Description

  The present invention relates to a structure in which a long wall panel is installed between adjacent studs.

  2. Description of the Related Art Conventionally, a structure in which a long panel having a sound function capable of setting a living room to be in a desired acoustic state is fitted and installed in a part of the wall of the living room is known (see, for example, Patent Document 1). .

  When fixing this type of long panel to the wall surface by screwing over its entire length, it takes time to attach and detach the long panel and the screws are exposed on the surface of the long panel. And design properties are impaired. Therefore, even when a cover material that covers the screw head is used, there is a problem that the design property is lowered as compared with the case where the screw is not fixed.

  Although it is conceivable to screw only the both ends of the long panel in the longitudinal direction, in this case, the central portion that is not fixed to the wall surface of the long panel is bent or the wall surface is deformed due to deformation of the wall itself. It is not preferable as a method for fixing the long panel, such as a situation where it does not adhere to the long panel. Note that the method of adhering the long panel to the wall surface has a problem that it cannot be removed for maintenance.

See JP-A-6-158750

  The present invention has been made in view of the above-described conventional problems, and the object of the present invention is to make it easier to attach and detach a long wall panel as compared with conventional screwing or the like, and to improve workability and maintenance. It is intended to provide an installation structure of a wall panel that can improve the appearance design by suppressing the forward projecting dimension of the wall panel with respect to the studs.

  In order to solve the above-mentioned problems, the present invention is a structure in which a long wall panel 4 is installed between adjacent studs 2, and the long wall panel 4 is spaced from the adjacent studs 2. A wider surface material 4c, and a rear surface bulging portion 4a that bulges rearward B from the center side in the lateral width direction G of the rear surface of the surface material 4c and is housed in the space 3 between the studs 2. The locking tool 5 is fixed to the back side of the wall panel 4, and the locked tool 6 to which the locking tool 5 is hooked and locked from the front N is fixed to the side surface 2 a side of the stud 2. With the rear bulge 4a of the wall panel 4 arranged in the space 3 and the both ends 4b of the surface material 4c in the lateral width direction G arranged in front N of the intermediate pillar 2, the locking tool 5 is moved forward N The whole wall panel 4 is fixed to the stud 2 while being pulled toward the rear B of the space portion 3 by being hooked on the locked tool 6 from above.

  By adopting such a configuration, the locking tool 5 on the back side of the wall panel 4 is moved from the front N while the back bulging portion 4a of the long wall panel 4 is placed in the space 3 between the studs 2. The wall panel 4 can be easily fixed to the studs 2 simply by hooking the hooks 6 on the side faces 2a of the studs 2 respectively. At this time, since the entire wall panel 4 is locked so as to be drawn toward the rear B of the space portion 3, it is possible to suppress the protrusion dimension of the surface material 4 c of the wall panel 4 to the front pillar 2 toward the front N to be small. become able to.

  In the present invention, the locking member 5 is formed in a bowl shape protruding rearward B from the back surface 13a of the wall panel 4, and the locked member 6 protrudes to the side J of the side surface 2a of the intermediate post 2. In a state where the hook-shaped locking tool 5 is hooked on the vertical plate-shaped locked tool 6 from the front N, the hook-shaped locking tool 5 pulls the wall panel 4 to the rear B so as to be vertical. It is preferable to press against the back surface 13 a of the plate-like locked tool 6.

  In this case, using the space portion 3 on the side J of the side surface 2a of the intermediary pillar 2, the locked device 6 and the locking device 5 can be hooked and locked with good appearance at a position that cannot be seen from the indoor side. In addition, since the wall panel 4 is pulled and fixed to the rear B by pressing the hook-shaped locking tool 5 against the back surface 13a of the vertical plate-shaped locked tool 6, the surface material 4c of the wall panel 4 is fixed. Can be arranged as close as possible to the front side of the stud 2.

  In the present invention, it is preferable that the hooking surface of the locking tool 5 to the locked tool 6 is formed by the inclined surface 7 that is inclined from the back surface of the wall panel 4 toward the lower back.

  In this case, when the inclined surface 7 inclined downward and rearward is hooked on the locked member 6, the wall panel 4 is drawn toward the rear B of the space portion 3 using the weight of the wall panel 4. The locking tool 5 is firmly locked to the locked tool 6.

  Further, in the lateral width direction G perpendicular to the hooking direction F of the latching tool 5 with respect to the latched tool 6, the lateral dimension D of the latched tool 6 is formed wider than the lateral width dimension E of the latching tool 5. Is preferred. In this case, the hooking range of the locking tool 5 is widened, and it becomes possible to cope with various differences in the spacing between the studs 2.

  In the present invention, the wall panel can be locked from the front side to the side surface side of the stud while pulling the entire wall panel toward the rear of the space between the studs. It is easy to install, improves workability, and can be easily removed and replaced during maintenance, and the front panel surface material of the wall panel with respect to the studs can be made smaller in size, greatly improving the appearance design.

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

  In this embodiment, the functional panel 4 is illustrated as an example of a long wall panel. The function panel 4 is not limited to a ventilation function panel that ventilates the room, but includes, for example, a panel with a speaker function that incorporates audio equipment, and an air purification panel that incorporates a functional material that absorbs or absorbs indoor odors and harmful substances. Various functional panels such as a radiant heating panel incorporating an electric heater and a light panel for illumination are included. Of course, the present invention is not limited to the functional panel, but can be widely applied to the entire field of long wall panels installed between adjacent studs.

  As shown in FIG. 1, the functional panel 4 includes a surface material 4 c and a back bulge portion 4 a that bulges backward B from the center side in the lateral width direction G of the back surface of the surface material 4 c. And the back surface bulging part 4a is comprised with the steel plate frame, and the ventilation functional component which ventilates a room | chamber interior is built in the inside. The height H (FIG. 3) of the entire functional panel 4 is, for example, about 1800 mm to 2500 mm, and the thickness C of the surface material 4c is, for example, about 15 mm.

  The back bulging portion 4a of the function panel 4 is accommodated in the space 3 between the adjacent studs 2, and both end portions 4b in the lateral width direction G of the surface material 4c are respectively disposed in front N of the studs 2. Is. In this example, both end portions 4b of the surface material 4c are arranged on the front end face of the stud 2 in another wall panel (hereinafter referred to as “adjacent wall panel 1”) arranged adjacent to both sides of the functional panel 4 respectively. It arrange | positions so that the wall surface 1a part to be covered may each be covered from the front N.

  The functional panel 4 is fixed to the side surface 2 a of the spacer 2 using the panel-side fixing member 8 and the spacer-side fixing member 9. A pair of left and right panel-side fixing members 8 are attached to the left and right positions on the back side of the function panel 4. Each panel-side fixing member 8 is attached to the back surface side of the surface material mounting portion 25 protruding along the back surface of the surface material 4c from the left and right ends of the back bulging portion 4a. For example, the surface material made of a rigid material It is firmly fixed to the mounting portion 25 by welding or bolting. As shown in FIG. 2, each panel-side fixing member 8 is formed of a long steel plate extending over the entire length in the longitudinal direction A of the functional panel 4, and a plurality of locking tools 5 over the entire longitudinal direction A. Are projected at almost regular intervals. The locking tool 5 of the present example is configured by a hook-shaped hook having an inclined surface 7 cut and raised from the panel-side fixing member 8 and bent in a rounded shape toward the lower back. The inclined surface 7 of the locking tool 5 serves as a hooking surface to be hooked on the locked tool 6 to be described later, and in the direction B in which the entire functional panel 4 is drawn using the weight of the functional panel 4 itself. It works to energize.

  On the other hand, as shown in FIG. 1, a pair of left and right intermediate column side fixing members 9 are fixed to the opposing side surfaces 2 a of the adjacent intermediate columns 2 so as to face the space 3 between the intermediate columns 2. As shown in FIG. 2, each of the stud-side fixing members 9 is composed of a long steel plate having an L-shaped cross section extending over the entire length in the longitudinal direction A of the stud 2, and the front piece 9 b is exposed to the front N of the space portion 3. In the state, the side piece 9a is firmly attached to the side surface 2a of the stud 2. As an attachment method, when the stud 2 is made of metal, it is fixed by welding or bolting, and when the stud 2 is made of wood, it is fixed by screwing. In this example, the front piece 9b protrudes in the horizontal direction flush with the front end face of the stud 2 and is exposed to the space 3. The front piece 9b has a plurality of engaged portions over the entire longitudinal direction A thereof. Stoppers 6 are provided at substantially constant intervals. Each locked tool 6 is formed in a horizontally-long rectangular opening shape, and is formed at a position corresponding to each of the plurality of locking tools 5. In this example, in the lateral width direction G orthogonal to the hooking direction F of the locking tool 5, the lateral width dimension D of the locked tool 6 is formed wider than the lateral width dimension E (> D) of the locking tool 5. .

  Thus, when the functional panel 4 having the above-described configuration is installed between the adjacent studs 2, the functional panel 4 is lifted and the back bulges 4 a are inserted into the spaces 3 between the studs 2, so that both ends of the surface material 4 c 4b is assigned to the wall surface 1a of the adjacent wall panel 1, and each locking member 5 of the panel side fixing member 8 fixed to the back surface of the functional panel 4 is fixed to the side 2a side of the intermediate column 2 from the front N. The functional panel 4 is dropped while being hooked on each of the locked members 6 of the member 9. As a result, the hooking surface of the locking device 5 using the weight of the functional panel 4, that is, the inclined surface 7 of the hook-shaped hook bent in a round shape toward the lower back is inserted into the locked device 6. At the same time, the entire functional panel 4 is locked by the inclined surface 7 while being drawn toward the rear B of the space 3 indicated by the arrow B in FIG. Therefore, both end portions 4b of the surface material 4c are pressed against and closely adhered to the wall surface 1a of the adjacent wall panel 1 (FIG. 1B). At this time, the panel-side fixing member 8 is firmly fixed to the surface material mounting portion 25 of the rear surface bulging portion 4 a made of a rigid frame, and the inter-column-side fixing member 9 is firmly fixed to the side surface 2 a of the inter-column 2. Since it is fixed, the hooking engagement between the locking device 5 and the locked device 6 is ensured and strong. As a result, the construction of the functional panel 4 becomes extremely easy as compared with the conventional screwing.

  In the hooked engagement state, the panel side fixing member 8 and the stud side fixing member 9 are both hidden behind the functional panel 4 and cannot be seen from the indoor side, and both end portions of the surface material 4c. 4b is pressed against the wall surface 1a of the adjacent wall panel 1 and does not float from the wall surface 1a. Therefore, the close contact state of both 4c and 1a can be maintained for a long time, and the functional panel 4 from the wall surface 1a can be maintained. The overall projecting dimension toward the front N is only the thickness C of the surface material 4c. As a result, the appearance design of the applied functional panel 4 is greatly improved as compared with conventional screwing.

  Furthermore, since the direction F (FIG. 2) in which the locking tool 5 is hooked on the locked tool 6 coincides with the direction in which the weight of the functional panel 4 acts (vertical direction), the functional panel 4 is intentionally moved. As long as it is not lifted, there is no concern that the locking tool 5 will come off from the locked tool 6, and the same fixing strength as in the case of screwing can be obtained. On the other hand, since the locking tool 5 can be easily removed from the locked tool 6 simply by lifting the function panel 4, the ease of attachment and detachment is improved as compared with the case of screwing, and maintenance can be performed. It can be easily removed and replaced.

  By the way, although the space | interval of the stud 2 is generally about 455 mm, since the dimension of the stud 2 itself exists in various sizes, the spacing between the studs 2 may vary. Therefore, in this example, since the width D of the locked tool 6 is formed wider than the width E of the locking tool 5, the hooking range of the locking tool 5 is widened. It is possible to cope with the difference in interval, and there is an advantage that the workability is further improved.

  In the embodiment of FIG. 2, the panel-side fixing member 8 is provided with the locking tool 5, and the stud-side fixing member 9 is provided with the locked tool 6, but conversely, the panel-side fixing member It is good also as a structure which provided the to-be-latched tool 6 in 8, and provided the latching tool 5 in the stud side fixing member 9. FIG. In this case, by engaging the inclined surface 7 of the hook-shaped hook constituting the locking tool 5 in a shape that is bent in a rounded shape toward the front diagonally upward direction, the locked hole-shaped locked tool 6 is engaged from the front N. When hooked on the stopper 5, the entire wall panel 4 is hooked and engaged while being pulled toward the rear B of the space portion 3 as in the above-described embodiment.

  FIG. 4 is an example of another embodiment of the locking tool 5 and the locked tool 6. In this example, the locking tool 5 is configured by a wedge-shaped locking tool 5A, and the locked tool 6 is configured by a wedge-shaped locked tool 6A. Other configurations are the same as those of the above-described embodiment, and corresponding portions are denoted by the same reference numerals. The wedge-shaped locking tool 5A of this example is composed of a plurality of rectangular blocks 10 having a narrow width dimension E protruding at intervals in the longitudinal direction of the panel-side fixing member 8, and the lower end of each rectangular block 10 is hooked. The surface is an inclined surface 10a inclined downward and rearward. On the other hand, the wedge-shaped locking tool 6A is composed of a plurality of wide rectangular blocks 10 having a lateral width D protruding at intervals in the longitudinal direction of the stud-side fixing member 9, and the upper end surface of each rectangular block 11 is the above-mentioned The wedge-shaped surface 11a is inclined in a direction parallel to the inclined surface 10a (backward and downward).

  Thus, by forming both the lower end surface of the wedge-shaped locking tool 5A and the upper end surface of the wedge-shaped locking tool 6A in a wedge shape, the wedge-shaped locking tool 5A is made in the direction of arrow F with respect to the wedge-shaped locking tool 6A. 4B, using the weight of the functional panel 4 itself, the inclined surface 10a and the wedge-shaped surface 11a are engaged with each other, and at this time, the functional panel 4 is engaged. The whole is drawn toward the rear B of the space 3 as in FIG. Also in this example, by forming the width D of the wedge-shaped locked tool 6A wider than the width E (> D) of the wedge-shaped locked tool 5A, the hook range of the wedge-shaped locked tool 5A is expanded. Thus, it becomes possible to cope with various differences in the spacing between the studs 2.

  In the embodiment of FIG. 4, the panel-side fixing member 8 is provided with the wedge-shaped locking member 5 </ b> A, and the stud-side locking member 9 is provided with the wedge-shaped locking member 6 </ b> A. The wedge-shaped latching tool 6A may be provided on the fixing member 8, and the wedge-shaped latching tool 5A may be provided on the stud-side fixing member 9.

  In each of the above embodiments, the panel-side fixing member 8 provided with the locking member 5 is configured separately from the function panel 4, but a plurality of upper and lower parts are separated from the steel plate frame constituting the back bulging portion 4a of the function panel 4. It is also possible to adopt a structure in which the locking tool 5 is integrally projected. In this case, the back bulging portion 4a itself has a structure also serving as the panel side fixing member 8, and there is an advantage that the number of parts can be reduced.

  In the embodiment, the hook-shaped hook constituting the locking tool 5 is cut and raised from the panel-side fixing member 8 or the wedge-shaped hook is integrally formed. However, the panel-side fixing member 8 and the locking tool 5 are separated. It may be constituted by a body and a method of retrofitting the locking member 5 to the panel side fixing member 8 may be used.

  By the way, as a reference example of the present invention, for example, as shown in FIG. 5, it is possible to fix the panel side fixing member 8 to the back surface of both end portions 4 b in the lateral width direction G of the surface material 4 c of the functional panel 4. In this case, both end portions 4b of the surface material 4c are floated from the adjacent wall panel 1 depending on the thickness of the panel side fixing member 8, which is not preferable in terms of design compared to the above embodiments.

  6 to 9 are examples of still another embodiment of the present invention. In this example, a hook-shaped locking tool 5B having a hook-shaped piece 15 and a vertical plate-shaped locked tool 6B having a vertical plate-shaped piece 13 are illustrated. Other configurations are the same as those of the embodiment of FIGS. 1 and 3, and corresponding portions are denoted by the same reference numerals.

  The to-be-latched tool 6B of this example is attached to several places at intervals in the up-down direction of the side surface 2a of the stud 2. As shown in FIG. 9, each locked member 6 </ b> B is integrally formed with a spacer post fixing piece 12 and a vertical plate-like piece 13 protruding in a direction orthogonal to the stud fixing piece 12 from a position near the center of the stud fixing piece 12. In the state where the screw hole portion 12a of the intermediate post fixing piece 12 is screwed to the side surface 2a of the intermediate post 2, the vertical plate-like piece 13 is located on the side J of the side face 2a of the intermediate post 2 (FIG. 6 ( It arrange | positions so that it may protrude toward a).

  As shown in FIG. 8, the locking tool 6 </ b> B of this example is attached to a plurality of locations with a space in the vertical direction on the back surface of the surface material 4 c of the functional panel 4. Each locking tool 5B is composed of an L-shaped bracket integrally provided with a panel fixing piece 14 and a hook-like piece 15 protruding in a direction orthogonal to the panel fixing piece 14 from a side end portion of the panel fixing piece 14. In the state where the screw hole portion 14a of the panel fixing piece 14 is screwed to the back surface of the surface material 4c of the functional panel 4, the hook-shaped piece 15 faces the rear B (FIG. 6A) from the back surface of the functional panel 4. It arrange | positions so that it may protrude.

  As shown in FIG. 7, the thickness K of the bowl-shaped piece 15 in this example is narrower (L> K) than the lateral width dimension L of the vertical plate-shaped piece 13 of the locked tool 6B. The upper part of the bowl-shaped piece 15 is continuous with the panel fixing piece 14, and the lower part protrudes downward from the panel fixing piece 14 with a gap 16 so that the vertical plate-like piece 13 is inserted from below the gap 16. It has become.

  Further, a pressing portion 18 is projected from the lower end of the surface of the bowl-shaped piece 15 facing the panel fixing piece 14 with a gap 16 so as to protrude toward the panel fixing piece 14. The lower surface portion of the pressing portion 18 serves as a hooking surface 17 for the vertical plate-like piece 13. The hooking surface 17 of this example is formed by an inclined surface 17 a that is inclined in a direction away from the panel fixing piece 14 as it is away from the pressing portion 18, and this inclined direction P (FIG. 7) is the back surface of the functional panel 4. It is the direction which inclines toward the back lower part from.

  When attaching the functional panel 4 of the present example, the functional panel 4 is lifted and the back bulging portion 4a (FIG. 6) of the functional panel 4 is formed in the space 3 between the studs 2 in the same manner as the embodiment of FIG. In the inserted state, the hook-like piece 15 of the locking member 5B on the surface material 4c side is hooked in the direction of the arrow F in FIG. 7 with respect to the vertical plate-like piece 13 of the locked member 6B on the side pillar 2 side. Drop panel 4. At this time, the hooking surface 17 at the lower end of the hook-like piece 15 slides down from the upper end of the vertical plate-like piece 13 to the back surface 13a of the vertical plate-like piece 13 in the direction indicated by the arrow t in FIG. The vertical plate-like piece 13 is fitted in the gap 16 between the panel 15 and the panel fixing piece 14. At this time, the pressing portion 18 located at the upper end of the hooking surface 17 of the hook-shaped piece 15 is in a state of being pressed against the back surface 13a of the vertical plate-shaped piece 13 so as to draw the functional panel 4 backward B. As a result, the functional panel 4 is fixed at a position drawn toward the rear B of the space 3, and both end portions 4 b of the surface material 4 c are pressed against and closely adhered to the wall surface 1 a of the adjacent wall panel 1 (FIG. 6B). ) State).

  Thus, the engagement between the hook-shaped locking tool 5B and the vertical plate-shaped locked tool 6B suppresses the protruding dimension of the surface material 4c of the functional panel 4 with respect to the stud 2 to the front N, while reducing the function. The panel 4 can be fixed to the intermediate pillar 2 very easily. Moreover, the hooking direction F (FIG. 7) of the locking tool 5B is the direction in which the weight of the functional panel 4 acts (vertical direction). Because it matches, it can be hooked using the weight of the function panel 4 itself, and the workability is further improved compared to the case of screwing, and it is easy to remove and replace during maintenance. There is an advantage that can be.

  Moreover, since the to-be-latched tool 6B and the latching tool 5B can be hooked and latched using the space part 3 on the side J of the side surface 2a of the stud 2, the surface material 4 c of the functional panel 4 is attached to the front face of the stud 2. It is easy to dispose as close as possible to the side, and the locked tool 6B and the locking tool 5B are hidden behind the functional panel 4 and cannot be seen from the indoor side, which is preferable in terms of design.

  Incidentally, the fixing with the fixing screw 20 as shown in FIG. 10 (a) takes time for attaching and detaching, and the screw head of the fixing screw 20 is exposed on the surface of the functional panel 4 to deteriorate the design. On the other hand, even when the screw head is covered with the joint material 21 as shown in FIG. 10B, the design of the functional panel 4 is lowered by the joint material 21. The tool 5 (5B) and the locked tool 6 (6B) are both preferable in terms of ease of attachment / detachment and design.

  Further, in this example, the horizontal width L of the vertical plate-like piece 13 is formed to be wider (L> K) than the thickness K of the hook-like piece 15, so that the hook-like piece 15 is pulled with respect to the vertical plate-like piece 13. There is also an advantage that the hanging range is widened, and this makes it possible to cope with various differences in the spacing between the studs 2.

  In the present embodiment, the case where a plurality of locking tools 5B and a plurality of locked tools 6B are used has been described. For example, the panel fixing piece 14 is formed in a vertically long shape, and the length of the panel fixing piece 14 is increased. A plurality of hook-like pieces 15 are integrally formed with a space in the vertical direction to form a single locking tool 5B, and the stud fixing piece 12 is formed in a vertically long shape. It is also possible to form a single locked tool 6B by integrally forming a plurality of vertical plate-like pieces 13 with an interval in the vertical direction.
