Description

Technical Field

[0001] The present invention belongs to the technical field of building decoration, and particularly relates to an installation structure, a prefabricated metal wall panel applying the installation structure, and an installation method. Background Art

[0002] With the development of technology, the application of various materials in interior decoration has become more and more common, and metal composite panels are an important part of them. Currently, the common method for installing metal composite panels in the construction field is to connect the metal composite panels to the keel through connectors. For example, a Chinese patent with the authorization announcement number CN 212478259 U discloses an open installation structure for metal composite panels. Both ends of the metal composite panel have metal frames, and concave cavities are provided at the upper corners of the opposite sides of the two metal frames. A connecting pressing member is provided between the opposite concave cavities, and the connecting pressing member is connected to the steel frame base layer through bolts. The above structure has the following problems: 1. The installation is relatively cumbersome and cannot be installed quickly; during installation, it is necessary to first pre-fix the connecting pressing member to the steel frame base layer through bolts, reserve an insertion space, then insert the metal composite panel, and finally tighten the bolts to realize the pressing and fixing of adjacent two metal composite panels. The operation steps are cumbersome, and it is not easy to control the seam width between adjacent two metal composite panels. When installing a large area of metal composite panels, the problem of inconsistent seam width is likely to occur; 2. The gap between adjacent two metal composite panels is too large, and subsequent filling or decorative treatment is required. Otherwise, the bolts are exposed and not beautiful; the subsequent filling treatment or decorative treatment is time-consuming and laborious, and will increase additional cost expenditures; 3. When a certain metal composite panel in the middle position needs to be disassembled and repaired, it is necessary to disassemble it from one end, so the later maintenance disassembly and assembly are troublesome and not conducive to later maintenance. Summary of the Invention

[0003] In order to solve the problems existing in the above-mentioned prior art, an installation structure, a prefabricated metal wall panel applying the installation structure, and an installation method are provided.

[0004] The technical solution adopted by the present invention to solve its technical problems is:

[0005] The present technical solution proposes an installation structure, including a first clamping member and a second clamping member that are mutually clamped, wherein:

[0006] The first clamping member includes a first plane, and one end of the first plane is bent downward to form a first bending portion arranged vertically; the bottom end of the first bending portion is connected with a clamping portion bent upward;

[0007] The second card member includes a second plane, and one end of the second plane is bent downward to form a vertically arranged second bent portion; the bottom end of the second bent portion is connected to a lower horizontal portion; the other end of the lower horizontal portion is bent upward to form a vertically arranged third bent portion; the end of the third bent portion is connected to an upper horizontal portion; the end of the upper horizontal portion is connected to an arc-shaped guiding portion that bends downward; a vertical extension portion is arranged below the arc-shaped guiding portion; the extension portion and the arc-shaped guiding portion are connected by a transition portion, and a concave depression is formed at the transition portion.

[0008] A receiving space for receiving the engaging portion is formed between the second bent portion and the extension portion; the height of the upper horizontal portion is lower than the height of the second plane; it is set that the distance from the second bent portion to the outermost edge of the arc-shaped guiding portion is L1, and the distance from the second bent portion to the outer edge of the extension portion is L2, satisfying L1 < L2; when the first card member is engaged with the second card member, the end of the engaging portion is engaged at the concave depression, and the first plane presses above the upper horizontal portion and the first plane is flush with the second plane.

[0009] The engaging portion is arc-shaped.

[0010] The engaging portion includes an inclined section that is inclined upward; the end of the inclined section is connected to a positioning section, and the included angle between the positioning section and the inclined section is an obtuse angle.

[0011] An inclined portion that inclines downward is further connected between the upper horizontal portion and the arc-shaped guiding portion.

[0012] The present invention also proposes a prefabricated metal wall panel, which includes a metal plate layer and the above installation structure; adjacent metal plate layers are tightly joined by engaging with the installation structure.

[0013] One end of the metal plate layer is connected to a first card member, and the other end of the metal plate layer is connected to a second card member; the metal plate layer, the first card member, and the second card member are integrally formed.

[0014] The prefabricated metal wall panel is a metal composite panel; the metal composite panel includes a metal plate layer and a composite panel layer connected to the metal plate layer, and the bottom end of the composite panel layer is flush with the lower horizontal portion.

[0015] The present invention also proposes an installation method for a prefabricated metal wall panel, including the following steps:

[0016] Step 1: Lay the first prefabricated metal wall panel on the installation base surface;

[0017] Step 2: Insert screws through the lower horizontal portion of the second card member to achieve fixed connection with the installation base surface;

[0018] Step 3: Install the second prefabricated metal wall panel. The first fastener of the second prefabricated metal wall panel is snapped into the second fastener head of the first prefabricated metal wall panel. After the first fastener and the second fastener are engaged, the first bent portion of the first prefabricated metal wall panel is closely abutted against the second bent portion of the second metal wall panel. The end of the clamping portion is propped and clamped at the recessed socket to form a clamping limit. The metal plate layer of the second prefabricated metal wall panel is laminated above the upper horizontal portion of the first prefabricated metal wall panel, and the metal plate layers of adjacent prefabricated metal wall panels are located on the same horizontal plane to form a close-fitting structure.

[0019] Step 4: Repeat the above steps to install multiple prefabricated metal wall panels.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. Adjacent metal wall panels are snap-fitted and closely joined through the installation structure. The installation structure adopts a first fastener and a second fastener that are snap-fitted with each other. After the first fastener and the second fastener are engaged, the end of the clamping portion is clamped at the recessed socket. The first plane is laminated above the upper horizontal portion and the first plane is flush with the second plane. The clamping portion is bent upward and is arc-shaped. In this way, when engaging, it is convenient for the clamping portion to slide down quickly along the arc-shaped guiding portion. Moreover, the upward bending can also reserve space for installing screws, avoiding collision between the clamping portion and the screws during engagement, so as not to affect the installation speed and effect, and truly achieving the purpose of fast and good installation. In addition, it is set that the distance from the second bent portion to the outermost edge of the arc-shaped guiding portion is L1, and the distance from the second bent portion to the outer edge of the extending portion is L2, satisfying L1 < L2, so that the end of the clamping portion is propped at the recessed socket to form a limit, which can effectively prevent unhooking. After engagement, the first bent portion and the second bent portion are closely abutted, which is a close-fitting style, ensuring a small gap and forming a natural joint. On the one hand, it ensures the consistency of the gap, and on the other hand, it ensures close fitting, and subsequent filling treatment is not required.

[0022] 2. The height of the upper horizontal portion is lower than the height of the second plane. After the first fastener and the second fastener are engaged, the first plane is laminated above the upper horizontal portion and the first plane is flush with the second plane. The upper horizontal portion can play two roles. On the one hand, it plays a positioning role to ensure that the first plane is flush with the second plane, that is, to ensure the flatness of the surface of the metal composite board. On the other hand, it plays a supporting role, making the joint position of the engagement have higher strength.

[0023] 3. When the metal wall panel proposed by the present invention is assembled and installed, there is no need to additionally configure connectors, and it can be directly installed on the keel or the wall surface. It has the advantages of fast installation, time-saving and labor-saving, and good close-fitting effect. After close-fitting, the screws are built-in and hidden, and no additional treatment is required, which is firm and beautiful. In addition, due to the use of snap connection, it also has the advantage of convenient disassembly. Description of the Drawings

[0041] A receiving space 13 for receiving the snap portion 3 is formed between the second bending portion 5 and the extension portion 11; the height of the upper horizontal portion 8 is lower than the height of the second plane 4; it is set that the distance from the second bending portion 5 to the outermost edge of the arc-shaped guiding portion 9 is L1, and the distance from the second bending portion 5 to the outer edge of the extension portion 11 is L2, and L1 < L2 is satisfied; when the first engaging member and the second engaging member are engaged, the end of the snap portion 3 is engaged at the recessed cavity 12, and the first plane 1 is pressed above the upper horizontal portion 8 and the first plane 1 is flush with the second plane 4.

The bottom end of the composite panel layer 17 is flush with the lower horizontal part 6; one end of the composite panel layer is connected to the second bending part 5; there is a gap between the other end and the end point of the clamping part 3, and this gap is used for mating clamping, which facilitates the relative sliding of the arc part along the end point of the clamping part 3, so that the arc part enters this gap to achieve the purpose of clamping.

[0046] Embodiment 2

[0047] As Figures 6 - 7 shown, other structures are the same as those in Embodiment 1. The difference is that the clamping part 3 includes an inclined section 31, and the inclined section 31 is arranged obliquely upward; the end of the inclined section 31 is connected with a positioning section 32, and the included angle between the positioning section 32 and the inclined section 31 is an obtuse angle.

[0053] Step 4: Repeat the above steps to achieve the installation of multiple prefabricated metal wall panels.

[0054] It can be seen from the above embodiments that:

[0055] Adjacent metal wall panels are snap-fitted and closely joined through the installation structure. The installation structure adopts a first clamping member and a second clamping member that are mutually clamped. After the first clamping member and the second clamping member are clamped, the end of the clamping portion 3 is clamped at the recessed socket 12, and the first plane 1 is pressed above the upper horizontal portion 8 and the first plane 1 is flush with the second plane 4; the clamping portion 3 is bent upward and is arc-shaped. In this way, when clamping, it is convenient for the clamping portion 3 to slide down quickly along the arc-shaped guiding portion 9; moreover, bending upward can also reserve space for the installation screws 15 to avoid collision between the clamping portion 3 and the screws during clamping, so as not to affect the installation speed and effect, and truly achieve the purpose of fast and good installation; in addition, the distance from the second bending portion 5 to the outermost edge of the arc-shaped guiding portion 9 is set as L1, and the distance from the second bending portion 5 to the outer edge of the extending portion 11 is set as L2, satisfying L1 < L2, so that the end of the clamping portion 3 abuts against the recessed socket 12 to form a limit, which can effectively prevent unhooking; after clamping, the first bending portion 2 and the second bending portion 5 are close to each other, in a closely joined style, which can ensure a smaller gap and form a natural joint. On the one hand, it ensures the consistency of the gap, and on the other hand, it ensures the close joining, and subsequent filling treatment is not required.

[0056] When the metal wall panel proposed by the present invention is assembled and installed, there is no need to additionally configure connecting parts, and it can be directly installed on the keel or the wall surface, having the advantages of fast installation, time-saving and labor-saving, and good close-joining effect; after close-joining, the screws are internally hidden and do not require additional treatment, being firm and beautiful; in addition, due to the adoption of snap-fitting connection, it also has the advantage of being convenient for disassembly.
