[0024] Example

[0025] See also Figure 1-3 The present invention provides a self-locking mechanism for a prefabricated concrete wall panel node, including a rotating assembly, a force transmission rod 3 and a sliding assembly. The sliding assembly is connected to the rotating assembly through the force transmission rod 3, and the rotating assembly is connected to the sliding assembly through the force transmission rod 3. The movements between them are correlated. The block 5 and the extrusion block 10 installed on one wall panel are used to push the steel cylinder 6 and the slider 2 of another wall panel. When the two wall panels are approaching each other, the sliding assembly is pushed, and the spring 9 is compressed to generate a force opposite to the pressure. After the two wall panels are tightly combined, the sliding assembly is pressed to the bottom, the slot of the rotating assembly is engaged, and the bolt plate 1 of the rotating assembly is attached to the other wall panel. The wall panel connection can be completed by installing the bolts.

[0026] The rotating assembly comprises a steel cylinder 6, the center of the steel cylinder 6 is provided with a hole, a rotating shaft 7 is arranged in the hole, and the radius of the hole is approximately equal to the radius of the rotating shaft 7 plus 0.1 mm.

[0027] A hinge groove 8 is provided on one side of the steel cylinder 6, and an arc-shaped connecting plate 11 is provided on the other side of the steel cylinder 6. Bolt holes 14 are provided at the end of the arc-shaped connecting plate 11. There are six bolt holes 14 for passing bolts. A protrusion 12 is provided near the end of the steel cylinder 6 of the arc-shaped connecting plate 11. The protrusion 12 fits with the wall panel to be assembled to weaken the shear force generated by the displacement of the two wall panels on the bolts. A connecting groove 13 is provided on the wall panel to be assembled. The connecting groove 13 is adapted to the arc-shaped connecting plate 11, and the wall panel is fixed by bolts.

[0028] The sliding assembly includes a slide groove 4 and a slider 2. The slider 2 moves along the slide groove 4, driving the steel cylinder 6 to move. The slider 2 is arranged on the slide groove 4. The arrangement of the slide groove 4 facilitates the fixation of the slider 2. The slide groove 4 is arranged on the wall panel. One end of the slide groove 4 is open, and the other end of the slide groove 4 is connected to the wall panel.

[0029] The slider 2 is provided with a slot, and a hinge slot 8 is provided in the slot. The hinge slot 8 is welded on the slot, and the hinge slot 8 is connected to the force transmission rod 3. The force transmission rod 3 is a lightweight steel rod. Both ends of the force transmission rod 3 are provided with connecting protrusions, and the connecting protrusions are respectively connected to the hinge slot 8 and the steel cylinder 6. The slider 2 and the steel cylinder 6 are connected through the force transmission rod 3 to form a transmission mechanism. The outside of the slider 2 is provided with a spring 9, and the spring 9 is connected to the slider 2 by welding. There are two springs 9, and the spring 9 is used to provide elastic force. The end of the slider 2 is provided with a spring 9 to obtain appropriate elastic force when reaching the self-locking position, provide reasonable buffering during installation, and provide a pop-up effect during disassembly.

[0030] The wall panel to be assembled is provided with a block 5 with a slot, and an extrusion block 10 is provided at the end of the block 5, and the extrusion block 10 is matched with the slider 2. The steel cylinder 6 is provided with a slot 15, and the slot 15 is matched with the block 5.

Two bolt holes are provided on the bolt plate 1, corresponding to the openings of another wall panel. The bolts are installed after the holes are completely aligned.

[0032] Working steps: The extrusion block 10 of the wall panel squeezes the slider 2 to slide in the slide groove 4, driving the movement of the force transmission rod 3, thereby causing the steel cylinder 6 to produce a rotational movement. When the arc-shaped connecting plate 11 of the steel cylinder 6 is about to fit with another wall panel, the slot on the wall panel 5 and the slot opening 15 on the steel cylinder 6 are completely matched, so that the two wall panels form a tight joint state. The bolt plate 1 is rotated to fit with another wall panel to complete the precise alignment of the bolts, and the installation is completed by installing the bolts.

[0033] When disassembling, the bolts are removed, and the elastic force of the spring 9 separates the two wall panels, and the disassembly is completed.

[0034] Therefore, the present invention adopts the above-mentioned self-locking mechanism of the node of the assembled concrete wall panel. The node controls the relative displacement of the slider through the distance between the two wall panels, thereby limiting the rotation of the steel cylinder through the involved movement of the force transmission rod and the fixation of the bayonet. The self-locking structure of the present invention limits the displacement through the movement of the mechanism and plays a fixing role. The wall panel is easy to install and disassemble, the hole position is accurately positioned, and it is firmly fixed. The overall structure is small and light; the node connection method is flexible, and the number of holes and the contact method of the node can be changed according to needs.
