[0036] When in use, the side groove 2 is opened at the end of the cold-drawn steel body 1 in order to reserve an installation position for the assembling block 3, so that the assembling block 3 is embedded in the end of the cold-drawn steel body 1, and the wing plates 4 on both sides of the assembling block 3 are distributed on both sides of the vertical plate of the cold-drawn steel body 1. The bolts 6 are passed through the two wing plates 4 and the bolt holes 5 on the surface of the cold-drawn steel body 1 and then locked, and the wing plates 4 are fixed to the cold-drawn steel body 1, that is, the assembling block 3 is fixed in the side groove 2. And the surfaces of the two side grooves 2 are respectively provided with slots 7 and plug-in blocks 8, and the cold-drawn steel body 1 is provided with two. When the two cold-drawn steel bodies 1 are assembled end to end, the slots 7 and the plug-in blocks 8 are matched and connected; a card slot 9 is provided at one end of the plug-in block 8 extending into the slot 7, and the card slot 9 is a slot body with a circular end. There are two card slots 9, and the two card slots 9 are distributed parallel to each other up and down. An introduction strip 10 is fixed on the surface of the slot 7, and the introduction strip 10 and the card slot 9 correspond one to one. A rubber sleeve 11 is fixed on one end of the introduction strip 10 extending into the card slot 9, and the rubber sleeve 11 is a long strip with a circular end face, and the circular surface diameter of the rubber sleeve 11 is greater than the height of the card slot 9.

[0037] When in use, after the side groove 2 is installed and fixed, the slots 7 and the inserts 8 on the surfaces of the two groups of side grooves 2 are used for pre-limiting when the two cold-drawn steel bodies 1 are assembled end to end, that is, after the two cold-drawn steel bodies 1 are assembled end to end, the inserts 8 are inserted into the corresponding slots 7, and the guide strip 10 extends into the slot 9, and the rubber sleeve 11 is clamped between the guide strip 10 and the slot 9, to achieve traction limiting between the slots 7 and the inserts 8, thereby achieving pre-limiting of the end-to-end splicing of the two groups of cold-drawn steel bodies 1, and enhancing the firmness of the end-to-end splicing of the two cold-drawn steel bodies 1.

[0038] A connecting plate 12 is fixed to the surface of the wing plate 4, and a notch 13 is provided on the surface of the connecting plate 12. A threaded semi-cylinder 14 is fixed to the surface of the notch 13. After the two cold-drawn steel bodies 1 are assembled end to end, the two groups of threaded semi-cylinders 14 are assembled into a threaded stud, and a nut 16 is threaded on the stud. A rubber gasket 15 is fixed to the surface of the notch 13. The rubber gasket 15 is a semicircular ring sheet. The rubber gasket 15 is clamped between the notch 13 and the nut 16 to produce elastic deformation; baffles 18 are movably inserted on the upper and lower sides of the notch 13 to limit the nut 16 after locking.

[0039] When in use, after the two groups of cold-drawn steel bodies 1 are assembled end to end and pre-limited by plugging in the slots 7 and the plug blocks 8, the threaded semi-cylinders 14 on the surfaces of the two groups of connecting plates 12 form threaded studs, the nuts 16 are sleeved and threaded onto the studs, and the nut 16 is tightened to squeeze the rubber gasket 15 to produce elastic deformation, thereby achieving anti-slip limiting of the nut 16.

[0040] Both the front and rear sides of the notch 13 are provided with an embedding groove 17, and the baffle 18 is in a "concave"-shaped plate structure. One end of the baffle 18 with a groove body is inserted into the embedding groove 17, and a rubber support block 19 is fixed in the groove body of the baffle 18, and one end of the rubber support block 19 is fixed in the embedding groove 17; when the rubber support block 19 is in the initial state, the other end of the baffle 18 is pushed out of the embedding groove 17 and blocks the nut 16 to limit the position.

[0041] When in use, in order to further strengthen the fixation of the two groups of cold-drawn steel bodies 1 after being assembled end to end, the anti-slip limit of the nut 16 is realized; that is, the nut 16 is sleeved in front of the stud, the blocking piece 18 is squeezed into the embedding groove 17 with one finger to squeeze the rubber support block 19 to deform, and the other hand is then sleeved on the stud and screwed. When the nut 16 passes over the embedding groove 17, the embedding groove 17 is loosened, and the rubber support block 19 rebounds and pushes one end of the blocking piece 18 out of the embedding groove 17. The protruding part blocks one side of the nut 16 to prevent the nut 16 from escaping from the missing groove 13, thereby ensuring that the nut 16 is stably screwed on the stud.

[0042] The detailed usage process is as follows:

[0043] Connection between cold drawn steel body and assembly blocks

[0044] Installation of side grooves and assembly blocks: Side grooves 2 are provided at both ends of the cold-drawn steel body 1, and these side grooves 2 are used to reserve installation positions for assembly blocks 3. Assembly blocks 3 are embedded in the ends of the cold-drawn steel body 1, and the wing plates 4 on both sides are distributed on both sides of the vertical plate of the cold-drawn steel body 1. Bolt holes 5 are provided on the surfaces of the wing plates 4 and the cold-drawn steel body 1. Bolts 6 are passed through these bolt holes 5 and locked to fix the wing plates 4 on the cold-drawn steel body 1, thereby completing the fixing of the assembly blocks 3 in the side grooves 2.

[0045] End-to-end assembly between cold-drawn steel bodies

[0046] Matching of the slot and the plug: When two cold-drawn steel bodies 1 are assembled end to end, the slot 7 of one cold-drawn steel body 1 is matched and connected with the plug 8 of the other cold-drawn steel body 1 .

[0047] A card slot 9 is provided at one end of the insert block 8 that extends into the slot 7, and a guide bar 10 corresponding to the card slot 9 is fixed on the surface of the slot 7. A rubber card sleeve 11 is fixed on one end of the guide bar 10 that extends into the slot 9, and the diameter of the circular surface of the rubber card sleeve 11 is greater than the height of the slot 9, thereby realizing the traction limit between the slot 7 and the insert block 8, and strengthening the firmness of the end-to-end splicing of the two cold-drawn steel bodies 1.

[0048] Fixing of connecting plate and nut

[0049] Connection between threaded semi-cylinder and nut: A connecting plate 12 is fixed on the surface of the wing plate 4, a notch 13 is clamped on the surface of the connecting plate 12, and a threaded semi-cylinder 14 is fixed on the surface of the notch 13. When the two cold-drawn steel bodies 1 are assembled end to end, the two groups of threaded semi-cylinders 14 are assembled into a threaded stud. A nut 16 is threadedly mounted on the stud, and a rubber gasket 15 is also fixed on the surface of the notch 13. The rubber gasket 15 is clamped between the notch 13 and the nut 16 to produce elastic deformation, thereby preventing the nut 16 from falling off and limiting its position.

[0050] The limiting function of the baffle: the front and rear sides of the notch 13 are provided with an embedding groove 17, and the baffle 18 is a "concave"-shaped plate structure, one end of which is inserted into the embedding groove 17. A rubber support block 19 is fixed in the groove body of the baffle 18, and one end of the rubber support block 19 is fixed in the embedding groove 17. Before the nut 16 is mounted on the stud, the baffle 18 is squeezed into the embedding groove 17 by fingers to squeeze the rubber support block 19 to deform. After the nut 16 is mounted on the stud and screwed, when the nut 16 passes over the embedding groove 17 and the embedding groove 17 is loosened, the rubber support block 19 rebounds and pushes one end of the baffle 18 out of the embedding groove 17, blocking and limiting the nut 16 to prevent the nut 16 from escaping from the notch 13.

[0051] Embodiment 2, based on embodiment 1, proposes a production process of reinforced cold-drawn steel, the process comprising the following methods:
