Description

Technical Field

[0001] The utility model belongs to the technical field of building steel structures, in particular to a connection structure of a double-angle steel combined section and a node plate. Background Art

[0002] The double-angle steel composite section can be combined and designed according to different stress conditions to meet the building structure's requirements for bearing capacity and stiffness, while the node plate connection can easily connect different components together to form a stable structural system.

[0003] When steel structure beams are installed, the double angle steel composite section and the node plate are connected by welding. When the double angle steel is subjected to excessive pressure, it may be deformed and the connection with the node plate will be separated. At this time, the double angle steel and the node plate need to be re-fixed and connected. Therefore, we need to design a connection structure between the double angle steel composite section and the node plate, and fix the double angle steel and the node plate through a bolt rope clamp connection structure. After the bolts are tightened, the friction between the contact surfaces can resist part of the external force, and the bolts themselves can also withstand shear force. This connection method is easy to install and disassemble, and has high connection strength, which can ensure the reliability and stability of the double angle steel and node plate structure during long-term use.

[0025] Hereinafter, embodiments of the connection structure of the double-angle steel composite section and the gusset plate of the present invention will be described with reference to the accompanying drawings.

[0026] Figure 1-6The utility model shows a connection structure of a double-angle steel composite section and a node plate in an embodiment of the present invention, which includes two obliquely symmetrical node plates 2 fixedly connected to the inner cavity of the steel structure beam 1. A plurality of bolts 3 are provided on the surface of the steel structure beam 1. A fixing plate 4 is fixedly connected to the front and rear sides of the node plate 2 on the left side. The fixing plate 4 is fixedly connected to the node plate 2 by bolts 3. The surfaces of the two fixing plates 4 are sleeved with mounting plates 5. The two mounting plates 5 are fixedly connected to the steel structure beam 1 by bolts 3. Through the coordinated use of the fixing plates 4 and the mounting plates 5, the fixing plates 4 play a role of limiting the position of the mounting plates 5 on the fixing plates 4 when clamping the node plates 2, ensuring that the fixing plates 4 will not loosen when clamping the node plates 2, thereby improving the node plate 2. For stability during use, the fixing plate 4 passes through the right side of the steel structure beam 1 and is fixedly connected to the node plate 2. Two opposite double angle steels 6 are provided on the opposite side of the two node plates 2. The surfaces of the double angle steels 6 and the left and right sides of the node plates 2 are penetrated by U-shaped clips 7. The rear side of the U-shaped clip 7 is provided with a clamping plate 8. The clamping plate 8 fits tightly with the inner wall of the rear double angle steel 6. The U-shaped clip 7 and the clamping plate 8 fit tightly with the node plate 2 and the double angle steel 6 through bolts 3. The right side of the inner cavity of the steel structure beam 1 is fixedly connected with a support plate 9. Reinforcements 10 are provided on the front and rear sides of the right node plate 2. The bottoms of the two reinforcements 10 are fixedly connected to the support plate 9 by bolts 3. The two reinforcements 10 are fixed to the node plate 2 by bolts 3. The top of the lower base plate 11 is fixedly connected with the connecting column 13, and the top of the inner cavity of the steel structure beam 1 is provided with an upper plate 14, and the upper plate 14 is fixedly connected to the steel structure beam 1 by bolts 3. The front and rear sides of the bottom of the steel structure beam 1 are fixedly connected with side baffles 12, and the two sides of the side baffles 12 facing each other are tightly fitted with the double angle steel 6. Through the setting of the side baffles 12, the side baffles 12 can clamp the double angle steel 6 when the two double angle steels 6 are in use, thereby avoiding the phenomenon of the two double angle steels 6 falling off when combined, ensuring that the double angle steels 6 will not fall off, and improving the stability of the two double angle steels 6 during use. Fixed connection, the bottom of the upper top plate 14 is fixedly connected to the connecting column 13, and a support frame 15 is provided at the bottom of the two double angle steels 6. The top of the support frame 15 is fixedly connected to the two double angle steels 6 by two symmetrical bolts 3, and the bottom of the support frame 15 is fixedly connected to the steel structure beam 1 by multiple bolts 3. Through the setting of the support frame 15, the bottom of the double angle steel 6 is limited, ensuring that the double angle steel 6 will not be deformed or broken during use, thereby improving the stability of the bottom of the double angle steel 6 during use. The surfaces of the multiple bolts 3 are threaded with nuts 16, the node plate 2 and the double angle steel 6 are provided with round holes for the U-shaped clips 7 to pass through, and the surfaces of the two mounting plates 5 are provided with square grooves for the fixing plates 4 to pass through.

[0027] Working principle: When the present invention is used, the user fixes the two mounting plates 5 to the left side of the steel structure beam 1 by means of bolts 3, and then the fixing plate 4 is passed through the left side of the inner cavity of the steel structure beam 1 to clamp the node plate 2. The square groove opened in the inner cavity of the mounting plate 5 ensures that the fixing plate 4 will not loosen when clamping the node plate 2. The bolts 3 pass through the surfaces of the fixing plate 4 and the left node plate 2 to fix the node plate 2 and the fixing plate 4, so that the node plate 2 is stable in the steel structure beam 1. Then the reinforcement 10 on the front and rear sides of the right node plate 2 is fixedly connected by bolts 3. At the same time, the right node plate 2 and the steel structure beam 1 will not loosen when connected. Then the two double angle steels 6 are fitted to the front and rear sides of the node plate 2, and then the U-shaped clip 7 is passed through the two double angle steels. 6 and the surface of the node plate 2, pass the clip plate 8 through the rear side of the U-shaped clip 7, so that the clip plate 8 is tightly fitted with the rear double angle steel 6, and the two bolts 3 are rotated on the surface of the U-shaped clip 7, and the U-shaped clip 7 and the clip plate 8 are fixedly connected to the node plate 2 and the double angle steel 6. Then the lower bottom plate 11 and the two side baffles 12 fit the two double angle steels 6, so that the upper top plate 14 is fixedly connected to the steel structure beam 1 through the bolts 3, and then the connecting column 13 plays a top support effect on the lower bottom plate 11 and the upper top plate 14. Due to the support of the support frame 15 on the bottom of the two double angle steels 6, the bottom of the two double angle steels 6 is fixedly connected to the steel structure beam 1. Finally, the steel structure beam 1 is fixedly connected to the node plate 2 and the double angle steel 6, and the two double angle steels 6 will not break.

[0028] To sum up: the connection structure of the double-angle steel combined section and the node plate, through the coordinated use of bolts 3, U-shaped clips 7 and clip plates 8, allows the double-angle steel 6 and the node plate 2 to be installed in the inner cavity of the steel structure beam 1, and then the node plate 2 and the double-angle steel 6 can be firmly installed in the inner cavity of the steel structure beam 1, and then through the coordinated use of side baffles 12, connecting columns 13 and supporting frames 15, the two double-angle steels 6 have better stability during use, and will not deform or bend, so that the double-angle steel and the node plate can be fixedly connected through the bolt rope clamp connection structure. After the bolts are tightened, the friction force generated between the contact surfaces can resist part of the external force, and the bolts themselves can also withstand shear force. This connection method is easy to install and disassemble, and has high connection strength, which can ensure the reliability and stability of the double-angle steel and node plate structure during long-term use.
