Description

Technical Field

[0001] The invention relates to the technical field of building decoration, in particular to a split-jointed curved wall structure. Background Art

[0002] In the decoration industry, traditional wall decoration is often decorated with cement, mortar or chemical coatings. The decorative materials may contain harmful or toxic substances, which can easily threaten human health and do not meet the requirements of green environmental protection. In addition, its construction period is long and requires high technical level of workers. Therefore, more and more consumers choose to use wall panels to decorate walls. In existing prefabricated planes, the splicing of wall panels at the corners usually requires cutting of the wall panels, which makes the installation of wall panels at the corners take a long time and reduces the efficiency of construction.

[0003] To this end, the Chinese patent with the publication number "CN220814649U" announced "a connection structure of an assembled flat-joined wall", whose main structure includes an arc-shaped external corner plate installed at the external corner of the wall, decorative panels laid on both sides of the arc-shaped external corner plate, and a skirting installed at the bottom of the arc-shaped external corner plate and the decorative panel; the two side ends of the arc-shaped external corner plate are connected to the decorative panel, and the skirting is buckled with the arc-shaped external corner plate to close the arc-shaped external corner plate and the decorative panel. The connection structure of the assembled flat-joined wall splices the decorative panel with the arc-shaped external corner plate, so that the decorative panel does not need to be cut when it is laid at the external corner of the wall, and then the skirting is installed at the bottom of the arc-shaped external corner plate and the decorative panel by buckling, and the arc-shaped external corner plate and the decorative panel are closed, so that the installation of the assembled flat-joined wall is convenient and fast, saving time and effort, thereby improving construction efficiency and reducing the labor intensity of construction workers.

[0004] However, the curved external angle plate and the decorative panel in the connection structure of the above-mentioned assembled flat-jointed wall are connected by a T-shaped structure. This connection method cannot provide effective stability and is prone to unstable connection and gap phenomenon during installation, resulting in poor connection effect. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1 , Figure 2 and Figure 3 A split-jointed curved wall structure comprises a curved external corner plate 1, a decorative panel 2, a No. 1 strip-shaped wedge-shaped structure 4 arranged on the outside of both ends of the curved external corner plate 1, a bolt fixing hole 3 arranged in the middle of the decorative panel 2, and a No. 2 strip-shaped wedge-shaped structure 5 arranged on the outside of one end of the decorative panel 2. In order to achieve size-limited connection, it is necessary to make the combined structure of the No. 1 strip-shaped wedge-shaped structure 4 and the No. 2 strip-shaped wedge-shaped structure 5 at the connection part form a horizontal isosceles trapezoidal structure. First, the curved external corner plate 1 and the decorative panel 2 are fitted to the part to be decorated according to the installation position, and then threaded holes are drilled on the wall at the corresponding part of the bolt rod 71.

[0027] To improve the connection effect, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, it is necessary to set up a threaded connection mechanism 6, inside which is provided a snap-in limiting plate 66 for snap-in connection of the No. 1 strip wedge structure 4 and the No. 2 strip wedge structure 5, a transverse threaded rod 65 that can make the snap-in limiting plate 66 move in a directional manner around the No. 1 strip wedge structure 4 and the No. 2 strip wedge structure 5 when rotating, and a curved mounting bracket 61 that has a spatial position limiting effect on the transverse threaded rod 65. Directional rotation of the rotating plate 64 will cause the transverse threaded rod 65 to rotate in a directional manner. Due to the connection of the threaded structure, the snap-in limiting plate 66 will move in a directional manner. Since the size of the strip wedge-shaped slot 67 corresponds to the size of the No. 1 strip wedge structure 4 and the No. 2 strip wedge structure 5 in the middle area, the snap-in limiting plate 66 will make the No. 1 strip wedge structure 4 and the No. 2 strip wedge structure 5 more stable at the intersection, thereby improving the connection effect.

[0028] For the specific structure of the threaded connection mechanism 6, please refer to Figure 4 and Figure 5 , including a curved mounting bracket 61 and a snap-in stopper plate 66 fixedly mounted on the outer side of the decorative panel 2, wherein a horizontal No. 1 shaft mounting hole 62 is arranged inside the curved mounting bracket 61, and a rotatable rotating shaft 63 is installed inside the No. 1 shaft mounting hole 62 through a bearing, wherein a rotating plate 64 is fixedly mounted on one end of the rotating shaft 63, and a transverse threaded rod 65 rotating with the rotating shaft 63 is fixedly mounted on the other end of the rotating shaft 63, and the axis of the transverse threaded rod 65 is aligned with the No. 1 strip-shaped wedge structure 4 and The symmetry planes of the second strip-shaped wedge structure 5 are in the same plane, and one end face of the snap-in limiting plate 66 is provided with a strip-shaped wedge-shaped slot 67 with an inwardly concave structure, and the other end face of the snap-in limiting plate 66 is fixedly mounted with an internal thread base 69, and the internal thread base 69 is provided with an internal thread hole 68 connected to the transverse threaded rod 65 through a threaded structure. Specifically, the threaded structure includes an external thread structure provided on the rod body of the transverse threaded rod 65 and an internal thread structure provided in the internal thread hole 68, and the internal thread structure and the external thread structure match each other.

[0029] To achieve a preloaded fixation, see Figure 1 , Figure 2 and Figure 6, it is necessary to set up a pre-tightening fixing structure 7, which is provided with a bolt rod 71 that can be inserted into the wall and fix the decorative panel 2, and a coil spring 76 that can elastically pre-tighten the decorative panel 2. The bolt rod 71 is passed through the bolt fixing hole 3 and aligned with the threaded hole in the wall. The hexagonal head 77 is rotated by a wrench so that the bolt rod 71 is screwed into the threaded hole in the wall. At the same time, the hexagonal head 77 is continuously rotated until the coil spring 76 is in an elastic continuous compression state. Due to the elastic effect of the coil spring 76, the hexagonal head 77 will generate elastic pressure between the decorative panel 2 and the wall, thereby achieving a pre-tightening fixing effect.

[0030] For the specific structure of the pre-tightening fixing structure 7, please refer to Figure 6 , including a bolt rod 71 that can be inserted into the bolt fixing hole 3, the rod body of the bolt rod 71 is provided with an external thread structure for wall installation, the interior of the bolt rod 71 is provided with a component movable cavity 72, one end of the bolt rod 71 is provided with a rod body through hole 73 that connects the external space and one end of the component movable cavity 72, and the bolt rod 71 is provided with a polygonal movable plate 74 that can move axially along the component movable cavity 72 inside the component movable cavity 72. In order to have the transmission function of the rotation effect, it is necessary to make the structural shape of the cross section of the polygonal movable plate 74 and the structural shape of the cross section of the component movable cavity 72 The shapes and appearances are consistent and are all polygonal structures, and the structural dimensions of the cross section of the polygonal movable plate 74 match the structural dimensions of the cross section of the component movable cavity 72. The polygonal movable plate 74 is fixedly installed with an axial movable rod 75 that passes through the rod body through hole 73 at the end facing the rod body through hole 73. The axial movable rod 75 is provided with a coil spring 76 on the periphery of the rod body located inside the component movable cavity 72. The initial length of the coil spring 76 is greater than the axial length of the component movable cavity 72. The axial movable rod 75 is fixedly installed with a hexagonal head 77 at one end located outside the bolt rod 71.

[0031] When in use, the arc-shaped external angle plate 1 and the decorative panel 2 are fitted to the part to be decorated according to the installation position, and then a threaded hole is drilled on the wall at the corresponding part of the bolt rod 71. The rotating plate 64 is rotated in a directional manner, which will cause the transverse threaded rod 65 to rotate in a directional manner. Due to the connection of the threaded structure, the snap-in limiting plate 66 will move in a directional manner. Since the size of the strip wedge-shaped slot 67 corresponds to the size of the No. 1 strip wedge structure 4 and the No. 2 strip wedge structure 5 in the middle area, the snap-in limiting plate 66 will make the No. 1 strip wedge structure 4 and the No. 2 strip wedge structure 5 more stable at the intersection. The bolt rod 71 is passed through the bolt fixing hole 3 and aligned with the threaded hole in the wall. The hexagonal head 77 is turned with a wrench so that the bolt rod 71 is screwed into the threaded hole in the wall. At the same time, the hexagonal head 77 is continuously rotated until the coil spring 76 is in an elastic continuous compression state.
