Formwork ROBUD STAYER is used for cast-in-place construction for the erection of walls, columns, crossbars, foundations of buildings and structures.
ROBUD STAYER is distinguished by its high universality (the presence of special holes in the anchor profile) and a convenient modular grid. All panels are connected under 90° angle and in line. Therefore, any element in set can be used to form columns of variable cross-section, outer corners and end walls, foundations and crossbars. Due to this, we get an easy adaptation of the existing formwork kit for any configuration of the cast-in-place construction.
A small specific weight of the set (45-50 kg / m2) allows the use of tower cranes with lower carrying capacity. In case it's impossible to use a tower crane, the weight of the elements allows in some cases to be mounted manually. Due to the use of ZRK straightening couplers, there is no need to install additional combination plates at all joints, which significantly reduces the time to assemble formwork.
Buying construction equipment, many specialists often compare it only by the initial price. Often, additional costs for materials, labor, for quick wear and restoration of formwork components are not taken into account. The universal STAYER system ensures high speed of construction and allows you to significantly save consumables and labor. Considering the long service life, we get a multiple return on investment.

Usage of ROBUD STAYER allows you to reduce volume and range of formwork inventory due to universal elements of the system. Any STAYER wall element is easily adaptable to form columns, outer corners and end walls. For this, it is enough to drill holes in plywood.
For the manufacture of the supporting frame of the ROBUD STAYER elements, German metal profiles made of special steel are used, providing precise geometry, high strength, light weight and durability of the structure.
STAYER elements are equipped with convenient handles for maintenance, workers less use tools, are less tired, it increases safety and productivity.
Covering the frame of the element with hot zinc provides long-term protection against corrosion. The thickness of the coating with zinc is 60 - 80 microns. During the entire period of operation of the panel, expensive repair painting is not required. The frame of the element does not rust from the inside and outside, retaining the original strength characteristics and aesthetic appearance for a long period.
To protect the end of the plywood from moisture the wedge gap that is formed by the collar and the plywood edge, is filled with sealant.
Steel Bushings in the frame profile have conical shape and are designed to tie elements with anchors. Such shape allows joining the panels at an angle or up to 3.5 ° offset. The concrete which gets accidentally to the bushings can more easily be removed from the conical bushings.
Sole in the system ZRK multifunctional coupler connects and aligns panels in a line, connects at an angle of 90⁰, allows you to install compensating inserts from 0 to 10 cm between the panels. A rigid coupler design ensures reliable connection of the elements among themselves without additional combination plates and crossbars. The forged wedge and tooth rack of the coupler made of solid steel will ensure its continued operation.

By installing ROBUD stripping corners in the internal formwork of the elevator shaft, in staircase or in "U" - shaped assembly, you can mount it in one lift. Easy angle control reduces labor costs, shortens installation time.
Two ROBUD stripping corners are mounted on the inner part of elevator shaft diagonally. Before concreting the corner is installed to standing position by turning the spanner. The sides of the angle in this position will make 25 cm.
After concreting and concrete setting, the span is turned to the opposite direction of 180 °, sides of the angle come inside for 1,5 cm each thus reducing the size of each side of the formwork rectangle.
Formwork tears of the concrete and can be extracted by the crane without dismantling by one piece.
Such design is proved on practice to be easy, reliable and convenient in use.
We pay great attention to the designing of parts, and quality of materials, which are used for the manufacture of ROBUD FORMWORK, and guarantee safe and flawless functioning of our equipment under any climate conditions. Panels, lifting parts and fastening accessories are tested on special stands. As a confirmation of ROBUD formwork quality is being its successful use under extreme conditions of different parts of our planet – from severe Siberia to African continent.
Safe work is an important component of every construction project and nothing can be more valuable than human life and health. Due to this we are working hard to make work with our formwork maximally safe. Service bracket are created for this aim.
Working decking and handrails should be laid on service bracket for safe concreting.
