TECHNICAL FIELD The present invention relates to, for example, an outer wall material,
The present invention relates to a honeycomb panel used as a roofing material or an interior material, and more particularly to a honeycomb panel having a constant inclination angle and different thicknesses, and a method for manufacturing the same.

[0002]

2. Description of the Related Art In general, aluminum honeycomb panels are widely used for exterior wall materials, roof materials, interiors, and the like. As this honeycomb panel, as shown in FIG.
It is known that a frame member b is arranged outside a pair of surface plates a and a, and a core c having a honeycomb structure is arranged inside, and these are integrated by brazing in a high-temperature atmosphere. As the core, for example, as shown in FIGS. 7 and 8, a large number of strips d made of aluminum are bonded in a staggered manner to form a core material, and the core material is pulled in a direction perpendicular to the bonding surface. A hexagonal cell formed by bonding a number of hexagonal cylindrical cells to each other and, as shown in FIG. 9, aluminum alloy bent plates e which have been bent in a trapezoidal corrugated shape in advance. And are used. The strip d and the bent plate e are provided with holes for air release, and when brazing, the internal air is released to the outside through the air release holes, so that the air during brazing is released. Ripple deformation of the surface plate due to expansion, thermal expansion of aluminum itself, and rippling of the surface plate due to thermal contraction are prevented (Japanese Patent Laid-Open No. Sho 62-214).
No. 839).

[0003]

By the way, the thickness of the honeycomb panel is changed according to various specifications, or a honeycomb panel having an inclined angle (for example, a thin panel at one end in the longitudinal direction and a thick panel at the other end) is formed. The following method has been considered as a method for performing this. (1) The core is cut in accordance with the thickness or the inclination angle of the honeycomb panel, and the core is interposed between a pair of surface plates. (2) After cutting the belt-like body according to the inclination angle of the honeycomb panel in advance, brazing to each other to form a core material,
The core material is expanded (deployed) into a core.

(4) The trapezoidal corrugated sheet is cut in advance according to the inclination angle of the honeycomb panel, and the trapezoidal corrugated sheets are brazed together to form a core, and the core is interposed between the pair of surface plates.

However, when adopting the above method,
In general, not only the above-mentioned band-shaped body and the above-mentioned bent plate but also a thin plate are easily deformed by cutting, and the cut surface is severely roughened. For this reason, the contact and sitting of the core with the surface plate are significantly deteriorated, and a gap for brazing is widened, so that brazing failure is likely to occur. Therefore, it is not suitable as a method for processing a strip or bent plate made of a thin aluminum plate which is easily sticky and has low strength, and has not been adopted.

Further, in the method of expanding the core material by pulling the core material in the orthogonal direction, it is extremely difficult to expand the belt-like body in accordance with the inclination angle of the honeycomb panel, and a certain accuracy is obtained.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

First Embodiment FIG. 1 shows an embodiment in which a honeycomb panel is formed using an elastic aluminum winding body as a core material.

As shown in the figure, first, an aluminum clad material whose outer surface is coated with a brazing material (such as JIS A4045) is cut into a predetermined length, and the cut strip 1 is cut.
A hole 2 or a slit to be used as an air vent is formed at an appropriate place, and a pair of surface plates 3, 3 made of, for example, aluminum, and a cross section made of, for example, aluminum having an inclined surface corresponding to the inclination angle of the panel A rectangular frame 4 is prepared. In this case, as shown in FIG. 2, the frame member 4 is composed of two types of end frame members 4 arranged at both ends in the inclination direction of the panel.
a, 4b and a pair of side frame members 4 in the tank in the direction of inclination of the panel.
c and 4c are prepared. That is, an end frame material 4a having a low height, an end frame material 4b having a high height, and a side frame material 4c having a sloped surface 4d along the inclination angle are prepared. The side frame member 4c may be a frame member 4e having the same height without the slope surface 4d, and a spacer 4f may be interposed in a gap between the side frame member 4c and the surface plate 3 (see an imaginary line in FIG. 2). .

Then, the above-mentioned band-shaped body 1 is wound at least one turn around at least one axis to form a cylindrical core material (elastic body) 5.
Is formed, and this core material 5 is
For example, the frame members 4 are arranged in a staggered manner and adjacent to each other, and the frame members 4 are arranged outside the core members 5 so as to be in contact with the outer core members 5. Of course, the arrangement of the core material 5 is not limited to the above example.
May be arranged adjacent to each other. In this case, each core member 5 is placed so that the outer peripheral surface of the core member 5 is in contact with the surface plate 3.

After placing the core member 5 and the frame member 4 (specifically, 4a to 4c or 4a, 4b, 4e, 4f (hereinafter, represented by reference numeral "4")) on the pair of surface plates 3 , The other surface plate 3 is placed from above, and then both surface plates 3 are sandwiched between works (not shown) and pressed against the respective core members 5 via the surface plates 3. That is, the distance between the pair of surface plates 3 is adjusted by elastically deforming each core member 5 radially inward.

When a predetermined inclination angle is set between the surface plates 3 and 3, the distance between one end in the longitudinal direction or the width direction of the surface plate is the narrowest and the distance between the other ends is the widest. ,
In addition, the intervals between the surface plates 3 and 3 are set so as to gradually increase from one end to the other end.

Thereafter, while maintaining the above-mentioned interval setting, the whole is heated to a brazing material melting temperature for a predetermined time in a high-temperature atmosphere such as a heating furnace to melt the brazing material. By this treatment, the molten brazing material is cut by the surface tension into the cuts of the core material 5, the joining surface between the core material 5 and the frame material 4, and the core material 5 and the surface plate 3.

Therefore, if the brazing material is cooled and solidified after the melting process, the spiral surfaces of the core materials 5a, the core materials 5a, the core material 5a and the surface plate 3, and the core material 5a and the frame material 4 will have no gap. A large number of core members 5a can form a group of cores, and at the same time, a honeycomb panel 6a having a fixed inclination angle can be formed.

Therefore, even with the honeycomb panel 6a according to the second embodiment, it is possible to provide a highly reliable and inexpensive honeycomb panel free from brazing defects due to cutting of the core material and assembly accuracy defects.

In the second embodiment, the entire length of the honeycomb panel 6a is long and the difference between the one end and the other end of the pair of surface plates is large due to the setting of the inclination angle. If this occurs, this problem can be solved by arranging core materials having different numbers of stages. For example, a core material 5a with a small number of steps is arranged on one end side, and a core material 5a with a large number of steps is arranged on the other end, and the gap difference is absorbed by the number of steps of the core material 5a. A plurality of different core members 5a are arranged to absorb a difference in interval. Of course, the core material 5 described in the first embodiment is used for a portion where the interval between the pair of surface plates 3 and 3 is narrow, and the core material 5a described in the second embodiment is used for a portion where the interval is large.
