[0002] Prefabricated concrete structure buildings are industrialized buildings in which the main components are prefabricated in factories, assembled at the construction site, and then connected together through a small amount of cast-in-place work. The steel sleeve grouting connection is an important connection method for the load-bearing steel bars in this structure.

[0003] Through research and analysis, it was found that the prefabricated column sleeve grouting device still has the following shortcomings to a certain extent.

During demoulding, the two half-tubes cannot be separated normally due to the solidification and expansion of the concrete paddle. In addition, the sleeves cannot be quickly connected and fixed. Bolts and nuts need to be installed on them with a wrench for fixing. The operation is cumbersome and complicated. In order to solve the above technical problems, we designed a prefabricated column sleeve grouting connection device. Utility Model Content

By setting the nut 72, an indirect connection is made between the U-shaped plate 71 and the screw rod 73, so that the screw rod 73 can move when it rotates. The inner wall of the nut 72 is threadedly connected to the screw rod 73, and a handle 74 is welded to one end of the screw rod 73. By setting the handle 74, it is convenient to rotate it to drive the screw rod 73 to rotate, so that it is more labor-saving when rotating. The other end of the screw rod 73 is rotatably connected to a butt plate 75 through a bearing. By setting the butt plate 75, the contact area between the screw rod 73 and the connecting plate 5 is increased, thereby improving the fixing effect.

[0025] See also Figure 2 and Figure 3 The separation mechanism 9 includes an L-shaped plate 91. By setting the L-shaped plate 91, a mounting support is provided for the cone rod 92 so that it can move. One end of the L-shaped plate 91 is welded to both sides of the semi-cylinder 2.
