Description

Technical Field

[0001] The utility model relates to a corrosion-resistant cement pole. Background Art

[0002] For segmented cement poles with a length of 8 meters or longer, they are connected by clamps on site before being erected. At the erection site, two cement poles are butt-jointed and connected together by clamps, and then connected and reinforced with bolts. During the assembly process, in order to prevent water from flowing into the gap between the clamp and the cement pole and corroding the cement pole, an installation groove for accommodating a sealing ring is often opened on the clamp. The sealing ring is first placed on the cement pole. When the clamp is connected, the sealing ring is confined in the installation groove. However, the following problems exist during use:

[0003] The processing accuracy of the installation groove is high. If the size deviation of the installation groove occurs, it is difficult for the sealing ring to fit completely on the installation groove. In other words, a gap is likely to appear between the sealing ring and the installation groove, and moisture can still contact the cement pole through the gap, making it difficult to avoid corrosion of the cement pole. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a corrosion-resistant cement pole.

[0005] In order to solve the above-mentioned technical problems, this utility adopts the following technical solutions:

[0006] A corrosion-resistant cement rod comprises a first rod body, a second rod body, a fastener and two symmetrically arranged hoops; a glue injection groove is arranged on the inner side of each hoops, and a glue injection hole and a discharge hole which are connected to the glue injection groove are arranged on the outer surface of the hoops; the two hoops are connected by the fastener to splice the first rod body and the second rod body, and the two glue injection grooves are surrounded to form a space for filling with sealant, and the sealant is injected into the space through the glue injection hole and then solidified to hold the first rod body and the second rod body.

[0007] Preferably, each clamp is provided with a threaded hole, and the fastener is threadably matched with the threaded hole to connect and fix the two clamps.

[0008] Preferably, the glue injection groove is a T-shaped groove.

[0009] Preferably, a guide platform is provided at the upper end of each clamp, and after the clamp is connected and fixed, the guide platform abuts against the surface of the first rod body and the second rod body respectively.

[0010] Preferably, the fastener is a bolt.

[0011] The beneficial effects of the utility model are:

[0012] The corrosion-resistant cement rod of the present application includes a first rod body, a second rod body, a fastener, and two symmetrically arranged clamps; a glue injection groove is arranged on the inner side of each clamp, and a glue injection hole and a discharge hole are arranged on the outer surface of the clamp to connect the first rod body and the second rod body; the two clamps are connected by fasteners to splice the first rod body and the second rod body, and the two glue injection grooves are surrounded to form a space for filling with sealant. The sealant is injected into the space through the glue injection hole and then solidified to hold the first rod body and the second rod body. Compared with the prior art, the present application fills the space surrounded by the two glue injection grooves by injecting sealant into the glue injection hole. Since the sealant is fluid in the initial state, when the sealant is injected into the space, it will fill the gap between the first rod body and the clamp, and the gap between the second rod body and the clamp, and then solidify to form a sealing layer, which effectively prevents water molecules from corroding the cement rod through the gap, and has excellent corrosion resistance; in addition, the staff can also judge whether the sealant fills the above space by observing the state of the sealant in the discharge hole, thereby improving the sealing performance.

The sealant is injected into the space through the glue injection hole 6 and then solidified to hold the first rod body 1 and the second rod body 2.

[0022] Furthermore, each clamp 4 is provided with a threaded hole 40 , and the fastener 3 is threadably matched with the threaded hole 40 to connect and fix the two clamps 4 .

[0023] Furthermore, the glue injection groove 5 is a T-shaped groove.

[0024] Furthermore, a guide platform 41 is provided at the upper end of each clamp 4. After the clamp 4 is connected and fixed, the guide platform 41 abuts against the surface of the first rod body 1 and the second rod body 2 respectively.

[0025] Furthermore, the fastener 3 is a bolt.

[0026] The working principle of the utility model is:

[0027] Before erection, the first rod body 1 and the second rod body 2 are spliced ​​together, and then the two clamps 4 are placed at the splicing positions, and the two clamps 4 are connected and fixed using the fasteners 3; Figure 2As shown, since each clamp 4 is provided with a glue injection groove 5, when the two clamps 4 are connected and fixed, the two glue injection grooves 5 will be connected to form a space for glue injection; then the sealant is injected into the glue injection hole 6, and since the space is connected to the glue injection hole 6, the sealant will enter the glue injection groove 5 through the glue injection hole 6, and at this time the sealant will fill the space surrounded by the two glue injection grooves 5, and when the sealant continues to be injected, when the sealant fills the space, part of the sealant will flow out through the discharge hole 7, and when the sealant is observed to flow out of the discharge hole 7, the glue injection is stopped; then the installed cement pole is left to stand, and after the sealant is cured, the erection work can be carried out.

[0028] In the above technology, the fastener 3 can be implemented by bolts, and then the two clamps 4 can be respectively provided with threaded holes 40 for the bolts to thread and lock.

[0029] In the above technology, the present application also provides a guide platform 41. When the clamp 4 is installed, the guide platform 41 is against the surface of the first rod body 1 and the second rod body 2. Thus, the guide platform 41 has a guiding effect on the water flow, which can prevent part of the water from flowing into the gap between the first rod body 1 and the clamp 4, and the second rod body 2 and the clamp 4.

[0030] Compared with the prior art, the present application injects sealant into the injection hole 6 so that the sealant fills the space enclosed by the two injection grooves 5. Since the sealant is fluid in its initial state, when the sealant is injected into the space, it will fill the gaps between the first rod body 1 and the clamp 4, and between the second rod body 2 and the clamp 4, and then solidify to form a sealing layer, which effectively prevents water molecules from corroding the cement rod through the gaps and has excellent corrosion resistance. In addition, the staff can also judge whether the sealant fills the above-mentioned space by observing the state of the sealant in the discharge hole 7, thereby improving the sealing performance.

[0031] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments of the present invention is only used to explain, not to limit the present invention, but the scope of protection is limited by the content of the claims.
