CONCRETE FLOOR SLAB JOINT STRUCTURE, CONCRETE FLOOR SLAB JOINING METHOD, AND CONCRETE FLOOR SLAB MANUFACTURING METHOD
To improve strength both before and after joining while allowing for easy positioning during joining.SOLUTION: A concrete floor slab joint structure 1 in which a first end face 11 of a first concrete floor slab 10 and a second end face 21 of a second concrete floor slab 20 are joined, comprises: a protrusion 12 provided on the first end face 11 of the first concrete floor slab 10 and a recess 22 provided on the second end face 21 of the second concrete floor slab 20. The protrusion 12 and recess 22 are fitted with each other, thus the first end face 11 of the first concrete floor slab 10 and the second end face 21 of the second concrete floor slab 20 can be easily aligned, and positioning facilitated during joining. Further, as the protrusion 12 and the recess 22 are formed of a fiber reinforcement concrete 93, the strength of the protrusion 12 and the recess 22 both before and after joining can be improved. Therefore, it is possible to improve the strength both before and after joining while facilitating positioning during joining.SELECTED DRAWING: Figure 1
【課題】接合する際の位置決めを容易にしつつ、接合前及び接合後における強度を向上させる。【解決手段】第１コンクリート床版１０の第１端面１１と第２コンクリート床版２０の第２端面２１とが接合されているコンクリート床版の接合構造１において、第１コンクリート床版１０の第１端面１１に設けられた凸部１２と、第２コンクリート床版２０の第２端面２１に設けられた凹部２２とを備え、凸部１２と凹部２２とは互いに嵌合するため、第１コンクリート床版１０の第１端面１１と第２コンクリート床版２０の第２端面２１とを合わせ易く、接合する際の位置決めが容易である。また、凸部１２及び凹部２２は繊維補強コンクリートに９３より形成されているため、接合前及び接合後における凸部１２及び凹部２２の強度を向上させることができる。したがって、接合する際の位置決めを容易にしつつ、接合前及び接合後における強度を向上させることができる。【選択図】図１
