Description

  The present invention relates to a wall corner joint structure, and more particularly, to a corner joiner structure for joining orthogonal wall panels to each other, for example, in a bathroom corner.

  Conventionally, in assembling bathroom units such as a unit bathroom and a system bathroom, as a method of joining orthogonal wall panels at a bathroom corner, as shown in FIG. The corner joiner 30 having a substantially C-shape in plan view is leaned on the outside of the section, and the M-shaped bent pieces 33 of both wall panels 1 and 2 are respectively inserted into the corner joiner 30 and applied to the locking portion 30a. A joint structure is known in which a joint joint 34 is press-fitted between the bent pieces 33 and 33 (see, for example, Patent Document 1).

  However, in this conventional example, the lower end of the corner joiner 30 is fixed in advance with a screw or the like. However, wobbling is likely to occur, and therefore, the folded piece 33 of the wall panels 1 and 2 while the operator supports the corner joiner 30. Is inserted into the corner joiner 30 and applied to the locking portion 30a, it is necessary to push in the joint joint 34, which makes it difficult to work alone. .

  Therefore, as another conventional example, for example, as shown in FIGS. 5A and 5B, a panel folding piece 36 of one wall panel 1 is overlapped with a fixing portion 35 of a corner joiner 31 that is substantially T-shaped in plan view, and a screw 37 And a joint structure in which the joint joint 34 is press-fitted into the gap 40 between the wall panels 1 and 2 with the panel folded piece 39 of the other wall panel 2 overlapped with the base 38 of the corner joiner 31. Proposed.

However, in this other conventional example, screw holes 41a and 41b are respectively provided in the fixed portion 35 of the corner joiner 31 and the panel folding piece 36 of the one wall panel 1 overlapping therewith, and the one wall panel 1 and the corner joiner 31 are provided. Needs to be fixed in advance with the screw 37, and the work of opening the screw holes 41a and 41b and the work of tightening the screw 37 are both time-consuming and increase the cost.

An object of the present invention is to provide a wall corner joint structure capable of improving the mounting strength of the cornering joiner to the wall panel and reducing the cost.

In order to solve the above problems, the present invention provides a wall corner joint structure including a cornering joiner 6 that joins wall panels 1 and 2 that are orthogonal to each other at a corner portion of a room. A panel extension piece 3 extending substantially parallel to the surface direction of the one wall panel 1 and a direction away from the other wall panel 2 from the tip of the panel extension piece 3 are folded back at the side end of the panel 1. A first panel folded piece 4 is provided, and a second panel folded piece 5 folded in a direction substantially parallel to the panel extending piece 3 is provided at a side end of the other wall panel 2, and the corner The upright joiner 6 has a base portion 7 disposed on a surface opposite to the surface of the second panel folding piece 5 on the panel extension piece 3 side, and protrudes from the base portion 7 in a substantially orthogonal direction. Flexibility to hold the 1-panel folded piece 4 A J-shaped hook portion 8 having a panel extending piece 3 from the base portion 7 and the L-shaped reinforcing piece 12 which extends in a direction substantially parallel is integrally formed, on the inner surface of the J-shaped hook portion 8 A projection 9 for clamping the first panel folding piece 4 is provided so as to project a gap interval A between the tip 8a of the J-shaped hook 8 and the base 7 facing the first panel. The corner joiner 6 is shorter than the protruding length B of the folded piece 4, and the corner joiner 6 is in a state where the distal end portion 8 a of the J-shaped hook portion 8 is in contact with the front surface 4 a of the first panel folded piece 4. By rotating the J-shaped hook portion 8 toward the rear surface 4b side of the first panel folding piece 4 with the 8a as a fulcrum, the first panel folding piece 4 can be put in a pinched state by elastic deformation of the J-shaped hook portion 8 in the expansion / contraction direction. In this clamping state, the base portion 7 is folded back to the second panel. 5 is configured to move to a surface opposite to the surface on the panel extension piece 3 side, and a second gap is formed in the gap 10 between the base portion 7 and the panel extension piece 3 of one wall panel 1. The panel folded piece 5 is inserted, and the joint joint 11 is press-fitted into the gap between the second panel folded piece 5 and the panel extension piece 3, so that the second panel folded piece 5 is joined to the joint joint 11 and the base. It is characterized by being comprised so that it can pinch | interpose with the part 7. FIG.

With such a configuration, the J-shaped hook portion 8 is rotated while holding the L-shaped reinforcing piece 12 and only the first panel folded piece 4 is clamped to hold the first panel folded piece 4 with a cornering joiner. it is possible to attach the 6 easily, as compared with the case of using the conventional kind of screws, unnecessary screwing work Do Rutotomoni, the rotation operation can be easily performed by pinching the L-shaped reinforcing piece 12 In addition, it is easy to work alone, and it is not necessary to make a screw hole in each of the wall panels 1 and 2 and the cornering joiner 6, so that workability is further improved. Further, since the projection 9 of the J-shaped hook portion 8 is clamped by the first panel folded piece 4, the J-shaped hook portion 8 can be reliably secured in a state where the first panel folded piece 4 does not rattle. The second panel folded piece 5 is sandwiched between the joint joint 11 and the base portion 7 so that it can be prevented from coming off, and the gap between the base portion 7 and the second panel folded piece 5 can be prevented. It is possible to prevent the occurrence of rattling.

  The present invention adopts a system in which the J-shaped hook portion of the corner joiner is rotated to hold the first panel folded piece of one wall panel, so that the screw can be compared with the case where a conventional screw is used. Stopping work is not required and one person's work becomes easy, and the workability is greatly improved. Further, since it is not necessary to drill screw holes in the wall panel and the cornering joiner, workability is further improved. It is also effective for cost reduction. Further, the protrusion of the J-shaped hook portion can prevent the rattling from occurring at the fitting portion with the first panel folding piece, and the rattling between the base portion and the second panel folding piece by the joint joint. Therefore, it is possible to improve the mounting strength of the cornering joiner with respect to the orthogonal wall panel while having a structure that does not require screwing.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The cornering joiner 6 of the present embodiment is used to join the wall panels 1 and 2 that are orthogonal to each other at the bathroom corner when assembling a bathroom unit such as a unit bathroom or a system bathroom.

  As shown in FIG. 1, a panel extending piece 3 extending substantially parallel to the surface direction of the one wall panel 1, and a panel extending piece 3, A first panel folded piece 4 is provided which is folded in a direction away from the other wall panel 2 from the tip. Further, a second panel folded piece 5 folded in a direction substantially parallel to the panel extending piece 3 is provided at a side end portion of the other orthogonal wall panel 2.

  In the cornering joiner 6 according to the present embodiment, the base portion 7, the J-shaped hook portion 8, and the L-shaped reinforcing piece 12 are formed as an integrally molded product of synthetic resin.

  The base portion 7 is arranged behind the second panel folded piece 5, that is, on the surface opposite to the surface on the panel extension piece 3 side. The second panel folded piece 5 can be sandwiched between the first panel 11 and the second panel. Here, the front end portion 7a of the base portion 7 has a thick shape, and the gap 10 between the panel extending piece 3 and the second panel folded piece 5 is narrowed, and the strength of the base portion 7 is improved.

  A J-shaped hook portion 8 projects from the rear end portion of the base portion 7 in a substantially orthogonal direction. The J-shaped hook portion 8 has an inverted J-shaped cross section capable of sandwiching the first panel folded piece 4, and is open facing the base portion 7. One or a plurality (two in this example) of protrusions 9 project from the inner surface of the J-shaped hook 8 on the tip 8a side. The protruding portion 9 rattles the J-shaped hook portion 8 with respect to the first panel folded piece 4 by clamping the first panel folded piece 4 when the first panel folded piece 4 is clamped by the J-shaped hook portion 8. It works to prevent it from coming off in a state that does not cause any problems.

  Further, the gap interval A between the tip 8 a of the J-shaped hook portion 8 and the base portion 7 facing the J-shaped hook portion 8 is shorter than the protruding length B of the first panel folded piece 4.

  The cornering joiner 6 having the above-described configuration has the J-shaped hook portion 8 as the first fulcrum with the distal end portion 8a serving as a fulcrum in a state where the distal end portion 8a of the J-shaped hook portion 8 is in contact with the front base portion 4a of the first panel folding piece 4. By rotating the panel folding piece 4 toward the rear surface 4b, the first panel folding piece 4 can be held in a compressed state by the elastic deformation of the J-shaped hook portion 8 in the expansion / contraction direction. The panel folding piece 5 is configured to move to a surface opposite to the surface on the panel extension piece 3 side.

  A joint joint 11 is press-fitted between the panel extension piece 3 and the second panel folded piece 5. The joint joint 11 is made of, for example, a resin-extruded product such as ABS or PS, and a wide head portion 11a and a shaft portion 11c having fin-shaped crimping pieces 11b protruding from both sides are integrally formed. The joint joint 11 functions to sandwich the second panel folded piece 5 between the joint joint 11 and the base portion 7 and to seal the joint between the orthogonal wall panels 1 and 2. .

  Next, an example of a joining operation using the cornering joiner 6 having the above configuration will be described with reference to FIG. A cornering joiner 6 is attached to one of the first panel folding pieces 4 in advance. First, as shown by the phantom line in FIG. 3, with the front end portion 8a of the J-shaped hook portion 8 in contact with the front base portion 4a of the first panel folding piece 4, the front end portion 8a of the J-shaped hook portion 8 is used as a fulcrum. The cornering joiner 6 is rotated. At this time, the L-shaped reinforcing piece 12 can be pinched to easily perform the rotation operation. Note that the cornering joiner 6 may be fixed and the one wall panel 1 may be rotated as shown in FIGS. At this time, by rotating the J-shaped hook portion 8, the first panel folding piece 4 is expanded by elastic deformation and then reduced to the original state by the self-restoring force, that is, by elastic deformation in the expansion / contraction direction. It will be in the state clamped in the shape hook part 8 (FIG.2 (c), the state shown as the continuous line of FIG. 3). At this time, as shown in FIG. 1, the protrusion 9 provided in the J-shaped hook portion 8 presses the first panel folded piece 4, so that the J-shaped hook portion 8 is pressed against the first panel folded piece 4. In addition to being in a state of being reliably prevented from being loose, a gap 10 is formed between the base portion 7 of the cornering joiner 6 and the panel extension piece 3. Thereafter, the second panel folded piece 5 of the other wall panel 2 is inserted into the gap 10 as shown in FIG. As a result, the base portion 7 is disposed behind the second panel folded piece 5, and finally, as shown in FIGS. 2 (e) and 2 (f), the panel extension piece 3 and the second panel folded piece 5. The joint joint 11 is press-fitted into the gap from the inside of the bathroom. As a result, the second panel folded piece 5 is sandwiched between the joint joint 11 and the base portion 7, and the joining operation of the wall panels 1 and 2 by the cornering joiner 6 is completed (the state of FIG. 1). ).

  Therefore, when attaching the J-shaped hook portion 8 of the cornering joiner 6 to the first panel folded piece 4 having the above-described configuration, a method of rotating the J-shaped hook portion 8 to sandwich the first panel folded piece 4 is adopted. By doing so, the cornering joiner 6 can be easily attached to the one wall panel 1 with one touch. Therefore, without using a conventional screw, screwing work is not necessary, and one person's work is facilitated, and workability is greatly improved. In addition, since it is not necessary to make screw holes in the wall panels 1 and 2 and the cornering joiner 6, workability is further improved and cost reduction is effective.

  Further, since the J-shaped hook portion 8 and the base portion 7 are orthogonal to each other in an L shape in plan view, the forward and backward movement of the cornering joiner 6 is a sandwiched portion between the J-shaped hook portion 8 and the first panel folding piece 4. And the horizontal movement of the cornering joiner 6 is blocked by the locking portion between the base portion 7 and the second panel folding piece 5. Further, since the protrusion 9 of the J-shaped hook portion 8 is clamped by the first panel folded piece 4, rattling occurs at the fitting portion between the J-shaped hook portion 8 and the first panel folded piece 4. Can be prevented. Furthermore, since the second panel folded piece 5 is sandwiched between the joint joint 11 and the base part 7, the occurrence of rattling between the base part 7 and the second panel folded piece 5 can be prevented. Accordingly, it is possible to improve the strength of attaching the cornering joiner 6 to the orthogonal wall panels 1 and 2 while having a structure that does not require screwing.

  In addition, since the J-shaped hook portion 8 is rotated and fitted to the first panel folding piece 4, the gap 10 between the panel extension piece 3 and the second panel folding piece 5 is set to the first panel folding piece 4. Even when it is narrower than the protruding length B, the J-shaped hook portion 8 can be attached to the first panel folded piece 4. Accordingly, since the gap 10 can be narrowed, waterproof sealing with the joint joint 11 can be easily performed.

  Further, in the process of rotating the J-shaped hook portion 8 and sandwiching the first panel folded piece 4, the J-shaped hook portion 8 can be sufficiently bent in the expanding direction. There is also an advantage that it is possible to easily cope with different types of B.
