Description

Technical Field

[0001] This utility model relates to the field of anchor bolts, and in particular to a high corrosion-resistant prestressed anchor bolt that can be installed quickly. Background Technology

[0002] Prestressed anchors apply tension to the structure before it is subjected to external loads, putting the structure under compression. This prestress can offset some or all of the tensile stress generated by the external loads, thereby reducing structural deformation and cracking. When the structure is subjected to external loads, the prestressed anchors work together with the structure to improve overall stability and safety.

[0003] In the prior art, such as the prestressed anchor bolt structure described in Chinese Announcement No. CN216304702U, which relates to the technical field of prestressed anchor bolt assemblies for wind turbine generator sets, a prestressed anchor bolt structure includes a lower anchor plate, an upper anchor plate, an anchor bolt, and a fixing component. The lower anchor plate has multiple first fixing holes, and the upper anchor plate has multiple second fixing holes corresponding to the lower anchor plate. One end of the anchor bolt is fixedly connected to the fixing component, and the other end of the anchor bolt passes through the first and second fixing holes sequentially. The anchor bolt is fixed to the surface of the lower anchor plate through the fixing component. By utilizing the fixed connection between the end of the anchor bolt and the fixing component, the installation efficiency of the wind turbine foundation anchor bolt assembly is effectively improved, and the quality control of anchor bolt installation is more favorable. This effectively improves the tensioning qualification rate of the anchor bolt assembly after the wind turbine generator set is installed and during operation, reduces anchor bolt damage caused by tensioning tests, and alleviates the technical problems of anchor bolt damage and substandard prestressing quality in the prior art during the tensioning process.

[0004] The aforementioned application achieves the effect of reducing anchor bolt damage caused by tension tests through multiple components. However, the anchor bolts of this device are in direct contact with concrete. When cracks appear in the concrete, the anchor bolts may be corroded and damaged, which reduces the overall convenience and timeliness to some extent. Utility Model Content

[0005] This invention provides protection for the device by setting a protective coating and placing the anchor rod inside the sleeve, thereby diffusing pressure onto the surface of the base plate and improving the service life of the device, thus solving the problems mentioned in the background art.

When using this device, the sleeve is inserted through the base plate into a suitable position within the concrete, and the mounting plate is pressed against the interior of the concrete by rotating the nut and tightening the pressure block, facilitating stable installation of the device in a suitable working environment.

[0007] Preferably, the surface of the sleeve is fixedly connected with several locking strips at equal intervals. The size of the locking strips matches the size of the sleeve. When using this device, the design of the size and distribution of the locking strips improves the stability of the sleeve when it is installed inside the concrete.

[0008] Preferably, the surface of the mounting plate has a plurality of openings evenly distributed, and the surface of the mounting plate is provided with anti-slip texture. When using the device, the openings on the surface of the mounting plate and the anti-slip texture design facilitate the mounting plate to expand outward and press against the inner wall of the concrete.

[0009] Preferably, the outer surfaces of the mounting post and the threaded post are provided with a protective coating. The protective coating is made of hot-dip galvanized coating. When using the device, the protective coating on the surfaces of the mounting post and the threaded post provides protection for the device.

[0010] Preferably, washers are fixedly connected to both the front and rear ends of the mounting sleeve, and several reinforcing plates are fixedly connected at equal intervals to the side of the mounting sleeve. When using the device, the structural strength of the device is improved by the structure of washers and reinforcing plates connected to the surface of the mounting sleeve.

[0011] Preferably, the pressure block is shaped like a frustum, and the size of the washer on the side of the mounting sleeve near the base plate is larger than the size of the washer on the side of the mounting sleeve near the nut. When using this device, the pressure is diffused and distributed on the surface of the base plate through the design of the size and position of the two washers.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the inner wall of the mounting plate is squeezed by the frustum-shaped pressure block. The mounting plate is easy to expand under the action of the opening. The anti-slip texture on the surface of the mounting plate presses against the inner wall of the concrete, which makes it easy for the device to be stably installed in a suitable working site. Furthermore, the protective coating on the surface of the mounting column and the threaded column provides a protective effect for the device.

[0013] 2. In this utility model, the structural strength of the device is improved by the design of the reinforcing plate structure and distribution position of the mounting sleeve surface connection. The pressure is diffused and distributed on the surface of the base plate by the design of the size and position of the two gaskets, which improves the service life of the device.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a high corrosion-resistant prestressed anchor bolt that can be quickly installed, including a base plate 1, a sleeve 2 fixedly connected to the rear side of the base plate 1, an installation plate 4 fixedly connected to the rear side of the sleeve 2, an installation post 6 slidably installed inside the sleeve 2, a threaded post 7 fixedly connected to one end of the installation post 6, a pressure block 9 fixedly connected to the other end of the installation post 6, a nut 10 threadedly fitted to the outer side of the threaded post 7, and an installation sleeve 11 fitted on the outer side of the threaded post 7. When using the device, the sleeve 2 is inserted through the base plate 1 into a suitable position in the concrete, and the installation plate 4 is pressed against the interior of the concrete by rotating the nut 10 and tightening the pressure block 9, so that the device can be stably installed in a suitable working site.

[0019] like Figure 1 As shown, several locking strips 3 are fixedly connected around the surface of the sleeve 2 at equal intervals. The size of the locking strips 3 matches the size of the sleeve 2. When using this device, the design of the size and distribution of the locking strips 3 improves the stability of the sleeve 2 when it is installed inside the concrete.

[0020] like Figure 2 As shown, the surface of the mounting plate 4 has several openings 5 ​​evenly distributed, and the surface of the mounting plate 4 is provided with anti-slip texture. When using the device, the openings 5 ​​on the surface of the mounting plate 4 and the anti-slip texture design make it easy for the mounting plate 4 to expand outward and press against the inner wall of the concrete.

[0021] like Figure 3 As shown, both the outer surface of the mounting column 6 and the outer surface of the threaded column 7 are provided with a protective coating 8. The material of the protective coating 8 is hot-dip galvanized coating. When using the device, the protective coating 8 provided on the surfaces of the mounting column 6 and the threaded column 7 provides protection for the device.

[0022] like Figure 3 As shown, washers 12 are fixedly connected to both the front and rear ends of the mounting sleeve 11, and several reinforcing plates 13 are fixedly connected at equal intervals on the side of the mounting sleeve 11. When using the device, the structural strength of the device is improved by the structure of washers 12 and reinforcing plates 13 connected to the surface of the mounting sleeve 11.

[0023] like Figure 1 As shown, the pressure block 9 is shaped like a frustum. The size of the washer 12 on the side of the mounting sleeve 11 near the base plate 1 is larger than the size of the washer 12 on the side of the mounting sleeve 11 near the nut 10. When using this device, the pressure is diffused and distributed on the surface of the base plate 1 through the size and positional design of the two washers 12.

[0024] The usage method and working principle of this device are as follows: First, insert the sleeve 2 into a suitable concrete hole. The base plate 1 is attached to the surface of the concrete. The retaining strip 3 on the surface of the sleeve 2 reduces the possibility of the sleeve 2 rotating. Rotate the nut 10 to pull the threaded column 7 outward. At this time, the frustum-shaped pressure block 9 squeezes the inner wall of the mounting plate 4. The mounting plate 4 is easy to expand under the action of the opening 5. The anti-slip texture on the surface of the mounting plate 4 presses against the inner wall of the concrete, which makes it easy for the device to be stably installed in a suitable working place. The protective coating 8 on the surface of the mounting column 6 and the threaded column 7 provides a protective effect for the device. Secondly, the structural strength of the device is improved by the design of the reinforcing plate 13 connected to the surface of the mounting sleeve 11 and the distribution of the two gaskets 12 in terms of size and position. The pressure is diffused and distributed on the surface of the base plate 1, which improves the service life of the device.
