Construction method of spraying prefabricated T beam

Abstract

The invention relates to a construction method of a spraying prefabricated T beam. The construction method comprises the following steps of 1) preparing a pedestal; 2) binding and mounting reinforcingsteel bars; 3) manufacturing a mod plate; 4) mounting the mold plate; 5) pouring concrete; 6) vibrating the concrete; 7) removing the mold; 8) concrete curing; and 9) wastewater recovery. The construction method has the beneficial effects that horizontal jacks are arranged on the two sides of the T-beam pedestal to serve as jacking demolding devices, end molds are fixedly connected with the pedestal through anchoring bolts, and the integrity and stability of the T-beam formwork can be improved; a top platform and an electric hoist are arranged above the T-beam formwork, so that a reinforcement cage can be temporarily fixed and positioned, a vibrating rod can be driven to vibrate concrete at different parts, and the concrete vibrating quality is improved; and an adjustable rear-mounted movable spraying support is adopted, a swing spray head is mounted at the top, spray support side frames are mounted on the two sides, and a buried spraying head is arranged in the T beam pedestal, so that the T beam can be subjected to omnibearing spray curing.

Description

Technical field [0001] The invention relates to a T beam construction method, in particular to a spray prefabricated T beam construction method, and belongs to the field of civil engineering. Background technique [0002] With the rapid economic growth, the whole society also has an urgent need for the development of expressways. In order to meet the requirements of rapid development and economic energy saving, economy, strong reliability, convenient construction and factoryization have become urgent problems in highway bridge design. The mechanization of bridge construction has made the application of T-beam highway bridges more and more common, and it has also increased the efficiency of bridge construction. [0003] As T-beams are widely used in the construction of highway bridges, the maintenance and control problems of T-beams are increasingly exposed. The traditional automatic spray curing of beams and slabs are installed with sprinklers on both sides of the beams. The sprin...
