Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to ceiling structures in various buildings, underground malls, etc.

[Conventional technology]

A ceiling structure in which ceiling panels of uniform dimensions corresponding to the squares are attached to the squares of a ceiling frame arranged in a grid pattern in a reversible manner has already been developed.
known as the system ceiling.

Generally, when a building is completed, lighting lights are arranged regularly on the ceiling, but sometime after the completion of the building, when the floors are divided by partition walls, the arrangement of the partition walls and the furniture in the partitioned rooms may change. Depending on the storage area, lighting lights that were regularly placed throughout the floor may be placed directly above a partition wall or bookshelf, which is an inconvenient arrangement both in terms of design and functionality. It may become.

System ceilings are designed to deal with such cases, and can replace a ceiling board with illumination that is in an inconvenient position with a ceiling board made of gypsum board, etc. located in a different grid. is possible.

[The problem that the idea attempts to solve]

By the way, in the above-mentioned system ceiling, if the ceiling board attached to the grid of the ceiling frame is a normal ceiling board with lighting lights, simply by allowing enough length for the electrical wiring,
It is possible to replace the ceiling board with another type of ceiling board made of gypsum board, etc. that does not have lighting lights, but the air supply ceiling board and exhaust ceiling board are connected to the air supply duct and exhaust duct in the attic, so the position may vary. cannot be changed.

Furthermore, the positions of the emergency lighting lights and fire detectors installed on the ceiling must be allocated according to the area of the floor, so the positions of the ceiling panels with emergency lighting lights and the ceiling panels with fire detectors cannot be changed.

In this way, in conventional ceiling structures, ceiling panels with standard dimensions are placed in the squares of the ceiling frame.
Ceiling board with emergency lighting, ceiling board with fire detector,
Since there are many ceiling panels such as air supply ceiling panels and exhaust ceiling panels that cannot be rearranged, the degree of freedom in rearranging the ceiling panels is low, and the equipment zone behind the ceiling is expanded, making it difficult to use as a system ceiling. The strengths of the company were not fully utilized.

In view of the above-mentioned drawbacks of the conventional system, the present invention aims to provide a ceiling structure that increases the degree of freedom in changing the arrangement of ceiling panels and further utilizes the advantages of a system ceiling.

[Means to solve the problem]

The technical measures taken by the present invention to solve the above problems are as follows. That is, the feature of the ceiling structure according to the present invention is that an air supply ceiling board to which an air supply duct is connected and an exhaust ceiling to which an exhaust duct is connected to squares at predetermined positions of a ceiling frame arranged in a grid pattern. At the same time, ceiling plates other than the air supply ceiling plate and the exhaust ceiling plate are arranged in a fixed manner in squares other than the squares, and the exhaust ceiling plate is connected to the center plate part. It is composed of a rectangular plate with a plate part with ventilation holes located around it, and emergency lighting and a fire detector are installed in the central plate part, and an emergency alarm etc. is installed above this exhaust ceiling board. The point is that the speakers used for this are installed.

[Effect]

According to the above configuration, since emergency lighting lights, fire detectors, speakers used for emergency alarms, etc., which cannot be repositioned, and exhaust ceiling panels are placed together, the ceiling panels cannot be relocated. The number of ceiling panels decreases, and the number of ceiling panels that can be rearranged increases accordingly.
