Zusammenfassung: | To provide a mortar holding tool also used as a connector capable of enhancing a holding power of mortar applied on a surface of skeleton concrete significantly and preventing a fall of detached mortar.SOLUTION: A mortar holding tool A also used as a connector is a member buried in skeleton concrete 60 and holding mortar 63 applied on a surface 61 of the skeleton concrete 60, and comprises a connector part 1 connected with a separator bolt 70 set in a mold form 71, and a support frame 30 mounted to the connector part 1, abutting onto an inner surface of the mold form 71 and surrounding space between the inner surface and an opposite surface 6 of the connector part 1 opposite to the inner surface to create closed space H. A recessed groove 20 is formed on the opposite surface 6 of the connector part 1 facing the mold form 71 on which the mortar 63 is applied. A projection part 21 is formed on an inner peripheral surface of the recessed groove 20 so as to reduce an opening width W of the recessed groove 20.SELECTED DRAWING: Figure 1
【課題】躯体コンクリートの表面に塗着されたモルタルの保持力を飛躍的に高め、剥離モルタルの落下を防ぐことが出来るコネクター兼用モルタル保持具を提供する。【解決手段】コネクター兼用モルタル保持具Aは、躯体コンクリート60内に埋設されて躯体コンクリート60の表面61に塗布されたモルタル63を保持する部材で、型枠71内にセットされるセパボルト70に連結するコネクター部1と、コネクター部1に取り付けられ、型枠71の内面に当接し、内面と前記内面に対するコネクター部1の対向面6との間の空間を囲繞して閉空間Hとする支持枠30とで構成される。モルタル63が塗布されるコネクター部1の型枠71に面する対向面6に凹溝20が形成されている。凹溝20の内周面に凹溝20の開口幅Wを狭くするように凸部21が形成されている。【選択図】図1 |
