Embodiment Construction

[0071] Examples see figure 1 , figure 2 , image 3 As shown, this construction method for improving the internal force distribution of a large-span even-span hangar, the front of the hangar is the hangar gate 1, including the gate side columns 3 on both sides of the gate and the gate center column 2 in the middle of the gate; The other three sides of the hangar are evenly spaced with support columns and inter-column support structures 8 connected between the support columns, wherein the support columns include rear gable support columns 4 and side wall support columns 5; the roof structure of the hangar includes roof The roof steel structure and the roof enclosure structure, wherein the roof steel structure includes the main frame of the roof and the gate truss 9, and the gate truss 9 is straddled and supported on the gate side column and the gate center column, and the specific steps are as follows:

[0072] Step 1, construct the support column, the side column of the gate...

Abstract

Disclosed is a construction method for improving internal force distribution of a large-span continuous-span hangar. Forced displacement is exerted to a middle supporting seat in the construction process, internal force distribution of a gate truss is adjusted, the internal force peak value at the middle supporting seat is decreased, and the internal force low ebb at the midspan position is filled, so that internal force distribution of the gate truss is more even; and compared with a traditional construction method, the construction method has the following advantages that 1, the internal force peak value of the gate truss is decreased, and type selection of the section of a rod piece tends to be simple; 2, stiffness distribution of a structure system is more balanced and continuous and tends to be even, stiffness mutation is reduced, and seismic performance of the whole structure is improved; 3, technical and economic indicators of the large-span hangar are greatly improved; 4, internal force distribution is even, the material utilization rate is high, and the efficiency of the structure system is greatly improved; 5, the adverse effect on the bearing capacity behavior of a supported roof space truss does not exist; and 6, displacement of the supporting seat is achieved by relying on the self-weight function, and the construction cost is low. The construction method can be widely applied to large-span system construction.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a hangar construction method. Background technique [0002] With the continuous improvement of my country's economic strength, civil aviation transportation has changed from high-end transportation to mass transportation. Under the current hub aviation network system, the aircraft take-off and landing volume of some large aviation hub airports has shown a saturated trend, and large wide-body aircraft can effectively solve the problem of airport congestion, and large wide-body aircraft will surely have a broader market prospect. [0003] At present, the annual order volume of large passenger aircraft in my country is more than 300, and the aircraft maintenance market will usher in a good trend of blowout development. Compared with a single-stand maintenance hangar, a multi-stand hangar has the following characteristics: 1) The aircraft layout is flexible; 2) The hangar sp...
