Description

Technical Field

[0001] The utility model relates to the technical field of building decoration structures, and particularly relates to a metal skeleton node without welding. Background Art

[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 surface. As a decorative connection part, this skeleton surface connects and fixes other plates and external decorations, such as enclosures, aluminum plates and light wall color steel plates, etc. on the main frames of the inner and outer walls; as a decorative connection part for fixing wall plates, this skeleton surface 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 surface, 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 carry out high-altitude welding operations, they are restricted by the requirements of the welding station and can only carry out single-sided welding, and cannot weld the outer facade side of the skeleton surface, resulting in limited welding points and it is difficult to ensure the strength of the skeleton surface 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. Summary of the Utility Model

In addition, the features described in some examples can be combined into other examples.

[0027] Embodiment 1:

[0028] Please refer to Figure 1 , Figure 1 which shows a front view of a solderless metal skeleton node provided by an embodiment of the present application. As Figure 1 shown, a solderless metal skeleton node includes a horizontally arranged main cross beam 1 for bearing, and secondary vertical baffles 2 are evenly arranged on both the upper and lower sides of the main cross beam 1. The secondary vertical baffle 2 is fixedly connected to the adjacent main cross beam 1 by hinge.

[0029] Specifically, one end of the main cross beam 1 is used to install the secondary vertical baffle 2. The main cross beam 1 and the secondary vertical baffles 2 installed on both the upper and lower sides of this end cooperate to form a skeleton node. Multiple skeleton nodes cooperate together to form a skeleton surface. External decorative parts such as light wall color steel plates are installed and connected to the skeleton surface by self-tapping screws; the other end of the main cross beam 1 is connected to the main frame of the inner and outer walls. External decorative parts such as light wall color steel plates are fixedly installed on the main frame of the inner and outer walls through the main cross beam 1 to form a composite wall decoration structure. The horizontally arranged main cross beam 1 serves as the main load-bearing member, and the secondary vertical baffles 2 arranged on both the upper and lower sides of the main cross beam 1 serve as connecting members to connect two adjacent main cross beams 1.

[0030] Further, the types of hinge connections between the secondary vertical baffle 2 and the main cross beam 1 include bolt connection, stud connection, self-drilling tapping screw connection, self-tapping screw connection, rivet connection, and blind rivet nut connection, etc.

[0031] Preferably, reference can be made here Figure 1 to the front view of a weld-free metal skeleton node provided by the embodiment of the present application shown. As Figure 1 shown, the secondary vertical baffles 2 on both the upper and lower sides of the main cross beam 1 are located on the same axis and are perpendicular to the main cross beam 1. Similarly, the secondary vertical baffles 2 on both the upper and lower sides of the main cross beam 1 can also be inclined to the main cross beam 1 to meet the shape requirements of the external decorative parts arranged between the main cross beam 1 and the secondary vertical baffle 2; the main cross beam 1 and the secondary vertical baffle 2 are staggered to form a skeleton surface. One main cross beam 1 is hingedly connected to two secondary vertical baffles 2. Similarly, one secondary vertical baffle 2 is hingedly connected to two main cross beams 1.

[0032] Preferably, reference can be made here Figure 3 to the front view of a weld-free metal skeleton node provided by the embodiment of the present application shown. As Figure 3 shown, the main cross beam 1 includes a cross beam main body 1-1. The cross beam main body 1-1, as the main load-bearing member connecting external decorative parts such as light wall color steel plates and the main frames of the inner and outer walls, has a certain bending and torsional strength, provides support for the skeleton surface and the external decorative parts. One end of the cross beam main body 1-1 is connected to the secondary vertical baffle 2, and the other end is connected to the main frames of the inner and outer walls; two first connection parts 1-2 extend outward from both sides of the cross beam main body 1-1. The first connection parts 1-2 are used to install and fix the secondary vertical baffle 2 on the main cross beam 1, or to install and fix the cross beam main body 1-1 on the main frames of the inner and outer walls; one first connection part 1-2 is installed and connected to two second connection parts 2-2. The two first connection parts 1-2 are perpendicular to the cross beam main body 1-1, and the cross beam main body 1-1 and the two first connection parts 1-2 are integrally formed.

[0033] Preferably, reference can be made here Figure 4 to the side view of the main cross beam provided by the embodiment of the present application shown. As Figure 4 shown, the secondary vertical baffle 2 includes a vertical baffle main body 2-1. The length of the vertical baffle main body 2-1 is equal to the distance between two adjacent main cross beams 1 of the secondary vertical baffle 2. Two second connection parts 2-2 extend outward from both ends of the vertical baffle main body 2-1. The two second connection parts 2-2 are parallel to the vertical baffle main body 2-1. The second connection part 2-2 is hingedly connected to the adjacent first connection part 1-2 to fixedly connect the secondary vertical baffle 2 to the main cross beam 1.

[0034] Preferably, an even number of first connection holes 1-21 are formed on the first connection portion 1-2, and the even number of first connection holes 1-21 are arranged vertically along the height direction of the first connection portion 1-2; a second connection hole 2-21 is formed on the second connection portion 2-2, and the number of the second connection holes 2-21 is half of the number of the first connection holes 1-21; when the main cross beam 1 and the secondary vertical baffle 2 are hingedly connected, the second connection hole 2-21 is aligned with the first connection hole 1-21 on the adjacent first connection portion 1-2.

[0035] Preferably, to prevent the on-site construction workers from being injured by knocking against the sharp parts of the secondary vertical baffle 2 during handling and installation, rounded corners are provided at two top corners of the second connection portion 2-2.

[0036] Preferably, reference can be made here to Figure 4 the side view of the main cross beam provided in the embodiment of the present application shown. As Figure 4 shown, limiting shoulder structures 2-3 extend outwardly on both sides of the secondary vertical baffle 2, and the limiting shoulder structures 2-3 and the second connection portion 2-2 on the same side of the secondary vertical baffle 2 cooperate with each other for positioning, so that the limiting shoulder structures 2-3 are abutted against the first connection portion 1-2, increasing the contact area between the secondary vertical baffle 2 and the main cross beam 1 and facilitating installation and positioning. At the same time, during installation, the first connection hole 1-21 on the first connection portion 1-2 corresponds to the second connection hole 2-21 on the second connection portion 2-2 through the limiting shoulder structures 2-3, that is, they are located on the same horizontal plane, facilitating the on-site construction workers to hingedly connect the secondary vertical baffle 2 to the main cross beam 1.

[0037] Preferably, reference can be made here to Figure 2 、 Figure 5 and Figure 6 , the cross-sectional shape of the main cross beam 1 is C-shaped, Z-shaped, square-shaped, V-shaped, T-shaped, L-shaped, U-shaped and several-shaped to adapt to the structures of different main frames of the inner and outer walls and facilitate the installation of external decorative parts on different main frames of the inner and outer walls. Specifically, there is no height difference between the two first connection portions 1-2 of the C-shaped main cross beam 1; the two first connection portions 1-2 of the Z-shaped main cross beam 1 are not on the same axis, and a height difference is formed between the two first connection portions 1-2; the two first connection portions 1-2 of the square-shaped main cross beam 1 are on the same axis, and there is no height difference between the two first connection portions 1-2. At the same time, compared with the C-shaped main cross beam 1, the square-shaped main cross beam 1 structurally strengthens the beam body 1-1 between the two first connection portions 1-2, so it has stronger load-bearing and anti-bending and torsion capabilities than the C-shaped main cross beam 1.

[0038] Further, the cross-sectional shape of the secondary vertical baffle 2 can be C-shaped, L-shaped and square-shaped, and the secondary vertical baffle 2 and the supporting main cross beam 1 can be of the same specification or different specifications.

[0039] Preferably, the working environment of the skeleton nodes is relatively harsh. Therefore, anti-rust treatments are carried out on the surfaces of the main crossbeam 1 and the secondary vertical baffle 2 of the skeleton nodes to prevent the skeleton nodes from being corroded prematurely and improve the service life of the skeleton nodes. The anti-rust treatment methods include, but are not limited to, galvanizing the surfaces of the main crossbeam 1 and the secondary vertical baffle 2, applying anti-rust paint on the surfaces of the main crossbeam 1 and the secondary vertical baffle 2, and using anti-rust materials such as stainless steel or aluminum alloy as raw materials to manufacture the main crossbeam 1 and the secondary vertical baffle 2.
