Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a plate frame assembly and its construction method. Background Technology

[0002] ALC wall panels (autoclaved aerated concrete partition walls) are increasingly used in traditional concrete frame and steel frame buildings. The traditional installation method for ALC wall panels involves using U-shaped clips for fixing at the top and L-shaped angle steel for fixing to the base plate at the bottom. However, this connection method results in poor overall stability and flatness of the wall panels. Summary of the Invention

[0003] In view of this, the present invention provides a panel frame assembly and its construction method to solve the problem of poor overall stability and flatness of the wall panel.

[0004] In a first aspect, the present invention provides a sheet metal frame assembly, comprising:

[0005] The frame includes a first connecting part and a second connecting part that are spaced apart;

[0008] The connecting structure is installed inside the through channel and is fixedly connected to the fixed structure. The plate is fixedly connected to the frame through the connecting structure.

[0009] Beneficial effects: By opening through channels inside the board material and inserting connecting structures into these channels and fixing them to the fixed structures, the board material can be restrained in a direction perpendicular to the axis of the through channels, thereby improving the overall stability of the structure formed by the board material and the frame, as well as the flatness of the structural plane.

[0010] In one optional embodiment, there are multiple plates, which are spliced ​​together along the line connecting the first connecting part and the second connecting part; the axes of the through channels located on the multiple plates coincide.

[0011] Beneficial effect: By aligning the centerlines of the through channels on multiple plates, the smoothness of the connection structure when it passes through multiple through channels can be ensured.

[0012] In one alternative embodiment, two adjacent plates have two sidewalls that are close to each other. One sidewall is provided with a protruding structure, and the other sidewall is recessed to form a groove structure corresponding to the protruding structure. The protruding structure is adapted to be embedded in the groove structure.

[0013] Beneficial effect: By embedding the protruding structure of one board into the groove structure of the other board, the splicing stability of the two adjacent boards can be enhanced.

[0014] In one alternative embodiment, the plate has multiple through channels, which are arranged in parallel and spaced apart.

[0015] Beneficial effects: By creating multiple through channels on each panel, the stability of the connection between multiple panels and between multiple panels and the frame is further enhanced.

[0016] In one optional embodiment, the plate frame assembly further includes a first fixing part and a second fixing part spaced apart, the first fixing part, the second fixing part, the first connecting part and the second connecting part enclosing a receiving space, the plate being located within the receiving space and abutting against the inner wall of the receiving space.

[0017] Beneficial effects: By abutting the inner wall of the accommodating space against the board, abutting limit is formed on the side of the board near the frame, which helps to improve the stability of the board installed inside the accommodating space.

[0018] In one optional embodiment, the first fixing part and the second fixing part are respectively provided with limiting structures on their adjacent sides, and the plate is provided with limiting grooves corresponding to the limiting structures. At least a part of the limiting structure is located in the limiting grooves to limit the movement of the plate in a direction perpendicular to its main plane.

[0019] Beneficial effects: By ensuring that at least a portion of the limiting structure is located within the limiting groove and abuts against the inner wall of the limiting groove, the stability of the plate installed inside the accommodating space is enhanced.

[0020] In one alternative embodiment, the limiting structure includes a T-shaped structure embedded in the first fixing part or the second fixing part, with a portion of the T-shaped structure exposed on the side of the first fixing part or the second fixing part facing the plate.

[0021] In one optional embodiment, the connection structure includes multiple connecting rods, which are sequentially and fixedly connected along the axial direction of the through channel.

[0022] In one alternative embodiment, a friction element is provided on the outer wall of the connecting structure, and the friction element abuts against the inner wall of the through channel.

[0023] Beneficial effects: By setting friction elements between the connecting structure and the inner wall of the through channel, the connection stability between the connecting structure and the plate is improved.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0037] According to an embodiment of the present invention, in one aspect, a sheet metal frame assembly is provided, comprising:

[0038] The frame includes a first connecting portion 103 and a second connecting portion 104 spaced apart.

[0039] Plate 2 is disposed between the first connecting part 103 and the second connecting part 104;

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

[0041] The connecting structure 5 is installed inside the through channel 201 and is fixedly connected to the fixing structure 4. The plate 2 is fixedly connected to the frame through the connecting structure 5.

[0042] The plate frame assembly provided in this embodiment has a through channel 201 inside the plate 2. By having the connecting structure 5 pass through the through channel 201 and be fixedly connected to the fixing structure 4, the plate 2 is abutted and limited in the direction perpendicular to the axis of the through channel 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 connecting part 103 and the second connecting part 104 can be constructed as a keel, structural beam, or fixed plate, etc. The plate 2 is placed between the first connecting part 103 and the second connecting part 104, with the main plane of the plate 2 parallel to the direction of the first connecting part 103 toward the second connecting part 104. A through channel 201 is formed inside the plate 2. After the plate 2 is placed in position, the position of the through channel 201 corresponds to the position of the fixed structure 4, so that the connecting structure 5 located inside the through channel 201 forms a fixed connection with the fixed structure 4. The adjacent sides of the first connecting part 103 and the second connecting part 104 abut against the plate 2, thereby limiting the movement of the plate 2 in the direction parallel to the first connecting part 103 toward the second connecting part 104. The connecting structure 5 also limits the movement of the plate 2 in the direction perpendicular to the first connecting part 103 toward the second connecting part 104, thus fixing the plate 2 between the first connecting part 103 and the second connecting part 104. Taking the construction of panel 2 as an ALC wall panel as an example, in related technologies, the top of the wall panel is connected with a U-shaped buckle, and the bottom is connected with an L-shaped angle steel to fix the wall panel in the frame. However, during the transportation of the wall panel, some damage may occur at the corners. This connection method requires openings at the corners of the wall panel surface during final installation to embed the U-shaped buckle and the L-shaped angle steel, which may 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. Furthermore, the connection stability is poor when the wall panel is too large or too high. The connection method provided in this embodiment, by opening a through channel 201 inside the panel 2 and forming a fixed connection between the connecting structure 5 inside the through channel 201 and the fixing structure 4, avoids secondary damage to the corners of the panel 2 surface, which is beneficial to improving the surface integrity of the panel 2 and enhancing the overall stability and flatness of the structure formed by the panel 2 and the frame.

[0044] In one embodiment, combined Figures 1 to 7 As shown, there are multiple plates 2, which are spliced ​​together along the line connecting the first connecting part 103 and the second connecting part 104; the axes of the through channels 201 located on the multiple plates 2 coincide.

[0045] The plate frame assembly provided in this embodiment ensures the smoothness of the connection structure 5 when it passes through the multiple through channels 201 by aligning the center lines of the through channels 201 on the multiple plates 2.

[0046] Specifically, after multiple panels 2 are installed in place, the main planes of the multiple panels 2 overlap, and the two sides of two adjacent panels 2 are abutted against each other. Along the length of the through channel 201, the axis of the through channel 201 on one panel 2 coincides with the axis of the through channel 201 on the adjacent panel 2.

[0047] In one embodiment, combined Figures 1 to 7 As shown, two adjacent plates 2 have two sidewalls that are close to each other. One sidewall is provided with a protrusion structure 202, and the other sidewall is recessed to form a groove structure 203 corresponding to the protrusion structure 202. The protrusion 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 joined by embedding the protrusion structure 202 of one plate 2 into 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 adapted to 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 adjacent plate 2, the tightness of the splicing between the two adjacent plates 2 is improved. This helps to avoid the problem of gaps between adjacent plates 2 requiring manual control and prone to leakage, which is common in related technologies. An adhesive is also applied to the contact surface between the protruding structure 202 and the groove structure 203 to further improve the connection stability and tightness between the two adjacent plates 2. The protruding structure 202 can be a monolithic strip or spaced blocks, and the shape of the groove structure 203 is adapted to the shape of the protruding structure 202. Compared to the connection methods using U-shaped clips and L-shaped angle steel in related technologies, the connection method provided in this embodiment can also reduce the gaps between two adjacent plates 2, which helps to improve the overall waterproof performance of the plate frame assembly.

[0050] In one embodiment, combined Figures 1 to 7 As shown, multiple through channels 201 are provided on the plate 2, and the multiple through channels 201 are arranged in parallel and at intervals.

[0051] The plate frame assembly provided in this embodiment further enhances the connection stability between the multiple plates 2 and between the multiple plates 2 and the frame by opening multiple through channels 201 on each plate 2.

[0052] Specifically, each plate 2 is provided with multiple through channels 201, and the number of fixing structures 4 and connecting structures 5 is adapted to the number of through channels 201. By providing multiple through channels 201, the connection stability between the plate 2 and the frame can be enhanced.

[0053] In one embodiment, combined Figures 1 to 7As shown, the plate frame assembly also includes a first fixing part 101 and a second fixing part 102 arranged at intervals. The first fixing part 101, the second fixing part 102, the first connecting part 103 and the second connecting part 104 enclose and form an accommodating space 6. The plate 2 is located in the accommodating space 6 and abuts against the inner wall of the accommodating space 6.

[0054] The plate frame assembly provided in this embodiment, by having the inner wall of the accommodating space 6 abut against the plate 2, forms an abutment limit on the side of the plate 2 near the frame, which helps to improve the stability of the plate 2 installed inside the accommodating space 6.

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

[0056] In one embodiment, combined Figures 1 to 7 As shown, the first fixing part 101 and the second fixing part 102 are respectively provided with limiting structures 3 on their sides that are close to each other. The plate 2 is provided with a limiting groove 204 corresponding to the limiting structure 3. At least a part of the limiting structure 3 is located in the limiting groove 204 to limit the movement of the plate 2 in 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 inside the accommodating space 6 by having at least a portion of the limiting structure 3 located within the limiting groove 204 and abutting against the inner wall of the limiting groove 204.

[0058] Specifically, as one feasible implementation, 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. A limiting groove 204 is formed on the plate 2 corresponding to the position of the limiting structure 3. After the plate 2 is installed in place, the limiting structure 3 falls entirely into the limiting groove 204. As an additional implementation, part of the limiting structure 3 is pre-embedded in the first fixing part 101 or the second fixing part 102, with the remaining part exposed outside 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, combined Figures 1 to 7As shown, the limiting structure 3 includes a T-shaped structure pre-embedded in the first fixing part 101 or the second fixing part 102, with a portion of the T-shaped structure exposed on the side of the first fixing part 101 or the second fixing part 102 facing the plate 2.

[0060] Specifically, as a feasible implementation, the limiting structure 3 is constructed as a T-shape, with part of the structure pre-embedded in the first fixing part 101 or the second fixing part 102. The T-shape structure is made of a hard material such as metal. The limiting groove 204 forms an opening through one side of the main plane of the plate 2, so as to allow space for the limiting structure 3 when the plate 2 is embedded into the receiving space 6. After the plate 2 is installed in place, mortar is filled into the opening to seal it. As an additional implementation, combined with Figure 7 As shown, the limiting structure 3 is constructed with a spring 301 and a moving rod 302 cooperating. The first fixing part 101 and the second fixing part 102 are recessed in a partial area facing the side of the plate 2 to form a receiving groove. The moving rod 302 is slidably disposed within 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 its natural state, a portion of the moving rod 302 is exposed outside the receiving groove. When installing the plate 2, the moving rod 302 is first pressed into the receiving groove, and then the plate 2 is gradually embedded into the receiving cavity. When the plate 2 is in place, the moving rod 302 aligns with the limiting groove 204, and under the elastic action of the spring 301, a portion of it extends into the limiting groove 204.

[0061] In one embodiment, combined Figures 1 to 7 As shown, the connecting structure 5 includes multiple connecting rods, which are sequentially fixedly connected along the axial direction of the through channel 201.

[0062] Specifically, one end of the connecting rod is provided with a threaded sleeve 502, the outer peripheral wall of which is provided with external threads. The other end of the connecting rod is provided with a threaded hole 501, the inner peripheral wall of which is provided with internal threads. The threaded sleeve 502 of one connecting rod and the threaded hole 501 of the adjacent connecting rod are threadedly engaged. The fixing structure 4 can be constructed as a bolt rod or a threaded hole to facilitate threaded connection with the threaded sleeve 502 or the threaded hole 501. Additionally, the fixing connection between two adjacent connecting rods can also be in the form of adhesive or snap-fit ​​connection.

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

[0064] The plate frame assembly provided in this embodiment improves the connection stability between the connecting structure 5 and the plate 2 by setting friction elements between the connecting structure and the inner wall of the through channel.

[0065] Specifically, the friction element can be a rubber pad or a silicone pad. By making the friction element abut against the inner wall of the through channel 201, the relative displacement between the plate 2 and the connecting structure 5 in the direction along the axis of the through channel 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, another aspect provides a construction method for a plate frame assembly, applicable to the above-mentioned plate frame assembly. The construction method includes the following steps: fabricating a frame; providing a fixing structure 4 on the side of the first connecting part 103 and / or the second connecting part 104 near the plate 2; providing a limiting structure 3 on the side of the first fixing part 101 and the second fixing part 102 that are close to each other; opening a through channel 201 and a limiting groove 204 on the plate 2; placing the plate 2 in the accommodating space 6, and ensuring that the limiting structure 3 at least partially falls into the limiting groove 204; and passing a connecting structure 5 through the through channel 201 and fixing it to the fixing structure 4.

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

[0068] When there is only one plate 2 in the frame, the through channel 201 forms an opening through the main plane on one side of the plate 2, so that the connecting structure 5 can be inserted into the through channel 201 in a direction perpendicular to the main plane of the plate 2 to make room. After the connecting structure 5 is inserted into the through channel 201 and fixedly connected to the fixing structure 4, mortar is filled into the opening of the through channel 201 to seal it.

[0069] When there are multiple panels 2 within the frame, the panels 2 are manufactured in batches, with protruding structures 202 and grooved structures 203 respectively set on both sides of the panels 2. Before installation, a layout drawing of the panels 2 is created to plan the quantity of panels 2 and to pre-cut them to avoid waste. Following the splicing sequence of the multiple panels 2, the protruding structure 202 of the first panel 2 is cut off, ensuring the cut surface abuts against the first connecting part 103 or the second connecting part 104. The connecting structure 5 is constructed as multiple connecting rods connected end-to-end, with the connecting rods passing through the through channel 201 along its axial direction and fixedly connected to the fixing structure 4. The subsequent plates 2 and connecting rods are installed sequentially. Multiple limiting structures 3 are respectively provided on the first fixing part 101 and the second fixing part 102 corresponding to the positions of the plates 2. A limiting groove 204 penetrates the plate 2 along the direction from the first connecting part 103 to the second connecting part 104, allowing the plate 2 to move within the accommodating space 6 along the splicing direction of the plates 2. This allows the protruding structure 202 of the plate 2 to be embedded into the groove structure 203 of the adjacent plate 2. Adhesive is applied between the protruding structure 202 and the groove structure 203 to improve the connection stability between the two adjacent plates 2. Before installing the last plate 2 and its corresponding connecting rod, the protruding structure 202 of the last plate 2 is cut off, and an opening is formed on one side of the main plane of the plate 2 corresponding to the through groove 201, allowing the last plate 2 to be embedded into the accommodating space 6 in a 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, a through hole can be made on the first connecting part 103 or the second connecting part 104 at the position corresponding to the through channel 201, so that the connecting structure 5 can be inserted into the through channel 201 through the through hole. In this case, it is not necessary to make the through channel 201 penetrate through the main plane on one side of the plate 2 to form an opening, and the connecting structure 5 can be inserted into the through channel 201.

[0071] The construction method provided in this embodiment helps to ensure the surface flatness of the board 2, improve its integrity and connection stability with the frame, and at the same time improve construction efficiency, reduce costs, and reduce environmental pollution.

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