Connecting structure and method for prefabricated columns and prefabricated beams of fabricated building frame structure

Abstract

The invention discloses a connecting structure and method for prefabricated columns and prefabricated beams of a fabricated building frame structure. The connecting structure comprises the prefabricated columns and the prefabricated beams. At least one hidden bracket section is arranged on each prefabricated column in an embracing mode, and each hidden bracket section is internally provided with abracket longitudinal reinforcing rib. A prefabricated beam lap joint is arranged at the outer end of each hidden bracket section, and prefabricated beam connecting steel plates are pre-buried in theupper end faces and the lower end faces of the prefabricated beam lap joints correspondingly. The prefabricated beam connecting steel plates and the bracket longitudinal reinforcing ribs are connected. Prefabricated beam longitudinal reinforcing ribs are arranged in the prefabricated beams, and the two ends of the prefabricated beams are provided with bracket section lap joints matched with the prefabricated beam lap joints correspondingly. Bracket connecting steel plates are pre-buried in the upper end faces and the lower end faces of the bracket section lap joints correspondingly. The bracket connecting steel plates are connected with the prefabricated beam longitudinal reinforcing ribs. Each prefabricated beam is connected to the prefabricated beam lap joints of the hidden bracket sections on the two corresponding prefabricated columns in a lap-joint mode correspondingly, and the bracket connecting steel plates on the bracket section lap joints and the prefabricated beam connectingsteel plates on the prefabricated beam lap joints are connected.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a connection structure and method for prefabricated columns and prefabricated beams of prefabricated building frame structures. Background technique [0002] The construction industry is a pillar industry that drives my country's economic development. According to the statistics of the Ministry of Housing and Urban-Rural Development: Since 2009, the proportion of the added value of the construction industry to the GDP has always remained above 6.5%. In recent years, the state has strategically determined to promote the development of construction industrialization, and has issued a series of policy documents. [0003] At present, the level of construction industrialization in developed countries in the world is relatively high. For example, the construction industrialization of European and American countries reaches 75%, Sweden is as high as 80%, and Japan can r...
