As shown in FIGS. 1 and 2, the cover panel mounting structure of the present embodiment has an existing ceiling plate 1, a hollow wall surface material, or the like as a base surface, and the ceiling plate 1, the wall surface material, or the like is used as a ground surface material. Without removing, a plurality of cover panels 2A and 2B are combined with the base surface 1A, and the vertical joint 3A and the horizontal joint 3B are formed between the adjacent cover panels 2A and 2B by the vertical joint separator 30A and the horizontal joint separator 30B. The base surface 1A is covered with makeup. This cover panel mounting structure is roughly divided into a mounting member 4A and cover panels 2A and 2B.

  As shown in FIG. 1, the attachment member 4 </ b> A is fixed at the position of the base surface corresponding to the vertical joint portion 3 of the adjacent cover panels 2 </ b> A and 2 </ b> B. The attachment members 4A are arranged at predetermined intervals according to the length of the cover panels 2A and 2B in the vertical direction (front-rear direction). For example, in the case of a cover panel having a longitudinal length of about 1300 mm, the cover panels are arranged at a pitch of about 800 mm.

  As shown in FIGS. 3 and 4, each mounting member 4 </ b> A has a cross-sectional hat shape as viewed from the side from a protrusion 5 having a U-shaped cross section at the center and a mounting flange 6 extending horizontally outward on both left and right sides thereof. Is formed.

  The mounting flange 6 is fixed to a lower ground material such as the ceiling board 1 by inserting a known board fastener 7 into the mounting hole 6a.

  The top surface of the projecting portion 5 has a function of ensuring a space in which the cable line or the like can be wired between the cover panel and the base surface by contacting the cover panels 2A and 2B. For example, the height of the protrusion 5 can be set to a height of about 10 mm to 25 mm where a cable line or the like can be wired. In addition, engaging claws 8 and 9 for removably engaging the engaging holes 10 and 11 of the cover panels 2A and 2B and attaching the cover panels 2A and 2B to the base surface are provided on the top surface of the protrusion 5. Is rotatably provided.

  The engaging claws 8 and 9 are thin plate-shaped, and are provided in a pair in the vertical direction so that they can be engaged with the engaging holes 10 and 11 of both adjacent cover panels. The engaging claws 8 and 9 are set such that the distal end side protrudes outward in the left-right direction from the vertical joint portion 3A, and the proximal end side is rotatably supported by the protruding portion 5 via the shafts 12 and 13. The

  The shafts 12 and 13 have, for example, heads 12a and 13a that protrude downward from the engaging claws 8 and 9 using a slotted flat machine screw (the upper side in FIG. It will be down.) The heads 12a and 13a of the shafts 12 and 13 are sandwiched between the side walls 18 of the left and right cover panels 2A and 2B to function as a vertical joint separator 30A, and a vertical joint 3A is formed between the left and right cover panels 2A and 2B.

  Further, when the engaging claws 8 and 9 are rotated, the shafts 12 and 13 constituted by screws are engaged by friction between the screw portions and the screw holes of the projections 5 to be screwed together. It functions as a detent for the claws 8 and 9.

  In order to form the vertical joint 3A, in this example, the heads of the shafts 12 and 13 are used. Alternatively, a separator 30A for forming the vertical joint may be provided.

  Further, in the engagement posture in which the engagement claws 8 and 9 are rotated in the left and right direction, a detent plate 15 is interposed between the shafts 12 and 13 as a detent stopper for the engagement claws 8 and 9. . The detent plate 15 is formed in a long plate shape corresponding to the length between the engaging claws in the engaging posture of the engaging claws 8 and 9, and is set to a width corresponding to the width of the joint portion 3A. Then, the central portion thereof is fixed to the protruding portion 5 with a screw 16.

  On the other hand, each cover panel 2A, 2B is formed in a rectangular shape from a thin plate made of aluminum, for example. The sizes of the cover panels 2A and 2B are set, for example, such that the length in the vertical direction (front-rear direction) is about 1300 mm and the width in the horizontal direction (left-right direction) is about 300 mm.

  Since each cover panel 2A, 2B is formed from a thin plate made of aluminum, the weight is reduced, the load applied to the existing ceiling material is small, and there is little risk of falling. Even if it falls, it will not lead to a major accident.

  Further, when the cover panels 2A and 2B are used for covering the ceiling, the decorative surface 17 is surface-treated, for example, in a silver color so that lighting efficiency can be improved.

  Each of the cover panels 2A and 2B has a decorative surface 17 on the front side, and left and right outer peripheral edges corresponding to the mounting member 4A are bent on the back side to form a thin plate-like side wall 18. Further, the outer end of the side wall 18 is bent inward to form the reinforcing rib 24, and an end portion having a U-shaped cross section is formed as the entire cover panel.

  The height of the side wall 18 of the cover panels 2A and 2B is set to about 10 mm to 20 mm, for example. Further, the reinforcing rib 24 can be brought into contact with the top surface of the protrusion 5 of the mounting member 4A. By securing a predetermined space between the decorative surface and the base surface of the cover panels 2A and 2B by the side wall 18 (for example, a height of 10 mm to 20 mm) and the protrusion 5 (for example, a height of 10 mm to 25 mm), The wiring of the cable line 23 etc. is possible in the inside.

  A sufficient space (for example, a height of 10 mm) is provided between the top surface of the projection 5 of the mounting member 4A and the ground surface so that the cable wire 23 is placed in the space between the cover panels 2A and 2B and the ground surface. However, in order to facilitate the introduction of the cable line, a notch 27 into which the cable line can be introduced may be formed in a part of the side wall 18 as shown in FIG. . Of course, the cable wire can be introduced between the cover panels 2A and 2B and the base surface without the cutout 27.

  On the other hand, as shown in FIG. 2, the front and rear edges of the cover panels 2A and 2B have no side walls such as the left and right side walls 18 and are open, which is sufficient to fold the cable wires 23. Space is secured. Of course, even if there are side walls similar to the left and right side walls 18 at the front and rear edges of the cover panels 2A and 2B, a cable wire can be introduced between the top surface of the projection 5 of the mounting member 4A and the base surface. There is no problem because sufficient space is secured.

  Such cover panels 2A and 2B are formed by bending the left and right ends of one thin plate into a U-shaped cross section. However, the notches 27 and engagement holes 10 and 11 described later are formed at the stage before the side wall 18 is formed. It is desirable to form when a single thin plate is press-molded.

  In FIG. 1, an opening 28 for installing the lighting fixture is formed in the cover panel 2 </ b> B of the cover panel 2 </ b> A, 2 </ b> B where the lighting fixture is installed.

As shown in FIG. 6, the reinforcing support member 4 </ b> B is formed in a hat shape in cross section from a central projecting portion 33 having a U-shaped cross section and mounting flanges 34 formed at both ends thereof. The height of the protrusion 33 is set to the height from the base surface to the decorative surface of the cover panel, so that the decorative surface can be reinforced.

  Further, the engagement holes 10 and 11 for releasably engaging the engagement claws 8 and 9 with the side walls 18 of the cover panels 2A and 2B at positions facing the engagement claws 8 and 9 of the mounting member 4A. Is formed. The engagement holes 10 and 11 are formed corresponding to the fixing positions of the mounting members 4A. For example, when the attachment member 4 </ b> A is installed in two places in the vertical direction (front-rear direction), the engagement holes 10, 11 are formed in two places in the vertical direction (front-rear direction) of each side wall 18.

  Each attachment member 4A is provided with a pair of engagement claws 8, 9, one of which is in the engagement hole 10 of the cover panel 2A on one side (for example, the right side) and the other engagement claw. 9 is engaged with the engaging holes 11 of the cover panel 2B on the other side (for example, the left side) adjacent to each other, and is attached to the lower ground of the ceiling material or the like via the attachment member 4A. Therefore, it is sufficient that one engagement hole 10 or 11 is formed in the side wall 18 corresponding to one engagement claw 8 or 9 of each attachment member 4A. In this example, the cover panel is shared. Therefore, a pair of engagement holes 10 and 11 are formed in the side wall 18 corresponding to the pair of engagement claws 8 and 9 of the attachment member 4A. In each of the cover panels 2A and 2B, the attachment members 4A are arranged at two positions in the vertical direction of the side wall, so that a total of two pairs of the engagement holes 10 and 11 are formed in the vertical direction of the side wall 18. Become.

  Each of the engagement holes 10 and 11 is formed in a rectangular shape that is long in the vertical direction, and the plate-like engagement claws 8 and 9 can be rotated and inserted. The engagement holes 10 and 11 can be formed by stamping and forming from a single thin plate in the previous stage of forming the side walls 18 of the cover panels 2A and 2B.

  In this way, by engaging the engagement claws 8 and 9 of the mounting member 4A with the engagement holes 10 and 11 of the cover panels 2A and 2B relative to each other, the cover panels 2A and 2B are placed under the ceiling material 1 and the like. The ground can be covered.

  Further, end and corner panels 2C and 2D are provided at the end and corner of the lower ground such as the ceiling. As shown in FIG. 5, the end and corner panels 2C and 2D are formed by bending a thin aluminum plate into a U-shaped cross section, and the portions facing the cover panels 2A and 2B are further inside. And is arranged at the end or corner of the base surface. These panels 2C and 2D are fixed to the base surface together with the horizontal joint separator 30B by using a board fastener 32 that fixes the horizontal joint separator 30B to the base surface.

  Further, a horizontal joint 3B is formed between the cover panels arranged in the front-rear direction. As shown in FIGS. 1 and 5, the horizontal joint separator 30 </ b> B that forms the horizontal joint is fixed to the base surface where the left and right cover panels 2 </ b> A and 2 </ b> B intersect. It consists of an L-shaped separator. The thickness of the vertical portion of the horizontal joint separator 30B is set to the width of the horizontal joint 3B. The horizontal base of the horizontal joint separator 30B is fixed to the base surface together with the end panel 2C and the corner panel 2D by the board fastener 32.

  The assembly direction of the cover panel will be described. First, the end panel 2C and the corner panel 2D are fixed to a lower ground such as a ceiling material together with the horizontal joint separator 30B. Next, the mounting member 4A and the reinforcing support member 4B are fixed to predetermined positions on the base surface by the board fastener 7. Then, while the cover panel 2A is made to correspond to the end panel 2C, the cover panel 2A is pressed against the protrusion 5 of the attachment member 4A, and the engagement claw 8 of the attachment member 4A is rotated to engage the engagement hole in the side wall 18 of the cover panel 2A. 10 is engaged.

  Next, the engaging claw 9 is rotated by being engaged with the engaging hole 11 of the cover panel 2B adjacent to the left and right and the engaging claw 9 of the mounting member 4A to be engaged with the engaging hole 11. Thereafter, a locking plate can be screwed between the engaging claws 8 and 9 in the locked state to prevent the engaging claws 8 and 9 from rotating inadvertently. It is possible to prevent the cover panel 2A and 2B from coming loose. These operations are sequentially repeated so that the cover panels 2A and 2B are covered with the entire base surface.

  In this manner, the cover panel can be attached sequentially in units of one sheet. Further, the cover panel can be easily removed by removing the detent plate and rotating the engagement claw 8 or 9 on the side to be removed.

  In addition, by providing a pair of engaging claws for attaching the left and right cover panels to the same attachment member, the number of attachment members can be reduced and workability can be improved.

  Moreover, since the covering decorative surface by such a cover panel is provided with the vertical joint separator 30A and the horizontal joint separator 30B, the cover panels 2A and 2B should be arranged with a predetermined joint width (for example, about 5 mm to 7 mm). Can do. And since the head which protrudes from the axial parts 12 and 13 of the engaging claws 8 and 9 is utilized as 2 A of vertical joint separators, it becomes unnecessary to prepare a vertical joint separator intentionally.

  Further, the covering of the base surface by the cover panels 2A and 2B is performed via the mounting member 4A, and can be easily attached to the base surface by the rotation operation of the engaging claws 8 and 9. Significantly better.

  Accordingly, the cover panel can be covered with the existing ceiling material (for example, gypsum board) without removing it, so that the existing ceiling material does not need to be scrapped and the heat insulation performance of the ceiling surface is impaired. The construction can be done in a short period of time.

  In addition, since a predetermined space (for example, a space of about 20 mm) is formed between the cover panel and the lower ground such as the existing ceiling material, a LAN cable such as an electric wire or a computer can be used when replacing or newly installing a lighting fixture. Can be laid.

  Of course, the present invention is not limited to the above-described embodiment, and many modifications and changes can be made within the scope of the present invention. For example, in the above-described embodiment, the cover panel is illustrated with a shape in which side walls are provided on the left and right sides and the front-rear direction is opened, but a structure having side walls on all three sides or four sides may be employed.

  Moreover, in the said embodiment, although the space which introduce | transduces a cable wire was formed between the decorative surface and the base surface of the cover panel by the attachment member and the side wall of the cover panel, it can respond by forming the side wall of the panel high. it can. As another method, the height of the mounting member with which the cover panel abuts may be increased so as to form a space for holding the cable wire.

  Further, the rotation stopper is not limited to the plate structure in the above example, and may be a structure in which a screw or the like for restricting the rotation of the engaging claw is screwed into the screw hole of the mounting member. Furthermore, the fixing of the mounting member to the lower ground may be a tap screw in addition to the board fastener.
