Description

one

The invention relates to construction and installation technology and may not be used for installation of high-rise flexible structures such as radio masts, chimneys, etc.

The aim of the invention is to improve the safety of work by increasing the stability of the assembled structure during installation.

Figure 1 shows the device, side view; figure 2 - section aa in figure 1; on fig.Z - section BB in figure 1 on figure 4 - section bb In figure 1; figure 5 - section GG in figure 1,

The device for mounting high-rise structures contains a base, made in the form of a portal of tubular racks 1, rigidly interconnected by a bolt 2, on which sliding lugs 3 and a working platform 4 are installed. The portal is equipped with a lifting device including a cargo platform 5 connected with chain hoops 6 with a dead bolt 2. On the load platform 5, sliding stops 7, in contact with posts 1, as well as stops 8 for fixing the base of the building section under construction, tap blocks 9 and equalizing blocks 10 with a channel that are fixed are fixed Volume 11, connected to Hbw with winches 12, In the tubular uprights 1 are inserted telescopically assembled uprights 13 and 14 of pipes of smaller diameter. To the racks 13 and 14 are rigidly attached at one end of the pipe 15, in which inserted rods 16, connected in pairs by a beam 17 with a saddle, are inserted. The pipes 15 and the caps 17 are provided with clamps 18. The pipes 15, the rods 16 and the beams 17 form a sliding bolt in each portal with means for fixing it (clamps 18). The racks 13 and 14 are attached to blocks 19 of the cable block estimate for lowering the portals during dismantling of the device, covered with a cable 20 connected with a winch 21. With the turn of the racks 1 of the portal and the racks 13 and 14 of the sliding portals, the braces 22 fixing the supporting portal and retractable portals during installation of the structure 23.

Depending on the shape and mass of the erected structure, the device portals can be made of three-rack, four-rack, etc.

The device works as follows.

After the upper section of the mounted structure 5 is mounted on the loading platform 5 and its base is fixed by stops 7 and 8, winch 12 is connected by means of the tackle 6 to the loading platform 5, which rises along with the upper section of the structure mounted on it. tipping over when lifting with stops 7 and 8; cargo platform, and at the top - sliding lugs 3. Cargo platform 5 5 rises to the passage of the connecting flange section is slightly above the sliding lugs 3, which are brought. Under the connecting flange, and the cargo platform 5 is lowered,

20a, the construction section rests on the stops 3. The platform is released from the cargo platform to the bottom of the portal when the winch 12 is lowered, the second section is installed from the top of the assembly and it is lifted to dock with the upper flange of the previously raised section, after which the sliding rods 16 bolts of the upper portal are installed above

30 connecting flange so that

the seats after the joining of the beams 17 were in contact with the surface of the first section of the structure. Then, the winch 12 is turned on and the two connected sections are lifted, while under the influence of the flange on the deadbolt, the legs 14 are extended and the sliding deadbolt holds the upper structure assembly along the entire lifting path.

0 After the racks are fully raised 14

retractable portal it is fixed by braces 23 to the project foundations. When raising the third section, together with the previous sections, the sliding bolt of the uprights 13 is mounted, as on the uprights 14, above the connecting flange of the second section with the third. When a structure with a third incremental section is lifted under the influence of a flange on a bolt, pillars 13 are put forward, the bolt of which holds the second Russian pole as it rises. Retractable racks with sliding bolts keep the structure from tilting at

55 rise.

Upon completion of the installation of the structure from the ground using a rope (not shown) is removed from engagement with the elements of 45

gels, anchors 18 and by means of a electro-drip system 19, 20, connected to the winch 21, lower the stands 13 and 14 into the tubular stands 1 of the gantry, after which the device can be moved to erect another structure

The number of sliding U-shaped frames or portals formed by the legs 13 and 14 and the sliding bolts involved in the work is determined by

the height of the erected structure and corresponds to the number of sections to be reformed, which creates a system of reliable supports along the entire height of the erected structure.

Such an embodiment of the device significantly speeds up the installation of high-rise structures, ensuring the stability of the installation and thereby increasing the safety of work.
