Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a foundation reinforcement structure and method for masonry houses. Background Technology

[0002] Masonry is a monolithic material constructed using stone and mortar, or stone and concrete. Stone is readily available locally, making it an economical and widely used construction method in stone-producing areas. In engineering, masonry is primarily used as a load-bearing component, serving as load-bearing walls, columns, and foundations for general residential buildings. However, due to the loose structure, poor integrity, and extremely low shear strength of masonry materials, it is significantly affected by the surrounding geological and hydrological environment. Uneven geological settlement caused by declining groundwater levels can lead to wall cracking. Furthermore, changes in building function or the addition of floors can increase loads, often necessitating reinforcement and modification of the rubble foundation when its shear and compressive strength are insufficient.

[0003] Related technologies, such as Chinese Patent No. CN110206135A, disclose a reinforcement structure for the foundation of a masonry house. The foundation includes walls and a stone base, and comprises anchor bolts, tie bars, foundation beams, and exposed reinforcing bars. The anchor bolts driven into the trenches on both sides of the stone base significantly enhance the bearing capacity of the foundation and increase the stress-bearing area of ​​the stone base. The foundation beams disperse the force transmission path, and the total contact area between the stone base and the ground is increased after reinforcement. The foundation beams and the stone base share the load, greatly reducing the pressure from the walls on the stone base.

[0004] In the aforementioned related technologies, foundation beams are set on both sides of the existing stone foundation, so that the foundation beams can share the load with the stone foundation, thereby indirectly increasing the contact area between the stone masonry building and the foundation, thus achieving a reinforcement effect. However, when using this method, it is necessary to break ground for the foundation outside the building (i.e., outside the stone foundation) and also for the foundation inside the building (i.e., inside the stone foundation), which greatly increases the difficulty. In particular, when construction is carried out inside the building, a large amount of dust will be generated inside the building, and the repair cycle after construction is long. Therefore, it needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a foundation reinforcement structure and method for masonry houses, which prevents the formation of large amounts of dust inside the house and facilitates repair and use of the house after construction.

[0006] Firstly, this application provides a foundation reinforcement structure for masonry houses, which adopts the following technical solution.

[0007] A foundation reinforcement structure for a stone masonry house includes several force transmission rods arranged on the outside of the stone foundation. Each force transmission rod is arranged along the length of the stone foundation. One end of each force transmission rod passes through the stone foundation and is fixedly connected to the stone foundation. The other end of each force transmission rod is fixed in the foundation. The end of each force transmission rod away from the stone foundation is fixedly connected to the foundation by an anchor rod.

[0008] Specifically, by installing dowel bars, some of the pressure of the stone foundation can be transferred to the ground far away from the stone foundation, reducing the pressure per unit area of ​​the original foundation, thereby indirectly achieving the effect of reinforcing the foundation of the masonry house. In addition, the construction of the dowel bars is carried out outdoors, so a lot of dust will not be generated inside the house during the construction process, which makes it easy to repair and use the house after the construction is completed.

[0009] Furthermore, each of the force transmission rods includes several parallel force transmission plates, each of the force transmission plates is vertically arranged, and a connecting seat is installed inside the stone foundation. The connecting seat includes a support plate, a connecting plate, and a viscoelastic rubber sheet. The support plate is horizontally arranged and its top surface is fixed to the stone foundation. Several connecting plates are provided, and the upper side of each connecting plate is fixedly connected to the bottom surface of the support plate. Each force transmission plate and each connecting plate are arranged alternately at intervals. Several viscoelastic rubber sheets are vertically arranged, and the two sides of each viscoelastic rubber sheet are fixedly bonded to any adjacent force transmission plate and connecting plate.

[0010] Specifically, the force transmission rod formed by combining multiple force transmission plates can ensure strength as much as possible while reducing material consumption. The connecting seat composed of support plate, connecting plate and viscoelastic rubber sheet can realize the elastic connection between the force transmission rod and the connecting seat, making the two less susceptible to vibration.

[0011] Furthermore, each of the aforementioned force transmission rods is inserted into the stone foundation, and the width of each of the aforementioned viscoelastic rubber sheets is smaller than the width of the force transmission rod. A sealing strip extending along the length of the force transmission rod is filled between the upper sides of any two adjacent force transmission plates. The two adjacent force transmission plates and the sealing strip enclose a drainage channel with an opening on the lower side. The end of each drainage channel located outside the stone foundation is connected to the inlet of an external water pump.

[0012] Specifically, by utilizing the combination of an external water pump and a drainage channel, a forced vacuum drainage can be achieved in the foundation through a dowel bar, which can further reinforce the soil foundation.

[0013] Furthermore, it also includes a reinforcing plate, which is fixed to the outer wall of the stone foundation using wall nails. Each of the force transmission rods passes through the reinforcing plate and is welded to the reinforcing plate.

[0014] Specifically, by using a reinforcing plate, the dowel bar can be indirectly fixed to the outer wall of the stone foundation, further improving the connection strength between the dowel bar and the stone foundation.

[0015] Furthermore, a balance platform is connected to the end of each force transmission rod away from the stone foundation. The balance platform includes several parallel balance plates, each of which is vertically arranged. The lower side of each balance plate is cross-connected to the upper side of each force transmission rod. Structural adhesive is filled between any two adjacent balance plates. The upper ends of the anchor rods used to fix the force transmission rods are fixedly connected to the balance platform.

[0016] Specifically, the balancing platform composed of balancing plates can increase the number of anchor bolt installation points. At the same time, it can connect the forces of each force transmission rod in parallel, improving the stability and balance of the forces on each force transmission rod.

[0017] Secondly, the construction method for the foundation reinforcement structure of masonry houses provided in this application adopts the following technical solution:

[0018] A construction method for reinforcing the foundation of a masonry house, as described above, includes the following steps:

[0019] S1. Clear the foundation around the stone foundation to form a foundation pit, and remove debris after leveling.

[0020] S2. Carve out several mounting holes on the stone base, and then install the connecting seat in each mounting hole;

[0021] S3. Install each force transmission rod in the foundation pit, and fix one end of each force transmission rod to the respective connecting seat.

[0022] S4. Use a balance platform to fix the other end of each force transmission rod, and use anchor bolts to fix the balance platform in the foundation pit.

[0023] S5. Backfill the foundation with plain soil and compact the backfill soil thoroughly.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Construction can be carried out only outside the house, without the need for breaking ground inside the house, effectively avoiding dust generated inside the house due to construction.

[0026] 2. After construction, the dowel bar can not only provide support and reinforcement using leverage, but also perform forced drainage to improve the stability of the foundation. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0035] A foundation reinforcement structure for masonry houses, referring to Figure 1 The system includes a force transmission rod assembly 2 and a balance platform 3. The balance platform 3 is located on the outside of the stone foundation 1, with its lower side buried in the foundation and its upper side extending out of the foundation as a reference point. The force transmission rod assembly 2 includes several force transmission rods 2 arranged along the length of the stone foundation 1. One end of each force transmission rod 2 is fixedly connected to the stone foundation 1, and the other end of each force transmission rod 2 is fixedly connected to the balance platform 3. Among them, sleepers 4 are buried in the foundation directly below each force transmission rod 2. Each sleeper 4 is arranged along the length of the force transmission rod 2, and each force transmission rod 2 is laid on the sleeper 4.

[0036] Reference Figure 1 and Figure 2Each dowel bar 2 includes a dowel plate 21 and a sealing strip 22. Several dowel plates 21 and sealing strips 22 are provided and are arranged alternately. Each dowel plate 21 is vertically arranged. Both sides of each sealing strip 22 are fixedly connected to the upper sides of any two adjacent dowel plates 21. A drainage channel 23 is formed between any two adjacent dowel plates 21, and one end of each drainage channel 23 located outside the stone foundation 1 is connected to the inlet of an external water pump. When the dowel bar 2 is connected to the stone foundation 1, it passes through the stone foundation 1 and extends below the ground level of the masonry building, allowing the groundwater of the masonry building to be forcibly discharged via an external water pump.

[0037] It should be noted that the thickness of the sealing strip 22 is greater than the thickness of the force transmission plate 21, and the width of the sealing strip 22 is greater than half the width of the force transmission plate 21.

[0038] Reference Figure 1 , Figure 3 and Figure 4 Several connecting seats 5 are installed inside the stone foundation 1. The portion of each force transmission rod 2 located inside the stone foundation 1 is connected to each connecting seat 5. Each connecting seat 5 includes a reinforcing plate 51, a supporting plate 52, a connecting plate 53, and a viscoelastic rubber sheet 54. The reinforcing plate 51 is fixed to the outer wall of the stone foundation 1 using wall nails. The supporting plate 52 is buried in the stone foundation 1, and its top surface is fixed to the stone foundation 1. Several connecting plates 53 are provided. One side of the supporting plate 52 and each connecting plate 53 is fixedly connected to the side of the reinforcing plate 51 that is in contact with the surface of the stone foundation 1. The force transmission rods 2 all pass through the reinforcing plate 51. Each force transmission plate 21 and each connecting plate 53 are arranged alternately. Several viscoelastic rubber sheets 54 are vertically arranged, and the two sides of each viscoelastic rubber sheet 54 are fixedly bonded to any adjacent force transmission plate 21 and connecting plate 53.

[0039] It should be noted that one end of each sealing strip 22 extends to the end of each force transmission plate 21 away from the stone foundation 1, and the other end of each sealing strip 22 is set close to the outer wall of the stone foundation 1 so that the sealing strip 22 can avoid the connecting seat 5; when the connecting seat 5 is connected to the force transmission rod 2, a gap is reserved between the lower side of the connecting seat 5 and the bottom surface of the force transmission rod 2 to allow water to drain.

[0040] Reference Figure 5The balance platform 3 includes balance plates 31 and structural adhesive 32. Several balance plates 31 are arranged parallel to each other and are vertically arranged. The lower side of each balance plate 31 is cross-connected with the upper side of each force transmission rod 2. The structural adhesive 32 is filled between any two adjacent balance plates 31 so that the upper ends of the anchor rods used to fix the force transmission rods 2 are fixedly connected to the balance platform 3. The anchor rods used to anchor the balance platform 3 pass through the structural adhesive 32 to avoid damaging the balance plates 31. The balance plates 31 are made of high-strength metal plates.

[0041] How this application works:

[0042] By setting up a balance platform 3 and a force transmission rod 2, the leverage force can be used to transfer part of the pressure on the stone foundation 1 to the foundation away from the stone foundation 1, reducing the pressure per unit area of ​​the original foundation, thereby indirectly achieving the effect of reinforcing the foundation of the masonry house. Furthermore, the construction of the balance platform 3 and the force transmission rod 2 are carried out outdoors, so a large amount of dust will not be generated inside the house during the construction process, making it convenient for the house to be repaired and used after the construction is completed.

[0043] This application also discloses a construction method for reinforcing the foundation of a masonry house as described above, comprising the following steps:

[0044] S1. Clear the foundation around the stone foundation to form a foundation pit, and remove debris after leveling.

[0045] S2. Carve out several installation holes on the stone base, and then install the connecting seat 5 in each installation hole;

[0046] S3. Install each force transmission rod 2 in the foundation pit, and fix one end of each force transmission rod 2 to each connecting seat 5 respectively.

[0047] S4. Use the balance platform 3 to fix the other end of each force transmission rod 2, and use anchor rods to fix the balance platform 3 in the foundation pit.

[0048] S5. Backfill the foundation with plain soil and compact the backfill soil thoroughly.
