Description

Technical Field

[0001] This utility model relates to the field of seismic isolation bearing technology, and in particular to a pre-embedded steel plate anchoring device for seismic isolation bearings. Background Technology

[0002] Bearing embedded plates are important connecting components in various engineering structures. They are usually made of steel plates and are pre-embedded in designated locations before concrete pouring. They serve as the connection medium between the superstructure and the foundation in structures such as bridges and buildings, uniformly transferring loads and distributing stress. They provide a stable and reliable installation foundation for the bearings, ensuring that the load-bearing and displacement requirements of the superstructure are met, and guaranteeing the safety and stability of the engineering structure during long-term use. They are widely used in transportation, construction, and many other fields.

[0003] Existing seismic isolation bearing pre-embedded steel plate anchoring devices typically involve welding the anchoring bars of the pre-embedded plate to the reinforcing bars in the concrete foundation before pouring concrete. While this anchors the pre-embedded steel plate, the lack of connection between the bottom ends of each anchoring bar means that when the structure is subjected to large loads or dynamic forces such as earthquakes, each anchoring bar bears stress independently, failing to form a coordinated working mechanism. This can easily lead to stress concentration, causing premature failure of some anchoring bars and reducing the overall anchoring effect of the device. Furthermore, the lack of bottom connecting components makes it difficult to quickly and accurately position and fix the anchoring bars during construction, increasing construction difficulty and time costs.

[0004] Therefore, it is necessary to develop a pre-embedded steel plate anchoring device for seismic isolation bearings to address the above-mentioned defects. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-embedded steel plate anchoring device for seismic isolation bearings, which can avoid the independent stress of each anchor bar, reduce stress concentration, improve the anchoring effect of the anchoring device, and at the same time, facilitate the positioning and fixing of the anchor bars, reducing time costs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses a pre-embedded steel plate anchoring device for seismic isolation bearings, comprising a pre-embedded steel plate, connecting components, and several anchor bars. The anchor bars are arranged in a rectangular array and their top ends are fixedly connected to the pre-embedded steel plate. Several connecting components are provided at the bottom ends of the anchor bars. The connecting components are fixedly connected to the main steel reinforcement frame of the foundation. The connecting components are used to connect and fix several anchor bars distributed in the same row.

[0008] Furthermore, the connecting assembly includes a connecting plate, which is formed by splicing two connecting strips; either of the two connecting strips is fixedly connected to the column reinforcement frame of the foundation; several semi-circular holes adapted to the anchor bars are opened on the side walls facing each other on both connecting strips; several anchor bars in the same row pass through several semi-circular holes on the two connecting strips one by one; and fixing assemblies are provided at both ends of the two connecting strips to fix them together.

[0009] Furthermore, the fixing component includes two semi-threaded columns, which can be spliced ​​together to form a complete threaded column. The two semi-threaded columns are respectively fixedly connected to one side wall of the two connecting strips, and a threaded cylinder is threadedly connected to the threaded column formed by splicing the two semi-threaded columns.

[0010] Furthermore, several fixing holes are symmetrically opened through the top surface of the two connecting strips at the connection point, and the fixing holes on the two connecting strips are interconnected.

[0011] Furthermore, two limiting rings are fixedly sleeved at intervals on the outer wall of the bottom end of each anchor bar, and the two limiting rings are used to limit and fix the two connecting bars in the vertical direction.

[0012] Furthermore, the bottom surface of the embedded steel plate is provided with several threaded holes, and the top of the anchor bar is provided with a threaded section. The anchor bar is threadedly connected to the embedded steel plate through the threaded section and the threaded holes.

[0013] Furthermore, the bottom surface of the embedded steel plate is provided with a plurality of mounting grooves that correspond one-to-one with the threaded holes and are coaxial. The bottom end of the threaded section of the anchor bar is fixedly sleeved with a connecting ring adapted to the mounting groove, and the connecting ring is inserted into the mounting groove.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] This invention incorporates a connecting component at the bottom of the anchor bars. This component connects several anchor bars distributed in the same row, enabling them to work together under stress. This prevents individual anchor bars from bearing stress independently, effectively reducing stress concentration and the risk of premature failure of local anchor bars, thus improving the overall anchoring effect. Furthermore, by fixing the connecting component to the main reinforcement frame of the foundation and connecting several anchor bars in the same row, the anchor bars can be quickly and accurately positioned and fixed using the foundation's main reinforcement frame. This reduces the difficulty of positioning and fixing the anchor bars during construction, thereby lowering construction difficulty, saving construction time, and reducing time costs.

[0022] The core of this utility model is to provide a pre-embedded steel plate anchoring device for seismic isolation bearings, which can avoid the independent stress of each anchor bar, reduce stress concentration, improve the anchoring effect of the anchoring device, and at the same time, facilitate the positioning and fixing of the anchor bars, reducing time costs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In one specific embodiment of this utility model, such as Figure 1As shown, a seismic isolation bearing pre-embedded steel plate anchoring device includes a pre-embedded steel plate 1, a connecting component 2, and several anchor bars 3. The several anchor bars 3 are arranged in a rectangular array and their top ends are fixedly connected to the pre-embedded steel plate 1. Several connecting components 2 are provided at the bottom ends of the anchor bars 3. The connecting components 2 are fixedly connected to the main steel reinforcement frame of the foundation. The connecting components 2 are used to connect and fix several anchor bars 3 distributed in the same row.

[0026] Anchor bars 3 are anchored by embedding steel plates 1 as the installation foundation for the superstructure support and penetrating deep into the concrete foundation. In traditional devices, the independent stress of each anchor bar can easily lead to stress concentration. However, this device connects the anchor bars 3 in the same row through connecting components 2, enabling them to work together under load. When encountering dynamic loads such as earthquakes, the anchor bars 3 in the same row interact through connecting components 2 to share the load, preventing individual anchor bars 3 from failing due to excessive stress and significantly improving the overall load-bearing capacity of the anchoring device. At the same time, connecting components 2, fixed to the main reinforcement frame of the foundation, can also assist in the rapid and accurate positioning of the anchor bars 3 during construction, reducing construction difficulty.

[0027] In one specific embodiment of this utility model, such as Figures 2-4 As shown, the connecting component 2 includes a connecting plate, which is composed of two connecting strips 201 spliced ​​together. Either of the two connecting strips 201 is fixedly connected to the column reinforcement frame of the foundation. Several semi-circular holes 202, adapted to anchor bars 3, are provided on the opposite sidewalls of both connecting strips 201. Several anchor bars 3 in the same row pass through the semi-circular holes 202 on the two connecting strips 201 one-to-one. Fixing components are provided at both ends of the two connecting strips 201 to fix them together.

[0028] During construction, one connecting strip 201 is first fixed to the foundation column reinforcement frame. Then, the anchor bars 3 in the same row are passed through the semi-circular holes 202 of the two connecting strips 201 in sequence. Next, another connecting strip 201 is spliced ​​onto the connecting strip 201. Finally, the two connecting strips 201 are fixed with the fixing components, so that the connecting plate tightly wraps around the anchor bars 3. The design of the semi-circular holes 202 can tightly fit the anchor bars 3, ensuring connection stability. At the same time, this spliced ​​connecting plate is easy to install, and its position can be flexibly adjusted according to the actual situation on the construction site, quickly completing the positioning and connection of the anchor bars 3.

[0029] Specifically, the fixing component includes two semi-threaded posts 203, which can be spliced ​​together to form a complete threaded post. The two semi-threaded posts 203 are respectively fixedly connected to one side wall of two connecting strips 201. A threaded cylinder 204 is threadedly connected to the threaded post formed by splicing the two semi-threaded posts 203.

[0030] After wrapping the anchor bar 3 with two connecting strips 201, the two semi-threaded columns 203 are spliced ​​together to form a complete threaded column, and then the threaded cylinder 204 is screwed on. By tightening the threaded cylinder 204, the two connecting strips 201 are tightly fitted together, firmly fixing the anchor bars 3 in the same row.

[0031] Specifically, several fixing holes 205 are symmetrically opened through the top surface of the two connecting strips 201, and the fixing holes 205 on the two connecting strips 201 are interconnected.

[0032] By setting the fixing hole 205, the contact area between the connecting strip 201 and the concrete can be increased, the fixing effect between the connecting strip 201 and the concrete can be improved, and the anchoring effect of the anchoring device can be further improved.

[0033] Specifically, two limiting rings 206 are fixedly sleeved at intervals on the outer wall of the bottom end of each anchor bar 3. The two limiting rings 206 are used to limit and fix the two connecting bars 201 in the vertical direction.

[0034] When the two connecting strips 201 wrap around the anchor bar 3, the two limiting rings 206 are located on the upper and lower sides of the two connecting strips 201 respectively, restricting the vertical movement of the connecting strips 201, avoiding affecting the connection effect of the anchor bar 3 and the stability of the overall anchoring device, and also helping to improve the construction accuracy.

[0035] In one specific embodiment of this utility model, such as Figure 2 As shown, the bottom surface of the embedded steel plate 1 has several threaded holes 4, and the top of the anchor bar 3 has a threaded section 5. The anchor bar 3 is threadedly connected to the embedded steel plate 1 through the threaded section 5 and the threaded holes 4.

[0036] The threaded hole 4 and the threaded section 5 on the anchor bar 3 facilitate the quick fixing of the anchor bar 3 onto the embedded steel plate 1, which is convenient for subsequent welding operations.

[0037] Specifically, the bottom surface of the embedded steel plate 1 has several coaxial mounting grooves 6 that correspond one-to-one with the threaded holes 4. The bottom end of the threaded section 5 of the anchor bar 3 is fixedly fitted with a connecting ring 7 that fits the mounting groove 6. The connecting ring 7 is inserted into the mounting groove 6 and welded in place. By welding the connecting ring 7 into the mounting groove 6, the welding area between the embedded steel plate 1 and the anchor bar 3 is increased, thereby improving the connection strength between the anchor bar 3 and the embedded steel plate 1.

[0038] The working principle of this utility model is as follows: When using the pre-embedded steel plate anchoring device for the seismic isolation bearing, before construction, the threaded section 5 at the top of the anchoring bar 3 is threadedly connected to the threaded hole 4 on the bottom surface of the pre-embedded steel plate 1, and the connecting ring 7 is inserted into the installation groove 6, and then welded to complete the fixing of the pre-embedded steel plate 1 and the anchoring bar 3.

[0039] Before pouring concrete, the main steel reinforcement frame of the foundation is first erected. One connecting strip 201 from the connecting component 2 is fixed to the foundation column steel reinforcement frame, so that the anchor bars 3 in the same row pass through the semi-circular holes 202 of the two connecting strips 201 in sequence. Then, the other connecting strip 201 is attached to it, so that the two semi-threaded columns 203 are spliced ​​into a complete threaded column. The threaded cylinder 204 is screwed on and tightened. At this time, the two limiting rings 206 limit the connecting strip 201 in the vertical direction, ensuring that the connecting component 2 firmly connects the anchor bars 3 in the same row and completes the fixation of the anchor bars 3 on the foundation steel reinforcement frame.

[0040] Finally, concrete is poured. Under loads or earthquakes, the anchor bars 3 in the same row work together through the connecting components 2 to jointly bear and transfer the load. The connecting ring 7, the mounting groove 6, and the threaded connection ensure a stable connection between the embedded steel plate 1 and the anchor bars 3, enabling the entire anchoring device to reliably transfer the load of the superstructure to the foundation, thereby effectively ensuring the safety and stability of the engineering structure.
