Abstract

PROBLEM TO BE SOLVED: To contrive simplification of an initial work process and its further speed up by providing a pivot base part on both sides of the top in the crosswise direction and opening and closing a fastening board and a clamp fixing member with a handle lever and bending the ends of adjacent building boars and connecting each other. SOLUTION: A connection member is loaded on opposed connection pieces of adjacent building boards provided side by side on a substrate where a fastener is laid out on the connection member and expanded by turning handle levers 6. The expansion of the connection member brings a pair of fastening boards 5 to approach each other so that they may operate in the closing direction, thereby hitting the tip of the fastening boards 5 against both winding areas of the connection member and bending inwardly each of the winding areas. When both fastening boards 5 approach each other, the handle levers 6 are further expanded so that the fastening boards 5 may bend the winding areas horizontally. The bottoms 8c of clamp fixing members 8 are loaded on the main board of a building board, thereby executing clamping work in an initial stage process. After the clamping work, a motor-driven fastening machine is used to mold the tops of the connection pieces and connection members on both sides in the crosswise direction into downward and inclined shapes.
