Description

Technical Field

[0001] This utility model relates to the field of protection and reinforcement of exposed brick walls, and in particular to a hook-type tie reinforcement structure for exposed brick walls. Background Technology

[0002] Traditional brick walls are mostly laid using a one-header-one-stretcher or three-header-one-stretcher method. The brick joints are basically continuous horizontally and staggered vertically, with a joint width of 8-10mm. This staggered placement of bricks creates a sense of integrity and results in a better appearance of exposed brick walls.

[0003] With the national policy of vigorously promoting the renovation and upgrading of existing urban buildings, the exposed brick walls of traditional buildings often reflect the historical imprint of the city and are preserved and displayed in the renovation process. Due to their age, traditional exposed brick walls suffer from problems such as poor structural stability and material durability, generally exhibiting insufficient strength and rigidity, such as relatively good brick quality, crumbling mortar in the brick joints, and a loose overall structure.

[0004] Currently, the common method for reinforcing traditional walls is to apply steel mesh or steel frames to both the inner and outer surfaces of the wall, and then clamp them together with through bolts to enhance their overall strength and rigidity. However, the exposed brick exterior must be preserved and its original appearance displayed. Many renovations cannot damage its original appearance, so only minimal and reversible methods can be used. Currently, traditional reinforcement methods for preserving the exposed brick exterior are mainly implemented on the inner wall surface. This typically involves bonding steel mesh or adding drilled holes for rebar installation to bond the mesh to the brick wall. The connection relies primarily on the bond strength between the mesh and the brickwork. This method still suffers from insufficient bond strength for thicker walls or double-layered brick walls, especially for the outer brickwork, which is relatively difficult to secure. Utility Model Content

[0005] The purpose of this utility model is to provide a hook-type bracing reinforcement structure for fair-faced brick walls, which uses an installation component with a straight rod and a hook to install the mesh plate. The hook is set inside the brick to achieve stable installation of the mesh plate.

[0006] To solve the above technical problems, the following technical solution is adopted:

[0007] This utility model provides a hook-type tie reinforcement structure for a fair-faced brick wall. The fair-faced brick wall has an inner wall surface and an outer wall surface. The reinforcement structure includes an installation component and a mesh plate. The mesh plate is set on the inner wall surface. One end of the installation component is installed inside the fair-faced brick wall, and the other end extends to the inner wall surface to install the mesh plate on the inner wall surface.

[0008] The mounting component includes a straight rod and a hook. The hook is located inside the brickwork of the exposed brick wall, and the straight rod is located in the vertical joint of the exposed brick wall. One end of the straight rod extends out from the inner wall surface.

[0009] Optionally, the mounting component is a screw structure with one end bent, and a connecting thread is provided on the straight rod portion. The end of the straight rod portion extending from the inner wall surface passes through the mesh plate, and the mesh plate is fixed by the nut assembly and the straight rod portion.

[0010] Optionally, the mesh panel may also be coated with an interior wall plaster layer.

[0011] Optionally, the vertical joint includes a mortar section and an installation section after the mortar has been removed. The installation section is used to install the hook section into the interior of the brick body. The mortar section has a screw hole from the inner wall surface to the outer wall surface, and the screw hole is used to pass through the straight rod section of the installation component.

[0012] Optionally, a hook hole is provided on the corresponding rotating body within the vertical slit. The hook hole is arranged obliquely and is used to set the hook portion of the mounting component.

[0013] Optionally, two mounting members are provided in one of the vertical seams, and the two mounting members are arranged vertically within one vertical seam, and the vertical seams with the mounting members are staggered on the exposed concrete wall.

[0014] Optionally, the angle between the hook portion and the straight rod portion is less than or equal to ninety degrees.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0016] 1. The fair-faced concrete wall reinforcement structure provided by this utility model uses a mounting piece with a straight rod and a hook to install the mesh. The hook is set inside the brick, which will not damage the surface of the fair-faced concrete wall. The hook on the mounting piece is set inside the brick and has good tensile force, so as to achieve stable installation of the mesh and thus improve the firmness of the fair-faced concrete wall. Different lengths of mounting pieces can be used according to the wall thickness, thereby improving the applicability of the structure. This utility model has a simple structure and low cost.

[0017] 2. The exposed concrete wall reinforcement structure provided by this utility model reduces damage to the wall surface by installing fixed components in the vertical joints. Only a portion of the mortar in the brick joints needs to be removed, without affecting the stability of the wall. By drilling hook holes in the bricks at the upper and lower ends of the vertical joint, the force of the steel mesh on a single vertical joint is ensured to be uniform, while also achieving stable installation of the steel mesh. After the steel mesh is laid on the inner wall surface, the steel tie members are tightened with nut assemblies, forming a mechanical tension between the steel mesh and the bricks. This method of tensioning the force is simple and direct, and the use of evenly distributed points improves the overall strength and rigidity of the combination between the exterior wall bricks and the steel mesh.

[0025] Example 1

[0026] This embodiment provides a hook-type bracing reinforcement structure for fair-faced brick walls, including an installation component 5 and a mesh plate 7. One end of the installation component 5 is set inside the fair-faced brick wall 1, and the other end extends from the inner wall surface 11 of the fair-faced brick wall 1 for installing the mesh plate 7. The end of the installation component 5 extending from the inner wall surface 11 passes through the mesh plate 7 and is provided with a nut assembly 6 at its end. The mesh plate 7 is fixed to the inner wall surface 11 of the fair-faced brick wall 1 by the nut assembly 6. Then, an inner wall plaster layer 9 is applied to the mesh plate 7. The stability of the fair-faced brick wall 1 is improved by the stable installation of the mesh plate 7.

[0027] like Figure 1 As shown, the mounting component 5 is a screw structure with one end bent, including a straight rod part 51 and a hook part 52. The straight rod part 51 is provided with connecting threads, so as to cooperate with the nut assembly 6 to fix the mesh plate 7. The hook part 52 is embedded in the brick body 3. The angle between the hook part 52 and the straight rod part 51 is less than or equal to ninety degrees, so that the entire mounting component 5 is firmly installed on the exposed brick wall 1.

[0028] A portion of the straight rod 51 is set in the vertical joint 2 of the exposed concrete wall 1, and the other portion extends from the vertical joint 2 to the inner wall surface 11 for installing the mesh panel 7. Two mounting pieces 5 are provided in one vertical joint 2, arranged vertically, and the hooks 52 of the two mounting pieces 5 are respectively embedded in the bricks 3 at the upper and lower ends of the vertical joint 2.

[0029] Several mounting parts 5 are provided on the clear water wall 1 for installing the mesh 7. The vertical seams 2 of the mounting parts 5 are staggered on the clear water wall 1 to avoid the mounting parts 5 affecting the stability of the clear water wall 1.

[0030] The sheet metal 7 can be made of materials such as steel, iron, and alloy.

[0031] like Figure 1 , Figure 3 As shown, the vertical joint 2 includes a mortar section and an installation section with some mortar 8 removed from the brick joint. The mortar section has screw holes 81 extending from the inner wall surface 11 to the outer wall surface 12. The screw holes 81 are the same size as the diameter of the straight rod section 51 and are used to pass through the straight rod section 51. The installation section with some mortar 8 removed has hook holes 4 at both ends of the vertical joint 2. The hook holes 4 are the same size as the diameter of the hook section 52 and are used to install the hook section 52. The hook holes 4 are arranged obliquely; the hook holes 4 at the lower end of the vertical joint 2 are inclined downwards towards the inner wall surface 11, and the hook holes 4 at the upper end of the vertical joint 2 are inclined upwards towards the inner wall surface 11. The angle of inclination is the same as the angle between the straight rod section 51 and the hook section 52, facilitating the installation of the mounting component 5 into the vertical joint 2.

[0032] The installation steps for the above-mentioned reinforcement structure are as follows:

[0033] Select several vertical seams 2 on the exposed water wall 1, and arrange the several vertical seams 2 in a staggered and even manner on the exposed water wall 1.

[0034] like Figure 1 and Figure 3 As shown in Figure A, a portion of the brick joint mortar is removed from the selected vertical joint 2 from the outer wall surface 12 towards the inner wall surface 11. After removing a portion of the brick joint mortar 8 from the vertical joint 2, two parallel screw holes 81 are made at the upper and lower ends of the remaining brick joint mortar 8 in the vertical joint 2. The screw holes 81 are used to pass through the straight rod part 51. The direction of the screw holes 81 is from the outer wall surface 12 to the inner wall surface 11, and the size is the same as the diameter of the straight rod part 51 of the mounting part 5.

[0035] Brick hook holes 4 are made on the upper and lower ends of the brick body 3 in the vertical joint 2 after part of the brick joint mortar has been removed. The direction of the hook holes 4 is oblique to the inner wall surface 11, and the size is the same as the diameter of the hook part 52 of the installation part 5. The hook holes 4 are used to install the hook part 52.

[0036] Remove some of the brick joint mortar 8 in the vertical joint 2 to facilitate drilling into the brick body 3 using an electric drill 10, and also to facilitate the entry of the hook part into the hook hole.

[0037] like Figure 3 As shown in Figures B and C, two mounting pieces 5 are installed within a vertical joint 2. One mounting piece 5 has its barb portion 52 pointing downwards, with its straight rod portion 51 extending from the outer wall surface 12 into the screw hole 81. Its bent hook portion 52 is inserted into the barb hole 4 at the lower end of the vertical joint, and its straight rod portion 51 extends out from the inner wall surface 11. The other mounting piece 5 has its barb portion 52 pointing upwards, with its straight rod portion 51 extending from the outer wall surface 12 into the screw hole 81. Its bent hook portion 52 is inserted into the barb hole 4 at the upper end of the vertical joint 2, and its straight rod portion 51 extends out from the inner wall surface 11.

[0038] like Figure 3 As shown in the diagram, after the installation parts 5 are installed in all the selected vertical seams 2, the mesh 7 is installed on the inner wall surface 11. The extended straight rod part 51 is set through the mesh 7, and the nut assembly 6 is installed at the end of the straight rod part 51 to stably install the mesh 7 on the inner wall surface 11.

[0039] Finally, apply interior wall plaster layer 9 to the surface of the mesh 7, covering the mesh 7.

[0040] The exposed brick wall reinforcement structure provided in this embodiment is a direct and efficient force-bearing reinforcement structure that ensures the integrity of the wall. Without damaging the appearance of the exterior brickwork and retaining the original technical methods of the interior wall, it eliminates the need for drilling and piercing rebar installation, thus simplifying the construction process.

[0041] In response to the characteristics of staggered joint masonry in exposed brick walls, the vertical joints are used as the locations for implementing wall ties, without touching the outer surface of the brickwork. The reinforcement structure ties provided in this embodiment offer a simple and direct stress-bearing method, implemented using evenly distributed points, which can improve the overall strength and rigidity of the bond between the brickwork 3 and the mesh 7 on the outer wall surface 12.

[0042] The reinforcement structure provided in this embodiment is suitable for reinforcing walls that are relatively thick and constructed with double layers of brickwork, thereby improving the structural applicability.

[0043] This embodiment provides effective technical support for both structural reinforcement and exterior preservation of old buildings, which can not only solve the problem of repairing traditional buildings, but also expand the use of traditional buildings in old urban areas.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
