<p>The present invention provides an apparatus for fixing a steel wire of a wale. In an embodiment, the present invention has an improved structure capable of fixing the steel wire of a prestressed wale at a location spaced apart from one end of the wale during pit excavation work for constructing an underground structure. The fixing apparatus prevents a sharp angle from being formed in the steel wire, and instead allows the steel wire to extend in the form of an arc shape, thus securing sufficient moment. The fixing apparatus provides strong reinforcement of parts to which high compressive force and high tensile force are applied. In another embodiment, the present invention has an improved structure capable of supporting a bracing beam and fixing and tensioning the steel wire in the bracing beam in corners during pit excavation work. At the corner, the fixing apparatus forms a triangular structure which can stably support the bracing beam and can fix and tension the steel wire at the same time, thus improving work efficiency. Further, the fixing apparatus has a simple structure, thus reducing the consumption of materials and reducing construction expenses.</p> |
