Specifically, taking an example of connecting two beams by an assembled concrete frame node, two ends of the longitudinal ribs 5 are respectively connected with the ends of the two beams through mechanisms such as grouting sleeves. And two ends of the node body 1 are respectively attached to the end surfaces of the two beams, concrete is poured on the periphery of the node body 1, and finally the connection of the two beams is completed.
Optionally, the length of the longitudinal rib 5 is greater than the length of the node body 1, and the longitudinal rib 5 can be connected with a preset mounting hole 6 on the beam or the column. Of course, the end surfaces of the beams or columns connected to the node of the fabricated concrete frame may be provided with grooves, the node body 1 may be embedded in the grooves, and concrete may be filled in the grooves, thereby fixing the node body 1 to the beams or columns.
If the node body 1 is cross-shaped or extends along three directions perpendicular to each other, the fabricated concrete frame node may connect a plurality of beams and two columns at the same time. Accordingly, the mounting holes 6 include horizontal mounting holes 6 extending in the horizontal direction and vertical mounting holes 6 extending in the vertical direction. The assembled concrete frame node is provided with a plurality of longitudinal ribs 5 along the vertical direction and the horizontal direction, the longitudinal ribs 5 arranged along the vertical direction can be used for connecting columns, the longitudinal ribs 5 arranged along the horizontal direction can be used for connecting beams, and the specific connection mode can be referred to above.
In this embodiment, the fabricated concrete frame node includes a node body 1 and a longitudinal rib 5, and two ends of the longitudinal rib 5 can be connected with two beams or two columns respectively. The node body 1 has a mounting hole 6, and the longitudinal ribs 5 are provided in the mounting hole 6. When the longitudinal ribs 5 are connected with the beams or the columns, the node body 1 is positioned between the longitudinal ribs and the beams or the columns, and concrete is poured on the periphery of the node body 1 in the connecting process so that the node body 1 and the beams or the columns connected with the node body form an integral structure. Compared with the prior art, the assembled concrete frame node is connected with the steel bars only through the grouting sleeve, and the strength of the connecting point can be greatly improved.
The assembled concrete frame node mainly bears shearing stress and tensile stress, and in order to improve the strength of the connecting point, the node body 1 is provided with a notch. The mounting hole 6 is positioned in the notch, and the longitudinal rib 5 passes through the mounting hole 6 on the bottom surface of the notch. After the concave gap is formed, concrete can be filled between the side wall of the concave gap and the longitudinal ribs 5, and the more tightly the concrete is filled, the larger the friction force between the concrete and the side wall of the concave gap and between the concrete and the longitudinal ribs 5 is, so that the tensile stress intensity of the assembled concrete frame node is improved.
Alternatively, for convenience of manufacture, the node body 1 is in a cube shape, and as shown in fig. 1, the notch is located at a vertex angle of the node body 1.
