[0003] When installing the inverted triangle tube truss of the tree structure, the conventional method is to use temporary support high-altitude installation or ground assembly overall hoisting. Both methods are difficult to construct and have high construction costs. If the split hoisting method is used, the stability of the truss section hoisted in advance is poor, and it is easy to overturn and local deformation. Summary of the invention

[0014] Furthermore, the support frame includes a mounting seat and a support platform, the support platform is fixed on the mounting seat, and the mounting seat is mounted on the upper chord steel pipe of the main truss and is suitable for sliding.

[0015] The beneficial effects of the present invention are:

[0016] 1. Before the main truss is lifted, the sliding device is firmly placed on the tree-shaped column, and then the main truss is hoisted and placed on two adjacent tree-shaped columns. The position of the main truss can be adjusted by sliding the sliding device, and then the main truss is fixed by the fixing device.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Reference Figure 1 and 2, as a support system for the installation of a tree-shaped column structure provided by an embodiment of the present invention, it is suitable for being erected between two tree-shaped columns 5, and includes a main truss 1, a sliding device 2 and a fixing device 3. The main truss 1 is erected on the two tree-shaped columns 5; there are at least two sliding devices 2, and each of the adjacent tree-shaped columns 5 is provided with a sliding device 2. The main truss 1 abuts against the sliding device 2 and is slidably connected to the sliding device 2; the fixing device 3 is arranged on one side of the main truss 1, one end of which is fixed on the main truss 1, and the other end is fixed on the branch rod of the tree-shaped column 5.

[0037] Before the main truss 1 is lifted, the sliding device 2 is firmly placed on the tree-shaped column 5, and then the main truss 1 is hoisted and placed on two adjacent tree-shaped columns 5. The position of the main truss 1 can be adjusted by sliding the sliding device 2, and then the main truss 1 is fixed by the fixing device 3. After the main truss 1 is fixed, the connecting truss can be hoisted, and the connecting truss segment can be temporarily placed on the support system. Workers can operate and construct on the main truss 1, and weld the connecting truss to the tree branch rod of the tree-shaped column 5. When the connecting truss is fixed, the fixing device 3 is released, the main truss 1 is slid to the top of the next tree-shaped column 5, the position of the main truss 1 is adjusted, and the main truss 1 is fixed to the tree branch rod of the new tree-shaped column 5 by the fixing device 3, and the installation of the remaining connecting truss segments is completed in sequence in the above manner. The support system in the present application can realize the stable installation of the tree-shaped column 5 structure, and can effectively avoid problems such as overturning and local deformation during the installation process.

[0038] Specifically, refer to Figure 3 and 4 The main truss 1 is an inverted triangle truss structure, and its structure should have high rigidity. Its length can be determined based on the distance between two adjacent tree-shaped columns 5 plus sufficient support space. The triangle truss has good stability and is not easy to deform. The sliding device 2 includes a base 21 and a pulley 22. The base 21 is fixed on the tree-shaped column 5, and the pulley 22 is convexly arranged on the base 21 and rotatably connected to the base 21. A groove 221 is arranged on the side of the pulley 22, and the groove 221 is arranged around the pulley 22. The lower chord steel pipe of the main truss 1 is embedded in the groove 221. By arranging the groove 221 on the pulley 22, the installation position of the main truss 1 can be limited to keep it in a good horizontal degree. At the same time, after rotating the pulley 22, the main truss 1 can be driven to slide in a predetermined direction. The size of the groove 221 on the pulley 22 is determined by the size of the lower chord steel pipe of the main truss 1 that can be flexibly placed. The pulley 22 and its sliding shaft should be able to withstand all the vertical loads carried by the main truss 1.

[0039] Furthermore, the fixing device 3 includes a connecting rod 31 and a fixing sleeve 32 connected to each other. The end of the connecting rod 31 is connected to the main truss 1. The fixing sleeve 32 is sleeved on the branch rod of the tree-shaped column 5 and has a diameter suitable for adjustment.

[0040] Specifically, refer to Figure 5 and Figure 6 , the end of the connecting rod 31 is hinged on the main truss 1, and the connecting rod 31 is fixedly connected to the fixing sleeve 32. The fixing sleeve 32 includes an arc-shaped first buckling portion and an arc-shaped second buckling portion, and the first buckling portion and the second buckling portion are connected by a fastener. With the above structure, the position angle and diameter of the fixing sleeve 32 can be adjusted, so that the fixing sleeve 32 can be mounted on tree branch rods of different sizes, thereby increasing the applicability of the fixing sleeve 32. Because the branch pipe specifications and angles of different tree-shaped columns 5 are different, the fixing device 3 is designed to be adjustable. The fixing devices 3 are at least four groups, each group is two, and the two fixing devices 3 are symmetrically arranged on both sides of the upper chord steel pipe of the main truss 1.

[0041] As a variable embodiment, refer to Figure 7 Alternatively, the end of the connecting rod 31 may be fixed to the main truss 1, and the connecting rod 31 is hinged to the fixing sleeve 32. This structure can also meet the position angle adjustment of the fixing sleeve 32.

[0042] Furthermore, the support system further comprises a support frame 4 , which is disposed on the main truss 1 and is suitable for sliding on the main truss 1 .

[0043] Specifically, refer to Figure 8 and 9 The support frame 4 includes a mounting seat 41 and a support platform 42. The support platform 42 is fixed on the mounting seat 41. The mounting seat 41 is mounted on the upper chord steel pipe of the main truss 1 and is suitable for sliding. The sliding mounting seat 41 can be fixed to the main truss 1 by fasteners such as bolts. When hoisting the connecting truss section, the connecting truss section can be temporarily fixed on the support frame 4, and the support frame 4 plays a role of temporary support.

[0044] The use process of the support system in this embodiment is as follows: during construction, the sliding device 2 is first arranged on the tree-shaped column 5 and adjusted in position, and then the main truss 1 is hoisted, and the lower chord tube of the main truss 1 is placed on the groove 221 of the pulley 22 of the sliding device 2, and the horizontality of the main truss 1 is adjusted, and then the fixing device 3 is adjusted to fix the main truss 1 on the tree-shaped column 5. Then the position and height of the support frame 4 are determined according to the actual situation of the installed inverted triangle connecting truss section. After all the above are completed, the connecting truss section can be hoisted, and after the position and accuracy of the connecting truss section are adjusted, the two upper chord rods of the connecting truss section are temporarily erected on the branch rods of the tree-shaped column 5 to ensure the stability of the connecting truss section. At this time, the welding connection construction between the connecting truss section and the tree-shaped column 5 can be carried out. After the construction is completed, loosen the fixing device 3, slide the main truss 1 to the top of the next tree-shaped column 5, adjust the position of the main truss 1 and fix the main truss 1 to the branch rod of the new tree-shaped column 5 through the fixing device 3, and complete the installation of the remaining connecting truss sections in the above manner.

[0045] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
