Embodiment 1

[0039] A composite bridge such as figure 1 As shown in the figure, it is built on the side of the wooden bridge to be repaired, which is used for temporary passage of pedestrians and is convenient for maintenance personnel to carry out maintenance. Its structure includes multiple support members 1, bridge deck members 2 and enclosure members 4 made of wood. The members are connected by mortise and tenon. The whole bridge does not need to use nails. It may be damaged due to disassembly.

[0040] Such as figure 1 , figure 2As shown, the support member 1 includes a plurality of fixed columns 11 connected with the wooden bridge guardrail columns to be overhauled through the connector 3, and the number of fixed columns 11 depends on the number of the wooden bridge guardrail columns to be overhauled, generally equal to . The connecting piece 3 includes a steel rope 31 for binding the fixing column 11 and the guardrail column together. The fixing column 11 is provided with three...

Embodiment 2

[0053] The difference from Example 1 is that, if Figure 4 As shown, each support member 1 includes two fixed columns 11 with gaps, the lower sides of the two fixed columns 11 are fixedly connected by a connecting plate 15, and the through holes 115 at the two fixing columns 11 pass through the connecting plate 15 , so the two connecting parts 132 can be locked by one locking ring 5 . Therefore, each bridge deck member 2 can correspond to the support beam 13 one by one, and the angle of inclination of the horizontal bar 21 relative to the ground can be changed after the support beam 13 is rotated, so that it can be applied to the arched wooden bridge 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 its construction method. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly, and are an important part of road traffic. Common types of bridges have various structures, depending on the environment in which they are used, such as cable-stayed bridges, arch bridges, and wooden bridges. The stream in the scenic area is long and winding, and multiple bridges need to be erected for people to pass. In order to integrate the bridges with the natural scenery, the bridges in the scenic area are often made of wood. However, wooden bridges are exposed to the sun all the year round and are trampled by pedestrians. They are prone to cracks, rot and other quality problems. They need to be repaired and maintained regularly. During maintenance, temporary bridges need to be built ne...
