BACKGROUND OF THE INVENTION 1. Field of the Invention In a suspended ceiling structure, the present invention forms a grid-like frame section on the ceiling surface and directly supports the ceiling plate and the equipment for construction equipment arranged on the ceiling surface. About the ceiling frame that can be.

[0002]

2. Description of the Related Art In the conventional suspended ceiling structure, a large number of long-shaped frame rims are equally spaced in a ceiling construction space on a suspension bolt suspended from a deck plate used in a ceiling slab. Suspended to the bottom of each field stake, long fields are arranged in a cross shape on the underside of the field stake and the field stake and the field stake are connected and fixed appropriately with connecting fittings, and the ceiling plate is fitted to the bottom of the field stake. It can be said that a typical structure is fixed or stretched and fixed with nails, bolts or the like. However, such a conventional suspended ceiling structure has the following drawbacks.

A. In the above-mentioned conventional suspended ceiling structure, main parts, for example, field edge receivers, field edges, etc., are mainly semi-made members whose length is not constant,
With regard to the field bridge, its position is affected by the position of each suspension bolt, and with respect to the field frame, the positioning must be done in accordance with the position of the ceiling plate, and even if only one marking operation is performed, It has to be performed a significantly large number of times depending on the individual situation at the site, and it must be done manually by cutting the members to the prescribed size on site, mainly by hand. There is a lot of work that cannot be done, construction becomes complicated, and work efficiency does not improve. B. In the above-mentioned conventional suspended ceiling structure, as described above, the position of each hanging bolt is affected by the position of each hanging bolt for the field edge receiver, and the position of the field edge is adjusted according to the position of the ceiling plate. In many cases, the connection position between the field bridge and the field frame is not constant, and the stress in each member of the ceiling frame can only use approximate values, and there are cases in which mechanically useless members are used. Many will lead to higher construction costs.

C. In the above-mentioned conventional suspended ceiling structure, since a useless member is used as described above, a complicated ceiling frame must be formed in a narrow ceiling construction space,
From that point of view, the construction is often complicated and difficult,
In the case where piping for building equipment such as air conditioning is carried out using a narrower ceiling construction space, various obstacles in construction are caused. In order to overcome the drawbacks of such a conventional suspended ceiling structure,
Recently, instead of the double structure of the ceiling frame composed of the field frame and the field frame, a frame structure on one surface has been proposed, but the deformation of the frame cross member and the fixed size between the joint parts of the frame members are also proposed. However, due to the influence of the position of each suspension bolt and other external force, the ceiling frame is distorted and the ceiling board is not supported. This results in difficult mounting and further distortion of the mounted ceiling panel.
