Technical Field
[0001] This application relates to the field of building engineering technology, specifically to an insulated floor with waterproof settlement joints. Background Technology
[0002] Settlement joints are vertical joints designed to prevent damage to buildings caused by uneven settlement of the foundation. They are frequently installed in the ground structures of various buildings.
[0003] As a type of floor structure with excellent thermal insulation properties, insulated flooring requires consideration of ground structure settlement during construction, especially for large areas. However, the presence of settlement joints in insulated flooring disrupts the overall continuity of the floor, providing pathways for moisture penetration. Improper waterproofing can allow moisture to seep in through these settlement joints, leading to dampness in the subfloor, insulation material failure, and even compromising the structural safety and lifespan of the building.
[0004] Therefore, how to design an insulated floor with waterproof settlement joints has become an urgent problem to be solved in this field. Summary of the Invention

[0038] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.
[0039] This application provides an insulated floor with waterproof settlement joints, such as... Figure 1-2 As shown, the insulated floor first comprises: a settlement joint 10, a concrete layer 20, an insulation layer 30, and a waterproof layer 1. The insulation layer 30 is sandwiched within the concrete layer 20 to provide thermal insulation. The waterproof layer 1 is positioned between the insulation layer 30 and the concrete layer 20 to provide waterproofing for the insulation layer 30.
[0040] The concrete layer 20, being a rigid structure, needs to be interrupted at the settlement joint 10 to prevent cracking due to internal stress. That is, the settlement joint 10 penetrates the concrete layer 20 to provide deformation capacity. The waterproof layer 1 and the insulation layer, being integrally flexible or partially flexible structures, do not need to be interrupted at the settlement joint 10, utilizing their flexible structure to provide deformation capacity. That is, the settlement joint 10 penetrates both the waterproof layer 1 and the insulation layer 30. The waterproof layer 1 is an integrally flexible continuous structure. The insulation layer 30 is a partially flexible continuous structure, including a flexible insulation structure 31. The location of this flexible insulation structure 31 corresponds to the location of the settlement joint 10, so that the insulation layer 30 has deformation in the extension direction of the settlement joint 10.
[0041] Meanwhile, to ensure the deformability of the waterproof layer 1 and prevent it from bearing local stress at the settlement joint 10, the insulated floor provided in this application also includes a gap support structure 2. The gap support structure 2 is installed at the waterproof layer 1 in the settlement joint 10 to provide reserved space for the waterproof layer 1 at the settlement joint 10, so that the waterproof layer 1 can deform at the settlement joint 10.
[0042] Regarding the specific structure of the insulation layer 30, the insulation layer 30 in this application includes two types of insulation materials: a flexible insulation structure 31 and a rigid insulation structure 32. The flexible insulation structure 31 has a V-shaped structure and is set within the rigid insulation structure 32. The two are staggered and interlocked, and the central settlement joint 10 of the flexible insulation structure 31 is aligned with the settlement joint 10. This flexible insulation structure 31 can deform along with both sides of the settlement joint 10, preventing the rigid insulation material 32 within the insulation layer 30 from breaking under ground stress, thus affecting the insulation effect of the ground. In other words, this application uses the flexible insulation structure 31 to absorb the settlement deformation occurring at the settlement joint 10, while the rigid insulation structure 32 ensures the insulation effect at the settlement joint 10.
[0043] In one specific embodiment, the flexible insulation structure 31 is made of pixel sponge, and the rigid insulation structure 32 is made of extruded polystyrene board with a compressive strength ≥300kPa.
[0044] Regarding the structural relationship between the concrete layer 20 and other layers, the concrete layer 20 of this application includes, from top to bottom, the following layers: concrete surface layer 21, concrete inner layer 22, and concrete base layer 23.
[0045] In one specific embodiment, the thermal insulation layer 30 is disposed between the concrete surface layer 21 and the concrete inner layer 22, and the waterproof layer 1 is disposed between the concrete surface layer 21 and the thermal insulation layer 30, and between the concrete inner layer 22 and the concrete base layer 23. That is, waterproof layers are provided on both sides of the thermal insulation layer 30 to prevent water from the concrete base layer 23 and water from the concrete surface layer 21 from seeping into the thermal insulation layer 30. Of course, since the waterproof layer 1 is a continuous structure, it needs to avoid the gap support structure 2 at the settlement joint 10.
[0046] Waterproof layer 1 can be made of waterproof membrane, such as asphalt, rubber, synthetic resin, etc.; or, waterproof layer 1 can also be made of building waterproof coating, such as polyurethane, acrylic, etc.
[0047] To provide basic protection for the settlement joint 10, the insulated ground in this application also includes a cover plate 3, which is placed on the surface of the concrete surface layer 21 and covers the opening of the settlement joint 10 to prevent the settlement joint 10 from coming into direct contact with water.
[0048] In one specific embodiment, the cover plate 3 is an inverted U-shape, made of stainless steel, and is fastened to the concrete surface layer 21 for fixation.
[0049] To prevent water from seeping downwards from the concrete surface layer 21 and causing the concrete surface layer 21 to freeze and expand in a low-temperature environment, resulting in excessive local stress and cracking of the concrete, the thermal insulation floor in this application also includes a waterstop 4, which is set in the concrete surface layer 21 and has gaps at the settlement joint 10.
[0050] In one specific implementation, the waterstop 4 is a rubber waterstop that extends from the settlement joint 10 to both sides in the concrete surface layer 21, and its specific extension length can be adjusted as needed.
[0051] To further isolate moisture, the insulated floor in this application also includes a vapor barrier layer 5. This vapor barrier layer 5 is positioned between the waterproof layer 1 and the insulation layer 30, and like the waterproof layer 1, it is a flexible material, forming a continuous structure at the settlement joint 10. Simultaneously, a gap support structure 2 is also provided at the vapor barrier layer 5 within the settlement joint 10 to allow for deformation of the vapor barrier layer 5 at the settlement joint 10, ensuring sufficient length of the vapor barrier layer 5 at the settlement joint 10.
[0052] In one specific embodiment, the vapor barrier 5 is disposed between the first waterproof layer 1 and the insulation layer 30, and between the insulation layer 30 and the inner concrete layer 22. Of course, since the vapor barrier 5 is also a continuous structure, it is necessary to avoid the gap support structure 2 at the settlement joint 10. The vapor barrier 5 can be a vapor barrier membrane, such as an ethylene film or a polyvinyl chloride film.
[0053] The gap support structure 2 set at the vapor barrier 5 and the waterproof layer 1 can be a flexible support rod made of pixel sponge with strong deformation capacity, which can release the reserved length of flexible material at the settlement joint 10; or, a rigid support rod can be set at the waterproof layer 1 and the vapor barrier 5 in the settlement joint 10 first, and then the rigid support rod can be removed after the waterproof layer 1 and the vapor barrier 5 are completed to form the gap support structure 2, which can also release the reserved length of flexible material at the settlement joint 10.
[0054] To further seal off moisture, the gaps in the settlement joint 10 of this application are filled with sealant to enhance the waterproofing capability of the settlement joint 10.
[0055] In one specific embodiment, the settlement joint 10 between the concrete surface layer 21 and the insulation layer 30, that is, the settlement joint 10 above the insulation layer 30, is filled with a first sealant 6, the material of which is silicone weather-resistant sealant; while the settlement joint 10 between the concrete inner layer 22 and the insulation layer 30, that is, the settlement joint 10 below the insulation layer 30, is filled with a second sealant 7, the material of which is low-temperature resistant asphalt putty.
[0056] In one specific embodiment, the insulated floor with waterproof settlement joints provided in this application comprises, from top to bottom: an asphalt layer 40, a concrete surface layer 21, a first waterproof layer 1, a first vapor barrier 5, an insulation layer 30, a second vapor barrier 5, a concrete inner layer 22, a second waterproof layer 1, and a concrete base layer 23. The asphalt layer 40, the first waterproof layer 1, the first vapor barrier 5, the insulation layer 30, the second vapor barrier 5, and the second waterproof layer 1 form a continuous structure, without interruption at the settlement joint 10. The settlement joint 10 penetrates the concrete surface layer 21, the concrete inner layer 22, and the concrete base layer 23. Above the concrete base layer 23, the settlement joint 10 is a waterproof settlement joint, and the settlement joint in the concrete base layer 23 is a ground foundation settlement joint.
[0057] This application provides an insulated floor with waterproof settlement joints. Settlement joints are set in the concrete layer of the insulated floor, a flexible material structure is set in the insulation layer of the insulated floor, and a waterproof layer is set between the insulation layer and the concrete layer. At the same time, a gap support structure is set at the waterproof layer in the settlement joint, so that the insulated floor can absorb the deformation caused by ground settlement, ensuring the structural safety of the insulated floor, while improving the insulation, waterproof and vapor barrier functions of the insulated floor, and extending the service life of the insulated floor.
