Description

Technical Field

[0001] The present invention belongs to the technical field of vibration control and is applicable to the field of building structure base isolation; specifically, it is a rigid waterproof isolation bearing platform and its implementation method. Background Art

[0002] To solve the vibration impact of rail transit on the superstructure, laying a flexible pad at the bottom layer of the building is currently a relatively low-cost method. However, due to the need to ensure the safety and reliability of the building, the wall columns and foundation bearing platform at the bottom layer of the structure still adopt fixed connections, and only a flexible pad can be laid on the bottom floor slab, so that the vibration effect can still be transmitted to the superstructure through the transmission route of pile foundation - bearing platform - structural wall columns, and the isolation effect is greatly reduced or even ineffective.

[0003] Chinese Patent Application CN117071624A discloses an energy-dissipating vibration-reducing enlarged-body precast pile and its connection method with the superstructure. The energy-dissipating vibration-reducing enlarged-body precast pile consists of an upper energy-dissipating vibration-reducing area and a lower bearing area, and a through precast pile is provided at the central axis of the two areas; the upper energy-dissipating vibration-reducing area consists of a precast pile and a modified furan resin rubber concrete and a corrugated steel sleeve concentrically wrapped around it; the lower bearing area consists of a precast pile and a cementitious material concentrically wrapped around it. The energy-dissipating vibration-reducing enlarged-body precast pile is upwardly embedded in the superstructure, and the top of the pile and the superstructure are transitionally connected through a lower rubber pad, a sliding layer, an upper rubber pad, a steel sleeve top plate and steel anchor bolts, so as to achieve vibration reduction and isolation between the pile foundation and the superstructure. The structure is simple and the action mechanism is clear, which can greatly improve the anti-vibration performance of the pile foundation and the superstructure. In this prior art, due to the existence of a rigid connection structure between the structures, the isolation effect will still produce a transmission effect along the rigid connection structure, resulting in a weakened isolation effect. Moreover, in its technical solution, there is no protection and limitation structure for horizontal displacement.

[0004] It can be seen that how to adopt more effective, safe and low-cost measures to solve the above problems on the premise of ensuring the isolation effect has become a key and difficult point in the field of building structure vibration control. Summary of the Invention

[0014] Working principle of the present invention: The structural columns or structural wall columns on the pile cap and their upper parts are separated from the vibration source through the surrounding arrangement structure of vibration isolation elastic pads to achieve vibration isolation; these vibration isolation elastic pads can be made of various elastic materials that meet the requirements of vibration isolation, such as rubber pads, polyurethane pads, rubber bearings, springs, etc., and have built-in damping. A pit is processed on the pile cap, the structural column or structural wall column is placed in the pit, and vibration isolation is achieved by setting vibration isolation elastic pads between the structural wall column and the pit. At the same time, the structural design of the pit is combined with the use of tensile bolts to vertically connect the structural wall column and the pile cap to limit its horizontal displacement and prevent the separation of the wall column and the pile cap. In this structural design: The structural column and the pile cap are completely isolated. By using elastic isolation pads, side elastic pads, and bottom elastic pads, the structural column with an enlarged column head at the lower end is completely isolated from the pit of the pile cap where it is located, effectively restricting the vibration transmission between the two. The tensile bolts pass through the enlarged column head, the second bottom elastic pad, and the pile cap to connect the pile cap and the structural column and form a tensile structure; In order to further improve the vibration isolation effect, embedded steel plates are also used. Sleeves are designed to be arranged downward on the embedded steel plates, elastic cylinders are installed in the hole walls, and bolt elastic pads are set at the top of the tensile bolts, thus achieving a completely isolated structure; Among them, the sleeve uses an upper and lower double-section structure, realizing the non-rigid direct connection structure of the anchor reinforcement and the tensile bolt, further improving the vibration isolation effect; In the structure of the present invention, not only isolation elastic pads are provided between the structural column and the pile cap, but also elastic pads are used for isolation treatment between the bottom plate and the pile cap, between the bottom plate and the underlying soil, between the pressing member and the structural column and the pile cap, and between the bottom surface of the enlarged column head and the embedded steel plate, further reducing the vibration transmission between components. In a specific structure, for the outer side of the pile cap being a two-step structure up and down, the elastic pad arrangement between the steps, the bottom plate and the underlying soil is also designed, so that a well-defined vibration isolation system is formed between the bottom plate, the pile cap and the soil cover. The present invention uses elastic isolation pads to completely isolate the structural column from the pile cap, the bottom plate from the pile cap and the underlying soil, and with the tensile structure formed by tensile bolts, while manufacturing a building vibration isolation structure with excellent vibration isolation performance, it also has excellent support and tensile performance, comprehensively and fully improving the vibration isolation performance and stability of the building.

[0015] Beneficial technical effects of the present invention compared with the prior art: (1) Simple construction: The setting of the vibration isolation elastic pads is convenient, the construction process is simple, and it does not affect the construction period; (2) Good vibration isolation effect: Through the all-round elastic isolation method, the structural column is isolated from the pile cap, the bottom plate is isolated from the pile cap and the underlying soil to achieve flexible contact, effectively preventing the transmission of vibration, improving the anti-vibration performance of the building.

While isolating vibrations, it has stable and reliable force support and limiting force, which can effectively prevent horizontal displacement or disengagement.

Detailed implementation method

[0018] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0019] Embodiment 1: As Figures 1-7 shown, a rigid waterproof and vibration isolation bearing platform mainly relates to the vibration isolation method of the bottom plate 2, the structural column 1 and the above structures. The vibration isolation between the structural column 1 and the bearing platform 3 is mainly achieved through elastic pads, and the tensile effect between the structural column 1 and the bearing platform 3 is achieved by using the tensile bolt 9.

[0020] The lower end of the structural column 1 is an enlarged column head, and a through first countersunk hole is machined downward on the enlarged column head, and the countersunk end is on the top surface.

[0021] The lower end of the bearing platform 3 is supported by the foundation pile 4. There is a first concave pit on the upper plane of the bearing platform 3. The bottom surface of the first concave pit is provided with a pre-embedded steel plate 8. A second bottom elastic pad 7 is placed on the pre-embedded steel plate 8. The enlarged column head of the structural column 1 is embedded in the first concave pit of the bearing platform 3 and placed on the second bottom elastic pad 7. The first side elastic pad 6 is arranged between the side wall of the enlarged column head of the structural column 1 and the side wall of the first concave pit. Thus, the structural column 1 and the bearing platform 3 are completely isolated.

[0022] A first through hole is processed at the center of the pre-embedded steel plate 8. The first through hole is used for vibrating the concrete. At the same time, the pre-embedded steel plate 8 is processed with corresponding second through holes at the positions of the first counterbore holes of the enlarged column head of the corresponding structural column 1. A sleeve 13 is arranged below the second through hole. The upper end of the sleeve 13 is processed with a first threaded hole corresponding to the tensile bolt. The lower end is processed with a second bolt hole corresponding to the anchor reinforcement 14. The upper end of the anchor reinforcement 14 is processed with an external thread, and the anchor reinforcement 14 is threadedly connected to the lower end of the sleeve 13.

[0023] Both the sleeve 13 and the anchor reinforcement 14 are pre-embedded in the bearing platform 3.

[0024] An elastic cylinder 12 is arranged on the side wall of the through hole of the first counterbore hole of the structural column 1; a bolt elastic pad 11 is arranged at the bottom of the counterbore part of the first counterbore hole.

[0025] The tensile bolt 9 is installed from above the first counterbore hole of the structural column 1 downward, passes through the structural column 1, the second bottom elastic pad 7 and the pre-embedded steel plate 8, and is screwed on the upper end of the sleeve 13. A steel gasket 10 is arranged between the tensile bolt 9 and the bolt elastic pad 11. Since the vibration isolation between the tensile bolt 9 and the enlarged column head of the structural column 1 is achieved through the bolt elastic pad 11 and the elastic cylinder 12, the vibration effect of the bearing platform 3 will not be transmitted to the structural column 1 through the sleeve tensile bolt 9.

[0026] An outer cover 20 is also placed on each first counterbore hole of the structural column 1.

[0027] The height of the underlying soil 19 outside the bearing platform 3 is flush with the upper plane of the bearing platform 3. The bottom plate 2 is directly arranged on the bearing platform 3 and the underlying soil 19. One end of it is supported on the upper plane of the bearing platform 3 and is cast as a whole with the bearing platform 3. The side surface of the bottom plate 2 and the side surface of the enlarged column head of the structural column 1 still achieve vibration isolation through the first side elastic pad 6. In this embodiment, the materials of the first bottom elastic pad 5, the first side elastic pad 6, the second bottom elastic pad 7, the bolt elastic pad 11, and the elastic cylinder 12 are all elastic materials that can isolate vibration. At the same time, the setting method of the bottom plate 2 is based on no vibration isolation requirement.

[0028] In this embodiment, under seismic action, the concave pit of the bearing platform 3 and the bottom plate 2 will limit the horizontal displacement of the structural column 1, and the tensile bolts 9 can effectively limit the relative separation between the structural column 1 and the bearing platform 3.

[0029] Embodiment 2: As Figures 8-9 shown, a rigid waterproof vibration isolation bearing platform and its implementation method can also be realized in the following way: When the bottom plate 2 has a vibration isolation requirement: The first bottom elastic pad 5 is arranged on the upper planes of the bearing platform 3 and the underlying soil cover 19. The bottom plate 2 is arranged above the first bottom elastic pad 5. One end of the bottom plate 2 is supported on the upper plane of the bearing platform 3, and the bottom plate 2 and the enlarged column head of the structural column 1 are cast into a whole.

[0030] Thus, the complete vibration isolation between the structural column 1 and the bottom plate 2 and the bearing platform 3 is achieved.

[0031] In this embodiment, the materials of the first bottom elastic pad 5, the first side elastic pad 6, and the second bottom elastic pad 7 mentioned are all elastic materials that can isolate vibration.

[0032] In this embodiment, under seismic action, the concave pit of the bearing platform 3 will limit the horizontal displacement of the structural column 1, and the pressing member 18 can effectively limit the relative separation between the structural column 1 and the bearing platform 3.

[0033] Embodiment 3: As Figures 10-12 shown, a rigid waterproof vibration isolation bearing platform and its implementation method can also be realized in the following way: Cancel the embedded steel plate 8, the tensile bolts 9, the steel washers 10, the bolt elastic washers 11, the elastic cylinder 12, the sleeve 13, and the anchor bars 14.

[0034] Cancel the first counterbore of the structural column 1.

[0035] The lower end of the structural column 1 is an enlarged column head; The lower end of the bearing platform 3 is supported by the foundation piles 4. There is a first concave pit on the upper plane of the bearing platform 3. The second bottom elastic pad 7 is placed on the bottom surface of the first concave pit. The enlarged column head of the structural column 1 is embedded in the first concave pit of the bearing platform 3 and placed above the second bottom elastic pad 7. The first side elastic pad 6 is arranged between the side wall of the enlarged column head of the structural column 1 and the side wall of the first concave pit.

[0036] The height of the underlying soil cover 19 outside the bearing platform 3 is flush with the upper plane of the bearing platform 3. The bottom plate 2 is directly arranged above the bearing platform 3 and the underlying soil cover 19. One end of it is supported on the upper plane of the bearing platform 3 and is cast into a whole with the bearing platform 3. The side surface of the bottom plate 2 and the side surface of the enlarged column head of the structural column 1 still achieve vibration isolation through the first side elastic pad 6.

[0037] On the upper plane of the enlarged column head of the structural column 1, a third bottom elastic pad 17 is also provided. The upper plane of the third bottom elastic pad 17 is at the same height as the upper plane of the bearing platform 3. Thus, the structural column 1 and the bearing platform 3 are completely isolated.

[0038] On the upper plane of the bearing platform 3, a pressing member 18 is fixedly installed. The inner side of the pressing member 18 floats on the upper plane of the third bottom elastic pad 17. At the same time, a second side elastic pad 15 is also provided between the pressing member 18 and the structural column 1 in the vertical direction.

[0039] Thus, the structural column 1 is completely vibration isolated from the bearing platform 3 and the pressing member 18.

[0040] In this embodiment, the materials of the first side elastic pad 6, the second bottom elastic pad 7, the second side elastic pad 15, and the third bottom elastic pad 17 mentioned are all elastic materials that can isolate vibration.

[0041] In this embodiment, under the action of an earthquake, the concave pit of the bearing platform 3 will limit the horizontal displacement of the structural column 1, and the pressing member 18 can effectively limit the relative separation between the structural column 1 and the bearing platform 3.

[0042] Embodiment 4: As Figures 13-14 shown, a rigid waterproof and vibration isolation bearing platform and its implementation method mainly achieve vibration isolation between the structural wall 21, the bottom plate 2, and the bearing platform 3 through elastic pads, and use tensile bolts 9 to achieve the tensile effect between the structural wall 21 and the bearing platform 3.

[0043] Taking Figure 13 the left side shown as the outside of the building structure and the right side as the inside of the building structure, the lower end of the structural wall 21 is an enlarged wall footing. Two rows of through second countersunk holes are processed on both sides of the enlarged wall footing from top to bottom, and the countersunk ends are on the top surface.

[0044] The lower end of the strip-shaped bearing platform 22 is supported by the foundation pile 4. There is a strip-shaped concave pit b on the upper plane of the strip-shaped bearing platform 22. An embedded steel plate 8 is provided on the bottom surface of the strip-shaped concave pit b. A second bottom elastic pad 7 is placed on the embedded steel plate 8. The enlarged wall footing of the structural wall 21 is embedded in the strip-shaped concave pit b of the strip-shaped bearing platform 22 and placed on the second bottom elastic pad 7. The first side elastic pad 6 is arranged between the side wall of the enlarged wall footing of the structural wall 21 and the side wall of the strip-shaped concave pit b. Thus, the structural wall 21 and the strip-shaped bearing platform 22 are completely isolated.

[0045] A through hole c is machined at the center of the embedded steel plate 8. The through hole c is used for vibrating the concrete. At the same time, through holes d corresponding to the second counterbore holes of the enlarged wall footing of the corresponding structural wall 21 are machined on the embedded steel plate 8. A sleeve 13 is arranged below the through hole d. A first threaded hole corresponding to the tensile bolt is machined at the upper end of the sleeve 13, and a second bolt hole corresponding to the anchor bar 14 is machined at the lower end. The upper end of the anchor bar 14 is machined with an external thread, and the anchor bar 14 is threadedly connected to the lower end of the sleeve 13.

[0046] Both the sleeve 13 and the anchor bar 14 are embedded in the strip-shaped bearing platform 22.

[0047] An elastic cylinder 12 is arranged on the side wall of the through hole of the second counterbore hole of the structural wall 21; a bolt spring washer 11 is arranged at the bottom of the counterbore part of the second counterbore hole.

[0048] The tensile bolt 9 is installed downward from above the second counterbore hole of the structural wall 21, passes through the structural wall 21, the second bottom spring washer 7 and the embedded steel plate 8, and is screwed onto the upper end of the sleeve 13. A steel washer 10 is arranged between the tensile bolt 9 and the bolt spring washer 11. Since the vibration between the tensile bolt 9 and the enlarged wall footing of the structural wall 21 is realized through the bolt spring washer 11 and the elastic cylinder 12, the vibration effect of the strip-shaped bearing platform 22 will not be transmitted to the structural wall 21 through the sleeve tensile bolt 9.

[0049] An outer cover 20 is also placed on each second counterbore hole of the structural wall 21.

[0050] On the inner side of the building structure, the height of the underlying soil 19 outside the strip-shaped bearing platform 22 is flush with the upper plane of the strip-shaped bearing platform 22. The floor slab 2 is arranged on the bearing platform 3 and the underlying soil 19. The side surface of the floor slab 2 is still vibration-isolated from the side surface of the enlarged column head of the structural column 1 through the first side spring washer 6.

[0051] As Figures 17-18 shown, if the floor slab 2 has vibration isolation requirements, the first bottom spring washer 5 is arranged on the upper planes of the strip-shaped bearing platform 22 and the underlying soil 19. The floor slab 2 is arranged above the first bottom spring washer 5. One end of it is supported on the upper plane of the strip-shaped bearing platform 22 and is cast integrally with the strip-shaped bearing platform 22. The side surface of the floor slab 2 is still vibration-isolated from the side surface of the enlarged column head of the structural column 1 through the first side spring washer 6.

[0052] On the outer side of the building structure, a fourth bottom spring washer 23 is arranged on the upper plane of the enlarged wall footing of the structural wall 21. A fourth side spring washer 24 is arranged on the outside of the structural wall 21. The side soil 25 and the structural wall 21 are vibration-isolated through the fourth bottom spring washer 23 and the fourth side spring washer 24.

[0053] In this embodiment, the materials of the first side spring pad 6, the second bottom spring pad 7, the bolt spring pad 11, the elastic cylinder 12, the fourth bottom spring pad 23 and the fourth side spring pad 24 mentioned are all elastic materials that can isolate vibration. At the same time, the setting method of the bottom plate 2 is based on the requirement of no vibration isolation.

[0054] Under the action of earthquake, the pits of the strip-shaped bearing platform 22 and the bottom plate 2 will limit the horizontal displacement of the structural wall 21, and the tensile bolts 9 can effectively limit the relative separation of the structural wall 21 and the strip-shaped bearing platform 22.

[0055] If the structural wall 21 is an internal wall of a building structure, the vibration isolation method thereof can refer to the method on the inner side of the building structure in this embodiment, that is, the vibration isolation methods are adopted on both sides of the structural wall 21.

[0056] Embodiment 5: As Figures 15-16 shown, a rigid waterproof and vibration isolation bearing platform and its implementation method cancel the embedded steel plate 8, the tensile bolts 9, the steel gaskets 10, the bolt spring pads 11, the elastic cylinders 12, the sleeves 13 and the anchor bars 14.

[0057] Cancel the second counterbore of the structural wall 21.

[0058] Taking Figure 16 the left side shown as the outside of the building structure and the right side as the inside of the building structure, the lower end of the structural wall 21 is an enlarged wall footing; The lower end of the strip-shaped bearing platform 22 is supported by the foundation piles 4. There are pits b on the upper plane of the strip-shaped bearing platform 22. The second bottom spring pad 7 is placed on the bottom surface of the pits b.
