Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of support rods, in particular to an ultra-high performance concrete support rod. Background Art
[0002] In the prior art, the support poles used for tree straightening poles and traffic warning signs are generally made of wooden poles or steel pipes. Wooden poles are easy to rot and have poor durability; steel pipes are prone to corrosion and rust in the open air, and their strength will decrease over time. In addition, steel pipes have recycling value and are easy to lose. Summary of the invention
[0003] The utility model aims to overcome the deficiencies of the prior art and provide an ultra-high performance concrete support rod.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] An ultra-high performance concrete support rod is used as a tree straightening rod and as a supporting pole for traffic warning signs; the support rod comprises a rod body formed by UHPC ultra-high performance concrete, a plurality of steel wires are arranged inside the rod body along its axial direction, and each steel wire is connected to the rod body as a whole.
[0006] As a preferred embodiment, the rod body is a solid structure or a hollow structure.
[0007] As a preferred implementation, the rod body and the steel wire are integrally formed by casting through a mold.
[0008] As a preferred implementation, a screw is pre-embedded and fixed at the top of the rod body.
[0009] As a preferred implementation scheme, an L-shaped slot is provided on the outer wall of the upper end of the rod body, the upper end of the vertical slot of the slot extends to the top of the rod body, and the end of the horizontal slot of the slot is a blind end.
[0010] As a preferred embodiment, the cross section of the outer wall of the rod is circular or polygonal.
[0011] The utility model adopts the above technical solution. The rod body of the support rod is formed by UHPC ultra-high performance concrete and steel wire is arranged inside the rod body, so that the support rod as a whole has high strength, toughness and impact resistance, and has higher durability and corrosion resistance than wooden rods and steel pipes. Therefore, the support rod of the utility model can have better stability when used as a tree straightening rod and as a supporting pole for traffic warning signs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figure 1-2 As shown, the utility model is an ultra-high performance concrete support rod, which is used as a tree straightening rod and a supporting pole for traffic warning signs. The support rod includes a rod body 1 formed of UHPC ultra-high performance concrete, and a plurality of steel wires 2 are arranged inside the rod body 1 along its axial direction, and each steel wire 2 is connected to the rod body 1 as a whole.
[0020] The rod body 1 and the steel wire 2 are integrally formed by casting in a mold, and the manufacturing process is simple.
[0021] According to actual needs, the rod body 1 of the support rod can be a solid structure or a hollow structure. The cross section of the outer wall of the rod body 1 can be circular, polygonal or other special shapes.
[0022] like Figure 3 As shown, when the support rod of the utility model is used as a tree straightening rod, a fixing screw 5 can be pre-buried at the top of the rod body 1 of the support rod. The hole wall of the connecting sleeve 4 on the tree restraint belt 3 has an internal thread that matches the screw 5. When the support rod is sleeved in the connecting sleeve 4, the screw 5 is screwed with the internal thread. This connection method can achieve a fast and stable connection between the support rod and the connecting sleeve 4, and the operation is very convenient. In addition, Figure 4As shown, as another implementation scheme, an L-shaped slot 11 can also be designed on the outer wall of the upper end of the rod body 1 of the support rod. The upper end of the vertical slot of the slot 11 extends to the top of the rod body 1, and the end of the horizontal slot of the slot 11 is a blind end. Correspondingly, a pin 6 is set on the hole wall of the connecting sleeve 4 on the tree tie belt 3. When the upper end of the support rod is inserted into the connecting sleeve 4, the pin 6 is first slid into the vertical slot along the opening at the upper end of the vertical slot of the slot 11. When the support rod is against the top of the connecting sleeve 4, the support rod is rotated to slide the pin 6 into the end of the horizontal slot of the slot 11. This design can also make the connection between the support rod and the connecting sleeve 4 more stable and reliable, and not easy to shake.
[0023] like Figure 5-6 As shown, when the support rod of the utility model is used as a support pole of the traffic warning sign 7, the support rod is a plain rod, and the back locking hoop of the traffic warning sign 7 is fixed on the rod body 1 of the support rod. When used in coastal areas, it can effectively prevent rust and corrosion, and has excellent durability.
[0024] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
