FIELD: construction.
SUBSTANCE: invention relates to construction and can be used in the erection of coatings of buildings and structures, in which load-bearing elements are made of lattice structures. Purpose of the invention is to increase the strength of fastening elements of the lattice elements from closed profiles made of pultrusion fiberglass. Purpose of the invention is achieved by that in a known lattice structure comprising belts of open-ended paired elements, in whose cavities the ends of the lattice of the closed profiles are inserted and fixed, the lattice closed profiles are made of pultrusion fiberglass with opposite flat walls adjacent to the walls of the belts of paired elements of greater thickness than the others and are tightened by through bolts with paired elements of the belts. It is recommended to perform the lattice structure with the belts made of paired fiberglass plated channels made by the pultrusion method.
EFFECT: invention makes it possible to increase the strength of the lattice rods fastening elements by from one and a half to two times.
