Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a device for the renovation and reinforcement of old urban community buildings. Background Technology

[0002] Building walls suffer various forms of damage under different conditions, resulting in varying degrees of damage, such as cracks of different sizes and shapes, or even wall tilting and collapse. In such cases, wall reinforcement is necessary. Currently, old urban community buildings commonly suffer from structural aging, insufficient seismic performance, and exterior wall cracks. Traditional reinforcement methods (such as increasing cross-sections and external steel cladding) are complex, costly, and disruptive to residents' lives. While large "L"-shaped panels are sometimes used for support, these methods either have limited effectiveness in improving the overall tensile strength of the wall, or require excessive materials. Existing reinforcement devices often lack flexibility, are difficult to adapt to different wall structures, have insufficient anchoring stability, and cause significant damage to the wall. Therefore, there is an urgent need for a convenient and adaptable reinforcement device that can improve structural strength while maintaining construction efficiency and aesthetics. Utility Model Content

[0003] In view of the problems in the prior art, this utility model proposes a device for the renovation and reinforcement of old urban community buildings.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A reinforcement device for the renovation of old urban community buildings includes a vertical reinforcement plate and a horizontal reinforcement plate. The external side of the vertical reinforcement plate is equipped with a fixing plate, and the fixing plate is equipped with hinge seats I arranged vertically at intervals. Anchor rods are anchored on the outer side of the hinge seats I. A wire mesh is laid on the inner side of the vertical reinforcement plate close to the outer wall. The anchor rods are embedded and anchored in the wall through the fixing plate, the vertical reinforcement plate, and the wire mesh. The horizontal reinforcement plate is a square plate with hinge seats II corresponding to the front and back of its upper end. A first support rod and a second support rod are connected between the two hinge seats I and the hinge seats II, respectively. Expansion bolts embedded in the wall are provided at the four corners of the horizontal reinforcement plate. Anchor rods are anchored in the middle of the hinge seats II.

Detailed Implementation

[0020] 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.

[0021] Example 1

[0022] like Figure 1-4 As shown, this embodiment provides a reinforcement device for the renovation of old urban community buildings, including a vertical reinforcement plate 1 and a horizontal reinforcement plate 3. The vertical reinforcement plate 1 is provided with a fixing plate 2 on its exterior. The fixing plate 2 is provided with hinge seats I 21 arranged vertically at intervals. Anchor rods 7 are anchored on the outer side of the hinge seats I 21 respectively. A wire mesh 8 is laid on the inner side of the vertical reinforcement plate 1 close to the outer wall. The anchor rods 7 are embedded and anchored in the wall body through the fixing plate 2, the vertical reinforcement plate 1 and the wire mesh 8. The horizontal reinforcement plate 3 is a square plate with hinge seats II 31 corresponding to the front and back of its upper end. The two hinge seats I 21 and the hinge seats II 31 are respectively connected to a first support rod 5 and a second support rod 6. Expansion bolts 4 embedded in the wall are provided at the four corners of the horizontal reinforcement plate 3. Anchor rods 7 are anchored in the middle of the hinge seats II 31.

[0023] The anchor bolt component 7 includes an anchor bolt 70, a nut 71, a preload spring 72, a friction-reducing pad 73, and a tray 74. The anchor bolt 70 is anchored in the wall, and the tail of the anchor bolt 70 is locked by the nut 71. The tray 74 is placed on the mating surface of the fixing plate 2. The friction-reducing pad 73 is installed between the tray 74 and the nut 71. The preload spring 72 is installed between the nut 71 and the friction-reducing pad 73.

[0024] The anchor bolt component 7 also includes a limiting steel band 75, which is located below the tray 74. When the nut 71 pre-tightens the anchor bolt 70, the tray 74 presses against the end face of the limiting steel band 75.

[0025] The front end of the anchor bolt 70 is a twisted or wavy steel rod.

[0026] Anchor 70 is a grouting anchor, with cement grout or water glass injected into the anchor hole.

[0027] The anchor rod 70 is 10-15cm long.

[0028] The first support rod 5 and the second support rod 6 are detachably connected between the hinge seat I 21 and the hinge seat II 31.

[0029] The horizontal reinforcing plate 3 has a through hole 32 in the center and bolt holes at the four corners.

[0030] The vertical reinforcement plate 1 is a reinforcement component that is installed vertically on the wall, and the horizontal reinforcement plate 3 is a square reinforcement plate that is installed horizontally on the wall; the fixing plate 2 is set outside the vertical reinforcement plate 1 and is used to connect the anchor rod and the support rod; the hinge seat I21 is a hinge point arranged vertically on the fixing plate 2 and is used to connect the support rod.

[0031] Hinge seat II 31 is a hinge point on the horizontal reinforcing plate 3, used to connect the support rod;

[0032] The through hole 32 is a hole in the center of the horizontal reinforcing plate 3, used to pass through the anchor rod.

[0033] Bolt holes are located at the four corners of the horizontal reinforcing plate 3 for installing expansion bolts.

[0034] The first support rod 5 is an oblique support member connecting the hinge seat I 21 and the hinge seat II 31. The second support rod 6 is another oblique support member symmetrically arranged with the first support rod 5. The anchor rod 7 is an anchoring component that passes through the fixing plate 2, the vertical reinforcement plate 1 and the wire mesh 8. The anchor rod 70 is the main load-bearing member embedded in the wall. The nut 71 is used to lock the fastener at the tail of the anchor rod 70. The preload spring 72 provides dynamic preload force to prevent loosening. The friction-reducing pad 73 reduces the friction between the nut 71 and the tray 74. The tray 74 distributes the anchor rod pressure to the fixing plate 2. The limiting steel band 75 restricts the displacement of the tray 74 and enhances stability. The wire mesh 8 is laid on the inner side of the vertical reinforcement plate 1 to enhance the crack resistance of the wall.

[0035] The modular design (vertical and horizontal reinforcement plates + support rods) and multiple anchoring (anchor rods + expansion bolts) achieve efficient reinforcement of old walls, combining flexibility, stability and ease of construction.

[0036] Specifically, the new type of vertical and horizontal reinforcing plates are connected by hinged support rods to form a spatially stable frame. The layout can be freely adjusted according to the wall size. Anchor rods penetrate the fixing plate, vertical reinforcing plate and wire mesh to form an overall anchoring system, dispersing stress to the depth of the wall. Horizontally, expansion bolts are fixed to the anchor rods in different areas to reduce concentrated damage to the wall. Wire mesh covers cracks to inhibit further cracking of the wall surface.

[0037] The above description is merely an illustrative example of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined in the claims, all of which should fall within the protection scope of this utility model.
