    • PROBLEM TO BE SOLVED: To prevent collapse of an architectural structure by withstanding horizontal forces generated owing to earthquakes or strong wind even during construction by the jack-up method. SOLUTION: A resistant device 3 against horizontal forces is installed between a horizontal material 1 at the upper floor and a horizontal material 2 at the lower floor. The resistant device 3 against horizontal forces is constituted of a reinforcing diagonal material 6 provided with an extensible joint 5 fixed with a pin to the horizontal material 1 of the upper floor at one end thereof and fixed to the horizontal material 2 of the lower floor at the other end. The joint 5 is extended in accordance with the movement of lifting-up jacks 4. Since the joint 5 is constituted so as to bring out such a resisting function that it follows up the tensile strength of the reinforcing diagonal material 6 but it does not contract against the compression force, even if a horizontal force acts on an architectural structure while constructing it by use of the jack-up method, this device withstands the force so that the structure does not collapse.
