Description

  The present invention relates to a structure of a floor panel used in a sanitary equipment room such as a bathroom.

  What is required for the floor structure of a sanitary equipment room such as a bathroom is the structural strength that can support the load on the floor and the water tightness that prevents the water used in the sanitary equipment room from leaking outside. It is done. And the design of the surface which gives a user comfort, the durability which endures long-term use, and also the lightness in the point of the ease of handling at the time of construction, etc. are calculated | required.

  Conventionally, FRP has been used as a single material to satisfy these requirements. However, this FRP is an advanced composite material, takes a long time for molding, and requires a large work space, so it is expensive, and under the present circumstances, a significant cost reduction cannot be expected.

  In addition, while there are calls for reducing industrial waste and recycling for environmental conservation, FRP is a thermosetting resin and also contains glass fiber, which makes it difficult to dispose of it. is there.

  In this respect, the thermoplastic resin is less expensive than the thermosetting resin, and has an advantage that it can be easily disposed of and reused as a recycled resin because it is melted by heating. Nevertheless, the reason why it was not widely adopted as the floor structure of the sanitary equipment room was mainly due to its inferior strength compared to FRP.

  To solve this problem, you can simply increase the thickness, but this increases your weight. Alternatively, if the thermoplastic resin is reinforced with long fibers such as glass fibers, the strength is increased, but if long fibers such as glass fibers are blended with the thermoplastic resin, recycling becomes difficult.

  Therefore, although it is made of FRP, for the purpose of preventing the bending of the floor pan, it is made into a plate-like member that constitutes the floor of a room such as a bathroom, and a reinforcing rib that falls from the back surface is fixed on the back surface. There is known a floor pan that is provided and has a double-structured structure at least partially by fixing a plate-shaped complementary recessed member of a predetermined size to the protruding end portion of the rib (for example, Patent Document 1). reference.).

  Also, it is also made of FRP, and for the purpose of improving construction workability and ensuring heat insulation, at least the floor pan body having the washing section, the lower end of the washing section is substantially on the same horizontal plane across the entire rear surface side. A floor pan is proposed in which a grid-like rib is provided so as to be located at the bottom, a metal plate is attached to the lower end of the rib over substantially the entire surface, and a leg portion is provided on the back side of the metal plate to support the floor pan body. (For example, see Patent Document 2).

  Furthermore, for the purpose of ensuring strength and heat insulation, the same is made of FRP, and the closed space between the upper surface panel and the lower planar material is filled with foamed resin. A heat insulating floor member is formed between the material and the heat insulating layer, and a wall that closes the periphery of the closed space is formed in a frame shape around the surface panel, and is surrounded by the wall. A plurality of screw fixing points are formed at the same level as the wall at the lower position of the front panel, and an elongated frame is screwed to the screw points via a planar material. There is also a heat insulating floor member provided on the lower surface of the planar material (for example, see Patent Document 3).

  However, in the floor pan described in Patent Document 1, according to the mounting order, the reinforcing member must be fixed to the reinforcing rib before the floor pan is installed on the site. It is the same as a floor pan with a very large thickness, and it is unavoidable to adopt it in a recent sanitary equipment room where a low floor is indispensable to eliminate a step at the entrance of the bathroom from the viewpoint of barrier-free.

  Moreover, in the floor pan of patent document 2, since a metal plate is attached additionally, additional cost starts, and the meaning which employ | adopted the thermoplastic resin cheaply folded is lost.

And in the heat insulation floor member of patent document 3, while providing an elongate base, cost rises and the height of a heat insulation floor member back also becomes large, and is contrary to the request | requirement of a low floor.

The hollow structure includes an upper base portion in which the upper side of the rib and the top plate are integrated, and a lower base portion in which the lower side of the rib and the bottom plate are integrated. Are combined.

  The hollow structure body is not limited to this, and as described in claim 2, the upper base portion in which the ribs and the top plate are integrated and the bottom plate are combined. Alternatively, as described in claim 3, the lower base portion in which the rib and the bottom plate are integrated and the top plate may be combined.

  The hollow structure preferably includes one or more openings penetrating the top plate and the bottom plate and a lid capable of sealing the openings in a watertight manner. Can be slid.

  In addition, the hollow structure is preferably formed using a thermoplastic resin as described in claim 5, more preferably, as described in claim 6. The plastic resin can be slid with the recycled resin.

  According to the floor structure of the sanitary equipment room according to the present invention, the floor of the sanitary equipment room has a sufficient strength without increasing the material used by using an inexpensive material even though the strength is inferior to a conventionally used material. There is an effect that a structure is obtained.

  In addition, the present invention has an effect of obtaining a recyclable sanitary equipment room floor structure.

  An embodiment of a floor structure of a sanitary equipment room according to the present invention will be described with reference to the accompanying drawings, taking a bathroom washroom floor as an example. FIG. 1 is an exploded perspective view showing an overall outline of an embodiment of a floor structure of a sanitary equipment room according to the present invention. The bathroom floor as a sanitary equipment room shown in this embodiment is composed of a washing floor 1 where a bather performs hair washing, body washing, and the like, and a bathtub side floor (not shown) on which the bathtub is placed. The washing floor 1 according to this embodiment is installed on the building floor where the sanitary equipment room is installed, and supports the load of the sanitary equipment room itself and the load loaded in the room, and the sanitary equipment room. And the surface side floor 5 constituting the floor surface.

  As shown in the figure, the floor base portion 2 is divided into a lower base portion 3 and an upper base portion 4, and the lower base portion 3 protrudes upward from the substantially plate-shaped bottom plate 3a and the bottom plate 3a. A plurality of lower ribs 3b. As a result, the lower rib 3b and the bottom plate 3a are integrated and formed into a ribbed box shape in which the lower portion that is subdivided by the lower rib 3b is opened.

  On the other hand, the upper base portion 4 includes a substantially plate-like top plate 4a and a plurality of upper ribs 4b that hang downward from the top plate 4a. As a result, the upper rib 4b and the top plate 4a are integrated and formed into a box shape with a rib that is opened by being divided into small portions by the upper rib 4b.

  The lower rib 3b and the upper rib 4b are provided at positions facing each other, end surfaces 3c and 4c (not shown) are welded together, and the lower base portion 3 and the upper base portion 4 are integrated to form a floor. A base portion 2 is formed.

  At this time, if a plurality of protrusions 3d are provided on one end face 3c and a recessed portion is provided at a position opposite to the other end face, alignment is facilitated. The protrusion and the recessed portion may be upside down.

  In this way, the lower rib 3a and the upper rib 4a are joined to each other, thereby serving as a web that arranges the bottom plate 3a and the top plate 4a with their surfaces facing each other at a certain distance, and accordingly. Without increasing the weight, the physical constant such as the section modulus can be increased and the strength can be increased.

  Thus, the floor base part 2 is formed as a hollow structure having a plurality of hollow spaces HS partitioned by a plurality of ribs by the plurality of lower ribs 3a and the upper ribs 4a.

  The floor base 3 is made of a thermoplastic resin such as polypropylene, ABS, polyethylene, PVC or the like by heat compression molding or the like, and may be newly generated from petroleum or the like. A recycled resin regenerated from the like may be used. Further, when it is no longer used, a reinforcing agent such as glass fiber is not blended so that it can be reused as a resource.

  In addition, the raw material which can be used for this floor base part 3 is various, and if it can be heat-compression-molded, and has a certain amount of strength and is inexpensive, not only a thermoplastic resin but anything can be used. For example, it was obtained by heat compression molding of a laminated chip made by applying a binder such as adhesive to wood chips produced from construction waste wood and thinned wood, mainly waste wood generated at the time of demolishing a house Things can also be used.

  The upper surface of the upper base part 4 forms a base body 4f that forms the floor of the washing place, and includes a wall panel mounting part 4g and a bank part 4h around it. The base main body 4f is provided with a water gradient that descends from the outer peripheral portion having the highest level toward the drain trap 6 provided in the center of the bank portion 4h, and the water used in the washing place is led to the trap 6. From here, it is discharged to the outside through the drain pipe 7.

  The wall panel placement part 4g is formed one step higher than the base body 4f on three sides other than the edge part adjacent to the bathtub side floor of the base body 4f, and the wall panel 11 constituting the wall surface of the bathroom is erected thereon. The

  The bank portion 4h is formed at the edge adjacent to the bathtub-side floor of the base body 4f so as to be one step higher than the base body 4f. On top of this, a bath apron 9 that covers the side of the bathtub is provided, as shown in FIG. Placed.

  The lower rib 3b is provided with cutout portions 3e in some places, and the cutout portions 4e are also provided at positions facing the upper rib 4b. When the lower base 3 and the upper base 4 are joined, the notches 3e and 4e are joined together to form an opening 2a (see FIG. 2).

  A drain trap 6 is housed in one of the hollow spaces HS formed between the lower base portion 3 and the upper base portion 4. As shown in FIG. 2, the drain trap 6 is in contact with the lower surface of the upper base portion 3, is screwed to the upper base portion 3 by the first-stage flange 12, and is further second-stage from above the surface design floor 5 described later. It is fastened together by the flange 13.

  The drain pipe 7 connected to the trap 6 is inserted into the opening 2a described above, and discharges the drainage from the trap to the outside. Since a plurality of openings 2a are provided, it can be connected to an external pipe as a straight pipe as shown by a solid line in FIG. 1, or an external pipe in a different direction via an elbow as shown by a broken line. Can be connected to.

  In addition, the floor base portion 3 according to the present embodiment is formed in a substantially square shape in plan view, and an inspection port AH is provided in the approximate center. Thereby, the connection of the drain pipe 7 becomes easier and the effect that workability and maintainability improve can be acquired. This inspection port AS is watertightly closed by a plate-like lid 8.

  A surface design floor 5 is laid on the upper surfaces of the lid 8 and the upper base portion 4. The surface design floor 5 is a general-purpose resin such as polypropylene and polyethylene, a resin decorative sheet such as a cushion floor material and a soft sheet material used in general construction, and other water-resistant, excellent design, and a surface portion of a bathroom floor. An inexpensive finishing material with the performance that can satisfy the functions of is used. In addition, when sufficient designability is obtained by the upper base floor itself, the surface design floor 5 may be omitted.

  The floor structure of the sanitary equipment room according to the present embodiment is configured as described above. Hereinafter, this floor structure is inserted through the hollow space HS formed between the lower base floor 3 and the upper base floor 4. The merit to be made will be described with reference to FIG.

  In the floor base part 2 of a double floor structure in which a metal plate or the like is attached to the lower end of a rib 2b of a conventional floor structure or a hollow structure, the thickness of the floor base part 2 increases, but interferes with the passage of the drain pipe. The installation height H1 cannot be lowered by cutting out only the portion. Moreover, in order to ensure the drainage gradient, the drainage pipe height h cannot be lowered beyond a certain level. Therefore, the installation height H1 is inevitably increased.

  Therefore, if the drain pipe 7 is piped into the hollow space between the upper base portion 3 and the lower base portion 4 as in the floor structure according to the present embodiment shown in FIG. H2 can be kept small, and the demand for lower floor space can be met.

  Next, a modification of the floor structure of the sanitary equipment room according to the present embodiment will be described with reference to FIG. As schematically shown in FIG. 4A, the floor base portion 2 according to the present embodiment is a rib in which the lower rib 3b and the bottom plate 3a are integrated and subdivided by the lower rib 3b and the lower part is opened. The lower base portion 3 formed in a box shape, and the upper base portion 4 formed in a box shape with ribs in which the upper rib 4b and the top plate 4a are integrated and subdivided by the upper rib 4b are opened. And are formed by welding and bonding.

  However, the method of forming the floor base portion 2 is not limited to this, and as shown schematically in FIG. 4B, the upper portion where the rib 2b and the top plate 4a are integrated and subdivided by the rib 2b is open. The upper base part 4 formed in a box shape with ribs and the lower base part 3 consisting only of the bottom plate 3a may be welded and joined, as schematically shown in FIG. The lower base portion 3 formed into a box shape with ribs, which is formed by integrating the rib 2b and the bottom plate 3a and is subdivided by the rib 2b and is opened at the lower side, and the upper base portion 4 composed only of the top plate 4a are welded and joined. Even if it makes it, the equivalent floor base part 2 can be formed.
