Description

Technical Field

[0001] The invention relates to the technical field of cement poles, and in particular to a durable structure based on self-healing concrete. Background Art

[0002] As is known, cement poles are mainly composed of steel bars and concrete, so they are also called reinforced concrete cement poles, which are mainly used as cable support pillars in industries such as electricity, communications, railways, and petroleum. Some cement poles installed on both sides of the road may collide with vehicles when a traffic accident occurs, resulting in damage to the cement poles and reduced durability.

[0003] At present, a known anti-collision cement pole (CN219672291U) includes a cement pole body, the outer surface of which is fixedly connected to two mounting plates, the lower surface of one mounting plate and the upper surface of the other mounting plate are provided with an annular groove, the inner sliding connection of the annular groove is provided with an anti-collision component, and one side of the anti-collision component is fixedly connected with a buffer component. The anti-collision cement pole, through the provision of the anti-collision component and the buffer component, when the cement pole body is hit, the impact force pushes the anti-collision component to rotate, and the anti-collision roller also rotates to reduce the impact force. During the rotation, the buffer component can reduce the force exerted on the anti-collision component. When used in combination, the cement pole body is well protected, the possibility of it being damaged is greatly reduced, and its normal use is guaranteed to a large extent.

[0004] Another known anti-collision cement pole (CN211057689U) includes: a cement pole, a buffer material layer, a main shaft, a supporting telescopic rod, a slide groove, a bearing tube, a connecting rod, and a spring; the outer side of the cement pole is sleeved with a buffer material layer, the main shaft is rotatably installed on the outer side of the buffer material layer, the supporting telescopic rod is fixedly installed on the outer side of the main shaft, the slide groove is embedded and installed inside the main shaft, the bearing tube is fixedly installed on the top of the supporting telescopic rod, one end of the connecting rod is fixedly installed on the right side of the bearing tube, and the other end is slidably installed inside the slide groove, and the spring is fixedly installed on the slide groove. The buffer material layer can effectively protect the cement pole from damage by external forces, and the main shaft, the supporting telescopic rod, the bearing tube and the spring can effectively avoid the single-point force problem of the cement pole when it is subjected to external forces.

[0005] In actual applications, car collisions may cause direct damage to the anti-collision components and buffer material layers in the above-mentioned anti-collision cement poles. Under greater impact, it may even affect the normal use of related components (i.e., the buffer components of CN219672291U, the main shaft, supporting telescopic rods, bearing tubes and springs in CN211057689U). There is a problem that they cannot be quickly replaced or partially replaced. If you want to continue using them, you need to at least replace the entire set of damaged parts with new ones. Disassembly is cumbersome, time-consuming, labor-intensive and costly. Summary of the invention

[0045] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0046] In the related art, the anti-collision cement poles, such as CN219672291U and CN211057689U, can provide a certain degree of protection for the cement poles by providing an anti-collision component and a buffer component or a buffer material layer, thereby reducing the possibility of damage. However, the existing anti-collision cement poles often need to be replaced with a new set of anti-collision components and a buffer component or a buffer material layer after a collision, and the disassembly is cumbersome, time-consuming and labor-intensive.

[0047] In view of this, the embodiments of the present invention application aim to provide a durable structure based on self-healing concrete. By arranging a self-healing buffer part, it can provide buffering protection for the cement poles in the event of a collision. By arranging a locking component, the self-healing anti-collision component can be quickly replaced, thereby avoiding the need for overall replacement, effectively saving costs, and solving the above-mentioned problems.

[0048] According to the following Figure 1-Figure 6 A durable structure based on self-healing concrete of the present invention is described in detail.

[0049] Please refer to Figure 1 , 5 6. A durable structure based on self-healing concrete is provided in an embodiment of the present invention, comprising a cement pole 10, a split connecting sleeve 20 and a self-healing buffer 30; wherein the split connecting sleeve 20 is configured to be detachably mounted on the outer surface of the cement pole 10; the self-healing buffer 30 is configured to be at least arranged on the side of the split connecting sleeve 20 facing the road surface; the self-healing buffer 30 is provided with a locking member 34, and the locking member 34 is configured to realize quick replacement and disassembly of the self-healing buffer 30.

[0050] In some implementations of the embodiments of the present invention, reference Figure 1 and Figure 2 The split connecting sleeve 20 includes a first connecting sleeve 21 and a second connecting sleeve 22 symmetrically arranged on both sides of the outside of the cement pole 10. The two butt ends of the first connecting sleeve 21 and the second connecting sleeve 22 are detachably fixedly connected by a fastening member 23; a resisting member 24 is provided at the butt end, and the resisting member 24 is used to achieve pre-fixation between the first connecting sleeve 21 and the second connecting sleeve 22; a self-healing buffer 30 is arranged on the second connecting sleeve 22; a pressing member 25 is provided between the first connecting sleeve 21 and the cement pole 10, and the pressing member 25 is used to achieve pre-fixation between the first connecting sleeve 21 and the cement pole 10.

[0051] The design of the pressing member 25 and the resisting member 24 can realize the pre-fixation of the first connecting sleeve 21 and the second connecting sleeve 22, thereby facilitating the locking of the fastening member 23 and improving the convenience of operation.

[0052] In some implementations of the embodiments of the present invention, reference Figure 2 The fastening member 23 includes a screw rod 231 fixedly connected to the second connecting sleeve 22 . The screw rod 231 penetrates the first connecting sleeve 21 and is locked by a nut 232 .

[0053] In a specific implementation, four screw rods 231 are fixedly connected to the second connecting sleeve 22 , and two screw rods 231 are respectively disposed at each butt end thereof. Each screw rod 231 penetrates the first connecting sleeve 21 and is threadedly connected to a nut 232 .

[0054] In some implementations of the embodiments of the present invention, reference Figure 1 The pressing member 25 includes a connecting block 251, a first connecting column 252, a first spring 253 and a pressing plate 254; the connecting block 251 is fixedly connected to the first connecting sleeve 21, the first connecting column 252 is slidably connected to the connecting block 251, the first spring 253 is sleeved on the outside of the first connecting column 252, the pressing plate 254 is fixedly connected to one end of the first connecting column 252, one side of the pressing plate 254 is in contact with the cement pole 10, one end of the first spring 253 is in contact with the pressing plate 254, and the other end of the first spring 253 is in contact with the connecting block 251. More specifically, the cross section of one end of the first connecting column 252 can be a T-shaped structure.

[0055] In some implementations of the embodiments of the present invention, reference Figure 2 The blocking member 24 includes a second connection column 241, a stopper 242 and a second spring 243. The second connection column 241 is fixedly connected to the butt end of the second connection sleeve 22. The stopper 242 is slidably connected to the second connection column 241. The stopper 242 and the first connection sleeve 21 are in contact with each other. The second spring 243 is sleeved on the outside of the second connection column 241. One end of the second spring 243 is in contact with the second connection column 241, and the other end of the second spring 243 is in contact with the stopper 242. More specifically, the cross section of the end of the stopper 242 is a trapezoidal structure.

[0056] When in use, first take the first connecting sleeve 21 and the second connecting sleeve 22 to the outside of the cement pole 10, and then move the first connecting sleeve 21 and the second connecting sleeve 22 to make them close to each other. During this process, the screw 231 will be inserted into the interior of the first connecting sleeve 21, thereby achieving the positioning between the first connecting sleeve 21 and the second connecting sleeve 22.

[0057] Since the cross-section of the end of the stopper 242 is a trapezoidal structure, as the first connecting sleeve 21 moves, it will resist the stopper 242 from sliding on the second connecting column 241, and the second spring 243 will contract. As the first connecting sleeve 21 continues to move, the second spring 243 will extend and drive the stopper 242 to move toward the first connecting sleeve 21 and resist the first connecting sleeve 21. At this time, the first connecting sleeve 21 and the second connecting sleeve 22 will be unable to detach.

[0058] At this time, the support plate 254 will be pressed tightly against the cement pole 10 under the action of the first spring 253. Since there is friction between the support plate 254 and the cement pole 10, after the first connecting sleeve 21 and the second connecting sleeve 22 are loosened, the first connecting sleeve 21 and the second connecting sleeve 22 will not fall off the cement pole 10 under the action of friction.

[0059] This enables the first connecting sleeve 21 and the second connecting sleeve 22 to be pre-fixed, avoiding the need to drag the first connecting sleeve 21 and the second connecting sleeve 22 by hand when tightening the nut 232, thereby effectively improving the convenience of operation. Subsequently, multiple nuts 232 can be tightened to achieve final fixation of the first connecting sleeve 21 and the second connecting sleeve 22.

[0060] In some implementations of the embodiments of the present invention, reference Figure 3 and Figure 5 The self-healing buffer 30 includes a self-healing anti-collision component 31 and two buffer components 32. The upper end of the self-healing anti-collision component 31 is connected to the first part of the second connecting sleeve 22 through a limiting component 33 and a first buffer component 32 in sequence. The lower end of the self-healing anti-collision component 31 is connected to the second part of the second connecting sleeve 22 through a second buffer component 32. The second part is located axially below the first part.

[0061] In some implementations of the embodiments of the present invention, reference Figure 2 A plurality of connection sleeves 221 are fixedly provided on the second connection sleeve 22 , and each connection sleeve 221 is connected to a corresponding self-healing buffer 30 ; the self-healing buffer 30 is engaged and connected with the corresponding connection sleeve 221 through the connection seat 313 .

[0062] By setting the limiting member 33, the buffer member 32 and the connecting sleeve 221 can be quickly connected, so that the first connecting sleeve 21, the second connecting sleeve 22 and the buffer member 32 can be installed step by step. The step-by-step installation method can save more physical effort.

[0063] In some implementations of the embodiments of the present invention, reference Figure 3The self-healing anti-collision component 31 is mainly composed of a support plate 311 and a self-healing concrete anti-collision block 312, and each buffer component 32 is mainly composed of a third connecting column 321, a third spring 322, a slider 323, a connecting rod 324 and a connecting block 325; more specifically, the cross-section of the end of the support plate 311 is an L-shaped structure, and the two connecting rods 324 are symmetrically distributed about the middle of the support plate 311.

[0064] The two third connecting columns 321 are respectively fixedly connected to the two ends of the connecting seat 313, the third spring 322 is sleeved on the outside of the third connecting column 321, and the slider 323 is slidably connected to the third connecting column 321; one end of the connecting rod 324 is rotatably connected to the slider 323, and the other end thereof is rotatably connected to the connecting block 325, and the connecting block 325 is fixedly connected to the support plate 311; the self-healing concrete anti-collision block 312 is snap-connected to the side of the support plate 311 facing the road surface; the locking member 34 is detachably connected to the top between the support plate 311 and the self-healing concrete anti-collision block 312.

[0065] Self-healing concrete refers to experimental concrete that can repair cracks by itself. It contains a permeable crystallization active masterbatch that generates calcium carbonate through chemical reaction and complex reaction. It is activated by the infiltration of corrosive rainwater acting on the structure, so as to partially fill the cracked part of the concrete. This new material may increase the service life of concrete and effectively reduce the maintenance cost of concrete structures. Therefore, the self-healing concrete material is used to make the self-healing concrete anti-collision block 312. When the damage is small, it can automatically repair itself over time, thereby extending the service life.

[0066] During use, when a traffic accident occurs, the car will first come into contact with the self-healing concrete anti-collision block 312, and then under the action of the impact force, the slider 323 will slide on the third connecting column 321, and the third spring 322 will contract. The contraction of the third spring 322 can play a buffering role, thereby effectively reducing the impact force on the cement pole 10, reducing the damage to the cement pole 10, and effectively improving the durability of the cement pole 10.

[0067] In some implementations of the embodiments of the present invention, reference Figure 4The locking member 34 includes a first locking block 341, a connecting plate 342, two fourth connecting columns 343, two guide blocks 344, a connecting piece 345 and two fourth springs 346; the first locking block 341 is slidably connected to the top of the supporting plate 311, the bottom end of the first locking block 341 is engaged with the top of the self-healing concrete anti-collision block 312, the connecting plate 342 is fixedly connected to the top of the first locking block 341, the two fourth connecting columns 343 are fixedly connected to the bottom end of the connecting plate 342, the two guide blocks 344 are fixedly connected to the supporting plate 311, the two guide blocks 344 are slidably connected to the two fourth connecting columns 343 in a one-to-one correspondence, the two fourth springs 346 are each sleeved on a fourth connecting column 343, the connecting piece 345 is fixedly connected to the bottom ends of the two fourth connecting columns 343, one end of the two fourth springs 346 abuts against the connecting piece 345, and the other end abuts against the corresponding guide block 344. More specifically, the cross-section of the bottom end of the first clamping block 341 is a trapezoidal structure, and the first clamping block 341 and the connecting plate 342 are vertically arranged.

[0068] When a collision occurs, the self-healing concrete anti-collision block 312 will come into contact with the car, so it is easy to be damaged. When the damage is minor, it can be automatically repaired over time based on its own properties. When the damage is major, it needs to be replaced. In this way, by replacing the self-healing concrete anti-collision block 312 separately, the need for overall replacement can be avoided, thereby effectively saving costs.

[0069] More specifically, when replacing the self-healing concrete anti-collision block 312, by pushing the connecting piece 345, the connecting piece 345 drives the two fourth connecting columns 343 to move, and the guide block 344 can guide the fourth connecting column 343. The movement of the two fourth connecting columns 343 will drive the connecting plate 342 to move, and the movement of the connecting plate 342 will drive the first clamping block 341 to move away from the top of the self-healing concrete anti-collision block 312; when the first clamping block 341 and the top of the self-healing concrete anti-collision block 312 are not engaged, the self-healing concrete anti-collision block 312 can be removed from the support plate 311, thereby realizing the rapid disassembly of the anti-collision block, and then the new self-healing concrete anti-collision block 312 can be engaged on the support plate 311; when the self-healing concrete anti-collision block 312 is fully engaged with the support plate 311, the fourth spring 346 will extend to engage the first clamping block 341 with the top of the anti-collision block, and at this time, the replacement of the new self-healing concrete anti-collision block 312 is realized.

[0070] In some implementations of the embodiments of the present invention, reference Figure 6The limiting member 33 is arranged on the buffer member 32, and the limiting member 33 includes a slide bar 331, a second clamping block 332, and a fifth spring 333; the slide bar 331 is slidably connected to the connecting seat 313, the second clamping block 332 is fixedly connected to the slide bar 331, and the top of the second clamping block 332 is engaged with the corresponding connecting sleeve 221; the fifth spring 333 is arranged inside the connecting seat 313, one end of the fifth spring 333 abuts against the slide bar 331, and the other end of the fifth spring 333 abuts against the connecting seat 313. More specifically, the cross section of the slide bar 331 is an L-shaped structure, and the cross section of the top of the second clamping block 332 is a trapezoidal structure.

[0071] When the first connecting sleeve 21 and the second connecting sleeve 22 are fixed, the connecting seat 313 can be moved, and the end of the connecting seat 313 is engaged with the corresponding connecting sleeve 221; when the end of the connecting seat 313 is fully engaged with the corresponding connecting sleeve 221, the fifth spring 333 will extend to drive the slide bar 331 to move, and the movement of the slide bar 331 will drive the second clamping block 332 to move toward the connecting seat 313 and engage with the connecting seat 313, and the connecting seat 313 cannot be separated from the inside of the connecting sleeve 221, thereby realizing the rapid installation of the connecting seat 313. Next, repeat the above operation to make all the connecting sleeves 221 engage with the connecting seat 313, so that step-by-step installation can be achieved, avoiding the need to spend a lot of effort to lift the device during one-time installation, thereby effectively improving the convenience of operation.

[0072] The durable structure based on self-healing concrete provided by the embodiment of the present invention has at least the following significant advantages in practical application:

[0073] 1) The durability structure of the embodiment of the present invention requires that the first connecting sleeve 21 and the second connecting sleeve 22 be installed on the outside of the cement pole before use, specifically by moving the first connecting sleeve 21 and the second connecting sleeve 22 closer to each other and using the screw 231 for pre-positioning. Then, the resisting member 24 is used to ensure that the first connecting sleeve 21 and the second connecting sleeve 22 cannot be separated, and the pressing member 25 is used to achieve tight contact between the first connecting sleeve 21 and the second connecting sleeve 22, so that the first connecting sleeve 21 and the second connecting sleeve 22 will not fall off the cement pole after the first connecting sleeve 21 and the second connecting sleeve 22 are loosened. Therefore, the effective pre-fixation of the first connecting sleeve 21 and the second connecting sleeve 22 is finally achieved, so that the final locking and fixing of the first connecting sleeve 21 and the second connecting sleeve 22 can be achieved through multiple nuts 232.

[0074] 2) The durable structure of the embodiment of the present invention can use the limiting member 33 to quickly fix the buffer member 32 on the connecting sleeve 221 after locking the first connecting sleeve 21 and the second connecting sleeve 22. The step-by-step installation can effectively save physical effort, thereby improving the convenience of operation.

[0075] 3) The durability structure of the embodiment of the present invention can reduce the damage to the cement pole by using the buffer component 32 when the car hits the cement pole, thereby effectively improving the durability of use.

[0076] 4) The durability structure of the embodiment of the present invention is that the self-healing concrete anti-collision block 312 where the buffer component 32 contacts the car is easily damaged during a collision. When the self-healing concrete anti-collision block 312 is damaged, it can be quickly disassembled through the locking component 34, thereby avoiding the need for overall replacement, thereby improving the durability of use.

[0077] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any simple modifications and equivalent changes made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the present invention.
