PROBLEM TO BE SOLVED: To provide a clamp device giving structural completeness to T-boxes in a boiling water reactor pressure vessel and firmly holding welded seams when one or more deposition sections are broken. SOLUTION: This T-box clamp device is clamped to T-boxes 26, 30 and distribution header pipes 18, 20 to keep a distribution header at the prescribed position in contact with the T-boxes 26, 30. The T-box clamp device includes first and second clamp assemblies and a clamp strongback assembly connected to the first and second clamp assemblies. Each clamp assembly includes upper and lower clamp main bodies connected to the distribution header pipes 18, 20. The strongback assembly includes upper and lower strong back main bodies coupled with the T-boxes 26, 30, the upper strongback main body is connected to first and second upper strongback main bodies, and the lower strongback main body is connected to the lower clamp main bodies of the first and second clamp assemblies.
