In order to solve the aforementioned problems, the bathroom floor structure of the present invention is characterized by having: Shelf, which is set at the bottom of the bathroom floor; Floor laying body, which is laid on the aforementioned platform; and A drainage pool, which extends from one end to the other end of one direction of the bathroom along one side of the floor laying body; and The drainage pool and the floor-laying body are separate structures from each other, and are independently supported by the gantry.

According to this bathroom floor structure, the drainage pool and the floor paving body can be separately installed on the stand. Therefore, even if the drainage tank has a large capacity, installation work can be easily performed. Conversely, the capacity of the drainage tank can be increased without being limited by the operability of installation. In addition, since the floor laying body and the drainage pool can be separately provided, the piping and connection work can be easily performed by, for example, piping the drain pipe and the drainage trap under the floor and connecting it to the drainage pool before installing the floor laying body Change. After that, the floor paving body is installed on the gantry.

Preferably, the platform includes a pair of floor beams extending along a pair of long side edges of the drainage basin; and The drainage pool is suspended between the pair of floor beams, and supported by the floor beams corresponding to the long side edges. If the drainage pool is inserted between a pair of floor beams and the floor beam is placed on a pair of long side edges of the drainage pool, even before the drainage pool is joined and fixed to the gantry, the drainage pool can be stably suspended on shelf. Thereby, the installation operation of the drainage tank can be further facilitated. By setting the drainage tank to the above-mentioned suspension structure, the depth, width, and length of the drainage pool can be sufficiently increased, thereby ensuring a large capacity.

It is preferable that the drainage pool and the floor paving body are supported or connected to mutually spaced portions of the floor beams that are common to each other. Thereby, the installation work of the drainage pool and the installation work of the floor laying body can be performed separately. The drainage pool and the floor paving body can be supported or connected to one floor beam without interference. The part of the drainage pool that applies the load to the floor beam and the part connected and fixed to the floor beam can be separated from each other and set separately. The portion of the floor paving body that applies a load to the floor beam and the portion connected and fixed to the floor beam can be separated from each other and provided separately.

Thereby, the connection between the drainage pool and the floor beam and the connection between the floor paving body and the floor beam can be separated from each other without interference.

Preferably, a convex wall portion extending along the long side edge is formed in the drainage basin, a groove is defined between the convex wall portion and the floor paving body, and the protruding edge is disposed at the bottom of the groove unit; The spacer member is accommodated in the groove so as to cover the protruding edge; The end of the surface layer sheet of the floor covering body spans the upper surface of the spacer member and covers the upper surface of the rib wall portion. If one of the drainage pool and the floor laying body is installed on the gantry and connected with the floor beam, and the other is installed on the gantry, a groove is formed between the convex wall of the drainage pool and the floor laying body, At its bottom, a connecting seat protruding from the edge and a recessed recess appear. Thereby, the connection operation between the drain pool and the floor paving body and the floor beam can be performed through the aforementioned groove. After that, the groove is blocked with a spacer member and covered with a surface sheet.

Preferably, the floor beam includes an inverted U-shaped cross-sectional upper side beam member having an upper plate and a pair of side plates, and a U-shaped cross-sectional lower side beam member having a lower plate and a pair of side plates. The upper and lower beam members are fitted with each other so that their side plates overlap. Thereby, the flexural strength of the floor beam can be increased, and the large-capacity drainage pool and floor paving body can be reliably supported.

Preferably, the drainage pool includes a long first pool and a short second pool arranged in a straight line along the extending direction, and the first and second pools are abutted and connected with a water-tight material therebetween. By combining pools with different lengths, the total length of the drainage pool can be adjusted corresponding to the various sizes of the bathroom.

Preferably, a relatively long wall/door receiving frame portion for receiving the wall panel of the bathroom or the door frame is provided along the outer peripheral portion of the floor laying body; A relatively short wall/door receiving frame portion is provided at the short-side end edge of the aforementioned drainage tank; The aforementioned long/short wall/door receiving frame portions are connected to each other via a connecting device. By this, not only along the outer peripheral part of the floor paving body, but also along the short edge of the drainage pool, a bathroom wall panel or a door frame can be provided. The drainage pool and the floor laying body can be connected via the wall/door receiving frame part.

Preferably, the aforementioned connection device includes: The first connecting part, which has an engaging member and an operating member, and is provided on one of the aforementioned long/short wall/door receiving frame portions; and The second connecting part, which is provided on the other of the aforementioned long/short wall/door receiving frame; and By the operation of the operation member, the engagement member can be raised and lowered between the disassembly position and the restraint position; The second connecting component and the engaging member at the disassembly and assembly position are detachable, and the second connecting component is constrained by the engaging member at the constraining position so that they cannot be separated from each other. By setting the engaging member at the detachable position and engaging with the second connecting part, and then operating the operating member, the engaging member is moved toward the restraining position. As a result, the engagement member and the second connection part are constrained so as not to be separated. As a result, the floor paving body and the wall/door receiving frame portion of the drainage pool can be easily and firmly connected to each other. The operating member preferably appears on the upper surface of the first connecting part. Thereby, the operation member can be operated from above. For example, even if the structural wall is arranged close to the outside of the bathroom in a plan view, the operation member can be operated without any trouble.

As shown in FIGS. 14 and 15, when the engaging member 12 is in the detachable position, the engaging protrusion 23 can be inserted into and removed from the receiving hole 15 a, and the engaging protrusion 23 can be detached from the engaging member 12. As shown in FIGS. 10 and 11, when the engaging member 12 is at the restraining position, the protruding shaft portion 24 of the engaging protrusion 23 passes through the restraining groove 15 b, and the shaft head 25 presses against the flat top surface 16 a of the restraining protrusion 16 While being constrained. As a result, the first and second connecting parts 10 and 20 are inseparably engaged with each other, and the wall/door receiving frame portions 2f and 4f are inseparably connected with each other. Furthermore, the watertight material 52 between the side plate 11b and the wall/door receiving frame portion 2f is compressed to perform waterproofing treatment. In the assembled bathroom floor 1a, the engaging member 12 is arranged at the restraining position. In addition, as shown in FIG. 1, the wall/door receiving frame portion 2 f of the floor panel 5 adjacent in the bathroom width direction is connected to each other via a connection device 9B similar to the aforementioned connection device 9.

As shown in FIG. 13, when constructing the bathroom floor 1a on the construction site of the building structure, first, the stand 3 is provided. Secondly, a drainage pool 4. Two (plural) pools 4a, 4b may be connected in advance in a factory or the like, or may be connected at the construction site. By combining the pools 4a and 4b with different lengths, the total length of the drainage pool 4 can be adjusted according to various sizes of the bathroom 1. The pool body 40 of the drainage pool 4 is inserted between two central floor beams 33, and a pair of long frame portions 41 are placed on the corresponding central floor beams 33, respectively. Thereby, the drainage pool 4 is suspended between two central floor beams 33. If the long frame portion 41 is placed on the floor beam 33, even before the drainage tank 4 is joined and fixed to the gantry 3, the drainage pond 4 can be stably supported by the gantry 3. Then, the pool fixing screw 47 is screwed into the central floor beam 33 through the connection seat 44a, and the drain 4 is fixed to the gantry 3. Since the drainage tank 4 is suspended steadily and supported between the central floor beams 33, the fixing operation using the pool fixing screws 47 can be easily performed. Furthermore, at this stage, since the floor panel 5 has not yet been installed, it is indeed possible to facilitate the installation work of the drain 4. Even if the drainage pool 4 is a large-capacity large-scale pool, the operability of the installation is not impaired. Conversely, the capacity of the drainage tank can be increased without being limited by the operability of installation.

Next, the drain trap 4d is arranged below the drain tank 4 and connected to the drain port 4c. Furthermore, the drain pipe 4e connected to the drain well 4d is piped to the bathroom under-floor space 1b below the horizontal floor beam of the gantry 3. At this stage, since the floor panel 5 has not been installed, and the under-floor space 1b of the bathroom is opened, the connection operation of the drain well 4d and the piping operation of the drain pipe 4e can be easily performed. Even if the drain trap 4d is large in size and the drain pipe 4e is large in diameter, it does not cause obstacles to connection and piping operations.

Next, a plurality of floor panels 5 are provided on the trestles 3 on both sides via the drainage pool 4. The foot 5d of each floor panel 5 is placed on the central floor beam 33. Furthermore, the panel fixing screw 5h is used to connect the connecting tab 5g to the central floor beam 33. By this, the bathroom floor panel 5 is fixed to the stand 3. As shown in FIG. 5, at this stage, since the connecting tab 5g appears at the bottom of the groove 48, the screwing operation of the panel fixing screw 5h can be easily performed. It is even possible to connect the bathroom floor panel 5 and the stand 3. A plurality of bathroom floor panels 5 are arranged on the gantry 3 in the same procedure, and the adjacent wall/door receiving frame portions 2f of the floor panel 5 are connected to each other via a connecting member 9B.

In addition, the wall/door receiving frame portion 2f of the floor paving body 2 and the wall/door receiving frame portion 4f of the drainage pool 4 are connected as follows. As shown in FIG. 14, the engaging member 12 of the connection device 9 is arranged at a detachable position in advance. Then, as shown in FIG. 14 to FIG. 15, the frame portions 2f and 4f are horizontally opposed to each other, close to each other, and abut. Along with this, the engaging protrusion 23 is received by the receiving hole 15a. Then, by operating the operating member 13, as shown in FIGS. 10 and 11, the engaging member 12 is raised to the restraint position. By arranging the head 13a of the operation member 13 on the upper plate portion 11c of the holder member 11, the operation member 13 can be easily screw-operated from above. Therefore, even if the structural wall 8 and the like are arranged close to the outer side of the bathroom floor 1a in plan view, it does not hinder the operation of the operating member 13. As the engaging member 12 rises toward the restraining position, the protruding shaft portion 24 of the engaging protrusion 23 is transferred from the receiving hole 15a to the restraining groove 15b. Furthermore, as shown enlarged in FIGS. 17(a) to 17(b), the shaft head 25 faces the wall/door receiving frame portion 4f side along the inclined guide surface 16b of the restraining ridge 16 (in FIG. Left side in 17) The pressed side moves toward the flat top surface 16a side. Along with this, the engagement protrusion 23 is drawn even toward the wall/door receiving frame portion 4f side of the wall/door receiving frame portion 2f.

When the engaging member 12 reaches the restraining position, the shaft head 25 climbs up the flat top surface 16a of the restraining raised portion 16 and is strongly pressed toward the wall/door receiving frame portion 4f side. Therefore, a strong pressing force or a pulling force acts on the engaging protrusion 23 and even the wall/door receiving frame portion 2f toward the frame portion 4f side. Thereby, the wall/door receiving frame portions 2f and 4f can be firmly joined to each other via the connection device 9. Then, the watertight material 52 is strongly compressed. As a result, the waterproof ability of the watertight material 52 can be reliably expressed, and the first connection member 10 and the wall/door receiving frame portion 2f can be reliably sealed.

Thereafter, as shown in FIG. 13, the spacer member 49 is accommodated in the groove 48. Furthermore, the laying of the surface layer sheet 6, the installation of the wall panel 7 and the not-shown door frame, etc. are performed. As shown by the two-dot chain line in FIG. 10, the bottom of the bathroom wall panel 7 (or door frame) is not only embedded in the wall/door receiving concave portion 2g of the frame portion 2f of the floor paving body 2, but also in the frame portion 4f of the drainage basin 4 The wall/door receiving recess 4g is further fitted into the wall/door receiving recess 11g of the connection device 9 (see FIG. 11). Therefore, the operating member 13 can be hidden by the bathroom wall panel 7 (or door frame).

According to this bathroom floor structure, by setting the floor paving body 2 and the drainage tank 4 as separate structures as described above and independently supported by the gantry 3, the installation work of the drainage pool 4 and the floor laying body can be performed separately 2. Set up the job. Therefore, even if the drainage tank 4 has a large capacity, installation work can be easily performed. Conversely, the capacity of the drainage tank can be increased without being limited by the operability of installation. Similarly, the drain trap 4d and the drain pipe 4e can also be increased in size without being restricted by the connection operability and piping operability. By adopting a suspension structure for suspending the drain 4 between a pair of floor beams 33, 33, and crossing from one end of the bathroom width direction W to the other, the depth of the drain 4 can be sufficiently increased, Width and length to ensure large capacity. In addition, according to the structure of the bathroom floor, the drainage pool 4 and the floor paving body 2 can be supported and connected to the common floor beam 33. Furthermore, the drainage pool 4 and the floor panel 5 can be connected via the floor beam 33 in a manner not directly interfering with each other. The floor beam 33 can improve the flexural strength by adopting a structure in which the upper and lower beam members 34 and 35 of the U-shaped cross section are fitted, and thus can reliably support the large-capacity drainage tank 4 and the large-area floor laying body 2 . By arranging a plurality of floor panels 5, the size of the floor paving body 2 can be adjusted corresponding to various sizes of the bathroom. By making the surface sheet 6 span the upper surfaces of the plurality of floor panels 5, the surface sheet 6 can cover the joint between the floor panels 5.
