Description

The present invention relates to a building ceiling and a construction method thereof.

In the construction of the ceiling of a building, the ceiling surface material is attached to the ceiling base material such as the field edge by fixing means (screws, screws, etc.) using a special tool in the upward work. Installation of this ceiling surface material requires experience and skill, and it is not a task that anyone can do. Nowadays, labor shortages are being criticized and labor saving technology is eagerly desired, and the development of technology that allows anyone to easily construct a building ceiling has become an issue.

On the other hand, ceiling surface materials such as gypsum board are generally constructed by abutting, but in the abutting construction, there is a problem that the gap is conspicuous when a gap is generated between adjacent ceiling surface materials. In order to eliminate the occurrence of gaps, measures such as interposing a joint material between the ceiling surface materials are taken, but the construction of the joint material also requires experience and technology as described above, and the construction period is lengthened and materials are required. New challenges such as increased costs arise.

Here, a suspended ceiling construction method has been proposed that achieves labor saving, eliminates the generation of waste materials, and provides a base material with a simple and clean finish. Specifically, a suspended ceiling base material is constructed of a base material piece that is bonded to the field edge and the ceiling material mounting surface of the field edge in a size that secures at least a ceiling material mounting allowance, and this suspended ceiling. This is a method in which the base material is arranged on the suspension member at appropriate intervals to form a base frame for laying the ceiling material, and then the ceiling material is attached to one side of the adjacent base base material (see, for example, Patent Document 1).

Further, in the illustrated example, the ceiling surface material 40 having a width slightly larger than the width between the adjacent field edges 31 is attached to each field edge 31 in order, but the ceiling surface material is the field edge 31-2. It may have a width of about three spans or three spans, and the ceiling surface material may be attached to the field edge 31 every other or every two.

As is clear from FIG. 8, in the building ceiling 50, since the edges 41 and 42 of the adjacent ceiling surface materials 40 are overlapped with each other, a gap is generated between the ceiling surface materials as in the case of butt. There is no.

Further, since the ceiling surface material 40 is formed of a lightweight and thin plate material, the installation of the ceiling surface material 40 can be facilitated, and the influence of the weight of the ceiling surface material 40 on the building frame can be suppressed. ..

Further, since the ceiling surface material 40 is thin, even if the edges 41 and 42 of both the first ceiling surface material 40A and the second ceiling surface material 40B are overlapped with each other, the step at the overlapped portion becomes inconspicuous. A neat overlapping line can be formed.

Further, since the ceiling surface material 40 is formed of a plate material, the ceiling surface material 40 has a certain degree of rigidity. Therefore, the overlapping portion of the ceiling surface materials 40 is fixed by the fastener 20A which is a snap button. Good fastening performance is ensured when fastening.

Further, the button hole 43 of the first ceiling surface material 40A is inserted into the first male portion 22 of the male snap button 21, and the first male portion 22 and the second female portion 28 of the relay snap button are fastened. The button hole 43 of the second ceiling surface material 40B is inserted into the second male portion 29 of the relay snap button 27, and the second male portion 29 and the first female portion 26 of the female snap button 25 are fastened to the ceiling surface material. Since the 40 is attached, anyone, including an amateur with no experience or skill, can easily construct the building ceiling 50.

The illustrated building ceiling 50 may be applied to either a temporary building or a permanent building. Examples of temporary buildings include temporary arenas for outdoor events, temporary housing that requires immediate construction after the earthquake, and temporary accommodation facilities. In addition, examples of the main building include large stores such as commercial facilities and leisure facilities, factories, office buildings (system ceilings), medical / welfare facilities, government offices, hotels and accommodation facilities, educational facilities, and the like.
