zsaluzat

In Hungarian construction terminology, zsaluzat refers to formwork: a temporary mould used to shape concrete as it is poured to form structural elements such as walls, slabs, beams, and columns. It supports loads during placement and curing and defines the surface finish. Once the concrete attains sufficient strength, the formwork is removed.

Formwork is made from various materials. Timber and plywood are common for traditional schemes, while modular systems use reusable panels and props. Steel, aluminum, and plastic formwork offer higher durability and speed. Stay-in-place forms combine the mould with permanent components, and fabric or sliding formwork is used for special applications, such as large-surface slabs or high-rise cores.

Design and construction considerations: formwork must resist fluid concrete pressure, maintain alignment and smooth surfaces, and accommodate openings for reinforcement. It requires proper release agents to facilitate stripping, accurate measurement to ensure dimensional tolerances, and safe temporary supports. Erection sequencing and curing conditions affect final quality.

Modern formwork systems aim to increase productivity and reduce waste through modular, reusable components and standardized sizes. Selection depends on factors such as element geometry, pour height, repetition, cost, and site constraints. Proper inspection and safety protocols are essential to prevent accidents during erection and removal.
