Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a waterproof and anti-buoyancy structure device for underground buildings. Background Technology

[0002] Underground buildings refer to building structures that are wholly or partially built underground, utilizing underground space to meet various functional needs, such as subway stations, underground parking lots, underground shopping malls, pedestrian streets, underground libraries, etc. However, when encountering floods, rainstorms, or other weather conditions, underground buildings, being buried below ground level, are inevitably affected by the buoyancy of groundwater. Therefore, waterproof and anti-buoyancy structures are needed to support the bottom of underground buildings to prevent them from floating.

[0003] In existing technologies, conventional anti-buoyancy structures are simply single load-bearing columns that increase the weight of the building to prevent it from floating upwards when encountering large amounts of water. However, a single load-bearing column can only provide anti-buoyancy within a certain range of buoyancy and cannot provide anti-buoyancy when the buoyancy is too large, resulting in poor anti-buoyancy performance of underground buildings. Utility Model Content

[0004] In view of this, the present invention provides a waterproof and anti-buoyancy structure device for underground buildings. The main technical problem to be solved is that the existing technology achieves the anti-buoyancy effect by adding a load-bearing column structure at the bottom of the underground building, but it cannot play a better anti-buoyancy role when the buoyancy is too large.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a waterproof and anti-buoyancy structure device for underground buildings, comprising a building, a waterproof layer fixedly connected to the outer wall of the building, an anti-buoyancy component installed inside the building and the waterproof layer, the anti-buoyancy component comprising an anchor rod, reinforcing bars, and a support plate, a fixing rod fixedly connected inside the waterproof layer, the anchor rod fixedly connected inside the fixing rod, the anchor rod fixedly connected inside the building, a cone block fixedly connected to the lower surface of the anchor rod, multiple reinforcing bars provided, the multiple reinforcing bars fixedly connected inside the support plate, the outer wall of the support plate fitting against the inner wall of the fixing rod, a sealing cover slidably connected to the top of the anchor rod, an installation plate installed above the sealing cover, an installation groove opened inside the building, the installation plate placed inside the installation groove, a bolt threadedly connected inside the installation plate, the bolt threadedly connected inside the building.

[0006] By adopting the above technical solution, a waterproof layer is fixed to the outer wall of the building to achieve a waterproof effect. The fixing rod is fixed inside the waterproof layer, and the anchor rod is fixed inside the fixing rod and penetrates through the building and the waterproof layer. The cone block is fixed underground. Multiple support plates are fixed to the outer wall of the steel bar, and the steel bar and support plates are placed inside the fixing rod. Then, a sealing cap is placed on the top of the anchor rod to achieve a sealing effect and prevent water and dust from entering. After the mounting plate is placed inside the mounting groove, the mounting plate is fixed inside the mounting groove with bolts. When encountering a large flood or rainfall, the water level rises and the building may float. By using the anchor rod, steel bar, support plate, fixing rod, sealing cap, and mounting plate in combination, the building is prevented from floating, achieving an anti-buoyancy effect.

[0007] As a further description of the above technical solution: a water pipe is fixedly connected inside the fixing rod, the water pipe is fixedly connected inside the building and the waterproof layer, a sleeve is fixedly connected to the end of the water pipe away from the fixing rod, the sleeve is fixedly connected inside the waterproof layer, and a regulating valve is fixedly connected to the outer wall of the sleeve.

[0008] By adopting the above technical solution, when the bottom water level is too high and spreads, affecting the building and causing it to float, the regulating valve is opened. The water at the bottom enters through the bottom end of the water pipe and is discharged through the sleeve and regulating valve. The drainage helps to prevent the building from floating.

[0009] As a further description of the above technical solution: multiple support plates are provided, and the multiple support plates are evenly distributed on the outer wall of the reinforcing bars. A limit hole is opened inside the support plate, and multiple limit holes are provided.

[0010] By adopting the above technical solution, multiple limiting holes are opened inside the support plate to limit the movement of the reinforcing bars and prevent them from shifting.

[0011] As a further description of the above technical solution: the number of the limiting holes is the same as the number of the reinforcing bars, and the reinforcing bars are fixedly connected inside the limiting holes.

[0012] By adopting the above technical solution, the support plate is adapted and fixed to the outer wall of the steel bar by opening multiple limiting holes of the same number as the steel bar.

[0013] As a further description of the above technical solution: the sealing cover has two limiting holes inside, the number of the two limiting holes being the same as the number of the reinforcing bars, and the reinforcing bars are slidably connected inside the two limiting holes.

[0014] By adopting the above technical solution, multiple limiting holes are opened inside the sealing cover, the same number as the number of reinforcing bars. The sealing cover can also limit the movement of the reinforcing bars when sealing the top of the anchor rod.

[0015] As a further description of the above technical solution: the mounting plate has a plurality of limiting holes 3 inside, the number of limiting holes 3 being the same as the number of reinforcing bars, and the reinforcing bars are slidably connected inside the limiting holes 3.

[0016] By adopting the above technical solution, multiple limiting holes, the same number as the number of reinforcing bars, are opened inside the mounting plate, which can limit the reinforcing bars while the mounting plate is fixed.

Multiple load-bearing columns are provided, and the multiple load-bearing columns are evenly distributed on the lower surface of the waterproof layer.

[0018] By adopting the above technical solution, multiple load-bearing columns are fixed at the bottom of the waterproof layer, thereby increasing the gravity of the waterproof layer and the bottom of the building. The cone-shaped blocks fixed at the bottom of the load-bearing columns are easy to insert and fix.

[0019] By employing the above technical solution, the waterproof and anti-buoyancy structural device for underground buildings of this utility model has at least the following beneficial effects:

[0020] 1. Compared with existing technologies, this waterproof and anti-buoyancy structure device for underground buildings, by fixing a fixing rod inside the waterproof layer, fixing an anchor rod inside the fixing rod, and fixing the cone block and the bottom end of the anchor rod underground, fixing multiple support plates to the outer wall of multiple steel bars, and fixing the steel bars and support plates inside the anchor rod for support, placing a sealing cap at the top of the anchor rod to seal the top of the anchor rod and limit the steel bars, fixing the building inside the waterproof layer and placing it on the outer wall of the anchor rod, steel bars, and sealing cap, and then fixing an installation plate above the sealing cap and fixing it to the installation groove opened inside the building. By fixing the fixing rod, anchor rod, and steel bars inside the ground, a tensile force is generated on the building and the waterproof layer to prevent the building and the waterproof layer from floating when exposed to water.

[0021] 2. Compared with existing technologies, this waterproof and anti-buoyancy structure device for underground buildings fixes water pipes inside fixed rods and to the building and waterproof layer. A sleeve and regulating valve are fixed on the outer wall of the water pipes, with the regulating valve located on the outer wall of the waterproof layer. When there is too much water, water can enter the sleeve through the water pipes. Adjusting the regulating valve can drain water and assist in anti-buoyancy of the building and waterproof layer. Multiple load-bearing columns and cone blocks are fixed at the bottom of the waterproof layer to increase the weight of the building and waterproof layer and improve the anti-buoyancy effect.

[0028] Reference Figure 1-4This utility model provides a waterproof and anti-buoyancy structure device for underground buildings: It includes a building 1, with a waterproof layer 2 fixedly connected to the outer wall of the building 1. The waterproof layer 2 provides waterproofing to the exterior of the building 1, preventing water from entering the interior of the building 1. An anti-buoyancy component is installed inside the building 1 and the waterproof layer 2. The anti-buoyancy component includes anchor rods 4, reinforcing bars 5, and a support plate 6. A fixing rod 3 is fixedly connected inside the waterproof layer 2, with its bottom fixed underground. An anchor rod 4 is fixedly connected inside the fixing rod 3 and inside the building 1. A cone block 401 is fixedly connected to the lower surface of the anchor rod 4, with the bottoms of both the anchor rod 4 and the cone block 401 fixed underground. Multiple reinforcing bars 5 are provided and fixedly connected inside the support plate 6. The outer wall of the support plate 6 is in contact with the inner wall of the fixing rod 3. A sealing cap 7 is slidably connected to the top of the anchor rod 4, with the sealing cap 7 covering the upper end of the anchor rod 4. A sealing cover 7 is sealed, and an installation plate 8 is installed above it. The installation plate 8 is positioned above the sealing cover 7 to limit and fix the anchor rod 4 to the building 1, the waterproof layer 2, and the underground interior. An installation groove 101 is opened inside the building 1, and the installation plate 8 is placed inside the installation groove 101. The installation plate 8 is positioned inside the installation groove 101 so that it is flush with the surface of the building 1 and does not affect the use of the building 1. The installation plate 8 is threaded with a bolt 9, which is threaded inside the building 1. A water pipe 10 is fixedly connected inside the fixing rod 3. The water pipe 10 is fixedly connected inside the building 1 and the waterproof layer 2. A sleeve 11 is fixedly connected to the end of the water pipe 10 away from the fixing rod 3. The sleeve 11 is fixedly connected inside the waterproof layer 2. A regulating valve 12 is fixedly connected to the outer wall of the sleeve 11. The connection between the water pipe 10, the sleeve 11, and the regulating valve 12 facilitates drainage and helps to achieve an anti-buoyancy effect.

[0029] Multiple support plates 6 are evenly distributed on the outer wall of the reinforcing bars 5. Each support plate 6 has multiple limiting holes 601, the number of which is the same as the number of reinforcing bars 5. These limiting holes 601 limit the reinforcing bars 5 to prevent displacement. The reinforcing bars 5 are fixedly connected inside the limiting holes 601. Similarly, the sealing cover 7 has multiple limiting holes 701, the number of which is the same as the number of reinforcing bars 5. These limiting holes 701 also limit the reinforcing bars 5, and the reinforcing bars 5 are slidably connected to the limiting holes 701. Inside the 01, the mounting plate 8 has multiple limiting holes 801. The number of limiting holes 801 is the same as the number of reinforcing bars 5. The reinforcing bars 5 are slidably connected inside the limiting holes 801. The limiting holes 801 limit the reinforcing bars 5. The lower surface of the waterproof layer 2 is fixedly connected to a load-bearing column 13. The bottom of the load-bearing column 13 is fixedly connected to a cone block 14. Multiple load-bearing columns 13 are provided and are evenly distributed on the lower surface of the waterproof layer 2. The load-bearing columns 13 and the cone block 14 play a role in reinforcing the waterproof layer 2 and the building 1, and help to achieve the anti-buoyancy effect.

[0030] Working Principle: When excessive water volume causes the water level to rise, potentially causing the waterproof layer 2 and building 1 to float, the load-bearing column 13 and cone block 14, fixed underground, exert tension on the waterproof layer 2 and building 1, providing a simple anti-buoyancy effect. Simultaneously, the waterproof layer 2 is internally fixed with a fixing rod 3, the bottom of which is also underground. Anchor rods 4 are fixed inside the fixing rods 3, and steel bars 5 and support plates 6 are fixed inside the anchor rods 4. Anchor rods 4 and cone block 401 are also placed underground. Through the fixing rods 3, anchor rods 4, and steel bars 5, the bottom of building 1 and waterproof layer 2 are supported, and combined with the load-bearing column 13 and cone block 14, a greater tension is generated, thereby improving the anti-buoyancy effect of building 1 and waterproof layer 2. Furthermore, when the water level is too high and spreads... When the regulating valve 12 is opened, water is discharged through the water pipe 10, the sleeve 11, and the regulating valve 12. The drainage method helps to prevent the building 1 and the waterproof layer 2 from floating. The sealing cover 7 seals the upper end of the anchor rod 4 and can limit the position of the reinforcing bar 5. The mounting plate 8 is installed on the upper surface of the sealing cover 7 and limits the position of the sealing cover 7 to prevent the fixed rod 3, anchor rod 4, sealing cover 7 and other structures from moving upward and affecting the anti-floating effect. The mounting plate 8 is placed inside the mounting groove 101 and is flush with the mounting groove 101, which does not affect the use of the building 1. The excess part of the reinforcing bar 5 extending beyond the upper end of the mounting plate 8 can be cut so that the top of the reinforcing bar 5 is also flush with the mounting plate 8, which will not affect the normal use of the building 1 and ensure the safety of the building 1 during use.
