X direction) of the construction door 1 is about 5 to 7 m, and the height direction (Z direction) is about 2 to 3 m. Further, the dimension in the Y direction when the construction door 1 is folded is about 40 to 50 cm. These dimensions can be changed as appropriate depending on the size of the elevator for construction work and the like. When the construction door 1 is open (folded), the construction door 1 is folded toward the stage so as not to come into contact with the elevator.

As shown in FIG. 2, the construction door 1 is installed on the first upper rail 6 and the second upper rail 6'that extend linearly in the X direction at the upper part and extend horizontally and in parallel at the same height. It is provided with a suspended support column 13. The construction door 1 has a plurality of columns 13, and is rotatably supported by inserting the toggle pins of the pair of doors 12 into the toggle pin receiving portions 8 provided on each column 13. Further, as shown in FIG. 3, the pair of doors 12 can be opened and closed in a bellows shape by supporting the two doors 14 so as to be openable and closable by a plurality of hinges 11. As shown in FIG. 3, the door 14 has a door frame whose main raw material is an aluminum vertical frame 2 and a horizontal frame 3 (in the first embodiment, two vertical frames 2 and 4 horizontal frames). Door frame consisting of frame 3). A punching metal 4 is held in each of the vertical frame 2 and the horizontal frame 3 via a spacer rubber (not shown). Since the door 14 is made of the punching metal 4, it is possible to prevent the door 14 from being greatly agitated by the wind caused by the ascent and descent of the elevator.

As shown in FIG. 2, the first upper rail 6 suspends the first suspension portion 22, and the second upper rail 6'suspends the second suspension portion 22'. The first hanging portion 22 has a first hanger roller 25, and the first hanger roller 25 is rotatably suspended on the first upper rail 6.

Further, the first hanging portion 22 and the second hanging portion 22'are bolted by the connecting rod 26 and are connected to each other by a distance A and integrated.

The support column 13 can smoothly move in the X direction by being rotatably suspended on the first upper rail 6 and the second upper rail 6'by the first hanging portion 22 and the second hanging portion 22'. Then, the support column 13 smoothly moves in the X direction, and each pair of doors 12 is opened or folded, so that the construction door 1 is smoothly closed or opened.

If the column 13 is suspended by only one upper rail, the center of gravity of the door 14 is located away from the column 13, so the column 13 rotates about the Z direction and the hanger roller is on the rail. There is a possibility that the support column 13 cannot be moved smoothly due to the rampage. However, by suspending the support column 13 on the two rails of the first upper rail 6 and the second upper rail 6', the hanger roller can be prevented from running wild on the rail and the support column 13 can be smoothly moved.

Further, in the first embodiment, in order to prevent the hanger roller from running wild on the rail due to the rotation of the support column 13, the position where the second hanging portion 22'is provided is devised. That is, as shown in FIG. 4, the second hanging portion 22'is located on the hinge side (Y direction side of the center of gravity position P) of the center of gravity P of the door 14 when the pair of doors 12 is folded. Is provided with a distance A from the first hanging portion 22.

As a result, the door 14 can be prevented from falling to the support column 13 side (-Y side), and the construction door 1 can be smoothly opened and closed. Further, the distance between the first upper rail 6 and the second upper rail 6'is also provided in parallel with the same distance A, so that the first hanger roller 25 and the second hanger roller 25'roll smoothly. The support column 13 can be moved by moving.

As shown in FIG. 2, both ends of the first upper rail 6 and the second upper rail 6'in the first embodiment are open.
