GLASS BLOCK FOR WINDOWS Russian patent published in 2001 - IPC

FIELD: construction engineering; construction of glass blocks. SUBSTANCE: glass block has at least two sheets of window glass joined over perimeter to form enclosed space and dielectric spacing members setting distance between window glass sheets. Mating surface between each spacing member and window glass sheets as well as distance between spacing members are found from equation 0.0002<S/1<0.001, where S is mating surface area between spacing member and window glass sheets surface, mm², l is distance between spacing members, mm. EFFECT: improved mechanical strength of glass block. 4 cl, 2 dwg, 2 ex
