Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0023] like Figure 1-5 As shown, the steel structure reinforcement unit for the renovation of ancient buildings in this embodiment includes the original wall 1 and a steel column 6 located on one side of the original wall 1. A reinforcement layer 2 is provided between the original wall 1 and the steel column 6, and the reinforcement layer 2 is attached to the right end surface of the original wall 1. The reinforcement layer 2 is made of 30 mm thick high ductility concrete. A reinforcement unit is provided on the end surface of the reinforcement layer 2 away from the original wall 1. The reinforcement unit is a steel structure as a whole, which is effectively connected with the reinforcement layer 2 to increase the overall stability. Fastening mechanisms are inserted inside the reinforcement unit to ensure the stability of the formwork during concrete pouring and to ensure the dimensional accuracy of the wall and column structures. The bottom of the steel column 6 is connected to a steel column foundation 7, which is buried in the ground to a depth of 610 mm. The top of the steel column 6 is connected to a steel beam 8.
[0024] Specifically, the reinforcement unit includes internal wall vertical keel 3, internal wall horizontal keel 4 and column bracing 5. The internal wall vertical keel 3 is connected to the surface of the reinforcement layer 2 away from the original wall 1. The other surface of the internal wall vertical keel 3 is connected with multiple internal wall horizontal keels 4 at equal intervals from top to bottom. The internal of each of the multiple internal wall horizontal keels 4 is connected with column bracing 5. The end of the column bracing 5 away from the internal wall horizontal keel 4 is connected to the steel column 6. The stability is improved by the steel keels in both the horizontal and vertical directions. At the same time, the column bracing 5 with the steel column 6 improves the overall rigidity and ensures the deformation coordination between the masonry structure and the steel structure.
[0025] Furthermore, the fastening mechanism includes tie rods 9, threaded portions 10, and nuts 12. Multiple tie rods 9 are provided, and the positions of the tie rods 9 correspond one-to-one with the positions of the transverse keel 4 of the inner wall. Threaded portions 10 are provided on the outer surfaces of both the left and right ends of the tie rods 9, and nuts 12 are connected to both the left and right ends of the tie rods 9 through the threaded portions 10. Through the tie rods 9, the reinforcement layer 2 is stably connected to the vertical keel 3 and the transverse keel 4 of the inner wall.
[0026] Furthermore, each of the two nuts 12 is fixedly connected to a connecting ring 13 on its facing surfaces. Each of the two connecting rings 13 is equipped with a self-locking component. By setting the self-locking component, the nuts 12 cannot rotate in the opposite direction after being screwed in.
[0027] Furthermore, the self-locking assembly includes a groove 14, a spring 15, and a metal spring 16. The groove 14 is opened on the inner wall of both the upper and lower ends of the connecting ring 13. The spring 15 is connected inside the two grooves 14. The metal spring 16 is connected to the end of the two springs 15 away from the groove 14. When the nut 12 is screwed in, the spring 15 is in a compressed state, so that the metal spring 16 is completely inside the groove 14.
[0028] Furthermore, waterproof gaskets 17 are connected to the opposing surfaces of the two connecting rings 13. Through the waterproof gaskets 17, the waterproof gaskets 17 are tightly attached to the wall after the nut 12 is tightened, thereby preventing moisture from seeping into the interior of the wall through the gaps and causing the tie rod 9 to rust.
[0029] Furthermore, each of the two threaded portions 10 has a wedge-shaped groove 11 on the outer surface of the pull screw 9 at its opposite ends. The shape and size of the wedge-shaped groove 11 are the same as those of the metal spring 16. The wedge-shaped groove 11 is located at the end of the threaded portion 10. When the nut 12 is tightened, the position of the metal spring 16 corresponds to the position of the wedge-shaped groove 11. Since it is no longer blocked by the surface of the pull screw 9, the metal spring 16 will pop out and insert into the interior of the wedge-shaped groove 11, thereby fixing the nut 12.
[0030] The method of use in this embodiment is as follows: the inner wall of the original wall 1 is reinforced with 30 mm thick high ductility concrete. At the same time, the tie rods 9 are used to stably connect the vertical keel 3, the horizontal keel 4 and the steel column 6 of the inner wall, thereby improving the overall rigidity and ensuring the deformation coordination between the masonry structure and the steel structure. The cross-sectional form of the vertical keel 3 and the horizontal keel 4 of the inner wall is used to improve the overall stability. When using the tie rods 9, the self-locking component can be used to easily lock the nut 12 to prevent it from rotating in the opposite direction.
[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
