Description

  The present invention relates to a method for constructing bathroom equipment.

  As a renovation work of an aging bathroom, a unit bath (system bus) for assembling unitized precast panels in the bathroom may be adopted. Renovation work using unitized panels requires less work on site than conventional methods using tiles and the like, and the time required for curing can be omitted, making the work simple and quick. be able to.

  On the other hand, the panel of the unit bus generally has a standardized shape (mainly rectangular shape in plan view). Therefore, when adopting in an existing bathroom with a unique shape and size, such as a shape corresponding to a shape with uneven walls and a shape in which the opposite wall is not parallel, the original bathroom (body) It is necessary to adopt a unit bath smaller in size than the area. When a small-sized unit bath is used, a useless space is formed on the back surface of the panel (between the panel and the frame).

  Therefore, Patent Literature 1 discloses a retrofitting method in which a gantry is fixed in a bathroom using a fixture capable of adjusting dimensions, and a bathtub waterproof pan and a washing pan are placed on the gantry. Further, Patent Literature 2 discloses a bathroom remodeling method in which a ceiling height of a unit bath is adjusted to a ceiling height of a frame by adding a reinforcing panel on a wall panel.

  The refurbishment method of Patent Document 1 makes it possible to install a panel using a gantry, but does not adjust the size of the panel itself. Therefore, the space formed on the back surface of the panel cannot be effectively used. Further, in Patent Literature 1, it takes time and effort to adjust the fixing device performed on site.

  Further, in the remodeling method of Patent Literature 2, the direction in which the width can be increased by using the additional panel is limited to only the upward direction. Therefore, the floor area of the unit bath could not be increased. In addition, it takes time and effort to add the additional panels at the site.

  From this point of view, the present invention is a unit bath (system bus) that has a dimensional shape adapted to a local shape, thereby effectively utilizing space, and having excellent design, durability and heat insulation. It is an object of the present invention to propose a method of constructing a bathroom facility that enables a simple construction of a bathroom.

  In order to solve the above-mentioned problems, a method for constructing a bathroom facility according to the present invention uses a 3D scanner to measure the shape and dimensions of a bathroom (body) to obtain measurement data, and a measurement step based on the measurement data. The method includes a molding step of molding a plurality of unit bath parts adapted to the bathroom using a 3D printer, and an assembling step of assembling the parts in the bathroom to form a unit bath.

  According to such a bathroom equipment construction method, a unit bus (system bus) corresponding to the shape of the site (body) is formed because a part having a shape based on the measurement result of the 3D scanner is formed using a 3D printer. can do. Therefore, no useless space is formed between the parts and the bathroom wall surface (the back of the parts), and the space as the bathroom can be utilized to the maximum. Further, even if the shape is special, it can be formed into a shape suitable for the site. Further, even when a unit bath is formed in combination with a ready-made panel (ready-made panel) or a ready-made bathtub, parts having a shape or a design corresponding to the ready-made panel or bathtub can be formed.

  In the case where the part is formed of a hollow member made of resin, if the filling step of filling the part with a filler is performed after the assembling step, the weight of the part can be reduced during transport and during assembly. Therefore, parts can be handled more easily, and workability during transportation and installation is further improved. As the filler, it is desirable to use a material having sufficient heat insulation properties and necessary strength. For example, a cement-based material such as mortar or cement paste, or a urethane resin may be used.

In the molding step, if a part of a unit bath designed based on the measurement data is molded, a unit bus having an original shape and function according to the local situation (shape) can be formed. it can.
In addition, if the parts constituting the bathtub can be separated from other parts, only the bathtub can be replaced after construction.

  According to the construction method of the bathroom equipment of the present invention, it is possible to form a unit bath part having a dimensional shape according to the measured value of the bathroom, so that it is possible to easily construct a unit bath capable of effectively utilizing the space. is there.

  In the present embodiment, in the refurbishment work of the bathroom 1, a part (panel) 2 formed according to the frame shape of the bathroom 1 is used to make full use of the space for the bathroom 1 in a bathroom facility. The construction method will be described (see FIG. 1). The method for installing the bathroom equipment includes a preparation step, a measurement step, a molding step, an assembly step, a filling step, and a surface treatment step.

In the preparation process, existing equipment in the bathroom 1 is removed. For example, in a bathroom constructed by a conventional construction method, existing tiles and the like are removed to expose the frame (the floor slab 11, the wall surface 12, and the like) of the bathroom 1. At this time, hot water supply facilities, bathtubs and the like may be removed. If there are any hot water supply facilities or bathtubs that will be used continuously, leave them there. If the removal of existing tiles or the like may have an adverse effect on the nearby living environment such as noise and vibration of the removal work, a part of or removal may not be performed and the process may proceed to the next process.
When all of the existing floor finishing tiles and the like are removed, the ceiling height of the bathroom can be increased by the thickness of the removed portion, so that a wider space can be provided. In this case, since the floor slab is exposed entirely flat, the shape of parts laid by the 3D printer is simplified, and construction efficiency and assembly accuracy can be improved.
On the other hand, when proceeding to the next process without removing or removing some of the existing tiles, etc., there is little or no noise, vibration, dust, etc. associated with the removal work. The adverse effects on the living environment can be minimized.

  In the measurement step, as shown in FIG. 2, the 3D scanner 3 is used to measure the shape and dimensions of the bathroom 1 (body) from which the existing equipment has been removed. The 3D scanner 3 is installed at the center of the bathroom 1 and measures the entire interior of the bathroom 1. The arrangement of the 3D scanner 3 at the time of measurement is not limited. Further, the model and measuring method of the 3D scanner 3 are not limited. The data measured by the 3D scanner 3 is taken into processing means (computer) 4 provided in a panel manufacturing factory or the like via communication means (see FIG. 3). Note that the measurement data may be taken into the processing means 4 via a storage medium (for example, a memory card or a USB memory). The location where the processing means 4 is installed is not limited to this, since wireless communication or the like may be used in some cases. If there is a continuous use of various facilities such as hot water supply facilities and bathtubs, measure around the remaining facilities.

  In the molding step, first, the unit bus 20 (part 2) is designed based on the measurement data taken into the processing means 4. In addition to the design inside the bathroom 1 of the unit bath 20, the number of divisions of the part 2 (unit bath 20) (for example, 2 to 4 parts of the floor panel 21), the division (joining) location of the part 2, and the like are designed. It is desirable that the bathtub 22 and the floor panel 21 be configured to be separable so that the bathtub 22 can be changed according to the resident's request (see FIG. 1). Further, the bathroom 1 may be provided with handrails, shelves, and the like as necessary. When designing the unit bus 20, a standardized design may be adopted to adjust the dimensions according to the local shape (measured value), or a new design according to the local shape may be designed. Good. The unit bus 20 can be freely designed on the front side (indoor side), but the back side (body side) has a shape corresponding to the local shape (measurement data).

Next, a plurality of parts 2 are formed using a 3D printer 5 provided in a panel manufacturing factory or the like (see FIG. 3). The 3D printer 5 is connected to the processing unit 4 by wire or wirelessly, and manufactures the parts 2 based on the design data (design data) transmitted from the processing unit 4. Note that the design data may be taken into the 3D printer 5 using a storage medium (for example, a memory card or a USB memory). The part 2 has a shape adapted to the bathroom 1 by being designed based on measurement data of the bathroom 1. As shown in FIG. 4, the part 2 of the present embodiment is a hollow member made of resin, but the part 2 may be a solid member. The material constituting the part 2 is not limited. For example, a UV curable acrylic polymer generally used for a 3D printer or a metal material (SUS316L, chromium molybdenum steel, copper, Inconel, Kovar) compatible with a 3D printer is used. Etc.) should be used. In particular, in manufacturing the part 2 of the unit bath 20 having excellent design, a UV-curable acrylic polymer is preferable from the viewpoints of later painting, coating, slip prevention, heat insulation, waterproofing, corrosion resistance, and the like.
In the present embodiment, the thickness of the part 2 (the distance from the front surface to the back surface) is set so that the floor panel 21 has a thickness of 5 to 100 mm, the bathtub 22 has a thickness of 80 to 200 mm, and the wall panel 24 and the ceiling have a thickness of 5 to 100 mm. Although it is within the range of 100 mm, the thickness of the part 2 is not limited. In addition, in order to ensure the filling property of the filler 6, it is desirable that the thickness of the inner space is 3 mm or more, more preferably 30 mm or more.

  The part 2 includes a pair of shell plates 2a covering the front and back surfaces, a side plate 2b covering the periphery (outer edge of the pair of shell plates 2a), and a plurality of shell plates 2a connecting the shell plates 2a between the pair of shell plates 2a. And a reinforcing member 2c. In the present embodiment, the columnar reinforcing members 2c are arranged in a staggered manner, but the shape of the reinforcing members 2c is not limited, and may be, for example, a plate-like member (rib). The reinforcing material 2c does not hinder the flow of the filler 6 when filling the filler 6, and also enables the deformation of the part 2 to be suppressed by the pressure at the time of filling the filler 6. Are located.

  A plurality of projections (legs 23) are formed on the lower surface of the floor panel 21 and the bathtub 22, and a gap for piping (for example, a height of 150 mm or less) is provided between the floor slab 11 of the skeleton and the lower surface of the part 2. (200 mm). By doing in this way, the position of the drain hole of the unit bath 20 can be freely arranged without adjusting to the position of the old drain pipe 13 piped in the building. When the old drain pipe 13 installed in the building is not used, the drain pipe 7 that is individually connected to the main pipe 14 can be newly installed. The leg 23 of the part 2 may be formed as needed, and may be omitted if no space for piping is required between the lower surface of the unit bath 20 and the floor slab 11.

  In the assembly process, as shown in FIG. 5, the parts 2 are assembled in the bathroom 1 to form the unit bath 20. The parts 2 formed outside the building are carried in and assembled in the bathroom 1. The part 2 has a shape that can be carried in from the entrance of the bathroom 1. Since the part 2 is made of resin, it may be slightly bent when passing through a door or the like. When the parts 2 are arranged at predetermined positions, welding (welding) is performed at a joint (butting part) between the parts 2. The joining structure between the parts 2 is not limited as long as the waterproofness can be ensured. For example, the parts 2 may be welded to each other, or may be bonded via a sealant or a waterproof adhesive.

In the filling step, as shown in FIG. 6, the inside of the part 2 (the space surrounded by the shell plate 2a and the side plate 2b and the legs 23) is filled with the filler 6. In this embodiment, mortar is used as the filler 6. In addition, the material used for the filler 6 is not limited, but is preferably a material having a predetermined strength and having heat insulating properties. As such a material, besides mortar, particularly cellular mortar for improving heat insulation, cement-based materials such as cement paste and concrete, and resin-based materials such as urethane resin and epoxy resin can be used. In particular, a material having a high elastic modulus is preferable in order to prevent dents and deformation of the filled hollow member with the lapse of time from the viewpoint of economy, and a cement-based material is preferable from this viewpoint. In addition, it is advantageous that, even in a cement-based material, a heat insulating property can be imparted while maintaining an elastic modulus by mixing 5 to 50%, more preferably 10 to 30% of a foamed cement mortar with respect to a filling volume. is there.
In addition, different materials may be used for the filler 6 depending on the location of the part 2. For example, as the filler 6 to be filled in the bathtub 22, a material having a higher heat retention than the filler 6 to be filled in the floor panel 21 is used, and as the filler 6 to be filled in the floor panel 21, a part such as a ceiling or a wall is used. A material having a higher strength than the filler 6 to be filled in 2 may be used.

The filler 6 is press-fitted through an injection hole 2d formed in the part 2 via a pump. Each part 2 has an air vent hole 2e formed at a position away from the injection hole 2d. The filling material 6 is injected until the outflow of the filling material 6 from the air vent hole 2e can be confirmed. Note that the air vent hole 2e may be formed as needed. When the filler 6 is injected, the injection hole 2d and the air vent hole 2e are shielded, and then the filler 6 is cured until it hardens.
The positional relationship between the injection hole 2d and the air vent hole 2e may be such that the filler 6 is arranged so as to spread over the entire inside of the hollow part. However, it is preferable that the injection hole 2d is about 1 to 10 mm larger than the air vent hole 2e. It is preferably located at a low position, for example, a rectangular part 2 is arranged diagonally. Further, a hose of about 10 cm or the like is connected to the air vent hole 2e in an open state upward, and the filler sent from the injection hole 2d eventually overflows from the hose, and the air inside is completely removed. If the process is controlled to discharge, a reliable filling operation can be performed.

  In the surface treatment step, the surface treatment of the unit bath 20 (part 2) is performed. That is, a surface treatment is performed so as to ensure impact resistance, abrasion resistance, slip resistance, water repellency, quick drying property, and antibacterial property. The surface treatment method is performed by, for example, coating or polishing the surface of the part 2.

  As described above, according to the bathroom installation method of the present embodiment, since the part 2 (panel) having the shape based on the measurement result of the 3D scanner 3 is formed by the 3D printer 5, the unit according to the shape of the site (body) is used. A bus 20 (system bus) can be formed. Therefore, no useless space is formed on the back surface of the part 2 and the space as the bathroom 1 can be utilized to the maximum. Further, even if the shape is special, it can be formed into a shape suitable for the site.

Since the part 2 is molded using the 3D printer 5, the degree of freedom in design is high. Therefore, the unit bath 20 in which the bathtub 22 is separated from other parts (the floor panel 21, the wall panel 24, and the like) is formed, and the bathtub 22 is integrated with the floor (the floor panel 21) and the wall (the wall panel 24). The molded unit bus 20 can be formed. Further, it is also possible to form a bathroom 1 having a design corresponding to a ready-made bathtub having a special shape. Further, the design in consideration of the existing piping and air-conditioning equipment, and the expansion of piping and air-conditioning can be freely designed.
By adjusting the member thickness of the part 2 (thickness of the filler 6) and selecting the material of the filler 6, heat insulation according to the performance of the area or the building can be ensured.

As described above, the embodiments of the present invention have been described, but the present invention is not limited to the above-described embodiments, and each of the above-described components can be appropriately changed without departing from the spirit of the present invention.
For example, a ready-made product may be separately carried into a bathtub and used, and the other parts may be formed by adopting the bathroom equipment construction method of the present invention.

  The method of assembling the parts 2 is not limited. For example, the parts 2 may be assembled in the order of a floor panel 21 (floor part), a wall panel 24 (wall part), and a ceiling part (not shown). The floor panel 21 may be assembled after the ceiling is assembled. Further, after the assembling process of the floor portion (floor panel 21) and the filling process are completed, the assembling process of the wall portion (wall panel 24) and the ceiling portion may be started.

  The adjacent parts 2 may be continuous or separated from each other. If the inner cavities of the parts 2 are continuous with each other, it is possible to fill the plurality of parts 2 with the filler 6 from one injection hole 2d, and to ensure the integrity of the parts 2 Can be. On the other hand, if the inner space is separated for each part 2, by simultaneously filling the plurality of parts 2 with the filler 6, it is possible to achieve early construction, and in the case where damage occurs, the parts 2 2 can be partially replaced. The inner space of the part 2 may be internally divided into a plurality of parts.

  In the above embodiment, the case where the processing unit 4 and the 3D printer 5 are installed in the same place (panel manufacturing factory) has been described. However, the installation locations of the processing unit 4 and the 3D printer 5 are not limited, It may be installed in a different place. For example, the design may be designed in the processing means 4 such as a design office, and the part 2 may be formed by the 3D printer 5 installed in an office or warehouse near the site.

  The unit bath 20 may be formed only of the parts 2 formed according to the body shape of the bathroom 1, or may be formed by combining a ready-made product (a ready-made panel or a ready-made bath tub) with the part 2. . When the unit bus 20 is formed by combining the ready-made product and the part 2, the data of the ready-made product to be used is input when designing the part 2 in the molding process, and the shape of the part 2 that can be combined with the ready-made product is input. And design. In the measurement step, when the measurement is performed in a state where the ready-made product is placed in the bathroom 1, the part 2 that can be combined with the ready-made product may be designed based on the measurement result.
