DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; of course, it can also be a mechanical connection or an electrical connection; in addition, it can also be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0044] Example:

[0045] The specific embodiments of the present invention are as follows Figure 1-6 As shown, a modularly assembled transmission line tower structure includes a tower body and a concrete base 5, wherein the tower body is fixedly mounted on the concrete base 5 and connected by concrete pouring. The tower body includes a plurality of tower body units arranged in sequence from top to bottom. Each tower body unit includes a vertically arranged core tube module 1 and a plurality of main rod modules 2 arranged vertically around the axis of the core tube module 1. The core tube module 1 and the main rod module 2 in the tower body unit, as well as adjacent main rod modules 2, are connected by connecting angle steels 3. At the same time, in order to realize the connection between tower body units, adjacent tower body units are coaxially and detachably connected by connecting flanges 4 arranged at the ends of the core tube module 1 and the ends of the main rod module 2.

[0046] In this embodiment, in order to further improve the connection strength between the core tube module 1 and the main rod module 2, and between adjacent main rod modules 2: adjacent main rod modules 2 in the same tower body unit are detachably connected by a set of cross-arranged connecting angle steels 3, and the cross-arranged connecting angle steels 3 are reinforced and fixed by bolts at the intersection. As a result, two triangles with an integrated structure are formed between adjacent main rod modules 2 through the connecting angle steels 3, which have a high connection strength. At the same time, the main rod module 2 and the core tube module 1 in the same tower body unit are detachably connected by two connecting angle steels 3, and the two connecting angle steels 3 and the main rod module 2 form a triangle, so the main rod module 2 and the core tube module 1 also have a high connection strength.

[0047] Before the construction of the transmission line tower, the core tube module 1, the main rod module 2 and the connecting angle steel 3 are first manufactured in the factory, and then the modular design components are transported to the construction site. When constructing the transmission line tower, the core tube module 1, the main rod module 2 and the connecting angle steel 3 are first spliced ​​together to form a number of tower units; then the bottom tower unit is connected to the concrete base 5 and poured with concrete; finally, through simple lifting equipment, such as a pulley block, multiple tower units are stacked in sequence and fixed with bolts to complete the construction of the tower.

[0048] In the transmission line tower, since the tower body is composed of a core tube structure located at the axial position of the tower body and a plurality of main poles arranged around the core tube axis, and the core tube and the main poles are connected as a whole through the connecting angle steel 3. Therefore, compared with the existing transmission tower, the tower body composed of the core tube and the main poles has significantly improved overall stability, lateral stiffness and stable bearing capacity, and can effectively overcome the damage to the tower structure caused by earthquakes and wind-induced vibrations.

[0049] At the same time, since the core tube module 1, the main rod module 2 and the connecting angle steel 3 are first spliced ​​together to form a tower unit during construction, it also avoids the situation where construction workers assemble tower units at high altitude, thereby shortening the construction period and making the assembly more precise.

[0050] In addition, since the main structure of the tower can be disassembled into a modular core tube module 1 and a main rod module 2, and both the core tube module 1 and the main rod module 2 are standard parts pre-processed in the factory. Compared with a complete transmission line tower, modularly designed parts have the advantages of small size and light weight, and are easy to handle and transport. Therefore, even in remote areas in the wild where large-scale modern construction facilities cannot be effectively used, the modular parts can be easily transported to the construction site. In addition, the lighter, pre-processed modular parts also enable construction workers to complete the tower assembly construction without large-scale modern construction facilities, only through hoisting and high-strength bolt connections, thereby reducing the impact of the environment on the construction progress and quality, and improving construction efficiency.

[0051] In the transmission line tower, the connection angle steel 3 is connected with the core tube module 1 and the main rod module 2, as shown in FIG. Figure 2 , 3 As shown in Figures 4 and 5, ear plates 32 are welded on the side walls of the core tube module 1 and the main rod module 2, and the ends of the connecting angle steels 3 are detachably connected to the ear plates 32 through a plurality of angle steel connecting bolts 31. This design realizes full bolt assembly on site, reduces the demand for welding equipment, and can also conveniently splice and combine the core tube module 1, the main rod module 2 and the connecting angle steel 3 together to form a tower unit, thereby improving construction efficiency.

[0052] In this embodiment, the ear plate 32 is provided with an elliptical ear plate bolt hole 321 for the angle steel connection bolt 31 to pass through. Angle steel connection energy consuming plates 33 are also provided in parallel on both side plate surfaces of the ear plate 32, and the ear plate 32 and the angle steel connection energy consuming plates 33 are positioned and connected by positioning pins 34. The angle steel connection bolt 31 passes through the ear plate bolt hole 321 and the two angle steel connection energy consuming plates 33, and the connecting angle steel 3 is also provided with a positioning pin 34 that passes through the connecting angle steel 3, the ear plate 32 and the two angle steel connection energy consuming plates 33. The presence of the positioning pin 34 can facilitate the positioning and assembly between the connecting angle steel 3, the angle steel connection bolt 31, the ear plate 32 and the angle steel connection energy consuming plates 33.

[0053] At the same time, if Figure 5 , 6 As shown, the two connected connecting flanges 4 are detachably connected by a plurality of flange connecting bolts 41 arranged around the axis of the connecting flanges 4, and a flange connecting energy absorbing plate 42 is also provided between the two connected connecting flanges 4. The flange connecting bolts 41 pass through the two connecting flanges 4 and the flange connecting energy absorbing plate 42 from top to bottom. In addition, in order to strengthen the connection strength between the connecting flange 4 and the side wall of the core tube module 1, and between the connecting flange 4 and the side wall of the main rod module 2, a plurality of flange reinforcing ribs 43 arranged around the axis of the connecting flange 4 are provided between the connecting flange 4 and the side wall of the core tube module 1, and between the connecting flange 4 and the side wall of the main rod module 2.

[0054] When affected by earthquakes and wind-induced vibrations, the angle steel connection energy absorbing plates 33 and the flange connection energy absorbing plates 42 arranged at each connection node can be used to reduce vibration and dissipate energy, thereby effectively improving the overall stability and rigidity of the tower body.

[0055] As for the specific structure of the concrete base 5, Figure 8 As shown, the concrete base 5 includes an assembled skeleton and a concrete shell. Among them, the assembled skeleton includes a central base module 51 connected to the lower end of the lowest core tube module 1 at the top, and a plurality of edge base modules 52 are arranged around the central base module 51 and connected to the lower end of the lowest main rod module 2 in a one-to-one correspondence. The central base module 51 is connected to the lowest core tube module 1, and the edge base module 52 is connected to the lowest main rod module 2, which can provide multiple connection support points for the tower body, thereby improving the overall stability and lateral stiffness of the tower body. At the same time, the central base module 51 and the edge base module 52 are connected by a crossbeam connection module 53, which can connect multiple connection support points into one, further improving the overall stability and lateral stiffness of the tower body.

[0056] Moreover, the modular design of the assembled frame can significantly reduce the weight of a single block, making it easy to carry and put into place, and is particularly suitable for use in construction sites with poor terrain. At the same time, the central base module 51, the edge base module 52, and the crossbeam connection module 53 can all be prefabricated in the factory, and the production quality can be guaranteed. Compared with on-site casting, the prefabricated modules can speed up the construction efficiency.

[0057] Regarding the specific structure of the central basic module 51, Fig. 9 and 10 As shown, the central basic module 51 includes a plurality of central module vertical steel bars 512 and a plurality of central module transverse steel bars 513. The plurality of central module vertical steel bars 512 and the plurality of central module transverse steel bars 513 are bound and connected by a plurality of central module stirrups 514 and a central module concrete protective layer 515 is poured on the outside. The upper end of the central module vertical steel bar 512 extends outside the central module concrete protective layer 515.

[0058] Regarding the specific structure of the edge basic module 52, Fig.11 and 12 As shown, the edge basic module 52 includes a plurality of edge module vertical steel bars 522 and a plurality of edge module transverse steel bars 523. The plurality of edge module vertical steel bars 522 and the plurality of edge module transverse steel bars 523 are bound and connected by a plurality of edge module stirrups 524 and an edge module concrete protective layer 525 is poured on the outside. The upper end of the edge module vertical steel bar 522 extends outside the edge module concrete protective layer 525.

[0059] In this embodiment, in order to realize the connection between the central basic module 51, the edge basic module 52 and the beam connection module 53. Fig. 9 , 11 As shown in Figures 1 and 13, the central basic module 51 is provided with a central module I-shaped steel 511 whose main body is pre-embedded in the central module concrete protective layer 515 on the connection surface with the cross beam connection module 53. The edge basic module 52 is provided with an edge module I-shaped steel 521 whose main body is pre-embedded in the edge module concrete protective layer 525 on the connection surface with the cross beam connection module 53. Correspondingly, the cross beam connection module 531 includes an axially extending connection module H-shaped steel 531. And the cross beam connection module 531 also includes a connection module concrete protective layer 535 cast outside the connection module H-shaped steel 531. The two ends of the connection module H-shaped steel 531 are respectively positioned and clamped with the central module I-shaped steel 511 and the edge module I-shaped steel 521 through the H-shaped steel clamping groove 532 set on the end surface thereof.

[0060] Furthermore, in order to strengthen the connection between the central base module 51, the edge base module 52 and the crossbeam connection module 53, as shown in FIG. Fig.14 , 15As shown, the connection module H-shaped steel 531 and the center module I-shaped steel 511, as well as the connection module H-shaped steel 531 and the edge module I-shaped steel 521 are fastened together by a plurality of vertical tension bolts 534 vertically penetrating the entire crossbeam connection module 531 and a plurality of transverse tension bolts 533 transversely penetrating the entire crossbeam connection module 531.

[0061] Each basic module is pre-buried with steel, which makes the durability, wind resistance and earthquake resistance of the assembled frame relatively good. At the same time, each basic module is connected by "positioning clamping + bolt fastening", which is convenient for disassembly and assembly while also making the formed structure have good integrity.

[0062] In this embodiment, Figure 1 and 7 As shown, the transmission line tower also includes a plurality of wind ropes 6 vertically arranged around the axis of the tower body, the upper end of the wind ropes 6 is bound and connected to the top of the tower body, and the lower end is bound and connected to the steel ingot 63. The steel ingot 63 is vertically provided with a plurality of anchor bolts 64 for fixing it to the bottom surface. By providing the wind ropes 6, the overall stability and lateral stiffness of the transmission line tower can be further improved.

[0063] In addition, regarding the specific structure of the wind rope 6, the wind rope 6 includes at least two coaxially arranged steel cables 61, and the adjacent steel cables 61 are connected by a tensioning mechanism 62.

By rotating the annular component 621, the two screw rods 622 can be relatively moved, thereby tightening the two steel cables 61, thereby achieving the purpose of tightening the wind rope 6.
