Description

  The present invention relates to a bathroom unit including a bathtub, a washroom floor pan, and a wall member.

  A bathroom unit including such a bathtub, a wall member, and a washing floor floor pan is widely used because it has excellent workability and productivity compared to a so-called conventional bathroom. The bathroom floor pan of a 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. ing.

  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 washing floor floor pan alone has the above-mentioned excellent properties, for example, when assembling a bathroom unit in a high temperature environment, the horizontal projection area of the washing floor floor pan becomes larger than the target dimension, and the wall The circumference of the mounting portion may be larger than the target dimension. In this case, there is a possibility that a gap is generated between the plurality of wall members standing on the peripheral edge of the washing floor floor pan. The bathroom unit is required to have high air tightness and water tightness, and a slight gap between the wall members is also a problem.

  This invention is made | formed in view of such a subject, The objective provides the bathroom unit which can assemble a wall member without a gap, forming a washing-room floor pan using a thermoplastic resin. There is.

  In order to solve the above-mentioned problems, a bathroom unit according to the present invention includes a bathtub, a washing floor pan disposed at a position adjacent to one side of the bathtub, and a plate erected around the bathtub and the washing floor floor pan. A bathroom unit comprising a plurality of wall members formed in a shape, wherein the wash floor pan is formed of a thermoplastic resin, and the wall members are mounted on a peripheral portion of the other side excluding the side along the bathtub. The wall mounting part to be placed is integrally provided, and the horizontal plane projection area of the washing floor floor pan is corrected so that the plurality of wall members can be placed on the wall mounting part at a predetermined interval. Means are provided, and the correction means compresses and deforms the washing floor floor pan in a plane direction.

  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. In addition, the washing floor floor pan is integrally provided with a wall mounting portion for mounting the wall member, so that excellent waterproof performance is maintained by keeping the wall member mounted on the wall mounting portion. It can be demonstrated.

  Furthermore, in the present invention, for example, even when the washing ground floor pan expands in the planar direction under a high temperature environment and the horizontal projection area becomes larger than the target size, the washing ground floor pan is compressed and deformed in the planar direction. In this case, the target horizontal plane projection area can be secured. By configuring in this way, since the circumference of the wall mounting portion becomes the target dimension, a plurality of wall members can be mounted on the wall mounting portion at predetermined intervals, and a floor surface is formed using a thermoplastic resin. However, it becomes possible to assemble the wall member without any gap.

  Further, the bathroom unit according to the present invention includes a floor support member that is disposed below the washing floor floor pan and is formed to have a linear expansion coefficient smaller than the linear expansion coefficient of the washing floor floor pan. Is preferably attached to the floor support member.

  In this preferred embodiment, since the correction means is attached to the floor support member having a smaller linear expansion coefficient than the washing floor floor pan, the position of the correction means does not change even in a high temperature environment and is more stable. It is possible to correct the washing floor pan so that it becomes a predetermined horizontal plane projection area.

Supporting columnar first column members PC1, PC2 and second column members PP1, PP2, PP3 (column members) are provided.

  In FIG. 1, in consideration of the visibility of the drawing, the bathtub BT, the wall members WP1, WP2, WP3, WP4, WP5, WP6, WP7, the first support members PC1, PC2 and the second support members PP1, PP2, PP3 are The outer shape is indicated by broken lines. Any one of the wall members WP1, WP2, WP3, and WP4 is formed so as to be openable and closable as a door member.

  The washroom floor pan FP is formed by foaming a thermoplastic resin. The washing floor floor pan FP is integrally provided with a wall mounting portion FPq on which wall members WP1, WP2, WP3, and WP4 are mounted on the peripheral portion of the other side excluding the side along the bathtub BT. The wall mounting part FPq is a groove-shaped part formed outside the washing floor surface FPp. A water return wall portion FPc is formed on the outside of the wall placement portion FPq so as to stand on the wall members WP1, WP2, WP3, and WP4 side (upper side).

  A drainage pit FPa is formed near the center of the side along the bathtub BT of the washing floor pan FP. The drainage pit FPa is a portion in which a drainage fitting (not shown) is accommodated, and has a protruding portion that protrudes to the floor support member HP side (lower side). A position restricting portion FPb is formed in the central region of the washing floor floor pan FP. The position restricting portion FPb is formed as a protruding portion that protrudes to the floor support member HP side (lower side).

  The floor support member HP is formed to have a linear expansion coefficient smaller than the linear expansion coefficient of the washroom floor pan FP and higher rigidity than the rigidity of the washroom floor pan FP. The floor support member HP is a support member disposed below the washroom floor pan FP. The floor support member HP supports the washing ground floor pan FP by placing the washing ground floor pan FP on the floor support surface HPp.

  A drain pit hole HPa is formed near the center of the side along the bathtub BT of the floor support member HP. The drain pit hole HPa is a hole into which the drain pit FPa is inserted. Accordingly, the drainage pit FPa of the washing floor pan FP is fitted in the drainage pit hole HPa of the floor support member HP, and is thus restrained in the horizontal direction so as to regulate the horizontal displacement.

  A position restricting hole HPb is formed in the center region of the floor support member HP. The position restriction hole HPb is a hole into which the position restriction portion FPb is inserted. Accordingly, the position restricting portion FPb of the washing floor floor pan FP is restrained in the horizontal direction so as to restrict the horizontal displacement by being fitted into the position restricting hole HPb of the floor support member HP.

  Attachment members 2 (pressing portions) are respectively attached to a pair of corner portions on the opposite side of the floor support member HP from the bathtub BT side. The attachment member 2 is a metal fitting for attaching the first column members PC1 and PC2 to the floor support member HP. The attachment member 2 functions as the correction part CMb by being combined with the first support members PC1 and PC2.

  Correction members 12 (pressing portions) are respectively attached to three sides of the floor support member HP other than the side on the bathtub BT side. The correction member 12 is a metal fitting for attaching the second column members PP1, PP2, PP3 to the floor support member HP. The correction member 12 functions as the correction part CMa by being combined with the second column members PP1, PP2, PP3.

  FIG. 2 shows a state where the washing floor pan FP is placed on the floor support member HP. As shown in FIG. 2, when the washing ground floor pan FP is placed on the floor support member HP, the attachment member 2 and the correction member 12 protrude from the upper side to the visible position from the washing ground floor pan FP. The attachment member 2 acts so as to compress and deform the washing floor floor pan FP inward. Similarly, the correction member 12 acts to compress and deform the washing floor floor pan FP inward.

  A state in which the washing floor floor pan FP is compressed and deformed to correct the horizontal projection area will be described with reference to FIGS. 3 and 4. FIG. 3 is a plan view schematically showing the washing floor floor pan FP and the floor support member HP, and shows a state before correction. FIG. 4 is a plan view schematically showing the washing place floor pan FP and the floor support member HP, and shows a state after correction.

  As shown in FIG. 3, in a state before correction, the horizontal plane projection area of the washing floor floor pan FP is configured to be larger than the horizontal plane projection area of the floor support member HP. This is due to the fact that the washing floor pan FP is formed by foam molding of a thermoplastic resin, and even if the horizontal dimension projection area is configured to be large on the initial dimension setting, The horizontal projection area may be increased by shrinkage after molding.

  As illustrated in FIG. 4, the washing floor pan FP is compressed and deformed inward by the straightening section CMa and the straightening section CMb, so that the horizontal plane projection area of the washing floor floor pan FP is corrected to be a predetermined area. More specifically, when the wall members WP1, WP2, WP3, and WP4 are placed on the wall mounting portion FPq formed on the peripheral edge of the washing floor pan FP, the wall members WP1, WP2, WP3, and WP4 are placed. Is corrected to the extent that it can be installed at a predetermined position. Since the washroom floor pan FP is compressed and deformed by the correction unit CMa and the correction unit CMb, the portions where the correction unit CMa and the correction unit CMb are provided are positions where the wall members WP1, WP2, WP3, and WP4 should be originally installed. Until it is shrunk. In the part where the correction part CMa and the correction part CMb are not provided, it is assumed that the washing floor pan FP remains bent outward, but even in that case, the wall members WP1, WP2, WP3 , WP4 are dimensioned so as to enter the wall mounting portion FPq.

  Next, the correction unit CMa will be described with reference to FIG. FIG. 5 is a cross-sectional view showing the vicinity of the correction part CMa. As shown in FIG. 5, the correction part CMa has a correction member 12 and a fixing screw 14. The correction member 12 is fixed to the floor support member HP by a fixing screw 14. The correction member 12 is an L-shaped metal fitting, and is disposed so as to rise along the outer periphery of the floor support member HP.

  Then, as shown in FIG. 6, when the washing floor pan FP is placed on the floor support member HP, the correction member 12 pushes the portion where the wall placing portion FPq and the water return wall portion FPc are formed inward. Act on. As shown in FIG. 6, in the washing ground floor pan FP, a wall placing portion FPq is formed in a groove shape around the washing ground floor FPp. Therefore, the wall mounting portion upper surface FPd, which is the lower surface of the groove of the wall mounting portion FPq, is formed so as to be positioned below the washing floor surface FPp.

  Subsequently, as shown in FIG. 7, the second support member PP <b> 1 (PP <b> 2, PP <b> 3) is fixed to the correction member 12. An engagement protrusion PPa is formed at the lower end of the second support member PP1. When the second support member PP1 is fixed to the correction member 12, the water return wall portion FPc is sandwiched and fixed between the correction member 12 and the engagement protrusion PPa.

  In the present embodiment, the horizontal floor projection area of the washing ground floor pan FP is formed to be larger than the horizontal plane projection area of the floor support member HP, and the washing ground floor pan FP is compressed and deformed along the horizontal plane by the correction portions CMa and CMb. By doing so, the horizontal projection area of the washing floor pan FP is corrected. The degree of correction does not necessarily need to be corrected to the extent that the horizontal projection area of the floor support member HP and the horizontal projection area of the washing floor floor pan FP completely coincide with each other, as long as the wall members WP1 to WP4 can stand up without any trouble. It is enough. Therefore, the wall members WP1 to WP4 need only be able to stand up even when a part of the washing floor pan FP is positioned outside the floor support member HP. One example will be described with reference to FIG.

  FIG. 8 is a schematic plan view showing a state in which the washing floor floor pan FP protrudes between the correction sections CMa and CMb, although a part of the washing floor floor pan FP is corrected by the correction sections CMa and CMb. FIG. The AA cross section of FIG. 8 is shown in FIG. 9, and the BB cross section of FIG. 8 is shown in FIG.

  Since the part shown in FIG. 9 is a part corresponding to substantially the middle between the correction part CMa and the correction part CMb, the force to push the wash floor pan FP inward is the weakest. Therefore, the washing floor floor pan FP is located outside the floor support member HP. As shown in FIG. 9, the width of the wall placing portion upper surface FPd in the wall placing portion FPq is configured to be sufficiently wider than the thickness of the lower end of the wall member WP1. Therefore, even if the washing floor floor pan FP is displaced outward, the wall member WP1 contacts the inside of the wall placing part FPq and fits inside the wall placing part FPq.

  On the other hand, since the part shown in FIG. 10 is a part close to the correction part CMb, the force to push the wash floor pan FP inward becomes strong. Accordingly, the wash floor pan FP is located inside the floor support member HP. As shown in FIG. 10, the width of the wall placing portion upper surface FPd in the wall placing portion FPq is configured to be sufficiently wider than the thickness of the lower end of the wall member WP1. Therefore, even if the washing floor pan FP is displaced inward, the wall member WP1 comes into contact with the outside of the wall placing part FPq and is accommodated in the wall placing part FPq.

  In the above-described embodiment, although the correction part CMa and the correction part CMb are partially provided as correction means for compressing and deforming the washing floor pan FP inward, the wall members WP1 to WP4 can be erected without hindrance. If it is, it will not be restricted to this aspect. For example, it is also preferable that the outer periphery of the floor support member is raised over three sides on which the wall members WP1 to WP4 are disposed, and the washing floor pan FP is compressed and deformed inward.

  As described above, in the present embodiment, the washing floor floor pan FP is a horizontal plane projection region larger than the floor support member HP so that the peripheral edge portion is located outside the support members PP1, PP2, PP3. A large size is formed in advance. A part of the wall mounting portion FPq corresponding to the first column members PC1, PC2 and the second column members PP1, PP2, PP3 is brought into contact with the first column members PC1, PC2 and the second column members PP1, PP2, PP3. Thus, the correction parts CMa and CMb are provided as correction means for correcting the horizontal plane projection area of the washing floor floor pan FP.

  According to the present embodiment, since the washing floor floor pan FP 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 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 where 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.

  Further, in the present embodiment, for example, even if the washing floor floor pan FP contracts, the washing floor floor pan FP is formed to be sufficiently larger than the target horizontal plane projection area so that the target horizontal plane projection area can be secured. By compressing and deforming, a target horizontal projection area can be secured. For this reason, since the circumference of a wall mounting part becomes a target dimension, a plurality of wall members can be mounted on a wall mounting part at a predetermined interval, and a wall is formed while forming a floor surface using a thermoplastic resin. It becomes possible to assemble the members without gaps. Further, a part of the wall mounting portion FPq corresponding to the first support members PC1, PC2 and the second support members PP1, PP2, PP3 is applied to the first support members PC1, PC2 and the second support members PP1, PP2, PP3. Since it is compressed and deformed so as to contact, the wall mounting portion FPq of the washing floor pan FP at the position corresponding to at least the first column members PC1, PC2 and the second column members PP1, PP2, PP3 is changed to the wall members WP1 to WP1. It can be arranged at a regular position for placing 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-WP4 side from the outside of the washing floor pan FP. Since the washroom floor pan FP is compressed and deformed inside the second support members PP1, PP2, PP3, it can be arranged in a state where the plane dimensions as a 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.

  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 ,. It can be surely compressed and deformed to a target position at positions corresponding to the PC 2 and the second support members PP1, PP2, PP3. Therefore, in the place where 1st support | pillar member PC1, PC2 and 2nd support | pillar member PP1, PP2, PP3 are arrange | positioned, wall member WP1-WP4 can be reliably arrange | positioned in a regular position. Further, the wall members WP1 to WP4 do not enter inside between the first column members PC1 and PC2 and the second column members PP1, PP2 and PP3, and as a result, the wall members WP1 to WP4 are brought into their normal positions. Can be erected. Accordingly, without providing the correction portions CMa and CMb around the washing floor pan FP so as to surround the washing floor floor FP, the horizontal plane projection area of the washing floor pan FP is corrected, and the wall members WP1 to WP4 are replaced with the first support members PC1, PC2 and It can stand upright along 2nd support | pillar member PP1, PP2, PP3.

  Moreover, in this embodiment, the upper end of the mounting member 2 and the correction member 12 functioning as a pressing portion that compresses and deforms by pressing the peripheral edge of the washing floor pan FP inward is approximately equal to or higher than the wall mounting portion FPq. Since the floor support member HP is provided so as to protrude, the washing floor floor pan FP is more reliably brought to the target position at a position corresponding to the first column members PC1, PC2 and the second column members PP1, PP2, PP3. It can be compressed and deformed. Accordingly, the wall members WP1 to WP4 can be more reliably disposed at the regular positions at the positions where the first column members PC1, PC2 and the second column members PP1, PP2, PP3 are disposed.

  Moreover, in this embodiment, since the wall mounting part upper surface FPd of the wall mounting part FPq is formed at a position lower than the washing floor surface FPp, the lower ends of the wall members WP1 to WP4 can be reliably positioned. . In particular, it is a case where the wall placing part FPq remains inflated outward along the washing floor surface FPp between the first strut members PC1, PC2 and the second strut members PP1, PP2, PP3. Since the width of the wall mounting portion upper surface FPd is wider than the thickness of the lower ends of the wall members WP1 to WP4 so that the lower ends of the wall members WP1 to WP4 are in contact with the wall mounting portion upper surface FPd, the wall The wall members WP1 to WP4 can be erected reliably regardless of the degree of deformation of the placement portion FPq.

  In the present embodiment, the correction portions CMa and CMb are attached to the floor support member HP, and the first support members PC1 and PC2 and the second support members PP1, PP2 and PP3 are attached indirectly to the floor support member HP. It is configured to be able to. Accordingly, the correction portions CMa and CMb can be configured as attachment members for the floor support member HP of the first column members PC1 and PC2 and the second column members PP1, PP2 and PP3, thereby simplifying the overall configuration. Can do.

  Moreover, in this embodiment, since the drainage pit FPa which protruded to the floor support member HP side is formed in the bathtub BT side peripheral part of the washing ground floor pan FP, the washing ground floor pan FP in the horizontal direction on the basis of this drainage pit FPa The overall position shift is regulated. Therefore, since the correction parts CMa and CMb compress and deform the washing floor pan FP on the basis of the drain pit FPa, the bathtub BT side where the correction parts CMa and CMb are not arranged is positioned without using a special member. be able to.
