Description

Technical Field

[0001] This utility model relates to the field of steel structure tower technology, and more specifically, to a steel structure tower diagonal bracing connection structure. Background Technology

[0002] In various large-scale engineering projects, such as towering power transmission towers, communication base stations, and giant wind turbine towers, steel structure towers have become an indispensable and important support structure due to their advantages of high strength, light weight, and convenient construction. However, during the installation of steel structure towers, the length and fitting angle of the connection between the support block and the main body of the steel structure tower in the traditional inclined groove connection structure are often determined in the design stage, lacking adjustability during actual installation. The actual conditions on the construction site are complex, and manufacturing errors of the tower body and minor deviations during the installation process may lead to the support block and the tower body not being able to match precisely. This mismatch not only increases the installation difficulty but also causes uneven stress on the connection part, resulting in an unstable overall connection and posing serious safety hazards. In the event of extreme working conditions, it is very likely to cause local damage or even the entire tower to collapse. Therefore, we propose a steel structure tower inclined bracing connection structure to solve the above problems. Utility Model Content

[0003] The main purpose of this utility model is to provide a steel structure tower inclined brace connection structure, which solves the problem that in the process of installing steel structure towers, the length and fitting angle of the connection between the support block and the main body of the steel structure tower are often determined in the design stage, and lack adjustability in actual installation. However, the actual situation on the construction site is complex, and manufacturing errors of the tower body and slight deviations in the installation process may lead to the support block and the tower body not being able to match precisely. This mismatch not only increases the installation difficulty, but also makes the stress on the connection part uneven, resulting in an unstable overall connection and creating serious safety hazards. In the event of extreme working conditions, it is very likely to cause local damage or even the entire tower to collapse.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A steel tower diagonal bracing connection structure includes several fixed blocks that overlap front to back. Each fixed block has a support block movably installed at its upper and lower ends. An extension mechanism is installed between the fixed block and the support block. A locking groove is provided through the middle of the interior of each fixed block. Limiting rods are installed through the overlapping locking grooves. A groove is provided inside the support block at the end away from the fixed block. A connecting frame is movably installed inside the groove. Auxiliary holes are provided through the two ends of the connecting frame.

[0006] Preferably, the extension mechanism includes extension rods, which are fixedly installed on the upper and lower sides of the fixed block, and the support block has extension holes on the side near the fixed block, with the extension rods respectively engaging inside the extension holes.

[0007] Preferably, extension tubes are fixedly installed on the upper and lower sides of the fixing block, and extension grooves are provided on the side of the support block near the fixing block, with the extension tubes respectively engaging and installed inside the extension grooves.

[0008] Preferably, the interior of the extension tube is provided with a plurality of first threaded holes, and the front and rear ends of the interior of the extension groove are provided with a plurality of second threaded holes, and the first threaded holes and the second threaded holes that overlap each other are connected by a first bolt through a thread.

[0009] Preferably, a fixing rod is fixedly installed in the middle of the inside of the groove, and the rod body of the fixing rod is movably installed inside the connecting frame.

[0010] Preferably, the interior of the connecting frame is provided with a plurality of first guide holes arranged in a circular array around the fixed rod, and the interior of the groove is provided with second guide holes at the front and rear ends, respectively, with the first guide holes and the second guide holes overlapping each other.

[0011] Preferably, a second bolt is installed through the first and second guide holes that overlap each other, and a nut is threadedly installed on the outer side of the rod of the second bolt near the fixed block, and the nut is in contact with the support block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) In this utility model, the two fixed blocks can be rotated by using the limiting rod as the axis, so that the operator can conveniently adjust the angle of the two support blocks according to the actual force analysis and site conditions, ensuring that the angle of the support can always cope with various external forces at the best angle. Then, through the extension mechanism, the length between the support block and the fixed block, as well as the fitting angle between the connecting frame and the tower body, can be flexibly adjusted, thereby achieving a perfect match with the tower body. This all-round adjustable design effectively solves the shortcomings of the traditional connection structure, greatly improves the stability of the connection, and significantly enhances the safety performance of the steel structure tower.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 9As shown in the figure, this utility model embodiment proposes a steel structure tower diagonal bracing connection structure, including several fixed blocks 1, which overlap front and back. Support blocks 2 are movably installed at the upper and lower ends of each fixed block 1. Extension mechanisms 3 are installed between the fixed blocks 1 and the support blocks 2. A locking groove 7 is provided through the middle of the interior of the fixed block 1. Limiting rods 8 are installed through the overlapping locking grooves 7. A groove 4 is provided inside the support block 2 at the end away from the fixed block 1. A connecting frame 5 is movably installed inside the groove 4. Auxiliary holes 6 are provided through the two ends of the connecting frame 5.

[0026] like Figures 4 to 9 As shown, in another embodiment of this utility model, the extension mechanism 3 includes an extension rod 304, which is fixedly installed on the upper and lower sides of the fixing block 1. The support block 2 has extension holes 302 on the side near the fixing block 1, and the extension rods 304 are respectively engaged inside the extension holes 302. Extension tubes 303 are fixedly installed on the upper and lower sides of the fixing block 1. The support block 2 has extension grooves 301 on the side near the fixing block 1, and the extension tubes 303 are respectively engaged inside the extension grooves 301. A plurality of first threaded holes 305 are respectively passed through the interior of the extension tubes 303. A plurality of second threaded holes 306 are respectively passed through the front and rear ends of the extension grooves 301. The overlapping first threaded holes 305 and second threaded holes... A first bolt 307 is threadedly installed between 306. A fixing rod 308 is fixedly installed in the middle of the inside of the groove 4. The rod body of the fixing rod 308 is movably installed inside the connecting frame 5. A number of first guide holes 309 are arranged in a circular array around the fixing rod 308. A second guide hole 310 is provided at the front and rear ends of the inside of the groove 4. The first guide hole 309 and the second guide hole 310 overlap each other. A second bolt 311 is movably installed between the overlapping first guide hole 309 and the second guide hole 310. A nut 312 is threadedly installed on the outer side of the rod body of the second bolt 311 near the fixing block 1. The nut 312 fits against the support block 2.

[0027] When installation is required, the user can directly control the rotation of the fixing block 1 via the limit rod 8, thereby allowing the fixing block 1 to drive the support block 2 to adjust the angle of the diagonal bracing. Simultaneously, the user can also directly pull the support block 2, extending it along the extension tube 303 and extension rod 304 to both sides, allowing the support block 2 to be adjusted according to the spacing between the tower bodies. After adjustment, the user can thread the first bolt 307 into the overlapping first threaded hole 305 and second threaded hole 306 to complete the positioning of the support block 2, extension tube 303, and fixing block 1, ensuring stability. The user can then control the connecting frame 5 to fix the rod 3... The 08 axis rotates to adjust the connection frame 5 according to the slight angle changes between the tower body and the support block 2, so that the connection frame 5 can fit more flatly with the tower body and there will be no gaps between the connection frame 5 and the tower body due to angular deviation. After the adjustment is completed, the user can insert the second bolt 311 into the overlapping first guide hole 309 and second guide hole 310 to stabilize the connection frame 5 and the support block 2 and make them a whole. Then, the second bolt 311 and the support block 2 are integrated by the nut 312 to make the whole more stable. Finally, the user can connect the connection frame 5 and the tower body through the auxiliary hole 6 and the connecting bolt to complete the installation of the diagonal brace structure.

[0028] The working principle of this type of steel tower diagonal bracing connection structure:

[0029] In use, the user can first control the rotation of the fixing block 1 directly through the limit rod 8, thereby allowing the fixing block 1 to drive the support block 2 to adjust the angle of the diagonal bracing. Simultaneously, the user can also directly pull the support block 2, allowing it to extend and adjust along the extension tube 303 and extension rod 304 to both sides, thus allowing the support block 2 to be adjusted according to the spacing between the tower bodies. After adjustment, the user can then thread the first bolt 307 into the overlapping first threaded hole 305 and second threaded hole 306 to complete the positioning of the support block 2, extension tube 303, and fixing block 1, ensuring stability. The user can then control the connecting frame 5 to use the fixing rod 308 as... The axis rotates to adjust according to the slight angle changes between the tower body and the support block 2, allowing the connecting frame 5 to fit more evenly against the tower body, preventing angular deviations that could cause gaps between the connecting frame 5 and the tower body. After adjustment, the user can insert the second bolt 311 into the overlapping first guide hole 309 and second guide hole 310 to secure the connecting frame 5 and the support block 2, making them a single unit. Then, the second bolt 311 and the support block 2 are further secured with the nut 312, making the whole structure more stable. Finally, the user can connect the connecting frame 5 and the tower body through the auxiliary hole 6 and the connecting bolt to complete the installation of the diagonal brace structure.
