Description

[Detailed Description of the Invention] This invention relates to an arcuate exterior structure for remodeling the arcuate outer wall of an existing building.

Generally, the arcuate exterior walls of existing buildings have many irregularities, and the conventional method of renovating such existing exterior walls has been to directly attach new panels along the irregularities of the existing exterior walls. but,
Due to the complexity of the walls, construction took a long time, and there were drawbacks such as insufficient watertightness.

The proposed arc-shaped exterior structure for renovating the exterior wall of an existing building eliminates the conventional drawbacks, and will be described in detail below with reference to the drawings.

As an example, the arcuate outer wall surface of the existing building in Figure 1 is
In horizontal cross section, it has an uneven arcuate surface consisting of an outer wall part X extending toward the outdoor side and an outer wall part Y continuously receding toward the indoor side, and the exterior support frame 1 is fixed along this outer wall surface.

The exterior support frame 1 has the following configuration. In Fig. 1, H-shaped steel primary supports 2 are fixed perpendicularly to the existing building frame 2 along the exterior wall surface at appropriate lateral intervals, and attached to the outdoor side of each support 2. , Short spacing members 3... are fixed horizontally on the overhanging outer wall portion X, and long spacing members 3'... are fixed horizontally on the receding outer wall portion Y, and H-shaped steels are attached to the tips of these spacing members 3..., 3'... The second pillars 4 are fixed vertically, and the second pillars 4 are arranged at positions along the desired exterior arcuate surface, and secondary cross members 5 are installed between the second pillars 4 as appropriate. They are connected horizontally at vertical intervals, and secondary studs 6 of H-beam steel are connected between these horizontal members 5, respectively, thereby forming the outdoor side surface into a polygonal shape when viewed from a plane, and providing support like this. Exterior mounting members 7 are fixed to the outdoor side surface of the frame 1 so as to be positioned on a desired desired exterior arcuate surface.

In this example, the exterior mounting material 7 is made by bending a long piece of channel steel into an arc shape that matches the desired exterior arcuate surface, as shown in the second and third figures. Bracket 8 fixed to the outdoor side of...
The mounting members 7 are fixed horizontally at vertical intervals corresponding to the rims of the exterior arcuate surfaces, which will be described later, and arcuate exterior members 29 are attached to the outdoor side surfaces of the mounting members 7. Numerals 9 and 10 are bolts and nuts for fixing the bracket 8, and 11 and 12 are bolts and nuts for fixing the mounting member 7 to the bracket 8.

The arcuate exterior material 29 is made by supporting the panels 21 on the arcuate rims 13 that are positioned horizontally at appropriate vertical intervals, but in this example, a straight long material for the rim made of metal such as aluminum alloy is used. As shown in the second figure, the linear elongated material is provided with an engagement groove 15 having a substantially rectangular C-shaped cross section over the entire length in the longitudinal direction on the indoor side surface of the plate-like base 14, and on the base 14. A panel receiving portion 16 having an L-shaped cross section and a panel receiving portion 17 having a U-shaped cross section are provided at the lower end, respectively.
One end or the middle part of this straight long material for the body edge is used as the installation start part, and the bolt 18 with the head 19 inserted into the engagement groove 15 is passed through the exterior mounting material 7 and the nut 20 is screwed into that part. Then, tighten the part from the above mounting starting part to the other end or both ends at an appropriate distance to the mounting material 7 in the same manner as above, and then similarly tighten the other end or both ends to the mounting material 7. Bolts 18 are gradually tightened to the mounting member 7 at appropriate intervals to form a straight elongated member on the arc-shaped body rim 13.

The panels 21 are relatively small in width from side to side, and in this example are rectangular plates made of extruded aluminum.
As shown in the third figure, a locking groove 22 is provided on one of the left and right ends.
and an insertion portion 23 having a shape that can be engaged with the locking groove 22 on the other side, and the insertion portion 2
A mounting plate 24 is extended on three sides, and one of these panels 21 is attached to the vertically adjacent arcuate edge 1.
Fit the mounting plate 24 into the panel receivers 17 and 16 of 3 and 13, and tighten the bolts 25 and 26 and nuts 27 and
28 to the panel receivers 17 and 16, and then, after fitting another panel 21 in the same way, press it against the preceding panel and fitting its locking groove 22 into the insertion part 23 of the preceding panel. Similarly, panel 2
1... are fitted to form an arc-shaped exterior material 29.

In addition, the connection part of the furring 13... is made by screwing the side plates 30, 30 to the left and right ends of the adjacent body edges 13, 13, respectively, as shown in the third diagram, and filling the space between the two side plates with a sealing material 31. It maintains watertightness.

The above-mentioned exterior mounting material 7 is not limited to the long one shown above, but may be one in which a large number of exterior mounting pieces are arranged at appropriate intervals on the planned exterior arcuate surface and fixed to the brackets 8. It may be hot.

According to the arc-shaped exterior structure of this invention for renovating the exterior walls of existing buildings, the arc-shaped exterior walls with many unevenness of the existing buildings are uniformly covered with arc-shaped exterior materials, so the structure is extremely simple, and it is possible to renovate the existing buildings. It is possible to significantly shorten the construction period,
Moreover, it also has the advantage of being able to ensure sufficient watertightness.
