摘要

PURPOSE: A latticed precast reinforced concrete girder is provided to reduce troublesomeness caused by installing a slab form duplicate in a construction field and to construct economically and rapidly by standardized production in a factory. CONSTITUTION: A latticed precast reinforced concrete girder comprises: a grid girder(1) composed of concrete girders(2) arranged in a latticed form to be parallel at regular intervals horizontally and vertically, wherein the length of the outermost concrete(2a) among the concrete girders(2) is a little shorter not to be intersected mutually; and a connection instrument(3) installed on the end of the concrete girder(2a) of the four corners of the grid girder(1) to connect with a column.
