Fusiform anchor head for large-diameter high-strength reinforcements of reinforced concrete beam-column joints and application of fusiform anchor head

Abstract

The invention belongs to the field of civil engineering, and particularly relates to a fusiform anchor head for large-diameter high-strength reinforcements of reinforced concrete beam-column joints and application thereof. The technical solution is as follows: the fusiform anchor head comprises an upper anchor head part, a middle anchor head part and a lower anchor head part, wherein the middle anchor head part is a hexagonal prism, the upper anchor head part and the lower anchor head part are hexagonal frustums, the center of the fusiform anchor head is a through hole and is provided with internal threads, the external surface of the fusiform anchor head is provided with annular grooves, an end of a beam reinforcement is provided with external threads, and the internal threads of the fusiform anchor head and the external threads of the end of the beam reinforcement are screwed together. The performance of the design of the fusiform anchor head is reasonable, construction is simple andhighly efficient, energy can be saved and consumption can be reduced in terms of economy, and the fusiform anchor head can help achieve a design concept and a construction method in which members areeasy to produce and convenient to mount and cost is appropriate.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a shuttle-shaped anchor head for large-diameter high-strength steel bars used in reinforced concrete beam-column joints and an application thereof. Background technique [0002] Prefabricated concrete technology is the key technology to change the way of traditional residential construction. Its structural force is clear, green and environmental protection, resource saving and other advantages are in line with the sustainable development strategy, reflecting the development direction of construction industrialization and housing industrialization. The inevitable result of economic progress is an important way to realize green building and green construction. [0003] In prefabricated concrete structural members, the use of large-diameter, large-spacing, high-strength steel reinforcement for beams and columns can effectively simplify the construction of joint nodes, im...
