Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to prefabricated insulated roof structures. Background Technology
[0002] Compared to traditional concrete buildings, steel structures use steel plates or sections instead of reinforced concrete, resulting in higher strength and better earthquake resistance. Furthermore, because components can be factory-fabricated and installed on-site, construction time is significantly reduced. The reusability of steel greatly reduces construction waste, making it more environmentally friendly, and thus it is widely adopted worldwide in both industrial and residential buildings. However, most existing steel structures are constructed entirely of welded steel. The high thermal conductivity of steel in pure steel structures easily transfers heat between indoors and outdoors, increasing building energy consumption. In summer, solar heat is transferred through the steel structure walls to the interior, raising room temperature; in winter, heat is transferred to the outside through the walls, lowering room temperature. This makes the building's internal temperature environment highly susceptible to the influence of external temperatures.
[0003] For example, the patent CN213329382U describes a thermally insulated steel structure for buildings. The patent states that "the thermally insulated steel structure for buildings enhances the insulation effect of the main steel plate by using XPS extruded polystyrene insulation boards, thus giving the steel structure excellent insulation capabilities; the use of Dike aluminum foil insulation rolls effectively insulates the main steel plate, giving the steel structure thermal insulation capabilities; and the fixing mechanism, with its fixing plates, through holes, and threaded holes, allows for quick and easy installation of the insulation boards onto the main steel plate. Furthermore, the fixing structure of the insulation boards in this design is stable and reliable, and easy to install and remove." The patent also points out the technical deficiency that "existing steel structures for buildings lack thermal insulation capabilities."
[0004] In summary, the existing technology has the following technical problems: the existing steel structure of buildings does not have the ability to insulate and heat-insulate. Therefore, this application proposes a prefabricated insulated roof structure to provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content

The anti-fog coating can effectively prevent condensation on the supporting and connecting steel plates due to temperature differences. The ceramic fiber blanket has a thermal insulation effect, and the aluminum foil layer can reflect external heat, making the internal temperature more constant. This effectively reduces condensation on the surface of the supporting steel plates caused by indoor and outdoor temperature differences, prevents the leakage of cold or hot air from the room, and increases the building's energy efficiency. Furthermore, both the outdoor and indoor insulation components have thermal insulation effects.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] The prefabricated insulated roof structure specifically includes: a supporting steel plate and a connecting steel plate, the connecting steel plate being fixed at both ends of the supporting steel plate; a ceramic fiber blanket, the surfaces of the supporting steel plate and the connecting steel plate being jointly covered with an anti-fog coating; the ceramic fiber blanket being fixed to the surface of the anti-fog coating; an aluminum foil layer being fixed to the surface of the ceramic fiber blanket; and outdoor insulation components and indoor insulation components being symmetrically arranged on both sides of the supporting steel plate and on the surface of the aluminum foil layer.

The depth of the first snap-fit groove is greater than that of the second snap-fit groove. The top and bottom of the outdoor insulation component and the indoor insulation component are respectively snapped into the interior of the first snap-fit groove and the second snap-fit groove.
[0010] As a preferred embodiment of the prefabricated insulated roof structure provided by this utility model, the outdoor insulation component includes a first ceramic fiber board, and a stainless steel anti-corrosion layer is fixed on the side of the first ceramic fiber board away from the supporting steel plate.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0028] As mentioned in the background section, existing steel structures for buildings do not have the ability to provide thermal insulation.
[0029] To solve this technical problem, this utility model provides a prefabricated insulated roof structure.
[0030] For details, please refer to Figure 1-3 The prefabricated insulated roof structure specifically includes: a supporting steel plate 1 and a connecting steel plate 2, the connecting steel plate 2 being fixed at both ends of the supporting steel plate 1; a ceramic fiber blanket 7, the surfaces of the supporting steel plate 1 and the connecting steel plate 2 being jointly covered with an anti-fog coating 6; the ceramic fiber blanket 7 being fixed on the surface of the anti-fog coating 6; an aluminum foil layer 8 being fixed on the surface of the ceramic fiber blanket 7; and outdoor insulation components and indoor insulation components being symmetrically arranged on both sides of the supporting steel plate 1 and on the surface of the aluminum foil layer 8.
[0031] The prefabricated insulated roof structure provided by this utility model can effectively prevent condensation on the supporting steel plate 1 and connecting steel plate 2 due to temperature difference through the anti-fog coating 6. The ceramic fiber blanket 7 has a heat insulation effect, and the aluminum foil layer 8 can reflect external heat, making the internal temperature more constant. This effectively reduces the phenomenon of condensation on the surface of the supporting steel plate 1 caused by the temperature difference between indoors and outdoors, prevents the leakage of cold or hot air from the room, increases the building's energy-saving effect, and both the outdoor and indoor insulation components have a heat insulation effect.
[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0033] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0034] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example 1
[0036] Please refer to Figure 1-3 ,
[0037] The system includes a supporting steel plate 1, a connecting steel plate 2, and a ceramic fiber blanket 7. The connecting steel plate 2 is fixed to both ends of the supporting steel plate 1. Both the supporting steel plate 1 and the connecting steel plate 2 are covered with an anti-fog coating 6. The ceramic fiber blanket 7 is fixed to the surface of the anti-fog coating 6, and an aluminum foil layer 8 is fixed to the surface of the ceramic fiber blanket 7. Specifically, the anti-fog coating 6, the ceramic fiber blanket 7, and the aluminum foil layer 8 are bonded together with adhesive. The anti-fog coating 6 effectively prevents condensation on the supporting steel plate 1 and the connecting steel plate 2 due to temperature differences, thus preventing fogging on their surfaces. The anti-fog coating 6, which is composed of three parts, namely hydrophilic polymer, crosslinking agent and surfactant, is free from rusting. The main component is hydrophilic polymer, which absorbs moisture. To enhance the water resistance and friction resistance of the resin, a crosslinking agent is introduced. The surfactant is added to improve surface wettability and enhance anti-fog performance. The ceramic fiber blanket 7 has a heat insulation effect, and the aluminum foil layer 8 can reflect external heat, making the internal temperature more constant. This effectively reduces the condensation on the surface of the supporting steel plate 1 caused by the temperature difference between indoors and outdoors, prevents the leakage of cold or hot air from the room, and increases the building's energy-saving effect.
[0038] Outdoor insulation components and indoor insulation components are symmetrically arranged on both sides of the supporting steel plate 1 and on the surface of the aluminum foil layer 8. Specifically, both outdoor and indoor insulation components have thermal insulation effects. By adopting different structures for the outdoor and indoor insulation components, the indoor insulation components make it difficult for indoor hot or cold air to be transferred to the supporting steel plate 1, while the outdoor insulation components, while having a certain thermal insulation effect, can effectively resist the erosion of external rain and sunlight.
[0039] The outdoor insulation component includes a first ceramic fiber board 10, with a stainless steel anti-corrosion layer 9 fixed to the side of the first ceramic fiber board 10 away from the supporting steel plate 1. The indoor insulation component includes a second ceramic fiber board 11, with an insulation extruded polystyrene board 3 fixed to the side of the second ceramic fiber board 11 away from the supporting steel plate 1. The insulation extruded polystyrene board 3 has multiple material-saving holes 17 inside. Specifically, the second ceramic fiber board 11 and the first ceramic fiber board 10 are used for thermal insulation. By bonding the stainless steel anti-corrosion layer 9 to the side of the first ceramic fiber board 10 away from the supporting steel plate 1, not only can the overall structural strength of the outdoor insulation component be improved, but it can also block sunlight and rain from the outside, thus extending the service life of the outdoor insulation component. By opening multiple material-saving holes 17 inside the insulation extruded polystyrene board 3, the thermal insulation effect of the insulation extruded polystyrene board 3 can be increased and the material usage can be reduced. Example 2
[0040] The fixing method for the outdoor and indoor insulation components of the prefabricated insulated roof structure provided in Example 1 is further optimized, specifically, as follows: Figure 1-2 As shown,
[0041] A first L-shaped mounting strip 4 is symmetrically arranged on both sides of the bottom of the supporting steel plate 1, and a second L-shaped mounting strip 5 is symmetrically arranged on both sides of the top of the supporting steel plate 1. The second L-shaped mounting strip 5 and the first L-shaped mounting strip 4 are respectively fixed to the connecting steel plate 2. The outdoor insulation component and the indoor insulation component are respectively located between the first L-shaped mounting strip 4 and the second L-shaped mounting strip 5 and the aluminum foil layer 8. A first snap-fit groove is formed between the second L-shaped mounting strip 5 and the aluminum foil layer 8, and a second snap-fit groove is formed between the first L-shaped mounting strip 4 and the aluminum foil layer 8. The depth of the first snap-fit groove is greater than that of the second snap-fit groove. The top and bottom of the outdoor insulation component and the indoor insulation component are respectively snapped into the first snap-fit groove and the second snap-fit groove. During installation, the second L-shaped mounting strip 5 and the first L-shaped mounting strip 4 are first fixed to the connecting steel plate 2 with self-drilling screws. Then, the tops of the outdoor insulation component and the indoor insulation component are respectively inserted into the first snap-fit groove. Then, the bottoms of the outdoor insulation component and the indoor insulation component are lifted and inserted into the second snap-fit groove, thereby fixing the outdoor insulation component and the indoor insulation component. This can effectively improve the efficiency of disassembly and assembly of the outdoor insulation component and the indoor insulation component. Example 3
[0042] For the prefabricated insulated roof structure provided in Example 1, further optimization is needed when multiple extruded polystyrene insulation boards 3 need to be installed. Specifically, for example... Figure 4-5 As shown,
[0043] The thermal insulation extruded polystyrene board 3 has a fixing groove 12 and a connecting groove 13 at both ends. A connecting block 16 is provided between adjacent thermal insulation extruded polystyrene boards 3. A fixing seat 14 is fixed to one end of the connecting block 16, and an acrylic double-sided adhesive 15 is fixed to the end of the fixing seat 14 away from the connecting block 16. The fixing seat 14 is fixed inside the fixing groove 12 by the acrylic double-sided adhesive 15. The connecting block 16 is used to insert into the connecting groove 13. Specifically, the acrylic double-sided adhesive 15 is provided by the factory. During installation, when multiple thermal insulation extruded polystyrene boards 3 need to be installed, the fixing seat 14 is fixed inside the fixing groove 12 by the acrylic double-sided adhesive 15, and the connecting block 16 is inserted into the connecting groove 13. This can effectively increase the flatness of the joint between the thermal insulation extruded polystyrene boards 3.
[0044] The usage process of the prefabricated insulated roof structure provided by this utility model is as follows:
[0045] Technical principle: The ceramic fiber blanket 7 has a heat insulation effect, and the aluminum foil layer 8 can reflect the heat from the outside, thereby effectively reducing the phenomenon of condensation on the surface of the supporting steel plate 1 caused by the temperature difference between indoors and outdoors, and preventing the cold or hot air from escaping from the room. The second ceramic fiber board 11 and the first ceramic fiber board 10 are used for heat insulation. By bonding the stainless steel anti-corrosion layer 9 to the side of the first ceramic fiber board 10 away from the supporting steel plate 1, not only can the overall structural strength of the outdoor heat insulation component be improved, but it can also block the sunlight and rain from the outside.
[0046] During installation, the second L-shaped mounting strip 5 and the first L-shaped mounting strip 4 are first fixed to the connecting steel plate 2 with self-drilling screws. Then, the tops of the outdoor insulation component and the indoor insulation component are inserted into the first snap-fit groove respectively. Then, the bottoms of the outdoor insulation component and the indoor insulation component are lifted and inserted into the second snap-fit groove, thereby fixing the outdoor insulation component and the indoor insulation component. This can effectively improve the efficiency of disassembly and assembly of the outdoor insulation component and the indoor insulation component.
[0047] Acrylic double-sided tape 15 is included with the product. During installation, when multiple insulation extruded polystyrene boards 3 need to be installed, the fixing base 14 is fixed inside the fixing groove 12 with acrylic double-sided tape 15, and the connecting block 16 is inserted into the connecting groove 13. This can effectively increase the flatness of the joints between insulation extruded polystyrene boards 3.
