This is the steel structure building system that is generally favored by industry insiders. At present, steel structure buildings in the market are mostly fixed to concrete walls with expansion bolts.

[0003] A connection device for a concrete exterior wall and a steel structure building disclosed in a patent application with reference publication number CN111809741B includes a wall, a connection frame is installed on one side of the wall, a fixing groove is opened in the wall near the connection frame, and mounting rod grooves are penetrated on both sides of the wall near the fixing groove, wherein a mounting rod is fixed on one side of the connection frame near the mounting rod groove, and an end of the mounting rod away from the connection frame penetrates the mounting rod groove and enters the interior of the fixing groove, and grouting ports are penetrated in the connection frame and the mounting rod. In the connection device for a concrete exterior wall and a steel structure building, after the connection frame drives the mounting rod to penetrate the interior of the mounting rod groove and enter the interior of the fixing groove, concrete slurry is injected into the fixing groove through the grouting port, and when the concrete slurry solidifies, the mounting rod and the concrete slurry are solidified into one body to form a T-shaped block, so as to prevent the mounting rod from moving out of the interior of the fixing groove, and facilitate the fixed connection between the connection frame and the wall.

[0004] In the above-mentioned connecting device, the connecting device is fixed to the concrete wall by means of a post-installation rod and concrete slurry coagulation, but the connecting device is not fixed to the wall in a T-shape, and the concrete slurry coagulation method requires a long time to wait for the concrete to solidify, during which time it is impossible to erect and install the device, which affects the efficiency of the installation; and after installation, the angle of the connecting device cannot be adjusted, and when deflection occurs during the installation process, it cannot be adjusted, and for some connections with an inclined angle, it cannot be adjusted; after the installation of the steel parts and the connecting device, they are only simply fixed and supported, and cannot be supported by other means to ensure their stability.

[0049] During the specific implementation, firstly, an installation slot 1001 and a limiting slot 1002 are opened or reserved on the building wall 1, and the positioning block 3 fixedly connected to one side of the fixed support plate 2 is inserted into the installation slot 1001, and the positioning block 3 is stretched to extend into the limiting slot 1002 to form a limit, and the building wall 1 and the fixed support plate 2 are fixed by the first bolt 311; then, by starting the first hydraulic telescopic rod 7, the first hydraulic telescopic rod 7 is telescopically pushed to push the positioning installation frame 4 inside the fixed mounting seat 6 to deflect the angle, thereby adjusting the installation angle of the adaptive steel structure 5; then, through the lifting equipment, one end of the steel structure 5 is inserted into the positioning installation frame 4, and the steel structure 5 pushes the moving plate 9 to drive the traction member to pull the positioning member, so that the positioning plate 101 in the positioning member is inserted into the mounting groove 501, and the mounting plate 502 is fixed to the positioning plate 101 by the second bolt 106, thereby achieving a more convenient and stable connection between the building wall 1 and the steel structure 5.

[0050] like Figure 3 to Figure 4 and Figure 7 As shown, in this embodiment, the support member includes a sliding rack 304 arranged inside the side groove 302, the sliding rack 304 passes through the side of the positioning block 3 away from the fixed support plate 2 and is slidably connected to the positioning block 3, the outer side of the sliding rack 304 is meshed with a transmission gear 308, the inner side of the transmission gear 308 is fixedly connected with a rotating rod 306, the rotating rod 306 is arranged inside the side groove 302 and is rotatably connected to the positioning block 3, and the outer side of the rotating rod 306 is fixedly connected with a deflection plate 307.

A pushing plate 301 is fixedly connected between the two sliding racks 304. A placement groove is provided on one side of the positioning block 3, and the pushing plate 301 is adapted to the placement groove. Two first bolts 311 are provided on the outer side of the fixed support plate 2, and the two first bolts 311 are sequentially penetrated through the fixed support plate 2, the building wall 1 and the deflection plate 307, and a threaded groove is provided on the outer side of the deflection plate 307, and the threaded groove is threadably adapted to the first bolt 311.

[0052] In specific implementation, most of the existing connections between the building wall 1 and the steel structure 5 are directly fixed with expansion bolts, which are often not stable enough during connection. Therefore, the device inserts the positioning plug 3 fixedly connected to one side of the fixed support plate 2 into the installation slot 1001, and pushes the push plate 301 to move by contacting the inner side of the wall through the push plate 301. The push plate 301 pushes the sliding rack 304 to move inside the side groove 302. At this time, the sliding rack 304 drives the meshing transmission gear 308 to rotate, and the rotation of the transmission gear 308 drives the fixedly connected rotating rod 306 to rotate, and the rotating rod 306 drives the fixedly connected deflection plate 307 to rotate The deflection plate 307 rotates to the inside of the limiting groove 1002, so that the deflection plate 307 is stuck in the limiting groove 1002 to form a T shape. At this time, the first bolt 311 is drilled into the outside, so that the first bolt 311 passes through the fixed support plate 2, the positioning plug 3 and the deflection plate 307 in sequence, so as to ensure the fixed installation of the fixed support plate 2. It is worth mentioning that a hole can be opened in advance on the outside of the fixed support plate 2 so that the threaded groove on the deflection plate 307 is aligned with the first bolt 311 for easy positioning. At the same time, a ratchet 309 is provided on the outside of the transmission gear 308, and the transmission gear 308 is limited by the ratchet 309, so that the deflection plate 307 remains stable after rotation.

[0053] like Figure 1 and Figures 6 to 9 As shown, embodiment 2: the support member includes a rotating gear 801 fixedly connected to the outer side of the rotating shaft 401, the outer side of the rotating gear 801 is meshedly connected with a driven gear 802, the driven gear 802 is rotatably connected to the fixed mounting seat 6, the outer side of the driven gear 802 is fixedly connected with a winding disk 803, the outer side of the fixed support plate 2 is fixedly connected with a support plate 805, the outer side of the support plate 805 is rotatably connected with a first pulley 804, the outer side of the positioning mounting frame 4 is fixedly connected with a fixed shaft 807, the outer side of the winding disk 803 is wound and fixed with a first steel rope 806, the first steel rope 806 extends to the outside of the first pulley 804 and is fixedly connected to the fixed shaft 807.

[0055] In specific implementation, the existing connection device is mainly used to fix the building wall 1 and the steel structure 5, and personnel are required to determine the installation and fixing position and angle of the steel structure 5 and the building wall 1 in the early stage. During the installation process, since the connection device cannot adjust the angle, once deflection occurs, the connection device needs to be disassembled and reinstalled, and trial and error cannot be performed. Therefore, in this solution, a first hydraulic telescopic rod 7 and a positioning installation frame 4 are set, and the first hydraulic telescopic rod 7 is started to extend and retract, thereby adjusting the angle of the positioning installation frame 4, so as to achieve the effect of timely adjustment, and when the first hydraulic telescopic rod 7 is in the process of moving, the second hydraulic telescopic rod 808 is started, so that the second hydraulic telescopic rod 808 is contracted to drive the incomplete inner gear ring 809 to move, and the incomplete inner gear ring 809 is released. The ring 809 engages and locks the rotating gear 801. At this time, when the positioning installation frame 4 is upward, the rotating shaft 401 drives the rotating gear 801 to rotate, and the rotating gear 801 drives the driven gear 802 engaged on the outside to rotate, and the driven gear 802 drives the fixedly connected winding disk 803 to rotate. When the winding disk 803 rotates, it drives the first steel rope 806 wound on the outside to be wound, so that the first steel rope 806 slides on the outside of the first pulley 804, and the positioning installation frame 4 is pulled and supported. After the adjustment is completed, the second hydraulic telescopic rod 808 is started to make the incomplete inner gear ring 809 fixedly connected at one end of the second hydraulic telescopic rod 808 contact and engage with the rotating gear 801, thereby ensuring the stability of the positioning installation frame 4 and the steel structure 5 after installation and fixation.

[0059] During specific implementation, when the steel structure 5 is inserted into the positioning and installing frame 4, one end of the steel structure 5 pushes the movable plate 9 inside the positioning and installing frame 4 to slide. When the movable plate 9 slides, it drives the sliding seats 901 fixedly connected on both sides to slide on the positioning and installing frame 4. As the sliding seat 901 slides, the installation shaft 102 is pulled down under the guidance of the second pulley 104 through the fixedly connected second steel rope 103, and the installation shaft 102 drives the fixedly connected positioning plate 101 to descend. As the positioning plate 101 descends, it is continuously inserted into the installation groove 501 opened on the outside of the steel structure 5, and moves to the inside of the installation plate 502 fixed on the outside of the steel structure 5.
