Embodiment 1
[0080] Such as Figure 18 to Figure 21 As shown, the novel LOFT beam-slab combination system provided by the present invention,
[0081] The system includes Picatinny beam 1, Picatinny plate 2, Picatinny support 3, cement pressure plate 4 and wooden floor 5, the main beam is Picatinny beam 1, and the cross-sectional height of the Picatinny beam h pb Calculate according to formula (1):
[0082]
[0083] Among them, L pb is the span of the Picatinny beam;
[0084] The deflection of the Picatinny beam satisfies the deflection limit:
[0085] f≤[ν] pb ·L pb (Formula 2)
[0086] Calculate the deflection f of the Picatinny beam according to formula (3), when the deflection f is calculated according to the standard value of permanent and variable loads, [ν] pb Take it as 1 / 500; when the deflection f is calculated according to the standard value of permanent load, [v] pb Take it as 1 / 400;
[0087]
[0088] where M pb_max is the maximum mid-span bending moment of the P...
