Description

Technical Field

[0030] It should be noted that the terms used here are only for describing the specific implementation mode and are not intended to limit the exemplary implementation mode according to the present application. As used here, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.

[0031] Please refer to Figures 1-8 , the present invention provides a technical solution:

[0032] A partition wall for installing lightweight ecological decorative boards, comprising a partition wall main body 1, a support plate 2 and an ecological decorative board 6. The front side of the partition wall main body 1 is fixedly connected with the support plate 2. Clamping components 3 are inserted through the upper and lower ends of the support plate 2. The front end of the clamping component 3 is clamped with a keel component 4, and the front end of the clamping component 3 is clamped with a support mounting frame component 5. One side of the support mounting frame component 5 away from the partition wall main body 1 is adhesively fixed with an ecological decorative board 6. Two clamping frames 7 are respectively clamped at the upper and lower ends of the ecological decorative board 6. The support mounting frame component 5 includes a U-shaped positioning frame 51. A fitting plate 52 is slidably connected to one side of the U-shaped positioning frame 51 perpendicular to the ecological decorative board 6. The front side of the fitting plate 52 is fixedly connected with an adjusting component 53. A hanging plate 54 is slidably connected inside the groove of the U-shaped positioning frame 51 facing the ecological decorative board 6. A steel bar 55 is fixedly connected to one side of the hanging plate 54 close to the partition wall main body 1. The adjusting component 53 includes a positioning sleeve 531. A limiting insertion post 532 is fixedly connected to the rear side of the positioning sleeve 531. A countersunk head groove 533 is opened inside the tube at the front end of the positioning sleeve 531. A positioning block 534 is slidably connected to the rear end of the limiting insertion post 532. A limiting groove 535 is opened on the outer side of the positioning block 534. An adjusting screw 536 is screwed inside the positioning block 534.

[0033] As a further implementation of this solution, the clamping component 3 includes a shaft rod 31. A grooved strip plate 32 is fixedly connected to the outer side of the shaft of the shaft rod 31. A number of evenly spaced and equally arrayed plate slots 33 are opened on the side of the grooved strip plate 32 facing the ecological decorative board 6. A rotating pressure plate 34 is fixedly connected to the outer side of the shaft of the shaft rod 31. The grooved strip plate 32 and the rotating pressure plate 34 are parallel to each other. A rubber cushion plate 35 is fixedly connected to the side of the rotating pressure plate 34 facing the partition wall main body 1. The side of the rubber cushion plate 35 away from the rotating pressure plate 34 is adhesively fixed to the partition wall main body 1. The grooved strip plate 32 and the rotating pressure plate 34 are respectively fixedly connected to the outer side of the shaft rod 31 and are parallel to each other. This structural design enables the clamping component 3 to form a stable and relatively movable connection framework. The rubber cushion plate 35 has good elasticity and flexibility and is arranged between the clamping component 3 and the partition wall main body 1 to play a role in buffering and shock absorption. When subjected to external impact force or vibration, the rubber cushion plate 35 can absorb and dissipate part of the energy, reducing the impact on the partition wall main body 1;

[0034] As a further implementation of the present invention, the keel assembly 4 includes a keel body 41, grooves 42 are provided at the upper and lower ends of the keel body 41, a through slot 43 is provided on the side of the keel body 41 close to the partition wall body 1, a through hole 44 is provided on the inner side of the keel body 41, a block 45 is slidably connected to the inner side of the through hole 44, an outer hole 46 is provided on the front side of the keel body 41, an inner hole 47 is provided on the rear side of the keel body 41, an expansion bolt 48 is provided on the inner side of the inner hole 47, and the rear side of the keel body 41 The front side of the partition wall body 1 is fitted, the inner side of the groove 42 is fitted with the outer surface of the card frame 7, the inner side of the groove of the through-hole 43 is in close contact with the outer surface of the steel bar 55, the inner side of the through-hole 44 is provided with a card assembly 3, the opening area of ​​the outer hole 46 is twice the opening area of ​​the inner hole 47, the angle between the expansion bolt 48 and the partition wall body 1 is 90°, the projection of the card block 45 in the vertical direction is an I-shape, the side of the card block 45 away from the partition wall body 1 is an arc-shaped setting, and a part of the card block 45 is set In the inter-board groove 33, one side of the keel body 41 is fitted with one side of the partition wall body 1. This close-fitting design can effectively prevent the keel assembly 4 from shaking or displacing after installation, providing a solid foundation for the entire device structure. The inner side of the through-slot 43 is in close contact with the outer side of the steel bar 55, so that the steel bar 55 is closely fitted with the inner side of the through-slot 43 after being subjected to force. On the one hand, it can improve the firmness of the combination of the two, and on the other hand, the steel bar 55 can be used to guide the alignment of multiple through-slots 43, so that multiple keel bodies 41 are in a state of being parallel to each other. The clamping block 45 is clamped in the inter-board groove 33 and inserted into the through hole 44, which can strengthen the connection between the keel assembly 4 and the clamping assembly 3 and provide better anti-slip performance. The opening area of ​​the inner hole 47 is smaller than the opening area of ​​the outer hole 46, which is conducive to the expansion bolt 48 having a larger operating space during installation, and is convenient for construction personnel to install the expansion bolt 48 on the partition wall body 1 more quickly and accurately, thereby improving the installation efficiency and reliability of the expansion bolt 48.

[0035] As a further implementation of this solution, the fitting plate 52 is in the shape of a cuboid structure and forms an angle of 90° with the vertical plane of the U-shaped positioning frame 51 perpendicular to the main body 1 of the partition wall. The side of the steel bar 55 close to the fitting plate 52 is in contact with the side of the rubber cushion plate 35 away from the fitting plate 52. The hook plates 54 are grouped in pairs, and each pair of hook plates 54 is connected by a spring. Part of the adjusting component 53 is arranged inside the U-shaped positioning frame 51. The projection of the U-shaped positioning frame 51 in the vertical direction is U-shaped. This shape design enables it to better disperse and bear forces from various directions, enhancing the stability and anti-deformation ability of the U-shaped positioning frame 51 itself. There are multiple hook plates 54, and two hook plates 54 are arranged in a vertically symmetric distribution as a group, which can enable the U-shaped positioning frame 51 to obtain uniform support at multiple points in the vertical direction, avoiding deformation or damage due to excessive local stress. The design of the fitting plate 52 enables it to form a larger support surface with the U-shaped positioning frame 51 on one side to ensure the support stability on the other side of the U-shaped positioning frame 51. Part of the adjusting component 53 arranged inside the U-shaped positioning frame 51 can play a positioning role between the U-shaped positioning frame 51 and the fitting plate 52;

[0036] As a further implementation of this solution, the positioning sleeve 531, the positioning block 534, and the adjusting screw 536 are on the same axis. The positioning block 534 and the positioning sleeve 531 are magnetically repulsive. The position of the limit insertion post 532 corresponds to the position of the limit slot 535, and the outside of the limit insertion post 532 is in close contact with the inside of the limit slot 535. The end of the adjusting screw 536 away from the positioning block 534 is arranged in the counterbore 533. By turning the adjusting screw 536, the relative position between the positioning block 534 and the positioning sleeve 531 can be changed. The magnetic repulsion between the positioning block 534 and the positioning sleeve 531 and the position correspondence between the limit insertion post 532 and the limit slot 535 can ensure the accuracy and stability of the movement of the positioning block 534. The design of the counterbore 533 enables the head of the adjusting screw 536 to be embedded therein and not protrude from the surface of the positioning sleeve 531, which can avoid interference between the adjusting screw 536 and other components during installation and use.

[0037] Workflow: First, pull the upper and lower steel bars 55 to move the hook hanging plate 54, and make one side of the steel bar 55 fit with one side of the rubber cushion plate 35. Then, according to the size of the ecological decorative board 6 to be installed, snap the clamping block 45 into the corresponding board slot 33, so that the clamping block 45 and the grooved strip board 32 form an integral body. Next, align the through hole 44 opened in the keel main body 41 with the clamping block 45, and move the keel main body 41 to snap the clamping block 45 into the through hole 44. Since one side of the clamping block 45 is arc-shaped, it can better make the clamping block 45 enter the through hole 44. And during the process of the clamping block 45 being snapped into the through hole 44, because the force generated by the keel main body 41 on the through hole 44 is applied to the grooved strip board 32 through the through hole 44, and the grooved strip board 32 is stressed and applied to the rubber cushion plate 35 through the shaft rod 31 and the rotating pressure plate 34. The shaft rod 31 can rotate in the support plate 2 to allow the rotating pressure plate 34 to perform a certain displacement to make the rubber cushion plate 35 deform. Install multiple keel assemblies 4 onto the clamping assembly 3 in sequence according to the above method, which can make the rubber cushion plate 35 generate deformation and extrude the steel bar 55 at multiple positions, so that the outer side of the steel bar 55 is closely attached to the inner side of the insertion slot 43. At this time, the U-shaped positioning frame 51 can be nailed to the partition wall main body 1 to fix the relative position between the U-shaped positioning frame 51 and the partition wall main body 1. Then, use a screwdriver to turn the adjusting screw 536 to change the relative position between the adjusting screw 536 and the positioning block 534. Through the magnetic repulsive force between the positioning sleeve 531 and the positioning block 534, the positioning block 534 drives the attached plate 52 fixedly connected to it to fit with the partition wall main body 1. The setting of the limiting groove 535 and the limiting insertion post 532 enables the positioning block 534 to ensure better stability during movement, so that the attached plate 52 always remains perpendicular to the U-shaped positioning frame 51 during movement;

[0038] After the pre-installation of the keel assembly 4 and the support mounting frame assembly 5 is completed, the clamping frame 7 is snapped into the groove 42 opened at the lower end of the keel body 41. Then, the lower ends of multiple ecological decorative plates 6 are snapped into the clamping frame 7. Next, another clamping frame 7 is snapped onto the groove 42 opened at the upper end of the keel body 41. Similarly, the upper ends of multiple ecological decorative plates 6 are also snapped into the other clamping frame 7, so that one side of the ecological decorative plate 6 is in contact with one side of the U-shaped positioning frame 51. Observe whether the surface layers between multiple ecological decorative plates 6 are aligned and whether there are defects such as uneven side seams or warping. If there is an uneven side seam, the ecological decorative plate 6 can be removed, the clamping block 45 can be snapped into other inter-board grooves 33, and then a new keel body 41 can be replaced. If there is warping, a screwdriver can be used to turn the adjusting screw 536 to adjust the relative positions of the positioning block 534 and the positioning sleeve 531 to change the distance between the fitting plate 52 and a certain part of the U-shaped positioning frame 51. If there are no defects such as uneven side seams or warping, expansion bolts 48 can be used to fix the keel body 41 more firmly on the partition wall body 1. The opening area of the inner hole 47 being smaller than the opening area of the outer hole 46 is beneficial for the expansion bolt 48 to have a larger operating space during installation. Then, the U-shaped positioning frame 51 and the ecological decorative plate 6 are preliminarily fixed by bonding, and then metal parts are used to firmly fix the ecological decorative plate 6 and the keel body 41, thus completing the installation of the ecological decorative plate 6 on the partition wall body 1.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
