Abstract

The invention discloses a wide prefabricated bridge deck slab, and relates to the field of civil engineering. According to the technical scheme, the prefabricated bridge deck slab is characterized bycomprising a metal net and a concrete layer wrapping the metal net; the metal net is pulled out to form the pre-camber; the concrete layer forms the same pre-camber along with the pre-camber of the metal net, and the prefabricated bridge deck slab is formed. Longitudinal and/or transverse rib plates are arranged above the prefabricated bridge deck slab. A plurality of through holes are formed in the rib plates, and the opening directions of the through holes are perpendicular to the length directions of the rib plates; reinforcing steel bars penetrate through the through holes and are fixedlyconnected with the through holes. According to the invention, the reinforcing steel bars penetrate through the through holes in the rib plates, so that when concrete is poured in subsequent field construction, the binding power between the concrete cured after prefabrication and the concrete newly poured in situ is increased, and the cracking phenomenon is reduced. Meanwhile, the invention furtherdiscloses a construction method of the wide prefabricated bridge deck slab.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a wide-width prefabricated bridge deck and a construction method thereof. Background technique [0002] In order to reduce self-weight and save materials, steel-concrete composite beams developed in the 20th century combined the advantages of concrete beams and steel beams in a relatively simple way. A large number of engineering examples show that the composite structure not only has good mechanical performance, but also inherits the advantages of steel structure and concrete structure in terms of construction performance, durability, and economy. Compared with ordinary reinforced concrete structures, the comprehensive benefits have strong advantages. Competitiveness. In order to save on-site construction time, at present, factory prefabricated concrete bridge decks and steel girders are mostly used, and bridge decks are hoisted and spliced ​​on site, and wet joints are poured ...
