Description

Technical Field

[0001] This utility model relates to the technical field of wall reinforcement devices, specifically a wall reinforcement device for old city renovation. Background Technology

[0002] In urban renewal, wall reinforcement is a core aspect of ensuring building safety. Due to their age, old buildings often have walls made of brick, adobe, or early concrete. Over time, these walls are affected by natural weathering, foundation settlement, and accumulated loads, resulting in problems such as loose bricks and stones, weathered mortar, and expanding cracks. Some walls even exhibit tilting and insufficient load-bearing capacity, posing serious safety hazards and threatening the safety of residents and users.

[0003] Traditional wall reinforcement methods often involve overall enclosure or partial demolition and alteration, which not only have long construction cycles and high costs, but also easily damage the historical appearance and structural integrity of old city buildings. For example, when brick and stone walls are directly reinforced with concrete, secondary cracking is likely to occur due to the mismatch in material stiffness; simply relying on external supports is insufficient to solve the problem of internal looseness of the wall, resulting in poor durability of the reinforcement effect and making it difficult to meet the requirements of "restoring the old as it was" and structural safety in old city renovation.

[0004] With the upgrading of urban renewal concepts, higher requirements are placed on the flexibility, adaptability, and protective properties of wall reinforcement devices. Currently, there are often problems such as excessive rigidity of component connections, inability to adapt to wall size errors, and insufficient fit with the wall, resulting in significant stress concentration after reinforcement and even exacerbating wall damage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figure 1-3As shown, an embodiment of this utility model proposes a wall reinforcement device for urban renewal, including a triangular connecting block 1. The triangular connecting block 1 has a positioning and mounting hole 2. An expansion bolt passes through the positioning and mounting hole 2 to fix the triangular connecting block 1 on the reinforced wall. The triangular connecting block 1 is the core connecting component of the device. It is fixed to the wall by the expansion bolt passing through the positioning and mounting hole 2, providing an installation base for other components.

[0025] The rear end of the triangular connecting block 1 has two mounting slots 3, which provide insertion space for the reinforcing rod 4. The vertical design allows the reinforcing rod 4 to form support in both longitudinal and transverse directions, enhancing the stability of the structure.

[0026] A reinforcing rod 4 is inserted into the mounting groove 3 and fixed to the triangular connecting block 1 by bolts. The rectangular structure can form a surrounding support for the wall, disperse the force on the wall, and improve the overall load-bearing capacity of the wall.

[0027] The triangular part of the triangular connecting block 1 is integrally formed with a grid plate 5, which serves as the mounting carrier for the vertical rod 6, stably fixing the vertical rod 6 to the triangular connecting block 1 and enhancing the connection strength between the vertical rod 6 and the triangular connecting block 1.

[0028] Vertical rods 6 are fastened between the two grid plates 5 by bolts. The vertical rods 6 have positioning holes 7, and horizontal rods 8 are fastened in the positioning holes 7 by bolts. The vertical rods 6 serve as longitudinal support components and cooperate with the horizontal rods 8 to form a crisscross reinforcement structure. The positioning holes 7 can flexibly adjust the installation position of the horizontal rods 8 to adapt to the reinforcement needs of different walls.

[0029] The working principle of this old city renovation wall reinforcement device is as follows: First, the triangular connecting block 1 is fixed to the wall to be reinforced by expansion bolts passing through the positioning mounting holes 2 on the triangular connecting block 1, serving as the basic fixing component of the device; the mutually perpendicular and non-connected mounting slots 3 at the rear end of the triangular connecting block 1 are used to insert the reinforcement rods 4, and the triangular connecting block 1 and the reinforcement rods 4 are adjusted and fixed by bolts through their respective screw holes. The four reinforcement rods 4 and the four triangular connecting blocks 1 form a rectangular structure, which supports and reinforces the wall from the overall frame; at the same time, the vertical rods 6 are installed between the integrally formed grid plates 5 at the triangular part of the triangular connecting block 1 by bolts. The positioning holes 7 on the vertical rods 6 cooperate with the threaded holes 9 at both ends of the horizontal rods 8, and the horizontal rods 8 are fastened to the vertical rods 6 with bolts, forming a crisscross reinforcement structure, which further enhances the stability and load-bearing capacity of the wall.

[0030] like Figure 2As shown, in some embodiments, the two mounting slots 3 are perpendicular to each other and not connected; the vertical design can be adapted to the horizontal and vertical reinforcing rods 4 respectively, so that the reinforcing rods 4 can be arranged along the horizontal and vertical directions of the wall to form a cross-shaped basic support frame, which disperses the force on the wall from different directions and improves the structural stability.

[0031] like Figure 2 As shown, in some embodiments, the four reinforcing rods 4 and the four triangular connecting blocks 1 form a rectangle; this rectangular structure, together with the subsequent vertical rods 6 and horizontal rods 8 forming a longitudinal and transverse reinforcement system, further strengthens the integrity of the wall and effectively addresses the problem of insufficient load-bearing capacity caused by aging and loosening of the old city wall.

[0032] like Figure 1 As shown, in some embodiments, the triangular connecting block 1 is provided with screw holes, and the two ends of the reinforcing rod 4 are provided with screw holes. The reinforcing rod 4 and the triangular connecting block 1 are adjusted and fixed by bolts passing through. This connection method gives the reinforcement device a certain degree of flexibility. If the wall undergoes slight deformation later, the bolt connection can buffer the stress within a certain range, reduce the rigid damage of the device to the wall, and facilitate later maintenance or disassembly and adjustment.

[0033] like Figure 2 As shown, in some embodiments, a plurality of positioning holes 7 are provided on the vertical rod 6; the plurality of positioning holes 7 provide multiple installation points for the horizontal rod 8, so that the height of the horizontal rod 8 can be flexibly adjusted according to the wall reinforcement requirements.

[0034] like Figure 3 As shown, in some embodiments, the two ends of the horizontal bar 8 are provided with threaded holes 9, and the bolts are fastened to the horizontal bar 8 and the vertical bar 6 through the positioning holes 7 into the threaded holes 9; the cooperation of the threaded holes 9 with the positioning holes 7 and the bolts provides a detachable rigid connection for the horizontal bar 8 and the vertical bar 6, ensuring that the two are firmly connected and forming a crisscrossing grid-like reinforcement structure, which significantly improves the overall stability and deformation resistance of the wall.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
