PIPING INSTALLATION STRUCTURE AND PIPING PIT CONSTRUCTION METHOD
To provide a piping installation structure and a piping pit construction method capable of shortening a construction period while suppressing a height of a pit where equipment piping is installed.SOLUTION: A piping installation structure has a foundation beam 18 where a precast concrete reverse haunch part 20 having a beam depth lower than both ends is formed in the central part thereof, and equipment piping 34 which is mounted on the reverse haunch part 20 and extends in a direction perpendicular to the reverse haunch part 20. A piping pit construction method includes the steps of installing a precast concrete reverse haunch part 20 as a central part of a foundation beam 18, mounting equipment piping 34 extending in a direction perpendicular to the reverse haunch part 20, on the reverse haunch part 20, forming a cast-in-place concrete beam part 22 having a beam depth higher than the reverse haunch part 20 on both ends of the reverse haunch part 20 and constructing the foundation beam 18, and constructing a slab 14 on the foundation beam 18 and constructing a pit 16.SELECTED DRAWING: Figure 1
【課題】設備配管を設置するピットの高さを抑えつつ、工期を短縮することができる配管設置構造及び配管ピット構築方法を提供する。【解決手段】配管設置構造は、両端部より梁成が低くされたプレキャストコンクリート造の逆ハンチ部２０が中央部に形成された基礎梁１８と、逆ハンチ部２０に載置され、逆ハンチ部２０と直交する方向へ延びる設備配管３４と、を有する。また、配管ピット構築方法は、基礎梁１８の中央部としてのプレキャストコンクリート造の逆ハンチ部２０を設置する工程と、逆ハンチ部２０と直交する方向へ延びる設備配管３４を逆ハンチ部２０に載置する工程と、逆ハンチ部２０の両端部に逆ハンチ部２０より梁成が高い現場打コンクリート梁部２２を形成して基礎梁１８を構築する工程と、基礎梁１８の上にスラブ１４を構築してピット１６を構築する工程と、を有する。【選択図】図１
