[0002] The modification of ancient buildings follows the following principles: 1. The principle of the protection and restoration of ancient buildings is that they must be protected in situ, the intervention should be minimized as much as possible, and regular daily maintenance should be carried out; 2. For the repair projects of memorial buildings, stone buildings, grotto murals, statues, ancient steles and stone carvings, etc., the principle of "not changing the original state" should be strictly observed; 3. The principle of "not changing the original state" refers to the original texture, style and techniques of the initial construction or the successive renovations and reconstructions.

[0003] Chinese Baroque is a brick-concrete structure, and the whole body is covered with relief decorations made of plastering. Due to the long age of these ancient buildings, most of the relief decorations of these ancient buildings have fallen off. At present, the repair method is to manually make relief decorations by workers and use bonding work for repair. This repair method has high costs, long construction periods; the repair quality depends on the technical level of workers, which will cause problems such as inconsistent styles and poor repair quality; at the same time, the repaired parts are not firm and are still easy to fall off after a few years.

Specific implementation mode

[0024] The following uses the best embodiments to describe the present invention in detail.

[0025] As Figures 1-6 shown, the precast component construction structure for repairing ancient buildings includes an ancient building wall 1 and a precast relief component 3, and also includes a steel wire mesh cylinder 8 and a reinforced mesh sleeve 6; the precast relief component 3 is manufactured in a factory according to the style of the ancient building to be repaired, and the precast relief component 3 has an installation surface that fits the surface of the ancient building wall; precast component steel bars 4 are embedded in the precast relief component 3, and at least two precast component steel bars 4 are provided for each precast relief component 3, and the number of precast component steel bars 4 is designed according to the size and shape of the precast relief component 3. The outer ends of the precast component steel bars 4 extend outside the installation surface of the precast relief component 3, and the precast component steel bars 4 are perpendicular to the installation surface; reinforcing steel bars 5 are also provided inside the precast relief component 3, and the reinforcing steel bars 5 are connected between the precast component steel bars 4. For precast relief components 3 with larger sizes and weights, setting the reinforcing steel bars 5 can play a role in reinforcement.

[0026] On the wall surface of the ancient building wall 1 at the installation position of the relief, implanted bar holes 7 are opened, and the positions and numbers of the implanted bar holes 7 correspond to the positions and numbers of the precast component steel bars 4. The steel wire mesh cylinder 8 is arranged in the implanted bar holes 7, and the surface is attached to the inner surface of the implanted bar holes 7, and the implanted bar holes 7 are filled with concrete slurry; a reinforced mesh sleeve 6 is sleeved outside each precast component steel bar 4, and the surface of the reinforced mesh sleeve 6 has V-shaped cutting holes 61, and the triangular pieces 62 formed by cutting outside the V-shaped cutting holes 61 are warped outwards; the precast component steel bars 4 together with the reinforced mesh sleeve 6 are inserted into the implanted bar holes 7, the sharp corners of the V-shaped cutting holes 61 face the outer ports of the implanted bar holes 7, and the sharp corners of the triangular pieces 62 are stuck in the mesh holes of the steel wire mesh cylinder 8. When inserting the reinforced mesh sleeve 6 into the implanted bar holes 7, the triangular pieces 62 can be pressed to smoothly enter the implanted bar holes 7. After stopping pulling, the triangular pieces 62 of the steel reinforced mesh sleeve 6 warp outwards under the elastic action and can be stuck into the mesh holes of the steel wire mesh cylinder 8. After the concrete in the holes dries, the connection between the precast component steel bars and the implanted bar holes 7 is more firm.

[0027] At the position where the relief is to be installed on the ancient building wall 1, there is also a cylindrical hole 2. The implanting bar hole 7 is arranged at the bottom end face of the cylindrical hole. On the installation surface of the precast relief component 3, there is a cylinder 31. The cylinder 31 and the precast relief component 3 are of an integral structure. The cylinder is embedded in the cylindrical hole 2 of the ancient building wall 1. Then, the precast component steel bar 4 of the precast relief component 3 is installed in the implanting bar hole 7. The structure with the cooperation of the cylinder 31 and the cylindrical hole 2 is used to bear the weight of the precast relief component, preventing the phenomenon that the precast component steel bar is bent due to the excessive weight and size of the precast relief component.

[0028] Construction process:

[0029] Demolish the original damaged relief on the ancient building wall;

[0030] Manufacture the precast relief component in the factory;

[0031] Measure the corresponding points of the precast component steel bar position on the wall surface at the relief installation position of the ancient building wall and draw lines;

[0032] Drill the implanting bar holes at the line-drawing positions on the ancient building wall;

[0033] A steel wire mesh cylinder 8 is arranged in the implanting bar hole 7, and the precast component steel bar is installed with a reinforcement mesh sleeve;

[0034] Pour the concrete slurry into the hole and insert the precast component steel bar;

[0035] After the concrete slurry in the hole dries, the installation of the precast relief component is completed.
