Wooden planks of 10x10 sizes are fixed together in a special place of construction site in strict compliance with dimensions, given in H20 wall formwork project ( considering the intervals between SRZ walers).
SRZ walers are placed at one and the same level and fixed on wooden planks as shown in the picture.
YH20 beams of the same dimensions as given in the project are placed on SRZ walers. However, the appropriate distances between the elements are to be strictly observed.
As seen at the picture above, H20 beams and SRZ walers are connected with contersunk screws through H20 strap connection placed at the edge of SRZ straps.
All the rest of H20 beams are connected to SRZ walers in a same way as described above and the distances between the elements are checked.
When H20 beams are fixed, plywood with the thickness required by the project is attached to the H20 with countersunk bolts.
In a same way wall panels are carefully prepared according to the measurements given in the project.
DRZ (vertical walers) are connected to SRZ ( steel walers) by means of M16x40 bolts as seen in the picture.
The consoles situated under the DRZ are attacched by the adjustment roller mechanism to the consoles of hydrolic wall formwork (these consoles are different from the consoles of climbing wall formwork mounted by crane). This adjustment roller mechanism is especially produced to facilitate the movements of the formworks.
Lower and upper supports are connected between the SRZ walers and consoles by means of bolts.
Three lines of H20 beams in sizes given in the project, are connected to the bottom part of the console (as seen in the picture) with lag screws.
Wooden planks prepared in suitable lengths of 5x20 sizes are attached to them with lag screws.
The console railing is attached to the edge of the console with M14x80mm bolts. Railing planks of 5x20 are fixed on the railing with lag screws.
When formwork panel and working platforms are prepared, the rail mechanism (NTR) is adjusted to the form as shown in the picture above.
After the prepared formwork has been installed on the climbing rail mechanism, the first working platform, on which hydraulic system is checked and the concrete pouring process is controlled, is fixed (in size given in montage project) on the form.
The second working platform is installed on the climbing rail mechanism just as previous one. It is used for removing the hanger system of NTR (climbing rail), waal conic and making the last adjustments.
The hydraulic pistons, used for lifting of the system are adjusted to the formwork in the places indicated in the montage project. Then, the formwork module, prepared in the way described, is ready for use.
Suspension brackets for elevating rail mechanism are attached to the panel, undergone 2 stages of concreting by means of hydraulic system.
Single-sided hydraulic formwork, prepared on the platform before, is suspended on these hangers.
The described process is repeated for all the formworks. They are suspended to the hangers in the fixing places on the climbing rail platform.
The same processes are repeated for all the formworks of the others directions. After the installation has been completed, the process of concreting begins.
After concrete setting, forms are being opened and lifted by means of the hydraulic system. The bottom working platform is fixed as shown in the picture above. The formwork is ready for the further use.
