Semi-grouting sleeve assembly of precast beam steel connection of cast-in-place beam column joints and application thereof
The invention discloses a semi-grouting sleeve assembly of a precast beam steel connection of cast-in-place beam column joints and an application thereof. The semi-grouting sleeve assembly comprises asemi-grouting sleeve and an integral nut bolt, wherein the integral nut bolt is connected with the semi-grouting sleeve. The semi-grouting sleeve comprises a straight cylindrical body, one end of thestraight cylindrical body is a threaded end provided with an internal thread, the other end is a grouting end, and the outer end opening of the grouting end is used to insert a horizontally longitudinal rebar of a prefabricated laminated beam. The integral nut bolt includes a body and internal and external threads disposed on the body. The internal threads are used to connect a thread with one end of the horizontally longitudinal rebar of another prefabricated beam. The semi-grouting sleeve assembly replaces an existing full-grouting sleeve with a precast beam steel connection, the length andweight are reduced by nearly half, and the sleeve price is reduced. When the beam steel used for cast-in-place beam column joints are connected, the requirements on the length of a column section arealso correspondingly reduced, thereby avoiding the increase of the length dimension of the column section and the cost is low.
