[0027] Example 1
[0028] Reference Figures 1 to 8 , which is the first embodiment of the present invention, and provides a prefabricated swivel node of an assembled component, which includes a prefabricated column 1, including a torsion hole 11 arranged at the top thereof, and a plurality of grouting holes 12 penetratingly arranged on one side of the torsion hole 11;
[0029] The prefabricated beam 2 is arranged on the top of the prefabricated column 1, and includes a protrusion 21 arranged on one side thereof, a T-groove 22 penetrating the upper surface and the side wall of the protrusion 21, and an operating groove 23 arranged on one side of the T-groove 22;
[0030] The precast node N is connected to a plurality of precast beams 2 and precast columns 1 and includes a rotation node 3 and an anchor node 4.
[0031] Furthermore, the shape of the hole opening and the hole bottom of the torsion hole 11 are consistent, and there is a deflection angle between the two.
[0032] Furthermore, the protrusion 21 includes a longitudinal rib groove arranged on one side thereof.
[0033] Furthermore, the rotation node 3 includes a grouting cylinder 31, a guide block 32 arranged at the bottom of the grouting cylinder 31, a grouting groove 33 arranged through one side of the grouting cylinder 31, a positioning plate 34 arranged at the top of the grouting cylinder 31, a plurality of arc grooves 35 arranged through the surface of the positioning plate 34, a positioning column 36 arranged at the top corner of the positioning plate 34, a snap-fit groove 37 arranged through the upper surface of the positioning column 36, a stirrup groove 38 arranged on one side of the positioning column 36, and a hanging buckle 39 arranged around the opening of the grouting cylinder 31.
[0034] Furthermore, the anchor node 4 includes T-blocks 41 arranged around it, a fixing column 42 arranged at the bottom of the anchor node 4, a pin hole 43 penetrating the side wall of the fixing column 42, and a plurality of positioning ribs 44 arranged at the bottom of the fixing column 42.
[0035] Furthermore, the buckle hole formed by the buckle 39 is aligned with the pin hole 43 .
[0036] Furthermore, it also includes a latch member, and the anchor node 4 and the prefabricated column 1 are fixedly connected via the latch member.
[0037] It should be noted that the precast column 1 , the precast beam 2 and the precast node N are precast concrete components produced in a factory.
[0038] The precast column 1 is square, and a number of longitudinal ribs extend upward from its upper end. In this embodiment, the ribs are evenly distributed along the square, totaling ten. A torsion hole 11 is opened in the middle of the upper end surface of the precast column 1. The opening of the torsion hole 11 is regular and multi-deformed. In this embodiment, a square is used. Specifically, the opening of the torsion hole 11 is inclined on the end surface of the precast column 1 until the square at the bottom of the hole is corrected after being twisted downward by about 20°. In addition, two grouting holes 12 distributed up and down are opened on the inner wall of the torsion hole 11.
[0039] Preferably, the precast beam 2 is also square, and an axially extending protrusion 21 is fixed on its end surface, and a completely through T-slot 22 is provided on the upper surface of the protrusion 21, and an operating groove 23 is provided on one side of the T-slot 22, communicating with the T-slot 22, but not completely passing through the precast beam 2. Notches for limiting the longitudinal reinforcement are also provided on both sides of the T-slot 22.
[0040] Preferably, the positioning plate 34 on the rotation node 3 is consistent with the cross-sectional shape of the precast column 1, and the bottom of the positioning plate 34 is completely fitted with the precast column 1. A grouting cylinder 31 is fixed at the bottom of the positioning plate 34. The opening of the grouting cylinder 31 is at the center of the positioning plate 34, and a plurality of through grouting grooves 33 are opened on the side wall of the grouting cylinder 31. In addition, a guide block 32 having the same shape as the opening of the torsion hole 11 is also fixed at the bottom of the grouting cylinder 31.
[0041] Positioning posts 36 are fixed to the four corners of the positioning plate 34. Engagement grooves 37 are provided on the surface of the positioning posts 36 from top to bottom. The engagement grooves 37 are distributed circumferentially with the grouting tube 31 as the center and in the same direction. On the surface of the positioning plate 34, i.e., around the opening of the grouting tube 31, there are four through arc grooves 35, which are also distributed circumferentially with the grouting tube 31 as the center. In addition, a stirrup groove 38 is provided at one corner of the body of the positioning post 36, but the stirrup groove 38 does not penetrate the positioning post 36. Each stirrup groove 38 is distributed circumferentially with the grouting tube 31 as the center and the notches all point to the axis of the grouting tube 31.
[0042] The hanging buckle 39 is fixed around the opening of the grouting tube 31, between the opening of the grouting tube 31 and the arc groove 35, and two hanging buckles 39 facing each other form a pair, and there are two pairs in total.
[0043] It should be noted that when the guide block 32 is located above the torsion hole 11 and aligned with its opening, the longitudinal reinforcements at the four corners are aligned with the incision of the snap-fit groove 37, and the remaining longitudinal reinforcements just pass through the inside of the arc groove 35. When the rotation node 3 moves downward due to its own weight and along the rotation trajectory of the torsion hole 11 until the guide block 32 falls to the bottom of the torsion hole 11, the longitudinal reinforcements at the four corners are buckled into the tail of the snap-fit groove 37. At this time, the longitudinal reinforcements at this position are positioned; the four side walls of the positioning plate 34 are also aligned with the side walls of the prefabricated column 1.
[0044] Preferably, the anchor node 4 is wide at the top and narrow at the bottom. Specifically, the side wall of the anchor node 4 is fixed with circumferentially distributed T-shaped blocks 41, and a fixing column 42 is fixed at the bottom of the anchor node 4. The fixing column 42 is narrow and thin, which can facilitate the passage of the anchor bar at the bottom of the end face of the precast beam 2. There are several positioning bars 44 at the bottom of the fixing column 42, and the ends of the positioning bars 44 are hook-shaped. In addition, two intersecting pin holes 43 are opened on the side wall of the fixing column 42.
[0045] The present invention can select different installation methods according to the site conditions:
[0046] Vertical hoisting: First, hoist and reinforce the prefabricated column 1, and then hoist the rotating node 3 so that the guide block 32 is aligned with the opening of the torsion hole 11. At this time, the longitudinal bars at the four corners are aligned with the incisions of the snap-fit grooves 37, and the remaining longitudinal bars are respectively inserted into the corresponding arc grooves 35. Then lower the rotating node 3, which will rotate along the torsion trajectory of the torsion hole 11 until the guide block 32 completely falls on the bottom of the torsion hole 11. At this time, the side wall of the positioning plate 34 is aligned with the side wall of the prefabricated column 1, and the longitudinal bars on the four corners are all limited.
[0047] Then, the precast beams 2 on each direction of the precast column 1 are hoisted respectively, and two of the longitudinal reinforcements on the upper end of the precast column 1 pass through the reserved notches on the surface of the protrusion 21 to limit the longitudinal reinforcements there. Then, the waist reinforcements on the end of the precast beam 2 are connected using a straight threaded sleeve.
[0048] Next, the anchor node 4 is hoisted so that the T-blocks 41 in four directions fall into the T-slots 22 at the ends of the precast beams 2, and the positioning ribs 44 are also inserted into the grouting tubes 31 to support the anchor node 4 and prevent the opening of the grouting tubes 31 from being blocked. At this point, the connection between the various components is completed.
[0049] Finally, grouting is performed to reinforce the connection node from the grouting hole 12 at the lower part of the side of the precast column 1. After the grouting material overflows from the grouting hole 12 at the upper part of the precast column, the upper grouting hole 12 is sealed and grouting is continued. The grouting material flows into the grouting tube 31 from the torsion hole 11 and overflows until the entire connection node is filled and flush with the groove surface of the precast beam 2. The upper construction personnel observe with the naked eye whether the grouting is full and dense.
[0050] After the grouting material reaches a certain strength, construct the upper reinforcement of the beam, hoist the composite slab, tie the slab surface reinforcement, and pour concrete.
[0051] Horizontal insertion: First, hoist and reinforce the prefabricated column 1, and then hoist the rotating node 3 so that the guide block 32 is aligned with the opening of the torsion hole 11. At this time, the longitudinal bars at the four corners are aligned with the incision of the snap-fit groove 37, and the remaining longitudinal bars are respectively inserted into the corresponding arc grooves 35. Then lower the rotating node 3, which will rotate along the torsion trajectory of the torsion hole 11 until the guide block 32 completely falls on the bottom of the torsion hole 11. At this time, the side wall of the positioning plate 34 is aligned with the side wall of the prefabricated column 1, and the longitudinal bars on the four corners are all limited.
[0052] At the same time, the U-shaped stirrups can be bundled around the longitudinal reinforcement, and the stirrups can be placed inside the stirrup groove 38 . The bundled stirrups need to be tightly arranged and close to the upper wall of the stirrup groove 38 .
[0053] Then the anchor node 4 is hoisted so that the positioning rib 44 is also inserted into the grouting tube 31 to support the anchor node 4 and prevent the opening of the grouting tube 31 from being blocked. At this time, the openings of the two intersecting pin holes 43 are aligned with the four hanging buckles 39. The construction personnel can use the discarded steel bars at the construction site and insert the discarded steel bars into the hanging buckles 39 and the corresponding pin holes 43 at the same time until the discarded steel bars are inserted in all four directions. At this time, the anchor node 4 is fixed.
[0054] Next, the prefabricated beams 2 on all directions of the prefabricated column 1 are hoisted. The lower end surface of the protrusion 21 needs to be slightly higher than the upper end surface of the anchor node 4, and then it is horizontally inserted to the top of the prefabricated column 1 until the reserved grooves on the surface of the protrusion 21 fit two of the longitudinal reinforcements. At this time, the anchor reinforcement on the prefabricated beam 2 just passes through the bottom of the stirrups and can avoid the fixed column 42.
[0055] Then, the precast beams 2 are lowered so that the T-slots 22 are inserted into the T-blocks 41 therein, until all the precast beams 2 are installed.
[0056] Next, the position and tightness of each stirrup are adjusted through the operating groove 23, and the connection work between the various components is completed.
[0057] Finally, grouting is performed to reinforce the connection node from the grouting hole 12 at the lower part of the side of the precast column 1. After the grouting material overflows from the grouting hole 12 at the upper part of the precast column, the upper grouting hole 12 is sealed and grouting is continued. The grouting material flows into the grouting tube 31 from the torsion hole 11 and overflows until the entire connection node is filled and flush with the groove surface of the precast beam 2. The upper construction personnel observe with the naked eye whether the grouting is full and dense.
[0058] After the grouting material reaches a certain strength, construct the upper reinforcement of the beam, hoist the composite slab, tie the slab surface reinforcement, and pour concrete.
[0059] In summary, compared with the traditional construction method, the present invention prefabricates the nodes, and there is no need to add auxiliary components to the nodes. There is no need to set up formwork during the entire process of node construction, which further improves the assembly rate, simplifies the construction process, and facilitates transportation while improving structural stability. In addition, stirrups can be installed without affecting the integrity and stability of the prefabricated nodes, thereby increasing the structural strength. It can also meet the seismic requirements and weld the two opposing anchor bars.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
