Lifting frame adopting independent framework foundation and operating method

Abstract

The invention discloses a lifting frame adopting an independent framework foundation and an operating method. The lifting frame comprises a steel frame, bottom square steel and two pieces of channel steel; a rectangular frame formed by welding four pieces of square steel is arranged at the top end of the steel frame, the four vertexes of the rectangular frame are perpendicular to four pieces of vertically-downward square steel welded to the plane of the rectangular frame respectively, and two pieces of parallel square steel are arranged at the bottom end of the steel frame and each welded between the ends of one pair of square steel perpendicular to the plane of the rectangular frame; a plurality of bolt holes are formed in the two pieces of square steel arranged at the bottom end of the steel frame at equal intervals; the bottom square steel is perpendicularly fixed between the two pieces of square steel arranged at the bottom end of the steel frame through bolts; the two pieces of channel steel are installed on the lower end faces of the bottom square steel located on the two sides of the bottom end of the steel frame through bolts respectively in the modes that channel openings face upwards. According to the lifting frame, the structure that the steel frame formed by welding the square steel is detachably connected with the bottom square steel and the channel steel is adopted, the lifting frame is provided with lifting points itself to achieve lifting, the number of the bottom square steel can be freely regulated according to a model structure, the lifting process is stable, and the safety performance is high; in addition, operation is convenient, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of model structure hoisting, in particular to a hanger and an operation method for a frame independent foundation. Background technique [0002] The general structural model needs to be hoisted to the target position after the completion of fabrication. Since the structure of each model is different from the test, the hoisting device used will also affect the success of the hoisting and the test, so it is very important to adopt a hoisting method suitable for the structural model and test. The general structural model adopts a rigid base, and a lifting point is set on the rigid base for direct lifting. If the model structure uses an independent foundation, the lower part of the model cannot be equipped with a rigid base, so the method of using a rigid base for hoisting is no longer used. In addition, due to the structural scale reduction, the bearing capacity of the structural components is limited, and it...
