Description

Technical Field

[0001] The utility model relates to the technical field of hangar doors, in particular to a single-node modular connection mechanism and a hangar door thereof. Background Art

[0002] The hangar door is the main door of the hangar for aircraft to pass through. It is a kind of airport ground support equipment. The hangar is a building for aircraft to stay and maintain. The installation of a hangar door can shield and protect the interior of the hangar.

[0003] The main structure of existing hangar doors is divided into two forms:

[0004] One is the on-site welding type, in which the steel sections used for the hangar door are transported to the project site, welded into the main structure on site, and then the power unit, auxiliary unit and decorative parts are added to form a complete hangar door.

[0005] Among them, the power unit is a general term for devices that provide power for the main structure, which can be pneumatic, electric and internal combustion engines and their driven wheel sets; the auxiliary unit is a general term for various systems that enable all equipment on the main structure to work normally, including wires, sensors, locks, communication systems and control systems; decorative parts are a general term for other structures that do not affect the functions of the equipment on the main structure, including glass, panels, frame panels and seals.

[0006] Due to the huge structure of the hangar door, there are many connection nodes between the various profiles, and there are a large number of complex welding points, which cannot be automated. Manual welding is labor-intensive, inefficient, and has poor precision, resulting in long construction periods and unstable project quality.

[0007] The other is the bolt assembly type, in which the installation holes are processed in the factory for the steel sections used for the hangar door, and then the various sections are assembled into the main structure with bolts at the construction site, and then the power unit, auxiliary unit and decorative parts are added to form a complete hangar door.

[0008] This method avoids on-site welding and improves on-site construction efficiency. However, due to the huge structure of the hangar door and the various connection nodes between the profiles, the bolt installation requirements for different nodes are different, which requires the installation technology of on-site workers. If the installation process of each bolt node cannot be well distinguished and identified, it will lead to large overall structural errors.

[0009] In one engineering embodiment, the on-site construction party must have the technicians of the hangar door manufacturer to provide installation guidance to accurately distinguish the unique installation process of each bolt node. This construction feature makes it impossible to modularize this form of hangar door, because in a typical engineering embodiment, the hangar door manufacturer does not always hold the steel structure engineering installation qualification, and is only responsible for shipping the hangar door parts to the site, and the qualified construction party on site is responsible for the installation. The bolt node installation method of the construction party is difficult to fully meet the design preset state of the hangar door manufacturer, resulting in a large hangar door assembly error. The solution is that only by sending personnel from the hangar door manufacturer to the site to guide the installation can the hangar door that meets the design preset be assembled. However, this form of sending personnel is not a typical engineering embodiment. For example, the hangar door exported abroad can only be installed by the on-site construction party or a third party that is not the hangar door manufacturer due to the construction period and personnel visa restrictions. In such engineering embodiments, due to the lack of on-site installation technical support, bolt-assembled hangar doors cannot be used, so the existing bolt-assembled hangar doors are not modular hangar doors, but only a non-modular profile on-site assembly technology.

[0010] Therefore, it is necessary to design a new main structure form of hangar door, all of which have unique installation node forms and simplify the on-site assembly process to one, so as to achieve modularization of hangar doors and their series of products. Utility Model Content

[0011] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a single-node modular connection mechanism and a hangar door thereof, so as to solve the technical problem of complex on-site assembly of the existing hangar door.
