[0002] When building structures such as factory buildings, decorative curtain walls or suspended ceilings, main purlins and secondary purlins are usually erected on the inner and outer wall surfaces to form a skeleton framework. As a decorative connection part, this skeleton framework connects and fixes other plates and external decorations, such as enclosures, aluminum plates and light wall color steel plates, etc. to the main framework on the inner and outer walls; as a decorative connection part for fixing wall plates, this skeleton framework is widely used in non-load-bearing structures and styling decoration scenarios such as factory buildings, decorative curtain walls and roof suspended ceilings.

[0003] When erecting the skeleton framework, on-site construction workers usually weld the secondary purlins to the main purlins through high-altitude welding operations. The risk coefficient of high-altitude welding operations is relatively high, and professional personnel need to hold certificates to work. The high-temperature welding slag splashing during welding is also extremely likely to cause fire hazards; at the same time, when on-site construction workers perform high-altitude welding operations, they are limited by the requirements of the welding station and can only perform one-sided welding, and cannot weld the outer facade side of the skeleton framework, resulting in limited welding points and it is difficult to ensure the strength of the skeleton framework after welding; when on-site construction workers move to the next welding station, they also need to synchronously carry the required welding equipment, which is time-consuming and laborious and affects the construction efficiency.

[0023] Please refer to Figure 1 , Figure 1 which shows a schematic structural diagram of a weld-free metal skeleton frame provided by an embodiment of the present application. As Figure 1 shown, a weld-free metal skeleton frame includes a fixed bracket 1, on which a plurality of main crossbeams 2 are arranged, and a plurality of secondary vertical bars 3 are arranged between adjacent main crossbeams 2; both ends of the secondary vertical bar 3 are respectively hinged to two adjacent main crossbeams 2; the adjacent main crossbeams 2 and secondary vertical bars 3 cooperate with each other to install and fix an external decorative member 4.

[0024] Specifically, the main crossbeam 2 is connected to the fixed bracket 1 at one end as a connecting member and to the secondary vertical bar 3 at the other end. At the same time, the main crossbeam 2 and the secondary vertical bar 3 installed on it together form a skeleton node, and a plurality of skeleton nodes together form a skeleton frame. External decorative members 4 such as light wall color steel plates are installed and connected to the skeleton frame through self-tapping screws to form a composite wall decoration structure. The horizontally arranged main crossbeam 2 serves as the main load-bearing member, and the secondary vertical bars 3 arranged on the upper and lower sides of the main crossbeam 2 serve as connecting members and are connected to two adjacent main crossbeams 2. Two adjacent secondary vertical bars 3 located between two adjacent main crossbeams 2 are connected to the adjacent main crossbeam 2 at the head and tail to form a quadrilateral structure, which has the same shape as the external decorative member 4, and the external decorative members 4 such as light wall color steel plates are arranged in this quadrilateral structure.

[0025] Furthermore, the types of hinge connections between the secondary vertical bar 3 and the main crossbeam 2 include bolt connection, stud connection, self-drilling self-tapping screw connection, self-tapping screw connection, rivet connection, and blind rivet nut connection, etc.

[0026] As an option of the embodiment of the present application, a plurality of main crossbeams 2 are arranged along the length direction of the fixed bracket 1, and adjacent main crossbeams 2 are arranged in parallel. A plurality of secondary vertical blocks 3 are arranged along the length direction of the main crossbeam 2. Two adjacent secondary vertical blocks 3 located between two adjacent main crossbeams 2 are connected to the adjacent main crossbeam 2 at the head and tail to form a quadrilateral structure. The shape of the quadrilateral structure is the same as that of the external decorative member 4 such as a light wall color steel plate. The external decorative member 4 is arranged in the quadrilateral structure and is fixedly connected to the main crossbeam 2 and the secondary vertical block 3 by self-tapping screws.

[0027] As an option of the embodiment of the present application, the main crossbeam 2 includes a crossbeam main body 2-1 and two first connecting parts 2-2. The crossbeam main body 2-1 and the two first connecting parts 2-2 are integrally formed. The crossbeam main body 2-1 serves as the main load-bearing member connecting the external decorative member such as a light wall color steel plate and the main frame of the inner and outer walls, has a certain bending and torsional strength, and provides support for the external decorative member. Two first connecting parts 2-2 extend outward from both sides of the crossbeam main body 2-1. The first connecting part 2-2 cooperates with the second connecting part 3-2 to install the secondary vertical block 3 on the main crossbeam 2. One first connecting part 2-2 is connected to two second connecting parts 3-2, and the two second connecting parts 3-2 are respectively located on both sides of one first connecting part 2-2.

[0028] As an option of the embodiment of the present application, the secondary vertical block 3 includes a vertical block main body 3-1 and two second connecting parts 3-2. The length of the vertical block main body 3-1 is equal to the distance between two adjacent main crossbeams 2 adjacent to the vertical block main body 3-1. Two second connecting parts 3-2 extend outward from both ends of the vertical block main body 3-1. The two second connecting parts 3-2 are arranged parallel to the vertical block main body 3-1. The second connecting part 3-2 is hingedly connected to the adjacent first connecting part 2-2 to fixedly connect the secondary vertical block 3 to the main crossbeam 2.

[0029] As an option of the embodiment of the present application, an even number of first connection holes 2-3 are formed on the first connecting part 2-2, and the even number of first connection holes 2-3 are symmetrically distributed up and down in the height direction of the first connecting part 2-2. An even number of second connection holes 3-3 are formed on the secondary vertical block 3, and the even number of second connection holes 3-3 are evenly distributed on the two second connecting parts 3-2. When the secondary vertical block 3 is hingedly connected to the main crossbeam 2, the second connection holes 3-3 on the secondary vertical block 3 are aligned with the first connection holes 2-3 on the adjacent main crossbeam 2.

[0030] As an option in the embodiments of the present application, in order to facilitate the hinged connection of the secondary vertical baffle 3 to the main cross beam 2, two limiting shoulder structures 3-4 are formed by extending outward on both sides of the vertical baffle body 3-1 on the secondary vertical baffle 3. The limiting shoulder structures 3-4 on the same side of the vertical baffle body 3-1 cooperate with the first connecting portion 2-2 on the main cross beam 2, so that when the secondary vertical baffle 3 is installed, the limiting shoulder structures 3-4 abut against the first connecting portion 2-2 to limit the displacement of the secondary vertical baffle 3 in the height direction of the main cross beam 2. At the same time, since the limiting shoulder structures 3-4 limit the displacement of the secondary vertical baffle 3 in the height direction of the main cross beam 2, it is convenient to align the second connecting hole 3-3 on the secondary vertical baffle 3 with the first connecting hole 2-3 on the main cross beam 2 at this time, and the secondary vertical baffle 3 is hinged to the main cross beam 2 through the aligned second connecting hole 3-3 and first connecting hole 2-3.

[0031] Preferably, the cross-sectional shape of the main cross beam 2 is C-shaped, Z-shaped, square-shaped, V-shaped, T-shaped, L-shaped, U-shaped and several-shaped. Since the side of the main cross beam 2 adjacent to the fixed bracket is connected to the wall frame at the same time, in order to adapt to different shapes of the wall frame, the decorative components are installed on the wall frame through the main cross beam 2, and the main cross beam 2 has a variety of cross-sectional shapes.

[0032] Specifically, when the cross-sectional shape of the main cross beam 2 is C-shaped, the two first connecting portions 2-2 on the main cross beam 2 are located on the same side of the cross beam body 2-1, and the first connecting portion 2-2 and the cross beam body 2-1 together form a C-shaped structure. When the cross-sectional shape of the main cross beam 2 is Z-shaped, the two first connecting portions 2-2 on the main cross beam 2 are located on different sides of the cross beam body 2-1, and the first connecting portion 2-2 and the cross beam body 2-1 together form a Z-shaped structure. When the cross-sectional shape of the main cross beam 2 is square-shaped, the main cross beam 2 includes two cross beam bodies 2-1, the two first connecting portions 2-2 are located between the two cross beam bodies 2-1, and the first connecting portion 2-2 and the cross beam body 2-1 together form a square-shaped structure; at the same time, the square-shaped structure has stronger bearing and anti-bending and torsion capabilities compared with the C-shaped structure.

[0033] As an option in the embodiments of the present application, the metal skeleton frame is used to install decorative components, which is generally arranged on the outer side of the wall. The working environment is relatively complex and is easily affected by wind, sun, rain, etc., resulting in corrosion of the metal skeleton frame. Therefore, anti-rust treatments are carried out on the surfaces of both the main cross beam 2 and the secondary vertical baffle 3 to improve the service life of the metal skeleton frame and prevent the metal skeleton frame from being corroded prematurely; the anti-rust treatment methods for the main cross beam 2 and the secondary vertical baffle 3 include galvanized anti-rust treatment on the surface and applying anti-rust paint on the surface, and also include using anti-rust materials such as stainless steel or aluminum alloy as raw materials for the production of the main cross beam 2 and the secondary vertical baffle 3.
