Description

Technical Field

[0001] The invention belongs to the technical field of seismic isolation building engineering, and specifically relates to a lifting type elevator structure of a seismic isolation building, which is applied to a seismic isolation building in which the height of the elevator shaft above the seismic isolation layer is smaller than the height of the elevator shaft below the seismic isolation layer. Background Art

[0002] At present, the conventional through-type elevator (elevator passing through the seismic isolation layer) mainly adopts the hanging type or hanging support type (such as attached Figure 1 , 2 As shown, Figure 1 It is a suspended elevator structure that passes through the seismic isolation layer. Figure 2 For the hanging support type elevator structure that passes through the seismic isolation layer). For some elevator shafts that are hung deep, the use of the hanging type requires higher stiffness of the elevator shaft and the hanging beam on it, which will increase the thickness of the elevator shaft and reduce the usable space. If the hanging support type is used, when the height difference between the foundation pit support and the seismic isolation layer is large, the seismic isolation bearing may not work synchronously; in addition, the main material in the hanging shaft is obviously tensile, and it cannot fully utilize the characteristics of concrete that it is compressed but not tensile, affecting the safety and rationality of the construction project. Summary of the invention

[0003] In view of this, the present invention provides a lifting elevator structure for a seismic isolation building, providing an optimized structural solution for a seismic isolation building in which the height of the elevator shaft above the seismic isolation layer is smaller than the height of the elevator shaft below the seismic isolation layer.

[0004] The lifting elevator structure of the seismic isolation building includes: a lifting frame, a filling partition wall A and an elevator shaft;

[0005] The lifting frame is a rectangular frame structure with an open bottom surface, which is vertically arranged on the bottom plate of the seismic isolation layer, and the opening area at the bottom of the lifting frame faces the lower part of the elevator shaft, and the lifting frame is embedded with a filling partition wall C;

[0006] A filling partition wall B is provided at the connection between each floor of the building and the elevator shaft below the bottom plate of the seismic isolation layer;

[0007] The height of the lifting frame exceeds the height of the seismic isolation layer;

[0008] The supporting frame is surrounded by a filling partition wall A, the bottom of which is supported on the top plate of the seismic isolation layer;

[0009] The bottom end surface of the lifting frame is vertically aligned with the top end surface of the filling partition wall B, together forming a complete vertical elevator shaft.

[0010] Preferably, an elevator top plate is provided on the top of the filling partition wall A, supported on the lifting frame;

[0011] Seismic isolation trenches are provided around the supporting frame and between the filling partition wall A.

[0012] Preferably, a moving connection piece is provided between the lifting frame and the top plate of the seismic isolation layer;

[0013] The kinematic connection element can move freely in a horizontal plane.

[0014] Preferably, the lifting frame is made of a steel frame structure.

[0015] Preferably, the lifting frame adopts a reinforced concrete cylinder structure.

[0016] Beneficial effects:

[0017] 1. The use of a lifting frame in the present invention can get rid of the requirements of the traditional elevator shaft on the rigidity of the hanging beam, reduce the number of double-layer partition walls, optimize the cantilever thick tube into a frame plus a filling partition wall, reduce the mass and main structure load, save costs and reduce the space occupied by the elevator.

[0018] 2. The lifting frame in the present invention makes full use of the characteristic that the compressive performance of concrete is higher than its tensile performance, and optimizes the long cantilever hanging structure into a low lifting structure. The structure is more reasonable and it is easier to meet the deformation and stiffness requirements required for equipment operation, thereby improving the stability of the lifting elevator structure.

[0019] 3. The moving connection member in the present invention can move freely in the horizontal plane to prevent people from falling from the gap between the elevator shaft and the lifting frame. BRIEF DESCRIPTION OF THE DRAWINGS

The lifting frame 1 is a rectangular frame structure with an opening at the bottom, and the lifting frame 1 has a filling partition wall C embedded therein (the lifting frame 1 is a rectangular frame structure, and the rectangular frame on each side thereof has a filling partition wall C inside); the lifting frame 1 is vertically arranged on the bottom plate 7 of the seismic isolation layer, and the bottom opening area of ​​the lifting frame 1 faces the bottom of the elevator shaft opening, and a filling partition wall B8 is arranged around the connection between the floor below the bottom plate 7 of the seismic isolation layer and the elevator shaft 3, and the top end face of the filling partition wall B8 is vertically aligned with the bottom end face of the lifting frame 1, together forming a complete vertical elevator shaft 3.

[0027] The height of the lifting frame 1 exceeds the height of the seismic isolation layer, that is, the lifting frame 1 passes through the top plate 6 of the seismic isolation layer, and is used to provide a moving space for the elevator box moving in the elevator shaft 3.

[0028] A filling partition wall A2 is arranged around the lifting frame 1, and the bottom of the filling partition wall A2 is supported on the top plate 6 of the seismic isolation layer. A seismic isolation groove is arranged between the lifting frame 1 and the filling partition wall A2;

The movable connecting member 5 can move freely in a horizontal plane to prevent people from falling from the gap between the elevator shaft 3 and the lifting frame 1 .

[0031] A filling partition wall B8 is provided at the connection between each floor and the elevator shaft 3 below the seismic isolation layer bottom plate 7. The filling partition wall B8 of each floor is vertically aligned to form a complete vertical elevator shaft 3 with the lifting frame 1.
