Description

  :. . one

The invention regards the 3S production of large-sized large-sized constructions, mainly cylindrical tanks.

There is a method shgotbvdevvd inlingg rycheekih tanks of a large diameter with a curtain of aagbt & a vodb vdb, fold it. in the coil, transported, on the MeiCTO assembly, installed on the bottom, unwrap the coil with the help of a tension bag and then successively fix the lower KpONOsy panel l:

But the well-known soooooooooooo much cylindrical cut; large-diameter headholes, as well as increasing reservoirs, increases the measure of the capacity, increasing the weight of {Clone), which makes it difficult to carry out work and makes it necessary; power.

The circuit of the invention is an increase in productivity and convenience of transporters. ki ...:

This chain is achieved by the fact that the cloth is made from parts, each of which is folded into an OTV dap roll, both rolls are on the bottom of the mustache;) they are folded so that the cloths are rolled up opposite, before unfolding: the sheets are joined and the sheets are grilled together, Revolving rolls around the bottom perimeter is provided in opposite sides.

FIG. 1 shows the rolls of the rolls during their installation on the bottom; FIG. 2 shows the position of the rolls during unfolding} in FIG. 3 - rolls placement option.

On the bottom 1 of the tank, on the mounting devices 2 and 3, rolls 4 and 5 are mounted, which are the opposite side of the sheet 6, the size of which corresponds to the size of the wall of the tank.

Rupons 4 and 5 can be set to fit an intermediate or at the same time. Next, dock and weld the free two rupon.

In the process of unrolling the rolls around the perimeter of the bottom, the opposite edges of the dropoirta yizhtpoy edge are welded to the bottom.

The unfolding of the KJT roosters with the help of tensioning cables (on hell, not shown).

With a large height of the cloth, in order to hold its upper edge between unrolling rolls, it is enough to secure it with a cable from the outside of the tank. -g l., ..-.-.;:, -; ":; ji ;;; about

Ø the proposed method, the process of unfolding ropoyov osuiybtZHYZt continuously, but it is possible to turn first one half of the cloth, and then dfZfygoy.

The cloth of the required length can be obtained directly at the site of the “Preparation of springs. In this case, pootkish rolled up in two ruyoya, directed towards each other

When turning the rolls, located on the outer side of the bottom perimeter, the denser edge of the bottom edge of the cloth to the bottom of the tank is achieved, ensuring a reverse other edge of the cloth, which increases its durability and performance as the wall of the tank.

This method reduces the weight of the roll to be doubled and speeds up the installation work, since the roll is unfolded in two directions.

Lazobrene Shape

A method of manufacturing cylindrical tanks of large diameter in which the cloth is made, rolled up into a roll, transported to the installation site, mounted on the bottom, unfolded the roll with the help of a tensioning mechanism and successively fix the bottom edge of the cloth, characterized in that in order to increase productivity and ease of transport, the cloth is made of 2 parts, each of which is rolled up into a separate

The rolls, both rolls on the bottom are set so that the sheets are rolled up in opposite directions. Before the roll unfolds, the butt is welded together and the rolls are turned around the bottom of the perimeter in opposite directions. Sources of information taken into account in the examination
