Y-type connector for new and old structures in added stories of low-storey buildings and construction method thereof

Abstract

The invention provides a Y-shaped connector for new and old structures in added stories of low-storey buildings and a construction method thereof. The two ends of the Y-shaped connector are respectively connected with the two adjacent building structures. The Y-shaped connector is characterized in that the Y-shaped connector comprises a convex part made of steel and a concave part made of steel; the convex part is a convex head connected with a slab seat; the convex head is shaped like dovetail and is similar to Y shape; the Y-shaped convex head extends from the center of the slab seat and isconnected with the slab seat into a whole; the concave part is a groove body connected with the slab seat; the inside of the groove body is shaped like a dovetailed groove corresponding to the Y-shaped convex head; and the groove body extends from the center of the slab seat and is connected with the slab seat into a whole. The Y-shaped connector has the following beneficial effects: the connecting device can fix the displacement and rigidity in the four horizontal directions and can ensure the new and old buildings to mutually slide in the vertical settlement direction, thus ensuring the newand old buildings not to deform during differential settlement and effectively improving the rigidity and aseismatic intensity of the whole building; and the Y-shaped connector can be widely applied to the story adding projects of the new and old buildings.

Description

technical field [0001] The invention relates to a building connecting member, in particular to a connecting piece used between old and new buildings in the engineering structure of adding floors to low-rise buildings. Background technique [0002] With the further deepening of China's reform and opening up, my country's economic and social development is advancing by leaps and bounds and changing with each passing day. The pace of urbanization proposed by the country is growing rapidly. Especially in the first ten years of the 21st century, China's urban development has amazed the world. The modern era has entered China's large and medium-sized cities, and urban high-rise buildings have sprung up like mushrooms. There is less and less land. Due to many reasons of historical development, most of the buildings in the 1980s and 1990s were multi-storey buildings with five or six floors, most of them were brick or brick-concrete structures, and a few of them were frame structur...
