Description

Technical Field

[0001] This utility model relates to the field of corner crack reinforcement technology, specifically a corner crack reinforcement device for masonry walls. Background Technology

[0002] Masonry walls are walls constructed using blocks and mortar through specific masonry methods. Blocks typically include solid bricks, hollow bricks, lightweight aggregate concrete blocks, hollow concrete blocks, rubble masonry, and cobblestone. Mortar typically includes mixed mortar and cement mortar. At the corners of masonry walls, reinforcement devices are usually used to prevent cracks from forming.

[0003] For example, Chinese patent application number CN202421519731.2 discloses a masonry wall corner crack reinforcement device, which includes a reinforcement component for reinforcing the masonry wall body. The reinforcement component includes two symmetrical first angle steels and two symmetrical second angle steels, with one first angle steel and one second angle steel forming a group. The first angle steels are positioned at the corner of the masonry wall body. This utility model, by setting the reinforcement component, enables the device to effectively reinforce the corner of the masonry wall when reinforcing corner cracks, preventing the crack from widening and achieving the purpose of effectively protecting the masonry wall body. Moreover, the reinforcement device is relatively simple and quick to install and disassemble, making it highly practical.

[0004] However, in actual use, the included angle of the first angle steel and the second angle steel in the above device is fixed. When it is necessary to reinforce the corner of the masonry wall with different included angles, the first angle steel and the second angle steel cannot adjust the included angle to adapt to different corners, which has limitations and reduces the applicability of the device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a masonry wall corner crack reinforcement device. By moving the keel steel frame, the two ends of the side steel plates are tilted and rotated, which in turn causes the reinforcement steel plates to tilt and rotate around the second fixed rod. This facilitates the adjustment of the included angle between the two reinforcement steel plates, allowing them to abut against the two side walls of the masonry wall corner body to reinforce the cracks. This device is suitable for reinforcing masonry wall corner bodies with different included angles, thus expanding its applicability and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a masonry wall corner crack reinforcement device, including a U-shaped fixing frame disposed on one side of the main body of the masonry wall corner;

[0007] The U-shaped fixing frame is equipped with a reinforcement component for reinforcing the main body of the masonry wall corner at different angles;

[0008] The reinforcement component includes a keel steel frame, the center of which is located inside a U-shaped fixed frame. A first fixing rod is provided through both the front and rear ends of the keel steel frame. A side steel plate is fixed between the top and bottom ends of the first fixing rod, and the first fixing rod is rotatably mounted on the keel steel frame. A third fixing rod is fixed between the top and bottom ends of the side steel plate on the side away from the first fixing rod, and a reinforcement steel plate is provided through the third fixing rod.

[0009] Preferably, the reinforcing steel plate is rotatably mounted on the third fixed rod, and the same second fixed rod is provided through the side of the two reinforcing steel plates that are close to each other. Both reinforcing steel plates are rotatably mounted on the second fixed rod, so that the two reinforcing steel plates can rotate around the same second fixed rod to adjust the included angle between the two reinforcing steel plates to reinforce the main body of the masonry wall corner at different included angles.

[0010] Preferably, the top and bottom ends of the second fixing rod are fixedly located between the inner top and inner bottom ends of one side of the U-shaped fixing frame, which facilitates the rotation of the two reinforcing steel plates around the second fixing rod.

[0011] Preferably, the keel steel frame is provided with two telescopic rods distributed front and back on the side near the reinforcing steel plate. Both ends of the telescopic rods are rotatably provided with hinge seats. The two hinge seats are respectively fixed on one side of the keel steel frame and the other side of the reinforcing steel plate. This allows the position of the reinforcing steel plate to be limited and supported by adjusting the length of the telescopic rods during the movement of the keel steel frame, while also allowing the two ends of the telescopic rods to rotate and tilt around the two hinge seats.

[0012] Preferably, the top and bottom of the U-shaped fixing frame are provided with several evenly distributed threaded holes, and the top center and bottom center of the keel steel frame are connected by threaded through threaded holes for fixing the U-shaped fixing frame and the keel steel frame. This facilitates the use of the keel steel frame by unscrewing the wing bolts, pulling the keel steel frame along the U-shaped fixing frame, and then fixing the position of the keel steel frame by screwing the wing bolts into the threaded holes.

[0013] Preferably, a handle is fixedly provided at the center of the side of the keel steel frame away from the reinforcing steel plate, so that the keel steel frame can be moved along the U-shaped fixed frame by manually pulling the handle.

[0014] Compared with the prior art, this utility model provides a device for reinforcing corner cracks in masonry walls, which has the following beneficial effects:

[0015] This invention uses a handle to move the keel steel frame horizontally along the inside of the U-shaped fixed frame, causing the two ends of the side steel plates on the keel steel frame to tilt and rotate. This causes the reinforcing steel plate to tilt and rotate around the second fixed rod, and also causes the telescopic rod to stretch, so that the two ends rotate around the two hinge seats respectively, thereby limiting the position of the reinforcing steel plate. This makes it easy to adjust the included angle between the two reinforcing steel plates, so that the two reinforcing steel plates abut against the two side walls of the masonry wall corner body to reinforce the cracks. This invention is convenient for reinforcing the masonry wall corner body with different included angles, thus improving its applicability. Attached Figure Description
