CONNECTING STRUCTURE BETWEEN NEWLY CONSTRUCTED STEEL FLOOR SLAB AND EXISTING GIRDER
PROBLEM TO BE SOLVED: To provide a connecting structure between a newly constructed steel floor slab and an existing girder, wherein only steel is used as a connecting member and the amount of steel used is little.SOLUTION: A connecting structure between a newly constructed steel floor slab 20 having a vertical rib 24 and an existing girder 30 having an upper flange 32 is provided with two L-shaped connecting members 40, 50. Plate parts 42, 52 on one end of the respective two L-shaped connecting members 40, 50 are arranged so as to sandwich the vertical rib 24. The plate parts 42, 52 arranged so as to sandwich the vertical rib 24 and the vertical rib 24 sandwiched thereby are bolt-joined with a bolt 48 penetrating through the plate parts 42, 52 and the vertical rib 24 sandwiched thereby, and plate parts 44, 54 on the other end of the respective two L-shaped connecting members 40, 50 and the upper flange 32 of the existing girder 30 are bolt-joined with a bolt 46 penetrating through the plate parts 44, 54 and the upper flange 32 of the existing girder 30.SELECTED DRAWING: Figure 1
【課題】連結部材として鋼材のみを用い、かつ、用いる鋼材量が少ない、新設鋼床版と既設桁との連結構造を提供する。【解決手段】２つのＬ型連結部材４０、５０を備え、新設鋼床版２０は縦リブ２４を有し、既設桁３０は上フランジ３２を有しており、２つのＬ型連結部材４０、５０のそれぞれの一方の板状部４２、５２は縦リブ２４を挟み込むように配置されており、縦リブ２４を挟み込むように配置された前記それぞれの一方の板状部４２、５２とそれらによって挟み込まれた縦リブ２４とは、前記それぞれの一方の板状部４２、５２およびそれらによって挟み込まれた縦リブ２４を貫通するボルト４８によってボルト接合されており、かつ、前記２つのＬ型連結部材４０、５０のそれぞれの他方の板状部４４、５４と既設桁３０の上フランジ３２とは、前記他方の板状部４４、５４、および既設桁３０の上フランジ３２を貫通するボルト４６によってボルト接合されている。【選択図】図１
