<p>PURPOSE:To improve positioning accuracy by arranging two junction boards on a panel body, extending a rectangular board and a dampproofing sheet at a frontage of a frame member to form the panel body, stacking the junction boards on the rectangular board and the dampproofing sheet, and providing one of the junction boards in the lateral direction of the panel body while the other junction board in the opposite direction, respectively displaced. CONSTITUTION:Two junction boards 40 and 42 are extended on a panel body 1A to constitute a roof truss panel 1A. Then, a rectangular plywood 20 is extended on one of frontages of a frame 10, while a dampproofing sheet 30 is extended on the other to constitute the panel body 1A. Next, the junction board 40 is moved in parallel in the lateral direction of the rectangular plywood 20, and a junction projection 40a and a junction recess 40b are formed. The junction board 42 is displaced in parallel in the opposite direction, and a junction recess 42 b and a junction projection 42a are formed.</p> |
