Major diameter steel bar integral vertical hoisting apparatus in high pier construction

Abstract

A major diameter steel bar integral vertical hoisting apparatus in high pier construction is characterized in that the contact flange of two section steel clamps arranged in parallel is provided with a plurality of jaw grooves forming interference fit together with steel bars, two ends of the two section steel clamps are respectively provided with a left pin hole plate and a right pin hole plate, a latch bolt traverses through the left pin hole plate and the right pin hole plate to connect the two section steel clamps, and two ends of each of the section steel clamps are respectively provided with a hanger. The section steel clamps with the jaw grooves are arranged, so the major diameter steel bar integral vertical hoisting apparatus in high pier construction can realize one-shot vertical hoisting of a plurality of steel bars, ensures the quality of reinforced bars, and reduces the risk and cost of construction. The apparatus can guarantee the fastness and the safety of hoisting of major diameter steel bars, and greatly improves the installation efficiency of high pier construction steel bars.

Description

technical field [0001] The invention relates to the field of vertical hoisting of large-diameter steel bars, in particular to an overall vertical hoisting device for large-diameter steel bars in high pier construction. Background technique [0002] In the construction of high piers, steel bars with a diameter of more than 20mm and a length of more than 2.5m are often used. Due to the large weight of such steel bars and the small working surface of high piers, mechanical equipment must be used for winding during construction. The installation is then completed by hoisting a single piece. This hoisting method is not only inconvenient to operate, but the installation of butt joints of steel bars often tends to be tilted. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an overall vertical hoisting device for large-diameter steel bars in the construction of high piers, which can ensure the quality of butt joints of st...
