Problems solved by technology

[0012] The purpose of the present invention is to provide a large-scale wide-body aircraft multi-position maintenance hangar roof slanted truss structure system, to solve the structural quality of the existing hangar steel truss structure system in the large-scale wide-body aircraft multi-position maintenance hangar Uneven distribution leads to poor seismic performance of the structural system, poor technical and economic indicators of the gate trusses, too large single-span spans in ultra-low airspace and height-limited sites, difficulty in realizing single-span hangar spans, and even-span hangar gate openings Poor collapse resistance of side and center columns, long system load transmission route, excessive internal force of gate truss members, and difficult cross-section selection

Embodiment 1

[0060] Embodiment one sees Figure 6-10 As shown, the hangar is a single-span hangar. This large-scale wide-body passenger aircraft multi-stand maintenance hangar roof oblique truss structure system includes roof support columns arranged at intervals along the three sides of the hangar and fixed on the roof support columns. The roof steel structure at the top of the column; it also includes a gate truss support column arranged along the open side of the hangar and a gate truss 2 fixed on the top of the gate truss support column, and the roof steel structure is connected with the gate truss 2 .

[0061] The roof steel structure includes a main structural frame 3 covering the hangar, and also includes a diagonal truss 4 and a straight truss 5 arranged inside the main structural frame. It can be formed by truss members replacing the corresponding positions of the main structural members, and the straight truss 5 intersects with the oblique truss 4 . In this embodiment, the incli...

Embodiment 2

[0069] Embodiment two see Figure 11-16 As shown in , 18, the hangar is a two-span hangar, so different from Embodiment 1, the gate truss support column also includes the gate truss middle support column 8 set at the sub-span of the multi-span hangar. There is at least one oblique truss 4 at the sub-span. In this embodiment, there are two. One end of the two oblique trusses is connected as a whole and placed on the supporting column 8 of the gate truss. The other end of the two oblique trusses The parts are all supported and connected to the gable support column 7a behind the oblique truss. The angle between the oblique truss 4 and the gate truss 2 can be set to 30-60 degrees according to the stress situation, wherein 45 degrees is the optimal stress angle, which is 45 degrees in this embodiment. So far, the inclined trusses installed in each span of the hangar are arranged in two V-shaped, two mirror-symmetrical arrangements, and four in a W-shape.

Abstract

A large wide airliner multi-position maintenance hangar roof diagonal truss structural system comprises roof bearing columns arranged along three edges of a hangar at intervals and a roof steel structure fixed to the tops of the roof bearing columns and further comprises gate truss bearing columns arranged along the open edge of the hangar and a gate truss fixed to the tops of the gate truss bearing columns. The roof steel structure is connected with the gate truss, the hangar comprises a single-span hangar body and a multi-span hangar body, the roof steel structure comprises a main structural frame covering the hangar and further comprises a diagonal truss and a linear truss which are arranged in the main structure frame, and the linear truss intersects with the diagonal truss. Based on the shortest transfer path theory of force, the diagonal truss and the linear truss are arranged in the hangar, a roof is divided and surrounded, the pressure of the gate truss is effectively relieved, and it is possible to implement the ultralow-airspace height-limited-place ultra-large-span multi-position maintenance hangar.

Description

technical field [0001] The invention relates to a steel truss structure system of a hangar, in particular to a slanted truss structure system of the roof of a multi-machine maintenance hangar for a wide-body passenger aircraft. 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. my country's economic development data in the past 20 years shows that for every 1% increase in GDP, civil aviation passenger volume increases by 1.58%, and cargo volume increases by 1.34%; for every 1% increase in the number of tourists, passenger volume increases by 1.36%; Freight traffic increased by 0.87%; for every 1% increase in urban population, passenger traffic increased by 2.86%. Under the current hub aviation network system, the aircraft take-off and landing volume of some large aviation hub airports in the world has shown a saturated trend, and large ...
