Description

  The present invention relates to an extended structure of a bathroom, and more particularly to an extended structure of a bathroom that extends beyond a base that partitions the bathroom.

  The bathroom in a general detached house must be installed in a space partitioned by a foundation on a concrete cloth foundation laid between 1 x 3/4 as defined in the former metrology method. Was normal.

  In many cases, this bathroom was divided into two sections, one facing the outer wall, a bathtub installed in one half, and the other half used for washing. The bathtub adopted here is a so-called sum formula, which has a depth, but has a short length from the waist to the toes and takes a bath with its knees bent.

  Such bathrooms are also aging and need to be renovated. In this remodeling, the so-called Western or Japanese-Western style bath that can bathe with a long bath and a long knee length, while the depth is small due to lifestyle changes, can be bathed with the knee extended. There is a high demand for the change.

  In order to meet this demand, a length of 3/4 on the side orthogonal to the outer wall is not sufficient, and the bathroom needs to be extended beyond the base located below to extend to the outer wall side.

  As a solution to this problem, the tub interferes with the base by forming a bay window on the outer wall of the building and providing a bench portion for sitting on the short side of the tub, which is higher than the height of the base. While the bathtub is extended to the outer wall side, the extended washing area adjacent to the extension part of the bathtub is formed as a counter panel of the bay window higher than the floor of the washing area (for example, (See Patent Document 1). The counter panel is supported by a height-adjustable support member disposed on the base.

  Moreover, although the installation direction of a bathtub differs, there also exists the example which has arrange | positioned the bathtub above the base (for example, refer patent document 2). In this example, an adjusting bolt as a support member is disposed between the back side of the floor pan on which the bathtub is disposed and the base.

Japanese Patent No. 3606828 (FIGS. 1 and 3) JP 2000-26569 A (FIG. 1)

  However, like the bathroom described in Patent Document 1, if the extension part of the washing place is configured as a counter panel, it cannot be used as a part of the washing place, and the extension part that is widened is sufficiently effective. It cannot be said that it is used for. Moreover, if the support member is disposed on the base, this is an obstacle and cannot be made the same height as the washing place.

  If the support member which supports a bathtub is arrange | positioned on a base like the case of patent document 2, the installation height of a bathtub will become high. If the installation height of the bathtub is increased, it is necessary to take measures such as increasing the straddle height during bathing or providing a step between the bathroom and the dressing room. It is against the notion and must be adopted.

  The present invention has been made in consideration of the above-mentioned circumstances. When the washing place is extended beyond the foundation, the extended portion is kept as high as the original washing place as the washing place floor. An object of the present invention is to provide a bathroom expansion structure that can be used effectively.

  Another object of the present invention is to extend the bathtub over the base, keep the installation height of the bathtub as low as possible, increase the straddle height of the bathtub, or create a step between the bathroom and the dressing room. An object of the present invention is to provide a bathroom extension structure that does not need to be provided.

  In order to solve the above-described problem, the extended structure of the bathroom according to the present invention extends from the main bathroom part provided in the area partitioned by the base of the building over the base as described in claim 1. In the extended structure of the bathroom in which the extended bathroom portion is extended, the fixed portion fixed to the base, and the top end extending from the fixed portion to the extended bathroom portion side is disposed below the base top end. A support bracket having a mounting surface and a support member for transmitting the load of the extended bathroom portion to the mounting surface of the support bracket.

    Preferably, the support bracket can be fixedly attached to the upper surface of the base of the building as described in claim 2, or is attached to the side surface of the base of the building as described in claim 3. It can also be fixed, and as described in claim 4, it may be fixedly attached to a side surface of a pillar of a building erected on the foundation.

  Furthermore, as described in claim 5, the support bracket preferably includes a torsion preventing material that prevents the mounting surface from rotating about the long axis of the base.

  On the other hand, in order to solve the above-described problem, an extended structure of a bathroom according to claim 6 is configured such that one of the beams and girders is provided from a main bathroom portion provided in an area partitioned by the beams and girders of the building. In the extended structure of the bathroom in which the extended bathroom part is extended beyond, the fixed part fixed to either the beam or the girder, and the top end extending from the fixed part to the extended bathroom part side has the beam and A support bracket having a placement surface disposed below one of the top ends of the girders, and a support member that transmits the load of the extended bathroom portion to the placement surface of the support bracket.

  According to the extension structure of the bathroom according to the present invention, when the washing place is extended beyond the base, the extended washing place is effectively used as the washing place floor by keeping the extension portion as high as the original washing place. be able to.

  In addition, when the bathtub is extended beyond the base, the installation height of the bathtub is kept as low as possible to increase the straddle height of the bathtub, or a step is provided between the bathroom and the dressing room. The effect that there is no need to do is acquired.

  DESCRIPTION OF EMBODIMENTS Embodiments of a bathroom extension structure according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of a bathroom unit 1 having a bathroom extension structure according to the present invention.

  The bathroom unit 1 is originally provided on a main bathroom portion 1A provided in a region surrounded by a base S laid on four sides with a pillar core of 1820 mm (6 scales) × 1365 mm (4.5 scales) on the outer wall side. The renovation which adds the extended bathroom part 1B expanded to is given. Therefore, the extended bathroom part 1B extends beyond the base S on the outer wall side. And the bay window 4 is attached to the upper part of the wall panel which forms the waist part on the outer wall side of the bathroom unit 1 for lighting and ventilation.

  The bathtub 3 is installed over the main bathroom part 1A and the extended bathroom part 1B along one of the wall surfaces orthogonal to the outer wall of the bathroom unit 1. A half-body bath step 3 a that is a substantially flat portion is provided at a position that is approximately 170 mm to 180 mm higher than the lowest portion of the bathtub 3 at the outer wall side end of the bathtub 3. When a bather takes a half bath in the bathtub 3, he sits on the half bath step 3a and takes a bath. The half body bathing step 3a is also used as a footrest during the whole body bathing.

  Thus, since the length of the bathtub 3 was extended to the extended bathtub portion 1B, the bather stretches the knee without being forced to bend in a cramped posture as before renovation. You can relax and take a bath.

  A washing space 2 is formed on the remaining floor surface of the bathtub 3 of the bathroom unit 1. This washing place 2 also spans the main bathroom part 1A and the extended bathroom part 1B, but no step is provided between them. Thereby, since the floor area increased by the extended bathroom part 1B can be used as a washing place, it can be used as stretched elongation even when bathing together, for example.

  FIG. 2 is a cross-sectional view showing an expanded structure of the washing place 2 portion as seen in the direction of arrows AA shown in FIG. The building body includes a base S laid on the fabric foundation F and a pillar C erected on the base S.

  On the other hand, in the bathroom unit 1, the floor of the washing place 2 is formed by installing the waterproof pan 8 on the gantry 9 installed on the floor D of the building body. The waterproof pan 8 extends from the main bathroom part 1A over the base S to the extended bathroom part B without a step. A wall panel 5 is erected on the outer end of the waterproof pan 8, and an unillustrated bay window 4 is attached to the upper portion thereof.

  The load applied to the main bathroom portion 1 </ b> A portion of the waterproof pan 8 is transmitted to the building floor D through the gantry 9. On the other hand, the load of the extended bathroom portion 1B portion is received in a concentrated manner on the support leg bolts 6 that can be adjusted in height, and is transmitted to the outer wall side base S via the support brackets 7 arranged below the support bolts 6.

  The support bracket 7 has its fixing portion 7b placed on the base S and screwed to the top end of the base S. The mounting surface 7 a of the support bracket 7 on which the support leg bolt 6 is mounted is provided at a position lower than the top end of the base S. Therefore, as shown in the figure, since the gap between the back surface of the waterproof pan 8 and the top of the base S can be made as small as possible, the height of the washing place 2 can be kept low. As a result, the washing place 2 and the dressing are removed. It is possible to eliminate a step between the chamber.

  In this case, the waterproof pan 8 of the washing place 2 of the extended bathroom part 1B constitutes the extended bathroom part of the present invention.

  FIG. 3 is a cross-sectional view showing the expanded structure of the bathtub 3 portion as seen from the direction of arrows BB shown in FIG. The structure of the building body is the same as that of the washing section 2 part.

  Under the bathtub 3, it has a double waterproof pan structure (full pan structure) in which a waterproof pan 8 is laid. In this double waterproof pan structure, the bathtub 3 is placed on the waterproof pan 8 laid on the entire floor via the gantry 9, and the wall panel 5 is also provided on the outer edge of the waterproof pan 8.

  Therefore, the load applied to the main bathroom part 1A portion of the waterproof pan 8 is transmitted to the building floor D through the gantry 9 as in the washing place 2, and the height of the load of the extended bathroom part 1B part is adjusted as in the washing place 2. The concentrated support leg bolt 6 is received and transmitted to the outer wall-side base S via a support bracket 7 disposed under the support bolt 6.

  Since the waterproof pan 8 of the main bathroom part 1A is lowered below the top of the base S, the lowest part of the bathtub 3 can be set lower than the water level (SBFL) of the washing place 2. Thereby, the straddle height at the time of entering / exiting from the bathtub 3 can be restrained small, and entering / exiting to the bathtub 3 becomes easier.

  On the other hand, the waterproof pan 8 below the bathroom extension portion 1B bulges upward to avoid interference with the base S, and is substantially the same height as the waterproof pan 8 of the washing area 2. However, since the half-body bath step 3a that is one step higher than the lowest part of the bathtub 3 is located on the bathroom extension part 1B, interference between the waterproof pan 8 and the bathtub 3 is also avoided.

  The load of the bathtub 3 and the expanded bathroom part 1B of the washing place 2 is received by being concentrated on the support leg bolt 6 and is transmitted to the outer wall side base S via the support bracket 7 arranged below the support bolt leg 6.

  Also in the bathroom extension structure on the bathtub 3 side, as in the bathroom extension structure in the washing area 2, the support bracket 7 has its fixing portion 7b placed on the base S and screwed to the top end of the base S. The mounting surface 7 a of the support bracket 7 on which the support leg bolt 6 is mounted is provided at a position lower than the top end of the base S. Therefore, as shown in the figure, the gap between the back surface of the waterproof pan 8 and the top end of the base S can be made as small as possible.

  In this case, the waterproof pan 8 under the bathtub 3 of the extended bathroom part 1B constitutes the extended bathroom part of the present invention.

  Moreover, as shown in FIG. 4, it can also be set as the half structure which does not provide the waterproof pan 8 under the bathtub 3. FIG. This half structure is also referred to as a bathtub with a washing area or a bathtub with an integrated washing area, and the floor of the washing area 2 and the bathtub 3 are integrally formed on a gantry 9.

  If the half structure is employed in this way, the waterproof pan 8 is not interposed between the base S and the bathtub 3, so that the height of the bathtub 3 can be further reduced. Therefore, the straddle height at the time of entering / exiting from the bathtub 3 can be further reduced, and entry / exit to the bathtub 3 is further facilitated.

  In this case, the support leg bolt 6 is screwed into the support leg rocket 10 attached to the bathtub 3 and the height is adjusted by moving the nut 10 up and down. Here, as in the bathroom extension structure in the washing place 2, the support bracket 7 has its fixing portion 7b placed on the base S and screwed to the top of the base S. The mounting surface 7 a of the support bracket 7 on which the support leg bolt 6 is mounted is provided at a position lower than the top end of the base S. Therefore, as shown in the figure, the gap between the back surface of the waterproof pan 8 and the top end of the base S can be made as small as possible.

  In this case, the bathtub 3 itself of the extended bathroom part 1B constitutes the extended bathroom part of the present invention.

  FIG. 5 shows details of the support bracket 7. The support bracket 7 includes a placement surface 7 a on which the support leg bolt 6 is placed and a fixing portion 7 b placed on the base S. A screw hole 7d is formed in the fixed portion 7b, and is fixed to the base S top end with a screw.

  The mounting surface 7a of the support bracket 7 is provided at a position lower than the top end of the base S as described above. Then, when the support leg bolt 6 is placed on the placement surface 7a and a load such as the waterproof pan 8 is loaded, both sides of the placement surface 7a are not bent so that the placement surface 7a is not bent by the weight. Reinforced by ribs 7c.

  Next, some modifications of the support bracket 7 will be described with reference to the drawings. The support bracket 7A shown in FIG. 6 is different from the support bracket 7 in that the fixing portion 7b is further extended, bent on the back surface of the base S, and formed so as to sandwich the base S. And since it is screwed to the base S not on the top end of the base S but on the back side, the load applied to the support leg bolt 6 is loaded off the center axis of the base S via the support bracket 7A. It has a strength greater than that of the support bracket 7 with respect to the torsion around the long axis of the base S.

  In the support bracket 7 </ b> B shown in FIG. 7A, the tip of the mounting surface 7 a is bent downward and the bolt 11 is supported by the double nut 12. FIG. 7B shows a state in which the support bracket 7B is attached to the extended structure of the bathroom. In this state, the head of the bolt 11 is placed on the side of the fabric foundation F below the base S and resists torsion around the long axis of the base S caused by the load applied to the support leg bolt 6. Works the same as 7c. The countermeasure against torsion by this method uses a concrete cloth foundation F, and is particularly effective when the wooden base S is rotted and the strength is reduced.

  The support bracket 7 </ b> C shown in FIG. 8 opposes torsion around the long axis of the base S by raising a vertical side 7 e provided on the side surface of the adjacent column C and screwing it to the column C. It is.

  Since the support bracket 7D shown in FIG. 9 has a certain length in the long axis direction of the base S, a plurality of support leg bolts can be mounted on the mounting surface 7a.

  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, but these embodiments are also included in the scope of the present invention.

  For example, in the above-described embodiment, the case where the bathroom extension structure is used for the first floor portion of a general house has been described as an example. However, as illustrated in FIG. 9, the structure can be adopted on the second floor or more. It is. In this case, the bathroom unit 1 is different from the above-described embodiment in that the bathroom unit 1 is installed on a beam B, a girder G, or the like of the building, but other configurations are not different.
