DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device for attaching an outer wall corner panel having an L-shaped cross section to a beam.

[0002]

2. Description of the Related Art In a building of a curtain wall structure in which an outer wall is constructed by arranging outer wall panels in parallel with a corner portion, at the time of installation, the outer wall panel made of a PC board (precast concrete board) or the like and a beam are used. Generally, a mounting bracket is interposed between the two. Conventionally, as described in Japanese Utility Model Publication No. 2-33532, a vertical portion of an L-shaped bracket having a vertical cross section is superimposed on the back surface of the outer wall panel, and the vertical portion is bolted to the rear surface of the panel. And the horizontal part of the bracket is fixed to the upper surface of the beam or the like.

[0003]

In this type of building having an outer wall panel structure, it is necessary to adjust the distance between the left and right vertical joints and the upper and lower horizontal joints between the outer wall panels when the building is installed on site. is there. In the above-mentioned conventional metal fittings, when the vertical adjustment is performed with the bolts on the back surface of the panel, the holes of the metal fittings into which the bolts are to be inserted must be long holes in the vertical direction. In the case of the above-mentioned conventional device, a height adjusting bolt is provided between the horizontal portion of the mounting bracket and the beam, and the height is adjusted at this portion. But
The structure is not designed to adjust the gap between the vertical joints on the left and right sides, and there is a disadvantage that such adjustment is extremely difficult.

SUMMARY OF THE INVENTION The present invention provides a device for supporting a corner panel of an outer wall under a beam, which eliminates the above-mentioned drawbacks of the prior art and allows easy adjustment of right and left and up and down during mounting. It is done for the purpose of.

[0005]

In order to solve the above-mentioned problems, according to the present invention, horizontal mounting is performed on the back surface of an L-shaped panel body constituting a corner of an outer wall, with each piece sandwiching the corner of the panel body. While fixing the plate, the upper end of the support post protruding above the horizontal support plate is fixed to the lower surface of the beam on the building frame side with bolts, and the tip of the support plate and the mounting plate below the support plate are also connected. Characterized by being fixed with bolts inserted vertically.

In the above, it is conceivable that the bolt hole for fixing the upper end of the support post to the beam is a loose hole.

[0007]

Before the bolts for fixing the L-shaped support plate to the beam are tightened, the support plate is rotated left and right around the bolt to adjust the joint gap in the left and right direction. The height of the entire panel is adjusted with the vertical bolts connecting the plate tip and the mounting plate.

Further, by making the bolt holes for fixing the support posts to the beams loose holes, it is possible to adjust the inside and outside of the corner panel.

[0009]

FIGS. 1 and 2 show a corner panel (5) for an outside corner of the present invention viewed from the back side. The back side of a concrete panel body (1) having an L-shaped cross section is shown in FIG.
At the upper end of each piece sandwiching the corner, a mounting plate (4) consisting of a vertical piece (2) and a horizontal piece (3) at the upper end of the vertical piece transfers the vertical piece (2) to the back of the panel body (1). It is attached and attached. A bolt hole (6) is previously formed in the horizontal piece (3) as shown in FIG.

Reference numeral (8) denotes an L-shaped horizontal support plate (8) made of a metal plate, and a bolt hole (9) is formed at each end thereof (see FIG. 4). The tip of the bolt (11) inserted from below into the bolt hole (6) at the tip of the mounting plate (4) is inserted into the bolt hole (9) at the tip of the support plate (8) and screwed into the upper part. The mounting plate (4) is connected with the nut (12) thus formed, and the corner panel (5) is supported in a suspended manner via the mounting plate (4).

The bent portion of the support plate (8) is provided with a joining plate (10) at the upper end, and the support plate (8)
A support post (7) having an L-shaped horizontal cross section bent in the opposite direction is integrally fixed so as to protrude upward. A bolt hole (14) which is a loose hole is formed in the center of the joining plate (10).

The support plate (8) and the support post (7) are transported to the site in a state where the support post (7) is mounted on the mounting plate (4) in advance. At this time, a U-shaped spacer (13) as viewed from the side is fitted between the mounting plate (4) and the support plate (8) so as to fit to the bolt.

The corner panel carried in a state in which the support plate (8) and the support post (7) are integrally attached as described above is connected to the joint plate (10) at the upper end of the support post (7) by the beam at the corner. At the tip of the lower flange (16) of (15), make contact with the lower surface of the lower flange (16), and align the bolt holes (14) with the bolt holes (17) of the beam (15). Will be installed. A nut (19) is screwed into the end of the bolt (18) inserted into the bolt hole (14) (17) from above, and fixed. Before tightening the nut (19), Within the gap between the bolt hole (14) and the bolt (18), the support plate (8) is moved in and out to adjust the inside and outside, and the left and right are centered on the bolt (18). When the horizontal position is determined by rotating or moving to adjust the gap in the left-right direction, it is formally tightened and fixed.

Next, the spacer (13) interposed between the support plate (8) and the mounting plate (4) is removed, and the nut (12) of the bolt (11) inserted into the tip is rotated. Then, the height of the entire corner panel (5) is adjusted, and the mounting operation is completed.

[0015]

As described above, according to the present invention, the joint gap in the left-right direction can be easily adjusted by rotating the support plate or the like. On the other hand, the nut is rotated by the bolt at the tip of the support plate. Accordingly, the height of the panel can be adjusted, and therefore, there is an effect that an outer wall with uniform joint gaps can be constructed by a simple operation.

Further, according to the invention of claim 2 of the present application, since the bolt holes for fixing the support posts are loose holes, the inside and outside of the panel can be easily adjusted in and out of the range of the loose holes. .
