From the PERI UP system elements, stairs and stair towers for the public area can be created. Easy-to-use, wide staircases are suitable for large crowds. With its safety guardrails and multiple handrails, this kind of stairs is suitable for people of all ages. PERI UP EASY and PERI UP FLEX can be combined with one another and so there are hardly any limits to their fields of application.
Also access to construction sites and for industry can be achieved with the systems.
In addition to the special connection technology, PERI UP scaffolding technology offers consistent metric grid dimensions: all PERI UP system components such as standards, ledgers and decks are available in length grid arrangements of 25 cm or 50 cm. The system and decking widths also take into consideration the metre as a base unit.
PERI UP Flex usually uses 25-cm-wide steel decks with lengths from 50 cm to 300 cm for all applications from shoring over different types of work scaffolds to access solutions. PERI UP Easy Frame is available as façade scaffolding with system widths of 67 cm and 100 cm; depending on the width, both combi decks with a width of 67 cm as well as steel decks with widths of 33 cm or 25 cm can be used.
Since also the height dimensions of PERI UP Flex and PERI UP Easy are identical, the possibilities for combining them both also horizontally are almost unlimited.
With PERI UP scaffolding technology, a minimum number of system components can be used to realize a previously not feasible range of applications. Rosett nodes are integrated on the vertical system components onto which horizontal components can be directly connected without requiring any couplers. This connection technology is not only fast and safe, it also underlines the boundaries between frame and modular scaffolding.
The connection on the PERI UP Ledger is in the form of a wedge which is hooked into the rosette opening. Thereby, the securing wedge drops into the rosette opening due to its own weight and locks automatically. The wedge is then secured in position with one blow of a hammer.
All PERI UP decks have integrated protection against lifting (Locking Deck): the clamp on the deck engages the rectangular ledger without requiring any additional measures. PERI UP decks are thus secured in position after installation without additional components as well as being secured against lifting. If required, individual decks can be subsequently removed, e.g. for bringing in materials.
Ledgers can be directly connected to the rosette nodes of the PERI UP Standards as well as the PERI UP Easy Frame. Thereby, for example, PERI UP Flex Stairs with 75 cm widths can be connected to the frame scaffolding without any additional frame columns or couplers. The transition from the stairs to the scaffold bay is covered without leaving any gaps, therefore no gap covering is required.
Through the integrated scaffold node on the Easy Frame, PERI UP Easy can be combined with PERI UP Flex Modular Scaffolding. Thus, for example, brackets as well as ledgers for the erection of prefabricated stairs can be quickly connected without requiring any accessories.
For stairs used in public areas, special attention is paid for ensuring the safety of the users. For stairs used in public areas, special attention is paid to providing complete safety for the users. Existing regulations are frequently tightened through additional requirements. PERI UP Rosett Stair Public corresponds to all the latest requirements and is used to realize a wide range of structures using very few individual components.
PERI UP Rosett Stair Public has been designed for live loads of up to 7.5 kN/m², and the guardrails for loads of up to 2.0 kN/m meet the highest Single width continuous staircase 250 cm wide. The landings are installed after 18 steps. safety requirements. In addition, geometrical requirements regarding the rise/tread ratio, safety barriers and climbing over guardrails are fulfilled as well as being vandalism-proof to a very high level.
The system has been optimized for use with public stairs thanks to landings completely covered with decking. The decks are completely closed and protect workers on all levels against dirt and water falling from higher levels.
Typical applications are as access to grandstands, to temporary pedestrian bridges or as a replacement for indoor and outdoor stairs during refurbishment.
With the stair stringers of the PERI UP Rosett Staircase Public, steel decks can be installed on the left and right of the stringers. In doing so, any required width for the bank of continuous staircases can be assembled whereby the width of each individual flight of stairs can be freely chosen.
150 cm, 200 cm and 250 cm widths are available which fulfil the clear minimum width requirements of 120 cm, 180 cm or 240 cm for public stairs in each case. The flights of stairs provide safe accessibility due to guardrails on both sides and separate large crowds into smaller and manageable groups.
The directions can be specified thus contributing to very effective use of the stairs by large crowds of people, e.g. at trade fairs.
On every 150 cm wide landing, the direction of the staircase can be changed by 90° or 180°. This results in dog-legged staircases which are used, for example, for accessing stages with entrances and exits on both sides.
The transition between two guardrails is realised by means of guardrail connectors which are arranged in a straight line or over the corner into which a guardrail filler can also be installed.
Stair towers with PERI UP Rosett Stair Public can be adapted to existing ground plans. This results in minimum dimensions of 3.25 m x 5.50 m.
Depending upon customer requirements and structural conditions – and on the basis of the minimum dimensions – other geometries can be selected for the stair tower by changing the lengths of the staircase units. In this way, stair towers are formed around a stair well. For standard live loads, stair towers can be erected up to heights of 24 m. Depending on the country and application, live loads range between 3.5 kN/m² and 7.5 kN/m².
