Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology for basement structures, and in particular to a waterproof and leak-proof structure for basement connection nodes. Background Technology

[0002] A basement is a room or space located below ground level in a building. It is usually used for storage, parking, equipment installation, or as a special function area (such as a refuge, underground shopping mall, etc.). As an important part of the building structure, the waterproofing performance of the wall joints of the basement directly affects the building's safety and service life.

[0003] Traditional waterproofing at basement connection joints has the following drawbacks: single-layer waterproofing or permanent fixed installations are insufficient to prevent complex seepage paths, making it easy for groundwater to penetrate through tiny cracks in the joints or areas where the waterproofing layer has peeled off. Furthermore, disassembly and maintenance require damage to the wall structure, increasing the complexity and cost of the repair process. Additionally, rigid waterproofing components (such as waterstop steel plates) lack sufficient coordination with wall deformation, making them prone to cracking and failure due to foundation settlement or temperature changes. Therefore, we propose a waterproofing and seepage-proof structure for basement connection joints to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies, such as the difficulty in preventing complex water seepage paths and the inconvenience of disassembly and maintenance, which increases maintenance costs, as well as the lack of coordination between rigid components and wall deformation, which leads to easy cracking of the waterproof layer. Therefore, this utility model proposes a waterproof and seepage-proof structure for basement connection nodes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waterproof and seepage-proof structure for basement connection nodes includes an existing wall and a newly constructed wall. Installation grooves are provided at the connection points of the existing and newly constructed walls, and two interconnected installation grooves form a waterproof groove. An inner waterproof layer and a water-stop steel plate are sequentially laid on the inner wall of the waterproof groove from the inside out. Installation plates are detachably and fixedly connected to the existing and newly constructed walls via fixing components. An extrusion plate is threadedly connected to one side of the installation plate, extending into the waterproof groove and fitting against the concave surface of the water-stop steel plate.

[0007] In one possible design, the inner waterproof layer includes a first waterproof strip and a second waterproof strip stacked together, and the water-stop steel plate is bonded to the outer side of the second waterproof strip to form a rigid waterproof layer.

[0008] In one possible design, the fixing component includes a fixing rod pre-embedded in the existing wall and the newly built wall, the mounting plate is provided with mounting holes corresponding to the fixing rod, and the fixing rod passes through the mounting hole and is locked by a fixing nut.

[0009] In one possible design, the existing wall and the new wall are provided with fixing grooves, the second waterproof strip extends into the fixing grooves, and the mounting plate is provided with fixing blocks that fit into the fixing grooves.

[0010] In one possible design, the fitting gap between the fixing block and the fixing groove is 1-3mm, and the outer surface of the fixing block is provided with anti-slip texture that fits with the second waterproof strip.

[0011] In one possible design, a flexible roll material is fixedly bonded to the outside of the mounting plate, and the flexible roll material covers the gap between the mounting plate and the existing wall or the newly built wall.

[0012] In one possible design, the flexible roll has an elongation of not less than 200%, and its contact surface with the wall is provided with a pressure-sensitive adhesive layer.

[0013] In one possible design, the contact surface of the extrusion plate is provided with a raised structure that matches the concave surface of the waterstop steel plate, and the radius of curvature of the raised structure is 0.5-1mm smaller than that of the concave surface of the waterstop steel plate.

[0014] In one possible design, a sealing strip is provided between the mounting plate and the existing wall and the newly built wall, and the sealing strip is respectively attached to the side of the mounting plate and the existing wall and the newly built wall that are close to each other.

[0015] In this application, during construction, an installation groove is first opened at the connection between the existing wall and the newly built wall, so that the two installation grooves are connected to form a waterproof groove, providing space for the subsequent installation of waterproof components. Then, an inner waterproof layer is laid from the inside to the outside on the inner wall of the waterproof groove. The inner waterproof layer includes a first waterproof strip and a second waterproof strip, forming a double-layer waterproof barrier. Even if one layer is damaged, the other layer can still be waterproofed independently, achieving multi-level blocking of the seepage path. Then, a water-stop steel plate is installed on the outside of the inner waterproof layer in the waterproof groove, so that it is attached to the outside of the second waterproof strip, resisting the impact of groundwater pressure through rigid constraint.

[0016] Then, the mounting plate is detachably fixed to the existing wall and the new wall using the fixing component. The fixing rod of the fixing component is pre-fixed to one side of the wall. The mounting holes on the mounting plate correspond to the fixing rod. After insertion, the fixing nut is threaded to connect, which realizes the quick installation and removal of the mounting plate without damaging the wall, shortening the maintenance cycle and reducing costs. At the same time, a sealing strip is set between the mounting plate and the wall to fill the gap between the two to enhance the sealing effect and prevent water penetration.

[0017] Meanwhile, a fixing block is fixed on the side of the mounting plate closest to the wall, and a corresponding fixing groove is opened on the wall. The second waterproof strip extends into the fixing groove, and the fixing block is inserted into the fixing groove and fits against the outside of the second waterproof strip to limit the displacement of the second waterproof strip and ensure the stability of the waterproof structure. On one side of the mounting plate, between the two fixing blocks, a pressing plate is connected by a thread to fit against the concave surface of the waterstop steel plate, further fixing the waterstop steel plate and enhancing the reliability of the waterproofing.

[0018] Finally, a flexible roll material is fixedly bonded to one side of the mounting plate to cover the gap between the mounting plate and the wall. The elastic deformation of the flexible roll material absorbs the displacement caused by wall settlement or temperature deformation, preventing the waterproof layer from cracking. In this way, the components work together to form a complete waterproof joint structure, effectively solving the waterproofing problem at the joints of traditional basements, and achieving the effects of high-efficiency waterproofing, easy maintenance and adaptability to wall deformation.

[0019] Beneficial effects: In this utility model, the waterproof and seepage-proof structure for basement connection nodes forms a double-layer waterproof barrier through the first and second waterproof strips of the inner waterproof layer to achieve multi-level blocking of the seepage path. Even if a single waterproof strip is damaged, the second layer can still function independently. With the rigid constraint of the water-stop steel plate and the extrusion plate, it effectively resists the impact of groundwater pressure and significantly reduces the joint leakage rate.

[0020] In this utility model, the waterproof and seepage-proof structure for basement connection nodes, through the threaded connection of the fixing components and the snap-fit ​​structure of the mounting plate, allows the waterproof structure to be quickly disassembled without damaging the wall, greatly shortening the maintenance cycle and reducing the cost of secondary construction.

[0021] In this utility model, the waterproof and seepage-proof structure for basement connection nodes can absorb the displacement caused by wall settlement or temperature deformation through the elastic deformation capability of flexible roll material and sealing strip, avoiding cracking of the waterproof layer due to stress concentration. The interlocking design of fixing block and fixing groove further restricts the displacement of waterproof strip, ensuring the long-term stability of waterproof structure under dynamic load.

[0022] In this invention, a multi-level barrier is formed by the inner waterproof layer and the water-stop steel plate to block water seepage paths, which can effectively resist groundwater pressure even if a single layer is damaged; the use of threaded connection and snap-fit ​​structure enables quick assembly and disassembly, avoids damage to the wall, and significantly reduces maintenance costs; the flexible roll material and sealing strip absorb structural deformation and displacement, and the fixed block interlocking design restricts the displacement of the waterproof strip, ensuring long-term stability under dynamic loads, and comprehensively solving the technical problems of cracking, difficult maintenance and poor adaptability of traditional waterproof layers.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1: Refer to Figure 1-4 A waterproof connection structure includes an existing wall 1 and a newly constructed wall 2, with an installation groove 3 formed at the connection point between the existing wall 1 and the newly constructed wall 2. Specifically, installation grooves 3 are formed on both the existing wall 1 and the newly constructed wall 2 at their junction, and the two installation grooves 3 must be interconnected to form a waterproof groove. This waterproof groove provides the necessary space for the installation of subsequent waterproof components, and its dimensions must be precisely designed according to the specifications of the subsequent waterproof components to ensure that each component can be installed properly.

[0030] After the installation groove 3 is opened, the inner waterproof layer 5 is laid sequentially from the inside to the outside on the inner wall of the waterproof groove. The inner waterproof layer 5 includes a first waterproof strip 501 and a second waterproof strip 502, wherein the first waterproof strip 501 forms the first waterproof barrier and the second waterproof strip 502 forms the second waterproof barrier. During laying, the first waterproof strip 501 is first tightly attached to the inner wall of the waterproof groove to ensure no wrinkles or air bubbles, so as to ensure its waterproof effect; then the second waterproof strip 502 is laid on the outside of the first waterproof strip 501, and it is also necessary to ensure that it is laid tightly. The two layers of waterproof strips form a double-layer waterproof barrier. Even if one layer is damaged, the other layer can still play a waterproof role independently, realizing multi-level blocking of water seepage paths.

[0031] After the inner waterproof layer 5 is laid, a water-stop steel plate 6 is installed on the outside of the inner waterproof layer 5 within the waterproof groove. The water-stop steel plate 6 must be in close contact with the outside of the second waterproof strip 502, using its own rigid structure to resist the impact of groundwater pressure. During installation, ensure that the water-stop steel plate 6 is accurately positioned and in close contact with the second waterproof strip 502, avoiding gaps, so as to fully exert its rigid restraint effect.

[0032] Next, the mounting plate 8 is detachably fixed to the existing wall 1 and the newly constructed wall 2 using a fixing assembly. The fixing assembly includes multiple fixing rods 9 fixed to one side of the existing wall 1 and the newly constructed wall 2. All fixing rods 9 are threaded and located on the same side of the mounting groove 3. Multiple mounting holes corresponding to the fixing rods 9 are provided on the mounting plate 8. During installation, the fixing rods 9 are inserted into the corresponding mounting holes, and then the fixing nuts are connected by threads, enabling quick assembly and disassembly of the mounting plate 8. This fixing method does not require damage to the wall, shortening the maintenance cycle and reducing costs during subsequent repairs. Simultaneously, a sealing strip 12 is installed between the mounting plate 8 and the existing wall 1 and the newly constructed wall 2. The sealing strip 12 fills the gap between them, enhancing the sealing effect and effectively preventing water penetration.

[0033] In addition, a fixing groove 4 is provided on one side of both the existing wall 1 and the newly built wall 2, and the second waterproof strip 502 extends into the corresponding fixing groove 4. Two fixing blocks 11 corresponding to the fixing groove 4 are fixedly installed on the side of the mounting plate 8 near the existing wall 1 and the newly built wall 2. One side of each fixing block 11 extends into the corresponding fixing groove 4 and abuts against the outer side of the second waterproof strip 502. The cooperation between the fixing blocks 11 and the fixing groove 4 restricts the displacement of the second waterproof strip 502, ensuring the stability of the waterproof structure.

[0034] This application can be used in the field of waterproofing technology for underground structures, as well as in other fields applicable to this application.

[0035] Example 2: Reference Figure 1-3 An improvement upon Embodiment 1: A waterproof and seepage-proof structure for basement connection nodes, applied in the field of basement structure waterproofing technology, is provided. On one side of the mounting plate 8, between two fixing blocks 11, a compression plate 10 is detachably connected via threads. The compression plate 10 matches the concave surface of the water-stop steel plate 6. During installation, the compression plate 10 is threaded onto the mounting plate 8, extending one side into the waterproof groove and fitting against the concave surface of the water-stop steel plate 6, further securing the water-stop steel plate 6 and enhancing the reliability of waterproofing.

[0036] Finally, the flexible roll material 7 is fixedly bonded to one side of the mounting plate 8, with the extrusion plate 10 positioned between the mounting plate 8 and the extrusion plate 10. One side of the flexible roll material 7 is respectively attached to one side of the existing wall 1 and the newly built wall 2, covering the gap between the mounting plate 8 and the existing wall 1 and the newly built wall 2. Through its own elastic deformation, the flexible roll material 7 can absorb the displacement caused by wall settlement or temperature deformation, preventing the waterproof layer from cracking, thereby ensuring the waterproof effect of the entire waterproof joint structure.

The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
