Assembled concrete seismic beam-column frame and construction method thereof

Abstract

The invention relates to an assembled concrete seismic beam-column frame. The assembled concrete seismic beam-column frame comprises bracket columns (1), a beam (1), steel strands (4) and anchorage devices (5), wherein the beam (2) is arranged between the two bracket columns (1); a through hole is formed inside the beam (2) along the transverse direction; horizontal through holes corresponding to the beam (2) are formed in the suspended parts and the bodies of the bracket columns (1); the steel strands (4) orderly pass through the through holes inside the bracket columns (1) and the beam (2) and are fixed on the bracket columns (1) at two ends by the anchorage devices (5). The assembled concrete seismic beam-column frame is characterized in that the upper parts of the suspended parts of the bracket columns (1) are shorter than the bottoms; the end faces are of two-step shapes; the connected end faces of the beam (2) and the suspended parts of the bracket columns (1) are of matched two-step shapes. Furthermore, the invention also provides a construction method of the column frame. The method has the advantages that assembling of the beam is facilitated, the integrality of the assembled parts is good, and anti-shear bearing is facilitated.

Description

technical field [0001] The invention belongs to the field of civil and architectural structures, and relates to a reinforced concrete structure, in particular to a prefabricated reinforced concrete assembled anti-seismic frame structure. Background technique [0002] The prefabricated reinforced concrete structure is assembled by prefabricating components at the component preparation stage and transporting them to the project site for assembly. Compared with the cast-in-place reinforced concrete structure, it has the following advantages: the components are mechanized and mass-produced in the factory, with good production conditions, good quality, high efficiency, labor saving, and little impact on the environment and traffic. It can be said that assembly is one of the important development trends of reinforced concrete structures. However, judging from the current use effect, the prefabricated reinforced concrete structure still has shortcomings such as poor integrity and ...
