Description

Technical Field

[0001] This application relates to the field of building construction, and particularly to an environmentally friendly cement prefabricated and assembled wall panel. Background Art

[0002] When constructing large shopping malls or office buildings, etc., construction workers need to build partition walls between floors to form multiple rooms.

[0003] Currently, the existing methods for building partition walls usually adopt the bricklaying method or the wall panel installation method. The bricklaying method means laying bricks layer by layer from bottom to top between floors, and using materials such as concrete to bond between the bricks. However, with the bricklaying method, it is necessary to wait for the concrete to solidify before the partition wall can be completed, and its construction period is relatively long, thus affecting the overall construction efficiency of the building. The wall panel installation method means directly installing wall panels with the same height as the distance between the upper and lower floors between the upper and lower floors. Each wall panel includes a convex edge and a groove. The convex edge of the wall panel is inserted into the groove of the adjacent floor slab, and then construction workers use a large number of bolts to fix the two adjacent floor slabs. Its operation is relatively cumbersome. However, when it is necessary to remove or replace one damaged wall panel after installation, it is necessary to remove all adjacent wall panels before the wall panel to be replaced can be taken down, which is not convenient for construction workers to remove and replace one damaged wall panel. Summary of the Invention

[0004] In order to improve construction efficiency and facilitate construction workers to remove and replace damaged wall panels, this application provides an environmentally friendly cement prefabricated and assembled wall panel.

[0005] An environmentally friendly cement prefabricated and assembled wall panel provided by this application adopts the following technical solutions:

[0006] An environmentally friendly cement prefabricated and assembled wall panel includes a plurality of wall panel bodies for detachably connecting with the upper and lower floors, a control rod rotatably connected inside the wall panel body, two positioning columns respectively slidably connected to the upper and lower ends of the wall panel body, a connecting mechanism arranged between the control rod and the wall panel body for connecting two adjacent wall panel bodies, a positioning mechanism arranged between the positioning column and the control rod for controlling the connection of the positioning column with the upper and lower floors, and a reinforcement mechanism arranged on one side of the wall panel body for strengthening the connection of two adjacent wall panel bodies;

[0007] Positioning holes adapted to the positioning columns are opened at the upper and lower ends of the wall panel body, the positioning columns slide inside the positioning holes, and card holes corresponding to the positioning columns are opened on the upper and lower floors. One end of the two positioning columns can penetrate the positioning holes and be inserted into the corresponding card holes.

[0008] By adopting the above technical scheme, when constructing the partition wall, the construction workers first open the card hole on the side close to the upper and lower floors, abut the multiple wall panel bodies with the upper and lower floors, then operate the positioning mechanism to fix the position of each wall panel body, then operate the connecting mechanism to connect the two adjacent wall panel bodies, and then operate the reinforcing mechanism to reinforce the connection between the two adjacent wall panel bodies; the positioning mechanism can locate the position of a single wall panel body, and the connection mechanism and the reinforcing mechanism work together to make the connection between the two adjacent wall panel bodies more firmly. At the same time, when one of the wall panel bodies is damaged and needs to be replaced, the construction workers first operate the reinforcing mechanism to release the reinforced state of the two adjacent wall panel bodies, then operate the connecting mechanism to release the connection state of the two adjacent wall panel bodies, and then operate the positioning mechanism to release the fixed position between the wall panel body and the upper and lower floors, so that the wall panel body that needs to be disassembled and replaced can be taken out, and there is no need to dismantle multiple wall panel bodies, so that the installation and disassembly of the wall panel body are more convenient, which is convenient for the construction workers to inspect and repair the wall panel body, and improves the construction efficiency of the construction workers.

[0009] Optionally, the connection mechanism includes a plurality of connection plates slidably connected to one side of the wall panel body in the horizontal direction, two latches hinged at one end of the connection plate, two first springs fixed at the other end of the connection plate, two push-pull plates slidably connected to the upper and lower sides of the connection plate, a second spring fixed between the push-pull plate and the latch, and a control component arranged between the push-pull plate and the wall panel body for driving the push-pull plate to move horizontally;

[0010] A slot corresponding to the tongue is provided on the wall panel body, and a plug-in hole corresponding to the tongue is also provided on the wall panel body. The width of the plug-in hole is smaller than the width of the slot, and the plug-in hole is connected to the slot. Both of the two tongues can be plugged into the corresponding slots through the plug-in holes. Push-pull grooves are provided on the upper and lower sides of the connecting plate along the length direction. The two first springs are always in a stretched state and give the push-pull plate a force close to the wall panel body. The two push-pull plates slide in the corresponding push-pull grooves. One end of the second spring is fixedly connected to the side of the tongue away from its hinge axis, and the other end is fixedly connected to the side of the push-pull plate close to the direction of the hinge axis of the tongue.

[0011] By adopting the above technical solution, when construction workers operate the connecting mechanism to connect two adjacent wall panel bodies, first, the control component drives the push-pull plate to move towards one side of the wall panel bodies that are approaching each other. After one end of the push-pull plate abuts against the side wall of the push-pull groove, continue to move the push-pull plate. The push-pull plate drives the connecting plate to move, and the first spring is further stretched. The connecting plate drives the tongue to move towards the insertion hole side. After the outer side wall of the tongue abuts against the inner side wall of the insertion hole, continue to move the tongue. The end of the tongue away from the card slot rotates towards the side close to the connecting plate, and the second spring is further compressed. When the tongue completely moves into the card slot, the second spring rebounds, causing one end of the tongue to rotate back to the position where it abuts against the inner side wall of the card slot. Then the construction worker releases the control component, and the first spring makes the tongue tightly abut against the inner side wall of the card slot, thus realizing the connection between the tongue and the card slot. When the construction worker needs to disconnect the connection between two adjacent wall panel bodies through the connecting mechanism, first operate the control component to drive the push-pull plate to move away from the connecting plate side. The second spring is stretched, and the second spring drives one end of the tongue to rotate towards the side close to the connecting plate, making the ends of the two tongues away from the connecting plate approach each other. The connecting plate automatically moves away from the card slot side under the pulling force of the first spring, causing the tongue and the connecting plate to contract back into the wall panel body, thus realizing the disconnection of the connection state between two adjacent wall panel bodies; it is convenient for construction workers to disassemble the wall panel body.

[0012] Optionally, the control component includes a control plate slidably connected in the wall panel body, a rack fixed on the control plate, and a gear fixedly sleeved on the control rod.

[0013] The control plate is arranged in the vertical direction. A control groove adapted to the control plate is formed in the wall panel body. The control plate is horizontally slidable in the control groove. The control plate is fixedly connected to a plurality of push-pull plates, and the control plate is perpendicular to the push-pull plates. The rack and the gear are meshed with each other.

[0014] By adopting the above technical solution, when construction workers drive the push-pull plate to move through the control component, first rotate the control rod. The control rod drives the gear to rotate. The gear drives the rack to move horizontally. The rack drives the control plate to move horizontally. The control plate can then drive the push-pull plate to move horizontally. Construction workers can drive the push-pull plate to move by driving the gear to rotate, which is convenient for construction workers to operate.

[0015] Optionally, the ends of the two tongues close to their hinge axes are arranged as horizontal planes, and the two horizontal planes can abut against each other.

[0016] By adopting the above technical solution, when the ends of the two tongues close to the second spring move away from each other, the ends of the two tongues close to their hinge axes can abut against each other, which has the effect of restricting the rotation of the tongue and is not likely to occur the phenomenon that the tongue cannot contract due to excessive rotation angle.

[0017] Optionally, the positioning mechanism includes a chuck fixedly sleeved on one side of the positioning post close to the inner bottom wall of the positioning hole, a third spring fixed between the chuck and the outer bottom wall of the positioning post, and a driving assembly arranged between the chuck and the control rod for driving the chuck to move; the third spring is always in a compressed state and applies a force to the chuck away from the inner bottom wall of the positioning hole.

[0018] By adopting the above technical solution, when the construction worker fixes the position of the wall panel body through the positioning mechanism, first operate the driving assembly to drive the chuck to move towards the inner bottom wall of the positioning hole, the third spring is further compressed, and the chuck can drive the positioning post to move towards the inner bottom wall of the positioning hole. Then the construction worker releases the driving assembly, and the positioning post automatically moves away from the inner bottom wall of the positioning hole under the action of the elastic force of the third spring, so that one end of the positioning post is inserted into the card hole, and the position of the wall panel body can be fixed; after the position of the wall panel body is fixed, it is convenient for the construction worker to install multiple wall panel bodies in sequence, and at the same time it is convenient for the connection and reinforcement operations of multiple wall panel bodies; when it is necessary to release the fixed state of the wall panel body position through the positioning mechanism, the construction worker operates the driving assembly to drive one end of the positioning post out of the card hole, which has the effect of convenient operation.

[0019] Optionally, the driving assembly includes a boss fixedly sleeved on one end of the control rod, a rotating ring rotatably connected in the wall panel body, a fourth spring fixed between the rotating ring and the boss, two driving frames slidably connected in the wall panel body corresponding to the two positioning posts, and two driving rods fixed at one end of the driving frame close to the chuck;

[0020] The boss is arranged in a conical shape, the inclined surface of the cone inclines from the control rod to the rotating ring side, the fourth spring is always in a compressed state and applies a force to the boss away from the rotating ring, the driving frame is a "U" - shaped frame and is arranged vertically, the opening directions of the two "U" - shaped frames are opposite, the chuck is located inside the opening of the "U" - shaped frame, the two driving rods are respectively fixed at both ends of the driving frame, a driving groove adapted to the driving frame is opened in the wall panel body, the driving frame is slidably located in the corresponding driving groove, the driving groove is communicated with the positioning hole, and one end of the driving rod penetrates through the driving groove and abuts against the side of the chuck away from the inner bottom wall of the positioning hole; the driving frame includes a first frame body and a second frame body, the first frame body includes a first cross bar and two first longitudinal bars respectively fixed at both ends of the first cross bar, the second frame body includes a second cross bar and two second longitudinal bars respectively fixed at both ends of the second cross bar, the opening of the first frame body faces upward, the opening of the second frame body faces downward, the first cross bar is located below the second cross bar and below the boss, the second cross bar is located above the boss, and both the first cross bar and the second cross bar abut against the inclined surface of the boss.

[0021] By adopting the above technical solution, when the construction personnel operate the driving assembly to drive the chuck to move, they first press the control rod toward the inner side of the wall panel body, and the control rod can drive the boss to move toward the inner side of the wall panel body, and the fourth spring is further compressed, the boss drives the driving frame to move, the driving frame drives the driving rod to move, and the driving rod can drive the chuck to move. After the construction personnel release the control rod, the boss will automatically rebound due to the elastic force of the fourth spring, and the construction personnel can press the control rod to synchronously realize the movement of the two chucks, which is convenient to operate and improves the work efficiency of the construction personnel.

[0022] Optionally, the reinforcement mechanism includes two reinforcement rods rotatably connected to one side of the wall panel body and a reinforcement plate fixedly mounted on the reinforcement rods; the reinforcement plate is vertically arranged, and the two reinforcement plates are spaced apart from each other in the upper and lower parts; a first reinforcement groove is provided on the side of the wall panel body close to the reinforcement rod, and a second reinforcement groove matching the reinforcement plate is provided on the side of the adjacent wall panel bodies close to each other; the reinforcement plate can be rotated from the first reinforcement groove to the second reinforcement groove.

[0023] By adopting the above technical scheme, when the construction personnel operate the reinforcement mechanism to reinforce the connection state of two adjacent wall panel bodies, they first rotate the reinforcement rod, and the reinforcement rod drives the reinforcement plate to rotate, and the reinforcement plate is rotated to the second reinforcement groove in the adjacent wall panel body; after the reinforcement plate is rotated to the second reinforcement groove, it is in a horizontal state, which has the effect of not easily causing the two adjacent wall panel bodies to be misaligned; conversely, the construction personnel can release the connection reinforcement state of the two adjacent wall panel bodies by rotating the reinforcement rod in the opposite direction. The construction personnel can reinforce and release the connection state of the two adjacent wall panel bodies by rotating the reinforcement rod, and the operation is relatively convenient.

[0024] Optionally, a first magnet group is arranged between the reinforcement plate and the first reinforcement groove, and a second magnet group is arranged between the reinforcement plate and the second reinforcement groove; the first magnet group and the second magnet group each include two magnet blocks.

[0025] By adopting the above technical solution, when the reinforcement plate is located in the first reinforcement groove, the two magnet blocks in the first magnet group attract each other, making it difficult for the reinforcement plate to separate from the first reinforcement groove, and at the same time not easy to interfere with the installation of the two adjacent wall panel bodies; when the reinforcement plate is located in the second reinforcement groove, the two magnet blocks in the second magnet group attract each other, making it difficult for the reinforcement plate to separate from the second reinforcement groove, further reinforcing the connection state of the two adjacent wall panel bodies.

[0026] Optionally, a reinforcement plate is fixedly provided at one end of the reinforcement rod, a sink groove is provided at one side of the wall panel body, and the reinforcement plate is located in the sink groove and rotates.

[0027] By adopting the above technical solution, the reinforcement plate increases the contact area between the human hand and the reinforcement rod, making it more convenient for the construction workers to rotate the reinforcement rod; the construction site is relatively complex, and the sunken groove makes it difficult for the construction workers to accidentally touch the reinforcement rod and cause the release of the reinforcement state. At the same time, the sunken groove facilitates the subsequent operation of the construction workers to paste tiles on the surface of the wallboard body, and it is not easy to interfere with the tiles, which is convenient for the construction workers to construct.

[0028] Optionally, a plurality of sound absorption holes are provided on the wallboard body, and the sound absorption holes are arranged in the vertical direction.

[0029] By adopting the above technical solution, the sound absorption holes can reduce the noise impact from the outside on the house, and at the same time can effectively save the production materials of the wallboard body, reduce the weight of the wallboard body, and reduce the production cost of the wallboard body.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. The construction workers can rotate the control rod to realize the connection and disconnection of two adjacent wallboard bodies, and press the control rod to realize the position fixation and release of the wallboard body with the upper and lower floors. The construction workers only need to operate the rotation and movement of the control rod to realize the position fixation of the wallboard body and the connection of two adjacent wallboard bodies;

[0032] 2. One side of two adjacent wallboard bodies that are close to each other is a plane. When it is necessary to disassemble and replace one of the wallboard bodies, first release the connection and reinforcement state of the two adjacent wallboard bodies, then press the control rod, and the position fixation state of the wallboard body can be released. Then the construction workers can disassemble one wallboard body alone, and it is not necessary to remove the adjacent wallboard body to disassemble and replace one of the wallboard bodies;

[0033] 3. After the reinforcement plate rotates to the second reinforcement groove, the second reinforcement groove has a limiting effect on the reinforcement plate, and it is not easy for two adjacent wallboard bodies to be misaligned, further strengthening the connection between two adjacent wallboard bodies.

Detailed implementation manners

[0042] The following will further elaborate on this application in conjunction with the attached Figure 1-7 drawings.

[0043] The embodiment of this application discloses an environmentally friendly cement prefabricated and assembled wall panel. Referring to Figure 1 and Figure 2 , the assembled wall panel includes a plurality of wall panel bodies 1 arranged between upper and lower floors. A plurality of sound absorption holes 11 are formed in the wall panel body 1. The sound absorption holes 11 are arranged in the vertical direction, and the plurality of sound absorption holes 11 are evenly spaced along the length direction of the wall panel body 1. The sound absorption holes 11 can reduce the noise impact from the outside on the house, and at the same time can effectively save the production materials of the wall panel body 1, reduce the weight of the wall panel body 1, and reduce the production cost of the wall panel body 1. A control rod 2 is rotatably connected inside the wall panel body 1. The control rod 2 is perpendicular to the wall panel body 1. One end of the control rod 2 is fixedly provided with a control knob 21. The control knob 21 is used to increase the contact area between the human hand and the control rod 2, facilitating the construction personnel to operate the control rod 2.

[0044] Referring to Figure 2 and Figure 3The upper and lower ends of the wall panel body 1 are respectively connected with positioning columns 3 for sliding movement. The wall panel body 1 is provided with positioning holes 12 adapted to the positioning columns 3. The positioning columns 3 are located in the positioning holes 12 and slide up and down. The upper and lower floors are provided with clamping holes. One end of the two positioning columns 3 can be retracted into the wall panel body 1 or penetrate the positioning holes 12 and be inserted into the clamping holes. A connecting mechanism 4 is provided between the control rod 2 and the wall panel body 1. The connecting mechanism 4 is used to connect two adjacent wall panel bodies 1. A reinforcing mechanism 5 is also provided on one side of the wall panel body 1. The reinforcing mechanism 5 is used to strengthen the connection between the two adjacent wall panel bodies 1. A positioning mechanism 6 is provided between the positioning column 3 and the control rod 2. The positioning mechanism 6 is used to control the connection between the positioning column 3 and the upper and lower floors.

[0045] When construction workers use assembled wall panels to build partition walls, they first open a card hole on the side where the upper and lower floors are close to each other, then abut multiple wall panel bodies 1 against the upper and lower floors, then operate the positioning mechanism 6 to connect the positioning column 3 with the upper and lower floors, then operate the connecting mechanism 4 to connect two adjacent wall panel bodies 1, and then operate the reinforcement mechanism 5 to reinforce the connection between the two adjacent wall panel bodies 1, and repeat the above process to complete the construction of the partition wall; after the partition wall is built, if one of the wall panel bodies 1 is damaged and needs to be replaced, first operate the reinforcement mechanism 5 to release the reinforcement state of the connection between the two adjacent wall panel bodies 1, then operate the connecting mechanism 4 to disconnect the connection between the two adjacent wall panel bodies 1, and then operate the positioning mechanism 6 to release the connection between the positioning column 3 and the upper and lower floors, and finally the damaged wall panel body 1 can be removed separately and replaced with a new wall panel body 1, and construction workers do not need to remove all wall panel bodies 1 to achieve the removal and replacement of one of the wall panel bodies 1.

[0046] Reference Figure 3 and Figure 4 The connection mechanism 4 includes two connection plates 41 that are slidably connected to one side of the wall panel body 1 in the horizontal direction. The two connection plates 41 are arranged at intervals in the vertical direction. Two latch tongues 42 are hinged at one end of the connection plate 41. One end of the two latch tongues 42 is away from each other and the other end is in contact with each other. The contact point of the two latch tongues 42 is a horizontal plane. A slot 13 corresponding to the latch tongue 42 is provided on the wall panel body 1 at the side away from the latch tongue 42. A plug hole 14 corresponding to the latch tongue 42 is also provided on the wall panel body 1. The plug hole 14 is connected to the slot 13 and the width of the plug hole 14 is smaller than the width of the slot 13. The plug hole 14 and the slot 13 together form a "T"-shaped slot as a whole. Both the two latch tongues 42 can be plugged into the slot 13 through the plug hole 14.

[0047] Reference Figure 3 and Figure 4, a first spring 43 is fixedly provided at one end of the connecting plate 41 away from the tongue 42. The first spring 43 is fixedly connected to both the wall panel body 1. The first spring 43 is always in a stretched state and gives the connecting plate 41 a force close to the wall panel body 1. Push-pull plates 44 are slidably connected to both the upper and lower sides of the connecting plate 41. The push-pull plates 44 are horizontally arranged along the length direction of the connecting plate 41. A push-pull groove 411 adapted to the push-pull plates 44 is formed in the connecting plate 41. The push-pull plates 44 are horizontally slidable in the corresponding push-pull grooves 411, and one end of the push-pull plates 44 always abuts against the inner side wall of the push-pull groove 411 close to the tongue 42. A second spring 45 is fixedly provided between the push-pull plate 44 and the end of the tongue 42 away from its hinge. A control assembly 46 is arranged between the push-pull plate 44 and the wall panel body 1. The control assembly 46 is used to drive the push-pull plate 44 to move horizontally.

[0048] Referring to Figure 3 and Figure 5 , the control assembly 46 includes a control plate 461 slidably connected horizontally in the wall panel body 1. A control groove 15 adapted to the control plate 461 is formed in the wall panel body 1. The control plate 461 is slidable in the control groove 15. The control plate 461 is arranged vertically, and the control plate 461 is fixedly connected to all four push-pull plates 44. At the same time, the control plate 461 is perpendicular to the push-pull plates 44. A rack 462 is fixedly provided on the control plate 461. The rack 462 is arranged horizontally. A gear 463 is fixedly sleeved on the control rod 2. The rack 462 meshes with the gear 463.

[0049] When construction workers operate the connecting mechanism 4 to connect two adjacent wall panel bodies 1, first, rotate the control knob 21. The control knob 21 drives the control rod 2 to rotate. The control rod 2 drives the gear 463 to rotate. The gear 463 drives the rack 462 to move away from the wall panel body 1. The rack 462 drives the control plate 461 to move. The control plate 461 can drive the push-pull plate 44 to move. The push-pull plate 44 drives the connecting plate 41 to move. The first spring 43 is further stretched. The connecting plate 41 drives the tongue 42 to move toward the insertion hole 14. After the outer side wall of the tongue 42 abuts against the inner side wall of the insertion hole 14, continue to move the tongue 42. The end of the tongue 42 away from the card slot 13 rotates toward the side close to the connecting plate 41. The second spring 45 is further compressed. When the tongue 42 is completely moved into the card slot 13, the second spring 45 rebounds, causing one end of the tongue 42 to return to the position where it abuts against the inner side wall of the card slot 13. Then, the construction worker releases the control rod 2. The first spring 43 rebounds, causing the tongue 42 to tightly abut against the inner side wall of the card slot 13, thereby realizing the connection between the tongue 42 and the card slot 13, and further realizing the connection between two adjacent wall panel bodies 1.

[0050] When the construction workers release the connection state between two adjacent wall panel bodies 1, they first rotate the control knob 21 in the reverse direction. The control knob 21 drives the control rod 2 to rotate in the reverse direction. The control rod 2 drives the gear 463 to rotate. The gear 463 drives the rack 462 to move towards the side close to the wall panel body 1, thereby driving the push-pull plate 44 to move away from the connecting plate 41. The second spring 45 is stretched. The second spring 45 drives one end of the tongue 42 to rotate towards the side close to the connecting plate 41, so that the ends of the two tongues 42 away from the connecting plate 41 approach each other. Under the pulling force of the first spring 43, the connecting plate 41 automatically moves away from the card slot 13, so that the tongue 42 and the connecting plate 41 retract into the wall panel body 1, and the connection state between two adjacent wall panel bodies 1 can be released.

[0051] Refer to Figure 3 and Figure 4 As shown in FIGS. 5 and 6, the reinforcement mechanism 5 includes two reinforcement rods 51 rotatably connected to one side of the wall panel body 1. The two reinforcement plates 53 are arranged at intervals along the height direction of the wall panel body 1. The reinforcement rods 51 are arranged along the thickness direction of the wall panel body 1. One end of the reinforcement rod 51 is fixedly provided with a reinforcement disc 52. A sunken groove is formed on one side of the wall panel body 1, and the reinforcement disc 52 is rotatably located in the sunken groove. A reinforcement plate 53 is fixedly sleeved on the reinforcement rod 51. The reinforcement plate 53 is arranged vertically. A first reinforcement groove 16 is formed on one side of the wall panel body 1 close to the reinforcement rod 51. A second reinforcement groove 17 adapted to the reinforcement plate 53 is formed on one side of the adjacent wall panel body 1 close to each other. One end of the reinforcement plate 53 can rotate from the first reinforcement groove 16 into the second reinforcement groove 17. A first magnet group 54 is arranged between the reinforcement plate 53 and the first reinforcement groove 16, and a second magnet group 55 is arranged between the reinforcement plate 53 and the second reinforcement groove 17. Both the first magnet group 54 and the second magnet group 55 include two magnet blocks. The two magnet blocks on the first magnet group 54 are respectively fixedly arranged on the sides of the reinforcement plate 53 and the first reinforcement groove 16 close to each other. The second magnet group 55 is respectively fixedly arranged on the sides of the reinforcement plate 53 and the second reinforcement groove 17 close to each other.

[0052] When the construction personnel operate the reinforcement mechanism 5 to reinforce the connection state of the two adjacent wall panel bodies 1, they first rotate the reinforcement disk 52, the reinforcement disk 52 drives the reinforcement rod 51 to rotate, the reinforcement rod 51 drives the reinforcement plate 53 to rotate, the reinforcement plate 53 rotates to the second reinforcement groove 17 in the adjacent wall panel body 1, and at the same time, the two magnets in the first magnet group 54 separate from each other, and the two magnets in the second magnet group 55 attract each other. The first magnet group 54 makes it difficult for the two adjacent wall panel bodies 1 to interfere during installation, and the second magnet group 55 makes it difficult for the reinforcement plate 53 to separate from the second reinforcement groove 17, further playing the effect of reinforcing the connection state of the two adjacent wall panel bodies 1. On the contrary, the construction personnel rotate the reinforcement disk 52 in the opposite direction, so that the reinforcement plate 53 rotates to the first reinforcement groove 16, and at the same time, the two magnets in the second magnet group 55 move away from each other, so that the two magnets in the first magnet group 54 attract each other, and the connection reinforcement state of the two adjacent wall panel bodies 1 can be released.

[0053] Reference Figure 6 and Figure 7 The positioning mechanism 6 includes a chuck 61 fixedly sleeved on the side of the positioning column 3 close to the inner bottom wall of the positioning hole 12, and a third spring 62 is fixedly arranged between the chuck 61 and the inner bottom wall of the positioning hole 12. The third spring 62 is always in a compressed state and gives the chuck 61 a force away from the inner bottom wall of the positioning hole 12. A driving assembly 63 is arranged between the chuck 61 and the control rod 2, and the driving assembly 63 is used to drive the chuck 61 to move.

[0054] Reference Figure 6 and Figure 7, the driving assembly 63 includes a boss 631 fixedly sleeved on one end of the control rod 2. A rotating ring 632 is arranged on one side of the boss 631. The rotating ring 632 is rotatably connected to the wall panel body 1. The boss 631 is arranged in a conical shape, and the inclined surface of the cone inclines from the control rod 2 to the side of the rotating ring 632. A fourth spring 633 is fixedly arranged between the rotating ring 632 and the boss 631. The fourth spring 633 is always in a compressed state and gives the boss 631 a force away from the rotating ring 632. Two driving frames 634 are slidably connected in the wall panel body 1. A driving groove 18 adapted to the driving frame 634 is opened in the wall panel body 1. The driving groove 18 is communicated with the positioning hole 12. The driving frame 634 slides in the corresponding driving groove 18. The two driving frames 634 correspond to the two positioning columns 3 one by one. The driving frame 634 is a "U"-shaped frame and is arranged vertically. The opening directions of the two "U"-shaped frames are opposite. The chuck 61 is located in the opening of the "U"-shaped frame. The driving frame 634 includes a first frame body 6341 and a second frame body 6342. The first frame body 6341 includes a first cross bar and two first longitudinal bars respectively fixed at both ends of the first cross bar. The second frame body 6342 includes a second cross bar and two second longitudinal bars respectively fixed at both ends of the second cross bar. The opening of the first frame body 6341 faces upward, and the opening of the second frame body 6342 faces downward. The first cross bar is located below the second cross bar and below the boss 631. The second cross bar is located above the boss 631. Both the first cross bar and the second cross bar are in contact with the inclined surface of the boss 631. Driving rods 635 are fixed at both ends of the two first longitudinal bars and the two second longitudinal bars. One end of the driving rod 635 penetrates through the driving groove 18 and abuts against the side of the chuck 61 away from the inner bottom wall of the positioning hole 12.

[0055] When the construction worker operates the positioning mechanism 6 to fix the position of the wall panel body 1, first, press the control rod 2 towards the inner side of the wall panel body 1. The control rod 2 can drive the boss 631 to move towards the inner side of the wall panel body 1. The fourth spring 633 is further compressed. The boss 631 drives the driving frame 634 to move. The driving frame 634 drives the driving rod 635 to move. The driving rod 635 can drive the chuck 61 to move towards the inner bottom wall side of the positioning hole 12. Then, the positioning hole 12 is communicated with the card hole. Release the control rod 2. Due to the elastic force of the fourth spring 633, the boss 631 will automatically rebound. Due to the elastic force of the third spring 62, the positioning column 3 automatically moves towards the side away from the inner bottom wall of the positioning hole 12, so that one end of the positioning column 3 is inserted into the card hole, and the fixation of the position of the wall panel body 1 can be realized; conversely, when the construction worker releases the fixed state of the position of the wall panel body 1, pressing the control rod 2 can retract the positioning column 3 into the interior of the wall panel body 1.

[0056] The implementation principle of a prefabricated floor slab in an embodiment of this application is as follows: When construction workers use prefabricated wall panels to build partition walls, they first dig clamping holes on the sides of adjacent upper and lower floors that are close to each other. Then, they press the control knob 21 to connect the positioning hole 12 with the clamping hole. Next, they release the control rod 2, and insert one end of the positioning column 3 into the clamping hole, thus fixing the position of the wall panel body 1. Subsequently, they abut adjacent wall panel bodies 1. Then, they rotate the control knob 21 to insert two locking tongues 42 into the clamping grooves 13, and releasing the control knob 21 can achieve the connection of two adjacent wall panel bodies 1. Finally, they rotate the reinforcement plate 52 to rotate the reinforcement board 53 into the second reinforcement groove 17 to reinforce the connection state of two adjacent wall panel bodies 1; When one of the wall panel bodies 1 is damaged and needs to be replaced, they first rotate the reinforcement plate 52 to release the reinforcement of the connection state of two adjacent wall panel bodies 1, then rotate the control knob 21 in the reverse direction to release the connection of two adjacent wall panel bodies 1. Subsequently, they press the control knob 21 to release the fixed state of the position between the wall panel body 1 and the upper and lower floors. Finally, they remove the wall panel body 1, without having to remove all adjacent wall panel bodies 1. Workers only need to operate the control knob 21 and the reinforcement plate 52 to install and disassemble the wall panel body 1, thereby improving the construction efficiency of construction workers.

[0057] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application based on this, therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
