[0002] Rubber bearings refer to supporting components used to support the weight of containers or equipment and fix them in a certain position. They also have to withstand vibration and seismic loads during operation. Commonly used ones are plate rubber bearings. Plate rubber bearings are a type of bridge bearing product made of multiple layers of natural rubber and at least two layers of thin steel plates of the same thickness inlaid, bonded, and vulcanized. They are important structural components in current construction. The reasonable addition of seismic isolation bearings can effectively reduce the damage to buildings caused by earthquakes and greatly reduce the loss of people's lives and property. It is an effective measure and advanced technical means for earthquake resistance and disaster prevention in recent years.

[0003] The rubber bearings used in existing building structures have rubber layers and steel plate layers bonded together only by adhesives, and the bonding quality between the rubber layer and the steel plate layer is poor, which leads to weak tensile strength and short service life of the rubber isolation bearings, as well as low lateral stress bearing capacity, posing a safety hazard. Therefore, we propose a tensile isolation rubber bearing. Utility Model Content

[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Please refer to Figures 1 to 3 , the embodiments provided by the utility model are:

[0024] A tensile seismic isolation rubber bearing comprises a bearing plate 1, a seismic isolation pile core 2 and a tensile outer pile 3. There are two bearing plates 1, which are symmetrically arranged up and down. The two bearing plates 1 are fixedly connected to the upper and lower ends of the seismic isolation pile core 2, respectively. The middle part of the seismic isolation pile core 2 is cylindrical, and the tensile outer pile 3 wraps the middle part of the seismic isolation pile core 2. The tensile outer pile 3 comprises an outer pile frame 301, an inner cross layer frame 302, a filling seam 303, a rubber filling layer 304 and a connecting cross frame 305. The outer pile frame 301 is in the shape of a hollow circular ring column, and the inner cross layer frame 302 is connected between the two side walls of the outer pile frame 301. The filling seam 303 is opened between the outer pile frame 301 and the seismic isolation pile core 2, and the inside of the filling seam 303 is filled with the rubber filling layer 304, and the connecting cross frame 305 is connected between the outer pile frame 301 and the seismic isolation pile core 2.

[0025] During the installation process of this rubber bearing used in a building structure, it can be positioned and supported by the bearing plate 1 set at the top and bottom of this rubber bearing. The outer side of the isolation pile core 2 is wrapped with a tensile outer pile 3. The tensile outer pile 3 has the characteristics of strengthening the structural strength of the isolation pile core 2 and improving its tensile performance. Specifically, in the tensile outer pile 3, an outer pile frame 301, an inner cross frame 302 and a connecting cross frame 305 are provided to improve the structural strength. The outer pile frame 301 is a hollow circular columnar structure, which can play the role of strengthening the vertical support force stability of the isolation rubber bearing. An inner cross frame 302 is provided in the outer pile frame 301 to improve the vertical and lateral support force stability of the outer pile frame 301, wherein the vertical refers to the direction parallel to the central axis of the isolation pile core 2 and the direction parallel to the bottom diameter or radius of the isolation pile core 2. In the outer pile frame A connecting cross frame 305 is provided between 30 and the seismic isolation pile core 2 to further improve the vertical and lateral support force stability of the seismic isolation rubber bearing as a whole, that is, to improve the tensile capacity of the seismic isolation rubber bearing. In addition, a rubber filling layer 304 is filled in the filling seam 303 between the outer pile frame 301 and the seismic isolation pile core 2. The seismic isolation pile core 2 itself is made of rubber material, which ensures the seismic resistance of the seismic isolation rubber bearing. The seismic isolation rubber bearing in the present application increases the internal structural strength as a whole, and further improves the stability of the tensile isolation process.

[0026] Specifically, the inner cross frame 302 is a cross grid structure frame. The connecting cross frame 305 is also a cross grid structure frame.

[0027] Furthermore, the inner cross-layer frames 302 are arranged in a circumferential array between the two side walls of the outer pile frame 301, and the top and bottom ends of the outer pile frame 301 are connected to the seismic isolation pile core 2, so that the bearing capacity of the seismic isolation rubber bearing in the circumferential direction is uniform.

[0028] Furthermore, the connecting cross frame 305 is provided in a circumferential array between the outer pile frame 301 and the seismic isolation pile core 2, so that the bearing capacity of the seismic isolation rubber bearing in the circumferential direction is uniform.

[0029] Furthermore, the seismic isolation pile core 2 includes a pile core rod 203 and a rubber pile 204 wrapping the pile core rod 203, the tensile outer pile 3 wraps the rubber pile 204, and the connecting cross frame 305 is connected between the outer pile frame 301 and the pile core rod 203. Here, the connecting cross frame 305 is further extended to the outer side wall of the pile core rod 203 in the transverse direction, so that the connecting cross frame 305 is also provided within the range where the rubber pile 204 of the seismic isolation pile core 2 is located, and the connecting cross frame 305 and the rubber pile 204 are connected as a whole after the rubber pile 204 is cast, thereby further improving the vertical and transverse support force stability of the seismic isolation rubber bearing.

[0030] Furthermore, the pile core rod 203 and the rubber pile 204 are integrally connected, so that the overall structural stability of the seismic isolation pile core 2 is good. In addition, because the connecting cross frame 305 is evenly distributed around the rubber pile 204, the central structural strength and uniform force stability of the seismic isolation rubber bearing are improved as a whole.

[0031] Preferably, the pile core rod 203 is made of butyl rubber.

[0032] Furthermore, the seismic isolation pile core 2 also includes a disc-shaped connecting piece 201 and a through hole 202 arranged at the center of the connecting piece 201. There are two connecting pieces 201, and the two ends of the pile core rod 203 are respectively inserted into the through hole 202 of one of the connecting pieces 201. The bearing plate 1 includes a bearing flange 101, and the connecting piece 201 is fixed on the bearing flange 101. In this rubber bearing, the two ends of the pile core rod 203 are respectively connected to a connecting piece 201, and the connecting piece 201 maintains a stable connection with the bearing flange 101, thereby improving the overall structural strength of the rubber bearing center, maintaining the stability of the compression and buffering process, and reducing deformation.

[0033] Furthermore, the connecting piece 201 is fixedly connected to the support flange 101, and the structure has good stability.

[0034] Furthermore, the support flange 101 is provided with placement holes 103. The seismic isolation rubber support is installed on the building through the placement holes 103 around the support flange 101 and the screws for positioning.

[0035] Furthermore, the bearing plate 1 also includes two anti-skid pads 102, which are fixed on the outer surfaces of both ends of the seismic isolation pile core 2. The seismic isolation rubber bearing is placed at the location of the installed building structure, and then the soft rubber anti-skid pad 102 on the top surface of the bearing flange 101 is fitted with the surface of the building structure. The bearing flange 101 maintains the stability of the friction force during the fitting process through the soft rubber anti-skid pad 102, and then cooperates with the placement hole 103 for positioning, thereby maintaining the stability of the support and seismic buffering process.

[0036] Furthermore, a flange 205 extending into the filling seam 303 is provided on the inner side of the connecting piece 201. The flange 205 enhances the connection stability between the connecting piece 201 and the tensile outer pile 3.

[0037] Working principle: First, support and position the seismic isolation rubber bearing through the support flange 101 installed at the top and bottom ends, place the seismic isolation rubber bearing at the location of the building structure, and then fit the soft rubber anti-slip layer 102 on the top surface of the support flange 101 with the surface of the building structure, and position and install it through the installation holes 103 and screws on all sides. The middle part of the seismic isolation pile core 2 is connected to the connecting piece 201 through the pile core rod 203, and the connecting piece 201 maintains a stable connection with the support flange 101. The pile core rod 203 is made of butyl rubber, and the pile core rod 203 is connected to the outer pile frame 301 through the connecting cross frames 305 distributed all around to form a whole. The two side walls of the hollow circular columnar outer pile frame 301 are connected to form a whole through the inner cross layer frame 302, thereby maintaining the integrity of the internal structure of the whole rubber bearing and maintaining the stability of the compression and buffering process.

[0038] In summary, the tensile-isolation rubber bearing provided by the utility model connects the outer wall of the pile core rod 203 and the inner wall of the outer pile frame 301 to form a whole through the connecting cross frames 305 distributed all around, thereby maintaining the integrity of the internal structure of the overall isolation rubber bearing, and the filling seam 303 inside the outer pile frame 301 is filled with a filling layer 304 made of natural rubber material to increase the internal layer quality, and the distributed connecting cross frames 305 made of butyl rubber material buffer the lateral force and tension, and the longitudinal force is improved through the hollow circular columnar outer pile frame 301, and the lateral force and tensile resistance of the outer pile frame 301 are improved through the inner cross layer frame 302, thereby increasing the internal structural strength and further improving the stability of the tensile-isolation process.
