Description

Technical Field

[0001] This utility model relates to trusses, and more particularly to a steel structure truss. Background Technology

[0002] Trusses are generally assembled from multiple connecting bars, forming multiple triangular structures between them to ensure stability and strength. In a truss, these connecting bars primarily bear tensile or compressive forces along their own axis, thus fully utilizing their strength, saving materials, and reducing weight. Multiple trusses can also be arranged and connected by connecting bars to form spatial structures, which can be used as roof frames for laying corrugated steel sheets, tiles, etc. Steel structure trusses use steel bars of various cross-sections as connecting bars, assembled into trusses through welding, fasteners, and other connection methods. Common steel structure trusses typically incorporate two types of connecting bars between two connecting bars, one for vertical support and the other for diagonal support, forming triangular structures.

[0039] Please see Figure 1 A steel truss structure includes a first connecting strip 1, a second connecting strip 2, multiple vertical supports 3, multiple first diagonal supports 4, and multiple second diagonal supports 5.

[0040] Please see Figure 1 and Figure 2 The first connecting strip 1 includes two first angle irons 1-1 and multiple first connecting plates 1-2. The cross-section of the first angle iron 1-1 is L-shaped, and the multiple first connecting plates 1-2 are fixedly connected between the two first angle irons 1-1. More specifically, the two first angle irons 1-1 are arranged opposite each other, with the horizontal part facing outward and above, and the first connecting plates 1-2 are welded and fixed between the vertical parts of the two first angle irons 1-1.

[0041] The second connecting strip 2 includes two second angle irons 2-1 and multiple second connecting plates 2-2. The cross-section of the second angle irons 2-1 is L-shaped, and the multiple second connecting plates 2-2 are fixedly connected between the two first angle irons 1-1. More specifically, the two second angle irons 2-1 are arranged opposite each other, with the horizontal part facing outward and downward, and the second connecting plates 2-2 are welded and fixed between the vertical parts of the two second angle irons 2-1.

[0042] Please see Figure 1 and Figure 4 Multiple first connecting plates 1-2 and multiple second connecting plates 2-2 are in one-to-one correspondence in the vertical direction. The vertically corresponding first connecting plates 1-2 and second connecting plates 2-2 form a pair of connecting plates 6, and two adjacent connecting plates 6 form a group of connecting plates 7, that is, a group of connecting plates 7 has two first connecting plates 1-2 and two second connecting plates 2-2.

[0043] Please see Figure 1 and Figure 2 Multiple vertical supports are sequentially and fixedly connected to multiple pairs of connecting plates 6. Specifically, the first connecting plate 1-2 extends downwards beyond the first angle iron 1-1, and the second connecting plate 2-2 extends upwards beyond the second angle iron 2-1. The extended portions of both are used for fixed connections to the upper and lower ends of the vertical supports, or more specifically, for welding. Each vertical support includes a first support section 3-1 and a second support section 3-2. The two ends of the first support section 3-1 are fixedly connected to the first side of the first connecting plate 1-2 and the first side of the second connecting plate 2-2, respectively. The two ends of the second support section 3-2 are fixedly connected to the second side of the first connecting plate 1-2 and the second connecting plate 2-2, respectively.

[0044] Please see Figure 2 and Figure 3 In some embodiments, both the first connecting plate 1-2 and the second connecting plate 2-2 include a thinner insertion portion 12-1 and a thicker mounting portion 12-2. That is, the insertion portion 12-1 is used for fixed connection with the first angle iron 1-1 / second angle iron 2-1; the mounting portion 12-2 extends beyond the first angle iron 1-1 / second angle iron 2-1 for fixed connection with the vertical support. The vertical outer wall 12a of the mounting portion 12-2 and the first angle iron 1-1 / second angle iron 2-1 forms a mounting plane for fixed connection with the vertical support. In other words, when the thickness of the mounting portion 12-2 is set, and the vertical support is fixedly connected to the connecting pair 6, its upper end is welded and fixed to the first connecting plate 1-2 and the first angle iron 1-1, and its lower end is welded and fixed to the second connecting plate 2-2 and the second angle iron 2-1.

[0045] Improve the stability of the connection points at both ends of the vertical support to enhance its supporting effect.

[0046] Please see Figure 4 The widths of the first connecting plate 1-2 and the second connecting plate 2-2 are both greater than those of the vertical support 3. After the vertical support is connected to the first connecting plate 1-2 and the second connecting plate 2-2, the first connecting plate 1-2 and the second connecting plate 2-2 both extend beyond the two vertical outer walls 12a of the vertical support, so as to provide a connection for the subsequent first diagonal support 4 and second diagonal support 5.

[0047] Please see Figure 1Multiple first inclined supports 4 are all inclined in the first direction and are sequentially fixedly connected to multiple sets of connecting groups 7. That is, the upper end of the first inclined support 4 is fixedly connected to one of the two first connecting plates 1-2, and the lower end of the first inclined support 4 is fixedly connected to one of the two second connecting plates 2-2. The selected first connecting plates 1-2 and second connecting plates 2-2 are not aligned, causing the first inclined support 4 to be inclined; all the first inclined supports 4 have the same selected first connecting plates 1-2 and second connecting plates 2-2, so that the inclination direction is the same. The first inclined support 4 is located on the first side of the first connecting plate 1-2 / second connecting plate 2-2.

[0048] The inclination direction of the multiple second inclined supports 5 is a second direction opposite to the first direction, and they are sequentially fixedly connected to multiple sets of connecting groups 7. More specifically, refer to the first inclined support 4 described above. The second inclined supports 5 are located on the second side of the first connecting plate 1-2 / second connecting plate 2-2.

[0049] In any connecting group 7, the two first support segments 3-1 and the first diagonal support 4, together with the first angle iron 1-1 and the second angle iron 2-1 on this side, form two stable triangular structures; the two second support segments 3-2 and the second diagonal support 5, together with the first angle iron 1-1 and the second angle iron 2-1 on this side, also form two stable triangular structures. The first diagonal support 4 and the second diagonal support 5, with opposite inclination directions, intersect in an X shape, strengthening the stability between the first connecting strip 1 and the second connecting strip 2.

[0050] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, a fastener 8 is also provided between the first inclined support 4 and the second inclined support 5 in the same connecting group 7 to connect the two. More specifically, the fastener 8 includes a sleeve, a bolt, and a nut. The sleeve is located in the middle of the first inclined support 4 and the second inclined support 5, with its two ends abutting against the first inclined support 4 and the second inclined support 5 respectively. The bolt passes through the first inclined support 4, the sleeve, and the second inclined support 5. The nut is threaded onto the bolt. In addition, the cross-section of the first inclined support 4 and the second inclined support 5 can be U-shaped, and a nut of a suitable size is selected so that the nut can be restricted from rotation after entering the recess.

[0051] Fastener 8 is added to connect the first inclined support 4 and the second inclined support 5, making the first inclined support 4 and the second inclined support 5, which are intersecting in an X shape, more stable.

[0052] Please see Figure 7In some embodiments, the steel truss further includes a third connecting strip 9. The third connecting strip 9 is located between the first support segment 3-1 and the second support segment 3-2, meaning its two sides are respectively attached to all the first support segments 3-1 and all the second support segments 3-2, and correspondingly, to all the first diagonal supports 4 and all the second diagonal supports 5. The third connecting strip 9 is fixedly connected to multiple vertical supports, multiple first diagonal supports 4, and multiple second diagonal supports 5. More specifically, the third connecting strip 9 can be welded and fixed to all the first support segments 3-1, all the second support segments 3-2, all the first diagonal supports 4, and all the second diagonal supports 5; alternatively, the first support segments 3-1 and the second support segments 3-2 of the vertical supports can be fixedly connected to the third connecting strip 9 using bolts and nuts, and the first diagonal supports 4 and the second diagonal supports 5, which are staggered in an X-shape, can also be fixedly connected to the third connecting strip 9 using bolts and nuts. Furthermore, the cross-sections of the first support segments 3-1 and the second support segments 3-2 can be U-shaped, and nuts of appropriate size can be selected so that the nuts are restricted from rotation after entering the recesses.

[0053] The addition of a third connecting strip 9 makes the vertical supports more stable, as well as the first and second diagonal supports 4 and 5 that are intersecting in an X-shape. It also connects all the vertical supports and all the first and second diagonal supports 4 and 5 that are intersecting in an X-shape, making the overall steel truss structure more stable.

[0054] Please see Figure 8 In some embodiments, the steel truss structure also has at least one of the following features: 1. A plurality of first reinforcing plates 10 are fixedly connected between two first angle irons 1-1; 2. A plurality of second reinforcing plates 11 are fixedly connected between two second angle irons 2-1.

[0055] Adding a first reinforcing plate 10 makes the connection between the two first angle irons 1-1 more secure. More specifically, the first reinforcing plate 10 can be T-shaped, with its vertical section inserted into the vertical parts of the two first angle irons 1-1 and its horizontal section fitting against the horizontal parts of the two first angle irons 1-1. It can be fixed by welding or by using bolts and nuts. Adding a second reinforcing plate 11 makes the connection between the two second angle irons 2-1 more secure. The second reinforcing plate 11 is designed with reference to the first reinforcing plate 10.

[0056] Please see Figure 8 Furthermore, the steel structure truss also has at least one of the following features: 1. Both sides of any first connecting plate 1-2 are first reinforcing plates 10; 2. Both sides of any second connecting plate 2-2 are second reinforcing plates 11.

[0057] The first connecting plate 1-2 is supported by two first reinforcing plates 10, and the second connecting plate 2-2 is supported by two second reinforcing plates 11, making the fixed connection between the first connecting plate 1-2 and the first angle iron 1-1, and the fixed connection between the second connecting plate 2-2 and the second angle iron 2-1 more stable and less prone to deformation and displacement.
