Dry-type beam column connection structure for prefabricated reinforced concrete buildings

Abstract

The invention discloses a dry-type beam column connection structure for prefabricated reinforced concrete buildings. The dry-type beam column connection structure is characterized by comprising a hexagonal connection framework and an embedded framework, and one end of the embedded framework is embedded to one or two ends of a prefabricated reinforced concrete beam or vertical column. The connection framework is positioned on the top surface of a vertical column or between upper and lower vertical columns and fixedly connected with the embedded framework on the end face of the vertical column through bolts, and beams are arranged on the lateral sides of the connection framework and fixedly connected with the connection framework through the embedded framework by the aid of bolts. The dry-type beam column connection structure has advantages of high connection strength, short construction period, high construction precision, high structural integrity, convenience in mounting and surface attractiveness.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a prefabricated assembled reinforced concrete building, which is a dry beam-column connection structure for the prefabricated assembled reinforced concrete building. Background technique [0002] With the rapid development of my country's economy, China's construction industry has entered a healthy and rapid development track, with a steady increase in annual output value and a huge construction industry. Prefabricated reinforced concrete buildings are beneficial to save resources and energy, reduce construction pollution, improve labor production efficiency and quality and safety levels, promote the deep integration of the construction industry and information industrialization, cultivate new industries and new kinetic energy, and promote the resolution of excess capacity. It has become the development trend of new building structures in my country. It is of great sign...

Problems solved by technology

[0003] Judging from the research and development results of the beam-column connection structure of prefabricated reinforced concrete buildings at home and abroad, there are mainly four problems: First, the beam-column connection structure of the existing technology is mostly "wet" connection, resulting in subsequent construction due to Waiting for the concrete to set and harden can not continue construction and prolong the construction period; second, the beam-column connection structure of the prior art is weak in rigidity and strength, and cannot meet the design principle of "strong joints, weak members"; third, the beam-column connection of the prior art The operation of the connection structure is complicated and the construction is inconvenient; the fourth is that the beams of the existing beam-column connection structure are hoisted after the columns are installed and in place, which makes it very difficult to hoist the beams in place, and because the beam can be smoothly positioned between the columns, the beam and the columns There must be gaps between beams and columns that are not "tight" connected
