Technical Field
The utility model relates to the technical field of tarmac, in particular to a beam-pipe combined tarmac frame structure.
Background
The parking apron with the steel-aluminum mixed structure and the full-aluminum structure is the first choice of the design scheme of the existing high-rise building parking apron due to the characteristics of light weight and low maintenance cost. The frame structure of the steel-aluminum mixed structure parking apron is formed by splicing I-shaped steel, and the full-aluminum structure parking apron frame is formed by splicing I-shaped aluminum. Whether the steel and the aluminum are mixed or the all-aluminum apron frame is paved with strip-shaped aluminum alloy decks, and each deck is connected with an I-beam.
However, the current tarmac framework mainly suffers from two drawbacks:
(1) The lower part of the current parking apron frame structure is mainly connected with the supporting structure through bolts. In the lifting process of the helicopter, the frame structure of the parking apron has certain elastic deformation, so that the I-beam is in rigid contact with the bolts, and fatigue damage is very easy to occur at the bolt connection position;
(2) At present, the parking apron frame is mainly divided into two types, one is a frame structure formed by crisscross I-steel or I-aluminum, and the other scheme is that the frame is formed by combining only I-steel or I-aluminum perpendicular to the direction of a deck. From the analysis of the stress angle of the apron frame, the I-beam vertical to the deck direction is the key for bearing the load of the deck and the helicopter, and the I-beam parallel to the deck direction has smaller stress and mainly aims at stabilizing the whole frame. Thus, the first solution uses i-beams in a direction parallel to the deck, which greatly increases the overall weight of the tarmac frame structure. The second approach eliminates the i-beams parallel to the deck direction, which reduces the stability of the overall frame.
