Abstract

FIELD: construction engineering.

SUBSTANCE: invention relates to the fields of engineering in which staircase and inclined paths railings and ramp handrails are used. The technical result is achieved in that the staircase railing section which comprises uprights of higher and lesser height, rails, odd strings and even strings formed from a single length of long products, with the higher upright in its upper part with its curved section passing into a railing which consecutively passes into odd and even strings, with the odd strings being turned in the direction of the higher upright and even string being turned from it, odd strings are connected to the railing consecutively by a curved intermediate part which is connected to the higher upright of the adjacent section and to a curved part and even strings are connected to an odd string consecutively by a curved part, an intermediate part which is connected to a higher upright of the railing section and a curved part, wherein the last string of the section passes by a curved part to a lower height upright is characterized in that the railing section consists of two half-sections: upper and lower one, the upper and lower uprights of which are perpendicular to the stair carriage, the handrail and the strings are parallel to the stair carriage, wherein the intermediate parts between the rails and the odd string, even and odd strings are vertical and the intermediate parts between the odd and even strings are perpendicular to the stair carriage, wherein the sequence of the intermediate parts is indicated from top to bottom, from the railing to the stair carriage, the upper and lower half-sections are turned in opposite directions so that the upper and lower uprights of the upper and lower half-sections are adjacent to each other and are connected to each other by a plug or fixed connection.

EFFECT: technical result consists in ensured security.

Description

The invention relates to the field of technology, where fences of flights of stairs, inclined paths, ladder rails are used.

Known technical solution "Section of the fence" (positive decision on the application 2019113265/03 (025616), "Section of the fence"), which can be used to fence horizontal platforms and routes of personnel, pedestrians.

The disadvantage of this design is that when using it on flights of stairs, a gap is formed between the rails on the horizontal section of the route or platform and on the march. This does not meet safety requirements.

The objective of the invention is to ensure safety when applying the design principles adopted in the decision "Section of the fence" (positive decision on the application 2019113265/03 (025616), "Section of the fence"), for the implementation of side fences or inclined paths.

The specified technical result is achieved by the use of a section of the fence, which includes posts of higher and lower heights, handrails, odd strings and even strings, and made of a single lash of high-quality rolled metal, and the post of greater height in its upper part passes into the handrail in a curved section, which in succession pass into odd and even strings, while the odd strings are deployed towards the rack of a greater height, and the even ones are from it, the odd strings are connected to the railing by a sequentially curved, intermediate part connected to the rack of a greater height of the adjacent section, and a curved part, and even strings are connected to an odd string by a sequentially curved part, an intermediate part connected to a post of a larger height of the fence section, and a curved part, while the last string of the section passes the curved part into a post of a lower height, characterized in that the fence section consists of two half-sections: upper and lower -, racks of greater height and a lower height, which are perpendicular to the kosour of the staircase, the railings and strings are parallel to the kosour of the staircase, and the intermediate parts between the railings and the odd string, the even and odd strings are vertical, and the intermediate parts between the odd and even strings are made perpendicular to the kosour, and the sequence of placing the intermediate parts are indicated from top to bottom, from the railing to the stringer, the upper and lower half-sections are deployed in opposite directions so that the racks of a greater height of the upper and lower half-sections adjoin each other and are connected to each other by a detachable or permanent connection.

The figure shows the design of the proposed fence.

The section of the fence, which includes racks of higher and lower heights, railings, odd strings and even strings, and is made of a single lash of high-quality rolled metal, and the rack of a greater height in its upper part with a curved section passes into the railings, which successively turn into odd and even strings , while the odd strings are turned towards the rack of a greater height, and the even ones are from it, the odd strings are connected to the railing by a sequentially curved, intermediate part connected to the rack of a greater height of the adjacent section and a curved part, and even strings are connected to the odd string by a sequentially curved part , with an intermediate part connected to a post of a greater height of the fence section and a curved part, while the last string of the section passes with a curved part into a post of a lower height, characterized in that the fence section consists of two half sections: upper 1 and lower 2-, posts of greater height 3 and less heights 4 of which are perpendicular to the stringer 5 l staircase 6, railings 7 and odd 8 and even strings 9 are parallel to kosour 5 of staircase 6, and the intermediate parts 10 between the railings 7 and the odd string 8, even 9 and odd 8 strings are vertical, and the intermediate parts 11 between odd 8 and even 9 strings are made perpendicular to the stringer 5, and the sequence of the placement of the intermediate parts 10 and 11 is indicated from top to bottom, from the railing 7 to the stringer 5, the upper 1 and lower 2 half-sections are deployed in opposite directions so that the racks of greater height 3 of the upper 1 and lower 2 half-sections are adjacent to each other and connected to each other by detachable or permanent connection.

As shown in the figure, half-sections 1 and 2 of the barriers are made by plastic deformation of a single lash of long products. In this way, racks, railings, strings are formed. This minimizes manufacturing costs, since typical operations for the manufacture of such fences include welding, marking of parts for welding, post-welding operations, and coating.

Comparison of the prototype device and the claimed device shows that the declared section of the staircase fence obtained by plastic deformation allows using the concept of the prototype to obtain a safe solution for stair flights or inclined paths of movement.
