Description

  TECHNICAL FIELD The present invention relates to a bathroom floor mounting structure and mounting method comprising a waterproof pan such as a unit bath, and more particularly to a bathroom floor mounting structure and mounting method considering level adjustment of a support bolt for supporting the floor structure and prevention of rattling. About.

  Waterproof pans that constitute bathroom floors such as unit baths are responsible for supporting all of the bathtubs installed inside, the hot water stored in them, the wall panels and doorways that separate the surroundings from the outside, the weight of the user, etc. However, it is made of FRP (Fiber Reinforced Plastic) in order to cope with complicated shapes and reduce its own weight, and the strength itself is not large.

  Further, the level adjustment of the waterproof pan is important in order to ensure the water gradient of the drainage and to prevent the deflection while the structure floor such as concrete where the waterproof pan is installed is uneven. Therefore, even though the unit bath (about 1280 mm × 1680 mm) of normal size is equipped with about 10 support legs, the support legs are provided with less support legs that support the waterproof pan, although the workability is better. The span between them is shortened to support strength and prevention of bending.

  Conventionally, as shown in FIG. 13, this support leg is inserted into a support leg 102 attached to a reinforcing rib 101 of a waterproof pan 100 by inserting a support bolt 103 with its head turned down, and moving it up and down. The level is adjusted by advancing and retreating, and by tightening the lock nut 104 to the support leg side, the support bolt is loosened or loosened by play of the thread of the female screw threaded on the support bolt and the support leg. The attachment structure and method which prevent are taken.

  However, when a waterproof pan is installed, the surrounding walls may already be built because the frame work precedes the equipment work. Even in the case of renovation, which has been increasing recently, it is often renovated with the existing walls remaining. In such a case, as shown in FIG. 13, there is no space for the worker to stand around the waterproof pan and work, and neither can he turn his hand to the back side of the waterproof pan. Even if it is not, the support leg provided in the center of the waterproof pan cannot be reached from the surroundings.

  In order to solve this problem, as shown in FIG. 14, a waterproof pan 140 supporting device having a wall panel mounting portion 142 on the periphery, which supports the waterproof pan 140, and an end portion of the wall panel is supported by the waterproof pan 140. A stand 146 disposed below the mounting portion 142 and a support bolt 150 screwed to the end portion of the stand 146 so as to be capable of screwing up and down and having an upper portion extending above the stand 146. And a waterproof pan support device provided in the wall panel mounting portion 142 and having a tool insertion hole 144 for turning the support bolt 150. The waterproof pan support device is disposed on the upper side of the gantry 146, and the support bolt is 150 inside. A cylindrical body 154 having a female screw portion 156 inserted through and screwed into the support bolt 150, and a tool for rotating the cylindrical body 154 provided on the upper portion of the cylindrical body 154 And a joint part 160 The cylindrical body 154 is screwed downwardly waterproof pan supporting device capable locks the support bolt 150 against the frame 146 has been proposed (e.g., see Patent Document 1.).

  According to this waterproof pan support device, a tool is inserted from the tool insertion hole 144 provided in the wall panel mounting portion 142 of the waterproof pan 140 and the cylindrical body 154 is rotated, and this cylindrical body 154 is attached to the upper surface of the gantry 146. The cylindrical body 154 has a support bolt 150 inserted into the cylindrical body 154 so that the supporting bolt 150 is inserted into the cylindrical body 154 and extends along the supporting bolt 150. It is supposed that the cylindrical body 154 can be rotated by simply engaging the tip of the tool for rotating the cylindrical body 154 with the engaging portion 160.

  However, this waterproof pan support device still has the following problems. The first is a problem similar to co-rotation. As shown in FIG. 14A, the support bolt 150 is temporarily placed at a high position so that the head does not reach the structure floor, and a minus driver is engaged with the slit 150a at the top of the support bolt 150 to support it. The bolt 150 is rotated to lower it. At this time, the cylindrical body 154 also rotates together with the support bolt 150 and descends. When the lower end of the cylindrical body 154 comes into contact with the gantry 146, the cylindrical body 154 cannot be lowered any more and stops rotating, but the support bolt 150 also stops rotating in conjunction with this. A phenomenon opposite to the so-called co-rotation generated by a nut or the like (hereinafter referred to as “co-stop”) may occur. In a normal working environment, the cylindrical body 154 can be fixed with a wrench or the like to prevent co-stopping, but it is not possible to look under the waterproof pan 140 or insert a wrench.

  For this reason, a person working on the waterproof pan 140 misunderstands that the head of the support bolt 150 has reached the structure floor, and this ends the level adjustment of the support bolt 150. Therefore, the span between the support bolts 150 reaching the structure floor 160 is lengthened, and the wrinkle is increased, which causes squeak noise and cracks.

  At this time, there is no problem if the length of the support bolt 150 and the cylindrical body 154 is sufficiently long and the level of the support bolt 150 is confirmed and then the cylindrical body 154 is gradually lowered. However, in this case, the wall panel placement portion 143 is at a high position, and the floor level itself is also high. This means that the ceiling height is lowered.

The second problem is, for example, the tool insertion hole 144 formed on the waterproof pan 140 on the support bolt 150 of the wall panel mounting portion 142. Recent wall panels have a thickness of around 20 mm because of the desire to secure as large a bathroom space as possible. Even if the insertion hole 144 for inserting the tool is provided there, it is necessary to make the hole as small as possible. Therefore, if a cylindrical body 154 larger than the diameter of the support bolt 150 is provided in order to avoid contact with the support bolt 150 as in the conventional example, an insertion hole 144 having a larger diameter is required. Furthermore, it is not practical to insert the cylindrical body 154 from the insertion hole 144 after the level of the support bolt 150 is adjusted because the diameter of the hole becomes larger.

  According to the bathroom floor mounting structure and the mounting method according to the present invention, the support bolt of the waterproof pan can be reliably grounded to the structural floor without locking together with the lock nut.

  According to the present invention, in the bathroom floor mounting operation, an insertion hole formed for inserting a tool can be made as small as possible.

  The present invention has the effect of reducing the height of the floor and reducing the level difference between the bathroom and the dressing room and ensuring a sufficient ceiling height.

  A first embodiment of a bathroom floor mounting structure according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a bottom view showing an overall outline of a waterproof pan 1 for a bathroom floor according to the present embodiment. Here, the waterproof pan 1 having a general size (about 1280 mm × 1680 mm) will be described as an example.

  The waterproof pan 1 is roughly divided into a bathtub mounting portion 2 in which a bathtub is disposed and a washing place 3. Then, the four rounds are raised, and a wall panel mounting portion 4 for mounting a wall panel and an entrance is formed. In addition, since the waterproof pan 1 is a thin member formed of FRP, reinforcing ribs 5 are arranged vertically and horizontally on the lower surface of the waterproof pan 1 to reinforce it.

  The support leg 6 of the waterproof pan 1 is placed in a place where a large load is applied. It is in the vicinity of the wall panel placing portion 4 where the wall panel is disposed, in the vicinity of the bathtub supporting leg 6 that supports the load of the bathtub and the hot water filled therein, and in the vicinity of the center of the washing place 3 where the person washes the body.

  About 10 support legs 6 of the waterproof pan 1 are provided in the waterproof pan 1 of such a size (in the example of this embodiment, 9 locations).

  Hereinafter, the bathroom floor mounting structure according to the present embodiment will be described with reference to the drawings. 2 is a longitudinal cross-sectional view of the mounting structure provided in the vicinity of the wall panel placement portion, and FIG. 3 shows a positional relationship of members constituting the mounting structure. It is a disassembled perspective view.

  As shown in FIG. 3, a cylindrical portion 15 having an inner diameter in which a lock nut 9 described later can be loosely fitted is provided at a portion where the orthogonal reinforcing ribs 5 and 5 intersect and the support leg 6 is attached. Further, the portion of the reinforcing rib 5 that contacts the cylindrical portion 15 bulges downward.

  The support leg 6 is formed of a substantially cylindrical main body 6a having substantially the same inner diameter as that of the reinforcing rib 15, and a U-shaped clip 6b protruding in four directions from the main body. And the clip 6b which apply | coated the adhesive agent to the inner surface is inserted in the lower end of the reinforcing rib 5 and 5 which cross | intersects, the lower end of the cylindrical part 15 and the main body 6a are contact | abutted, and it integrates with a waterproof pan. Since a lock nut 9 is inserted between the upper portion of the support leg 6 and the back surface of the waterproof pan 1, a certain distance is taken.

  Inside the main body 6a, a disc 6c is provided at a substantially central height, and this cylinder is divided up and down. In the center of the disk 6c, a bolt hole 6d having a size capable of inserting a support bolt 8 described later is formed.

  The upper part of the disk 6c abuts on the cylindrical portion 15 of the reinforcing rib 5, and its cross section is formed in a circular shape so that the lock nut 9 can rotate. On the other hand, the cross section of the lower part of the disk 6c is not circular but is formed in a hexagon, and the hexagon nut 7 is fitted in a non-rotatable manner. This may not be a hexagonal nut as long as the female screw is threaded, but may be formed integrally with the main body 6a.

  Since the head 8 a of the support bolt 8 is placed on the structural floor 99, the support bolt 8 is screwed into the hexagon nut 7 from the lower side of the support leg 6 with the head 8 a facing down.

  An engagement portion 8b for inserting a tool for rotating the support bolt 8 is provided at the end opposite to the head 8a of the support bolt 8, that is, the upper end. Specifically, it is a one-character groove for inserting a flathead screwdriver. The engagement portion may be a cross-shaped groove for inserting a Phillips screwdriver.

  In the upper part of the main body 6a, a lock nut 9 and a washer 10 are externally screwed onto the support bolt 8. The lock nut 9 is provided with an engaging portion 9a for inserting a tool for rotating the lock nut 9 at the upper end of a normal long nut. Specifically, it is a one-character groove for inserting a flathead screwdriver.

  The washer 10 functions as a wrench that holds the lock nut 9 in order to prevent the lock nut 9 from rotating when the level adjustment is performed by rotating the support bolt 8. Therefore, the surface in contact with the lock nut 9 and the disc 6c needs to have sufficient frictional resistance. In other words, it is sufficient if it has sufficient frictional resistance, but in the experiment, good results were obtained when a foamed elastic body was used.

  An insertion hole 11 for inserting a tool for rotating the support bolt 8 and the lock nut 9, for example, a flat-blade screwdriver from above the waterproof pan 1, is formed at the upper end of the wall panel placing portion 4. The diameter of the insertion hole 11 only needs to be large enough to allow a tool having a width engageable with the engaging portion 9a of the lock nut 9 to be inserted, and therefore can be made smaller than the diameter of the lock nut 9. . Since this insertion hole 11 can be made small in this way, after the floor structure is attached, when the wall panel is placed on the wall panel placement portion 4, it is completely hidden and visible to the user. No water leaks from 11. For this reason, since the lock nut 9 cannot be inserted from the insertion hole 11 after the waterproof pan 1 is installed at a predetermined position, it must be screwed into the support bolt 8 in advance as will be described later. Don't be.

  FIG. 4 shows a modification of the support leg 6. Unlike the embodiment described above, the reinforcing rib 5 in this modification does not bulge downward and is formed at the same height as the other portions. Accordingly, the upper part of the main body of the support leg 6 is lengthened to secure a space for housing the lock nut 9. Further, a triangular rib 17 is provided between the lower end of the clip 6b and a portion of the main body 6a located below the clip 6b for reinforcement.

  FIG. 5 is a cross-sectional view of the support leg 6 provided in the bathtub mounting portion 2 as viewed from the direction of arrows DD in FIG. As shown in the figure, the support leg 6 is basically different from that in the vicinity of the wall panel mounting portion 4 in that a waterproof cap 12 for hiding the insertion hole 11 is necessary because the wall panel is not mounted. However, other configurations are substantially the same. Also in this case, if the bathtub is placed, it will not be touched by human eyes, so it is only necessary to pay attention to waterproofness without worrying about the design.

  The bathroom floor mounting structure according to the present embodiment is configured as described above, and the mounting method will be described below with reference to the flowchart shown in FIG.

  When installing the bathroom floor structure, before placing the waterproof pan 1 at a predetermined position, the support bolts 8, the lock nuts 9 and the washers 10 are attached to the respective support legs 6, and the support legs 6 are adhered to the waterproof pan 1. It must be kept (step S10). However, this attachment work is usually performed at the factory before shipment.

  First, the support bolt 8 is inserted from the lower surface of the support leg 6, the washer 10 is inserted into the end of the support bolt 8 protruding from the upper surface of the support leg 6, and the lock nut 9 is screwed. In the conventional lock nut, the lower end of the lock nut needs to be separated from the disk at first so that the support bolt 8 does not stop together before landing on the building floor 99. Since it does not stop together with the support bolt 8, there is no problem even if the lower end of the lock nut 9 is lowered to the vicinity of the disc 6c. Therefore, the length of the lock nut 9 can be shortened, and as a result, the floor surface of the waterproof pan 1 The height of the gap with the support leg 6 can also be reduced, and the height of the floor can be reduced.

  Thus, when each member is attached to the support leg 6, an adhesive is applied to the clip 6 b of the support leg 6 to adhere the support leg 6 to a predetermined position of the waterproof pan 1. Thereby, the preparation work is completed.

  When the waterproof pan 1 is placed at a predetermined position at the installation site (step S20), level adjustment work is subsequently performed (step S30). FIG. 7 is a flowchart showing the flow of this level adjustment work.

  This level adjustment is performed from the support legs 6 arranged at the four corners, and the remaining support legs 6 are adjusted according to them. The level adjustment of these four corners is performed accurately using the level and water thread. At this time, if the support bolts 8 of the remaining support legs 6 are lowered too much, the waterproof pan 1 comes into contact with the structural floor before the support bolts 8 at the four corners, and the level of the waterproof pan 1 is not fixed. The support bolt 8 is assembled in a state where it is raised above a certain level, and the level adjustment of the support leg 6 is completed on the assumption that the support bolt 8 is lowered and the level is taken when it contacts the structural floor 99. .

  Therefore, first, a tool, in this embodiment, a flat-blade screwdriver is inserted from the insertion hole 11 drilled in the waterproof pan 1 (step S31), and the tool engagement portion 8b provided on the top of the support bolt 8, in this embodiment Engage with a single character groove (step S32). The minus driver used at this time must have a width smaller than the inner diameter of the lock nut 9 in order to rotate only the support bolt 8.

  Then, the minus driver is rotated to push down the support bolt 8 (step S33), and the level adjustment is completed when the head contacts the structure floor 99 (step S34). This operation is performed on all the support legs 6. As a result, it is possible to prevent problems such as the waterproof pan being bent more than necessary, causing a squealing and poor usability, or cracking.

  The movement of the lock nut 9 at this time will be described with reference to FIG. Originally, a slight gap is generated between the thread of the lock nut 9 and the thread of the support bolt 8 that are screwed together. As shown in FIG. 9A, before the lock nut 9 abuts against the washer 10, the thread bottom surface 9 b of the lock nut 9 is hooked on the thread top surface 8 d of the support bolt 8 by the weight of the lock nut 9. It is in the state. Therefore, when the support bolt 8 is rotated in the descending direction, the lock nut 9 also rotates together and descends.

  When the lock nut 9 is lowered to the height of the washer 10 and comes into contact, the weight of the lock nut 9 is supported by the washer 10 and released from the state of being hooked on the support bolt 8 as shown in FIG. The Contrary to the above, the lower thread surface 8e of the descending support bolt 8 comes into contact with the upper thread surface 9c of the lock nut 9 from which the lowering is prevented. At this time, if the washer 10 is not provided, the support bolt 8 is pushed up, and the fastening force in the opposite direction acts to make the rotation impossible. This is a joint stop.

  However, when the washer 10 having a large frictional force is interposed between the lock nut 9 and the disc 6c of the support leg 6, a frictional force larger than the fastening force is generated between the bottom surface of the locknut 9 and the washer 10. Occur. Since this frictional force breaks the fastening force between the screw thread lower surface 8e of the support bolt 8 and the screw thread upper surface 9c of the lock nut 9, the lock bolt 9 does not rotate, and the support bolt 8 continues to be screwed downward. It is possible to prevent the stoppage.

  In this case, the material of the washer 10 is not limited as long as it has a frictional force larger than the fastening force. However, for example, a material such as an elastic foam is pressed by the weight of the lock nut 9 and the surface sinks, so that it is possible to prevent the locking together more reliably.

  However, even if the level of the support bolt is adjusted in this way, if the level is left as it is, the support bolt 8 is loosened by vibration and the level is shifted, or there is play between the thread of the support bolt 8 and the internal thread, so that there is play. May occur. Therefore, the support bolt 8 is locked (step S40). FIG. 9 is a flowchart showing the flow of this locking operation.

  First, a tool, in this embodiment, a flathead screwdriver is inserted from the insertion hole 11 drilled in the waterproof pan 1 (step S41), and the tool engagement portion 9a provided on the top of the lock nut 9 is a single character in this embodiment. Engage with the groove (step S42).

  The width of the minus driver used at this time must be larger than the inner diameter of the lock nut 9. Therefore, the size of the insertion hole 11 is determined by the size of the minus driver used. However, the lock nut 9 is externally screwed onto the support bolt 8, and no gap is generated between the lock nut 9 and the support bolt 8.

  Then, the lock nut 9 is pushed down by rotating the minus driver (step S43). When the bottom surface of the lock nut 9 comes into contact with the disc 6c of the support leg 6 through the washer 10, and the rotation becomes impossible, the support bolt 8 Is completed (step S44). This operation is performed for all the lock nuts 9. As a result, it is possible to prevent the support bolt 8 from loosening due to vibration and shifting the level, or play in the thread between the support bolt 8 and the female screw, and thus rattling.

  Finally, where necessary, the insertion hole 11 is covered with a waterproof cap 12 to complete the installation of the bathroom floor.

  Next, 2nd Embodiment of the bathroom floor mounting structure which concerns on this invention is described with reference to FIG.10 and FIG.11. Here, the support legs 6 installed in the washing place 3 will be described as an example.

  Whereas in the first embodiment, a lock nut 9 that is externally fitted to the support bolt 8 is used, the bathroom floor mounting structure of the present embodiment is internally fitted to the support bolt 8 as shown in the figure. This is basically different in that a lock bolt 13 to be screwed is used, and other configurations are substantially the same as those of the first embodiment, and the same reference numerals are given and description thereof is omitted.

  The support bolt 8A has a hole of a predetermined length formed at the end facing the waterproof pan 1, and a female screw is threaded on the inner surface to form a screw hole 8c. At the bottom of the screw hole, there is provided an engaging portion 8b that can be engaged with a tool for applying turning force, and in the example in the present embodiment, a single-character groove for engaging a minus driver. The engaging portion 8b may be a cross-shaped groove for engaging a plus driver.

  The engaging portion 8b can be provided on the top of the support bolt 8 like the engaging portion 8b of the support bolt 8 in the first embodiment. However, from the viewpoint of making the insertion hole 11A as small as possible, it is desirable to provide it at the bottom.

  After the packing 14 for waterproofing is fitted, the lock bolt 13 passes through the insertion hole 11A formed in the waterproof pan 1 from above the waterproof pan 1 and is screwed into the screw hole 8c of the support bolt 8A. Combined. The packing 14 is sandwiched between the head of the lock bolt 13 and the portion of the insertion hole 11A that locks this head to prevent water used in the bathroom from leaking from the insertion hole 11A to the bottom of the waterproof pan 1. To do.

  Since the bathroom floor mounting structure according to the present embodiment is different from that according to the first embodiment as described above, the mounting method is naturally different. First, in the preparation stage for attaching each member to the waterproof pan 1, there is no lock nut 9 or washer 10 sealed in a closed space formed by the support leg 6 and the cylindrical portion 15 of the reinforcing rib 5. After the support bolt 8 is screwed to the support leg 6, the support leg 6 may be bonded to the reinforcing rib 5. Conversely, after the support leg 6 is bonded to the reinforcing rib 5, the support bolt 8 is fixed to the support leg 6. It can also be screwed together.

  In the level adjustment stage, the lock bolt 13 is not yet screwed to the support bolt 8. Therefore, there is no possibility that the support bolt 8 and the lock bolt 13 are locked together.

  At the stage of the locking operation, as shown in FIG. 12, first, the lock bolt 13 is inserted through the insertion hole 11A from the top of the waterproof pan 1 (step S51), and the tool is directly engaged with the lock bolt 13 (step S51). In step S52), the lock bolt 13 is rotated (step S53), and if it is confirmed that rotation is impossible (step S54), the locking operation is completed.

  According to this mounting structure, since the diameter of the lock bolt 13 is smaller than that of the support bolt 8A, the diameter of the insertion hole 11A drilled in the waterproof pan 1 can be further reduced. Is also advantageous.

  On the other hand, even if the diameter of the lock bolt 13 is small, since it is the support legs 6 and the support bolts 8A that receive the load, the same load as that according to the first embodiment can be supported. However, since the diameter of the lock bolt 13 is small, it may be inferior to the force for releasing the lock acting in the lateral direction. Therefore, the mounting structure of the first embodiment is used for the four corners where the resistance force in the lateral direction is required, and the bathtub mounting portion 2, and the mounting structure of the second embodiment is used for the washing place 3 and the central portion. It is also possible to properly use them.

  Locking the support bolt 8A with the lock bolt 13 causes the support bolt 8A to loosen due to vibration and shift in level, or there is play in the thread of the support bolt 8A and the female screw, resulting in rattling. Is prevented.

  The embodiments described above are for illustrative purposes and do not limit the scope of the invention. Accordingly, those skilled in the art can employ embodiments in which each or all of these elements are replaced by equivalents thereof, and these embodiments are also included in the scope of the present invention.
