Embodiment 1

[0039] A combined bridge, such as figure 1 As shown, it is built on the side of the wooden bridge to be overhauled, used for temporary passage of pedestrians and convenient for overhauling by overhaul personnel. The structure includes a plurality of support members 1, bridge deck members 2 and enclosure members 4 made of wood. The members are connected by tenon and tenon joints. The entire bridge does not need nails. On the one hand, it is fast and convenient to disassemble and assemble, and on the other hand, the bridge is not It may damage itself due to disassembly and assembly.

[0040] Such as figure 1 , figure 2 As shown, the supporting member 1 includes a plurality of fixed columns 11 connected to the guardrail columns of the wooden bridge to be overhauled by connecting pieces 3. The number of fixed columns 11 depends on the number of wooden bridge guardrail columns to be overhauled, and is generally equal . The connecting piece 3 includes a steel rope 31 for binding the ...

Embodiment 2

[0053] The difference from the first embodiment is that each support member 1 includes two fixed posts 11 with a gap. The lower sides of the two fixed posts 11 are fixedly connected by a connecting plate 15. The through holes 115 at the two fixed posts 11 are The connecting plate 15 penetrates, so the two connecting parts 132 can be locked by a locking ring 5. Therefore, each bridge deck member 2 can correspond to the supporting beam 13 one-to-one. After the supporting beam 13 is rotated, the inclination angle of the horizontal bar 21 relative to the ground can be changed, so that it can be applied to arched wooden bridges and the scope of application is increased.

Abstract

The invention discloses a combined bridge and a construction method thereof, involving bridge construction. The combined bridge includes a plurality of support members and a deck member, the support member comprises a plurality of fixing columns connected with the wooden bridge guardrail columns to be repaired through a connecting piece. The upper ends of the fixing columns are vertically connected with fixing blocks, and the lower ends are connected with support beams. The connector comprises a steel rope, two ends of the steel rope are connected through a joint, and the joint comprises two fixed seats which are fixed and connected side by side; the fixed seats are movably provided with U-rings; two ends of the U-rings are threadably connected with fixing nuts; the fixing columns are provided with a plurality of annular grooves; and the bridge deck member comprises a plurality of transverse bars. As a temporary bridge, the bridge is assembled by supporting members and bridge deck members, and the supporting members are attached to the guardrail columns of the original wooden bridge, so that the pile foundation is not required to be driven, the disassembly and assembly are fast andconvenient, and the load-bearing force is mostly borne by the original wooden bridge, so that the load-bearing capacity is strong and the stability is high.

Description

Technical field [0001] The invention relates to bridge construction, in particular to a combined bridge and a construction method thereof. Background technique [0002] Bridges generally refer to structures erected on the rivers and seas to enable vehicles and pedestrians to pass smoothly. They are an important part of road traffic. Common types of bridges vary in structure, depending on the environment in which they are used, such as cable-stayed bridges, arch bridges, and wooden bridges. The stream in the scenic spot is long and winding, and multiple bridges need to be erected for people to pass. In order to integrate the bridge with the natural scenery, the bridges in the scenic spot are often made of wood. However, wooden bridges are exposed to sunlight all the year round and are trampled on by pedestrians. Quality problems such as cracks and rot are prone to occur. Regular inspections and maintenance are required. During maintenance, temporary bridges need to be built nearb...
