Description

Technical Field

[0001] This utility model relates to the field of prestressed anchoring technology, and in particular to a high-efficiency and energy-saving prestressed anchoring tool. Background Technology

[0002] In existing construction projects, as the span of steel structures continues to increase, simply using anchor bolts to connect steel columns to foundation short columns is no longer sufficient to meet the shear resistance requirements between the anchor bolts and foundation short columns. Generally, shear keys need to be added. To ensure the positioning and anti-slip properties of the steel structure column bases, anchoring tools are mostly used to constrain and limit the anchor bolts and shear keys. Currently, steel positioning ring plates and wooden shear groove molds are often used, and they are pre-embedded separately.

[0003] Commercially available steel positioning rings are directly fixed to the foundation rebar cage with adhesive, making it difficult to remove them later and hindering their recycling. This results in a waste of steel materials and insufficient practicality of the anchoring tool. Therefore, a high-efficiency and energy-saving prestressed anchoring tool is needed. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This high-efficiency and energy-saving prestressed anchoring tool is equipped with a first threaded column and a first threaded plate. By rotating the first hand handle with external force, the first threaded column can be rotated. Through the threaded connection between the first threaded column and the first threaded plate, the rotation of the first threaded column can cause the first threaded plate to rise and fall. The rise and fall of the first threaded plate can cause the support rod to move. The movement of the support rod can cause the connecting plate to slide through the first slider and the first slide rail, thereby driving the hollow plate to move. The relative movement of the four sets of hollow plates allows the device to be directly installed on the wooden template and then fixed by the threaded groove and threaded bolt. After the glue is injected, the device can be easily disassembled. This avoids the steel positioning ring plate being directly glued to the foundation steel cage, which makes it difficult to remove the steel positioning ring plate later, makes it difficult to achieve the recycling of the positioning ring plate, causes waste of steel materials, and results in insufficient practicality of the anchoring tool.

[0014] 2. This high-efficiency and energy-saving prestressed anchoring tool is equipped with a second threaded post and a second threaded plate. By rotating the second hand handle with external force, the first bevel gear can be driven to rotate. Through the meshing structure of the first and second bevel gears, the rotation of the first bevel gear can cause the second bevel gear to rotate, indirectly driving the second threaded post to rotate. Then, through the threaded connection between the second threaded post and the second threaded plate, the rotation of the second threaded post can cause the second threaded plate to move. The movement of the second threaded plate can cause the scissor frame to extend and retract, thereby driving the slide rail plate to move. The distance between the slide rail plate and the hollow plate can be adjusted. Then, the slide rail plate is fixed by the threaded groove and the threaded bolt, which can fix wooden templates of different heights and increase the stability of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, a high-efficiency and energy-saving prestressed anchoring tool includes a support plate 1. The support plate 1 has a limiting hole 2 inside. An injection hole 3 is provided on one side of the limiting hole 2. A first bearing 4 is provided on the inner side of the support plate 1. A first threaded post 5 is provided on the inner side of the first bearing 4. A first hand-turning handle 6 is fixed to the top of the first threaded post 5. A first threaded plate 7 is threadedly connected to the outer periphery of the first threaded post 5.

[0023] A support rod 9 is provided on one side of the first threaded plate 7. A first rotating shaft 8 is provided at the connection between the first threaded plate 7 and the support rod 9. A connecting plate 11 is provided at the other end of the support rod 9. A second rotating shaft 10 is provided at the connection between the support rod 9 and the connecting plate 11. A first slider 12 is fixed to the side wall of the connecting plate 11. A first slide rail 13 is provided on the outer side of the first slider 12. A hollow plate 14 is fixed to the bottom end of the connecting plate 11. A wooden template 15 is provided on one side of the hollow plate 14. A threaded groove 16 is opened on the side wall of the hollow plate 14. A threaded bolt 17 is provided on the inner side of the threaded groove 16.

[0024] The first threaded post 5 forms a rotating structure with the support plate 1 through the first bearing 4, and the first threaded post 5 forms a fixed structure with the first hand handle 6. The first threaded post 5 is also threadedly connected to the first threaded plate 7. By rotating the first hand handle 6 with external force, the first threaded post 5 can be driven to rotate. Through the threaded connection between the first threaded post 5 and the first threaded plate 7, the rotation of the first threaded post 5 can cause the first threaded plate 7 to rise and fall.

[0025] The first threaded plate 7 forms a rotating structure with the support rod 9 via the first rotating shaft 8, and the support rod 9 forms a rotating structure with the connecting plate 11 via the second rotating shaft 10. The connecting plate 11 forms a sliding structure with the first slide rail 13 via the first slider 12, and the connecting plate 11 forms a fixed structure with the hollow plate 14. The lifting and lowering of the first threaded plate 7 can move the support rod 9, and the movement of the support rod 9 can make the connecting plate 11 slide via the first slider 12 and the first slide rail 13, thereby driving the hollow plate 14 to move. The relative movement of the four sets of hollow plates 14 allows the device to be directly installed on the wooden template 15 and then fixed by the threaded groove 16 and the threaded bolt 17. After the glue is applied, the device can be easily disassembled.

[0026] Example 2

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment further illustrates Example 1. A second bearing 18 is provided on the side wall of the hollow plate 14. A second hand crank 19 is provided on the inner side of the second bearing 18. A first bevel gear 20 is fixed to one end of the second hand crank 19. A second bevel gear 21 is provided on one side of the first bevel gear 20. A connecting post 22 is fixed inside the second bevel gear 21. A second threaded post 23 is fixedly connected to the top of the connecting post 22. A third bearing 24 is provided on the outer periphery of the other end of the second threaded post 23. The outer side of 23 is connected to a second threaded plate 25. A second slider 26 is fixed to the side wall of the second threaded plate 25. A second slide rail 27 is provided on the outer side of the second slider 26. A fixing post 28 is fixed to the other side wall of the second threaded plate 25. A fourth bearing 29 is provided on the outer side of the fixing post 28. A scissor bracket 30 is provided on the outer side of the fourth bearing 29. A fifth bearing 31 is provided on the inner side of the other end of the scissor bracket 30. A cylindrical slider 32 is provided on the inner side of the fifth bearing 31. A slide rail plate 33 is provided on the outer side of the cylindrical slider 32.

[0028] The first bevel gear 20 and the second bevel gear 21 form a meshing structure. The second bevel gear 21 forms a fixed structure with the second threaded post 23 through the connecting post 22. The second threaded post 23 forms a threaded connection with the second threaded plate 25. The second threaded plate 25 forms a sliding structure with the second slide rail 27 through the second slider 26. By rotating the second hand handle 19 by external force, the first bevel gear 20 can be driven to rotate. Through the meshing structure of the first bevel gear 20 and the second bevel gear 21, the rotation of the first bevel gear 20 can cause the second bevel gear 21 to rotate, which indirectly drives the second threaded post 23 to rotate. Then, through the threaded connection of the second threaded post 23 and the second threaded plate 25, the rotation of the second threaded post 23 can cause the second threaded plate 25 to move.

[0029] The second threaded plate 25 and the fixed column 28 form a fixed structure, and the fixed column 28 forms a rotating structure with the scissor frame 30 through the fourth bearing 29. The scissor frame 30 forms a rotating structure with the cylindrical slider 32 through the fifth bearing 31. The cylindrical slider 32 forms a sliding structure with the slide rail plate 33. The movement of the second threaded plate 25 can cause the scissor frame 30 to extend and retract, thereby driving the slide rail plate 33 to move and adjust the distance between the slide rail plate 33 and the hollow plate 14. Then, the slide rail plate 33 is fixed by the threaded groove 16 and the threaded bolt 17, which can fix the wooden template 15 of different heights and increase the stability of the device.

[0030] Working principle: First, the operator needs to rotate the first hand crank 6 by external force, which will drive the first threaded column 5 to rotate. The rotation of the first threaded column 5 will cause the first threaded plate 7 to rise and fall. The rising and falling of the first threaded plate 7 will cause the support rod 9 to move. The movement of the support rod 9 will cause the connecting plate 11 to slide through the first slider 12 and the first slide rail 13, thereby driving the hollow plate 14 to move. The relative movement of the four sets of hollow plates 14 allows the device to be directly installed above the wooden template 15, and then fixed by the threaded groove 16 and the threaded bolt 17. Then, the operator rotates the second hand crank 19 by external force. The first bevel gear 20 can be driven to rotate, which in turn drives the second bevel gear 21 to rotate, indirectly driving the second threaded column 23 to rotate. The rotation of the second threaded column 23 can move the second threaded plate 25, and the movement of the second threaded plate 25 can extend and retract the scissor frame 30, thereby driving the slide rail plate 33 to move. The distance between the slide rail plate 33 and the hollow plate 14 is adjusted, and the slide rail plate 33 is then fixed by the threaded groove 16 and the threaded bolt 17, thus fixing the wooden templates 15 of different heights. After the glue is applied, the device can also be easily disassembled.
