Description

[Detailed description of the invention] The present invention relates to a ceiling board mounting structure, and more specifically, when installing a ceiling board by nailing it to the lower end of a mounting bar for installing a floor joist or a ceiling board. Vibration from the upper floor is not directly transmitted to the ceiling board by interposing vibration isolating material made of elastic material or foam material between the lower end surface and the back surface of the ceiling board and between the surface of the ceiling board and the heads of the mounting nails. Regarding the mounting structure of ceiling panels.

Conventionally, the ceiling of a building has not been constructed integrally with the floor assembly, but has typically been erected via hanging materials.

However, in today's buildings, in order to reduce the need for large ceiling heights and to reduce the amount of materials used, so-called direct-attached ceilings, in which ceiling materials are directly attached to floor structure components, are becoming more common.

Furthermore, as the form of living rooms in buildings gradually became more and more popular, rooms with large halls became preferred, and for this reason, the spacing between columns and wall spans became larger.

As a result, vibrations from the upper floor were directly transmitted to the ceiling panels on the lower floor, causing discomfort to those living on the lower floor.

With the above-mentioned floor construction and pillar and wall arrangement in living rooms, a ceiling board mounting structure has been required for the purpose of vibration and soundproofing.

Therefore, this proposal was made based on the above request, and by interposing vibration isolating material in the attachment part when attaching the ceiling board with nails, the vibrations from the upper floor will be transmitted to the ceiling board on the lower floor. Moreover, the present invention provides a ceiling board mounting structure that can be mounted extremely easily.

Hereinafter, the ceiling plate mounting structure according to the present invention will be explained in detail based on the drawings.

FIG. 1 is a partially omitted sectional view showing an outline of a ceiling plate mounting structure according to the present invention.

That is, floor joists 1, 1, . . . are constructed from beams and girders provided as structural members of the building for each required span, and the upper floor floor boards 2 are stretched over the upper surfaces thereof.

A ceiling mounting beam 4 is fixed at a predetermined position on the wall surface 3 of the living room of the building.

In such a state, the ceiling board 5 is stretched for each span so as to abut the lower end surface 11 of the floor joist 1 and the lower end surface 41 of the mounting beam 4, respectively.

As a metal fitting for fixing the ceiling plate 5 to the lower end surface 11 of the floor joist 1 and the lower end surface 4 of the mounting crosspiece 4, a mounting nail 6 as shown in FIG. 2 is used. This installation nail 6 consists of a nail head 61 and a body 62, and usually the nail head 61
The body part 62 is attached to the adherend by hitting it with a hammer or the like to penetrate the body part 62 into the object.

Therefore, a screw-shaped stepped portion 63 may be provided on the body portion 62 in order to increase the pull-out resistance.

Furthermore, when used in the mounting structure of the present invention, in order to block vibrations and noise from the floor joists 1 and the mounting crosspieces 4, the nail heads 61 in the body 62 should be prevented from coming into direct contact with the ceiling board 5. Nearby, a narrow diameter portion 64 is formed with a length l longer than the thickness of the ceiling plate 5.

The detailed structure for attaching the floor joists 1 and the mounting beams 4 in the ceiling board mounting structure of the present invention described above with reference to FIG. 1 will be explained with reference to FIGS. 3 and 4.

FIG. 3 is a partially omitted enlarged sectional view showing a state in which the ceiling plates 5, 5 are attached to the floor joist 1.

First, a flat plate-shaped vibration isolator 7 made of rubber or styrofoam is placed on the lower end surface 11 of the floor joist 1.

Then, the ceiling plate 5 is disposed so as to sandwich the vibration isolating material 7 with the floor joists 1 in contact with each other. Furthermore, a vibration isolating material 7 similar to that described above is provided on the surface of the ceiling plate 5 at approximately the same location. In this state, the mounting nail 6 is driven into the floor joist 1 by penetrating each of the vibration isolating material 7, the ceiling board 5, and the vibration isolating material 7.

The mounting nail 6 is attached to the body 62 as shown in FIG.
Since the tip of the nail hole is formed to have a larger diameter than the narrow diameter part 64, the tip of the body part 62 leads the nail hole when driving, so the diameter of the nail hole is larger than the narrow diameter part 64 (approximately the same diameter as the body part). is perforated. Also, since the length l of this narrow diameter portion 64 is longer than the thickness of the ceiling board 5, if the nail head 61 is driven until it touches the vibration isolating material 7, the narrow diameter portion 64 will fit into the nail hole without coming into contact with the surroundings. It can be paid in

Therefore, the ceiling board 5 is attached to the mounting nails 6 and without directly contacting the floor joists 1.

On the other hand, in such a state, the nail heads 61 of the mounting nails 6 remain exposed on the surface of the ceiling board, which is not desirable in terms of the exterior design of the living room.

Therefore, when driving the mounting nails 6, the exterior body receiving material 8
1 at the same time and the exterior body 8 is attached to the exterior body receiving member 81, the mounting nails 6 will be covered and the exterior design of the ceiling in the living room will not be spoiled.

Furthermore, this exterior body 8 is used as a long material to form ceiling panels 5, 5.
If they are placed at the required intervals between joints, they can also have a design effect as a ceiling joint material.

FIG. 4 is a partially omitted enlarged cross-sectional view showing a state in which the ceiling plate 5 is attached to the lower end surface 41 of the ceiling mounting bar 4. FIG.

This mounting structure is also almost the same as the mounting structure of the floor joist 1 explained in FIG. Leave the end of 7 rolled up,
Further, although not shown, a flexible lug made of rubber or synthetic resin is integrally formed in the longitudinal direction at the side end of the exterior body 8 which is brought into contact with the inner wall surface 3. This seals the boundary between the inner wall surface 3 and the ceiling plate 5, which has the effect of improving airtightness in the living room.

In this mounting structure of the ceiling mounting beam 4, the exterior body 8 plays the role of a so-called surrounding edge material that hides the inner wall surface 3 and the corner part of the ceiling board 5.
Similar to the joint material in the floor joist 1 described above, the ceiling board 5 can also sufficiently exhibit its aesthetic effect.

As described above, the mounting structure of the present invention interposes vibration isolating material when installing the ceiling board 5, floor joists, and mounting beams, and the mounting nails used to install the ceiling board are in direct contact with the ceiling board. Therefore, the vibration transmitted from the upper floor is not directly transmitted to the ceiling board, but is absorbed and alleviated by the vibration isolating material on each joint surface.

Furthermore, the existence of the vibration isolating material and the exterior body further improves the airtightness of the living room, which has extremely technical and practical effects.
