Embodiment 1

[0019] Such as Figure 1-Figure 4 As shown in the present embodiment, a connecting device between a plate girder and a cover beam of a mid-mountain bridge on a large longitudinal slope mountainous road described in this embodiment includes a plate girder 1 and a cover beam 2, and each plate girder is along the bottom surface in contact with the cover beam Two triangular wedges 3 are arranged in the direction of the transverse bridge, and two steps 4 are correspondingly arranged on the top surface of the cover beam under each plate girder. The contact surface is in a horizontal state; the triangular wedge is a right-angled triangular wedge, and the right-angled side of the right-angled triangular wedge is attached to the bottom surface and side wall of the step; An anchoring steel bar 5 is set, and the anchoring steel bar penetrates into the plate girder through the connection of adjacent triangular wedges; on the cover beam at the uphill end, a PVC pipe 6 is vertically arrange...

Embodiment 2

[0022] Such as figure 1 , image 3 , Figure 5 , Figure 6 As shown in the present embodiment, a connecting device between a plate girder and a cover beam of a mid-mountain bridge on a large longitudinal slope mountainous road described in this embodiment includes a plate girder 1 and a cover beam 2, and each plate girder is along the bottom surface in contact with the cover beam Two triangular wedges 3 are arranged in the direction of the transverse bridge, and two steps 4 are correspondingly arranged on the top surface of the cover beam under each plate girder. The contact surface is in a horizontal state; the triangular wedge is an acute-angled triangular wedge, and its angle is ≥ 60 degrees, < 90 degrees; on the cover beam at the downhill end, the anchoring reinforcement 5 is vertically arranged at the junction of adjacent steps, and the The anchoring reinforcement penetrates into the plate girder through the connection of adjacent triangular wedges; on the cover beam a...

Abstract

The invention belongs to the technical field of the bridge engineering constructionparticularto a device of half-hillside bridge in large longitudinal slope mountain road. In the connection device between plate girder and cover girder of half-hillside bridge in large longitudinal slope mountain road, anchor steel bars are arranged on cover girder of downhill end and the connection part of adjacent steps, the anchor steel bars go in plate girder through the connection part of adjacent triangular wedges; PVC pipe is vertically arranged on cover girder of uphill end and the connection part of adjacent steps, the anchor steel bars are inserted vertically in the PVC pipe and go in the plate girder through the connection part of adjacent triangular wedges, at the same time the gap between the PVC pipe and the anchor steel bar is filled with pitch; larger longitudinal displacement of the upper structure of the bridge is avoided effectively through the anchor steel bar arranged between the end part of the plate girder and cover girder in the mode of the semi-flexible, semi-rigid connection, so that the safety of the bridge is guaranteed well, longitudinal more than 4% of half-hillside bridge in mountain road can be applied.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering construction, and in particular relates to a device on a half-mountain bridge on a mountain road with a large longitudinal slope. Background technique [0002] Banshan Bridge is rarely used in similar projects in China, and there are few studies on the design and construction of important parts of this type of structure. During the design and construction of the project, problems such as small bending radius and large longitudinal slope are faced Especially when there are many continuous downhill sections, it may cause the girder slab resting on the cover beam on the longitudinal slope to slide down, and even cause the bridge to collapse. In bridge design, according to the "General Code for Design of Highway Bridges and Culverts", the longitudinal slope of bridges should not be greater than 4%. posed certain difficulties. [0003] At present, in order to reduce the longitudinal slidin...
