Construction method of spray prefabricated T-beam

Abstract

The invention relates to a construction method of spraying prefabricated T beams, comprising the steps of: 1) preparation of pedestal; 2) binding and installation of steel bars; 3) making of formwork; 4) installation of formwork; 5) pouring concrete; 6) vibrating concrete; 7) Formwork removal; 8) Concrete maintenance; 9) Wastewater recycling. The beneficial effects of the present invention are: the present invention arranges horizontal jacks on both sides of the T-beam pedestal as push-out demoulding devices, and the end molds are connected and fixed with the pedestal through anchor bolts, which can improve the integrity and stability of the T-beam formwork; The top platform and electric hoist are set above the T-beam formwork, which can not only temporarily fix and position the steel cage, but also drive the vibrating rod to vibrate the concrete at different parts, improving the quality of concrete vibrating; The sprinkler bracket is equipped with a swinging sprinkler head on the top, sprinkler bracket side frames are installed on both sides, and a hidden sprinkler head is installed inside the T-beam pedestal, which can spray the T-beam in an all-round way for health preservation.

Description

technical field [0001] The invention relates to a T-beam construction method, in particular to a spray prefabricated T-beam construction method, which 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, high reliability, convenient construction and industrialization have become urgent problems in the design of expressway bridges. The mechanization of bridge construction has made the application of T-beam expressway bridges more and more common, and the efficiency of bridge construction has also increased day by day. [0003] Since T-beams are widely used in the construction of highway bridges, the maintenance control problems of T-beams are also increasingly exposed. The traditional automatic spraying maintenance of beams and slabs installs nozzles on bot...

AI Technical Summary

Problems solved by technology

[0004] To sum up, although the existing T-beam maintenance has achieved good construction results under suitable working conditions, there are still deficiencies in the aspects of T-beam all-round spraying maintenance, spraying maintenance efficiency, and wastewater recycling and reuse.
