Drawing resistance device for additionally-mounted elevator in existing building

Abstract

The invention relates to a drawing resistance device for an additionally-mounted elevator in an existing building, and belongs to the field of building reconstruction and earthquake-resistant measures. The drawing resistance device mainly comprises the existing building, bolts, a steel cushion plate, compression springs, high-strength springs, connecting beams, a buffering rubber body, a steel bracket and a flat spring. The steel cushion plate and the existing building are fixed through the bolts, and the compression springs and the high-strength springs are arranged on the side, away from theexisting building, of the steel cushion plate; the steel cushion plate is connected with the compression springs, the other sides of the compression springs are connected with the connecting beams, the steel cushion plate is connected with the high-strength springs as well, and the other sides of the high-strength springs are connected with the buffering rubber body; and the buffering rubber bodyis fixed to the connecting beams through the bolts, the steel bracket is arranged on the other side, away from the high-strength springs, of the buffering rubber body, and the flat spring is arrangedin the middle of the steel bracket. The drawing resistance device is easy to construct and low in construction cost; and industrial splitting is quite convenient, the drawing resistance device is convenient to produce and easy to mount and is a prefabricated member, and the industrialization process is propelled advantageously.

Description

technical field [0001] The invention belongs to the field of anti-seismic measures for building renovation, in particular to an anti-drawing device for an elevator installed in an existing building. Background technique [0002] With the acceleration of my country's urbanization process, my country's construction industry has developed very rapidly. At present, the total area of ​​existing buildings in the country is nearly 50 billion square meters. Due to backward building functions and insufficient safety, a large number of existing buildings can no longer meet the needs of modern development. Especially Most of the buildings built before 1990 cannot meet the seismic performance requirements of the current norms. At the same time, a large number of existing buildings are non-energy-saving buildings and urgently need energy-saving renovation. [0003] The housing construction in our country has gradually entered from the economical type in the early 1980s to the well-off typ...
