Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a cold-formed thin-walled steel V-shaped part. Background Technique

[0002] Cold-formed steel is an economical section light thin-walled steel, also known as cold-formed steel section or cold-formed section. Cold-formed steel is the main material for making light steel structures. It has various extremely thin, reasonably shaped and complex sections that cannot be produced by hot rolling. Compared with hot-rolled steel sections, under the condition of the same cross-sectional area, the radius of gyration can be increased by 50% - 60%, and the moment of inertia of the cross-section can be increased by 0.5 - 3.0 times. Therefore, the material strength can be more reasonably utilized; compared with ordinary steel structures, about 30% - 50% of steel can be saved. In some cases, the steel consumption of cold-formed steel structures is equivalent to that of reinforced concrete structures under the same conditions. It is an economical section steel.

[0003] Chinese Patent with publication number CN221144935U discloses a cold-formed thin-walled steel V-shaped part, belonging to the technical field of connectors.

[0023] Please refer to Figures 1-3 , this embodiment provides a cold-formed thin-walled steel V-shaped part, including a cold-formed thin-walled steel V-shaped part body 100. Fixing sleeves 102 are provided at the same positions at both ends of the cold-formed thin-walled steel V-shaped part body 100. A connecting member for increasing the torsional resistance of the cold-formed thin-walled steel V-shaped part body 100 is connected between the fixing sleeves 102. Connecting holes 104 for connecting square tubes are opened on both the upper and lower sides of the cold-formed thin-walled steel V-shaped part body 100;

[0024] The connecting piece includes fixing columns 303 fixedly installed on the opposite sides of two groups of fixing sleeves 102. A connecting plate 300 is slidably connected between the two groups of fixing columns 303. Arc-shaped notches 305 corresponding to the surfaces of the fixing columns 303 are formed at both ends of the connecting plate 300. Fixing members for fixedly connecting the fixing columns 303 are arranged on both sides of the connecting plate 300 and above the arc-shaped notches 305. Through the arrangement of the connecting piece, the cold-formed thin-walled steel V-shaped part body 100 is supported without grooving, thereby improving the support strength and torsional resistance of the cold-formed thin-walled steel V-shaped part body 100, greatly extending the service life of the V-shaped part, and facilitating the staff to assemble it. The assembly process is very convenient and fast, thus improving the practicability.

[0025] Further, the fixing member includes connecting discs 302 fixedly connected to both ends of the connecting plate 300. Threaded holes 304 are formed on the top surfaces of the two groups of fixing columns 303. Bolts 301 are slidably inserted into the surfaces of the connecting discs 302. One ends of the two groups of bolts 301 respectively penetrate through the connecting discs 302 and are threadedly connected to the inner cavities of the corresponding threaded holes 304. Through the arrangement of the fixing member, the arc-shaped notches 305 at both ends of the connecting plate 300 are slidably connected to the surfaces of the corresponding fixing columns 303, and the connecting discs 302 at both ends of the connecting plate 300 are abutted against the top surfaces of the fixing columns 303. Then, the two groups of bolts 301 are taken out and respectively penetrate through the corresponding connecting discs 302 and are threadedly connected to the inner cavities of the corresponding threaded holes 304, so that it is very convenient and fast for the staff to fix it, and has a good fixing effect.

[0026] Furthermore, a limiting groove 200 is fixedly connected to the top of one side of the connecting plate 300. The corners of the limiting groove 200 are all chamfered. Through the arrangement of the limiting groove 200, when the cold-formed thin-walled steel V-shaped part body 100 is connected to the pipe, the pipe is placed in the inner cavity of the limiting groove 200 to limit and support the pipe, so that the staff does not need to hold the pipe all the time, thereby greatly reducing the labor intensity of the staff.

The anti-torsion block 103 is arranged in a cross shape. Reinforcing ribs 101 are fixedly connected to both sides of the cold-formed thin-walled steel V-shaped part body 100. Through the arrangement of the anti-torsion block 103 and the reinforcing ribs 101, the structural strength of the cold-formed thin-walled steel V-shaped part body 100 is improved. Moreover, the anti-torsion block 103 is arranged in a cross shape, which can effectively disperse and bear the stress brought by torque, thereby improving the overall anti-torsion strength.

[0030] Working principle;

[0031] First, take out the connecting plate 300, make the arc-shaped notches 305 at both ends of the connecting plate 300 slide on the surface of the corresponding fixed column 303, and make the connecting disks 302 at both ends of the connecting plate 300 abut against the top surface of the fixed column 303. Then, take out two groups of bolts 301 and pass them through the corresponding connecting disks 302 and thread them into the inner cavity of the corresponding threaded holes 304 to fix the connecting plate 300. When the pipe needs to be fixed, first place the pipe in the limiting groove 200 for preliminary positioning of the pipe. Use screws to sequentially penetrate the pipe and insert them into the connecting holes 104, and use nuts to fix them. At this time, tighten the screw rod 201 so that one end of the screw rod 201 abuts against the surface of the pipe to further fix the pipe. Then, use screws and nuts to fixedly connect the bottom columns of the cold-formed thin-walled steel V-shaped part body 100 together.
