Description

Technical Field

[0001] The present invention relates to the field of civil air defense engineering, and particularly to a detachable and reusable fixture for assisting in the precise positioning and embedding of civil air defense door frames and an application method thereof. Background Art

[0002] A civil air defense door is the door at the entrance of a civil air defense project. As a device connecting the enclosed space of the civil air defense orifice protection project with the outside world, it is an important device for normal personnel passage, personnel evacuation during wartime, reliable entry and exit of personnel during wartime, and intake and exhaust ventilation, etc., and plays a role in protecting the lives of personnel and property such as materials and vehicles.

[0003] Traditional installation method of civil air defense door frames: The method of first embedding the door frame and then installing the door leaf is adopted. In the construction of embedding civil air defense door frames, usually three thick steel bars are cross - set as temporary fixing measures for the door frame. During the concrete pouring process, the door frame often becomes distorted due to factors such as personnel trampling and concrete vibration, and its flatness, perpendicularity, etc. often do not meet the requirements, resulting in the inability to install the door leaf later.

[0004] In addition, there is also the use of a hoisting mechanism for auxiliary fixed installation. For example, a civil air defense door installation frame disclosed in Chinese Patent CN217201682U includes a frame main body and a hoisting mechanism; among them, the frame main body includes a bottom frame, a top beam and two columns. The bottom frame is horizontally installed at the bottom, the two columns are vertically installed on both sides of the bottom frame, and both ends of the top beam are respectively installed on the tops of the two columns; several hoisting mechanisms are provided, including an installation frame, a hoisting pulley assembly and a winch. The installation frame is arranged on the top of the top beam, the installation frame is provided with installation holes for installing the hoisting pulley assembly, the hoisting pulley assembly is used for hanging the civil air defense door, the winch is arranged on the bottom frame, and the winch is connected with the hoisting pulley assembly.

[0005] However, there are still the following defects:

[0072] Please refer to the attached for installation process Figures 13-18 .

[0073] Application of BIM technology: Using BIM technology, we plan and arrange the parameters of the proposed civil air defense door frame and the surrounding structural measures in combination with the design drawings. We arrange the vertical and horizontal center axes of the door lintel of the proposed civil air defense door, and draw out the vertical and horizontal axes and 200mm control lines of the leveling base installation on both sides; draw out the civil air defense door frame installation elevation control points and re-measurement points on the surrounding tied steel bars, draw a simulated installation scene, clearly grasp the installation points, and formulate effective construction processes and control measures.

[0080] Install the vertical adjustment bar system:

[0081] Install the plumb bob crossbar on the vertical poles on both sides of the lintel of the door frame using M16 bolts. Use a level to check the horizontal elevation, tighten the adjusting nuts at the upper and lower ends of the adjusting plate, use a theodolite to correct the verticality of the civil air defense door frame, and tighten the adjusting bolts of the plumb bob crossbar system against the vertical poles on both sides of the lintel of the civil air defense door frame, thus completing the adjustment of the flatness and verticality of the civil air defense door frame, and removing the protection of the lifting hook of the hoisting machinery.

[0082] Concrete pouring:

[0083] ① During the pouring of the foundation slab concrete, special personnel should be assigned to watch over the installation area of the civil air defense door frame, and it is prohibited to perform destructive vibration on the embedded bolts and fixed steel bars of the leveling base system.

[0084] ② Before pouring the upper layer of concrete of the leveling base system (including the vertical structural members on both sides of the civil air defense door frame), the formwork support system should be checked before pouring, and it is prohibited to connect and reinforce with the support vertical pole system, fixed crossbar system, and plumb bob crossbar system.
