Description

Technical Field

[0001] This application relates to the field of wall reinforcement technology, and more specifically, to a reinforcement device for improving the overall integrity of hollow walls in ancient buildings. Background Technology

[0002] Hollow walls are constructed by side-laying or alternating side-laying with bricks. They are typically built with standard bricks (240mm × 115mm × 53mm) and are classified according to the direction of bricklaying. Compared to ordinary solid walls of the same thickness, hollow walls save on bricks, mortar, and labor. Furthermore, the air gaps within the wall improve thermal insulation. However, due to their internal hollow structure, hollow walls have poor seismic performance and insufficient overall rigidity, requiring reinforcement after long-term use. Reinforcement involves drilling numerous holes in the existing building's brickwork and floor slabs to install tie rods and reinforcing bars. While reinforcing the overall connection, this process also reduces the structural stability and load-bearing capacity of the original building's walls and floors.

[0003] Therefore, a reinforcement device is needed to improve the overall integrity of the hollow walls of ancient buildings in order to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a reinforcement device for improving the overall integrity of hollow walls in ancient buildings, comprising: an original wall, a floor layer, and a roof slab layer. The original wall includes bracket bricks, header bricks, tenon bricks, and grouting. The interior surface of the original wall is provided with a concrete layer and a decorative surface from the outside to the inside. An opening groove is provided between the floor layer and the original wall. The opening groove is filled with base concrete and a pre-embedded bottom channel steel. A top channel steel is installed at the bottom of the roof slab layer. A steel reinforcement layer is connected between the top channel steel and the opening groove. The steel reinforcement layer is pre-embedded in the concrete layer, and the upper and lower parts of the steel reinforcement layer are respectively inserted into the top channel steel and the bottom channel steel.

[0006] Furthermore, the top channel steel is attached to the inner end face of the original wall and the lower end face of the top slab layer. An expansion bolt is connected between the upper part of the top channel steel and the top slab layer. The steel reinforcement layer includes vertical steel bars evenly distributed left and right and horizontal steel bars evenly distributed up and down. The corner of the clamping steel bar is abutted between two horizontal steel bars. The clamping steel bar is inserted into the grouting joint and filled with a layer of cement slurry.

[0007] Furthermore, the clamping steel bar has two corners that abut against the two adjacent transverse steel bars, and the corners of the clamping steel bar and the transverse steel bars are fixed together by binding.

[0008] Furthermore, the upper and lower parts of the reinforcing steel layer are welded and fixed to the top channel steel and the bottom channel steel, respectively.

[0009] Furthermore, the clamping steel bars are spaced apart by one or more of the bucket bricks, and the lower end of the top channel steel is bonded and fixed to the concrete layer.

[0010] Furthermore, the two corners of the clamping rebar are both located between two adjacent transverse rebars, and two adjacent clamping rebars are connected together by a transverse rebar.

[0011] Furthermore, the reinforcing bar is inserted into the grout at the middle position of the brick.

[0012] Furthermore, the reinforcing bars are installed at the upper end and slightly above the middle of the original wall.

[0013] The beneficial effects of this application are as follows:

[0014] 1. This utility model reinforces the inner wall portion of the original wall by connecting or filling with a steel reinforcement layer, reinforcing bars, cement grout layer, and concrete layer. The reinforcing bars are inserted at the grouting joints, reducing overall damage to the original wall and enhancing its integrity. Furthermore, the more flexible reinforcement method better meets external building requirements.

[0015] 2. The top channel steel is fixed to the top slab layer with expansion bolts. After the concrete layer is fixed to the lower end of the top channel steel, the drilling and fixing at the original wall location of the top channel steel is removed, thereby further reducing the overall damage to the original wall. The tie rods and cement grout layer provide tensile force to the original wall, providing large-area uniform constraint, concealed construction, and maintaining the integrity of the outer ring of the original wall.
