Claim 1

In a combustion chamber of a gas turbine powerplant having a double wall structure formed by a separate combustor shell and at least one floatwall panel, an attachment arrangement comprising: (a) means on said panel protruding therefrom and through said shell; (b) means interengaging said protruding means on one side of said shell opposite to the other side thereof which faces said panel; (c) said protruding means including a pair of hook-like projections each of which has an outer portion spaced from said one side of said shell and extending generally parallel thereto, said outer portions also extending in generally parallel relationship to one another and in generally opposite directions; (d) said interengaging means including a pair of thin plates each of which is tapered in cross section, points in opposite directions toward one another and is disposed in forced-fitted, wedged condition between each said outer portions of said respective hook-like projections and said one side of combustor shell, said thin plates being further disposed in upside-down relation to one another in their respective wedged conditions and being rigidly connected together so as to oppose movement of one another away from their respective wedged conditions and thereby retain said panel in a desired predetermined position adjacent to said shell; and (e) means rigidly connecting said plates of said pair thereof to said shell.
