Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 6 This invention provides a technical solution: a prefabricated building wall panel assembly, comprising a prefabricated wall panel 1, a cylindrical cavity 2, a pull-out bottom groove 3, a suspended top groove 4, an inclined hanging groove 5, a movable roller 6, a high-pressure clearing hole 7, a connecting inner cavity 8, a high-pressure air inlet 9, and a traction hook. The prefabricated wall panel 1 has a cylindrical cavity 2 inside, a pull-out bottom groove 3 at the bottom, and a suspended top groove 4 at the top. A connecting structure is provided inside and outside the cylindrical cavity 2, connecting and fixing the pull-out bottom groove 3 and the suspended top groove 4. An inclined hanging groove 5 is provided on the surface of the pull-out bottom groove 3, and the traction hook can cooperate with the inclined hanging groove 5. A detachable retaining device with an adjustable function is provided on one side of the pull-out bottom groove 3 and the suspended top groove 4. The protective mechanism includes movable rollers 6 on both the upper and lower surfaces of the extraction trough 3. These rollers are evenly distributed in a linear array and can rotate, ensuring rolling contact between the precast wall panel 1 and the upper surface of the extraction trough 3, as well as between the extraction trough 3 and the ground. This makes extraction of the extraction trough 3 easier and more convenient. A high-pressure clearing hole 7 is provided on the lower surface of the extraction trough 3, and these holes are staggered with the movable rollers 6. A connecting inner cavity 8 is provided inside the extraction trough 3, and a high-pressure air inlet 9 is provided on the surface of the extraction trough 3. The high-pressure air inlet 9 is connected to the high-pressure clearing hole 7 through the connecting inner cavity 8. During use, an external high-pressure jet pipe is inserted into the high-pressure air inlet 9 for brief ventilation.

[0026] The connecting structure includes an internal threaded through hole 201, a mating bolt 202, a lower positioning plate 203, a central connecting rod 204, an upper positioning plate 205, a top clear hole 206, a threaded shaft 207, a flat square screw block 208, and a shaft nut 209. The internal threaded through hole 201 is provided through the interior of the bottom groove 3. The mating bolt 202 is spirally installed inside the internal threaded through hole 201. The lower positioning plate 203 is fixedly installed at the upper end of the mating bolt 202. The central connecting rod 204 is coaxially fixed to the upper surface of the lower positioning plate 203. The upper positioning plate 205 is fixedly installed at the upper end of the central connecting rod 204. The upper positioning plate 205 and the lower positioning plate 203 have the same diameter, and the diameters of the upper positioning plate 205 and the lower positioning plate 203 are slightly smaller than the diameter of the cylindrical cavity 2, so that they can be inserted into the interior of the cylindrical cavity 2 and limited inside the cylindrical cavity 2, and can only move axially, but cannot move perpendicular to the axis of the cylindrical cavity 2.

[0027] A top light hole 206 is provided through the surface of the suspended ceiling groove 4. A threaded shaft 207 is fixedly installed at the center of the upper surface of the positioning plate 205. The threaded shaft 207 passes through the top light hole 206. A flat square screw block 208 is fixedly installed at the end of the threaded shaft 207. A shaft nut 209 is screwed on the outside of the threaded shaft 207. The shaft nut 209 is located at the upper part of the suspended ceiling groove 4.

[0028] The detachable protection mechanism includes a receiving slot 301, a gear tongue 302, a gear insertion hole 303, a protective connecting plate 304, and a gear bolt 305. The receiving slot 301 is opened inside the pull-out bottom groove 3, and the gear tongue 302 is inserted into the receiving slot 301.

[0029] The gear tongue plate 302 has a gear insertion hole 303 through it. The gear insertion holes 303 are evenly distributed in a linear array. A protective connecting plate 304 is fixedly installed at the end of the gear tongue plate 302. The gear bolt 305 passes through the extraction bottom groove 3 and the gear insertion hole 303 to fix the gear tongue plate 302.

[0030] The traction hook includes a short shaft 501 for the hanging groove, a U-shaped frame 502 and a traction hook 503. The U-shaped frame 502 is U-shaped. The short shaft 501 for the hanging groove is fixedly installed with the U-shaped frame 502. The short shaft 501 for the hanging groove can be limited and matched with the inclined hanging groove 5. The traction hook 503 is fixedly installed on the surface of the U-shaped frame 502.

[0031] A wall panel protrusion 101 is fixedly provided on one side surface of the precast wall panel 1, and a wall panel groove 102 is vertically provided on the other side surface of the precast wall panel 1. A protective connecting plate 304 wraps the wall panel protrusion 101 inside. A suspension hanging plate 401 is fixedly provided on the upper surface of the suspended ceiling groove 4. A suspension hook hole 402 is provided through the interior of the suspension hanging plate 401. The suspension hook hole 402 is used as... Figure 1As shown, multiple sets can be opened to facilitate stable positioning during the suspension process. The ends of the extraction bottom groove 3 and the suspension top groove 4 are respectively provided with docking grooves 403. The docking grooves 403 are located at the ends of the extraction bottom groove 3 and the suspension top groove 4 away from the protective connecting plate 304. The position and size of the docking grooves 403 correspond to those of the wall panel grooves 102.

[0032] Precast wall panel 1 is made of AAC board, which stands for "autoclaved aerated concrete". Compared with concrete in traditional technology, the dry density of AAC wall panel is generally 550Kg / m3, which is only 1 / 4 of that of concrete, making it lighter; the thermal conductivity is 0.09-0.18W / (MK), which is 1 / 10 of that of ordinary concrete, resulting in better thermal insulation.

[0033] In use, the prefabricated wall panel 1 is installed and fixed with components such as the extraction bottom groove 3 and the suspended top groove 4, as follows: Figure 1 and 2 As shown, the bottom groove 3 and the top groove 4 protect the edges and corners of the precast wall panel 1, and the protective connecting plate 304 adapts to the wall panel protrusion 101 according to the adjustment depth of the stop tongue plate 302, so as to avoid the wall panel protrusion 101 being damaged during transportation and suspension.

[0034] During on-site assembly, if it is to be assembled with the protruding edge 101 of the previous precast wall panel 1, the mating groove 403 can be directly facing the protruding edge 101 of the previous precast wall panel 1 without removing the protective connecting plate 304; if it is to be assembled with the groove 102 of the previous precast wall panel 1, the protective connecting plate 304 needs to be removed first.

[0035] When the protective connecting plate 304 is removed, unscrew the stop bolt 305 and pull out the stop tongue plate 302 directly. Then, use the suspension machine to hook the suspension hook hole 402 and move the precast wall panel 1 so that the wall panel protrusion 101 of the precast wall panel 1 aligns with the wall panel groove 102 of the previous precast wall panel 1. At this time, remove the bottom groove 3 and place it under the precast wall panel 1. This will not affect the assembly of the precast wall panel 1 and can provide contact protection between the precast wall panel 1 and the ground to avoid damage.

[0036] When removing the bottom groove 3, first unscrew the shaft nut 209, remove the suspended top groove 4, and then turn the flat square screw block 208 to make the central connecting rod 204 rotate, thereby causing the mating bolt 202 to rotate out of the internal thread through hole 201. Then, pull out the central connecting rod 204 and other structures. At this time, the bottom groove 3 loses its fixation and can be pulled out horizontally.

[0037] Before the bottom groove 3 is horizontally pulled out, the external high-pressure air pipe is briefly connected to the high-pressure air inlet 9. The high-pressure airflow enters the connecting inner cavity 8 through the high-pressure air inlet 9 and is sprayed out through the high-pressure clearing hole 7. This can blow away stones and other debris on the ground below the moving roller 6, making the rolling of the moving roller 6 smoother when the bottom groove 3 is pulled out, thus making the extraction of the bottom groove 3 easier. Then, the short shaft 501 of the traction hook is hooked into the inclined hanging groove 5. The traction device pulls the traction hook through the traction hanging ring 503 to hold the precast wall panel 1 in place. As the traction device drives, the bottom groove 3 is gradually pulled out from under the precast wall panel 1. When the bottom groove 3 is completely pulled out, the precast wall panel 1 will fall slightly, thus fitting perfectly with the previous precast wall panel 1, completing the assembly.

[0038] The components such as the bottom groove 3, the suspended top groove 4, the connecting structure, and the detachable protective mechanism can be recycled and transported back to the factory by workers to be assembled and installed with a new prefabricated wall panel 1 produced by the factory.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
