Description

  The present invention relates to a wall structure of a bathroom unit, and more particularly to a wall structure of a protruding portion that protrudes to the outside from a wall panel erected from an outer edge of a floor pan or a bathtub.

  In a unit bath that is widely used as a bathroom in general households, the size of the unit bath is almost determined by the size of the waterproof pan that forms the floor.

  However, since the waterproof pan is manufactured using FRP or the like, the types are limited. For this reason, a large gap may be formed between the wall panel of the unit bath and the building wall located on the back surface thereof.

  In particular, if there is an obstacle such as a beam hanging, a reverse beam standing or a column protruding, a small waterproof pan must be selected to avoid interference with it. This gap will be further increased.

  Conventionally, various studies have been made to provide a protruding portion outside the waterproof pan to reduce this useless space and to use the bathroom space as much as possible.

  However, some of them can be used only when the size of the gap is known in advance and the dimensions are determined at the time of bathroom design. That is, in the case of bathroom remodeling, the detailed gap dimensions are often not known unless the existing bathroom is dismantled, and there are many cases that cannot be sufficiently handled (for example, see Patent Document 1).

  In addition, when there is a gap between the bathroom and the building frame, there is a plan to open a bathroom wall facing this gap and install a niche panel here to secure a space for placing small items in the bathroom. Proposed. Here, if the niche panel is constituted by two members inside and outside and the two members are slid so that the depth amount can be adjusted, it is possible to cope not only at the time of new construction but also at the time of renovation (for example, , See Patent Document 2).

  However, even if the depth can be adjusted, if the width and height are not changed, the case where the depth is adjustable is limited. In addition, there remains anxiety about the water performance between the two members.

  Further, as a structure of this protruding portion, among the wall panels erected around the floor pan, at least one side wall panel of the floor pan is divided into an upper wall panel and a lower wall panel, and the bottom panel is erected on the floor pan. A support member mounted along the outer surface of the wall panel protrudes outwardly, and protrudes outwardly and substantially horizontally from the upper end of the lower wall panel on the upper surface of the support member formed in a substantially horizontal plane. In a unit room provided with a protruding portion formed by placing an upper wall panel on the outer end of the protruding member, the supporting member is a vertical piece along the outer surface of the lower wall panel, It has a horizontal piece that is connected to the upper end of the vertical piece and extends in the outward direction and substantially in the horizontal direction, and an upper surface mounting portion that protrudes inward from the connecting part of the vertical piece is provided at the inner end of the horizontal piece, Screw the lower surface of the upper surface mounting part along the upper edge of the lower wall panel That the longitudinal pieces screwed through the screw member to the outer surface of the lower wall panel has been proposed with screwed via a (e.g., see Patent Document 3.). According to this structure, it becomes possible to provide the protrusion part which supports a protrusion member stably by the support member firmly attached to the lower wall panel.

  However, even with this structure, although the depth and height can be adjusted on site, the position where this projecting member can be attached is limited to the frame lined on the four circumferences of the wall panel, so the size in the width direction is It can be adjusted only in the width unit of the wall panel, and the degree of freedom in avoiding the interference with the above-mentioned pillar is not high.

In addition, the support member is screwed to the frame of the lower wall panel from above and from the outside, but the screwing from the outside does not allow tools to enter depending on the distance between the wall panel and the building wall, Work may be difficult.

  By the way, when remodeling an old building, there are no drawings left, and it is often possible to know the existence of a dead space and its size only after the existing bathroom is broken. And we want to make the best use of the dead space.

  In such a case, if the arrangement of the member was made after measuring the size, the delivery period was awaited and the construction period was prolonged.

  The present invention has been made in consideration of the above-described circumstances, and the wall structure of a bathroom unit can be provided with a protruding portion of any size at an arbitrary position corresponding to a dead space generated at the bathroom unit installation site. Is intended to provide.

  Another object of the present invention is to provide a wall structure of a bathroom unit that can be mounted by adjusting the position and size of the protruding portion when the bathroom unit is installed, even if the size of the dead space is not known before the bathroom unit is installed. There is to do.

  In order to solve the above-described problems, the wall structure of the bathroom unit according to the present invention is provided with an opening in a part of the wall panel, and a protruding portion protruding from the opening to the outdoor side. The bathroom unit has a hook part that is hooked to the lower side of the opening at the upper end, and a base part that hangs from the lower side in contact with the back surface of the wall panel and the vicinity of the upper end of the base part. A plurality of lower support members having an arm portion extending to the outside of the bathroom, a connecting material for connecting the plurality of lower support materials at arbitrary positions, and a farthest end from the base portion of the arm portion of the lower support material A back panel that is substantially the same shape as the opening erected in the vicinity of the opening, a frame that is laid between the peripheral edge of the opening and the peripheral edge of the back panel, and closes the side of the protruding portion; And a connection frame that connects the back panel Those formed from the made taking out portion.

  Preferably, the arm part preferably has a water gradient descending from the base part toward the base part side from the base part, and the lower support member is as claimed in claim 2. As described in Item 3, the length of the arm portion and the base portion can be adjusted.

  According to the wall structure of the bathroom unit according to the present invention, a protrusion having an arbitrary size can be provided at an arbitrary position corresponding to a dead space generated in the bathroom unit installation site.

  Moreover, even if the size of the dead space is not known before installing the bathroom unit, the present invention provides an effect that the position and size of the protruding portion can be adjusted and installed when installing the bathroom unit.

  An embodiment of a wall structure of a bathroom unit according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an overall outline of an embodiment of a bathroom unit 1 having a wall structure according to the present invention.

  As shown in the figure, the bathroom unit 1 includes a waterproof pan 2 constituting a floor of a washing place and a bathtub 6 mounting portion, a wall panel 3 constituting a wall surface separated from a building wall, and on the wall panel 3. A closed bathroom space is formed by the ceiling panel 4 to be placed and a door (not shown) through which a user can enter and exit.

  The waterproof pan 2 is integrally formed using a resin material such as FRP, or when the size is large, the waterproof pan 2 is divided into two or more in consideration of the carry-in property at the time of installation. It is assembled in one piece to prevent water leakage at the site.

  The wall panel 3 is formed such that a plaster board or the like is lined on a steel sheet whose surface is decorated with a resin sheet so that the wall panel 3 can stand on its own. (Not shown).

  The ceiling panel 4 is formed by lining a plasterboard or the like on a steel plate whose surface is decorated with a resin sheet, and is attached on the wall panel 3 via a connecting frame (not shown). Note that the joint portion between the wall panel 3 and the ceiling panel 4 is covered with a decorative edge 5.

  Various water supply and drainage facilities are provided in the bathroom space thus formed. That is, the bathtub 6 is installed at one end of the waterproof pan 2, and the side surface on the washing area side is closed by the bath apron 7. A bathtub faucet 8 is attached to the upper part of one end of the short side of the bathtub, and a washing faucet 10 is installed on the washing area side via a washing area counter 9. A shower 11 branches from the washing faucet 10. In the vicinity of the boundary between the bathtub 6 and the washing place, there is a drain trap (not shown) that collects drainage from the washing place and the bathtub 6 and drains it to the outside.

  This bathroom unit 1 is equipped with equipment such as a shelf 13 for placing a mirror 12 and a shampoo bottle, a towel rack 14 and the like, and on the side of the longitudinal wall panel 3 of the bathtub 6 is erected on the outer edge of the waterproof pan 2. A take-out portion 20 according to the present invention is formed as a protruding portion protruding from the wall panel 3 to the outside of the bathroom unit 1. The take-out unit 20 can provide a feeling of opening by expanding the bathroom in a limited space, and can be used as a storage place for small items used in the bathroom or as a bath lid storage place during bathing.

  As this protrusion, from the inside of the bathroom unit 1, the opening OP provided in the wall panel 3 and the wall panel 3 left around the opening OP are disposed in parallel to the opening OP at a position deeper than the opening OP. A back panel 21 having approximately the same shape as OP, a frame 22 that is installed between the periphery of the opening OP and the periphery of the back panel 21, and closes the side surface of the take-out portion 20, and the frame 22 and the back panel 21 The connection frame 23 that connects the frame 22 and the back panel 21 can be seen.

  The opening OP is located at a position where the lower end is slightly higher than the top of the bathtub 6 and the upper end is located slightly below the ceiling. The side end on the bathtub faucet 8 side is located at a position retracted from the corner of the wall panel 3, whereas the side edge on the opposite side extends to the vicinity of the corner.

FIG. 2A shows a longitudinal sectional view including the take-out portion 20 of the bathroom unit 1 shown in FIG. 1, and FIG. As shown in FIG. 2 (a), the length of the building wall area bath unit 1 is mounted to the building wall Despite the L _0, reverse beam RB has a length L ₂ rises from building floor to occupy can not L ₁ only be considered as the length of the installation area of the waterproof pan 2, only upright wall panels 3 a waterproof pan 2 outer edges, dead space length substantially L ₂ occurs. Therefore, if the take-out unit 20 is provided, this dead space can be eliminated.

On the other hand, as shown in FIG. 2 (b), the width of the building wall area bath unit 1 is mounted to the building wall Despite the W _0, the width W ₂ column C protrudes from the building wall occupation to order, can only use a maximum W ₁ as the width of the takeout section 20. That is, the take-out part 20 having the same width as the full width of the bathroom unit 1 cannot be formed. In this case, in the type in which the projecting member is attached to the frame lined on the four circumferences of the wall panel, only one wall panel and a half width of the bathroom unit can be formed, and a dead space still remains. According to the wall structure of the bathroom unit according to the present invention, it is possible to form the take-out portion 20 of an arbitrary size at an arbitrary position at the stage of unit assembly, and the dead space that can be generated is effective to the maximum limit. Can be used.

  As shown in FIGS. 2A and 2B and FIG. 3, the carry-out portion 20 according to the present invention includes a lower support member 24 and a connecting member 26 in addition to the back panel 21, the frame 22, and the connection frame 23. In this embodiment, a lower back panel holding member 25, an upper support member 27, and an upper back panel holding member 28 are further added.

  The back panel 21 is formed by cutting the same material as that of the wall panel 3 into a size required at the site. From the viewpoint of designability, a color different from that of the wall panel 3 may be used, and if it has a certain strength or more, it can be formed of a different material.

  The frame 22 is a combination of four resin plates and a frame body that opens on the bathroom unit 1 side and the back panel 21 side. The main body 22a that forms the side surface of the take-out portion 20 and the main body 22a are folded. A fitting portion 22b that is bent and locked to the peripheral edge portion of the opening OP, and a fitting recess 22c is provided on the rear surface of the main body 22a so as to project over the entire length thereof. Screwed with a resin plate and screws 30 adjacent at the side ends (see FIG. 4).

  The lower support member 24 has a bracket-like shape, and its role also serves as a bracket that receives a load applied to the take-out portion 20 including its own weight. Since the take-out portion 20 is used for a bath lid to be placed or for a bather to put his / her arm on it, the take-out portion 20 must be able to withstand a certain amount of load. It is necessary to give the sheath strength, which is uneconomical. By adopting the lower support member 24, it is possible to support the load applied to the take-out portion 20 without increasing the thickness of the frame 22. Accordingly, at least two lower supports 24 are attached.

  The lower support member 24 is made of a galvanized steel plate or the like, and extends substantially horizontally from the vicinity of the base portion 24a that contacts the back surface of the wall panel 4 located below the opening OP to the outside of the bathroom unit 1 from the vicinity of the upper end of the base portion. It consists of an arm part 24b that receives the load of the output back panel 21, and a reinforcing part 24c that is arranged orthogonal to both the base part 24a and the arm part 24b to prevent the arm part 24b from bending. A hook portion 24d is provided for hooking the lower support member 24 to the edge of the wall panel 4 located below the opening OP.

  In the arm portion 24b, a number of screw holes 24e are formed in two rows at a pitch of 10 mm, for example, to facilitate positioning of the lower back panel holding member 25 described later. If the lower support member 4 is made of a steel plate having a thickness of about 1.2 mm, it can be cut relatively easily. At the installation site of the bathroom unit 1, the arm portion 24b has a required length in accordance with the dead space. Can be cut into pieces. In addition, when the back of a reverse beam or the like is high, the base portion 24a can be cut and attached.

  Further, the arm portion 24b is provided with a water gradient that descends from an end portion farther from the base portion 24a to an end portion closer to the arm portion 24b. The member on the lower side of the frame 22 is provided with a water gradient from the back panel 21 to the wall panel 3 so that water cannot be collected. However, if a water gradient is also provided on the arm portion 24b serving as the base material, It becomes easy to provide a water gradient on the lower member of 22.

  In the hook portion 24d, two side holes 24g are formed on the side surface located on the base portion 24a, and the other side surface is extended from the top portion mounted on the wall panel 3 to the surface side of the wall panel 3. Are provided with two screw lower holes 24f. The lower support member 24 is fixed to the wall panel 3 below the opening OP by screwing screws 33 into these screw holes 24f and 24g from the inside of the bathroom unit 1.

  Thus, since the lower support member 24 is attached by hooking the hook portion 24d to the small edge of the wall panel 3 located below the opening OP, the effect is that it can be attached to any position of the opening OP and work easily. There is. Further, since the screwing work can be performed from within the bathroom unit, the workability is significantly improved as compared with the case where the work is performed behind the narrow wall panel 3. Further, by passing the screw 33 through both the front surface side screw hole and the back surface side screw hole, the wall panel 3 is sandwiched and there is no play between the hook portion 24d and the fixing strength is increased.

  A cushioning material is affixed to the surface of the base portion 24a that contacts the wall panel 3 so as not to damage the backing material on the back surface of the wall panel 3.

  The lower back panel holding member 25 is formed by bending one galvanized steel plate or the like, and fixing the base portion 25a on the arm portion 24b of the lower support member 24, and the base portion 25a being bent 90 degrees and rising upward. The back surface holding portion 25b that comes into contact with the back surface of the back panel 21 and the front holding portion 25c that is bent up at the center portion of the tip of the base portion 25a and rises upward to come into contact with the front surface of the back panel 21. .

  The base portion 25a is provided with a flaw hole 25d, and the flaw hole 25d and a predetermined screw lower hole 24e of the arm portion 24b are threaded into each other by a screw 31 so that the lower back panel holding member 25 is a lower support member 24. The arm portion 24b is fixed at an arbitrary position. And the lower end of the back panel 21 is inserted between the back surface holding part 25b and the front surface holding material 25c. Thus, the lower back panel holding member 25 also serves to position the back panel 21.

  The connecting material 26 is made of a galvanized steel plate or the like, and a cross section in the short direction is bent into a hat shape. Here, if the thickness of the connecting member 24 is about 1.2 mm, it can be easily cut at the installation site, so that its length can be adjusted to less than the carry-out portion 20 in accordance with the dead space. .

  Screw holes 26b are formed in the bottom portions 26a on both sides of the connecting member 26 at the same intervals as the two rows of screw holes 24e formed in the arm portion 24b. Then, the screw hole 26b and a predetermined screw lower hole 24e of the arm portion 24b are threadedly connected with the screw 32, and the connecting member 26 is screwed onto the arm portion 24b of at least two lower support members 24, These at least two lower support members 24 are rigidly connected to prevent the lower support member 24 from twisting left and right. Since the screw lower hole 24e drilled in the arm portion 24b is used, it is easy to attach at least two support members 24 in parallel.

  Further, at least two lower support members 24 are connected by a connecting member 26 as shown in FIG. The opening OP provided in the wall panel 3 is cut based on the size of the dead space measured in the field at the installation site of the bathroom unit 1, so that the cut end does not always maintain a straight line, and has some error. There is a possibility of bending. In such a case, if the lower support member 24 is screwed with the screw 33 at each position, the level of the lower support member 24 is different, and the frame 22 may be inclined or rattled. However, if at least two lower support members 24 are connected by the connecting member 26 prior to screwing the lower support member 24, the level can be adjusted and the above-described problems can be avoided.

  When connecting the support member 24, the connecting member 26 can obtain the same effect not only when connecting between the arm portions 24b but also between the base portions 24a and the reinforcing portions 24c. However, if the arms 24b are connected horizontally, it is advantageous for reinforcing the vertical load applied to the support member 24.

  Moreover, as long as the connection material 26 can exhibit the above-described function, the connecting material 26 may not have a hat-shaped cross section, but may have, for example, an angle-shaped cross section. However, if the hat type is adopted, even if the frame 22 is not high in strength, for example, the thickness is not large, the lower member of the frame 22 is placed on the top of the hat type to bend. There is an advantage that it can be prevented.

  The upper support member 27 includes a main body 27a such as an elongated galvanized steel plate, and a hook portion 27b that is bent at the tip thereof and is hooked to the lower end of the wall panel 3 positioned on the opening OP. Further, like the arm portion 24b of the lower support member 24, the main body 27a has a plurality of screw holes 27c formed in two rows at a pitch of 10 mm, for example, in order to facilitate the positioning of the upper back panel holding member 28.

  Since the hook portion 27b is held at the minimum height required to be hooked and screwed to the end of the wall panel 3, the minimum wall panel 3 remains at the top of the wall panel 3. If so, the dead space can be effectively used to the limit. Similarly to the hook portion 24d of the lower support member 24, the hook portion 27b has two fool holes 27d on the side surface facing the bathroom unit 1 and two screw holes on the side surface on the back surface side. A hole 27e is formed.

  The upper back panel holding member 28 is composed of two angle members 28a and 28b formed by bending a galvanized steel plate or the like into an L shape, with one surface contacting and the other surface being separated from each other. It is formed. The two angle members 28a and 28b are formed in a surface abutting with each other through a hole 28c. The hole 28c and a predetermined screw hole 27c of the main body 27a are connected to each other by a screw 34 so that the upper back The panel holding member 28 is fixed at an arbitrary position below the main body 27 a of the upper support member 27.

  The upper end of the back panel 21 is inserted between the spaced surfaces of the two angle members 28a and 28b. Since the lower end is held by the lower back panel holding member 25 and the upper end is held by the upper back panel holding member 28, the back panel 21 is temporarily fixed, and can stand on its own without assistance. As described above, the upper support member 27 and the upper back panel holding member 28 are for temporarily fixing the back panel 21, and the back panel 21 is connected to the back frame 23 as will be described later. Is fixed to the frame 22 by screwing.

  The connection frame 23 is formed by sticking aluminum extrusion-molded bars each having a substantially transverse cross section to the upper and lower edges and both side edges of the back panel 21 so that they form a frame.

  As shown in FIG. 6, the connection frame 23 includes a back panel side portion 23 a that is screwed to the back panel 21 with screws 35 and a frame side portion 23 b that is screwed to the frame 22 with screws 36. It is formed so as to be orthogonal to each other through an engaging portion 23c with which 29 is engaged.

  At both ends of the back panel side portion 23a, protrusions are provided so as to obtain a space in which the packing 40 can be sandwiched between the back surface of the back panel side portion 23a and the surface of the back panel 21. Similarly, protrusions are provided at both ends of the frame side portion 23b so as to obtain a space in which the ring-shaped packing 41 can be sandwiched between the rear surface of the frame side portion 23a and the surface of the frame 22. Thus, watertightness is improved by interposing the packings 40 and 41.

  The carry-out unit 20 according to the present embodiment also includes a cap 29 that covers the connection frame 23 in a watertight manner, as shown in FIG. The cap 29 is formed by installing fin portions 29b made of a soft resin material on both side ends of a main body 29a in which a hard resin material is formed in a substantially U-shape.

  The cap 29 is attached by fitting the both ends of the main body 29a to the outer end of the frame side portion 23b of the connection frame 23 and the engaging portion 23c after the silicon sealing. At this time, the fin portion 29b follows and contacts the surfaces of the back panel 21 and the frame 22, so that watertightness is increased in addition to silicon sealing, and design is also improved.

  The wall structure of the bathroom unit according to the present embodiment is configured as described above. Hereinafter, the assembly procedure will be described with reference to the flowchart shown in FIG.

  In the case of remodeling, first, when the existing bathroom is dismantled, the dimensions of the bathroom unit 1 installation site are measured, and the width, depth, and height of the take-out portion 20 are taken into consideration, taking into account the size and clearance of the waterproof pan 2 The dimensional details such as are determined (step S1).

  And according to said dimension, opening OP is formed in the wall panel 3 of the position in which the taking-out part 20 is provided (step S2). The opening OP may be formed before the wall panel 3 is erected or after it is actually erected at a predetermined position.

  Next, the lower support member 24 is cut into a dimension obtained from the depth dimension, and is hung on the wall panel below the opening OP (step S3), and the lower back panel holding member 25 is attached to the lower support member 24, and the lower support member. It attaches to 24 edge part (step S4). The lower back panel holding member 25 can be attached prior to the attachment of the lower support member 24 to the wall panel 3.

  Thus, when at least two lower support members 24 are hooked, the connecting member 26 is installed between them (step S5). Here, the lower support member 24 can be screwed to the wall panel 3.

  Similarly, when the upper support member 27 and the upper back panel holding member 28 are attached (steps S6 and S7), the back panel 21 is cut into a predetermined dimension (step S8) and cut into a predetermined length. The connected frame is attached (step S9).

  When the back panel 21 is ready to be mounted in this way, from the inside of the bathroom unit 1, the lower end of the back panel 21 is held by the lower back panel holding member 25 and positioned, and then the upper end of the back panel 21 is set to the upper back panel holding member. 27 and temporarily fixed (step S10).

  Subsequently, after cutting the upper, lower, left and right members constituting the frame 22 into a predetermined length, these are assembled to form the frame 22 (step S11), and this is inserted into the opening OP from inside the bathroom unit 1, The connection frame 23 attached to the back panel 21 and the end of the frame 22 are screwed with screws 36 (step S12).

  Finally, the cap 29 is fitted into the connection frame 23, and silicon sealing is performed on the connection portion where the cap 29 is not present (for example, between the constituent members of the frame 22) (step S13), and the attachment of the take-out portion 20 is completed. To do.

  Next, a modification of the present embodiment will be described with reference to the drawings. As shown in FIG. 8, the wall structure of the bathroom unit according to the present modification includes the support leg 50 that transmits the load applied to the lower support member 24 to the building side under the lower support member 24. The other configurations are basically the same as those in the present embodiment, and the same reference numerals are given and descriptions thereof are omitted.

  The support leg 50 includes a support leg main body 51, a long bolt 52, and a lock nut 53. The support leg main body 51 has a plate 51a attached to one end of a square pipe 51b and a nut 51c attached to the other end by welding or the like. To be formed. The square pipe 51b may be a round pipe as long as the long bolt 52 can be inserted.

  The plate 51a is a small piece such as a galvanized steel plate and is in contact with the lower surface of the arm portion 24b of the lower support member 24, and is screwed down according to the pitch of the screw holes 24e formed in the arm portion 24b and the interval between the two rows. Are drilled and screwed to the lower support member 24 with screws 37. Since a plurality of screw holes are drilled in accordance with the pitch of the screw holes 24e and the interval between the two rows, it is not necessary to provide lower screws at the installation site, and positioning is easy.

  The long nut 52 is screwed into a nut 51c welded to the lower end of the support leg main body, and is moved up and down to adjust the height of the entire support leg 50 to a height measured in advance in the field. If the height is obtained, the lock nut 53 is screwed to the nut 51c side to fix the long nut 52 at the height. The attachment of the support leg 50 is performed after the connection member 26 is attached, that is, after step S5 in the flowchart shown in FIG.

  As shown in FIG. 8, such a support leg 50 has to cut the base portion 24a of the lower support member 24 because the lower surface position of the carry-out portion 20 is low or the top end of the reverse beam RB is high. In particular, when the length cannot be secured sufficiently, or when a large load is loaded on the support member 24 due to the depth of the carry-out portion 20 being large or placing a heavy object on the carry-out portion 20, particularly in terms of strength. It is valid.

  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 length adjustment of the arm portion 24b of the lower support member 24 has been described by taking as an example a case where the arm portion 24b is cut to a predetermined length. It may be formed as a stretchable material by, for example, comprising two members. The same applies to the base portion 24a. If formed in this way, the cutting operation of the support member 24 can be omitted at the bathroom unit installation site, and workability can be improved.
