Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a panel supporting arcuate rim corresponding to a planned exterior arcuate surface when forming an arcuately curved exterior of a building.

The present invention provides a novel rim formation for an arcuate exterior that has a straight elongated material for the rim and can be attached to a predetermined position on a building while immediately forming an arcuate rim corresponding to a desired arcuate surface of the exterior. The present invention will be described in detail below with reference to drawings in which the arcuate exterior wall surface of an existing building is renovated.

In Figure 1, the arcuate outer wall surface of the existing building is
In this example, in a horizontal cross section, it consists of an outer wall part X that extends outward toward the outdoor side and an outer wall part Y that continuously retreats toward the indoor side, and the exterior support frame 1 is fixed along this outer wall surface.

The exterior support frame 1 is formed as follows. The primary support 2 of H-beam steel along the above outer wall surface...
are fixed perpendicularly to the frame B of the existing building at appropriate lateral intervals, and short spacing members 3 are installed on the outdoor side of each pillar 2 for the overhanging exterior wall X and for the receding exterior wall Y. Each of the long spacing members 3' is fixed horizontally, and a second support 4 made of H-beam steel is fixed vertically to the tip of each of these spacers 3..., 3'... to shape the second support 4 into a desired exterior arc shape. At the same time, each second support column 4 is connected horizontally with an appropriate vertical interval by secondary cross members 5. The secondary studs 6 are connected to each other, thereby forming the outdoor side surface into a polygonal shape when viewed from a plane, and the furring support member 7... located on the desired exterior arc-shaped surface is fixed to the outdoor side surface of such a support frame 1. do.

In this example, the above-mentioned rim supporting material 7 is made of a long piece of channel steel bent into an arc shape that matches the desired exterior arc-shaped surface, as shown in the third and fourth figures, and includes the above-mentioned secondary supports 4... and studs. Bracket 8 fixed to the outdoor side of 6...
..., the outdoor side arcuate surfaces are arranged on the desired exterior arcuate surface at vertical intervals corresponding to the rims of the exterior, which will be described later, and fixed horizontally. Numerals 9 and 10 are bolts and nuts for fixing the bracket 8, and bolts and nuts 11 and 12 are for fixing the furring support member 7 to the brackets 8.

The rim is a straight long piece of metal such as aluminum alloy 1
3, but the linear elongated material 13 is formed by the third
As shown in the figure, an engagement groove 15 with a substantially rectangular C-shape in cross section is provided on the indoor side surface of the plate-like base 14 over the entire length in the longitudinal direction, and a panel receiving part 16 with an L-shape in cross section is provided at the upper end of the base 14. A panel receiving portion 17 having a U-shaped cross section is provided at the lower end, and the installation thereof is as follows.

In advance, a suitable longitudinal position of the groove opening 15' of the engagement groove 15 in the long straight member 13 of the furrow is cut out, and the heads 19 of the required number of bolts 18 having square heads 19 are inserted into the engagement groove 15 from this cutout. Insert it so that it can slide freely. First, while holding the straight elongated material 13 horizontally, one end of the bolt 18 is set as the installation starting part P, and the bolt 18 is moved to that part.
, and screw the nut 20 thereon, thereby fastening the mounting start part P to the outdoor side surface of the support member 7.
Next, a bolt 18 is inserted into the support material 7 at an appropriate distance from the installation start part P to the other end, and a bolt 18 is inserted into the support material 7 at a portion slightly away from the outdoor side surface of the furring support material 7, and the nut 20 is screwed on. As a result, that part is drawn and fastened to the outdoor side surface of the support member 7, and the range of this part and the above-mentioned attachment start portion P is bent into an arc shape that matches the arcuate surface of the support member 7. Thereafter, in the same manner, as shown in the second figure, the bolts 18 are gradually tightened to the support member 7 at appropriate intervals toward the other end, thereby gradually tightening the bolts 18 to the support member 7. As it turns around,
and an arcuate rim 13' that matches the desired exterior arcuate surface.
to form. The attachment start portion P may be an intermediate portion of the elongated material 13. Incidentally, the connecting portions of the arcuate furring edges 13'... are connected to the adjacent furring edges 13', as shown in the fourth figure.
Separate plates 30, 30 are screwed to the left and right ends of 13', respectively, and a sealing material 31 is filled between the two side plates.

After forming the arcuate furring edges 13' horizontally at appropriate vertical intervals as described above, panels 21 with relatively small left and right widths are placed on the panel receiving parts 17 and 16 of the vertically adjacent arcuate furring edges 13' and 13'. Insert... The panel 21 is made of an extruded aluminum alloy in this example, and has an engagement groove 22 on one of its left and right ends, and an insertion portion 23 shaped to be able to engage with the engagement groove 22 on the other side.
, and a mounting plate 24 is extended across the insertion portion 23. One of such panels 21 is fitted into the arcuate edges 13', 13', and the mounting plate 24 is are fixed to the panel receivers 17, 16 with bolts 25, 26 and nuts 27, 28, and then another panel 21 is fitted into the arcuate edges 13', 13' next to the preceding panel, and then the preceding panel is removed. the engagement groove 22 is fitted into the insertion part 23 of the preceding panel, and fixed with bolts 25, 26 and nuts 27, 28,
Thereafter, panels 21 . . . are sequentially joined to the preceding panels in the same manner to form an arcuate exterior 29.

The furring support member 7 is not limited to the elongated one described above, but may be one in which a large number of furrow supporting pieces are arranged on a desired exterior arcuate surface and fixed to the brackets 8.

According to the method for forming the arcuate outer rim of the present invention,
Since it is possible to attach the straight long material for the rim to the building while bending it into an arc shape corresponding to the desired exterior arcuate surface, there is an elaborate process of separately bending the straight long material for the rim into an arc shape corresponding to the desired exterior arcuate surface. It is possible to omit the process and simplify the work process, and in addition, when bending a straight long material for the furring edge, it is easy to do this by gradual pulling and fixing. It also has the advantage of being able to
