Abstract
The present invention provides a concrete foundation for a high-storey building, which has the advantages of reasonable structure stress and low cost. The concrete foundation comprises a plurality of upright posts (1), wherein the bottom ends of the adjacent upright posts are connected by arch-shaped components (5) which are curved concrete components which downwards protrudes; besides, a structure bottom board (2) is formed at the bottom ends of the upright posts and above the arch-shaped components and is supported by a plurality of structure beams (3) respectively connected to the position between each upright post and the adjacent upright post.
Description
Technical field of the present invention
The present invention relates to high-rise building, particularly the foundation structure used of High level Framework building.
Background technology
In the past, the basis that high-rise building is used generally comprises two types, a kind of is mat foundation, it is certain thickness by having, the whole armored concrete slab of large tracts of land that supports whole building forms, it is softer that this mat foundation is suitable for soil property, the basis, bearing capacity of foundation soil is lower, superstructure is delivered to the situation of the very big and superstructure of load on basis to the uneven settlement of foundation sensitivity, because its loaded area is bigger, so can lower base pressure, improve bearing capacity of foundation soil, increase the integral rigidity on basis, and adjustment differential settlement, but for such basis, when high-rise building higher, such as super high rise building, be that upper load is when big, particularly satisfy the requirement that the anti-impact of suspension column place plate is cut, must increase the thickness of whole concrete slab, make the thickness of whole foundation slab very big like this, and in fact from loading angle, other zone except the suspension column position in the plate does not participate in resisting the shearing of post to plate substantially, the thickness of these other regional plate is excessive, and therefore from force structure, above-mentioned mat foundation is to have utilized concrete weakness, be that relatively poor shear resistance (shear strength is lower) is resisted the superstructure load, rather than utilize concrete advantage, promptly stronger crushing resistance (compressive strength is higher) to resist the superstructure load, this shows, this mat foundation is not rational stress system, and it can cause the waste on the material.The basis of another kind of type is a box foundation, the steel concrete mass-type foundation of the box-shaped that it is made up of the internal partition wall of base plate, top board, side wall and some, this basis has the higher rigidity of structure and globality, being suitable for the superstructure load differs greatly, to the differential settlement sensitivity, the high-rise building of shockproof requirements strictness, but the underground excavation on such basis is bigger, and the expense of the structure that goes up above Ground far away in underground expense of constructing, therefore the cost of this box foundation is very high.
Content of the present invention
