Portion is arranged in concrete end floor beam；
Also include being arranged at reinforcing bar and channel-section steel in concrete end floor beam, Wavelike steel webplate end set have for reinforcing bar pass through to
Few pass through aperture；It is correspondingly arranged on the two side of channel-section steel and the partially or fully distribution form phase of the through hole on Wavelike steel webplate
With through hole, Wavelike steel webplate end is partially or fully arranged in the groove of channel-section steel, reinforcing bar simultaneously through positioned at channel-section steel and
Through hole on Wavelike steel webplate.
Further, reinforcing bar is simultaneously through the channel-section steel at least corresponding to two Wavelike steel webplates.
Further, the end that Wavelike steel webplate is arranged in concrete end floor beam is planar structure, and reinforcing bar perpendicular to
Planar structure.
Further, when the quantity of through hole is more than for the moment, through hole is uniformly distributed along planar structure.
Further, rebar surface is provided with screw thread.
Further, what channel-section steel outer surface was orderly is provided with protrusion.
Further, protrusion is the peg being fixedly connected with channel-section steel outer surface.
After employing above-mentioned technical proposal, the present invention has following beneficial effect：
By setting channel-section steel, Wavelike steel webplate end is partially or fully arranged in the groove of channel-section steel, and passes through some reinforcing bars
Intersection through above-mentioned channel-section steel Yu Wavelike steel webplate end so that when Wavelike steel webplate produces longitudinal tension stress, concrete
The power being subject to effectively is disperseed by channel-section steel and some reinforcing bars, so as to prevent due to concrete stress concentrate and caused by office
Portion crack, when Wavelike steel webplate end area is larger, can be set multiple channel-section steels it is corresponding with a Wavelike steel webplate, or pass through by
Reinforcing bar runs through channel-section steel corresponding with multiple Wavelike steel webplates simultaneously, can preferably realize above-mentioned purpose.
