I fc

The invention relates to the construction and can be used in the construction of external walls of monolithic reinforced concrete.

The aim of the invention is the expansion of technological capabilities by providing installation of internal walls and partitions simultaneously with the construction of external walls.

Figure 1 shows the plan of the building being erected; figure 2 is a section a - a in figure 1; fig.Z - node I in figure 1; figure 4 - section B - B in fig.Z; FIG. 5 shows a drum with a concrete conduit and a carriage, a fragment.

Sliding sheathing includes formwork boards 1, jacking frames 2 with jacks 3, loaded working platforms 4, located along the longitudinal walls 5 of the building and equipped with working platforms 6. On the loaded platforms there are fixed bottom guides 7. to which cradles 8 are suspended. .

The jacks 3 are arranged in groups along the longitudinal walls and are fixed on bridges 9 connecting adjacent jacking frames 2.

For supplying and distributing the concrete mix, there are 4 drums 10 installed on the outer working platforms with flexible concrete lines 11 fixed on the carriages 12 moving along the upper guides 13 of the outer working platforms 4. The drums 10 are driven by reversible winches 14 arranged at work sites 6.

For maintenance of the formwork, internal working platforms 15 are provided on the inner side of the erected walls.

The formwork works as follows ..,

The jacks 3, moving over the jack rods 16, lift the formwork panels 1, the outer 4 and the inner 15 working scaffolds and working platforms b. As they rise into the space between the boards 1, the concrete mixture is supplied through the concrete pipe lines 11, the ends of which are fixed to the carriages 12 moving along the upper rails 13 of the scaffold 4.

Finishing of erected walls is made

simultaneously with their erection from the cradles suspended on the rails 13.

During the erection of the walls of the next floor on the previous floor, it is necessary to install internal partitions 17 on the previously installed ceilings 18.

Claims (3)
