Description
Technical field
The utility model belongs to technical field of buildings, more particularly to a kind of connection structure with tongue and groove precast shear wall,
For more high-rise assembled-type houses, it is in the milk and connects instead of traditional precast shear wall sleeve.
Background technique
In more high level assembled-type house building courses, its reinforcing bar of the connection of precast shear wall mostly uses sleeve grouting connection,
Mainly there is following drawback:
Drawback one: using dedicated sleeve and grouting material, complicated construction technique is at high cost for sleeve grouting connection；
Drawback two: for reinforcing bar link position in approximately the same plane, stress is unreasonable, does not also meet the requirement of related specifications；
Drawback three: when precast shear wall vertically connects, the concrete surface of newly-laid concrete and precast shear wall is flat
Face, connection reliability cannot be guaranteed.
Summary of the invention
The purpose of this utility model is to provide a kind of connection structure with tongue and groove precast shear wall, connection structure connections
Band tongue and groove precast shear wall for more high-rise assembled-type houses, be in the milk connection, increase instead of traditional precast shear wall sleeve
The contact area of cast-in-place concrete and precast shear wall, while elongated grout hole is equipped in precast shear wall, grout hole pours
Cast-in-place concrete forms whole collective effect, the reliability of node connection at the concrete and precast shear wall jointing built
It is higher.
It the purpose of this utility model and solves its technical problem underlying and adopts the following technical solutions to realize: a kind of band
The connection structure of tongue and groove precast shear wall, including band tongue and groove precast shear wall up and down, band tongue and groove precast shear wall includes vertical steel
Muscle, horizontal reinforcement, grout hole and tongue and groove, for grout hole between horizontal reinforcement, vertical reinforcement presses grouting except horizontal reinforcement
It is arranged between hole center and grout hole center, tongue and groove is between grout hole；Upper band tongue and groove precast shear wall and lower band tongue and groove are prefabricated
Shear wall is misplaced by grout hole, vertical reinforcement dislocation connects, i.e. cast-in-place concrete is poured into lower tongue and groove by upper grout hole, on
Lower vertical reinforcement is dislocated binding installation.
A kind of connection structure with tongue and groove precast shear wall, in which: grout hole dislocation refers to that grout hole is opposite
Lower tongue and groove.
In use, firstly, factory will with tongue and groove precast shear wall it is prefabricated completion and transport scene to, then in floor position
One piece of band tongue and groove precast shear wall is placed in below floor, another piece of band tongue and groove precast shear wall is placed in above floor, is used
Reliable temporary support is fixed, after having bound vertical reinforcement, so that it may directly pour cast-in-place concrete by grout hole.
The invention key of the utility model is exactly to be: one, simple process does not need special sleeve and grouting material.Two,
The concrete newly poured forms tongue and groove shape, can connect well with precast concrete shear wall, collective effect high reliablity.
Three, the lap position of vertical reinforcing bar is staggered, and reasonable stress and meets related specification requirement.
The utility model has clear advantage and beneficial effect compared with prior art.From the above technical scheme,
The utility model has the following characteristics that
1, it solves in more high-rise assembled-type houses, the high problem of the vertical link cost of precast shear wall is such
Precast shear wall connection type simple process with tongue and groove is not necessarily to special material, can reduce project cost.
2, it solves in more high-rise assembled-type houses, reinforcing bar connection is connected using sleeve grouting when precast shear wall vertically connects
It connects, the problem of reinforcing bar is connected to same plane, and stress is unreasonable and does not meet code requirement.Such precast shear wall with tongue and groove
Connection bar splicing head is staggered, and reasonable stress and meets related specification requirement.
3, it solves in more high-rise assembled-type houses, the contact surface of the concrete of newly-laid concrete and precast shear wall is flat
Face, connection reliability cannot be guaranteed.Such precast shear wall with tongue and groove, can increase cast-in-place concrete and prefabricated shearing
The contact area of wall, while elongated grout hole, the concrete and precast shear wall that grout hole pours are equipped in precast shear wall
Cast-in-place concrete forms whole collective effect at jointing, and the reliability of node connection is higher.
