[0059] Install the second row of formwork 10: move the movable part 22 of the second transition suspension beam 20 away from one side of the second row of formwork 10, tilt the formwork 10 from bottom to top, place one side of the formwork 10 on the supporting plate 23 of the first transition suspension beam 20, align the lifting grooves 15 of the second row of formwork 10 with the lifting grooves 15 of the first row of formwork 10, then lift the other side of the second row of formwork 10 until it is horizontal, move the movable part 22 of the second transition suspension beam 20 so that the rod part 24 of the movable part is embedded in the lifting groove 15 of the second row of formwork 10, at this time the supporting plate 23 of the second transition suspension beam 20 supports the second row of formwork 10; during this process, when one formwork 10 is installed, the newly installed formwork 10 is tightly attached to the side of the already installed formwork 10, and the two formworks 10 are fastened and connected through the fastening member penetrating the connecting hole 14, the lifting grooves 15 of the first row of formwork 10 and the second row of formwork 10 are spliced into a lifting hole, the rod part 24 of the movable part penetrates the lifting hole, and the supporting plate 23 simultaneously supports the two rows of formwork 10. The movable part 22 of the transition suspension beam 20 can move horizontally along the direction perpendicular to the length of the steel bar truss 21, which facilitates installation and avoids interference of the supporting plate 23 below with the installation of the formwork 10.

[0060] Install the third row of formwork 10: the installation method is the same as that of installing the second row of formwork 10, and all formworks 10 are installed as shown in Figure 13 .

[0061] Then install the support assembly 30, as shown in Figures 6-7 , the support assembly 30 includes a plurality of vertical rods 31, horizontal rods 32, and top supports 33, the top supports 33 support the edges and corners of the formwork array; the vertical rods 31 are connected by the horizontal rods 32, and the vertical rods 31 and the main beam scaffold 43 are also connected as a whole by the horizontal rods 32, which improves the overall stability of the support assembly 30, and according to actual needs, diagonal braces can be added, during installation, rotate the adjusting nuts to adjust the height of the top supports 33 so that the top supports 33 just abut the bottom surface of the formwork 10, as shown in Figure 13 , the state of all support assemblies 30 after installation.

[0062] Finally, remove the transition suspension beam 20; rotate the nuts 24, remove all nuts 24 and supporting plates 23 from below, and remove the horizontal beam body 21 and the supporting part 25 from above, which are all recycled, Figure 14 , the state of the transition suspension beam 20 after removal.

[0064] Pour concrete and maintain;

[0065] After curing and forming, the support assembly 30, the first fastener, and the formwork 10 are removed for reuse.

[0066] In this scheme, the floor support plate is not needed, the formwork 10 is suspended by the transition suspension beam 20 for transitional hoisting, the use of consumable materials is reduced, and the cost is reduced. The transition suspension beam 20 is prefabricated in the factory and can be directly installed after being transported to the construction site. The formwork 10 can be directly laid on the main beam side form 42 or the supporting plate 23 of the transition suspension beam 20. The formwork 10 is very convenient to lay.

However, the formwork 10 is installed more quickly, and the erection of the support assembly 30 does not need to worry about the problem of inaccurate jacking position. Compared with directly using the steel bar truss, and the steel bar truss is embedded in the concrete as a steel bar, the specification selection of the steel bar truss will be larger than that of the steel bar tied in the construction site. Therefore, this scheme will not cause waste of steel bar materials. In this scheme, the transition suspension beam 20, the formwork 10, and the support assembly 30 can be reused, thereby reducing the cost.

[0067] In actual application, the supporting plate 23 is rectangular. Before the formwork 10 is installed, the supporting plate 23 is rotated so that the long side of the supporting plate 23 is perpendicular to the formwork 10 to be installed. After the formwork 10 is installed, the supporting plate 23 is rotated so that the short side of the supporting plate 23 is perpendicular to the installed formwork 10, thereby reducing the interference of the supporting plate 23 on the installation of the formwork 10, as shown in Figure 12 .

The remaining construction process is similar to that of Embodiment One, which meets the construction needs of different scenes.

[0070] In other embodiments, as shown in Figure 16 , the hoisting groove 15 can be located on the long side of the formwork 10. For example, in Embodiment One, eight transition suspension beams 20 can be used to hoist the long side of the formwork 10, which can also meet the construction needs.

[0071] In other embodiments, the jacking 33 can only support on the edge of the formwork 10.

[0072] In other embodiments, the number, position and shape of the connecting holes 14 and the lifting grooves 15 can be adjusted according to actual conditions to meet the lifting requirements,

[0073] In other embodiments, the movable part 22 can also adopt other structures, such as a sleeve, a slider, etc., as long as the movable part 22 can move horizontally along the length direction perpendicular to the beam body 21.

[0074] In other embodiments, the beam body 21 can also adopt other section steels, such as an I-beam, an H-beam, a square tube, etc., or adopt one of a steel bar truss and a steel truss, as long as the large-span support can be met.

[0075] In other embodiments, the support part 25 adopts a height-adjustable structure, and the height of the beam body 21 can be adjusted as a whole.

[0076] In actual application, the construction of the self-propelled hydraulic lifting vehicle 5 is very convenient, and no full-frame scaffold is needed, workers can stand on the self-propelled hydraulic lifting vehicle 5 to perform installation work, the installation efficiency of the installation workers can be improved, and the workers do not need to climb the scaffold, so the safety is improved.

[0077] In actual application, as shown in Figure 16 The template top surface 11 and the template side surface 12 are internally provided with grid-shaped reinforcing ribs.
