Detailed Description
The invention is further explained below with reference to the drawings:
referring to fig. 1 to 2, an embodiment of a platform structure for high-rise buildings includes a support structure 1 and a platform plate 2, where the support structure 1 includes vertical frame columns 11 distributed in a square grid shape on a horizontal plane, and a square grid-shaped support layer 12 composed of frame beams 120 horizontally erected between two adjacent frame columns 11; the number of the frame columns 11 is distributed at intervals according to the area of the platform structure, each row is aligned with each column, and the span distance is based on the economic span; the frame beams 120 are supported between the frame columns 11 in two orthogonal directions, so that 2-4 frame beams 120 are transversely supported at the same height position of each support column. The supporting structure 1 is provided with a plurality of groups of supporting layers 12 arranged at intervals along the height direction, and the frame columns 11 and the supporting layers 12 are of concrete frame structures; a plurality of buckling restrained braces 3 distributed along two orthogonal directions of a horizontal plane are arranged between the supporting layers 12, that is, at least two groups of buckling restrained braces 3 in mutually perpendicular directions are arranged in the same layer of the platform structure to resist torsion from different directions, and the structural principle of the buckling restrained braces 3 is the conventional technology and is not described in detail; and the buckling restrained braces 3 between the supporting layers 12 are consistent in vertical position and specification, that is, the buckling restrained braces 3 between each layer of the platform structure are in one-to-one correspondence in position, and the buckling restrained braces 3 at the same vertical position are consistent in specification.
In this embodiment, be the frame post 11 of square latticed distribution for the top of bearing structure 1 forms a large amount of strong points of even distribution, for landing slab 2 provides even holding power, and not only bearing capacity is strong, because landing slab 2 need not to improve the support strength of self unsettled part through the structure just in a large number moreover, consequently can save landing slab 2 in a large number with the steel volume. Meanwhile, the whole supporting structure 1 is a concrete frame structure without a floor slab, and compared with a huge steel supporting cylinder or concrete supporting cylinder structure, the construction cost of the platform structure is greatly reduced. When the top of the platform structure is provided with an inclined plate or structures such as a corridor and a slide way, the platform can be seriously twisted, and the buckling restrained braces 3 are arranged on the two sides of the supporting structure 1, so that the twisting effect caused by uneven load can be reduced. When the earthquake intensity is high, the buckling restrained brace 3 enters a buckling state, and stable and reliable hysteretic energy consumption is realized through the buckling restrained brace 3, so that the damage degree of the supporting structure 1 is reduced, the bearing safety of the supporting structure 1 is ensured, and the shock resistance of the platform structure is improved. As the buckling restrained braces 3 on each layer are consistent in vertical position and specification, and most of the weight of the platform structure is on the upper part of the platform, the vertical change of the support structure 1 containing the buckling restrained braces 3 under the action of an earthquake is small, the buckling restrained braces 3 of the same frame tend to be synchronous along the vertical yielding, the transmission of horizontal force in a plane can be effectively avoided, and the complexity of the structure is reduced.
In a preferred embodiment, each buckling-restrained brace 3 is distributed around four outer circumferential surfaces of the supporting structure 1, i.e. buckling-restrained braces 3 are distributed on the outer side of the supporting structure 1, which represents only a relative position, i.e. a position located on the outer side of the supporting structure 1, and is not limited to an absolute outer side.
In this embodiment, since the buckling-restrained brace 3 is disposed on the outer side of the supporting structure 1, the torsional rigidity is stronger than that of the buckling-restrained brace distributed on the inner side of the supporting structure 1, and the torsional rigidity of the platform structure can be further improved.
In a preferred embodiment, the frame columns 11 have a span of 6-10 m.
In this embodiment, the span distance is a compromise between structural reliability and economy.
In a preferred embodiment, the spacing height of the supporting layers 12 is 4-6 m.
In this embodiment, the span distance enables the frame beam 120 to support the frame column 11, thereby reducing the cross-sectional area of the frame column 11 and facilitating the construction.
The above description is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
