Description

Technical Field

[0001] The utility model relates to the technical field of historical building protection, in particular to a building exterior wall. Background Art

[0002] In the field of historical building protection, when brick-and-wood structure historical buildings are facing demolition or relocation, valuable exterior wall decoration parts need to be dismantled and restored.

[0003] Traditional dismantling methods usually involve breaking the exterior walls into individual bricks or multiple small components. This is not only labor-intensive, but also, due to limitations in preservation conditions, bricks and small components may be deformed and damaged during dismantling, preservation, and transportation, making it impossible to fully restore them or losing their original appearance and historical value after restoration. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a building exterior wall that solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: a building exterior wall, installed on an original wall, comprising: a decorative wall surface for decoration, a reserved wall formed by demolishing the original wall, a steel frame implanted on the back of the reserved wall, embedded hooks arranged on the steel frame, a casting template surrounding the steel frame and the reserved wall, a backing wall formed by the casting template, and a wooden beam pad and a sling for transportation, wherein the decorative wall surface is fixedly installed on the front side of the reserved wall.

[0006] Preferably, the casting formwork includes side formwork and bottom formwork, the side formworks are respectively arranged around the reserved wall and the steel frame, and the bottom formwork is arranged at the bottom of the reserved wall and the steel frame, and is in close contact and fixed with the reserved wall and the steel frame by bolts, thereby forming a cavity that wraps the reserved wall and the steel frame. Then, concrete is poured into the cavity, and after the concrete solidifies, a backing wall connecting the reserved wall and the steel frame is formed.

[0007] Preferably, after the backing wall is formed, the end of the embedded hook passes through the backing wall and is connected to the sling, and the end of the sling away from the embedded hook is fixedly connected to the crane.

[0008] Preferably, the reserved wall further comprises reserved bricks arranged in a tooth-shaped pattern on the back side thereof, and the reserved bricks are located inside the cavity formed by the casting formwork.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] When the original wall of the building's exterior wall was demolished, the appearance integrity and authenticity of the decorative wall were retained to the greatest extent by retaining the reserved wall on the back of the complete decorative wall. The bricks on the reserved wall were arranged in a tooth-shaped joint, and a steel frame and embedded hooks were implanted on the reserved wall. Finally, the formwork was supported and concrete was poured to form the backing wall. The tooth-shaped joint design allows the reserved wall and the backing wall to form a whole, enhancing the overall stability and preventing cracks and deformation in the wall, so as to facilitate the subsequent stable connection between the sling and the embedded hook, and avoid damage to the decorative wall during lifting, transportation and storage.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-3 The sling 8 of the present invention is fixed on the front surface of the prefabricated wall 3, and the sling 8 of the present invention is fixed on the front surface of the prefabricated wall 3.

[0017] The casting formwork includes side formwork and bottom formwork. The side formwork is respectively arranged around the reserved wall 3 and the steel frame 4. The bottom formwork is arranged at the bottom of the reserved wall 3 and the steel frame 4, and is in close contact and fixed with the reserved wall 3 and the steel frame 4 by bolts, thereby forming a cavity that wraps the reserved wall 3 and the steel frame 4. Then, concrete is poured into the cavity. After the concrete solidifies, a backing wall 5 connecting the reserved wall 3 and the steel frame 4 is formed. The reserved wall 3 also includes reserved bricks arranged in a tooth joint on the back side thereof, and the reserved bricks are located inside the cavity formed by the casting formwork, and the reserved bricks arranged in a tooth joint can increase the strength of the connection between the reserved wall 3 and the backing wall 5 to reduce the possibility of damage during transportation.

[0018] Working principle: first, all components are surveyed and numbered in detail at the same time, and the scope of the decorative wall 1 that needs to be retained is clarified to ensure accuracy during disassembly and restoration. Then, the selected original wall 2 is disassembled, and a layer of bricks on the back of the decorative wall 1 is retained, and a staggered brick arrangement is reserved to form a reserved wall 3. A steel frame 4 is implanted in the reserved wall 3. Finally, the reserved wall 3 and the steel frame 4 are wrapped with formwork, and concrete is poured to form a backing wall 5 that is integrated with the reserved wall 3. After pouring, the formwork is removed, and embedded hooks 6 are reserved on the backing wall 5. At this time, the decorative wall 1, the reserved wall 3 and the backing wall 5 can form a whole, and then the slings 8 are used to connect the embedded hooks 6, and the wooden beam pads 7 are used to protect the bottom of the entire wall to achieve hoisting, transportation and storage. The whole is installed when it is restored. The overall disassembly and hoisting method reduces the workload and reduces the risk of damage to the decorative wall 1 during storage and transportation.

[0019] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
