The grooves are made with cylindrical openings for the outer diameter of the cylindrical body of the connecting element, and the other blocks are mated with the first ones and made as a rectangular parallelepiped with studs made on the four faces of the parallelepiped. The studs are made with cylindrical openings for the outer diameter of the cylindrical body of the connecting element. The surfaces of the grooves and studs are equidistant, congruent and equidimensional, and are united into the block prefabricated structure by means of the connecting elements.

EFFECT: reducing the shelter erection time due to equipping the frame with a closed block structure.
