Problems solved by technology

However, the disadvantages of these devices cannot be ignored
The original seismic isolation building technology has poor seismic isolation effect, and the isolation structure is single, and the ability to resist torsion / swaying / overturning is very poor. It can only rely on gravity to resist earthquake overturning force, which limits the application of seismic isolation structures in high-rise buildings. , can not achieve the expected effect

Embodiment 1

[0028] Such as figure 1 As shown, the present invention provides a separate anti-sway three-dimensional seismic isolation structure comprising: superstructure 1, horizontal seismic isolation device 2, basement 3, vertical limit slide 4, vertical seismic isolation device 5, foundation pit 6, wherein A number of vertical seismic isolation devices 5 are fixed above the foundation pit 6 to isolate the vertical seismic action on the basement 3 and the superstructure 1; Smooth installation, there is a certain gap between basement 3 and foundation pit 6 retaining walls.

[0029] In this embodiment, the length of the overhanging part of the beam in the basement 3 is used to fix the vertical limit slide 4; one end of the vertical limit slide 4 is fixed to the overhang of the beam, and the other end is fixed to the retaining wall of the foundation pit 6 , the vertical sliding plate 4 makes the overall structure only slide vertically during an earthquake, and can control the overall tor...

Embodiment 2

[0035] Such as Figure 4 As shown, the difference between this embodiment and embodiment 1 is:

[0036] The number of vertical limit slides 4 used in this example is increased to forty-eight. The layout is such that the beams around the basement 3 extend a certain length to the gap between the retaining walls of the foundation pit 6, and vertical limit slides are installed on the overhanging parts of the beams. bit skateboard4. Sixteen verticals are arranged on the first floor of this scheme, and there are three layers of beams stretching out, so the number of vertical limit slides 4 arranged is totally forty-eight.

Embodiment 3

[0038] Such as Figure 5 as shown, Figure 5 It is a front view and a side view of the construction process of a certain side of the basement 3. This embodiment provides the construction sequence of the vertical limit slide plate, wherein Figures a1 and a2 are the side view and front view of the vertical limit slide plate 4 before installation, and the frame of the basement 3 Preliminary pouring has been completed and a gap with the retaining wall of the pit 6 has been reserved, and the beam that needs to be installed in the design to install the vertical limit slide 4 has been stretched out, and the basement wall 9 has not yet been poured. Figures b1 and b2 are side views and front views when the vertical limit slide 4 is installed. The limit slide plate 8 is fixed on the overhanging part of the beam, and the limit fixed plate 7 is fixed at the corresponding position of the retaining wall of the foundation pit 6. After the installation of the vertical limit slide 4 is comple...

Abstract

The invention belongs to the field of building seismic isolation structures, and particularly discloses a separating type anti-swing three-dimensional seismic isolation structure. The separating type anti-swing three-dimensional seismic isolation structure comprises an upper structure, a horizontal seismic isolation device, a basement, a vertical limiting sliding plate, a vertical seismic isolation device and a foundation pit, wherein the vertical seismic isolation device is fixed on the foundation pit and used for bearing the basement, the vertical seismic isolation device is a lead core rubber support or a thick-layer rubber support, the horizontal seismic isolation device is installed at the top of the basement, the upper portion of the horizontal seismic isolation device bears the upper structure, a gap is formed between the periphery of the basement and the foundation pit, and the vertical limiting sliding plate for connecting a foundation pit retaining wall and the basement is installed in the gap. According to the three-dimensional seismic isolation structure, through the horizontal seismic isolation device and the vertical seismic isolation device which are arranged separately, the upper structure has the three-dimensional six-direction seismic isolation effect, so that the use function of a building structure is guaranteed, and the structural safety is improved.

Description

technical field [0001] The invention relates to the field of building shock-isolation structures, in particular to a separated anti-sway three-dimensional shock-isolation structure. Background technique [0002] Earthquake is a natural disaster that plagues human beings. In order to reduce the loss of life and property caused by earthquakes, human beings have carried out long-term and unremitting struggles against it. With the advancement of science and engineering technology, the theory and practice of earthquake engineering have developed rapidly. As an effective control technology, seismic isolation technology has been widely used in various engineering structures, and has become one of the most important means to reduce earthquake hazards. For example, base isolation can extend the natural vibration period of the entire structural system and reduce the seismic response of the structure by adding an isolation layer between the foundation and the superstructure. In turn,...
