Description

Technical Field

[0001] This application relates to the field of upper support pier structures, and more specifically, to an upper support pier structure for seismic isolation and reinforcement of existing buildings. Background Technology

[0002] Seismic isolation and reinforcement of existing buildings typically requires the installation of a seismic isolation layer at the building's base. Current techniques involve: first, removing the load-bearing frame columns from the top of the foundation to the height of the first-floor roof; installing lower supports or columns under the seismic isolation bearings; installing upper supports or columns above the seismic isolation bearings; and then constructing a reinforced concrete rigid floor slab within the plane of the upper supports. However, current upper support structures for seismic isolation reinforcement of existing buildings mostly rely on pre-embedded reinforcing bars and concrete pouring to fix the seismic isolation base. This results in poor overall connection between the seismic isolation base and the ground supports, making them prone to displacement and slippage under stress. Therefore, a new upper support structure for seismic isolation reinforcement of existing buildings is needed to address this issue. Utility Model Content

[0003] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0004] To address the technical problems mentioned in the background section above, some embodiments of this application provide an upper support structure for seismic isolation and reinforcement of existing buildings, including a support structure, with a support component installed between two support structures; the support component includes a connector cast inside the support structure, and an installation cavity is provided on one side of the support structure adjacent to the support component.

[0005] A fixing plate is embedded in the mounting cavity, and a mounting base is installed between the two fixing plates. The fixing plates are connected to the connector and the mounting base by fixing bolts, and a rubber vibration isolation base is installed between the two mounting bases.

[0006] Furthermore, the connector includes an anchor cylinder, which is pre-embedded inside the support structure. A baffle plate is fitted onto the anchor cylinder, and a protruding ring is fitted onto one end of the anchor cylinder facing the fixing plate. The anchor cylinder has threaded holes for fixing bolts.

[0007] Furthermore, the baffle plate is disc-shaped, and a plurality of baffle plates are provided, which are equidistantly arranged on the anchor cylinder.

[0008] Furthermore, a tensioning member is fixed at the bottom of the anchor cylinder, and the two tensioning members are connected and fixed together by an extension rod.

[0009] Furthermore, several extension rods are provided, and the tensioning member and several extension rods are pre-embedded in a mesh pattern inside the support structure.

[0010] Furthermore, fixing holes are provided at the four corners of the fixing plate and the mounting base, and fixing bolts are installed through the fixing holes.

[0011] Furthermore, a positioning hole is drilled at the edge of the mounting base, and a positioning post is protruding from one side of the fixing plate facing the mounting base, and the positioning hole and the positioning post are fitted together.

[0012] Furthermore, a plurality of positioning holes are provided, and the plurality of positioning holes are symmetrically arranged on the mounting base; a plurality of positioning posts are provided, and the plurality of positioning posts are symmetrically arranged on the fixing plate.

[0013] The beneficial effects of this application are as follows: It provides an upper support structure for seismic isolation reinforcement of existing buildings. Through the connectors, mesh tensioners, and extension rods pre-embedded inside the support structure, during operation, since a large part of the support component is connected to the inside of the support structure, it can ensure uniform force distribution as much as possible, and avoid the overall deflection of the rubber seismic isolation seat when under tension, and avoid slippage when bearing load. Through the support component composed of rubber seismic isolation seat, fixing plate, connectors, and fixing bolts, the rubber seismic isolation seat can be replaced by disassembly after long-term use if it is damaged. This avoids the situation where the rubber seismic isolation seat is fixed by pre-embedded fixing steel bars and concrete pouring, which makes it inconvenient to disassemble and replace the rubber seismic isolation seat later.

[0026] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] This specific implementation method is a superstructure for seismic isolation and reinforcement of existing buildings, such as... Figure 1-4As shown, the upper support structure for the seismic isolation reinforcement of the existing building includes a support structure 1, a support component 2 installed between two support structures 1, and a connector 10 cast inside the support structure 1. An installation cavity 9 is opened on the side of the support structure 1 adjacent to the support component 2. A fixing plate 6 is embedded in the installation cavity 9. An installation seat 3 is installed between two fixing plates 6. The fixing plate 6 is connected to the connector 10 and the installation seat 3 by fixing bolts 8. A rubber seismic isolation seat 4 is installed between two installation seats 3. Fixing holes 61 are opened at the four corners of the fixing plate 6 and the installation seat 3. Fixing bolts 8 are installed through the fixing holes 61.

[0028] The support assembly 2, consisting of rubber vibration isolation seat 4, fixing plate 6, connector 10, and fixing bolts 8, allows the rubber vibration isolation seat 4 to be replaced after prolonged use if it becomes damaged. This avoids situations where the rubber vibration isolation seat 4 is fixed by pre-embedded steel bars and concrete pouring, making it difficult to disassemble and replace later.

[0029] The aforementioned connector 10 includes an anchor cylinder 12, which is embedded inside the pier structure 1. A baffle plate 13 is fitted onto the anchor cylinder 12. The baffle plate 13 is disc-shaped and there are several baffle plates 13. The several baffle plates 13 are equidistantly arranged on the anchor cylinder 12. A protruding ring 11 is fitted and fixed to one end of the anchor cylinder 12 facing the fixing plate 6. The anchor cylinder 12 has threaded holes 111 for fixing bolts 8. A tensioning member 14 is fixed at the bottom of the anchor cylinder 12. Two tensioning members 14 are connected and fixed by extension rods 15. There are several extension rods 15. The tensioning members 14 and the several extension rods 15 are embedded in the pier structure 1 in a mesh pattern. The mesh pattern between the tensioning members 14 and the several extension rods 15 can enhance the structural stability, prevent concrete cracking, and improve seismic performance while ensuring stress resistance.

[0030] By using the connectors 10, mesh tensioners 14, and extension rods 15 pre-embedded inside the support structure 1, the support components 2 can be connected to the inside of the support structure 1 during operation. This ensures that the force is evenly distributed when under stress, avoids situations such as the overall deflection of the rubber isolation seat 4 when under tension, and minimizes the risk of slippage when bearing loads.

[0031] The mounting base 3 has a positioning hole 5 drilled at its edge. The fixing plate 6 has a positioning post 7 protruding from one side facing the mounting base 3. The positioning hole 5 and the positioning post 7 are connected by insertion. There are several positioning holes 5, which are symmetrically arranged on the mounting base 3. There are also several positioning posts 7, which are symmetrically arranged on the fixing plate 6.

[0032] By cooperating with the positioning holes 5 and positioning posts 7, the mounting base 3 can be stably locked and fixed in the corresponding position when it is installed with the fixing plate 6, thus avoiding misalignment of the mounting base 3 during operation.

[0033] Working principle:

[0034] During operation, the tensioning member 14, the extension rod 15, and the connecting member 10 are pre-embedded inside the support structure 1. The fixing plate 6 is snapped into the mounting cavity 9. The positioning hole 5 on the mounting base 3 is engaged with the positioning post 7 on the fixing plate 6 to complete the initial positioning of the mounting base 3 and the fixing plate 6. The fixing bolt 8 is then engaged with the fixing hole 61, and the fixing bolt 8 is threaded into the threaded hole 111 to complete the overall positioning and fastening of different components of the support assembly 2.

[0035] During operation, the mesh-like tensioning member 14, the extension rod 15, and the connecting member 10 work together to ensure uniform force distribution at all locations of the support structure 1 when tension is applied. The above description is merely an explanation of some preferred embodiments of this disclosure and the principles of the applied technology. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
