[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0036] Combine the following Figures 1 to 7 , describing an embodiment of the present invention.

[0037] According to an embodiment of the present invention, on the one hand, a plate frame assembly is provided, comprising:

[0038] The frame includes a first connecting portion 103 and a second connecting portion 104 that are spaced apart from each other;

[0039] The plate 2 is disposed between the first connecting portion 103 and the second connecting portion 104;

[0040] The fixing structure 4 is arranged on the side of the first connecting portion 103 and / or the second connecting portion 104 facing the plate 2, and a through groove 201 is opened at a position of the plate 2 corresponding to the fixing structure 4;

[0041] The connecting structure 5 is inserted into the through-channel 201 and fixedly connected to the fixing structure 4 . The plate 2 is fixedly connected to the frame via the connecting structure 5 .

[0042] The plate frame assembly provided in this embodiment has a through groove 201 opened inside the plate 2. The connecting structure 5 is passed through the through groove 201 and fixedly connected to the fixed structure 4 so as to form an abutment limit for the plate 2 in a direction perpendicular to the axis of the through groove 201, thereby improving the stability of the overall structure formed by the plate 2 and the frame and the flatness of the structural plane.

[0043] Specifically, the first connection part 103 and the second connection part 104 can be constructed as a keel, a structural beam or a fixed plate. The plate 2 is placed between the first connection part 103 and the second connection part 104, and the main plane of the plate 2 is parallel to the direction from the first connection part 103 to the second connection part 104. A through groove 201 is provided inside the plate 2. After the plate 2 is placed in place, the position of the through groove 201 corresponds to the position of the fixed structure 4, so that the connection structure 5 located inside the through groove 201 forms a fixed connection with the fixed structure 4. The side surfaces of the first connection part 103 and the second connection part 104 that are close to each other are respectively abutted against the plate 2 to limit the movement of the plate 2 in the direction parallel to the first connection part 103 toward the second connection part 104, and the movement of the plate 2 in the direction perpendicular to the first connection part 103 toward the second connection part 104 is limited by the connection structure 5, so that the plate 2 is fixedly installed between the first connection part 103 and the second connection part 104. Taking the plate 2 constructed as an ALC wall panel as an example, in the related art, the wall panel is connected with a U-shaped clip on the top and an L-shaped angle steel on the bottom, so as to fix the wall panel in the frame. However, during the transportation of the wall panel, the corners will be slightly damaged. This connection method requires opening the corners of the wall panel surface during the final installation to embed the U-shaped clip and the L-shaped angle steel, which will damage part of the wall panel and affect the surface flatness and integrity of the wall structure formed by the wall panel and the frame. In addition, when the wall panel is too large or the height is too high, the connection stability is poor. The connection method provided in this embodiment avoids secondary damage to the corners of the surface of the plate 2 by opening a through groove 201 inside the plate 2 and forming a fixed connection between the connection structure 5 penetrated through the through groove 201 and the fixed structure 4, which is beneficial to improving the surface integrity of the plate 2 and enhancing the stability and flatness of the overall structure formed by the plate 2 and the frame.

[0044] In one embodiment, in combination Figures 1 to 7 As shown, there are multiple plates 2, which are spliced ​​along the connecting line of the first connecting portion 103 and the second connecting portion 104; the axes of the through-channels 201 respectively located on the multiple plates 2 coincide with each other.

[0045] The plate frame assembly provided in this embodiment makes the axis lines of the through grooves 201 on the multiple plates 2 coincide with each other, so as to ensure the smoothness of the connection structure 5 when it is penetrated into the multiple through grooves 201 .

[0046] Specifically, after the multiple plates 2 are installed in place, the main planes of the multiple plates 2 overlap, and the two side surfaces of two adjacent plates 2 are arranged in abutment with each other. Along the length direction of the through-channel 201, the axis of the through-channel 201 on one plate 2 overlaps with the axis of the through-channel 201 on another adjacent plate 2.

[0047] In one embodiment, in combination Figures 1 to 7 As shown, two adjacent side walls of two plates 2 are close to each other, one of which is provided with a protruding structure 202 , and the other side wall is recessed corresponding to the protruding structure 202 to form a groove structure 203 , and the protruding structure 202 is suitable for being embedded in the groove structure 203 .

[0048] In the plate frame assembly provided in this embodiment, two adjacent plates 2 are configured such that the protruding structure 202 of one plate 2 is embedded in the groove structure 203 of the other plate 2, so as to enhance the splicing stability of the two adjacent plates 2.

[0049] Specifically, the shape and size of the protruding structure 202 are matched with the shape and size of the groove structure 203. By embedding the protruding structure 202 of one plate 2 into the groove structure 203 of another plate 2 adjacent thereto, the splicing tightness of the two adjacent plates 2 is improved, which is conducive to avoiding the problem that the gap between the adjacent plates 2 in the relevant technology needs to be manually controlled and is prone to leaks. The contact surface between the protruding structure 202 and the groove structure 203 is also coated with an adhesive to further improve the connection stability and tightness of the two adjacent plates 2. The protruding structure 202 can be in the shape of an integral long strip or in the shape of a block arranged at intervals. The shape of the groove structure 203 is matched with the shape of the protruding structure 202. Compared with the connection method using U-shaped buckles and L-shaped angle steels in the relevant technology, the connection method provided in this embodiment can also reduce the gap between the two adjacent plates 2, which is conducive to improving the overall waterproof performance of the plate frame assembly.

[0050] In one embodiment, in combination Figures 1 to 7 As shown, a plurality of through grooves 201 are formed on the plate 2, and the plurality of through grooves 201 are arranged in parallel and at intervals.

[0051] The plate frame assembly provided in this embodiment has a plurality of through grooves 201 formed on each plate 2, so as to further enhance the connection stability between the plurality of plates 2 and between the plurality of plates 2 and the frame.

[0052] Specifically, a plurality of through grooves 201 are provided on each plate 2, and the number of the fixing structures 4 and the connecting structures 5 matches the number of the through grooves 201. The plurality of through grooves 201 are provided to enhance the connection stability between the plate 2 and the frame.

[0053] In one embodiment, in combination Figures 1 to 7As shown, the plate frame assembly also includes a first fixing portion 101 and a second fixing portion 102 that are spaced apart. The first fixing portion 101, the second fixing portion 102, the first connecting portion 103 and the second connecting portion 104 enclose a receiving space 6. The plate 2 is located in the receiving space 6 and abuts against the inner wall of the receiving space 6.

[0054] The plate frame assembly provided in this embodiment makes the inner wall of the accommodating space 6 abut against the plate 2 to form an abutment limit for the side of the plate 2 close to the frame, which is beneficial to improve the stability of the plate 2 installed inside the accommodating space 6.

[0055] Preferably, the extension directions of the first connection portion 103 and the second connection portion 104 are parallel, and the first fixing portion 101 and the second fixing portion 102 are respectively located at the two ends of the extension directions of the first connection portion 103 and the second connection portion 104, and are respectively fixedly connected to the first connection portion 103 and the second connection portion 104. The first fixing portion 101 and the second fixing portion 102 are plate-shaped or rod-shaped, and abut against the plate 2 to limit the movement of the plate 2 in a direction parallel to its main plane, and limit the plate 2 in a direction perpendicular to the main plane of the plate 2 through the connection structure 5, thereby ensuring the stability of the plate 2 installed inside the accommodating space 6.

[0056] In one embodiment, in combination Figures 1 to 7 As shown, limiting structures 3 are respectively provided on the sides of the first fixing portion 101 and the second fixing portion 102 that are close to each other, and a limiting groove 204 is opened in the plate 2 corresponding to the limiting structure 3, and at least a part of the limiting structure 3 is located in the limiting groove 204 to limit the movement of the plate 2 along the direction perpendicular to its main plane.

[0057] The plate frame assembly provided in this embodiment further enhances the stability of the plate 2 installed in the accommodating space 6 by making at least a portion of the limiting structure 3 located in the limiting groove 204 and abutting against the inner wall of the limiting groove 204 .

[0058] Specifically, as a feasible implementation form, the limiting structure 3 is fixedly connected to the surface of the first fixing part 101 or the second fixing part 102 facing the plate 2, and the plate 2 is provided with a limiting groove 204 at the position corresponding to the limiting structure 3. After the plate 2 is installed in place, the limiting structure 3 falls into the limiting groove 204. As an additional implementation form, part of the limiting structure 3 is pre-embedded in the first fixing part 101 or the second fixing part 102, and the remaining part is exposed in the first fixing part 101 or the second fixing part 102, and falls into the limiting groove 204 after the plate 2 is installed in place.

[0059] In one embodiment, in combination Figures 1 to 7As shown, the limiting structure 3 includes a T-shaped structure embedded in the first fixing portion 101 or the second fixing portion 102 , and a partial area of ​​the T-shaped structure is exposed on the side of the first fixing portion 101 or the second fixing portion 102 facing the plate 2 .

[0060] Specifically, as a feasible implementation form, the limiting structure 3 is constructed as a T-shaped structure, and part of the structure is pre-buried in the first fixing part 101 or the second fixing part 102. The T-shaped structure is made of a hard material such as metal. The limiting groove 204 is formed through the main plane of one side of the plate 2 to form an opening, so that when the plate 2 is embedded in the accommodating space 6, the limiting structure 3 is formed to make way. After the plate 2 is installed in place, the opening is filled with mortar to seal it. As an additional implementation form, combined with Figure 7 As shown, the limiting structure 3 is constructed in the form of a spring 301 and a moving rod 302 matching each other. The first fixing portion 101 and the second fixing portion 102 are recessed toward a local area of ​​the side of the plate 2 to form a receiving groove. The moving rod 302 is slidably arranged in the receiving groove. The spring 301 is located on the side of the moving rod 302 away from the plate 2. One end of the spring 301 abuts against the bottom wall of the receiving groove, and the other end abuts against the moving rod 302. When the spring 301 is in a natural state, a part of the moving rod 302 is exposed in the receiving groove. When installing the plate 2, first press the moving rod 302 into the receiving groove, and then gradually embed the plate 2 into the receiving cavity. When the plate 2 is installed in place, the moving rod 302 is aligned with the limiting groove 204, and a part of the area extends into the limiting groove 204 under the elastic action of the spring 301.

[0061] In one embodiment, in combination Figures 1 to 7 As shown, the connection structure 5 includes a plurality of connection rods, and the plurality of connection rods are fixedly connected in sequence along the axial direction passing through the groove 201 .

[0062] Specifically, a threaded sleeve 502 is provided at one end of the connecting rod, and an outer peripheral wall of the threaded sleeve 502 is provided with an external thread, and a threaded hole 501 is provided at the other end of the connecting rod, and an inner peripheral wall of the threaded hole 501 is provided with an internal thread, and the threaded sleeve 502 of one connecting rod is threadedly matched with the threaded hole 501 of another connecting rod adjacent thereto. The fixing structure 4 can be constructed in the form of a bolt rod or a threaded hole, so as to form a threaded connection with the threaded sleeve 502 or the threaded hole 501. In addition, the fixed connection form of two adjacent connecting rods can also be in the form of gluing or snap connection.

[0063] In one embodiment, in combination Figures 1 to 7 As shown, a friction piece is provided on the outer wall of the connection structure 5 , and the friction piece abuts against the inner wall of the through-channel 201 .

[0064] The plate frame assembly provided in this embodiment provides a friction piece between the connecting structure and the inner wall of the through-channel, so as to improve the connection stability between the connecting structure 5 and the plate 2 .

[0065] Specifically, the friction member can be a rubber pad or a silicone pad. By making the friction member abut against the inner wall of the through groove 201, the relative displacement between the plate 2 and the connecting structure 5 along the axial direction of the through groove 201 can be reduced, which is beneficial to improving the connection stability between the connecting structure 5 and the plate 2.

[0066] According to an embodiment of the present invention, on the other hand, a construction method of a plate frame assembly is also provided, which is applied to the above-mentioned plate frame assembly, and the construction method includes the following steps: making a frame; setting a fixing structure 4 on the side of the first connecting part 103 and / or the second connecting part 104 close to the plate 2; setting a limiting structure 3 on the side where the first fixing part 101 and the second fixing part 102 are close to each other; opening a through groove 201 and a limiting groove 204 on the plate 2; setting the plate 2 in the accommodating space 6, and making the limiting structure 3 at least partially fall into the limiting groove 204; passing the connecting structure 5 through the through groove 201, and fixedly connected to the fixing structure 4.

[0067] Specifically, the first fixing portion 101, the second fixing portion 102, the first connecting portion 103 and the second connecting portion 104 are fixedly connected to form a frame. A fixing structure 4 is provided on the side where the first connecting portion 103 and / or the second connecting portion 104 are close to each other, and a limiting structure 3 is provided on the side where the first fixing portion 101 and the second fixing portion 102 are close to each other.

[0068] When the number of plates 2 in the frame is one, the through groove 201 penetrates through the main plane on one side of the plate 2 to form an opening to make way for the connecting structure 5 to be embedded in the through groove 201 in a direction perpendicular to the main plane of the plate 2. After the connecting structure 5 is embedded in the through groove 201 and fixedly connected to the fixing structure 4, the opening of the through groove 201 is filled with mortar to seal it.

[0069] When there are multiple plates 2 in the frame, the plates 2 are produced in batches, and the protruding structures 202 and the groove structures 203 are respectively provided on both sides of the plates 2. Before installation, a layout plan of the plates 2 is produced to plan the number of plates 2 and to cut them in advance to avoid waste. In the splicing order of the multiple plates 2, the protruding structure 202 of the first plate 2 is cut off, and the cut plane is made to abut against the first connecting portion 103 or the second connecting portion 104. The connecting structure 5 is constructed in the form of multiple connecting rods connected end to end, and the connecting rods are inserted into the through-channel 201 along the axial direction of the through-channel 201 and fixedly connected to the fixed structure 4. The subsequent plates 2 and connecting rods are installed in sequence. A plurality of limiting structures 3 are respectively provided at the positions corresponding to the plates 2 on the first fixing part 101 and the second fixing part 102. The limiting groove 204 penetrates the plates 2 along the direction from the first connecting part 103 to the second connecting part 104, so that the plates 2 can move along the splicing direction of the plates 2 in the accommodating space 6, so that the protruding structure 202 of the plates 2 is embedded in the groove structure 203 of another adjacent plate 2. Adhesive is applied between the protruding structure 202 and the groove structure 203 to improve the connection stability of the two adjacent plates 2. Before installing the last plate 2 and the corresponding connecting rod, the protruding structure 202 of the last plate 2 is cut off, and an opening is formed on the main plane of one side of the plate 2 corresponding to the through groove 201, so that the last plate 2 can be embedded in the accommodating space 6 along the direction perpendicular to the main plane of the plate 2. At this time, the opening is suitable for making way for the connecting rod located at the last plate 2.

[0070] As an additional implementation form, a through hole can be opened on the first connecting portion 103 or the second connecting portion 104 at a position corresponding to the through groove 201, so that the connecting structure 5 can be passed through the through hole into the through groove 201. In this case, there is no need to make the through groove 201 pass through the main plane of one side of the plate 2 to form an opening, and the connecting structure 5 can be passed through the through groove 201.

[0071] The construction method provided in this embodiment is conducive to ensuring the surface flatness of the plate 2, improving its integrity and connection stability with the frame, while improving construction efficiency, reducing costs, and reducing pollution to the environment.

[0072] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
