[0026] like Fig.10As shown, four combined bolts 603 are slidably connected to the connecting seat 301 at the upper end of the main beam 3.

[0027] As Figure 7 , Figure 8 shown, a side beam 302 is fixedly connected to the side of the main beam 3 by welding. Four reinforcing ribs 9 are also fixedly connected between the side beam 302 and the main beam 3. Four circular through-holes are provided at the other end of the side beam 302.

[0028] As Figure 8 , Fig. 9 shown, the connecting mechanism 7 includes two support members 701. The cross-section of the support member 701 is in a C shape. The support member 701 is slidably connected to the side beam 302. The two support members 701 are arranged on both sides of the side beam 302.

A cross beam 8 is slidably connected to the outer sides of the two support members 701. Four circular through-holes are provided at the end of the cross beam 8. The connecting bolts 702 are slidably connected in the circular through-holes at the end of the cross beam 8.

[0029] Working principle: When installing this steel structure connecting member, in the first step, a cement pile 101 is poured at the designated position, and the fixing mechanism 1 and the adjusting mechanism 2 are installed, that is, the adjusting nut 202 and the expansion nut 103 are installed during the pouring of the cement pile 101. In the second step, the main beam 3 is hoisted into the cement pile 101 by a crane. First, the position of the main beam 3 is adjusted through the adjusting mechanism 2, and then the main beam 3 is fixedly connected to the cement pile 101 through the fixing mechanism 1. In the third step, the two longitudinal beams 4 are fixedly connected to the main beam 3 through the locking mechanism 5. In the fourth step, the connecting mechanism 7 is installed between the main beam 3 and the cross beam 8. In the fifth step, the support beam 6 is installed at the upper end of the main beam 3. At this time, the overall installation of the steel structure connecting member is completed.

[0030] When the crane hoists the main beam 3 into the cement pile 101, the position of the main beam 3 is adjusted through the adjusting mechanism 2, and the adjusting bolt 203 is rotated with a wrench. Under the action of the adjusting nut 202, the adjusting bolt 203 rotates to push the adjusting block 201 to slide to one side. The adjusting mechanism 2 on both sides of the connecting seat 301 is rotated in the opposite direction with a wrench, so that the connecting seat 301 can be moved to one side, so that the threaded hole of the expansion nut 103 corresponds to the opening on the connecting seat 301, so as to insert the pull rod 102. When the position adjustment of the connecting seat 301 is completed, the adjusting bolt 203 is rotated inwardly, and the adjusting bolt 203 drives the adjusting block 201 to move toward the connecting seat 301 at the same time, thereby fixing the connecting seat 301. Since the cross-section of the adjusting block 201 is L-shaped, the adjusting block 201 can fix the connecting seat 301 in the cement pile 101 and limit the upper surface of the connecting seat 301 at the same time, so as to prevent the main beam 3 from tilting, thereby affecting the construction progress and installation accuracy.

[0031] After the adjusting mechanism 2 has completed the position adjustment of the main beam 3, the main beam 3 is fixedly connected to the cement pile 101 through the fixing mechanism 1. After the position of the main beam 3 is calibrated using the adjusting mechanism 2, the pull rod 102 is inserted into the holes corresponding to the connecting seat 301 and the expansion nut 103, the pull rod 102 is rotated to make the pull rod 102 and the expansion nut 103 be threadedly connected, and an anti-loosening pad 104 is installed above the connecting seat 301 and on the outside of the pull rod 102, and the fixing nut 105 is screwed into the pull rod 102. The lower surface of the anti-loosening pad 104 is fixedly connected with a plurality of tooth-shaped protrusions, and then the fixing nut 105 is tightened above the anti-loosening pad 104 using a wrench. When the fixing nut 105 is tightened, the tooth-shaped protrusions on the lower surface of the anti-loosening pad 104 can be embedded in the surface of the connecting seat 301, forming a certain friction force, thereby increasing the anti-loosening ability of the fixing nut 105, and preventing the fixing nut 105 from loosening, resulting in failure of fixation and tilting of the main beam 3, thereby forming a safety hazard.

[0032] When the two longitudinal beams 4 are fixedly connected to the main beam 3 through the locking mechanism 5, the two longitudinal beams 4 are symmetrically inserted into the main beam 3. Push the locking handle 503 to slide inwards. The inward sliding of the locking handle 503 drives the limit block 516 to slide inwards. The inward sliding of the locking handle 503 pushes the rotating plate 505 to slide inwards. The inward sliding of the rotating plate 505 pushes the locking wedge 507 on one side to slide inwards. The inward sliding of the locking wedge 507 drives the two guide blocks 508 to slide in the T-shaped sliding grooves of the main beam 3 and the limit frame 509. The locking wedge 507 on one side slides inwards, pushing one end of the two linkage rods 514 to move in the opposite direction. Under the action of the rotating shaft, one end of the two linkage rods 514 slides in the opposite direction, driving the two sliding blocks 513 to slide in the opposite direction. The two sliding blocks 513 slide in the opposite direction to stretch the tension spring 515. Under the action of the rotating shafts at the other ends and the middle rotating shaft of the two linkage rods 514, the other ends of the other two linkage rods 514 start to slide in the opposite direction, driving the other locking wedge 507 to slide inwards. The two locking wedges 507 move towards each other, pushing the locking plate 502 to slide forward. The forward sliding of the locking plate 502 drives the reset rod 510 to slide forward. The forward sliding of the reset rod 510 drives the reset plate 511 to slide forward. The forward sliding of the reset plate 511 compresses the reset spring 512. The locking plate 502 slides forward, passing the locking column 501 through the circular through hole at the end of the longitudinal beam 4 and inserting it into the main beam 3. When the limit block 516 passes through the square sliding groove opened on the limit plate 504, twist the locking handle 503 90 degrees to one side, rotating from the vertical direction to the horizontal direction. The other end of the locking handle 503 drives the rotating plate 505 to rotate simultaneously. The locking bolt 506 slides in the arc-shaped sliding groove of the rotating plate 505. At this time, the limit plate 504 limits the limit block 516. At this time, the locking mechanism 5 fixedly connects the two longitudinal beams 4 to the main beam 3. The locking mechanism 5 can realize the quick connection and disassembly of the longitudinal beam 4 and the main beam 3, reducing the manufacturing and transportation costs of the steel structure connection components, optimizing the connection method, and reducing the labor and time costs.

[0033] When installing the connecting mechanism 7 between the main beam 3 and the cross beam 8, after the main beam 3 is installed, first use a crane to lift the cross beam 8 to a height flush with the side beam 302. Then install the support members 701 on both sides of the side beam 302 and the cross beam 8. Subsequently, pass the connecting bolt 702 sleeved with the lock washer 703 through the side beam 302, the main beam 3, and the support member 701. Sleeve the lock washer 703 on the other end of the connecting bolt 702, and use a wrench to tighten the connecting nut 704. After symmetrically tightening the eight connecting nuts 704, at this time, the side beam 302 and the cross beam 8 are fixedly connected, and the installation of the connecting mechanism 7 is completed. The cross-section of the support member 701 is in a U shape. When the side beam 302 and the cross beam 8 are stressed, the main stress-bearing parts are the two support members 701, increasing the strength and load-bearing capacity of the steel structure connection components.

[0034] When installing the supporting beam 6 at the upper end of the main beam 3, after the main beam 3 is installed, first use a crane to lift the supporting beam 6 to the top of the main beam 3, align the support 601 with the connecting seat 301 at the upper end of the main beam 3, pass the combined bolt 603 with the combined washer 604 through the support 601 and the connecting seat 301 at the upper end of the main beam 3, then set the combined washer 604 on the outer side of the lower end of the combined bolt 603, and use a wrench to symmetrically tighten the combined nut 602. At this time, the fixed connection between the supporting beam 6 and the main beam 3 is completed.

[0035] When it is necessary to dismantle the steel structure connecting member and release the fixing of the locking mechanism 5 on the longitudinal beam 4 and the main beam 3, the locking handle 503 is rotated from the horizontal direction to the vertical direction, and the locking handle 503 is pulled outward to release the limit plate 504 from the limit of the limit block 516, and the tension spring 515 releases the pressure and begins to shrink. The tension spring 515 pulls the sliding blocks 513 at both ends to slide toward each other. The sliding of the two sets of sliding blocks 513 towards each other drives one end of the two sets of linkage rods 514 to slide towards each other. Under the action of the rotating shaft at the other end of the linkage rod 514 and the middle rotating shaft, one end of the two sets of linkage rods 514 slides towards each other. The two locking wedges 507 are driven to slide in opposite directions, and the return spring 512 releases the pressure to push the return plate 511 to slide backward. The return plate 511 slides backward and pushes the return rod 510 to slide backward. The return rod 510 slides backward and drives the locking plate 502 to slide backward. The locking plate 502 slides backward and drives the locking column 501 to disengage from the main beam 3 and the two longitudinal beams 4. At this time, the locking mechanism 5 releases the fixation of the two longitudinal beams 4 and the main beam 3. When the locking column 501 slides backward and becomes stuck, the return rod 510 can be manually pulled to force the locking plate 502 and the locking column 501 to reset.

[0036] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
