Steel-concrete structure connecting component

The utility model relates to the technical field of guardrails, and discloses a steel-concrete structure connecting part which comprises a concrete block and two sets of embedded parts, the embedded parts are embedded in the concrete block, and the guardrails are placed at the tops of the embedded parts. Limiting grooves are formed in the two sides of the lower surface of the guardrail, clamping grooves are formed in the two sides, close to the limiting grooves, of the guardrail, and the clamping grooves communicate with the limiting grooves. By arranging the clamping blocks, the screw rods and the sliding rails, in the using process of the steel-concrete structure connecting part, the screw rods can be rotated anticlockwise to drive the clamping blocks b to move along the sliding rails until the clamping blocks a and the clamping blocks b are completely separated from the clamping grooves of the guardrail, then the guardrail is lifted upwards, and the guardrail is disassembled and replaced; by means of the d
