T-shaped connector for new and old buildings and construction method thereof

Abstract

The invention relates to a T-shaped connector for new and old buildings and a construction method thereof. The two ends of the T-shaped connector are connected with two adjacent building structures respectively. The T-shaped connector consists of a steel convex part and a steel concave part, wherein the convex part is a raised head connected with a slab base; one end of the slab base is connectedwith the new building structure through a fixed bolt; the raised head has a T shape; the T-shaped raised head is extended out from the center of the slab base and is connected with the slab base to be a whole; the concave part is a recess connected with a slab base; one end of the slab base is connected with the old building structure through a fixed bolt; the shape of the recess corresponds to that of the T-shaped raised head; and the recess is extended out from the center of the slab base and is connected with the slab base to be a whole. The invention provides a connection device, which can fix the displacement and rigidity in four horizontal directions and can make the new and old buildings slide mutually in the settling vertical direction so as to guarantee no deformation of the new and old buildings during differential settlement and effectively improve the rigidity and the anti-seismic intensity of the whole building. The connection device can be widely applied to storey increasing projects of new and old buildings.

Description

technical field [0001] The invention relates to a building connecting member, in particular to a connecting piece used in the construction of adding layers to old and new buildings. Background technique [0002] With the continuous deepening of reform and opening up in the past 30 years, my country's economy and society have developed rapidly, and the pace of urbanization in China has become faster and faster. Especially in recent years, the modern era of cities has arrived, and high-rise buildings have sprung up everywhere. With the continuous development and expansion of cities, land in each urban center has become scarce. Due to historical development, most of the buildings in the 1980s and 1990s were five or six-story, brick or brick-concrete structures, and a few were frame structures, which had poor earthquake resistance and could not meet the needs of modern urban development and human settlements. . Generally, the renovation method of "massive demolition and large ...
