[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention holds one side edge of a ceiling panel on a receiving member and then raises the ceiling panel while rotating the ceiling panel about the one side edge to support the other side edge on the receiving member. Therefore, the present invention relates to a ceiling panel construction method capable of reducing the burden of upward work and simplifying construction.

[0002]

2. Description of the Related Art In recent years, prefabricated houses have been widely used in which the workability is improved by forming a floor, a wall and the like by using an integrally transportable panel body.

Also, as shown in FIG. 37, the ceiling portion of a house constructed by such a method is conventionally composed of a plurality of ceiling panels p ... Is lifted up using a stepladder or the like, and is attached to a horizontal receiving member c ... Made of, for example, lip channel steel by using the screws d.

[0004]

However, since the ceiling panel p is usually a heavy article of a dozen or more kilograms, the conventional construction method of lifting the ceiling panel p by using a stepladder and attaching it in an upward posture is as follows. Requires a lot of effort and attention,
The operator's fatigue was increased and the safety was poor.

Since the ceiling panel p and the steel receiving member c are in direct contact with each other, the surface temperature of the ceiling material b on the room side is
There is a difference between the place where the receiving member c is directly above and the place where the receiving member c is not present, and this is a cause of locally contaminating the ceiling surface formed by the ceiling material b due to adhesion of dust or the like due to dew condensation water.

In the present invention, one edge of the ceiling panel is held by the receiving member, and the other edge is raised while the ceiling panel is rotated around the one edge so as to be supported by the receiving member. As compared with the method of lifting the ceiling panel using a stepladder and attaching it to the receiving member, the burden on the operator can be reduced, the labor saving of the construction can be achieved, and the ceiling panel construction method that is also useful for improving safety It is intended to be provided.

[0007]

SUMMARY OF THE INVENTION The present invention is a ceiling panel construction method for mounting a rectangular ceiling panel that forms a ceiling of a house by arranging a plurality of sheets side by side. Lifting with the edge up, the one side edge is held by a receiving member provided in advance in the ceiling part, and the other side edge opposite to the one side edge is raised while the ceiling panel is rotated around the one side edge. And let the other edges
The ceiling panel is supported horizontally by the receiving member.

[0008]

In order to lift a rectangular ceiling panel with its one side edge upward and to hold the one side edge on the receiving member provided in advance on the ceiling part, when raising the other side edge of the ceiling panel while rotating it, The weight of the ceiling panel can be supported by the receiving member, the burden of upward work for supporting heavy objects can be reduced, the construction can be simplified and the labor can be saved, and the working time on an unstable scaffold such as a stepladder can be reduced. Therefore, it is possible to reduce the risk such as a fall accident of the ceiling panel and improve the safety.

Further, in the invention of claim 2, after the ceiling panel is lifted in a posture displaced by a certain angle with respect to the direction orthogonal to the receiving member to position the projecting piece above the receiving surface, the ceiling panel is removed. When the protrusion is placed on the receiving surface by rotating in the orthogonal direction and lowering the ceiling panel, one side of the ceiling panel is smoothly inserted between the two receiving members arranged in parallel. One edge of the lever can be easily held by the receiving member, and workability can be improved. Further, since the one edge is held by the receiving member by the projecting piece of the holder attached to one side edge of the panel base of the ceiling panel, the holding of the ceiling panel is conveniently held by the projecting piece of the holder. In addition to the above, the holder can be used in place of the screw for mounting the ceiling panel at one edge, so the screwing work can be reduced, and the workability on site can be further improved. For example, the supporting strength of the ceiling panel can be increased by using a metal having high strength as the holder.

Further, in the invention of claim 3, when the ceiling finishing material is previously attached to the lower surface of the ceiling panel, the finishing work in the upward posture can be omitted, and the workability on site can be improved.

Further, in the invention of claim 4, when a work port through which a person can pass for work is provided in advance on the ceiling panel, electric wiring, plumbing, etc., especially on a distribution board, toilet, etc., can be performed from the work port. It can be done conveniently without any hindrance.

Further, in the invention of claim 5, when the receiving member includes an overhanging piece for holding the projecting piece, and a gap is created between the overhanging piece and the panel base body by mounting the ceiling panel, the receiving member is received. Since the member and the ceiling panel do not come into direct contact with each other, it is possible to reduce the generation of stains on the ceiling surface of the living room due to the thermal bridge, and it is possible to prevent rattling of the ceiling panel by driving the wedge piece into the gap.

Further, in the invention of claim 6, a mounting surface is formed on one side of the panel base of the ceiling panel, and a support tool supported on the mounting surface is provided on the other side. Occasionally, adjacent ceiling panels can be easily assembled with a simple structure to improve the workability, and the work time can be shortened, so that the fatigue of the worker due to the upward posture can be reduced.
