CONNECTING STRUCTURE OF LINING SLAB

PURPOSE: To make each lining block not jolt by the way of forming it into a triangle as well as to connect apexes of plural triangular lining slabs unseparably. CONSTITUTION: Each of connective fittings 4 with a through hole 3 each is projected from each top face of triangular lining slabs 1 cut with each apex and clamped tight, while each apex of a lot of triangular lining blocks 1 is mounted on a support beams 5 in putting them in order, forming a hexagonal opening part 6 by respective top faces 2 of six triangular blocks 1. Each top face of two connective fittings 4 is set up on the same surface, and a support plate 7 clamped with six connecting longitudinal shafts 8 at a lower part around this hexagonal support plate 7 in response to the through hole 3 of the connective fittings 4 and the six connecting longitudinal shafts 8 are inserted into the through holes 3 of the connective fittings 4 and then they are all mounted on these connecting fittings 4, while a cold setting low strength filler 9 is filled up in an upper part of the support plate 7 inserted into the hexagonal opening part 6, whereby connecting these lining blocks together.
