[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0047] The embodiment of the present application provides a main tower beam support structure system, which can solve the problem in the related art that the truss structure of the ground support cannot adapt to the changes in the chamfers of the middle beam and the upper beam, so the construction of the upper, middle and lower beams adopts three sets of support structures, which requires a large amount of materials, has a relatively complex structure, and is difficult to install and disassemble.

[0048] See also Figures 1 to 8As shown, the embodiment of the present application provides a main tower beam support structure system, including: a support device, a discharge device 4, a main frame body 2 and a sub-frame body 3; wherein the support device is installed in the main tower 1, and the discharge device 4 is arranged on the support device, and the discharge device 4 includes but is not limited to a sand box; the main frame body 2 is arranged to include a main truss 20 and a first matching section 21 and a second matching section 22 which are sequentially detachably connected to both ends of the main truss 20. In the present application, the first matching section 21 and the second matching section 22 are located at each end of the main truss 20, and each of the first matching sections 21 and the second matching sections 22 are provided with at least one group, and the first matching section 21 and the second matching section 22 are provided at least one group. The first and second matching sections 21 and 22 are detachably connected to each other and the height of the first and second matching sections 21 and 22 is lower than that of the main truss 20. Then, a sub-frame body 3 is connected to both sides of the top of the main frame body 2. The sub-frame body 3 includes a sub-truss 30 and a first adjusting section 31 and a second adjusting section 32 which are detachably connected to one end of the sub-truss 30 in turn. The number of the first adjusting section 31 and the second adjusting section 32 is adapted to the first matching section 21 and the second matching section 22, and one group is provided for each of the sub-truss 30 and the sub-truss 30 and the first adjusting section 31 and the second adjusting section 32 are detachably connected by bolts.

[0049] Before the construction of the cross beam of the main tower 1, the supporting device, the unloading device 4, the main frame 2 and the auxiliary frame 3 are prefabricated in advance. Then, at the construction site of the main tower 1, before the construction of the lower cross beam 10, the middle cross beam 11 and the upper cross beam 12, the supporting device is first installed at the bottom of the main tower 1, and then the unloading device 4 is installed on the supporting device. The main truss 20, the first matching section 21 and the second matching section 22 are hoisted to the installation position on the unloading device 4 in turn, and the first matching section 21 and the second matching section 22 are connected to the two ends of the main truss 20 in turn through the pin shaft; then the auxiliary truss 30 and the first adjustment section 31 and the second adjustment section 32 are connected to both sides of the main frame 2 in turn by hoisting.

[0050] At this time, the crossbeam support of the main tower 1 is built at the bottom of the main tower 1, and the bottom formwork system 33 is installed on the top of the built main frame 2 and the auxiliary frame 3. The bottom formwork system 33 is composed of steel plate concrete. The bottom formwork system 33 pre-presses the crossbeam support of the main tower 1 to eliminate assembly gaps and inelastic deformation; then the first layer of concrete is poured on the bottom formwork system 33, and after the concrete reaches the design strength, the prestressed steel strands are temporarily tensioned, and then the second layer of formwork is erected to tie the steel bars, and concrete is poured and cured until the concrete strength reaches the design requirements. At this time, the concrete structure formed is the lower crossbeam 10, and the prestressed steel strands of the lower crossbeam 10 are tensioned to the design requirements, and the pipeline is grouted and cured to the design strength, thereby completing the construction of the lower crossbeam 10. Afterwards, the dismantling device 4 is used to dismantle the crossbeam support of the main tower 1, and the main truss 20 and the first matching section 21 and the second matching section 22, the auxiliary truss 30, the first adjustment section 31 and the second adjustment section 32 can be easily disassembled and assembled; therefore, the second matching section 22 and the second adjustment section 32 are first disassembled, and then the remaining main trusses 20 and the first matching section 21, the auxiliary trusses 30 and the first adjustment section 31 can be reused for the construction of the middle crossbeam 11. After the construction of the middle crossbeam 11 is completed, the first matching section 21 and the first adjustment section 31 are disassembled, and the remaining main trusses 20 and auxiliary trusses 30 are reused in the construction of the upper crossbeam 12.

[0051] Therefore, a set of main frame 2 and auxiliary frame 3 structures can be reused during the construction of the lower beam 10, the middle beam 11 and the upper beam 12, reducing material input and facilitating installation and disassembly.

[0052] The unloading device 4 and the bottom form system 33 provided in addition can also be reused, but due to the heavy weight of the lower cross beam 10, the support device used in the construction of the lower cross beam 10 is different from the support device used in the construction of the middle cross beam 11 and the upper cross beam 12. The cross beam support structure system of the main tower 1 includes two support devices with different structures, one of which is the first cross beam support system 5 for casting the lower cross beam 10; the other support device is the second cross beam support system 6 for casting the middle cross beam 11 and the upper cross beam 12.

[0053] In the present application, the first crossbeam support system 5 includes: a steel pipe column 50, an inclined column 51 and a vertical column 52, wherein the steel pipe column 50 is located at both ends of the main frame 2, and the steel pipe column 50 is supported by the second matching section 22; one end of the inclined column 51 is fixed to the main tower pedestal 13, and the other end is inclined toward the main truss 20 and supported by the main truss 20; the vertical column 52 is located between the steel pipe column 50 and the inclined column 51, one end of the vertical column 52 is fixed to the main tower pedestal 13, and the other end is supported by the end of the main truss 20.

[0054] Before constructing the supporting device, the main tower base 13 is constructed first, and embedded parts 54 are provided in the main tower base 13. Then, when installing the steel pipe columns 50, the inclined columns 51 and the vertical columns 52, the embedded parts 54 are connected to the inclined columns 51 and the vertical columns 52 respectively, thereby effectively fixing one end of the steel pipe columns 50, the inclined columns 51 and the vertical columns 52 to the main tower base 13 first.

[0055] In the present application, an intermediate flat joint 53 is connected between the two steel pipe columns 50, and the top surface of the intermediate flat joint 53 is flush with the top surface of the steel pipe column 50, and then a discharge device 4 is provided at the top of the inclined column 51 and the vertical column 52, and the discharge device 4 is placed on the intermediate flat joint 53. The provision of multiple discharge devices 4 effectively improves the support stability of the support structure at the lower cross beam 10, and is more stable during the unloading process. The intermediate flat joint 53 can also balance the upper horizontal force well, thereby further improving the overall stability of the lower cross beam 10. A discharge device 4 is also installed on the steel pipe column 50.

[0056] In the present application, the second crossbeam support system provided includes: a corbel body 60 and an installation assembly, the corbel body 60 is detachably connected to the inner walls of the two main towers 1, the second adjustment section 32 is supported by the corbel body 60, and the unloading device 4 is installed on the top of the corbel body 60; the installation assembly is connected between the main tower 1 and the corbel body 60.

[0057] During use, after the construction of the lower cross beam 10 is completed, during the process of dropping the main frame 2 and the auxiliary frame 3, the bracket body 60 and the unloading device 4 are installed at the construction position of the upper cross beam 12 through the installation assembly, wherein the unloading device 4 is disassembled and reused after the construction of the lower cross beam 10 is completed. After the construction of the middle cross connection is completed, the bracket body 60 and the unloading device 4 can be reused in the construction of the upper cross beam 12, and reused to reduce material input.

[0058] In the present application, the installation components include: an anchor plate 61, a positioning plate 62, and a pre-embedded climbing cone 63. The anchor plate 61 is pre-embedded in the main tower 1. The positioning plate 62 is located in front of the anchor plate 61 and is pre-embedded in the main tower 1. The pre-embedded climbing cone 63 has one end passing through the anchor plate 61 and the anchor plate 61, and the other end extending to the inside of the main tower 1 and connected to the corbel body 60. The corbel body 60 has a simple structure, is easy to install, and is firm. When the corbel body 60 is to be disassembled, the nut on the pre-embedded climbing cone 63 can be removed, and the remaining part can be directly cut off.

[0059] In the present application, in order to conveniently reuse the main frame 2, the auxiliary frame 3, the corbel body 60 and the unloading device 4 from the construction of the lower beam 10 to the construction of the middle beam 11 and the upper beam 12 in sequence, the main frame 2 is firstly provided with two pieces, and a connecting rod system 200 is provided between the two pieces of the main frame 2.

[0061] In the present application, the traction device provided includes a slide beam 70 and a pulling assembly 71, wherein the slide beam 70 is connected to the unloading device 4, and the axial direction of the slide beam 70 is perpendicular to the axial direction of the main frame 2, and the pulling assembly 71 is connected to both ends of the slide beam 70, and the traction ends of the two pulling assemblies 71 are respectively connected to the two main frames 2.

[0062] During use, after the main frame 2 is dropped from the frame, the pulling assemblies 71 at both ends of the slide beam 70 respectively pull the two main frame bodies 2 toward the two ends of the slide beam 70 to slide synchronously, and the force on the slide beam 70 is balanced until the main frame 2 moves to the predetermined position. Then, the first matching section 21 or the second matching section 22, the first adjustment section 31 or the second adjustment section 32 are disassembled, and are lifted to the construction positions of the middle beam 11 and the upper beam 12 in sequence by using the tower crane as a whole.

One end of the steel strand 712 passes through the through-hole jack 711 and is connected to the through-hole jack 711. The other end of the steel strand 712 is connected to the main frame 2.

[0064] During use, the steel strand 712 is connected to the through-hole jack 711 and the main frame 2, and the through-hole jack 711 and the reaction seat 710 push against each other, thereby partially driving the main frame 2 to move.
