WOODEN BRIDGEConstruction case

SUSPENSION BRIDGE

Nonreinforced suspension bridge design structure

A structure that supports load via the bridge structure and cables without a pylon,
this construction method is an eco-friendly one introduced competitively by local governments that brings together
a maximum of nature conservation and beautiful molding of the bridge itself.

PATENTS

Wooden bridge patents

At Segaon, we carry out constant research and development to produce wooden bridges that are both beautiful and robust.

Reinforced arch bridge installation structure
(Patent no. 10-1843878)

A structure characterized by horizontal cables able to adjust tension installed on both lower ends of the arch ribs and a vertical cable able to adjust tension installer in the center of the reinforced girder, which prevents the arch ribs from slipping, blocks repulsive force at the end of the arch ribs, reduces the size of the shifts structure and alleviates deflection of the central part of the arch ribs and reinforced girders.
Wooden structure with gap prevention applied
(Patent no. 10-0990801)

Patent-applied structure

An applied elastic rubber ring fundamentally blocks moisture inflow that leads to shrinkage and deformation of wood. Without exposed gaps, corrosion, vibration and movement are prevented.

Structure without patent application

After a certain period of time elapses after construction, up, down, left and right movement, rotation, and vibration occur due to the contraction of the wood. Rapidly shortening occurs.

Wood shrinkage gap prevention device
(Patent no. 10-0721666)

To prevent the occurrence of gaps in bolted joints due to deformation via shrinking of wooden railings, pillars, support beams, etc., a special type of spring compensates for contraction via displacement for a structure with a maintained bolted rigidity that does not require maintenance.

Board spring form

A chevron-shaped board spring compensates for shrinkage in the wood.

Coil spring form

A spiral coal spring compensates for shrinkage in the wood.
Bearing for wooden bridges
(Patent no. 10-0767172)

To prevent the occurrence of gaps in bolted joints due to deformation via shrinking of wooden railings, pillars, support beams, etc., a special type of spring compensates for contraction via displacement for a structure with a maintained bolted rigidity that does not require maintenance.
