Description

Technical Field

[0001] This utility model relates to the field of wall repair technology, and in particular to a composite fiber mesh reinforcement structure for old walls. Background Technology

[0002] Traditional reinforcement techniques, such as reinforced concrete cladding and steel plate reinforcement, can improve strength, but they have drawbacks such as complex construction, increased weight, and impact on building appearance. In recent years, fiber-reinforced polymer (FRP) composites have been increasingly used in structural reinforcement due to their advantages of being lightweight, high-strength, and corrosion-resistant.

[0003] The composite fiber mesh reinforcement structure for old walls uses a polymer to bond three layers of fiber mesh with cement-based slurry, and then repeatedly rolls the concrete to allow it to penetrate. However, because the three layers of fiber mesh are stacked together, the concrete cannot fully penetrate, thus affecting the wall reinforcement. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a composite fiber mesh reinforcement structure for old walls, which aims to improve the problem that concrete cannot fully penetrate the three-layer fiber mesh and the wall.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite fiber mesh reinforcement structure for old walls, comprising a fiberglass mesh, the outer wall of which is slidably connected to a wall, a first fixing frame slidably connected to the outer wall of the fiberglass mesh, first spring clips fixedly connected to both the upper and lower ends of the first fixing frame, an aramid fiber mesh slidably connected to the outer wall of the first fixing frame, a plurality of first fixing nails slidably connected to the inner wall of the wall, a plurality of second fixing nails slidably connected to the inner wall of the wall, baffles slidably connected to the outer wall of the second fixing nails, a second fixing frame slidably connected to the outer wall of the aramid fiber mesh, a polyvinyl alcohol fiber mesh slidably connected to the outer wall of the second fixing frame, a plurality of second spring clips fixedly connected to both the upper and lower ends of the second fixing frame, a plurality of third spring clips fixedly connected to the outer wall of the second fixing frame, and a corner fixing assembly provided on the outer wall of the fiberglass mesh.

[0006] Through the above technical solution: the glass fiber mesh and the aramid fiber mesh are slidably connected to the outer wall of the first fixing frame, the baffle is slidably connected to the outer wall of the aramid fiber mesh, and the first fixing frame is fixed to the wall by multiple first fixing nails, thus fixing the glass fiber mesh and the aramid fiber mesh. The second fixing frame is fixed to the first fixing frame and the wall by multiple second fixing nails and the baffle, thus fixing the polyvinyl alcohol fiber mesh. There are gaps between the glass fiber mesh, the aramid fiber mesh and the polyvinyl alcohol fiber mesh, which can facilitate the effect of concrete penetration and fixing.

[0007] As a further description of the above technical solution:

[0008] Preferably, the corner fixing assembly includes a first support frame, which is slidably connected to the outer wall of the fiberglass mesh. The upper and lower ends of the first support frame are slidably connected to a second support frame and a third support frame. A plurality of second fixing nails are slidably connected to the inner wall of the third support frame, and a plurality of baffles are slidably connected to the outer wall of the third support frame.

[0009] The above technical solution involves fixing the first, second, and third support frames to the wall using the second fixing nail and the baffle, allowing the first, second, and third support frames to fix the fiberglass mesh, aramid fiber mesh, and polyvinyl alcohol fiber mesh at right angles to the wall, facilitating the bending of the three fiber meshes.

[0010] As a further description of the above technical solution:

[0011] Preferably, the second spring clip is slidably connected to the outer wall of the first fixing frame, and the second spring clip is slidably connected to the outer wall of the polyvinyl alcohol fiber mesh.

[0012] The above technical solution involves clamping the upper and lower ends of the polyvinyl alcohol fiber mesh with a second spring clip, enabling the second fixing frame to move the polyvinyl alcohol fiber mesh and allowing the second spring clip to slide on the outer walls of the upper and lower ends of the first fixing frame, thereby facilitating the positioning of the second fixing frame.

[0013] As a further description of the above technical solution:

[0014] Preferably, a plurality of the first fixing nails penetrate the inner wall of the first fixing frame and are slidably connected to the wall, and a plurality of the second fixing nails penetrate the inner wall of the first fixing frame and are slidably connected to the wall.

[0015] Through the above technical solution: the first fixing frame is penetrated through its inner wall by multiple first fixing nails, and the second fixing frame is penetrated through its inner wall by multiple second fixing nails, so that the first fixing nails fix the first fixing frame to the wall through the baffle, and the second fixing nails fix the second fixing frame to the wall through the baffle.

[0019] As a further description of the above technical solution:

[0020] Preferably, the fiberglass mesh is slidably connected to the outer wall of the wall and the first support frame, the aramid fiber mesh is slidably connected to the outer walls of the first and second support frames, and the polyvinyl alcohol fiber mesh is slidably connected to the outer walls of the second and third support frames.

[0021] The above technical solution involves fixing the third support frame and the second support frame with the polyvinyl alcohol fiber mesh, the second support frame and the first support frame with the aramid fiber mesh, and the first support frame and the wall with the glass fiber mesh, thereby fixing the glass fiber mesh, aramid fiber mesh and polyvinyl alcohol fiber mesh at right angles.

[0022] As a further description of the above technical solution:

[0023] Preferably, one of the first support frames is slidably connected to the outer walls of the aramid fiber web and the polyvinyl alcohol fiber web, and one of the second support frames is slidably connected to the outer walls of the glass fiber web and the aramid fiber web.

[0024] Through the above technical solution: at another right angle, the aramid fiber web and the polyvinyl alcohol fiber web are bent at the right angle by the second support frame, so that there is a gap between the glass fiber web, the aramid fiber web and the polyvinyl alcohol fiber web.

[0025] As a further description of the above technical solution:

[0026] Preferably, a plurality of first fixing nails penetrate the inner walls of the first support frame and the second support frame and are slidably connected to the wall; a plurality of second fixing nails penetrate the inner walls of the first support frame and the second support frame and are slidably connected to the wall; and a plurality of first fixing nails penetrate the inner walls of the fiberglass mesh, aramid fiber mesh and polyvinyl alcohol fiber mesh and are slidably connected to the wall.

[0027] The above technical solution allows the second fixing nail to pass through the first support frame, the second support frame, and the third support frame at a right angle, thereby fixing the fiberglass mesh, aramid fiber mesh, and polyvinyl alcohol fiber mesh. At another corner, the first fixing nail passes through the first support frame and the second support frame to fix the fiberglass mesh, aramid fiber mesh, and polyvinyl alcohol fiber mesh, thus facilitating the bending of the fiber mesh.
