The technical scheme adopted by the invention is further described below with reference to the schematic diagram.
In this embodiment, a precast reinforced concrete column mechanical connection node for connecting an upper column and a lower column of a precast concrete column, comprising: a pair of steel plate positioning sleeve dies 1, a plurality of node reinforcing longitudinal ribs 2 and a plurality of positive and negative wire straight thread sleeves 3; the steel plate positioning sleeve die 1 is provided with a plurality of first round holes and second round holes; the steel plate positioning sleeve die 1 is respectively arranged on the connecting end surfaces of the upper column and the lower column; connecting longitudinal ribs which longitudinally extend continuously and extend towards the connecting end face are arranged in the upper column and the lower column; the extending ends of the connecting longitudinal ribs respectively penetrate through the first round holes; the upper column and the lower column are internally provided with node reinforcing longitudinal ribs 2 which extend longitudinally and locally and extend towards the connecting end face; the extending end of the node reinforcing longitudinal bar 2 passes through the second round hole; the straight thread sleeve 3 of the positive and negative thread is sleeved between the upper and lower corresponding connecting longitudinal ribs and between the node reinforcing longitudinal ribs 2. The invention fully considers the force transmission of the connecting longitudinal bars of the upper column and the lower column and the bending and shearing resistance reinforcement of the joints, and solves the problems of difficult positioning of the steel bars, bending resistance of the joints and weakening of shearing resistance by arranging the steel plate positioning sleeve die 1, the joint compensation longitudinal bars 2 and the positive and negative wire sleeves.
Referring to fig. 1 to 3, a steel plate positioning sleeve mold 1 is in a shape of a 'circle'; the outer side of the steel plate positioning sleeve die 1 is flush with the outer side of the upper column. The plate thickness of the steel plate positioning sleeve die 1 is 1-40 mm, and the edge width is 80-150 mm. When the reinforcement cages of the upper column and the lower column are manufactured, the steel plate positioning sleeve mold 1 is arranged at two ends of the steel plate positioning sleeve mold and tightly props against the templates of the prefabricated columns. The main function of the steel plate positioning die set 1 is to accurately position the column longitudinal ribs, ensure the alignment of the upper column and the lower column connecting longitudinal ribs and the node compensating longitudinal ribs 2, and strengthen the shearing resistance of the node. In other embodiments than the present embodiment, the steel plate positioning sleeve mold 1 is an annular steel plate.
In this embodiment, the node compensating longitudinal bars 2 are spaced apart from the connecting longitudinal bars. The cross-sectional area of the node compensation longitudinal rib 2 is smaller than the cross-sectional area of the connecting longitudinal ribs. The anchoring mode of the node compensation longitudinal bar 2 in the precast column concrete can be straight anchors, bent anchors or mechanical anchors, and the anchoring length is determined according to the design requirement. The section of the node compensation longitudinal bar 2 is determined according to calculation, and is generally 10% -30% of the area of the single-sided longitudinal bar of the section. The length of the node reinforcing longitudinal ribs 2 and the extending ends of the connecting longitudinal ribs is half of the length of the positive and negative wire straight thread sleeve 3. The main function of the node compensation longitudinal rib 2 is to compensate for the reduction in cross section of the longitudinal rib caused by rolling.
In this embodiment, the length of the straight threaded sleeve 3 is taken as the current standard. The positive and negative wire type straight thread sleeve is an I-stage sleeve and is used for connecting the upper column and the lower column and connecting the longitudinal ribs and the node compensation longitudinal ribs 2 so as to transfer the axial tension or compression force of the upper column and the lower column.
