REINFORCEMENT STRUCTURE FOR USE DURING FLOOR SLAB REPLACEMENT AND FLOOR SLAB REPLACEMENT METHOD
To improve durability in respect to the downward load on existing floor slabs.SOLUTION: In a reinforcement structure for use during floor slab replacement where a part of an existing floor slab 3 laid above a bridge girder is removed and a new floor slab 30 is newly installed adjacent to the existing floor slab 3 remaining above the bridge girder, a lower surface 3s of the existing floor slab 3 is supported by a bracket extending from the new floor slab 30 newly installed adjacent to the existing floor slab 3 remaining above the bridge girder to the lower surface 3s of the existing floor slab 3. As a result, the downward load on the existing floor slab 3 is supported by the new floor slab 30, which is new and superior in strength to the existing floor slab 3. Thus, the durability in respect to the downward load of the existing floor slab 3 can be improved. Conversely, since the bracket and the lower surface 3s of the existing floor slab 3 are separated, the downward load applied to the new floor slab 30 is not transmitted to the existing floor slab 3. It is possible to prevent a load being applied to the existing floor slab 3 due to the downward load of the new floor slab 30.SELECTED DRAWING: Figure 8
【課題】既設床版の下方への荷重に対する耐久力を向上させる。【解決手段】橋桁の上に架設された既設床版３の一部を撤去し、橋桁の上に残存する既設床版３に隣接して新たに新設床版３０を設置する床版入替時の補強構造において、橋桁の上に残存する既設床版３に隣接して新たに設置された新設床版３０から既設床版３の下面３ｓへと延在するブラケットにより既設床版３の下面３ｓが支持される。これにより、既設床版３に対する下方への荷重が既設床版３よりも新しく強度に優れる新設床版３０により支持されるため、既設床版３の下方への荷重に対する耐久力を向上させることができる。一方、ブラケットと既設床版３の下面３ｓとは分離しているため、新設床版３０に対する下方への荷重は既設床版３には伝達されず、新設床版３０の下方への荷重により既設床版３に負担が生じることを防止することができる。【選択図】図８
