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.

  In the unit bathroom which is one form of this unit room, an extruded cement board whose upper and lower end surfaces are formed in a shape of tongue and groove (one joining method by carving one convex and the other concave) is placed horizontally on the waterproof pan. Stack and fix the longitudinal ends of the extruded cement plates stacked above and below to corner columns and door vertical frames, etc., and connect and fix the upper end to the ceiling panel, and the lower end to the waterproof pan. A horizontally stacked structure has been proposed in which a side wall surface is constructed by fitting and fixing to a formed protrusion (see, for example, Patent Document 1).

  This structure can be spanned by a single panel in the lateral direction from the wall end to the other end, and because the upper and lower panels are fitted to the tongue-and-groove joint, Since there is little risk of the center of the direction projecting indoors or retreating to the outdoor side, a connecting material and intermediate struts are unnecessary, and it can be said that the structure is rational.

  However, in this structure, for example, as shown in FIG. 14 (a), the concave portion 115 at the lower end of the upper wall panel 110A is externally connected to the convex portion 14 at the upper end of the lower wall panel 110 during assembly work. In order to achieve this, it is necessary to precisely align the front and rear. At the same time, as shown in FIG. 5B, the concave portion 115 cannot be fitted onto the ridge 114 well unless the upper wall panel 110A is held vertically. In particular, when there is only one worker, it is difficult to perform this work by lifting a heavy extruded cement board.

In order to avoid this problem, as shown in FIG. 5C, if the gap between the concave portion 115 and the convex portion 114 is increased, play between the wall panels 110 and 110A is increased and rattling occurs. There is a risk of doing. Further, a step is generated at the upper and lower wall panel joints, and the design properties are lowered. Furthermore, when watertightness is required, the fixing of the watertight packing interposed in the connecting portion becomes loose and the watertightness is lowered.

  INDUSTRIAL APPLICABILITY The present invention has an effect of obtaining a unit room wall panel having a design property and watertight reliability 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 10A are joined to the tongues and placed on the wall panel placing part 2a provided on the outer edge of the floor 2 and are passed between the corner posts 4 and 4 which are erected. . 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.

  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. The ridges 14 are formed in a shape that gradually narrows as the width goes from the bottom 14a to the top 14b. 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. And as shown in FIG.2 (e), the both ends of a surface material are simply bend | folded at right angles to the back side, and the edge part of the core material 12 is protected.

  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. The groove 15 </ b> A provided in is formed in a shape that fits with the ridge 14 of the wall panel 10. That is, the groove width of the concave groove 15A gradually expands from the bottom 15b toward the top 15a. Further, the upper end of the wall panel 10A is simply bent at a right angle to the back side, like both side ends.

  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 portion 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, 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).

  At this time, even if the wall panel 10A is not directly above the front-rear direction of the wall panel 10, as shown in FIG. 8A, when the inclined side surface of the groove 15A abuts the inclined side surface of the ridge 14, The panel 10A slides down along the slope and is automatically placed at a predetermined position.

  Moreover, even if the wall panel 10A is held in a state of being inclined in the front-rear direction, as shown in FIG. 8B, the inclined side surface of the groove 15A is convex as in the case of FIG. When abutting against the inclined side surface of the wall 14, the wall panel 10A slides down along the slope and is automatically placed at a predetermined position. This is particularly effective when it is difficult to hold the wall panel 10A vertically due to the presence of the pins 30d protruding from the corner backup material 30, as in this embodiment.

  The concave groove 15 at the lower end of the lower wall panel 10 may be formed in the same shape as the concave groove 15A at the lower end of the upper wall panel 10A. By forming in this way, the ridges 14 are always formed on one side end and the groove 15A is formed on the other side end, so there is no need to divide the types of wall panels into those for the upper stage and for the lower stage. 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. 9, 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. 10, the wall panels 10 and 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 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 portion 20b on the back side of the corner joint 20 is pressed and deformed between the wall panels 10 and 10A and the joint body 20a, and is crimped 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.

  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. 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.

  As described above, the gist of the present invention is that, as described above, the first wall panel having a ridge whose top width is narrower than the width of the bottom at one side end, and the ridge at the side end opposed to the above ridge. The second wall panel having a concave groove formed in a fitting shape is to be joined to a tongue and groove in the convex line and the concave groove. Therefore, the shape of the ridge is not limited to that according to the above-described embodiment. Hereinafter, some modified examples of the shape of the ridge will be described.

  In the first modification shown in FIG. 11A, the ridge 14A formed on the upper end of the lower wall panel 10B is formed in a shape in which the groove width narrows in a semicircular shape toward the top portion 15a. The groove 15B formed at the lower end of the upper wall panel 10C is formed in a shape that fits with the ridge 15A. Even if the ridges and grooves are formed as many as k, as in the wall panel joint structure according to the present embodiment, adjustment work load such as front-rear alignment between the wall panels and ensuring verticality is reduced, and assembly is performed. Work can be done easily.

  In the second modification shown in FIG. 12 (a), the ridge 14B at the upper end of the lower wall panel 10D has a constant width in the vicinity of the bottom, but from the middle in the height direction to the top. The width is gradually narrowed as it goes.

  In this case, the groove 15C at the lower end of the upper wall panel 10E has a constant groove width as shown in FIG. Even if formed in this manner, the adjustment work load such as front-to-back alignment between the wall panels and ensuring the verticality is reduced, and the assembly work can be easily performed, similarly to the wall panel joint structure according to the present embodiment. Obtainable.

  In the third modification shown in FIG. 13A, unlike the example described so far, a thin and flexible watertight material 16 is sandwiched between the groove 15C and the protrusion 14B according to the second modification. Is done. 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 ridges and grooves may be a combination of the ridges 14 and grooves 15A according to the present embodiment and the ridges 14A and grooves 15B according to the first modification.

  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, and the first wall panel having a ridge whose top width is narrower than the bottom width at one side end, and the above ridges. If the second wall panel having a concave groove formed in a shape to be fitted to the convex line at the side end opposed to the convex line is joined to the tongue in the convex line and the concave groove, Or a trunk room.
