Description

[Detailed description of the invention] (Field of industrial application) This invention is an opening in a factory building in which a structure, such as a crane rail for a crane for loading and unloading steel materials, is installed between the indoor and outdoor areas through the opening of the building. This invention relates to a structure for closing an opening in a factory building.

(Prior art) Steel yards are usually installed outdoors, so when installing a crane for loading and unloading steel materials, an opening is created in the building and the crane rail is installed through this opening so that the crane body can move between indoor and outdoor steel yards. It allows you to run between the two. In such factory buildings, in order to improve the working environment inside the building,
When trying to air condition the inside of a building, it is necessary to close the openings to increase the air conditioning effect.

(Problem that the invention aims to solve) However, because the crane body travels through the opening and the crane rail is installed through the opening, it is not possible to securely install the door rail in the opening, and the opening The entire opening could not be closed with one door or shutter, and therefore the opening could not be sufficiently closed even when the crane was not in use. For this reason, even if air conditioning equipment was installed, its effectiveness was impaired and a suitable working environment could not be maintained.

(Means for solving the problem) In order to solve the above-mentioned problem, the present invention provides a closed structure for a factory building opening that penetrates the structure between indoors and outdoors through the opening, and an opening is opened at the bottom of the structure. A fixed rail is installed horizontally on one side of the opening, a slide rail is supported within the fixed rail and can be slid across the entire width of the opening, and a slide rail is provided on the opposite side that can be engaged with the rail receiver. A sliding door is provided between the door and the lower rail laid on the floor surface so that the lower part of the opening can be closed.
The structure is provided with a shutter so that the upper part of the opening can be closed.

(Work) With the above configuration, if you want to close the opening, first pull out the slide rail and install it in the opening, then move the slide door between this slide rail and the lower rail. The opening below the structure can be closed, and the opening above the structure can be closed by lowering the shutter. On the other hand, when it becomes necessary to open the opening, all you have to do is raise the shutter and move the slide door and slide rail to the side to store it. There will be no obstacles in the way, and you will be able to secure the space you need.

(Example) 1 is a factory building in which an opening 2 is provided. A crane rail 3 is installed through this opening 2, and a crane main body 4 can reciprocate between an outdoor steel material yard 5 and an interior 6 of the factory building 1 to carry steel materials in and out.

Reference numeral 7 denotes a fixed rail fixed horizontally to the building side wall 1a on one side of the opening 2 at the lower part of the crane rail 3, and a pair of left and right fixed rail bodies 8a, 8b and a bracket are arranged so as to have a U-shaped cross section with an opening at the bottom. The brackets 9a, 9b are composed of a pair of slide rail receiving rollers 11a, 11b and a connecting member 10 provided at several locations at appropriate intervals in the length direction of the brackets 9a, 9b. 10 has a floating prevention rail 12 provided along its length.

A slide rail 13 is supported within the fixed rail 7 and has a length that allows it to slide over the entire width of the opening 2. The slide rail 13 is supported by the slide rail receiving rollers 11a and 11b of the fixed rail 7, and the opposing sides serve as door roller guides. It is composed of a pair of rail bodies 15a and 15b formed as surfaces 14a and 14b, and a floating prevention roller 16 that engages with the floating prevention rail 12 of the fixed rail 7.

17 is a slide rail receiver provided on the opposite side of the opening 2 and can be engaged with the tip of the slide rail 13, and 18 is a lower rail laid on the floor surface of the opening 2.

Reference numeral 19 denotes a plurality of sliding doors provided between the slide rail 13 and the lower rail 18, each of which has a rail main body 15 of the slide rail 13 at the top.

22 is a shutter installed at the top of the crane rail 3, and when lowered, the slide rail 13
It is installed so that the upper opening can be closed. The shutter 22 is shaped so as to be lowered between the crane rails 3 on both sides so as not to interfere with them.

Next, the effects of the above embodiment will be explained.

When using the crane, open opening 2,
A crane body 4 is run on a rail 3 and reciprocated between a steel yard 5 and a building 6 to carry in and take out necessary steel materials.

On the other hand, when closing the opening 2, first move the fixed rail 7 from the state shown in FIG. 6a to the state shown in FIG. 6b.
Pull out the slide rail 13 stored inside, extend it to the opposite side of the opening 2, and attach it to the rail receiver 1.
7. Then, as shown in FIG. 6c, the slide door 19 is sequentially moved to close the lower part of the crane rail 3. Thereafter, the upper part of the crane 3 is closed off by lowering the shutter 22 as shown in FIG. 6d. In this way, the opening 2 can be completely closed when the crane is not in use.

In the above embodiment, the case of a crane for carrying in and out of steel materials has been described as an example, but the present invention is not limited thereto, and although a plurality of sliding doors are illustrated, it may be one. Further, the fixed rail may be provided either inside or outside the side wall of the building, and the slide rail and sliding door may be drawn out and stored either manually or electrically.

(Effects) As is clear from the above explanation, according to the present invention, even if a structure such as a crane rail penetrates an opening in a factory building, this opening can be sufficiently blocked if necessary. Even when air-conditioning the inside of a building, the temperature can be maintained at an appropriate temperature without impairing the air-conditioning effect.
