For example, the lower concrete column 100 is rectangular, the upper end surface of the lower concrete column is square, and each of four corners of the square is provided with a positioning rod, for example, the positioning rod may be an elongated rod-shaped member such as a steel bar.

Specifically, by arranging the positioning rod extending upwards on the lower concrete column 100 located below, the positioning holes 210 are correspondingly formed in the upper concrete column 200, the lower concrete column 100 and the upper concrete column 200 can be fixed through the positioning rod and the positioning holes 210, and the positioning rod can also play a role in aligning and guiding assembly when the upper concrete column 200 is assembled on the lower concrete column 100, so that the alignment efficiency is improved, and the assembly efficiency is improved. 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;

the first engaging surface 323 is fixed on the first connecting piece 322, and is arranged in parallel with the first peripheral surface 321 at intervals, and is provided with a first clamping groove 326;

The first inner surface 324 is fixed to the other end of the first connecting piece 322 and is disposed parallel to and spaced from the first engaging surface 323.

As shown in fig. 4, the second clamping member 420 includes:

A second peripheral surface 421, the outer side of which is fixedly connected with the end surface of the Y-direction concrete beam 410 vertically, and two ends of the inner side along the X-direction are respectively formed with a second tongue-and-groove 425, and the second tongue-and-groove 425 and the first tongue-and-groove 325 can be mutually engaged;

The second engaging surface 423 is fixed on the second connecting piece 422 and is arranged in parallel with the second peripheral surface 421 at intervals, and a second clamping groove 426 is formed on the second engaging surface, and the second clamping groove 426 and the first clamping groove 326 can be engaged up and down;

The second inner surface 424 is fixed to the other end of the second connecting piece 422, and is disposed parallel to and spaced from the second engaging surface 423.

For example, as shown in fig. 5 to 8, the notch of the first clamping groove 326 is upward, the notch of the second clamping groove 426 is correspondingly downward, and when assembling, two X-beam parts 300 with upward notches are relatively positioned on the upper end surface of the lower concrete column 100, as shown in fig. 5; then, two Y-beam portions 400 are inserted between the two X-beam portions 300 with their notches facing downward, and the second clamping grooves 426 are inserted into the corresponding first clamping grooves 326, so that the clamping and positioning between the X-beam portions 300 and the Y-beam portions 400 are very conveniently achieved.

Specifically, as shown in fig. 8, after the X-directional beam portion 300 and the Y-directional beam portion 400 are fastened and positioned, the first tongue-and-groove 325 at two ends of the first peripheral surface 321 and the second tongue-and-groove 425 at two ends of the adjacent second peripheral surface 421 are engaged with each other, so that the two first peripheral surfaces 321 and the two second peripheral surfaces 421 enclose on the upper end surface of the lower concrete column 100 to form a closed pouring frame, and the positioning rods are respectively located at four corners in the pouring frame and extend out of the pouring frame, and in addition, the two first inner peripheral surfaces 324 and the two second inner peripheral surfaces 424 enclose a central frame at the center of the rectangular frame.

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.

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.
