Description

  The present invention relates to a frame structure constituting a ceiling of a clean room or the like and a ceiling structure using the frame.

  Generally, in a clean room, the number of suspended particles in the air is controlled so as to be always below a predetermined value, and the room is controlled to be maintained at a predetermined temperature and humidity. Various control methods are known. For example, a ceiling frame member is suspended and supported on the ceiling, and the ceiling member is attached to the frame to form an airtight ceiling space. A fan filter unit is provided in the space behind the ceiling to purify the air taken in from the room, and the purified air is blown out from the ceiling outlet into the room.

  FIG. 7 is a schematic view showing a ceiling frame of a clean room, and a plurality of parallel main materials (A), (A)... And a plurality of orthogonal main materials (A), (A). It forms a lattice shape composed of parallel secondary materials (b), (b). This lattice-like frame is suspended and fixed by suspension bolts or the like. In addition, a ceiling panel is arranged in the space (c) surrounded by the main materials (b), (b), and sub-materials (b), (b) ... Is configured.

  By the way, the secondary material (b), (b) ... orthogonal to the main material (b), (b) ... is connected with the both ends being butted against the sides of the main material (b), (b) ... However, an L-shaped bracket, a T-shaped bracket, or a ten-shaped bracket is used as the connecting member. In other words, the bolts are tightened through each of these brackets, but the workability is poor, and the secondary materials (b), (b) ... are correctly abutted against the main materials (b), (b) ... It is not easy to connect, and sometimes a gap is formed on the butt surface.

The “ceiling frame structure” according to Japanese Patent Application Laid-Open No. 2006-112222 is a structure in which the main material and the auxiliary material constituting the ceiling frame can be easily connected and detached.
That is, the main material is provided in parallel along the ceiling surface, the auxiliary material that intersects the main material is provided in parallel along the ceiling surface between the adjacent main materials, and the end surface of the auxiliary material is the side surface of the main material. In the lower part of the side face, a groove having an upward opening is provided. The L-shaped cross-section metal fitting is applied to the abutting side face so that the bent edge is located at the side abutting edge of the main material and the sub-material, and the lower edge of the cross-section L-shaped metal fitting is fitted in the groove. . A downward U-shaped fixing member is provided on the same side surface upper part as the groove to form a downward opening groove, and the upper edge of the L-shaped metal fitting is fitted into the groove.

However, this ceiling frame structure requires an L-shaped bracket and a U-shaped fixing bracket at the connecting portion of the main material and the secondary material, and the U-shaped fixing bracket is fixed when removing the secondary material. You must loosen and remove the bolts and remove the L-shaped bracket. Of course, when the secondary material is connected to the main material, the bolt must be bolted using an L-shaped bracket and a U-shaped fixing bracket.

Therefore, when attaching the secondary material, the connecting member is fixed to the tip of the secondary material in advance, the connecting member is placed on the ceiling member of the main material, and the upper end thereof is bolted to the main material. Alternatively, the connecting member can be fixed to the main material in advance, and the fitting portion of the connecting member can be fitted into the hole of the secondary material and can be bolted to the arm of the connecting member. In either case, the secondary material can be connected to the main material by simply tightening one bolt, and the mounting operation is extremely simple.

The connecting member is fixed to the front end of the secondary member without being displaced due to the fitting portion being fitted in the hole, and the fixed connecting member is placed on the ceiling panel receiver of the main material, and the lower end thereof is the ceiling panel receiver. As a result, the secondary material is connected perpendicularly to the main material.
In addition, a ceiling panel receiver is provided at the lower end of the main material and the auxiliary material, the ceiling panel is mounted on and supported by the ceiling panel receiver, and the adjacent ceiling panels are connected via a connecting member having an approximately E-shaped cross section, The joint space between the ceiling panels is blocked.
