In above-mentioned technical proposal, first side relative with second side is provided with the first cooperation through hole on the box body, on
The connection reinforcing bar end of dry wall coordinates through hole through the first of upper plate, and is fixedly connected with being connected box upper plate.
In above-mentioned technical proposal, the aperture of the first cooperation through hole is arranged to being connected reinforcing bar phase inside upper dry wall
Match somebody with somebody, form interference fits；The aperture of the second cooperation through hole is arranged to match with lower dry wall stretching reinforcing bar, forms gap
Coordinate.
In above-mentioned technical proposal, the open-position-side of the connection box is close to overlap installation with the side surface of upper dry wall, or
Passage is provided with by the upper dry wall side for connecting box open-position-side, and passage end is positioned at connection box open-position-side and the other end positioned at prefabricated
The side surface of wall.
In above-mentioned technical proposal, seat slurry is filled between the connection cassette bottom portion and laminated floor slab in-situ layer.
In above-mentioned technical proposal, tamped in the connection box provided with filler, filler is crushed stone concrete or mortar etc.
The material that connection box contacts with extraneous air can be completely cut off.
In above-mentioned technical proposal, the connection reinforcing bar lower end of upper dry wall coordinates through hole through the first of connection box first side,
And be connected nut by screw thread in the end of the connection reinforcing bar, it is lined with pad under nut.
In above-mentioned technical proposal, the first side for connecting box is fixed with branch sleeve, the connection reinforcing bar end of upper dry wall
Making has screw thread, and the connection reinforcing bar end is screwed into the branch sleeve of connection box first side by screw thread and connected admittedly
It is fixed.
Structural principle and remarkable result：
The precast shear wall steel bar connecting joints of the present invention, including connect box and the connection steel being connected with being connected box upper plate
Muscle, the stretching reinforcing bar and upper dry wall, lower dry wall, laminated floor slab being connected with being connected box lower shoe, and connect box and be
A kind of upper plate, lower shoe, left plate, right plate, back side panel closing, the metal box that front side is open-position-side.Metal box is pre-
It is embedded in the bottom of dry wall；After the connection reinforcing bar lower end of upper dry wall passes through the connection reinforcing bar patchhole of metal box upper plate
It is welded and fixed；Or the connection reinforcing bar lower end of upper dry wall through after the upper reinforcing bar patchhole of metal box upper plate with nut,
Pad is connected；Or metal box upper plate is welded and fixed branch sleeve, the connection reinforcing bar lower end of upper dry wall passes through spiral shell
Line screw thread is screwed into the branch sleeve pushed up on metal box fixed.And the stretching reinforcing bar upper end of lower dry wall shows through laminated floor slab
After the stretching reinforcing bar patchhole for pouring layer and metal box lower shoe, the stretching steel bar end passes through screw thread fixing nut and pad
Piece.So, bar connecting is using grouting between steel bar connecting joints of the invention have just abandoned conventional art building element completely
Sleeve or the method and structure of mechanical sleeves connection, overcoming conventional grout sleeve or mechanical sleeves makes two building element structural steel
The shortcomings that muscle docking is difficult, construction is difficult, and use the metal box connection of the present invention to make steel reinforcement abutting joints tolerance big, docking is simple
Easily, efficiency of construction is greatly improved.It is a kind of structures and methods of mechanical connection and the present invention is essentially, so
Not by slurry aging, crushing and grouting is unreal is influenceed, and service life length, structural strength is high, and construction quality is excellent.
