JP6483970B2 - Connection structure for ceiling corners and construction method of bathroom ceiling edge members - Google Patents

Description

The present invention relates to a connection structure of a ceiling corner between a ceiling surface and a wall surface of a bathroom.

In recent years, bathroom repair and renovation (hereinafter referred to as refurbishment) has been actively performed. For example, refurbishment of bathrooms has been actively carried out such that sheets and panels are attached to the ceiling and wall surfaces of a bathroom along with replacement of a bathtub.
Patent Document 1 discloses a bathroom wall and ceiling connection structure in which a ceiling edge member having an elastic seal piece is inserted into a recessed portion formed between a ceiling panel and a horizontal piece of a bathroom. ing. Such a ceiling peripheral member is attached to a ceiling corner portion which is a portion between a ceiling surface and a wall surface of a bathroom called a so-called unit bath.
The ceiling edge member of Patent Document 1 is suitable for a recessed portion of a specific structure, but cannot be used for a recessed portion of any other structure, so when refurbishing the bathroom, attach it after attaching a sheet or panel. It is not always possible to use it again. If you cannot attach a ceiling rim member when refurbishing the bathroom, after attaching panels and sheets, you must waterproof the corners in the ceiling with caulking agent. However, the waterproofing treatment using the caulking agent is that the masking tape is stuck to the ceiling surface and the wall surface, the caulking agent is applied between the masking tapes and the surface is smoothed with a spatula, and the caulking agent is cured. Later, it is a time-consuming work of removing the masking tape. As described above, the waterproofing treatment with the caulking agent has many work steps and requires time for construction, and the quality of the finish depends strongly on the skill of the worker.

  Further, the corners of the ceiling of the bathroom are not necessarily a right angle, and often have an angle slightly larger than 90 degrees (that is, an obtuse angle) or an angle that is slightly smaller (that is, an acute angle). In some cases, a right-angle part, an obtuse-angle part, and an acute-angle part exist randomly. When inserting resin foam or coating caulking agent in the ceiling corner where such unevenness exists, the construction becomes more difficult, so the worker's advanced skill is necessary to finish with a good appearance However, the construction time will also increase. Therefore, there is a demand for a bathroom ceiling edge member that can be used simply and for general purposes.

[First Embodiment]
The bathroom ceiling edge member of the present invention is a building member attached to a ceiling corner between a ceiling surface and a wall surface of a bathroom.
In FIG. 1 thru | or FIG. 3 (a), the bathroom ceiling periphery edge member 1 is the elongate shape extended in one direction as a whole. The long shape means a shape in which the length in one direction is sufficiently longer than the length in the other direction (a direction orthogonal to the one direction). The long bathroom ceiling edge member 1 has, for example, a length in one direction of 100 cm or more, and preferably 200 cm or more. The long bathroom ceiling edge member 1 is cut into an appropriate length for use.
The bathroom ceiling edge member 1 includes a flexible main body 2 having a first surface 21 disposed on the bathroom wall surface and a second surface 22 disposed on the bathroom ceiling surface, and the first surface of the main body 2. 21 has a flexible first protrusion 31 projecting from the end of 21, and a flexible second protrusion 32 projecting from the end of the second surface 22 of the main body 2.
The bathroom ceiling edge member 1 has flexibility as a whole. The bathroom ceiling edge member 1 having a long flexible shape is formed, for example, in a length of about 5 m to 10 m in one direction, and can be stored and transported in a state of being wound around a roll. Excellent workability.
Since the bathroom ceiling edge member 1 has a long shape extending in one direction, the main body 2, the first protrusion 31, and the second protrusion 32 similarly extend in one direction. Therefore, the bathroom ceiling edge member 1 has the same cross-sectional shape even when cut at any location in the longitudinal direction, and the cross-sectional shape is the same as the planar shape shown in FIG.

The bathroom ceiling edge member 1 is formed of a flexible material. Here, flexibility refers to a property that is flexible enough to be easily deformed by the human power of the operator. The bathroom ceiling edge member 1 is flexible, so that the main body 2 is bent in the longitudinal direction, the first protrusion 31 is placed along the wall surface of the bathroom, and the second protrusion 32 is provided on the ceiling surface of the bathroom. Can be along. Preferably, the bathroom ceiling edge member 1 has elasticity that is substantially restored to the original state when the stress is applied and then the stress is released and then the stress is released. Since the bathroom ceiling edge member 1 has such elasticity, the first protrusion 31 and the second protrusion 32 are in good contact with the wall surface and ceiling surface of the bathroom. Furthermore, it is desirable for the bathroom ceiling edge member of the present invention to be flexible enough to be wound in a roll shape with one direction as the circumferential direction. If it is flexible to the extent that it can be wound in a roll shape, it can be stored or transported in the state of being wound on a roll as described above, and it is excellent in workability and can be easily operated along the uneven surface of the ceiling or wall.
For example, the hardness of the bathroom ceiling edge member 1 is 50 to 100, preferably 60 to 90, and more preferably 75 to 85. If the hardness is too small, the bathroom ceiling edge member 1 is difficult to handle, and if the hardness is too high, the bathroom ceiling edge member 1 may be difficult to deform. However, the hardness refers to a value measured by durometer type A according to JIS K 6253.

The bathroom ceiling edge member 1 is not particularly limited as long as it has flexibility. For example, the bathroom ceiling edge member 1 is formed using an elastomer, rubber or the like.

The long bathroom ceiling edge member 1 can be obtained by extruding the elastomer or the like from a pressure resistant mold.

The main body 2 is formed between the first surface 21 disposed on the wall surface of the bathroom during construction, the second surface 22 disposed on the ceiling surface of the bathroom during construction, and the first surface 21 and the second surface 22. And a ridge portion 4 arranged at the corner of the ceiling of the bathroom at the time of construction. Preferably, the bathroom ceiling edge member 1 adheres the first surface 21 of the main body 2 to the wall surface and adheres the second surface 22 of the main body 2 to the ceiling surface with an adhesive, an adhesive tape, or the like during construction. Without being stuck, it can be attached to the ceiling corner of the bathroom. In the present invention, the term “adhesion” refers to sticking in a broad sense. In the present invention, the state in which a member is fixed to a surface such as a wall surface is stably maintained for a long period of time. It is in a state where it is attached but not adhered. The adhesion typically includes adhesion by an adhesive or a pressure-sensitive adhesive, or adhesion that is attached via a pressure-sensitive adhesive tape.
The first surface 21 and the second surface 22 are preferably formed in a flat shape, except for the first protrusion 31 and the second protrusion 32. By forming the 1st surface 21 in flat shape, the adhesion area with the wall surface 91 becomes large, and the bathroom ceiling periphery edge member 1 can be attached firmly. Since the second surface 22 is formed in a flat shape, the contact area with the ceiling surface 92 is increased, and the intrusion of moisture and water vapor can be effectively prevented.
The third surface 23 opposite to the first surface 21 of the main body 2 and the fourth surface 24 opposite to the second surface 22 of the main body 2 are both surfaces exposed to the outside during construction. . The third surface 23 and the fourth surface 24 may be flat or curved. At one end portion of the third surface 23 (the end portion on the second surface side of both end portions of the third surface 23), an extending portion 5 that protrudes on the opposite side of the first surface 21 is formed. Yes.

The extension portion 5 is formed in a substantially triangular shape in cross-sectional view that gradually becomes narrower toward the tip. The extension portion 5 is preferably formed in a shape like a bird's cage so that the tip portion forms an acute angle, and more preferably, the tip portion forms 20 degrees to 50 degrees. Such an extended portion 5 having a substantially triangular shape in cross section is easily deformed, so that the second projecting portion 32 is easily adhered to the ceiling surface.
In addition, the base portion 5a of the extending portion 5 is formed in a curved surface shape or an obtuse inclined surface shape with respect to the third surface 23. Therefore, the extending portion 5 forms a curved surface or an inclined surface and forms the third surface 23. It is connected to. In the illustrated example, the base portion 5 a of the extending portion 5 is curved with respect to the third surface 23.
The protrusion height 5H of the extension part 5 is not particularly limited, but if it is too small, the extension part 5 is difficult to bend and the second protrusion 32 may be difficult to follow the unevenness of the ceiling surface. If it is too large, the width of the second surface 22 becomes relatively large. From this viewpoint, the protrusion height 5H of the extending portion 5 is preferably 0.5 mm to 3 mm, more preferably 0.7 mm to 2.5 mm, and still more preferably 1 mm to 2 mm. In addition, the protrusion height 5H of the extension part 5 means the linear length between the front-end | tip of the extension part 5, and the 3rd surface 23, as shown in FIG.

The intersecting portion of the first surface 21 and the second surface 22 including the ridge line portion 4 may be angular or chamfered. Preferably, the intersecting portion is chamfered, more preferably chamfered into a curved surface. In the illustrated example, the intersection of the first surface 21 and the second surface 22 including the ridge line portion 4 is formed by forming one end of the first surface 21 and one end of the second surface 22 in a curved shape. The curved surface is formed as a whole, and the central portion of the curved surface is the ridge line portion 4. As shown in FIG. 3B, generally, the angle θ formed by the wall surface 91 and the ceiling surface 92 in the ceiling corner 93 of the bathroom is not necessarily a right angle, but an obtuse angle slightly larger than 90 degrees or an acute angle slightly smaller. In addition, there are cases where a right angle portion, an obtuse angle portion, and an acute angle portion are randomly present. In the bathroom ceiling edge member 1 according to the present invention, the intersecting portion of the first surface 21 and the second surface 22 is chamfered into a curved surface, so that the first surface 21 is a wall surface in the chamfered portion. The second surface 22 is in contact with the ceiling surface 92 while being in contact with 91, and in addition to this, the first protrusion 31 and the second protrusion 32 are in contact with the wall surface 91 and the ceiling surface 92. It is possible to effectively prevent water and water vapor from entering the corner portion 93. Further, as shown in FIG. 3B, even when the angle θ is a certain obtuse angle, for example, in the range of more than 90 degrees and 100 degrees, the bathroom ceiling edge member 1 of the present invention has the second protrusions 32 and the second projections. When the two surfaces 22 are in contact with the ceiling surface 92, it is possible to prevent moisture and water vapor from entering.
In addition, the intersection part of the 3rd surface 23 and the 4th surface 24 may be squared, and may be rounded off. In the illustrated example, the intersecting portion of the third surface 23 and the fourth surface 24 is formed in a curved surface like the intersecting portion of the first surface 21 and the second surface 22. Since the intersecting portion of the third surface 23 and the fourth surface 24 is formed in a curved shape, water droplets adhering to the third surface 23 sequentially flow from the intersecting portion to the wall surface 91 through the fourth surface 24. It is possible to prevent water droplets from falling from the edge member 1 around the bathroom ceiling.
The angle α formed by the first surface 21 and the second surface 22 is not particularly limited, but is preferably 80 ° to 100 °, more preferably 85 ° to 95 °, and still more preferably about 90 °. It is.

Although the cross-sectional shape of the main body 2 is not particularly limited, it is preferable that the width 21W of the first surface 21 is substantially rectangular or L-shaped larger than the width 22W of the second surface 22. The cross-sectional view shape of the main body 2 in the illustrated example is a substantially L shape composed of a substantially rectangular portion and a substantially triangular portion (extension portion 5) provided at an end portion thereof. The width 22W of the second surface 22 is the sum of the thickness of the substantially rectangular portion and the protruding height 5H of the extending portion 5.
The bathroom ceiling edge member 1 having the first surface 21 having a relatively large area can be firmly bonded to the wall surface by the first surface 21, and the appearance after construction is also improved. Specifically, the bathroom ceiling edge member 1 can be bonded stably and firmly by bonding the bathroom ceiling edge member 1 along the wall surface at the corner of the ceiling of the bathroom, which is not necessarily a right angle. The bathroom ceiling edge member 1 can be constructed linearly. On the other hand, since it is difficult for the second surface 22 arranged on the ceiling surface to be adhered to the ceiling surface, the adhesive is applied to the second surface 22 or the adhesive tape is applied to the second surface 22 during the construction. It is preferable that the second surface 22 is brought into close contact with the ceiling surface while the second surface 22 is applied to the ceiling surface without performing an adhesive treatment such as. When the width 22W of the second surface 22 that is not bonded to the ceiling surface is larger than the width 21W of the first surface 21 or equal to the width 21W of the first surface 21, the second corner 22 in the region that is not a right angle in the ceiling corner. The two surfaces 22 are easily lifted from the ceiling surface. Therefore, the main body 2 preferably has a shape in which the width 21W of the first surface 21 is larger than the width 22W of the second surface 22.

  In addition, the said cross-sectional view shape is a shape when it cut | disconnects by the plane perpendicular | vertical to the longitudinal direction of the bathroom ceiling surrounding edge member 1 (cut | disconnected by the III-III line of FIG. 1). The width 21W of the first surface 21 is the length of the first surface 21 in a direction orthogonal to the longitudinal direction of the bathroom ceiling edge member 1, and is one end of the first surface 21 as shown in FIG. To the other end. The width 22W of the second surface 22 is the length of the second surface 22 in the direction orthogonal to the longitudinal direction of the bathroom ceiling edge member 1, and is one end of the second surface 22 as shown in FIG. To the other end.

  However, the cross-sectional shape of the main body 2 is not limited to the case where the width of the first surface 21 is larger than the width of the second surface 22, and the width of the second surface 22 may be larger than the width of the first surface 21. (Not shown). Moreover, the main body 2 may be formed in a cross-sectional view shape in which the width of the first surface 21 and the width of the second surface 22 are the same. As the shape in which the width of the first surface 21 and the width of the second surface 22 are the same, when the main body 2 is formed in a substantially square shape in cross section, in a case where it is formed in a substantially square shape in cross section, etc. (Not shown).

The ratio of the width 21W of the first surface 21 and the width 22W of the second surface 22 can be set as appropriate. For example, “the width of the first surface / the width of the second surface” is 1.1 to 6.7. , Preferably, it is 1.5-4, More preferably, it is 2-3.5.
In specific numerical values, the width 21W of the first surface 21 is, for example, 8 mm to 20 mm, preferably 9 mm to 16 mm, and more preferably 10 mm to 14 mm. The width 22W of the second surface 22 is, for example, 3 mm to 7 mm, preferably 4 mm to 6 mm, and more preferably 4 mm to 5 mm. If the width 22W of the second surface 22 is too small, the rigidity of the main body 2 is lowered, and it becomes difficult to linearly attach the bathroom ceiling edge member 1 during construction, and the waterproof effect may be reduced.

The first protrusion 31 protrudes from the other end of the first surface 21. The first protrusion 31 is formed in a substantially triangular shape in cross-sectional view that gradually becomes narrower toward the tip. In addition, the base 31 a of the first protrusion 31 has an inclined surface or curved surface that is obtuse with respect to the first surface 21, and thus the first protrusion 31 has an inclined surface or curved surface on the first surface 21. It is formed continuously. In the illustrated example, the base portion 31 a of the first protrusion 31 is inclined with respect to the first surface 21.
The protrusion height 31H of the first protrusion 31 is not particularly limited. However, if the protrusion height 31H is too small, when the first surface 21 is bonded to the wall surface of the bathroom using an adhesive or an adhesive tape, There is a possibility that the end portion cannot be sufficiently concealed. If the end portion is too large, the first surface 21 adhered to the wall surface may be lifted from the wall surface over time due to the elastic restoring force of the first protrusion 31. From this viewpoint, the protrusion height 31H of the first protrusion 31 is preferably 0.4 mm to 1 mm, more preferably 0.5 mm to 0.8 mm, and still more preferably 0.5 mm to 0.7 mm. The protrusion height 31H of the first protrusion 31 refers to the linear length between the tip of the first protrusion 31 and the first surface 21, as shown in FIG.
In addition, the width 31W of the first protrusion 31 is not particularly limited, but if it is too large, the proportion of the flat portion of the first surface 21 becomes relatively small, and a sufficient adhesion area to the wall surface may not be secured. If it is too small, there is a risk that the function of the protrusion will not be sufficiently achieved. From this viewpoint, the width 31W of the first protrusion 31 is preferably 0.6 mm to 1.8 mm, more preferably 0.7 mm to 1.5 mm, and still more preferably 0.8 mm to 1. .2 mm. The width 31W of the first protrusion 31 refers to the maximum width of the first protrusion 31 as shown in FIG.

The second protrusion 32 protrudes from the other end of the second surface 22. In the present embodiment in which the extending portion 5 protrudes from the third surface 23 and the other end of the second surface 22 extends to the side opposite to the first surface 21, the second protruding portion 32 is The protrusion 5 protrudes from the extension 5 in a direction substantially perpendicular to the protruding direction of the extension 5.
The second protrusion 32 is formed in a substantially triangular shape in cross-sectional view that gradually becomes narrower toward the tip. Further, the base 32 a of the second protrusion 32 has an inclined surface or curved surface that is obtuse with respect to the second surface 22, and therefore the second protrusion 32 is inclined or curved on the second surface 22. It is formed continuously. In the illustrated example, the base portion 32 a of the second protrusion 32 is inclined with respect to the second surface 22.
The protrusion height 32H of the second protrusion 32 is not particularly limited, but if it is too small, it does not adhere to the ceiling surface, and there is a risk of creating a gap between it and the ceiling surface. The closely attached second projecting portion 32 undulates and the appearance after construction is deteriorated. From this viewpoint, the protrusion height 32H of the second protrusion 32 is preferably 0.3 mm to 1.5 mm, more preferably 0.4 mm to 0.8 mm, and still more preferably 0.4 mm to 0.6 mm. In addition, the protrusion height 32H of the second protrusion 32 refers to the linear length between the tip of the second protrusion 32 and the second surface 22 as shown in FIG.
Further, the width 32W of the second protrusion 32 is not particularly limited, but if it is too large, the proportion of the flat portion of the second surface 22 is relatively small, and if it is too small, the function of the protrusion is reduced. There is a risk that it will not play well. From this point of view, the width 32W of the second protrusion 32 is preferably 0.5 mm to 1.7 mm, more preferably 0.7 mm to 1.5 mm, and still more preferably 0.9 mm to 1. .2 mm. The width 32W of the second protrusion 32 refers to the maximum width of the second protrusion 32 as shown in FIG.

The bathroom ceiling edge member 1 according to the present invention is used by being attached to the ceiling corner of the bathroom.
Specifically, the bathroom ceiling edge member 1 is attached across the wall surface and the ceiling surface at the ceiling corner of the bathroom.
The construction method of attaching the bathroom ceiling edge member 1 to the ceiling corner is as follows. First, the bathroom ceiling edge member 1 is cut into an appropriate length using a cutter or the like, and the bathroom ceiling edge member 1 Adhesive tape is applied to one surface 21 or an adhesive is applied. It is preferable to use a pressure-sensitive adhesive tape because the pressure-sensitive adhesive tape does not sag compared with an adhesive and is easy to handle and does not need to be cured. Moreover, the construction time in the field can be further shortened by sticking the adhesive tape to the 1st surface 21 previously.
Next, after positioning the second surface 22 of the bathroom ceiling edge member 1 toward the ceiling surface 92 of the bathroom 9 and applying the second protrusion 32 to the ceiling surface 92, the first surface 21 is adhered to the adhesive tape 6 or It adheres to the wall surface 91 through an adhesive. At this time, by pressing the bathroom ceiling edge member 1 from the third surface 23 side toward the wall surface and the ceiling surface, the first surface 21 adheres to the wall surface 91 without a gap and the first protrusion having flexibility. The portion 31 and the second protrusion 32 are deformed, the second protrusion 32 is in close contact with the ceiling surface 92, and the first protrusion 31 is in close contact with the wall surface 91 (see FIGS. 4 and 5). The second surface 22 is in contact with the ceiling surface 92 partially or entirely.
For example, when an adhesive tape having a thickness of 0.5 to 0.8 times the protruding height 31H of the first protrusion 31 is used, the adhesive tape comes before positioning because the first protrusion 31 hits the wall surface 91. Can be prevented from adhering to the wall surface, can be easily positioned, and can be easily adhered after pressing in the direction of the wall surface. For example, when the protrusion height 31H of the first protrusion 31 is 0.6 mm, the workability is improved as described above by using an adhesive tape having a thickness of 0.4 mm.
In addition, when adhering the bathroom ceiling edge member 1 to the wall surface 91, either an adhesive tape or an adhesive may be used, but an adhesive tape and an adhesive may be used in combination as necessary.

  It is preferable that the said adhesive tape 6 is a double-sided adhesive tape which has an adhesive layer on both surfaces. When the adhesive tape 6 is used, it is preferable to use an adhesive tape whose thickness is the same as the protruding height 31H of the first protruding portion 31 or smaller than the protruding height 31H of the first protruding portion 31. By using the adhesive tape 6 having such a thickness, when the first surface 21 is bonded to the wall surface 91, the first protrusion 31 is appropriately deformed following the unevenness of the wall surface 91, and the tip of the first protrusion 31. Comes into close contact with the wall surface 91.

The bathroom ceiling edge member 1 of the present invention may be used in a newly built bathroom or in a bathroom at the time of renovation.
For example, as a method for renovating a bathroom, there is a method of sticking a sheet or panel on the ceiling surface and wall surface of the bathroom. In particular, when the bathroom is repaired by attaching the sheet to the ceiling surface and the wall surface, by using the bathroom ceiling peripheral member 1 of the present invention, it is possible to easily perform blinding and waterproofing of the joint portion of the sheet. Therefore, the bathroom ceiling edge member 1 of the present invention can be suitably used for bathroom repair.
4 and 5 show a state where the bathroom ceiling edge member 1 of the present invention is attached to such a modified bathroom.
The ceiling surface 92 and the wall surface 91 of the modified bathroom are composed of, for example, surfaces of a new ceiling sheet material 72 and a wall sheet material 71 attached to the ceiling base surface 82 and the wall base surface 81.
The connection structure in which the bathroom ceiling edge member 1 is attached to the ceiling corner of the modified bathroom includes a ceiling surface 92 constituted by the ceiling sheet material 72, a wall surface 91 constituted by the wall sheet material 71, and the ceiling surface. A bathroom 9 having a ceiling corner 93 between the wall 92 and the wall 91, and a bathroom ceiling edge member 1 that spans the ceiling surface 92 and the wall 91 and hides the ceiling corner 93. The first surface 21 of the bathroom ceiling edge member 1 is bonded to the wall surface 91 via at least one of the adhesive tape 6 and the adhesive, and a part or the whole of the first protrusion 31 is deformed. The second protrusion 32 is partly or entirely deformed and is in close contact with the ceiling surface 92.
In addition, as described in Patent Document 1, in a bathroom such as a unit bath, there is a case where a recessed portion is provided at a ceiling entering corner, and a ceiling edge member is inserted into the recessed portion. In refurbishing a bathroom having such a structure, the existing ceiling edge member 1 can be used without using the existing ceiling edge member. In this case, if necessary, a resin foam is inserted into the recessed portion to fill the gap, and a sheet or panel is attached to the wall or ceiling surface of the modified bathroom. Waterproofing can be performed by bonding the peripheral edge member 1, and its construction is also easy.

  Since the bathroom ceiling edge member 1 of the present invention has a relatively simple structure, the bathroom ceiling edge member 1 can be provided at low cost, and can be easily cut with a cutting tool such as a cutter, so that it can be easily constructed. Moreover, since the bathroom ceiling edge member 1 of this invention is a structure attached along a wall surface and a ceiling surface, it is excellent in versatility and can complete construction in a comparatively short time. Furthermore, since the 1st projection part 31 and the 2nd projection part 32 deform | transform suitably, and absorb the unevenness | corrugation of a wall surface and a ceiling surface, dew condensation water generate | occur | produces in a humid bathroom, or water, such as a shower, splashes directly. Even if there is, it is possible to prevent moisture and water vapor from entering the ceiling corner. Furthermore, by setting the width of the first surface 21 to be larger than the width of the second surface, the bathroom ceiling-around edge member 1 after construction becomes straight, and the connection structure of the ceiling corner having a beautiful finished appearance Can be built.

  The bathroom ceiling edge member of the present invention is not limited to the first embodiment, and can be variously changed within the range intended by the present invention. Hereinafter, although other embodiment of this invention is described, description is abbreviate | omitted about the structure, effect, and usage method similar to the said 1st Embodiment, and a term and a code | symbol are used as it is.

[Second Embodiment]
In the first embodiment, the third surface 23 is formed in a flat shape parallel to the first surface 21, but the third surface 23 is formed in a flat surface shape inclined with respect to the first surface 21. May be. Further, the fourth surface 24 may also be formed as a flat surface inclined with respect to the second surface 22.
FIG. 6 shows the bathroom ceiling edge member 1 in which the third surface 23 is inclined with respect to the first surface 21. In this case, the third surface 23 is inclined at an acute angle with respect to the second surface 22. The bathroom ceiling edge member 1 in this form is preferable because water drops are transmitted from the third surface 23 to the fourth surface 24 and smoothly flow to the wall surface. In particular, as shown in the illustrated example, the above-described effect can be remarkably achieved by forming the intersecting portion of the third surface 23 and the fourth surface 24 in a curved shape.
Further, instead of or in addition to the inclined third surface 23, the fourth surface 24 is formed so as to incline at an acute angle with respect to the first surface 21 ( (Not shown), the effect can be more remarkably achieved.

[Third Embodiment]
In the said 1st Embodiment, although the extension part 5 which protrudes on the opposite side to the 1st surface 21 is provided, for example, as shown in FIG. 7, the bathroom ceiling edge which is not provided with the extension part The member 1 may be used. The bathroom ceiling edge member 1 in this form is not provided with an extending portion, and therefore, after the construction, a step due to the extending portion does not occur at the boundary between the third surface 23 and the ceiling surface 92, and the ceiling entrance It can be set as the finishing appearance in which the bathroom ceiling periphery edge member 1 is not emphasized in the corner.

[Fourth Embodiment]
In the first embodiment, the first projecting portion 31 is formed in a substantially triangular shape in cross section, but may be formed in a substantially semicircular arc shape as shown in FIG. 8, for example. Similarly, the second protrusion 32 may be formed in a substantially semicircular arc shape. Even when the first protrusion 31 and the second protrusion 32 are formed in a substantially semicircular arc shape as described above, the first protrusion 31 and the second protrusion 32 are gradually narrowed toward the tip. The 2nd projection part 32 tends to stick to a wall surface and a ceiling surface. Moreover, by forming it in a substantially semicircular arc shape as in this embodiment, there are slight steps between the first protrusion 31 and the wall surface 91 and between the second protrusion 32 and the ceiling surface 92 after construction. Occurs. As a result, a shadow is generated by lighting on the constructed bathroom ceiling surrounding edge member 1 so that the surrounding edge member 1 can be viewed three-dimensionally, and a design accent can be imparted to the finished appearance of the ceiling corner.
