[0039] Example

[0040] like Figure 1 , Figure 2 and Figure 4 As shown, a lattice steel-concrete bridge tower structure proposed by the present invention includes multiple groups of main skeletons 1 arranged longitudinally, and the main skeleton 1 includes four groups of longitudinal steel pipes 11. Two groups of transverse steel pipes 12 are connected between two adjacent groups of longitudinal steel pipes 11. The longitudinal steel pipes 11 are connected to the transverse steel pipes 12, so that when pouring concrete into the longitudinal steel pipes 11, concrete is poured into the transverse steel pipes 12 simultaneously. The main skeleton 1 also includes obliquely arranged inclined steel pipes 14, and both ends of the oblique steel pipes 14 are fixedly connected with connecting plates 13. The connecting plates 13 are installed at the connection between the longitudinal steel pipes 11 and the transverse steel pipes 12. The oblique steel pipes 14 are fixedly connected to the longitudinal steel pipes 11 and the transverse steel pipes 12 through the connecting plates 13 to form a lattice-type steel structure as a whole, thereby enhancing the bending and shear resistance of the structure. The oblique steel pipes 14 are used to provide a force transmission path to enhance the force performance at the node. Concrete is poured inside the longitudinal steel pipe 11, the transverse steel pipe 12 and the oblique steel pipe 14. The steel structure provides strength and rigidity, and the concrete provides compression resistance and durability. The main frame 1 is connected by welding. After welding, the internal concrete is poured. The prefabricated sections are transported to the site for installation to ensure structural stability and construction safety. By splitting the bridge tower into multiple longitudinal segments and constructing in sections, it is beneficial to improve construction efficiency and facilitate on-site installation.

[0041] Furthermore, multiple groups of studs 111 are welded to the outer wall of the longitudinal steel pipe 11, and multiple groups of studs 111 at the same height are distributed in a circular array to enhance the interface bonding force. Multiple groups of first stiffening ribs 112 arranged at equal intervals are fixedly connected to the inner wall of the longitudinal steel pipe 11, and second stiffening ribs 113 fixedly connected to the inner wall of the longitudinal steel pipe 11 are arranged below the first stiffening ribs 112 to enhance the local stiffness and stability of the longitudinal steel pipe 11 and restrict the concrete expansion under the compression condition of the bridge tower.

[0042] For further information, see Figure 3A pouring hole 131 is commonly provided on the connecting plate 13 and the longitudinal steel pipe 11. An exhaust hole 132 is also commonly provided on the side of the pouring hole 131. The inner diameter of the pouring hole 131 is larger than the inner diameter of the exhaust hole 132. The longitudinal steel pipe 11 is connected to the oblique steel pipe 14 through the pouring hole 131 and the exhaust hole 132 to ensure smooth filling of concrete and prevent the formation of voids.

[0043] Specifically, it also includes a concrete layer 2 cast at the position of the main frame 1. The concrete layer 2 is cast and shaped through a formwork. The main frame 1 is covered with concrete on the outside of the bridge tower to form a thin-walled tower limb. In this way, the deadweight of the structure is reduced and the corrosion resistance of the main frame 1 is improved. The outside of the concrete layer 2 is a streamlined rounded corner setting to minimize wind resistance. A certain height difference is reserved between the casting height of the concrete layer 2 and the top of the main frame 1. The top of the concrete layer 2 is about 30cm lower than the top of the main frame 1. After the upper group of main frames 1 is prefabricated, it is fixed with the reserved part of the lower group of main frames 1 by connecting with a flange 3, the top of the concrete layer 2 is roughened, and the next section of the structure is cast.

[0044] Further, such as Figure 5 and Figure 6 As shown, the bridge tower structure includes flanges 3 installed at both ends of the longitudinal steel pipe 11, and the flanges 3 are used to connect and fix multiple groups of main frames 1 arranged longitudinally. Multiple groups of connection holes 31 are opened on the flanges 3, and the multiple groups of connection holes 31 are distributed in a circular array, and the positions of the connection holes 31 on the upper and lower groups of flanges 3 correspond to each other, so that the upper and lower groups of flanges 3 are connected by bolts to realize the connection of the upper and lower groups of main frames 1.

[0045] Furthermore, the above-mentioned bridge tower structure also includes a guide assembly 4 arranged outside the longitudinal steel pipe 11, and the guide assembly 4 is used for guiding when another group of main frame 1 is installed above the main frame 1. The guide assembly 4 includes a first positioning block 41 fixedly connected to the outer wall of the longitudinal steel pipe 11, the first positioning block 41 is fixedly connected to the flange 3 arranged at the bottom of the longitudinal steel pipe 11, and the first positioning block 41 moves synchronously with the longitudinal steel pipe 11. A guide sleeve 42 is installed in the first positioning block 41, and a guide rod 43 is slidably connected in the guide sleeve 42, so as to facilitate guiding through the guide rod 43. A plug rod 44 is fixedly connected to the bottom of the guide rod 43, and a second positioning block 45 is slidably connected to the plug rod 44, one end of the second positioning block 45 is fixedly connected to the longitudinal steel pipe 11, and the second positioning block 45 is fixedly connected to the flange 3 arranged at the top of the longitudinal steel pipe 11, the diameter of the plug rod 44 is smaller than the diameter of the guide rod 43, and the second positioning block 45 is fixed to the side of the fixed longitudinal steel pipe 11, so that the plug rod 44 is inserted in the second positioning block 45, so as to facilitate guiding the main frame 1 above. The upper set of main frame 1 is installed by hoisting. Since hoisting will cause the main frame 1 to rotate, so that the connection hole 31 cannot be aligned, the guide rod 43 can be inserted through the guide sleeve 42 and then the insertion rod 44 can be inserted into the second positioning block 45 to guide and position the hoisted main frame 1 accurately. At the same time, after the upper set of main frame 1 is installed, the first positioning block 41 and the second positioning block 45 can be used to strengthen the structural strength while the upper set of concrete layers 2 are poured.

[0046] Finally, see Figure 7 and Figure 8The above-mentioned bridge tower structure includes an adjustment mechanism 5 installed on the main frame 1, and the adjustment mechanism 5 is used to adjust the position when hoisting a group of main frames 1 above. The adjustment mechanism 5 includes first clamps 501 respectively installed on two groups of horizontal steel pipes 12 arranged opposite to each other, and the first clamps 501 are connected and installed on the horizontal steel pipes 12 by bolts. A synchronization plate 510 is fixedly connected between the two groups of first clamps 501, so that the two groups of first clamps 501 will not rotate. A fixed plate 502 is fixedly connected to the bottom of the first clamp 501, and the position of the fixed plate 502 is fixed. Multiple groups of first reinforcing plates 511 are fixedly connected between the fixed plate 502 and the first clamp 501, which are used to strengthen the stability of the fixed plate 502 and prevent the fixed plate 502 from deformation. A threaded rod 503 is rotatably connected to the fixed plate 502, and the threaded rod 503 rotates in place. A rotating plate 509 is fixedly connected to one end of the threaded rod 503 away from the center of the main frame 1, and the setting of the rotating plate 509 facilitates the rotation of the threaded rod 503. The threaded rod 503 is threadedly connected with a threaded sleeve 504. When the threaded rod 503 rotates, the threaded sleeve 504 is driven to move along the length direction of the threaded rod 503. The outer side of the threaded sleeve 504 is rotatably connected with a mounting frame 505 to facilitate the deflection of the threaded sleeve 504. Sliding plates 506 are installed on both sides of the mounting frame 505. The end of the sliding plate 506 away from the mounting frame 505 is slidably connected with an adjustment plate 507. When the threaded sleeve 504 moves, it drives the mounting frame 505 and the sliding plate 506 to move. At the same time, the sliding plate 506 and the adjustment plate 507 are slidably matched to make the adjustment plate 507 deflect. The top of the adjustment plate 507 is fixedly connected with a second clamp 508, and the second clamp 508 is rotatably connected to the transverse steel pipe 12 to facilitate the rotation of the adjustment plate 507. Multiple sets of second reinforcing plates 512 are fixedly connected between the adjustment plate 507 and the second clamp 508 to strengthen the structure and prevent the adjustment plate 507 from bending. Therefore, after the rotation, the adjustment plate 507 contacts the inner side of the concrete layer 2 and moves the upper group of main frames 1 through the reaction force, which facilitates easy position adjustment, avoids excessive manpower consumption caused by manually pushing the main frames 1, and prevents safety accidents.

[0047] In this embodiment, the main frame 1 is first prefabricated as a whole in the factory, including the longitudinal steel pipe 11, the transverse steel pipe 12, the connecting plate 13, the oblique steel pipe 14, the first stiffening rib 112 and the second stiffening rib 113, which are fixed to each other by welding. After that, concrete is poured inside the longitudinal steel pipe 11, the transverse steel pipe 12 and the oblique steel pipe 14, and the prefabrication is completed after the bolts 111 are welded to the outer wall of the longitudinal steel pipe 11. The prefabricated main frame 1 is transported to the construction site in sections, and installation preparations are carried out on site. After the first group of main frames 1 at the bottom is fixed, a template is set on its outside to complete the pouring of the concrete layer 2. After the pouring of the concrete layer 2 is completed, the concrete layer 2 is cured.

[0048] Then, the second main frame 1 is hoisted above the first main frame 1 by a crane. After the second main frame 1 is close to the first main frame 1, the adjustment mechanism 5 is installed on the horizontal steel pipe 12 by bolts. At this time, since the second main frame 1 is hoisted by the crane, the rotating plate 509 can be rotated to drive the threaded rod 503 to rotate. After the threaded rod 503 rotates, the threaded sleeve 504 is driven to move along the length direction of the threaded rod 503, and the adjustment plate 507 is driven to deflect through the installation frame 505 and the sliding plate 506. Therefore, after the adjustment plate 507 contacts the inner side of the concrete layer 2, the hoisted second main frame 1 can be moved by the reaction force.

[0049] Insert the guide rod 43 into the guide sleeve 42, and rotate the rotating plate 509 to adjust the position of the second group of main frame 1 being lifted, so that the insertion rod 44 can be inserted into the second positioning block 45. Then, in the same way, insert multiple groups of guide rods 43 through the guide sleeve 42 and then insert the bottom insertion rod 44 into the second positioning block 45, so that the second group of main frame 1 is accurately positioned, so that after the crane lowers the second group of main frame 1, the installation position is accurate, and multiple groups of flanges 3 are connected by bolts passing through the connecting holes 31, and then the adjustment mechanism 5 is disassembled and the guide rod 43 is taken out at the same time. The top of the first group of concrete layer 2 is roughened, the template is installed, and the second group of concrete layer 2 is poured. After that, the second group of concrete layer 2 is cured, and the subsequent main frame 1 is installed and the concrete layer 2 is poured and cured to form the bridge tower body.

[0050] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
