Abstract
Description
Technical Field
[0001] This utility model relates to the field of wall renovation and repair technology, specifically a steel plate masonry composite wall for repairing bent masonry walls. Background Technology
[0002] In some masonry structure renovation projects, the existing masonry wall is typically reinforced by adding a reinforced concrete slab wall to one side. Because the newly added reinforced concrete slab wall on the reinforced side contains a relatively dense steel mesh, and it is necessary to drill holes in the original masonry wall to install reinforcing bars in a staggered pattern with a spacing of no more than 500mm, the unreinforced side of the wall may experience out-of-plane bending due to the hardening expansion of the concrete and seepage along the drilled holes during concrete pouring. How to quickly repair the deformed wall and improve the compressive, bending, and shear resistance of the repaired masonry wall has become a problem urgently needing to be solved by those skilled in the art. Therefore, this case study was developed to address these issues in depth. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a steel plate masonry composite wall for repairing bent masonry walls, thus solving the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a steel plate masonry composite wall for repairing bent masonry walls, comprising a reinforced concrete slab wall constructed on one side of the original masonry wall, wherein a steel plate is provided on the bent and deformed side of the original masonry wall, the steel plate is arranged parallel to the reinforced concrete slab wall and fixedly connected by through-wall tie rods, and the space between the steel plate and the bent and deformed part of the original masonry wall is filled with grout.
[0005] The steel plates mentioned above are made of Q235 steel and have a rust removal grade of not less than Sa2.5.
[0006] The two ends of the aforementioned through-wall tie rods are assembled and connected to the steel plate and reinforced concrete wall through washers and nuts.
[0007] The nominal diameter of the thread of the aforementioned through-wall tie rod shall not be less than 12 mm.
[0008] The spacing between the adjacent through-wall tie rods mentioned above is 600 mm. Beneficial effects
[0009] This utility model provides a steel plate masonry composite wall for repairing bent masonry walls. It offers the following advantages: This steel plate masonry composite wall for repairing bent masonry walls consists of an existing unilaterally reinforced masonry wall and steel plates. It is used to repair out-of-plane bending of the unreinforced side of a masonry structure when the reinforced concrete hardens and expands due to unilateral reinforcement. By connecting the steel plates to the unilaterally reinforced masonry wall and filling the space between the deformed wall and the steel plates with grout, the deformed wall is repaired, improving its compressive, bending, and shear strength. The construction is simple and quick, saving materials, shortening the construction period, and reducing related costs. Attached Figure Description

[0014] 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.
[0015] Example: Refer to the appendix of the instruction manual. Figure 1-3 As can be seen, this application specifically designs a steel plate 3 masonry composite wall for repairing bent masonry walls. After a reinforced concrete slab wall 2 is added to one side of the original masonry wall 1, the edge 8 of the original masonry wall undergoes bending deformation, forming as shown in the attached specification. Figure 2 and appendix Figure 3The deformed masonry wall edge line 9 shown in the diagram has a steel plate 3 installed on the bent and deformed side of the original masonry wall 1. The specific working principle is as follows: First, determine the length, width, and height of the wall to be repaired. Then, cut the steel plate 3 according to the wall dimensions. After cutting, drill holes in the steel plate 3 according to the location of the through-wall tie rod 4. Then, drill holes at the corresponding positions of the through-wall tie rod 4 on the reinforced side of the wall. Then, stand the steel plate 3 upright, place it in the designed position, and tighten the through-wall tie rod 4. Then, fill the space between the deformed wall and the steel plate 3 with grout 5, and ensure that the grout 5 is fully compacted. The grout 5 should be filled completely to ensure that it hardens and is dense and tightly bonded to the deformed wall. After the grout 5 reaches the designed strength, tighten the through-wall tie rods a second time. The thickness of the steel plate 3 needs to be determined according to the specific situation. Grouting material 5 is used to fill the cavity between steel plate 3 and the original reinforced deformed wall to repair the original deformed wall, improve the compressive, bending and shear resistance of the repaired masonry wall, and the construction is simple and quick, saving materials, shortening the construction period and saving related costs.
[0016] In the specific implementation process, as a preferred setting, the steel plate 3 is made of Q235 material and the rust removal grade is not lower than Sa2.5; the two ends of the through-wall tie rod 4 are assembled and connected to the steel plate 3 and the reinforced concrete wall 2 through the washers 6 and nuts 7; the nominal diameter of the thread of the through-wall tie rod 4 is not less than 12 mm; the spacing between adjacent through-wall tie rods 4 is 600 mm.
