Matrix construction method for concrete casting of bridge slabs

摘要

PURPOSE: A method for building a mold is provided to connect and fix a flange of a form and a girder to a holder and to build a mold on the girder. CONSTITUTION: A fixing pin(22) is lengthwise combined to the upper part of a girder at a certain interval. A clamp(17) is fixed to the fixing pin on the girder at a certain interval. A holder(13) is adhered on the entire lengthwise part of an upper wing(21) of the girder and combined by the clamp and a bolt(18). Forms(12a) are fixed to the girder and the fixing pin of the girder and to the holder fixed to the clamp. Balks(15) of a regular size are arranged lengthwise on the upper part of the form and combined to the form. Veneer boards(16) of a regular size are placed and the fixed to the balks. Thereby, a mold for grouting concrete on a slab(26) between the girders is acquired.
