Abstract

The invention relates to a fabricated concrete prefabricated column dry-type connecting node and a construction method, the fabricated concrete prefabricated column dry-type connecting node comprises an upper concrete prefabricated column and a lower concrete prefabricated column, a first connecting device is pre-buried in the upper concrete prefabricated column, and the first connecting device comprises a plurality of anchor bars and an upper connecting plate anchored by longitudinal bars; a second connecting device is pre-buried in the lower concrete prefabricated column, and the second connecting device comprises a plurality of anchor bars and a lower connecting plate anchored by longitudinal bars; a sigma-shaped upper gusset plate is fixedly welded at the lower end of the upper connecting plate, and a sigma-shaped lower gusset plate is fixedly welded at the upper end of the lower connecting plate; the upper gusset plate and the lower gusset plate are correspondingly provided with penetrating holes, the upper gusset plate and the lower gusset plate are connected through bolts at the penetrating holes, and the gusset plates and the connecting plate are welded and fixed at the joints. The method has the advantages of being easy to install, good in stress performance, green, convenient and rapid in on-site construction wet-free operation and the like.

Description

technical field [0001] The invention relates to the technical field of prefabricated structure connection in construction engineering, in particular to a dry connection node of prefabricated concrete prefabricated columns and a construction method. Background technique [0002] After years of continuous urbanization in my country, a large number of laborers have poured into the construction industry, making the construction industry flourish. However, the traditional cast-in-place system has increasingly prominent problems of high resource consumption, environmental pollution and excessive energy consumption, which is an inefficient and extensive production method. In order to implement the strategy of sustainable development, in recent years, my country has issued a number of policies to support the application and promotion of prefabricated buildings. The prefabricated building is a building that transfers a large number of on-site operations in the traditional constructi...
