Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a construction process for a steel structure system for a wing-shaped airport terminal building. Background Technology

[0002] The steel structure of an airport terminal refers to the structural system using steel as the main building material in the construction of airport terminals. It is an important component of the terminal building structure and is mainly composed of steel columns, steel beams and other connecting parts. Due to its advantages such as high strength, lightweight and fast construction speed, steel structure has been widely used in the design and construction of modern large public buildings, especially airport terminals.

[0003] Steel structures can create large column-free spaces, making them suitable for buildings like airport terminals that require spacious interiors. For airfoil-shaped steel frame structures, the span is large, and the span gradually decreases from the middle to the sides. Therefore, for steel frame structures with many cross-sectional types, large volume, and varied structures, ensuring the support strength and ease of construction of the steel structure is particularly important. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a wing-shaped airport terminal steel structure system that improves support strength and facilitates construction.

[0005] The above-mentioned technical objective of this invention is achieved through the following technical solution: a steel structure system for a wing-shaped airport terminal, comprising: The transverse trusses are arranged horizontally and side by side, with both ends in the middle pointing downwards in an arch shape; The longitudinal truss is arranged longitudinally between the transverse trusses. The longitudinal truss is divided into one beam, two beams, three beams and four beams. The three beams and four beams are arranged alternately in the middle large span position of the longitudinal truss, the one beams and three beams are arranged alternately in the small span positions on both sides, and the two beams are arranged in the middle and the connection position on both sides. Side beams are arranged around the longitudinal truss; A V-shaped support beam is positioned below the side beam and spans between the connection points of the large and small spans of the longitudinal truss.

[0006] In a preferred embodiment, the present invention can be further configured such that the four beams in the longitudinal truss are bent downwards from back to front, and the lowest end of the beam is raised upwards.

[0007] In a preferred embodiment, the present invention can be further configured such that the three beams in the longitudinal truss are bent downwards from back to front, and the lowest end is raised upwards, with steel columns vertically arranged between each adjacent steel frame and at the lowest end.

[0008] Another objective of this invention is to provide a construction process for a steel structure system for a wing-shaped airport terminal, which improves support strength and facilitates construction.

[0009] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a construction process for a steel structure system of a wing-shaped airport terminal, comprising the following steps: S1, first hoist and install the first section of steel column, then hoist and install the second section of steel column, and then hoist the steel platform of the room-in-room; S2, transport the transverse and longitudinal trusses to the site in sections for assembly, and then install the supporting frame around them; S3, hoisting the longitudinal trusses on the first and third axes; S4, hoist the secondary truss in the east-west transverse truss between the first and third axes, and hoist the second axis unsupported longitudinal truss in three sections; S5, hoist the main truss in the cantilevered transverse truss on the east side of the first axis, and then hoist the secondary truss in the cantilevered transverse truss on the east side of the first axis. S6, hoist the remaining secondary trusses, tie rods, side beams and tie rods in the transverse truss between the first and third axes; S7, hoist the longitudinal truss on the fifth axis; S8, hoist the cantilever sections on the south and north sides of the longitudinal truss on the fifth axis; S9, hoist one section of the longitudinal truss on the seventh axis, and then hoist the other two sections of the longitudinal truss on the seventh axis; S10, hoist the secondary truss in the east-west transverse truss between the third and seventh axes; S11, hoisting the middle section of the unsupported longitudinal truss of the fourth and sixth axes; S12, hoist the cantilevered sections at both ends of the unsupported longitudinal trusses of the fourth and sixth axes; S13, hoist the remaining secondary trusses, tie rods, side beams and tie rods in the transverse truss between the third and seventh axes; S14, hoist one section of the longitudinal truss on the ninth axis, then hoist the second section of the longitudinal truss on the ninth axis, and finally hoist the third section of the longitudinal truss on the ninth axis. S15, hoist the secondary truss in the east-west transverse truss between the seventh and ninth axes; S16, hoist the second and third sections of the unsupported longitudinal truss on the eighth axis, and then hoist the first and fourth sections of the unsupported longitudinal truss on the eighth axis. S17, hoist one section of the longitudinal truss on the eleventh axis, then hoist the second section of the longitudinal truss on the eleventh axis, and finally hoist the third section of the longitudinal truss on the eleventh axis. S18, hoisting the secondary truss in the east-west transverse truss between the ninth and eleventh axes; S19, hoist the second and third sections of the unsupported longitudinal truss on the tenth axis, and then hoist the first and fourth sections of the unsupported longitudinal truss on the tenth axis. S20, hoisting the remaining secondary trusses, tie rods, side beams and tie rods in the transverse truss between the seventh and eleventh axes; S21, the construction of the first to eleventh axes is completed. The second half will be hoisted and completed in the same order. S22, hoist the V-shaped support beam; S23, Remove the support frame.

[0010] In a preferred embodiment, the present invention can be further configured as follows: In step S22, when the V-shaped support beam is hoisted, the V-shaped support beam is divided into five sections from one end to the other, namely one, two, three, four, and five. The connecting sections at both ends that are connected to the side beams are six and seven, respectively, so that the V-shaped support beam is divided into seven large sections for hoisting. A support frame is erected at the middle joint for the jointing operation. During hoisting, the middle support section is hoisted first, and then the connecting sections at the left and right ends that are connected to the side beams are hoisted. The hoisting sequence is three-two-four-one-six-five-seven. After the overall hoisting is completed, it is corrected, and after it is correct, welding is performed.

[0011] In summary, the present invention has the following beneficial effects: 1. By setting up segmented transverse and longitudinal trusses, the trusses can be hoisted in segments, and steel columns are arranged at intervals on the longitudinal trusses. This not only provides stable support for the entire steel structure, but also provides a spacious interior space. In steel structure frames with multiple cross-sectional types, large volume, and varied structures, this effectively ensures the support strength of the steel structure and improves the convenience of construction. 2. By setting up segmented horizontal and vertical trusses for hoisting and adopting a step-by-step installation method, the horizontal and vertical trusses can be hoisted quickly, ensuring stability during construction and achieving convenient and efficient construction.

[0015] like Figure 1 , Figure 2 As shown, a steel structure system for a wing-shaped airport terminal building includes a transverse truss 1, a longitudinal truss 2, a side beam 3, and a V-shaped support beam 4.

[0016] like Figure 1 , Figure 2 As shown, the transverse trusses 1 are arranged horizontally and side by side, with both ends at the middle position pointing downwards in an arched shape. The transverse trusses 1 are installed in segments and are located between adjacent longitudinal trusses 2.

[0017] like Figure 3 , Figure 4 As shown, the longitudinal truss 2 is longitudinally arranged between the transverse trusses 1.

In steel structure frames with multiple cross-sectional types, large volume and varied structure, the support strength of the steel structure is effectively guaranteed and the construction convenience is improved.

[0042] S22, hoist the V-shaped support beam 4. Divide the V-shaped support beam 4 into five sections from one end to the other, namely one, two, three, four, and five. The connecting sections at both ends that connect to the side beam 3 are six and seven, respectively. This makes the V-shaped support beam 4 divided into seven large sections for hoisting. A support frame is erected at the middle joint for the connection operation. During hoisting, the middle support section is hoisted first, followed by the connecting sections at the left and right ends that connect to the side beam 3.
