Description

Technical Field

[0001] The present application relates to the technical field of building decoration, and in particular to a seamless installation structure for wall panel corners and a wall panel combination structure. Background Art

[0002] In the construction of building projects such as housing construction, the prefabricated construction method has been increasingly widely used due to its significant advantages such as most components being factory-produced, little or no wet work on-site, fast installation speed, little impact on the surrounding environment, and reduction of construction waste.

[0003] For example, the Chinese patent with the publication number CN220620560U discloses a corner wall panel connection structure, which includes a first wall panel and a second wall panel that are perpendicular to each other, and a plurality of first corner connectors; a plurality of first tenon grooves are provided on the first wall panel, and a plurality of second tenon grooves are provided on the second wall panel. The number of the first tenon grooves, the second tenon grooves, and the first corner connectors is the same and they are correspondingly configured. Each first tenon groove is sequentially and spaced apart along the vertical direction on the first wall panel, and each first tenon groove communicates with the corresponding second tenon groove. The first corner connectors are respectively tenoned into the corresponding first tenon grooves and the second tenon grooves. The above structure can achieve the dry-joint construction of the corner wall panel connection structure, and the two wall panels can be fixedly connected to the foundation / structural slab at the same time. Therefore, it has a high construction efficiency. However, a splicing seam will be left at the splicing corner of the first wall panel and the second wall panel, which is not conducive to the subsequent painting construction, and it is easy to crack after the painting construction is completed.

[0004] For example, the Chinese patent with the publication number CN210316299U discloses a prefabricated decoration wall panel structure, which includes a first panel body, an internal corner connector, an external corner connector, and an edge sealing connector. The first panel body is clamped on the internal corner connector, the external corner connector, and the edge sealing connector; a first arc-shaped transition plate is connected to the internal corner connector, a first arc-shaped clamping plate is fixedly connected to the first arc-shaped transition plate, and a second panel body is detachably connected to the first arc-shaped clamping plate. A second arc-shaped transition plate is connected to the external corner connector, a second arc-shaped clamping plate is fixedly connected to the second arc-shaped transition plate, and a third panel body is detachably connected to the second arc-shaped clamping plate. The above structure solves the problem of leaving a splicing seam at the splicing corner of two wall panels. However, the external corner connector body and the outer arc-shaped transition plate are designed in a matching manner. For the requirements of the external corner radian in different projects, it is necessary to re-open the mold, and the reusability is poor and the cost is high. Summary of the Invention

Detailed implementation mode

[0025] The following will Figures 1-5 further describe the present application in detail.

[0026] An embodiment of the present application discloses a wall panel combination structure. Refer to Figure 1 and Figure 2 , the wall panel combination structure includes a first wall panel 80, a second wall panel 90, and a seamless installation structure for the wall panel corner for connecting the first wall panel 80 and the second wall panel 90. Here, the seamless installation structure for the wall panel corner means that there is no seam at the corner where the first wall panel 80 and the second wall panel 90 are connected.

[0027] The seamless installation structure for the wall panel corner includes an elastic external corner plate 10, a first connecting plate 20, a second connecting plate 30, a first clamping plate 40, a second clamping plate 50, and a linear telescopic structure 60. The elastic external corner plate 10 is arranged in a long strip-shaped arc shape. Initially, the elastic external corner plate 10 is a quarter arc plate, and the angle of the elastic external corner plate 10 can be adjusted to a certain extent by applying an external force to adapt to connecting the first wall panel 80 and the second wall panel 90 with different included angles. The first connecting plate 20 is fixed on one side of the elastic external corner plate 10 and extends along the length direction of the elastic external corner plate 10. The length of the first connecting plate 20 is equal to the length of the elastic external corner plate 10, and the first connecting plate 20 is tangent to the elastic external corner plate 10. The second connecting plate 30 is fixed on the other side of the elastic external corner plate 10 and extends along the length direction of the elastic external corner plate 10. The length of the second connecting plate 30 is equal to the length of the elastic external corner plate 10, and the second connecting plate 30 is tangent to the elastic external corner plate 10, that is, the first connecting plate 20 and the second connecting plate 30 are perpendicular to each other initially.

[0028] Furthermore, the elastic external corner plate 10 is made of one of elastic plastic, elastic composite board, and elastic aluminum-plastic board. In some examples, the first connecting plate 20, the second connecting plate 30, and the elastic external corner plate 10 are integrally molded. In other examples, the first connecting plate 20, the second connecting plate 30, and the elastic external corner plate 10 are made separately and then fixed together by means such as welding.

[0029] One side of the first clamping plate 40 is rotatably connected to the first connecting plate 20 near the elastic external corner plate 10 through a first rotating shaft 41, and is slidably connected between a first position and a second position of the first connecting plate 20 along the width direction of the first connecting plate 20. Specifically, a plurality of first long rings 21 are fixed inside the first connecting plate 20 at intervals along the length direction of the elastic external corner plate 10. The first long ring 21 has a third long hole 211, which is the inner hole of the first long ring 21. The first long ring 21 is arranged close to the elastic external corner plate 10 and extends along the width direction of the first connecting plate 20. The first rotating shaft 41 sequentially passes through the first clamping plate 40 and the first long ring 21, and the first rotating shaft 41 is slidably connected to the inner wall of the third long hole 211 along the length direction of the first long ring 21, so that one side of the first clamping plate 40 can rotate relative to the first connecting plate 20 and can also slide relative to the first connecting plate 20 along the width direction of the first connecting plate 20. The first position and the second position of the first connecting plate 20 are respectively the two ends of the third long hole 211.

[0030] One side of the second clamping plate 50 is rotatably connected to the second connecting plate 30 near the elastic external corner plate 10 through a second rotating shaft 51, and is slidably connected between a third position and a fourth position of the second connecting plate 30 along the width direction of the second connecting plate 30. Specifically, a plurality of second long rings 31 are fixed inside the second connecting plate 30 at intervals along the length direction of the elastic external corner plate 10. The second long ring 31 has a fourth long hole 311, which is the inner hole of the second long ring 31. The second long ring 31 is arranged close to the elastic external corner plate 10 and extends along the width direction of the second connecting plate 30. The second rotating shaft 51 sequentially passes through the second clamping plate 50 and the second long ring 31, and the second rotating shaft 51 is slidably connected to the inner wall of the fourth long hole 311 along the length direction of the second long ring 31, so that one side of the second clamping plate 50 can rotate relative to the second connecting plate 30 and can also slide relative to the second connecting plate 30 along the width direction of the second connecting plate 30. The third position and the fourth position of the second connecting plate 30 are respectively the two ends of the fourth long hole 311.

[0031] The first clamping plate 40 and the second clamping plate 50 are movably arranged in a scissor shape through the third rotating shaft 53, so that the first clamping plate 40 and the second connecting plate 30 cooperate to form a first clamping portion 42 for clamping the edge of the first wall panel 80, and the second clamping plate 50 and the first connecting plate 20 cooperate to form a second clamping portion 52 for clamping the edge of the second wall panel 90. Specifically, a first long hole 43 and a second long hole 54 for the third rotating shaft 53 to pass through are respectively arranged in the middle of the first clamping plate 40 and the middle of the second clamping plate 50. The first long hole 43 extends along the width direction of the first clamping plate 40, and the second long hole 54 extends along the width direction of the second clamping plate 50. The third rotating shaft 53 is slidably connected to the first long hole 43 along the width direction of the first clamping plate 40, and the third rotating shaft 53 is slidably connected to the second long hole 54 along the width direction of the second clamping plate 50. The distance from the first rotating shaft 41 to the first long hole 43 is equal to the distance from the second rotating shaft 51 to the second long hole 54.

[0032] Furthermore, the first clamping plate 40 and the second clamping plate 50 are arranged at intervals along the length direction of the elastic external corner plate 10, and the sum of the numbers of the first clamping plate 40 and the second clamping plate 50 is at least three, so that the clamping force of the first clamping portion 42 acts on the first wall panel 80 in a balanced manner, and the clamping force of the second clamping portion 52 acts on the second wall panel 90 in a balanced manner.

[0033] Refer to Figure 2 And Figure 3 , a linear telescopic structure 60, with both ends respectively connected to the concave side of the elastic external corner plate 10 and the third rotating shaft 53, so as to adjust the angle of the elastic external corner plate 10 by changing the distance between the first rotating shaft 41 and the elastic external corner plate 10 through the linear telescopic structure 60 while driving the first clamping portion 42 to clamp the first wall panel 80 and the second clamping portion 52 to clamp the second wall panel 90. Specifically, the linear telescopic structure 60 includes a first screw rod 61, a second screw rod 62 and an internal thread tube 63. One end of the first screw rod 61 is connected to the concave side of the elastic external corner plate 10, one end of the second screw rod 62 is connected to the third rotating shaft 53, and the thread rotation direction of the second screw rod 62 is opposite to that of the first screw rod 61; one end of the internal thread tube 63 is threadedly connected to the other end of the first screw rod 61, and the other end of the internal thread tube 63 is threadedly connected to the other end of the second screw rod 62. When the internal thread tube 63 is rotated, the first screw rod 61 and the second screw rod 62 approach or move away from each other, so as to change the distance between the first rotating shaft 41 and the elastic external corner plate 10 to adjust the angle of the elastic external corner plate 10 to match the included angle between the first wall panel 80 and the second wall panel 90, and at the same time drive the first clamping portion 42 to clamp the first wall panel 80 and the second clamping portion 52 to clamp the second wall panel 90.

[0034] In some examples, a circular ring 64 is fixed to one end of the second screw rod 62. The circular ring 64 of the second screw rod 62 is sleeved on the third rotating shaft 53 and is rotatably connected to the third rotating shaft 53. A circular ring 64 is fixed to one end of the first screw rod 61. A connecting block 11 is fixed at the recess of the elastic external corner plate 10. A connecting shaft 12 extending along the length direction of the elastic external corner plate 10 is fixed to the connecting block 11. The circular ring 64 of the first screw rod 61 is sleeved on the connecting shaft 12 and is rotatably connected to the connecting shaft 12.

[0035] In some examples, one end of the first screw rod 61 is directly fixed at the recess of the elastic external corner plate 10, and one end of the second screw rod 62 is directly fixed on the third rotating shaft 53.

[0036] Furthermore, the first connecting plate 20 and the second connecting plate 30 are symmetrically arranged on both sides of the linear telescopic structure 60. When the first clamping portion 42 clamps the edge of the first wall panel 80, the first clamping plate 40 and the second connecting plate 30 are parallel to each other; when the second clamping portion 52 clamps the edge of the second wall panel 90, the second clamping plate 50 and the first connecting plate 20 are parallel to each other, so that the first clamping portion 42 and the second clamping portion 52 can clamp wall panels of the same thickness simultaneously, that is, the first wall panel 80 and the second wall panel 90 can adopt wall panels of the same specification, and the applicable range is wider.

[0037] Furthermore, the number of the linear telescopic structures 60 is multiple, and the multiple linear telescopic structures 60 are arranged at intervals along the length direction of the elastic external corner plate 10 to drive the elastic external corner plate 10 to deform from multiple nodes in the length direction of the elastic external corner plate 10 to change the angle of the elastic external corner plate 10, so that the deformation of the elastic external corner plate 10 along the length direction is consistent.

[0038] Furthermore, the wall panel corner seamless installation structure further includes a synchronous belt 70. The synchronous belt 70 is sleeved on the outer sides of the multiple linear telescopic structures 60 and is meshed with the internal threaded pipes 63 of the multiple linear telescopic structures 60, so as to facilitate synchronous adjustment of the lengths of the multiple linear telescopic structures 60.

[0039] Furthermore, a plurality of first pressing strips 22 are arranged on the inner wall of the first connecting plate 20 facing the first clamping portion 42. The plurality of first pressing strips 22 are arranged at intervals along the width direction of the first connecting plate 20, and the first pressing strips 22 extend along the length direction of the first connecting plate 20. When the second clamping portion 52 clamps the second wall panel 90, the first pressing strips 22 are pressed into the edge of the second wall panel 90, so that the second wall panel 90 is not easy to slide relative to the second clamping portion 52 along the width direction of the first connecting plate 20, and the firmness of the connection between the second clamping portion 52 and the second wall panel 90 is improved.

[0040] Further, a plurality of second pressing strips 32 are provided on the inner wall of the second connecting plate 30 facing the second clamping portion 52. The plurality of second pressing strips 32 are arranged at intervals along the width direction of the second connecting plate 30, and the second pressing strips 32 extend along the length direction of the second connecting plate 30. When the first clamping portion 42 clamps the first wall panel 80, the second pressing strips 32 are pressed into the edge of the first wall panel 80, so that the first wall panel 80 is not easily slid relative to the first clamping portion 42 along the width direction of the second connecting plate 30, improving the firmness of the connection between the first clamping portion 42 and the first wall panel 80.

[0041] Further, a first embedding groove 81 is provided on the side of the first wall panel 80 facing away from the second wall panel 90. When the first clamping portion 42 clamps the first wall panel 80, a part of the second connecting plate 30 is embedded in the first embedding groove 81 and is adapted to the first embedding groove 81, and the outer surface of the second connecting plate 30 is flush with the outer surface of the first wall panel 80, so that the connection between the second connecting plate 30 and the first wall panel 80 is flat.

[0042] Further, a second embedding groove 91 is provided on the side of the second wall panel 90 facing away from the first wall panel 80. When the second clamping portion 52 clamps the second wall panel 90, a part of the first connecting plate 20 is embedded in the second embedding groove 91 and is adapted to the second embedding groove 91, and the outer surface of the first connecting plate 20 is flush with the outer surface of the second wall panel 90, so that the connection between the first connecting plate 20 and the second wall panel 90 is flat.

[0044] Figure 5 FIG. is a top view of the seamless installation structure at the wall panel corner connecting the first wall panel 80 and the second wall panel 90 with an obtuse included angle. When it is necessary to use the seamless installation structure at the wall panel corner to connect the first wall panel 80 and the second wall panel 90 with an obtuse included angle, first insert the first wall panel 80 into the first clamping portion 42 and the second wall panel 90 into the second clamping portion 52, and rotate the internal thread tube 63 to gradually reduce the length of the linear telescopic structure 60 until, as Figure 4As shown, then rotate the internally threaded tube 63 to further reduce the length of the linear telescopic structure 60 until the included angle between the first wall panel 80 and the second wall panel 90 is adjusted to the desired angle, and then fix the first wall panel 80 and the second wall panel 90 to the wall.
