The bolt is characterized in that a blind hole is formed in the end face of the transverse portion of the bolt body, internal threads are processed on the inner wall of the blind hole, a sacrificial anode metal rod is arranged in the blind hole, external threads are processed on the outer wall of the sacrificial anode metal rod, the sacrificial anode metal rod is in threaded connection with the blind hole, and one end of the sacrificial anode metal rod extends out of the opening of the blind hole. The bolt assembly is not easy to corrode and has long service life.
Description
Technical Field
The utility model relates to a bolt, what specifically says so is used for linking to each other bottom the equipment with the ground rag bolt subassembly that has anticorrosive function, the specially adapted coastal area.
Background
Rag bolt subassembly is about to the mechanism that equipment and ground link to each other, and the wide use is to outdoor equipment such as transformer cabinet, street lamp on. Traditional rag bolt subassembly, including steel bolt body, this bolt body is L shape, and its upper portion processing has the external screw thread, and the upper portion of bolt body is connected with gland nut. In coastal areas, due to the influence of the ocean, a large amount of salt particles are mixed in soil. When traditional rag bolt subassembly was used in coastal region, because the influence of salt class granule in the soil, it is very fast to be corroded, and life is shorter.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model provides an rag bolt subassembly with anticorrosive function, use this bolt subassembly difficult quilt corruption, life is longer.
In order to solve the problems, the following technical scheme is provided:
the utility model discloses an rag bolt subassembly with anticorrosive function includes steel bolt body, and this bolt body is L shape, and its upper portion processing has the external screw thread, and the upper portion of bolt body is connected with gland nut. The bolt is characterized in that a blind hole is formed in the end face of the transverse portion of the bolt body, internal threads are processed on the inner wall of the blind hole, a sacrificial anode metal rod is arranged in the blind hole, external threads are processed on the outer wall of the sacrificial anode metal rod, the sacrificial anode metal rod is in threaded connection with the blind hole, and one end of the sacrificial anode metal rod extends out of the opening of the blind hole.
The bolt body is provided with a protective cylinder, the outer diameter of the protective cylinder is larger than that of the compression nut, a supporting sheet is arranged on the bolt body below the compression nut corresponding to the protective cylinder, the supporting sheet and the bolt body are in sliding fit, an annular slot is formed in the periphery of the supporting sheet corresponding to the lower end of the protective cylinder, and the lower end of the protective cylinder is inserted into the annular slot in a use state.
And a polyethylene anticorrosive layer is arranged on the outer wall of the protective cylinder.
By adopting the scheme, the method has the following advantages:
because the utility model discloses a be provided with the blind hole on the bolt body horizontal part terminal surface of rag bolt subassembly with anticorrosive function, processing has the internal thread on the inner wall of this blind hole, there is sacrificial anode metal stick in the blind hole, processing has the external screw thread on sacrificial anode metal stick's the outer wall, is threaded connection between sacrificial anode metal stick and blind hole, and the one end of sacrificial anode metal stick stretches out outside from the oral area of blind hole. When in use, the lower end of the bolt body and the sacrificial anode metal bar are buried into the foundation; then, sleeving a base of the equipment to be fixed on the bolt body through the mounting hole; and then, screwing the compression nut. The sacrificial anode metal rod is adopted, so that the corrosion speed of the bolt body can be greatly reduced, and the service life of the whole foundation bolt assembly is greatly prolonged.
Drawings
Figure 1 is the structural schematic of the anchor bolt assembly of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the anchor bolt assembly with anticorrosion function of the present invention includes a steel bolt body 4, the bolt body 4 is L-shaped, an external thread is processed on the upper portion of the bolt body 4, and the upper portion of the bolt body 4 is connected with a compression nut 6. Be provided with blind hole 8 on the 4 horizontal parts terminal surfaces of bolt body, processing has the internal thread on the inner wall of this blind hole 8, there is sacrificial anode metal rod 7 in the blind hole 8, processing has the external screw thread on the outer wall of sacrificial anode metal rod 7, is threaded connection between sacrificial anode metal rod 7 and blind hole 8, and the one end of sacrificial anode metal rod 7 stretches out outside from the oral area of blind hole 8.
The top of bolt body 4 is covered with a protection section of thick bamboo 3, and the external diameter of a protection section of thick bamboo 3 is greater than gland nut 6's external diameter, has backing sheet 1 on the bolt body 4 of gland nut 6 below that a protection section of thick bamboo 3 corresponds, is the sliding fit between backing sheet 1 and bolt body 4, and the backing sheet 1 that the lower extreme of a protection section of thick bamboo 3 corresponds has annular slot 2 all around, and under the user state, 3 lower extremes of a protection section of thick bamboo insert in annular slot 2.
And a polyethylene anticorrosive layer 5 is arranged on the outer wall of the protective cylinder 3.
When in use, the lower end of the bolt body 4 and the sacrificial anode metal bar 7 are embedded into the foundation 9. Then, the device base 10 to be fixed is fitted on the bolt body 4 through the mounting hole. Then, the support sheet 1 is put on, and the support sheet 1 is made to abut against the apparatus base 10. However, the compression nut 6 is screwed on. And finally, covering the protection cylinder 3, and inserting the lower end of the protection cylinder 3 into the annular slot 2. By adopting the sacrificial anode metal bar 7, the corrosion speed of the bolt body 4 can be greatly reduced, so that the service life of the whole foundation bolt assembly is greatly prolonged. Utilize the cooperation of a protection section of thick bamboo 3 and backing sheet 1, can protect the bolt body 4 of 9 tops of ground to prevent that the rainwater from corroding bolt body 4, further prolonged whole rag bolt subassembly life.
