PURPOSE: To improve the construction property of a fireproof covering and a fire stop and improve a fire spread prevention function while ensuring sufficient fireproof performance of joint parts such as walls, floors, ceilings, etc., on upper and lower stories in a building which is built mainly by wooden panels. CONSTITUTION: A floor panel P3 is arranged and joined between a wall panel P1 on a lower story and a wall panel P2 on an upper story which are to be joined vertically each other, and this structure is applied to a building in which fireproof coverings B1, B2, B3 are provided for each wall panel P1, P2 and the floor panel P3. Each wall panel P1, P2 includes a frame which surrounds the circumference and face members 21, 22 attached on front and rear surfaces of the frame, and a horizontal muntin 15 which partitions an inner space of the frame into upper and lower sections is arranged. This horizontal muntin 15 functions as a fire stop in the inside of the wall panel. |
