Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a steel structure with surface treatment of multi-element alloy co-penetration. Background Art

[0002] Steel structure is a structure composed of steel materials. It is one of the most important types of modern building structures. The materials used in the steel structure are mainly steel beams, steel columns, steel trusses and other hooks made of steel sections and steel plates. The various hooks of the steel structure are usually connected by welding or bolts and rivets. In the steel structure hooks, in order to improve the surface corrosion resistance and strength of the steel structure, galvanizing and anti-corrosion materials will be sprayed on the surface of the steel structure. Surface treatment multi-alloy co-infiltration technology is one of the modern ways to enhance the surface strength of steel structures. Multi-alloy co-infiltration steel structure refers to the steel structure being placed in a penetrant of at least two elements to be infiltrated.

[0003] During the assembly process of the multi-alloy co-diffusion steel structure, when the steel body is insufficient in height, the steel body will still be connected by welding or riveting bolts. However, in the ordinary bolt connection method, during the tightening and fixing process of the bolts, the nut or the screw tip will rub against the surface of the fastening position of the steel structure, causing the multi-alloy after surface treatment of the steel structure to separate from the steel body, making the bolt connection position prone to rust and damage.

[0004] Therefore, a surface treatment is needed for a multi-element alloy co-penetration steel structure to solve the above problems. Utility Model Content

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1

[0022] like Figure 1-4 As shown, the utility model proposes a surface treatment of a multi-alloy co-penetration steel structure, including: an adapter seat 1, an H-shaped steel body 2 is penetrated inside the upper and lower ends of the adapter seat 1, the outer surface of the H-shaped steel body 2 is fitted on the inner wall of the adapter seat 1, and two symmetrical groups of fastening structures 3 are fixed on the upper and lower sides of the outer walls of both sides of the adapter seat 1, the fastening structure 3 is fitted and clamped with the H-shaped steel body 2, and the position where the fastening structure 3 is connected to the H-shaped steel body 2 is penetrated by two symmetrical groups of off-surface screws 4, the inner side of the off-surface screw 4 includes a facing retaining ring 5 fitted on the outer surface of the adapter seat 1, and a bolt tube 6 is fixedly connected inside the facing retaining ring 5, and the bolt tube 6 is penetrated inside the adapter seat 1, the H-shaped steel body 2, and the fastening structure 3, a locking screw 7 is penetrated inside the other end of the bolt tube 6, and the other end of the locking screw 7 passes through the outside of the bolt tube 6, and the locking nut 8 is screwed on one end of the locking screw 7 located on the outside of the bolt tube 6.

[0023] The inner side of the fastening structure 3 includes a two-way drive box 9, which is fixed on both sides of the outer wall of the adapter 1, and the two-way drive box 9 is provided with two groups fixed on the upper and lower sides of the adapter 1. The design of multiple groups of two-way drive boxes 9 can clamp and lock all the positions connected to the H-shaped steel body 2 one by one at the same time, so as to ensure the connection strength of the H-shaped steel body 2 before being fixed.

[0024] A bidirectional screw 10 is passed through the inner side of the bidirectional drive box 9, and one end of the bidirectional screw 10 extends to the outer side of the end of the bidirectional drive box 9. The bidirectional screw 10 can control the L-shaped driven rods 12 on both sides to move in both directions by rotating the screw in one direction, thereby completing the clamping of the H-shaped rigid body.

[0025] A fitting locking plate 13 is fixed to one end of the L-shaped follower rod 12 away from the bidirectional screw 10. The fitting locking plate 13 fits with the outer surface of the H-shaped steel body 2. The fitting locking plate 13 has a larger area for fitting and connecting with the H-shaped steel body 2, which can enhance the firmness of the connection between the H-shaped rigid body and the adapter 1 and the fastening structure 3.

[0026] A hexagonal driving block 14 is fixed to one end of the bidirectional screw 10 located outside the bidirectional driving box 9, and a driving crank 15 is provided on the outside of the hexagonal driving block 14. A hexagonal groove 16 is provided at one end of the driving crank 15 connected to the hexagonal driving block 14. The hexagonal groove 16 cooperates with the hexagonal driving block 14 for driving connection. The driving crank 15 can quickly cooperate with the hexagonal driving block 14 to complete the driving of the bidirectional screw 10, thereby improving the speed of clamping and fixing the H-shaped rigid body and the adapter 1, reducing the connection time of workers, and improving the work safety of workers.

[0027] In this embodiment, when connecting the steel structure whose surface has been treated with multi-alloy co-penetration, the two ends of the H-shaped rigid body are connected to the adapter seat 1, and then the driving crank 15 is rotated to drive the bidirectional screw 10 to rotate, so that the L-shaped driven rod 12 connected to the outside of the bidirectional screw 10 moves to both sides, and the fitting locking plate 13 connected to the end of the L-shaped driven rod 12 is fitted with the H-shaped steel body 2 to complete the fitting, clamping and fixing of the H-shaped steel body 2. When all the fastening structures 3 are connected to the H-shaped steel body 2, the fitting locking plate 13 can be fixed to the H-shaped steel body 2 and the bolts of the adapter seat 1.

[0028] When connecting the H-shaped rigid body and the adapter seat 1 by bolts, first, the bolt tube 6 inside the off-surface screw 4 is passed through the inner side of the connecting hole connecting the adapter seat 1 to the H-shaped rigid body. When the bolt tube 6 is completely passed through the adapter seat 1 and the H-shaped rigid body and the fitting locking plate 13, the facing retaining ring 5 will fit on the outer surface of the adapter seat 1. At this time, the locking screw 7 inside the off-surface screw 4 is passed through the bolt tube 6 inside the fitting locking plate 13, and the other end of the locking screw 7 is allowed to pass through the inside of the facing retaining ring 5. At this time, the locking nut 8 can be threadedly screwed on the outside of the locking screw 7. After the locking nut 8 and the locking screw 7 are rotated and tightened, the fixation of the adapter seat 1 and the H-shaped steel body 2 can be completed.

[0029] It should be noted that: when the off-surface bolts connect the adapter 1 to the H-shaped rigid body, rotating the locking nut 8 will only contact the facing retaining ring 5, and will not generate friction with any position of the adapter 1 and the H-shaped rigid body, and will not cause friction damage to any position on the outer surface of the adapter 1 and the H-shaped rigid body.

[0030] Embodiment 2

[0031] like Figure 1-4As shown, based on the first embodiment, a symmetrical L-shaped follower rod 12 is sleeved on the outside of the bidirectional screw 10, and the outer surface of the L-shaped follower rod 12 slides on the inner wall of the bidirectional drive box 9, and a barrier ring 11 is fixed between the L-shaped follower rods 12 in the middle of the bidirectional screw 10.

[0032] The blocking switch in the middle of the bidirectional screw rod 10 can block the two L-shaped driven rods 12 to prevent the L-shaped driven rods 12 from being disengaged from the threads when moving to the middle of the bidirectional screw rod 10, thereby ensuring the contraction stability of the L-shaped driven rods 12.

[0033] A finger locking piece 17 is fixed at the position where the inner wall of the fitting locking piece 13 is connected to the locking screw 7. The finger at the end of the locking screw 7 is embedded in the inner side of the finger locking piece 17. The design of the finger locking piece 17 can fix the finger at the end of the locking screw 7. The locking screw 7 can be tightened by only turning the locking nut 8, which facilitates the tightening of the locking screw 7 and improves the connection efficiency.

[0034] It should be noted that the locking screw 7 is composed of a finger and a threaded rod, and the threaded rod is fixed at the center of the side of the finger.
