Description

Technical Field

[0001] This utility model belongs to the field of roof waterproofing technology, specifically relating to a detachable thermal insulation and waterproof composite layer structure suitable for roof recycling. Background Technology

[0002] Roof insulation and waterproofing systems are crucial components of building energy conservation and leak prevention. Traditional roof insulation structures often use permanent bonding methods, stacking the insulation layer, airtight layer, and waterproofing layer sequentially and fixing them directly to the base layer. While this type of structure can provide good thermal insulation and waterproofing performance in the short term, it suffers from the following problems in long-term use: When partial roof repairs are needed, or the waterproofing layer ages or the insulation board performance deteriorates, the entire structure often needs to be removed, resulting in material waste and increased construction costs, and waste disposal is detrimental to environmental protection; Traditional roof systems are difficult to flexibly adjust during construction or maintenance phases due to different climatic conditions and roof structure changes, and cannot achieve modular replacement and reuse; Due to temperature and humidity changes, moisture or air accumulates inside the roof, and without an effective ventilation structure, the waterproofing layer may bulge or crack due to increased internal pressure. However, traditional ventilation holes without backflow prevention can cause rainwater to flow back in; Existing protective layers are mostly single-material structures, which are prone to cracking and wear when exposed to high temperatures, ultraviolet rays, wind, and rain for extended periods, affecting the lifespan of the waterproofing and insulation layers.

[0003] Therefore, there is an urgent need for a roof insulation and waterproofing composite layer structure that is detachable, easy to recycle, and takes into account airtightness, waterproofness, and ease of maintenance, so as to extend the service life of the roof, reduce maintenance costs, and improve environmental benefits. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a detachable thermal insulation and waterproof composite layer structure suitable for roof recycling, which can be recycled and extend the service life of the roof, reduce maintenance costs and improve environmental benefits.

[0005] The technical solution adopted by this utility model is a detachable thermal insulation and waterproof composite layer structure suitable for roof recycling, including a roof, the roof including a structural layer, a leveling layer attached to the structural layer, a thermal insulation board attached to the leveling layer, an airtight layer attached to the thermal insulation board, a protective layer attached to the airtight layer, and a waterproof layer attached to the protective layer.

[0006] The present invention is further characterized in that, The leveling layer has first interlocking blocks at both ends of the top and rear sides.

[0007] The bottom end of the insulation board is provided with a first fitting groove, which fits into the first fitting block. The top end of the insulation board is provided with a second fitting block.

[0008] The bottom of the airtight layer is provided with a second fitting groove at both ends, the second fitting groove fitting with the second fitting block, and the top surface of the airtight layer is provided with an exhaust assembly.

[0009] The exhaust assembly is equipped with a check diaphragm.

[0010] The protective layer is composed of a fiberglass reinforced layer and a fine stone concrete surface layer.

[0011] The beneficial effects of this utility model are: (1) In this utility model, the layers of a detachable thermal insulation and waterproof composite layer structure suitable for roof recycling are detachably connected by the mechanical cooperation of interlocking blocks and interlocking grooves, which facilitates single-layer or partial replacement, reduces the amount of work and material waste of overall removal, and significantly improves the recycling rate of the roof system.

[0012] (2) In the present invention, the airtight layer of the removable thermal insulation and waterproof composite layer structure suitable for roof recycling provides a continuous and seamless seal to prevent moisture from penetrating into the building through tiny gaps.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0016] like Figure 1-2 As shown, this utility model discloses a detachable thermal insulation and waterproof composite layer structure suitable for roof recycling, including a roof 1. The roof 1 includes a structural layer 2, which is the load-bearing foundation layer of the roof. It is integrally cast with reinforced concrete and has high load-bearing capacity and impact resistance. A leveling layer 3 is attached to the structural layer 2. The leveling layer 3 is formed by uniformly laying high-strength mortar to correct the unevenness of the surface of the structural layer 2 and ensure the tight bonding of the upper structure. An insulation board 4 is attached to the leveling layer 3. The insulation board 4 has a thermal conductivity of not more than 0.06. Made of high-performance thermal insulation material with a dry density of no more than 250 kg / m³ and a dry density of W / (m·K), it can effectively reduce indoor and outdoor heat exchange and improve the building's energy-saving performance. An airtight layer 5 is attached to the insulation board 4. The airtight layer 5 is an integral and continuous waterproof and airtight membrane that can block water vapor and air infiltration and maintain the airtightness of the roof system. A protective layer 6 is attached to the airtight layer 5, which can prevent ultraviolet aging. A waterproof layer 7 is attached to the protective layer 6. The waterproof layer 7 is formed by flexible waterproof membrane or coating material, which has strong weather resistance, good ductility and durable waterproof performance to ensure that the roof maintains its waterproof and seepage-proof effect for a long time.

[0017] The leveling layer 3 has a first interlocking block 301 at both ends of the top front and back.

[0018] The bottom surface of the insulation board 4 has first fitting grooves 401 at its front and rear ends. The shape and size of the first fitting grooves 401 match the first fitting blocks 301 on the leveling layer 3. During installation, the first fitting grooves 401 and the first fitting blocks 301 are interlocked to achieve precise positioning and stable support of the insulation board 4, thereby preventing displacement or warping of the insulation board 4 due to stress or environmental changes during long-term use. The top surface of the insulation board 4 has second fitting blocks 402 integrally formed at its front and rear ends. The second fitting blocks 402 are used to cooperate with the second fitting grooves 501 on the bottom surface of the adjacent insulation board 4 above, so that a stable vertical positioning connection is formed between the upper and lower insulation boards 4, further improving the assembly accuracy and structural stability of the overall insulation structure, and effectively reducing the thermal bridging effect at the joints.

[0019] The bottom surface of the airtight layer 5 has second interlocking grooves 501 extending laterally at its front and rear ends. The groove size and depth of each second interlocking groove 501 are matched with the outer dimensions of the second interlocking block 402 to achieve stable insertion and fixation during installation and form a continuous sealing interface, thereby effectively preventing displacement or gaps in the airtight layer 5 during use. The top surface of the airtight layer 5 is provided with an exhaust assembly 502, which is used to promptly exhaust water vapor and gas generated inside the roof under conditions of temperature difference changes or humidity accumulation, while blocking external rainwater, dust and impurities from entering, thereby maintaining a dry and stable airtight environment inside the roof and extending the service life of the waterproof layer 7 and the insulation board 4.

[0020] The exhaust assembly 502 is equipped with a check diaphragm to prevent external rainwater, dust and impurities from entering.

[0021] The protective layer 6 is composed of a fiberglass reinforced layer and a fine stone concrete surface layer. The fiberglass reinforced layer is formed by multi-directional laying of high-strength alkali-resistant glass fiber fabric, with the fiber diameter controlled between 9 and 13 μm to improve tensile strength and crack resistance. The fine stone concrete surface layer is made of hard crushed stone with a particle size of no more than 10 mm and high-grade cement, with a water-cement ratio controlled between 0.35 and 0.45. During the mixing process, an appropriate amount of anti-seepage agent and shrinkage compensator are added to enhance the overall density and impermeability of the protective layer 6. The fiberglass reinforced layer and the fine stone concrete surface layer are integrated into a composite structure through a wet-laying process during construction, so that the protective layer 6 has both excellent mechanical load-bearing capacity and can effectively resist external impact, temperature and humidity changes, and fatigue damage under long-term load, thereby extending the overall service life of the roof 1 and improving maintenance convenience.

[0022] Working principle: Through the synergistic effect of multiple layers including structural layer 2, leveling layer 3, insulation board 4, airtight layer 5, protective layer 6, and waterproof layer 7, the roof 1 achieves efficient insulation and long-lasting waterproofing under reusable conditions. During installation, the first interlocking block 301 on the leveling layer 3 precisely interlocks with the first interlocking groove 401 at the bottom of the insulation board 4, achieving stable positioning of the insulation board 4. The insulation boards 4 are mutually locked together by the second interlocking block 402 and the second interlocking groove 501 at the bottom of the airtight layer 5, forming a stable vertical connection and continuous sealing interface, reducing thermal bridging and preventing displacement. The airtight layer 5 uses a check diaphragm and exhaust component 502 to promptly discharge internal moisture and gas, keeping the interior dry and preventing external impurities from intruding. The protective layer 6 utilizes an integrated composite structure of fiberglass reinforcement and fine stone concrete surface layer to improve crack resistance, seepage prevention, and impact resistance. The waterproof layer 7 provides long-term weather resistance and seepage prevention, thus maintaining the insulation, waterproofing, and structural stability of the roof 1 during long-term use and multiple disassembly and reassembly cycles.
