Experience in manufacturing and installation of prefabricated wall panels on the construction site for rural and cottage construction

Abstract

The technology of manufacturing wall panels in a permanent form work, on the construction site, with their further rise to the design position. The technology was developed for individual houses. The first experience of its use in Lenin sky district of Moscow region is described. After the foundation was made and the floor was installed, the permanent form work was installed along the outer walls in the form of a thin-walled bent channel 160 mm high with a wall of 4 mm. In this channel fit the reinforcing grid was laid and reinforcement around window and door openings of a wall was carried out. A mesh of 200*200*5 mm was used, and reinforcement A-IV, 10-12 mm, was used to reinforce the structure. After pouring and setting the concrete, the wall was raised using jacks along special guide rails and temporarily fixed. As the installation of all enclosing walls, they are rigidly connected to each other. Two people worked at the construction site. The total time of construction of the above-ground part was three months. Based on the work carried out, it was concluded that the technology has a practical application, but requires more detailed elaboration of the panel design and the development of a safe lifting mechanism.
