Reinforcement cage lifting part

Abstract

The invention relates to the technical field of buildings, in particular to a reinforcement cage lifting part used for lifting a reinforcement cage in building. The reinforcement cage lifting part comprises a lifting rod and a connection lifting rod which are matched with each other in an inserting mode, the lifting rod and the connection lifting rod are half-cylinder rods, the wall of the lifting rod and the wall of the connection lifting rod comprise arc-shaped surfaces and planes, inclined catching grooves are formed in the center of the plane of the lifting rod, and inclined inserting lugs are arranged at the center of the plane of the connection lifting rod. A hook comprises a direct connection section, a bearing section and a specially-shaped free section, a lock catch hook is hinged to the direct connection section, the upper portion of the specially-shaped free section is provided with a pin hole in the direction perpendicular to the plane where the hook is located, the free end of the lock catch hook is provided with a pin hole corresponding to the pin hole in the hook, the specially-shaped free section is fixedly connected with the free end of the lock catch hook through a plug pin inserted into the pin holes, and the lifting rod is provided with a hoop piece which is used for clasping the lifting rod and the connection lifting rod. The reinforcement cage lifting part is simple in structure, low in cost, convenient to disassemble and assemble, capable of being recycled and long in service life. When the reinforcement cage lifting part is used, the reinforcement cage is little in shake, stable in lifting and safe to operate.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a tendon cage hanger for lifting a tendon cage in construction. Background technique [0002] The general construction process of pile foundation reinforcement cage installation is as follows: the reinforcement cage is transported to the site, the crane is hoisted into the hole, the appropriate length of the lifting ring is processed according to the positional relationship between the reinforcement cage and the hole, the lifting ring is welded to the reinforcement cage, the position of the reinforcement cage is adjusted, and the The steel cage is fixed. The existing technology has the following disadvantages. Due to the unevenness of the ground at the orifice, the lifting ring needs to be processed separately according to the site conditions every time, which is time-consuming and labor-intensive. After one use, it needs to be cut off from the steel cage by gas welding,...

Problems solved by technology

The existing technology has the following disadvantages. Due to the unevenness of the ground at the orifice, the lifting ring needs to be processed separately according to the site conditions every time, which is time-consuming and labor-intensive. After one use, it needs to be cut off from the steel cage by gas welding, which is basically scrapped. Welding, welding quality cannot be guaranteed

For example, Chinese Patent No. 201220372273.5 discloses a pile foundation reinforcement cage ring, which is inserted into the lower tube through the upper tube and adjusted up and down through the vertically arranged pin holes on the upper tube and the lower tube. There are pin holes, the lower tube is a hollow tube, its strength is not high, and its tensile and load-bearing capacity is not high in some steel cages, and cracks are prone to appear at the overhead holes, which will affect the hoisting safety of the steel cage; at the same time, it adopts The anti-floating clip is not completely fixed on the steel cage, and it is easy to slide out
