ある。The present invention forms a plurality of nut insertion recesses 9 that open at the upper ends of the outer protective bodies 2 of a plurality of chimney units) 3a, 3b, 3C, etc. stacked vertically on a foundation 4, so that the plurality of nuts can be inserted into A plurality of insertion holes 8 which are open at the bottom 10 of the insertion recess 9 and have a smaller diameter than the inner diameter of the nut insertion recess 9 are formed through the outer protection body 2, and a plurality of foundation nuts 5 are fixed to the foundation 4. Then, insert a plurality of bolt rods 7 with upper end nuts 6 fixed to their upper ends into the plurality of insertion holes 8 of the lowest chimney unit t-3a, and insert the plurality of bolt rods 7 into the plurality of base nuts 5. The lower surface of the upper end nut 6 is pressed into contact with the bottom part 10 of the plurality of nut insertion recesses 9, the lower surface of the lowest chimney unit 1-3a is pressed against the foundation 4, and the upper chimney unit 1-3b, 3C is screwed into place. ... in the plurality of insertion holes 8,
A plurality of bolt rods 7 having upper end nuts 6 fixed to their upper ends are inserted, the plurality of bolt rods 7 are screwed into adjacent lower upper end nuts 6, and the lower surfaces of the plurality of upper upper end nuts 6 are inserted into the plurality of nuts. The chimney is in pressure contact with the bottom 10 of the recess 9, and the lower surface of the upper chimney unit 3b, 3C... is pressed against the upper surface of the adjacent lower chimney unit 3a, 3b..., so assembly is easy. In addition, the outer protective body 2 has a high strength and is safe for receiving compressive force, and there is no protrusion such as a support frame on the outside, so it has a good appearance and can withstand long-term use. chimney units) 3a, 3
The metal fittings that connect b, 3C, and so on are an upper nut 6 and a bolt rod 7, and can be assembled and disassembled with simple operations.
