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 c...

Embodiment Construction

[0037] The anti-shock and shock-absorbing design principle of the viscous damper in the present invention is to consume the energy transmitted from the outside according to the viscous resistance generated when the fluid passes through the orifice, reduce the displacement of the building, and reduce the damage of the building structure. During design, the viscous damper 10 is installed between the suspender and the support platform of the shock-absorbing pad, such as figure 1 and figure 2 As shown, the resistance of the damper 10 to the movement absorbs and dissipates the energy generated by the external conditions on the structure, and reduces the transfer of energy between the structure and the support platform of the shock-isolation pad, thereby reducing the damage of the building structure. Ensure the safety of the structure, and prevent the damage of non-structural components, avoid the damage of building interior decoration, indoor equipment and secondary disasters caus...

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...
