Detachable combined variable-cross section steel middle beam
The invention discloses a detachable combined variable-cross section steel middle beam. The detachable combined variable-cross section steel middle beam is composed of a uniform-cross section channel steel middle beam body, a variable-cross section steel middle beam body and a connecting device. The uniform-cross section channel steel middle beam body is composed of uniform-cross section channel steel, an anchor rod hole and bolt holes and located in a sheared area of a structure and mainly bears shearing force, and the anchor rod hole and the bolt holes are machined in the uniform-cross section channel steel. The connecting device is composed of a connecting plate and bolt holes machined in the connecting plate, and the connecting device is used for combining the uniform-cross section channel steel middle beam body and the variable-cross section steel middle beam body together. Variable-cross section treatment is conducted on the end of the variable-cross section steel middle beam body, and the cross section of the end of the variable-cross section steel middle beam body changes gradually so as to be the same as that of the uniform-cross section channel steel middle beam body. According to the detachable combined variable-cross section steel middle beam, profile steel with different sections is adopted for different stress areas, and thus the problem that the bearing capacity of an ordinary profile steel middle beam is insufficient or steel is wasted is effectively solved; the detachable combined variable-cross section steel middle beam has the advantages of being low in weight, convenient to disassemble and assemble, capable of being recycled and the like.
