Description

Technical Field

[0001] The present invention relates to the technical field of wall panels, and in particular to an assembled wall panel mounting strip and an assembled wall panel mounting structure. Background Art

[0002] Many people planning to renovate their home TV wall are generally concerned about how to decorate it, so they can proceed with the installation based on their understanding. They also want to understand the precautions for TV wall renovation to avoid overlooking certain common issues. For example, existing panelized TV walls are constructed from multiple panels. After splicing, a gap is left between the top and the ceiling, and between the bottom and the TV cabinet. The front decorative panel is used to hang the TV. Due to the weight of the TV, hanging it for a long time will exert a force on the decorative panel, which in turn transfers this force to the composite panel, causing the composite panel to bend forward. Furthermore, the numerous expansion bolts used to secure the composite panels to the wall require a large number of expansion tubes and bolts, resulting in a long installation time. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the assembled panels can be made stronger through slot splicing and locking mechanism, and are not easily deformed when carrying a TV, while saving a large number of expansion bolts and facilitating construction.

[0004] The technical solution of the present invention is a prefabricated wall panel installation strip, comprising an upper side strip, a lower side strip, a left side strip and a right side strip, wherein two first slots are respectively opened at both ends of the left side strip and the right side strip, and a first inserting strip is fixed at each end of the surface of the upper side strip, the upper side strip can be fixed to one end of the left side strip and the right side strip at the same time, and when the first inserting strips at both ends of the upper side strip are inserted into the first slots, one end of the left side strip and the right side strip is fixed, and a second inserting strip is fixed at each end of the surface of the lower side strip, the lower side strip can be fixed to the other end of the left side strip and the right side strip at the same time, and when the second inserting strips at both ends of the lower side strip are inserted into the first slots, the other end of the left side strip and the right side strip is fixed, a row of upper pipe plugs is fixed on the surface of the upper side strip along the length direction, the upper pipe plugs are located on the inner sides of the two first inserting strips, and a row of lower pipe plugs is fixed on the surface of the lower side strip along the length direction;

[0005] The assembled wall panel installation strip also includes a decorative panel and a combination panel assembly. The combination panel assembly includes two first combination panels in the shape of a strip and a plurality of second combination panels in the shape of a strip. The plurality of second combination panels in the shape of a strip are spliced ​​together to form a matrix arrangement. The two first combination panels are respectively spliced ​​at the two ends of the second combination panels on the two sides to form a matrix-arranged combination panel assembly. A U-shaped locking cavity is formed from the top of the first combination panel and the second combination panel downward. The decorative panel is fixed to the front side of the combination panel assembly facing the locking cavity to form a decorative effect on the front side of the combination panel assembly while locking the locking cavity. The front side is covered; the upper side strip and the lower side strip are respectively fixed to the upper and lower ends of the combined board assembly to cover the upper and lower ends of the combined board assembly while driving the upper pipe plug and the lower pipe plug into the locking cavity to form an internal tension fixation on the top and bottom ends of the locking cavity; the upper and lower ends of the decorative panel are respectively provided with two second slots on the left and right sides, and the first insertion strip and the second insertion strip are respectively inserted into the first slots at the upper and lower ends of the left and right strips, and also inserted into the second slots to fix the left and right strips to the left and right sides of the combined board assembly, and at the same time fix the decorative panel to the front side of the combined board assembly.

[0006] As a further preference, the width and length of the locking cavity are slightly smaller than the width and length of the upper tube plug and the lower tube plug, the joint surface of the first combination plate and the second combination plate is provided with a rail and a groove, and the joint surface of the first combination plate and the left and right bars is provided with a rail and a groove.

[0007] As a further preference, the rail is serrated, the slot is also serrated, and the serrated shape and size of the rail match the serrated shape and size of the slot.

[0008] As a further preferred embodiment, the left and right bars are tubular profiles, and when the first and second inserts are inserted into the first slots of the left and right bars, the first and second inserts are both received in the tubular profiles of the left and right bars.

[0009] As a further preference, the width dimensions of the left and right side strips are equal to the width dimensions of the upper and lower side strips, the width dimensions of the upper and lower side strips are equal to the sum of the width dimensions of the composite panel assembly and the width dimensions of the decorative panel plus the composite panel assembly, the height dimensions of the left and right side strips are equal to the height dimension of the composite panel assembly, the length dimensions of the upper and lower side strips are equal to the length dimension of the composite panel assembly, and the length dimension of the decorative panel is equal to the length dimension of the composite panel assembly.

[0010] The present invention also provides an assembled wall panel installation structure: it includes the above-mentioned assembled wall panel installation strip and a protrusion installed on the inner surface of the upper pipe plug and the lower pipe plug, the protrusion is in the shape of a long strip, the protrusion is perpendicular to the inner surface of the upper pipe plug and the lower pipe plug, and the end of the protrusion is provided with an arc-shaped extrusion surface. When the upper pipe plug and the lower pipe plug enter the locking cavity of the first combination plate and the second combination plate, the protrusion is driven to extend into the locking cavity synchronously.

[0011] The locking cam is connected to the fixing rod of the upper row through the rotating holes, and the locking cam of the lower row is respectively transferred to the fixing rod of the lower row through the rotating holes. When the decorative plate is fixed to the front side of the composite plate assembly, the locking cam of the upper row is located below the protrusions of the upper row, and the locking cam of the lower row is located above the protrusions of the lower row. A torsion spring is connected between the locking cam and the fixing rod, and the torsion spring limits the two bottom points of the locking cam between the two inner wall surfaces of the locking cavity by elastic action, and reserves a gap between the two inner side surfaces. When the upper pipe plug and the lower pipe plug enter the locking cavity, the protrusion drives the protrusion to squeeze the locking cam using the arc extrusion surface, so that the two high points of the locking cam rotate to be respectively squeezed on the two inner wall surfaces of the locking cavity.

[0012] As a further preference, each first combined plate is provided with a fixing hole at both upper and lower ends.

[0013] The present invention has the following advantages over the prior art: when all the second panels are joined, they are first positioned by means of rails and slots between their joint surfaces. Since the rails and slots are serrated, the positioning area is increased. When all the second panels are joined and then joined to the first panels on either side, the rails and slots are also aligned and aligned. Since the serrated rails and slots are aligned between all the second panels and between the second panels and the first panels, the overlap area between the second panels and between the second panels and the first panels in the width direction is increased, enabling the assembled panel assembly to support the subsequent suspension of the liquid crystal display over a large area in the width direction and resist deformation under load. Furthermore, the first, second, and decorative panels are locked together by upper and lower side bars. After locking, the upper and lower pipe plugs form an outward tensioning support from the inside of the locking cavity between the second and first panels, further enhancing the bearing strength of the second panels. Only one fixing hole for mounting the combined panel assembly on the wall is provided at each of the upper and lower ends of the first combined panel, thereby reducing the number of expansion bolts used during actual construction and facilitating operation.

[0024] The above and other embodiments and advantages of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, Figures 1-9As shown, the assembled wall panel installation strip provided in this embodiment includes an upper side strip 1, a lower side strip 2, a left side strip 3 and a right side strip 4, two first slots 5 are respectively opened at the two ends of the left side strip 3 and the right side strip 4, and a first inserting strip 6 is fixed at each end of the surface of the upper side strip 1, the upper side strip 1 can be fixed to one end of the left side strip 3 and the right side strip 4 at the same time, and when the first inserting strips 6 at both ends of the upper side strip 1 are inserted into the first slots 5, one end of the left side strip 3 and the right side strip 4 is fixed, and a second inserting strip 7 is fixed at each end of the surface of the lower side strip 2, the lower side strip 2 can be fixed to the other end of the left side strip 3 and the right side strip 4 at the same time, and when the second inserting strips 7 at both ends of the lower side strip 2 are inserted into the first slots 5, the other end of the left side strip 3 and the right side strip 4 is fixed, a row of upper pipe plugs 8 are fixed on the surface of the upper side strip 1 along the length direction, the upper pipe plugs 8 are located on the inner sides of the two first inserting strips 6, and a row of lower pipe plugs 9 are fixed on the surface of the lower side strip 2 along the length direction;

[0026] The assembled wall panel installation strip also includes a decorative panel 11 and a combination panel assembly 12. The combination panel assembly 12 includes two first combination panels 121 in the shape of a strip and a plurality of second combination panels 122 in the shape of a strip. The plurality of second combination panels 122 in the shape of a strip are spliced ​​together to form a matrix arrangement. The two first combination panels 121 are respectively spliced ​​at the two ends of the second combination panels 122 on the two sides, together forming a matrix-arranged combination panel assembly 12. A U-shaped locking cavity 13 is formed from the top of the first combination panel 121 and the second combination panel 122 downward. The decorative panel 11 is fixed to the front side of the combination panel assembly 12 facing the locking cavity 13, so as to form a decorative effect on the front side of the combination panel assembly 12 while locking it. The front side of the cavity 13 is covered; the upper side strip 1 and the lower side strip 2 are respectively fixed to the upper and lower ends of the combined board assembly 12, so as to cover the upper and lower ends of the combined board assembly 12, and at the same time, the upper pipe plug 8 and the lower pipe plug 9 are driven into the locking cavity 13, and the top and bottom ends of the locking cavity 13 are internally tensioned and fixed; the upper and lower ends of the decorative panel 11 are respectively provided with two left and right second slots 111, and the first insertion strip 6 and the second insertion strip 7 are respectively inserted into the first slots 5 at the upper and lower ends of the left strip 3 and the right strip 4, and are also inserted into the second slots 111 to fix the left and right strips 3 and 4 to the left and right sides of the combined board assembly 12, and at the same time fix the decorative panel 11 to the front side of the combined board assembly 12.

[0027] During construction, all the second composite panels 122 are spliced ​​together, and then the first composite panels 121 on the two sides are spliced ​​to the outside of the second composite panels 122 on the two sides to complete the assembly of the composite panel assembly 12. Then, the left strip 3 is spliced ​​to the outside of the first composite panel 121 on the left, and the right strip 4 is spliced ​​to the outside of the first composite panel 121 on the right. Then, the decorative panel 11 is fixed to the front side of the composite panel assembly 12. Finally, the upper strip 1 is buckled to the top of the composite panel assembly 12, the lower strip 2 is buckled to the bottom of the composite panel assembly 12, and the upper strip 1 is buckled to the top of the composite panel assembly 12. When the upper and lower side bars 2 are buckled on the bottom of the combined board assembly 12, the second inserting strips 7 at both ends are respectively inserted into the first slots 5 at the upper and lower ends of the left and right side bars 3 and 4. At the same time, the second inserting strips 7 are also inserted into the second slots 111 on both sides of the bottom end of the decorative board 11. The combined board assembly 12 obtained by splicing the above components at both ends of the upper and lower side bars 1 is fixed, and together constitutes Figure 1 or Figure 2 As shown.

[0028] The top and bottom panels 12 are connected by a plurality of threaded holes 16, 17 and 18. The top and bottom panels 12 are connected by a plurality of threaded holes 16, 17 and 18. The top and bottom panels 12 are connected by a plurality of threaded holes 16, 17 and 18.

[0029] In this embodiment, the width and length of the locking cavity 13 are slightly smaller than the width and length of the upper pipe plug 8 and the lower pipe plug 9. The joint surface of the first assembly plate 121 and the second assembly plate 122 is provided with a rail 14 and a groove 15. The joint surface of the first assembly plate 121 and the left and right bars 3 and 4 is provided with a rail 14 and a groove 15. Figure 3 、 Figure 6 as well as Figure 7As shown, the rail 14 is serrated, and the slot 15 is also serrated. The serrated shape and size of the rail 14 match the serrated shape and size of the slot 15, that is, when all the second combination plates 122 are spliced ​​together, the rail 14 and the slot 15 between their splicing surfaces are engaged to achieve positioning. Since the rail 14 and the slot 15 are serrated, the positioning area is increased. When all the second combination plates 122 are spliced ​​and then spliced ​​with the first combination plates 121 on both sides, the rail 14 and the slot 15 between them are also engaged. The positioning is achieved by docking. Since the mating surfaces between all the second combination plates 122 and between the second combination plates 122 and the first combination plates 121 are docked using serrated rails 14 and slots 15, the overlapping areas in the width direction between the second combination plates 122 and between the second combination plates 122 and the first combination plates 121 are increased, so that the combined combination plate assembly 12 can jointly bear the subsequent suspension of the liquid crystal display over a large area in the width direction and is not easily deformed when bearing gravity. Finally, the upper and lower side bars 1 and 2 lock the first and second assembly panels 121, 122, and decorative panel 11 together. After locking, the upper and lower pipe plugs 8 and 9 create an outward tensioning support from within the locking cavity 13 of the second assembly panel 122 and the first assembly panel 121. This tension is generated in the locking cavity 13 and transmitted between the first and second assembly panels 121, as well as between adjacent second assembly panels 122. Together, these provide longitudinal strength support for the assembly 12, ensuring high longitudinal strength. Furthermore, the outer fixing forces of the upper and lower side bars 1 and 2, as well as the left and right side bars 3 and 4, enhance strength and prevent deformation.

[0030] The left and right rails 3 and 4 are tubular profiles. When the first and second inserts 6 and 7 are inserted into the first slots 5 of the left and right rails 3 and 4, they are both received within the tubular profiles of the left and right rails 3 and 4. The width of the left and right rails 3 and 4 is equal to the width of the upper and lower rails 1 and 2. The width of the upper and lower rails 1 and 2 is equal to the sum of the width of the composite panel assembly 12 and the width of the decorative panel 11 plus the composite panel assembly 12. The height of the left and right rails 3 and 4 is equal to the height of the composite panel assembly 12. The length of the upper and lower rails 1 and 2 is equal to the length of the composite panel assembly 12. The length of the decorative panel 11 is equal to the length of the composite panel assembly 12. The outer periphery of the composite panel assembly 12, which is composed of the upper side strip 1, the lower side strip 2, the left side strip 3, the right side strip 4, the second composite panel 122, and the first composite panel 121, is free of excess material, resulting in an aesthetically pleasing decorative wall (TV wall). Fixing holes 123 for mounting the composite panel assembly 12 on the wall are provided only at the upper and lower ends of the two first composite panels 121. This reduces the number of expansion bolts used during construction, facilitating ease of operation.

[0031] like Figure 4 、 Figure 8As shown, the present invention also provides an assembled wall panel installation structure: including the above-mentioned assembled wall panel installation strip and a protrusion 10 installed on the inner surface of the upper pipe plug 8 and the lower pipe plug 9, the protrusion 10 is long and perpendicular to the inner surface of the upper pipe plug 8 and the lower pipe plug 9, and an arc-shaped extrusion surface 101 is provided at the end of the protrusion 10. When the upper pipe plug 8 and the lower pipe plug 9 enter the locking cavity 13 of the first combination plate 121 and the second combination plate 122, the protrusion 10 is driven to extend into the locking cavity 13 synchronously. The assembled wall panel installation structure also includes a fixing rod 16 and a locking cam 17. The fixing rod 16 is in two rows. One row of fixing rods 16 is fixed to the upper end of the inner surface of the decorative panel 11, and the other row of fixing rods 16 is fixed to the lower end of the inner surface of the decorative panel 11. A rotating hole is opened in the middle of the locking cam 17. The locking cam 17 is in two rows. One row of locking cams 17 is respectively connected to the fixing rods 16 in the upper row through the rotating holes, and the other row of locking cams 17 is respectively connected to the fixing rods 16 in the lower row through the rotating holes. When the decorative panel 11 is fixed to the front side of the combined panel assembly 12, the locking cam 17 in the upper row is in the Below the upper row of protrusions 10, the locking cam 17 of the lower row is located above the protrusions 10 of the lower row. A torsion spring 18 is connected between the locking cam 17 and the fixing rod 16. The torsion spring 18 limits the two bottom positions of the locking cam 17 between the two inner wall surfaces of the locking cavity 13 through elastic action, and reserves a gap between the two inner side surfaces. When the upper pipe plug 8 and the lower pipe plug 9 enter the locking cavity 13, the protrusion 10 is driven to squeeze the locking cam 17 using the arc-shaped extrusion surface 101, so that the two high points of the locking cam 17 rotate to be squeezed on the two inner wall surfaces of the locking cavity 13 respectively. When the upper edge strip 1 is installed on the top of the combined plate assembly 12 by plugging and locking the top of the combined plate assembly 12, in addition to the upper pipe plug 8 being inserted into the locking cavity 13 of the first combined plate 121 and the second combined plate 122, forming a tensioning force on the locking cavity 13, and transmitting the tensioning force between the first combined plate 121 and the second combined plate 122, and between the two adjacent second combined plates 122 to form a strength support for the combined plate assembly 12 in the length direction, the convex block 10 at the bottom end of the upper pipe plug 8 also uses the extrusion surface 101 to squeeze the extrusion locking cam 17 in the lateral direction, so as to force the two high points of the locking cam 17 to rotate to the horizontal position and squeeze the locking cam 17 respectively. On the two inner side walls of the tight cavity 13, since the locking cam 17 is closer to the inner side of the locking cavity 13, the locking cam 17 uses its two high points to rotate to a horizontal state and squeeze on the two inner side walls of the locking cavity 13, which is equivalent to assisting the upper pipe plug 8 to tighten the locking cavity 13 on the inner wall of the locking cavity 13. A structure for tightening the locking cavity 13 outward is formed inside the locking cavity 13, further improving the tension between the first combination plate 121 and the second combination plate 122, and further improving the tension after seamless docking between the two adjacent second combination plates 122, and under the fixing action of the upper side strip 1, the lower side strip 2, the left side strip 3 and the right side strip 4 on the periphery, the strength is improved to prevent deformation.
