Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a roof insulation structure. Background Art

[0002] In modern architecture, thermal insulation plays a crucial role in a building's energy efficiency and comfort. With increasing demand for energy conservation and environmental protection, building insulation technology has gained widespread application. The primary purpose of building insulation is to reduce heat transfer between the building's exterior and interior, thereby lowering energy consumption. Installing insulation materials on a building's exterior walls, roofs, and other areas to form a thermal insulation layer effectively blocks heat loss, keeping the interior warm in winter and cool in summer. Common insulation materials include polystyrene boards, rock wool, and glass wool, all of which offer excellent thermal insulation and low thermal conductivity.

[0003] However, in practice, building insulation layers are prone to shedding. This problem poses a serious threat to the safety and service life of buildings. There are many reasons for insulation shedding. Firstly, the quality of insulation materials varies greatly. Some inferior materials are prone to aging and deformation during use, which can weaken their bond with the base wall and eventually cause them to fall off. Secondly, improper construction procedures are also a major cause of insulation shedding. For example, improper base wall preparation, insufficient adhesive, and inadequately secured insulation panels can all lead to insulation shedding in the future. Furthermore, the impact of the natural environment cannot be ignored. Long-term exposure to wind, sun, rain, snow, and frost can gradually age and damage insulation materials, reducing their bond with the wall and increasing the risk of shedding.

[0004] The shedding of thermal insulation not only affects the appearance and thermal insulation performance of the building, but also poses a threat to the safety of pedestrians. Therefore, how to solve the problem of easy shedding of thermal insulation layers in buildings has become an important issue facing the current construction industry. Utility Model Content

[0029] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," and the like, indicating positions or location relationships, are based on the positions or location relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model depending on the specific circumstances.

[0032] The utility model provides a roof insulation structure, comprising a base layer 1, a reinforced concrete layer 2 and a thermal insulation layer 3, wherein the reinforced concrete layer 2 is located above the base layer 1, and the thermal insulation layer 3 is stacked between the base layer 1 and the reinforced concrete layer 2 and connected to the base layer 1 and the reinforced concrete layer 2 respectively.

[0033] The roof may be a flat roof or a sloping roof.

[0034] Specifically, in some embodiments, the above-mentioned reinforced concrete layer 2 includes an inclined top wall 21 that is at least partially inclined. At this time, the thickness of the above-mentioned reinforced concrete layer 2 at different positions can remain consistent or different; accordingly, the surface of the side of the base layer 1 of the roof with the above-mentioned inclined top wall 21 close to the reinforced concrete layer 2 can be a plane or an inclined surface, and this embodiment does not limit it.

[0035] See also Figure 1 , Figure 1 It is a structural schematic diagram of a certain embodiment of the roof insulation structure provided by the utility model.

[0036] In this embodiment, by adjusting the position of the thermal insulation layer 3 so that it is located between the base layer 1 and the reinforced concrete layer 2, the possibility of the thermal insulation layer 3 being damaged or falling off due to temperature differences, corrosion, etc. during the use of the building is effectively reduced, thereby avoiding property losses and personal injuries caused by the falling off of the thermal insulation layer 3.

[0037] The above-mentioned reinforced concrete layer 2 can provide effective physical protection for the thermal insulation layer 3, preventing the thermal insulation layer 3 from being damaged by natural factors such as external force impact, wind and rain, ultraviolet radiation, etc., which helps to extend the service life of the thermal insulation layer 3; it can also prevent the thermal insulation layer 3 from being damaged by accidents such as animal destruction and human trampling.

[0038] In addition to the aforementioned effects, the reinforced concrete layer 2 located outside the thermal insulation layer 3 can also increase the overall strength and rigidity of the roof to a certain extent, improving the roof's load-bearing capacity. This is particularly true for roofs with a certain slope, as it can better resist the gravity component and other external forces acting on the slope, reducing the risk of roof deformation and cracking. The reinforced concrete layer 2 can then provide a relatively stable working platform for roof maintenance and renovation. When the roof needs to be repaired, equipment replaced, or other renovations are required, the reinforced concrete layer 2 can withstand the weight of construction personnel and equipment, facilitating construction operations.

[0039] Furthermore, the reinforced concrete layer 2 also serves as an auxiliary waterproof layer 12, working together with other roof waterproof structures (e.g., waterproof layer 12) to enhance the roof's waterproofing. Even if the primary waterproof layer 12 is partially damaged, the reinforced concrete layer 2 can still prevent moisture from penetrating the thermal insulation layer 3 and the interior of the house to a certain extent, reducing the possibility of leakage.

[0040] As a further improvement of the present invention, it further includes tiles 6 located on the side of the reinforced concrete layer 2 facing away from the thermal insulation layer 3 .

[0041] A plurality of tiles 6 can be laid on the roof in an overlapping manner, that is, on the side of the reinforced concrete layer 2 facing away from the thermal insulation layer 3 , including the inclined top wall 21 .

[0042] Tiles 6 have a certain waterproof effect, effectively blocking rainwater, snowwater, and other water from entering the roof, protecting the interior structure from water erosion, and helping to guide rainwater and other water to drain smoothly off the roof. Furthermore, tiles 6 have certain thermal insulation properties, reducing the amount of solar radiation entering the room during the summer and lowering the indoor temperature. They also provide a certain degree of insulation in the winter, reducing indoor heat loss. In addition to the aforementioned effects, tiles 6 also have a certain decorative effect, enhancing the overall appearance of the building and making the house more distinctive and personalized. Tiles 6 can also withstand certain external impacts, helping to protect the roof structure, such as fallen branches and hail, and protecting the roof's base layer 1, thermal insulation layer 3, and reinforced concrete layer 2 from damage.

[0043] In some embodiments, the thickness of the reinforced concrete layer 2 is about 80 mm.

[0044] The reinforced concrete layer 2 is made of a mixture of steel bars and concrete. During preparation, a steel mesh can be bundled at a corresponding position as needed, and then concrete is poured to form the reinforced concrete layer 2.

[0045] The prepared reinforced concrete layer 2 can cooperate with the base layer 1 to form an upper and lower concrete structure layer 11 whose airtightness meets the requirements of building construction, and the thermal insulation layer 3 is located between the two.

[0046] In some embodiments, at least a portion of the side of the reinforced concrete layer 2 facing away from the base layer 1 forms the inclined top wall 21. Depending on the roof shape, if the roof is entirely sloped, the side of the reinforced concrete layer 2 facing away from the base layer 1 will be entirely sloped top wall 21. If the roof is only partially sloped, the side of the reinforced concrete layer 2 facing away from the base layer 1 will be partially sloped top wall 21 and partially horizontal top wall. This embodiment does not limit the distribution region or area of the inclined top wall.

[0047] In order to facilitate the pouring preparation of the above-mentioned reinforced concrete layer 2, in some embodiments, a baffle 5 is laid between the above-mentioned reinforced concrete layer 2 and the thermal insulation layer 3. Figure 1 .

[0048] In addition, in this embodiment or other similar embodiments, the roof insulation structure also includes a limiting anti-step 4 located on the base layer 1, which is connected to the thermal insulation layer 3 and the reinforced concrete layer 2, and is used to limit the reinforced concrete layer 2 and the thermal insulation layer 3 in the circumferential direction.

[0049] The above-mentioned limiting anti-ridge 4 can be used as a slurry retaining plate, which can not only help to withstand the lateral pressure of concrete poured on the roof slope, but also provide a certain stopping effect on the concrete, help block the concrete, and prevent the concrete from overflowing from the area to be poured during the pouring process.

[0050] As a further improvement of the present invention, the limiting anti-step 4 is located on one side of the reinforced concrete layer 2 in the circumferential direction, and the limiting anti-step 4 is arranged close to the end of the inclined top wall 21 that is inclined downward.

[0051] In some embodiments, an airtightness detection hole 22 is provided in the reinforced concrete layer 2 obtained by the pouring. The structure of the airtightness detection hole 22 can be found in FIG. Figure 2 The airtightness detection hole 22 is used to cooperate with the waterproof monitoring system disclosed in the relevant technology.

[0052] Specifically, a vacuum detection sensor can be installed outside the airtight detection hole 22. When in use, in addition to achieving sealing and waterproofing of the reinforced concrete layer 2 during construction, it can also cooperate with corresponding detection equipment to achieve long-term monitoring and detection of the waterproof effect of the construction joints formed in the reinforced concrete layer 2.

[0053] The processing technology of construction joints is existing technology and will not be described in detail here.

[0054] In some embodiments, the reinforced concrete layer 2 includes a steel mesh and a degradable tube, and the degradable tube is arranged on the steel mesh to form an airtight detection hole 22.

[0055] The degradable tube degrades naturally after the concrete poured outside the steel mesh solidifies for a certain period of time, thereby forming the airtightness detection hole 22 for detecting the airtightness of the reinforced concrete layer 2. The airtightness detection hole 22 is a hollow tubular structure extending into the reinforced concrete layer 2. The end of the hole extending to the surface of the reinforced concrete layer 2 is a hole-like structure for installing airtightness detection equipment, such as a vacuum detection sensor.

[0056] In some embodiments, in order to improve the bonding strength between the thermal insulation layer 3 and the base layer 1 and the reinforced concrete layer 2 , the thermal insulation layer 3 is prepared after the reinforced concrete layer 2 .

[0057] Specifically, at least two guide holes 41 are provided on the limiting anti-step 4, and the guide holes 41 are used to connect the thermal insulation layer 3 with the external environment.

[0058] During actual construction, the above-mentioned limiting anti-step 4 with the guide hole 41 can be first set at the corresponding position of the base layer 1, and the limiting anti-step 4 is fixedly set on the base layer 1. Subsequently, the corresponding surface of the roof for setting the thermal insulation layer 3 is evenly laid with a placeholder material 7 (the placeholder material 7 can be sand beads, river sand, etc.), and the laying thickness of the placeholder material 7 is the thickness of the thermal insulation layer 3. A baffle 5 is laid on the surface of the placeholder material 7, and then a steel mesh is tied on the baffle 5, and a degradable pipe is laid on the steel mesh, and then concrete is poured. After the reinforced concrete layer 2 is prepared, the above-mentioned roof structure is as follows Figure 3AAs shown, the air tightness of the base layer 1 and the reinforced concrete layer 2 on both sides of the thickness direction of the placeholder material 7 meet the design requirements. Subsequently, the diversion hole 41 provided on the limit anti-ridge 4 can be opened to allow the placeholder material 7 laid in the previous construction to be discharged. Figure 3B .

[0059] It should be noted that the guide holes 41 are arranged opposite to the place-occupying material 7 , and the guide holes 41 are always in a closed state before the place-occupying material 7 needs to be discharged.

[0060] In actual use, the diversion hole 41 can be used to discharge the placeholder material 7. After the placeholder material 7 is discharged, a cavity structure is formed between the base layer 1 and the reinforced concrete layer 2. Figure 3B At this time, the guide hole 41 can be used for operators to inject foaming material into the cavity structure to form the thermal insulation layer 3.

[0061] Specifically, the structure of the above-mentioned limit anti-ridge 4 is as follows Figure 4 As shown, the number of the guide holes 41 on any one limiting anti-step 4 is 2-3. The number of the guide holes 41 and the distance between two adjacent guide holes 41 can be adjusted according to actual needs.

[0062] In some embodiments, the foaming material used to form the thermal insulation layer 3 can be rigid polyurethane foam, or other similar materials disclosed in related technologies. After the foaming material is injected into the cavity structure, it will form light foam concrete, which will eventually solidify to form the thermal insulation layer 3.

[0063] Rigid polyurethane foam has an extremely low thermal conductivity, typically between 0.020 and 0.024 W / (m·K), effectively preventing heat transfer and significantly reducing a building's energy consumption. Rigid polyurethane foam also offers excellent waterproofing properties. While inherently waterproof, its closed-cell structure prevents water penetration, preventing the degradation of thermal insulation performance. When combined with roofing membranes, it forms an integrated waterproofing and thermal insulation system, enhancing the roof's waterproofing effectiveness.

[0064] In some embodiments, the base layer 1 includes a structural layer 11 and a waterproof layer 12. The waterproof layer 12 is located between the structural layer 11 and the thermal insulation layer 3. Figure 5 .

[0065] At this time, the thermal insulation layer 3 composed of rigid polyurethane foam can better cooperate with the waterproof layer 12, further improving the waterproof effect of the roof slope.

[0066] As a further improvement of the present invention, the waterproof layer 12 includes a vacuum detection pipeline. The vacuum detection pipeline can be combined with the vacuum detection technology disclosed in the relevant art to detect and monitor the waterproof effect of the waterproof layer 12 in real time, providing data support for the detection and repair of the waterproof layer 12.

[0067] It can be understood that the roof insulation structure provided by the embodiment of the present invention can effectively improve the structural strength of the thermal insulation layer 3 by adjusting the thermal insulation layer 3 to be located between the base layer 1 and the reinforced concrete layer 2, realize the built-in thermal insulation layer 3, and reduce the possibility of damage or falling off of the thermal insulation layer 3 due to temperature difference, corrosion and other reasons during the use of the building, thereby avoiding property loss and personal injury caused by the falling off of the thermal insulation layer 3. In order to further improve the bonding strength between the thermal insulation layer 3 and the base layer 1, a guide hole 41 can be provided on the above-mentioned limiting anti-step 4. During construction, the space for arranging the thermal insulation layer 3 is pre-occupied by sand beads or the like, and a limiting anti-step 4 and a baffle 5 are provided outside the space to facilitate the preparation of the reinforced concrete layer 2. After the reinforced concrete layer 2 is prepared, the placeholder material 7 is discharged through the guide hole 41, and after the placeholder material 7 is discharged, light foam concrete is injected into the corresponding space through the guide hole 41 to form the above-mentioned thermal insulation layer 3. At this time, the thermal insulation layer 3 can be more firmly bonded to the base layer 1. The above-mentioned reinforced concrete layer 2 can be formed with an airtightness detection hole 22 for detecting airtightness by providing a degradable tube during processing in the prepared reinforced concrete layer 2, so as to further improve the waterproof sealing effect of the roof.

[0068] The present invention also provides a method for preparing a roof insulation structure, which is used to prepare any of the above-mentioned roof insulation structures, comprising: preparing a reinforced concrete layer 2 outside the base layer 1 of the roof, and forming a thermal insulation layer 3 between the reinforced concrete layer 2 and the base layer 1.

[0069] Specifically, the thermal insulation layer 3 can be a chamber structure filled with an appropriate amount of placeholder material 7, or it can be a vacuum-sealed cavity. This vacuum-sealed cavity can be formed by evacuating the placeholder material 7 using negative pressure. After the vacuum cavity has been used for a certain period of time and has become ineffective due to air leakage, a foaming material or the like can be injected into it to fill the cavity formed by the vacuum-sealed cavity, thereby forming a solid thermal insulation layer 3, thereby achieving secondary repair of the thermal insulation layer 3.

[0070] In other embodiments, the thermal insulation layer 3 may be formed of prefabricated insulation boards filled in the corresponding spaces. Compared with other processing methods, this method can eliminate the use of placeholder materials 7 and the discharge operation, which can greatly improve the production efficiency.

[0071] Furthermore, insulation material can be injected into the above-mentioned cavity with the prefabricated insulation board to fill the gaps formed between the prefabricated insulation board, the base layer 1 and the reinforced concrete layer 2, so as to further improve the bonding strength between the thermal insulation layer 3 and the base layer 1 and the reinforced concrete layer 2, and improve the sealing and sealing effect of the thermal insulation layer 3.

[0072] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
