Construction method for installing viscous damper

Abstract

The invention relates to a construction method for installing a viscous damper. The construction method comprises the following steps of: 1) constructing a lug plate embedded part; 2) preparing before installation of the viscous damper; 3) assembling and disassembling the viscous damper and a wooden box; 4) splicing the viscous damper; 5) locating a lug plate; 6) welding the lug plate; 7) performing flaw detection on a welding line of the lug plate; 8) locating the viscous damper; 9) rechecking the locating of the viscous damper and the lug plate; 10) welding the viscous damper; and 11) treating after the installation of the viscous damper. The method is applicable to installation of massive viscous dampers under the conditions of complicated environment, inconvenient transportation and large dead load of the viscous dampers.

Description

technical field [0001] The invention relates to a damper installation and construction method, in particular to a viscous damper installation and construction method applied in an airport terminal building. Background technique [0002] Natural disasters seriously threaten the safety of building structures, especially the damage caused by earthquakes. How to reduce the damage of natural disasters to building structures has attracted much attention. Under such conditions, the damper came into being. The damper is a kind of anti-shock and shock-absorbing equipment that achieves the purpose of energy absorption and shock absorption by providing movement resistance and consuming movement energy. Since the damper was used in construction projects, the earthquake disaster has been controlled to a certain extent. At the same time, with the continuous development of science and technology, the damper has developed very rapidly, and is constantly improving and perfecting. The viscou...

Problems solved by technology

[0003] In order to improve the anti-seismic capacity of the airport terminal building, the structure in the front central area of ​​the airport terminal building is supported by rubber shock-isolating pads, and the upper concrete structure is completely disconnected from the foundation floor. Displacement, viscous dampers can be installed; however, in large-scale earthquake-isolated buildings, there is no mature construction experience for reference, and the number of viscous dampers installed is large, the environment is complex, transportation is inconvenient, and viscous dampers Since it is heavy, the installation and construction process of the viscous damper must be careful and precise, which is time-consuming and labor-intensive. At the same time, the installation of the viscous damper still has the following difficulties:
