Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation, so as to help understand the content of the present invention.

[0026] The invention is especially suitable for the rapid construction of the prefabricated assembly of steel plate composite beam segments.

[0027] Such as figure 1 As mentioned above, the present invention includes a concrete bridge deck, a steel girder 4-1 and a bridge deck connecting steel plate 2, and the concrete bridge deck is arranged on the steel girder 4-1 through the bridge deck connecting steel plate 2.

[0028] see figure 2 , there is a connection notch on the concrete bridge deck, and the connection notch at the steel girder is a complete connection notch 1-1, and the connection notches at other positions are a partial connection notch 1-2;

[0029] see Figure 4 , the bridge deck connecting steel plate 2 is composed of the outer side plate 2-3 located at the c...

Abstract

The invention provides a seam bolt connection type prefabricated concrete bridge deck and a prefabricating method. The prefabricating method comprises the following steps: erecting a steel main girder and mounting a concrete bridge deck, wherein a bridge deck connection steel plate is mounted when the concrete bridge deck is prefabricated, an outer edge plate is mounted on the outer side of a connection rabbet, an inner edge plate and a side plate with a hole are mounted in the concrete bridge deck and a main girder connection part is welded on the steel main girder, and the main girder connection part is connected with the outer edge plate through a high-strength bolt; and then constructing a bridge deck shearing force rabbet and the connection rabbet. The seam bolt connection type prefabricated concrete bridge deck is simple in structure and relatively high in prefabricating and splicing degree; field construction time is shortened and a construction period is shortened; and prefabricating production and field assembling connection of structural parts can be realized better.

Description

technical field [0001] The invention belongs to the technical field of steel-concrete composite structures in bridges, and in particular relates to a prefabricated concrete bridge deck connected by joint bolts and a prefabrication method. Background technique [0002] In recent years, steel-concrete composite beams have been more and more widely used in engineering. This is not only due to the fact that its structure itself can take advantage of the high compressive strength of concrete and the good tensile performance of steel, but also because it can speed up bridge construction. With the improvement of prefabrication and hoisting capabilities, the segmental prefabrication and assembly technology of steel-concrete composite beams is gradually improving. The so-called prefabricated assembly is an integrated construction process in which bridge components are divided into reasonable segments from their mechanical characteristics, mass-produced in the factory, transported to...
