Inclined (diagonal) prop - use
Inclined, diagonal props – why are they so important?
Inclined, diagonal props are a basic element of temporary securing for prefabricated walls, columns, and wall formwork on construction sites. Proper selection and installation of props directly impacts the safety of people on the site as well as the quality and geometry of the erected structure.
What are PXL335 diagonal props?
The PXL335 diagonal prop was designed to stiffen and precisely adjust the position of prefabricated walls, columns, and formwork. It is a steel, telescopic adjustable prop weighing approx. 14.2 kg, combining support function with the ability to accurately set the vertical alignment of elements.
The PXL335 prop operates in a length range from approx. 2.17 m to 3.35 m, allowing it to handle typical heights of prefabricated wall elements in multi-story residential construction. Thanks to this, one prop can be used across different projects, reducing the number of equipment types needed in storage.
Construction and adjustment of the PXL335 diagonal prop
The PXL335 prop has a telescopic construction consisting of an outer and inner profile, enabling two-stage length adjustment.
- The first stage of adjustment is telescopic: by sliding the inner profile within the outer one to achieve the rough length, then securing the position with the PXL335 screw and pin in the appropriate holes.
- The second stage of adjustment is performed using adjustment spindles (Roman screws) with protected threads at both ends of the prop, allowing precise length and wall verticality setting.
Before using the spindles, they should be extended to approximately the same length on both sides to enable safe utilization of the full adjustment range without risking damage to the prop. The outer profile has one ø14 adjustment hole, while the inner profile has eleven holes spaced every 10 cm; the inspection holes at the ends of the profiles are solely for weld quality checks and cannot be used as adjustment holes.
Adjustment range and permissible loads of PXL335
A key parameter from a safety perspective is the permissible load of the prop across its full adjustment range./
For the PXL335 diagonal prop, maximum permissible loads are:
- Range 2.10–2.84 m – permissible load 13.5 kN
- Length 2.95 m – permissible load 12.8 kN
- Length 3.05 m – permissible load 12.1 kN
- Length 3.15 m – permissible load 11.4 kN
- Length 3.25 m – permissible load 10.7 kN
- Length 3.35 m – permissible load 10.0 kN
It is not permissible to load PXL335 props beyond the values specified in the documentation, as this may lead to permanent deformations or support system failure. Load capacity information should be considered already at the prefabricated element installation design stage and when planning the number of props per element.
Installation of PXL335 diagonal prop: angles, anchoring, connections
The effectiveness and safety of the PXL335 prop's operation depend on proper installation.
- The upper foot of the prop is attached to the prefabricated element (e.g., wall) via the ø17 hole using an appropriate system bolt/anchor.
- The lower foot of the prop is anchored to load-bearing, solid concrete (slab, foundation) also through the ø17 hole, using appropriate mechanical or chemical anchors selected for the concrete class.
- The angle between the prop and the substrate should be within the 45–60° range, which ensures favorable force transfer and stable operation of the diagonal prop.
The heads at both ends of the prop are secured with M8x16 screws and spring washers, while the plate-to-spindle connections are made with B12x40 screws secured by 3.2×20 split pins. Before each use, check the completeness of these elements and the proper tightness of the connections.
Technical condition inspection and safety rules
The PXL335 usage instructions require that each prop be inspected on site before every use for technical condition and proper operation.
In practice, this means the need for:
- checking straightness of profiles, absence of cracks and deformations,
- checking the threads of the spindles and their smooth operation,
- verification of the set of bolts, cotter pins, spring washers, and proper tightening.
- not allowing the use of props that are missing elements or show visible damage.
Using PXL335 props in a manner inconsistent with the instructions, exceeding permissible loads, or omitting required anchors and installation angles is prohibited and may lead to serious hazards on the construction site.
