Abstract

FIELD: construction.

SUBSTANCE: invention relates to the field of equipment, where fences, levers for zones of movement of personnel of enterprises, ships and vessels, pedestrian zones for ensuring safety of persons of specified categories are used, as well as allocation of zones of organized movement to provide functions of target purpose. Technical result is achieved by the fact that the balustrade module includes a grid formed by plastic bending of the sectional steel profile, wherein the grid includes posts of higher height and lower height, handrails, odd strings and even strings and is made of a single arm of long rolled stock, wherein the post of greater height in its upper part with a curved portion changes into rails, which successively change into odd and even strings, odd strings are turned towards the post of higher height, and even - from it, odd strings are connected to the rails in series with the bent, intermediate part connected to the rack of greater height of the adjacent section, and the bent part, and the even strings are connected to the odd string in series with the bent part, the intermediate part connected to the rack of the higher height of the balustrade module, and the bent part, wherein the last string of the section changes into a post of a lower height by means of a bent part.

EFFECT: technical result of claimed device is reduction of labour intensiveness of balustrade module manufacturing, reduction of waste at its manufacturing.

Description

The invention relates to fields of technology where fences, rails are used to highlight areas of movement of personnel of enterprises, ships and ships, pedestrians in pedestrian zones to ensure the safety of persons of these categories, as well as the allocation of zones of organized movement to ensure the functions of the intended purpose (to exclude movement, for example pedestrians on the lawn).

Known regulatory document [1], which provides a fence consisting of racks, railings, strings, side strip, which are made of profiles connected by welding. The disadvantages of this design are;

- a large volume of operations to obtain blanks from the profile;

- availability of welding:

- performing operations to protect welds and heat affected zones from corrosion or restoring the paintwork in the weld zone, if there is a need to perform corrosion protection at the installation site.

Lime barriers, for example, according to the patent [2], containing panels fixed in the panel holders. The disadvantage of this design and similar to it is a rather complicated design, including panel holders, panels, devices for mounting panels in panel holders.

Fencing is known [3], where a frame is made to which elements cut from a sheet of metal by a CNC plasma cutter are attached. The disadvantages of this design are:

- a large volume of operations to obtain blanks for welding operations,

- a significant amount of welding work,

- performing operations to protect welds and heat affected zones from corrosion.

Known fencing according to the patent [4], containing a frame and a lattice fastened with it, consisting of a combination of closed cells. The cells are formed by plastic bending of a bar of steel bar and winding it in the form of turns, which are then compacted and thereby form closed cells. The disadvantage of this design is the relative complexity of manufacturing (the manufacture of a frame, lattice, the fastening of these structural elements, the connection of the frame with racks, etc.).

The objective of the invention is to reduce the complexity of manufacturing a section of the fence, reducing the volume of waste during its manufacture, maintaining corrosion protection.

1. The specified technical result is achieved by the fact that in the section of the fence containing the lattice formed by plastic bending of the section steel profile, the lattice includes racks of greater height and lower height, railings, odd strings and even strings and is made of a single section of long products, and a stance of greater height in its upper part with a curved section passes into a railing, which sequentially passes into odd and even strings, while the odd strings are deployed towards the stance of a greater height, and the even strings from it, the odd strings are connected to the railing of a successively curved, intermediate part, connected to a stand of greater height of an adjacent section, and a curved part, and even strings are connected to an odd string in series with a curved part, an intermediate part connected to a stand of a higher height of the guard section, and a curved part, while the last string of the section passes into the rack of a smaller height .

2. The fence according to claim 1, in which the intermediate parts are connected to the uprights of greater height using bolted connections.

3. The fence according to paragraphs. 1, 2, in which the minimum vertical gaps are made between the lower strings, as well as the lower string and the pedestrian surface.

The drawing shows a design of the claimed fencing.

In section 1 of the fence 2, containing the lattice formed by plastic bending of the section steel profile, the lattice includes racks of greater height 3 and lower height 4, railing 5, odd strings 6 and even strings 7 and is made of a single section of long steel of height 3 in its upper part, the curved section 8 goes into the railing 5, which sequentially passes into the odd strings 6 and even 7 strings, while the odd strings 6 are deployed towards the rack of greater height 3, and the even strings 7 from it, the odd strings 6 connected to the railing 5 sequentially curved part 9, the intermediate part 10 connected to the stand of greater height 3 of the neighboring section 11, and the curved part 12, and the even strings 7 are connected to the odd string 6 sequentially curved part 13, the intermediate part 14 connected to the stack of larger the height of the fence section 3, and the curved part 15, while the last string 16 of section 1 passes the curved part 17 into a smaller rack height 4.

The fence according to claim 1, in which the intermediate parts 10 and 15 are connected to the uprights of greater height 3 using bolted connections 18.

Fencing 1, 2, in which the minimum vertical gaps are made between the lower strings 16 and 19, as well as the lower string 19 and the pedestrian surface 20.

As shown in the drawings, the sections of the fence are made of plastic deformation of a single bar of long products. Thus, racks, rails, strings, side strip are formed. The last element is formed due to the deformation of the lower strings with a minimum vertical gap between them. To ensure regulatory requirements for the location of the side strip relative to the pedestrian surface (decking) (see, for example, [5]) the lower string is either located close to the pedestrian surface, or with a minimum clearance, or with any clearance that is set in the technical specifications for design.

To ensure the rigidity of the section and the fence, in general, the intermediate parts 10 and 15 are connected to the uprights of greater height 3 using bolted joints 18.

Comparison of the prototype device and the claimed device shows that the claimed fencing section with racks obtained by plastic deformation eliminates such types of work in the manufacture of fencing as marking and cutting workpieces, welding workpieces into a section, preparing sections for painting and painting at least welds , and also allows you to minimize the amount of waste in the manufacture of fencing.
