What are the factors related to the load-bearing capacity of a family suspended acrylic swimming pool?

As a focus on family suspended acrylic swimming pool research and development of enterprises, we know that one of the core safety indicators of such products is the load-bearing capacity -- after all, family suspended acrylic swimming pool is a special structure of suspended installation, its ability to stably carry the body of water, the user and its own weight, is directly related to the safety of the family use. After years of accumulation of technology, we found that the family suspended acrylic swimming pool load-bearing capacity is not a single factor to determine, but by the material, structure, installation and other aspects of the joint role of the results.

First of all, the performance of the acrylic material itself is the foundation. Family suspended acrylic swimming pool body depends entirely on the construction of acrylic sheet, its load-bearing capacity is closely related to the thickness and purity of the sheet. Our company's family suspended acrylic swimming pool are imported high-purity acrylic sheet, thickness according to the pool size from 12mm to 30mm varies: small parent-child models (capacity 1.5-3 tons) selection of 12-15mm sheet, through the molecular polymerization process to enhance the tensile strength; large family models (capacity of 5-8 tons) are used in the 20-30mm thicker sheet, and the edge of the pool to do arc Reinforcement treatment, so that the local load-bearing capacity increased by 40%. Inferior acrylic due to impurities, uneven density, often in the load-bearing value of more than 30% of the design value of cracking, and our material has been tested to withstand the design of the load-bearing 1.5 times the pressure.

Secondly, the design of the support structure is key. Family suspended acrylic swimming pool “suspension” is not really suspended, but through the wall embedded brackets, steel structure overhangs and other ways to achieve, the load-bearing capacity of the support structure directly determines the overall stability. In our customized program, the support structure will be individually designed according to the installation environment (such as concrete wall, light steel wall): if installed in the concrete wall, it will use galvanized steel bracket fixed by expansion bolts, each bracket load-bearing capacity of not less than 2 tons, and the spacing of the bracket is controlled to be within 50cm, to ensure uniform force; if it is a light steel wall, it will be paired with an aluminum alloy reinforcing parts, through " If the wall is made of light steel, it is equipped with aluminum alloy reinforcement to avoid local overload by means of “decentralized stress + internal wall support”. There was a customer request to install the family suspended acrylic swimming pool on the second floor, we calculated the floor loading and added 4 additional ground support columns, so that the overall load bearing is dispersed to the main beams of the floor, completely eliminating the potential safety hazards.

Furthermore, the mechanical design of the pool structure should not be ignored. Family suspended acrylic swimming pool shape, edge treatment will affect the distribution of force: square pool at right angles are prone to stress concentration, and we use the oval or rounded rectangular design, the water pressure can be evenly dispersed to the entire pool wall; the pool bottom is a “micro-arc arch” structure, similar to the principle of the arch bridge, through the upward force to offset the downward weight of some of the finite element. The bottom of the pool adopts a “micro-arch” structure, similar to the principle of an arch bridge, which counteracts the downward weight by the upward supporting force. In addition, we will add a silicone cushioning layer to the connection between the pool body and the support structure, not only to avoid the loss caused by direct friction between metal and acrylic, but also to cushion the instantaneous impact through elastic deformation (e.g., when someone jumps into the pool).

The precision of the installation process will also indirectly affect the load-bearing performance. Even if the materials and design are up to standard, if the brackets are not securely fastened during installation and the pool body does not fit well enough to the supporting structure, the load-bearing capacity will be reduced. Our installation team will use a laser level to calibrate the level of the pool body, the error is controlled within 2mm, to ensure that each support point is uniformly stressed; for the connection between the wall and the bracket, it will be carried out the “second fastening” - after the initial installation of 24 hours, to wait until the material stress is released, then the bolts are rechecked and reinforced to prevent loosening during long-term use. Years of data show that the actual load-bearing performance of a home suspended acrylic pool installed in a standardized manner can reach more than 95% of its design value, whereas this percentage may drop to less than 70% for a product that is not installed in a standardized manner.

Finally, the use of the process of maintenance also affects the stability of load-bearing. Family suspended acrylic swimming pool body if long-term exposure to high temperatures (such as more than 40 ℃ hot water) or chemical corrosives (such as high concentration of disinfectants), will lead to acrylic aging, indirectly reducing the load-bearing capacity. We will remind customers: the water temperature should be controlled within 38 ℃, after each water change need to use neutral detergent to clean the pool body; every year need to check the corrosion of the support structure, and timely replacement of the aging silicone cushion layer. Through these details of maintenance, can ensure that the family suspended acrylic swimming pool in 15 years of use cycle, load-bearing capacity of not more than 10% attenuation.

In short, the weight-bearing capacity of a family suspended acrylic swimming pool is the result of the joint action of materials, design, installation and maintenance. As a manufacturer, we strictly control from each link, just to let families enjoy the convenience and beauty of the suspended pool, more peace of mind to rely on its stable load-bearing performance.
