Description
Technical Field
The invention relates to the technical field of building shock insulation supports, in particular to a fusing component, a fusing type building shock insulation rubber support and a building.
Background
The traditional earthquake-proof technology is to firmly connect the superstructure of a building with a foundation, and in order to cover a house more firmly, thicker steel bars and more concrete are used for pouring, but the earthquake-proof effect is not ideal. The isolation bearing is formed by adding an isolation layer between an upper structure and a foundation and installing a rubber isolation bearing to play a role in soft connection with the ground, and through the technology, about 80% of energy of an earthquake can be offset. The rubber isolation bearing is a fusing type building isolation rubber bearing in isolation bearings, and is formed by alternately laminating multiple layers of steel plates and rubber, and the steel plates are used as stiffening materials of the rubber bearing, so that the characteristic of small vertical rigidity of a rubber body is changed, the rubber isolation bearing can reduce the horizontal earthquake effect and bear large vertical load.
At present, the earthquake intensity exceeding the probability of 10 percent within 50 years is specified in GB 50011-plus-2010 building earthquake design Specification as earthquake fortification intensity. Meanwhile, the shear strain related to horizontal shear displacement of the rubber shock-insulation support of the specified shock-insulation layer can be 100% under the action of fortification earthquake, 250% under the action of rare earthquake and 400% under the action of extremely rare earthquake. The support is therefore subjected to only horizontal deformation below 100% shear strain displacement in normal use conditions.
When the support form adopted in the field at present receives the horizontal shearing action under the condition of not reaching the seismic fortification intensity in the daily use process, the support offsets the horizontal force through the deformation of less than 100 percent shearing strain displacement. The rubber property determines that the rubber is subjected to frequent stretching, and the resistance of the rubber to horizontal deformation is gradually reduced. Therefore, in daily use and earthquake-prone areas, after the support is subjected to high-frequency and low-intensity horizontal shearing action at ordinary times, the horizontal resistance of the support is gradually attenuated, and the situation that the horizontal deformation resistance of the support is insufficient under the action of rare earthquakes is easily caused.
Meanwhile, under the condition that the upper building is subjected to long-term unbalance loading, the support can have the condition that the shear deformation in a single direction cannot be recovered for a long time, and in the state, the support can be adversely affected.
The service performance which is most important to the requirement of the building isolation bearing in the current market is the deformation capacity under the extreme displacement, namely the main action range of the building isolation bearing is the large deformation capacity after the shear strain of more than 100%, and the deformation equal to or less than 100% is mainly used as the conventional performance detection and the large deformation early-stage transition deformation of the bearing, so that the displacement of the bearing under the earthquake and daily use action of the earthquake lower than the fortification intensity is reduced as much as possible.

In another embodiment of the present invention, as shown in fig. 4, a conventional detection of deformation (100% shear strain) under the action of a ruggedized earthquake is organized separately for a conventional LRB-D600 building seismically isolated support. After the detection is finished, the fusing device is additionally arranged on the support, and the support with the fusing device is subjected to two experiments of slow horizontal shearing deformation and horizontal shearing deformation with 100% shearing strain respectively. The horizontal displacement curves are distinguished by observing and comparing the following three test modes:
a horizontal deformation test curve (figure 4, curve 1) of a support without the fusing device under the action of a simulated fortification earthquake;
horizontal deformation test curve of the support with the fusing device under slow shear deformation (fig. 4, curve 2);

Furthermore, the support with the fusing device is subjected to unidirectional shearing during slow shearing deformation, and the other two items are subjected to bidirectional shearing.
Furthermore, since the second module 5 and the third module 10 are divided into 4 identical components for cooperation, a section from node B to node C of the curve 2 represents a phenomenon from the beginning to the complete fusing of the 4 identical components. Since curve 3 is tested at a faster rate and 4 identical parts of the third assembly 10 are fused at the same time, curve 3 has no obvious break point.
The following is concluded from the above graphs and data:
by comparison of nodes B and E, and nodes B and F. Under the condition of slow deformation, the fusing device increases the performance of the support resisting the horizontal force under the same deformation condition and slows down the horizontal displacement deformation generated by the support under the same horizontal force value condition.
Through the curve changes of the nodes D and E and the two nodes, when the horizontal force under the effect of a fortification earthquake is achieved, the capability of the support for resisting vertical (horizontal) deformation is improved at the initial stage of the fusing device, and after the fusing device is fused, the curve trend is smooth and basically consistent with the curve trend of a non-fusing device. Therefore, the fusing device has no adverse effect on the support under the earthquake-proof effect.
In conclusion, the fusing device plays a role in protecting the building shock insulation rubber support body 7 in daily use and under the condition of earthquake lower than the fortification intensity, and does not have adverse effect on the performance of the building shock insulation rubber support body 7 under the action of fortification earthquake, so that the expected preset purpose is achieved.

The test chart also shows that in the specific implementation process, the correlation selection coefficient calculated by the test data correction theory can be used as a discussion direction for further research.
