At present, my country's building insulation measures are mainly focused on internal and external walls, roofs, windows, etc., and less attention is paid to floor insulation. Insulated floors can effectively reduce the heat dissipation of the floor and improve the thermal insulation performance of the house. However, during the use of most of the insulation floors in the prior art, it is difficult for the insulation mortar to form a stable functional combination structure with the floor layer structure. At the same time, the floor itself has poor protection for the inner layer protective mortar, and the geology is hard. Cracks are prone to appear during long-term use, resulting in the failure of the inner layer insulation structure, which affects the normal function of the insulation floor and also reduces the overall service life of the floor.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figures 1 to 3The utility model provides a technical solution: a heat-insulating floor coating structure, including a nitrile rubber lining layer 1, a first steel mesh layer 2 is arranged at the bottom of the nitrile rubber lining layer 1, a first mortar layer 4 is filled in the first steel mesh layer 2, a first steel nail 5 with a matrix arrangement is arranged in the first mortar layer 4, a first steel mesh layer 2 is first laid on the foundation, and then the first steel nail 5 is inserted into the foundation, the top of the first steel nail 5 is located in the first steel mesh layer 2, and finally the first mortar layer 4 is injected into the first steel mesh layer 2, and the first mortar layer 4 is in a stable connection state with the foundation under the connection of the first steel nail 5 after solidification, and the nitrile rubber lining layer 1 is laid on the first mortar layer 4 after solidification. The top of the first steel nail 5 extends into the nitrile rubber lining layer 1, thereby improving the strength of the connection between the nitrile rubber lining layer 1 and the first mortar layer 4.

[0026] A first waterproof layer 6 is arranged on the upper surface of the nitrile rubber lining 1, and a first epoxy sealing layer 7 is arranged on the upper surface of the first waterproof layer 6. The first waterproof layer 6 and the first epoxy sealing layer 7 play the role of waterproofing and heat insulation.

[0027] A second steel mesh layer 8 is arranged on the upper surface of the first epoxy sealing layer 7, and a second mortar layer 9 is filled in the second steel mesh layer 8. The second mortar layer 9 and the first mortar layer 4 play the role of heat preservation on both sides. A second epoxy sealing layer 101 is arranged on the upper surface of the second mortar layer 9, and an epoxy putty layer 102 is arranged on the upper surface of the second epoxy sealing layer 101. A second waterproof layer 103 is arranged on the upper surface of the epoxy putty layer 102, and a topcoat layer 104 is arranged on the upper surface of the second waterproof layer 103. The second waterproof layer 103 is located between the topcoat layer 104 and the epoxy putty layer 102, which can effectively prevent moisture from entering the topcoat layer 104 and corroding the epoxy putty layer 102, so that the topcoat layer 104 is not easy to fall off, and the anti-cracking performance of the topcoat layer 104 is improved.

[0028] Furthermore, the first steel mesh layer 2 is connected to the second steel mesh layer 8 through an expansion joint 106. The function of the expansion joint 106 is to strongly connect the first steel mesh layer 2 and the second steel mesh layer 8, that is, the expansion joint 106 uses its expansion characteristics to be connected to the first steel mesh layer 2 and the second steel mesh layer 8 respectively. When in use, the expansion joint 106 is connected to the first steel mesh layer 2 and the second steel mesh layer 8 in a lattice manner. This arrangement prevents the second steel mesh layer 8 from moving and shifting when pouring the second mortar layer 9, so that the second steel mesh layer 8 is evenly distributed in the second mortar layer 9, and can further improve the tightness of the connection between the second mortar layer 9 and the first mortar layer 4, thereby further improving the crack resistance of the coating.

[0029] Wherein, the first waterproof layer 6 and the second waterproof layer 103 are both PVC layers.

[0030] Furthermore, PET isolation films are provided on both the upper and lower sides of the first waterproof layer 6 and the second waterproof layer 103, that is, a PET isolation film is provided between the first waterproof layer 6 and the nitrile rubber lining layer 1 and the first epoxy sealing layer 7, and a PET isolation film is provided between the second waterproof layer 103 and the epoxy putty layer 102 and the topcoat layer 104, so as to further improve the waterproof performance.

[0031] In this embodiment, a second steel nail 105 distributed in a matrix is ​​connected between the first mortar layer 4 and the second mortar layer 9. This arrangement enables the first mortar layer 4 and the second mortar layer 9 to be in a fastened connection state after solidification, thereby improving the adhesion strength between the layers of the coating structure.

[0032] Furthermore, the spacing between adjacent second steel nails 105 distributed in the matrix is ​​100-150 mm. This spacing not only improves the connection strength of the first mortar layer 4 and the second mortar layer 9, but also is not easy to destroy the integrity of the first mortar layer 4 and the second mortar layer 9, that is, the first mortar layer 4 and the second mortar layer 9 are not easy to crack after curing.

[0033] In this embodiment, the thickness of the topcoat layer 104 is 1-1.5 mm. Since the epoxy putty layer 102 is waterproof, the topcoat layer 104 with this thickness can improve the waterproof performance and the strength against cracking.

[0034] In this embodiment, the expansion joint 106 includes a center column 1061 and a V-shaped elastic clip 1062 fixedly arranged around the center column 1061. The plane where the V-shaped elastic clip 1062 is located coincides with the axis of the center column 1061. Pads 10611 are fixedly sleeved at both ends of the center column 1061.

[0035] Furthermore, the number of V-shaped elastic clips 1062 is three and they are evenly distributed around the middle column 1061. The tip of the V-shaped elastic clip 1062 is welded to the outer wall of the middle column 1061, and the length of the middle column 1061 is smaller than the distance between the open ends of the V-shaped elastic clip 1062. When using the expansion joint 106, when laying the first steel mesh layer 2, the bottom of the middle column 1061 is inserted into the mesh of the first steel mesh layer 2, and the pad 10611 at the bottom of the middle column 1061 squeezes the first steel mesh layer 2, and at the same time bends the lower end of the V-shaped elastic clip 1062 to insert it into the mesh of the first steel mesh layer 2, and then uses the elastic force to hook the first steel mesh layer 2, and then pour the first mortar layer 4, and when the second steel mesh layer 8 is subsequently installed, the top of the expansion joint 106 connected to the first steel mesh layer 2 is connected to the second steel mesh layer 8 in the same way.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
