PURPOSE:To concurrently form the foundation and beams of concrete by a method in which the iron bars for beams and foundation are fixed to an iron bar groove on the upside of a receiving base installed between left and right formworks on the ground and formworks for beams are assembled on the reciving base through a matching base. CONSTITUTION:Form plates 6 for foundation concrete 4 are installed on both left and right-handed sides on the horizontally leveled ground 7, iron-bar grooves 15 are provided on the left and right-handed sides of the upside 8, and U-shaped receiving bases 1 having an iron-bar groove 12 on its center are installed at an interval permitting a beam formwork 17 to support between the form plates 6. Also, built-up iron bars 14 are fitted into the left and right-handed iron-bar grooves 15, the lower end bars 11 of the iron bars 10 for assembling beams are fitted into the central iron-bar groove 12 and vertically installed, and the face 16 of the matching base 2 is placed on the receiving base 1 to stabilize the built- in iron bars 10 and 13. Then, the formwork 17 is fitted into the formfram groove 18 of the matching base 2 and held, and then concrete is placed into the formworks 16 and 17 to form the foundation 4 and the beams 19 concurrently. |
