[0005]

However, in the conventional method of mounting the upper and lower divided boxes, since the upper box is lifted, the positioning when connecting the upper box and the boxes on both sides thereof is required. There is a problem that it is difficult and it takes a long time for the installation work. In addition, a sufficient space is required to lift the upper box, and there is a case where the upper and lower split boxes cannot be installed under a low ceiling.

The present invention has been made in view of the above circumstances, and has as its object the purpose of placing the upper box between the two boxes connected to both sides of the lower box. A mounting member provided with a protruding protrusion is detachably attached to the ceiling of the upper box, and the protrusion of the mounting member is guided to the upper and lower divided box side edges of the ceiling of both boxes. A guide member is detachably attached so that both guide members are parallel to each other,
The projecting portion of the mounting member is fitted to the two guide members, and the upper box is mounted between the two box bodies. The mounting member is mounted on the guide member until the projecting portion reaches a predetermined position in the guide direction of the guide member. By moving the upper box while guiding the protrusions of the upper box and connecting the upper box and both boxes, positioning of the upper box and the boxes on both sides is easy, and sufficient space is provided above. An object of the present invention is to provide a method of installing a vertically divided box body that can perform an installation operation in a short time even when there is no installation box, and an installation mechanism of the vertically divided box body used for the implementation.

[0007]

According to a first aspect of the present invention, there is provided a method of installing a vertically divided box body, wherein a lower box of a vertically divided box body in which an upper box is arranged on a lower box is installed at a required position. Projections are provided on both sides to protrude toward the two boxes to connect the boxes at the same height or higher than the upper and lower divided boxes and to mount the upper box between the two boxes. The detachable mounting member is detachably attached to the ceiling of the upper box, and a guide member for guiding the projecting portion of the above-described mounting member is provided at the edge of the ceiling of both boxes on the side of the upper and lower divided boxes. The members are detachably mounted so as to be parallel to each other, the protrusions of the mounting member are fitted to the two guide members, and the upper box is mounted between the two box bodies, and the protrusions are guided in the guide direction of the guide members. The upper box is moved while the projecting portion of the mounting member is guided by the guide member until the predetermined position of the upper box is reached, and the upper box and the two boxes are respectively connected. It is characterized in.

According to a second aspect of the present invention, there is provided a mechanism for mounting an upper and lower split box body on which a lower box is placed on an upper box, and a lower and upper split box on both sides of the lower box. A mechanism for connecting the boxes at the same height or higher than the body, and a mounting provided with a projecting portion protruding toward both the boxes to mount the upper box between the two boxes; A mechanism for detachably attaching the member to the ceiling portion of the upper box, and a guide member for guiding the projecting portion of the frame member to the upper and lower divided box body side edges of the ceiling portion of both the box members, the two guide members A mechanism for detachably attaching the mounting member so as to be parallel to each other, and a projecting portion of the mounting member fitted to the two guide members to mount the upper box between the two box members, and the projecting portion is guided in the guiding direction of the guide member. The upper box is moved while the guide member guides the projecting portion of the mounting member until the predetermined position is reached, and the upper box and the two boxes are respectively moved. Characterized in that it comprises a binding to mechanism.

[0009] A mounting mechanism for a vertically divided box body according to a third invention is characterized in that, in the second invention, a rotating member is rotatably attached to a lower portion of the protruding portion.

In the mounting mechanism for a vertically divided box body according to a fourth aspect of the present invention, in the second or third aspect, a stop portion for stopping the guide of the projecting portion is provided at a predetermined position in the longitudinal direction of the guide member. The upper box is moved while the guide member guides the projecting portion of the mounting member until the stopper reaches the stop portion.

A mounting mechanism for a vertically divided box body according to a fifth invention is characterized in that, in the fourth invention, a contact member with which the protruding portion contacts is provided as the stopper.

A mounting mechanism for a vertically divided box body according to a sixth invention is characterized in that, in the third invention, a concave portion into which a rotating member is fitted is provided as a stopper.

A mounting mechanism for a vertically divided box according to a seventh invention is characterized in that, in any of the second to sixth inventions, the vertically divided box and the box are distribution boards.

In the first, second and seventh inventions, two boxes having substantially the same height as the upper and lower divided boxes are connected to both sides of the lower box of the upper and lower divided boxes, respectively. A mounting member is removably attached to the ceiling of the box so that the protruding portion projects toward the two boxes, and a predetermined length is provided at the edge of the ceiling of the two boxes on the side of the vertically divided box. The guide members for guiding the projecting portions of the frame member are detachably attached so as to be parallel to each other. Then, the upper box is placed in front of the lower box, the upper box is lifted by a forklift truck or manually, and the protruding portions of the mounting members are fitted to the two guide members, and the upper box is mounted between the two boxes. I do. This allows the upper box to be mounted between the two boxes even when there is not enough space above.
