Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically a construction method for a PVC waterproof membrane for swimming pool bottom slabs. Background Technology

[0002] With the improvement of living standards, people's awareness of fitness has also increased. Swimming, as an aerobic exercise, is becoming increasingly popular. The temperature-controlled and clean environment of swimming pools provides a modern sports and fitness venue for the general public. Investment in swimming pool construction projects is also increasing across the country. The difficulty and key point of swimming pool construction projects is solving the waterproofing problem. Standard swimming pools are generally around 50 meters long, which is considered an extra-long structure. Cracks are prone to occur during construction, and the key is whether the waterproofing of the base slab can meet the requirements.

[0003] Traditional ceramic tiles not only lack internal waterproofing but are also prone to detachment and cracking due to thermal expansion and contraction, severely damaging the underlying waterproofing. Completely resolving this requires removing all tiles, redoing the waterproofing, and then re-tiling, resulting in significant expenses. With the decrease in raw material prices and the maturity of technology, pool liner systems have gradually entered the public eye, replacing traditional methods and gaining widespread application. Pool liner systems are corrosion-resistant, UV-resistant, and have good temperature resistance, providing excellent internal waterproofing. They also offer anti-slip properties, ensuring the safety of swimmers. To guarantee superior waterproofing performance, current construction processes require applying adhesive to the entire pool bottom and laying the liner simultaneously to ensure complete adhesion to the base. However, because the liner installation requires complete bonding between the concrete and the liner without any gaps, bubbling will occur, causing unevenness in the base and affecting usability. Furthermore, the need for comprehensive adhesive application leads to a long construction period, requiring uninterrupted application, bonding, and adhesion of the liner throughout the entire process. This continuous construction demands high levels of worker fatigue and is costly. Summary of the Invention

[0004] The present invention aims to solve the above problems and thus provide a construction method for a PVC waterproof membrane for swimming pool bottom that does not require continuous construction.

[0005] The technical solution adopted by the present invention to solve the aforementioned problem is as follows:

[0006] A method for constructing a PVC waterproof membrane for swimming pool floor includes the following steps:

[0007] S1: Based on the pool design dimensions, the waterproof membranes are laid out according to the rule that the edge of the waterproof membrane closer to the center of the pool overlaps the edge of the waterproof membrane further away from the center of the pool. A layout drawing is then produced, and the waterproof membranes are cut according to the layout drawing.

[0008] S2: After the pool floor is constructed, the center line and outer wall line of the pool are laid out on the pool floor. According to the layout drawing and with the center line of the pool as the reference, the positions of each waterproof membrane are laid out on the floor.

[0009] S3: Determine the horizontal overlap position of the waterproof membrane on the base plate according to the layout diagram. After the overlap position is determined, apply a waterproof coating and fix the PVC membrane on the waterproof coating with screws.

[0010] S4: Lay the waterproof membrane on the base plate according to the rule of starting from the middle of the pool and gradually overlapping towards the pool wall. Heat fuse the waterproof membrane to the outer wall of the pool, ensuring that the horizontal overlap of the waterproof membrane is above the PVC membrane.

[0011] S5: The waterproof membrane and PVC membrane are bonded together with waterproof adhesive. The overlapping parts of adjacent waterproof membranes and the side closer to the edge of the lower waterproof membrane are bonded with heat fusion. The overlapping parts of adjacent waterproof membranes and the side closer to the edge of the upper waterproof membrane are bonded with waterproof adhesive.

[0012] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0013] The traditional method of applying glue to the base plate is replaced by laying a waterproof coating at intervals along the width of the pool base plate. The two ends of the waterproof membrane are fixed on top of the PVC membrane, and the middle of the waterproof membrane is pressed against the base plate due to water pressure and will not move. Adjacent waterproof membranes are connected by overlapping. The waterproof performance of the overlapping areas is ensured by hot melting and waterproof adhesive. The waterproof performance of the overlapping areas is further enhanced by the PVC membrane and waterproof coating, which also ensures the overall waterproof effect. This method not only ensures the quality of the project, but also reduces the rate of blistering, reduces the fatigue of workers working continuously, saves materials, and reduces construction costs.

[0014] As a preferred embodiment, a further technical solution of the present invention is:

[0015] When laying out the waterproof membrane, the width of the waterproof membrane should be ≥ 1 / 3 of the width of the roll material and ≥ 300mm.

[0016] The overlap width between adjacent waterproof membranes is ≥100mm.

[0017] The width of the waterproof coating is greater than 14cm.

[0018] The width of the PVC membrane is less than or equal to the width of the waterproof coating.

[0019] When hot-melting the overlap of adjacent waterproof membranes, the connection is first hot-melted using an automatic hot-melt machine, and then the start and end points are hot-melted using a manual hot-melt machine. Attached Figure Description

[0023] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0024] A method for constructing a PVC waterproof membrane for swimming pool floor includes the following steps:

[0025] S1: Based on the pool design dimensions, the waterproof membrane 1 is laid out and a layout drawing is produced, with the edge of the waterproof membrane 1 near the center of the pool overlapping the edge of the waterproof membrane 1 away from the center of the pool. The waterproof membrane 1 is then cut according to the layout drawing. When laying out the waterproof membrane 1, the width of the waterproof membrane 1 is ≥ 1 / 3 of the roll width and ≥ 300mm, and the overlap width between adjacent waterproof membrane 1 is ≥ 100mm.

[0026] S2: After the pool base plate 2 is constructed, the center line and outer wall line of the pool are laid out on the pool base plate 2. According to the layout drawing and with the center line of the pool as the reference, the position lines of each waterproof membrane 1 are laid out on the base plate 2. Before laying out the lines, the pool base plate 2 is re-measured to ensure that the unevenness tolerance of the base plate 2 is within 5mm / m2. Any base plate 2 that does not meet the requirements is repaired.

[0027] S3: Clean the base plate 2 thoroughly with clean water to ensure there is no dust or other debris. According to the layout diagram, determine the horizontal overlap position of the waterproof membrane 1 on the base plate 2. The horizontal overlap position of the waterproof membrane 1 is along the width of the pool. After determining the overlap position, apply the waterproof coating 3. Fix the PVC membrane 4 on the waterproof coating 3 with screws. There should be no air bubbles or wrinkles between the PVC membrane 4 and the waterproof coating 3. The width of the waterproof coating 3 should be greater than 14cm. The PVC membrane 4 should sit on the waterproof coating 3 and its width should be less than or equal to the width of the waterproof coating 3.

[0028] S4: Lay the waterproof membrane 1 on the base plate 2 according to the rule of starting from the middle of the pool and gradually overlapping towards the pool wall. Before laying the waterproof membrane 1, clean the base plate 2 to avoid damage caused by foreign objects. The waterproof membrane 1 should be in close contact with the base plate 2. When laying, the waterproof membrane 1 should not be stretched or wrinkled. Press the waterproof membrane 1 firmly and flat. Heat fuse the waterproof membrane 1 to the outer wall of the pool. Ensure that the horizontal overlap of the waterproof membrane 1 is above the PVC membrane 4. Through the waterproof coating 3 and PVC membrane 4 set along the width of the pool, the two ends of the waterproof membrane 1 along the length of the pool can be respectively located on the PVC membrane 4.

[0029] S5: The contact points between the waterproof membrane 1 and the PVC membrane 4 are bonded with waterproof adhesive 5. The overlap of adjacent waterproof membranes 1 and the side closer to the edge of the lower waterproof membrane 1 are connected by heat fusion. First, the connection points are heat-fused using an automatic heat fusion machine. The heat fusion connection should be continuous and the temperature constant to ensure the heat fusion quality. Then, the starting and ending points are touched up with a manual heat fusion machine. The positions heat-fused by the automatic heat fusion machine are inspected, and any positions with unqualified heat fusion quality are repaired. The overlap of adjacent waterproof membranes 1 and the side closer to the edge of the upper waterproof membrane 1 are bonded with waterproof adhesive 5. Before bonding, the contact surfaces are cleaned and wiped clean with alcohol to avoid foreign matter affecting the bonding quality. When bonding, it should be bonded firmly from the inside out to avoid air pockets.

[0030] Avoid laying the tubing around the drain outlet and continue laying along the edge of the drain outlet. After construction is complete, conduct a sealing test on the pool. During the test, fill the pool with water. For pools deeper than 2m, the filling should be done in two stages, with an interval of no less than 24 hours between the two stages. The depth of each filling should not exceed 2m. After each filling, the water level drop should be measured over 24 hours to calculate the leakage. The appearance of the pool should be inspected during and after filling. If any leakage is found, the process should be stopped immediately and repairs should be made.

[0031] The traditional method of applying glue to the base plate is replaced by laying a waterproof coating at intervals along the width of the pool base plate. The two ends of the waterproof membrane are fixed on top of the PVC membrane, and the middle of the waterproof membrane is pressed against the base plate due to water pressure and will not move. Adjacent waterproof membranes are connected by overlapping. The waterproof performance of the overlapping areas is ensured by hot melting and waterproof adhesive. The waterproof performance of the overlapping areas is further enhanced by the PVC membrane and waterproof coating, which also ensures the overall waterproof effect. This method not only ensures the quality of the project, but also reduces the rate of blistering, reduces the fatigue of workers working continuously, saves materials, and reduces construction costs.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes made based on the description and drawings of the present invention are included within the scope of the present invention.
