Description

  The present invention relates to a composite panel mounting structure.

  In buildings where the outer wall is composed of concrete-type outer wall panels such as lightweight cellular concrete (ALC), in order to improve heat insulation performance, a heat insulation panel made of a synthetic resin foam is attached to the back of the outer wall panel, and the composite panel is attached. May be configured.

  Composite panels are attached to hardware (ruler members) attached to a frame such as a beam of a building using through bolts or embedded bolts on the outer wall panel, but a heat insulating panel between the outer wall panel and the ruler member If an external force is applied to the outer wall panel or the ruler member, the heat insulation panel may be compressed by receiving a compressive force from the ruler member. In view of this, it has been considered that a heat insulating material is arranged on the beam portion having the ruler member so as to bypass the beam without adhering the heat insulating panel to the back surface of the outer wall panel. In this case, however, construction takes time and material costs increase. In addition, a portion where the heat insulating material is not continuous occurs, such as a portion where another beam is joined so as to be orthogonal to the beam, and the heat insulating property of the portion is deteriorated.

  In Patent Document 1, a heat insulating panel is disposed on the entire outer wall panel, a reinforcing member is provided in a bolt portion for fixing the outer wall panel, and a plate (a hook-shaped portion) of the reinforcing member is provided between the heat insulating panel and the mounting hardware. It is described that it arrange | positions. Thereby, crushing of a heat insulation panel can be suppressed.

  However, the reinforcing member cannot cope with a change in the thickness of the heat insulating panel, and a reinforcing member having a different sleeve length must be prepared in accordance with the change in the thickness of the heat insulating panel. Poor versatility. Moreover, since the position where the heat insulation panel is reinforced is limited to the vicinity of the bolt, the compression force acting on the position away from the bolt of the heat insulation panel cannot be dealt with.

  The present invention has been made in view of the above point, and provides a mounting structure for a composite panel that can cope with heat insulating panels having different thicknesses and can cope with compressive force acting on portions other than the vicinity of the bolts of the heat insulating panel. That is the purpose.

To achieve the above object, the present invention provides a composite panel mounting structure in which a composite panel consisting of an outer wall panel and a heat insulating panel covering the back surface of the outer wall panel is attached to a ruler member attached to a building shaft. A protective plate interposed between the heat insulating panel and the ruler member on the back surface thereof, and penetrates the heat insulating panel from the protective plate to the outer wall panel, and fixes the protective plate to the outer wall panel And the outer wall panel has an anchor plate fixed to the back surface of the outer wall panel by another screw different from the first screw, and the first screw is the anchor plate. It is the mounting structure of the composite panel which reaches and is fixed.

According to the present invention, since the protective plate is fixed to the outer wall panel using screws, even if an external force is applied to the outer wall panel, it is prevented that a compressive force is directly applied to the heat insulating panel between the protective plate and the outer wall panel. , The insulation panel is prevented from being crushed. Moreover, it can respond to the change of the thickness of the heat insulation panel by adjusting the screwing depth of the screw, and is highly versatile. Furthermore, since the attachment position of a protection board can be selected freely, it can respond to the compressive force which acts on various parts of a heat insulation panel. Moreover, even if it is an outer wall panel with comparatively low intensity | strength, a screw can be reliably fixed to an outer wall panel.

  The protective plate may have a claw portion that is pierced by the heat insulating panel. In such a case, displacement of the protective plate in the surface direction can be prevented.

  The composite panel mounting structure includes a bolt that penetrates the heat insulating panel from the outer wall panel and protrudes to the back surface side of the heat insulating panel, and is attached to the bolt on the back surface side of the heat insulating panel. There may be provided a backing plate for pressing the back side and a nut fastened to the bolt from the back side of the backing plate, and the protective plate may be provided between the backing plate and the heat insulating panel. In such a case, for example, even when the composite panel is pulled to the outside of the building by the negative pressure of the outside air and the backing plate is pulled to the outside accordingly, a protective plate is provided between the backing plate and the heat insulating panel. Therefore, the insulation panel can be prevented from being crushed.

  According to the present invention, heat insulation panels with different thicknesses can be accommodated, and the attachment position of the protective plate is not limited, so that versatility is improved and the production cost of the composite panel attachment structure can be reduced.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view of a longitudinal section showing an outline of a configuration of a composite panel mounting structure 1 according to the present embodiment.

  As shown in FIGS. 1 and 2, for example, the composite panel mounting structure 1 includes a floor beam 10 of a building frame, a ruler 11 as a ruler member, a composite panel 12, a protective plate 13, and a backing. It has a plate 14 and the like.

  The ruler 11 is a long member whose longitudinal section has an L shape, for example, and extends in the horizontal direction along the upper and lower floor beams 10. The ruler 11 has a horizontal piece 20 fixed to the floor beam 10 and a vertical piece 21 to which the composite panel 12 is fixed.

  The composite panel 12 includes an outer wall panel 30 and a heat insulating panel 31 that covers the entire back surface of the outer wall panel 30 (interior side surface, the same applies hereinafter). The outer wall panel 30 is made of lightweight cellular concrete, for example.

  The heat insulation panel 31 is obtained by bonding polyester nonwoven fabric to both surfaces of, for example, a phenol resin foam (phenol foam). The width dimension and the height dimension of the heat insulation panel 31 correspond to the width dimension and the height dimension of the outer wall panel 30 almost equally. The outer wall of the building is composed of composite panels 12 arranged vertically and horizontally.

  The protection plate 13 has, for example, a square shape, is provided on the back surface of the heat insulation panel 31, and a part thereof is disposed between the heat insulation panel 31 and the ruler 11. The protection plate 13 is formed of, for example, a steel plate having a higher strength than the heat insulating panel 31. For example, as shown in FIG. 3, the protection plate 13 is fixed to the outer wall panel 30 by a tapping screw 40 that penetrates the heat insulation panel 31 from the protection plate 13 and reaches the outer wall panel 30. The distance between the protective plate 13 and the ruler 11 is kept constant by the tapping screw 40. The tapping screws 40 are provided, for example, at four locations at the four corners of the protective plate 13.

  As shown in FIG. 1, for example, a bolt 50 is fixed to the outer wall panel 30 so as to penetrate the heat insulating panel 31 and the protection plate 13 from the inside of the outer wall panel 30 and protrude to the back surface side. The bolt 50 is provided at a position close to the ruler 11.

  The backing plate 14 is, for example, square and slightly bent. The backing plate 14 is inserted into the bolt 50 so that one part covers the back surface of the vertical piece 21 of the ruler 11 and the other part covers the back surface of the protection plate 13 and straddles the ruler 11 and the protection plate 13. ing. Therefore, the protective plate 13 is between the backing plate 14 and the heat insulating panel 31. A washer 51 and a nut 52 are attached to the back side of the backing plate 14 of the bolt 50. By tightening the nut 52, the composite panel 12 is drawn to the vertical piece 21 of the ruler 11 and fixed to the floor beam 10.

  According to the composite panel mounting structure 1 according to the present embodiment, even if an external force is applied to the outer wall panel 30 or the ruler 11, the outer wall panel 30 and the protection plate 13 are fixed by the tapping screws 40. A compressive force is not directly applied to the panel 31, and the heat insulating panel 31 is prevented from being crushed. Further, the tapping screw 40 can be penetrated even if the thickness of the heat insulating panel 31 changes within the range of the length of the tapping screw 40, and the outer wall panel 30 and the protection plate 13 can be fixed. Therefore, it can respond to the change of the thickness of the heat insulation panel 31 appropriately, and has versatility. Moreover, since the attachment position of the protection board 13 in the back surface of the heat insulation panel 31 can be selected freely, the protection board 13 can be installed in the position where a compressive force is easy to act.

  Further, since the protective plate 13 is provided between the backing plate 14 and the heat insulating panel 31, for example, the composite panel 12 is pulled to the outside of the building due to negative pressure of the outside air and the backing plate 14 is accordingly moved to the outside. Even if it is pulled, the crushing of the heat insulation panel 31 due to the pressure of the backing plate 14 can be prevented.

  In the composite panel mounting mechanism 1 described in the above embodiment, the outer wall panel 30 may have an anchor plate 60 fixed to the back surface thereof as shown in FIGS. In this case, the anchor plate 60 has a rectangular shape like the protection plate 13 and is fixed to the back surface of the outer wall panel 30 by screws 61. The anchor plate 60 is formed of, for example, a steel plate having higher strength than the main body of the outer wall panel 30. The tapping screw 40 penetrates the heat insulating panel 31 from the protective plate 13 to reach the anchor plate 60 and fixes the protective plate 13 to the anchor plate 60.

  In such a case, the tapping screw 40 can be reliably fixed to the outer wall panel 30 even if the strength of the outer wall panel 30 is relatively weak. In addition, the tapping screw 40 can be prevented from sinking into the outer wall panel 30 when the tapping screw 40 receives pressure.

  In the above embodiment, as shown in FIG. 6, the protection plate 13 may have a claw portion 70 inserted into the heat insulating panel 31. In such a case, for example, the claw portion 70 is formed in a pin shape with a sharp tip, and is stuck into the heat insulating panel 31 from a plurality of locations of the protective plate 13. By doing so, the lateral displacement of the protective plate 13 can be prevented.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the idea described in the claims, and these naturally belong to the technical scope of the present invention. It is understood.

  For example, the shape of the protection plate 13 may be another shape. The installation position of the protection plate 13 is not limited to the above example. The number and arrangement of the tapping screws 40 can be arbitrarily selected.

  INDUSTRIAL APPLICABILITY The present invention is useful when the composite panel mounting structure can cope with heat insulation panels having various thicknesses and can cope with the crushing of the heat insulation panels in portions other than the vicinity of the bolts.
