Description

Swimming pool made of polypropylene, containing the bottom, walls and collar

Field of technology

The technical solution relates to a polypropylene pool containing a bottom, walls and a collar.

Prior art

Existing polypropylene pools have a bottom, walls and a collar. The walls are provided with ribs on the outside.

The bottom and shell of the pool are usually made of polypropylene boards with a thickness of 5, 6, or 8 mm. The collar and ribs of the pool are usually made of polypropylene with a thickness of 15 mm. The pool ribs are placed in straight sections of the pool shell with a maximum spacing of 750 mm. 20 ribs are used in the pool measuring 3 x 6 x 1.5 m. The weight of the rib material is approximately 47 kg. The ribs are welded to the bottom, mantle and collar. The total length of the welds of the ribs of the above-mentioned pool is 68 m. After making the basic shape, thermal insulation in the form of polystyrene boards is applied to the pool shell between the individual ribs. The polystyrene boards are attached with binding tape.

The pool with polypropylene ribs and insulation from expanded polystyrene boards, after being placed on the base plate at the place of implementation, must be surrounded by a system of lost formwork. The lost formwork must be firmly connected to the reinforced concrete foundation slab. Lost formwork serves as a soil support, preventing the transmission of ambient pressure to the pool walls. Concreting of a separate polypropylene pool is performed with semi-dry concrete. Concrete is poured between the wall of the pool shell with thermal insulation and the lining of the lost formwork. The concrete backfill of the pool has only a filling function.

The time required for the subsequent construction work of the pool production after the installation of the pool on the base plate is about 8 days. The works should follow in the following order:

- Day 1 - concreting of lost formwork,

- 2nd and 3rd day technological break,

- Day 4 concreting of the pool fill up to a height of 30 cm,

- Day 5 concreting of the pool fill up to a height of 60 cm,

- Day 6 concreting of the pool fill up to a height of 90 cm,

- Day 7 concreting of the pool fill up to a height of 120 cm,

- Day 8 final concreting of the pool to the amount of the future surface treatment, ie paving, etc., anchoring of the pool collar with reinforcing steel rods.

The essence of the technical solution

The above drawbacks are largely eliminated by a polypropylene pool comprising a bottom, walls and a collar, according to this technical solution. Its essence is that its walls are without ribs and are provided on the outside with thermal insulation boards with a thickness of at least 100 mm. The thermal insulation boards are glued to the pool wall and / or tightened with a cable tie.

The slabs are preferably provided with vertical through holes for accommodating metal reinforcement and / or concrete grout.

The corners of the pool are preferably provided with rounded plates, copying the outer roundness of the pool.

The essence of the technical solution is the replacement of ribbing and insulation of the pool with polystyrene thermal insulation boards, which can also be in the form of pouring blocks. The essence of the new construction of the plastic pool lies in the replacement of the vertical ribs of the pool and the board polystyrene insulation with thermal insulation blocks, which can be pouring. The blocks can be glued to the plastic skeleton, or just attached and fixed, ie secured with a cable tie. Each is fixed with tape

-1 CZ 30142 UI series of polystyrene blocks. By installing the skeleton of the blocks, the production times associated with the assembly of the ribs and with the insulation of the walls with polystyrene board are achieved. At the same time, the overflow blocks replace the recommended pool wall with lost formwork.

After settling on the base plate of the pool, the pool with pouring blocks no longer has to be walled, but only the blocks are poured with concrete. Polystyrene blocks can be reinforced with steel fittings, both horizontally and vertically. The vertical reinforcement is firmly connected to the base plate of the pool and at the same time extends into the future layer of the concrete wreath, which is a phenomenon in place of the plastic collar of the pool. The connection of the vertical reinforcement to the base plate is made by means of pre-formed grooves in the base plate. The ends of the vertical reinforcements are inserted into the grooves, which are located around the entire perimeter of the pool and connect to the cavities in the polystyrene blocks. The grooves in the base plate have a cross section of 100x100 mm. After pouring the pouring blocks with concrete, it fills the concrete and the grooves in the foundation slab, thus connecting the foundation slab and the polystyrene pouring blocks. It is enough to cover the concreted pool with soil, which will be adequately compacted. By using a pool design surrounded by polystyrene insulation pouring blocks, the following improvements and savings are achieved.

The material and time of production of vertical ribs is saved, for a pool measuring 3 x 6 x 1.5 m it is about 47 kg of polypropylene, and 68 m of weld and the related production time in the workshop. Furthermore, the material of the pool lining from the lost formwork and the material of the concrete backfill of the pool will be saved.

It also saves total construction time. By removing the lining and concrete backfill, the construction of the pool will be halved. Another advantage is the improvement of the thermal insulation of the pool walls compared to a pool with vertical ribs. The polystyrene insulation blocks adhere to the casing without interrupting the ribs, thus removing the thermal bridges that formed the ribs of the pool.

As a result, this pool construction is cheaper with a shorter construction time and at the same time the pool has better insulating properties than the standard design with ribs and insulation made of polystyrene board.

Examples of technical solution

An exemplary polypropylene pool comprising a bottom 1, walls 2 and a collar 3 has ribless walls 2 provided on the outside with thermal insulation boards 4 with a thickness of 100 mm, which are fastened to the pool wall 2 with a cable tie 5. The pool corners are provided with rounded boards 4, copying the outer roundness of the pool.

In another embodiment, the walls 2 of the pool without ribs are provided on the outside of the pool with glued thermal insulation boards 4 in the form of blocks with a thickness of 250 mm. The blocks are provided with vertical through holes 6 for locating the metal reinforcement 7 and the concrete grout. The rounded corners of the pool are left free and the space created is filled with thermal insulation filling during installation.

In another embodiment, the tiling in the straight walls of the boards 4 is continued until they meet, i.e. the intersection, when they join to form a stable element and the free space behind them towards the rounded corner of the pool remains free - the rounded corner is carried out by itself, or is filled with polystyrene, etc.

By fitting the skeleton with boards 4 from the pouring blocks, the production times associated with the assembly of the ribs and the insulation of the walls with polystyrene board are achieved. At the same time, the blocks replace the recommended pool lining with lost formwork. The pool with overflow blocks after settling on the foundation

-2GB 30142 The pool UI board 8 no longer has to be walled in, but only the blocks are filled with concrete. The polystyrene blocks are reinforced with steel reinforcement 7, both horizontally and vertically. The horizontal steel reinforcement 7 can be replaced by so-called wire concrete. The vertical reinforcement 7 is firmly connected to the base plate 8 of the pool and at the same time extends into the future layer of the concrete wreath 9, which is in place of the plastic collar 3 of the pool. Prior to concreting the wreath 9 around the pool, holes are drilled around the perimeter of the plastic collar 3 through which the reinforcing reinforcement 7 is passed. the position of the upper part of the pool is permanently ensured. The concrete concreted in this way just needs to be covered with soil, which will be adequately compacted.

Industrial applicability

The pool according to this technical solution will find application mainly in pools for recreational purposes.
