Description

  The present invention relates to a frame that can be used for an outer wall panel, an outer wall panel using the frame, and an outer wall structure in which the outer wall panel is fixed to a structural frame of a building.

  Patent Document 1 discloses an outer wall structure in which an outer wall panel is disposed inside a structural frame made of column beams, and the frame of the outer wall panel is fixed to the column beams.

Japanese Patent Laid-Open No. 10-072886

  In the outer wall structure of Patent Document 1, when the housing is deformed between layers, a force is applied to the outer wall panel, and the outer wall panel may be damaged in some cases.

  Therefore, it is conceivable to adopt a curtain wall type outer wall structure in which an outer wall panel is fixed to the outdoor side of a structural frame composed of column beams.

  However, in such an outer wall structure, the outer wall panel needs to appropriately receive wind pressure and transmit force to the structural frame. However, the method of fixing the outer wall panel to the housing is often screwed to the frame surface facing the housing because of the fit. At this time, a force is applied in the out-of-plane direction of the plate having a small proof stress. For this reason, solutions such as increasing the number of fixing points to reduce the burden per point or increasing the frame cross section are conceivable.

  In view of the above circumstances, the present invention provides an outer wall panel configured by using the frame so that wind pressure can be appropriately received without increasing the number of fixing points and minimizing the cross section of the frame, and the outer wall panel. It is an object of the present invention to provide an outer wall structure of a curtain wall type that uses the above.

  In order to solve the above problems, a frame of the present invention includes a vertical frame having a web and a flange, a horizontal frame having a web and a flange, and an L-shaped member having a first surface portion and a second surface portion in an L shape. The vertical frame and the horizontal frame are joined to form a frame shape, and the L-shaped member is mounted inside the corner of the frame shape, and the first surface portion of the L-shaped member Is positioned on the web of the vertical frame or the horizontal frame, and the second surface portion of the L-shaped member is positioned at the flange of the vertical frame and the horizontal frame.

  If it is said structure, since the L-shaped member which has a 1st surface part and a 2nd surface part in L shape is mounted | worn inside the frame-shaped corner | angular part by the said vertical frame and the said horizontal frame, it is thick. Rigidity is increased while achieving weight reduction without making it too thick. Further, when a force is applied to the flange in a direction perpendicular to the surface, the force is transmitted from the second surface portion of the L-shaped member to the web via the first surface portion. Therefore, the force is stably received in the in-plane direction of the web.

  The L-shaped member is attached to the upper corner portion of the frame, and another L-shaped member is disposed at the lower corner portion of the frame, with the first surface portion and the second surface portion being the vertical frame and the horizontal frame. The webs may be provided respectively on the webs. According to this, for example, when the bolt is vertically inserted into the web which is the lower surface of the horizontal frame and the frame is arranged on the foundation, the weight of the frame is received using the other L-shaped member. Is possible.

  The L-shaped member may be attached by a screw with a head screwed from the outer surface side of the web of the vertical frame. According to this, when the frames are arranged side by side with the webs of the vertical frames arranged on the back, an interval (joint) corresponding to twice the head height of the head screw is provided between the vertical frames of the frames. Can be secured.

  The outer wall panel of the present invention is characterized in that an outer wall plate is fixed to any one of the above-mentioned frames. According to this, the above various effects can be enjoyed as an outer wall panel. Further, even if a force for deforming the outer wall panel is applied to the outer wall panel during an earthquake, the right angle of the corner of the outer wall panel can be maintained and damage to the outer wall plate can be prevented.

  The outer wall panel may have a bolt portion protruding from a flange on the back side of the frame. According to this, when wind pressure is applied to the flange on the back side in a direction perpendicular to the flange, the wind pressure is transmitted from the second surface portion of the L-shaped member to the web via the first surface portion. The Therefore, the wind pressure is stably received in the in-plane direction of the web.

  Moreover, the outer wall structure of the present invention is a curtain wall type outer wall structure that is fixed to the outdoor side of a structural housing in which the outer wall panel is formed of a column beam, and a part of the outer wall panel is formed on the structural housing. It is characterized by being fixed to the structural housing using the bolt part that has passed through the insertion hole of the provided mounting member. According to this, when a wind pressure is applied to a part of the outer wall panel in a direction orthogonal to the surface of the flange on the back side, the wind pressure is transmitted to the structural housing via the bolt portion. . And since the said wind pressure is transmitted to the said web via the said 1st surface part from the said 2nd surface part of the said L-shaped member, it is stably received in the surface direction of this web.

  According to the present invention, it is possible to increase the rigidity while realizing a light weight without making the frame thick. Moreover, it becomes possible to receive a wind pressure appropriately as an outer wall panel. And there exists an effect that the outer wall structure of a curtain wall type is realizable using the said outer wall panel.
