Embodiment 1
[0043] A ring-type steel corbel joint for connecting beamless floors and reinforced concrete columns shown in Figures 6 to 8 is one of the specific embodiments of the present invention, including reinforced concrete columns 2 and beamless The floor 1 and the steel corbels 3 provided at the joints, there are four steel corbels 3, and the angle between two adjacent steel corbels 3 is 90°. The four steel corbels 3 are non-piercing, and intersect to form a well-shaped structure, that is, the steel corbels 3 do not pass through the beamless floor 1, and the upper and lower parts of the beamless floor 1 are provided with criss-crossing Slab gluten 11, steel corbel 3 is provided with column longitudinal reinforcement 21 and column stirrup 22, because it is non-piercing type, column longitudinal reinforcement 21 bends outward along the horizontal direction when extending into beamless floor 1, and Be fixed on the beamless floor 1. The steel corbel 3 is located at the intersection of ...
Embodiment 2
[0045] A ring-type steel corbel joint for connecting beamless floors and reinforced concrete columns shown in Figures 9 to 12 is the second specific embodiment of the present invention. The difference from the previous embodiment is that the surrounding reinforced concrete The number of steel rings of the column 2 is two circles, which are inner and outer steel rings respectively, and the inner steel ring is tightly bound to the column, and the width of the lower ring plate 42a on the steel ring is greater than the width of the upper ring plate 41a ; And the radial width of the upper and lower ring plates 41b, 42b on the outer steel ring is the same. The distance between two adjacent rings of steel rings is 1.5 to 2.5 times the height of the hidden beams of the floor.
Embodiment 3
[0047] A ring-type steel corbel joint for connecting beamless floors and reinforced concrete columns shown in Figures 13 and 14 is the third specific embodiment of the present invention. The difference from the previous embodiment is that the steel corbel 3 is a through-heart type, that is, the steel corbel 3 passes through the beamless floor 1. Other structures are the same as in Embodiment 2.
