Description

Technical Field

[0001] This utility model relates to the field of building reinforcement, and in particular to a masonry wall reinforcement structure. Background Technology

[0002] Masonry wall structures are widely used due to their simple construction, convenient construction, and low cost. As buildings age, the tensile, bending, and shear strength of masonry wall structures gradually decreases. Therefore, it is necessary to reinforce old masonry walls to ensure their load-bearing capacity and seismic performance.

[0003] The common method for reinforcing masonry walls in related technologies involves adding steel meshes to both sides of the wall, fixing the meshes to the external wall, and then applying mortar layers to both sides of the masonry wall. However, the lack of a connecting structure between the steel meshes and the masonry wall results in poor stability of the connection, thus affecting the reinforcement effect and requiring improvement.

[0007] Optionally, the limiting sleeve is threaded onto the corresponding end of the anchor rod.

[0008] Optionally, a tightening ring for use with an external wrench is fixedly sleeved on the limiting cylinder.

[0009] Optionally, each of the steel meshes includes multiple supporting steel bars, which are arranged in the transverse and longitudinal directions and welded together. Each of the supporting steel bars has fasteners at both ends for fixing to the external wall.

[0010] Optionally, each of the fasteners includes a fastening anchor and a fastening sleeve. The fastening anchor is used to be driven into the external wall, and the fastening sleeve is movably sleeved on the fastening anchor. The fastening sleeve is used to be sleeved on the corresponding end of the supporting reinforcing bar and welded to the supporting reinforcing bar for fixation.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1 , Figure 2 A masonry wall reinforcement structure includes two vertically arranged steel meshes 1, which are tightly attached to the masonry wall. The reinforcement structure also includes multiple horizontally arranged anchor rods 2, which are arranged in a matrix and pass through the masonry wall. Each anchor rod 2 has a limiting member 3 at both ends for fixing to the corresponding steel mesh 1.

[0020] Reference Figure 1 , Figure 2Each limiting component 3 includes a limiting cylinder 31 and a limiting plate 32. The limiting cylinder 31 passes through the limiting plate 32 and is welded and fixed to the limiting plate 32. The limiting cylinder 31 is used to be sleeved on the corresponding end of the anchor rod 2 and welded and fixed to the anchor rod 2. The limiting plate 32 is used to press the steel mesh 1 tightly against the masonry wall, and the limiting plate 32 can be welded and fixed to the steel mesh 1.

[0021] Reference Figure 1 , Figure 2 The limiting cylinder 31 is threaded onto the corresponding end of the anchor rod 2, and a tightening ring 33 is fixedly fitted on the limiting cylinder 31 for use with an external wrench. In other words, the operator can control the tightening ring 33 to drive the limiting cylinder 31 and the limiting plate 32 to rotate through the wrench, so as to achieve a quick connection between the limiting cylinder 31 and the anchor rod 2.

[0022] When reinforcement of a masonry wall is required, multiple assembly holes are evenly opened in the masonry wall, and multiple anchor rods 2 are inserted into the corresponding assembly holes. Then, the reinforcing mesh 1 is tightly attached to the masonry wall, and the tightening rings 33 at both ends of the anchor rod 2 are rotated until the limiting plates 32 at both ends of the anchor rod 2 press the corresponding reinforcing mesh 1 tightly against the masonry wall. Next, the limiting cylinder 31 is welded and fixed to the anchor rod 2, and the limiting plate 32 is welded and fixed to the corresponding reinforcing mesh 1. Finally, the reinforcing mesh 1 is fixed to the external wall, thus achieving the reinforcement of the masonry wall.

[0023] By installing anchor rods 2 that can pass through the masonry wall, and fixing both ends of the anchor rods 2 to the corresponding steel meshes 1 via limiting members 3, the masonry wall and the two steel meshes 1 are firmly fixed together, thereby improving the connection stability between the steel meshes 1 and the masonry wall, and thus improving the reinforcement effect. Simultaneously, the limiting plate 32 can press the steel meshes 1 tightly against the masonry wall, improving the fit between the steel meshes 1 and the masonry wall and ensuring the reinforcement effect. Furthermore, the limiting cylinder 31 is threadedly connected to the anchor rods 2, allowing the limiting cylinder 31 to be fixed to the anchor rods 2 before welding, facilitating the welding operation of the limiting cylinder 31 and the anchor rods 2.

[0024] Reference Figure 1 , Figure 3 Each steel mesh 1 includes multiple supporting steel bars 11, which are arranged in the transverse and longitudinal directions and welded together to form a mesh structure. Each supporting steel bar 11 has fasteners 12 at both ends, and the fasteners 12 are used to fix it to the external wall.

[0025] Reference Figure 1 , Figure 3Each fastener 12 includes a fastening anchor 121 and a fastening sleeve 122. The fastening anchor 121 is used to nail into the outer wall. The fastening sleeve 122 is movably sleeved on the fastening anchor 121 and can be welded and fixed to the fastening anchor 121. At the same time, the fastening sleeve 122 is used to sleeve on the corresponding end of the supporting steel bar 11 and is welded and fixed to the supporting steel bar 11.

[0026] After the steel mesh 1 is connected to the masonry wall, according to the position of the supporting steel bar 11, the fastening anchor 121 is nailed into the outer wall. Then, the fastening cylinder 122 is pulled to move, so that one end of the fastening cylinder 122 is sleeved on the supporting steel bar 11 and the other end is sleeved on the fastening anchor 121. Subsequently, the fastening cylinder 122 is welded and fixed to the supporting steel bar 11 and the fastening anchor 121 respectively, thus realizing the connection between the supporting steel bar 11 and the outer wall.

[0027] Reference Figure 1 , Figure 3 The fastening cylinder 122 is provided with multiple welding ports 123, which are arranged at equal intervals along the circumference of the fastening cylinder 122 so that the fastening cylinder 122 and the supporting steel bar 11 can be welded at the welding port 123, thereby improving the connection stability between the fastening cylinder 122 and the supporting steel bar 11.
