Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a prefabricated swimming pool and its assembly method. Background Technology

[0002] Prefabricated swimming pools are an innovative type of steel structure swimming pool that uses industrialized assembly lines to flexibly assemble and disassemble components. Some or all of the pool's components are prefabricated in a factory, then transported to the construction site, where they are assembled using reliable connection methods to form a complete pool. Prefabricated swimming pools are produced on a large scale in factories, ensuring controllable quality and precision, and minimizing material waste. At the same time, the industrialization of prefabricated swimming pools significantly improves labor productivity, allows for controllable progress, reduces on-site work, and eliminates dust, noise, and wastewater pollution, as well as the large amounts of construction waste generated by secondary renovations. Therefore, they are widely used in various recreational and training settings.

[0003] Because prefabricated swimming pools are assembled from multiple components, the joints between these components require high levels of waterproofing and leakage prevention. This makes the manufacturing and assembly of prefabricated swimming pools more difficult, which affects their use and development. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a prefabricated swimming pool and its assembly method, so as to solve the problem that the joints of the components of the prefabricated swimming pool in the prior art are difficult to assemble in order to avoid water leakage.

[0005] To achieve the above objectives, the present invention provides a prefabricated swimming pool, comprising two end pool bodies located at opposite ends, and further comprising:

[0006] At least one intermediate pool body, the two ends of which are respectively connected to the two end pool bodies;

[0007] The bottom base is used to support the end pool and the intermediate pool, and at least a portion of the bottom base is provided with an overflow trough;

[0008] The intermediate pool and any of the end pools can jointly form an injection channel, which is connected to the overflow tank. The injection channel is used to inject an adhesive medium to bond the intermediate pool, the end pool, and the tank bottom substrate together.

[0009] Furthermore, the overflow trough is an annular trough arranged circumferentially along the bottom substrate of the trough, and the end pool and the middle pool are configured to block the opening of the overflow trough.

[0010] Furthermore, the end face of the end pool body used to connect to the intermediate pool body is connected to a first mating member, and the end face of the intermediate pool body used to connect to the end pool body is connected to a second mating member, and the first mating member and the second mating member are inserted and sealed together.

[0011] Furthermore, the first mating component is constructed with a positioning post protruding from the engagement end face of the end pool body, and the second mating component is constructed with a positioning groove protruding from the engagement end face of the intermediate pool body. The first mating component and the second mating component are connected by the insertion and engagement of the positioning post and the positioning groove.

[0012] Furthermore, the end pool body includes a first support frame and a first support plate disposed on the inner and outer sides of the first support frame, and the middle pool body includes a second support frame and a second support plate disposed on the inner and outer sides of the second support frame;

[0013] The first support frame and the second support frame are hollow grid-like frames.

[0014] Furthermore, the first support frame includes: a plurality of vertically arranged perforated keels, and a plurality of rows of support rods respectively passing through the perforations of the perforated keels, and the first support plate is laid on the support rods and the perforated keels.

[0015] Furthermore, the intermediate pool has at least two connected end to end.

[0016] Furthermore, it also includes a crimping member, which is fixed at the opening of the infusion channel to compress the adhesive medium and seal the infusion channel.

[0017] Furthermore, a reinforcing support is fixed at the corner position of any of the said end pool bodies.

[0018] Furthermore, the present invention also provides an assembly method for a prefabricated swimming pool, applicable to prefabricated swimming pools as described in any of the preceding claims, comprising the following steps:

[0019] Support the bottom base of the trench;

[0020] Connect the end pool and the middle pool;

[0021] The connected end pool and intermediate pool are supported on the bottom base of the tank, and the bottom end face of the end pool and intermediate pool completely covers the overflow tank of the bottom base.

[0022] Inject adhesive medium into the injection channel until the injection channel is full;

[0023] Block the injection channel.

[0024] As can be seen from the above, the prefabricated swimming pool provided by the present invention has a bottom base with an overflow trough. Since the joint between the intermediate pool and any of the end pools can form an injection channel that extends to the overflow trough, by pouring an adhesive medium into the injection channel, the adhesive medium is located between the bottom base, the end pools, and the intermediate pool, thereby filling the joints of the bottom base, the end pools, and the intermediate pool with the adhesive medium, eliminating the connection gaps between the components, and effectively enhancing the sealing effect. In addition, the method of pouring the adhesive medium is simple and convenient to operate, effectively reducing the process difficulty. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0041] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0042] This embodiment provides a prefabricated swimming pool, including two end pools 1 located at the head and tail ends, at least one intermediate pool 2, and a bottom base 3. Each component can be prefabricated in the factory and transported to the assembly site for assembly. The mass production of each component makes the quality and dimensional accuracy of each component controllable, which can greatly reduce material waste and improve the convenience of transportation and assembly.

[0043] like Figures 1 to 3As shown, in the prefabricated swimming pool provided in this embodiment, the two ends of the intermediate pool 2 are respectively connected to the two end pools 1; the bottom base 3 is used to support the end pools 1 and the intermediate pool 2, and at least a portion of the bottom base 3 is provided with an overflow trough 31; wherein, the joint end of the intermediate pool 2 and any of the end pools 1 can jointly form an injection channel 4, the injection channel 4 is connected to the overflow trough 31, and the injection channel 4 is used to inject an adhesive medium so that the intermediate pool 2, the end pools 1 and the bottom base 3 are bonded together to form a whole.

[0044] As can be seen from the above description, in this embodiment of the prefabricated swimming pool, since the joint end of the intermediate pool body 2 and any of the end pool bodies 1 can form an injection channel 4 that extends to the overflow tank 31, by pouring an adhesive medium into the injection channel 4, the adhesive medium is located between the bottom substrate 3, the end pool body 1 and the intermediate pool body 2, thereby filling the joint parts of the bottom substrate 3, the end pool body 1 and the intermediate pool body 2 with the adhesive medium, eliminating the connection gaps between the components and effectively enhancing the sealing effect; in addition, the method of pouring adhesive medium is simple and convenient to operate, effectively reducing the process difficulty.

[0045] It should be noted that the bonding medium in this embodiment can be an existing mature adhesive, such as polyurethane foam or PUI adhesive (polyurethane polyimide adhesive). The adhesive can be directly injected into the injection channel using a glue gun. The adhesive will cure after a certain period of time to form a bond to the end pool 1, the middle pool 2 and the bottom substrate 3.

[0046] In some embodiments, the bottom substrate 3 is specifically a flat waterproof board, which can be laid directly on the ground or placed in the bottom of a pit after digging a pit in the ground. It should be noted that in this embodiment, directional terms such as "upper," "lower," "inner," and "outer" are all used with reference to the swimming pool in the figure, that is, the opening direction of the swimming pool is upper, the bottom of the swimming pool is lower, and the water storage space of the swimming pool is inner.

[0047] In some embodiments, such as Figure 2 As shown, the overflow trough 31 is an annular trough arranged circumferentially along the bottom base 3, with the end pool 1 and the middle pool 2 sealing the opening of the overflow trough 31. Specifically, the overflow trough 31 has a gradually narrowing opening at the end. The gradually narrowing opening can prevent glue leakage during injection and also enhance the fit and engagement effect with subsequent pressing components.

[0048] In some embodiments, the overflow trough 31 can also be discontinuously located on the bottom substrate 3, as long as the overflow trough 31 is provided between the joint of the end pool 1 and the middle pool 2; as an alternative implementation, the bottom substrate 3 itself does not have a flat plate, but is a frame-type substrate with only the overflow trough 31, as long as the overflow trough 31 can abut against the end pool 1 and the middle pool 2. When a frame-type substrate structure is adopted, the hollow part of the frame-type substrate can be filled with building fillers such as cement on site, thereby forming a flat waterproof plate fixed to the ground.

[0049] like Figure 4 As shown, in some embodiments, the end pool 1 consists of a bottom and three side sections, and its open ends corresponding to the three side sections are the connecting ends for connecting the intermediate pool 2. The two end pools 1 at both ends have the same structure. Specifically, the end pool 1 includes a first support frame and a first support plate 13 disposed on the inner and outer sides of the first support frame. The intermediate pool 2 includes a second support frame 25 and a second support plate 24 disposed on the inner and outer sides of the second support frame 25. The first support frame and the second support frame 25 are hollow grid-like frames.

[0050] Specific examples Figures 4 to 6 As shown, the first support frame includes several vertically arranged columns of perforated keels 11 and several rows of support rods 12 that pass through the perforations 111 of the perforated keels 11. The first support plate 13 is laid on the support rods 12 and the perforated keels 11. Both the perforated keels 11 and the support rods 12 can be made of high-strength metal materials. The support rods 12 are preferably made of aluminum alloy rectangular tubing. The perforated keels 11 have multiple perforations 111 along their length. The same support rod 12 passes through coaxially arranged perforations 111 on different columns of perforated keels 11; that is, the number of perforations 111 on the perforated keels 11 is the same as the number of rows of support rods 12. By forming a grid-like frame by passing support rods 12 through the perforated keels 11, the overall weight of the sheet metal can be reduced as much as possible while ensuring structural strength, which is beneficial for transportation and manufacturing.

[0051] In the above embodiment, the first support plate 13 located on both the inner and outer sides of the first support frame can be made of existing mature inorganic silicon refractory board. Inorganic silicon refractory board is lightweight, has high mechanical strength, and has good fireproof and waterproof performance, which can meet the daily needs of swimming pools. Of course, the first support plate 13 can also be made of other high-performance materials, such as fiberglass ceramic board. The first support plate 13 can be fixed to the first support frame by bonding, or by embedded snap-fit ​​or hidden screws. This embodiment does not make an absolute limitation on this.

[0052] As can be seen from the above description, the end pool 1 formed by the combination of the first support plate 13 and the first support frame is a hollow structure. The hollow structure can reduce the overall weight and is conducive to improving the heat preservation effect.

[0053] It should be noted that, as Figure 7 As shown, in some embodiments, the structure of the intermediate pool 2 can be assembled with reference to the structure of the end pool 1, that is, the first support frame and the second support frame 25 have the same structure, and the first support plate 13 and the second support plate 24 have the same material and connection method; as an alternative implementation, the intermediate pool 2 can also adopt other structures with good waterproof performance in the prior art.

[0054] like Figure 4 and Figure 8 As shown, in some embodiments, the end face of the end pool 1, which is used to connect to the intermediate pool 2, is connected to a first mating member 14, and the end face of the intermediate pool 2, which is used to connect to the end pool 1, is connected to a second mating member 21. The first mating member 14 and the second mating member 21 are connected by insertion and sealing.

[0055] The specifics are still as follows Figure 8 As shown, the first mating part 14 is a non-perforated strip plate connected to the first support frame. The length of the first mating part 14 is adapted to the depth of the end pool 1, and it is fixed to the joint end face of the end pool 1 by means of adhesive or screws. Here, the first mating part 14 has a female groove 15 with an outward opening. The second mating part 21 is a non-perforated strip plate connected to the second support frame 25. The length of the second mating part 21 is adapted to the depth of the end pool 1, and it is fixed to the joint end face of the end pool 1 by means of adhesive or screws. Here, the second mating part 21 has a female groove 22 with an outward opening. After the female groove 15 and the female groove 22 are inserted, a gap fit is formed to form a filling channel. Here, the gap fit between the female groove 15 and the female groove 22 facilitates the subsequent filling of the channel with adhesive medium. After the adhesive medium is filled into the channel, the female groove 15 and the female groove 22 can be deformed and expanded by the pressure of the pressing member 41, which is conducive to filling the adhesive medium.

[0056] As an alternative implementation, the insertion fit between the female groove 15 and the female groove 22 can be an interference fit, that is, the opening diameter of the female groove 22 is slightly smaller than the opening diameter of the female groove 15, the female groove 22 is inserted into the opening of the female groove 15, and at least part of the female groove 22 and the female groove 15 overlap. This arrangement can minimize the leakage of the adhesive medium, thereby helping to ensure the sealing of the injection channel. In some embodiments, the female groove 15 can be connected to the first mating member 14 by a separate connecting rod, or the first mating member 14 can be formed by a direct bending structure; the female groove 22 can be connected to the second mating member 21 by a separate connecting rod, or the second mating member 21 can be formed by a direct bending structure.

[0057] Furthermore, such as Figure 3 As shown, in some embodiments, the first mating member 14 is constructed with a positioning post 16 protruding from the joint end face of the end pool body 1, and the second mating member 21 is constructed with a positioning groove 23 protruding from the joint end face of the intermediate pool body 2. The first mating member 14 and the second mating member 21 are connected by the insertion and engagement of the positioning post 16 and the positioning groove 23. Here, the arrow direction is the direction from the inside to the outside of the swimming pool, which is the impact direction of the water flow. The positioning post 16 is set perpendicular to the joint end face of the end pool body 1. The positioning post 16 is inserted into the positioning groove 23, so that the joint part of the end pool body 1 and the intermediate pool body 2 forms a labyrinth seal. When the water flow in the swimming pool impacts the joint part of the end pool body 1 and the intermediate pool body 2, the insertion and engagement of the positioning post 16 and the positioning groove 23 can play a role in laterally blocking the water flow, thereby further improving the sealing effect of the end pool body 1 and the intermediate pool body 2.

[0058] In some embodiments, the bottom of the aforementioned positioning groove 23 is also provided with a sealing strip, and the positioning post 16 is inserted into the positioning groove 23 and abuts against the sealing strip to ensure a good anti-permeability sealing effect.

[0059] It should be noted that the aforementioned first mating part 14 can also be set on the intermediate pool body 2, and the second mating part 21 can be set on the end pool body 1. That is, the positions of the positioning post 16 and the positioning groove 23 can be interchanged between the end pool body 1 and the intermediate pool body 2.

[0060] In some embodiments, such as Figure 9As shown, after the connected intermediate pool 2 and end pool 1 form the injection channel 4, a pressing member 41 is provided at the opening of the injection channel 4. The pressing member 41 is used to seal the injection channel 4. Here, the pressing member 41 can be a flat material. The pressing member 41 is fixed to the injection channel 4 by interference deformation extrusion. The pressing member 41 can compress the adhesive medium located in the injection channel 4, thereby further increasing the retention density of the adhesive medium in the injection channel 4 and the overflow tank 31, so that the adhesive medium can better bond the end pool 1 and the intermediate pool 2. As an alternative implementation, the pressing member 41 can also be fixed to the injection channel 4 by clearance fit.

[0061] In some embodiments, the intermediate pool body 2 has two connected end to end, with a second mating member 21 provided at each end of each intermediate pool body 2. The two intermediate pool bodies 2 are connected by the insertion and mating of the second mating members 21, and the connected whole is then connected to the two end pool bodies 1. The intermediate pool bodies 2 can also be set to other numbers, which should be selected according to the length requirements of the swimming pool. It can also be seen that mass production of intermediate pool bodies 2 can flexibly select different numbers to build swimming pools of different sizes, thereby effectively improving the assembly flexibility of the swimming pool.

[0062] It should be noted that when multiple intermediate pools 2 are provided, an injection channel is formed between two adjacent intermediate pools 2 by the second mating part 21, and correspondingly, a pressing part 41 is also provided on the injection channel for sealing.

[0063] In some embodiments, a reinforcing support 5 is also fixed at the corner position of any end pool body 1. The cross-sectional shape of the reinforcing support 5 is right angled and it is attached to the corner position of the non-perforated keel. Since the swimming pool has a large load when it is filled with water, the reinforcing support 5 can prevent the support frame from deforming, thereby helping to protect the service life of the swimming pool.

[0064] In addition, this application also provides an assembly method for a prefabricated swimming pool, applicable to the prefabricated swimming pool described in any of the above embodiments, and includes the following steps:

[0065] 3. Lay the bottom base of the trench;

[0066] Connect the end pool 1 and the middle pool 2;

[0067] The connected end pool 1 and the middle pool 2 are supported on the bottom base 3 of the tank, and the bottom end faces of the end pool 1 and the middle pool 2 completely cover the overflow tank 31 of the bottom base 3.

[0068] Inject adhesive medium into injection channel 4 until it is full;

[0069] Block the injection channel 4.

[0070] In the above steps, the injection channel 4 can be sealed using the crimping member 41.

[0071] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of this disclosure (including the claims) is limited to these examples; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in the details for the sake of brevity.
