Abstract

The invention belongs to the field of civil engineering, and specifically relates to a wedge-shaped clamping piece anchor head of a large-diameter high-strength steel bar for a reinforced concrete beam column joint and application. The wedge-shaped clamping piece anchor head of the large-diameter high-strength steel bar for the reinforced concrete beam column joint is characterized by comprising an anchor ring and three clamping pieces, wherein the anchor ring is in a cone frustum shape; a spiral anti-skid groove is formed in the outer part of the anchor ring; an inclined through hole is formed in the anchor ring; the three clamping pieces are in the same shape, and a wedge-shaped annular body is formed by the three clamping pieces; spiral grooves are formed in the clamping pieces; the three clamping pieces are wedged between the anchor ring and a beam steel bar of an assembly type concrete beam. According to the wedge-shaped clamping piece anchor head disclosed by the invention, the problems that the column section area in a multi-layer prefabricated concrete frame structure is small, the anchorage length of a steel bar cannot meet the requirements, the joint manufacturing cost ishigh, and the operation is complicated are solved.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a wedge-shaped clip anchor head used for a large-diameter high-strength steel bar at a reinforced concrete beam-column joint and its application. Background technique [0002] At this stage, prefabricated concrete structure buildings, as a green building with high efficiency, low energy consumption and easy modular production, have gradually become an indispensable part of the modern development of the construction industry. In order to adapt to the development of the economic level and the improvement of the technical level, and to promote the large-scale, stable and orderly development of prefabricated buildings, it is necessary to improve the production and construction quality of existing prefabricated buildings. The prefabricated concrete buildings with high-efficiency reinforcement have started due to their many advantages. Be the designer's choice. [0003] Th...
