Problems solved by technology

[0004] Usually, when installing the damper, the upper support and the lower support are constructed first, and then the damper is installed on the lower support after the construction of the upper and lower supports is completed. This construction method has many disadvantages. If the upper and lower supports If there is a deviation in the construction of the seat wall, the damper cannot be accurately installed at the predetermined position, and may even cause the damper to be unable to be installed in place. Since there is little research on the installation and construction of the mild steel damper system in the prior art, resulting in The installation and construction of the mild steel damper system is not standardized, and the proper energy dissipation and shock absorption effect cannot be achieved

Embodiment Construction

[0040] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0041] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0042] Such as Figure 1~6 As shown, a top-down installation and construction method of a mild steel energy dissipation damper system includes the following steps:

[0043] ① Bind the 19 structural steel bars of the upper support wall and the main reinforcement of the upper support;

[0044] ②Install the buried plate 1 of the upper support, weld the anchor bars of the buried plate of the upper support with the main reinforcement of the upper support, and weld the upper connecting plate 2 and the buried plate 1 of the upper support;

[0045] ③ Support the upper support wall 19 pouring formwork 3, and set vertical support 4 and horizontal support 5 on the pouring formwork, and set the up...

Abstract

The invention provides a top-down mounting and constructing method of a soft-steel energy-dissipation damper system. The top-down mounting and constructing method includes binding upper bracket wall ribs and mounting an upper bracket embedded plate in advance; erecting and reinforcing an upper bracket wall casting template and casting upper bracket wall concrete; demounting the upper bracket wall casting template after an upper bracket wall is formed; mounting a damper and welding a lower bracket embedded plate on a lower damper connecting plate; binding lower bracket wall ribs, and erecting and reinforcing a lower bracket wall casting template; opening the upper portion of the lower bracket wall, mounting a discharge hopper and casting lower bracket wall concrete; demounting the lower bracket wall casting template after the lower bracket wall is formed. The damper system is mounted from top to bottom, the lower bracket wall can be adjusted slightly after casting of the upper bracket wall, and the problem of failure in damper mounting due to error caused by construction quality is avoided.

Description

technical field [0001] The invention belongs to the construction technical field of anti-seismic systems of construction engineering, and in particular relates to a top-down installation and construction method of a mild steel energy dissipation damper system. Background technique [0002] The traditional method of strengthening the structure against earthquakes is generally to install a large number of shear walls to increase the rigidity and strength of the structure to improve the earthquake resistance of the structure. Such a construction plan not only affects the function of the building, but also greatly increases the difficulty and cost of construction. The application of energy dissipation and shock absorption technology in seismic strengthening has changed the traditional thinking of seismic strengthening, changed "resistance" to "elimination", and opened up a new way of seismic strengthening. The use of mild steel dampers to strengthen the existing buildings before...
