Description

[Detailed description of the invention] [Industrial application field] The invention is applicable to lighting equipment, fire detectors, cables for the electrical equipment, and partitions installed outside the filter in a laminar flow clean room. The present invention relates to a filter mounting frame that is easy to install, and allows for the installation of each device in a new layout even if the above-mentioned devices are removed due to a layout change.

[Background of the idea] In recent years, many high-performance clean rooms have been constructed, mainly in the semiconductor industry. As particle management becomes more sophisticated in future clean rooms, the important issues will be applicability, ease of construction, and economy. Furthermore, to put this more specifically, when the interior of a clean room is frequently rearranged due to advances in production equipment or layout changes, the filter mounting frame is suspended and fixed from the ceiling, so there is no need to replace it. A filter mounting frame that can be used as is and reattached to lighting equipment, fire detectors, cables for the above-mentioned electrical equipment, partitions, etc. is required from the viewpoints of applicability, workability, and economy. There is.

[Problems to be solved by conventional technology and ideas] Conventional filter mounting frames in full-surface laminar flow clean rooms use rectangular steel or concave steel, and are mainly focused on installing only filters. Accessory equipment such as electric lights and ballasts are simply attached to the underside of the frame, or a new space is created for the accessory equipment and the accessory equipment is installed in this space.

For example, in the one shown in FIG. 4, a mounting frame 22 using rectangular steel 21 is suspended and fixed from the ceiling with hanging bolts 23, and a filter 24 is mounted and fixed on the mounting frame 22. In order to mount the electric light 25 on the lower surface of the mounting frame 22 using this rectangular steel 21, as shown in the figure, a casing 26 containing attached equipment such as a ballast is mounted on the lower surface of the mounting frame 22, and the lower surface of the casing 26 Electric light 25 was installed. However, as shown in Fig. 4, the electric light 25
When the casing 26 is installed, there is a problem that the connection cable 27 is exposed when viewed from the side as shown in FIG. Another problem was that the mounting screw holes remained as they were, making them unsightly.

In addition, the one shown in FIG. 6 uses a concave steel 28 wider than the square steel 21 in the required places, and the mounting frame 22a is formed using the same square steel 21 as in FIG. 4 in other parts. Concave steel 28
Ancillary equipment 29 such as a ballast is housed and attached inside, the lower surface of the recessed steel 28 is shielded with a cover plate 30, and an electric light 25 is attached to the lower surface of the cover plate 30.

However, as shown in Fig. 6, the attached equipment 2
If 9 is stored and installed, commercially available accessory equipment 29
can be stored as is in the recessed steel 28 of the mounting frame 22a, and connection cables etc. can also be stored inside, but when changing the layout, the attached equipment 2
9 could not be transferred to the rectangular steel 21 without an opening.

Furthermore, in the case shown in FIG. 7, as in the case of FIG. 4, a recessed steel for mounting 31 having a storage space for the connection cable 27 is attached to the lower surface of the mounting frame 22b using the rectangular steel 21, and the mounting A casing 26 housing accessory equipment was attached to the lower surface of the recessed steel 31, and an electric light 25 was attached to the lower surface of the casing 26.

However, when the casing 26 is attached as shown in FIG. 7, the connection cable 27 is not exposed and is not unsightly, but the height of the attachment frame 22b increases, which is inconvenient when attaching the filter 24. Furthermore, when the casing 26 is removed and relocated due to a layout change and the recessed steel 31 for mounting is removed, the screw hole in which the recessed steel 31 was attached remains on the lower surface of the mounting frame 22b and is unsightly. It was hot.

Furthermore, equipment other than the above-mentioned ballasts and other accessory equipment, such as fire detectors and speakers that detect smoke and heat,
TV cameras require connection cables, so
It was attached to a concave steel 28 portion of a mounting frame 22a using concave steel 28 shown in FIG.

Therefore, when the fire detector, speaker, and TV camera were relocated to the rear section of the modified steel section 21, the connection cables were exposed, resulting in an unsightly appearance.

Furthermore, when installing a sprinkler, conventionally it has been attached to the concave steel 28 portion of the mounting frame 22a using the concave steel 28 shown in FIG. 6. Therefore, after changing the layout, it is not possible to relocate the sprinkler to the rectangular steel 21, and if it is relocated, the concave steel 28 shown in FIG. 6 must be newly installed before installing the sprinkler. It was hot.

Furthermore, since partitions and eyelids are installed directly under the rectangular steel, there is a limit in terms of load, and after the partitions and eyelids are relocated, the screw holes that were used to install them will be exposed, making it unsightly. There was a problem.

Therefore, it is difficult to simultaneously install devices other than the filter, such as lighting equipment, fire detectors, partitions, etc., on each of the conventional mounting frames, and when making a major layout change, it is difficult to install devices other than the filter at the same time. The problem was that the entire structure had to be completely removed and a new one had to be rebuilt, resulting in significant time and cost damage.

The present invention aims to solve the above-mentioned problems by providing a frame for mounting a filter in a laminar flow clean room.

[Means for Solving the Problems] The present invention provides a structure in which bent pieces are hung downward from both ends of an upper plate having a width sufficient to attach electric lights and other equipment; A mounting frame is formed by protruding mounting pieces facing each other, providing an opening at the lower end, and forming a hollow part on the upper surface of the opening, and joining and fixing the shaped steel members into a frame shape. On the other hand, by adopting a method of covering the openings other than the mounting positions of electric lights and other equipment by fixing the step part of the decorative panel board having a convex cross section to the mounting piece, the above-mentioned problem can be solved. solved.

[Function] According to the present invention having the above-mentioned configuration, the shaped steel material constituting the mounting frame is formed of a material having a width sufficient for mounting electric lights and other equipment, and having an opening on the lower surface. Therefore, even if the layout is changed, the existing mounting frame can be used as is, and the exposed part is shielded by the decorative panel board, and by being shielded by the decorative panel board, the mounting frame can be The lower surface is held flat without any protrusions.

[Example] An example of the implementation of the present invention will be described in detail with reference to the drawings. The steel molding material 3 constituting the mounting frame 2 of the filter 1 used in a full-surface laminar flow clean room is used for the electric light or the like to be installed and fixed. Bent pieces 5 are vertically bent at right angles downward from both ends of the top plate 4, which has a width sufficient to mount accessory equipment such as ballasts and other equipment such as fire detectors and sprinklers; In addition, mounting pieces 6 are provided protruding from the lower side of the bent pieces 5, facing each other on the inner lower surface thereof, for fixing a decorative panel plate 14, a holding plate 13 of the electric light 10, etc., which will be described later, from below with screws, etc., and openings are provided at the lower ends thereof. A steel material is used which is formed by providing a portion 7 and a hollow portion 8 on the upper surface of the opening portion 7.

Then, the shaped steel materials 3 are joined and fixed in a frame shape to form the mounting frame 2 of the filter 1,
The mounting frame 2 is suspended and fixed to the ceiling via hanging bolts 9, and the filter 1 is placed and fixed on the mounting frame 2. For example, when installing a light 10, a connecting cable 11 or a stabilizer is placed inside the empty space 8.
