[0027] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail in conjunction with the accompanying drawings.

[0028] The present utility model provides a safe steel structure joint member. The I-beam is inserted into the left and right ends of the support frame. After insertion, it is locked and fixed by fixing bolts. The support frame is used for anti-deviation limit to prevent the I-beam from shaking and causing the fixing bolts to loosen. The fixing bolts are used to connect the I-beam to prevent the I-beam from falling off the support frame and improve the connection stability. Please refer to Figures 1 - 4 , including: a connecting piece 100 and a steel structure beam 200.

[0029] The connecting piece 100 includes a support frame 110 and fixing bolts 120. Fixing bolts 120 are provided at both the left and right ends of the support frame 110;

[0030] Among them, the support frame 110 is a rectangular frame, and the fixing bolts 120 are symmetrically and evenly distributed at both ends of the support frame 110.

[0031] The steel structure beam 200 is inserted at both ends of the support frame 110. The steel structure beam 200 includes an I-beam 210 and fixing holes 220. The I-beams 210 are respectively inserted on both sides of the support frame 110. Fixing holes 220 are provided at one end of the I-beam 210 located inside the support frame 110, and the fixing holes 220 are screwed with fixing bolts 120;

[0032] Among them, the I-beam 210 is fitted with the inner wall of the support frame 110. The I-beam 210 is inserted into the support frame 110, and the support frame 110 is used to prevent the I-beam 210 from deviating and being limited, so as to avoid the loosening caused by the shaking of the I-beam 210.

[0033] To further improve the connection stability, pulling holes 230 are provided at one end of the two I-beams 210 located outside the support frame 110, and a pulling mechanism 300 is connected between the two pulling holes 230. Specifically, the pulling mechanism 300 includes a double-headed screw rod 310, connecting seats 320 and pulling bolts 330. Connecting seats 320 are provided at both ends of the double-headed screw rod 310, and pulling bolts 330 connected to the pulling holes 230 are provided on the connecting seats 320;

[0034] Among them, the connecting seat 320 is connected to the I-beam 210 through a pulling bolt 330. By rotating the double-headed screw rod 310, the two connecting seats 320 are driven to approach each other, so that the two I-beams 210 approach each other to complete the pulling.

[0035] Since the double-headed screw rod 310 needs to be rotated, for this reason, a gear 340 is provided at the center of the double-headed screw rod 310, a chute 130 is opened on the support frame 110, and a rack 400 meshing with the gear 340 is inserted into the chute 130;

[0036] Pull the rack 400, drive the gear 340 to rotate through the rack 400, and use the gear 340 to synchronously drive the double-headed screw rod 310 to rotate, so that the two double-headed screw rods 310 can be rotated at the same time. After use, just pull out the rack 400.

[0037] To avoid structural loosening, double nuts are provided on both sides of the double-headed screw rod 310. The double nuts are connected to the connecting seat 320 and are locked by the double nuts to prevent the double-headed screw rod 310 from rotating under shaking and causing structural loosening.

[0038] To facilitate pulling the rack 400, pull rings are provided at the top and bottom of the rack 400, and the rack 400 is pulled through the pull rings.

[0039] To facilitate the detachment of the connecting seat 320 from the double-headed screw rod 310, stop blocks are provided at both ends of the double-headed screw rod 310 to provide anti-detachment limit.

[0040] During specific use, the I-beams 210 are respectively inserted into both sides of the support frame 110. After insertion, they are connected to the fixing holes 220 through the fixing bolts 120 to complete the connection between the support frame 110 and the I-beams 210. Then, the connecting seat 320 is connected to the I-beam 210 through the pulling bolt 330. The rack 400 is pulled, and the gear 340 is driven to rotate by the rack 400. The double-headed lead screw 310 is synchronously driven to rotate by the gear 340, driving the two connecting seats 320 to approach each other, so that the two I-beams 210 approach each other to complete the pulling. The double nuts are used for locking to prevent the double-headed lead screw 310 from rotating under shaking and causing the structure to loosen.

[0041] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
