The connecting piece of the shock insulation device can transmit the shearing force of the shock insulation device under the action of rare earthquakes. Although the shock isolation device cannot transmit shearing force and bending moment, additional bending moment is generated by P-delta effect generated by horizontal shearing deformation of the shock isolation device and shearing force of the shock isolation device. The position, the number and the size of the connecting slide block and the overall dimension of the mounting groove in the buttress can be calculated according to the shearing force, the axial force and the additional bending moment.
As can be seen from appendix C of building seismic isolation design Standard (GB/T51408-2021), the formula for calculating the additional bending moment is as follows:
in the formula, V is the horizontal shearing force (N) borne by the support; h is the height (mm) of the shock isolation device; p is the vertical force (N) transmitted by the superstructure; delta is the horizontal shear deformation (mm) of the seismic isolation device.
The calculation of the size of the T-shaped mounting groove inside the buttress, the size of the buttress at the end part of the T-shaped mounting groove and the connecting slide block in the symmetrical slide block type shock isolation device mainly comprises the following steps:
(1) closed end size of T-shaped mounting groove
When the seismic action direction is parallel to the horizontal chute direction and points to the closed end of the T-shaped mounting groove, the shearing force is born by the closed end of the T-shaped mounting groove, and the local maximum stress of the concrete at the closed end is in accordance with:
in the formula, n is the number of the sliding blocks; s is the cross-sectional area (mm) of the connecting slider2) Equal to the cross-sectional area of the connecting slider; beta is acFor improving the coefficient of the concrete strength, when the concrete strength grade does not exceed C50, taking 1.0, when the concrete strength grade is C80, taking 0.8, and determining the concrete strength grade according to a linear interpolation method; beta is a1Increase the coefficient for the locally stressed strength of the concrete according to

(2) Connecting slider and connecting bolt of T-shaped mounting groove closed end
When the earthquake effect direction is on a parallel with the free end of the T-shaped mounting groove, the shearing force of the contact surface of the buttress and the shock isolation device is jointly born by the hexagon socket head cap bolts, and the pulling force born by the bolts is in accordance with:
in the formula, n is the number of the sliding blocks; m is the number of bolts on a single slide block;
is the cross-sectional area (mm) of the bolt2)；ftDesign strength for single bolt tensile (N/mm)2)。
(3) Connecting slide block
The axial pressure of a single connecting slide on the connecting plate of the seismic isolation device can be expressed as:
Ni＝P/n (4)
the additional bending moment M is determined by the formula (1), and under the action of the additional bending moment M, the sliders positioned on two sides of the neutral axis are respectively pulled and pressed on the assumption that the central position of the vibration isolation support is the position of the neutral axis. The pulling force applied to the slider at the upper end of the connecting plate can be expressed as:
in the formula, yiIs the distance between the sliders in the ith group.
Thus, the maximum tensile force experienced by a single link block can be expressed as:
Nt＝N1-Ni (6)
when N is presenttThe connecting slide block which bears shearing force and tensile force can meet the following requirements when the connecting slide block is more than 0:
in the formula, Nv、NtRespectively the shearing force (N) and the pulling force (N) born by the connecting slide block;

(4) Concrete strength of end part of T-shaped mounting groove in height direction
The strength of the concrete at the end part of the steel pipe is in accordance with:
in the formula, scIs the cross-sectional area (mm) of the end part of the T-shaped mounting groove in the height direction2) The area is shown in the shaded part of FIG. 3, and the other parameters have the same meaning(2)。
The number and the size of each connecting piece and each connecting slide block in the symmetrical slide block type shock isolation device are designed according to the method. The design flow is shown in fig. 7.
The concrete construction process of the invention is as follows:
first, the lower pier 9 is constructed. In the process of binding the lower buttress 9 steel bar cage, paying attention to the binding of steel bars at the position of the inverted T-shaped mounting groove, reserving a bolt connecting hole at the end face of the inverted T-shaped mounting groove, and after the steel bar cage is fixed, carefully checking the size of each detail by using a caliper; in the process of pouring the lower buttress concrete, the flatness of each interface is ensured; after the concrete reaches a certain strength, thinly coating a friction material on the inner surface of the inverted T-shaped mounting groove to finish the construction of the lower buttress 9;
the design of the upper buttress 5 is similar to that of the lower buttress 9, in order to ensure that a subsequent shock insulation device can be smoothly installed, a shock insulation device installation space is reserved, and at the moment, a rigid iron block with the same height as the shock insulation device is required to be placed right above the lower buttress 9 and serves as a support of a template of the upper buttress 5; then, binding a reinforcement cage of the upper buttress 5, paying attention to the binding of the reinforcement at the position of the T-shaped mounting groove, reserving a bolt connecting hole at the end face of the T-shaped mounting groove, and checking the space and the flatness of the reinforcement; pouring concrete of the upper buttress, and after the concrete reaches a preset strength, thinly coating a friction material on the inner surface of the T-shaped mounting groove to finish the construction of the upper buttress 5;
then, the installation of the symmetrical slider type seismic isolation device is started. Horizontally and slowly moving out the rigid blocks between the buttresses, and firstly installing an upper connecting slide block 4 and a lower connecting slide block 8 at preset positions of an upper connecting steel plate 2 and a lower connecting steel plate 3 by using a cementing material to ensure that the shock insulation device is installed smoothly;
the shock insulation device provided with the upper connecting slide block 4 and the lower connecting slide block 8 is slowly pushed in along the direction parallel to the reserved sliding groove in the buttress until the side surface of the slide block is contacted with the side surface of the mounting groove on the buttress, the shock insulation device can be smoothly mounted, and if the slide block cannot be mounted due to construction errors, the fixed position of the slide block on the connecting plate is finely adjusted to meet the requirements; then, slowly pulling out the shock insulation device along the direction parallel to the mounting groove, respectively connecting the upper connecting slide block 4 and the lower connecting slide block 8 with the upper connecting steel plate 2 and the lower connecting steel plate 3 into a whole in a welding mode, and horizontally pushing the shock insulation device along the direction parallel to the sliding groove until the end surfaces of the shock insulation device coincide;
and finally, fixing the vibration isolation device. Firstly, a lower connecting slide block 8 and a lower support pier 9 are connected into a whole by using an inner hexagon bolt 6, and meanwhile, an upper connecting slide block 4 and an upper support pier 5 are connected into a whole by using the inner hexagon bolt 6; then, a lower sleeve 10 is arranged outside the lower buttress 9, the left part and the right part of the lower sleeve 10 are arranged on the lower buttress 9 and connected by screws and steel plates, so that the periphery of the inner surface of the lower sleeve 10 is contacted with the side surface of the lower buttress 9, and the top of the inner surface of the lower sleeve 10 is contacted with the upper surface of the lower buttress 9;
for the upper buttress 5, the left part and the right part of the upper sleeve 7 are arranged outside the buttress, and are connected into a whole by using steel plates and bolts, and it is worth noting that in order to limit the sliding of the sleeve outside the upper buttress 5 under the action of gravity and influence the horizontal displacement performance of the shock insulation device, the area of the upper connecting steel plate 3 is larger than the cross-sectional area of the upper buttress, and at the moment, the installation of the shock insulation device is completed;
because the horizontal shear rigidity of the shock isolation device is far less than the rigidity of the connecting piece, the general shock isolation device is damaged firstly, if the shock isolation device needs to be replaced after the shock is absorbed, the shock isolation device can be horizontally pushed out along the direction parallel to the mounting groove only by loosening the connecting bolt on the sleeve, detaching the sleeve and then loosening the connecting bolt on the buttress, so that the damaged shock isolation device is detached and replaced.
