Description

Technical Field

[0001] This utility model relates to the technical field of sandwich panel accessories, specifically to a detachable connection component for sandwich panels. Background Technology

[0002] Metal sandwich panels, as a lightweight and high-strength building envelope material, are widely used in industrial and civil construction. This panel system mainly consists of purlins, panels, and connecting components, and offers advantages such as thermal insulation, fire and water resistance, and convenient construction. Figure 1 As shown, during the installation process, construction workers usually use a mortise and tenon joint method from bottom to top to install each sandwich panel in sequence. This installation method is not only easy to operate, but also ensures the integrity and sealing of the wall. Therefore, it is widely used in various factories, warehouses, office buildings and other buildings.

[0003] However, in practical use, metal-faced sandwich panel systems have also revealed some problems that urgently need to be solved. Firstly, in industrial production environments, large equipment often needs to be moved into the factory, requiring the removal of some wall sandwich panels. Secondly, during the building's use, especially at lower levels, wall panels are easily damaged or deformed by impacts from transport vehicles and machinery. When these damaged panels need to be replaced, because the sandwich panels are fixed by interlocking them from top to bottom, construction workers must remove them piece by piece from the top until they reach the panel that needs replacement. This removal method is not only time-consuming and labor-intensive, wasting materials, but also affects the stability of adjacent intact panels, increasing construction difficulty and cost. Therefore, how to improve the connection method of metal-faced sandwich panels to achieve convenient replacement of damaged panels has become a pressing technical problem for the construction industry. Summary of the Invention

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0024] If the description of this utility model involves directions (e.g., up, down, left, right, front, back, outside, inside, etc.), then the directions involved need to be defined. For example, "To clearly express the position and direction described in this utility model, the operator of the instrument is used as a reference, the end closer to the operator is the proximal end, and the end farther from the operator is the distal end." Or, the paper can be used as a reference. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, then this definition is not required.

[0025] A detachable connection assembly for sandwich panels, such as Figure 2 As shown, since sandwich panels are a commercially available structure with an interlocking structure, the two ends of the sandwich panel are defined as a concave end and a convex end, respectively. Both the concave and convex ends are located on the side away from the wall purlin 3. The concave end has a long side 202 to form a concave surface, and the convex end has a notch 102 to form a convex surface. For ease of description, the two sandwich panels connected together are defined as the first sandwich panel 101 and the second sandwich panel 201, respectively. The connecting assembly is used to fix the convex end of the first sandwich panel 101 to the wall purlin 3, as shown. Figures 2-3 As shown, the connecting assembly includes a fixing member 4, a first fastener 5, and a decorative member 6. The fixing member 4 is used to fix one end of the first sandwich panel 101 to the wall purlin 3 in conjunction with the first fastener 5, thereby facilitating disassembly or partial disassembly. The decorative member 6 is used to cover the fixing member 4 and the first fastener 5, achieving an aesthetic effect. The fixing member 4 includes a fixing part, which includes a fixing plate 41 and two support plates 42 disposed on the fixing plate 41. Both support plates 42 extend from the fixing plate 41 to the same side of the fixing plate 41 to form an opening. One support plate 42 abuts against the long side 202 of the concave end, and the other support plate 42 is disposed at the notch 102 of the convex end. The fixing plate 41 is provided with a mounting hole. The first fastener 5 passes through the mounting hole from the opening direction to fix the fixing member 4, the first sandwich panel 101, and the wall purlin 3 together. The decorative member 6 is used to cover the opening, that is, the decorative member 6 is used to cover the fixing member 4 and the first fastener 5. The other end of the first sandwich panel 101 is connected to the wall purlin 3 via a bracket 7 and a second fastener 8, which can be a self-tapping screw.

[0026] In one embodiment of this utility model, the fixing plate 41 is connected end to end with the two support plates 42, and the two support plates 42 are perpendicular to the fixing plate 41. That is, the fixing plate 41 and the two support plates 42 are combined to form a C-shape, and the entrance of the C-shape is the opening. The fixing plate 41 is set close to the convex surface of the first sandwich panel 101, and the two support plates 42 are set away from the convex surface of the first sandwich panel 101.

[0027] In one embodiment of this utility model, the first fastener 5 is a self-tapping screw.

[0028] In one embodiment of this utility model, a mounting base 43 is provided on the side of the fixing plate 41 away from the opening. An elastic element 44 is provided inside the mounting base 43. The elastic element 44 extends out of the mounting base 43 and abuts against the first sandwich panel 101. The elastic element 44 is used to avoid hard friction between the fixing plate 41 and the first sandwich panel 101, reducing the damage rate of the first sandwich panel 101. At the same time, since the elastic element 44 is elastic and can deform, when installing the first fastener 5, the elastic force of the elastic element 44 can be used to adjust the depth of the first fastener 5 into the first sandwich panel 101, thereby adjusting the relative position of the fixing member 4 and the first sandwich panel 101. This also reduces the accuracy requirement for the depth of the first fastener 5 into the first sandwich panel 101. Specifically, the elastic element 44 includes a holding part 441 and an abutting part 442. The holding part 441 is engaged in the mounting base 43, and the abutting part 442 extends out of the mounting base 43 and abuts against the first sandwich panel 101. Specifically, the elastic element 44 can be a rubber strip.

[0029] In one embodiment of this utility model, the elastic element 44 corresponds one-to-one with the mounting base 43, and there are at least two elastic elements 44.

[0030] In one embodiment of this utility model, a waterproof plate 45 is provided on the support plate 42 near the second sandwich panel 201. The waterproof plate 45 extends towards the second sandwich panel 201 and is used to prevent rainwater backflow. In actual use, the support plate 42 near the second sandwich panel 201 is positioned against the bottom surface of the long side 202 of the second sandwich panel 201, or the support plate 42 near the bottom surface of the long side 202 of the second sandwich panel 201. The angle between the waterproof plate 45 and the support plate 42 is less than or equal to 90°, preferably 90°. When encountering rainy or snowy weather, the support plate 42 near the second sandwich panel 201 acts as the first line of defense against water. When water vapor moves from the support plate 42 near the second sandwich panel 201 into the interior of the first sandwich panel 101, the water vapor is difficult to enter the interior of the first sandwich panel 101 due to the blocking effect of the waterproof plate 45.

[0031] As an embodiment of this utility model, a decorative panel 46 is provided on the support plate 42 away from the second sandwich panel 201. The decorative panel 46 extends to the side away from the second sandwich panel 201. The decorative panel 46 is used to cover the notch 102 of the first sandwich panel 101, unify the style of the wall decoration seam, and make it more visually appealing. At the same time, it has a drip line function to prevent water vapor from entering the interior of the first sandwich panel 101. Preferably, the decorative panel 46 is located away from the waterproof plate 45, and the included angle between the decorative panel 46 and the support plate 42 away from the second sandwich panel 201 is 90°.

[0032] As one embodiment of this utility model, such as Figure 4 As shown, the decorative component 6 includes a cover plate 61 and two connectors 62 disposed on the cover plate 61. The two connectors 62 extend from the cover plate 61 toward the same side of the cover plate 61, and the cover plate 61 is connected to the fixing part through the connectors 62.

[0033] As one embodiment of this utility model, the connector 62 is an elastic hook, and a limiting protrusion 47 is provided on the support plate 42. The hook can be locked at the limiting protrusion 47, thereby limiting the maximum distance between the cover plate 61 and the fixing plate 41, and limiting the position of the cover plate 61 between the two support plates 42.

[0034] In one embodiment of this utility model, the hook includes an elastic arm 621 and a hook head 622. The hook head 622 is disposed opposite to an adjacent limiting protrusion 47. The limiting protrusion 47 includes a first limiting surface 471, a guide surface 472, and a second limiting surface 473 arranged in sequence. The second limiting surface 473 is disposed close to the fixing plate 41, and the guide surface 472 faces the decorative member 6. The guide surface 472 is used to guide the movement of the hook head 622 toward the fixing plate 41. The first limiting surface 471 is used to limit the position of the cover plate 61, and the second limiting surface 473 is used to limit the position of the hook head 622 that has completely slid past the guide surface 472. Specifically, the limiting protrusion 47 engages with the wedge surface of the hook head 622, and the hook head 622 slides towards the fixed plate 41 against the guide surface 472. During this process, the elastic arm 621 deforms, allowing the hook head 622 to continuously slide towards the fixed plate 41 along the guide surface 472. When the hook head 622 separates from the guide surface 472, the elastic arm 621 resets under the action of elastic force, driving the hook head 622 to move towards the adjacent support plate 42. The hook head 622 abuts against the second limiting surface 473. At this time, the limiting protrusion 47 and the hook head 622 are locked together. Meanwhile, since the distance between the two elastic arms 621 is fixed, the position of the cover plate 61 between the two support plates 42 no longer changes.

[0035] In one embodiment of this utility model, the two limiting protrusions 47 are arranged opposite to each other, and the two ends of the cover plate 61 are respectively engaged in the slots formed by the limiting protrusions 47 and the ends of the support plate 42. The cover plate 61 always abuts against the first limiting surface 471 and the end face of the support plate 42, or the side of the cover plate 61 facing the fixing plate 41 abuts against the end face of the support plate 42 away from the fixing plate 41. The cover plate 61 always abuts against the end face of the support plate 42, thereby limiting the minimum distance between the cover plate 61 and the fixing plate 41. Therefore, the cover plate 61 can no longer move towards the fixing plate 41, nor can it move towards any of the support plates 42, and the relative positions between the cover plate 61, the fixing plate 41, and the support plate 42 no longer change.

[0036] The detachable connection component provided by this utility model abandons the traditional mortise and tenon joint method between sandwich panels, realizing the partial detachability of adjacent sandwich panels, improving the maintainability of the system, and making the repair, replacement, or adjustment of the internal structure more convenient and efficient. The installation process is simple and quick, not limited by season, climate, or geographical environment, and can be carried out year-round, greatly shortening the project cycle, accelerating project progress, reducing construction costs, and optimizing overall cost. After installation, the problem of wall seepage is solved, the system performance is stable and reliable, and the service life of the building is effectively extended. Its flexible detachable design allows it to be reused in other building projects, significantly reducing the generation of construction waste during construction, making it an environmentally friendly product that combines high quality and high performance. At the same time, it makes the overall wall surface neater and more beautiful, significantly improving the visual effect of the building's appearance.

[0037] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0038] The detailed descriptions listed above are merely specific descriptions of feasible implementation methods of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementation methods or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
