[0002] The characteristic of prefabricated buildings is that a large number of building components are produced and processed by workshops. The main types of components are: exterior wall panels, interior wall panels, composite panels, balconies, air-conditioning panels, stairs, prefabricated beams, prefabricated columns, etc. Among them, lightweight wall panels are becoming more and more widely used in prefabricated buildings.

[0003] The existing patent (publication number: CN220058551U) discloses a lightweight wall panel with core-pulling holes, including a wall panel body, the wall panel body is in the shape of a rectangular parallelepiped, the wall panel body is provided with core-pulling holes, the core-pulling holes are distributed along the length direction of the wall panel body, a steel mesh is provided on one side of the core-pulling holes, the side of the wall panel body is provided with grooves and anti-crack grooves, the grooves and the anti-crack grooves are located on the adjacent two side surfaces of the wall panel body, and a mesh cloth is connected in the anti-crack groove; by setting the core-pulling holes through the wall panel body, the weight of the wall panel is reduced on the basis of ensuring the thermal insulation and sound insulation functions of the wall panel, and the construction difficulty and transportation cost are reduced; the steel mesh is set in the wall panel body, the strength of the lightweight wall panel and the anti-bending performance of the wall panel are improved, and the horizontal cracks in the wall panel body are avoided; the slurry is injected into the groove so that a plurality of lightweight wall panels are solidified to form a whole to improve the vertical crack resistance of the wall panel.

[0004] The technical solution of the above-mentioned public patent solves the problem of weak strength at the connection between two lightweight partition boards. However, during the construction and assembly of the lightweight wall panels, when two grooves are connected to form a closed space, the connecting plate of one of the lightweight wall panels needs to be connected to the connecting plate of the other lightweight wall panel. Since only one surface of the connecting plates is in contact with each other, gaps are likely to occur. When slurry is injected into the groove, the slurry is likely to leak out from the connecting gap between the two connecting plates, which increases the difficulty of construction and assembly and places high requirements on the support and fixation of the two wall panels. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a core-pulling lightweight wall panel, which has the advantages of easy assembly and installation of two lightweight wall panels, and solves the problem that slurry easily leaks out from the butt gap between the two butt plates when injecting slurry into the groove.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a core-pulling lightweight wall panel, comprising a wall panel, wherein the upper end surface of the wall panel is evenly provided with a plurality of vertically arranged core-pulling holes, and the left and right side surfaces of the wall panel are provided with a group of front-to-back symmetrical docking plates, and grooves are formed between each group of the docking plates, and the outer side surface of each of the docking plates forms an anti-crack groove with the side wall of the wall panel, and the rear docking plate of each group of the docking plates is provided with a clamping plate protruding from the side surface away from the wall panel, and the front side surface of the front docking plate of each group of the docking plates is provided with a clamping groove adapted to the clamping plate.

[0007] Through the above scheme, the groove at one end of one wall panel is placed opposite to the groove at one end of the other wall panel, and the two wall panels are supported and fixed so that the two grooves are butted to form a closed space in the circumferential direction, and then slurry is injected into the closed space, and the connection of the two wall panels is completed after the slurry solidifies; the mesh cloth is pasted in the anti-crack groove where the two wall panels are spliced ​​together, and then anti-crack mortar is injected into the anti-crack groove, and the mortar is smoothed so that its surface is flush with the outer side of the wall panel, and the anti-crack mortar is waited for to solidify, thereby improving the vertical anti-crack performance of the wall panel; wherein, the core-pulling hole can improve the thermal insulation and insulation performance of the wall panel sound performance; when in use, the groove at one end of one of the wall panels is placed opposite to the groove at one end of the other wall panel, so that the clamping plate on one of the wall panels cooperates with the clamping groove on the other wall panel, forming an effect of staggered clamping of the two butt joint plates under the cooperation of the clamping plate and the clamping groove, so that the two wall panels are easy to clamp during construction and assembly, and the two wall panels after clamping are easy to fix, the construction is fast, and it is not easy to produce gaps. When slurry is injected into the groove, it is not easy to leak from the butt joint gap between the two butt joint plates, which not only improves the assembly efficiency, but also improves the connection quality of the two wall panels.

[0008] Furthermore, two steel meshes parallel to the front and rear side surfaces of the wall panel are arranged inside the wall panel, and the core-pulling hole is located between the two steel meshes.

[0009] According to the above scheme, by arranging the steel mesh inside the wall panel, the transverse crack resistance of the wall panel can be improved, and the strength can be guaranteed while reducing the weight of the wall panel.

[0010] Furthermore, each of the outer side surfaces of the docking plates is provided with a stepped hole along the left-right direction, and the stepped hole includes a receiving cavity and a plug hole which are interconnected. A guide column is fixedly arranged in the receiving cavity, and a frustum is fixedly arranged at one end of the guide column located in the receiving cavity, and the other end of the guide column extends into the plug hole and is slidably connected with the plug hole in the left-right direction. A limit strip is fixedly arranged on the guide column located in the plug hole, and a limit groove which is matched with the limit strip is arranged on the inner side wall of the plug hole corresponding to the limit strip. The guide column is slidably connected with the plug hole through the limit strip and the limit groove, and an expansion body is sleeved on the guide column located in the receiving cavity, and a threaded hole is arranged on the outer end surface of the guide column along the left-right direction.

[0011] Through the above scheme, when the two guide pillars move closer to each other, the two cones are driven to move closer to each other, so that the two cones squeeze the expansion body through the conical surface, causing the expansion body to expand and squeeze the inner wall of the accommodating cavity, thereby causing the cones to drive the two wall panels to move closer to each other through the expansion body.

[0012] Furthermore, a docking device is provided in the socket of the docking plate with a slot, one end of the docking device is connected to a guide column in one of the wall panels through a threaded hole, and the other end of the docking device is connected to a guide column inside another wall panel through a threaded hole.

[0013] Through the above scheme, when in use, first place one of the wall panels to the set position, and then dock the other wall panel with it. When the two wall panels are docked, the docking devices and guide columns in the two wall panels are respectively connected to the threaded holes of the corresponding guide columns and the corresponding docking devices, and then the docking device can drive the two guide columns to move closer to each other through the threaded holes of the guide columns. The movement of the two guide columns drives the corresponding frustum to move. The movement of the frustum squeezes the expansion body, causing the expansion body to expand and squeeze the inner wall of the accommodating cavity, so that the frustum drives the two wall panels to move closer to each other through the expansion body until the docking plates of the two wall panels are docked together without a gap. At this time, the card plate is also located in the corresponding card slot, thereby achieving the purpose of fixing the two wall panels after docking; there is no need to fix them through a supporting and fixing device; construction efficiency is improved.

[0014] Furthermore, the docking device includes a bidirectional threaded rod, the middle part of which is rotatably connected to two circular plates, the two circular plates are both located in the insertion hole of the docking plate with a slot, and are fixed to the docking plate with a slot through the insertion hole, one end of the bidirectional threaded rod is threadedly connected to the guide column in one of the wall panels through a threaded hole, and the other end of the bidirectional threaded rod is threadedly connected to the guide column in the other wall panel through a threaded hole, and a driving device is also arranged between the two circular plates.

[0015] Through the above scheme, when in use, the bidirectional threaded rod is rotated by the driving device, and the rotation of the bidirectional threaded rod drives the two guide columns to move closer to each other, and then the two guide columns drive the two wall panels to move closer to each other through the expansion body, until the docking plates of the two wall panels are docked together without any gap, and the clamping plate is also located in the corresponding clamping groove at this time, thereby achieving the purpose of fixing the two wall panels after docking.

[0016] Furthermore, the driving device includes a worm wheel fixedly arranged on the bidirectional threaded rod between the two circular plates, and a worm is rotatably connected to the corresponding position of the docking plate and the worm wheel. The worm and the worm wheel are meshed with each other, and the worm extends outward and protrudes from the side of the slot on the docking plate.

[0017] According to the above scheme, the worm gear is driven to rotate by rotating the worm, thereby driving the bidirectional threaded rod to rotate.

[0018] Furthermore, a avoidance groove is provided at a position corresponding to the clamping plate and the worm along the left-right direction, and the width of the avoidance groove is greater than the diameter of the worm.

[0019] Through the above solution, when two wall panels are docked, when the clamping plate enters the clamping slot, the worm will enter the corresponding avoidance slot, so that the clamping plate can smoothly enter the corresponding clamping slot.

[0020] Furthermore, the expansion body includes a base sleeved on the guide column, and spring sheets evenly arranged along the circumference of the base.

[0021] Through the above scheme, when the guide column drives the table to move toward the outside of the wall panel, the table works on each spring leaf through the conical surface, so that each spring leaf deforms and expands outward, squeezing the side wall of the accommodating cavity, thereby achieving the purpose of driving the wall panel to move by moving the guide column toward the outside of the wall panel.

[0022] Furthermore, a section of the threaded hole close to the outer end surface of the guide column is set as a light hole, and the diameter of the light hole is larger than the diameter of the bidirectional threaded rod.

[0023] Through the above scheme, when two wall panels are butted together, one end of the two-way threaded rod will first be inserted into the light hole of the guide column. When all the two-way threaded rods are inserted into the light holes of the corresponding guide columns, the rotation of the worm drives the worm wheel to rotate, and the worm wheel drives the two guide columns to move closer to each other through the two-way threaded rod, thereby making the two wall panels move closer to each other and completing the butt connection of the two wall panels.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] The core-pulling lightweight wall panel is provided with a wall panel, a docking plate, a clamping plate and a clamping groove. When the device is used, two wall panels are docked together so that the grooves of the two wall panels are docked together to form a closed space, which is convenient for pouring slurry into the closed space. When the grooves of the two wall panels are docked, the corresponding docking plates are docked together, and the clamping plate enters the corresponding clamping groove at the same time, so that when the docking plates are docked, a clamping effect is formed through the clamping plate and the clamping groove, so that the two wall panels are easy to clamp during construction and assembly, and the two wall panels after clamping are easy to fix, the construction is quick, and it is not easy to generate gaps. When injecting slurry into the groove, it is not easy to leak from the docking gap between the two docking plates, which not only improves the assembly efficiency, but also improves the connection quality of the two wall panels.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] See also Figure 1 - Fig. 9A core-pulling lightweight wall panel in this embodiment includes a wall panel 1, and a plurality of core-pulling holes 2 are evenly opened on the upper end surface of the wall panel 1 along the height direction. A group of docking plates 3 that are symmetrical front and back are arranged on the left and right sides of the wall panel 1, and grooves 4 are formed between each group of docking plates 3. The outer side surface of each docking plate 3 forms an anti-crack groove 5 with the side wall of the wall panel 1.

[0039] When in use, the groove 4 at one end of one wall panel 1 is placed opposite to the groove 4 at one end of the other wall panel 1, and the two wall panels 1 are supported and fixed so that the two grooves 4 are connected to form a closed space in the circumferential direction, and then slurry is injected into the closed space. After the slurry solidifies, the connection between the two wall panels 1 is completed; the mesh cloth is pasted in the anti-crack groove 5 where the two wall panels 1 are spliced ​​together, and then anti-crack mortar is injected into the anti-crack groove 5, and the mortar is smoothed so that its surface is flush with the outer side of the wall panel 1, and the anti-crack mortar is waited for to solidify, thereby improving the vertical anti-crack performance of the wall panel 1; wherein, the core pulling hole 2 can improve the thermal insulation and sound insulation performance of the wall panel 1.

[0040] In order to improve the transverse crack resistance of the wall panel 1, in the present embodiment, two steel meshes 6 parallel to the front and rear side surfaces of the wall panel 1 are arranged inside the wall panel 1, and the core-pulling hole 2 is located between the two steel meshes 6; by arranging the steel mesh 6 inside the wall panel 1, the transverse crack resistance of the wall panel 1 can be improved, and the strength can be guaranteed while reducing the weight of the wall panel 1.

[0041] During the construction and assembly of the wall panels 1, when two grooves 4 are butted together to form a closed space, the butt joint plate 3 of one wall panel 1 needs to be butted together with the butt joint plate 3 of the other wall panel 1. Since only one surface of the butt joint plates 3 is in contact with each other, gaps are likely to occur. When slurry is injected into the grooves 4, the slurry is likely to leak out from the butt joint gap between the two butt joint plates 3, which increases the difficulty of construction and assembly and places high requirements on the support and fixation of the two wall panels 1.

[0042] In order to solve the above problems, in the present embodiment, the side surface of the rear side docking plate 3 of each group of docking plates 3 away from the wall panel 1 is protruded with a clamping plate 7, and the front side surface of the front side docking plate 3 of each group of docking plates 3 is provided with a clamping groove 8 matched with the clamping plate 7; when in use, the groove 4 at one end of one wall panel 1 is placed opposite to the groove 4 at one end of the other wall panel 1, so that the clamping plate 7 on one wall panel 1 cooperates with the clamping groove 8 on the other wall panel 1, forming an effect of staggered clamping of the two docking plates 3 under the cooperation of the clamping plate 7 and the clamping groove 8, so that the two wall panels 1 are easy to clamp during construction and assembly, and the two wall panels 1 after clamping are easy to fix, the construction is quick, and it is not easy to produce gaps. When injecting slurry into the groove 4, it is not easy to leak from the docking gap between the two docking plates 3, which not only improves the assembly efficiency, but also improves the connection quality of the two wall panels 1.

[0043] During the construction and assembly of the two wall panels 1, the two wall panels 1 need to be butt-joined together, and at the same time, the two butt-joined wall panels 1 need to be fixed together to facilitate the injection of slurry into the groove 4. Therefore, during the construction and assembly of the two wall panels 1, it is also necessary to prepare additional fixing support devices for the two wall panels 1, which increases the difficulty of construction and assembly. At the same time, the fixing support device itself increases the construction cost, and the fixing support device also needs to be transported and handled, which is more troublesome.

[0044] In order to solve the above problems, in this embodiment, each of the outer sides of the docking plate 3 is provided with a stepped hole along the left and right directions, and the stepped hole includes a receiving cavity 9 and a plug hole 10 that are connected to each other. A guide column 11 is fixedly provided in the receiving cavity 9, and a round table 12 is fixedly provided at one end of the guide column 11 located in the receiving cavity 9, and the other end of the guide column 11 extends into the plug hole 10 and is slidably connected to the plug hole 10 in the left and right directions. A limit strip 23 is fixedly provided on the guide column 11 located in the plug hole 10, and is connected to the limit strip 23 with the limit strip 23. A limiting groove matched with the limiting strip 23 is provided on the inner side wall of the socket 10 corresponding to the positioning strip 23, and the guide column 11 is slidably connected with the socket 10 through the limiting strip 23 and the limiting groove. An expansion body is sleeved on the guide column 11 located in the accommodating cavity 9, and a threaded hole 13 is provided on the outer end surface of the guide column 11 along the left and right directions; a docking device is provided in the socket 10 of the docking plate 3 provided with the card slot 8, and one end of the docking device is connected to the guide column 11 in one of the wall panels 1 through the threaded hole 13, and the other end of the docking device is connected to the guide column 11 in one of the wall panels 1 through the threaded hole 13. One end is connected to the guide column 11 inside the other wall panel 1 through a threaded hole 13; when in use, first place one of the wall panels 1 to the set position, and then dock the other wall panel 1 with it. When the two wall panels 1 are docked, the docking devices and guide columns 11 in the two wall panels 1 are respectively connected to the threaded holes 13 of the corresponding guide columns 11 and the corresponding docking devices. Then the docking device can drive the two guide columns 11 to move closer to each other through the threaded holes 13 of the guide columns 11. The movement of the two guide columns 11 drives the corresponding frustum 12 to move. The movement of the frustum 12 squeezes the expansion body, causing the expansion body to expand and squeeze the inner wall of the accommodating cavity 9, so that the frustum 12 drives the two wall panels 1 to move closer to each other through the expansion body until the docking plates 3 of the two wall panels 1 are docked together without a gap. At this time, the clamping plate 7 is also located in the corresponding clamping groove 8, thereby achieving the purpose of fixing the two wall panels 1 after docking. There is no need to fix them through a supporting fixing device. Construction efficiency is improved.

[0045] In this embodiment, the expansion body includes a base 14 mounted on the guide column 11, and spring sheets 15 evenly arranged along the circumference of the base 14. When the guide column 11 drives the table 12 to move toward the outside of the wall panel 1, the table 12 performs work on each spring sheet 15 through the conical surface, so that each spring sheet 15 is deformed and expanded outward, squeezing the side wall of the accommodating cavity 9, thereby achieving the purpose of driving the wall panel 1 to move by moving the guide column 11 toward the outside of the wall panel 1.

[0046] In this embodiment, the docking device includes a bidirectional threaded rod 16, the middle part of which is rotatably connected to two circular plates 17, the two circular plates 17 are both located in the insertion hole 10 of the docking plate 3 with the slot 8, and are fixed to the docking plate 3 with the slot 8 through the insertion hole 10, one end of the bidirectional threaded rod 16 is threadedly connected to the guide column 11 in one of the wall panels 1 through a threaded hole 13, and the other end of the bidirectional threaded rod 16 is threadedly connected to the guide column 11 in the other wall panel 1 through the threaded hole 13, and a driving device is also provided between the two circular plates 17; when in use, the bidirectional threaded rod 16 is rotated by the driving device, and the rotation of the bidirectional threaded rod 16 drives the two guide columns 11 to move closer to each other, and then the two guide columns 11 drive the two wall panels 1 to move closer to each other through the expansion body, until the docking plates 3 of the two wall panels 1 are docked together without a gap, and the card plate 7 is also located in the corresponding card slot 8 at this time, so as to achieve the purpose of fixing the two wall panels 1 after docking.

[0047] In this embodiment, the driving device includes a worm wheel 18 fixedly arranged on the bidirectional threaded rod 16 located between the two circular plates 17, and a worm 19 is rotatably connected to the position corresponding to the docking plate 3 and the worm wheel 18. The worm 19 and the worm wheel 18 are meshed with each other, and the worm 19 extends outward and protrudes from the side of the slot 8 on the docking plate 3; the worm wheel 18 is driven to rotate by rotating the worm 19, thereby driving the bidirectional threaded rod 16 to rotate.

[0048] Since the worm 19 extends outward into the slot 8 of the docking plate 3, when the two wall panels 1 are docked, the worm 19 will interfere with the card plate 7 from entering the corresponding slot 8. In order to solve this problem, in this embodiment, an avoidance groove 20 is opened in the left and right directions at the position corresponding to the card plate 7 and the worm 19; when the two wall panels 1 are docked, when the card plate 7 enters the slot 8, the worm 19 will enter the corresponding avoidance groove 20, so that the card plate 7 can smoothly enter the corresponding slot 8.

[0049] During construction, in order to make it more convenient to connect the two ends of the bidirectional threaded rod 16 with the threaded rod of the guide column 11, in this embodiment, a section of the threaded hole 13 close to the outer end surface of the guide column 11 is set as a light hole 21; when the two wall panels 1 are docked, one end of the bidirectional threaded rod 16 will first be inserted into the light hole 21 of the guide column 11. When all the bidirectional threaded rods 16 are inserted into the corresponding light holes 21 of the guide columns 11, the worm gear 18 is driven to rotate by the rotation of the worm 19. The worm gear 18 drives the two guide columns 11 to move closer to each other through the bidirectional threaded rods 16, thereby making the two wall panels 1 move closer to each other, completing the docking of the two wall panels 1.

[0050] The working principle of the above embodiment is as follows: The construction method of butt-jointing two wall panels 1 is given below:

[0051] 1. First, place a wall panel 1 at the set position, which is the first wall panel 1;

[0052] 2. Then, another wall panel 1 is connected to the first wall panel 1. The other wall panel 1 is the second wall panel 1. When the two wall panels 1 are connected, the bidirectional threaded rod 16 on the first wall panel 1 is inserted into the insertion hole 10 on the second wall panel 1 and into the light hole 21 of the guide column 11; at the same time, the bidirectional threaded rod 16 on the second wall panel 1 is also inserted into the insertion hole 10 on the first wall panel 1 and into the light hole 21 of the guide column 11;

[0053] 3. Rotate the worm 19 so that the worm 19 drives the bidirectional threaded rod 16 to rotate through the worm wheel 18. The rotation of the bidirectional threaded rod 16 makes the two ends of the bidirectional threaded rod 16 cooperate with the threaded holes 13 of the guide column 11 to form a threaded connection with the guide column 11, so that when the bidirectional threaded rod 16 rotates, it drives the corresponding two guide columns 11 to move closer to each other, and then drives the two wall panels 1 to move closer to each other through the guide columns 11, until the docking plates 3 of the two wall panels 1 are docked together without a gap, and at this time the clamping plate 7 is also located in the corresponding clamping groove 8, so that the purpose of fixing the two wall panels 1 after docking is achieved.

[0054] 4. Then pour slurry into the closed space formed by the two butted grooves 4, and after the slurry solidifies, the connection between the two wall panels 1 is completed.

[0055] 5. Then, the mesh cloth is pasted in the anti-crack groove 5 where the two wall panels 1 are spliced ​​together, and anti-crack mortar is injected into the anti-crack groove 5, and the anti-crack mortar is smoothed so that its surface is flush with the wall panel 1, and the mortar is waited for to solidify; thus, the two wall panels 1 are docked and fixed.

[0056] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
