Description

  The present invention is an interior panel connection structure that is constructed on the ceiling or wall of a unit room, and an interior panel is formed by sticking a backing material to the back surface of the panel body, and the rear edge of the panel body is directed to the rear side. Concerning an interior panel connection structure in which bent connection parts are formed, the connection parts are opposed to each other between adjacent interior panels, and a reinforcing bar material is sandwiched and fixed between the two interior panels. It is.

  Conventionally, in the ceiling of a unit room such as a general bathroom, toilet room, sanitary room, etc., as shown in FIGS. A connecting portion 3 is formed at the edge of the panel body 1 so as to bend and protrude toward the rear side. The connecting portions 3 are opposed to each other between adjacent interior panels B, and a reinforcing bar member 4 is sandwiched and fixed therebetween. An interior panel connection structure in which both interior panels B are connected is adopted and constructed.

  In this case, the connection part 3 formed in the edge part of the panel main body 1 is the protrusion plate piece shape bent to the back back side, and the through-hole (not shown) is drilled in this connection part 3. . Further, the reinforcing bar member 4 is a metal strip plate material thicker than the panel body 1, and the reinforcing bar member 4 is also provided with a through hole (not shown). Then, as shown in FIG. 5 (a), a reinforcing bar member 4 is interposed between the opposing connecting portions 3, and bolts 10 are inserted into the through holes formed in the connecting portions 3 and the reinforcing bar member 4. As shown in FIG. 5 (b), the reinforcing bar member 4 is sandwiched and fixed between the connecting portions 3 by screwing and tightening a nut 11 to the bolt 10. Therefore, in this interior panel connection structure, the connection portion between both interior panels B is reinforced by the reinforcing bar member 4.

  However, in this case, since the edge portion of the panel main body 1 is a protruding plate piece-like connecting portion 3 that is bent backward only once, the rigidity of the connecting portion 3 is low, and between the connecting portions 3 Even if the reinforcing bar member 4 is sandwiched and fixed, it is difficult to obtain a sufficient reinforcing effect. Moreover, since the bolts 10 and nuts 11 are clamped and fixed for connection, the screwing operation is troublesome, and the connection work at the time of construction is troublesome.

  In addition, a space S is required inside each of the connection portions 3 for screwing the bolts 10 and nuts 11, and the backing material 2 has its side end 2 a separated from the connection portion 3 by the space S. Therefore, the strength in the vicinity of the connection site is reduced. In this case, as shown in FIG. 4, even if the reinforcement wood 9 is used for further reinforcement, the reinforcement wood 9 to be attached to the back side back surface 2 b of the backing material 2 is brought close to the connection portion 3. Therefore, it was difficult to fix, and it was difficult to reinforce the vicinity of the connection site.

  Incidentally, there is also known a unit room ceiling fixing structure in which connection work can be easily performed regardless of screwing operation (Patent Document 1: Japanese Patent Laid-Open No. 10-37499). In this case, as shown in FIG. 6, a backing material 2 is attached to the back surface of the panel body 1 to form interior panels C1 and C2, and the connecting portions 3 of both interior panels C1 and C2 are overlapped in the front and back. The joiner 15 is joined and slid on the rear side of the engaging portion so that the connecting portions 3 can be easily connected to each other.

  In this case, a U-shaped reinforcing member 12 having a U-shaped cross section is fixed to the connecting portion 3 of one interior panel C1, and a plurality of locking projections 6 are arranged and protruded on the back surface of the reinforcing member 12 in the longitudinal direction. Yes. The connecting portion 3 of the other interior panel C2 is formed as a bent plate-like piece 13 in which the edge portion of the panel body 1 is bent rearwardly and outwardly in an L-shaped cross section. A plurality of engagement holes 14 are arranged and formed in the rear piece portion corresponding to the locking projections 6. The joiner 15 is made of a die having a U-shaped cross section that is open to the back, and a plurality of dharma-shaped long holes 5 are arranged in the bottom piece portion corresponding to the locking protrusions 6 and the engaging holes 14. Has been.

  Then, in the connection work at the time of construction, first, as shown in FIG. 6A, the bent plate-like piece 13 of the other interior panel C2 is superimposed on the back side of the reinforcing mold member 12 of one interior panel C1, The engaging hole 14 is fitted and engaged with the locking protrusion 6. Next, as shown in FIG. 6 (b), the Dalma-shaped long hole 5 is inserted into the locking projection 6 inserted through the engaging hole 14, and the joiner 15 is attached to the back side of the bent plate-shaped piece 13. The joiner 15 is slid in the longitudinal direction. As a result, as shown in FIG. 6 (c), the dharma-shaped long hole 5 is locked to the locking protrusion 6 via the engaging hole 14, and the reinforcing mold 12 and the bent plate-shaped piece 13 are connected by the joiner 15. Is done. Here, as shown in FIG. 6C, the joiner 15 can be easily attached and detached by sliding the joiner 15 with a slide jig 16.

However, in this case, since the joiner 15 for connecting the two interior panels C1 and C2 and the reinforcing mold member 12 for reinforcing the connection portion are required as separate members, the cost increases due to an increase in the number of members. . Moreover, since the reinforcing mold 12 is fixed only to the connection part 3 of one interior panel C1, the other connection part 3 is not sufficiently reinforced, and the structure of the connection part 3 of both interior panels C1 and C2 However, the manufacturing side and the member management side become complicated. In addition, the work of joining the connecting portions 3 of both the interior panels C1 and C2 and the work of sliding the joiner 15 and connecting them are performed separately, and the connection work at the time of construction is not so simplified. .

In the interior panel connection structure of this embodiment, a backing material 2 is adhered to the back surface of the panel body 1 to form an interior panel A, and the connection portion 3 that is bent and protrudes toward the rear back side at the edge portion of the panel body 1 is provided. The inner panel A is formed and connected to each other, and the connecting portions 3 are opposed to each other, and the reinforcing bar member 4 is sandwiched and fixed therebetween to connect the inner panels A.

  And in the interior panel connection structure of this embodiment, the hollow substantially rectangular connection part 3 bent at a substantially right angle from the rear, inward, and forward is formed at the edge portion of the panel body 1 so as to protrude to the rear back side. Then, a plurality of dharma-shaped long holes 5 are arranged and drilled in the longitudinal direction in the outer piece 3a bent rearward of the connecting portion 3, and a plurality of locking projections 6 are formed on both side surfaces of the reinforcing bar member 4 as described above. The reinforcing bar material 4 is interposed between the outer pieces 3a of the two connecting portions 3 facing each other, and the locking protrusions 6 are inserted into the respective dharma-shaped long holes 5. The reinforcing bar member 4 is slid and fixed to the dharma-shaped long holes 5 by sliding the reinforcing bar member 4 so that the reinforcing bar member 4 is sandwiched and fixed between the outer side pieces 3a.

  Further, in the interior panel connection structure of this embodiment, the side end 2a of the backing material 2 is brought into contact with the inner piece 3c bent forward of the connection part 3, and in this case, the inner side of the connection part 3 The back side middle piece 3b and the back side back surface 2b of the backing material 2 are also made to be substantially flush with each other. Furthermore, the longitudinal direction of the dharma-shaped long hole 5 is aligned with the longitudinal direction of the outer piece 3 a, and the reinforcing bar member 4 is slid in the longitudinal direction so that the locking projections 6 are locked to the respective dharma-shaped long holes 5. As described above, the rear edge 4a of the reinforcing bar member 4 protrudes rearward from the connecting portions 3 of the panel bodies 1 on both sides.

  Hereinafter, the interior panel connection structure of this embodiment will be described in more detail. The interior panel connection structure of this embodiment is adopted and installed on the ceiling of a unit room such as a bathroom, toilet room, and sanitary room. The panel body 1 is made of a metal plate such as a decorative steel plate or a stainless steel plate, a resin-coated metal plate, or a resin molded plate, and is formed in a substantially rectangular shape having a size that divides the ceiling into a plurality of pieces. A connecting portion 3 is integrally provided over an almost entire length of an edge portion of the panel body 1 where the interior panel A is adjacently disposed. The connecting portion 3 includes an outer piece 3a, a rear middle piece 3b, and an inner piece 3c. The end portion of the panel body 1 is formed by extending and bending to the back side so as to have a hollow substantially rectangular cross section surrounded by.

  Further, as shown in FIG. 1, an attaching piece portion 7 bent forward is formed integrally on the other edge portion adjacent to the connecting portion 3 of the panel body 1 over the substantially entire length thereof. A long hole 8 for mounting is arranged and drilled in the attachment piece 7. In this case, the attachment piece 7 is connected and fixed to a wall panel (not shown) constituting the unit room by a screw (not shown) inserted through the attachment long hole 8. In the outer piece 3a of the connection portion 3 of the panel body 1, a plurality of dharma-like long holes 5 are arranged and drilled in the longitudinal direction, and each dharma-like long hole 5 has a large diameter portion 5a and a small diameter portion 5b. The Dalma-shaped long holes 5 are arranged so that the longitudinal direction in which the large-diameter portion 5a and the small-diameter portion 5b are aligned is the same along the longitudinal direction of the outer piece 3a. .

  A backing material 2 is adhered and fixed to the back surface of the panel body 1 over substantially the entire surface. At this time, a side end 2a of the backing material 2 is brought into contact with an inner piece 3c of the connection portion 3, The backing material 2 is accurately positioned at a predetermined position and is easily stuck and fixed. The backing material 2 is made of gypsum board or resin foam, and reinforces the panel body 1 and also has a heat insulating effect. Further, the back side back surface 2b of the backing material 2 in which the side end portion 2a is in contact with the inner piece 3c of the connecting portion 3 is substantially flush with the rear middle piece 3b of the connecting portion 3 and is continuous with FIG. As shown in FIG. 3, the reinforcing wood 9 can be stuck and fixed so as to straddle the back side rear surface 2b and the rear middle piece 3b. In this case, the reinforcing wood 9 is made of a wooden square, and can be easily stuck and fixed close to the reinforcing bar 4 described later.

  The reinforcing bar member 4 is a belt-like metal plate or resin plate that is thicker than the panel body 1 and has a length dimension that extends over substantially the entire length of the connecting portion 3. Further, the width dimension of the reinforcing bar member 4 is larger than the width dimension of the outer piece 3a of the connecting portion 3, and the rear edge 4a of the reinforcing bar member 4 is more than the rear middle piece 3b of the connecting portion 3 on both sides. Is projected rearward, and the projecting dimension is set to such an extent that it can be gripped by the hand. Further, on both side surfaces of the reinforcing bar member 4, a plurality of locking projections 6 are arranged and protruded in positions corresponding to the dharma-shaped long holes 5 in the longitudinal direction. The locking projections 6 are formed in a substantially cylindrical shape with an enlarged front end side, and are projected integrally with the reinforcing bar member 4 or bonded and fixed. In this case, the latching protrusion 6 is inserted from the large-diameter portion 5a of the dharma-shaped long hole 5, is slid to the small-diameter portion 5b, and is latched to the hole edge of the small-diameter portion 5b.

  Here, the connection work in the interior panel connection structure of this embodiment will be specifically described step by step. First, as shown in FIGS. 1 and 2A, the connection portions 3 of the two interior panels A arranged adjacent to each other are opposed to each other, and the reinforcing bar material 4 is interposed between the connection portions 3. And each latching protrusion 6 of the reinforcement bar material 4 is inserted into each dharma-shaped long hole 5 of the connection part 3 from the large diameter part 5a, and the reinforcement bar material 4 is slid along the longitudinal direction (FIG. 1α). Slide in the direction). As a result, the locking projection 6 moves to the small-diameter portion 5b of the Dalma-shaped long hole 5, and is locked to the hole edge of the small-diameter portion 5b so as not to come off, as shown in FIG. 2 (b). Then, the reinforcing bar member 4 is sandwiched and fixed between the outer pieces 3a of the connecting portions 3, and the connecting operation is completed.

  In this case, since the outer peripheral surface of the locking projection 6 formed in a substantially columnar shape is formed in a taper shape that is enlarged toward the tip side, the Dalma-shaped long hole 5 is widened from the large diameter portion 5a to the small diameter portion 5b. If the diameter dimension is formed so as to be gradually reduced, the reinforcing bar member 4 is slid in the direction of FIG. The connecting portion 3 is attracted to the reinforcing bar member 4, and the reinforcing bar member 4 is firmly clamped and fixed between the outer pieces 3 a of both connecting portions 3.

  Therefore, in the interior panel connection structure of this embodiment, the hollow substantially rectangular connection portion 3 bent at a substantially right angle from the edge portion of the panel body 1 to the rear, inward, and forward is integrated into the rear back side. The end portion of the panel body 1 is increased in rigidity by the hollow substantially rectangular connecting portion 3 so that it is difficult to bend and deform. By connecting the two interior panels A with the same connecting portions 3 facing each other between A and sandwiching and fixing the reinforcing bar member 4 between them, the reinforcing rigidity at this connecting portion is sufficiently secured.

  In addition, the reinforcing bar material 4 is interposed between the outer pieces 3a of the opposite connecting portions 3 and the engaging protrusions 6 are inserted into the respective dharma-shaped long holes 5, and the reinforcing bar material 4 is slid. Thus, the reinforcing bar material 4 is sandwiched and fixed between the outer side pieces 3a by locking the locking protrusions 6 in the respective dharma-shaped long holes 5, so that the reinforcing bar material 4 has both functions of connection and reinforcement. As a result, the connecting work is completed by a simple operation of interposing the reinforcing bar material 4 between the connecting portions 3 and sliding the reinforcing bar material 4 between the connecting portions 3, and the connecting work is simplified.

  In this case, the reinforcing bar member 4 is slid in the opposite direction (the opposite direction to FIG. 1α) in the connected state, so that the reinforcing bar member 4 is connected to the two connecting portions 3 in the reverse operation. It is possible to disassemble both interior panels A by removing them from the space. In the interior panel connection structure of this embodiment, since the reinforcing bar member 4 is also used as a joiner (joiner 15 in the conventional example shown in FIG. 6), the number of members can be reduced, and both connecting portions 3 facing each other can be provided. Since it becomes the same structure, manufacture of interior panel A and member management are easy, and it can aim at cost reduction by this.

  Furthermore, in the interior panel connection structure of this embodiment, the side edge 2a of the backing material 2 is brought into contact with the inner piece 3c bent forward of the connecting portion 3, so that the backing material 2 is made of the inner piece 3c. And is easily attached and fixed to the back surface of the panel body 1 at a predetermined position. In addition, in this case, since the connecting portion 3 and the backing material 2 that are joined to each other integrally perform a reinforcing action, the strength in the vicinity of the connecting portion is sufficiently ensured. Further, since the rear middle piece 3b bent inward of the connecting portion 3 and the back side rear face 2b of the backing material 2 are substantially flush with each other, the continuous back side rear face 2b and the rear side middle piece 3b are continuous. The reinforcing wood 9 can be stuck and fixed so as to straddle and the vicinity of the connection portion can be more reliably reinforced by sticking and fixing the reinforcing wood 9 close to the reinforcing bar material 4. .

  Moreover, in the interior panel connection structure of this embodiment, the longitudinal direction of the dharma-shaped long hole 5 is set along the longitudinal direction of the outer piece 3a, and the reinforcing bar member 4 is slid in the longitudinal direction to thereby form each locking projection. Since 6 is locked to each of the dharma-shaped long holes 5, it becomes a simple operation of sliding the reinforcing bar member 4 in the longitudinal direction thereof, and a large work space is required for sliding sliding. And not. In addition, at that time, the rear edge 4a of the reinforcing bar member 4 protrudes rearward from the connecting portions 3 of the panel main bodies 1 on both sides. It can be easily slid.

  Further, in this case, the front side edge portion of the reinforcing bar member 4 does not protrude forward from the surface of the panel body 1 and does not hinder the appearance. In the present invention, the front side edge portion of the reinforcing bar member 4 protrudes forward from the surface of the panel body 1 and the protruding portion is gripped by the hand to slide the reinforcing bar member 4. Well, in this case, the connection work in the construction from the indoor side of the interior panel A becomes easy.
