The structure is positioned between a wall panel 1, a structural beam 2, and a structural column 3. It includes a horizontal connection unit and a vertical connection unit. The vertical connection unit is connected to the horizontal connection unit via a connection unit 6, which is fixed within the wall panel 1. A knob adjustment unit 7 is located below the horizontal and vertical connection units. One end of the knob adjustment unit 7 is fixed inside the wall panel 1, and the other end is located on the outer surface of the wall panel 1. One end of the horizontal connection unit is connected to the structural column 3 via a locking unit. The structural column 3 is connected to the structural beam 2, and the structural beam 2 is connected to the wall panel 1.
[0045] The transverse connecting unit includes a transverse moving plate 4. A snap-fit groove 41 is provided on the upper part of the transverse moving plate 4, and a serrated part is provided on the lower part of the transverse moving plate 4. The serrated part includes multiple alternating protrusions 42 and grooves 43. The lower serrated part is used to cooperate with the driven knob 73. When the driven knob 73 is rotated, it squeezes and drives the transverse moving plate 4 to move left and right.
[0046] The vertical connection unit includes a vertically movable plate 5. A limit key 51 is provided on the upper edge of the vertically movable plate 5, and the limit key 51 is perpendicular to the vertically movable plate 5. An elastic element 52 is also provided at one upper end of the vertically movable plate 5. One end of the elastic element 52 is fixedly connected to the vertically movable plate 5, and the other end of the elastic element 52 is fixedly connected to a baffle 53. The baffle 53 is fixedly installed inside the wall panel 1.
[0047] The connecting unit 6 includes a connecting rod 61, a horizontal sliding groove 62, and a vertical sliding groove 63. The vertical sliding groove 63 is formed on the vertical moving plate 5, and the horizontal sliding groove 62 is formed on the horizontal moving plate 4, with the horizontal sliding groove 62 and the vertical sliding groove 63 arranged perpendicularly. The connecting rod 61 passes through the horizontal sliding groove 62 and the vertical sliding groove 63, and the connecting rod 61 is fixedly mounted on the wall panel 1.
[0048] The knob adjustment unit 7 includes an active knob 71, a cooperating rotation shaft 72, and a driven knob 73. The driven knob 73 is located inside the wall panel 1, below the horizontal moving plate 4 and the vertical moving plate 5. The active knob 71 is located outside the wall panel 1, and the cooperating rotation shaft 72 is located between the active knob 71 and the driven knob 73. Both the active knob 71 and the driven knob 73 include a round handle 741 and a locking block 742 disposed on the round handle 741. The locking block 742 is used to press the vertical moving plate 5 and the horizontal moving plate 4 to move them.
[0049] The locking unit includes a locking head 81, one end of which is connected to one end of the transverse moving plate 4, and the other end of which is connected to the structural column 3. The structural column 3 has several connecting slots 31, and the locking head 81 has several corresponding connecting blocks 82. The connecting blocks 82 and the connecting slots 31 are adapted to achieve the connection between the structural column 3 and the locking head 81.
[0050] Multiple connecting protrusions 21 are provided below the structural beam 2. Multiple connecting grooves 11 are provided at the upper end of the wall panel 1. The connecting grooves 11 and the connecting protrusions 21 are adapted to achieve the connection between the wall panel 1 and the structural beam 2.
[0051] The above-mentioned method for connecting wall panels 1 beams and columns in prefabricated buildings includes the following steps:
[0052] Step S1: Pre-install a horizontal moving plate 4, a vertical moving plate 5, a connecting rod 61, and a driven knob 73 inside the wall panel 1, and install and connect the locking head 81 to the horizontal moving plate 4. The connecting rod 61 passes through the horizontal moving groove and the vertical moving groove and is welded and fixed inside the wall.
[0053] Step S2: Move the wall panel 1 to the preset connection position of the structural column 3, so that the locking head 81 is aligned with the reserved groove 43 inside the column.
[0054] Step S3: Rotate the active knob 71 on the surface of the wall panel 1 to drive the driven knob 73 to rotate. The driven knob 73 presses the vertical moving plate 5, causing the vertical moving plate 5 to move upward and compress the elastic element 52 at its top. The limit key 51 of the vertical moving plate 5 disengages from the snap-fit groove 41 of the horizontal moving plate 4.
[0055] Step S4: Continuously rotate the active knob 71 to make the driven knob 73 continue to rotate, while pressing the transverse moving plate 4 to move to the left, driving the connecting block 82 of the locking head 81 to extend into the connecting groove 31 of the structural column 3, completing the initial docking of the wall panel 1 and the column.
[0056] Step S5: After the driven knob 73 rotates one revolution, the pressure on the vertical moving plate 5 stops. The vertical moving plate 5 moves downward under the action of the elastic element 52. The limit key 51 re-engages into the latching groove 41 of the horizontal moving plate 4, locking the horizontal moving plate 4 and preventing it from shifting.
[0057] Step S6: Align the connecting protrusion 21 of the structural beam 2 with the connecting groove 11 at the upper end of the wall panel 1, and move the structural beam 2 downward to connect the connecting protrusion 21 and the connecting groove 11, thereby achieving rapid locking between the beam and the wall panel 1.
[0058] Step S7: Rotate the knob on the surface of wall panel 1 in the reverse direction to unlock and disassemble. Specifically, this includes: rotating the knob on the surface of wall panel 1 in the reverse direction, releasing the pressure of the driven knob 73 on the vertical moving plate 5 and the horizontal moving plate 4, disengaging the limit key 51 of the vertical moving plate 5 from the snap-fit groove 41 of the horizontal moving plate 4, allowing the horizontal moving plate 4 to reset to the right, and disengaging the locking head 81 from the connecting groove 31 of the structural column 3, thus separating wall panel 1 from the column, and then separating the structural beam 2 from wall panel 1 by reverse translation.
[0059] Therefore, the present invention adopts the above-mentioned connection structure and method for wall panels, beams and columns in prefabricated buildings, which significantly reduces the number of bolts used, greatly improves construction efficiency and reduces time costs, and provides strong technical support for the efficient construction of prefabricated buildings. In addition, the present invention not only simplifies the construction process, but also improves the reliability of component connections, and has broad application prospects.
[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
