Similarly, the second corrugation creates an undulating shape in the thickness direction of the second steel plate, which, when subjected to forces along its length, distributes the force more evenly on the plane perpendicular to its length, reducing stress concentration and improving out-of-plane stability. Thus, the corrugated T-shaped component provided by this invention has good compressive bearing capacity and out-of-plane deformation resistance, improves buckling resistance and fatigue strength, thereby improving mechanical properties.

[0025] When using the corrugated T-shaped components provided by this invention to construct prefabricated steel structure building systems, the first and second corrugated sections can form an interlocking structure with the spliced ​​components, sharing the load at the splicing position, which is beneficial to improving the overall load-bearing performance and structural stability of the prefabricated steel structure building system.

When multiple corrugated T-shaped components are connected end-to-end, the end caps in one corrugated T-shaped component can be attached and fixedly connected to the end caps in another corrugated T-shaped component.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figures 1-5 As shown, the corrugated T-shaped component provided by the present invention includes: a first corrugated angle steel 1 and a second corrugated angle steel 2, both the first corrugated angle steel 1 and the second corrugated angle steel 2 including a first steel plate leg 10 and a second steel plate leg 20; the first steel plate leg 10 has at least one first corrugated portion 11 distributed along its width direction, and the cross section of the first corrugated portion 11 perpendicular to the length direction of the first steel plate leg 10 is corrugated; the second steel plate leg 20 has at least one second corrugated portion 21 distributed along its width direction, and the cross section of the second corrugated portion 21 perpendicular to the length direction of the second steel plate leg 20 is corrugated; in the first corrugated angle steel 1, the first steel plate leg 10 is a first corrugated angle steel 20, the second steel plate leg 20 is a second corrugated angle steel 20, the second steel plate leg 2 ... One side of the first steel plate limb 10 along its length is fixedly connected to one side of the second steel plate limb 20 along its length; in the second corrugated angle steel 2, one side of the first steel plate limb 10 along its length is fixedly connected to one side of the second steel plate limb 20 along its length; and the first steel plate limb 10 in the first corrugated angle steel 1 and the first steel plate limb 10 in the second corrugated angle steel 2 are fitted and fixed together, the second steel plate limb 20 in the first corrugated angle steel 1 and the second steel plate limb 20 in the second corrugated angle steel 2 are opposite to each other, and the cross section of the corrugated T-shaped member is perpendicular to its length direction and has a T-shaped cross section.

[0046] The first corrugated angle steel 1 includes at least one end sealing plate 50 disposed at the end of the first corrugated angle steel 1. In the first corrugated angle steel 1, one side of the end sealing plate 50 is connected to the first steel plate leg 10, and the other side is connected to the second steel plate leg 20; and / or, the second corrugated angle steel 2 includes at least one end sealing plate 50 disposed at the end of the second corrugated angle steel 2. In the second corrugated angle steel 2, one side of the end sealing plate 50 is connected to the first steel plate leg 10, and the other side is connected to the second steel plate leg 20.

[0047] The first corrugated angle steel 1 and the second corrugated angle steel 2 are connected to form a T-shaped structure, which has good bending resistance. Furthermore, in the first corrugated angle steel 1 and the second corrugated angle steel 2, the first steel plate leg 10 forms an undulating shape in its thickness direction through the first corrugated portion 11. When subjected to forces in its length direction, this makes the distribution of the forces on the plane perpendicular to its own length direction more dispersed, reducing stress concentration and improving out-of-plane stability. Similarly, the second corrugated portion 21 makes the second steel plate leg 20 form an undulating shape in its thickness direction. When subjected to forces in its length direction, this makes the distribution of the forces on the plane perpendicular to its own length direction more dispersed, reducing stress concentration and improving out-of-plane stability. Thus, the corrugated T-shaped component provided by this invention has good compressive bearing capacity and out-of-plane deformation resistance, improves buckling bearing capacity and fatigue strength, thereby improving mechanical properties.

[0048] When using the corrugated T-shaped component provided by the present invention to construct a prefabricated steel structure building system, the first corrugated part 11 and the second corrugated part 21 can form an interlocking structure with the spliced ​​components, and share the force at the splicing position, which is beneficial to improving the overall stress performance and structural stability of the prefabricated steel structure building system.

[0049] The end cap 50 strengthens the connection between the first steel plate leg 10 and the second steel plate leg 20. When multiple first corrugated angle steels 1 are connected end to end, the end cap 50 of one first corrugated angle steel 1 can be attached and fixedly connected to the end cap 50 of another first corrugated angle steel 1; when multiple second corrugated angle steels 2 are connected end to end, the end cap 50 of one second corrugated angle steel 2 can be attached and fixedly connected to the end cap 50 of another second corrugated angle steel 2. By transmitting tensile or compressive force through the end cap 50, the force-bearing area at the connection position is increased, which can effectively improve the load-bearing capacity.

[0050] When manufacturing this corrugated T-shaped component, the first corrugated angle steel 1 and the second corrugated angle steel 2 can be fabricated separately and then fixed together. To make the connection more secure, the first steel plate limb 10 of the first corrugated angle steel 1 is provided with multiple bolt holes, and the first steel plate limb 10 of the second corrugated angle steel 2 is provided with corresponding bolt holes, such as... Figure 2 , Figure 4 and Figure 5 As shown, the first corrugated angle steel 1 and the second corrugated angle steel 2 are fixedly connected together by the bolt 3 that passes through the bolt hole.

[0051] When manufacturing the first corrugated angle steel 1 and the second corrugated angle steel 2, the first steel plate limb 10 and the second steel plate limb 20 can be formed separately, and then the two are connected together by welding, which reduces the difficulty of processing and manufacturing.

[0052] The first steel plate leg 10 in the first corrugated angle steel 1 and the first steel plate leg 10 in the second corrugated angle steel 2 both have a first corrugated portion 11. However, the shape and size of the first steel plate leg 10 in the first corrugated angle steel 1 and the first steel plate leg 10 in the second corrugated angle steel 2 may be the same or different.

[0053] The second steel plate limb 20 in the first corrugated angle steel 1 and the second steel plate limb 20 in the second corrugated angle steel 2 both have a second corrugated portion 21. However, the shape and size of the second steel plate limb 20 in the first corrugated angle steel 1 and the second steel plate limb 20 in the second corrugated angle steel 2 can be the same or different.

[0054] Specifically, in each of the first steel plate legs 10, the number of first corrugated portions 11 can be one or more; when the number of first corrugated portions 11 in a first steel plate leg 10 is multiple, the shape and size of each first corrugated portion 11 can be the same or different.

[0055] In each of the second steel plate limbs 20, the number of second corrugated portions 21 can be one or more; when the number of second corrugated portions 21 in a second steel plate limb 20 is multiple, the shape and size of each second corrugated portion 21 can be the same or different.

[0056] In the first corrugated angle steel 1, the number of first corrugated portions 11 and the number of second corrugated portions 21 may be equal or unequal; the shape and size of the first corrugated portions 11 and the second corrugated portions 21 may be the same or different.

[0057] In the second corrugated angle steel 2, the number of first corrugated portions 11 and the number of second corrugated portions 21 may be equal or unequal; the shape and size of the first corrugated portions 11 and the second corrugated portions 21 may be the same or different.

[0058] Since both the first corrugated angle steel 1 and the second corrugated angle steel 2 include a first steel plate leg 10 and a second steel plate leg 20, for ease of understanding, the following describes the implementation of the first steel plate leg 10 and the second steel plate leg 20, taking the first corrugated angle steel 1 as an example.

[0059] like Figure 7As shown, the width dimension L1 of the first steel plate leg 10 and the width dimension L2 of the second steel plate leg 20 may be equal or unequal. In one embodiment of the present invention, L1 = L2, so that when subjected to a force in the length direction, the force is more evenly distributed between the first steel plate leg 10 and the second steel plate leg 20.

[0060] like Figure 7 As shown, the length dimension L3 of the first steel plate leg 10 and the length dimension L4 of the second steel plate leg 20 can be equal or unequal. Preferably, L3 = L4, and the two ends of the first steel plate leg 10 are flush with the two ends of the second steel plate leg 20.

[0061] To ensure a more uniform force distribution at various locations within the first steel plate limb 10, the first steel plate limb 10 includes multiple first corrugated portions 11 of identical shape and size, such as... Figure 8 As shown, the first corrugated portions 11 are connected end to end in sequence. To ensure a more uniform force distribution at various locations within the second steel plate limb 20, the second steel plate limb 20 includes multiple second corrugated portions 21 of identical shape and size, such as... Figure 8 As shown, each of the second corrugated sections 21 is connected end to end in sequence.

[0062] In the first corrugated angle steel 1, the width direction of the first steel plate leg 10 is denoted as the first direction 12, and each first corrugated portion 11 is distributed along the first direction 12; the width direction of the second steel plate leg 20 is denoted as the second direction 22, and each second corrugated portion 21 is distributed along the second direction 22. The included angle between the first direction 12 and the second direction 22 is denoted as β, and 0° < β < 180°. Preferably, β = 90°.

[0063] The inventors discovered that different shapes of the first corrugated portion 11 result in different force distribution characteristics on the first steel plate leg 10; similarly, different shapes of the second corrugated portion 21 result in different force distribution characteristics on the second steel plate leg 20. Therefore, to further improve the stress characteristics of the first corrugated angle steel 1, the shapes of the first corrugated portion 11 and the second corrugated portion 21 were improved as follows:

[0064] In one embodiment of the present invention, such as Figures 9-14As shown, the cross-section of the first corrugated portion 11 perpendicular to the length direction of the first steel plate leg 10 includes a top edge 33, a first straight edge 31, a bottom edge 34, and a second straight edge 32 connected end to end in sequence, and / or, the cross-section of the second corrugated portion 21 perpendicular to the length direction of the second steel plate leg 20 includes a top edge 33, a first straight edge 31, a bottom edge 34, and a second straight edge 32 connected end to end in sequence. The first straight edge 31 and the second straight edge 32 are both located on the same side of the bottom edge 34. On this side, the first straight edge 31, the bottom edge 34, and the second straight edge 32 surround and form a first groove 35 with an opening; the top edge 33 and the bottom edge 34 are located on both sides of the first straight edge 31, respectively.

[0065] When multiple first corrugated sections 11 are connected end to end, in two adjacent first corrugated sections 11, the second straight edge 32 of the first first corrugated section 11 is connected to the top edge 33 of the second first corrugated section 11.

[0066] When multiple second corrugated sections 21 are connected end to end, in two adjacent second corrugated sections 21, the second straight edge 32 of the first second corrugated section 21 is connected to the top edge 33 of the second second corrugated section 21.

[0067] Preferably, the first steel plate limb 10 includes at least three first corrugated portions 11, and the second steel plate limb 20 includes at least three second corrugated portions 21.

[0068] Furthermore, the top edge 33 and the bottom edge 34 are parallel to each other. In the first steel plate leg 10, both the top edge 33 and the bottom edge 34 are parallel to the first direction 12; in the second steel plate leg 20, both the top edge 33 and the bottom edge 34 are parallel to the second direction 22.

[0069] like Figure 8 As shown, in the first corrugated angle steel 1, the first steel plate leg 10 and the second steel plate leg 20 surround and form the second groove 40. Preferably, the opening of the first groove 35 in the first steel plate leg 10 adjacent to the second steel plate leg 20 faces away from the second groove 40, and the opening of the first groove 35 in the second steel plate leg 20 adjacent to the first steel plate leg 10 also faces away from the second groove 40; or, the opening of the first groove 35 in the first steel plate leg 10 adjacent to the second steel plate leg 20 faces the second groove 40, and the opening of the first groove 35 in the second steel plate leg 20 adjacent to the first steel plate leg 10 also faces the second groove 40. Further, the first steel plate leg 10 and the second steel plate leg 20 are symmetrical.

[0070] In some embodiments, such as Figure 9 As shown, the first straight side 31 and the second straight side 32 are both perpendicular to the bottom side 34, making the shape of the first groove 35 rectangular.

[0071] In some embodiments, such as Figure 10As shown, the angle α between the first straight side 31 and the bottom side 34 and the angle γ between the second straight side 32 and the bottom side 34 are both obtuse angles, making the shape of the first groove 35 an inverted trapezoid. The width of the first groove 35 gradually increases along the direction from the bottom side 34 to the top side 33. Further, 90° < α < 170°, and 90° < γ < 170°. Preferably, α = γ.

[0072] In some embodiments, such as Figure 11 As shown, the angle α between the first straight side 31 and the bottom side 34 and the angle γ between the second straight side 32 and the bottom side 34 are both acute angles, making the shape of the first groove 35 trapezoidal. The width of the first groove 35 gradually decreases along the direction from the bottom side 34 to the top side 33. Further, 10° < α < 90°, and 10° < γ < 9°. Preferably, α = γ.

[0073] To further improve the load-bearing performance of the first corrugated angle steel 1, such as Figures 12-14 As shown, the connections between the top edge 33 and the first straight edge 31, the first straight edge 31 and the bottom edge 34, and the bottom edge 34 and the second straight edge 32 all use rounded transitions. The connections between adjacent corrugated sections 30 also use rounded transitions to reduce stress concentration at the connections and improve the overall strength and load-bearing capacity of the first corrugated angle steel 1. The radius of the rounded transition is denoted as R. In some embodiments, in the first steel plate leg 10, the radii of the rounded transitions at each connection are equal; in the second steel plate leg 20, the radii of the rounded transitions at each connection are equal.

[0074] In one embodiment of the present invention, such as Figure 15 As shown, the cross-sectional shape of the first corrugated portion 11 perpendicular to the length direction of the first steel plate leg 10 is a sine wave with one period, and / or, the cross-sectional shape of the second corrugated portion 21 perpendicular to the length direction of the second steel plate leg 20 is a sine wave with one period. In the first steel plate leg 10, multiple first corrugated portions 11 are connected end-to-end along the first direction 12 to form a continuous sine wave; in the second steel plate leg 20, multiple second corrugated portions 21 are connected end-to-end along the second direction 22 to form a continuous sine wave. Preferably, the angle β between the first direction 12 and the second direction 22 is 90°.

[0075] The structure of the first steel plate limb 10 and the second steel plate limb 20 has been described above. In order to make the connection between the first steel plate limb 10 and the second steel plate limb 20 more secure, the inventors have made further improvements to the connection structure of the first steel plate limb 10 and the second steel plate limb 20.

[0076] The first corrugated angle steel 1 includes at least one end cap 50 disposed at one end of the first corrugated angle steel 1. In the first corrugated angle steel 1, one side of the end cap 50 is connected to the first steel plate leg 10, and the other side is connected to the second steel plate leg 20. The end cap 50 and the first steel plate leg 10 and the end cap 50 and the second steel plate leg 20 can both be connected by welding to ensure high connection strength.

[0077] The overall shape of the end cap can be rectangular or trapezoidal, or other polygonal shapes. Preferably, such as... Figure 7 and Figure 16 As shown, the end cap 50 is generally triangular in shape. The two sides of the triangular end cap 50 are connected to the first steel plate leg 10 and the second steel plate leg 20 respectively, so that there is a large connection length between the end cap 50 and the first steel plate leg 10 and between the end cap 50 and the second steel plate leg 20. At the same time, the space occupied by the end cap 50 is reduced, which facilitates the assembly of the first corrugated angle steel 1 with other components.

[0078] In one embodiment of the present invention, the side of the end cap 50 connected to the first steel plate leg 10 is provided with a wave-shaped curve, and the shape of the wave-shaped curve is the same as the cross-sectional shape of the first corrugated portion 11, so that the end cap 50 and the first corrugated portion 11 engage. The side of the end cap 50 connected to the second steel plate leg 20 is also provided with a wave-shaped curve, and the shape of the wave-shaped curve is the same as the cross-sectional shape of the second corrugated portion 21, so that the end cap 50 and the second corrugated portion 21 engage. In this way, the length of the engagement between the end cap 50 and the first steel plate leg 10 and the length of the engagement between the end cap 50 and the second steel plate leg 20 are further increased, making the connection more secure.

[0079] Furthermore, the length of the end cap 50 connected to the side of the first steel plate leg 10 may be equal to or unequal to the width of the first steel plate leg 10. Preferably, the length of the end cap 50 connected to the side of the first steel plate leg 10 is less than or equal to the width of the first steel plate leg 10, which can reduce the overall size of the first corrugated angle steel 1 while ensuring connection strength.

[0080] The length of the end cap 50 connected to the side of the second steel plate leg 20 may be equal to or unequal to the width of the second steel plate leg 20. Preferably, the length of the end cap 50 connected to the side of the second steel plate leg 20 is less than or equal to the width of the second steel plate leg 20, which can reduce the overall size of the first corrugated angle steel 1 while ensuring connection strength.

[0081] In one embodiment of the present invention, the first corrugated angle steel 1 has two end sealing plates 50, and the two end sealing plates 50 are respectively fixed to both ends of the first corrugated angle steel 1. Figure 6 and Figure 7As shown, the first corrugated angle steel 1 includes at least one pre-tension member 60. The two ends of the pre-tension member 60 are respectively connected to the end sealing plates 50 located at both ends. The pre-tension member 60 applies tension to the end sealing plates 50, which can improve the stress performance of the first corrugated angle steel 1 and increase its load-bearing capacity.

[0082] The end-sealing plate 50 can be disposed between the first steel plate leg 10 and the second steel plate leg 20, abutting against the inner side surfaces of the first steel plate leg 10 and the second steel plate leg 20 respectively, or it can be disposed on the end face of the first steel plate leg 10. Preferably, the end-sealing plate 50 is disposed on the end face of the first steel plate leg 10, abutting against the end face of the first steel plate leg 10 and the end face of the second steel plate leg 20, so that the end-sealing plate 50 can apply pressure to the first steel plate leg 10 and the second steel plate leg 20 under the pre-tensioning action of the pre-tensioning member 60.

[0083] Furthermore, the end cap 50 is provided with component holes 51; the first corrugated angle steel 1 includes an anchor 61 located on the outer end face of the end cap 50, and the pre-tensioned component 60 passes through the component hole 51 and is fixedly connected to the anchor 61. After being prestressed, the pre-tensioned component 60 is fixed to the end cap 50 by the anchor 61.

[0084] In some embodiments, there are multiple pretension members 60, the length direction of each pretension member 60 is parallel to the length direction of the first steel plate leg 10, and both ends are respectively connected to the end sealing plates 50 located at both ends.

[0085] In some embodiments, the prestressed member 60 is a prestressed cable 62. Specifically, the prestressed cable 62 can be a prestressed steel strand or a prestressed steel wire.

[0086] In one embodiment of the present invention, the first corrugated angle steel 1 includes at least one rib 70, the two sides of which are respectively connected to the first steel plate leg 10 and the second steel plate leg 20. The rib 70 enhances the strength of the first corrugated angle steel 1 and further improves its load-bearing performance. When there are multiple ribs 70, the multiple ribs 70 are spaced apart along the length direction of the first steel plate leg 10. In some embodiments, the rib 70 is provided with a member hole 51 for the pre-tensioning member 60 to pass through.

[0087] Furthermore, the shape of the rib 70 is the same as that of the end cap 50. The rib 70 is generally triangular in shape; the side of the rib 70 connected to the first steel plate leg 10 is shaped as a wave curve, and the shape of the wave curve is the same as the cross-sectional shape of the first corrugated portion 11, so that the end cap 50 and the first corrugated portion 11 can be engaged; the side of the rib 70 connected to the second steel plate leg 20 is shaped as a wave curve, and the shape of the wave curve is the same as the cross-sectional shape of the second corrugated portion 21, so that the end cap 50 and the second corrugated portion 21 can be engaged, thereby reducing the overall size of the first corrugated angle steel 1 while ensuring the connection strength.

[0088] In some embodiments, the rib 70 is connected to the first steel plate limb 10 and the rib 70 is connected to the second steel plate limb 20 by welding to ensure high connection strength.

[0089] The above describes various embodiments of the structure of the first steel plate leg 10 and the second steel plate leg 20 in the first corrugated angle steel 1, as well as various embodiments of the connection structure between them. The structure of the first steel plate leg 10 and the second steel plate leg 20 in the second corrugated angle steel 2, and the connection structure between them, can be any of the various embodiments of the first corrugated angle steel 1 described above, and the first corrugated angle steel 1 and the second corrugated angle steel 2 can be the same or different.

[0090] The connection method between the first corrugated angle steel 1 and the second corrugated angle steel 2 will be described next.

[0091] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the first groove 35 of the first steel plate leg 10 in the first corrugated angle steel 1 is opposite to the first groove 35 of the first steel plate leg 10 in the second corrugated angle steel 2. The protruding portion of the first steel plate leg 10 in the first corrugated angle steel 1 abuts against the protruding portion of the first steel plate leg 10 in the second corrugated angle steel 2, forming through holes spaced apart along the first direction 12 between the first corrugated angle steel 1 and the second corrugated angle steel 2. After the corrugated T-shaped component provided by the present invention is assembled into the component system, the through holes can play a vibration absorption role, reducing damage to the component system when subjected to external impact.

[0092] Preferably, the first corrugated angle steel 1 and the second corrugated angle steel 2 are symmetrical to improve the overall stability of the component.

[0093] In other embodiments of the invention, such as Figure 3 and Figure 4 As shown, the first corrugated part 11 in the first corrugated angle steel 1 and the first corrugated part 11 in the second corrugated angle steel 2 engage with each other, increasing the area of ​​engagement between the first corrugated angle steel 1 and the second corrugated angle steel 2. Furthermore, the engaging structure can prevent relative slippage between the first corrugated angle steel 1 and the second corrugated angle steel 2, thereby improving the connection strength of the connection and enhancing the overall load-bearing performance of the component.

[0094] The above descriptions are merely a few embodiments of the present invention. Those skilled in the art can make various modifications or variations to the embodiments of the present invention based on the content disclosed in the application documents without departing from the spirit and scope of the present invention.
