The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0023] Specific implementation method 1: Combination Figures 1 to 14 The present embodiment is described. The clamping repair structure in the present embodiment is used to repair and reinforce a local part of an old wall 10 or the inner and outer wall surfaces of the entire wall. The clamping repair structure includes an outer patch 30, an inner patch 40 and a plurality of steel pipes 12. The outer patch 30 and the inner patch 40 are both U-shaped patches. The middle portion of the outer patch 30 is used to enclose and reinforce the wall surface on the outdoor side of the old wall 10. The two ends of the outer patch 30 are first fixed ends, which are used to cooperate and fix the middle position of the outer patch 30. The outer patch 30 is arranged on the outdoor side of the old wall 10, and the inner patch 40 is arranged on the indoor side of the old wall 10.

[0024] The middle part of the inner patch 40 is used to enclose and reinforce the wall surface on the indoor side of the old wall 10 , and the two ends of the inner patch 40 are second fixed ends, which are used to cooperate and fix the middle position of the inner patch 40 .

[0025] The outer patch 30 includes an outer mesh 11, a first positioning plug-in block 22, a second positioning plug-in block 25, a first plug-in block 4-1 and a second plug-in block 4-2. The outer mesh 11 is vertically arranged, and the inner side wall of the outer mesh 11 is matched with the outer close-fitting wall of the old wall 10. The two ends of the outer mesh 11 are respectively connected with the first plug-in block 4-1 and the second plug-in block 4-2 in an integral manner.

The outer mesh 11 is connected to the first positioning plug-in block 22 and the second positioning plug-in block 25. The two positioning blocks 25 are detachably connected to the outdoor side of the old wall 10; the inner patch 40 includes an inner mesh 1, a first connecting piece 2 and a second connecting piece 5, the inner mesh 1 is vertically arranged, and the first connecting piece 2 and the second connecting piece 5 are respectively arranged at both ends of the inner mesh 1, and the inner mesh 1 is detachably connected to the indoor side of the old wall 10 through the first connecting piece 2 and the second connecting piece 5, and the outer side wall of the inner mesh 1 is adapted to fit the inner close-fitting wall of the old wall 10, and a plurality of steel pipes 12 are passed through the outer mesh 11, the old wall 10 and the inner mesh 1.

[0026] When the old wall 10 repaired by the utility model is a non-load-bearing wall, the first positioning block 22 and the second positioning block 25 are respectively arranged on other adjacent walls on both sides of the old wall 10 to be repaired. The other adjacent walls on both sides of the old wall 10 are load-bearing walls or non-load-bearing walls. The positioning of the outer mesh sheet 11 is achieved by detachably connecting the first plug piece 4-1 with the first positioning block 22 and detachably connecting the second plug piece 4-2 with the second positioning block 25.

[0027] When the old wall 10 repaired by the utility model is a load-bearing wall, the first positioning block 22 and the second positioning block 25 are respectively arranged on other adjacent walls on both sides of the old wall 10 to be repaired. The other adjacent walls on both sides of the old wall 10 are load-bearing walls or non-load-bearing walls. The positioning of the outer mesh sheet 11 is achieved by detachably connecting the first plug piece 4-1 with the first positioning block 22 and detachably connecting the second plug piece 4-2 with the second positioning block 25.

[0028] The steel pipe 12 is filled with concrete slurry or cement slurry.

[0029] Specific implementation method 2: This implementation method is a further limitation of the specific implementation method 1. Figure 3As shown, the first positioning block 22 is provided with an external fixing plate 50, and the second positioning block 25 is provided with another external fixing plate 50. The external fixing plate 50 is a straight plate body or a Z-shaped plate body, which is used to form an enclosure groove body with other walls adjacent to the two sides of the old wall 10 to be repaired, and is used to accommodate the first positioning block 22. A plurality of first connecting members 60 are inserted through the external fixing plate 50, the first positioning block 22 and other walls adjacent to one side of the old wall 10 to be repaired to realize the clamping and positioning process of the first positioning block 22, thereby facilitating the rapid positioning of the outer mesh 11. Similarly, the connection method between the second positioning block 25 and another external fixing plate 50 on the other walls adjacent to one side of the old wall 10 to be repaired is the same as the connection method between the first positioning block 22 and an external fixing plate 50.

[0030] Similarly, the first connecting piece 2 and the second connecting piece 5 are each provided with an inner fixing plate 80 , and the structure and connection method of the inner fixing plate 80 are the same as those of the outer fixing plate 50 .

After the steel pipe 12 is penetrated, the mortar layer is applied to achieve the flatness of the facade. Alternatively, the area where the outer mesh 11 with the steel pipe 12 is located is cast through the existing external support formwork, and after casting, the outer mesh 11, the inner mesh 1 and multiple steel pipes 12 form a through-type double-sided reinforcement process that matches the old wall 10.

[0037] When the clamping type repair structure is an outer wide mesh and the inner mesh 1 is an inner wide mesh, it is used to repair large-area damaged areas of the old wall 10 .

[0038] Furthermore, multiple outer narrow strip meshes can also be used in combination to repair large damaged areas on the outside of the old wall 10. When multiple outer narrow strip meshes are used in combination, two adjacent outer narrow strip meshes are set closely together. Similarly, multiple inner narrow strip meshes can also be used in combination to repair large damaged areas on the inside of the old wall 10. When multiple inner narrow strip meshes are used in combination, two adjacent inner narrow strip meshes are set closely together.

[0039] Specific embodiment six: This embodiment is a further limitation of specific embodiments one, two, three, four or five. The outer mesh 11 is processed with a first long hole 11-1 along its length direction to match the steel pipe 12. The length direction of the first long hole 11-1 is in the same direction as the length direction of the outer mesh 11. The inner mesh 1 is processed with a second long hole 1-1 along its length direction to match the steel pipe 12.

When multiple outer mesh sheets 11 are stacked from bottom to top, the two first semicircular groove bodies 13-1 between the upper and lower sides of two adjacent outer mesh sheets 11 enclose another The first long hole 11-1 is used to cooperate with the steel pipe 12 to realize the threading process at the side edge of the outer mesh 11. Similarly, the upper and lower sides of the inner mesh 1 are respectively processed with second semicircular grooves 13-2 that cooperate with the steel pipe 12. When multiple inner meshes 1 are stacked from bottom to top, the two second semicircular grooves 13-2 between the upper and lower sides of two adjacent inner meshes 1 are enclosed to form another second long hole 1-1, which is used to cooperate with the steel pipe 12 to realize the threading process at the side edge of the inner mesh 1.

Fig.13 As shown, another structural form of the slot 22-2 is a half-slot shape. The slot 22-2 of this structural form is conducive to the insertion position of the first plug-in piece 4-1 or the second plug-in piece 4-2, and can also facilitate the first plug-in piece 4-1 or the second plug-in piece 4-2 to be attached to the outdoor side of the old wall 10, thereby increasing the contact area between the external patch 30 and the old wall 10.

[0043] Further, combined with Figure 1 and Fig.11 As shown, the external patch 30 also corresponds to the first or second form of the matching slot 22-2 to adapt to different plug-in locations.
