Energy dissipation type coupled anti-seismic wall with reinforcing bars, grouting holes, building blocks and combined coupling beam and manufacturing method

Abstract

The invention belongs to the technical field of earthquake resistance of building structures, and particularly relates to an energy dissipation type coupled anti-seismic wall with reinforcing bars, grouting holes, building blocks and a combined coupling beam and a manufacturing method. The energy dissipation type coupled anti-seismic wall is adopted by a bearing wall of a multi-storey building in a town. The energy dissipation type coupled anti-seismic wall comprises a building block wall body, a coupling beam, soft steel dampers, single-reinforcement core columns, construction core columns and horizontal pull connecting ribs. According to the invention, due to the combined action of the core columns and the horizontal pull connecting ribs, the building block wall body is effectively constrained, and the integrity and the anti-seismic performance of a coupling wall column are improved. The coupling beam and a constraint building block wall beam on the top of the coupling beam are combined to form the shear type combined coupling beam, and the soft steel dampers are arranged on the portions of connection between the coupling beam and the coupling wall column, so that multiple energy dissipation and seismic resistance defense lines of the coupled anti-seismic wall are formed, and the ductility and the energy dissipation capacity of the wall body are enhanced.

Description

technical field [0001] The invention belongs to the field of anti-seismic technology of building structures, in particular to a load-bearing wall of multi-storey buildings in villages and towns, which adopts a composite joint beam energy dissipation type anti-seismic wall with reinforced grouting blocks and a manufacturing method thereof. Background technique [0002] In recent years, most of the major earthquakes occurred in rural areas, such as the Wenchuan Earthquake in 2008, the Yushu Earthquake in 2010, the Lushan Earthquake in 2013, the Zhangxian Earthquake in Min County in 2013, and the Ludian Earthquake in 2014, which caused serious casualties and Economic losses. What deserves special attention is that most of my country's seismic belts are currently in an active period, and destructive earthquakes are gradually showing a trend of high frequency and frequent occurrence. According to the survey, masonry structures account for more than 60% of the structural forms of...
