[0002] The steel box girder belongs to bridge engineering. The steel box girder, also known as a steel plate box girder, is a commonly used structural form for long-span bridges. It is generally used for bridges with larger spans and is called a steel box girder because its appearance resembles a box. The steel box girder is currently the most commonly used upper structure of a bridge. However, due to the huge volume of the steel box girder and limited site space, prefabrication methods are often used for construction.

[0003] The existing patent with the publication number "CN216840216U" includes an inner steel frame and an outer steel frame. Connecting pieces are provided on the opposite sides of the inner steel frame and the outer steel frame. The left and right ends of the connecting pieces respectively penetrate through the outer steel frame and the inner steel frame. Reinforcing ribs are provided on the inner opposite sides of the inner steel frame and the outer steel frame. A first steel frame is provided on the right side of the outer steel frame. The utility model adopts the above structure. The box girder is mainly composed of an inner steel frame and an outer steel frame. Studs are arranged at both ends of the rod body. After being limited by the limiting blocks on the inner opposite sides of the outer steel frame and the inner steel frame, part of the studs penetrate through the inner steel frame and the outer steel frame and are fixed by nuts, which is convenient for installation and has high assembly efficiency. After the outer steel frame is docked with the second steel frame of the floor through the first steel frame, the angle steel at the lower end of the floor is docked with the protruding part on the right side of the inner steel frame and fixed by fixing bolts, which can facilitate the installation between the box girder and the floor.

[0004] However, there are still certain defects. Firstly, the nuts used for fixation will become loose after a long time of use, posing a potential danger. On the other hand, the floor slab and the inner and outer steel frames in the patent with the publication number "CN216840216U" are installed perpendicular to each other at 90 degrees and cannot be adjusted according to special on-site conditions for angle adjustment and installation support operations. Therefore, a prefabricated perforated steel box girder structure for an external wall is needed. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] Refer to Figures 1 - 5 An assembled perforated steel box girder structure of an external wall as shown, including a fixing plate 1, a load-bearing plate 2 rotatably connected to the inner wall of the fixing plate 1, and an anti-slip positioning mechanism provided on the inner wall of the fixing plate 1;

[0025] The anti-slip positioning mechanism includes a sliding groove 5 opened on the inner wall of the fixing plate 1. A through hole is opened on the inner bottom wall of the sliding groove 5. A lead screw 16 is rotatably connected to the inner wall of the through hole. The top end of the lead screw 16 is rotatably connected to the inner top wall of the sliding groove 5. The bottom end of the lead screw 16 is fixedly connected with a knob 17. A slider 9 is threadedly connected to the surface of the lead screw 16. The surface of the slider 9 is slidably connected to the inner wall of the sliding groove 5. A connecting block 6 is fixedly connected to the inner wall of the load-bearing plate 2. The connecting block 6 and the slider 9 are rotatably connected by the same connecting rod 8;

[0026] A threaded hole 15 is opened on the back surface of the fixing plate 1. A positioning screw 7 is threadedly connected to the inner wall of the threaded hole 15. A plurality of convex blocks 10 are fixedly connected to the inner wall of the fixing plate 1. A plastic J-shaped plate 12 and a stopper 13 are fixedly connected to the surface of the positioning screw 7. The stopper 13 abuts against one side of the plastic J-shaped plate 12;

[0027] An activity groove 4 is opened on the surface of the fixing plate 1. A connecting plate 3 is fixedly connected to the surface of the fixing plate 1.

[0028] With the above structure, by providing a through hole, spatial avoidance is provided for the installation movement of the lead screw 16. By providing a knob 17, it is convenient for the operator to rotate the knob 17 to drive the lead screw 16 to rotate and change the position of the slider 9. By providing the slider 9, when the position of the slider 9 changes, through the connection of the connecting rod 8, the connecting block 6 and the load-bearing plate 2 are driven to rotate as a whole under force, thereby controlling and changing the angle of the load-bearing plate 2 to adapt to the support in different situations. By providing a threaded hole 15, space is provided for the installation of the positioning screw 7. By providing the positioning screw 7, the positioning screw 7 is rotated to fix the fixing plate 1 on the outer wall. By providing a stopper 13, one side of the plastic J-shaped plate 12 is blocked to prevent the plastic J-shaped plate 12 from deforming to one side. By providing convex blocks 10, when the surface of the plastic J-shaped plate 12 contacts the surface of the convex blocks 10, the plastic J-shaped plate 12 is driven to deform. When the plastic J-shaped plate 12 deforms, the positioning screw 7 can be continuously rotated to better fix the fixing plate 1.

[0029] As a preferred implementation manner in this embodiment, referring to the appendix Figure 5 , the surface of the connecting plate 3 is adapted to the inner wall of the activity groove 4.

[0030] By providing that the surface of the connecting plate 3 is adapted to the inner wall of the activity groove 4, the stability after the multiple fixing plates 1 are assembled with each other is maintained. Since the inner wall of the activity groove 4 and the surface of the connecting plate 3 are part of a cylindrical shape, at the same time, the multiple fixing plates 1 can be appropriately bent and adjusted in position after being assembled.

[0031] As a preferred implementation manner in this embodiment, referring to the appendix Figure 3 , an anti-slip gasket 11 is fixedly connected to the surface of the positioning screw 7.

[0032] By setting the anti-slip gasket 11, the friction is increased to maintain the frictional fastening of the positioning screw 7.

[0033] As a preferred implementation manner in this embodiment, refer to the attached Figure 4 , an adhesive sticker 14 is fixedly connected to the back surface of the fixing plate 1.

[0034] By setting the adhesive sticker 14, the fixing plate 1 can be quickly adhered and positioned on the wall surface through the adhesive sticker 14.

[0035] As a preferred implementation manner in this embodiment, refer to the attached Figure 2 , Figure 4 , a plurality of reinforcing ribs 18 are fixedly connected to the surface of the load-bearing plate 2, and a plurality of corresponding grooves 19 are formed in the inner wall of the fixing plate 1.

[0036] By setting the reinforcing ribs 18, the support structure strength of the load-bearing plate 2 is enhanced. By setting the grooves 19, when the load-bearing plate 2 is in the storage state, space is provided for the reinforcing ribs 18.

[0037] Working principle: For an assembled perforated steel box girder structure of an external wall, during use, the operator can quickly adhere and position the fixing plate 1 on the wall surface through the adhesive sticker 14. Then, the knob 17 is rotated. The rotation of the knob 17 drives the screw rod 16 to rotate, changing the position of the slider 9. Through the connection of the connecting rod 8, the connecting block 6 and the load-bearing plate 2 are driven to rotate as a whole, thereby controlling and changing the angle of the load-bearing plate 2 to adapt to the support in different situations. Then, by using a screwdriver tool, the positioning screw 7 is driven to rotate to fix the fixing plate 1 on the outer wall. The rotation of the positioning screw 7 drives the plastic J-shaped plate 12 to rotate. The plastic J-shaped plate 12 contacts the surface of the convex block 10 and undergoes plastic deformation, without blocking or interfering with the rotating positioning screw 7. After the positioning screw 7 is fixed, if it loosens during long-term use and wants to rotate in the reverse direction, one side of the plastic J-shaped plate 12 is blocked by the surface of the convex block 10, and the stop block 13 blocks the other side of the plastic J-shaped plate 12 to prevent the plastic J-shaped plate 12 from deforming and loosening. The anti-slip gasket 11 increases the friction to maintain the frictional fastening of the positioning screw 7. With the above structure, it is possible to prevent the fixing plate 1 from loosening after being fixed on the outer wall, and the angle of the load-bearing plate 2 can be adjusted according to needs to meet the on-site installation and support requirements.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
