Description
Technical Field
The invention belongs to the technical field of damping and shock insulation of engineering structures, and particularly relates to a foundation shock insulation composite limiting device.
Background
The earthquake-proof device such as a laminated rubber support and a friction sliding support is arranged on the earthquake-proof layer of the foundation earthquake-proof building, so that the side rigidity of the earthquake-proof layer is reduced, the horizontal displacement is increased, and the earthquake response of the upper structure is reduced. The earthquake-proof building is gradually widely applied due to excellent earthquake-proof performance, and at present, more than ten thousand earthquake-proof buildings exist in China. The earthquake-proof building may suffer from the earthquake action higher than the basic fortification intensity of the local area in the service period, or the earthquake-proof building may suffer from the earthquake action of long period, so that the horizontal displacement of the earthquake-proof layer is too large to cause the failure of the earthquake-proof support, and the whole earthquake-proof building is damaged.
In order to avoid failure caused by excessive horizontal displacement of the shock insulation support, a limiting measure is generally adopted in engineering to protect the shock insulation support. At present, limit devices commonly used for the shock insulation layer are roughly divided into two types, one type is that limit stops are directly arranged, such as limit baffles, U-shaped steel plates and the like, and the limit devices have high contact rigidity during collision, so that severe impact is brought to the shock insulation layer, and the shock insulation layer is easy to damage; the other is that by arranging elastic devices such as springs and rubber, the devices can only store energy, but cannot consume energy, when the shock insulation layer returns to the balance position after reaching the maximum horizontal displacement, the elastic potential energy stored on the limiting device is totally acted on the structure, so that the limiting efficiency is lower.
Disclosure of Invention

The beneficial effects of the invention are as follows: the existing horizontal limiting device for the base shock insulation structure shock insulation layer has the problems of overlarge limiting rigidity, lower limiting effect and the like, or the structure is locally damaged secondarily in the limiting process. Compared with the prior device, the invention has the following advantages: (1) The buffer is made of soft steel materials with good deformability and rubber materials with super-elasticity, so that the buffer can realize larger deformation, has enough lateral rigidity resistance to prevent the shock insulation layer from excessively deforming horizontally, has certain energy consumption capacity, and further enhances the shock resistance of the shock insulation layer; (2) According to the invention, the two materials are combined together to form the composite limiting device, the soft steel mainly plays an energy consumption role, and the super-elastic body provides enough restoring force for the soft steel, so that the advantages of the two materials are fully exerted; (3) The horizontal rigidity of the invention is gradually increased along with the increase of deformation, and the invention can not generate excessive impact on the shock insulation layer and generate secondary damage to the structure; (4) The invention has simple structure, good economy, convenient installation and repeated use.

The invention is described in further detail below with reference to the attached drawings and detailed description:
example 1: as shown in fig. 1 to 8, the invention relates to a basic shock insulation composite limiting device, and the structural system mainly comprises a collision plate 1, a first buffer 2, a second buffer 3, a connecting plate 4, a constraint plate 5, a first connecting bolt 6, a horizontal lateral force resisting member 7 and a second connecting bolt 8; the first buffer 2 includes two specifications, denoted as first buffer one 2-1 and first buffer two 2-2. When the components are processed and manufactured, the collision plate 1 and the connecting plate 4 are obtained by cutting and perforating common steel plates; the first buffer 2 is made of mild steel, firstly, steel plates are cut into steel belts with different widths, then the steel belts are bent and formed, bolt holes are formed in straight sections at two ends, internal threads are formed in the bolt holes, and the thread specification is required to be matched with that of the first connecting bolt 6; the second damper 3 is formed by compressing a rubber material in a mold at a high temperature; the restraint plate 5 and the horizontal lateral force resisting member 7 are obtained by cutting, splicing and welding common steel plates; the first connecting bolt 6 is a high-strength inner angle bolt, and the second connecting bolt 8 is a common high-strength bolt or an expansion type foundation bolt. When the composite limiting device is assembled, firstly, three first buffers 2 (a first buffer I2-1 and two first buffers II 2-2) are arranged in parallel, the first buffer I2-1 is arranged in the middle, the first buffers II 2-2 are arranged on two sides, a certain gap is reserved between the first buffers I2-1 and the first buffers II 2-2, and the arrangement directions of the first buffers II and the first buffers II 2-2 are opposite; then, the four second buffers 3 are sequentially inserted into a space surrounded by two adjacent straight sections and an arc section of the first buffer 2, at the moment, the upper end and the lower end of each second buffer 3 are just restrained by the bending section of the first buffer 2, and the front end and the rear end of each second buffer are restrained by the straight sections of the first buffer 2; then, the crash plate 1 and the first buffer 2 are fixedly connected through the first connecting bolts 6, and the restraint plates 5 are required to be welded and fixed on two sides of the crash plate 1 in advance; finally, fixing the assembled whole and the connecting plate 4 by adopting a first connecting bolt 6, and enabling the free end of the constraint plate 5 to just pass through a T-shaped hole reserved on the connecting plate 4; the connecting plate 4 and the horizontal lateral force resisting member 7 are fixed by welding; finally, the horizontal lateral force resisting member 7 is connected with the foundation 9 through a second connecting bolt 8. When the limiting device is installed, a certain distance is reserved between the collision plate 1 and the support pier 10 on the shock insulation layer, when the shock insulation layer is subjected to larger horizontal displacement, the support pier 10 on the shock insulation layer is in contact with the collision plate 1, and the first buffer 2 and the second buffer 3 are extruded, so that the first buffer 2 is subjected to elastoplastic bending deformation, the second buffer 3 is subjected to elastic deformation, and the two buffers provide lateral rigidity resistance together, so that the limiting function is exerted. When the vibration isolation layer moves to the balance position after reaching the maximum horizontal displacement, the second buffer 3 rapidly releases the stored elastic energy to start the recovery deformation, and the first buffer 2 is forced to generate the recovery deformation; when the shock insulation layer collides with the limiting device again, the limiting device repeats the deformation and plays a limiting function again.
Example 2: as shown in fig. 1 to 7 and 9, the processing, manufacturing and assembling processes of each part in the limiting device are exactly the same as those of embodiment 1, and the difference is mainly represented in the connection mode of the limiting device and the foundation. If a ready-made reaction support 14 is present around the seismic isolation layer, such as a wall, a reaction wall, etc., the spacing device may be mounted directly to the reaction support 14. Specifically, the connecting plate 4 of the limiting device is fixedly connected with the counterforce support 14 through a connecting plate connecting piece 13 and a second connecting bolt 8. The web engagement members 13 may be cut, spliced, welded from conventional sheet steel into a unitary component that must have sufficient resistance to lateral stiffness. The connecting plate connecting piece 13 is fixed with the connecting plate 4 through welding; a certain distance must be reserved between the connecting plate 4 and the counter-force support 14, and when the limiting device is compressed, it must be ensured that the free end of the restraining plate 5 does not collide with the counter-force support 14.

If the vibration isolation layer does not have the foundation 9 platform convenient for installing the limiting device, the limiting device can be directly fixed on the lower support pier 12 of the vibration isolation layer, and only one side force resisting component connecting piece 15 is needed to be designed and processed at the moment. The lateral force resisting member connecting piece 15 is formed by cutting, splicing and welding common steel plates, one end of the lateral force resisting member connecting piece is fixed with the horizontal lateral force resisting member 7 through a second connecting bolt 8, and the other end of the lateral force resisting member connecting piece is fixed with the seismic isolation layer lower buttress 12 through the second connecting bolt 8.
