摘要： PROBLEM TO BE SOLVED: To provide a construction method of a bridge floor slab and a joint structure of a precast floor slab capable of installing more precast floor slabs during one night work with extra time to deal with a contingency situation than a conventional construction method, reinforcing a joint section, and using a general precast floor slab which is commercially available. SOLUTION: A construction method of a bridge floor slab of the present invention comprises: a precast floor slab laying process to lay down a precast floor slab on a predetermined position; a temporary lining plate installation process to install a temporary lining plate over upper surfaces of the two precast floor slabs opposite to each other through a joint section; a temporary lining plate removal process to remove the temporary lining plate; and a concrete placing process to place infill concrete in a space created at the joint section. The construction method of the bridge floor slab executes the precast floor slab laying process and the temporary lining plate installation process prior to the temporary lining plate removal process and the concrete placing process which are collectively executed for two or more joint sections after the same at the predetermined positions are constructed.
