Description

Technical Field

[0001] This utility model relates to the field of prefabricated construction workpiece technology, and in particular to a novel steel component for prefabricated construction. Background Technology

[0002] Prefabricated construction involves the standardized and large-scale production of structural components such as walls, floor slabs, beams, and columns in factories, followed by transportation to the construction site and rapid assembly into a complete building system using reliable connection methods. Among the many stages of prefabricated construction, the connection of aluminum profiles is a crucial component. Due to their lightweight, corrosion resistance, high strength, and ease of processing, aluminum profiles are widely used in the exterior wall cladding systems, door and window frames, and interior partitions of prefabricated buildings.

[0003] Currently, angle brackets are a common method for connecting aluminum profiles. Angle brackets are typically made of metal, have specific shapes and sizes, and are fixed to the connection points of the aluminum profiles using bolts, rivets, or welding, thus achieving splicing and fixation between the profiles. However, due to the limited connection strength between the angle brackets and the aluminum profiles, the connection points are prone to loosening, deformation, or even failure under significant external forces such as wind loads, earthquakes, or long-term service loads. This not only affects the building's appearance but also poses a potential threat to the structural safety of the building. Utility Model Content

[0004] In view of this, this utility model proposes a new type of steel component for prefabricated construction, with the aim of improving the installation and connection strength of aluminum profiles.

[0005] The solution provided by this utility model includes:

[0006] A new type of steel component for prefabricated construction, comprising:

[0007] The sleeve body has a square cross-section, and at least one side of it is recessed inward to form a retaining strip portion, and the retaining strip portion is provided with a first connecting hole that penetrates radially.

[0008] A connecting plate is disposed at one end of the sleeve body and corresponds one-to-one with the retaining strip. The length direction of the connecting plate extends radially along the sleeve body. The connecting plate is provided with a second connecting hole that penetrates through its thickness direction.

[0009] Wherein, one end of the retaining strip extends beyond the end of the sleeve body, and the connecting plate is disposed at one end of the retaining strip so that there is a certain distance between the connecting plate and the end of the sleeve body, and the sleeve body and the connecting plate are an integral structure.

[0010] As a further optional solution, a diagonal bracing plate is provided between the two sides of the connecting plate and the card strip.

[0011] As a further alternative, the locking strip is disposed on two opposite sides of the sleeve body.

[0012] As a further alternative, the retaining strip is disposed on the four sides of the sleeve body.

[0013] As a further alternative, at least two first connecting holes are provided, and the first connecting holes are arranged along the length direction of the card strip portion.

[0014] As a further alternative, at least two second connecting holes are provided, and the second connecting holes are arranged along the length direction of the connecting plate.

[0015] As a further alternative, the cross-section of the card strip is C-shaped.

[0016] Compared with the prior art, the novel steel components for prefabricated construction proposed in this application have at least the following advantages:

[0017] The sleeve body is fitted onto an aluminum profile and its shape is adapted to fit it, allowing it to fit tightly against the surface of the aluminum profile and provide stable wrapping support. The retaining strip is inserted into the groove structure on the outside of the aluminum profile, while the protruding connecting plate is inserted into the groove structure on the outside of another aluminum profile. This gives the new steel component and the aluminum profile extremely strong torsional resistance, thereby significantly improving the connection strength between the two aluminum profiles. It effectively prevents the aluminum profiles from shifting in all directions and ensures that the connection remains highly stable when subjected to wind loads, seismic action, and long-term service loads, greatly reducing the risk of connection loosening, deformation, or even failure.

[0033] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0034] refer to Figures 1-3 This utility model discloses a novel steel component for prefabricated construction, used to install aluminum profile 100. It includes a sleeve body 1 and a connecting plate 12. The sleeve body 1 has a square cross-section, with at least one side recessed to form a retaining strip 11. The retaining strip 11 has a first connecting hole 111 that penetrates radially. The connecting plate 12 is disposed at one end of the sleeve body 1 and corresponds one-to-one with the retaining strip 11. The length direction of the connecting plate 12 extends radially along the sleeve body 1. The connecting plate 12 has a second connecting hole 121 that penetrates its thickness direction. One end of the retaining strip 11 extends beyond the end of the sleeve body 1, and the connecting plate 12 is disposed at one end of the retaining strip 11, so that there is a certain distance between the connecting plate 12 and the end of the sleeve body 1. The sleeve body 1 and the connecting plate 12 are an integral structure.

[0035] In some applications, such as connecting two aluminum profiles 100, Figures 3-7 As shown, the sleeve body 1 can be fitted onto an aluminum profile 100. The shape of the sleeve body 1 is adapted to the aluminum profile 100. The side of the aluminum profile 100 is provided with a groove 110, and the retaining strip 11 on the side of the sleeve body 1 can be inserted into the groove 110. During installation, the sleeve body 1 is fitted onto one end of the aluminum profile 100, so that the end of the sleeve body 1 is flush with the end of the aluminum profile 100. Then, a hole is drilled on the aluminum profile 100 at the position corresponding to the first connecting hole 111 of the retaining strip 11, and bolts are used for connection. The component fixes the sleeve body 1 to the aluminum profile 100. After the new steel component is fixed on the aluminum profile 100, the connecting plate 12 protrudes a certain distance from the end of the aluminum profile 100. The connecting plate 12 can be inserted into the groove 110 on the other aluminum profile 100. Then, holes are drilled on the aluminum profile 100 at the position corresponding to the second connecting hole 121. The connecting plate 12 is fixed to the aluminum profile 100 using the bolt assembly. In this way, the installation between the two aluminum profiles 100 can be achieved.

[0036] In the above use cases, such as Figures 4-7 As shown, the retaining strip 11 is disposed on two opposite sides of the sleeve body 1, and the two aluminum profiles 100 are connected in a T-shape. In other embodiments, the sleeve body 1 may have only one retaining strip 11 and one connecting plate 12. This type of novel steel component can achieve an L-shaped connection between the two aluminum profiles 100. Similarly, the retaining strip 11 on the sleeve body 1 can also be three or four. For example, when it is set to four, that is, the retaining strip 11 is disposed on the four sides of the sleeve body 1, so that the end of one aluminum profile 100 can simultaneously form an L-shaped connection with the four aluminum profiles 100.

[0037] In some application scenarios, this new type of steel component for prefabricated construction can also be used to install aluminum profiles 100 onto the plate 200, such as... Figure 8 and Figure 9 As shown, the installation method of the sleeve body 1 and the aluminum profile 100 is almost the same as described above. The difference is that the bottom of the connecting plate 12 is flush with the end of the aluminum profile 100. This allows the end of the aluminum profile 100 and the bottom of the connecting plate 12 to abut against the surface of the plate 200. The plate 200 can be drilled according to the position of the second connecting hole 121 on the connecting plate 12. Then, the connecting plate 12 is fixed to the plate 200 by bolt assembly, thereby realizing the connection between the aluminum profile 100 and the plate 200.

[0038] In some embodiments, such as Figures 1-3 As shown, inclined bracing plates 13 are provided between the two sides of the connecting plate 12 and the locking strip 11. In this embodiment, by adding inclined bracing plates 13, the bending strength of the connecting plate 12 can be effectively improved.

[0039] In some embodiments, to further improve the connection strength between the sleeve body 1 and the aluminum profile 100, such as Figure 3 As shown, at least two first connecting holes 111 are provided, and the first connecting holes 111 are arranged along the length direction of the locking strip portion 11. In addition, at least two second connecting holes 121 are provided, and the second connecting holes 121 are arranged along the length direction of the connecting plate 12.

[0040] In some embodiments, such as Figure 7 As shown, the cross-section of the latching strip 11 is C-shaped. In other embodiments, the cross-section of the latching strip 11 may also be dovetail-shaped, trapezoidal, or other shapes adapted to the slot contour of the aluminum profile 100.

[0041] In summary, this application provides a novel steel component for prefabricated construction. The sleeve body 1 is fitted onto an aluminum profile 100 and its shape is adapted to fit it, allowing it to fit tightly against the surface of the aluminum profile 100 and provide stable wrapping support. The locking strip 11 is inserted into the groove 110 structure on the outside of the aluminum profile 100. At the same time, the protruding connecting plate 12 is inserted into the groove 110 structure on the outside of another aluminum profile 100. This enables the novel steel component and the aluminum profile 100 to have extremely strong torsional resistance, thereby significantly improving the connection strength between the two aluminum profiles 100. It effectively prevents the aluminum profiles 100 from shifting in all directions, ensuring that the connection remains highly stable when subjected to wind loads, seismic forces, and long-term service loads, and greatly reducing the risk of connection loosening, deformation, or even failure.

[0042] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
