[0034] The lower truss support 330 and the lower telescopic truss support 450 are adjusted so that the lower truss 310 and the lower telescopic truss 410 are located at the same height position to jointly form a construction plane for the bottom frame formwork structure 500, which is supported on the construction plane and used to connect and support the lower grid formwork group, as shown in Figure 4 To form the well-shaped thin-walled frame structure, the lower grid formwork group is spliced and constructed on the two lower cover surfaces to form longitudinal and transverse intersecting frame pouring channels that communicate with the cover surfaces, and the frame pouring channels form a grid structure, the bottom frame formwork structure 500 includes a cover frame formwork 510 and an internal frame formwork 520, the cover frame formwork 510 is arranged in the cover grid structure, and the internal frame formwork 520 is arranged in the internal frame grid structure, the cover frame formwork 510 and the internal frame formwork 520 each include a transverse inner support 511, a longitudinal inner support 512, a grid core mold 513, and a telescopic support rod 514, the grid core mold 513 is arranged in the middle of the grid structure and is fixed on the construction plane, the transverse inner support 511 is arranged in the transverse direction and is used to support and fix the transverse grid formwork of the bottom frame formwork structure 500, the longitudinal inner support 512 is arranged in the longitudinal direction and is used to support the lower panel inner formwork that extends to the lower frame box structure pouring area and the longitudinal grid formwork of the bottom frame formwork structure 500, and the grid core mold 513 is positioned and supported to connect the transverse inner support 511 and the longitudinal inner support 512 through the telescopic support rod 514, as shown in Figure 4 The number of telescopic support rods 514 is appropriately arranged according to the length of the longitudinal grid formwork and the longitudinal inner support 512, the grid core mold 513 is a square frame, the inside of which is reinforced by diagonal rods, and for longer mold rods, a reinforcing structure 513a is arranged outside the middle of the mold rod to enhance the bending strength, as shown in Figure 4 The reinforcing structure 513a can be a U-shaped square folding rod;

[0035] For the omitted description and drawings, the outer formwork referred to herein uses a conventional composite steel formwork, and the structure and formwork method thereof use the conventional formwork method in the prior art, in addition, the flange frame pouring area does not exist the pouring difficulty and formwork difficulty of the main structure because it is located outside the main structure of the frame structure, therefore, the flange formwork is supported by using the conventional formwork splicing and supporting method;

[0036] After the lower frame box structure 100 is poured, the top support structure can be supported thereon, and the upper rib plate formwork and the lower panel inner formwork are constructed, the top support structure includes an upper rib plate support structure 600 arranged in the transverse direction and an upper panel support structure 700, as shown in Figure 5 and Figure 6As shown, the upper rib plate support structure 600 and the upper panel support structure 700 are adapted to the frame box block structure, and are both trapezoidal structures. The upper rib plate support structure 600 is arranged according to the position of the upper rib plate 220, and a plurality of upper panel support structures 700 are arranged in parallel between the upper rib plate support structures 600,

[0037] Referring again to Figure 5 The upper rib plate support structure 600 includes an upper truss 610, an upper inclined rib support 620, a structural base 630, an upper truss support 640, and an upper inclined rib support 650. The upper truss 610 and the upper inclined rib supports 620 on both sides form a trapezoidal structure support. Due to the large height of the upper frame box structure 200, a one-piece structural base 630 is arranged in the trapezoidal structure support for support. The structural base 630 is fixed to the lower frame box structure 100 and located directly below the upper truss 610. The structural base 630 is vertically supported by the upper truss support 640 at the upper end and vertically supported by the upper inclined rib supports 650 on both sides.

The upper panel inner formwork is supported by the parallel lower panel supports 420 arranged between the two outer ends of the upper rib plate formwork, and forms the interconnected pouring channels of the upper rib plate 220 and the upper cover panel 210. Before the formwork is removed, the lifting truss support 730 drives the lifting truss 710 to descend to a certain height, and the lower panel supports 420 are contracted inward until the lower panel supports 420 are less than or equal to the lower rib plate support structure 300. The lifting truss support 730, the upper panel lateral support 750, the upper panel vertical support 740, and the upper panel lateral support 750 are preferably telescopic hydraulic rods, which are beneficial for large-stroke telescopic adjustment.

[0039] As shown in Figure 7 , the structure and support method of the upper grid formwork group are consistent with those of the lower grid formwork group described above, and will not be described again here.

[0040] Based on the prefabricated formwork system of the wave-eliminating frame box block, a pouring construction process for step-by-step pouring of the frame box block is performed.

The longitudinal and transverse grid forms are respectively supported by the transverse inner supports 511 and the longitudinal inner supports 512. The grid core forms 513 are arranged in the middle of each compartment structure and are installed on the construction platform as support bodies. The four form rods of the grid core forms 513 respectively press the transverse inner supports 511, the longitudinal inner supports 512 and the lower panel inner forms through the telescopic support rods 514 to provide support force. The support points of the telescopic support rods 514 should avoid the form splicing seams.

[0044] III. The outer forms for pouring the lower cover plates 120 are arranged in parallel with the lower panel inner forms. The steel bars are arranged and the lower box structure 100 is integrally poured. When the steel bars are arranged, the reinforcing connection steel bars of the next two pouring bodies should be reserved. In addition, the circular platform nuts and the steel bar straight threaded segments are reserved on the sides of the lower box structure 100 pouring body for splicing and connecting between the frame box blocks.
