MOBILE PREFABRICATED MODULAR STRUCTURE Russian patent published in 2002 - IPC

FIELD: construction engineering, particularly, mobile prefabricated modular structures. SUBSTANCE: mobile prefabricated modular structure has net of columns, vertical beams and connected with them habitable or utility modules. Net is formed by columns. Each column is made of four interconnected angles forming column shape in cross-section. Upper and lower bases of each column present four interconnected n-arm base members where 2≤n≤4. Arms of base members are formed by lengths of angle each directed along end of four semi-axes a, b, c1 and c2 outgoing from one point o and located in space so that c1 and c2 form straight line, and a and b are perpendicular to said straight line and to each other. In this case, all arms of base member are interconnected by ends directed to point o. Length of base member arms may be equal to one another and may not be equal to one another and satisfy the condition: Li= Ii+di, where i may assume values a, b, c1 and c2; Li is length of arm of i-base member in one of direction of coordinate axes a, b, c1, c2; Ii is main size of i-arm equal to length of arm section adjacent to respective arm of neighboring base member; di is additional size of i-arm equalling to the length of section of arm adjacent to horizontal section of beam or vertical column section joined with said arm of neighboring base member oriented in the same direction of arm. In case of absence of arm in base member in some axis Li=0; in other case, Li > 0, in this case Ii ≥ p and di=0, or di ≥ k, where p and k are constants calculated on base of provision of required strength of joint depending on type-size of angle. Said modular structures may be used in erection of low buildings of public, cultural and community applications. EFFECT: improved technological effectiveness of structure assembly and higher structure strength. 4 cl, 10 dwg
