Embodiment Construction

[0034] The technical solution in the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiment in the description is only used as an example, and all other embodiments obtained by those skilled in the art without making creative work, All belong to the protection scope of the present invention.

[0035] Such as Figure 1-Figure 6 As shown, the assembled steel-wood composite arch bridge structure described in this specific embodiment is formed by successively connecting several space dodecahedrons; the space dodecahedron includes several corner connectors 1 and structural rod units 2;

[0036] The corner connector 1 includes a three-way connector 1-1 and a four-way connector 1-2;

[0037] The structural rod unit 2 includes a single structural rod 2-1 and a split structural rod 2-2; the split structural rod 2-2 is two semi-cylindrical bodies that are symmetrical and connected by mortise and tenon st...

Abstract

The invention discloses a fabricated steel-wood combined arch bridge structure and a construction method thereof, and relates to the technical field of bridge construction, the fabricated steel-wood combined arch bridge structure is formed by sequentially connecting a plurality of spatial dodecahedrons; the spatial dodecahedron comprises a plurality of corner connecting pieces and structural rod piece units; the corner connecting piece comprises a three-way connecting piece and a four-way connecting piece; each structural rod piece unit comprises a single structural rod and a split structural rod; the split structure rod is formed by two symmetrical semi-cylinder structures which are movably connected in an inserted mode through a tenon-and-mortise structure. The three adjacent single structural rods in the same space dodecahedron are connected through three-way connecting pieces; the five four-way connecting pieces located at the connecting face positions of every two adjacent space dodecahedrons are connected with two single structure rods and two split structure rods respectively. The bridge structure is diversified, good in stress condition and excellent in structural stability, and by combining light high-strength materials, the bridge structure is light in self weight, has the space utilization rate and attractive shape, and breaks through a traditional bridge structure form at the same time.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an assembled steel-wood composite arch bridge structure and a construction method thereof. Background technique [0002] A bridge is a structure built to cross obstacles. According to its form and structure, it is mainly divided into beam bridge, truss bridge, arch bridge, cable-stayed bridge, suspension bridge and so on. The current bridge structure is relatively traditional and lacks breakthroughs. Contents of the invention [0003] The object of the present invention is to aim at the defects and deficiencies of the prior art, to provide an assembled steel-wood composite arch bridge structure and its construction method, which are diversified, have good stress conditions, and have excellent structural stability, combined with light weight and high strength The material makes it light in weight, has both space utilization rate and beautiful shape, and breaks the t...
