PROBLEM TO BE SOLVED: To provide a hollow integration rod combination structure which is assembled with a fitting structure, has the joint strength enhanced, also has the heat resistance improved, requires a shorter time for assembling, and improves production efficiency. SOLUTION: The hollow integration rod combination structure comprises four plates (51), and each plate 51 has a front end (55) and a rear end (56), and at least one projecting part (57) is provided in the front end (55), and at least one recessed part (58) to be fitted to the projecting part (57) is provided in a position corresponding to the projecting part (57), of the rear end (56), and the plates are coupled with each other so that projecting parts (57) of one plate may be fitted to recessed parts (58) of adjacent plates, and thus a hollow integration rod (5) is formed.
