Abstract
Description
Technical Field
[0001] This utility model relates to the field of brick masonry wall reinforcement technology, and more specifically, to an earthquake-resistant reinforcement structure for existing brick masonry walls. Background Technology
[0002] Brick masonry refers to a monolithic material constructed using bricks and mortar. It is one of the most widely used building materials. Brick masonry walls are walls built using brick masonry methods. Compared to using cement, steel bars, and wood, brick masonry is less expensive. At the same time, materials such as bricks and concrete have good durability and weather resistance. Brick masonry walls are very common in my country due to their good durability.
[0003] Based on the above, the inventors have discovered that many existing brick masonry structures in my country suffer from brick weathering and mortar powdering due to their age, resulting in insufficient wall load-bearing capacity. Under earthquake action, these structures are prone to structural damage or even collapse, necessitating reinforcement of the brick walls to improve their seismic performance. Therefore, in view of this, the inventors have researched and improved the existing structures, providing a seismic reinforcement structure for existing brick masonry walls to achieve a more practical purpose. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a seismic reinforcement structure for existing brick masonry walls. This solution features a surface layer that bonds well with the brick wall base, improving the wall failure mode and increasing the wall's ductility. Simultaneously, the wire mesh construction further enhances the bonding performance between the surface layer and the brick masonry wall, enabling the surface layer and the brick wall substrate to work together and preventing surface layer peeling. This effectively reinforces the brick masonry wall against seismic forces. Furthermore, the inclusion of clamping components improves the stability of the wire mesh structure during construction, preventing displacement and bending, and ensuring subsequent bonding effectiveness.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] An earthquake-resistant reinforcement structure for existing brick masonry walls includes a wall body. The wall body has several fixing nails snapped together inside. One end of each fixing nail is movably connected to a perforated block. A vertical steel wire and a horizontal steel wire are inserted through the perforated block. One end of the perforated block is fixedly connected to a snap-fit sleeve. A set of positioning rods is fixedly connected to the side of the snap-fit sleeve. A clamping mechanism is centrally located on the opposite faces of two adjacent positioning rods.
[0009] The clamping mechanism includes two symmetrically arranged clamps. An anti-detachment ring is fixedly connected to the outer side of each clamp. A pair of snap-fit connectors are fixedly connected to the inner side of one of the clamps, and a pair of snap-fit grooves are opened on the inner side of the other clamp.
[0010] Furthermore, a plastering layer is fixedly connected to the outer side of the wall, and the plastering layer covers vertical and horizontal steel wires.
[0011] Furthermore, the wall is composed of several bricks with dimensions of 240mm×115mm×53mm, and the thickness of the plaster layer ranges from 8 to 12mm.
[0012] Furthermore, the vertical steel wires and horizontal steel wires are arranged in an alternating manner, with the vertical steel wires located behind the horizontal steel wires, and the spacing between two adjacent fixing nails is in the range of 200-300mm.
[0013] Furthermore, the inner end of the positioning rod is engaged with the end face of the fixing nail.
[0014] Furthermore, the anti-detachment ring is located on the side of the positioning rod near the inside, and the anti-detachment ring is slidably connected to the positioning rod, with the snap-fit connector and the snap-fit groove being snap-fitted together.
[0015] Furthermore, the vertically arranged sleeve is adapted to the vertical steel wire, and the horizontally arranged sleeve is adapted to the horizontal steel wire.
[0016] 3. Beneficial effects
[0017] Compared with existing technologies, the advantages of this utility model are:
[0018] (1) In this scheme, the fixing nail is inserted into the hole groove, then the angle of the perforated block is adjusted, and then the snap sleeve is snapped to the outer end of the perforated block. Then, the vertical steel wire and the horizontal steel wire are passed through in sequence. Finally, a plaster layer with a thickness of 8 to 12 mm is manually pressed and applied to complete the reinforcement construction of the brick masonry wall. Compared with the existing technology, the setting of a surface layer that is well bonded to the brick wall base improves the wall failure mode and increases the wall ductility. At the same time, the steel wire mesh construction measures can further improve the bonding performance between the surface layer and the brick masonry wall, so that the surface layer and the brick wall base work together to avoid the phenomenon of surface layer peeling, and effectively strengthen the brick masonry wall against seismic forces.
[0019] (2) By setting up a clamping mechanism, after the steel wire is installed, the clamping head is clamped to the clamping slot, so that the two symmetrical clamps are fixed on the outside of the corresponding steel wire, and the steel wire is clamped and fixed. Compared with the existing technology, setting up a clamping component improves the stability of the steel wire mesh structure during construction, avoids the problem of displacement and bending, and ensures the subsequent bonding effect.

[0027] Example:
[0028] Please see Figure 1-5 An earthquake-resistant reinforcement structure for existing brick masonry walls includes a wall 1. Several fixing nails 2 are snapped together inside the wall 1. A perforated block 3 is movably connected to one end of the fixing nail 2 on the outer side. A vertical steel wire 4 and a horizontal steel wire 5 are inserted through the perforated block 3. A snap-fit sleeve 6 is fixedly connected to one end of the perforated block 3 on the outer side. A set of positioning rods 7 is fixedly connected to the side of the snap-fit sleeve 6. A clamping mechanism 8 is arranged in the middle of the opposite face of two adjacent positioning rods 7.
[0029] The clamping mechanism 8 includes two symmetrically arranged clamps 9. An anti-detachment ring 10 is fixedly connected to the outer side of the clamps 9. A pair of snap-fit connectors 11 are fixedly connected to the inner side of one of the clamps 9, and a pair of snap-fit grooves 12 are opened on the inner side of the other clamp 9. The clamping mechanism 8 is provided to ensure the stability of the steel wire insertion.
[0030] See Figure 5A plastering layer 13 is fixedly connected to the outside of the wall 1. The plastering layer 13 covers vertical steel wires 4 and horizontal steel wires 5. The thickness of the plastering layer 13 is 8 to 12 mm, which is manually pressed and applied.
[0031] See Figure 5 The wall 1 is composed of several bricks with dimensions of 240mm×115mm×53mm, and the plaster layer 13 has a thickness ranging from 8 to 12mm.
[0032] The thickness of the topcoat layer 13 is usually 12mm.
[0033] See Figure 1 The vertical steel wire 4 and the horizontal steel wire 5 are staggered, with the vertical steel wire 4 located behind the horizontal steel wire 5. The spacing between two adjacent fixing nails 2 is 200-300mm. After the wall 1 is formed, holes and grooves are opened in the wall 1 and cleaned. Then, the fixing nails 2 are inserted into the holes and grooves, so that the spacing between adjacent fixing nails 2 is 200-300mm. Then, the angle of the perforated block 3 is adjusted so that the horizontal and vertical positions of the perforated block 3 are aligned with the perforated blocks 3 in the adjacent positions. First, the vertical steel wire 4 is passed through in sequence, so that it passes through several perforated blocks 3 in the same vertical position. Then, the horizontal steel wire 5 is passed through in sequence, so that it passes through several perforated blocks 3 in the same horizontal position.
[0034] See Figure 2 The inner end of the positioning rod 7 is engaged with the end face of the fixing nail 2, and the engaging sleeve 6 is engaged with the outer end of the perforated block 3. At the same time, the positioning rod 7 is engaged with the fixing nail 2, so that the position of the perforated block 3 is fixed.
[0035] See Figure 4 The anti-detachment ring 10 is located on the side of the positioning rod 7, close to the inside, and is slidably connected to the positioning rod 7. The snap-fit connector 11 and the snap-fit groove 12 are snap-fitted together. The anti-detachment ring 10 plays a role in limiting movement and ensuring the stability of the movement of the sleeve 9.
[0036] See Figure 4 The vertically set clamp 9 is adapted to the vertical steel wire 4, and the horizontally set clamp 9 is adapted to the horizontal steel wire 5. The clamp 9 is engaged with the clamping groove 12 through the clamping connector 11, so that the two symmetrical clamps 9 are fixed on the outside of the corresponding steel wires to clamp and fix the steel wires.
[0037] In use: Construct wall 1 using bricks of a certain specification. The masonry material is a mixture of MU10 sintered common bricks and M1 low-strength clay mortar. Lay the bricks in a one-header-one-stretcher pattern, with an average mortar joint thickness of 10mm and a mortar fullness of approximately 80%. After wall 1 is formed, create grooves in wall 1 and clean the grooves. Then, insert fixing nails 2 into the grooves, ensuring a spacing of 200-300mm between adjacent fixing nails 2. Next, adjust the angle of the perforated blocks 3 so that their horizontal and vertical positions are aligned with adjacent perforated blocks 3. Finally, engage the locking sleeve 6 with the outermost end of the perforated block 3. Simultaneously, the positioning rod 7 is engaged with the fixing nail 2 to fix the position of the perforated block 3. Then, the vertical steel wire 4 is sequentially threaded through several perforated blocks 3 at the same vertical position. Then, the horizontal steel wire 5 is sequentially threaded through several perforated blocks 3 at the same horizontal position. After the steel wire installation is completed, the clamping connector 11 is engaged with the clamping groove 12 to fix the two symmetrical clamps 9 on the outside of the corresponding steel wires, thus clamping and fixing the steel wires. The anti-detachment ring 10 plays a role in limiting movement and ensuring the stability of the movement of the clamps 9. Finally, a plaster layer 13 with a thickness of 8-12mm is manually applied to complete the reinforcement construction of the brick masonry wall.
