Prefabricated engineering structures and a method for installing prefabricated engineering structures

Abstract

Prefabricated engineering structures include at least one rail with a C-shaped, partially closed cross-section, permanently mounted to the wall, which is screwed to the wall surface or to a groove made in the wall, preferably so that the front, partially open surface of the rail is flush with the wall surface, and on the rail or inside its profile, there are side walls of the structure with upper and lower plates placed between the side walls of the module, which are connected to the side walls of the structure by connectors cooperating with metric sleeves placed in the side walls of the structure and the upper and lower plates, each side wall, at the rear edge in contact with the wall, has sockets in which locks are placed, the shape of the locks corresponds to the shape of the sockets, wherein the wheel located in the through hole of the socket is cut so thatthat its secant perpendicular to the axis passing through the centres of both wheels forming the shape of the lock is distant from the axis of the through hole of the socket by 9.5 mm ± 9.5 mm, in the extreme side walls of the bodies, i.e. side walls mounted at the ends of at least one rail with a C-shaped, partially closed cross-section, locks with a cuboid hole with one side chamfered or rounded are mounted, in the inner side walls of the bodies, i.e. walls located between the extreme side walls of the bodies, locks are mounted. A method of assembling prefabricated engineering structures, which is characterized in that after checking with a template and possibly leveling the ground plane, at least one rail with a C-shaped, partially closed shape is permanently mounted on the wall or in the wall surface at the interior finishing stage so that the distance of the rail axis from the ground is 70 cm ± 20 cm in the case of lower modules and 200 cm ± 20 cm in the case of upper modules,then a template is inserted into a partially closed C-shaped rail in order to check the accuracy of the visible contact points between the structures and the walls, then the side walls of the structure are inserted into the partially closed C-shaped rail so that a prefabricated lock connector is inserted into the rail, while in the case of the outermost forms, locks with a cuboid opening are used into which a closed rectangular profile is inserted and its movement is blocked by expanding the screw placed in it against the rear shelf of the at least partially closed C-shaped rail, in the next step the side walls are connected with their backs or strips, by inserting the connectors placed in the metric sleeves, and also by inserting the top and bottom boards into the metric sleeves, these operations can be carried out interchangeably, then the covers and strips are installed together with accessories, in particular shelves, inserts, drainers, drawers, and then the door.,
