Installation method of a device capable of releasing internal forces during the installation phase of a steel support

Abstract

The invention relates to a device capable of releasing installation-stage internal force of a steel support and an installation method. The device comprises node connecting plates, a support connecting plate, an internal force releasing mechanism and a support axial deformation mechanism; the node connecting plates are used for being connected with node plates arranged on a main structure; the support connecting plate is connected with the end of the support; the internal releasing mechanism is used for connecting the node connecting plates with the support connecting plates into a whole and releasing loads born by the support in the installation stage through self regulation; the support axial deformation mechanism is arranged in the axial direction of the support connecting plate and used for releasing axial deformation when the support releases the internal force. By adopting the device, the problem that in high-rise steel structure installation, the support needs to bear the loads in the installation stage, so that the support is mainly used for bearing the transverse loads in installation is solved, and not only is the safety of the structure in the installation stage guaranteed, but also the earthquake-proof and wind-resistant efficiency of the support in the usage stage is guaranteed. The device and the installation method can be widely applied to high-rise steel structure installation engineering.

Description

technical field [0001] The invention relates to the technical field of steel structure installation, in particular to an installation method for a device capable of releasing internal force in the installation stage for a steel support. Background technique [0002] In order to improve the lateral stiffness of high-rise building structures and enhance the structure's ability to resist horizontal loads, supports are generally arranged in multiple and high-rise steel structures to form various types of support structure systems, such as setting supports in steel frames to form steel frames- A central support structure, a steel frame-eccentric support structure, or arranging support in the elevator tube or stair tube area of ​​a high-rise building to form a support tube structure. In addition, in order to improve the in-plane stiffness and integrity of the long-span structure, it is also necessary to set up supports or members that play a supporting role in the long-span struct...

AI Technical Summary

Problems solved by technology

For the above connection methods, if the support is installed synchronously or basically synchronously with the main structure, the internal force of the support installation stage cannot be released after the installation is completed; if the support is installed after the main structure is installed, the support cannot bear the wind load during the construction stage, etc.
