Connecting joint of prefabricated steel reinforced concrete column and reinforced concrete beam and construction process thereof

Abstract

The invention discloses a connecting joint of a prefabricated steel reinforced concrete column and a reinforced concrete beam and a construction process thereof, and belongs to the technical field ofconstructional engineering. The connecting joint comprises the prefabricated steel reinforced concrete column and a prefabricated reinforced concrete beam. Longitudinal profile steel and transverse profile steel are arranged in the prefabricated steel reinforced concrete column. One end of the transverse profile steel is connected with the longitudinal profile steel, and the other end of the transverse profile steel is fixedly connected with a first connecting piece. An embedded piece is arranged at one end of the prefabricated reinforced concrete beam. The embedded piece is an embedded steelpipe, embedded profile steel or an embedded anchor bar. A second connecting piece is fixedly connected to the end, close to the prefabricated steel reinforced concrete column, of the embedded piece. The first connecting piece is connected with the second connecting piece through a bolt so that the prefabricated steel reinforced concrete column can be connected with the prefabricated reinforced concrete beam. According to the connecting joint of the prefabricated steel reinforced concrete column and reinforced concrete beam and the construction process thereof, the structural strength and ductility are improved, the construction speed is high, and environmental protection and economy are achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a connection node between a prefabricated steel concrete column and a reinforced concrete beam and a construction process thereof. Background technique [0002] The reinforced concrete frame structure has good seismic performance, which makes this structure widely used. In the frame structure, the nodes are the key parts connecting columns and beams, which play the role of transmitting and redistributing internal forces and ensuring the integrity of the structure. It is safe and reliable. The nodes can guarantee the normal operation of the structure. However, the reinforced concrete frame joints have weak shear capacity and poor seismic performance. In order to improve the strength and ductility of joints, reinforced concrete columns are used instead of reinforced concrete columns to form joints with reinforced concrete beams. [0003] The reinforced concrete s...

Problems solved by technology

The construction of cast-in-place concrete requires a large number of formwork, a large amount of on-site work, a long construction period, and the construction quality cannot be guaranteed. It not only consumes a lot of energy, but also causes damage to the surrounding environment.
