Description
Technical Field
[0001] This utility model relates to the field of protection technology for the remaining exterior walls of historical buildings, and in particular to a protection structure for the remaining exterior walls of historical buildings. Background Technology
[0002] The remaining exterior walls of historical buildings typically refer to the parts of the external wall structure that have survived after historical buildings have undergone natural erosion, war, demolition, renovation, or disasters. These remaining exterior walls may carry the historical memory, cultural value, or artistic features of the building, and are important material evidence for the study of architectural history, urban development, or cultural heritage.
[0003] Against the backdrop of continuous geological environmental evolution and intensified soil erosion, the foundations of historical building walls exhibit a gradual uplift. Under long-term wind loads, the walls often show a tendency to tilt and become unstable. However, traditional supporting steel frames mostly use fixed support surfaces perpendicular to the ground, which limits the effective contact area between the support and the tilted wall. Furthermore, during continuous stress, the shear stress generated at the support points may cause mechanical damage to the wall structure, creating a risk of secondary failure. Utility Model Content
[0004] The purpose of this invention is to solve the problems existing in the prior art.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a protective structure for the remaining exterior walls of a historical building, comprising the remaining exterior walls and a foundation; including:
[0006] A casting plug is fixedly installed in the direction of the collapse of the remaining outer wall, and a support arm is fixedly connected to the top of the casting plug;
[0007] A rotating sleeve is fixedly connected to the end of the support arm, and a rotating shaft is fixedly connected inside the rotating sleeve;
[0008] Support plate, which is rotatably connected to the end of the rotating sleeve;
[0009] The locking mechanism is fixedly connected to both ends of the support plate and is connected to the rotating shaft to recast and fix the cast bolts to the side of the foundation. The support plate supports the wall through the support arm. The angle of the support plate can be adjusted by the locking mechanism so that the angle of the support plate is the same as the inclination angle of the foundation. This allows the support surface of the support plate to fully contact the remaining outer wall, thus achieving the function of stabilizing the foundation. The surface support can prevent shear stress from causing mechanical damage to the wall structure and prevent the risk of secondary damage.
[0010] In a preferred embodiment, the support arm is arc-shaped, and multiple sets of staggered reinforcing ribs are fixedly connected within the arc. By setting the reinforcing ribs, the integrity of each point of the support arm is improved, and the support strength and stability of the reinforcing ribs are enhanced.
[0011] In a preferred embodiment, the locking mechanism includes a fixed ring fixedly connected to the end of the support plate, an adjusting ring rotatably connected to the end of the fixed ring, and three evenly distributed fixed clamping pieces slidably connected to the fixed ring. Each fixed clamping piece has a sliding pin fixedly connected to its end. The adjusting ring has a guide groove corresponding to each sliding pin, and the sliding pin is slidably connected inside the corresponding guide groove. By rotating the adjusting ring and engaging the guide groove, the sliding pin is pressed and driven, which can simultaneously drive multiple fixed clamping pieces to move in opposite directions, so that the three fixed clamping pieces are firmly pressed and fixed on the rotating shaft, thereby realizing the function of fixing the angle of the support plate.
[0012] In a preferred embodiment, an adjustment box is fixedly connected to the side wall of the fixed ring, a worm gear is rotatably connected inside the adjustment box, and a worm rack is fixedly embedded in the side wall of the adjustment ring. The worm rack and the worm gear are meshed and connected for transmission. The worm gear and the worm rack have a self-locking property. The adjustment ring is driven by the worm gear, which is more stable and easier to operate.
[0013] In a preferred embodiment, a handle is fixedly connected to the end of the worm gear. The handle has evenly distributed rectangular grooves on its outer periphery. The handle facilitates the rotation of the worm gear, and the rectangular grooves on the outer periphery of the handle can improve the contact friction of the handle, making it easier to drive the handle to rotate.
[0014] In a preferred embodiment, the end face of the fixing clamping piece is arc-shaped, and the fixing ring has three evenly distributed sliding grooves. The vertical end of the fixing clamping piece is slidably connected to the corresponding sliding groove. By setting the sliding grooves, the sliding of the fixing clamping piece is limited, making the sliding of the fixing clamping piece more stable.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] This invention involves recasting and fixing the cast-in-place bolt to the side of the foundation to form a stable support end seat. The support arm, in conjunction with the support plate, supports the wall. The angle of the support plate can be adjusted by a locking mechanism, so that the angle of the support plate is the same as the tilt angle of the remaining external wall. This allows the support surface of the support plate to fully contact the remaining external wall, achieving the function of providing stable support for the remaining external wall. The surface support can prevent shear stress from causing mechanical damage to the wall structure and prevent the risk of secondary damage. Attached Figure Description

Detailed Implementation
[0023] 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.
[0024] Please see Figure 1-4 This utility model provides a technical solution: a protective structure for the remaining exterior wall of a historical building, comprising the remaining exterior wall 1 and a foundation 2; including:
[0025] A casting bolt 3 is fixedly installed in the direction of the collapse of the remaining outer wall 1, and a support arm 4 is fixedly connected to the top of the casting bolt 3;
[0026] Rotating sleeve 7 is fixedly connected to the end of support arm 4, and rotating shaft 8 is fixedly connected inside rotating sleeve 7;
[0027] Support plate 6 is rotatably connected to the end of rotating sleeve 7;
[0028] Locking mechanism 9 is fixedly connected to both ends of support plate 6 and is connected to rotating shaft 8 for transmission.
[0029] The cast anchor 3 is recast and fixed to the side of the foundation 2 to form a stable support end seat. The support arm 4 and the support plate 6 are used to support the wall. The angle of the support plate 6 can be adjusted by the locking mechanism 9 so that the angle of the support plate 6 is the same as the tilt angle of the residual outer wall 1. This allows the support surface of the support plate 6 to fully contact the residual outer wall 1, thus achieving the function of providing stable support for the residual outer wall 1. The surface support can prevent shear stress from causing mechanical damage to the wall structure and prevent the risk of secondary damage.
[0030] like Figure 1-4 As shown, the support arm 4 is arc-shaped, and multiple sets of staggered reinforcing ribs 5 are fixedly connected inside the arc. By setting the reinforcing ribs 5, the integrity of each point of the support arm 4 is improved, and the support strength and stability of the reinforcing ribs 5 are enhanced.
[0031] like Figure 1-4 As shown, the locking mechanism 9 includes a fixed ring 901 fixedly connected to the end of the support plate 6. An adjusting ring 902 is rotatably connected to the end of the fixed ring 901. Three evenly distributed fixed clamping pieces 905 are slidably connected to the fixed ring 901. Each fixed clamping piece 905 has a sliding pin 906 fixedly connected to its end. The adjusting ring 902 is provided with a guide groove 910 corresponding to the sliding pin 906. The sliding pin 906 is slidably connected inside the corresponding guide groove 910. By rotating the adjusting ring 902 in conjunction with the guide groove 910, the sliding pin 906 is squeezed and driven, which can simultaneously drive multiple fixed clamping pieces 905 to move in opposite directions, so that the three fixed clamping pieces 905 are firmly squeezed and fixed on the rotating shaft 8, thereby realizing the function of fixing the angle of the support plate 6.
[0032] like Figure 1-4 As shown, an adjusting box 903 is fixedly connected to the side wall of the fixed ring 901. A worm gear 908 is rotatably connected inside the adjusting box 903. A worm rack 909 is fixedly embedded in the side wall of the adjusting ring 902. The worm rack 909 and the worm gear 908 mesh and drive each other. The worm gear 908 and the worm rack 909 have a self-locking property. The adjusting ring 902 is driven by the worm gear 908, which makes the operation more stable and convenient.
[0033] like Figure 1-4 As shown, a handle 904 is fixedly connected to the end of the worm 908. The handle 904 has evenly distributed rectangular grooves on its outer periphery. The handle 904 facilitates the rotation of the worm 908. The rectangular grooves on the outer periphery of the handle 904 can improve the contact friction of the handle 904, making it easier to drive the handle 904 to rotate.
[0034] like Figure 1-4As shown, the end face of the fixed clamping piece 905 is arc-shaped, and the fixed ring 901 has three evenly distributed sliding grooves 907. The vertical end of the fixed clamping piece 905 is slidably connected to the corresponding sliding groove 907. By setting the sliding groove 907, the sliding of the fixed clamping piece 905 is limited, making the sliding of the fixed clamping piece 905 more stable.
[0035] Working principle: When adjusting the angle of the support plate 6 through the locking mechanism 9, the rotating handle 904 drives the worm gear 908 to rotate, which, together with the worm rack 909, drives the rotation of the adjusting ring 902. The rotation of the adjusting ring 902, together with the guide groove 910, compresses the sliding pin 906, which can simultaneously drive multiple fixed clamping pieces 905 to move in opposite directions, so that the three fixed clamping pieces 905 are away from the rotating shaft 8. At this time, there is no contact restriction between the support plate 6 and the rotating shaft 8. After adjusting the rotation angle, rotating the handle 904 in the opposite direction will fix the support plate 6 in place on the rotating shaft 8, thus realizing the function of adjusting the angle of the support plate 6.
