Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a device for attaching exterior panels such as PC boards to a steel frame.

(Prior art) Generally, when an exterior panel such as a PC board is attached to a steel frame integrally with the steel frame, the deformation capacity of the steel frame is greater than that of the exterior panel. It may become unable to follow the deformation of the building frame and cause brittle fracture. Therefore, in recent buildings of this type, when attaching exterior panels to the frame, separate fasteners are used for the attachment parts provided on the upper and lower panels, respectively.
The exterior panels were installed so that they could follow the deformation of the steel frame.

(Problem to be solved by the invention) However, in the conventional device, the upper and lower exterior panels are attached using separate fasteners, which not only significantly increases the number of parts and construction man-hours, but also has the drawback of increasing the time and effort required to install the exterior panels. It was hot.

This invention is capable of following deformation even when subjected to external forces such as earthquakes, and also solves the problems of the conventional art.

(Means for Solving the Problems) This invention has bolts for adjusting the height of panel mounting, holes for inserting the bolts for panel mounting in the vertical part, and bolts for adjusting the mounting height in the horizontal part. A metal fitting having an L-shaped cross section with an insertion hole and a nut fixed to the lower part thereof, a rectangular fastener having vertically long elongated holes formed at both upper and lower ends, and a fastener fixed to a beam and fixed to the fastener. A mounting device having a hardware having an L-shaped cross section,
At the lower end of the exterior panel, the L-shaped cross-sectional metal fitting having the panel mounting hole and the nut faces the indoor side, and the panel mounting bolt is inserted into the hole in the vertical part and the elongated hole at the upper end of the fastener. The panel is attached by being inserted and tightened, and the panel is attached by screwing the height adjustment bolt into the nut of the horizontal section of the L-shaped fitting having the hole for bolt attachment. The exterior panel is characterized in that the mounting height is adjusted, and further, the upper end of the exterior panel is fixed with panel mounting bolts through the elongated holes at the lower end of the fastener to which the upper panel is fixed. It is a mounting device.

(Example) Hereinafter, this invention will be explained using an example illustrating the invention. In this example, as shown in FIGS. 1 and 2, a metal fitting 5 having a substantially L-shaped cross section is attached to a beam steel frame 1, which is the steel frame of a building, and is fixed to this metal fitting 5, as shown in FIG. As can be seen, the fastener 8 is constructed as follows using a strip-shaped fastener 8 with vertically long holes 6 and 7 formed at both upper and lower ends. That is, the metal fitting 5 having a substantially L-shaped cross section is attached to the upper flange 1a of the beam steel frame 1 by welding or bolting, and the rectangular fastener 8 is attached to the surface of the rising edge 5a of the metal fitting 5 having a substantially L-shaped cross section. It is attached by welding or bolting to the side (in this example it is welded).

In addition, the lower end of the exterior panel is provided with another approximately L-shaped cross section metal fitting 1 inside the upper end of the rectangular fastener 8.
3, and pass the panel mounting bolt 9 through the hole in the vertical part of the metal fitting 13, which has a substantially L-shaped cross section, through the anchor nut 10 etc. buried in the lower end of the exterior panels 3, 4 in advance. It is fixed by screwing into the back of the long hole 6 of the fastener 8. Furthermore, the horizontal portion 1 of this metal fitting 13 having a substantially L-shaped cross section
Attach bolt 1 for adjusting the panel height to 3a from above.
For example, the horizontal part 5 of a metal fitting 5 having a substantially L-shaped cross section is fixed to a rectangular fastener 8.
A part, preferably most, of the weight of the upper and lower exterior panels 3 and 4 is transferred to the beam steel frame through the metal fittings 13 having a substantially L-shaped cross section and the bolts 14 for height adjustment. It is adjusted and screwed in so that the transmission is transmitted to the 1st part.

For the upper ends of the exterior panels 3 and 4, screw the panel mounting bolts 9 into the anchor nuts 10 etc. buried in the upper ends of the exterior panels 3 and 4 in advance from the backs of the long holes 6 of the rectangular fasteners 8. It is fixed by.

Further, the metal fitting 5 having an L-shaped cross section may be made of angle iron, for example, and may be a long piece continuous in the longitudinal direction of the beam steel frame 1 or a piece-like object. The upper and lower elongated holes 6, 7 of the rectangular fastener 8 may be formed as shown in FIG. 3, or may be formed as continuous elongated holes 11 as shown in FIG. Alternatively, as shown in FIG. 5, the upper end of the elongated hole may be opened to form a notch 12. This fifth
When using the rectangular fastener 8 shown in the figure, when fixing the lower ends of the upper and lower exterior panels 3 and 4, the panel mounting bolts 9 are temporarily tightened to the anchor nuts 10 in advance, and the Immediately after the fixed panel mounting bolt 9 is installed so as to be fitted into the notch 12, the panel mounting bolt 9 can be fully tightened, which further simplifies the construction.

The exterior panels 3 and 4 are provided with strip-shaped fasteners 8 at least at one lower end and at least one upper end.
Alternatively, as shown in FIG. 6, strip-shaped fasteners 8 may be used at two locations each on the upper and lower sides. Further, as shown in FIG. 2, reinforcing ribs 16, 16 may be welded to both sides of the metal fitting 13, which has a substantially L-shaped cross section, if necessary.

(Function) As described above, in this invention, the metal fitting 13 having a substantially L-shaped cross section is installed by screwing the panel mounting bolt 9 into the anchor nut 10 of the upper and lower exterior panels 3, 4 from the back of the vertical portion 13b. Exterior panels 3, 4
The metal fitting 1 is fixed to the lower end of the
A height adjustment bolt 14 is screwed into a nut 15 welded and fixed to the lower surface of the horizontal portion 13a of the exterior panel 3, thereby adjusting the mounting height of the exterior panel. is configured to be transmitted to the beam steel frame 1, so that the strip-shaped fastener 8 is only exposed to external force during an earthquake in the gap between the long hole at the top of the strip-shaped fastener 8 and the bolt 9. Similarly, at the upper ends of the exterior panels 3 and 4, the upper ends of the exterior panels 3 and 4 can be moved by the gap between the long hole at the bottom of the rectangular fastener 8 and the bolt 9. becomes. Therefore, as shown in FIG. 6, when an external force such as an earthquake is applied, the exterior panel can lock and follow the deformation of the steel frame.

(Effect of the invention) This invention consists of a metal fitting 5 with a substantially L-shaped cross section fixed to the building frame 1, and a rectangular shape with vertically long holes formed at both upper and lower ends, which is attached and fixed to the metal fitting 5. A fastener is used, and the upper and lower exterior panels are inserted into the long hole from the back of the panel mounting bolt 9.
Since it is attached by screwing in, one strip-shaped fastener can be used to attach two upper and lower exterior panels, reducing the total number of fasteners and the number of construction steps, and as a result, the number of exterior panels can be reduced. can be installed extremely easily. At the same time, even if the frame is deformed by external force such as during an earthquake, the exterior panel can be effectively locked to follow the deformation of the frame, thereby preventing destruction of the exterior panel due to external force.
