Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a ceiling panel mounting device in a clean room or the like.

Conventional technology In the past, clean room ceiling panels and beams were connected directly using bolts and nuts, or via hangers fixed to predetermined locations on the top surface of the ceiling panel with screws or rivets (for example, in a practical application). (See Publication No. 57-202517).

Problem to be Solved by the Invention However, in the former case, bolt holes are drilled in the ceiling panel and the beam in corresponding positions, and then they are connected using bolts and nuts. The work was extremely troublesome, and the head of the bolt protruded into the clean room from the bottom of the ceiling panel, creating turbulence in the airflow within the clean room. Also, according to the latter, since hangers are used, there are no objects protruding into the clean room.However, it is troublesome to fix the hangers to a predetermined location on the top of the ceiling panel, and moreover, the hangers are attached to the ceiling where they are connected to each other. They are attached alternately to both panels at predetermined intervals at the connecting ends of the panels, which poses the problem of an extremely large number of parts.

Conventionally, a ceiling panel holding rail member is attached to the lower end of a hanging bolt suspended from a beam material, and a ceiling panel holding member is attached to the upper side of the rail member so as to be movable up and down and connected to each other. The lower both ends of the ceiling panel holding rail member are engaged with the engagement hook strips of the ceiling panel's peripheral frame, and the legs of the ceiling panel holding member are tightened by tightening nuts screwed into the lower end portions of the hanging bolts. A ceiling panel connecting device is already known in which the ceiling panel is pressed against the upper surfaces of both ceiling panels (for example, see Japanese Utility Model Application No. 57-158812).

According to such a conventional panel connecting device,
It is true that there are no objects protruding into the clean room, but since the ceiling panel to be connected is attached to the lower end of the hanging bolt suspended from the beam, the ceiling panel is quite far away from the bottom of the beam. Therefore, the thickness of the ceiling (i.e., the height of the ceiling itself) cannot be kept low, which causes the problem that the height from the floor to the ceiling of a clean room, etc. cannot be made sufficiently high. Ta.

Furthermore, in conventional panel connecting devices, the distance between the ceiling panel and the beam is very wide, and although the distance can be adjusted, the height of the beam itself cannot be adjusted.

In addition, the conventional panel connecting device has a large number of parts and uses a large amount of materials, which makes the installation work of the ceiling panel troublesome and increases the cost.

Furthermore, in the past, hook-shaped engaging parts were provided on the bifurcated U-shaped part of a hanger for hanging a ceiling board, and these hook-shaped engaging parts were attached to a beam (C-shaped channel). 31, 31 are already known (see, for example, Japanese Utility Model Publication No. 12260/1983).

According to such conventional ceiling board hanging fittings,
It is true that ceiling panels can be attached near the bottom of the beams, and the thickness of the ceiling section (i.e., the height of the ceiling itself) can be kept very low, but in the past, ceiling panels that were to be connected to each other were In addition to the hanger, the connection was made using a bar with a relatively complex cross-sectional shape, roughly L-shaped, as well as bars and standing boards, which required a very large number of parts and materials. There was a problem that the construction cost of the ceiling was extremely high. In addition, with conventional ceiling board hanging brackets, the ceiling boards that are to be connected to each other are installed with a slight gap between them, which results in poor airtightness, and the lower wall part of the ceiling board mounting bar is attached to the ceiling. Since the bar protrudes from the lower surface of the bar, there is a problem in that the airflow flowing along the lower surface of the ceiling inside a clean room or the like hits the lower wall portion of these bars, causing turbulence in the airflow.

The purpose of this invention is to solve the above-mentioned problems of the conventional technology, and not only allows the ceiling panel to be installed near the bottom of the beam, but also allows the height of the beam itself equipped with the ceiling panel to be freely adjusted. , the ceiling level can be set very easily and accurately, and bolt heads etc. do not protrude from the bottom of the ceiling panel into the clean room, etc., thus causing turbulence in the airflow inside the clean room, etc. In addition, the installation of the ceiling panel is stable and it is easy to hold the panel horizontally during installation, so it is extremely easy to work with, and has a very small number of parts. The purpose of the present invention is to provide a ceiling panel mounting device for a clean room or the like, which reduces the cost of ceiling construction because less material is used.

Means for Solving the Problems In order to achieve the above-mentioned object, this invention includes a pair of left and right beam-constituting channel members having a cross section of 〓 and 〓, which are arranged with their openings facing outward; A hanger for mounting a ceiling panel having a lower engaging part at a vertical lower end, a bifurcated upper hanging part, and a ceiling panel mounting hanger having a substantially Y-shaped cross section and a substantially V-shaped bolt lower end relief recess when viewed from the front. The lower end portions of the required number of suspension bolts are arranged between the channel members constituting both the left and right beams, and a pair of upper and lower nuts and flat washers screwed onto each suspension bolt are used to connect both the left and right beams. The beam component channel member is clamped, and the lower end of each suspension bolt protrudes downward from the beam component channel member, and is released into the bolt lower end relief recess of the hanger, and the lower end of the hanger lower end. An upper horizontal wall is provided at the upper end of the vertical wall connected to the lower horizontal wall of the engagement part,
The gist of this invention is a ceiling panel mounting device for a clean room or the like, in which the upper horizontal wall is brought into contact with the lower surface of the upper wall of a recess provided with a groove-shaped reinforcing member at the connecting end of the ceiling panel.

Function According to the ceiling panel mounting device described above, a pair of left and right beam-constituting channel members with a cross section of 〓 and 〓 are held in place by a pair of upper and lower nuts and flat washers screwed onto each suspension bolt. In addition, the lower end of each suspension bolt protrudes downward from the beam constituting groove member and is released into the bolt lower end relief recess, which is approximately V-shaped when viewed from the front. The height of the beam itself, which is made of channel-shaped beams, can be adjusted freely, so the level of the ceiling can be set very easily and accurately.

The upper horizontal walls provided on both the left and right sides of the lower engaging portion at the lower end of the hanger are in contact with the lower surface of the upper wall of the recess provided with the groove-shaped reinforcement at the connecting end of the ceiling panel. Since the panel installation is stable and the panel can be easily held horizontally during installation, it is extremely easy to work with.

In addition, bolt heads and the like do not protrude from the lower surface of the ceiling panel into the clean room, etc., so that turbulence does not occur in the airflow inside the clean room, etc.

In the drawing, groove-shaped recesses 4, 4 are provided oppositely at connecting ends 1a, 2a of ceiling panels 1, 2 that are connected to each other in a clean room. Each of the ceiling panels 1 and 2 has a core made of a filling material such as asbestos honeycomb core or a heat insulating material such as foamed synthetic resin and glass wool, and aluminum plates are attached to both sides of the core material. recess 4,
Reinforcing members 5, 5 made of channel-shaped members are fitted inside the member 4. A beam is arranged horizontally above both ceiling panels 1 and 2. Here, the beam 3 is made up of certain channel members 7, 7 that are joined together with their openings facing outward. The beam 3 is clamped to the lower end portion 8a of a required number of suspension bolts 8 suspended from the roof of a semiconductor manufacturing factory, for example, via a pair of upper and lower nuts 9, 9 and rectangular flat washers 10, 10. It is being The lower end portion 8a of each suspension bolt 8 projects downward from the beam 3.

The ceiling panels 1, 2, which are connected to each other, are attached to the beam 3 via a mounting hanger 6 according to this invention. The hanger 6 is approximately Y-shaped when viewed from the front and is made of extruded aluminum, and is connected to the connecting end 1 of the ceiling panels 1 and 2.
