Tape splicing embedded bar is usually straight muscle, can cause the fatigue problem of reinforcing bar in wet seam.
Summary of the invention
To solve the above problems, the invention discloses a kind of wet seam constructions of floorings U-shaped reinforcing bar and construction for exempting from bed die
Method, power transmission efficiency is high, is easy to construct, good integrity.
In order to achieve the above objectives, technical scheme is as follows：
A kind of wet seam construction of floorings U-shaped steel muscle for exempting from bed die, it is characterised in that：Including two prefabricated bridges, U-shaped steel
Muscle, longitudinal reinforcement, cast-in-place concrete, leakproof reinforcing bar, the U-shaped reinforcing bar are embedded in prefabricated bridge, from the contiguous prefabricated beam wing
The U-shaped reinforcing bar that listrium stretches out is laterally staggered along floorings, and penetrates longitudinal reinforcement, two prefabricated bridges in its knee
Opposite face lower horizontal to there is a step, two prefabricated bridges are in the vertical V-shaped groove in seam crossing side, the leakproof reinforcing bar
It is arranged in v-depression, the step and leakproof reinforcing bar form the bottom plate being closed, and pour cast-in-place concrete above bottom plate.
Further, the prefabricated bridge step with a thickness of the 1/3 ~ 1/4 of floorings overall thickness.
Further, the intensity of the cast-in-place concrete is C40 ~ C60 or ultra-high performance concrete.
A kind of construction method of the wet seam of floorings U-shaped steel muscle that exempting from bed die, includes the following steps：
1）Make floorings steel mesh and U-shaped reinforcing bar；
2）Batch production prefabricated bridge, U-shaped reinforcing bar expose the side of bridge deck concrete, and prefabricated bridge is perpendicular in seam crossing side
To V-shaped groove, prefabricated bridge side horizontal is to forming step configuration；
3）Prefabricated bridge is transported to erecting bed, lift using the U-shaped reinforcing bar of exposing in place；
4）A longitudinal leakproof reinforcing bar, other longitudinal reinforcements and U are placed in the lower end V-shaped part of contiguous prefabricated floorings splicing seams
The binding connection of shape reinforcing bar；
5）Wet joint concrete is poured, integrated deck plate is formed, can be come into operation after conserving as required.
The beneficial effects of the invention are as follows：
1, the upper and lower level reinforcing bar that U-shaped reinforcing bar is constituted, can be reliably transmitted moment of flexure and axial tension, make structural connection position
Linear deformation is coordinated, and U-shaped reinforcing bar can construct with solderless, fine the fatigue problem for alleviating reinforcing bar in wet seam；
2, the error range to the pre-buried position of reinforcing bar can be relaxed, it is closely knit to be also conducive to concrete vibrating；
3, U-shaped reinforcing bar can be used as suspension centre, not need additionally to bury lifting lug reinforcing bar；
4, in seam crossing side, vertically V-shaped groove constructs prefabricated bridge, improves the power transmission effect of wet seam；
5, contiguous prefabricated floorings bottom level forms the bottom plate of closure in spelling, realizes wet to the step configuration of stretching
Seam is without bed die rapid construction.
