The utility model provides a technical scheme that its technical problem adopted is:
child action ground floor layer with buffering safeguard function, including basic unit, high-elastic ETPU granule and EPDM supporting layer, the basic unit is inlayed and is had high-elastic ETPU granule, the top of high-elastic ETPU granule is equipped with the EPDM supporting layer.
Preferably, the base layer is formed by paving two-component polyurethane slurry.
Preferably, the thickness of the base layer is 5-8 mm.
Preferably, the high-elasticity ETPU particles are polyether TPU particles, the particle size is 5-6mm, and the density is 0.1-0.2g/cm3。
Preferably, the EPDM support layer has an average thickness of 3 to 5 mm.
Preferably, the EPDM support layer is formed by mixing and spreading a polyurethane adhesive and Ethylene Propylene Diene Monomer (EPDM) particles with the particle size of 1-2 mm.
The high-elastic ETPU particles in the utility model play a role of buffering the main body; the EPDM supporting layer that the top layer was equipped with has certain intensity, provides the activity and supports.
The ground foundation of the foundation layer of the ground layer of the child playground can be a cement concrete foundation or an asphalt foundation, when in construction, the cement foundation needs to be firstly coated with a layer of polyurethane adhesive in a rolling way, and the asphalt foundation firstly scrapes a layer of bi-component polyurethane slurry for bonding the foundation layer and the ground foundation.
The construction process is as follows:
firstly, laying bi-component polyurethane slurry, after leveling, uniformly embedding high-elasticity ETPU particles on the surface of a base layer before gelation, and leveling; and removing the high-elasticity ETPU particles which are not bonded on the surface after the base layer is cured, uniformly spreading the EPDM particles and the single-component polyurethane adhesive which are uniformly mixed on the high-elasticity ETPU particles, and during spreading, paying attention to the fact that the gaps among the high-elasticity ETPU particles are filled with the mixed material of the EPDM particles and the single-component polyurethane adhesive, and the surface layer is flat.
The materials designed in the present invention are well known to those skilled in the art.
The utility model discloses the beneficial effect who has is:
the utility model discloses well basic layer is inlayed and is had high-elastic ETPU granule, plays the main part cushioning effect, and the top layer is equipped with the EPDM supporting layer of certain intensity, provides the activity and supports. The utility model discloses combine the advantage in traditional mixed type and ventilative type activity place, have good buffering barrier propterty, be applicable to laying in all kinds of children's activity places such as children's amusement park, kindergarten.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a base layer; 2. high-elastic ETPU particles; 3. an EPDM support layer.
Detailed Description
Embodiments of the present invention are further described below with reference to the accompanying drawings:
example 1
As shown in fig. 1, the said buffer protection functionThe child playground floor layer comprises a base layer 1, high-elasticity ETPU particles 2 and an EPDM supporting layer 3, wherein the high-elasticity ETPU particles 2 are embedded in the base layer 1, and the EPDM supporting layer 3 is arranged above the high-elasticity ETPU particles 2; the base layer 1 is formed by paving double-component polyurethane slurry, and the whole thickness of the base layer 1 is 5 mm; the high-elasticity ETPU particles 2 are polyether TPU particles, the particle size is 6mm, and the density is 0.2g/cm3(ii) a The EPDM support layer 3 has an average thickness of 5 mm; the EPDM supporting layer 3 is formed by mixing and paving a polyurethane adhesive and EPDM rubber particles with the particle size of 1 mm.
The thickness of the whole floor layer of the child playground is 13 mm.
Taking asphalt ground as an example, the construction process is as follows:
firstly, laying bi-component polyurethane slurry, after leveling, uniformly embedding high-elasticity ETPU particles 2 on the surface of a base layer 1 before gelation, and leveling; after the base layer 1 is cured, removing the high-elasticity ETPU particles 2 which are not bonded on the surface, uniformly spreading the EPDM particles and the single-component polyurethane adhesive which are uniformly mixed on the high-elasticity ETPU particles 2, and during spreading, paying attention to the fact that the gaps among the high-elasticity ETPU particles 2 are filled with the mixed material of the EPDM particles and the single-component polyurethane adhesive, and the surface layer is flat.
Example 2
As shown in fig. 1, the other structures of the floor layer with a buffering and protection function for a child playground are the same as those of embodiment 1, except that:
the overall thickness of the base layer 1 is 8 mm;
the particle diameter of the high-elastic ETPU particles 2 is 5mm, and the density is 0.1g/cm3；
The EPDM support layer 3 has an average thickness of 3 mm;
the EPDM supporting layer 3 is formed by mixing and paving a polyurethane adhesive and EPDM rubber particles with the particle size of 2 mm.
The thickness of the whole floor layer of the child playground is 12.5 mm.
Taking a cement base as an example:
