[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0028] like Figure 1 and Figure 2 As shown, the utility model provides a steel structure cantilevered eaves assembly, the steel structure cantilevered eaves assembly includes a column 11, a cantilevered eaves 12 and a fixing plate 21, the cantilevered eaves 12 has a plurality of connection ends 121, the fixing plate 21 is wrapped on the column 11 along the circumference of the column 11, the fixing plate 21 has a connection surface 211, and the connection surface 211 is used to connect with the connection end 121. A first ring plate 22 and a second ring plate 23 are also provided on the fixing plate 21, and the first ring plate 22 and the second ring plate 23 are arranged at intervals in the vertical direction, and the first ring plate 22 and the second ring plate 23 both have openings 221 corresponding to the connection surface 211, and the first ring plate 22 and the second ring plate 23 are connected to the side wall of the connection end 121 through the corresponding openings 221.

[0029] In this embodiment, the column 11 is arranged in the vertical direction, and the column 11 can be a concrete column or a steel structure column, and the column 11 can be fixed to a steel structure building or the ground. The fixing plate 21 can be arranged in a ring shape so that the fixing plate 21 can be wrapped around the outer peripheral surface of the column 11, and a connecting surface 211 is also provided on the fixing plate 21, and the connecting surface 211 is used to connect with the connecting end 121 of the overhanging eaves 12 to fix the overhanging eaves 12, thereby avoiding the overhanging eaves 12 from being directly fixed to the column 11, and reducing the influence of the welding of the overhanging eaves 12 on the structural strength of the column 11, which helps to reduce the existence of safety hazards.

[0030] Furthermore, the first ring plate 22 and the second ring plate 23 are correspondingly wrapped around the outer side of the fixed plate 21, and the first ring plate 22 and the second ring plate 23 both have an opening 221 corresponding to the connecting surface 211. The first ring plate 22 and the second ring plate 23 are connected to the side wall of the connecting end 121 through the corresponding openings 221, which helps to improve the connection strength between the connecting end 121 and the fixed plate 21 while ensuring the wrapping strength of the fixed plate 21 on the column 11, that is, the connecting end 121 is not only connected to the fixed plate 21, but also connected to the first ring plate 22 and the second ring plate 23 on the fixed plate 21; and the openings 221 set on the first ring plate 22 and the second ring plate 23 can also be used to limit the fixed position of the connecting end 121, thereby ensuring the installation accuracy of the cantilevered eaves 12.

[0031] Furthermore, intermittent welding is used to achieve connection between the fixed plate 21 and the column 11, that is, the weld is divided into multiple sections for welding, which can reduce the heat and stress generated during the welding process, thereby reducing deformation and avoiding internal stress. In addition, intermittent welding can more easily control deformation and internal stress, thereby improving welding efficiency and quality.

[0032] The welding distance in intermittent welding can be 80 mm to 120 mm, so as to avoid the welding distance being too large, which increases the length of the weld and reduces the connection strength, and to avoid the welding distance being too small, which may cause defects such as bubbles and pores during welding. In this embodiment, the welding distance between the fixing plate 21 and the column 11 is 100 mm.

[0033] In this embodiment, the column 11 is a steel structure column 11, and the overhanging length of the overhanging eaves 12 relative to the column 11 is 5000mm to 11000mm. Figure 1 As shown, the overhanging eaves 12 have at least two connecting ends 121 to ensure the structural strength of the overhanging eaves 12. For example, the overhanging length of the overhanging eaves 12 relative to the column 11 can be set to 5990mm, 6710mm, 6950mm, 7095mm, 10410mm or 11000mm. In some embodiments, the connecting ends 121 of the overhanging eaves 12 can also be fixed to different columns 11 to improve the overall structural strength.

[0034] In some embodiments, Figure 2 and Figure 3 As shown, the first ring plate 22 is connected to the top of the fixed plate 21, and the distance between the first ring plate 22 and the upper edge of the fixed plate 21 is less than or equal to a first threshold, and the second ring plate 23 is connected to the bottom of the fixed plate 21, and the distance between the second ring plate 23 and the lower edge of the fixed plate 21 is less than or equal to a second threshold, so that the loads borne by the first ring plate 22 and the second ring plate 23 are more consistent, and the supporting strength of the connecting end 121 is more consistent.

[0035] In this embodiment, the first threshold value may be 1 / 10 to 2 / 10 of the axial width of the fixing plate 21, and the second threshold value may be 1 / 10 to 2 / 10 of the axial width of the fixing plate 21, so as to ensure the connection strength between the fixing plate 21, the connecting end 121 and the column 11, thereby improving the structural strength of the steel structure cantilevered eaves assembly. Of course, in some embodiments, the first threshold value may also be set to 15 mm to 35 mm, and the second threshold value may also be set to 15 mm to 35 mm.

[0036] Furthermore, the first ring plate 22 and the second ring plate 23 are symmetrically arranged on the fixing plate 21, and the first threshold and the second threshold can be set to be the same, so that the loads borne by the first ring plate 22 and the second ring plate 23 are more consistent, avoiding stress concentration.

[0037] Furthermore, the thickness of the fixing plate 21 is 12 mm to 25 mm, so that the fixing plate 21 has sufficient structural strength to prevent the fixing plate 21 from deforming and affecting the structural strength of the column 11. The thickness of the first ring plate 22 and the second ring plate 23 are both 15 mm to 25 mm, and the ring width of the first ring plate 22 and the second ring plate 23 are both 60 mm to 90 mm, so as to ensure the wrapping strength of the first ring plate 22 and the second ring plate 23 on the fixing plate 21 and the supporting strength of the first ring plate 22 and the second ring plate 23 on the connecting end 121. In this embodiment, the thickness of the fixing plate 21 is 20 mm, the thickness of the first ring plate 22 and the second ring plate 23 can be set to 20 mm, and the ring width of the first ring plate 22 and the second ring plate 23 can be set to 75 mm.

[0038] In some embodiments, Figure 2 and Figure 4 As shown, a plurality of ribs 24 are also provided around the connection end 121, and the ribs 24 are connected between the connection end 121 and the fixing plate 21. Among them, the ribs 24 can be provided in four numbers, and the four ribs 24 are correspondingly located on the upper side and the lower side of the connection end 121, and the ribs can be connected to the column, the fixing plate, the first ring plate or the second ring plate, and the connection end of the overhanging eaves by welding to improve the structural strength of the connection end 121 in the axial direction of the column 11.

[0039] Furthermore, the thickness of the rib plate 24 is greater than or equal to the third threshold value, and the second threshold value is 5 mm to 8 mm, which reduces the cost while ensuring the support strength. In this embodiment, the rib plate 24 can be set to 10 mm.

[0040] In some embodiments, Figure 5 As shown, the steel structure cantilevered eave assembly also includes at least one reinforcing plate 25, one end of the reinforcing plate 25 is connected to the first ring plate 22 and / or the second ring plate 23, and the reinforcing plate 25 is connected to the connecting end 121 of the cantilevered eave 12 by bolts or welding.

[0041] Furthermore, there are two reinforcing plates 25, which are respectively located on the upper side and the lower side of the connecting end 121, and the length of the reinforcing plates 25 in the extension direction of the overhanging eaves 12 is 1 / 5 to 1 / 3 of the outer diameter of the column 11, thereby reducing the production cost while ensuring the supporting strength. In this embodiment, the diameter of the column 11 is 650 mm, and the length of the reinforcing plates 25 in the extension direction of the overhanging eaves 12 can be 180 mm.

[0042] In this embodiment, there are two reinforcing plates 25, the reinforcing plate 25 located on the upper side of the connection end 121 is connected to the first ring plate 22, and the reinforcing plate 25 located on the lower side of the connection section is connected to the second ring plate 23. The reinforcing plates 25 can be used to support and hold the connection end 121, thereby improving the structural strength of the overhanging eaves 12 in the axial direction of the column 11. Of course, in some embodiments, the steel structure overhanging eaves assembly provided may also only be provided with the reinforcing plate 25 located on the lower side of the connection end 121.

[0043] It should be noted that, in the present embodiment, the column 11, the fixed plate 21, the first ring plate 22, the second ring plate 23 and the cantilevered eaves 12 are all made of Q353B steel, so that the components can be melted and connected better during the welding process to have good connection strength, thereby making the steel structure cantilevered eaves assembly have good structural strength.
