Technical Field

The utility model relates to a building structure design field especially relates to concrete shell building.

Background

In recent decades, with the innovative requirements of Chinese architectural design in the field of large-span spatial structures, the spatial structure form of the steel structure has been widely and generally applied. With the development of society and the progress of building technology, people have demanded more than basic requirements of life and production, but have demanded more advanced requirements on buildings, namely novel and unique forms and remarkable pursuit, one of which is the demand on building materials, so that the building form with a large span concrete thin-shell structure which prevails in the middle of the last century is mentioned again.

The concrete space thin-shell structure is favored by architects because of having a rough and simple material mechanism and stronger bearing capacity, but the traditional design method of the building comprising the concrete thin-shell structure generally comprises the step of connecting and covering the concrete thin-shell structure on a supporting structure below the concrete thin-shell structure, and the concrete thin-shell structure is usually heavier, so that on one hand, the concrete space thin-shell structure is easily influenced by seismic waves transmitted from the supporting structure to bear horizontal load and further generate large horizontal shaking during earthquake, has the risk of separation from the supporting structure, cannot play a role in stabilizing enclosure, and is difficult to meet the requirement of earthquake-proof design; on the other hand, when the heavy-load concrete thin-shell structure transmits force downwards, the part connected with the bottom supporting structure is easy to have large stress concentration, the potential safety hazard is large, the reliability is poor, and the current higher anti-seismic standard cannot be met. For the above reasons, the design form of the concrete shell structure cannot be too large to be applied to a large building structure.

As shown in fig. 1 and 2, in an embodiment of the present invention, a concrete shell building is provided, including:

a support structure 100;

a thin-shell structure 200 including a prestressed girder 210 and a shell 220 disposed on the prestressed girder 210, wherein an end of the prestressed girder 210 is lapped on a top edge of the support structure 100;

the buffering and limiting structure 300 comprises a plurality of shock-isolating support bodies 310 which are distributed between the prestressed beam 210 and the supporting structure 100, and the shock-isolating support bodies 310 are respectively connected with the prestressed beam 210 and the supporting structure 100.

The large-area thin-shell structure 200 of the embodiment can uniformly distribute the applied pressure to each part of the roof and transmit the pressure to the prestressed beams 210 by fully utilizing the material characteristics, and then transmit the pressure to the supporting structure 100 through the distributed buffering and limiting structures 300.

In this embodiment, on one hand, the distributed buffering and limiting structures 300 can deform and absorb seismic waves and reduce the action of the seismic waves from below, so as to reduce the influence of the seismic waves and the horizontal load on the upper thin-shell structure 200 in a balanced manner, reduce the horizontal shaking and have strong stability, and reduce the risk of separation, and when the prestressed beam 210 moves horizontally relative to the supporting structure 100, the buffering and limiting structures 300 can horizontally dislocate and deform and absorb energy, so as to limit the relative movement distance between the prestressed beam 210 and the supporting structure 100, thereby improving the horizontal stability; on the other hand, when the concrete shell structure 200 bears the load, the pressure borne by the concrete shell structure is uniformly distributed to each part of the roof and is transmitted to the prestressed beams 210, then the force is synchronously buffered and transmitted downwards through the plurality of shock-insulation support bodies 310 distributed between the prestressed beams 210 and the supporting structure 100, the shock-insulation support bodies 310 can be distributed at the positions A-T in the figure 2, the prestressed beams 210 and the shock-insulation support bodies 310 can sequentially buffer the stress, the stress concentration possibly occurring at the connecting part of the concrete shell structure 200 is reduced after the load is released, the reliability of node design is further improved, and the force distribution in the structure is improved. By the high-position shock insulation effect, the adverse effect of the large-span concrete thin-shell structure 200 on the structure due to the overlarge self weight can be greatly reduced.

In the embodiment, the high-level vibration isolation support and the thin-shell structure 200 are mixed and applied, the self-weight problem of the large-span concrete structure is not avoided in high-intensity areas, and the design view of architects is expanded. After the technology is adopted, a large-size concrete space thin shell can be designed on a large building structure, for example, an ultra-large thin shell structure 200 with the longitudinal length of 58.8m and the transverse length of 32.6m is designed in fig. 2, and the advantage of large body shape of the concrete thin shell structure 200 is fully exerted to form a building with peculiar and novel shape and suitable for various planes; the large-area concrete thin-shell structure 200 can make full use of the material characteristics to uniformly distribute the pressure to each part of the roof and transfer the load downwards through the prestressed beams 210 and the buffering limiting structure 300, has strong bearing capacity and good effect, and can form stable enclosure with large area in space, thereby combining the functions of bearing and enclosure into a whole and exerting the advantages of the concrete thin-shell structure to the maximum.

Under the action of an extremely strong earthquake, the thin-shell structure bears stronger horizontal load under the action of the earthquake, and the risk of the thin-shell structure falling off from the supporting structure is further increased, so, referring to fig. 2 and 3, in some embodiments, at least two of the shock-insulation support bodies 310 are provided with a limiting component so that the shock-insulation support bodies 310 form a limiting support 320, the limiting component comprises a longitudinal limiter 311 and a transverse limiter 312 which are arranged on the side of the shock-insulation support body 310, for example, a limiting component can be arranged on the shock-insulation support body 310 at B, I, L, S so as to form the limiting support 320. The direction of the longitudinal stopper 311 of one of the stopper supports 320 is opposite to the direction of the longitudinal stopper 311 of at least one other of the stopper supports 320, for example, the direction of the longitudinal stopper 311 of the stopper support 320 at the L position in fig. 2 is opposite to the direction of the longitudinal stopper 311 of the stopper support 320 at the B, S position. Lateral stopper 312 of one of stopper brackets 320 is opposite to the direction of the restriction of lateral stopper 312 of at least one other of stopper brackets 320, for example, the direction of the restriction of lateral stopper 312 of stopper bracket 320 at the L position in fig. 2 is opposite to the direction of the restriction of lateral stopper 312 of stopper bracket 320 at the B, I position.

Specifically, the position where the prestressed beam 210 is connected to the support structure 100 is provided with more than two limiting supports 320, the longitudinal limiter 311 and the transverse limiter 312 can limit the thin-shell structure 200 from the longitudinal direction and the transverse direction, respectively, and the limiting directions of the longitudinal limiters 311 of the two limiting supports 320 are opposite to each other, and the limiting directions of the transverse limiters 312 of the two limiting supports 320 are opposite to each other, so that the thin-shell structure 200 can be effectively limited forcibly from all directions in a plane, the thin-shell structure 200 can be prevented from moving in any possible direction due to the overall forced limitation, and the method is more stable and reliable, and reduces the risk that the thin-shell structure 200 falls off from the support structure 100.

Referring to fig. 2, in some embodiments, the limiting brackets 320 are distributed between the frame of the supporting structure 100 and the prestressed beam 210 in both longitudinal and transverse directions; the limiting directions of the transverse limiters 312 of the two limiting supports 320 which are distributed transversely are opposite, and the limiting directions of the longitudinal limiters 311 of the two limiting supports 320 which are distributed longitudinally are opposite.

In this embodiment, the whole buffering limiting structure 300 is used for limiting the thin-shell structure 200 in a balanced and symmetrical manner in the longitudinal and transverse directions, so that the thin-shell structure 200 can be limited in a balanced manner in the process of reciprocating vibration caused by an earthquake, the thin-shell structure 200 is prevented from rotating or shifting in the horizontal plane when the earthquake occurs due to the asymmetric limiting position, and the relative position and the relative form stability of the thin-shell structure 200 and the supporting structure 100 are ensured.

Specifically, when the shell structure 200 moves in the longitudinal direction, the longitudinal position-limiting portion 311a on the upper surface of the supporting structure 100 contacts with the longitudinal position-limiting portion 311a on the lower surface of the prestressed beam 210 to block the longitudinal movement of the shell structure 200; when the thin-shell structure 200 moves in the lateral direction, the lateral position-limiting portion 312a of the upper surface of the supporting structure 100 blocks the movement of the thin-shell structure 200 in the lateral direction by contacting with the lateral position-limiting portion 312a of the lower surface of the prestressed beam 210, so that the structure of the present embodiment can reliably limit the translation of the thin-shell structure 200.
