Description

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

  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.

  In the unit bathroom which is one form of this unit room, as shown in FIG. 16, the wall panel 100 is constituted by an extrusion-molded cement board without a reinforcing frame, and a concave groove 100a is formed on the wooden end surface of the wall panel 100. A wall panel coupling mechanism for coupling and fixing both wall panels 100 and 100 by interposing a cross-shaped vertical joint 101 across the entire height of the wood end face in a concave groove 100a between both wall panels to be formed and joined has been proposed. (For example, refer to Patent Document 1). And this wall panel coupling | bonding mechanism provides the reinforcement convex part 100b in the tree end surface of the right and left wall panel 100,100 couple | bonded, and couple | bonds a right and left wall panel with the restraint metal fitting 102 engaged with this reinforcement convex part 100b.

  According to this wall panel coupling mechanism, the trouble of adhering the reinforcing frame to the wall panel can be saved, and it is not necessary to provide a screw hole or the like for joining in the reinforcing frame. Therefore, it is not necessary to configure various parts provided with various screw holes. According to this wall panel coupling mechanism, it is not necessary to engage and fix the left and right wall panels with screws or an adhesive as in the prior art. Furthermore, if the vertical joint is formed of an elastic body, it serves as a joint material, and the work of injecting the joint material becomes unnecessary.

  However, in this wall panel coupling mechanism, as shown in FIG. 17A, when the molding accuracy of the recessed groove 100a is poor, or as shown in FIG. When a gap is bitten, a gap G is generated between the two wall panels 100, 100, and there are problems such as a decrease in designability, a decrease in watertight reliability, and a decrease in cleanliness due to dirt entering the gap. appear. Such a problem also occurs when the molding accuracy of the joint 101 is poor, as shown in FIG.

  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 such a unit room, there is a demand for reducing the thickness of the wall panel in order to make the indoor floor area as large as possible. However, since the extrusion-molded cement board adopted in Patent Document 1 has a certain thickness, there is room for improvement. In addition, the cost is higher than that of a steel sheet with a backing material that is often used for 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 was not applicable to the structure as described above.

It is also possible to do.

  According to the wall panel of the unit room and the connection structure thereof according to the present invention, it is possible to provide the wall panel of the unit room, the connection structure, and the connection material that can be assembled inexpensively and easily.

  INDUSTRIAL APPLICABILITY The present invention has an effect of obtaining a unit room wall panel having a design property, water-tight reliability, and a clean feeling, its connection structure, and connection material.

  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 10A are mounted on the wall panel mounting portion 2a provided on the outer edge of the floor 2 by being joined to a tongue and groove (a method of bonding plates that are carved with one convex and the other concave). , 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. 2C, the upper end and the lower end of the surface material 11 are bent to the back side to form a concave groove 15. The concave groove 15 is constituted by an indoor side top portion 15a and an outdoor side top portion 15c with a bottom portion 15b located at the center in the thickness direction of the wall panel interposed therebetween. Here, the indoor side top portion 15a and the outdoor side top portion 15c are defined as Are formed at the same height.

  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 ends 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.

  On the other hand, the wall panel 10A installed on the upper stage among the wall panels constituting the wall 3 of the unit room 1 is basically formed in the same manner as the wall panel 10 as shown in FIG. It is different in that the ridge 14 is formed by being bent to the back side. As shown in FIG. 3C, the ridge 14 is configured such that a top portion 14b is erected at the center of the indoor side bottom portion 14a and the outdoor side bottom portion 14c. Here, the indoor side bottom part 14a and the outdoor side bottom part 14c are formed at the same height.

  Similar to the wall panel 10, the lower end of the surface material 11 is bent to the back side to form a groove 15A. As shown in FIG. 3 (d), the groove 15A has an indoor top portion 15a. The concave groove 15 of the wall panel 10 is such that the distance from the bottom 15b 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. Is different.

  A connecting member 18 is interposed between the wall panels 10 and 10A. The connecting member 18 is composed of a fitting portion 18b, an indoor ridge 18a, and an outdoor ridge 18c using an elastic material such as an elastomer. The fitting portion 18b is formed in such a shape that the upper end fits into the groove 15A located at the lower end of the upper wall panel 10A and the lower end fits into the groove 15 located at the upper end of the lower wall panel 10A. (See FIG. 7). The indoor ridge 18a protrudes from the middle of the fitting portion in the height direction toward the indoor side of the unit room 1, and the outdoor ridge 18c protrudes outward from the room.

  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. 4, 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. 5 (a), the corner backup material 30 is elongated, for example, a galvanized steel plate or the like that is bent. 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. 5 (b), a pin fitted into the latching hole 12a at a position where the latching 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 the unit room is required to have water tightness, the wall panel 10 is placed after the water tight member 50 is laid on the wall panel placing portion 2a as shown in FIG. 7B.

  Subsequently, the lower part of the fitting portion 18b of the connecting member 18 is fitted into the groove 15 located at the upper end of the wall panel 10, and the connecting member 18 is placed on the wall panel 10 (step S3).

  Then, the locking hole 12a of the upper wall panel 10A is externally fitted to the pin 30d of the corner backup material 30 that is erected, and the wall panel 10A is erected (step S4). At this time, the concave groove 15A at the lower end of the upper wall panel 10A is externally fitted to the upper portion of the fitting portion 18b of the connecting member 18. As described above, the connecting member 18 prevents water leaked in the room from leaking from the wall panel joint to the outside, and also serves as an alignment guide when the upper wall panel 10A is suspended.

  As a result, as shown in FIG. 7B, even if the indoor side top portions 15a, 15a of the wall panels 10, 10A abut against the indoor side protrusions 18a of the connecting member 18, the outdoor top portion of the upper wall panel 10A. 15c and the outdoor protrusion 18c of the connecting member 18 do not contact each other, and a gap G is formed between them. Therefore, even if foreign matter is caught between the outdoor top portion 15c of the upper wall panel 10A and the outdoor protrusion 18c of the connecting member 18 at the outdoor side during assembly, the foreign matter causes the indoor top portion 15a of the wall panel 10A. And the contact of the indoor ridge 18a of the connecting member 18 is not hindered.

  Then, as shown in FIG. 8, 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 S5). As a result, as shown in FIG. 9, the wall panels 10 and 10 </ b> A are sandwiched between the corner backup material 30 and the corner joint 20, and the latching holes 12 a of the wall panels 10 and 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 high water tightness is not required, as shown in FIG. It is good only as a book. Further, as shown in FIG. 5B, the fin body 20a may be attached to the tip of the joint body 20a. Alternatively, as shown in FIG. 5C, the foam packing 20b2 can be attached to the entire portion of the joint body 20a that contacts the wall panels 10 and 10A.

  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 S6), the outer frame of the unit room is completed. For example, as shown in FIG. 7B, 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 first wall panel having the first concave groove on one side end and the side end opposed to the first concave groove. And a second wall panel having a second groove and a fitting that is interposed between the first and second wall panels and that fits into the first and second grooves. And a connecting member having a protrusion projecting from the fitting portion, and the protrusion is in contact with and sandwiched between the top portions of the first and second concave grooves located on the indoor side. On the other hand, a gap is provided between the top portions of the first and second concave grooves located on the outdoor side. Therefore, if it implements such a gist, the shape of a ditch and a connecting material is not restricted to what relates to an embodiment mentioned above. Hereinafter, some modified examples of the shapes of the concave groove and the connecting material will be described.

  In the first modification shown in FIG. 11A, the groove 15A formed in the upper end of the lower wall panel 10B is different from the wall panel 10 shown in the present embodiment, and the upper wall panel 10A. Similarly, the distance from the indoor-side top 15a to the bottom 15b is longer than the distance from the outdoor-side top 15c to the bottom 15b, that is, the indoor-side top 15a is formed relatively higher.

  As a result, as shown in FIG. 11B, even if the indoor side top portions 15a, 15a of the wall panels 10A, 10B abut against the indoor side protrusions 18a of the connecting member 18, the outdoor top portion of the upper wall panel 10A. 15c and the outdoor protrusion 18c of the connecting member 18 do not contact each other, and a gap G is formed between them. In addition, the outdoor top portion 15c of the lower wall panel 10B and the outdoor protrusion 18c of the connecting member 18 do not contact each other, and a gap G is formed between them.

  Therefore, even if foreign matter is caught between the outdoor top portion 15c of the upper wall panel 10A and the outdoor protrusion 18c of the connecting member 18 at the outdoor side during assembly, the foreign matter causes the indoor top portion 15a of the wall panel 10A. And the contact of the indoor ridge 18a of the connecting member 18 is not hindered. Further, even if a foreign object is caught between the outdoor top part 15c of the lower wall panel 10B and the outdoor protrusion 18c of the connecting member 18, the foreign substance causes the indoor top part 15a of the wall panel 10B and the connecting member 18 to The contact of the indoor ridge 18a is not hindered.

  In the second modified example shown in FIG. 12A, the concave groove 15 at the lower end of the upper wall panel 10C has the same height between the indoor side top portion 15a and the outdoor side top portion 15c as in the lower wall panel 10. Formed identically. However, the outdoor protrusion 18c1 of the connecting member 18A is smaller in the height direction than the indoor protrusion 18a, that is, is formed thinner.

  As a result, as shown in FIG. 12 (b), even if the indoor side top portions 15a and 15a of the wall panels 10 and 10C abut against the indoor side protrusions 18a of the connecting member 18A, the outdoor side of the upper wall panel 10C. The top part 15c and the outdoor side top part 15c of the lower wall panel 10 do not come into contact with the outdoor side protrusion 18c of the connecting member 18A, and gaps G and G are formed between them.

  Therefore, even when foreign matter is caught between the outdoor top portion 15c of the wall panel 10 or 10C and the outdoor protrusion 18c of the connecting member 18A at the outdoor side during assembly, the foreign matter causes the indoor side of the wall panel 10 or 10C. Contact between the top portion 15a and the indoor-side protrusion 18a of the connecting member 18A is not hindered.

  In this case, the center of the outdoor ridge 18c is not necessarily the same as the center of the indoor ridge 18a in the height direction, for example, the lower end is the lower end of the indoor ridge 18a, or The upper end may be formed to be the same as the upper end of the indoor ridge 18a. As a result, one large gap is formed. Note that, here, the protrusion 14 at the upper end of the upper wall panel 10C has a shorter distance from the indoor bottom 14a to the central top 14b than the distance from the outdoor bottom 14c to the bottom 14b, that is, a higher position. Is provided.

  A further modification of this concept is the third modification shown in FIG. In this modification, the wall panels 10 and 10C are the same as those according to the second modification, but the connecting member 18B does not have the outdoor protrusion 18c.

  As a result, as shown in FIG. 13B, even when the indoor side top portions 15a and 15a of the wall panels 10 and 10C come into contact with the indoor ridges 18a of the connecting member 18B after assembly, as shown in FIG. The outdoor top portion 15c of the ten concave grooves 15 and the outdoor top portion 15c of the concave groove 15 of the upper wall panel 10C are not in contact with each other, and a gap G is formed therebetween.

  Therefore, even if foreign matter is caught between the outdoor top portion 15c of the wall panel 10 and the outdoor top portion 15c of the wall panel 10C at the outdoor side during assembly, the foreign matter is caused by the foreign matter between the indoor side top portions 15a of the wall panels 10 and 10C. The contact is not hindered.

  The 4th modification shown in Drawing 14 (a) is constituted so that connecting material 18C may be shown positively as a cosmetic mall. In this case, at the lower end of the upper wall panel 10D, the distance from the indoor side top portion 15a to the bottom portion 15b is longer than the distance from the outdoor side top portion 15c to the bottom portion 15b. A relatively high concave groove 15A is formed.

  As shown in FIG. 14 (a), the indoor-side protrusion 18a of the connecting member 18C is formed into a shape that fits between the groove 15 and A5A, while the visible portion is: While expanding to the indoor side, it expands along the surfaces of the wall panels 10 and 10D.

  As a result, as shown in FIG. 14B, as in the case of the present embodiment, even if the indoor side top portions 15a, 15a of the wall panels 10, 10D abut against the indoor side ridge 18a of the connecting member 18C, The outdoor top 15c of the upper wall panel 10D and the outdoor protrusion 18c of the connecting member 18C do not contact each other, and a gap G is formed between them. Therefore, even if foreign matter is caught between the outdoor top portion 15c of the upper wall panel 10A and the outdoor protrusion 18c of the connecting member 18 at the outdoor side during assembly, the foreign matter causes the indoor top portion 15a of the wall panel 10A. And the contact of the indoor ridge 18a of the connecting member 18 is not hindered.

  In addition, the joint between the wall panels 10 and 10D is completely invisible. For example, even if the width of the joint is different between the right and left of the wall panel, the expanded portion of the connecting member 18C Because it is covered, 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. In this case, if the wall panel 10B according to the first modification is employed as the lower wall panel, a gap G can be provided between the wall panel 10B and the outdoor protrusion 18c of the connecting member 18C. .

  The fourth modification shown in FIG. 15 is the same as the structure described in the present embodiment, but in this modification, the same wall panels 10E and 10E are used as the upper and lower wall panels. It is different from the present embodiment in that it is adopted.

  That is, at the lower end of the wall panel 10E, the distance from the indoor-side top 15a to the bottom 15b is longer than the distance from the outdoor-side top 15c to the bottom 15b, that is, the indoor-side top 15a is relatively A high concave groove 15A is formed.
