[0035] In order to better understand the technical solutions and beneficial effects of the present application, the present application will be further described in detail in combination with specific embodiments:

[0036] As shown in the drawings, Figures 1 to 3 The tensile force transmission connecting structure 10 of one embodiment includes a connecting fixing member 100, a pre-connected tensile force transmission member 200, an anchoring tension member 300, and a plurality of tensile protrusions 400. The connecting fixing member 100 includes a mounting portion 110 and a fixing portion 120 connected with each other. The mounting portion 110 is provided with a mounting hole 111 for connecting with the steel beam 20. Specifically, part of the steel beam 20 is clamped in the mounting hole 111. The pre-connected tensile force transmission member 200 includes a steel embedded rod 210 and a pre-connected plate 220. The pre-connected plate 220 is connected to one end of the steel embedded rod 210 and is used to connect with the steel structure main body 30. The fixing portion 120 is fixedly connected with the pre-connected plate 220. The steel embedded rod 210 is used to combine with the concrete pouring. The anchoring tension member 300 is connected to the other end of the steel embedded rod 210 and is used to combine with the concrete pouring. The cross-sectional area of the anchoring tension member 300 is greater than that of the steel embedded rod 210. The plurality of tensile protrusions 400 are equidistantly arranged on the steel embedded rod 210 along the length direction of the steel embedded rod 210 and are used to combine with the concrete pouring.

[0037] It can be understood that by connecting the mounting portion 110 of the connecting fixing member 100 and the steel beam 20, the connecting fixing member 100 and the steel beam 20 are fixedly connected at the intersection connection of the steel beam 20 using a pin inside the mounting hole 111, which ensures the firmness of the connection of the connecting fixing member 100 and the steel beam 20. Since the pre-connected plate 220 is connected to one end of the steel embedded rod 210, the anchoring tension member 300 is connected to the other end of the steel embedded rod 210, and the fixing portion 120 of the connecting fixing member 100 is fixedly connected to the pre-connected plate 220, when the pre-connected plate 220 is connected to the steel structure main body 30, the steel embedded rod 210 and the anchoring tension member 300 are combined with the concrete pouring, which ensures that the anchoring tension member 300 increases the contact area with the concrete and improves the tensile capacity of the steel embedded rod 210, which ensures that the steel embedded rod 210 can effectively transmit force and avoid stress concentration at the intersection connection of the steel beam 20. Since the plurality of tension protrusions 400 are equidistantly arranged on the steel embedded rod 210 along the length direction of the steel embedded rod 210, and the tension protrusions 400 are combined with the concrete pouring, the friction force between the steel embedded rod 210 and the concrete is increased, and the tensile capacity of the steel embedded rod 210 is further improved, thereby improving the stability and safety of the steel structure building. In one embodiment, the steel embedded rod 210 is a cylindrical steel rod or a square cylindrical steel rod.

[0038] As shown in Figure 1 and Figure 3 In one embodiment, the width of the fixing portion 120 gradually increases in the direction from the pre-connected plate 220 to the mounting portion 110, so that the fixing portion 120 extends from the pre-connected plate 220 to the mounting portion 110, which ensures that the pre-connected plate 220 and the mounting portion 110 are connected through the fixing portion 120, and improves the firmness of the connection between the two.

[0039] Further, in one embodiment, the fixing portion 120 and the mounting portion 110 are integrally formed, which ensures the structural strength of the fixing portion 120 and the mounting portion 110, and ensures that the steel beam 20 effectively transmits force from the mounting portion 110 to the fixing portion 120 and finally to the steel structure main body 30, avoiding stress concentration.

[0040] As shown in Figure 1 and Figure 3As shown in the drawings, in one embodiment, the pre-connection plate 220 has a rectangular structure, the steel embedded rod 210 is fixedly connected to the middle position of the pre-connection plate 220, and a plurality of fixed connection holes 221 are formed at the periphery of the pre-connection plate 220, which are used for fixed connection with the outer wall of the steel structure body 30. It can be understood that, due to the plurality of fixed connection holes 221 formed at the periphery of the pre-connection plate 220, after the steel embedded rod 210 extends into the steel structure body 30, the pre-connection plate 220 is fixedly connected with the outer wall of the steel structure body 30. In this embodiment, the fastening bolts are used to connect the fixed connection holes 221 and the steel structure body 30, that is, the pre-connection plate 220 is connected with the concrete steel column of the steel structure body 30, which ensures the firmness of the connection between the pre-connection plate 220 and the steel structure body 30.

In this embodiment, since the tension-resistant bottom plate 310 and the two hooked side plates 320 are combined with the concrete pouring, it is ensured that the tension-resistant bottom plate 310 provides a certain anchoring force under the action of external factors (such as earthquake force), which reduces the shaking of the steel structure building and improves the tensile capacity of the steel embedded rod 210.

[0042] In one embodiment, the tension-resistant bottom plate 310 and the two hooked side plates 320 are integrally formed, which ensures the structural strength of the tension-resistant bottom plate 310 and the two hooked side plates 320, and further enhances the tensile capacity of the steel embedded rod 210.

[0043] As shown in the drawings, Figure 1 Further, in one embodiment, the anchoring tension-resistant piece 300 has an I-shaped or U-shaped shape, which ensures that the concrete is fully solidified and combined with the anchoring tension-resistant piece 300, and improves the tensile capacity of the steel embedded rod 210.

[0044] As shown in the drawings, Figure 1As shown, in one embodiment, the cross-sectional area of the tensile bottom plate 310 is larger than that of the steel embedded rod 210, and the cross-sectional area of the pre-connection plate 220 is larger than that of the tensile bottom plate 310. In this embodiment, since the cross-sectional area of the tensile bottom plate 310 is larger than that of the steel embedded rod 210, the contact area of the tensile bottom plate 310 with the concrete is increased, the anchoring force of the tensile bottom plate 310 is improved, and thus the tensile capacity of the steel embedded rod 210 is improved. In addition, since the cross-sectional area of the pre-connection plate 220 is larger than that of the tensile bottom plate 310, the pre-connection plate 220 is fixedly connected to the concrete steel column, and the cross-sectional area of the pre-connection plate 220 is not less than that of the tensile bottom plate 310, so that the pre-connection plate 220 does not fall into the concrete steel column.

[0045] As shown in Figure 1 Further, in one embodiment, the plurality of tensile protrusions 400 are arranged on both sides of the central axis of the steel embedded rod 210. In this embodiment, the tensile protrusions 400 arranged symmetrically on both sides of the central axis of the steel embedded rod 210 increase the friction between the steel embedded rod 210 and the concrete, and improve the tensile capacity of the steel embedded rod 210. In one embodiment, the tensile protrusion 400 is a cylindrical protrusion or a square column protrusion.

[0046] As shown in Figure 1 In addition, as shown in Figure 3 The application also provides a roof steel structure building 1, which comprises the tensile force transmission connection structure 10 according to any one of the above embodiments.

Since the pre-connected plate 220 is connected to one end of the steel embedded rod 210, the anchoring anti-tension piece 300 is connected to the other end of the steel embedded rod 210, and the fixed portion 120 of the connecting fixing piece 100 is fixedly connected with the pre-connected plate 220, when the pre-connected plate 220 is connected with the steel structure main body 30, the steel embedded rod 210 and the anchoring anti-tension piece 300 are both combined with the concrete pouring, so that the anchoring anti-tension piece 300 increases the contact area with the concrete, the anti-tension ability of the steel embedded rod 210 is improved, the steel embedded rod 210 can effectively transmit force, the stress concentration of the cross connection of the steel beam 20 is avoided. Since the plurality of anti-tension protrusions 400 are equidistantly arranged on the steel embedded rod 210 along the length direction of the steel embedded rod 210, and the anti-tension protrusions 400 are combined with the concrete pouring, the friction force between the steel embedded rod 210 and the concrete is increased, the anti-tension ability of the steel embedded rod 210 is further improved, so that the stability and safety of the steel structure building are improved.
