PROBLEM TO BE SOLVED: To bring the same effect as face joint with a ridge beam, fasten right and left rafters with the same bracket at the same time and ensure efficient construction by providing lower flat portions and rising portions at the right and left sides via a right and left connection without using a cogging cut at a rafter ridge. ;SOLUTION: Lower flat portions 2, 3 are provided at the right and left sides via a right and left connection 1 and rising portions 4, 5 and rising portions 6, 7 are provided in series before and behind them. In a 2×4 technique, the right and left connection 1 is fixed to a ridge beam with two-point nailing and right and left rafters are placed on the right and left lower flat portions 2, 3 to drive two nails each in the rising portion 4, 6 and 5, 7 before and behind them. In this case, the rising portions 6, 7 are 40 mm higher than the rising portions 4, 5 so that the lower flat portions can be bent in use corresponding to the width of the rafters, when in two combination. Folds are previously marked at contacts between the right and left connection 1 and each of the lower flat portions 2, 3 for easy bending to a gradient.;COPYRIGHT: (C)1999,JPO
