[0004] In summary, existing technologies for renovating the walls of old buildings suffer from technical problems such as insufficient support due to structural issues, making it impossible to make reasonable use of existing space. Utility Model Content

[0005] This utility model aims to solve the technical problem that existing technologies for renovating old building walls have insufficient support due to structural issues, making it impossible to make reasonable use of existing space. Therefore, it provides a wall support structure for renovating old buildings, which includes steel beams, diagonal braces, support piers, hardening layers, sprayed mesh layers, and limiting steel structures.

[0006] The limiting steel structure includes angle steel and connecting steel. The angle steel is vertically wrapped around the corner of the wall, and adjacent angle steels are connected by horizontally arranged connecting steel.

[0007] The steel beam is fixedly installed on the outside of the limiting steel structure in a horizontal direction. The lower part of the steel beam is covered with a sprayed mesh layer along the wall surface. The bottom of the sprayed mesh layer is fixedly connected to the hardened layer laid in a horizontal direction. The support pier is set on the upper surface of the hardened layer.

[0008] As another improvement of this utility model, it also includes a connecting anchor rod, one end of which extends into the wall and passes through the sprayed mesh layer, and the other end of which extends into the hardened layer.

[0009] As another improvement of this utility model, the connecting anchor rod is a hollow anchor rod.

[0010] As another improvement of this utility model, it also includes a connecting bar, one end of which is fixedly connected to the connecting steel, and the other end of which is fixedly connected to the end of the connecting anchor rod in the hardened layer.

[0011] As another improvement of this utility model, one end of the connecting bar is fixedly connected to the connecting steel by welding, and the other end of the connecting bar is fixedly connected to the end of the connecting anchor rod in the hardened layer by welding.

[0012] As another improvement of this utility model, the sprayed mesh layer includes a wire mesh and a concrete layer, with the top of the wire mesh hanging on the outside of the connecting steel, and the concrete layer covering the outside of the wire mesh.

[0013] As another improvement of this utility model, the longitudinal section shape of the beam steel is a right trapezoid.

[0014] As another improvement of this utility model, the support pier is a reinforced concrete structure, and the concrete inside the support pier is of type C40.

[0015] As another improvement of this utility model, the hardening layer is a concrete structure, the concrete type of the hardening layer is C40, and the support pier is made into one piece with the hardening layer.

[0016] As another improvement of this utility model, the beam steel is fixedly connected to the limiting steel structure by welding, and the two ends of the inclined support can be detachably abutted against the support surface of the support pier and the side of the beam steel.

[0017] The beneficial effects of this utility model are:

[0018] The combination of limiting steel structure, diagonal bracing, and hardening layer enhances the support for the old building walls. At the same time, the limiting steel structure and diagonal bracing can be removed, improving construction efficiency and saving construction costs. Furthermore, the wall can be fixed by limiting it from only one side, making reasonable use of the limited existing space. After construction is completed, the hardening layer and support piers only need to remain in place and be mixed with the pre-constructed road surface without the need for additional removal. Moreover, the materials of the hardening layer and support piers are concrete themselves, saving construction costs and improving construction efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Specific implementation method one: Combining Figures 1 to 3 This embodiment describes a wall support structure for the renovation of old buildings, which includes a steel beam 1, a diagonal brace 2, a support pier 3, a hardened layer 4, a sprayed mesh layer 5, and a limiting steel structure.

[0024] The limiting steel structure includes angle steel 6 and connecting steel 7. The angle steel 6 is vertically wrapped around the corner of the wall, and adjacent angle steel 6 are connected by horizontally arranged connecting steel 7.

[0025] The beam 1 is fixedly installed on the outside of the limiting steel structure in the horizontal direction. The lower part of the beam 1 is covered with a mesh spray layer 5 along the wall surface. The bottom of the mesh spray layer 5 is fixedly connected to the hardened layer 4 laid in the horizontal direction. The support pier 3 is set on the upper surface of the hardened layer 4. One end of the inclined support 2 abuts against the support surface of the support pier 3, and the other end of the inclined support 2 abuts against the side of the beam 1.

[0026] The combination of limiting steel structures, diagonal supports, and hardening layers enhances the support for the walls of old buildings. The limiting steel structures and diagonal supports can be removed, improving construction efficiency and saving costs. Furthermore, wall fixation can be completed from only one side, making efficient use of limited existing space. After construction, the hardening layer and support piers simply remain in place and can be integrated with the pre-constructed road surface. During road construction, the top surface elevation must be greater than or equal to the top surface elevation of the support piers, eliminating the need for additional removal. Since the hardening layer and support piers are themselves made of concrete, construction costs are saved and construction efficiency is improved.

[0027] Specific Implementation Method Two: Combining Figures 1 to 3 This embodiment differs from Specific Embodiment 1 in that it also includes a connecting anchor rod 8. One end of the connecting anchor rod 8 extends into the wall and passes through the sprayed mesh layer 5, while the other end extends into the hardened layer 4. The connecting anchor rod connects the wall, the sprayed mesh layer, and the hardened layer into a unified structure, increasing the stability of the old wall. Other components and connection methods are the same as in Specific Embodiment 1.

Other components and connection methods are the same as in specific embodiment one or two.

[0029] Specific implementation method four: Combination Figures 1 to 3 This embodiment differs from specific embodiment one in that it also includes a connecting rib. One end of the connecting rib is fixedly connected to the connecting steel 7, and the other end is fixedly connected to the end of the connecting anchor rod 8 within the hardened layer 4. The connecting rib is used to improve the connection stability between the limiting steel structure and the hardened layer, thereby improving the overall structural stability. Other components and connection methods are the same as in any one of specific embodiments one to three.

[0030] Specific Implementation Method Five: Combining Figures 1 to 3 This embodiment differs from specific embodiment one in that one end of the connecting rib is fixedly connected to the connecting steel 7 by welding, and the other end of the connecting rib is fixedly connected to the end of the connecting anchor rod 8 within the hardened layer 4 by welding. The welding method is simple, reliable, and convenient to construct. Other components and connection methods are the same as any one of specific embodiments one to four.

[0031] Specific Implementation Method Six: Combination Figures 1 to 3 This embodiment differs from specific embodiment one in that the sprayed mesh layer 5 includes a wire mesh and a concrete layer. The top of the wire mesh is hung on the outside of the connecting steel 7, and the concrete layer covers the outside of the wire mesh. The sprayed mesh structure is simple and easy to implement, while also reinforcing the old wall. Other components and connection methods are the same as any one of specific embodiments one to five.

[0032] Specific implementation method seven: Combination Figures 1 to 3 This embodiment differs from specific embodiment one in that the longitudinal section of beam 1 is a right trapezoid.

The supporting pier 3 is integrally formed with the hardened layer 4. This design, using the same concrete type for the hardened layer 4 as the supporting pier, facilitates construction and ensures high structural stability. Other components and connection methods are the same as any one of specific embodiments one through eight.

[0035] Specific Implementation Method Ten: Combining Figures 1 to 3 This embodiment differs from specific embodiment one in that the beam 1 is fixedly connected to the limiting steel structure by welding, and the two ends of the diagonal support 2 are detachable and abut against the supporting surface of the support pier 3 and the side of the beam 1. The limiting steel structure and the diagonal support can be removed, improving construction efficiency and saving construction costs. Other components and connection methods are the same as any one of specific embodiments one to nine.

[0037] The combination of limiting steel structures, diagonal supports, and hardening layers enhances the support for the walls of old buildings. The limiting steel structures and diagonal supports can be removed, improving construction efficiency and saving costs. Furthermore, wall fixation can be completed from only one side, making efficient use of limited existing space. After construction, the hardening layer and support piers simply remain in place and can be integrated with the pre-constructed road surface.
