Description

  Since the present invention is constructed without using screws or the like in a joint structure between a ceiling panel and a wall panel, particularly in a unit bathroom or other unit room to be attached after the building frame is completed, the construction becomes easy. Further, the present invention relates to a joint structure between a ceiling panel and a wall panel, which can make a unit room wider because a space corresponding to the length of a leg such as a screw is unnecessary.

In recent years, unit-type indoors that are attached to a building frame such as a unit bathroom are often formed.
JP-A-7-252907 (6th page, FIG. 1)

  The one described in Patent Document 1 is to attach a lighting fixture to a ceiling panel, and is formed on an arch to give strength to the ceiling panel. However, this is a special one, and as shown in FIG. 4 of the present application, the wall panel 1 is usually formed by extending and bending the surface material of the wall panel 1, such as a decorative steel plate, which is the surface material of the base material. An L-shaped metal fitting provided at the upper end of the metal plate and a metal fitting provided with a downward projecting portion of the surface metal plate extending outward from the ceiling panel 2 having a metal plate on the surface are coupled by screws 5. Next, the ceiling panel and the wall panel are joined by pushing a peripheral edge formed of an elastic body of rubber or plastic into a space generated between the ceiling panel and the wall panel.

  In this case, since the ceiling panel 2 and the wall panel 1 are joined with the screws 5, a space in which the legs of the screws 5 can be accommodated between the housing 7 and the wall panel 1 is required. Without this space, the screws are not tightened properly, causing various problems. At the same time, a dead space corresponding to the length of the legs of the screws 5 is generated between the building housing 7 and the wall panel 1, and the work is performed with the screws 5. It takes time and effort.

In order to solve the above-mentioned problem, the first characteristic configuration of the joint structure of the ceiling panel and the wall panel according to the present invention is an inverted L type having a protruding piece on the upper back surface of the wall panel as described in claim 1. A wall panel with the ceiling plate mounting brackets mounted so that the protruding pieces project indoors toward the interior by a predetermined distance above the wall panel is erected along the building frame, and the surface edge of the ceiling panel is outside the ceiling panel. After fitting the bent piece of the ceiling panel that protrudes in the direction toward the top and the top part of the ceiling panel to the upper side of the wall panel and the ceiling plate mounting bracket, The groove is fitted to the protruding piece of the ceiling plate mounting bracket to fix the ceiling panel.
According to the second characteristic configuration, a sawtooth portion is provided on the lower surface of the protrusion piece of the inverted L-shaped ceiling plate mounting bracket attached to the wall panel in addition to the first characteristic configuration. There is in point.
The third characteristic configuration is that, as described in claim 3, a waterproof seal is provided between the upper portion of the wall panel and the surface protrusion of the ceiling panel having the bent pieces.

  The joint structure of the ceiling panel and the wall panel according to claim 1 is the above-mentioned structure, and unlike the conventional example, the screw is not used for joining the ceiling panel and the wall panel, so the screw leg is stored between the building frame and the wall panel. Space is not required. Accordingly, the space for housing the screw legs is not required, and the dead space for forming the unit room is reduced. Therefore, the room formed can be widened, and the installation is facilitated because no screws are used.

  Since the joining structure of the ceiling panel and the wall panel according to claim 2 is the above-mentioned structure, there is a sawtooth portion on the lower surface of the protruding piece provided on the inverted L-type ceiling panel mounting bracket attached to the wall panel. Even if an attempt is made to move, the ceiling fixing piece does not fall off due to the sawtooth portion, and the ceiling panel does not fall.

  Since the joining structure of the ceiling panel and the wall panel according to claim 3 is the above-mentioned structure, since there is a water-stopping packing, water or water is put on the back surface of the wall panel by the water-stopping packing even in a place where water is used such as a unit bathroom. Steam does not turn. Therefore, even if the heat insulation is deteriorated due to the water absorption of the heat insulating material and the space between the building frame and the wall panel is narrowed and the air permeability is poor, the generation of wrinkles can be prevented.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of a joint structure of a ceiling panel 2 and a wall panel 1 according to the present invention. The wall panel 1 is formed of a relatively hard plate material such as a glass fiber plate, a cocoon plate, or a gypsum board, and its surface is decorated by attaching a decorative steel plate or the like.

  On the upper back surface of the wall panel 1, a protruding piece 12 formed by bending a ceiling plate mounting bracket 11 having an inverted L-shaped cross section is attached to the indoor side over the entire length of the wall panel 1. There is a predetermined space between the wall panel 1 and the protruding piece 12 so that the bent piece 23 of the ceiling panel 2 can be fitted, and the mounting bracket 11 protrudes above the wall panel 1.

  The ceiling panel 2 is made of a heat insulating material 21 such as glass fiber, rock wool or the like, and a hard decorative material 22 such as a decorative steel plate or a plastic plate is bonded to the surface of the ceiling panel 2 to make up. At the side edge of the ceiling panel 2, the decorative material 22 on the surface protrudes outward from the heat insulating material 21 that is the base material of the ceiling panel 2, and the tip of the protruding portion 24 of the ceiling panel 2 is bent upward to be bent pieces 23. Is forming.

  The bent pieces 23 of the ceiling panel 2 prevent the ceiling panel 2 from being deformed during transportation or construction of the protrusion 24 of the ceiling panel 2, and can be easily inserted into the upper side of the wall panel 1. The height of the bent piece 23 is required to be high enough to fit the bent piece 23 of the ceiling panel 2 between the upper side of the wall panel 1 and the protruding piece 12 of the ceiling plate mounting bracket 11.

  Since the wall panel 1 does not use the screws 5 to mount the ceiling panel 2, it adheres to the building housing 7 using an adhesive or the like without providing a space for housing the legs of the screws 5 as shown in FIG. Can be erected.

  Next, after the ceiling panel 2 is inserted and fitted into the gap provided between the wall panel 1 and the ceiling plate mounting bracket 11 attached to the wall panel 1, the ceiling panel 2 has a U-shaped ceiling. The fixed piece 3 is inserted into the concave groove 31 so as to sandwich the protruding piece 12 of the ceiling plate mounting bracket 11. In the ceiling panel 2, the protruding portion 24 of the decorative material 22 extending outward from the ceiling panel 2 is fixed by being crimped to the upper side of the wall panel 1 and the upper side of the wall panel 1 by the ceiling plate mounting bracket 11 and the ceiling fixing piece 3. .

  The ceiling fixing piece 3 is a long material having a U-shaped cross section and is made of a hard material such as aluminum or plastic. After the ceiling panel 2 is installed, the protruding piece 12 of the ceiling fixing metal fitting 11 is sandwiched from the back side of the ceiling panel 2. By pushing, the saw-toothed portion 13 provided on the lower surface of the protruding piece 12 of the ceiling plate fixing bracket 11 is prevented from coming off.

  It is also effective to provide a water-stop packing 4 on the upper surface of the wall panel 1. For example, when water is used indoors, such as when a unit bathroom is formed, when water or steam enters the back surface of the wall panel 1, the base material constituting the wall panel 1 or the heat insulating material 21 of the ceiling panel 2 absorbs water. It promotes the generation of wrinkles because it impairs the heat insulating property of the material or has poor air permeability.

  By using the water-stopping packing 4, the protruding portion 24 of the ceiling panel 2 having the bent piece 23 of the ceiling panel 2 is pressed against the water-stopping packing 4 by the ceiling fixing piece 3, and the bent pieces 23 of the wall panel 1 and the ceiling panel 2 are moved. The space between the surface projecting portion 24 and the surface projection portion 24 is tightly closed by water-stopping packing, so that water and steam do not enter.

  In this embodiment, the heat insulating material 21 is used as the base material of the ceiling panel 2. However, when there is a concrete slab above the condominium or the like, the heat capacity of the slab is large, so the heat insulating material 21 is not necessarily required and the wall panel. Even if the ceiling panel 2 is formed of the same base material as that of No. 1, there is no problem.

  Thus, in this invention, since the ceiling panel 2 and the wall panel 1 can be constructed without using the screws 5, the construction is facilitated. Further, since the space between the building housing 7 and the wall panel 1 is reduced, the dead space is reduced and the unit room is enlarged.

  It is sectional drawing which shows the junction structure of the ceiling panel and wall panel which concern on this invention.   The partially cutaway perspective view of a ceiling panel.   The partially cutaway perspective view of a ceiling fixing piece.   It is sectional drawing which shows a prior art example.
