Description
Technical Field
[0001] This invention belongs to the field of swimming pool waterproofing construction technology, and in particular relates to a swimming pool waterproofing structure and construction method with externally installed pipelines. Background Technology
[0002] With the increasing demand for healthy living and leisure spaces, swimming pool construction is no longer limited to traditional civil engineering methods. Modern swimming pool structures have developed a variety of technological approaches to adapt to different site conditions (such as rooftops, indoor spaces, and temporary locations), usage needs (private / public), and budget considerations. Especially when adding swimming pools to high-rise buildings or existing buildings, structural safety, load-bearing capacity, and waterproofing performance become key decision-making factors.
[0003] Most swimming pool walls are equipped with lighting fixtures, and some of the conduits for these fixtures penetrate the waterproof membrane during installation. Although waterproof coating is applied at the penetration points, there is still a possibility of leakage. Therefore, a pool waterproofing structure and construction method with external conduits is needed. By placing the conduits on the outside of the waterproof membrane, the conduits are prevented from penetrating the membrane, thus avoiding weak points in the waterproofing system and optimizing the overall reliability of the waterproofing system. Furthermore, since the conduits are partially exposed, the connections between the conduits and the tiled surfaces and overflow troughs are reinforced and decorated, improving both the structural stability of the conduit installation and the aesthetic appeal, thereby optimizing the feasibility of avoiding penetration of the waterproof membrane. Summary of the Invention

By placing the conduits on the outside of the waterproof membrane, the conduits are prevented from penetrating the waterproof membrane, thus avoiding weak points in the waterproof system and optimizing the overall reliability of the waterproof system. Furthermore, the connection between the conduits and the laid tiles and overflow trough grating is reinforced and decorated, improving both the stability of the conduit installation structure and the aesthetic appeal. This optimizes the feasibility of avoiding conduit penetration of the waterproof membrane, thereby solving the aforementioned technical problems.

Anchoring holes are formed on the surface of the pool foundation. Anchor rods are inserted into the inner cavities of the anchoring holes. A connecting assembly is provided between the anchor rods and the conduits. A rebar adhesive layer is filled between the inner wall of the anchoring holes and the anchor rods. A clamp assembly is provided on the surface of the conduits. A sleeve block one is provided on the surface of the clamp assembly. A sleeve block two is fixedly connected to the surface of the grid plate. A sleeve block three is adhered to the surface of the decorative ceramic tile layer by a metal block. A nut block four is threadedly connected to the surface of the anchor rods. A weather-resistant silicone filler layer is filled between the grid plate, the conduits, and the decorative ceramic tile layer.
[0006] Preferably, a pad is fitted onto the surface of the anchor rod.
[0007] Preferably, the connecting assembly includes a clamping block disposed between the anchor rod and the conduit, and side blocks are provided on the outer sides of both the anchor rod and the conduit. A bolt rod is installed through the clamping block and the side blocks, and a nut block is threadedly connected to the surface of the bolt rod.
[0008] Preferably, the surface of the anchor rod is integrally formed with a support bar.
[0009] Preferably, the anchor rod has a threaded connection to a second nut block, which fits into the surface of the pool foundation.
[0010] Preferably, the surface of the conduit is provided with a wrapping material block, and the wrapping material block is fixed to the waterproof membrane layer by heat fusion bonding.
[0011] Preferably, the clamp assembly includes a first sleeve block disposed on the surface of the conduit, a second sleeve block and a threaded rod rotatably connected to the surface of the first sleeve block, a third nut block threadedly connected to the surface of the threaded rod, an elastic washer sleeved on the surface of the threaded rod, and the second sleeve block and the first sleeve block are welded together.
[0012] Preferably, both sleeve block three and sleeve block two are sleeved on the surface of the anchor rod.
[0013] Preferably, the end of the conduit extends into the inner cavity of the decorative light trough.
[0014] A construction method for an externally installed waterproof pool structure, the steps of which are as follows: First, the anchoring holes are drilled and cleaned. Then, the anchor rod is fixed to the inner cavity of the anchoring hole using the rebar adhesive layer. Next, the clamping block and edge block are fixed to the surface of the conduit and anchor rod using the cooperation of the bolt rod and nut block, so that the conduit is fixed to the anchor rod, thereby improving the stability of the conduit installation position and preventing displacement and twisting due to external forces during subsequent material pouring. Then, a waterproof coating is applied to the surface of the pool foundation for waterproofing. Next, the positioning lines of the masonry wall structural columns are marked in advance to reserve the position of the structural columns for subsequent rebar installation. The mixed DS mortar is evenly spread and leveled to a thickness of 20mm. Then, during the window period from the initial setting to the final setting of the mortar, three processes are continuously completed: scraping, smoothing with a wooden trowel, and compacting and finishing with a steel trowel. Finally, a flat, dense, and crack-free surface is formed. After the final setting, timely spray curing is carried out for no less than seven days to form a strong, complete, and permanent protective layer. Then, on the completed rigid waterproof layer and 20mm thick DS mortar protective layer, the position lines of the block wall are accurately marked according to the drawings. The longitudinal steel bars of the structural columns are installed according to the design requirements, and a pull-out test is carried out. At the root of the installed steel bars, a waterproof membrane layer must be laid with the steel bars as the center to seal the weak node. When the block wall is built, the wall penetration holes for wall lamps and other conduits must be reserved in advance according to the electromechanical drawings. Second, by tightening the threaded rod and nut block three, the first and second wrapping blocks are clamped onto the surface of the anchor rod and the conduit, and the second wrapping block drives the sleeve block to be fitted onto the surface of the anchor rod. Then, the grid plate is laid on the top of the pool overflow channel, so that the grid plate drives the sleeve block two to be fitted onto the surface of the anchor rod. Third, after the pipeline laying and joint sealing are completed, a concrete protective layer is poured to permanently cover and protect the buried pipelines and waterproof layer. A polymer cement mortar bonding layer is used to lay the decorative ceramic tile layer. After laying, DWS waterproof mortar is used for grouting to ensure the joints are full and dense. The decorative ceramic tile layer on the top of the pool foundation will have pre-formed metal blocks. By welding and fixing a sleeve block three to the surface of the metal block, the decorative ceramic tile layer can be moved to fit onto the surface of the anchor rod during installation. Then, the nut block four is tightened to the anchor rod, fixing the grid plate laid on the top of the pool to the pipeline and anchor rod, further improving the stability of the connection between the decorative ceramic tile layer, grid plate, anchor rod, and pipeline. Subsequently, a weather-resistant silicone filler layer is filled and sealed on the surface of the pipeline, improving aesthetics. By placing the pipeline on the outside of the waterproof membrane layer, the pipes are prevented from penetrating the waterproof membrane, improving the reliability of the overall waterproof structure of the pool and effectively preventing subsequent water leakage.
[0015] The beneficial effects of this invention are: This invention connects and fixes the conduit to the anchor rod using a connecting component, improving the stability of the conduit structure. Furthermore, by fixing sleeves one, two, and three to the surface of the anchor rod using nut block four, the overall integrity of the connection between the exposed conduit, the grid plate, and the decorative tile layer is further enhanced. Subsequently, a weather-resistant silicone filler layer is applied to the surface of the conduit for sealing, improving the aesthetics of the joints. This achieves the goal of optimizing the overall reliability of the waterproofing system by placing the conduit outside the waterproof membrane, preventing it from penetrating the membrane and creating weak points. Additionally, the connection between the conduit and the laid tiles and overflow trough grid plate is reinforced and decorated, improving both the stability of the conduit installation structure and the aesthetic appeal, thereby optimizing the feasibility of the conduit avoiding penetration of the waterproof membrane.

[0019] The embodiments described herein are specific implementations of the present invention, used to illustrate the concept of the invention, and are illustrative and exemplary, and should not be construed as limiting the implementation or scope of the invention. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application.

[0020] The accompanying drawings in this specification are schematic diagrams to aid in illustrating the concept of the invention, and schematically show the shapes of the various parts and their interrelationships. Please note that, in order to clearly demonstrate the structure of the components in the embodiments of the invention, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.
[0021] Example 1: Figure 1-7This invention illustrates an embodiment of an externally mounted waterproof swimming pool structure, comprising a DS mortar layer 1 applied to the surface of the pool base; an aerated concrete block layer 2 fixedly connected to the surface of the DS mortar layer 1; a waterproof membrane layer 3 laid on the surface of the aerated concrete block layer 2; a conduit 4 pre-embedded in the inner cavity of the DS mortar layer 1; a cast concrete protective layer 5 applied to the outer sides of the waterproof membrane layer 3 and the conduit 4; a decorative ceramic tile layer 6 adhered to the surface of the cast concrete protective layer 5; a mesh plate 7 laid on the outer side of the conduit 4; and anchoring holes 9 formed in the surface of the pool base on the outer side of the conduit 4. An anchor rod 10 is inserted into the inner cavity of the anchor hole 9. A connecting component 11 is provided between the anchor rod 10 and the conduit 4. A rebar adhesive layer 12 is filled between the inner wall of the anchor hole 9 and the anchor rod 10. A clamping component 16 is provided on the surface of the conduit 4. A sleeve block 17 is provided on the surface of the clamping component 16. A sleeve block 29 is fixedly connected to the surface of the grid plate 7. A sleeve block 31 is glued to the surface of the decorative tile layer 6 through a metal block 20. A nut block 42 is threadedly connected to the surface of the anchor rod 10. A weather-resistant silicone filler layer 8 is filled between the grid plate 7, the conduit 4, and the decorative tile layer 6.
[0022] A construction method for an externally installed waterproof swimming pool structure, the construction method is as follows: First, the anchoring hole 9 is drilled and cleaned. Then, the anchor rod 10 is fixed to the inner cavity of the anchoring hole 9 using the anchoring adhesive layer 12. Next, the clamping block 111 and the edge block 112 are fixed to the surface of the conduit 4 and the anchor rod 10 by the cooperation of the bolt rod 113 and the nut block 114, so that the conduit 4 can be fixed to the anchor rod 10, thereby improving the stability of the conduit 4 installation position and preventing displacement and twisting due to external forces during subsequent material pouring. Then, a waterproof coating is applied to the surface of the pool foundation for waterproofing. Next, the positioning lines of the masonry wall structural columns are marked in advance to reserve the position of the structural columns for subsequent rebar installation. The mixed DS mortar is then evenly applied. Spread and level the mortar to a thickness of 20mm. Then, within the window period from initial setting to final setting of the mortar, continuously complete the three processes of leveling, smoothing with a wooden trowel, and compacting and finishing with a steel trowel to finally form a flat, dense, and crack-free surface. After final setting, spray curing should be carried out for no less than seven days to form a strong, complete, and permanent protective layer. Then, on the completed rigid waterproof layer and 20mm thick DS mortar protective layer, accurately mark the position lines of the block wall according to the drawings. Install the longitudinal steel bars of the structural columns according to the design requirements and conduct a pull-out test. At the root of the steel bar, a waterproof membrane layer 3 must be laid with the steel bar as the center to seal the weak node. When building the block wall, the wall penetration holes for wall lamps and other conduits should be reserved in advance according to the electromechanical drawings. Second, by tightening the threaded rod 163 and the nut block 3 164, the first 161 and the second 162 are clamped onto the surface of the anchor rod 10 and the conduit 4, and the second 162 drives the first sleeve block 17 to be fitted onto the surface of the anchor rod 10. Then, the grid plate 7 is laid on the top of the pool overflow channel, and the grid plate 7 drives the second sleeve block 19 to be fitted onto the surface of the anchor rod 10. Third, after the pipeline laying and joint sealing are completed, a concrete protective layer 5 is poured as a whole to provide permanent coverage and protection for the buried pipelines and waterproof layer. The finishing tile layer 6 is then laid using a polymer cement mortar bonding layer. After laying, DWS waterproof mortar is used for grouting to ensure the joints are full and dense. The finishing tile layer 6 on top of the pool foundation will have a pre-formed metal block 20. A fixing sleeve 21 is welded to the surface of the metal block 20, allowing the finishing tile layer 6 to be installed so that the sleeve 21 fits onto the surface of the anchor rod 10. Then, the nut block 422 is tightened with the anchor rod 10, so that the grid plate 7 laid on the top of the pool can be fixed between the conduit 4 and the anchor rod 10, which further improves the stability of the connection between the decorative tile layer 6, the grid plate 7, the anchor rod 10 and the conduit 4. Subsequently, the surface of the conduit 4 is filled with a weather-resistant silicone filler layer 8 for sealing, which improves the aesthetics. By placing the conduit 4 on the outside of the waterproof membrane layer 3, the situation of the pipe passing through the waterproof membrane is avoided, which improves the reliability of the overall waterproof structure of the pool and effectively prevents subsequent water leakage.
[0023] Example 2: Refer to Figure 1-3 Similar to Embodiment 1, but with a further improvement: a pad 18 is fitted onto the surface of the anchor rod 10. The pad 18 protects the bottom of the sleeve block 17, improving the stability of the sleeve block 17's position. The connecting assembly 11 includes a clamping block 111 positioned between the anchor rod 10 and the conduit 4. Side blocks 112 are provided on the outer sides of both the anchor rod 10 and the conduit 4. A bolt rod 113 is threaded through the clamping block 111 and the side blocks 112. A threaded connection is made to the surface of the bolt rod 113. The surface of the anchor rod 10 is integrally formed with a support strip 13. The support strip 13 increases the contact area between the anchor rod 10 and the anchoring adhesive layer 12, thereby improving the stability of the anchor rod 10 in the inner cavity of the anchoring hole 9. The surface of the anchor rod 10 is threaded with a nut block 14. The nut block 14 fits against the surface of the pool foundation. The nut block 14 tightens the anchor rod 10 and the pool foundation, further improving the reliability of the anchor rod 10.
[0024] Example 3: Refer to Figure 4-7Similar to Embodiment 1, but further: the surface of the conduit 4 is provided with a wrapping material block 15, which is fixed to the waterproof membrane layer 3 by hot melt bonding. The wrapping material block 15 increases the contact area between the waterproof membrane layer 3 and the conduit 4, thereby improving the firmness of the connection between the conduit 4 and the waterproof membrane layer 3. The clamp assembly 16 includes a first wrapping block 161 provided on the surface of the conduit 4. The surface of the first wrapping block 161 is rotatably connected to a second wrapping block 162 and a threaded rod 163. The surface of the threaded rod 163 is threadedly connected to a third nut block 164. An elastic washer 165 is sleeved on the surface of the threaded rod 163. The second wrapping block 162 is welded to the first sleeve block 17. The third sleeve block 21 and the second sleeve block 19 are both sleeved on the surface of the anchor rod 10. The end of the conduit 4 extends into the inner cavity of the decorative light trough.
[0025] In summary, this externally mounted pool waterproofing structure and construction method connects and fixes the conduit 4 to the anchor rod 10 via the connecting component 11, improving the structural stability of the conduit 4. Furthermore, the use of nut block 22 to fix sleeve block 17, sleeve block 29, and sleeve block 31 to the surface of the anchor rod 10 further enhances the overall integrity of the connection between the exposed conduit 4, the grid plate 7, and the decorative tile layer 6. Subsequently, a weather-resistant silicone filler layer 8 is applied to the surface of the conduit 4 for sealing, improving the aesthetics of the joints. This achieves the goal of optimizing the overall reliability of the waterproofing system by placing the conduit outside the waterproof membrane, preventing it from penetrating the membrane and creating weak points. Additionally, the connection between the conduit and the laid tiles and overflow trough grid plate is reinforced and decorated, improving both the structural stability and aesthetics of the conduit installation, thus optimizing the feasibility of preventing the conduit from penetrating the waterproof membrane.
