Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining panel formed by butt-welding a plurality of panels formed by brazing.

[0002]

2. Description of the Related Art Conventionally, in order to form a panel, a pair of face plates are arranged to face each other, an edge member is interposed between edges of the face plates, and each of the face plates is brazed to the edge member. Generally, it is formed. In this case, in order to form a larger panel, the brazing panels formed as described above are butted together, and the butted edge members are welded to each other to obtain a panel of a required size (hereinafter referred to as a “joining panel”). "). In some cases, the brazing panel is brazed with a core material, for example, a honeycomb material interposed between a pair of face plates.

[0003]

However, according to the prior art, the panel is distorted by the high temperature during brazing. This distortion is caused by waving and bowing of the panel surface,
Alternatively, it appears as bowing of the joint surface joining the panels. When these strains are present, the butted surfaces of the panels do not coincide with each other, so that it is difficult to perform welding, and the welded joint surfaces are also irregular, resulting in poor appearance.

Further, if the panels are warped, a gap is formed between the panels butted for welding, and the arc at the time of welding penetrates, making welding impossible.

[0005] It is an object of the present invention to improve the flatness or curvature of a bonded panel.

[0006]

In order to solve the above-mentioned problems, in the joint panel according to the present invention, grooves extending along the longitudinal direction of the edge members are formed on the abutting surfaces of the edge members of the plurality of panels. A rigid member (hereinafter, also referred to as a “rigid member”) is fitted in the groove. According to the joint panel having such a configuration, the rigid member is fitted into the groove of the edge member of the panel at the time of joining. As a result, the butted edge members are restrained in the in-plane direction, and the butted edge members can be aligned and surface-matched, and butt welding can be performed. Further, the strain generated during welding can be reduced due to the presence of the rigid member. As a result, it is possible to reduce the irregularity of the joint portion surface of the joint panel, and to improve the flatness or the curvature of the joint panel.

The rigid member preferably has a function as a backing material when the edge members of the plurality of panels are butt-welded. In other words, if there is a bow in the joint surface of the edge member of the brazed panel, a gap will be formed between the joint surfaces, but the gap between the joint surfaces will be closed by the function of the backing material, preventing arc loss during welding and preventing welding. enable.

The cross-sectional shape of the groove of the edge member can be, for example, rectangular. The shape of the rigid member may be any shape such as a rod shape or a flat bar shape that matches the cross-sectional shape of the groove of the edge member. Then, the rigid member is fitted by being inserted along a through hole formed with the grooves of the panel joining surface facing each other. The rigid member may be solid or hollow, and an appropriate member is used according to the type, application, size, and the like of the panel to be joined. The material is preferably a metal, but is not limited thereto. Any material having rigidity may be used, and it is more preferable that the material has a function as a backing material for welding.

Further, the grooves of the edge member may be provided in two or more rows along the longitudinal direction, and a rigid member may be fitted in each groove. Thereby, for example, the curved panels can be joined together to form a curved joined panel, and the degree of freedom in joining the panels increases.

The abutting surface of the edge member of the panel may protrude from the end surface of the surface plate of the panel, or the abutting surface of the edge member and the end surface of the surface plate may be flush.
A groove can be formed in the edge member by making the butting surface of the edge member protrude from the end surface of the surface plate of the panel.

The panel formed by brazing may be one integrally brazed with a core material, for example, a metal honeycomb material interposed between a pair of face plates. The edge member of the panel is appropriately provided at the edge of the panel depending on the purpose of use of the joined panel. For example, the panel may be rectangular and provided on one or two opposite sides of the panel, or provided on the entire periphery. The panel in which the edge member is provided on one side or two opposite sides can be a joint panel extending in one direction. The panel in which the edge member is provided on the entire circumference may be a joining panel extending in all directions.

When the material of the panel is aluminum or an aluminum alloy (hereinafter referred to as "aluminum"), the aluminum is brazed at a temperature of about 600.degree. When the material is aluminum, the edge member and the member having rigidity are preferably made of extruded aluminum. Extruded aluminum material has good moldability by extrusion processing,
A solid material or a hollow material can be easily obtained, and the weight can be reduced. TIG welding or MIG welding is used for welding the aluminum edge members.

The joining panel can have an appropriate shape depending on the shape of the brazing panel and the shape of its edge members. When the brazed panel is a flat panel, the joining panel may be a flat planar panel or a polygonal polygonal panel. When the brazed panel is a curved panel, the entire joining panel can be a curved panel.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a bonded panel according to the present invention.

FIG. 2 is a perspective view showing a first embodiment of the bonded panel according to the present invention. In the joint panel of the first embodiment, the panel 2 and the panel 3 are welded by abutting the edge members 13 and 14 in a direction 16 parallel to the surface of the panels and orthogonal to the longitudinal direction 19. The panels 2 and 3 are arranged in parallel at a predetermined interval, and the edge members 13 and 14 are interposed between the edge portions 6 of the pair of facing surface plates 4a and 4b, and the surface plates 4a and 4b are attached to the edge members 13 and 14. Each is formed by brazing.

The above-mentioned predetermined interval is determined according to the thickness T of the panel 2. For example, in the case of FIG. 2, it is a dimension obtained by subtracting 2t which is twice the thickness of the surface plates on both sides from the thickness T of the panel. In the present embodiment, a pair of surface plates 4a,
It is brazed with a honeycomb material (core material) 10 interposed between 4b. In addition, the edge members 13 and 14 in the panels 2 and 3 of the first embodiment are the same as those generally referred to as frame members provided on the panels, and are provided on two sides in the longitudinal direction 19 of the edges of the panels 2 and 3. And two sides in the longitudinal direction 19 and two sides in the direction 16 perpendicular to the longitudinal direction, that is, a total of four sides.

The material of the panels 2 and 3 is an aluminum material and is brazed at a temperature of about 600 ° C. Surface plate 4
For a and 4b, a rolled aluminum plate can be suitably used.
As the honeycomb material 10, for example, a processed aluminum plate or aluminum foil is used. Edge member 13,
For 14, for example, an extruded aluminum material can be suitably used. Similarly, as the backing material 20 described later, an aluminum plate or an extruded aluminum material can be suitably used. Well-known TIG welding or MIG welding is used for welding between aluminum edge members. The thickness of the surface plate 4a and the thickness of the surface plate 4b do not necessarily have to match.

FIG. 1 is a sectional view taken along line II of FIG. In the joint panel of the first embodiment, the edge members 13 and 14
The groove 17 is formed on the abutting surface 15 along the longitudinal direction 19 of the edge members 13 and 14 (the direction perpendicular to the plane of FIG. 1 and shown in FIG. 2). Groove 17 of edge member 13
A welding backing material 20 is fitted as a rigid member in a space having a rectangular cross section where the groove 17 of the edge member 14 and the groove 17 abut against each other.

The edge members 13 and 14 are made of a hollow material and are provided at both ends (upper side and lower side in FIG. 1) of a butt surface 15 of the edge members.
8 are formed. In this case, the groove 17 of the edge member is formed between the groove portions 18.

The backing member 20 is formed in a solid shape with a shape conforming to the cross-sectional shape of the groove 17 of the edge member, in this case, a rectangular cross section (rectangle), and is provided along the groove 17 as a threading member. After fitting the backing material 20 between the grooves 17, the outer V-shaped groove formed by the two grooved portions 18 butted together is welded. In this case, the butted surface side of the edge member protrudes outside the edge 6 of the face plate.

The joint panel of the first embodiment having the above structure operates as follows. That is, the edge member 13,
A groove 17 extending along the longitudinal direction of the edge member is formed on the butting surface 15 of the edge member 14, and a backing material 20 for welding is fitted into the groove 17, so that the edge members 13, 14 are joined to each other. Edge member 1 constrained and abutted inward
Positioning and surface matching of 3, 14 can be performed. By welding the two groove portions 18 in this state, the strain generated by welding can be reduced. As a result, the degree of flatness or the degree of curvature of the joined panel can be improved. In addition, the irregularity of the joint surface of the joint panel can be reduced.

When the brazed panels 2 and 3 are bowed at the abutting surfaces, a gap is formed between the abutting surfaces of the panels. By backing this gap with the backing material 20, arc omission at the time of welding is prevented and welding is enabled.

In addition, when the panels are butt-welded, distortion due to welding occurs. At this time, since the panel is welded in a state where the position and the surface have been aligned,
The joint panel is substantially symmetrically distorted around the welded portion in the same tendency, has a small degree of distortion, and can easily correct this distortion.

Next, advantages of the joined panel of the first embodiment are as follows. Even if the panels 2 and 3 are slightly distorted by brazing, the backing plate 20 is fitted in the grooves of the edge members 13 and 14, so that the alignment and the surface alignment between the panels 2 and 3 can be easily performed. The arc does not occur during welding of the panel edge members 13 and 14, and the welding is easily and beautifully finished. Since the distortion of the joint panel after welding is distorted to the same tendency on the left and right, labor for removing the strain is reduced and labor is saved. The present invention is also applicable to joining panels 2 and 3 having curved surfaces.

In the joint panel of the third embodiment, the groove 17 of the edge member is divided into two in the direction perpendicular to the surfaces of the panels 2 and 3, that is, the surface plate 4a or the surface plate 4b. A backing material 20 is fitted between each of the divided grooves 17. By providing two divided grooves 17 in the direction perpendicular to the panel surface, the degree of freedom of joining between the panels 2 and 3 is increased. For example, flat panels are made into multiple faces or curved panels are made into curved faces. It can be joined and can be used as a multi-layered or curved roofing material for buildings. The structure and operation of the other parts in FIG. 4 are the same as those of the first embodiment shown in FIGS.
