[0025] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] The cross beam reinforcement grouting steel trough structure of this embodiment is used to repair and reinforce cross beams with cracking, fracture and other conditions.

[0027] As Figures 1 to 3 shown, the cross beam reinforcement grouting steel trough structure includes an original cross beam 10, two side wall plates 20 and a bottom plate.

[0028] The original cross beam 10 is a house cross beam structure. In this house structure, a panel 11 is provided above the original cross beam 10. The original cross beam 10 is connected to the panel 11. The original cross beam 10 has a cracking opening 12.

[0029] The two side wall plates 20 are respectively arranged on both sides of the original cross beam 10. A number of screw rods 21 are connected to the top end of each side wall plate 20. The number of screw rods 21 is evenly distributed at the top end of the side wall plate 20 at a certain interval. In addition, one or more grouting holes 22 are provided on one of the side wall plates 20 or both side wall plates 20.

[0030] When the grouting holes 22 are externally connected with grouting pipes, it is possible to pour slurry between the two side wall plates 20. In this embodiment, only one grouting hole 22 is respectively provided at the diagonals on one of the side wall plates 20.

[0031] A connecting hole is provided at a position on the panel 11 corresponding to the screw 21, and the connecting hole penetrates through the entire panel 11. The screw 21 on the side wall plate 20 passes through the connecting hole on the panel 11, and then a welding steel plate 23 is provided at the top end of the screw 21 passing through the connecting hole. The screw 21 is fixed to the top end of the panel 11 by using the welding steel plate 23.

[0032] The bottom plate includes an upper bottom plate 31, a lower bottom plate 32, and a rib plate 33. The two sides of the lower bottom plate 32 are respectively in contact connection with the bottom edges of the left and right side wall plates 20. There is a certain interval between the upper bottom plate 31 and the lower bottom plate 32, and it is arranged above the lower bottom plate 32.

[0033] The rib plate 33 is arranged between the upper bottom plate 31 and the lower bottom plate 32. The upper end of the rib plate 33 is connected to the center of the bottom of the upper bottom plate 31, and the lower end is connected to the center of the top of the lower bottom plate 32, forming two spaces between the upper bottom plate 31 and the lower bottom plate 32, providing bending strength and a small amount of shear strength for the bottom plate 20.

[0034] The two side wall plates 20 and the bottom plate are welded to form a U-shaped steel groove 40. The U-shaped steel groove 40 wraps around the cracking opening on the original cross beam 10. In addition, the bottom edge of the U-shaped steel groove 40 is the upper bottom plate 31 of the bottom plate.

[0035] Then, grouting is carried out into the U-shaped steel groove 40 through the grouting hole 22 on the side wall plate 20, and the grouting material 50 can be epoxy glue or cement-based high-strength material. After grouting, the U-shaped steel groove 40 conducts bending moment and shear force with the original cross beam, providing shear strength. And the grouting material has better crack resistance than concrete, reducing the risk of crack regeneration after reinforcement and repair.

[0036] In addition, after the grouting of the U-shaped steel groove 40 is completed, anti-corrosion treatments such as painting and rust removal can be carried out on its outer surface to prevent its outer surface from rusting.

[0037] In the cross beam reinforcement grouting steel groove structure according to the above embodiment, it includes an original cross beam, side wall plates, and a bottom plate. There is a cracking opening on the original cross beam, the side wall plates are arranged on both sides of the original cross beam, the bottom plate is arranged at the bottom of the original cross beam, and the bottom plate is connected to the side wall plates. Among them, the side wall plates and the bottom plate form a U-shaped steel groove, the steel groove wraps around the cracking opening on the original cross beam, and grouting is poured into the U-shaped steel groove. Based on this cross beam reinforcement grouting steel groove structure, the cracking opening is wrapped by the steel groove structure, and then grouting is poured into the steel groove. After reinforcement, the bearing capacity of the cross beam can be greatly improved, preventing it from cracking again. And this reinforcement grouting steel groove structure occupies a small space and has a beautiful appearance. In addition, the regular and flat surface of the steel groove is convenient for anti-corrosion treatments such as painting and rust removal, and it is not easy to rust after spraying paint on the surface of the steel groove, solving the problems of insufficient bearing capacity, insufficient durability, too large volume, and rust in the existing cross beam reinforcement methods.

[0038] In addition, the bottom plate includes an upper bottom plate and a lower bottom plate. Both sides of the lower bottom plate are respectively connected to the bottom edges of the side wall plates. The upper bottom plate is arranged above the lower bottom plate, and rib plates are also arranged between the upper bottom plate and the lower bottom plate. Connecting the upper bottom plate and the lower bottom plate through the rib plates can enhance the bending strength of the bottom plate, and provide shear strength, increasing the strength of the bottom plate.

[0039] In addition, a number of screws are also arranged on the side wall plates. The screws pass through the panel on the cross beam, then pass through the connection holes on the panel, and are fixed above the panel by welding steel plates, strengthening the connection strength between the side wall plates and the panel. Moreover, the number of screws is evenly distributed at the top of the side wall plates, which can evenly distribute the connection force on the side wall plates and prevent the side wall plates from tilting.

[0040] Not only that, but grouting holes are provided on the side wall plates. An external grouting pipeline is connected through the grouting holes, which is convenient for grouting into the steel trough.
