Of course, the setting positions of the positioning rod and the positioning hole 210 may be exchanged, but the positioning rod may be more convenient to be met by the positioning hole 210 during assembly.
In an embodiment of the present application, as shown in fig. 2, a connection plate 210 is connected to the lower end surface of the upper concrete column 200, the positioning hole 220 is formed on the connection plate 210, and a notch 230 is formed on the upper concrete column 200 to expose the positioning hole 220 and provide a space for tightening the bolt 600.
Specifically, the upper concrete column 200 and the lower concrete column 100 may be columnar bodies formed by casting concrete on a reinforcement cage and molding, so that, in order to facilitate the installation of the positioning hole 220, a connection plate 210 is fixed on the lower end surface of the upper concrete column 200, the connection plate 210 may be a steel plate, and the middle portion of the connection plate 210 is fixedly connected with the upper concrete column 200 into a whole, for example, when the upper concrete column 200 is manufactured, the steel plate and the reinforcement cage in the upper concrete column 200 may be welded together, and after casting concrete, the steel plate and the reinforcement cage are fixedly connected into a whole, so that the steel plate and the upper concrete column 200 form a whole.
In addition, the shape and the size of the connecting plate 210 may be the same as those of the lower end surface of the upper concrete column 200, and four corners of the connecting plate 210 are exposed from the notch 230, so that the positioning hole 220 is formed at each corner.
In an embodiment of the present application, as shown in fig. 3, the first clamping member 320 includes:
a first peripheral surface 321, the outer side of which is fixedly connected with the end surface of the X-direction concrete beam 310 vertically, and first rabbets 325 are formed at two ends of the inner side along the Y-direction respectively;

Because the X-direction beam part 300 and the Y-direction beam part 400 are positioned at the core position of the whole beam column node, the connection strength in the horizontal direction is enhanced and the connection strength in the vertical direction is enhanced in the pouring mode, so that the whole beam column node is higher in strength and better in stability.
Meanwhile, the concrete is poured by virtue of the pouring frame formed by the first clamping member 320 and the second clamping member 420, other auxiliary structures are not required to be additionally arranged, the assembly is convenient and quick, and the overall assembly efficiency is ensured.
In addition, due to the arrangement of the structures such as the first outer peripheral surface 321, the first connecting sheet 322, the first clamping surface 323, the first inner peripheral surface 324, the second outer peripheral surface 421, the second connecting sheet 422, the second clamping surface 423 and the second inner peripheral surface 424, a plurality of connecting frameworks are crisscrossed in the whole pouring frame, so that the contact area with concrete is increased, and the pouring frame can be better connected with the concrete after concrete is poured, and has better connection strength; on the other hand, the strength of the part (the assembly surface 500) is improved, so that the overall strength of the beam column joint is higher. It should be emphasized that the above-described arrangement of the center frame further enhances the strength of the connection with the concrete at the center and the strength at the assembly face 500.
