Description

  The present invention relates to a building panel and a ceiling constructed using the building panel.

When a ceiling is constructed by a panel, a reinforcing member may be attached to the upper surface of the panel in order to prevent the ceiling from being bent. FIG. 3 of Japanese Utility Model Laid-Open No. 5-34221 describes a ceiling material in which an angle-shaped reinforcing member having a box-shaped cross section is bonded to the upper surface of the panel. This reinforcing member crosses the panel in the width direction.
Utility Kaihei 5-34221

  Just by attaching the reinforcing member as in the above-mentioned Japanese Utility Model Laid-open No. 5-34221, the strength of the connection between the reinforcing member and the ceiling material is insufficient, and for example, sufficient rigidity for mounting a heavy object such as a ventilation fan on the ceiling is ensured for a long time It is difficult to give to.

  An object of this invention is to provide the building panel which can attach a reinforcement member firmly, and the ceiling using this building panel.

  The building panel according to claim 1 is a building panel having a surface material and a heat insulating material attached to the back surface of the surface material. The shaft bar portion having a female screw hole is provided at one end of the shaft bar portion. A flanged anchor nut is provided, and the shaft rod portion of the flanged anchor nut is inserted into a hole penetrating the heat insulating material, and the flange is connected to the heat insulating material. It is arrange | positioned between the said surface materials.

  The building panel of claim 2 is characterized in that, in claim 1, the anchor nut with flange is made of synthetic resin.

  A building panel according to claim 3 is characterized in that, in claim 1 or 2, a plurality of the flanged anchor nuts are provided at predetermined intervals.

  A building panel according to claim 4 is the building panel according to claim 3, wherein a reinforcing member is superimposed on the opposite side of the surface material of the heat insulating material, and the reinforcing member is attached to the heat insulating material by a bolt screwed into the anchor nut with a flange. It is characterized by being attached.

  The ceiling according to claim 5 is a ceiling constructed by a building panel, and at least a part of the building panel is the building panel according to claim 3, and a heavy object is installed on the building panel. It is characterized by that.

  In the building panel of the present invention, a flanged anchor nut is provided, and a reinforcing member can be firmly attached to the anchor nut using a bolt. In addition, since the flange of this anchor nut with a flange is interposed between a heat insulating material and a surface material, the anchor nut with a flange is firmly integrated with the building panel. For this reason, when a reinforcing member is attached to the building panel to form a building panel with the reinforcing member, and a ceiling is constructed using the building panel with the reinforcing member, a ventilation fan and a hot air fan are placed on the building panel. Heavy equipment such as air conditioners can be installed.

  When the flanged anchor nut is made of synthetic resin, the building panel can be cut with a building material cutting tool such as a saw to obtain a desired size.

  If a plurality of anchor nuts with flanges are provided at predetermined intervals, the reinforcing member can be firmly attached to the building panel via the plurality of anchor nuts.

  Hereinafter, embodiments will be described with reference to the drawings. 1 is a perspective view of a building panel according to an embodiment, FIG. 2 is an enlarged view of a part of the building panel of FIG. 1, FIG. 3 is a sectional view taken along line III-III of FIG. FIG. 4 is a perspective view showing a state in which an L angle as a reinforcing member is attached to a building panel, FIG. 5 is a cross-sectional view taken along line VV of FIG. 4, and FIG. .

  The building panel 1 has a thin plate-like surface material 2 made of melamine, aluminum, steel plate or the like, and a heat insulating material 3 bonded to the back surface of the surface material with an adhesive. The heat insulating material 3 is made of a foamed synthetic resin board such as foamed styrene or foamed urethane. The building panel 1 is provided with a plurality of anchor nuts with flanges (hereinafter sometimes simply referred to as anchor nuts) 4 in the vertical and horizontal directions at regular intervals. The anchor nut 4 has a cylindrical shaft bar portion 4a provided with a female screw hole 4c, and a flange 4b provided at one end of the shaft bar portion 4a.

  The heat insulating material 3 is provided with a hole 3a (FIG. 3) having an inner diameter substantially the same as the outer diameter of the shaft rod portion 4a, and the shaft rod portion 4a is inserted into the hole 3a. The flange 4 b of the anchor nut 4 is interposed between the heat insulating material 3 and the surface material 2. In this embodiment, the heat insulating material 3 is provided with a shallow spot facing concave portion so that the surface of the heat insulating material 3 and the flange 4b are flush with each other, and the flange 4b is disposed in the concave portion.

  The front end surface of the shaft bar portion 4a is flush with the outer surface of the heat insulating material 3, but may be slightly retracted.

  An L angle 5 as a reinforcing member is overlaid on the heat insulating material 3, and the L angle 5 is fixed to the building panel 1 through bolts 6 and washers 7 screwed into the shaft bar portion 4 a of the anchor nut 4. ing. Note that the L angle 5 is a well-known one having two orthogonal leaves, and bolt insertion holes are formed at the same pitch as the anchor nut 4 on the surface overlapping the heat insulating material 3.

  The building panel 1 to which the L angle 5 is attached has extremely high bending strength and bending rigidity because the L angle 5 is firmly fixed via a plurality of anchor nuts 4 and bolts 6. Therefore, as shown in FIG. 6, the ceiling may bend even if a heavy object W such as a ventilation fan, a hot air fan for drying, or an air conditioner is placed on the ceiling constructed using the building panel 1 with the L angle 5. Absent. The ceiling panel may be the building panel 1 with the L angle 5, and only the panel on which the heavy object W is placed is the building panel 1 with the L angle 5. The panel may be constructed by 8).

  In this embodiment, the flanged anchor nut 4 is preferably integrally formed of synthetic resin. When the synthetic resin anchor nut is used in this way, when the building panel 1 is cut by the building material cutting tool in accordance with the site dimensions, it can be cut even if the cutting line overlaps the anchor nut. It is very convenient.

  In this embodiment, since the shaft bar portion 4a of the anchor nut 4 does not protrude from the heat insulating material 3, it is suitable when a plurality of building panels 1 are overlapped.

  In the present invention, a plurality of building panels 1 may be arranged in parallel, a reinforcing member such as an L angle may be arranged so as to straddle them, and bolted to be integrated.

  The building panel of the present invention can also be used to construct walls other than the ceiling. In the present invention, reinforcing members other than the L angle may be used.

It is a perspective view of the building panel which concerns on embodiment. It is a one part enlarged view of the building panel of FIG. It is the III-III sectional view taken on the line of FIG. It is a perspective view of the state where L angle as a reinforcing member was attached to the panel for construction. FIG. 5 is a sectional view taken along line VV in FIG. 4. It is a side view which shows the construction example of a ceiling.
