WIPO Patent Application WO/2022/261796
Kind Code:
A1
Abstract:
A dual-type manual coupling steel frame. A male joint (6) and a female joint (5) of a "three-piece sleeve coupler" are connected horizontally and vertically, and a diagonally-pulling contact point of a "single-hook coupler" is gathered together with said joints to form a round rod secured by a sleeve (19). The two coupling means are combined to complete a steel frame for construction of a stadium, an office building, or a home, as well as a steel frame for a tower crane, a gantry crane, a traveling crane, various types of bridge frame steel structural columns, a girder frame, etc. This saves construction time, material consumption, construction equipment and labor costs, and optimizes quality, accuracy, firmness, and service life.
