Description

  The present invention relates to a connection structure of wall panels constituting a unit room such as a bathroom, and in particular, a corner column that stands on a corner of a unit room and supports the wall panel, and a connection between the wall panels using the corner column. Concerning 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.

  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. 10, it is necessary to stand and support the column 102 from the floor surface at the connection portion of the plurality of wall panels 101 constituting one wall surface.

  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. This is not only the problem of the intermediate struts standing in the middle of the continuous wall surface, but also the corner struts standing at the corners of the unit room.

  As one means for solving this problem, as shown in FIG. 11, a connecting member 113 is attached to the back surfaces of two wall panels 111 and 112 that are orthogonal to each other with a screw 114 or the like, and the center of the connecting member 113 is centered on the front side. An intermediate closing member 116 having a substantially U-shaped cross section is attached to the portion by screws 118, and the ends of both leg portions 6 a and 6 a of the intermediate closing member 116 are brought into contact with the surfaces of the wall panels 111 and 112. A connection structure is known in which the leg piece 119a is fitted to the intermediate closing member 116, the end of the closing member 119 is elastically contacted with the wall panels 111 and 112, and the interval T between the wall panels 111 and 112 is covered in a watertight manner. (For example, refer to Patent Document 1).

  However, according to this connection structure, a space for screw-fixing the hat-type intermediate closing member 116 between the two orthogonal wall panels 111 and 112 is required, and the joint width T is increased and the design property is lowered. . In addition, the screws 114 for fixing the connecting member 113 to the wall panels 111 and 112 and the screws 118 for fixing the intermediate closing member 116 to the connecting member 113 require a considerable number, which requires many man-hours and takes time to fix. . Furthermore, the screws 114 for fixing the connecting member 113 to the wall panels 111 and 112 can be fixed only from the outdoor side, and when there is not enough space between the building wall surface and the unit room wall surface, for example, at the time of renovation Cannot be constructed.

  As another means for solving the above-described problem, as shown in FIG. 12, two wall panels 123 and 123 which are adjacent to each other and the side portions 113a and 113a of the bent portions of the wall panels 123 and 123 are fitted from the back surface. A column member 124 that has a concave cross section and is erected by a column fixing member provided at a corner of the waterproof pan, a watertight member 125 that is inserted into the column member 124 from the surface of the wall panels 123 and 123, and the column There has been proposed a connection structure including a fixed piece that is inserted into the member 124 and temporarily fixed to two orthogonal wall panels 123 and 123 (see, for example, Patent Document 1).

  This connection structure is a current mainstream configuration. According to this configuration, the problems associated with the first connection structure are solved, but the following problems remain.

  First, in order to obtain the strength of the corner portion, the strut member 124 itself is required to have a considerable strength, and a large depth dimension (thickness) is required to obtain the strength of the strut member 124, that is, the sectional moment of inertia. If the thickness is secured, the indoor space of the unit room becomes narrow.

  When a wall panel having an inexpensive structure widely used in a unit room and having a backing material 129 attached to a steel plate 128 is used, a backing material 125b is attached to a portion where the wall panel 123 is engaged with the column member 124. Since it cannot be worn, the wall panel strength is reduced. As a result, the end of the wall panel 123 may be deformed when the watertight member 125 is press-fitted.

  Further, since the watertight material 125 is merely press-fitted between the wall panels 123 and 123 as described above, when the impact load is applied to the wall panel 123, the watertight material 125 floats from the surface of the wall panel 123, and the watertightness is improved. There is also a risk of lowering.

Furthermore, in order to lock the wall panel 123 to the support member 124, it is necessary to bend the end portion of the wall panel 123, it takes time for processing, and it is not possible to adopt an extrusion manufacturing method that can be continuously produced. The manufacturing methods that can be adopted are also limited.

  INDUSTRIAL APPLICABILITY The present invention has an effect that a corner column of a unit room having a design property, water-tight reliability, and high fixing strength and a wall panel connection structure using the corner column can be obtained.

  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 (height) 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, the weight is light, and it is easy to handle in transportation and assembly. And it can be manufactured at low cost.

  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.

  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 has an indoor-side top portion 15a and an outdoor-side top portion 15c erected with a bottom portion 14b located at the center of the wall panel 10 in the thickness direction.

  On the other hand, both side ends of the wall panel 10 are simply cut after the surface material 11 and the back surface material 13 are adhered to the core material 12 as shown in FIG. Thus, since both ends do not require any processing after cutting, it is possible to continuously produce them by an extrusion method or the like, thereby reducing the production cost.

  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 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 engaging pieces 20d are protruded 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 the engagement piece 20d being engaged with a slit 30d, which will be described later, 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.

  A plurality of slits 30d into which the engaging pieces 20d of the corner joint 20 are engaged are formed in the corner joint engaging portion 30a 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). At this time, since the wall panel 10 is erected by the corner backup material 30, the weight is not completely applied to the lower end of the bent surface material 11, and there is no possibility that the surface material 11 is deformed.

  Then, the concave groove 15A at the lower end of the upper wall panel 10A is fitted into the ridges 14 at the upper end of the lower wall panel 10 and joined by tongue and groove, and then the locking hole 12a of the upper wall panel 10A is raised. The wall panel 10A is erected by being externally fitted to the pin 30d of the corner backup material 30 provided (step S3). As described above, positioning can be performed simply by fitting the locking hole 12a to the pin 30d, so that even a single worker can easily assemble the wall panel.

  Subsequently, as shown in FIG. 7, the engaging piece 20d of the corner joint 20 is engaged with 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.

  When the wall panels 10 and 10A are fixed in this manner, both side ends thereof are covered with the joint body 20a and the corner backup material 30 of the corner joint 20, so that the cut surface is not seen and special protection is also provided. do not need.

  Further, 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 and 10A are pressed, no step is generated between the upper wall panel 10A and the lower wall panel 10, so that the design is not deteriorated.

  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. Further, since the wall panel can be fixed simply by engaging the engaging piece 20d of the corner joint 20 with the pin 30d of the corner backup member 30, the wall panel can be easily assembled by one worker alone.

  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 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 even in a vertical wall panel, it is necessary to provide an intermediate column in the middle of the wall surface. It is possible to adopt.
