CONSTRUCTION OF FOOTING BEAM AND EARTHEN FLOOR SLAB ON BEARING SLAB FOUNDATION CONCRETE

摘要

PURPOSE:To eliminate accuracy of fittings and removal of a form (inside), a ceiling form and a support in a conventional construction method, at the same time, contribute to the accuracy of beam size and to reduce greatly a construction period and the number of building materials. CONSTITUTION:A plurality of rectangular plastic boxes 1 are arranged and fixed at intervals by width size of a footing beam B, and reinforcing bars 2 are arranged to the surroundings and upper surfaces of the plastic boxes 1. In addition, forms (outside) 3 are so fitted that the surroundings of the whole are surrounded. Intervals between the forms (outside) 3 and boxes 1 are respectively bolted to connect every required pitch so that each of the intervals reaches width width size of the footing beam B and, at the same time, an interval between the boxes 1 and 1 is connected with a proper connector 4 every required pitch. Concrete is placed until it reaches a level of thickness of an earthen floor slab C from the upper surface of the box 1.
