gaps between the ends of the upper concrete column segment 2 and the lower concrete column segment 1 and the column steel sleeve 4 are densely filled with epoxy mortar, and gaps between the ends of the concrete beam segments 3 and the beam steel sleeve 5 are densely filled with epoxy mortar.
As also shown in fig. 1 and 2, preferably, there are two concrete beam segments 31 and 32, which are respectively located at two opposite sides of the column steel jacket 4, and the respective ends of the two concrete beam segments are respectively loosely fitted and sleeved in a beam steel jacket 51 and 52;
the two beam steel sleeves 51 and 52 are provided with beam steel sleeve flanges 511 and 521 at the ends close to the column steel sleeve 4, two opposite side surfaces of the column steel sleeve 4 are provided with a plurality of column steel sleeve holes 41 corresponding to screw holes of the beam steel sleeve flanges 511 and 521, and the two beam steel sleeves 51 and 52 are detachably and fixedly connected through a high-strength bolt 6 penetrating through the column steel sleeve hole 41. As shown in fig. 3.
Preferably, the ends of the upper and lower concrete column sections 2, 1 are provided with through holes 21, 11 for high strength bolts 6 to pass through.
The high-strength bolt 6 penetrates through the through holes 21 and 11 at the end parts of the upper concrete column section 2 and the lower concrete column section 1, so that the left concrete beam section and the right concrete beam section are integrally pulled, and the upper concrete column section and the lower concrete column section are integrally pulled with the left concrete beam section and the right concrete beam section, so that the connection is firmer.
