Description

Civil air defense door frame mounting support structure

Technical Field

The utility model belongs to the technical field of civil air defense engineering, and particularly relates to a civil air defense door frame mounting and supporting structure.

Background

The installation quality of the civil air defense door frame has great influence on the protection sealing performance of the civil air defense door, and because the civil air defense door frame and the concrete door frame wall are cast synchronously and integrally, the correction difficulty is high after the problem occurs, and some of the civil air defense door frame cannot be corrected, so that permanent quality defects are formed for engineering. And the installation quality of the door frame is closely related to the erection of the supporting structure of the door frame installation. After the door frame is vertically installed, a door frame supporting structure is erected, and the door frame is temporarily fixed. The quality of the design and installation of the door frame supporting system directly influences the installation quality of the door frame. The existing civil air defense door frame is generally installed by directly welding steel pipes into a supporting structure, if the perpendicularity measured after welding is not satisfied, part of the supporting structure is required to be removed, and the steel pipes are welded again after adjustment, thus the labor and the effort are wasted.
