Description

Technical Field

[0001] The utility model relates to the technical field of anchor rods, in particular to a recyclable threaded anchor rod. Background Art

[0002] In recent years, the number of infrastructure construction projects such as housing construction and roads and bridges in my country has increased, resulting in a large-scale reduction in land resources. In order to achieve efficient use of limited land resources, the current construction engineering field pays more and more attention to the development of underground space, resulting in the continuous increase in the depth of foundation pits in construction projects. Anchor support is widely used in foundation pit support. The existing anchor construction requires secondary grouting, the construction steps are cumbersome, the speed is slow, and the steel strands cannot be recycled, resulting in a certain amount of material waste.

[0003] In order to make the anchor rod recyclable, for example, the Chinese utility model patent with publication number CN213016407U discloses a sleeve-type recyclable anchor rod, including an anchor rod, a sleeve and a tightening nut; the lower end of the sleeve is anchored in a borehole, and the upper end of the sleeve protrudes out of the borehole; the upper end of the sleeve is integrally provided with a plurality of petal clamping pieces, adjacent clamping pieces are arranged at intervals, and a plurality of the clamping pieces are enclosed in a ring, a thread is provided on the outer ring surface of the clamping piece, and a barb-shaped protrusion is provided on the inner ring surface of the clamping piece; the tightening nut is screwed on the outer ring surface of the plurality of the clamping pieces, the lower end of the anchor rod is inserted in the sleeve, an inner clamping rod is further provided between the anchor rod and the sleeve, and the tightening nut is rotated to clamp the anchor rod. The utility model can recycle the support anchor rod, save the mine support cost, and the anchor rod is easy to disassemble.

[0004] However, there are still some problems. Although the inner clamp rod can be placed in the casing, the lower end of the anchor rod is inserted into the casing, and the casing and the anchor rod are fixed to each other by tightening the nut, when disassembling, only the anchor rod needs to be taken out, and the casing remains inside the ground. However, the casing is provided with an inner concave ring and a clamping piece, which undoubtedly increases the production cost. Therefore, a recyclable threaded anchor rod is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a recyclable threaded anchor rod, which has the advantage of being easy to recycle and solves the problem of resource waste.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a recyclable threaded anchor rod, comprising a sleeve, the inner thread of the sleeve is connected to a rod body, the outer surface of the rod body is connected to a fixing bolt, the inside of the rod body is provided with a fixing assembly penetrating to the outside of the rod body, the fixing assembly is used to improve the stability of the rod body, the outer surface of the rod body is covered with a tray, the outer surface of the rod body is connected to two movable bolts respectively located on the upper and lower sides of the tray;

[0007] The fixing assembly includes a connecting plate, a supporting plate, a supporting spring and a supporting assembly. The connecting plate is slidably connected to the rod body and penetrates to the outside of the rod body. The supporting plate is fixed to the inner cavity of the rod body. The supporting plate and the connecting plate are fixed to the supporting spring. The bottom of the connecting plate is fixed to the supporting assembly penetrating the supporting plate.

[0008] By adopting this technical solution, the connecting plate can be moved by rotating the fixing bolt, so that the pushing block pushes the two supporting blocks and the inner wall of the sleeve for support, thereby ensuring the stability of the connection between the sleeve and the rod body, and facilitating subsequent disassembly and recycling, making the overall structure more practical.

[0009] Furthermore, the support assembly includes a pushing block and two supporting blocks, the pushing block is fixed to the connecting plate, the left and right sides of the connecting plate are respectively slidably connected to the two supporting blocks, and the supporting block is slidably connected to the rod body.

[0010] By adopting this technical solution, the push block is used to push the support block to move, so that the support block can contact and support the sleeve, thereby making the whole more stable.

[0011] Furthermore, sliding blocks are fixed on both upper and lower sides of the support block, and a sliding groove slidably connected to the sliding block is provided inside the rod body.

[0012] By adopting this technical solution, the sliding connection between the sliding block and the sliding groove makes the movement of the support block more stable, thereby making the whole less prone to failure and making the whole more practical.

[0013] Furthermore, a push groove is provided on one side opposite to the two sliding blocks, and the push groove is slidably connected to the pushing block.

[0014] By adopting this technical solution, the movement of the pushing block is made more stable through the sliding connection.

[0015] Furthermore, the outer surface of the rod body is slidably connected to two washers, and the two washers are respectively located between the tray and the two movable bolts.

[0016] By adopting this technical solution, the provided gasket can play a buffering role, thereby effectively preventing the movable bolt from excessively squeezing the pallet.

[0017] Furthermore, inclined surfaces are provided inside the pushing groove and on the left and right sides of the pushing block, and the pushing block is a positioning block that is narrow at the bottom and wide at the top.

[0018] By adopting this technical solution, since the pushing block is narrow at the bottom and wide at the top, when the pushing block moves downward, the wide part will push the supporting block to move to both sides.

[0019] Furthermore, sponge pads are fixed on opposite sides of the two support blocks, and the rod body is a threaded rod.

[0020] By adopting this technical solution, the sponge pad is a natural sponge pad, which effectively improves the friction force, thereby making the support more stable.

[0021] Furthermore, a threaded hole matched with the rod body is opened on the top of the sleeve, and the sleeve is a plastic tube.

[0022] By adopting this technical solution, a plastic tube is provided, so that the cost of discarding the sleeve is reduced, and the plastic tube does not affect subsequent work, making the whole more practical.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1 In this embodiment, a recyclable threaded anchor rod comprises a sleeve 1, the internal thread of the sleeve 1 is connected with a rod body 2, and a threaded hole adapted to the rod body 2 is opened on the top of the sleeve 1. The sleeve 1 is a plastic tube, which is set as a plastic tube, so that the cost of discarding the sleeve 1 is reduced, and the plastic tube will not affect the subsequent work, so that the overall work is more practical. The outer surface of the rod body 2 is threadedly connected with a fixing bolt 3, and the fixing bolt 3 is used to push the fixing assembly 4 to move and fix the fixing assembly 4. The interior of the rod body 2 is provided with a fixing assembly 4 that penetrates to the outside of the rod body 2, and the fixing assembly 4 is used to improve the stability of the rod body 2. The outer surface of the rod body 2 is sleeved with a tray 6, and the outer surface of the rod body 2 is threadedly connected with two moving bolts 5 respectively located on the upper and lower sides of the tray 6. The outer surface of the rod body 2 is slidably connected with two gaskets 7, and the two gaskets 7 are respectively located between the tray 6 and the two moving bolts 5. The set gasket 7 can play a buffering role, thereby effectively preventing the moving bolt 5 from excessively squeezing the tray 6.

[0032] In general, the sleeve 1 is fixed and positioned on the ground, and the rod body 2 and the sleeve 1 are threadedly connected to complete the initial fixation of the rod body 2. When disassembling later, the rod body 2 can be disassembled, thereby effectively preventing the waste of resources and making the whole more practical.

[0033] See also Figure 2-3 , in order to facilitate recovery, the fixing assembly 4 in this embodiment includes a connecting plate 401, a supporting plate 402, a supporting spring 403 and a supporting assembly. The connecting plate 401 is slidably connected to the rod body 2 and penetrates to the outside of the rod body 2. The supporting plate 402 is fixed to the inner cavity of the rod body 2. The supporting plate 402 and the connecting plate 401 are fixed with the supporting spring 403. The supporting plate 402 is used to support the supporting spring 403, and the supporting spring 403 can reset the connecting plate 401. The bottom of the connecting plate 401 is fixed to the supporting assembly penetrating the supporting plate 402. The supporting assembly includes a pushing block 404 and two supporting blocks 405. Sliding blocks 406 are fixed on the upper and lower sides of the supporting block 405. A sliding groove slidably connected to the sliding block 406 is provided inside the rod body 2. The sliding connection between the sliding block 406 and the sliding groove makes the movement of the supporting block 405 more stable, thereby making the overall structure less prone to failure and making the overall structure more practical.

[0034] In addition, the pushing block 404 is fixed to the connecting plate 401, and the left and right sides of the connecting plate 401 are respectively slidably connected to the two supporting blocks 405. Sponge pads are fixed on the opposite sides of the two supporting blocks 405. The sponge pads are natural sponge pads, which effectively improve the friction force, thereby making the support more stable. Pushing grooves 407 are provided on the opposite sides of the two sliding blocks 406, and the pushing grooves 407 are slidably connected to the pushing blocks 404. Through the sliding connection, the movement of the pushing block 404 is more stable. Inclined surfaces are provided in the grooves of the pushing grooves 407 and on the left and right sides of the pushing block 404. The pushing block 404 is a positioning block that is narrow at the bottom and wide at the top. Because the pushing block 404 is narrow at the bottom and wide at the top, when the pushing block 404 moves downward, the wide part will push the supporting block 405 to move to both sides. The supporting block 405 is slidably connected to the rod body 2. The pushing block 404 is provided to push the supporting block 405 to move, so that the supporting block 405 can contact and support the sleeve 1, thereby making the overall structure more stable.

[0035] In general, the connecting plate 401 can be moved by rotating the fixing bolt 3, so that the pushing block 404 pushes the two supporting blocks 405 to support the inner wall of the sleeve 1, thereby ensuring the stability of the connection between the sleeve 1 and the rod body 2, and facilitating subsequent disassembly and recycling, making the whole more practical.

[0036] The working principle of the above embodiment is:

[0037] During installation, first use the anchor machine to drill a hole and put the anchor agent into the hole. By rotating the rod body 2, the sleeve 1 and the rod body 2 are threadedly connected for preliminary fixation, and then the connecting plate 401 is pushed to move by rotating the fixing bolt 3, so that the pushing block 404 moves downward. Because the pushing block 404 is narrow at the bottom and wide at the top, the pushing block 404 can push the two support blocks 405 and the inner wall of the sleeve 1 for support, making the whole more stable. Finally, the whole is injected into the borehole through the anchor machine. During subsequent disassembly, the fixing bolt 3 is rotated in the opposite direction, so that the fixing bolt 3 loses support for the connecting plate 401, and then the support block 405 and the sleeve 1 lose support. Finally, the rod body 2 can be taken out by rotating the rod body 2. The overall structure is simple, and resources are effectively saved, making the overall structure more practical.
