Description

Technical Field

[0001] This application belongs to the field of building technology, and in particular relates to an anchor structure for anti-buoyancy in basement structures. Background Technology

[0002] In basement structural engineering, groundwater buoyancy is one of the key factors affecting structural stability. To resist the uplift effect of groundwater on the basement floor slab and ensure the vertical load-bearing stability of the structure, anti-buoyancy anchors have become widely used components. These components need to penetrate vertically through the basement base layer, waterproofing layer, and basement floor slab, and be fixedly connected to the base layer. Their penetration characteristic inevitably creates annular penetration gaps between the anchor and each structural layer.

[0003] However, existing anti-buoyancy anchor structures face significant leakage problems in practical applications. The materials of the anti-buoyancy anchor, the basement, the waterproof layer, and the basement floor slab are significantly different, with different coefficients of thermal expansion and contraction. During long-term use, structural deformation can easily lead to the expansion of the penetration gap or the formation of secondary gaps. Traditional sealing methods often use a single filling material, which is difficult to adapt to deformation requirements and can create channels for groundwater seepage. Furthermore, the traditional waterproof layer lacks targeted reinforcement design at the anchor penetration points. The joints between the waterproof coating and the waterproof membrane, as well as the bonding areas between the waterproof layer and the anchor surface, are prone to damage and lifting, compromising the waterproof system. Improvements are needed in these areas. Utility Model Content

[0004] The purpose of this application is to provide an anchor structure for anti-buoyancy in basement structures, which can solve the above-mentioned problems.

[0005] The purpose of this application is to provide an anchor structure for anti-buoyancy in basement structures, comprising: The base layer is topped with a waterproof layer and a basement floor slab. The anchor rod body is installed vertically through the base layer, waterproof layer and basement floor slab, and is fixedly connected to the base layer; The integrated waterproof structure includes a continuous waterproof coating applied to the surface of the anchor body, a sealed waterproof sleeve fitted on the outside of the anchor body, an expansion waterstop embedded in the waterproof sleeve, and a waterstop plate fixed to the upper part of the anchor body. The waterstop plate is flush with and sealed to the upper surface of the basement floor slab. The gaps between the anchor bolt body and the waterproof layer and the basement floor slab are filled and sealed by a waterproof coating and a sealing waterproof sleeve.

[0006] The above-mentioned anchor structure for anti-buoyancy of basement structure is adopted. The main body of the anchor penetrates the base layer, waterproof layer and basement floor slab in the vertical direction and is fixed to the base layer. It not only achieves effective anti-buoyancy support for basement structure, resists the lifting effect of groundwater buoyancy on the floor slab and ensures the vertical stability of the structure, but also forms all-round sealing protection through integrated waterproof structure.

[0007] A continuous waterproof coating acts directly on the anchor bolt surface, forming the first waterproof barrier. This blocks the seepage path of groundwater along the anchor bolt surface and between the anchor bolt and each structural layer. The sealing waterproof sleeve fills the gaps between the anchor bolt and each layer, preventing these gaps from becoming seepage channels and achieving a combination of gap sealing and anchor bolt fixation. The waterstop plate is flush with the upper surface of the basement floor slab, sealing any potential leakage gaps from the top of the structure and further preventing surface water infiltration. By integrating the anti-buoyancy load-bearing function with the waterproof sealing function, the leakage problems caused by incomplete sealing at the penetration points between traditional anti-buoyancy anchor bolts and structural layers, and the disconnect between anti-buoyancy and waterproof functions, are solved, thus achieving a dual guarantee of anti-buoyancy stability and waterproof reliability.

[0008] Furthermore: the expansion waterstop is wound around the anchor rod body in the circumferential direction, and the space between adjacent winding sections of the expansion waterstop is filled with a sealing medium.

[0009] The expansion sealant is wound around the anchor bolt circumferentially, effectively increasing the contact area with the anchor bolt surface and forming a continuous annular sealing barrier, thus enhancing the sealing effect on the through gaps. The sealing medium filling the gaps between adjacent winding sections fills the tiny gaps at the joints of the sealant, preventing water from seeping in through the joints.

[0010] The expansion waterstop is a putty-type expansion waterstop. The sealing medium can be asphalt caulking material or oil-based sealing medium. Because the expansion waterstop itself has the property of expanding when it comes into contact with water, it forms a double protection effect when combined with the filling and sealing effect of the sealing medium: when a small amount of water seeps into the waterstop area, the waterstop expands after contact with water and further squeezes the gap, enhancing the sealing effect; the sealing medium improves the sealing and structural integrity of the joint, preventing gaps from appearing at the joint due to stress or deformation, thus solving the problem of loose waterstop joints and easy formation of leakage channels.

[0011] Furthermore, the continuous waterproof coating covers the entire area where the anchor body penetrates the base layer, the waterproof layer, and the basement floor slab, and the waterproof coating extends to the outside of the penetration section below the bottom of the base layer and above the waterproof layer.

[0012] A continuous waterproof coating covers the entire area of ​​the anchor bolt that penetrates each structural layer, creating a seamless surface seal that blocks the seepage path of groundwater between the anchor bolt surface and the basement, waterproof layer, and basement floor slab. The coating extends below the bottom of the basement, intercepting deep underground seepage and reducing the risk of water seeping upwards along the anchor bolt root. Extending to the outside of the penetration section above the waterproof layer, it provides additional sealing protection at the connection between the anchor bolt and the upper part of the basement floor slab, thus compensating for weak points in the seal above the penetration area.

[0013] Meanwhile, the continuous, uninterrupted coating design avoids the sealing gaps that occur due to insufficient coverage in traditional waterproof coatings. At the same time, the coating is tightly bonded to the surface of the anchor bolt, forming a strong protective layer that can protect against groundwater erosion and reduce damage to the anchor bolt from the external environment, thus extending the service life of the anchor bolt.

[0014] Furthermore, the waterproof layer comprises, from bottom to top, the following: Coating reinforcement layer; Waterproof coating layer; Waterproof membrane layer; The coating reinforcement layer is bonded to the base surface, the waterproof membrane layer is tightly bonded to the outer wall of the sealed waterproof sleeve, and a covering waterproof protective layer is provided on top of the waterproof membrane layer.

[0015] The coating reinforcement layer adheres tightly to the substrate surface, effectively enhancing the adhesion between the subsequent waterproof coating layer and the substrate, preventing waterproofing failure due to peeling of the waterproof coating layer from the substrate. The waterproof coating layer and the waterproof membrane layer form a composite waterproofing structure, with the two waterproofing materials complementing each other: the waterproof coating layer fills tiny pores and cracks on the substrate surface; the waterproof membrane layer forms a large-area continuous protective barrier, blocking large-scale water seepage. The waterproof membrane layer adheres tightly to the outer wall of the sealing waterproof sleeve, achieving a seamless connection between the waterproof layer and the integrated waterproofing structure, preventing leakage gaps at the joint and ensuring the integrity of the waterproofing system. The covering waterproof protective layer provides physical protection for the waterproof membrane layer, resisting damage from mechanical impacts and friction during subsequent construction, while also isolating the waterproof membrane layer from environmental factors such as ultraviolet rays and humidity changes, delaying the aging of the waterproofing material, and extending the service life of the waterproof layer.

[0016] Furthermore, a transverse fixing steel bar is provided between two adjacent anchor rod bodies. The radial direction of the fixing steel bar is perpendicular to the radial direction of the anchor rod body, and the fixing steel bar is fixedly connected to each anchor rod body to form an integral load-bearing structure.

[0017] The horizontally fixed reinforcing bars connect adjacent anchor bolts to form an integrated load-bearing structure. This allows multiple anchor bolts to work together to bear the buoyancy of groundwater, preventing excessive deformation or displacement of a single anchor bolt due to concentrated stress, and improving the overall anti-buoyancy bearing capacity of the structure. The radial direction of the fixed reinforcing bars is perpendicular to the anchor bolt body, thus optimizing the force transmission path. This transforms the vertical buoyancy force borne by a single anchor bolt into a coordinated force for the entire structure, effectively distributing the load, reducing the stress on individual anchor bolts, and lowering the risk of damage due to overload.

[0018] Meanwhile, the overall load-bearing structure reduces local displacement of the anchor rods, preventing the displacement of a single anchor rod from pulling on the surrounding integrated waterproof structure and various structural layers. This ensures the fit and sealing between the waterproof components and the anchor rods, as well as the various structural layers, preventing leakage caused by loosening of the sealing connections due to displacement. Furthermore, the overall structure enhances the connection stability between the anchor rods and the basement floor slab and waterproof layer, reducing the damage to the waterproof system caused by structural deformation. This further improves the overall reliability of the basement structure and avoids the displacement and waterproofing failure problems caused by the dispersed and unevenly stressed distribution of traditional anchor rods.

[0019] Furthermore, both the upper and lower ends of the expansion waterstop are fixedly connected with annular waterstop rings, and the outer wall of the sealing waterproof sleeve is fitted with multiple layers of spaced expansion waterproof rings, which are tightly fitted with the sealing waterproof sleeve and the waterproof layer.

[0020] The annular water-stop rings at both ends of the expansion waterstop seal the ends of the waterstop, preventing water seepage from the gap between the waterstop end and the anchor rod or sealing waterproof sleeve, thus enhancing the overall sealing effect of the waterstop. The multi-layered, spaced expansion waterproof rings on the outer wall of the sealing waterproof sleeve fit tightly against the waterproof sleeve and waterproof layer, forming multiple annular sealing barriers: even if a minor leak occurs in the first waterproof ring, subsequent waterproof rings can continue to block the seepage path, preventing further spread of leakage. The tight fit between the expansion waterproof rings and the sealing waterproof sleeve and waterproof layer further fills the tiny gaps between them, enhancing the sealing performance of both.

[0021] The beneficial effects of this application are: 1. The anchor rod body penetrates the base layer, waterproof layer and basement floor slab in the vertical direction and is fixed to the base layer. It not only provides effective anti-buoyancy support for the basement structure and resists the lifting effect of groundwater buoyancy on the floor slab, ensuring the vertical stability of the structure, but also forms all-round sealing protection through the integrated waterproof structure. 2. The continuous waterproof coating acts directly on the surface of the anchor bolt, forming the first waterproof barrier, blocking the seepage path of groundwater along the surface of the anchor bolt and each structural layer, and sealing the waterproof sleeve to fill the gap between the anchor bolt and each layer, preventing the gap from becoming a seepage channel, thus achieving the combination of gap sealing and anchor bolt fixation. 3. By integrating the anti-buoyancy load-bearing function with the waterproof sealing function, the problem of leakage caused by incomplete sealing at the penetration points between traditional anti-buoyancy anchors and various structural layers, and the disconnect between anti-buoyancy and waterproof functions is solved, thereby achieving dual protection of anti-buoyancy stability and waterproof reliability.

[0026] The anchor structure for anti-buoyancy of basement structures provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0027] Example 1: like Figure 1 and Figure 2 As shown in the figure, this application provides an anchor structure for anti-buoyancy in basement structures, comprising: The base layer is 100, and a waterproof layer 110 and a basement floor slab 120 are sequentially installed on top of it. The anchor body 200 is installed vertically through the base layer 100, the waterproof layer 110 and the basement floor slab 120, and is fixedly connected to the base layer 100. The integrated waterproof structure 300 includes a continuous waterproof coating 310 applied to the surface of the anchor body 200, a sealed waterproof sleeve 320 fitted on the outside of the anchor body 200, an expansion waterstop 330 embedded in the waterproof sleeve, and a waterstop plate 340 fixed to the upper part of the anchor body 200. The waterstop plate 340 is flush with and sealed to the upper surface of the basement floor slab 120. The gaps between the anchor bolt body 200 and the waterproof layer 110 and the basement floor slab 120 are filled and sealed by the waterproof coating and the sealing waterproof sleeve 320.

[0028] In some embodiments of this application, such as Figure 1 As shown, the above-mentioned anchor structure for anti-buoyancy of basement structure is adopted. The anchor body 200 penetrates the base layer 100, waterproof layer 110 and basement floor slab 120 in the vertical direction and is fixed to the base layer 100. This not only achieves effective anti-buoyancy support for the basement structure, resists the lifting effect of groundwater buoyancy on the floor slab, and ensures the vertical stability of the structure, but also forms all-round sealing protection through the integrated waterproof structure 300.

[0029] The continuous waterproof coating 310 acts directly on the anchor bolt surface, forming the first waterproof barrier and blocking the seepage path of groundwater along the anchor bolt surface and various structural layers. The sealing waterproof sleeve 320 fills the gaps between the anchor bolt and each layer, preventing the gaps from becoming seepage channels and achieving a combination of gap sealing and anchor bolt fixation. The waterstop plate 340 is flush with the upper surface of the basement floor slab 120, sealing any potential leakage gaps from the top of the structure and further preventing surface water from seeping in. By integrating the anti-buoyancy load-bearing function with the waterproof sealing function, the leakage problems caused by incomplete sealing at the penetration points between traditional anti-buoyancy anchor bolts and various structural layers, and the disconnect between anti-buoyancy and waterproof functions, are solved, thus achieving dual protection of anti-buoyancy stability and waterproof reliability.

[0030] Example 2: This application provides an anchor structure for anti-buoyancy of basement structures. In addition to the above-mentioned technical features, the anchor structure for anti-buoyancy of basement structures in this application also includes the following technical features.

[0031] like Figure 1 and Figure 2 As shown, the expansion waterstop 330 is wound around the anchor rod body 200 in the circumferential direction, and the space between adjacent winding sections of the expansion waterstop 330 is filled with a sealing medium.

[0032] The expansion waterstop 330 is wound circumferentially around the anchor bolt body 200, effectively increasing the contact area with the anchor bolt surface and forming a continuous annular sealing barrier, thus enhancing the sealing effect on the through gaps. The sealing medium filling the gaps between adjacent winding sections can fill the tiny gaps at the joints of the waterstop windings, preventing water from seeping in from the joint gaps.

[0033] The 330 expansion waterstop is a putty-type expansion waterstop. The sealing medium can be asphalt caulking material or grease-based sealing medium. Because the 330 expansion waterstop itself has the property of expanding when it comes into contact with water, it forms a double protection effect when combined with the filling and sealing effect of the sealing medium: when a small amount of water seeps into the waterstop area, the waterstop expands after contact with water and further squeezes the gap, enhancing the sealing effect; the sealing medium improves the sealing performance and structural integrity of the joint, preventing gaps from appearing at the joint due to stress or deformation, thus solving the problem of loose waterstop joints and easy formation of leakage channels.

[0034] Example 3: This application provides an anchor structure for anti-buoyancy of basement structures. In addition to the above-mentioned technical features, the anchor structure for anti-buoyancy of basement structures in this application also includes the following technical features.

[0035] like Figure 1 and Figure 2 As shown, the continuous waterproof coating 310 covers the entire area of ​​the anchor body 200 penetrating the base layer 100, the waterproof layer 110, and the basement floor slab 120, and the waterproof coating extends to the outside of the penetrating section below the bottom of the base layer 100 and above the waterproof layer 110.

[0036] In this embodiment, the continuous waterproof coating 310 covers the entire area of ​​the anchor bolt body 200 penetrating each structural layer, thereby forming a surface seal protection without dead angles and blocking the seepage path of groundwater between the anchor bolt surface and the base layer 100, the waterproof layer 110, and the basement floor slab layer 120. The coating extends below the bottom of the base layer 100, which can intercept deep underground seepage water, thereby reducing the risk of seepage water penetrating upwards along the anchor bolt root from the source; extending to the outside of the penetrating section above the waterproof layer 110, it forms additional sealing protection at the upper connection between the anchor bolt and the basement floor slab layer 120, thereby compensating for the weak sealing point above the penetrating part.

[0037] Meanwhile, the continuous, uninterrupted coating design avoids the sealing gaps that occur due to insufficient coverage in traditional waterproof coatings. At the same time, the coating is tightly bonded to the surface of the anchor bolt, forming a strong protective layer that can protect against groundwater erosion and reduce damage to the anchor bolt from the external environment, thus extending the service life of the anchor bolt.

[0038] Example 4: This application provides an anchor structure for anti-buoyancy of basement structures. In addition to the above-mentioned technical features, the anchor structure for anti-buoyancy of basement structures in this application also includes the following technical features.

[0039] like Figure 1 and Figure 2 As shown, the waterproof layer 110 comprises the following components arranged sequentially from bottom to top: Coating reinforcement layer 111; Waterproof coating layer 112; Waterproof membrane layer 113; Among them, the coating reinforcement layer 111 is bonded to the surface of the base layer 100, the waterproof membrane layer 113 is tightly bonded to the outer wall of the sealing waterproof sleeve 320, and a covering waterproof protective layer 114 is provided above the waterproof membrane layer 113.

[0040] In this embodiment, the coating reinforcement layer 111 adheres tightly to the surface of the base layer 100, effectively enhancing the adhesion between the subsequent waterproof coating layer 112 and the base layer 100, and preventing the waterproof coating layer 112 from peeling off from the base layer 100, thus preventing waterproofing failure. The waterproof coating layer 112 and the waterproof membrane layer 113 form a composite waterproof structure, with the two waterproof materials complementing each other: the waterproof coating layer 112 can fill the tiny pores and cracks on the surface of the base layer 100; the waterproof membrane layer 113 forms a large-area continuous protective barrier, blocking large-scale water seepage. The waterproof membrane layer 113 adheres tightly to the outer wall of the sealed waterproof sleeve 320, achieving a seamless connection between the waterproof layer 110 and the integrated waterproof structure 300, preventing leakage gaps at the joint, and ensuring the integrity of the waterproof system. The covering waterproof protective layer 114 provides physical protection for the waterproof membrane layer 113, resisting damage from mechanical collisions and friction during subsequent construction, while also isolating the waterproof membrane layer 113 from environmental factors such as ultraviolet rays and humidity changes, delaying the aging of the waterproof material, and extending the service life of the waterproof layer 110.

[0041] Example 5: This application provides an anchor structure for anti-buoyancy of basement structures. In addition to the above-mentioned technical features, the anchor structure for anti-buoyancy of basement structures in this application also includes the following technical features.

[0042] like Figure 1 and Figure 2 As shown, a transverse fixing steel bar 210 is provided between two adjacent anchor rod bodies 200. The radial direction of the fixing steel bar is perpendicular to the radial direction of the anchor rod body 200, and the fixing steel bar is fixedly connected to each anchor rod body 200 to form an integral load-bearing structure.

[0043] In this embodiment, the transverse fixing steel bars 210 connect adjacent anchor rod bodies 200 to form an integral load-bearing structure. This allows multiple anchor rods to work together to bear the buoyancy of groundwater, preventing excessive deformation or displacement of a single anchor rod due to concentrated stress, and improving the overall anti-buoyancy bearing capacity of the structure. The fixing steel bars are radially perpendicular to the anchor rod body 200, thereby optimizing the force transmission path. This transforms the vertical buoyancy borne by a single anchor rod into a coordinated force for the entire structure, effectively dispersing the load, reducing the stress burden on a single anchor rod, and lowering the risk of damage to the anchor rod due to overload.

[0044] Meanwhile, the overall load-bearing structure reduces local displacement of the anchor rods, preventing the displacement of a single anchor rod from pulling on the surrounding integrated waterproof structure 300 and other structural layers. This ensures the fit and sealing between the waterproof components and the anchor rods, as well as the various structural layers, preventing leakage caused by loosening of the sealing connections due to displacement. Furthermore, the overall structure enhances the connection stability between the anchor rods and the basement floor slab 120 and the waterproof layer 110, reducing the damage to the waterproof system caused by structural deformation. This further improves the overall reliability of the basement structure and avoids the displacement and waterproofing failure problems caused by the dispersed arrangement and uneven stress of traditional anchor rods.

[0045] Example 6: This application provides an anchor structure for anti-buoyancy of basement structures. In addition to the above-mentioned technical features, the anchor structure for anti-buoyancy of basement structures in this application also includes the following technical features.

[0046] like Figure 1 and Figure 2 As shown, both the upper and lower ends of the expansion waterstop 330 are fixedly connected with annular waterstop rings 331, and the outer wall of the sealing waterproof sleeve 320 is fitted with multiple layers of spaced expansion waterproof rings 332, which are tightly fitted with the sealing waterproof sleeve 320 and the waterproof layer 110.

[0047] The annular water-stop rings 331 at both ends of the expansion waterstop 330 form a seal at the ends of the waterstop, preventing water seepage from the gap between the waterstop end and the anchor rod or the sealing waterproof sleeve 320, thus enhancing the overall sealing effect of the waterstop. The multi-layered, spaced expansion waterproof rings 332 on the outer wall of the sealing waterproof sleeve 320 fit tightly against the waterproof sleeve and waterproof layer 110, forming multiple annular sealing barriers: even if a minor leak occurs in the first waterproof ring, subsequent waterproof rings can continue to block the seepage path, preventing further spread of leakage. The tight fit between the expansion waterproof rings 332 and the sealing waterproof sleeve 320 and waterproof layer 110 further fills the tiny gaps between the waterproof sleeve and waterproof layer 110, enhancing their sealing performance.
