Detailed Description
The structure and effect of the rubber mount for construction (hereinafter simply referred to as "rubber mount") according to the embodiment of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a state of a rubber support installed in a building structure according to an embodiment of the present invention, fig. 2 is a partial schematic diagram of a rubber support in a vertical bearing state according to an embodiment of the present invention, and fig. 3 is a partial schematic diagram of a rubber support in a normal use state according to an embodiment of the present invention. The above-mentioned detail is indicated by the circle a in fig. 1, where the states of fig. 1 and 2 are different, and fig. 2 shows the compression deformation. Fig. 4 is an assembly schematic of a rubber mount into a building structure according to an embodiment of the present invention.
As shown in fig. 1 to 4, a rubber mount is provided between an upper structure 1100 and a lower structure 1200 of a building, and a buried plate 1002 on the mount is connected to the upper structure 1100 by a bolt 1018. The outer limit ring plate 1013 is a cylindrical surface, the axial direction of which is perpendicular to the embedded plate 1002 on the support, and the two are welded with each other. The inner space of the outer retainer plate 1013 houses an upper seat plate boot 1005 having a damping material such as a damping rubber ring 1006 filled therebetween, and the damping rubber ring 1006 may be fixed to the outer surface of the upper seat plate boot ring plate 1011 or the inner surface of the outer retainer plate 1013. Between the upper seat plate bonnet top plate 1012 and the seat upper counter plate 1002 is a damping material such as a damping rubber pad 1008, the damping rubber pad 1008 being secured to the upper surface of the upper seat plate bonnet top plate 1012.
The upper support plate boot 1005 is similar to a oblate box in shape, and is sequentially provided with an upper support plate 1009, an upper support plate boot ring plate 1011, a top plate 1012 and a vibration damping rubber pad 1008 from bottom to top, which respectively correspond to the lower bottom surface, the side surface and the upper bottom surface of the oblate box. That is, the upper support plate boot ring plate 1011 is a cylindrical surface and has a positional relationship with the outer limit ring plate 1013 as inner and outer rings. Namely an upper support plate boot ring plate 1011, a damping rubber ring 1006 and an outer limit ring plate 1013 are arranged from inside to outside in sequence, and it can be seen that there is no fixed connection between the support plate boot ring plate 1011 and the outer limit ring plate 1013, that is, the two can be vertically separated.
The support plate boot ring plate 1011 and the outer limit ring plate 1013 have ribs as reinforcement, as shown in fig. 5, fig. 5 is a schematic plan view of the upper support plate boot 1005 and the outer limit baffle 1007 according to an embodiment of the present invention, in which a plurality of inner stiffener 1010 and outer stiffener 1014 are shown as ribs and circumferentially distributed.
The upper support plate 1009 is attached to the laminated rubber 1001 by bolts 1018 or other means, and the upper plate 1012 is not in contact with the support upper buried plate 1002 in the normal use state and when assembled, i.e., with a clearance 1015 (shown in fig. 4) therebetween. That is, under normal use conditions, the rubber mount is not subjected to vertical forces that are borne by other mounts, such as spring isolators. When the vertical deformation of superstructure 1100 exceeded reservation clearance 1015, reached vertical bearing state, the support buried plate 1002 contacted with the damping rubber pad 1008 at upper bracket board boots cap 1005 top this moment, along with damping rubber pad 1008 is constantly compressed, superstructure 1100's vertical pressure down transmits the rubber support on, reaches the purpose that vertical spacing and pressurized were born under extreme condition.
Hereinafter, the stress of the rubber support will be described with reference to fig. 6, and fig. 6 is a schematic view of a state of the rubber support when a horizontal force is applied thereto according to the embodiment of the present invention. As explained above, outside the upper seat plate boot 1005, inside the limit baffle 1007 is a damping rubber ring 1006. A damping rubber ring 1006 may be secured to the ring upper outer surface of the upper seat plate boot 1005. When there are horizontal and vertical vibrations of the lower structure 1200, the vibrations are transmitted through the following paths: lower structure 1200 → rubber mount → damping rubber ring 1006 → limit stop 1007 → buried plate on mount 1002 → upper structure 1100, the horizontal and vertical vibration amplitudes transmitted from lower structure 1200 to upper structure 1100 are reduced due to damping rubber ring 1006.
When the superstructure 1100 is subjected to horizontal loads (wind loads, seismic action, etc.), the horizontal load transmission path of the superstructure 1100 is: the upper structure 1100 → the embedded plate 1002 on the support → the limit baffle 1007 → the damping rubber ring 1006 → the rubber support → the lower structure 1200, and the reliable transmission of the horizontal force is realized. Meanwhile, as the total horizontal rigidity of the rubber support (a natural rubber support or a lead core rubber support) 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 1100 is subjected to vertical pressure (when the seismic action is large), the vertical pressure transmission path of the upper structure 1100 is: the upper structure 1100 → the buried plate on the support 1002 → the cushion rubber pad 1008 → the upper seat plate shoe cap 1005 → the rubber support → the lower structure 1200, and reliable transmission of the vertical pressure is achieved.
Because the upper seat plate boot 1005 can have a considerable height, a larger contact area and a larger height can be provided between the upper seat plate boot 1005 and the damping rubber ring 1006 and between the damping rubber ring 1006 and the limit baffle 1007 to transmit horizontal force. When the rubber support bears a secondary bending moment generated by horizontal load, 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 1005, as shown in fig. 6, when the rubber lamination generates large horizontal deformation, two compression areas form resisting moment, which is helpful for preventing the outer side of the rubber support part of the rubber support from bearing excessive tensile force.
The above detailed description does not limit the scope of the present invention. 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.
