Description

one

The invention relates to construction scaffolding, in particular, suspended string scaffolding for the construction of frame buildings, structures, mainly of great height.

. Suspended scaffolding for insulating works on pipelines located on racks, including working platforms with fences and detachable hangers with detachable fingers installed in the places of the connector with an eccentric neck and fixing protrusion on one side, and on the other arm, and suspensions are known. equipped with a towbar Ij. The disadvantage of these forests is the inability to move work sites vertically.

String forests are known for finishing the surface of buildings, including strings, shield flooring and fences 2,

The disadvantage of these forests is the high labor costs for the installation and disassembly of forest elements produced exclusively by hand.

The closest technical solution to the proposed is

string forests, including working platforms with fences and articulated 4I between them pendants and strings 3.

The disadvantage of these forests is the lack of consistency in the passage of the supporting rims of the strings in the rootstocks through the double gate valves, which prevents the automation of lifting

10 and lowering of the working sites to the new Rus.

The purpose of the invention is to increase productivity and improve operational reliability when moving work sites vertically.

To achieve this goal, the suspension of each working platform is designed as interconnected

20 by a horizontal beam of two vertical racks of box-section, having box-shaped guides adjacent to their end walls, made with through-holes,

25 are also loaded with latches located inside the racks and interacting with the strings passed through the rails.

FIG. 1 shows stringed forests of 3 articulated plots.

pendants, strings; in fig. 2 - the same, the top view of the A-A; in fig. 3 shows a section BB in FIG. one; in fig. 4 is a sub-scaffolding of the scaffolding in the working position; FIG. 5 - a fragment of the suspension elements in the process of raising forests to Rus; in fig. b - the position of the latch at the beginning of the descending of forests; in fig. 7 position with automatic rotation of the latch in the process of lowering forests; in fig. 8 - fragment of a hinged string.

The string scaffolding consists of working platforms 1, suspensions 2 and strings 3.

Lifting, lowering of working platforms and hangers to the new Rus is carried out with the help of one crosshead 4, which is moved from the suspension to the suspension on a crane hook or hoist.

The working platform is made of frame 5, working deck 6 and fence 7. PciMa is made of two longitudinal support beams 8 connected for rigidity by transverse beams. The lugs 9 are made at the ends of the beams, and the dimensions between the inner edges of the lugs on one side of the beams are 3-4 mm larger than the size between the outer edges of the openings at the other ends of the beams. The ends of the beams are articulated with the suspension from to. by the power of two fingers 10, located coaxially on one, horizontal axis.

Suspension 2 is made of two vertical pillars 11, fastened together by a horizontal beam below 12. The pillars on the outside have two through vertical guides 13 with funnels 14 at the ends. In the pillars of the suspension, horizontal two axles x15 have two-armed spring-loaded latches 16. Windows 7, 18 are made on the outer faces of the racks with an exit to the side of the rails, for opening the ends of the latches, and window 19 is made on the inside of the racks.

The strings 3 are made of links 21, interconnected sharnarno earrings 22. Each link of the string

made of two rods 23, bent at the ends., which are attached to the tips 24, which have slots for the bolt 25 studs and nuts 26. Support brackets 27 are attached at equal intervals between two parallel rods.

String forests work as follows.

As the scaffold 2 rises, the spring-loaded latches 16, meeting with the support brackets 27 of fixed strings in the cavity of the through guides 13, are first automatically pressed, then latched, thereby providing an automatic

reliance of the scaffolding on the strings when the suspension is lowered and the load hook is released from the load.
