PROBLEM TO BE SOLVED: To attain earthquake-resistant reinforcement at a low cost by a method wherein the periphery of a building is surrounded by poles, in which lower sections are buried into a ground and which are disposed upright, and a plurality of the poles are attached, increasing the intervals of the poles on the outer circumference of the wooden building and the poles and the building are clamped at second floor positions. SOLUTION: Poles 2 such as steel pipes disposed upright on the outer circumferential section of the existing two-storied wooden building 1 are installed, enclosing the periphery of the building 1. Reinforcements 3 such as base reinforcements, vertical reinforcements, horizontal reinforcements or the like are arranged and driven into a drilled hole in a ground, and foot protection bodies 4 composed of reinforced concrete are formed at that time. The bodies 4 are connected to a foundation such as a continuous footing 5, a sill 6 or the like as required. The ground height of the poles 2 is set in the same extent as the first floor section 1a, and oblong plates 8 are installed near the tops of the poles and bonded with existing wooden girths 10 by a bonding material or the like at the level of the second floor 9 of the building 1. Angle material-borne flanges are formed in caps 11 at the tops of the poles 2, and the infiltration of rainwater is prevented. Accordingly, earthquake-resistant reinforcement can be obtained simply in a short period at a low cost only by mounting the poles 2.
