Since the sealing material applied to the design surface at the boundary between the ceiling panel and the ceiling panel support member can be seen from inside the bathroom, it is necessary to finish the surface cleanly. Therefore, when applying the sealing material, it is necessary to attach masking tape or wipe the surface of the sealing material with a spatula or the like to make it smooth. Therefore, the conventional bathroom ceiling structure has a problem that it takes a long time to construct the ceiling panel and it requires skill to finish the sealing material neatly without the occurrence of water leakage.

In addition, Patent Document 1 discloses that a sealing material is applied in the groove into which the panel is inserted, and water is stopped by inserting the panel. Since the sealing material is applied to the inside of the groove and is not visible from the indoor side, it is not necessary to arrange the finish neatly. However, since the sealing material cannot be confirmed when the panel is inserted into the groove, there remains a problem that the water stop state cannot be confirmed by the technique disclosed in Patent Document 1.

Therefore, the present invention provides a bathroom ceiling structure that can easily secure water stoppage in a short time without the need for masking or finishing when applying the sealing material, and can easily confirm the water stoppage state. With the goal.

FIG. 2 is a cross-sectional view of a main part of the bathroom ceiling structure according to the present invention. FIG. 3 is a perspective view showing a cross-sectional view of a ceiling panel support member used in the bathroom ceiling structure according to the present invention.
The bathroom ceiling structure shown in this embodiment shows an example of a ceiling structure used in a unit type bathroom. In this bathroom ceiling structure, a beam-shaped panel 2 is attached to the upper end of the bathroom wall panel 1, and a ceiling panel 3 is attached to the upper end of the beam-shaped panel 2.

The beam-shaped panel 2 is formed in an L-shape by connecting the lower surface beam panel 21 and the side beam panel 22 at right angles, and is fixed to a bathroom frame or the like (not shown) by brackets 21a and 22a. A beam panel support member 23 is attached to an end portion of the lower surface beam panel 21 of the beam type panel 2. Further, a beam-shaped panel fixing metal fitting 11 is attached to the upper end of the bathroom wall panel 1. The beam type panel 2 is connected to the bathroom wall panel 1 by holding the beam type panel support member 23 on the beam type panel fixing metal fitting 11.

The ceiling panel 3 is attached to the upper end portion of the side beam panel 22 of the beam type panel 2 via the ceiling fixing metal fitting 4 and the ceiling panel support member 5.

The ceiling fixing metal fitting 4 has a metal fitting main body 41, an upper end plate portion 42, and a lower end plate portion 43. The metal fitting body 41 is arranged on the surface of the side beam panel 22. The upper end plate portion 42 is bent and formed from the upper end portion of the metal fitting body 41. The lower end plate portion 43 is bent and formed from the lower end portion of the metal fitting body 41. As a result, the ceiling fixing metal fitting 4 is formed in a U-shaped cross section.

As shown in FIGS. 2 and 3, the ceiling panel support member 5 has a support member main body 51 and a folded portion 52. The support member main body 51 is formed in a flat plate shape. The folded-back portion 52 is provided so as to project laterally from the lower end portion of the support member main body 51. The support member main body 51 and the folded-back portion 52 extend continuously in the length direction.

The folded-back portion 52 has an upper surface plate portion 52a and a lower surface plate portion 52b. The upper surface plate portion 52a is formed so as to project laterally from the lower end portion of the support member main body 51. The lower surface plate portion 52b is formed by being folded back from the tip end portion of the upper surface plate portion 52a toward the support member main body 51 side again. A slit-shaped mounting groove 53 for inserting the lower end plate 43 of the ceiling fixing bracket 4 is formed between the upper plate 52a and the lower plate 52b.

A waterproof packing 54 is provided at the tip of the folded-back portion 52 so as to elastically contact and seal the lower surface (panel surface) 3b of the ceiling panel 3. The ceiling panel support member 5 has a lower end plate portion 43 of the ceiling fixing bracket 4 inserted into the mounting groove portion 53, and is fixed to the side beam panel 22 together with the ceiling fixing bracket 4 by a screw 6.

The ceiling panel support member 5 has a holding rib 55. The pressing rib 55 is formed so as to project laterally from the support member main body 51. The pressing rib 55 is composed of a protruding plate portion 55a, a side plate portion 55b, and a pressing plate portion 55c, and extends continuously in the length direction.

The projecting plate portion 55a projects laterally from a portion of the surface of the support member main body 51. The protruding plate portion 55a is near the central portion in the height direction (vertical direction in FIG. 2) of the support member main body 51, and has a distance larger than the thickness of the ceiling panel 3 with respect to the upper surface plate portion 52a of the folded portion 52. It is placed in the same position. The protruding height (horizontal length in FIG. 2) of the protruding plate portion 55a from the surface of the support member main body 51 is sufficiently smaller than the protruding height of the folded-back portion 52 from the surface of the support member main body 51.

The side plate portion 55b is integrally formed so as to bend downward from the tip of the protruding plate portion 55a toward the folded portion 52. The downward length of the side plate portion 55b is such that a distance slightly larger than the thickness of the ceiling panel 3 is provided between the side plate portion 55b and the upper surface plate portion 52a of the folded portion 52.

The holding plate portion 55c projects laterally and slightly downward from the lower end of the side plate portion 55b. The tip of the pressing plate portion 55c is arranged so as to be able to elastically contact the upper surface (rear surface of the panel) 3a of the ceiling panel 3.

The ceiling panel support member 5 forms an insertion groove portion 56 for inserting and supporting the end portion 3d of the ceiling panel 3 between the folded-back portion 52 and the holding rib 55. Further, the ceiling panel support member 5 forms an escape space portion 58 of the sealing material 7 by the support member main body 51, the projecting plate portion 55a of the pressing rib 55, and the side plate portion 55b.

The end portion 3d of the ceiling panel 3 is inserted into the insertion groove portion 56 and is supported in a state of being sandwiched between the upper surface plate portion 52a of the folded portion 52 and the pressing plate portion 55c of the pressing rib 55. As shown in FIG. 2, a sealing material 7 made of, for example, silicon for sealing the end portion 3d of the ceiling panel 3 is housed in the insertion groove portion 56. The sealing material 7 in the insertion groove portion 56 has penetrated into the escape space portion 58 from between the support member main body 51 and the end portion 3d of the ceiling panel 3.

The protruding plate portion 55a of the pressing rib 55 is formed with a sealing material overflow portion 57 formed of a through hole that communicates the inside and the outside of the insertion groove portion 56. The sealing material overflow portion 57 shown in the present embodiment is formed in an elongated hole shape, but the hole shape is not limited, and may be, for example, a round hole, a square hole, a slit-shaped hole, or the like. A plurality of sealing material overflow portions 57 are formed on the protruding plate portions 55a at predetermined intervals in the length direction of the ceiling panel support member 5.

The sealing material 7 exists so as to fill between the inner surface of the insertion groove portion 56 and the end portion 3d of the ceiling panel 3 inserted into the insertion groove portion 56, and the ceiling panel 3 is arranged in the insertion groove portion 56. The end 3d is held in a watertight state. The sealing material 7 penetrates into the escape space 58 from between the end surface 3c of the ceiling panel 3 and the support member main body 51, and a part of the sealing material 7 overflows the sealing material formed in the projecting plate portion 55a. It overflows from the portion 57 to the outside of the insertion groove portion 56. Therefore, by visually checking the sealing material 7a overflowing from the sealing material overflowing portion 57, the sealing material 7 is surely applied to the insertion groove portion 56, and the periphery of the end portion 3d of the ceiling panel 3 is stopped. It can be easily confirmed that this is the case. The sealing material overflow portion 57 is an example of the "confirmation means" of the present invention.

The sealing material 7 at the end 3d of the ceiling panel 3 exists so as to come into contact with the ceiling panel 3 from the end surface 3c to the upper surface 3a. Therefore, the end portion 3d of the ceiling panel 3 in which the sealing material 7 is present includes both the end surface 3c and the upper surface 3a of the ceiling panel 3.

In the insertion groove portion 56, the ridge portion 59 is formed on the upper surface plate portion 52a of the folded portion 52 that supports the lower surface 3b of the ceiling panel 3. The ridge portion 59 is located below the side plate portion 55b of the holding rib 55, is formed so as to extend along the length direction, and is in contact with the lower surface 3b of the ceiling panel 3 inserted in the insertion groove portion 56. .. The sealing material 7 in the insertion groove portion 56 is housed on the support member main body 51 side of the protrusion portion 59, and does not protrude from the protrusion portion 59 toward the tip end side of the folded portion 52.

Next, a method of attaching the ceiling panel 3 to the ceiling panel support member 5 will be further described with reference to FIGS. 4 and 5.
First, the sealing material 7 is applied to the inside of the insertion groove 56 of the ceiling panel support member 5 (FIG. 4). The sealing material 7 is applied to the inner side of the insertion groove 56 in a sufficient amount along the length direction of the ceiling panel support member 5. At this time, the ridge portion 59 of the upper surface plate portion 52a of the folded portion 52 can function as a guide for applying the sealing material 7. That is, by applying the sealing material 7 to the inner side of the insertion groove portion 56 from the ridge portion 59, when the end portion 3d of the ceiling panel 3 is inserted into the insertion groove portion 56 in the next step, the sealing material 7 Can be prevented from leaking to the bathroom side, and at the same time, it can be confirmed that a necessary and sufficient amount of the sealing material 7 has been applied to the inside of the insertion groove portion 56.

Next, the end portion 3d of the ceiling panel 3 is inserted into the insertion groove portion 56 coated with the sealing material 7 (FIG. 5). As a result, the sealing material 7 is crushed between the end surface 3c of the ceiling panel 3 and the support member main body 51. Most of the crushed sealing material 7 faces upward and penetrates into the upper surface 3a of the ceiling panel 3 and the escape space 58.

Further, the ceiling panel 3 is inserted all the way into the insertion groove 56, and when the installation of the ceiling panel 3 is completed, the sealing material 7 is most crushed and overflows from the inside of the escape space 58 through the sealing material overflowing portion 57 to the outside. The protruding and overflowing sealing material 7a protrudes from the sealing material overflowing portion 57 (FIG. 2). At this time, the end portion 3d of the ceiling panel 3 in the insertion groove portion 56 is covered with the sealing material 7 from the end surface 3c to the upper surface 3a, and the water is reliably stopped.

As described above, according to the bathroom ceiling structure shown in the present embodiment, since the sealing material 7 is housed in the insertion groove portion 56 of the ceiling panel support member 5, it is not visually visible from the outside. Therefore, it is not necessary to prepare masking or finishing when applying the sealing material 7. Further, since the sealing material 7 only needs to be applied so as to be accommodated in the insertion groove portion 56, the water stopping work can be easily performed in a short time without requiring skill. Therefore, the water stoppage can be easily ensured by a simple operation of inserting the ceiling panel 3. Moreover, since the operator can confirm that sufficient sealing material 7 has been applied to the inside of the insertion groove 56 only by looking into the back side of the ceiling panel 3 and visually observing the sealing material 7a overflowing from the sealing material overflowing portion 57. , It is easy to check the water stop state. Therefore, according to the bathroom ceiling structure shown in the present embodiment, it is possible to easily construct a bathroom ceiling structure in which water is reliably stopped.

Further, when the ceiling panel 3 is inserted into the insertion groove portion 56, the ridge portion 59 abuts on the lower surface 3b of the ceiling panel 3 and seals between the lower surface 3b and the upper surface plate portion 52a of the folded portion 52. It is possible to surely prevent the sealing material 7 from leaking into the bathroom from between the lower surface 3b and the upper surface plate portion 52a.

Further, the insertion groove portion 56 has a relief space portion 58 for the sealing material 7 on the upper surface 3a side of the ceiling panel 3, so that the insertion groove portion 56 is sufficiently inside the insertion groove portion 56 into which the end portion 3d of the ceiling panel 3 is inserted. The amount of the sealing material 7 can be accommodated, and the water stopping property can be further enhanced. Moreover, since the sealing material overflow portion 57 is arranged at a position corresponding to the escape space portion 58 and communicates with the escape space portion 58, a sufficient amount is contained in the escape space portion 58 even after the ceiling panel 3 is inserted. It can be easily confirmed that the sealing material 7 of the above is filled.

The sealing material overflow portion 57 described above is arranged on the protruding plate portion 55a of the pressing rib 55, but is not limited to this. For example, the sealing material overflow portion 57 may be formed on the side plate portion 55b of the pressing rib 55.

Further, the sealing material overflowing portion may have a configuration in which a part of the sealing material 7 overflows from between the pressing plate portion 55c of the pressing rib 55 and the upper surface 3a of the ceiling panel 3. For example, the seal material overflow portion can be formed by a groove in which the gap between the holding plate portion 55c and the upper surface 3a of the ceiling panel 3 is partially enlarged. A plurality of sealing material overflowing portions formed of such grooves are formed at intervals in the length direction of the holding plate portion 55c, so that the sealing material 7 overflows to the upper surface 3a of the ceiling panel 3. The effect is obtained.

Further, the confirmation means in the present invention is not limited to the sealing material overflow portion described above. The confirmation means has a configuration capable of visually confirming that the sealing material 7 pressed against the end portion 3d of the ceiling panel 3 exists between the inner surface of the insertion groove portion 56 and the end portion 3d of the ceiling panel 3. Anything is fine. Therefore, the confirmation means may be configured, for example, by forming a transparent portion or a translucent portion capable of seeing through the inside in at least a part of the pressing rib 55.

Further, when the ceiling panel 3 is attached to the ceiling panel support member 5, the sealing material 7 is applied to the end portion 3d of the ceiling panel 3 instead of the method of applying the sealing material 7 in the insertion groove portion 56 of the ceiling panel support member 5 in advance. Then, the ceiling panel 3 with the sealing material may be inserted into the insertion groove portion 56 of the ceiling panel support member 5.

The lower surface beam panel 21 of the beam type panel 2 shown in the present embodiment also constitutes a part of the ceiling of the bathroom and can be said to be a ceiling panel. Therefore, although not shown, the same configuration as the ceiling panel support member 5 described above can be applied to the beam panel support member 23 that attaches the lower surface beam panel 21 to the bathroom wall panel 1. As a result, the same effect as described above can be obtained in the mounting structure of the lower beam panel 21.

Further, the bathroom ceiling structure according to the present invention is not limited to a structure in which the ceiling panel 3 is attached to the beam-shaped panel 2, and although not shown, a structure in which the ceiling panel 3 is attached to the upper end of the wall panel of the bathroom. Can be applied to.
