Problems solved by technology

Although the scheme described in this patent application can improve the tensile strength of the three-dimensional seismic isolation device to resist the huge tension generated by the swaying or even overturning of high-rise buildings in an earthquake, the following deficiencies still exist: 1. The spring isolation The support can only be compressed for energy consumption and shock absorption, but cannot be stretched for energy consumption and shock absorption; 2. The spring isolation support cannot preset the early stiffness, which is not convenient for presetting the seismic intensity to reduce the cost of isolation
However, this invention still has the following disadvantages: 1. The load connecting rod is balanced under the joint action of two groups of disc springs. Although the preload of the two groups of disc springs can be adjusted, no matter how they are adjusted, the The force of the disc spring on the load connecting rod is a set of equal and opposite forces. Just applying any external force on the load connecting rod will destroy this balance and deform the two sets of disc springs. Therefore, the 2. In this invention, two sets of disk springs must be used together to provide damping when the damper is under compression or tension load, which not only causes a certain waste, but also makes the damper greatly increased in length
It can be seen that although the stiffness of the spring in the patent application scheme can be changed, the effective working length of the spring is not only significantly shortened, but also can only be compressed for energy consumption and vibration reduction, and cannot be stretched for energy consumption and vibration reduction.

example 1

[0032] see figure 1 , the three-dimensional isolation device in this example consists of laminated rubber isolation bearings and vertical isolation bearings connected in series up and down.

[0033] see figure 1 and Figure 4, the laminated rubber shock-isolation bearing includes an upper connecting plate 14, a lower connecting plate 15, a laminated rubber pad 17 clamped between the upper and lower connecting plates and six tensile steel cables 16; wherein, the upper Both the connecting plate 14 and the lower connecting plate 15 are disc-shaped, and the edge of the upper connecting plate 14 is provided with mounting holes 13; the main body of the laminated rubber pad 17 is alternately composed of a layer of rubber 17-1 and a layer of steel plate 17-2 After lamination, it is molded and vulcanized, and a rubber protective layer 17-3 is naturally formed around it during the process of molded vulcanization. The upper and lower end surfaces of the main body of the laminated ru...

example 2

[0043] This example has the following differences from Example 1:

[0044] see Figure 7-9 , the first group of preloaded steel cables 8 and the second group of preloaded steel cables 7 are composed of three preloaded steel cables. The number of said rigging turnbuckles 18 is reduced to six, and they are connected in series in the middle of each preloaded steel cable respectively.

[0045] see Figure 7-9 In order to prevent dust and other sundries from falling on the disc spring group 4 and affect the normal operation of the damper, a protective cover 19 of rubber is wrapped on the outside of the back pressure device, and the two ends of the protective cover 19 are connected with the first floating pressure plate respectively. 6 and the outer peripheral surface of the second floating platen 5 are bonded together. The length of the sheath 19 is greater than the distance between the upper surface of the upper end plate 2 and the lower surface of the lower end plate 3, so as ...

example 3

[0048] see Figure 10-12 , the difference between this example and Example 2 is: the upper end plate 2 is disc-shaped, and the middle part of the lower end plate 3 bulges upwards in an inverted washbasin shape; the upper end of the guide rod 1 is connected to the upper end plate The middle part of the lower surface of 2 is fixedly connected into one body, and the lower end extends downward along the central hole of the disc spring group 4 to pass through the upwardly raised middle part of the lower end plate 3; the lower end plate 3 is dynamically matched with the outer surface of the guide rod 1 . Between the lower surface of the raised middle part of the lower end plate 3 and the lower surface of the edge of the lower end plate 3 is formed a flexible space 11 for the lower end of the guide rod 1 to expand and contract. The first group of preloaded steel cables 8 and the second group of preloaded steel cables 7 are composed of five preloaded steel cables; The middle part of...

Abstract

The invention discloses a three-dimensional shock isolation device capable of adjusting vertical early rigidity. The three-dimensional shock isolation device comprises a layered rubber shock isolation support base and a vertical shock isolation support base which are in sequential up-down series connection. The three-dimensional shock isolation device is characterized in that a reverse pressing device is arranged between two end plates of the vertical shock isolation support base, and comprises two pre-pressing steel cables and two floating press plates; the floating press plates sleeve a guide rod between one end plate and a disc spring set; the pre-pressing steel cables are symmetrically distributed around the disc spring set in a linear state by winding the axis of the guide rod; one end of each pre-pressing steel cable is fixed to one floating press plate, and the other end of each pre-pressing steel cable penetrates the other floating press plate to be fixed to the end plate adjacent to the floating press plate; each pre-pressing steel cable is strung with a rigging turnbuckle; the pre-pressing steel cables are tensioned to enable the disc spring set to be constantly clamped between the two floating press plates.

Description

technical field [0001] The invention relates to a building anti-vibration (or shock) device, in particular to a three-dimensional shock-isolation device in which a sandwich steel plate rubber pad is connected in series with a vertical shock-isolation support. Background technique [0002] The seismic isolation device is an anti-seismic isolation device installed between the building and the foundation. The early seismic isolation devices were mainly two-dimensional isolation bearings (laminated rubber isolation bearings) composed of rubber and thin steel plates alternately laminated, which could only isolate the horizontal component of seismic waves. With the improvement of people's understanding of the multi-dimensional characteristics of earthquakes, three-dimensional seismic isolation devices have gradually attracted the attention of researchers in this field. The most common three-dimensional isolation device is composed of laminated rubber isolation bearings connected ...
