Detailed Description

The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, in order to provide an assembled shock-absorbing impact-resistant floor disclosed in the embodiments of the present application, the floor is mainly composed of arigid bottom layer 11, abase 12, a floatingseat 14, anelastic cushion 15, a connectingrib 16, arigid interlayer 17, an elasticfilling material layer 18, and the like, specifically, therigid bottom layer 11 is used for laying on the floor in a room, and in some possible implementation manners, wet paving (sand and gravel plus cement plus glue) may be used for laying.

Referring to fig. 2 and 3, therigid substrate 11 haspedestals 12 uniformly distributed thereon, and thepedestals 12 are used for supporting the floatingseat 14. Thepedestals 12 are arranged on therigid bottom layer 11 in a matrix of MxN, M and N are both natural numbers greater than zero, and the stressed pressure can be uniformly dispersed by densely arranging thepedestals 12.

Eachbase 12 is provided with anelastic cavity 13, anelastic cushion 15 is placed in theelastic cavity 13, and in some possible implementations, theelastic cushion 15 is bonded in theelastic cavity 13 by using glue. Thefloating seat 14 has a first end extending into theelastic cavity 13 and abutting against theelastic cushion 15, and a second end extending from theelastic cavity 13 and abutting against therigid partition 17.

A gap exists between therigid spacer layer 17 and therigid bottom layer 11, the gap is generated by the support of thebase 12, thefloating seat 14 and theelastic cushion 15, the gap is filled by the elasticfilling material layer 18, so that a part of the pressure applied to therigid spacer layer 17 can be born by thefilling material layer 18, and the deformation of therigid spacer layer 17 is absorbed by the deformation of thefilling material layer 18 to avoid being transmitted to therigid bottom layer 11.

Thebases 12 are also connected by connectingribs 16 to form a whole, and in the case of the above-mentioned arrangement of thebases 12 in a matrix of MxN on therigid substrate 11, eachbase 12 is connected to anadjacent base 12 by short bars, thebases 12 at the corners are connected to twoadjacent bases 12, thebases 12 at the edges are connected to threeadjacent bases 12, and thebases 12 in the middle are connected to fouradjacent bases 12.

When a plurality ofbases 12 are connected together, a net structure can be formed, for example, a pressure applied to onebase 12 or abase 12 in a certain area can be transmitted toother bases 12 through the connectingribs 16, and assuming that the applied pressure value is 20, if the number ofbases 12 in the influence range is four, the pressure value borne by eachbase 12 is 5, and if the number ofbases 12 in the influence range can be increased to 20 through the connectingribs 16, the pressure value borne by eachbase 12 is 1.

From the point of view of use, thesingle base 12 bears less pressure, which means that the amount of deformation of theelastic cushion 15 is less, on the one hand, it reacts more rapidly, and on the other hand, it also extends the service life of theelastic cushion 15. From the use experience, the amount of deformation of the singleelastic cushion layer 15 is smaller, which means that it is less noticeable to the user, because too large an amount of deformation gives the user a feeling of soft bottom.

In addition, theelastic filler layer 18 can also bear a part of the pressure, since theelastic filler layer 18 also comes into contact with therigid barrier layer 17, and can thus absorb a part of the pressure to which therigid barrier layer 17 is subjected by deformation.

In summary, the assembled shock-absorbing impact-resistant floor provided by the embodiment of the present application supports therigid interlayer 17 through thebase 12, the floatingseat 14 and theelastic cushion 15 arranged in the matrix form, and this multi-point contact support manner can make the stress of therigid interlayer 17 uniform. This support also leaves a certain amount of space to accommodate the layer ofresilient filler material 18 so that the entire bottom surface of therigid barrier 17 is supported.

The support thatbase 12, floatingseat 14 andelastic cushion layer 15 provided belongs to hard supporting, and the support that elasticfilling material layer 18 provided belongs to soft supporting, and this kind of soft or hard support mode that combines can provide better supporting effect, has both avoided the poor problem of hard support elasticity, has also solved the not enough problem of soft support rigidity.

In addition, because thebases 12 are connected together by the connectingribs 16, local stress can be shared by thebases 12, thefloating bases 14 and theelastic cushion layer 15, the deformation degree of theelastic cushion layer 15 is reduced, and the supporting rigidity can be improved to a certain degree.

Referring to fig. 4 and 5, as a specific embodiment of the assembled shock-absorbing impact-resistant floor provided by the application, therigid partition 17 is provided with a connectinghole 171 on the bottom surface, the connectinghole 171 is used for assisting in fixing the floatingseat 14, that is, the second end of the floatingseat 14 can extend into the connectinghole 171, the connecting mode has two functions,

firstly, the installation is convenient, that is, in the installation process, a worker can directly lay therigid interlayer 17 on the floatingseat 14 and then slightly shake on the horizontal plane, and the second end of the floatingseat 14 can slide into the connectinghole 171.

Secondly, the fixing effect is better, after the second end of the floatingseat 14 is clamped into the connectinghole 171, a plurality of limits are generated on therigid interlayer 17 in the horizontal direction, and the limits can fundamentally avoid the displacement of therigid interlayer 17 on the horizontal plane.

Further, the sectional area of theconnection hole 171 tends to decrease in a direction away from the floatingseat 14.

Referring to fig. 2, as an embodiment of the fabricated shock-absorbing and impact-resisting floor provided by the present application, the rigidbottom layer 11 is integrally formed with thebase 12, so that the number of construction steps in the field installation process can be effectively reduced, because the rigidbottom layer 11 is laid on the ground after being integrally formed, and the position of thebase 12 is fixed.

Further, theelastic cushion 15 is directly adhered to theelastic chamber 13 of the base 12 during the manufacturing process.

Referring to fig. 2, as an embodiment of the fabricated shock-absorbing and impact-resisting floor provided by the present application, the connectingribs 16 are integrally formed with the rigidbottom layer 11, which is advantageous in that the thickness of the elasticfilling material layer 18 can be increased to some extent, and the noise reduction effect can be further improved.

It will be appreciated that both therigid substrate 11 and therigid spacer 17 require a certain thickness to ensure strength, but increasing the thickness increases the weight of therigid substrate 11 and therigid spacer 17. When the connectingribs 16 are made together with the rigidbottom layer 11, the connectingribs 16 can be regarded as a part of the rigidbottom layer 11, namely, a plurality of transverse and longitudinal connecting ribs are added on the rigidbottom layer 11, and the connecting ribs can play a role of improving the rigidbottom layer 11.

Under the condition of equivalent thickness, a plurality of pits are added on the rigidbottom layer 11, and the pits can accommodate the elasticfilling material layer 18, that is, more elastic fillingmaterial layers 18 can be accommodated between the rigidbottom layer 11 and therigid interlayer 17, and the better sound absorption and shock absorption effects can be improved.

Referring to fig. 6, as a specific embodiment of the fabricated shock-absorbing impact-resistant floor provided by the application, the floatingseats 14 on the same rigidbottom layer 11 are divided into at least two groups, and each group of floatingseats 14 is connected with onerigid interlayer 17, and the connection mode can enable the rigidbottom layer 11 to be connected with differentrigid interlayers 17, so that the connection stability can be improved.

Referring to fig. 6, as an embodiment of the assembled shock-absorbing and impact-resisting floor provided by the application, the samerigid interlayer 17 is connected to at least the floatingseats 14 belonging to two rigid bottom layers 11 in such a way that therigid interlayer 17 is connected to different rigid bottom layers 11, which can improve the stability of the connection.

Referring to fig. 4 and 5, as a specific embodiment of the assembled shock-absorbing and impact-resisting floor provided by the application, therigid partition 17 is provided with an injection throughhole 172, and the injection throughhole 172 is used for injecting an elastic filling material into a gap between therigid partition 17 and the rigidbottom layer 11.

It will be appreciated that if the layer ofresilient infill material 18 is produced in a prefabricated manner, the height of the layer ofresilient infill material 18 will be slightly less than the thickness of the floatingseat 14 in order to ensure the mounting effect, since it is ensured that the second end of the floatingseat 14 can be inserted into theattachment hole 171 in therigid partition 17 and fully contact the inner wall of theattachment hole 171, but this will also result in a gap between the layer ofresilient infill material 18 and the bottom surface of therigid partition 17.

When the elasticfilling material layer 18 is manufactured by injection, the second end of the floatingseat 14 can be ensured to be completely contacted with the inner wall of the connectinghole 171, and the elastic filling material can also completely fill the gap between the rigidbottom layer 11 and therigid interlayer 17.

The embodiment of the application also discloses an assembly type shock-absorbing impact-resistant ground installation method, which comprises the following steps:

s101, paving the rigidbottom layer 11 on the ground;

s102, placing theelastic cushion layer 15 in theelastic cavity 13 on thebase 12;

s103, laying therigid interlayer 17 on the rigidbottom layer 11, and inserting the second end of each floatingseat 14 into the connectinghole 171 on therigid interlayer 17;

s104, injecting an elastic filling material into a gap between therigid partition layer 17 and the rigidbottom layer 11 through the injection throughhole 172;

and S105, closing the injection throughhole 172 after the injection of the elastic filling material is finished.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
