Technical Field
[0001] This utility model relates to the field of wall reinforcement technology, specifically a wall reinforcement device for masonry structure houses. Background Technology
[0002] Many old houses in my country were designed without any earthquake resistance features or were built based on early earthquake resistance standards. As a result, the earthquake resistance performance of these houses does not meet the current assessment standards. Such houses are deficient in various aspects of earthquake resistance and are prone to collapse when faced with strong earthquakes that exceed the local seismic fortification intensity, causing a large number of casualties and posing safety hazards.
[0003] Masonry structures refer to the vertical load-bearing structures such as walls or beams in buildings, which are formed by stacking bricks and concrete. This method of building houses has the advantages of low construction requirements, convenient material transportation, and low cost. However, due to the brittleness of bricks and the weak overall structure due to the connection method of concrete, masonry structures have relatively poor seismic performance and are more prone to collapse in strong earthquakes. Therefore, there is an urgent need for a masonry structure wall reinforcement device to strengthen the seismic resistance of old houses. Utility Model Content

[0032] Reference Figure 1 and Figures 5-6 , Figure 1 This is a schematic diagram of the structure of this utility model; Figure 5 This is a schematic diagram of the ground beam assembly structure of this utility model; Figure 6This is a schematic diagram of the top beam assembly structure of this utility model. A wall reinforcement device for a masonry structure house includes: a reinforcement assembly 1, a ground beam assembly 2, and a top beam assembly 3. The reinforcement assembly 1 includes a reinforcement unit 11, with two reinforcement units 11 respectively disposed on both sides of the wall to be reinforced. One end of the reinforcement unit 11 penetrates through the floor slab, and the other end extends to the top of the wall foundation below ground. The ground beam assembly 2 includes ground beam stirrups 21 and ground beam longitudinal bars 22. Two ground beam stirrups 21 are disposed at the ends of the reinforcement units 11 extending to the top of the wall foundation below ground, and are disposed opposite to each other on both sides of the reinforcement unit 11. Multiple ground beam longitudinal bars 22 are connected... The ground beam stirrups 21 and the two ends of the ground beam longitudinal reinforcement 22 are respectively connected to the two ground beam stirrups 21; and the top beam assembly 3 includes top beam stirrups 31 and top beam longitudinal reinforcement 32. The two top beam stirrups 31 are set at one end of the reinforcement unit 11 that penetrates the floor slab. Multiple top beam longitudinal reinforcements 32 are connected to the top beam stirrups 31, and the two ends of the top beam longitudinal reinforcement 32 are respectively connected to the two top beam stirrups 31. By setting the top beam assembly 3, the lower part of the top beam assembly 3 is tightly attached to the top floor slab, ensuring that the prestress is reliably transferred to the wall to be reinforced; wherein, the ground beam assembly 2 and the top beam assembly 3 are filled with concrete.
[0033] Specifically, there are six longitudinal bars 22 in the ground beam, which are arranged in sequence at the upper, middle and lower parts of the left and right ends of the stirrups 21 in the ground beam.
[0034] Specifically, there are six longitudinal bars 32 in the top beam, which are arranged in sequence at the left, middle and right ends of the top beam stirrups 31.
[0035] This masonry structure wall reinforcement device involves setting reinforcement units 11 on both sides of the wall to be reinforced, with one end of the reinforcement unit 11 penetrating the floor slab and the other end extending above the wall foundation below ground. Then, through the cooperation of ground beam stirrups 21 and ground beam longitudinal bars 22, a ground beam assembly 2 is poured above the wall foundation extending below ground by the reinforcement unit 11, and a top beam assembly 3 is poured at the end of the reinforcement unit 11 that penetrates the floor slab. Thus, the reinforcement unit 11 is fixed by the cooperation of the ground beam assembly 2 and the top beam assembly 3. By applying prestress, the seismic resistance of the wall is greatly improved, avoiding the problem of insufficient seismic resistance and safety hazards in old masonry houses.
[0036] This masonry structure wall reinforcement device can significantly improve the seismic performance and overall stability of masonry walls, while also enhancing their energy dissipation performance. It is easy to construct, causes minimal interference with existing structures, and is inexpensive.
[0037] Specifically, when reinforcing the walls of a multi-story building, the reinforcement unit 11 drills holes in the floor slabs so that the reinforcement unit 11 penetrates multiple floors, and the top beam assembly 3 is placed above the top floor.
[0038] The ground beam assembly 2 also includes a ground beam tie bar 23, which is connected to the ground beam longitudinal reinforcement 22. Both ends of the ground beam tie bar 23 are connected to the two opposite ground beam longitudinal reinforcements 22 in the middle of the ground beam stirrups 21, and penetrate through the foundation of the wall to be reinforced. Thus, through the cooperation of the ground beam stirrups 21, the ground beam longitudinal reinforcement 22 and the ground beam tie bar 23, the tensile, bending and shear resistance of the ground beam assembly 2 is enhanced, and the service life of the reinforcement device is improved.
[0039] Specifically, the stirrups 21 and tie bars 23 of the ground beam are C8 steel bars, and the longitudinal bars 22 of the ground beam are C18 steel bars.
[0040] The top beam assembly 3 also includes top beam anchor bars 33, multiple top beam anchor bars 33 are connected to the top beam longitudinal bars 32, and one end of multiple top beam anchor bars 33 extends into the floor slab, thereby improving the stability of the cast top beam assembly 3 and ensuring that the top beam assembly 3 is in close contact with the floor.
[0041] By combining the ground beam assembly 2 and the top beam assembly 3, the reinforcement unit 11 is kept in a straight state and will not be easily deformed by external influences, thereby improving the seismic resistance of the wall.
[0042] The top beam stirrups 31 are C8 steel bars, and the top beam longitudinal bars 32 are C18 steel bars.
[0043] Specifically, the anchor bar 33 of the top beam extends into the floor slab to a depth of two-thirds of the floor slab thickness.
[0044] Reference Figure 2 , Figure 2 This is another structural schematic diagram of the present invention. The wall to be reinforced has opposing grooves on both sides, and the reinforcement unit 11 is set in the groove. The depth and width of the groove are both 10 mm. After the wall reinforcement device is placed, the groove area can be plastered and sealed, thereby restoring the smoothness of the wall surface.
[0045] See 3- Figure 4 , Figure 3 This utility model Figure 1 Schematic diagram of the structure at point A in the middle; Figure 4 This utility model Figure 1 The structural schematic diagram at point B is shown. The reinforcement component 1 also includes anchors 12. Multiple anchors 12 are disposed at the ends of the reinforcement unit 11. There are four anchors 12, which are in close contact with the top surface of the top beam component 3 and the bottom surface of the ground beam component 2, respectively, thereby defining the position of the ground beam component 2 and the top beam component 3 and reinforcing them to further improve their seismic resistance.
[0046] Specifically, the reinforcement unit 11 is a prestressed steel strand with an outer anti-corrosion lubricant and a polyethylene sheath. It can slip relative to the wall and concrete layer, thereby ensuring that it can be in an elastic working state when encountering a severe earthquake and improving the post-earthquake deformation recovery capacity of the entire wall.
[0047] The masonry structure wall reinforcement device in this application is an on-site low- or no-wet operation, which causes minimal changes to the appearance of the original building structure, reduces damage to the interior and exterior decoration, and does not result in a reduction in the building's usable area, low noise, or low dust.
[0048] When reinforcing the wall, first determine the location of the reinforcement unit 11, then chisel grooves in the wall and drill holes in the floor slab to be penetrated. Then, excavate the foundation of the wall to be reinforced on both sides and pour the ground beam assembly 2. Then, pour the top beam assembly 3 on the floor slab and install the reinforcement unit 11 from top to bottom and fix it with anchors 12. Finally, restore the wall surface, floor slab holes, wall foundation, etc., and the whole process is completed.
