Description of the Related Art The weight reduction of various equipment, especially the weight of transportation equipment, has been actively promoted because it enables reduction of fuel consumption and directly leads to environmental protection. The use of alloy materials is increasing.
Aluminum and its alloy materials are lightweight and have an optimum cross-sectional shape, for example, a panel structure that can increase rigidity and is excellent in smoothness, and is therefore suitable for transportation equipment such as vehicles and ships. Suitable as a member.

ニカムパネルの幅が限定される。Panel structures include hollow profiles and honeycomb panels. The hollow shape member is formed by extruding an aluminum alloy because a plurality of pillar plates are installed between two face plates that are parallel to each other with a certain distance.
The width of the hollow profile that can be formed is limited. On the other hand, in a honeycomb panel, a frame material is arranged around the periphery of a honeycomb core of a core material, face plates are arranged on the upper and lower surfaces of the honeycomb core, and in this state, they are placed in a brazing furnace and brazed together to form an integral body. As it is manufactured, the size of the brazing furnace limits the width of the honeycomb panel that can be manufactured.

る。Therefore, it is essential to join the hollow shape members and the honeycomb panels together, and arc welding (TIG, MIG) is applied to the joining from the viewpoint of strength. However, in arc welding, due to thermal strain during welding, There is a problem that the aluminum alloy material is deformed. For parts where the appearance is important, it is necessary to remove the surplus that is formed during arc welding, and further, the strength decreases due to the heat effect around the weld due to the large heat input during welding, and the panel structure is thickened accordingly. It must be designed to be meat, which reduces the light weight effect of the corner.

る。The vehicle structure includes a 6000 series (Al-M
The extruded profile of (g-Si-based) aluminum alloy is most often used. However, in the case of a normal 6000-based aluminum alloy, the heat input during arc welding causes the welding heat-affected zone (HA).
Z) is softened, and the original strength of the extruded aluminum alloy profile is greatly impaired. In addition, there are cases where defects such as blowholes and solidification cracking, which are peculiar to arc welding, may occur, and because the welded part is repaired and re-welded, a lot of man-hours are required and the appearance of the welded part deteriorates. There are difficulties.

で得ることが可能となる。As a joining method with less heat input and less degree of softening and distortion, there is a butt friction joining method of aluminum and its alloy shape members (Japanese Patent Laid-Open No. 9-309164, etc.). According to this method, the hollow joints and the honeycomb panels are friction-joined to each other, whereby deformation of the joints and the periphery thereof is suppressed, and good joining can be obtained in a short time.

るため、次のような問題点が生じる。When the friction welding is applied to join the panel structures made of aluminum and its alloy to each other, various disadvantages caused by the conventional arc welding can be eliminated. However, the panel structure made of aluminum and its alloy, that is, the hollow shape and the honeycomb panel, are made as thin as possible of the face plate, the pillar plate or the frame material in order to reduce the weight. Problems arise.

る。That is, when the hollow shape members a are friction-welded to each other, as shown in FIG. 11, the pillar plates b are abutted with each other without any gap, and the friction welding tool d is attached along the welding line c. Although it is moved, during friction welding, a downward force acts on the joint f due to the reaction that the metal of the hollow shape member a immediately below the pin e of the friction welding tool d is discharged to the surface, and therefore the first portion acts. Next, the pillar plate b is deformed or buckled due to insufficient strength, and as shown in FIG.
Defects in the plastic flow region, such as tunnel-shaped holes h and cracks, are likely to occur due to the bulge g of the metal and the lack of metal in the joint.

FIG. 1 is a cross-sectional view of a joining panel structure showing an embodiment of the present invention. In FIG. 1, a joining panel structure 1 is a hollow shape member, and a plurality of pillar plates 3 are installed between two face plates 2 and 2 which are parallel to each other with a constant interval, and a panel structure 4 is formed. And a thick wall portion 6 is formed at a corner portion 5 between both ends of the pillar plate 3 located at the end portion of the panel structure 4 and the two face plates 2.

はコスト面から不利となる。When the joining panel structure 1 is made of aluminum (including aluminum alloy, the same applies hereinafter), it is integrally formed by extrusion molding. Therefore, although the bonding panel structure 1 can be manufactured with theoretically any length in the extrusion direction, the widthwise dimension is regulated by the extruder, and the width is too wide. Manufacturing is disadvantageous in terms of cost.

る。Therefore, a large-sized panel is manufactured by butt-joining the above-mentioned joining panel structure 1 with the face plates 2 and 2 and the column plate 3 located at the ends thereof. Conventionally, arc welding has been performed from the viewpoint of strength, but it is preferable to employ friction welding because of the harmful effects of a large amount of heat input during welding.
On the other hand, in the joining panel structure 1, the face plates 2 and 2 and the pillar plate 3 have the necessary minimum thickness in order to maximize the weight reduction.

In order to frictionally bond the members to each other, the bonding surfaces 10 are butted against each other and pressed and restrained by a jig (not shown). The hard pin 12 of the friction welding tool 11 is rotated at a high speed along the joining line to pierce one end of the joining surface 10 and moved to the other end along the joining line to perform friction joining. Then, the joining panel structure 1 is turned upside down and frictionally joined in the same manner.
The joining panel structures 1 can be frictionally joined to each other by 3, and a large panel can be obtained.

的を達成することが難しくなる。As shown in FIG. 2, the width of the thick portion 6 (β + β = 2β) is at least the width of the region in which plastic flow is caused by friction welding, that is, the width of the joining portion 13 (α + α = 2α). 2 times or more (2 × 2α ≦ 2β− → 2α
≤ β). The double or more thick portion 6 does not cause cavities due to swelling or lack of metal during friction bonding, so that the face plates 2 and 2 and the column plate 3 can be made to have a necessary minimum thickness. . However, if this magnification is too high, the thick portion 6 is provided more than necessary, which is disadvantageous in terms of weight reduction. If the amount is less than twice, bulging may occur during friction welding or voids may be formed due to lack of metal, making it difficult to achieve the object of the present invention.

手くいかない結果になる。The joint portion 13 is related to the thickness of the face plate 2. That is, as shown in FIG. 3, it is preferable that the region (α ₁ ) in which plastic flow is caused by friction welding is in the range of 1 to 3 times the thickness (t) of the face plate 2 (t ≦ α ₁ ≦ 3t). When (α ₁ ) is in this range, the joint strength of the joint portion 13 becomes sufficient, and friction joining becomes easy. If it is less than this range, the joint length will be insufficient and the joint strength will be insufficient,
Exceeding this range causes heat input and deformation, resulting in poor friction welding.

す。The thickness of the column plate 3 is related to the workability of friction welding. That is, as shown in FIG. 4, the thickness (γ) of the pillar plate 3
Is preferably in the range of 0.5 to 3 times the thickness (t) of the face plate 2 (0.5t ≦ γ ≦ 3t). When the thickness (γ) of the column plate 3 is within this range, buckling does not occur during friction welding and the weight does not increase so much. Below this range, there is a risk of buckling due to the downward force on the column plate 3 that occurs during friction welding, and above this range, the weight is unnecessarily increased, and the result of weight reduction cannot be achieved. FIG. 13 shows the relationship between the thickness (t) of the face plate 2 and the thickness (γ) of the column plate 3.

However, it cannot be implemented without the thick portion 6. The thickness of the face plate 2 of the present invention is 3 mm.
In this case, the friction welding can be performed even if the thickness of the pillar plate 3 is 3/2 = 1.5 mm. However, if the thickness of the face plate 2 is 3 mm without the thick portion 6, the thickness of the pillar plate 3 is 6/2 = 3 m.
It cannot be implemented unless m.
