Description

  The present invention relates to a bathroom unit including a bathtub, a floor member, a wall member, and a columnar column member that supports the wall member.

  A bathroom unit including such a bathtub, a wall member, and a floor member is widely used because it is superior in workability and productivity to a so-called conventional bathroom. The floor member of the bathroom unit is formed of fiber resin reinforced plastic (hereinafter also referred to as FRP (Fiber Reinforced Plastic)) because it easily satisfies various required qualities such as strength, waterproofness and moldability as a bathroom floor. Yes.

  The floor member formed by FRP is excellent in order to satisfy the required qualities such as strength, waterproofness and moldability described above, but there are also problems to be solved. In the following Patent Document 1, one proposal is made in order to solve the recycling problem of FRP floor members. This recycling issue is caused by the fact that FRP is formed by binding a reinforcing material such as carbon fiber with a thermosetting resin, and is simply recycled by remelting it into a new product. This is a problem caused by the inability to apply the process.

  In order to solve such a problem, in Patent Document 1 below, a frame-shaped gantry installed on a building floor, a plate-shaped gantry fixed on the frame-shaped gantry, and a waterproof pan supported on the plate-shaped gantry. The floor member provided with these is proposed. The waterproof pan is made of a thermoplastic resin, the frame-shaped frame is made of steel, and the plate-shaped frame is formed by sandwiching a core material between two metal plates.

JP 2008-25122 A

  The conventional technology described above solves the above-mentioned recycling problem by forming the waterproof pan arranged in the uppermost layer with a thermoplastic resin, and also has a degree of freedom of material selection that cannot be obtained by an integrated structure of a single FRP material. It is an excellent technology that can be obtained.

  However, a thermoplastic resin has a large linear expansion coefficient, and has a property of expanding and contracting due to fluctuations in applied heat. Therefore, although the floor member alone has the excellent properties as described above, a gap may be formed between the floor member and the wall member provided so as to rise from the floor member depending on the temperature condition. If it is going to arrange a wall member along the perimeter of a floor member so that this crevice may not arise, since both ends of the wall member are restrained by the column member erected to support the wall member, There is a possibility that the center of the wall member will be drawn inward, making it impossible to assemble the wall member.

  This invention is made | formed in view of such a subject, The objective provides the bathroom unit which can assemble | assemble a wall member as aimed, forming a floor surface using a thermoplastic resin. There is.

  In order to solve the above-described problems, a bathroom unit according to the present invention includes a bathtub, a substantially rectangular floor member disposed at a position adjacent to one side of the bathtub, and standing around the bathtub and the wash floor member. It is a bathroom unit provided with the plate-shaped wall member and the columnar support | pillar member which supports the said wall member. The floor member is formed by foam-molding a thermoplastic resin, and a wall mounting portion on which the wall member is mounted is integrally provided on a peripheral portion of the other side excluding the side along the bathtub. A washing floor floor pan, a floor having a linear expansion coefficient smaller than the linear expansion coefficient of the washing floor floor pan and having a rigidity higher than the rigidity of the washing floor floor pan, and disposed below the washing floor floor pan And a support member. The washing floor floor pan has an extension allowing portion that can extend in the surface direction inside the wall placing portion. The strut members are attached to the floor support member, and at least a pair of the strut members are provided at intervals so as to be erected upward from the outside of the washing floor floor pan, and between the pair of strut members. The wash floor floor pan is stretched toward the pair of strut members so that a distance between a part of the wall mounting portions facing each other and the pair of strut members is a predetermined distance, and a horizontal plane projection region of the wash floor floor pan There is a correction means to correct.

  According to the present invention, since the washing floor floor pan constituting the floor surface of the washing place is formed of the thermoplastic resin, the carbon dioxide emission during molding can be reduced and the recycling can be facilitated. be able to. Since the washing ground floor pan is formed by foam molding, the internal pressure at the time of molding can be reduced, so that the cost of the molding die can be reduced, and the weight of the washing ground floor pan itself can be reduced. Since the washing floor floor pan is integrally provided with a wall placing portion for placing the wall member, it exhibits excellent waterproof performance by keeping the wall member placed on the wall placing portion. be able to. By attaching the support member to the floor support member, the wall member can be stably supported for a long period of time as compared to the case where the support member is attached to the washing floor floor pan.

  Furthermore, in the present invention, for example, even when the washing floor floor pan contracts and the target horizontal plane projection area cannot be secured, the target horizontal plane projection area is reduced by stretching the washing floor floor pan toward the pair of support members. Can be secured. In addition, since the washing ground floor pan is stretched toward the pair of strut members so that the distance between a part of the wall mounting portion facing between the pair of strut members and the pair of strut members is a predetermined distance, The wall mounting part of the floor pan can be arranged at a normal position for mounting the wall member. The column member is installed so as to stand upward from the outside of the washing floor floor pan, and the washing floor floor pan is extended to the column member side, so that it is arranged in a state where the plane dimensions of the bathroom unit are maintained. Can do. As a result, the wall member can be erected vertically along the column member, and the wall member and the ceiling panel can be attached in close contact. In addition, since there is an extension allowance part that can extend in the surface direction inside the wall mounting part of the washroom floor pan, the washroom floor is less forceful than when the entire washplace floor pan is stretched and deformed. The bread can be stretched in the plane direction. In addition, since the extension allowing portion is positively extended, the washing floor floor pan can be prevented from being damaged when the washing floor floor pan is extended.

  Further, in the bathroom unit according to the present invention, a water return wall portion is provided outside the wall placement portion so as to stand on the upper side, and the correction means corresponds to at least the pair of support members. It is also preferable to be provided at a position.

  In this preferred embodiment, since the correcting means is provided at a position corresponding to the pair of support members, the washing floor floor pan can be reliably stretched to a target position at a position corresponding to the pair of support members. Therefore, in the place where a pair of support | pillar member is arrange | positioned, a wall member can be reliably arrange | positioned in a regular position. Furthermore, since the water return wall portion is provided outside the wall mounting portion so as to be erected on the upper side, the wall member pushes the water return wall portion outward between the pair of support members. The wall mounting portion can be moved to the regular position, and as a result, the wall member can be erected at the regular position. Therefore, it is possible to correct the horizontal projection area of the washing floor floor pan and to stand the wall member vertically along the column member without providing the correcting means around the washing floor floor pan.

  In the bathroom unit according to the present invention, it is also preferable that the straightening means has a first straightening portion that is provided so as to push the water return wall portion toward the pair of column members.

  In this preferred embodiment, since the first straightening part pushes the water return wall part toward the pair of support members, even if the washing floor floor pan contracts, it is surely stretched to the support member side to correct the horizontal projection area. can do.

  Moreover, in the bathroom unit according to the present invention, the correction means includes a second correction portion provided integrally with the support member, and a fixing portion that fixes the first correction portion and the second correction portion. And the first correction portion is fixed to the second correction portion by the fixing portion, so that the first correction portion pushes the inner wall surface of the water return wall portion toward the support member, and the water return It is also preferable that the outer wall surface of the wall portion is in contact with at least one of the support member and the second correction portion.

  In this preferred embodiment, the first straightening portion for pushing out the water return wall portion and the second straightening portion to be fixed are provided integrally with the support member, and the outer wall surface of the water return wall portion is at least one of the support member and the second straightening portion. Since it pushes out until it contacts, the water return wall part can be reliably pushed out toward the support member. Since the first straightening part and the second straightening part are fixed by the fixing part, the washing place floor pan is securely stretched to the support member side without providing a mounting hole in the washing place floor pan including the water return wall part. The horizontal projection area can be corrected.

  In the bathroom unit according to the present invention, the second straightening portion is configured as a second straightening member attached to the floor support member, and the support member is attached to the second straightening member to support the floor. It is also preferable that it is attached to the member.

  In this preferable aspect, the second correction portion is configured as a second correction member, and the support member and the second correction member are configured so as to be integrated, thereby supporting the second correction portion on the floor. It attaches to a member and it comprises so that a support | pillar member can be indirectly attached with respect to a floor support member. Therefore, since the 2nd correction member can be comprised as an attachment member with respect to the floor support member of a support | pillar member, the whole structure can be simplified.

  Further, in the bathroom unit according to the present invention, a position restricting portion for restricting a displacement in a horizontal direction with respect to the floor support member is provided in a central region of the back surface of the wash floor floor pan facing the floor support member. It is also preferable.

  In this preferred embodiment, since the position restricting portion is provided in the central region on the back surface of the washing floor floor pan, the positional displacement of the entire washing ground floor pan in the horizontal direction is restricted based on the position restricting portion in the central region. Accordingly, since the correction means stretches the washing floor floor pan to the support member side with reference to the position restricting portion in the central region, uneven distribution of the stretching amount on each side can be suppressed. In other words, since the stretch amount on each side of the washing floor floor pan can be substantially equalized, the correction work at the time of installing the bathroom unit becomes easy.

Correction units CMa, which stretch the wash floor pan FP toward the pair of strut members so that the distance between a part of the portion FPc and the pair of support members becomes a predetermined distance, and correct the horizontal projection area of the wash floor pan FP, CMb (correction means) is provided.

  According to this embodiment, since the washing floor pan FP constituting the washing floor FPp is formed of the thermoplastic resin, the carbon dioxide emission during molding can be reduced and the recycling is easy. It can be. Since the washing ground floor pan FP is formed by foam molding, the internal pressure at the time of molding can be reduced, so that the cost of the molding die can be reduced, and the weight of the washing ground floor pan itself can be reduced. Since the wall placing part FPq for placing the wall members WP1 to WP4 is integrally provided in the washing floor floor pan FP, the state in which the wall members WP1 to WP4 are placed on the wall placing part Fpq is maintained. In this way, excellent waterproof performance can be exhibited. By attaching the first strut members PC1, PC2 and the second strut members PP1, PP2, PP3 to the floor support member HP, the wall member is stable in the long term as compared with the case where it is attached to the wash floor pan FP. WP1-WP4 can be supported.

  Furthermore, in this embodiment, even when the washing floor floor pan FP contracts and the target horizontal plane projection area cannot be secured, the target horizontal plane projection area is obtained by stretching the washing floor floor pan FP toward the pair of support members. Can be secured. In addition, since the washing floor floor pan FP is stretched toward the pair of column members so that the distance between a part of the wall placing part FPq facing the pair of column members and the pair of column members becomes a predetermined distance. The wall placing part FPq of the washing floor floor pan FP can be arranged at a normal position for placing the wall members WP1 to WP4. The first strut members PC1, PC2 and the second strut members PP1, PP2, PP3 are provided so as to stand on the wall members WP1 to WP4 side (upper side) from the outside of the washing floor pan FP. Since the washroom floor pan FP is stretched, it can be arranged in a state where the plane dimensions of the bathroom unit are maintained. As a result, the wall members WP1 to WP4 can be erected vertically along the first column members PC1, PC2 and the second column members PP1, PP2, PP3, and the wall members and the ceiling panel are attached in close contact with each other. it can. In addition, since there is an extension allowance portion FPr that can be extended in the surface direction inside the wall placement portion FPq of the washing floor floor pan FP, there is less compared with the case where the entire washing floor floor pan FP is stretched and deformed. The washing floor pan FP can be extended in the plane direction by force. In addition, since the extension allowance portion FPr is positively extended, the washing ground floor pan FP can be prevented from being damaged when the washing ground floor pan FP is elongated.

  Moreover, in this embodiment, since correction | amendment part CMa, CMb is provided in the position corresponding to 1st support | pillar member PC1, PC2 and 2nd support | pillar member PP1, PP2, PP3, washroom floor pan FP is made into 1st support | pillar member PC1 ,.

Since the wall surface is pushed out until it comes into contact with at least one of the second column members PP1, PP2, PP3 and the second correction member 12, the water return wall portion FPc can be surely pushed out toward the column member. Since the first straightening member 10 and the second straightening member 12 are fixed by the fixing screws 14, the second washing floor pan FP is attached to the second washing floor FP without providing a mounting hole in the second washing floor pan FP including the water return wall portion FPc. The horizontal projection area can be corrected by reliably extending the column members PP1, PP2, PP3.

  In the present embodiment, the second correction member 12 is attached to the floor support member HP, and the second support members PP1, PP2, PP3 can be indirectly attached to the floor support member HP. . Therefore, since the 2nd correction member 12 can be comprised as an attachment member with respect to the floor support member HP of 2nd support | pillar member PP1, PP2, PP3, the whole structure can be simplified.

  In the present embodiment, since the position restricting portion FPb is provided in the center area on the back surface of the washing area floor pan FP, the positional deviation of the entire washing area floor pan FP in the horizontal direction is restricted based on the position restricting portion FPb in the center area. is doing. Accordingly, the correction parts CMa, CMb will stretch the washing floor pan FP toward the first column members PC1, PC2 and the second column members PP1, PP2, PP3 with the position restriction unit FPb in the center region as a reference. Uneven distribution of the stretching amount on each side can be suppressed. In other words, since the stretch amount on each side of the washing floor floor pan FP can be substantially equalized, the correction work when installing the bathroom unit UB becomes easy.

  Further, as described above, in the bathroom unit UB according to the present embodiment, the first column members PC1, PC2 and the second column members PP1, PP2, PP3 are attached to the floor support member HP, and the washing floor floor pan FP. It is attached so as to stand on the wall members WP1 to WP4 side (upper side) from the outside, and is configured to be detachable from the floor support member HP in a state where the washing floor floor pan FP is arranged on the floor support member HP Has been.

  By being comprised in this way, the washing place floor pan FP can be attached and detached without removing it from the floor support member HP, and its installation position can be changed. Therefore, even if the second column members PP1, PP2, PP3 are attached to the floor support member HP without accurately positioning the column members before the washing floor floor pan FP is arranged on the floor support member HP, Since the installation position of the pan FP can be finely adjusted, the assembly workability of the bathroom unit UB is improved.
