Description
Technical Field
The utility model relates to the field of buildings, in particular to a vibration and shock double-isolation combined shock isolation system.
Background
With the rapid development of rail transit including high-speed rail and subways and the continuous encryption of urban rail transit networks, more and more construction projects cannot avoid adjacent or crossing rail transit. According to the statistical data of subway vibration of Beijing, Shanghai and Guangzhou, the ground vibration induced by the subway is mainly vertical vibration. For buildings adjacent to rail transit, when vertical vibration exceeds the national regulation limit, necessary vibration reduction measures are required, particularly for buildings with high vibration requirements such as theaters, music halls, museums, sophisticated laboratories and the like, and environmental vibration and noise control become problems which must be solved in the design of building structures.
Earthquake is a natural phenomenon which cannot be avoided by human beings. Under the action of earthquake, the building can be greatly horizontally deformed and even collapsed. The shock insulation technology achieves the shock absorption purpose by prolonging the self-vibration period of the structure, and after the shock insulation technology is adopted, the shock resistance of the building is obviously improved, so that the shock insulation system is suitable for various buildings such as disaster prevention and relief buildings, school buildings, important infrastructure buildings, houses, offices and the like in high-intensity earthquake areas. The seismic isolation technology is one of the most effective means for relieving earthquake disasters, and the building does not collapse in the earthquake.
The spring vibration isolator is an important means for controlling vertical vibration, however, because the allowable horizontal limit deformation of the spring vibration isolator is very small, generally only 20-50 mm, when the allowable horizontal limit deformation is exceeded, the vertical bearing performance of the spring is sharply reduced, and the control of the horizontal deformation of the spring vibration isolator not exceeding the limit value is a crucial factor for engineering safety. In non-seismic areas, the horizontal deformation of the building is small, and the vertical vibration of the structure can be reduced by adopting the spring vibration isolator. In the earthquake region, the earthquake action can cause larger horizontal deformation of the building, and when the spring vibration isolator is adopted to reduce the vertical vibration of the structure, other measures are needed to be set, so that the horizontal deformation of the spring vibration isolator is controlled within an allowable range.
At present, when a spring vibration isolator is adopted in a seismic region to control vertical vibration, a viscous damper is adopted to control the horizontal deformation of the spring vibration isolator, namely, the damper is arranged on a vibration isolation layer, the deformation of the vibration isolation layer is reduced through the energy consumption of the damper, the horizontal deformation of the spring vibration isolator is controlled within a limit value range, and meanwhile, the vertical vibration damping effect of the spring vibration isolator is not influenced. Because the allowed horizontal displacement of the spring vibration isolator is small, a viscous damper with a large tonnage is needed to limit the displacement of the vibration isolation layer within the displacement limit value of the spring vibration isolator. The large-tonnage damper not only has high manufacturing cost, but also has large internal force of the components at the joint and complex connection structure. Because the displacement of the vibration isolation layer is limited within a very small range by the damper, the horizontal equivalent stiffness of the vibration isolation layer is large, the seismic action transmitted to an upper building cannot be effectively reduced, the vibration isolation effect is poor, and the double isolation target of vertical vibration and horizontal earthquake is difficult to realize.

Detailed Description
The following describes an embodiment of the present invention with reference to the drawings. Fig. 1A is a schematic diagram of the basic structure of a horizontally slidable vertical vibration damping mount 300 according to an embodiment of the present invention, and fig. 1B is an AA sectional view of fig. 1A. As shown in fig. 1A, a horizontally slidable vertical vibration damping mount 300 is installed between an upper structure 100 (belonging to an upper building) and a lower structure 200 (belonging to a foundation or a lower building). The vertical vibration damping support 300, which is horizontally slidable, may be divided into an upper part and a lower part, which are slidable therebetween, and have a horizontal vibration damping function.
Referring to fig. 1A, the upper portion includes, from top to bottom: a support upper connection plate 1001, an upper stiffener 1004, a spring upper connection plate 1011, a plurality of side-by-side springs (steel springs 1009 are shown in the figure, and the steel springs 1009 may be arranged in an array, as shown in fig. 1B), a spring lower connection plate 1012, a lower stiffener 1008, a support base plate 1013, a slip material 1015; wherein the upper connecting plate 1001 of the support is connected with the upper building through a socket hexagon head bolt 1010. The lower part comprises a mirror stainless steel plate 1016 and a pedestal lower connecting plate 1002, wherein the pedestal lower connecting plate 1002 is connected with a lower foundation or lower building through a socket hexagon head bolt 1010.
In the case of horizontal large deformation, the springs may be deformed and thus may fail, so in the present embodiment, an inner sleeve 1005 and an outer sleeve 1006 are disposed at outer rings of the plurality of springs and are respectively connected to the upper spring connecting plate 1011 and the lower spring connecting plate 1012 through bolts 1007 or vice versa. The outer sleeve 1006 is sleeved on the inner sleeve 1005, the inner sleeve 1005 is sleeved on the spring, a first gap is left between the outer sleeve 1006 and the inner sleeve 1005, the first gap is smaller than the horizontal deformation requirement of the spring, and the damping rubber ring 1023 or other damping materials are arranged in the first gap. When the structure generates horizontal deformation in earthquake, the inner sleeve and the outer sleeve are mutually propped against each other, so that the large horizontal deformation of the spring is avoided; when the damping rubber ring 1023 (or other damping material) is arranged in the first gap, the outer sleeve 1006 is pressed against the inner sleeve 1005 by the damping rubber ring 1023 (or other damping material), so that the horizontal force of the spring support is effectively transmitted, and the horizontal deformation of the spring is effectively restrained. In order to improve the rigidity and the strength of mutual abutting of the inner sleeve and the outer sleeve, the wall thickness of the inner sleeve and the wall thickness of the outer sleeve can be thickened, and the diameter of the bolt 1007 is increased.
For a spring array formed by a plurality of parallel springs, the inner sleeve and the outer sleeve can be arranged on only the outer ring spring of the array, or the inner sleeve and the outer sleeve can be arranged on all the springs.
The inner sleeve and the outer sleeve jointly restrain the horizontal deformation of the spring, and meanwhile, the vertical stress of the spring is not influenced; when the horizontally slidable vertical shock mount 300 takes up a horizontal force, as shown for example, when the horizontal deformation of the upper spring attachment plate 1011 exceeds the first gap width between the inner and outer sleeves, the horizontal force is transmitted from the upper attachment plate to the inner sleeve 1005, and the inner sleeve 1005 transmits the horizontal force to the outer sleeve 1006 and from the outer sleeve 1006 to the lower spring attachment plate 1012. When the upper building bears horizontal force, the horizontal force of the upper spring connecting plate 1011 is firstly transmitted to the inner sleeve 1005, the inner sleeve 1005 transmits the horizontal force to the outer sleeve 1006 through the damping rubber ring 1023 (or other damping materials), and the outer sleeve 1006 transmits the horizontal force to the lower spring connecting plate 1012, so that the effective transmission of the horizontal force of the spring support is realized.
The following description of the rubber mount 400 according to the embodiment of the present invention refers to fig. 2A and 2B, and fig. 2A is one of the schematic views of the basic structure of the rubber mount 400 according to the embodiment of the present invention. As shown in fig. 2A, the rubber mount 400 is installed between the upper structure 100 (belonging to the upper building) and the lower structure 200 (belonging to the foundation or the lower building), and includes, from top to bottom, an upper buried plate 1003 of the rubber mount, an upper mount plate boot cap, a rubber laminate 1019, a lower connecting plate of the rubber mount, and a lower buried steel plate. And a socket hexagon head bolt 1010 penetrates through the rubber support upper buried plate 1003 and is connected to an upper building. And a socket hexagon head bolt 1010 penetrates through the lower connecting plate and the lower embedded plate of the rubber support and is connected to the lower structure 200.
The rubber support 400 further comprises a damping rubber ring 1023, a limiting baffle plate and a damping rubber pad 1020, the shape of the upper support plate boot cap is similar to that of an oblate box, and the upper support plate boot cap comprises an upper support plate 1024, an inner side stiffening plate 1026, an upper support plate boot cap ring plate 1021 and a top plate 1025 from bottom to top; corresponding to the lower bottom surface, the side surface and the upper bottom surface of the oblate box, respectively. Namely, an upper support plate 1024, an upper support plate boot ring plate 1021 and a top plate 1025 are sequentially connected according to the position relation of the lower bottom surface, the cylindrical surface and the upper bottom surface of the cylinder; and the outer limit ring plate 1022 is in a position relation of an inner ring and an outer ring. Namely an upper support plate boot ring plate 1021, a damping rubber ring 1023 and an outer side limit ring plate 1022 are arranged in sequence from inside to outside, and it can be seen that there is no fixed connection between the support plate boot ring plate 1021 and the outer side limit ring plate 1022, that is, the two can be vertically separated.
The limiting baffle plate comprises an outer limiting ring plate 1022 and an outer stiffening plate; the outer limit ring plate 1022 is connected with the rubber support upper buried plate 1003, and is arranged on the outer ring of the upper support plate boot ring plate 1021, and a damping rubber ring 1023 is arranged between the two; the outer stiffening plate is connected to the outer side of the outer limit ring plate 1022 and is vertically connected to the rubber support upper buried plate 1003; a damping rubber pad 1020 is arranged above the top plate 1025, and a second gap S is reserved between the damping rubber pad 1020 and the rubber support upper buried plate 1003. The lower part of the upper support plate 1024 is connected with the top of the rubber laminate 1019, and the upper part is vertically connected with the inner side stiffening plate 1026.
Fig. 2B is a second schematic view of the basic structure of the rubber mount 400 according to the embodiment of the present invention. As shown in fig. 2B, a plurality of anti-pull bolts 1018 are provided on the upper seat plate boot, and the anti-pull bolts 1018 are connected to the upper structure 100 through the upper seat plate boot, the cushion rubber 1020, and the rubber seat upper countertop 1003. That is, the anti-pull bolts 1018 are distributed along the circumference of the inside of the upper bracket plate boot ring plate 1021, and adjacent anti-pull bolts 1018 are separated by an inside stiffener plate 1026. A first through hole is formed in the boot cap of the upper support plate, a second through hole is formed in the damping rubber pad 1020, and the first through hole is communicated with the second through hole; the anti-pull bolt 1018 penetrates through the first through hole and the second through hole, and the circumferential diameter of the anti-pull bolt 1018 is smaller than the circumferential diameter of the first through hole and the second through hole, that is, a gap is provided between the anti-pull bolt 1018 and the upper seat plate boot cap and the vibration damping rubber pad 1020, so that the anti-pull bolt 1018 is prevented from bearing horizontal force. When the upper structure 100 is subjected to a large horizontal load (wind load, earthquake action, or the like), an overturning moment is generated, and the pulling force borne by the rubber mount 400 can be reduced by the anti-pulling bolt 1018, so that the risk of the upper structure 100 overturning is reduced.
To illustrate the force applied to the rubber mount 400, as described above, the damping rubber ring 1023 is provided outside the boot of the upper mount plate and inside the limit stop 1017. The damping rubber ring 1023 may be secured to the ring upper outer surface of the upper seat plate boot. When there are horizontal and vertical vibrations of the substructure 200, the vibrations are transmitted through the following paths: the lower structure 200 → the rubber laminate 1019 → the vibration-damping rubber ring 1023 → the limit baffle 1017 → the rubber mount upper buried plate 1003 → the upper structure 100, and the amplitude of horizontal and vertical vibration transmitted from the lower structure 200 to the upper structure 100 is reduced due to the vibration-damping rubber ring 1023.
When the upper structure 100 receives a horizontal load (wind load, earthquake action, or the like), the horizontal load transmission path of the upper structure 100 is: the upper structure 100 → the rubber support upper buried plate 1003 → the limit baffle 1017 → the damping rubber ring 1023 → the rubber laminate 1019 → the lower structure 200, and the reliable transmission of the horizontal force is realized. Meanwhile, as the total horizontal rigidity of the rubber laminated layer 1019 (natural rubber or lead rubber) is limited, the horizontal rigidity of the structure can be reduced, the horizontal earthquake action can be reduced, and horizontal shock insulation can be realized.
When the upper structure 100 is subjected to vertical pressure (when the earthquake action is large), the vertical pressure transmission path of the upper structure 100 is: the upper structure 100 → the rubber mount upper buried plate 1003 → the cushion rubber 1020 → the upper mount plate boot → the rubber laminate 1019 → the lower structure 200, and reliable transmission of the vertical pressure is achieved.
Because the shoe cap of the upper support plate can have a considerable height, a larger contact area and a larger height can be arranged between the shoe cap of the upper support plate and the damping rubber ring 1023 and between the damping rubber ring 1023 and the limit baffle 1017 so as to transmit horizontal force. When the rubber laminate 1019 bears horizontal load and generates secondary bending moment, resisting moment is formed at the upper end and the lower end of the left side and the right side of the upper support plate boot cap, and when the rubber laminate 1019 is subjected to large horizontal deformation, the two pressed areas form resisting moment, so that the rubber laminate 1019 of the rubber support 400 is prevented from bearing excessive tensile force at the outer side.
The rubber mount 400 and the horizontally slidable vertical vibration-damping mount 300 are juxtaposed between the upper structure 100 and the lower structure 200 in the building, and a plurality of pieces may be disposed to form a vibration-isolating layer in the building structure. Fig. 3A and 3B are schematic diagrams of an arrangement of a plurality of rubber mounts 400 and a horizontally slidable vertical damping mount 300 in an embodiment of the present invention, in which white circles indicate the horizontally slidable vertical damping mount 300 and black dots indicate the rubber mounts 400. As shown in fig. 3A, the rubber mount 400 is disposed at the peripheral region of the seismic isolation layer to improve torsional rigidity of the seismic isolation layer; it may be a uniform arrangement as shown in fig. 3B, one form of uniform arrangement being shown in fig. 3B, or it may be uniform in other regular ways.
FIG. 4 is a schematic view of a rubber mount 400 in a building structure juxtaposed with a horizontally slidable vertical vibration dampening mount 300 according to an embodiment of the present invention. As before, the rubber mount 400 is not vertically loaded, so a second gap S may be provided between the cushion rubber pad 1020 and the rubber mount upper buried plate 1003; or the two are in contact without pressure, but the mode is not easy to master during construction. In general, during construction, the vertical damping mount 300 capable of sliding horizontally is required to be installed firstly, and the rubber mount 400 not bearing vertically is required to be installed later (under the condition that construction allows, the installation is delayed as much as possible). The purpose is as follows: before the rubber support 400 which is not vertically loaded is installed, the vertical deformation of the vertical load of the structure is basically completed, and the rubber support 400 still does not bear the vertical load when the structure bears the subsequent vertical load (such as decoration load and live load). As shown in fig. 5A and 5B, fig. 5A and 5B are partial schematic views of a vertically non-bearing rubber mount 400 according to an embodiment of the present invention, wherein before bearing (i.e., before the structure bears a subsequent vertical load), a second gap S is formed between the upper rubber mount plate 1003 and the vibration-damping rubber pad 1020, and after the subsequent vertical load is applied, a compressive deformation D is generated, so that the original larger gap S becomes smaller, but a gap is still required to exist, so that when the second gap S between the vibration-damping rubber pad 1020 and the upper buried plate 1003 is reserved, the size of the second gap S needs to satisfy the requirement that the rubber mount 400 is not vertically loaded under normal use, and can bear a vertical pressure load or a pulling load only under the action of an earthquake.
According to the technical scheme of the embodiment of the utility model, the vertical vibration damping support 300 capable of sliding horizontally can realize larger horizontal displacement while meeting the requirement of vertical vibration damping, and provides a foundation for realizing vibration isolation. Because the friction coefficient between the sliding material 1015 and the mirror surface stainless steel plate 1016 is small, generally about 0.02-0.05, and the borne horizontal force is small, when the vertical vibration damping support 300 capable of horizontally sliding bears a large horizontal load such as earthquake action, the vertical vibration damping support 300 slides, and the horizontal deformation is transmitted to the spring connecting plate by the spring sleeve. The rubber mount 400 which is not vertically loaded does not bear a vertical load because the second gap S exists between the vibration damping rubber pad 1020 and the upper buried plate 1003. Because the total horizontal rigidity of the vertical vibration-damping support 300 and the rubber support 400 (natural rubber support or lead rubber support) which can slide horizontally is limited, the horizontal rigidity of the structure can be reduced, the horizontal earthquake action can be reduced, and horizontal shock insulation can be realized. According to the displacement condition of the seismic isolation layer, the additional arrangement of a damper can be considered.
The above-described embodiments should not be construed as limiting the scope of the utility model. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
