DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a honeycomb panel, and more particularly, to a honeycomb panel having a hollow core material interposed between a pair of surface plates.

[0002]

2. Description of the Related Art In general, honeycomb panels are widely used for outer wall materials, roof materials, interior materials and the like. As this honeycomb panel, a pair of surface plates a, a made of a rectangular aluminum alloy as shown in FIG.
a frame member b formed of an extruded aluminum alloy material and the like, and a honeycomb core member interposed in a space formed by both face plates a and a and the frame material b There is known a structure in which c is integrally formed by brazing.

In the honeycomb panel constructed as described above, the honeycomb core material c is formed by bonding a plurality of strips d made of an aluminum alloy in a staggered manner as shown in FIGS. 9 and 10, for example. A hexagonal cylindrical hollow body that is pulled in a direction perpendicular to the surface and an aluminum alloy bent plate e that has been previously bent into a trapezoidal wave shape are bonded as shown in FIG. A hollow body is used.

[0004]

However, in the case of manufacturing honeycomb panels having different sizes and shapes using the honeycomb core material c formed integrally as described above, the honeycomb core material c is not used. It is necessary to cut into a predetermined shape, so that not only a lot of labor and time are required for cutting, but also a problem that the shape of the honeycomb core material c is damaged, and the strength, heat insulation and sound insulation of the honeycomb panel are reduced. There is.

Also, a honeycomb core material c using a bent plate e
However, there is a problem that a hollow body having a circular or triangular shape cannot be formed. Furthermore, when making a honeycomb panel using this kind of honeycomb core material c,
Since it is necessary to prepare a honeycomb core material c which is cut in accordance with the space formed by both surface plates a and the frame material b, it takes time and effort to set the honeycomb core material, resulting in poor workability. is there.

Further, when a bent panel having a curved surface is formed on a surface plate, there is a problem that the bending direction of the core material c is constant in two dimensions, and it is difficult to form a spherical three-dimensional bent panel. Was. When forming a bent panel, FIG.
As shown in FIG. 2, there is a problem that a gap f is formed between the core material c and the surface plate a, so that the gap f must be filled with a filling material. Further, when the panel itself needs to have a partial strength, a notch for inserting a honeycomb panel having a predetermined strength is required, and thus there is a problem that the formability is poor.

Furthermore, in order to form this type of honeycomb panel, brazing is performed at a high temperature, for example, 640 to 650 ° C. in a heat treatment furnace, so that the air in the honeycomb core material expands and returns to room temperature after forming. Conversely, since the air in the honeycomb core material shrinks, deformation may occur due to a change in air pressure due to a temperature change. In order to prevent this, it is conceivable to provide an air vent hole in the honeycomb core material. However, since the conventional honeycomb core material has a hexagonal shape, the position where the air vent hole is provided is limited. That is, since the air vent hole is provided at either the joint portion of the honeycomb core material or the hexagonal side portion, the directionality is limited, air cannot be released smoothly, and pressure is adjusted in a short time. Can not do. Therefore, there is a problem that it is difficult to eliminate the deformation of the surface plate.

The present invention has been made in view of the above circumstances, and can easily dispose a core material in a space formed between surface plates, regardless of the shape of a panel, and has strength and heat insulating properties. It is an object of the present invention to provide a honeycomb panel capable of improving sound insulation and formability.

In this case, the number and arrangement of the air vent holes may be arbitrary as long as the plurality of air vent holes are deviated from the axial direction of the cylindrical single body. For example, one or more rows are arranged in a direction inclined with respect to the axis of the cylindrical single body. Alternatively, the inclination directions may be arranged in an intersecting manner, and further, for example, a staggered or random arrangement may be used.

A second honeycomb panel according to the present invention includes a pair of aluminum alloy surface plates, and a core material interposed in a space between the surface plates, wherein the core materials are independent of each other. was formed by the large number of aluminum alloy cylindrical single contact with each other and formed by a set group, to form a groove on the side surface of the tubular alone, the air vent hole provided in the recessed groove, the surface plate and Of the cylindrical simple substance

The cylindrical simple bodies touch each other
By forming a group consisting of the above, a tubular single body can be easily interposed in the above space, and also at the peripheral portion, a hollow portion similar to the hollow portion partitioned at the inner portion is formed. In addition, even when a curved surface is provided on the surface plate, the cylindrical body can be deformed in accordance with the bending deformation of the surface plate. Accordingly, it is possible to easily form not only a flat honeycomb panel but also a curved honeycomb panel, and it is possible to improve the strength, heat insulation, and sound insulation of the panel.

Further, by providing a plurality of air vent holes which are deviated from the axial direction of the cylindrical unit,
The air vent holes of the adjacent cylindrical bodies do not completely coincide with each other, so that it is possible to prevent the occurrence of clogging due to the brazing material at the time of brazing, and to allow the air in the cylindrical body to escape to the outside. Pressure adjustment can be performed within a time (claim 1). Also, by forming a concave groove on the side surface of the cylindrical single body and providing an air vent hole in the concave groove, the air vent holes of the adjacent cylindrical single bodies do not completely match, and the brazing material is used at the time of brazing. And the pressure can be adjusted within a short time (claim 2). Therefore,
Deformation of the surface plate due to expansion and contraction of air due to temperature change during molding can be prevented, and moldability can be improved.

In addition, the surface plate and the cylindrical body are formed of an aluminum alloy member, and at least the cylindrical body is formed of a clad material having a brazing material brazed on the surface thereof. a tubular alone in the heat treatment furnace can be integrally molded in close contact by brazing, it is possible to increase the strength of the honeycomb panel and dimensional accuracy (claims 1, 2).

And a core material 3 interposed in a space formed by the frame material 2.

The surface plate 1 is made of an aluminum alloy plate, and the frame 2 is made of an extruded aluminum alloy. The core material 3 is
Each of them is formed by a group of a large number of independent cylindrical single bodies 4 to form a hollow section partitioned into many. Therefore, a hollow part similar to the hollow part partitioned by the inner part can be formed also at the panel peripheral part.

In this case, at least the cylindrical element 4 of the surface plate 1, the frame member 2 and the cylindrical element 4 is an aluminum clad material using a brazing material (JIS A4045 or the like) on its outer surface. Is formed. Therefore, even when the cylindrical element 4 is formed by bending an aluminum alloy plate, the separated portions at both ends of the plate are joined by brazing after the honeycomb panel is formed,
The tubular unit 4 is completely tubular. In addition, it is also possible to form any of the surface plate 1, the frame material 2, and the cylindrical simple substance 4 with an aluminum clad material using a brazing material on the surface, or alternatively, the surface plate 1, the frame material 2, Instead of using an aluminum clad material for any of the cylindrical single bodies 4, a brazing material may be interposed between them, and the brazing material may be melted and brazed during heat treatment. In this case, a non-corrosive flux such as KF + AlF3 or KAl is used as the flux.
It is more preferable to join the surface plate 1, the frame member 2 and the cylindrical unit 4 using a flux such as F4 + K3AlF6 + K2AlF5.H2O.

The cylindrical unit 4 is formed by bending a plate member 4A made of, for example, an aluminum alloy (see FIG. 3 (b)).

The arrangement of the air vent holes 5 does not need to be a single row inclined with respect to the axis of the cylindrical unit 4 as shown in FIG. 3, for example, as shown in FIG. A plurality of air vent holes 5 may be provided in two rows that are inclined and intersect with each other at an appropriate interval. Further, as shown in FIG. The holes 5 may be provided or may be provided at random.

By providing the groove 6 on the side surface of the cylindrical unit 4 and providing the air vent hole 5 in the groove 6, the air vent holes 5 of the adjacent cylindrical units 4 do not completely coincide with each other. Although three air vent holes 5 are provided in FIG. 6, at least one air vent hole 5 may be provided.

In the above embodiment, the case where the cylindrical single body 4 is formed of a cylindrical cylindrical body has been described. However, the cylindrical single body 4 does not necessarily have to be cylindrical, and may be, for example, triangular.
It can be formed of a cylindrical body having an arbitrary shape such as a square or a hexagon. Further, the cylindrical single body 4 can be formed of a tapered cylindrical body 4a as shown in FIG. By forming the tubular single body 4 with the tapered tubular body 4a in this manner, when forming a honeycomb panel with a curved surface, it is possible to braze the tubular single body 4 in a more closely contacted state. In order to manufacture the tapered cylindrical body 4a, a notch 7 that forms a tapered portion in the height direction (axial direction) of the cylindrical unit 4 may be provided, for example, as shown in FIG. .

First, a frame member 2 is disposed around the peripheral surface of one of the surface plates 1, a plurality of cylindrical single bodies 4 are arranged on the upper surface of the surface plate in a state of being in contact with each other, and the other surface plate 1 is disposed on the upper surface. After covering, it is fixed with a mold (not shown). At this time, the air vent holes 5 of the adjacent cylindrical single bodies 4 do not completely coincide with each other, and are in a state where air can be vented. Then, the pair of fixed surface plates 1, the frame member 2 and the large number of cylindrical single bodies 4 are fixed to each other.
The core material 3 formed in contact with comprising a set group is inserted into the heat treatment furnace, appropriate temperatures (e.g., 640-650
° C) and integrally molded by brazing. At this time, since the inflated air in the cylindrical unit 4 escapes from the air vent hole 5, the pressure can be adjusted in a short time, and the deformation of the surface plate 1 can be prevented. Further, even when the air shrinks due to the temperature drop to the room temperature after the heat treatment, the pressure can be adjusted through the air vent hole 5, and the surface plate 1
Can be prevented from being deformed.

In the above embodiment, the case where the honeycomb panel is formed in a rectangular shape is described. However, the shape of the honeycomb panel may be an arbitrary shape other than the rectangular shape, such as a triangular shape or a trapezoidal shape. Further, in the above embodiment, the case where the cylindrical single body 4 is formed by bending an aluminum alloy plate material by bending is described. However, the cylindrical single body can be formed by an aluminum alloy extruded shape material. Further, in the above-described embodiment, the case of the honeycomb panel having the frame material 2 in the peripheral portion of the both face plates 1 has been described. However, the frame material 2 does not always need to be provided.
It is also possible to form a honeycomb panel with the surface plate 1 and the core material 3 by removing the mold after molding with a carbon mold or the like interposed therebetween.
