BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling construction method applied to buildings such as general buildings and high-rise buildings, which is capable of rationalizing ceiling construction by integrating construction finishing work and equipment work.

[0002]

2. Description of the Related Art Conventionally, when constructing a ceiling in which lighting equipment, air conditioning equipment, fire extinguishing equipment and the like are incorporated, a plurality of contractors have carried out the respective steps. That is, in the ceiling construction process, the process of incorporating the large frame of the ceiling, the electric facility process that incorporates lighting equipment, the air conditioning equipment, the air conditioning facility that provides the package air conditioner, the sanitary facility process that provides the drainage pipe and the water supply pipe, the sprinkler and the sensing process. There were processes such as fire extinguishing and fire prevention equipment processes for installing firearms, etc., and different contractors performed these processes in turn. further,
Even within the same contractor who carries out each process, the work was further subdivided and performed by different contractors (for example, a plumber, a heat insulator, and a painter in duct construction).

[0003]

However, when the ceiling construction is performed by the above method, the following problems occur. Since different contractors performed each equipment process step by step under their own construction management, the number of dedicated parts for each equipment increased, resulting in a ceiling structure with many parts. In addition to the time and effort required for mounting and adjustment between complicated processes, there is a risk that work may be reworked due to an adjustment error between contractors (between processes). It is necessary to perform piping connection work for each equipment in a narrow space in the ceiling, and also to frequently lift the ceiling board, which is the ceiling surface, from the floor surface position. It was

As a means for solving these problems, a plurality of ceiling finishing materials to serve as ceiling surfaces are arranged in advance on the ceiling frame at the floor level with good workability, and the above-mentioned facilities are incorporated into the ceiling frame, Lift the entire ceiling frame to the ceiling level with a lifter that freely lifts and lifts heavy objects such as a forklift, and hangs the ceiling frame by joining the ceiling frame to a hanging tool attached to the ceiling.
A unitized construction method for the ceiling has been developed and put into practical use, which can save labor in ceiling construction.

However, the above-mentioned unitized construction method has the following problems. That is, in the above-described ceiling unit construction method, a ceiling unit in which ceiling equipment is built into a ceiling frame of about 1600 mm square is usually used, and the number of connecting points such as piping attached to the ceiling unit increases. The ceiling unit is hoisted and the number of times of hanging is increased. Due to such problems as above, the work efficiency must be lowered, and some means for improving the work efficiency have been desired.

As a means for improving the work efficiency, it is conceivable to simply enlarge the ceiling unit for use, but in this case, the following problems occur. The work at the installation position is out of reach of the operator, which causes difficulty in assembling and requires a large assembling place. A large lifter is required to lift it, and its handling becomes poor. The radius of the ceiling frame becomes large. Therefore, it is difficult to efficiently form a highly accurate ceiling.

As a means for solving this problem, it is conceivable to increase the strength of the ceiling frame itself, but there is a problem that the cost of members increases and the construction cost also increases.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a construction method for ceiling construction which has high work efficiency, high construction accuracy, and low construction cost. There is.
