Description

  The present invention relates to an interior structure and an interior structure member capable of preventing the makeup sheet attached to the base board from being twisted or peeled off due to vibration caused by an earthquake or the like.

For example, as an interior structure in which adjacent baseboards are arranged so as to be orthogonal to each other, a gap is formed between the baseboards to prevent the baseboards from wavy or cracking due to vibration caused by an earthquake or the like. A structure in which joints are provided between them by fixing them to the housing is adopted. In such a structure, the interior structural member is fixed to one baseboard side so as to cover the joint casing in a state where the change in the gap between the baseboards is allowed. As the interior structural member, a member having a hollow flexible deformable portion that extends toward the other base board and contacts the base board is disclosed. (See Patent Document 1).
JP-A-9-228606

  In the structure in which the baseboards arranged so as to be orthogonal to each other as described above are fixed to the housing with a gap between them, a part of the cosmetic sheet attached to the surface of both baseboards is caught in the joint To be stored. That is, a part of the decorative sheet is sandwiched between the deformed portion of the interior structural member provided on one base board and the other base board with which the deformed portion abuts. As described above, when a decorative sheet is sandwiched between the base board and the interior structural member, air movement between the base board and the interior structural member occurs when air moves due to fine movement of the casing. Ventilation is performed through the protective sheet, and as a result, suspended matters in the atmosphere may adhere to the decorative sheet, and the white decorative sheet may turn black. At the same time, there are problems such as twisting and peeling of the cosmetic sheet.

  The present invention has been made in consideration of such circumstances, and can prevent deformation that occurs in the base board when a vibration force is applied due to an earthquake or the like, and has good makeup that is free from twisting and peeling. It is providing the interior structure and interior structure member which can maintain the sheet | seat for interior.

  Accordingly, in order to achieve the above object in the present invention, first, the invention according to claim 1 is arranged such that a plurality of base boards are arranged in a casing with gaps between the base boards, and the gaps between the base boards are arranged. In an interior structure in which an interior structural member that covers the casing of the joint between these base boards is fixed to the base board in a state where change is allowed, the interior structure member is located on the other adjacent side of one base board. A fixed portion fixed to the surface, and an elastically deformable deformable portion extending from the fixed portion toward the other base board and contacting the other base board. A first plate portion extending from the end portion of the fixed portion toward the housing, and a second plate portion extending from the front end side of the first plate portion to the other base board side, Surface of the base board Terminal portion of the decorative sheet to be attached, characterized in that it is housed in the interior side of the flexible portion.

  The invention according to claim 2 is used for an interior structure in which a plurality of base boards are fixed to the housing with a gap between the base boards, and a joint is provided between them. Is an interior structural member that covers the casing of the joint in a state that permits the use of the joint, and a decorative sheet is pasted together with the base board, and is fixed to the surface on the other side of the base board And an elastically deformable deformable portion that extends from the fixed portion toward the other base board and contacts the other base board, and the deformable portion extends from the end of the fixed portion. The first plate portion extending to the housing side and the second plate portion extending from the front end side of the first plate portion to the other base board side are configured.

  According to the first aspect of the present invention, by providing the interior structural member between the baseboards, it is possible to follow the change in the gap between the baseboards due to the fine movement of the casing, and the terminal portion of the decorative sheet is provided in the interior Since the ventilation of the cosmetic sheet is blocked by being housed inside the deformed part without being sandwiched between the structural member and the base board, blackening of the cosmetic sheet due to air movement is prevented. In addition, it is possible to maintain a good adhesion state of the cosmetic sheet in the gap line, and it is possible to eliminate gaps at the joints. Furthermore, since the cosmetic sheet follows the elastic deformation of the deforming portion, it is possible to prevent the cosmetic sheet from being twisted or lifted off due to a fine movement of the casing. In addition, the deformed portion does not contact the cosmetic sheet attached to the base board, but contacts the portion of the base board where the cosmetic sheet is not attached. There is no end. Therefore, it is possible to maintain the state of sticking of the cosmetic sheet having a good appearance. Such an effect is achieved even when the baseboards move in parallel due to lateral or vertical deflection of the housing, and are applied to the decorative sheet attached to the baseboard on the interior structure member mounting side and the other baseboard. Since the dressed cosmetic sheet is separated at the deformed portion, no twist occurs. This is a state in which the terminal portion of the decorative sheet adhered to the other base board on the interior structure member mounting side is adhered to the surface of the second plate portion of the interior structure member. Has lower adhesive strength than the part pasted on the surface of the baseboard, and in particular, the adhesive for applying the decorative sheet has poor adhesion to the surface of the synthetic resin. Since it does not affect the entire cosmetic sheet by peeling off at the time, it is presumed that it acts to prevent the occurrence of twisting.

  According to invention of Claim 2, by providing a deformation | transformation part between foundation | substrate boards, it can track the change of the clearance gap between foundation | substrate boards by the fine movement of a housing. Moreover, since the terminal part of the decorative sheet can be housed inside the deformation part, the ventilation of the decorative sheet can be blocked. Thereby, the blackening of the cosmetic sheet accompanying ventilation can be prevented, the state of sticking of the cosmetic sheet in the gap line can be kept good, and the gaps at the joints can be eliminated. Furthermore, since the cosmetic sheet follows the elastic deformation of the deforming portion, the cosmetic sheet can be prevented from being twisted or lifted off due to a fine movement of the casing. In addition, the deformed portion is not brought into contact with the cosmetic sheet attached to the base board, but is brought into contact with a portion of the base board where the cosmetic sheet is not attached, resulting in a twist in the cosmetic sheet. There is no end. Therefore, it is possible to maintain the state of sticking of the cosmetic sheet having a good appearance. Such an effect is achieved even when the baseboards move in parallel due to lateral or vertical deflection of the housing, and are applied to the decorative sheet attached to the baseboard on the interior structure member mounting side and the other baseboard. Generation | occurrence | production of a twist can be prevented by providing so that the worn cosmetic sheet may isolate | separate in a deformation | transformation part. This is a state in which the terminal portion of the decorative sheet adhered to the other base board on the interior structure member mounting side is adhered to the surface of the second plate portion of the interior structure member, Adhesive strength is weaker than the part pasted on the surface of the baseboard, especially because the adhesive for applying the decorative sheet has poor adhesion to the surface of the synthetic resin, the baseboards were subjected to vibration in the parallel direction. Since it does not affect the entire cosmetic sheet by peeling off at the time, it is presumed that it acts to prevent the occurrence of twisting.

Next, a first embodiment of the present invention will be described below with reference to FIGS.
FIG. 1 shows an example in which the interior structure of the first embodiment is applied to a wall structure. The front side (indoor side) is a flat surface portion 2a and a flat surface portion 2b perpendicular to the surface portion 2a. The housing 2 made of concrete forming the corner 6 and the pair of adjacent base boards 4 and 5 of the same thickness fixed to the surface portions 2a and 2b of the housing 2, and the base boards 4 on the surface portions 2a and 2b. , 5 and adhesives 30 and 31 for fixing. The base boards 4 and 5 may be screws fixed to the base constituent material.

  The two base boards 4 and 5 are arranged substantially orthogonally by being fixed to the respective surface portions 2a and 2b of the housing 2, and in this state, the surface on the indoor side of one base board 4 A side surface (opposite surface) 4a orthogonal to 4b and the interior side surface (opposite surface) 5b of the other base board 5 are spaced apart from each other in parallel, and the side surface 4a and the surface 5b are spaced apart from each other. A gap, that is, a board joint W is formed between the two.

  The board joint W is provided with a synthetic resin gap allowing member (interior structure member) 1 that covers the housing 2 in a state in which the change in the board joint W, that is, the gap between the adjacent base boards 4 and 5 is allowed. It has been. This gap-allowing member 1 is fixed to one base board 4, and has a rectangular fixed part 10 having a predetermined thickness and a direction from one end in the width direction of the fixed part 10 to the other base board 5. The fixed portion 10 and the deformable portion 11 are integrally formed by extrusion molding.

  As shown in FIG. 2, the fixing part 10 has a concavity and convexity 45 continuous on the surface and is formed so that one end side in the width direction becomes thinner toward the tip side. In addition, as shown in FIG. 3, a number of rhombus-shaped through holes 12 are aligned in the center in the width direction in one row along the longitudinal direction, and a number of through holes 13 are provided in an aligned state on each side. is doing.

As shown in FIG. 1, the deforming portion 11 provided so as to extend from one end portion in the width direction of the fixing portion 10 to the other base board 5 side is arranged from the end portion of the fixing portion 10 to the fixing portion 10. A flat plate-like first plate portion 16 extending along the side surface 4a toward the housing 2 side perpendicular to the housing 2 and extending toward the other base board 5 side while being folded back from the front end side of the first plate portion 16 The flat plate-like second plate portion 17 is formed into a substantially V-shaped cross-sectional view, and the second plate portion 17 is folded at a predetermined angle θ ₁ with respect to the first plate portion 16. That is, as shown in FIG. 2, the angle between the surface 17b of the surface 16b and the second plate portion 17 of the first plate portion 16 is in the angle theta _1. In addition, the plate | board thickness of the 2nd board part 17 of the deformation | transformation part 11 is formed thinly as it goes to a front-end | tip.

Such a deforming portion 11 is formed by the first plate portion 16 and the second plate portion 17 in accordance with the contact and separation between the ends opposite to the boundary end portions of the first plate portion 16 and the second plate portion 17. by the angle theta ₁ is varied from time to time Nasu, the one having an elastic stretchability in its extending direction. The deformation | transformation part 11 follows the change of a clearance gap by carrying out the expansion-contraction deformation | transformation in the mutual contact / separation direction of the base boards 4 and 5 from the elasticity. This also ensures that the deformed portion 11 is in contact with the base board 5 and always covers the housing 2 in the gap between the base boards 4 and 5. The surface of the fixed portion 10 is provided with a protrusion 19 (see FIG. 2) that protrudes outward from the end on the first plate portion 16 side so as to follow the unevenness 45 formed on the surface. Thereby, the connection part of the fixing | fixed part 10 and the 1st board part 16 is strengthened.

  The clearance allowing member 1 is provided between the base boards 4 and 5 such that the tip of the second plate portion 17 of the deformable portion 11 is brought into contact with the base board 5, and the fixing portion 10 is the base board. 4 is fixed to the surface 4b of 4 with an adhesive putty or the like.

As described above, the base putty 20 is applied from the fixing portion 10 of the gap allowing member 1 fixed to the base board 4 to the surface 4b of the base board 4 to smooth the front side. Then, a decorative sheet 22 is affixed to the base putty 20 and the surface 4b side of the base board 4, and the base putty 20 is applied to the fixing portion 10 of the gap allowing member 1 at the terminal side. Is attached to the first plate portion 16. Further, a similar decorative sheet 23 is also attached to the surface 5 b of the base board 5, and the terminal portion of the decorative sheet 23 is attached to the second plate part 17 of the gap allowing member 1. As a result, the end portions on the side close to each other of the decorative sheets 22 and 23 are housed together on the indoor surface of the deformable portion 11. The decorative sheets 22 and 23 are attached to the surface of the base board 4 using an adhesive, cut in anticipation of the dimensions of the terminal portions of these decorative sheets being wound around the deformable portion 11, and each terminal portion is used with a spatula or the like. Then, it is pushed into the deformation part 11 and stored. In addition, due to the property that the adhesive for sticking the decorative sheet can be re-applied, it is also possible to place each terminal part in the deformed part 11 after temporarily attaching the decorative sheets 22 and 23 and adjusting the appearance. .
Thus, by accommodating the terminal portion on the surface (inside the room) of the deformable portion 11, ventilation to the housing 2 side through the decorative sheets 22 and 23 is blocked. Further, by forming the tip of the second plate portion 17 thin, the spatula will not hit when the terminal portions of the decorative sheets 22 and 23 are inserted.

  Next, the construction of the above interior structure will be described. Adhesives 30 and 31 are applied to appropriate positions of the surface portions 2 a and 2 b of the housing 2, and the side surface 4 a of the base board 4 is brought into contact with the surface 5 b of the base board 5. Then, a gap is provided between the surface 5b of the base board 5 and the side surface 4a of the base board 4 so that the deformable portion 11 of the gap permitting member 1 can be inserted. Press against 30 and 31 to fix.

  The gap between the surface 5b of the base board 5 and the side surface 4a of the base board 4 can form a gap along the deformed portion 11 by attaching the gap allowing member 1 to the base board 4 and using it as a ruler. Thereby, a board joint W is formed between the surface 5 b of the base board 5 and the side surface 4 a of the base board 4. The fixing portion 10 is bonded to the base board 4 with the deformable portion 11 being inserted into the board joint W.

  Further, in a state where the gap allowing member 1 is fixed to the base board 4, the base putty 20 is applied from the fixing portion 10 to the surface 4 b of the base board 4 as shown in FIG. Then, as shown in the figure, a cosmetic sheet 22 is pasted on the surface 4b of the base board 4 and the surface of the base putty 20, and a cosmetic sheet 23 is pasted on the surface 5b of the base board 5, respectively. , 23 are accommodated on the surface (indoor side) of the deformable portion 11.

According to the interior structure and the gap allowance member 1 described above, even when a vibration force due to an earthquake or the like is applied, the gap allowance member 1 is provided between the base boards 4 and 5 so that the base board due to the fine movement of the housing 2 can be provided. It is possible to follow the change in the gap between the four and five. That is, as the angle θ ₁ formed by the first plate portion 16 and the second plate portion 17 changes as necessary with fine movement, the change in the gap between the base boards 4 and 5 can be followed, and fine movement can be absorbed without opening a gap. Will do. Further, the absorption of the fine movement is possible not only by the fluctuation of the angle θ ₁ but also by the rotation of the deformable part 11 with respect to the fixed part 10. That is, since the fixed portion 10 is the same elastically deformable material as the deformable portion 11, it can be deformed in accordance with the movement of the deformable portion 11. Therefore, since the deformation | transformation part 11 rotates centering on a boundary part with respect to the fixing | fixed part 10, it can follow the change of the clearance gap between the side surface 5a of the base board 5 and the surface part 2a of the housing 2 by fine movement. Absorption of fine movement is possible.

  Further, by adhering the decorative sheets 22 and 23 to the surfaces 16b and 17b of the first plate portion 16 and the second plate portion 17 without being sandwiched between the gap allowing member 1 and the base boards 4 and 5, The ventilation of the decorative sheets 22 and 23 is blocked, and blackening of the decorative sheets 22 and 23 due to the movement of air can be prevented.

  And as above-mentioned, also when sticking the decorative sheets 22 and 23 to each foundation | substrate board 4 and 5, respectively, each terminal part of each decorative sheet 22 and 23 is made into the surface (indoor side) of the deformation | transformation part 11. FIG. By adhering to, the joint portions of the cosmetic sheets 22 and 23 can be made inconspicuous from the outside, so that the adhesive state of the cosmetic sheets 22 and 23 in the gap line can be kept well and the joints It is possible to eliminate gaps in the part.

  Furthermore, since the decorative sheets 22 and 23 follow the deformation of the deformable portion 11, the decorative sheets 22 and 23 can be prevented from being twisted or lifted off due to the fine movement of the housing 2. Therefore, it becomes possible to maintain the sticking state of the cosmetic sheets 22 and 23 having a good appearance.

  Moreover, the deformation | transformation part 11 will contact | abut to the part to which the decorative sheet 23 of the base board 5 is not affixed rather than contact | abutting to the decorative sheet 23 affixed on the base board 5, and the cosmetic sheet 23 There will never be a twist.

  Further, since the surface area on which the cosmetic sheet 22 is adhered is increased by the continuous unevenness 45 provided on the surface of the fixed portion 10, the adhesiveness is improved, and displacement of the cosmetic sheet 22 due to fine movement can be prevented. A reliable and good application of the cosmetic sheet 22 is enabled.

  Such an effect is obtained even when the base boards 4 and 5 move in parallel due to lateral or vertical deviation of the housing 2, and the decorative sheet 22 attached to the base board 4 on the attachment side of the clearance allowing member 1. Since the decorative sheet 23 adhered to the other base board 5 is separated by the deformable portion 11, no twist occurs. This means that the terminal portion of the decorative sheet 22 attached to the other base board 4 on the attachment side of the gap allowing member 1 is bonded to the surface 17b of the second plate portion 17 of the gap allowing member 1. This part has a lower adhesive strength than the part pasted on the surface 4b of the base board 4, and in particular, the adhesive for applying the decorative sheet has a poor adhesive property to the surface of the synthetic resin. , 5 are peeled off when vibrations are applied in the parallel direction, so that the whole of the decorative sheets 22 and 23 is not affected.

Next, a second embodiment of the present invention will be described below mainly with reference to FIG.
FIG. 4 shows a clearance allowing member (interior structure member) 33 according to the second embodiment adapted to the interior structure. The deformable portion 34 of the clearance allowing member 33 includes a first plate portion 35 extending from the end portion of the fixing portion 10 to the housing 2 side while extending toward the other base board 5 side, and the first plate portion 35. And a second plate portion 36 that extends from the leading end side to the other base board 5 side. The tip of the second plate portion 36 is thin and is in a state along the surface 5 b of the other base board 5. Then, the second plate portion 36 is folded back at a predetermined angle θ ₂ so as to be wider than the angle θ _{1 with} respect to the first plate portion 35, and therefore the surface 35 b of the first plate portion 35 and the second plate portion. angle between the surface 36b of the 36 is in the theta _2.

According to the second embodiment described above, since the first plate portion 35 is inclined with respect to the fixed portion 10, the deformable portion 34 further extends toward the base board 5 side. Thus, the gap between the base boards 4 and 5 can be allowed to be larger. In addition, since the angle θ ₂ formed by the surface 35b of the first plate portion 35 and the surface 36b of the second plate portion 36 becomes a wide angle, the variation range of the angle θ ₂ is expanded and the first plate that can be contacted and separated is provided. Since the distance in the contact / separation direction between the end portion of the portion 35 and the end portion of the second plate portion 36 becomes long, when a vibration force due to an earthquake or the like is applied, the gap between the base boards 4 and 5 due to fine movement, It is possible to follow a greater change and increase the absorption power of fine movement. Further, fine movement can be absorbed not only by the change of the angle θ ₂ but also by the rotation of the deformable portion 34 with respect to the fixed portion 10. That is, the deformation portion 34 can be deformed in accordance with the movement of the deformation portion 11 by the fixing portion 10 that can be elastically deformed. Therefore, the deformable portion 34 can follow the change in the gap between the side surface 5a of the base board 5 and the surface portion 2a of the housing 2 due to the fine movement by rotating around the boundary portion with respect to the fixed portion 10. Absorption of fine movement is possible.

Next, a third embodiment of the present invention will be described below mainly with reference to FIG.
The present embodiment is an interior structure that enables the use of the gap-allowing members 1 and 33. The difference from the interior structure of the first embodiment is that adjacent base boards 4 and 5 are arranged on substantially the same plane. It is a point that has been. Here, the case where the clearance tolerance member 1 is used will be described.
Both the base boards 4 and 5 have an adhesive 30 on the surface portion 2a of the housing 2 in a state in which a gap in which the deformable portion 11 of the clearance allowing member 1 can be inserted and the opposing side surfaces 4a and 5a are arranged in parallel with each other. In this way, they are arranged in substantially the same plane and form a gap, that is, a board joint W, between the side surfaces 4a and 5a. By providing the gap allowing member 1 on the board joint W, the casing 2 in the gap between the base boards 4 and 5 is always covered. However, since the base boards 4 and 5 are arranged on the same plane, if the gap allowing member 1 is provided on one base board 4, a step is generated on the surface 5 b of the other base board 5. Therefore, in order to make the surface heights of the base boards 4 and 5, only the fixing portion 10 obtained by cutting the deformable portion 11 of the gap allowing member 1 is provided on the surface 5 b of the other base board 5, or the thickness equivalent to the fixing portion 10. Or a plate portion having As shown in the figure, the second plate portion 17 of the deformable portion 11 may be cut out. Then, by applying the base putty 20 from above and smoothing the front side and pasting the cosmetic sheet 23, it can be made substantially flush with the cosmetic sheet 22 stuck on the base board 4. .
Therefore, also in this embodiment, the same effect as the above-mentioned embodiment can be produced.

  As described above, even when a vibration force is applied to the housing 2 due to an earthquake or the like, it is possible to prevent the deformation of the base boards 4 and 5, and a good cosmetic sheet 22 that is free from twisting and peeling, 23 sticking can be maintained.

 In the above description, the wall structure is described as an example of the interior structure. However, the present invention can also be applied to a ceiling structure and can be used for a boundary portion between a wall and a ceiling. Further, as the base boards 4 and 5, various boards such as a plaster board, a veneer plywood, and a calcium board can be applied. In the first embodiment, the interior structure having a substantially right-angled corner has been described. However, the present invention is not limited to this. For example, the clearance-allowing members 1 and 33 can be applied to a ship bottom ceiling having an angle of 135 degrees. Is possible. Further, the gap allowing member 1 may be an integrally molded product by extrusion using a plurality of materials as necessary.
