Description

  The present invention relates to a wall panel constituting a wall surface of a unit room such as a bathroom, and a connection structure between the wall panels of the unit room.

  The unit room is a room-type unit composed of floors, walls, and ceilings combined with water supply and drainage facilities and electrical facilities. Among them, a plate-like panel that is strong enough to maintain a flat surface can be connected. The panel type that constitutes the wall surface is widely used in unit bathrooms, unit shower rooms, unit toilet rooms, and the like.

  The wall surface of the unit room by this panel system is mainly constructed with a vertical wall panel standing up to the ceiling surface from the floor surface on the wall panel mounting part formed at the outer edge of the floor. is there. The wall panel of this structure has a height of 2000 mm or more, and the weight increases as the panel width increases. Therefore, the panel width cannot be increased considering the transportation and assembly work. One wall surface is composed of a plurality of wall panels.

  At this time, it is prevented that a level | step difference arises between wall panels, or a panel long in a height direction bends in an out-of-plane direction (a vertical direction center part protrudes to an indoor side, or retreats to an outdoor side). In order to prevent this, for example, as shown in FIG. 16, it is necessary to support the column 102 upright from the floor at the connection portion of the wall panels 101.

  Therefore, the wall panel 101 is pushed out indoors so as to secure a space S in which the support column 102 is erected between the wall surface 103 and the wall panel 101 of the building body, and the space in the eaves unit room is narrowed. In particular, when renovating an existing building, it is often necessary to hit the existing wall to secure the necessary space in order to provide a standardized unit room at a predetermined location. Not only will the construction period be extended due to the increase in construction costs, but also the disposal costs for scrapped construction materials such as garlic will increase. In addition, the noise and dust generated may cause trouble in the vicinity.

  Therefore, various methods for reducing or eliminating the struts have been studied in order to minimize the gap between the building wall surface and the unit room wall surface. Among them, a wall panel having a horizontally stacked structure has been proposed (see, for example, Patent Document 1). This is a connection structure in which a protrusion is provided on one side end of a wall panel made of an extruded cement board and a concave groove is provided on the other side end, and the two edges of the concave groove are both fitted to the other wall panel. It has a shape that comes into contact with the root of the ridge. This structure can be spanned by a single panel in the lateral direction from the wall end to the other end, and since there is no risk of bending because the upper and lower panels are fitted, A strut is unnecessary, and it can be said that it is a rational structure.

  However, as shown in FIG. 17 (a), when the molding accuracy of the ridges and / or grooves is poor, or as shown in FIG. In this case, a gap G is generated between the upper end of the lower wall panel and the lower end of the upper wall panel, causing problems such as deterioration in designability, deterioration in watertight reliability, and deterioration in cleanliness due to dirt entering the gap. Will occur.

  In particular, when foreign matter F is caught in the fitting portion on the outdoor side of the wall panel, the worker's hand inside the room cannot reach, so in order to remove foreign matter F, the wall panel being assembled must be removed once. Therefore, there is a risk that the efficiency of the assembly work will be significantly deteriorated.

  In order to solve this problem, it is conceivable to fill with watertight material such as silicon coking, but this increases the number of assembly operations, and there is a difference in the finish due to variations in the skill level of the assembly operator. Will cause new problems such as loss of cleanliness. Alternatively, it is conceivable to use special parts or jigs for forcibly pulling the wall panels together, but this still has the problem of increasing the number of assembling steps and costs.

On the other hand, in order to solve the problem of the gap between the wall surface of the building and the wall surface of the unit room, it is necessary to consider not only the method of reducing or eliminating the column, but also the direction of reducing the thickness of the wall panel itself. However, since the extrusion-molded cement board adopted in Patent Document 1 has a certain thickness, there is room for improvement. Moreover, also in terms of cost, the cost is higher than that of a steel sheet with a backing material that is often used for vertical wall panels. However, the wall panel formed by sticking the backing material to this decorative steel sheet is thin, strong, and inexpensive, but it is difficult to achieve accuracy, so ensuring the accuracy of the fitting part is essential. It could not be applied to horizontal stacked structures.

  INDUSTRIAL APPLICABILITY The present invention has an effect of obtaining a unit room wall panel having a design property, watertight reliability, and cleanliness, and its connection structure.

  DESCRIPTION OF EMBODIMENTS Embodiments of a unit room wall panel and its connection structure according to the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an overall outline of a unit room 1 having a wall panel according to the present invention as a constituent element. The unit room 1 shown in the present embodiment includes a floor 2, a wall 3, corner posts 4, ceiling panels and doorways (not shown), and forms a space having a certain size.

  The floor 2 is constituted by a building floor or a waterproof pan, and a wall panel placement portion 2 a on which the wall panel 10 constituting the wall 3 can be placed is formed on the four circumferences of the floor 2.

  The corner columns 4 are erected at the four corners of the floor and hold the wall panels 10 and 10A in the erected state.

  The wall 3 is composed of a lower wall panel 10 erected on the wall panel placement portion 2a and an upper wall panel 10A placed thereon. The wall panels 10 and 10 </ b> A are joined to a tongue-and-groove (a method of joining plates that are carved with one convex and the other concave), and placed on the wall panel placement portion 2 a provided on the outer edge of the floor 2. And is installed between the upright corner posts 4 and 4. Therefore, it is not necessary to provide a column in the middle of the wall 3. In the present embodiment, the case of two steps will be described as an example. However, when the ceiling height is high, the wall 3 may be configured by stacking three or more wall panels.

  For example, in a unit bath which is a form of a unit room, the size is approximately 1600 × length 1600 × height 2000 mm. In this case, in the conventional vertical wall panel, the length of one panel is about 2000 mm. However, since the wall panel having a horizontally stacked structure according to the present invention has a length of around 1600 mm, it can be easily swung during transportation or assembly.

  The wall panel 10 installed in the lower stage among the wall panels constituting the wall 3 of the unit room 1, as shown in FIG. 2, faces the core material 12, the surface material 11 facing the indoor side, and the outdoor side. The back material 13 is formed by adhering with an adhesive. For example, a decorative steel plate is used for the surface material 11 and the back material 13, and a plaster board, a cement plate, a calcium silicate plate, a foamed resin plate, or the like is used for the core material 12, for example. With this configuration, the thickness of the wall panel 10 itself is suppressed to about 12 mm, is thinner than an extruded cement board having a thickness of about 30 mm, and the weight is much lighter than that of an extruded cement board. It is easy to handle in assembly. And it can manufacture cheaper than an extrusion-molded cement board.

  As shown in FIG. 2 (c), the upper end of the surface material 11 is bent toward the back surface to form a ridge 14 that is used for tongue and groove joining. As for this protruding item | line 14, the top part 14b is standingly arranged in the center of the indoor side bottom part 14a and the outdoor side bottom part 14c. Here, the indoor side bottom part 14a and the outdoor side bottom part 14c are formed at the same height.

  On the other hand, as shown in FIG. 2D, the lower end of the surface material 11 is bent to the back side to form the concave strip 15. The concave groove 15 is provided with an indoor-side top 15a and an outdoor-side top 15c erected across the bottom 15b located in the center of the wall panel 10 in the thickness direction. The distance from the indoor-side top 15a to the bottom 15b Is longer than the distance from the outdoor top 15c to the bottom 15b, that is, the indoor top 15a is formed relatively higher.

  On the other hand, as shown in FIG. 2 (e), both side ends of the surface material are simply bent at right angles to the back surface side to protect the end portions of the core material 12.

  In addition, on the back surface of the wall panel 10, a retaining hole 12 a shown in FIG. The wall panel 10 is erected by the latching hole 12a being latched by a pin 30d, which will be described later, projecting from the column 4.

  Of the wall panels constituting the wall 3 of the unit room 1, the wall panel 10 </ b> A installed at the upper stage has basically the same configuration as the wall panel 10, but its upper end is simply bent to the back side. This is different from the wall panel 10 (see FIG. 6).

  The corner column 4 is provided at the corner of the exit corner of the unit room 1 and has a function of supporting the load of the wall 3 and arranging the entrance and exit between the surfaces of the wall panels. This corner support | pillar 4 is comprised from the corner joint 20 located in a room inner side, and the corner backup material 30 located in a wall panel back surface side.

  As shown in FIG. 3, the corner joint 20 includes a joint body 20a, a soft portion 20b, and a support portion 20c. The joint body 20a is formed by molding a hard plastic such as ABS resin into a long and narrow triangular prism shape, covering the abutting end of the wall panel 10 and the other wall panel 10 orthogonal to each other, and has watertightness and design. It is what raises.

  The soft portion 20b is a flexible member made of, for example, an olefin-based elastomer. When the corner joint 20 is pressed against the wall panel 10, the soft portion 20b is deformed and pressure-bonded to the wall panel 10 to improve water tightness.

  The support part 20c is formed in a rod body having a substantially Y-shaped cross section, for example, by bending a stainless steel plate into two. A plurality of system insertion pieces 20d are projected from the support portion 20c at regular intervals. The wall panel 10 is sandwiched between the corner joint 20 and the corner backup material 30 by this system entry piece 20d being inserted into a later-described slit 30d formed in the corner backup material 30.

  As shown in FIG. 4 (a), the corner backup material 30 is elongated, for example, a galvanized steel sheet or the like that is bent, and its short-side cross-section is as shown in FIG. 4 (c). The corner joint hooking portion 30a and wall panel receiving portions 30b and 30b bent at an angle of 45 degrees at both ends of the corner joint hooking portion 30a.

  In the corner joint engaging portion 30a, a plurality of slits 30d into which the system entrance pieces 20d of the corner joint 20 are inserted are formed at predetermined intervals. On the other hand, on the wall panel receiving portion 30b, as shown in FIG. 4 (b), a pin inserted into the retaining hole 12a at a position where the retaining holes 12a provided in the upper and lower wall panels face each other. 30d is projected. In addition, a bolt hole 30e is provided in the vicinity of the lower end of the corner joint engaging portion 30a for standing the corner backup material 30 on the wall panel placement portion 2a of the floor 2 via an angle piece or the like.

  The unit room 1 according to the present embodiment is configured as described above, and the mounting order of the wall panels will be described below with reference to the flowchart shown in FIG.

  First, the corner backup material 30 is erected on the floor 2 such as a building floor or a waterproof pan (step S1). This standing is performed, for example, by fixing an angle piece on the floor 2 and screwing a bolt into a bolt hole drilled in the angle piece and a bolt hole 30e of the corner backup material 30.

  Next, the retaining hole 12a of the lower wall panel 10 is fitted over the pin 30d of the corner backup material 30 that is erected, and the wall panel 10 is erected (step S2). If this unit room is required to be watertight, the wall panel 10 is placed after the watertight material 50 is laid on the wall panel placement portion 2a as shown in FIG. 6 (b).

  Subsequently, after the concave groove 15A at the lower end of the upper wall panel 10A is fitted to the ridge 14 at the upper end of the lower wall panel 10 and joined by tongue and groove, the locking hole 12a of the upper wall panel 10A is The wall panel 10A is erected by being externally fitted to the pins 30d of the erected corner backup material 30 (step S3).

  As a result, as shown in FIG. 6B, even if the indoor side bottom portion 14a and the indoor side top portion 15a come into contact with each other, the outdoor side bottom portion 14c and the outdoor side top portion 15c do not come into contact with each other. G is formed. Therefore, even if a foreign object is caught between the outdoor bottom part 14c and the outdoor top part 15c at the time of assembly, the foreign substance does not hinder the contact between the indoor bottom part 14a and the indoor top part 15a.

  A concave groove 15 is formed at the lower end of the lower wall panel 10 in the same manner as the lower end of the upper wall panel 10A. Since the groove 14 and the concave groove 15 are always formed at the other side end, it is not necessary to divide the types of the wall panel into those for the upper stage and those for the lower stage, and management becomes easy.

  On the other hand, the upper end of the upper wall panel 10 </ b> A is formed in a shape that is obtained by bending the decorative steel plate 11 once, so that an advantage of easy processing can be obtained. Thus, it can also form in arbitrary shapes other than the side end actually joined to a toothpaste.

  Subsequently, as shown in FIG. 7, the system joint piece 20d of the corner joint 20 is inserted into the slit 30c of the corner backup material 30, and the corner joint 20 is attached (step S4). As a result, as shown in FIG. 8, the wall panels 10, 10 </ b> A are sandwiched between the corner backup material 30 and the corner joint 20, and the retaining holes 12 a of the wall panels 10, 10 </ b> A drop off from the pins 30 d of the corner backup material 30. Without being fixed.

  At this time, the soft part 20b on the back side of the corner joint 20 is deformed by being pressed between the wall panels 10 and 10A and the joint body 20a, and is pressure-bonded to the wall panels 10 and 10A to improve water tightness. Further, when the wall panels 10, 10 </ b> A are pressed, no step is generated between the upper wall panel 10 </ b> A and the lower wall panel 10.

  The soft portion 20b is not limited to the shape shown in the present embodiment as long as it has such a function. For example, in this embodiment, two rod-shaped bodies having a triangular cross section are provided on the left and right sides of the joint body 20a, respectively. However, when such a high watertightness is not required, as shown in FIG. It is good only as a book. Moreover, as shown in FIG.9 (b), you may attach to the front-end | tip of the joint main body 20a as a fin-like soft material 20b1. Or as shown in FIG.9 (c), it is also possible to stick the foam packing 20b2 to the whole part contact | abutted to the wall panels 10 and 10A of the joint main body 20a.

  As described above, the mounting of the wall panels 10 and 10A does not require a process such as screwing or bolting, thereby reducing the number of man-hours, shortening the work period, and thus reducing the cost.

  If the ceiling panel 40 is placed on the wall 3 thus erected (step S5), the outer frame of the unit room is completed. For example, as shown in FIG. 6B, the ceiling panel 40 is attached by fitting the end of the ceiling panel 40 into the fitting recess 41 of the connection piece 41 and the other fitting recess of the connection piece 41. 41b is fitted to the upper end of the wall panel 10A.

  The gist of the present invention is that, as described above, in the wall panel joint structure of a unit room, the top portion located on the indoor side of the one side end of the first wall panel and the one side end facing the second wall panel. While the top part located in the indoor side is contact | abutted, there exists in the clearance gap between the top parts located in the outdoor side of the said both wall panel. Therefore, the shape of the tongue and groove is not limited to that according to the above-described embodiment. Hereinafter, some modified examples of the shape of the tongue and groove will be described.

  In the first modification shown in FIG. 10 (a), the concave groove 15 formed at the lower end of the upper wall panel 10C has the indoor side top portion 15a and the outdoor side top portion 15c formed at the same height. The

  On the other hand, the ridges 14 formed on the upper end of the lower wall panel 10B are such that the distance from the indoor bottom 14a to the top 14b is smaller than the distance from the outdoor bottom 14c to the top 14b. The inner bottom portion 14a is formed to be relatively high.

  As a result, as shown in FIG. 10 (b), even if the indoor side bottom portion 14a and the indoor side top portion 15a come into contact with each other after assembling and joining, the outdoor side bottom portion 14c and the outdoor side top portion 15c are A gap G is formed without contact. Therefore, even if a foreign object is caught between the outdoor bottom part 14c and the outdoor top part 15c at the time of assembly, the foreign substance does not hinder the contact between the indoor bottom part 14a and the indoor top part 15a.

  In the second modification shown in FIG. 11 (a), the groove 15 at the lower end of the upper wall panel 10D basically extends from the indoor top 15a to the bottom as in the present embodiment. The distance to 15b is longer than the distance from the outdoor top 15c to the bottom 15b, that is, the indoor top 15a is formed relatively higher, but the indoor top 15a faces the room. The difference is that the height decreases from the front surface side to the bottom portion 15b, that is, the inclined surface 15d is provided with a gradient.

  Thus, the upper wall panel 10D and the lower wall panel 10 come into contact only on the surface side of the indoor side top portion 15a and the indoor side bottom portion 14a, and the same effects as those shown in this embodiment are obtained. In addition, even when a foreign object is caught between the indoor side top portion 15a and the indoor side bottom portion 14a, the effect that the gap G is not generated can be obtained if it is small.

  The third modification shown in FIG. 12A is basically similar to the one shown in the first modification, in which the ridges 14 on the upper end of the lower wall panel 10E are connected to the indoor bottom 14a. The distance to the top portion 14b is smaller than the distance from the outdoor bottom portion 14c to the top portion 14b, that is, the indoor side bottom portion 14a is formed relatively higher. The difference is that the height decreases from the surface side to the top portion 14b, that is, the inclined surface 14d is provided with a gradient. Also in this configuration, the same effect as that of the second modification can be obtained.

  In the fourth modification shown in FIG. 13A, unlike the example described so far, a thin and flexible watertight material 16 is sandwiched between the groove 15 and the ridge 14. Thereby, it can prevent more reliably that the water flooded indoors leaks outside from this tongue-and-groove junction part. Therefore, it is particularly effective when the unit room is used as a unit bathroom or a unit shower room.

  The fifth modified example shown in FIG. 14A is configured to further develop the case using the watertight material shown in the fourth modified example and to positively show the watertight material as the cosmetic mall 17. is there. The decorative molding 17 is made of an elastic material such as an elastomer, and the portion sandwiched between the concave groove 15 and the convex strip 14 is formed into a shape that fits them, while the visible portion swells indoors. As it comes out, it expands along the surface of the wall panels 10, 10A.

  As a result, the tongue-and-groove joint is completely invisible. For example, even if the width of the joint portion is different between the left and right of the wall panel, it is covered by the expanded portion of the decorative molding 17, so that the product Errors and construction errors can be absorbed. In addition, since the lower wall panel and the upper wall panel are clearly distinguished from each other, a new design can be given when the waist portion of the wall surface has a design different from the upper portion.

  Further, according to the gist of the present invention, the joining structure is not limited to the tongue-and-peel joining, but the phase stacking joint (when joining the plate members in the width direction, the wood ends of the two plate members to be joined are half of the plate thickness. It is also possible to cut out each piece and join them. For example, as shown in FIG. 16, the top 14b of the ridge 14 formed on one side end of the wall panel 10F and located on the indoor side, and the ridge on one side end of the wall panel 10G facing the ridge 14 are provided. 14 is in contact with a protruding strip receiving portion 15e located on the indoor side formed in a shape that engages with the protruding portion 14, and the protruding strip receiving portion 15e formed on the outdoor side of the wall panel 10F and the outdoor side of the wall panel 10G. A gap G is provided between the top 14b of the ridge 14 formed in the above.

  Since the gap G is provided on the outdoor side in this way, even if a foreign object is sandwiched between the top 14b of the protruding ridge on the outdoor side and the protruding strip receiving part 15e during the assembly by the splicing joint, Contact between the indoor-side top portion 14b and the convex strip receiving portion 15e is not hindered.

  The embodiments described above are for illustrative purposes and do not limit the scope of the invention. Accordingly, those skilled in the art can employ embodiments in which each or all of these elements are replaced by equivalents thereof, and these embodiments are also included in the scope of the present invention.

  For example, in the present embodiment, the horizontal stacked structure has been described as an example. However, the present invention is not limited to this, and the wall panel of the vertical type, for example, is rigidly connected to the floor under the foot, and In the case where the span intermediate strut can be omitted by, for example, being rigidly joined to the ceiling at the top, it can be adopted.

  Further, the unit room is not limited to a unit bathroom, a unit shower room, a unit toilet room, or the like, but the top portion located on the indoor side at one side end of the first wall panel and the opposite side of the second wall panel A storage room or a trunk room may be used as long as a gap is provided between the tops located on the outer sides of the both wall panels while the tops located on the indoor side of the ends are in contact with each other. .
