The formwork installation construction is performed by two micro-cranes 30 and a formwork runner 46 provided in advance on the wall surface.
The specific embodiment of the invention comprises the following steps:
the first step is to build a partition construction platform as shown in fig. 10. The construction platform with a two-layer structure is built by using the platform upright posts 25 and the platform cross beams 26, wherein the platform upright posts 25 are tubular piles with the diameter of 300mm, the height of the tubular piles is 1.6m, the platform cross beams 26 are H-shaped steel with HW 200 x 200, the bottom layer is 2.5m long, and the upper layer is 1m long. The whole construction platform is 1.5m wide, and the platform bottom is provided with a roller 24 which can move along the longitudinal direction of the wall during construction. In order to further ensure the strength of the upper deck, a hoop 28 is mounted on the upper deck beam 26, and a bracket 29 is mounted between the hoop 28 and the upper deck beam 26. After the platform is built, a patterned steel plate 27 is paved on the cross beam so as to facilitate the subsequent worker to move. Two miniature cranes 30 and a steel plate assembling hanger 31 are also arranged on the bottom layer of the platform beam 26. The main structure of the micro-lift 30, excluding the boom, has a planar dimension of 1 x 0.6m and a height of 0.8m. The steel plate spliced hanging bracket 31 has a structure as shown in fig. 11, and is 1m long and 1.2m high, and consists of a rigid support 32, a flexible support 33 and a hanging bracket girder 34. A movable lifting trolley 35 is arranged above the main beam and connected with a lifting hook 36, so that lifting operation in the up-down, left-right direction can be realized. A fixed assembly base 37 is arranged right below the hanging bracket and is made of C15 concrete, and the lifted profiled steel sheet 1 can be sequentially inserted into the base, so that the assembly of the single-sided internal mold is realized.

The profiled steel sheet 1 has a structure as shown in FIG. 1, 24cm on straight edge, 14.14cm on two oblique edges, 45 DEG arrangement and 28mm width. The connecting edge 2 at the two ends is 6cm long, the thick part is 3cm long, the width is 28mm, and the thin part is 3cm long and 14mm wide. The profiled steel sheet 1 was 1m high, and after a plurality of profiled steel sheets 1 were inserted into the base, the construction personnel performed the single-sided internal mold assembly work using bolts 3, and the connection schematic diagram was referred to in fig. 3. The single-sided internal mold is generally formed by assembling 3 profiled steel sheets 1 at one time. Because the strength of the whole internal mold system needs to be enhanced, the vertical keels are required to be pre-buried in advance, and according to the pipeline requirement in the wall, after the single-sided internal mold is assembled, the inner side of the profiled steel sheet 1 needs to be welded with the vertical L-shaped keel slot 6, the pipeline guide channel 7 and the pipeline channel fixing member 8 in advance.
