Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a joining device for a honeycomb panel provided with an embedded metal fitting for mounting a fixing bolt used in a curtain wall or the like.

[0002]

[Prior art]

 Honeycomb panels are widely used for carten walls, etc. because they have excellent sound absorption, heat insulation, energy absorption, etc., but when they are used for curtain walls, etc., a large number of honeycomb panels are joined together to form a large honeycomb. The panel is fixed to the body with fixing bolts.

As is well known, one honeycomb panel has an upper surface plate brazed to the upper surface of a honeycomb core and a lower surface plate brazed to the lower surface thereof, and a U-shaped frame member is fitted between the upper surface plate and the lower surface plate at the periphery thereof. And the frame members are welded to the upper and lower plates. In order to join such honeycomb panels, for example, as shown in FIG. 5, an embedded metal article 22 having a predetermined length (for example, 100 mm to 200 mm) is provided on the frame material 21 of one honeycomb panel 20 at predetermined intervals. After arranging them, the embedded metal 22 is welded 23 to the frame member 21 over the entire length, and then the other honeycomb panels 20 and 20 are butted as shown in the figure, and the butted upper and lower plates are welded to each other.

When the large-sized honeycomb panel thus joined is attached to the frame 14, the embedded metal 22 is tapped, and the fixing bolt 13 is screwed onto the tapped metal 22 to attach the bonded portion of the honeycomb panel 20 to the frame 14. It was fixed to.

[0005]

[Problems to be solved by the device]

 The operation of welding 23 the embedded hardware 22 to the frame member 21 can be performed on only one side. Since only one side of the frame material 21 is welded, the contraction of the welded portion 23 distorts and the other side of the embedded metal material floats upward, and a gap 24 is generated between the lower surface of the embedded metal material 22 and the frame material 21. . If there is a gap 24 here, it becomes difficult to perform tap processing for attaching a fixing bolt or insertion work of a helisert at a construction site such as a curtain wall. Because of the gap 24, the pitches of the lower surface plate 6, the frame member 21, and the female screw of the embedded member 22 are deviated, which makes it difficult to screw the fixing bolt.

Further, when a gap 24 is generated between the embedded metal product 22 and the frame member 21, the weld metal 23 welds only the load, but the honeycomb used in a building such as a curtain wall. Since the panel 20 is repeatedly subjected to an alternating load such as wind pressure, there is a possibility that it will be a problem in strength.

[0007] Therefore, the present invention solves such a problem and provides a honeycomb panel in which tapping of embedded metal and screwing and tightening of a fixing bolt are easily and surely performed, and a large honeycomb panel can be firmly fixed to a frame. It is intended to provide a joining device.

[0008]

And the protruding piece has an embedded metal object formed in a wedge shape, so that the embedded metal object is inserted between the lower plate piece and the protruding piece to face each other. When the materials are butted, the projection piece presses one surface of the wedge-shaped portion of the embedded metal article, and the embedded metal article is sandwiched and fitted to the lower plate piece and the projection piece. .

In the honeycomb panel joining apparatus of the second invention, an upper plate piece is provided on an upper part of a side wall, a lower plate piece is provided on a lower part, and a projecting piece is provided in the middle of the side wall. By having a frame member having a substantially E-shaped cross-section formed by inclining in a direction away from the piece, and an embedded metal article inserted between the lower plate piece and the protruding piece that face each other, When the embedded metal object is inserted between the lower plate piece and the protruding piece, and the opposing frame members are butted against each other, the embedded metal object presses the lower surface of the protruding piece, and the embedded metal object Is sandwiched between the lower plate piece and the projection piece.
