Description
Technical Field
[0001] The invention relates to the technical field of concrete poles, in particular to an impact-resistant ultra-high performance concrete pole. Background Art
[0002] Concrete poles are mainly used in power grid and communication construction. They have the advantages of long service life, non-corrosion, and high quality consistency. At present, in order to improve the strength of concrete poles, the main way is to optimize the structural design of the poles, such as increasing the wall thickness of the poles, using high-strength concrete materials, and designing a reasonable cross-sectional shape, so as to improve the impact resistance of the poles.
[0003] Traditional concrete poles use a structure of cast concrete with a steel frame. Although the surface of this type of concrete pole is hard and not easily damaged, once a bump occurs, a gap will appear on the surface of the concrete pole, and the internal stress inside the concrete pole will become unstable, causing the concrete pole to become fragile from the gap. Therefore, a concrete pole that can solve this problem is needed. Summary of the invention
[0004] In order to solve the above technical problems, the present invention proposes an impact-resistant ultra-high performance concrete pole, which can be divided into an outer layer and an inner layer through a layered design. The outer layer has a certain buffering effect. Therefore, when it is impacted, the inner layer is less affected. Therefore, it can be ensured to the greatest extent that the concrete pole will not be affected in normal use after being impacted.

[0006] Preferably, the protection component further includes limiting steel bars, a plurality of the limiting steel bars are fixedly connected to the base, a plurality of the hard rubbers are respectively sleeved on the plurality of limiting steel bars, and the cross-sections of the plurality of hard rubbers are in an "I" shape.
[0007] Preferably, the protection assembly further includes a first limit block, a plurality of the first limit blocks are fixedly connected to the base, and a plurality of special-shaped steels are respectively located between the plurality of first limit blocks and the pole body.
[0008] Preferably, the auxiliary component further includes a second limit block, a plurality of the second limit blocks are fixedly connected to the top cover, and a plurality of special-shaped steels are respectively located between the plurality of second limit blocks and the pole body.
[0009] Preferably, the auxiliary component also includes a limiting steel bar and a slot, three of the limiting steel bars are fixedly connected to the inside of the groove, the three limiting steel bars are distributed in a circular array, and the three limiting steel bars fit the inner wall of the pole body, six slots are opened on the top cover and the base, and the ends of the three limiting steel bars are respectively located inside the six slots.
[0010] Preferably, the detection assembly includes a first sensor, a first spring and a first spherical shell, the first sensor is fixedly connected to the inside of the groove, one end of the first spring is fixedly connected to the first sensor, and the other end of the first spring is fixedly connected to the first spherical shell.
[0011] Preferably, the detection assembly also includes a second sensor, a second spring and a second spherical shell, the second sensor is fixedly connected to the top cover, one end of the second spring is fixedly connected to the second sensor, and the other end of the second spring is fixedly connected to the second spherical shell.
[0012] Preferably, the first spherical shell and the second spherical shell are both located between the three limiting steel bars, and the first spherical shell and the second spherical shell are both connected to the three limiting steel bars, and the diameter of the first spherical shell is greater than the diameter of the second spherical shell.
[0013] Compared with the prior art, the present invention has the following significant advantages:
[0014] First, in the present invention, when the concrete pole is impacted, the impacted position will be on the outside, that is, on the concrete protective layer. Since the concrete protective layer is cast on the special-shaped steel, and there is hard rubber between the special-shaped steels, the impacted concrete protective layer will undergo slight deformation together with the special-shaped steel and squeeze the adjacent hard rubber. At this time, it is equivalent to forming a buffer for the impact, so that the concrete protective layer itself is not easily damaged by the impact.
[0015] Second: In the present invention, after the concrete protective layer is impacted, the deformation capacity of the hard rubber is limited, that is, the buffering effect is limited. Therefore, after a part of the impact force is buffered, it will still be able to pass through the concrete protective layer and the special-shaped steel and be applied to the pole body. However, since the contact area between the special-shaped steel and the pole body is large, the pressure per unit area is small when the impact force is transmitted to the pole body. Therefore, the pole body is not easy to be damaged, and at this time the pole body itself is needed to resist the impact, while the steel skeleton and spiral steel bars in the pole body increase the strength of the pole body.
[0016] Third: Since the pole body is wrapped by the external concrete protective layer, the entire concrete pole is divided into an outer layer and an inner layer, of which the pole body is the inner layer. When the impact force received by the concrete protective layer is partially buffered and then transmitted to the pole body, the damage of the pole body cannot be observed with the naked eye. At this time, the first spherical shell and the second spherical shell can be used to determine whether the pole body is damaged. Since the force received by the concrete protective layer will be transmitted to the pole body through the special-shaped steel, and the contact surface between the special-shaped steel and the pole body is large, when the pole body is impacted, the force area is large and the pressure is small. In this case, the pole body cannot resist the impact even if it cannot produce a gap, but it is more likely to break directly, but this requires a huge impact to achieve.
[0017] Fourthly: if the pole body is subjected to a strong impact and cannot resist it, the structure of the pole body itself will be destroyed, thereby compressing the three limit steel bars. At this time, the three limit steel bars will be deformed and compress the first spherical shell and the second spherical shell. With the deformation of the three limit steel bars, the positions of the first spherical shell and the second spherical shell will change, and the lengths of the first spring and the second spring will also change. Since the first spring and the second spring are respectively connected to the first sensor and the second sensor, when the lengths of the two change, the tension indications on the first sensor and the second sensor will change. Therefore, it is only necessary to connect the first sensor and the second sensor to the external equipment to read the indications on the first sensor and the second sensor. By observing the changes in the indications of the first sensor and the second sensor, it can be judged whether the pole body is broken. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0028] The present invention provides an impact-resistant ultra-high performance concrete pole through improvement. The technical solution of the present invention is:
[0029] like Figure 1-Figure 6As shown, an impact-resistant ultra-high performance concrete pole comprises a pole body 1, a plurality of steel skeletons 2 are arranged inside the pole body 1, and a spiral steel bar 3 is arranged inside the pole body 1, a protective component 4 is arranged on the outside and bottom of the pole body 1, and the protective component 4 comprises a base 41, a groove 42, a special-shaped steel 43, a concrete protective layer 44 and a hard rubber 46, the base 41 is arranged at the bottom of the pole body 1, the groove 42 is opened on the base 41, the pole body 1 is installed inside the groove 42, a plurality of special-shaped steels 43 are fixedly connected to the outside of the pole body 1, and a plurality of concrete protective layers 44 are respectively arranged inside the plurality of special-shaped steels 43, a plurality of hard rubbers 46 are arranged on the outside of the pole body 1, and the plurality of hard rubbers 46 and the plurality of special-shaped steels 43 are staggered, an auxiliary component 5 is arranged on the top and inside of the pole body 1, the auxiliary component 5 comprises a top cover 51, the top cover 51 is arranged on the top of the pole body 1, and a detection component 6 is arranged on the top cover 51 and the base 41.
[0030] The concrete pole is divided into an outer layer and an inner layer. The inner layer is the pole body 1, which has a simple structure, and the outer layer is composed of a concrete protective layer 44, a special-shaped steel 43 and other structures. The outer layer can protect the inner layer, and by utilizing the slight deformation characteristic of the hard rubber 46, when the concrete protective layer 44 is impacted, it can also cushion part of the impact force by squeezing the hard rubber 46.
[0031] Furthermore, the protective component 4 also includes limiting steel bars 45, and multiple limiting steel bars 45 are fixedly connected to the base 41. Multiple hard rubbers 46 are respectively mounted on the multiple limiting steel bars 45. The cross-sections of the multiple hard rubbers 46 are in the shape of an "I". The limiting steel bars 45 can be prefabricated and welded in advance, or temporarily welded. When the limiting steel bars 45 are fixed, the hard rubber 46 can be inserted into the limiting steel bars 45. The shape of the hard rubber 46 fits the edge shape of the special-shaped steel 43. Therefore, the "I" shape of the hard rubber 46 can play a role similar to a barb, thereby clamping the special-shaped steel 43.
[0032] Furthermore, the protection assembly 4 also includes a first limit block 47 , a plurality of first limit blocks 47 are fixedly connected to the base 41 , and a plurality of special-shaped steels 43 are respectively located between the plurality of first limit blocks 47 and the pole body 1 .
[0033] Furthermore, the auxiliary component 5 also includes a second limit block 52, and multiple second limit blocks 52 are fixedly connected to the top cover 51. Multiple special-shaped steels 43 are respectively located between the multiple second limit blocks 52 and the pole body 1. The first limit block 47 and the second limit block 52 can be inserted into the edge notch of the special-shaped steel 43, but the size of the first limit block 47 and the second limit block 52 is slightly smaller than the edge size of the special-shaped steel 43. Therefore, after the first limit block 47 and the second limit block 52 clamp the special-shaped steel 43, if the special-shaped steel 43 and the concrete protective layer 44 thereon are impacted, the special-shaped steel 43 can shake within a smaller range and squeeze the hard rubber 46, thereby completing the force buffering.
[0034] Furthermore, the auxiliary component 5 also includes a limiting steel bar 53 and a slot 54. The three limiting steel bars 53 are fixedly connected to the inside of the groove 42. The three limiting steel bars 53 are distributed in a circular array, and the three limiting steel bars 53 fit the inner wall of the pole body 1. Six slots 54 are opened on the top cover 51 and the base 41. The ends of the three limiting steel bars 53 are respectively located inside the six slots 54. The limiting steel bars 53 are arranged at an angle so that they can fit the inner wall of the pole body 1 after installation.
[0035] Furthermore, the detection component 6 includes a first sensor 61, a first spring 62 and a first spherical shell 63. The first sensor 61 is fixedly connected to the inside of the groove 42, one end of the first spring 62 is fixedly connected to the first sensor 61, and the other end of the first spring 62 is fixedly connected to the first spherical shell 63.
[0036] Furthermore, the detection assembly 6 also includes a second sensor 64 , a second spring 65 and a second spherical shell 66 . The second sensor 64 is fixedly connected to the top cover 51 , one end of the second spring 65 is fixedly connected to the second sensor 64 , and the other end of the second spring 65 is fixedly connected to the second spherical shell 66 .
[0037] Furthermore, the first spherical shell 63 and the second spherical shell 66 are both located between the three limiting steel bars 53, and the first spherical shell 63 and the second spherical shell 66 are both connected to the three limiting steel bars 53. The diameter of the first spherical shell 63 is larger than the diameter of the second spherical shell 66. The special-shaped steel 43 will transmit the external force to the pole body 1, but the contact area between the special-shaped steel 43 and the pole body 1 is large, so the pressure is small. Therefore, when the pole body 1 is subjected to the external force from the special-shaped steel 43, it is not easy to be damaged or notched. However, once the impact is too strong, the pole body 1 will break directly. At this time, the three limiting steel bars 53 and the first spherical shell 63 and the second spherical shell 66 will be compressed, and the first sensor 61 and the second sensor 64 will show changes in the indications. Therefore, by observing the changes in the indications, it can be known whether the pole body 1 inside the concrete pole is damaged.
[0038] The specific working method is: first, prefabricate the base 41 and the top cover 51 in advance, and then when installing the concrete pole, insert the pole body 1 into the groove 42, and then install two of the three limiting steel bars 53, so that the two limiting steel bars 53 are inserted into the three slots 54 on the base 41 in turn. At this time, the two limiting steel bars 53 will fit the inner wall of the pole body 1, and then install multiple special-shaped steels 43 on the surface of the pole body 1. Each first limiting block 47 can clamp a special-shaped steel 43, so that multiple special-shaped steels 43 can be distributed in a circular array, and then insert limiting steel bars 45 and hard rubber 46 between the gaps of multiple special-shaped steels 43. The limiting steel bars 45 can also be welded in advance, and only the hard rubber 46 needs to be inserted into the limiting steel bars 45. Then, place the top cover 51 on the top of the pole body 1, and reserve a certain space to place the most The last limiting steel bar 53 is installed. Since the first spherical shell 63 and the second spherical shell 66 are both clamped in the three limiting steel bars 53, it is necessary to first place the top cover 51 above the pole body 1, and then put the second spherical shell 66 into the pole body 1, and then leave space to install the third limiting steel bar 53, so that the third limiting steel bar 53 can push the second spherical shell 66 between the three limiting steel bars 53. When the first spherical shell 63 and the second spherical shell 66 are successfully placed between the three limiting steel bars 53, the top cover 51 can be buckled on the pole body 1, and the second limiting block 52 on the top cover 51 can be used to relatively fix the top cover 51 and multiple special-shaped steels 43. At this time, the entire concrete pole is poured on the outside to fill each special-shaped steel 43 with concrete, thereby forming a concrete protective layer 44. After the concrete protective layer 44 solidifies, the entire concrete pole is installed.
[0039] When the concrete pole is impacted, the impacted position will be on the outside, that is, on the concrete protective layer 44. Since the concrete protective layer 44 is cast on the special-shaped steel 43, and there is hard rubber 46 between the special-shaped steel 43, the impacted concrete protective layer 44 will undergo slight deformation together with the special-shaped steel 43 and squeeze the adjacent hard rubber 46. At this time, it is equivalent to forming a buffer for the impact, so that the concrete protective layer 44 itself is not easily damaged by the impact.
[0040] After the concrete protective layer 44 is impacted, the deformation capacity of the hard rubber 46 is limited, that is, the buffering effect is limited. Therefore, after a part of the impact force is buffered, it will still be able to pass through the concrete protective layer 44 and the special-shaped steel 43 and be applied to the pole body 1. However, since the contact surface between the special-shaped steel 43 and the pole body 1 is large, the pressure per unit area is small when the impact force is transmitted to the pole body 1. Therefore, the pole body 1 is not easy to be damaged, and at this time, the pole body 1 itself is needed to resist the impact, while the steel skeleton 2 and spiral steel bars 3 in the pole body 1 increase the strength of the pole body 1.
[0041] Since the pole body 1 is wrapped by the external concrete protective layer 44, the entire concrete pole is divided into an outer layer and an inner layer, wherein the pole body 1 is the inner layer. When the impact force received by the concrete protective layer 44 is partially buffered and then transmitted to the pole body 1, the damage of the pole body 1 cannot be observed with the naked eye. At this time, whether the pole body 1 is damaged can be judged by the first spherical shell 63 and the second spherical shell 66. Since the force received by the concrete protective layer 44 will be transmitted to the pole body 1 through the special-shaped steel 43, and the contact surface between the special-shaped steel 43 and the pole body 1 is large, when the pole body 1 is impacted, the force-bearing area is large and the pressure is small. In this case, even if the pole body 1 cannot resist the impact, no gap will be generated, but it is more likely to break directly, but this requires a huge impact to achieve.
[0042] If the pole body 1 is subjected to a strong impact and cannot resist it, the structure of the pole body 1 itself will be destroyed, thereby compressing the three limiting steel bars 53. At this time, the three limiting steel bars 53 will be deformed and compress the first spherical shell 63 and the second spherical shell 66. As the three limiting steel bars 53 are deformed, the positions of the first spherical shell 63 and the second spherical shell 66 will change. After the positions of the first spherical shell 63 and the second spherical shell 66 change, the lengths of the first spring 62 and the second spring 65 will also change. Since the first spring 62 and the second spring 65 are respectively connected to the first sensor 61 and the second sensor 64, when the lengths of the two change, the tension indications on the first sensor 61 and the second sensor 64 will change. Therefore, it is only necessary to connect the first sensor 61 and the second sensor 64 to the external equipment to read the indications on the first sensor 61 and the second sensor 64. By observing the changes in the indications of the first sensor 61 and the second sensor 64, it can be judged whether the pole body 1 is broken, etc., so it can play an early warning role.

Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
