The invention provides a high-temperature steam curing construction method for a prefabricated
bridge deck of a UHPC steel-concrete composite beam without coarse aggregate. The method comprises the following steps that 10, steel bars are blanked and machined, specifically, the steel bars are machined and distributed in a centralized mode in a factory; 20, a mold is installed, specifically, a formwork of the
bridge deck is installed, and the formwork comprises a bottom mold, a transverse side mold and a longitudinal side mold; 30, the steel bars and embedded parts are installed, specifically, an upper layer of
steel bar net and a lower layer of
steel bar net which are arranged in a spaced mode are installed on the formwork through the steel bars, and the embedded parts are installed on the formwork; and 40, concrete is mixed, specifically, a premix
package with the concrete prefabricated and an additive and steel
fiber formula
package are included, and the premix
package and the formula package are put into a stirrer till the concrete is mixed and discharged out of a
station. According to the high-temperature steam curing construction method for the prefabricated
bridge deck of the UHPC steel-concrete composite beam without the coarse aggregate, the self-weight load of the structure can be reduced, the design is lighter and more economical, and the common problem of
cracking of the bridge
deck and the like can be well solved.
