Description

Safe and stable steel construction cat ladder Technical Field The invention relates to a ladder stand for construction, in particular to a safe and stable steel structure construction ladder stand. Background When carrying out the construction of high-rise building, mostly need with the help of instrument such as cat ladder about, because cat ladder needs to bear constructor, its stability and security performance requirement are higher. But traditional cat ladder most simple structure comprises simple steelframe and cat ladder, need hang the cat ladder when using on the steel climbs the frame after reuse iron wire and carries out the ligature fixedly. The cat ladder and the column body are bound and fixed by the iron wires, the cat ladder which is simply hung on the steel climbing frame can be fixed, and the cat ladder is prevented from shaking when stressed unevenly due to manual climbing. And when carrying out iron wire ligature to the cat ladder that hangs in the high altitude, a relatively loaded down with trivial details and time-consuming process, very big consumption human cost and time cost, and easily produce more unsafe factors. Disclosure of Invention In order to overcome the defects of the prior art, the invention provides the steel structure installation cat ladder which is provided with the connecting piece with the limiting structure and the hanging structure capable of locking to ensure the hanging stability. The technical scheme includes that the safe and stable steel structure construction ladder comprises a column body, a ladder stand and a connecting piece, wherein the connecting piece is fixed on the column body, a hanging structure is arranged at the end of the ladder stand, the ladder stand is hung on the connecting piece through the hanging structure, a locking structure is arranged on the hanging structure, a limiting structure is further arranged on the connecting piece, and the locking structure and the limiting structure are respectively used for limiting and locking the ladder stand on the connecting piece. As the improvement of above-mentioned technical scheme, the connecting piece includes fixed block, connecting block and stores pylon, the fixed block is fixed to be set up on the cylinder, the connecting block is used for being connected with the fixed block, the stores pylon is used for hanging cat ladder, limit structure sets up on the stores pylon.
