  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a unit bus structure that eliminates the step of the entrance and exit without cutting off the rise of the waterproof pan where the door is attached.

In order to solve the above-described problem, the unit bath structure according to the present invention includes a door frame and a plurality of columns around the outer edge of a waterproof pan having a washing place and a bathtub mounting portion. In the unit bath structure in which the wall panel is installed between the columns, the outer peripheral upper surface of the waterproof pan is a wall panel mounting surface lower than the waterproof pan floor surface by the thickness of the door lower frame, and the wall panel mounting. A support fixture fixing surface located outside the surface and lower than the wall panel placement surface, and a rising portion located further outside and standing higher than the waterproof pan floor surface, and a column support fixture on the support fixture fixation surface It is attached and the support column is fixed to the support column .

Preferably, according to a second aspect of the present invention, the column support includes a portion that contacts the support fixing surface, a portion that contacts the rising portion, and an outside of the unit bus from the rising portion. a portion extending towards, which is constituted to so that a and a portion standing on the back of the strut.

  According to the unit bath structure according to the present invention, it is possible to provide a unit bath structure that eliminates the entrance / exit step difference without cutting off the rise of the waterproof pan at the position where the door is attached.

  In addition, the present invention extends the method in the unit bath by extending the support tool to the outside of the waterproof pan while eliminating the above-mentioned excision problem by installing and attaching a separate support tool at the rising edge. The effect that can be obtained.

  Furthermore, the present invention has an effect that the height of the waterproof pan can be easily adjusted because the gap between the waterproof pan and the building wall is enlarged by separating the previously cut portion.

  An embodiment of a unit bus structure according to the present invention will be described with reference to the drawings. FIG. 1 shows an overall outline of a unit bus 1 having a unit bus structure according to the present invention.

  As shown in FIG. 1, the unit bath 1 is installed adjacent to the dressing room D to form a bathroom, and includes a waterproof pan 2, a bathtub 3, a wall panel 4, a door 5, and a drain pit. Part 6.

  Further, as shown in FIG. 2, a ceiling panel 60 is attached on the wall panel 4 via a ceiling connection piece 61. The ceiling connecting piece 61 is formed by extruding a hard synthetic resin or the like into a hollow for lightening, and the surface located on the back of the ceiling is a rib so that it does not bend even if the weight of the ceiling panel 60 is supported. It is reinforced with.

  The ceiling connection part 61a of the ceiling connection piece 61 that connects the ceiling panel 60 is formed in a concave shape, and after the end of the ceiling panel 60 is inserted into the ceiling connection piece 61, the ceiling connection piece 61 is screwed with a screw 63 to prevent it from coming off. Similarly, the wall connecting portion 61b of the ceiling connecting piece 61 that connects the wall panel 4 is also formed in a concave shape. After the ceiling panel 60 is connected to the ceiling connecting piece 61, the wall connecting portion 61b is fitted over the wall panel 4 above. Is done. Then, screws are fixed using screws 64.

  A connecting edge between the ceiling panel 60 and the wall panel 4 is attached with a surrounding edge 62 so as to be blinded. This attachment is performed by fitting the fitting convex portion 62 a of the peripheral edge 62 into the fitting concave portion 61 c of the ceiling connection piece 61. And the fin part 63a made from a soft synthetic resin etc. adhere | attached on the wall side of the surrounding edge 62 formed by extruding hard synthetic resin etc. and the both ends of the ceiling side etc. is dented by the wall panel 4 and the ceiling panel 60. By bending, the gap between the peripheral edge 62 and the wall panel 4 and the ceiling panel 60 is sealed.

  As described above, by using the ceiling connection piece 61, the size of the ceiling panel 60 can be made 2 W smaller than the entire width of the unit bus 1. Therefore, for example, a maximum of 1300 mm × 1700 mm ceiling panel can be adopted as a single ceiling panel for the reason of manufacturing and transportation in a standard unit bath of about 1400 mm × 1800 mm. The cost can be greatly reduced as compared with the case of using two panels.

  The door 5 forms an entrance / exit part of the unit bath 1 and is installed on the side of the waterproof pan 2 facing the dressing room D. The door 5 includes two vertical frames 50 and 50 that form openings in the wall panel 4 and an upper frame (not shown), a lower frame 51 that connects the floor of the dressing room D and the waterproof pan 2, and the unit bath 1 side. And a single-opening door body 52 that can be opened and closed.

  The waterproof pan 2 is integrally formed of a resin material, and as shown in FIG. 1, a washing place 20 where a person can wash the body is formed on the door 5 side, and a bathtub 3 is installed on the other side. A placement portion 21 is formed, and these are partitioned by a bank portion 22 that rises upward.

  The washing section 20 is formed so that the outer peripheral upper edge is formed at the same height, and the floor surface where the drainage flows is inclined so as to descend in a mortar shape toward the drainage pit section 6 provided in the middle part in the longitudinal direction of the bathtub 3. It becomes the flowing water surface S1.

  The bathtub mounting portion 21 is formed one step lower than the washing place portion 20, and has a flowing water surface S <b> 2 that is inclined so that the floor surface of the drainage flows in a mortar shape toward the drain pit portion 6.

  And, on the side of the bathtub mounting portion 21 of the bank portion 22, a back bank portion 23 is erected in parallel with the bank portion 22, and water is supplied from the washing place 20 between the bank portion 22 and the back bank portion 23. A drainage groove 24 is formed for collecting and draining the overflowed overflow.

  The bathtub 3 is installed on the bathtub mounting part 21 of the waterproof pan 2 through a lower leg (not shown) as shown in FIG. The bathtub 3 includes a concave bathtub body 30 and an apron 10 that covers the side of the bathtub 3. Further, water supply / hot water supply facilities (not shown) and the like are attached to the bathtub 3 and the washing place 20.

  An apron 10 that covers the side of the bathtub 3 is attached to the washing body 20 side of the bathtub body 30 above the bank portion 22 of the waterproof pan 2. The apron 10 has a substantially rectangular shape, and the four circumferences are bent for reinforcement to form the rib 10a.

  The upper end of the apron 10 is detachably fixed below the rim surface 30a at the upper end of the bathtub body 30, the lower end hangs down from there to the bank portion 22, and the rib 10a at the lower end of the apron is as shown in FIG. The top surface of 22 is abutted and fixed to the rising 22a protruding to the bathtub mounting portion 21 side. In addition, a recess 22c is formed on the upper end surface of the bank portion 22 along the longitudinal direction in addition to the rising 22a.

  The apron lower joint material 11 is sandwiched between the bank portion 22 and the apron 10 over the entire length of the bank portion 22. The apron joint material 11 is made of a thermoplastic resin such as polypropylene, vinyl chloride, ABS, or elastomer, and is formed by an extrusion method. On the lower surface of the apron lower joint material 11, there are formed projections 11a that fit into the recesses 22c of the bank portion 22, and fin-shaped projections 11b are provided over the entire length of the apron 10 on the top and bottom sides and on the back side. It is formed.

  When the apron 10 is placed on the projection 11a of the apron lower joint material 11 so that the projection 11a fits into the recess 22c of the bank portion 22, the projection 11b on the back side of the apron 10 is pressed and deformed. However, due to the restoring force, the apron 10 is brought into close contact with the lower rib surface 10 a and sealed so that no gap is generated between the apron 10 and the bank portion 22. Further, the upper and lower projections 11c and 11c of the apron 10 are deformed to the outside when the apron lower joint material 11 is pushed between the lower rib surface 10a of the apron 10 and the bank portion 22, but the restoration thereof is performed. By the force, the apron 10 and the bank portion 22 are in close contact with each other, and the apron 10 and the bank portion 22 are sealed so as not to generate a gap. Furthermore, since the rising 22a is formed on the back surface side of the bank portion 22, even if the apron lower joint material 11 is cut and water on the washing place 20 side enters, it may flow into the bathtub mounting portion 21 side. Is prevented.

  As shown in FIG. 5, an apron horizontal joint material 12 is sandwiched between the side surface of the apron 10 and the wall panel 4. The apron horizontal joint material 12 is made of a thermoplastic resin such as polypropylene, vinyl chloride, ABS, or elastomer, like the apron lower joint material 11, and is formed by an extrusion molding method. The cross section of the apron horizontal joint material 12 has a main portion 12a that abuts against the wall panel 4, a leg portion 12b that is bent 180 degrees from the main portion 12a and has a length that is substantially half of the main portion 12a, and a leg portion 12b. Is formed on the opposite side in a substantially J-shape comprising fin-like protrusions 12c facing in the same direction as the leg portions 12b.

  Before attaching the apron 10 to the bathtub main body 30, the apron horizontal joint material 12 is mounted | worn so that the rib 10a of the side of the apron 10 may be pinched | interposed with the main part 12a and the leg part 12b. At this time, the projection 12c on the front side of the apron is pushed by the front surface of the apron 10 and deforms to the outside. However, due to the restoring force, the projection 12c comes into close contact with the surface of the apron 10 and creates a gap between the apron 10 Seal so that there is no.

  And if the apron 10 is attached to the bathtub main body 30, the main part 12a of the apron horizontal joint material 12 will be pressed, the clearance gap between the apron 10 and the wall panel 4 will disappear, and water leakage will be prevented.

  As shown in FIG. 6, a bathtub upper joint material 13 is sandwiched between the three rims 30 a excluding the apron 10 side of the bathtub body 30 and the wall panel 4 or a counter (if any). The bathtub top joint material 13 is also made of a thermoplastic resin such as polypropylene, vinyl chloride, ABS, or elastomer, like the apron side joint material 12 described above, and is molded by an extrusion molding method. The cross section of the bathtub upper joint material 13 is roughly divided into an upper surface portion 13a exposed on the side surface of the bathtub, and an insertion portion 13b extending downward from the upper surface portion and inserted between the rim 30a of the bathtub body 30 and the wall panel 4. It consists of. The upper surface portion 13a has a shape inclined downward toward the bathtub body 30 side. The insertion portion 13b further includes a fin portion 13c that protrudes from the side surface, and an engagement portion 13d that bends from the lower end toward the bathtub body 30 and engages with the rim 30a tip of the bathtub body 30.

  When the bathtub upper joint material 13 is inserted through the gap between the upper portion of the bathtub body 30 and the wall panel 4, the engaging portion 13 d engages with the lower end of the rim 30 a of the bathtub body 30 and is fixed to the bathtub body 30. Therefore, once engaged, the joint material 13 on the bathtub does not easily fall off.

  The upper surface portion 13 a stops water by contacting the bathtub body 30 and the wall panel 4. When inserting the bathtub upper joint material 13 into the gap by making the distance from the lower end of the upper surface portion 13a to the engaging portion 13d slightly smaller than the height of the bathtub rim 30a, the engaging portion starts from the lower end of the upper surface portion 13a. The upper surface portion 13a and the insertion portion 13b are deformed so that the distance to 13d matches the height of the bathtub rim 30a, thereby engaging the lower end of the bathtub rim 30a, and the upper surface portion 13a and the insertion portion 13b are deformed. The upper surface portion 13a is pressed against the bathtub body 30 by the restoring force, and good water-stopping property can be obtained. Also, the fin portion 13c abuts against the bathtub rim 30a, so that the water stoppage can be obtained also here.

  A unit bath structure in which the waterproof pan 2 of the unit bath 1 configured as described above is installed on the building floor F and the wall panel 4 is erected on the waterproof pan will be described with reference to FIG. As shown in FIG. 3, the waterproof pan 2 has a flange 70 that hangs down from the floor surface level over the four outer edges.

  As shown in FIG. 7, the top surface of the flange 70 is divided into three stages. Adjacent to the floor surface of the waterproof pan 2, a wall panel mounting surface 71 that forms a recessed groove that is one step lower than the floor surface, and adjacent to the wall panel mounting surface 71 and further down one step from the wall panel mounting surface 71. A support fixture fixing surface 72 that forms a concave groove, and a rising portion 73 that is adjacent to the support fixture fixing portion 72 and forms the outermost edge of the waterproof pan 2 and rises higher than the floor surface.

  In a predetermined position of the support fixture fixing surface 72, a level adjustment hole 74 having a hexagonal cross-section is formed through to pierce the waterproof pan 2 on the building floor F and attach a support bolt 75 for adjusting the height. The As shown in FIG. 7B, a level adjustment nut 76 is fixed to the lower end of the level adjustment hole 74, and the support bolt 75 is screwed into the level adjustment nut 76. A single-character groove 75b is provided at the top of the support bolt (the end opposite to the bolt head 75a) so that a flathead screwdriver can be inserted. This may be a cross-shaped groove so that a Phillips screwdriver can be inserted. Further, a rattling prevention nut 77 is screwed onto the support bolt 75 at the lower portion of the level adjustment nut 76. The level adjustment hole 74 may have a cylindrical upper portion as long as the cross section of the portion to which the level adjustment nut 76 is fixed is a hexagon.

  The level adjustment of the waterproof pan by the support bolt 75 is performed as follows. First, the support bolt 75 to which the backlash prevention nut 77 is externally screwed is internally screwed to the level adjustment nut 76 fixed to the level adjustment hole 74 in advance. At this time, the rattling prevention nut 77 is externally screwed in the vicinity of the bolt head 75a of the support bolt 75, and the length from the lower end of the bolt head 75a to the level adjustment nut 76 is set to a predetermined height of the waterproof pan 2. Install it slightly shorter than required.

When the waterproof pan 2 is placed at a predetermined position , a flathead screwdriver is inserted through the level adjustment hole 74, fitted into the groove 75b of the support bolt 75, and a rotational force is applied to the support bolt 75, whereby the waterproof pan 2 is predetermined. Screw down until it reaches the height of.

  When the height is determined in this way, a jig is inserted through the gap between the outer edge of the waterproof pan 2 and the building wall W, the rattling prevention nut 77 is screwed upward, and the level adjustment nut 76 is firmly contacted. Prevents rattling and loosening of screws. Thereby, the level adjustment of the waterproof pan 2 can be easily performed without making a hole in the floor surface of the waterproof pan 2.

  In addition, the diameter of the upper part of the level adjustment hole 75 from the part where the level adjustment nut 76 is fixed is made larger, and the rattling prevention nut 77 is screwed onto the support bolt 75 on the upper side of the level adjustment nut 76. it can. In this case, rattling prevention can be performed by inserting a jig through the level adjustment hole 74 and screwing the rattling prevention nut 77 downward.

  As shown in FIG. 7C, a support support 81 is screwed to the support fixing surface 72 with a screw 82. The support column 81 is formed by bending a metal plate, and extends from the rising portion 73 in the direction of the building wall W, a portion 81a that contacts the supporting fixture fixing surface 72, a portion 81b that contacts the rising portion 73, and the like. It consists of a protruding part 81c and a part 81d standing on the back of the support 80. The column 80 for holding the wall panel 4 is screwed and installed by a screw 83 on a portion 81 d of the column support 81 that stands on the back surface of the column 80.

  Thus, since the support column 81 extends outward from the outer edge of the waterproof pan 2, the support column is supported even if the distance L1 from the back surface of the support column 80 to the building wall W is the same as that of the conventional unit bath. In the portion where the tool 81 does not exist, the distance L2 between the building wall W and the outer edge of the waterproof pan 2 is relatively large, and therefore there is an advantage that a jig for adjusting the level of the support bolt 75 can be easily inserted.

  The support column 80 is formed by bending a steel plate or the like into a channel-shaped cross section, and bending both end portions further inward to form bent portions. The inclined surfaces of the bent portions are inclined portions 80a and 80a. A relatively large opening is formed between 80a and 80a. The wall panel 4 is attached between the columns 80 and 80 adjacent to each other (only one column 80 is shown in this figure).

  The wall panel 4 includes a surface material 40 such as a decorative metal plate (such as a vinyl chloride resin-coated steel plate) and a backing material 41 such as a gypsum board that lines the surface material 40. Both left and right ends of the surface material 40 are bent into a substantially J shape in the back direction (outside of the room) to form elastic locking portions 40a rich in elasticity. Then, the upper and lower ends of the surface material 40 are bent in a substantially L shape in the back direction (outside of the room) to form mounting pieces 40b.

  A panel joiner 45 is attached between the inclined portions 80a and 80a. The panel joiner 45 is a medium-hard material having both deformability and rigidity, and is a long material having a substantially Ω-shaped cross section. The elastic locking portion 40 a is elastically engaged with the inclined portion 80 a of the support column 80 via the panel joiner 45. For this reason, the elastic latching | locking parts 40a and 40a can be attached or detached to the support | pillars 80 and 80 from the indoor side.

  The mounting piece 40b of the wall panel 4 is mounted on a packing 46 laid on the wall panel mounting surface 71, and has a side surface that hangs down from the floor surface of the waterproof pan 2 to the wall panel mounting surface 71, and a surface material. Since the floor joint material 47 is tightly inserted into the gap with 40, water in the bathroom is prevented from leaking outside through this gap. In this case, since the fin part 47a of the inserted floor joint material 47 is hooked on the corner | angular part of the mounting piece 40b of the wall panel 4, the floor joint material 47 does not float up.

  Further, since the support fixture fixing surface 72 is provided at a position lower than the length obtained by adding the thickness of the column support fixture 87 and the head height of the screw 82 from the wall panel mounting surface 71, the presence of the screw head of the screw 82 is present. However, there is no obstacle to placing the placing piece 40b on the packing 46.

  FIG. 8 is a diagram for explaining a position where the column support 81 is arranged. There are two types of support pillars, one is a corner support pillar 84 attached to the corner of the waterproof pan, and the other is a support pillar 81 attached to each side middle part of the waterproof pan 2. It is.

  Corner strut supports 84 are attached to the four corners of the waterproof pan 2 and carry end wall panels 4 and 4 of orthogonal walls. The corner post support 84 is processed into a shape in which post support 81 arranged in a substantially orthogonal direction is connected by a connecting portion 84a.

  On the other hand, the support fixture fixing surface 72 of the waterproof pan 2 is provided with an inverted triangular pyramid-shaped recess 72a as shown in FIG. The recess 72a is provided at a position determined in advance from the size of the waterproof pan 2 and the width of the wall panel 4 employed. The recess 72a serves as a guide for guiding the mounting positions of the column support 81 and the corner support 85. And the corner support | pillar support tool 84 is hold | maintained so that the screw hole 85 may come on the hollow 72a, and is screwed with the screw 82. FIG.

  A normal support column 81 is attached to each side intermediate portion of the waterproof pan 2. The column support 81 is also held by a screw 82 so that the screw hole 85 is placed on an inverted conical recess 72 a drilled at a predetermined position of the support fixing surface 72.

  When the wall panel 4 is shifted back and forth, the length of each side changes. In this case, the wall panel at the center in the side direction has a constant width, and the length of each side is also adjusted by adjusting the width of the wall panel in contact with the corner. Alternatively, if the length of each side is increased without changing the width of the wall panel 4 according to the minimum case as in the case of the connection between the lower end of the wall panel 4 and the flange 70, the width is changed to the width. A matching vertical joint material may be sandwiched.

  FIG. 10 is a cross-sectional view showing the engagement between the door lower frame 51 and the waterproof pan 2 according to the present embodiment. In this figure, the door lower frame 51 is placed on the wall panel placement surface 71 of the flange 70 via the packing 46.

  Unlike the conventional example shown in FIG. 13A, the rising portion 73 according to the present embodiment does not directly fix the support column 80, and therefore the height thereof is not large. Therefore, the rising portion 73 shown in FIG. As described above, it is not necessary to cut the rising portion 73 located under the lower frame 51, and the position of the door 4 can be easily changed.

  Further, since the space formed by the side surface of the rising portion 73, the support fixture fixing surface 72, and the side surface of the support fixture fixing surface 72 on the wall panel placement surface 71 is a groove shape, If the groove is partitioned, even if the water stoppage by the packing 46 and the floor joint material 47 is broken, the leaked water is stored in the groove, and leakage to the outside can be reduced.

  Furthermore, if the height of the side surface of the waterproof pan 2 that hangs down from the floor surface to the wall panel mounting surface 71 is the same as the height of the portion of the lower frame 51 that contacts the portion, As shown, the level of the upper surface of the lower frame 51 is equal to the level of the floor surface of the waterproof pan 2 in contact with the lower frame 51, so that there is no step and no stepping occurs. Further, the level difference h1 between the dressing room D and the bathroom is also smaller than h2 in the conventional example shown in FIG. 13, and it is easier to use for the handicapped and the elderly.

  Next, the case where the position of the wall panel 4 is shifted back and forth to adjust the size of the unit bus 1 will be described. In the unit bus structure of this example, as shown in FIG. 11, the portion 81 c extending from the rising portion 73 of the support column support 81 that supports the support column 80 in the direction of the building wall W is longer than that of the above example. Basically different from those in the above-described embodiment, the other configurations are substantially the same, and the same reference numerals are given and description thereof is omitted.

  Thus, by changing the length of the portion 81c of the support column 81 extending from the rising portion 73 in the direction of the building wall W, the position of the support column 80 moves back and forth with respect to the position of the flange 70 of the waterproof pan 2. Thus, the position of the wall panel 4 can be moved back and forth. Therefore, the size of the unit bath space can be changed even if the same waterproof pan 2 is used, just by properly using the column support 81 depending on the distance from the outer edge of the waterproof pan 2 to the building wall W. A bathroom space can be obtained, and the space behind the wall panel 4 can be made small and effectively used.

  At this time, the floor joint material 47A sandwiched in the gap between the side surface hanging from the floor surface of the waterproof pan 2 to the wall panel placement surface 71 and the surface material 40, as shown in FIG. A thing with a width | variety large compared with the case is employ | adopted. Alternatively, the same floor joint material 47 and the same type of insertion material as the floor material may be sandwiched as described above. This not only increases the distance between the opposing wall panels 4 and 4, but also increases the area that can be used as a floor.

  Further, since the wall panel 4 is shifted to the building wall W side, the placement piece 40 b at the lower end of the wall panel 4 may be placed on the support fixture fixing surface 72. In this case, the packing 46 </ b> A laid under the placing piece 40 b is also laid on the support fixture fixing surface 72. However, since there is no change in the height of the mounting piece 40b, the height of the wall panel 4 is increased by using a packing 46A that is taller than the above-described case laid on the wall panel mounting surface 71. adjust. Also in this case, since the fin portion 47a of the inserted floor joint material 47A is hooked on the corner portion of the mounting piece 40b of the wall panel 4, the floor joint material 47A does not rise. Thereby, the water leakage from the outer periphery of the waterproof pan 2 to the back of the wall panel 4 is prevented.

  Subsequently, a modification of the present embodiment will be described with reference to FIG. The support bolt 75A for adjusting the height of the waterproof pan 2 in the embodiment described above is attached to the lower portion of the flange 70 of the waterproof pan 2, whereas the support bolt 75A in the unit bus structure of the present modification is shown in FIG. Thus, it differs fundamentally by the point attached to the flange 70 outer side of the waterproof pan 2, and another structure is substantially the same as embodiment mentioned above, attaches | subjects the same code | symbol and abbreviate | omits description.

  In this modification, the support bolt 75A is provided with a single-character groove 75b into which a flat-blade screwdriver is inserted at the end opposite to the bolt head 75a, and the bolt head 75a is inverted downward (building floor F) to fix the support bolt. The level adjustment nut 76 fixed to the tool 78 is screwed internally. On the level adjustment nut 76, a rattling prevention nut 77 is externally screwed onto the support bolt 75A.

  The support bolt fixing tool 78 is a metal plate that is bent so as to be in close contact with the bottom surface of the flange 70 and the side surface on the building wall W side, and is screwed to the flange 70 with a screw 79. As a result, the load of the unit bath 1 including the waterproof pan 2 is transmitted from the flange 70 to the building floor F via the support bolt fixture 78, the level adjustment nut 76, and the support bolt 75A.

  The level adjustment of the waterproof pan by the support bolt 75A is performed as follows. First, the support bolt 75A is internally screwed into a level adjustment nut 76 fixed to a support bolt fixture 78 screwed to the flange 70 in advance.

  At this time, the length from the lower end of the bolt head 75a to the level adjustment nut 76 is attached to be slightly shorter than the length necessary for the predetermined height of the waterproof pan 2, and the rattling prevention nut 77 is provided with the support bolt 75A. The outer fitting screw 75 is screwed in the vicinity of the groove 75b.

  When the waterproof pan 2 is placed at a predetermined position, a flathead screwdriver is fitted into the groove 75b, and the waterproof pan 2 is screwed down to a predetermined height by applying a rotational force to the support bolt 75A. When the height is determined in this manner, the rattling prevention nut 77 is screwed downward and is brought into firm contact with the level adjustment nut 76 to prevent rattling or loosening of the screw.

  As shown in FIG. 12 (a), even if the support bolt 75A is positioned outside the outer edge of the waterproof pan 2, the column support 81 is positioned farther from the building wall W than the portion 81d standing on the back of the column 80. Therefore, the distance between the wall panel 4 and the building wall W is not increased by the presence of the support bolt 75A. Nevertheless, the level adjustment of the waterproof pan 2 can be performed directly without going through the level adjustment hole or the like, and since the situation can be visually observed from above, the level adjustment of the waterproof pan 2 can be easily performed without making a hole. It becomes possible. Therefore, the anti-rattle nut 77 can be attached even after the level adjustment is completed.

  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.
