Description

The present invention relates to an uneven surface member having an uneven surface and a composite material constructed by using the uneven surface member.

A tree provided with a steel member (concave and convex surface member) having a roughened portion bitten by a wooden member (wooden member) on the surface and a wooden member (wooden member) crimped to the surface of the steel member. -A steel hybrid structural material (composite material) is known (see Patent Document 1).

Japanese Unexamined Patent Publication No. 2018-20347

However, the roughened portion formed on the surface of the steel member as the uneven surface member disclosed in Patent Document 1 is a weight-shaped or tetrapod-shaped needle-shaped protrusion or a burr-shaped needle-shaped protrusion, and the needle is the needle. Since the protrusion is formed of a small piece of steel with a sharp tip, it is easily deformed.
That is, the wood-steel hybrid structural material as a composite material disclosed in Patent Document 1 has a structure in which a needle-like protrusion instead of a nail is used at the joint for the purpose of preventing brittle fracture of the wood member. If a force is applied to the needle-shaped protrusion, the needle-shaped protrusion is deformed and a large force cannot be transmitted. Therefore, the force transmitted to the steel member is effectively transmitted to the wood member via the needle-shaped protrusion. However, the force transmitted to the steel member (concave and convex surface member) cannot be effectively borne by the wooden member (wooden member (joined member)).
Further, according to the wood-steel hybrid structural material as a composite material disclosed in Patent Document 1, needle-like protrusions bite into the inside of the wood member, and stress is applied to the surface of the wood member that comes into contact with the needle-like protrusions. Is repeatedly transmitted, so that local sinking by the needle-shaped protrusions easily progresses inside the wood member, so that the force transmitted to the steel member is effectively transmitted to the wood member via the needle-shaped protrusions. However, the force transmitted to the steel member (concave and convex surface member) cannot be effectively applied to the wood member (joined member).
As described above, in the composite material disclosed in Patent Document 1, the steel member and the wood member are formed via needle-like protrusions made of small pieces of steel having a sharp tip formed on the surface (plate surface) of the steel member. Since the structure is joined, when a force is applied to the steel member, the needle-shaped protrusions are easily deformed and the needle-shaped protrusions apply local repetitive stress to the inside of the wood member.
That is, the steel member (plate) with needle-like protrusions used for joining the composite material disclosed in Patent Document 1 is originally a member for preventing the wood member from splitting when the drift pin is driven into the wood member. Yes, it is thin and has many openings, so it is not suitable for transmitting a larger force.
That is, the steel member with needle-shaped protrusions disclosed in Patent Document 1 has a structure in which a large number of needle-shaped protrusions are cut up from a large number of parts of the thin plate and a large number of needle-shaped protrusions are provided on the surface of the thin plate, so that the steel member has many openings. Also, the needle-like protrusion is composed of small pieces of steel with a sharp tip. For this reason, when a force is applied to the steel member, the entire plate or the needle-shaped protrusions are deformed, and the needle-shaped protrusions tend to locally sink into the wood member, so that the wood member becomes It is easily damaged and the force applied to the steel member is not effectively transmitted to the wood member through the needle-like protrusions.
As described above, in the joint structure between the steel member and the wood member such as the composite material disclosed in Patent Document 1, the force transmitted to the steel member as the uneven surface member is used as the wood member to be joined. There was a problem that it could not be effectively burdened.
The present invention is configured by using a concave-convex surface member capable of effectively bearing a force transmitted to the concave-convex surface member to a member to be joined to the concave-convex surface of the concave-convex surface member, and the concave-convex surface member.
