Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that due to the influence of the positions of multiple gate columns, the vacant area between two adjacent large wide-body aircraft cannot be effectively utilized, for example, narrow-body passenger aircraft maintenance machines cannot be interspersed. place, directly lead to the need to invest a lot of manpower and material resources to build more hangars

Embodiment 1

[0054] refer to figure 1 , Take a large-span maintenance hangar with a span of 405m, a width of 100m and an aspect ratio of more than 3 as an example. The large-span maintenance hangar truss system includes roof support column 1, roof steel structure 2, gate truss 3 and L Type lattice column 4. The side of the hangar facing the apron is open, and the open side is equipped with an electric sliding door that bears the lower load and guides upward. The steel structure of the roof in the hangar 2 suspension equipment systems, radiant heating, fire sprinkler and other electromechanical equipment systems and their related Matching maintenance walkway system.

[0055] refer to figure 1 and figure 2 The roof support column 1 includes a side wall support column 10, a rear gable support column 11, a wind resistance column 12 and a compression rod 13, which are arranged at intervals along the three sides of the hangar. The wind resistance column 12 is inserted between two adjacent s...

Embodiment 2

[0065] refer to Figure 7 The difference between this embodiment and Embodiment 1 is that, in order to slow down the vibration transmitted by the inclined truss 22 to the four-limb lattice columns 40, a connecting mechanism is also installed between the inclined truss 22 and the four-limb lattice columns 40. The connecting mechanism It includes a support plate 5 , a horizontal insertion cylinder 6 , a turntable 7 and a vertical insertion cylinder 8 .

[0066] There are four guide cylinders 50 on the top of the support plate 5 and four horizontal insertion cylinders 6. The guide cylinders 50 have a cylindrical structure with openings at both ends, and the horizontal insertion cylinder 6 is a cylinder structure with one end open. The open end of the guide cylinder 50 faces the guide cylinder 50 , and a reinforcing rod 51 is welded between the adjacent two guide cylinders 50 , the two adjacent horizontal insertion cylinders 6 , and the adjacent guide cylinders 50 and the horizont...

Embodiment 3

[0075] refer to Figure 11 and Figure 12 The difference between this embodiment and Embodiment 2 is that a hole plugging device 9 is provided in the slurry storage cavity 620, and the hole plugging device 9 includes a main cylinder 90, which is coaxially arranged with the horizontal insertion cylinder 6, A secondary cylinder 91 is vertically fixed at the end of the main cylinder 90 away from the limiting cylinder 60 . The secondary cylinder 91 includes five sub-cylinders and is in the shape of a five-pointed star. The connection point between the main cylinder 90 and the secondary cylinder 91 is located in the secondary cylinder. At the center of the cylinder 91 , a support rod 910 for supporting the secondary cylinder 91 is fixed between the side of the secondary cylinder 91 away from the main cylinder 90 and the closed end of the horizontal insertion cylinder 6 . A plugging cylinder 92 is slidably and sealedly connected in each auxiliary cylinder 91 .

Abstract

The present application relates to a large-span maintenance hangar truss system and its L-shaped lattice columns, including roof support columns, roof steel structures, gate trusses and L-shaped lattice columns. The roof support columns include side wall support columns and The rear gable support column, the side wall support column include inclined truss side wall support column, the roof steel structure includes the main structure frame and a plurality of inclined trusses, and the multiple inclined trusses are horizontally inclined along the length of the hangar; only the lower part of the gate truss is installed There is a central column of the gate, the L-shaped lattice column is arranged in the hangar, a gap is set between the L-shaped lattice column and the rear gable, and at least one L-shaped lattice is arranged between the adjacent central column of the gate and the supporting column of the side wall Column, one end of the inclined truss located on the side is erected on the support column of the inclined truss side wall, the other end is erected on the L-shaped lattice column, one end of the inclined truss in the middle is erected on the central column of the gate, and the other end is erected on the L-shaped lattice. on the pillar. The present application has the effect of making full use of the vacant space inside the large-span maintenance hangar to reduce the input cost.

Description

technical field [0001] The present application relates to the field of hangars, in particular to a large-span maintenance hangar truss system and its L-shaped lattice columns. Background technique [0002] With the continuous improvement of my country's economic strength, civil aviation transportation has been transformed from high-end transportation to mass transportation, and the number of passenger aircraft orders has increased year by year, which has higher requirements for the maintenance capabilities of domestic civil airports. At present, my country's maintenance hangars are divided into single-machine maintenance hangars and multi-machine maintenance hangars, and multi-machine maintenance hangars have far-reaching development prospects. [0003] Compared with the stand-alone maintenance hangar, the multi-machine maintenance hangar has many advantages, such as: flexible aircraft layout; high utilization rate of hangar space, the vacant space between two large wide-bod...
