Problems solved by technology

[0003] The advantages of the overhead arch bridge are: the structure of the bridge deck is simple, the construction is convenient, the width of the main load-bearing structure of the bridge span is small, the masonry of the piers and abutments is relatively saved, and the view on the bridge is also wider; the disadvantage is that compared with the girder bridge, The height of the building from the bridge deck to the bottom of the beam is relatively high. When it is used for urban interchanges, the engineering quantity of the cross-strait connection will increase due to the elevation of the bridge deck, or the longitudinal slope of the bridge deck will increase, which will increase the cost and affect the construction cost. bad driving

Embodiment

[0033] Embodiment: a kind of pull-down double-deck arch bridge, its structure is as Figure 1-6 As shown, it includes three main arch rings 1, transverse connecting systems 2, arch structures 3, bridge deck systems 4, columns 5 and suspenders 6. Among them, the upper parts of the three main arch circles 1 support the arched building 3 through the columns 5, the adjacent main arch circles 1 are reinforced by the transverse connection system 2, and the lower parts of the three main arch circles 1 are connected with a plurality of suspenders 6, Any suspension rod 6 does not coincide with the center line of any column 5 .

[0034] Because the hollow arch structure is beneficial to reduce the transverse load, and the structure is light and beautiful, so the arch structure 3 in the present invention adopts the hollow structure, including the multi-hole structure and the bridge deck system 4 . The overarching structure 3 includes a deck system 4 having an upper deck system and a low...

Abstract

The invention relates to a pull-down deck type double-layer arch bridge and belongs to the technical field relevant to constructional engineering. The arch bridge mainly comprises a plurality of main arch rings. The upper portions of the main arch rings are fixedly connected with spandrel structures through stand columns. The lower portions of the main arch rings are fixedly connected with the lower-layer bridge floor through suspenders. The adjacent main arch rings are reinforced through transverse connecting systems. The arch bridge provided by the invention has the two layers of bridge floors, the main arch rings are used for bearing the mass of the upper-layer bridge floor and the mass of the lower-layer bridge floor, and the dual advantages of deck type arch bridges and through arch bridges are achieved.

Description

technical field [0001] The invention relates to the technical field related to construction engineering, in particular to a pull-down and top-supporting double-layer arch bridge. Background technique [0002] Arch bridge is one of the basic bridge systems. It has a long history and beautiful appearance. It is suitable for crossing rivers, highways and railways. It is developing rapidly in our country. The deck of the overhead arch bridge is set on the arch rib of the main load-bearing structure of the bridge span. [0003] The advantages of the overhead arch bridge are: the structure of the bridge deck is simple, the construction is convenient, the width of the main load-bearing structure of the bridge span is small, the masonry of the piers and abutments is relatively saved, and the view on the bridge is also wider; the disadvantage is that compared with the girder bridge, The height of the building from the bridge deck to the bottom of the beam is relatively high. When it...
