Embodiment 1

[0040] Such as Figure 1 to Figure 6 As shown, an assembled bridge deck includes a steel bridge deck and a structural layer 1 laid on the steel bridge deck, and connecting bolt holes 5 are arranged around the steel bridge deck.

[0041] In the prior art, the construction method of orthotropic steel-ultra-high-performance concrete composite bridge deck is to pour ultra-high-performance concrete on-site after the construction of orthotropic steel bridge deck is completed. The biggest disadvantage of on-site pouring is that the quality of concrete pouring is difficult to control , while ultra-high-performance concrete has strict requirements for construction quality, and its good mechanical performance and durability are all based on the premise that the construction quality meets the standard. At the same time, ultra-high-performance concrete has strict requirements on curing conditions. Generally, high-temperature steam curing is required, and special curing equipment is requir...

Embodiment 2

[0045] Such as Figure 1 to Figure 6 As shown, this embodiment is further limited on the basis of Embodiment 1: As a specific implementation of the steel bridge deck, the steel bridge deck includes a top plate 2, longitudinal ribs and transverse ribs 4, and there are multiple longitudinal ribs, The longitudinal ribs are parallel to each other, and the upper parts of the longitudinal ribs are fixedly connected with the top plate 2;

[0046] The transverse rib 4 and the longitudinal rib are perpendicular to each other, the transverse rib 4 is fixedly connected to each longitudinal rib, and the lower end of the transverse rib 4 is lower than the lower end of the longitudinal rib;

[0047] The structural layer 1 is laid on top of the roof 2;

[0048] Bolt holes 5 are provided around the top plate 2 , at both ends of the longitudinal ribs, and at both ends of the transverse ribs 4 .

[0049] In this scheme, the lower end of the transverse rib 4 is used as the connection part betw...

Embodiment 3

[0062] This embodiment further defines this case on the basis of any one of the technical solutions provided by any one of the above embodiments, such as Figure 1 to Figure 6 As shown, as a person skilled in the art, the adjacent fabricated bridge decks can be staggered up and down, and left and right staggered to realize the direct connection between the adjacent fabricated bridge deck steel bridge decks, but The above connection methods are inconvenient to determine the position of each fabricated bridge deck on the lower steel member of the bridge. Therefore, the connecting plate 3 is also included, and the connecting plate 3 is used as an intermediate connector between two adjacent fabricated decks to realize the Bolted connections between fabricated deck steel bridge decks. The connecting plate 3 is used as an intermediate connector between adjacent fabricated bridge decks, such as a plate-shaped structure provided with bolt holes, so that after the assembled bridge deck...

Abstract

The invention discloses an assembled bridge deck slab comprising a steel bridge deck slab and a structural layer laid on the steel bridge deck slab. Connecting bolt holes are disposed at four sides of the steel bridge deck slab. The assembled bridge deck slab facilitates implementation of factory prefabrication so as to obtain a high-quality bridge deck slab under favorable manufacturing conditions; moreover, the bridge deck slab has ideal interchangeability. Thus, the speed of recovering road passage can be increased, and repair of damaged bridge deck slab under ideal maintenance conditions is facilitated so as to increase the material utilization rate.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to an assembled bridge deck. Background technique [0002] In view of the shortcomings of orthotropic steel bridge decks such as insufficient local stiffness, prominent fatigue problems, and easily damaged pavement, orthotropic steel-concrete composite bridge decks have been more and more used. Among many composite bridge decks, orthotropic steel-ultra-high performance concrete composite bridge decks have been rapidly developed due to their light weight and high tensile and compressive properties of concrete. [0003] The orthotropic steel-ultra-high-performance concrete composite bridge deck is to lay an ultra-high-performance concrete layer on the orthotropic steel bridge deck, and the two are connected by shear connectors to achieve the effect of joint stress and reduce the orthogonality. The stress state of the anisotropic steel bridge deck, while improving the local...
