Three types of structures can be distinguished in multi-storey buildings made of prefabricated elements:
b) plate (large-plate),
c) mixed; block-skeletal or plate-skeletal.
One-story high and wide wall blocks are used to make a block structure 90, 120, 150 i 180 cm and the length of the floor slabs 240-600 cm and width 60-180 cm. The length and width of the plates 1 changes what 30 cm. Figure a shows a diagram of a block structure with a transverse arrangement of load-bearing walls, and to the line. b with a longitudinal arrangement.
Schemes of slab structures with a longitudinal and transverse arrangement of bearing walls are shown in Fig. c, d. The floor slabs can rest on two, three or four walls (Lynx. e, i). Wall shields are made : made of slabs one story high and half or the entire width of the building wide. Floor slabs can be made with the width of the slabs used in buildings with a block structure, or dimensions corresponding to the horizontal dimensions of the room to be covered.
The mixed wall and column structure with a longitudinal arrangement of load-bearing walls is shown in Fig. g, while in fig. h shows the wall and frame system with a transverse arrangement of load-bearing walls. Mixed regimes are usually used there, where there is a need for larger rooms. A smaller number of walls allows you to introduce changes in the design of rooms for various purposes.
