[0045] Hereinafter, specific embodiments of the disclosure will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the disclosure and are not intended to limit the disclosure.

[0046] Fabricated building is a building that is made of building components and accessories such as floor, wall, stairs, balcony, etc. which are processed in the factory, and then assembled and installed on the production workshop or construction site to form the whole building. Fabricated building has many advantages such as quality controllable, high construction efficiency, and environmental protection, etc. Among them, concrete building modules are favored by the majority of owners due to their superior performance in fireproofing, soundproofing and heat insulation. The existing concrete beam-column joint is formed by connecting the components with embedded steel bars on site and then pouring concrete. The steel bars in the beam-column joint area of the concrete frame structure need to be connected and anchored on site after the components are installed in place, and then the concrete pouring work in the beam-column joint area and the composite beam part is carried out.

[0047] The present disclosure provides a prefabricated concrete beam-column joint 1. Referring to FIGS. 1-5, the prefabricated concrete beam-column joint 1 can include a column 20 and a beam assembly 10. The beam assembly 10 includes a beam 11, a linking member 12, and a pulling member 13. The beams 11 are arranged in pairs, and two beams 11 are spaced along the length of the beams 11 and are located at the top of the column 20. The beam 11 has a channel 111 inside, a top surface 112 of the beam 11 has a top hole 11a in communication with the channel 111, and an end surface 113 of the beam 11 has an end hole 11b in communication with the channel 111. The linking member 12 extends along the length of the beam 11, and the two ends of the linking member 12 are located in the channels 111 of the two adjacent beams 11, respectively. The pulling member 13 is located in the channel 111, and one end of the pulling member 13 is connected to the linking member 12, and the other end extends out of the top hole 11a.

[0048] According to the prefabricated concrete beam-column joint 1 of the present disclosure, by arranging the linking member 12 and the pulling member 13 to cooperate with each other, the linking member 12 can be moved into the channels 111 of the two adjacent beams 11, so that the two beams 111 are connected and assembled, which is easy to operate and improves the assembly efficiency.

[0049] Further, the prefabricated concrete beam-column joint 1 can include at least two groups of beam assemblies 10, and the length directions of the beam assemblies 10 of different groups cross each other. For example, in FIG. 1, there are two groups of beam assemblies 10, and the length directions of the two groups of beam assemblies 10 cross each other.

[0050] Referring to FIGS. 3-5, the channel 111 of the beam 11 further includes a connecting pipe 14. The channel 111 can include a first communication section 111a, a second communication section 111b, and a transition section 111c. Specifically, the first communication section 111a extends along the length of the beam 11, and the second communication section 111b extends along the vertical direction. The transition section 111c is in communication with the first communication section 111a and the second communication section 111b, and the transition section 111c is configured as an arc shape to facilitate the passage of the pulling member 13. The outer surface 141 of the connecting pipe 14 is smooth. Alternatively, referring to FIGS. 6 and 7, in order to improve the adhesion between the connecting pipe 24 and the inner wall of the channel 111, the outer surface 241 of the connecting pipe 24 can be configured as a rough surface, for example, the connecting pipe 24 is configured as a corrugated pipe. Specifically, the outer surface 241 of the connecting pipe 24 has a protrusion 242 and / or a recess 243 that is adapted to the inner wall of the channel 111, for example, the outer surface 241 of the connecting pipe 24 has a protrusion 242 and a recess 243 that is adapted to the inner wall of the channel 111 to improve the adhesion between the connecting pipe 24 and the inner wall of the channel. The connecting pipe 24 can be configured as a steel pipe. The linking member 12 can be configured as a reinforcing bar. The outer diameter of the reinforcing bar is less than or equal to the inner diameter of the steel pipe, which facilitates installation. That is, it is convenient to install the linking member 12 into the connecting pipe 14. For example, it is convenient to partially insert the linking member 12 into the connecting pipe 14.

[0051] Referring to FIG. 1 and FIG. 4, a pouring cavity 1a is formed between the top surface 21 of the column 20 and the beam assembly 10. The fabricated concrete beam-column joint 1 further comprises a connecting member 18 which is filled into the pouring cavity 1a to connect the column 20 and the beam assembly 10. In addition, the fabricated concrete beam-column joint 1 further comprises a first reinforcing member 15 which extends in the vertical direction and is connected to the column 20. The first reinforcing member 15 can be pre-buried in the column 20. Alternatively, the column 20 is provided with a mounting hole, and the first reinforcing member 15 is inserted into the mounting hole and then poured and formed. In order to facilitate the installation of other building components such as floors, the first reinforcing member 15 can be configured to protrude upwardly from the connecting member 18.

[0052] It can be understood that the beam 11 has a necessary frame structure. In order to improve the structural strength of the beam 11, the beam assembly 10 further comprises a beam web 17. The frame structure can abut against the inner side of the beam web 17. In order to facilitate the connection with other building components, the beam web 17 is configured to be connected to the beam 11 and protrude upwardly from the beam 11. In order to facilitate the connection of the beam web 17 with other components, the part of the beam web 17 protruding upwardly from the beam 11 is configured as a downwardly open U-shaped. In order to improve the strength of the beam 11 and reduce the bending degree of the beam 11 under stress, the fabricated concrete beam-column joint 1 further comprises a second reinforcing member 16. The second reinforcing member 16 extends along the length direction of the beam 11, and the second reinforcing member 16 is located between the beam web 17 and the top surface of the beam 11.

[0053] A construction method for erecting the aforementioned fabricated concrete beam-column joint 1 is described in detail below. Specifically, the construction method can include the following steps:

[0054] 1) manufacturing the beam 11 and the column 20, and hoisting the column 20 to the designated position;

[0055] 2) connecting one end of the traction member 13 to the adapter member 12, inserting the adapter member 12 connected with one end of the traction member 13 into the channel 111 of one of the beams 11 (i.e. one of the beams), and making the traction member 13 protrude from the top hole 11a of the beam 11. Hoisting the beam 11 with the adapter member 12 to the top of the column 20, and hoisting another beam 11 to the top of the column 20, adjusting the position of the beam 11 so that the two beams 11 are spaced apart and aligned along the length direction of the beams 11; or,

[0056] The traction member 13 is inserted into the channel 111 of one of the beam bodies 11, and the two ends of the traction member 13 are respectively extended out of the top hole 11a and the end hole 11b of the beam body 11. The end of the traction member 13 extended out of the end hole 11b is connected to the adapter member 12. The adapter member 12 is pulled by the traction member 13 so as to partially extend into the channel 111 of the beam body 11. The beam body 11 with the adapter member 12 is hoisted to the top of the column 20, and another beam body 11 is hoisted to the top of the column 20. The positions of the beam bodies 11 are adjusted so that the two beam bodies 11 are spaced apart and aligned along the length direction of the beam bodies 11.

[0057] 3) Another traction member 13 is inserted into the channel 111 of the other beam body 11 which is not connected to the adapter member 12, and the two ends of the traction member 13 are respectively extended out of the top hole 11a and the end hole 11b of the other beam body 11. The end of the traction member 13 extended out of the end hole 11b is connected to the adapter member 12. The end of the traction member 13 extended out of the top hole 11a is pulled so as to make the adapter member 12 enter the channel 111 of the other beam body 11. The traction members 13 at the two ends of the adapter member 12 are continuously pulled so as to make the lengths of the two beam bodies 11 into which the two ends of the adapter member 12 extend equal or approximately equal.

[0058] 4) The end of the traction member 13 extended out of the top hole 11a is tied to the beam body 11 or the beam body web 17. Concrete is poured into the channel 111 through the top hole 11a and into the pouring cavity 1a, so as to realize the connection and molding of the beam body 11 and the column 20.

[0059] It should be noted that for the column-beam joint 1 comprising a plurality of beam body assemblies 10, the steps 2) and 3) can be repeated to place a plurality of beam body assemblies 10 on the top of the column 20, and then pouring is performed. The step numbers are not fixed and unchangeable in the construction method. Some steps in the construction method can be performed in parallel, and the order is not fixed. For example, in step 2), the beam body 11 can be hoisted to the top of the column 20 first, and the position of the beam body 11 is adjusted so that the two beam bodies 11 are spaced apart and aligned along the length direction of the beam bodies 11. Then, one end of the traction member 13 is connected to the adapter member 12, and the end of the adapter member 12 connected with the traction member 13 is inserted into the channel 111 of one of the beam bodies 11, and the traction member 13 is extended out of the top hole 11a of the beam body 11.

[0060] Alternatively, in step 2), the beam body 11 can be hoisted to the top of the column 20 first, and the position of the beam body 11 is adjusted so that the two beam bodies 11 are spaced apart and aligned with each other along the length direction of the beam body 11. Then the traction member 13 is arranged in the channel 111 of one of the beam bodies 11, and the two ends of the traction member 13 are respectively arranged to extend out of the top hole 11a and the end hole 11b of the beam body 11, and the end of the traction member 13 extending out of the end hole 11b is connected to the connecting member 12, and the connecting member 12 is pulled to make the connecting member 12 partially extend into the channel 111 of the beam body 11.

[0061] Alternatively, in step 2), the beam body 11 can be hoisted to the top of the column 20 first, and the position of the beam body 11 is adjusted so that the two beam bodies 11 are spaced apart and aligned with each other along the length direction of the beam body 11. Then the traction member 13 is arranged in the channel 111 of one of the beam bodies 11, and the two ends of the traction member 13 are respectively arranged to extend out of the top hole 11a and the end hole 11b of the beam body 11, and the end of the traction member 13 extending out of the end hole 11b is connected to the connecting member 12, and the connecting member 12 is pulled to make the connecting member 12 partially extend into the channel 111 of the beam body 11.

[0062] Alternatively, in step 2), the beam body 11 can be hoisted to the top of the column 20 first, and the position of the beam body 11 is adjusted so that the two beam bodies 11 are spaced apart and aligned with each other along the length direction of the beam body 11. Then the traction member 13 is arranged in the channel 111 of one of the beam bodies 11, and the two ends of the traction member 13 are respectively arranged to extend out of the top hole 11a and the end hole 11b of the beam body 11, and the end of the traction member 13 extending out of the end hole 11b is connected to the connecting member 12, and the connecting member 12 is pulled to make the connecting member 12 partially extend into the channel 111 of the beam body 11.

[0063] According to the prefabricated concrete beam-column joint 1 of the present disclosure, the connecting relationship between the adjacent beam bodies 11 is easily established by pulling the connecting member 12 along the channel 111 by the traction member 13, and the position of the connecting member 12 in the channel 111 is convenient to adjust, which effectively solves the problem that the beam-column joint is narrow in space and difficult to construct, and avoids the complex layout of the embedded steel bars, and improves the assembly efficiency. Moreover, the traction member 13 can be fixed to the beam body 11 after the traction is completed, and can be formed with the channel 111, and the connecting member 12 can be finally formed with the connecting member, which further improves the overall structural strength of the beam-column joint 1.
