(2) The fixture 3' and a clamp 2 are installed on the floor 6 above the through hole filled up with the refractory filler 5 and a fireproof box is put on the floor so that the fixture 3' and clamp 2 can be housed in the box, and then, the box is filled with a refractory filler. (3) For a fireproof cable with suspension wires, the support fixture and cable clamp are attached to a frame in the through hole and a fireproof cable and a messenger wire are collectively supported with the clamp.</p> |
