Description

Technical Field

[0001] The utility model relates to the field of building waterproofing, in particular to a waterproof and thermal insulation layer structure for a roof of a teaching building. Background Art

[0002] The design of the roof structure layer is a science. With the development of new waterproof materials and thermal insulation materials and the emergence of new structures, the roof structure layer is also constantly changing. In addition, the expansion time of general teaching buildings is concentrated in August and September. This makes the roof of the teaching building prone to cracking due to high temperature exposure when the concrete is just poured. At the same time, the roof's waterproof and thermal insulation layers are also easily affected by high temperatures.

[0003] After searching, the patent application number CN201921480319.3 discloses a building waterproof and heat-insulating layer structure, including a base layer, the upper surface of the base layer is fixedly connected to a lower waterproof board, the upper surface of the lower waterproof board is fixedly connected to a lower insulation board, an upper insulation board with the same structure is arranged above the lower insulation board, a leveling layer is arranged between the upper insulation board and the lower insulation board, the upper and lower surfaces of the leveling layer are symmetrically connected to a plurality of uniformly staggered reinforcing rods, and the reinforcing rods are arranged obliquely, and the upper insulation board and the lower insulation board are connected to the leveling layer. The spaces between the teaching buildings are filled with a waterproof layer, the upper surface of the upper insulation board is fixedly connected to the upper waterproof board, and the upper surface of the upper waterproof board is connected to a reflective thermal insulation coating layer. This patented outer reflective thermal insulation coating layer can play a good heat-insulating role and avoid being affected by the external high-temperature environment. However, since the expansion of teaching buildings is mostly carried out in high-temperature weather, it will cause problems such as blistering and shrinkage cracks in the waterproof layer. At the same time, high temperature weather will also cause the moisture in the newly poured concrete on the roof to evaporate quickly, resulting in cracks, and causing the waterproof layer and insulation layer to dry and crack.

[0004] Therefore, a teaching building roof waterproof insulation layer structure is proposed to avoid cracking of poured concrete in hot weather during a short construction period, and to avoid blistering and shrinkage cracks in the waterproof layer in hot weather. Utility Model Content

[0005] In order to solve the above problems existing in the prior art, the utility model provides a teaching building roof waterproof insulation layer structure.

[0006] The technical solution of the utility model is as follows:

[0007] A teaching building roof waterproof and thermal insulation layer structure comprises a concrete layer, a thermal insulation layer and a waterproof layer, wherein the thermal insulation layer is laid on the top of the concrete layer, the waterproof layer is arranged on the top of the thermal insulation layer, and the top of the waterproof layer is provided with a protective layer; the protective layer comprises an isolation layer and a covering cloth layer, wherein the covering cloth layer is laid flat on the waterproof layer, the isolation layer is arranged on the top of the covering cloth layer, and a plurality of notches are evenly provided on the surface of the isolation layer; a vapor barrier layer and a filling layer are laid from top to bottom between the concrete layer and the thermal insulation layer.

[0008] Preferably, the insulation layer is made of rock wool board, foam cement board or glass wool board.

[0009] Preferably, the waterproof layer includes a waterproof coating layer and a waterproof roll material layer. The waterproof coating layer is made of a polymer synthetic material and is reciprocatingly rolled on the top surface of the insulation layer. The waterproof roll material layer is laid above the waterproof coating layer; the waterproof roll material layer is made of asphalt waterproof roll material, polymer modified asphalt waterproof roll material or synthetic polymer waterproof roll material.

[0010] Preferably, the isolation layer is made of polyethylene, polypropylene or polyvinyl chloride.

[0011] Preferably, the cover cloth layer is made of water-absorbent felt.

[0012] Preferably, the concrete layer includes a hanging mesh and a pouring layer, the hanging mesh is arranged in a grid shape and laid on the roof, and the outer wall of the hanging mesh is formed by pouring concrete to form the pouring layer.

[0013] Preferably, the vapor barrier layer includes a felt layer and an oil layer, the outer wall of the filling layer is paved with the felt layer, and the surface of the felt layer is coated with the oil layer; the filling layer is laid on the surface of the concrete and the surface of the filling layer is an inclined slope.

[0014] Preferably, the filling layer is made of slag or expanded perlite.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model arranges an isolation layer, a cover cloth layer and a gap. The cover cloth layer is laid flat on the waterproof layer, and then the isolation layer is laid flat on the cover cloth layer. Water is then sprinkled on the isolation layer. The water flows through the gap in the isolation layer and is absorbed by the cover cloth layer. This ensures that in hot weather, the airtight isolation layer can reduce the volatilization of water absorbed by the cover cloth layer. The water absorbed by the cover cloth layer can slowly volatilize through the gap in the isolation layer, thereby protecting the waterproof layer and the thermal insulation layer and preventing blistering and shrinkage cracks in the waterproof layer in hot weather.

[0017] 2. The utility model lays the hanging mesh on the roof through the provision of a protective layer, a hanging mesh and a pouring layer, and then pours concrete on the hanging mesh to form a pouring layer. The protective layer reduces moisture loss, so that in hot weather, the roof temperature will not always be high due to the influence of moisture. The combination of the hanging mesh and the pouring layer reduces the probability of the roof drying out and cracking, thus avoiding cracking of concrete poured in a short construction period in hot weather.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 3 A teaching building roof waterproof insulation layer structure includes a concrete layer 6, an insulation layer 3 and a waterproof layer 2. The insulation layer 3 is laid on the top of the concrete layer 6, the waterproof layer 2 is arranged on the top of the insulation layer 3, and the top surface of the waterproof layer 2 is provided with a protective layer 1; the protective layer 1 includes an isolation layer 12 and a covering cloth layer 13, the covering cloth layer 13 is laid flat on the waterproof layer 2, and the isolation layer 12 is arranged on the top surface of the covering cloth layer 13, and a plurality of notches 11 are evenly opened on the surface of the isolation layer 12; a vapor barrier layer 4 and a filling layer 5 are laid from top to bottom between the concrete layer 6 and the insulation layer 3.

[0025] In hot weather, the airtight isolation layer 12 can reduce the volatilization of moisture absorbed by the cover cloth layer 13. The moisture absorbed by the cover cloth layer 13 can slowly volatilize through the gap 11 of the isolation layer 12, thereby protecting the waterproof layer 2 and the thermal insulation layer 3 and preventing the waterproof layer 2 from bubbling and shrinkage cracks in hot weather.

[0026] Furthermore, the thermal insulation layer 3 is made of rock wool board, foam cement board or glass wool board.

[0027] Furthermore, the waterproof layer 2 includes a waterproof coating layer and a waterproof roll material layer. The waterproof coating layer is made of a polymer synthetic material and is reciprocatingly rolled on the top surface of the insulation layer 3. The waterproof roll material layer is laid above the waterproof coating layer; the waterproof roll material layer is made of asphalt waterproof roll material, polymer modified asphalt waterproof roll material or synthetic polymer waterproof roll material.

[0028] After the waterproof coating is repeatedly applied and solidified, a waterproof film, namely the waterproof coating layer, can be formed on the top surface of the insulation layer 3. The waterproof roll material layer is then laid on top of the waterproof coating layer, mainly used to prevent leakage of external rainwater or groundwater.

[0029] Furthermore, the isolation layer 12 is made of polyethylene, polypropylene or polyvinyl chloride, and thus the isolation layer 12 makes the surface impermeable to gas and water molecules.

[0030] Furthermore, the covering cloth layer 13 is made of water-absorbent felt; the felt is made of natural water-absorbent fiber material, which is used to absorb and retain moisture to prevent excessive volatilization and cracking of the concrete surface. It has good air permeability and filtering properties, will not cause pollution to the concrete surface, and has moisture-proof and anti-corrosion properties.

[0031] Furthermore, the concrete layer 6 includes a hanging mesh 61 and a pouring layer 62. The hanging mesh 61 is arranged in a grid shape and laid on the roof. The outer wall of the hanging mesh 61 is poured with concrete to form a pouring layer 62. After the hanging mesh 61 is completed, the concrete is used for plastering to evenly distribute the dots on the wall, ensuring that the hanging mesh 61 is tightly combined with the wall to form a pouring layer 62.

[0032] The hanging mesh 61 can be made of metal material and then staggered horizontally and vertically. The main purpose is to enhance the structural strength of the wall, prevent cracks, and improve the durability and safety of the building; the protective layer 1 reduces moisture loss, so that in hot weather, the roof temperature will not always be high due to the influence of moisture. The combination of the hanging mesh 61 and the pouring layer 62 reduces the probability of roof cracking, avoiding cracking of concrete poured in a short construction period in hot weather.

[0033] Furthermore, the vapor barrier 4 includes a felt layer 41 and an oil layer 42 . The outer wall of the filling layer 5 is paved with the felt layer 41 , and the surface of the felt layer 41 is coated with the oil layer 42 . The filling layer 5 is laid on the surface of the concrete 6 and the surface of the filling layer 5 is an inclined slope.

[0034] It is necessary to keep the felt layer 41 flat and tight. Special glue or adhesive can be used to stick the felt layer 41 on the base layer, and the joints between the felt layers 41 should be ensured to fit tightly to avoid gaps. When applying the oil layer 42, attention should be paid to the uniformity and thickness of the paint to avoid missing paint or applying too thickly. At the same time, making the surface of the filling layer 5 inclined can allow rainwater to drain quickly.

[0035] Furthermore, the filling layer 5 is made of slag or expanded perlite.

[0036] The working principle of this utility model:

[0037] In the present invention, a hanging mesh 61 is laid flat on the roof, and then concrete is poured on the hanging mesh 61 to form a pouring layer 62. Then, slag or expanded perlite is laid flat on the concrete layer 6 to form a filling layer 5, and the filling layer 5 is made to have a certain slope so that rainwater can be quickly drained. A felt layer 41 is laid flat on the filling layer 5, and then a waterproof coating is evenly applied on the felt layer 41 to form an oil layer 42. The felt layer 41 and the oil layer 42 form a vapor barrier 4. A thermal insulation layer 3 is laid on the vapor barrier 4, and a waterproof layer 2 is added on the thermal insulation layer 3. The waterproof layer 2 includes a waterproof coating layer and a waterproof coiled material layer. The waterproof coating is made of polymer synthetic materials. After the waterproof coating is applied and cured, a waterproof film can be formed on the surface of the base layer. By spreading the cover cloth layer 13 flatly on the waterproof layer 2, and then spreading the isolation layer 12 flatly on the cover cloth layer 13, and then sprinkling water on the isolation layer 12, the water flows through the gap 11 of the isolation layer 12 and is absorbed by the cover cloth layer 13. In hot weather, the airtight isolation layer 12 can reduce the volatilization of moisture absorbed by the cover cloth layer 13. The moisture absorbed by the cover cloth layer 13 can slowly volatilize through the gap 11 of the isolation layer 12, thereby protecting the waterproof layer 2 and the thermal insulation layer 3.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
