造コストが高くつくという欠点がある。(Prior Art) Conventionally, a sanderch plate made of a porous metal body with a honeycomb structure and a metal plate is known as a lightweight material. This material is made by bonding a porous metal body and a metal plate with a sheet, powder, or liquid organic adhesive.In this structure, the heat resistance of the joint is limited because the heat resistance of the adhesive itself is low. It has the drawbacks of low adhesive properties and high manufacturing costs due to the time-consuming process of applying the adhesive.

が望まれている。 Also, a method of soldering may be considered instead of the above adhesive, but in this case, the flux used as pre-treatment will penetrate into the porous metal, making it difficult to remove by cleaning, and furthermore, the manufacturing cost will be high. There is a drawback. As architectural or structural members, there is a desire to develop members that are lightweight, have excellent flame retardancy, and can be manufactured at low cost.

The second aspect of the present invention is to form minute irregularities on the surface of a metal reinforcing member, and apply electricity to the end face of the foamed metal with the end face crimped against the irregular surface, thereby heating and melting and joining. It was designed so that

Their joint surfaces are welded together. That is, metal plates 3 serving as reinforcing materials are placed on both sides of the foam metal plate 2.
are combined to form a composite material (foamed metal material with reinforcing material) 1 having a sanderch structure.

る芯材を形成させる。 Next, a method for manufacturing the composite material 4 shown in FIG. 2 will be explained. First, a foamed metal is manufactured by a known method, and the foamed metal plate 2 is manufactured by cutting it into plate shapes. As shown in FIG. 3, one side of the metal profile 5 is placed opposite to the end surface 7 of the foamed metal plate 2, each is sandwiched between electrodes 8, and the opposing surfaces are pressed together, and a current is applied from a power source 9. The crimped parts are heated, melted, and bonded to form a core material in which the metal mold material 5 and the foamed metal plate 2 are bonded together at the joint part 10, as shown in FIG.

が共に溶融して強固に結合することになる。 Note that the joining end surface of the metal profile 5 is made into an uneven surface 6 in which minute unevenness is formed in advance by means such as grinding. The reason why this uneven surface 6 is formed is as follows. In other words, when the foam metal and the smooth surface of the mold material 5 are crimped and energized, only the foam metal melts because the surface of the mold material 5 has a much larger heat capacity than the diaphragm that makes up the cells of the foam metal. Since the mold material 5 does not melt, it is not possible to make a strong bond. However, when minute irregularities are formed on the bonding surface of the mold material 5, the convex portions have a small heat capacity and melt, and this portion and the foamed metal are melted together and firmly bonded.

うな複合板とする。 Next, as shown in FIG. 5, metal plates 3 are bonded to both the front and back surfaces of the core material, but at this time, the bonding surface of the metal plates 3 is made to have an uneven surface 6 for the same reason as above. Then, electricity is applied while the metal plate 3 is crimped to the core material to heat and melt the joint, forming a composite plate as shown in FIG. 6.

It is sandwiched from above and below by shaped metal members 11 and energized.
The joint surfaces are melted to form a prismatic composite material 12 as shown in FIG. In this case as well, the uneven surface 6 is formed on the joint surface of the metal profile 11.
