[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0045] Example 1:

[0046] like Figures 1-11 As shown, an embodiment of the present invention provides a lightweight and quickly spliced ​​ALC wall panel, including a wall panel 1, a second limiting member 5, an integrated decorative panel 13 and a plurality of cap buckles 16.

[0047] The wall panel 1 is used to be installed indoors for use as a partition wall. The height of the wall panel 1 is 2.2-3.5m, which is basically the same as the indoor floor height. 2.75M is commonly used (suitable for a floor height of about 2.8M). It is a large wall panel structure. The thickness of the wall panel 1 is 10-18cm, which meets the basic use requirements of indoor partition walls. The width of the wall panel 1 can be designed in various sizes according to actual needs, such as 70cm, 65cm, 50cm and other sizes, and the wall panel 1 can be cut along the width direction to meet the applicable needs of splicing.

[0048] A splicing groove 3 is provided at the bottom of the wall panel 1. During installation, the splicing groove 3 corresponds to the first limiting piece 4 fixed to the ground. The splicing groove 3 is stuck on the outside of the first limiting piece 4, thereby limiting the bottom movement of the wall panel 1. A weight-reducing groove 6 is provided at the top of the wall panel 1. The depth of the weight-reducing groove 6 is greater than 15 cm and less than 1 / 3 of the maximum height of the wall panel 1 (referring to the height between the top of the long plate 6a and the bottom of the wall panel 1). The function of the weight-reducing groove 6 is to reduce the weight of the wall panel 1 and save manufacturing materials. The weight-reducing groove 6 cooperates with the second limiting piece 5 to realize the assembly of the wall panel 1. Short plate pieces 6b and long plate pieces 6a are formed on the wall panel 1 and located on the front and rear sides of the weight-reducing groove 6. The short plate piece 6b is 5-10 cm lower than the long plate piece 6a, which is convenient for assembling the wall panel 1 so that the second limiting piece 5 can be quickly inserted into the weight-reducing groove 6.

[0049] The second limiting member 5 is fixedly installed with the top load-bearing beam. In a standard building house, a screw can be reserved on the top load-bearing beam, and then a nut can be used to fix the second limiting member 5. In other cases, chemical expansion screws can be used for connection to ensure that the second limiting member 5 is firmly connected. The second limiting member 5 includes a vertical plate member 502. The weight-reducing groove 6 of the wall panel 1 is stuck on the vertical plate member 502 of the second limiting member 5. The vertical plate member 502 limits the tilting of the wall panel 1 to ensure that the wall panel 1 has sufficient lateral bearing capacity. A through transverse hole 7 is provided on the front and back sides of the wall panel 1. The transverse hole 7 corresponds to the weight-reducing groove 6. A second transverse screw 11 is passed through the transverse hole 7. Both ends of the second transverse screw 11 extend out of the transverse hole 7. The second transverse screw 11 is positioned on the second transverse screw 11. The front and rear sides of the wall panel 1 are both threadedly installed with a clamping nut 12, and the clamping nut 12 is installed and clamped to fix the second transverse screw 11 to the wall panel 1. The height of the transverse hole 7 corresponds to the bottom of the vertical panel 502, so that the bottom of the vertical panel 502 is against the second transverse screw 11. When the second transverse screw 11 is not installed, the second limiting member 5 can slide a certain amount inside the weight-reducing groove 6 to facilitate the splicing groove 3 to be stuck on the outside of the first limiting member 4. After the position of the wall panel 1 is adjusted, the second transverse screw 11 is installed. The second transverse screw 11 limits the second limiting member 5 from sliding inside the weight-reducing groove 6, that is, at this time the wall panel 1 cannot move up and down, and the wall panel 1 cannot tilt sideways, so that the wall panel 1 is stably connected.

[0050] By designing the structure of the second limiting member 5 and the weight-reducing groove 6, when installing the wall panel 1, the wall panel 1 can be controlled to be in an inclined state first, and the vertical plate member 502 of the second limiting member 5 is first inserted into the inside of the weight-reducing groove 6, and then the wall panel 1 is slowly straightened so that the bottom end of the wall panel 1 is close to the first limiting member 4 until the wall panel 1 is in a vertical state, the wall panel 1 is loosened, and the wall panel 1 falls, and the splicing groove 3 at the bottom of the wall panel 1 is stuck on the first limiting member 4, so that the wall panel 1 can be spliced ​​quickly and efficiently, and the second transverse screw 11 is inserted into the transverse hole 7, and the tightening nut 12 is threadedly installed at both ends of the second transverse screw 11, and then the integrated decorative panel 13 is connected to the end of the second transverse screw 11 through the cap buckle 16. The design of this structure can quickly and efficiently install the integrated decorative panel 13 after the wall panel 1 is installed. In the field of interior decoration, it can greatly save construction time, shorten the construction period, and reduce construction costs.

[0051] In one embodiment, in order to reduce the weight of the wall panel 1 and save the manufacturing cost of the wall panel 1 , weight-reducing holes 2 are opened on the left and right sides of the wall panel 1 .

[0052] In order to facilitate the construction workers to control the wall panel 1 when installing the wall panel 1, a first transverse screw 8 is fixedly connected to the front side of the wall panel 1 near the bottom end. Both ends of the first transverse screw 8 extend out of the wall panel 1. The user can use a long rod with a threaded groove at the end to connect to the first transverse screw 8 to manipulate the wall panel 1, and the first transverse screw 8 can also be used together with the above-mentioned second transverse screw 11 to install the integrated decorative panel 13. The specific installation method is: the integrated decorative panel 13 is connected to the end of the first transverse screw 8 through the cap buckle 16.

[0053] In order to further improve the installation stability of the integrated decorative panel 13, two groups of transverse holes 7 and second transverse screws 11 are provided at the same level. The two groups of second transverse screws 11 and the first transverse screws 8 form an inclined inverted triangle structure.

[0054] In one embodiment, the second limiting member 5 includes: a horizontal plate member 501 and a vertical plate member 502. The horizontal plate member 501 and the vertical plate member 502 are fixedly connected in an L-shape. The horizontal plate member 501 and the vertical plate member 502 are an integral structure. A plurality of through holes 501a are provided on the horizontal plate member 501. The horizontal plate member 501 corresponds to the short plate member 6b, and the space at the top of the short plate member 6b just makes room for the horizontal plate member 501.

[0055] In the second limiting member 5, the horizontal plate member 501 serves as a connection. In order to better fix the second limiting member 5 to the top load-bearing beam, the horizontal plate member 501 and the vertical plate member 502 may be distributed in a T-shape.

[0056] In one embodiment, the cap buckle 16 includes a nut component 1601 , a buckle component 1603 and a clip 1604 .

[0057] The nut member 1601 is threadedly connected to the second transverse screw 11 or the first transverse screw 8. During the connection process, attention should be paid to the depth of the threaded connection of the nut member 1601. It is necessary to ensure that all the reverse fasteners 1603 are on the same vertical plane. A short column 1602 is integrally provided at one end of the nut member 1601 away from the second transverse screw 11 or the first transverse screw 8. A sleeve hole is provided on the reverse fastener 1603, and the reverse fastener 1603 is sleeved on the short column 1602. A clip 1604 is installed on the short column 1602 and located on the outside of the reverse fastener 1603. The clip 1604 is connected to the short column 1602 by a traditional transverse insertion or clamping method. Its main function is to limit the reverse fastener 1603 from sliding out of the short column 1602.

[0058] A transverse slot 13a is fixedly connected to the inner side of the integrated decorative panel 13, and the transverse slot 13a corresponds to the undercut 1603. Generally, two transverse slots 13a are arranged horizontally, corresponding to the horizontal positions of the second transverse screw 11 and the first transverse screw 8 respectively.

[0059] In one embodiment, a gasket 10 is provided on the second transverse screw 11 and located on the inner side of the clamping nut 12. The gasket 10 is used to compensate for the height of the first transverse screw 8 after it is connected to the clamping nut 12, so that the connection effect of the cap buckle 16 on the second transverse screw 11 and the first transverse screw 8 is consistent. An annular gasket 9 is provided on the first transverse screw 8. The annular gasket 9 plays an isolation role to prevent the clamping nut 12 from being directly squeezed on the wall panel 1 of the concrete structure.

[0060] In one embodiment, a gap layer a is formed between the wall panel 1 and the integrated decorative panel 13, and the interior of the gap layer a is filled with foam material. According to actual use requirements, the type of foam material filled in the gap layer a can be a material that plays the role of thermal insulation, sound insulation and noise reduction, fire prevention and waterproofing, bonding and sealing, etc.

[0061] In one embodiment, a top cover seam 15 is provided on the top of the integrated decorative panel 13, and a bottom cover seam 14 is provided on the bottom of the integrated decorative panel 13. Taking into account the influence of the actual installation accuracy and other factors, the size of the integrated decorative panel 13 is generally slightly smaller than the height of the floor. After the integrated decorative panel 13 is installed, there are gaps on the top and bottom, so the bottom cover seam 14 and the top cover seam 15 are used to cover the gaps and beautify the appearance.

[0062] Specifically, the top cover 15 includes: a flat top 1501 and a side shield 1502 that are integrally provided. Figure 11As shown, the flat top 1501 and the side shield 1502 are both double-layer hollow aluminum alloy structures. The flat top 1501 and the side shield 1502 are L-shaped. A notch 1503 is provided at the flat top 1501. At the notch 1503, the flat top 1501 is fixed to the top load-bearing beam using wall nails. The side shield 1502 is located outside the top edge of the integrated decorative panel 13 and is used to block the gap between the top edge of the decorative panel 13 and the wall.

[0063] Specifically, such as Figure 10 As shown, the bottom cover 14 includes: a vertical portion 1401, a horizontal portion 1402, and an inner lining 1403. The vertical portion 1401 and the horizontal portion 1402 are integrally arranged, and the vertical portion 1401 and the horizontal portion 1402 are L-shaped. The side of the inner lining 1403 is provided with a mounting hole 1403a. When the bottom cover 14 is installed, the bottom of the horizontal portion 1402 is pressed on the ground. Therefore, the height of the ground is different according to the different paving methods of the bottom surface. Therefore, when actually installing the bottom cover seam 14, first measure and determine the position of the lining member 1403 relative to the vertical portion 1401, and then fix the lining member 1403 to the inner side of the vertical portion 1401 by self-tapping screws. A snap-on socket 1404 with an upward opening is formed between the lining member 1403 and the vertical portion 1401, and the bottom edge of the integrated decorative panel 13 corresponds to the snap-on socket 1404, that is, the bottom edge of the integrated decorative panel 13 is snapped into the inside of the snap-on socket 1404.

[0064] Example 2:

[0065] The embodiment of the present invention provides an installation and construction method of a lightweight and quickly spliced ​​ALC wall panel, using the lightweight and quickly spliced ​​ALC wall panel of the first embodiment, specifically comprising the following steps:

[0066] S1. Fix the second limiting member 5 on the top load-bearing beam and install the first limiting member 4 on the ground directly below the top load-bearing beam. The first limiting member 4 corresponds to the splicing groove 3 at the bottom of the wall panel 1. The second limiting member 5 and the first limiting member 4 are on the same vertical plane, which respectively limit the top and bottom of the wall panel 1 to prevent the wall panel 1 from tilting sideways.

[0067] S2. Control the wall panel 1 to be in a tilted state. First, insert the vertical plate part 502 of the second limiting part 5 into the inside of the weight-reducing groove 6. Then slowly straighten the wall panel 1 so that the bottom end of the wall panel 1 is close to the first limiting part 4 until the wall panel 1 is in a vertical state. Release the wall panel 1, and the wall panel 1 falls. The splicing groove 3 at the bottom of the wall panel 1 is stuck on the first limiting part 4. At this time, the wall panel 1 can still slide up and down. After sliding, it is easy to tilt sideways and is in an unstable state.

[0068] S3. Then insert the second transverse screw 11 into the transverse hole 7, and threadably install the tightening nuts 12 on both ends of the second transverse screw 11 to fix the second transverse screw 11 to the wall panel 1. At this time, the second transverse screw 11 is against the bottom of the second limiting member 5. At this time, the wall panel 1 cannot slide up and down. The wall panel 1 is in a stable state and can withstand lateral forces.

[0069] S4. Thread the cap buckle 16 at the end of the second horizontal screw 11, and buckle the integrated decorative panel 13 onto the cap buckle 16 to complete the quick installation of the integrated decorative panel 13. Compared with the traditional spliced ​​ALC wall panels, which are not convenient for drilling holes on the side and installing integrated decorative panels, this solution can quickly and efficiently install the integrated decorative panel 13.

[0070] S5. Fill the gap layer a between the wall panel 1 and the integrated decorative panel 13 with foam material to provide additional thermal insulation, sound insulation, fireproofing, waterproofing, bonding and sealing.

[0071] The ALC wall panels formed by splicing do not require the use of concrete and can be quickly disassembled and decomposed later, or the indoor layout can be adjusted (disassembled and reinstalled). They have obvious advantages and good development prospects in the field of interior decoration.

[0072] While embodiments of the present invention 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
