Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a high-strength, high-wave plastic steel tile. Background Technology

[0002] As is well known, PVC roofing sheets are widely used in various types of buildings, such as portal steel structure factories, chemical plants, warehouses, and coastal buildings, due to their corrosion resistance, lightning protection, noise reduction, high strength, and pollution-free properties. They cover many industrial, aquaculture, and decoration industries.

[0003] Existing one-piece molded PVC roofing sheets have a simple structure and lack an effective internal heat and sound insulation structure. When faced with external temperature changes and noise interference, they cannot provide good heat and sound insulation effects. This is because their overall structure is solid or simple undulating, lacking a proper combination of air layers or other heat and sound insulation materials. Heat and sound can easily penetrate the sheets and be transmitted. Utility Model Content

[0004] Technical problems to be solved

[0005] In order to overcome the problem of poor heat insulation and sound insulation effect of existing high-strength high-wave plastic steel roofing sheets, this utility model provides a high-strength high-wave plastic steel roofing sheet with significant heat insulation and sound insulation performance.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-strength, high-wave PVC roofing sheet, comprising an upper sheet and a lower sheet, both the upper and lower sheets having alternately distributed flat sections and upwardly protruding high-wave sections. The bottom surface of the flat section of the upper sheet is provided with a lower groove, and the top surface of the flat section of the lower sheet is provided with an upper groove. The upper and lower grooves are connected by a thermal break bridge. The upper and lower sheets are spatially corresponding, the high-wave sections of the upper and lower sheets are vertically aligned, and the flat sections of the upper and lower sheets are arranged parallel to each other. The two ends of the thermal break bridge are located within the upper and lower grooves, respectively.

[0008] Preferably, the high-band is an arched protrusion with a flat top. The bottom surface of the flat portion of the high-band of the upper tile is provided with reinforcing ribs distributed along its length. The reinforcing ribs are perpendicular to the sidewalls of the high-band, and both ends of the reinforcing ribs are connected to the sidewalls of the high-band. The bottom surface of the flat portion of the high-band of the lower tile is provided with a limiting groove extending along its length. The limiting groove is located at the center of the bottom surface of the flat portion of the high-band, and both sides of the limiting groove are equidistant from the sidewalls of the high-band. The arched central axes of the high-band of the upper tile and the high-band of the lower tile coincide.

[0009] Furthermore, each flat segment of the upper tile is provided with a lower slot evenly distributed along its length direction, and the number of lower slots is not less than one. The number of upper slots on the top surface of the flat segment of the lower tile is the same as the number of lower slots on the flat segment of the upper tile, and their positions correspond one-to-one.

[0010] Furthermore, both the upper and lower tiles adopt a multi-layer structure design, consisting of an upper base layer, a foam layer, and a lower base layer from top to bottom. The upper and lower base layers are both made of UPVC material, and the foam layer is made of PVC material. The upper base layer, the foam layer, and the lower base layer are bonded together by a hot-pressing process.

[0011] In a further embodiment, the upper surface of the upper tile is covered with an ASA layer, which is completely adhered to the upper surface of the upper tile, with its edges aligned with the edges of the upper tile, and is bonded to the upper tile by an adhesive.

[0012] Based on the aforementioned scheme, the horizontal width of the flat plate segment is greater than the horizontal width of the high-band segment, and the flat plate segment of the upper tile and the flat plate segment of the lower tile are parallel to each other in the horizontal direction.

[0013] Furthermore, when multiple plastic steel tiles are spliced ​​and installed, the high-band sides of adjacent upper tiles are in contact with each other, and the high-band sides of adjacent lower tiles are also in contact with each other.

[0014] Beneficial effects

[0015] This high-strength, high-wave PVC roofing tile adopts a separate combination structure of upper and lower tiles, which are connected by thermal break bridges to form an air layer between the upper and lower tiles. The air layer can effectively block heat transfer, reduce the impact of external sunlight on indoor temperature, and at the same time block sound transmission, significantly improving the product's thermal insulation and sound insulation performance.

[0022] 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.

[0023] See Figures 1-5A high-strength, high-wave PVC roofing sheet includes an upper tile 1 and a lower tile 2. The upper tile 1 has alternating flat sections 3 and upward-protruding high-wave sections 4. The flat sections 3 are relatively flat, and their bottom surfaces are provided with lower grooves 5, which are distributed along the bottom surface of the flat sections 3 for connection with thermal break bridges 7. The high-wave sections 4 protrude upwards, providing longitudinal support for the tile in the entire PVC roofing structure, enhancing the tile's longitudinal compressive strength, and also aiding in drainage. The lower tile 2 also has alternating flat sections 3 and upward-protruding high-wave sections 4. The top surface of the flat sections 3 is provided with upper grooves 6, which correspond to the lower grooves 5 on the bottom surface of the flat sections 3 of the upper tile 1, and are also used to connect with thermal break bridges 7. The high-wave sections 4 of the lower tile 2 and the upper tile 1 are aligned vertically, working together to enhance the vertical strength and stability of the entire PVC roofing sheet, and also playing an auxiliary role in drainage. The flat section 3 and the upper tile 1 are set parallel to each other, forming a relatively stable and flat spatial structure. The two ends of the thermal break bridge 7 are located in the upper slot 6 and the lower slot 5 respectively, thus connecting the upper tile 1 and the lower tile 2. The thermal break bridge 7 plays a key role in the entire plastic steel tile structure. It not only connects the upper and lower tiles 2, making them a whole, but also effectively blocks heat conduction through the tiles, thereby improving the thermal insulation performance of the building. At the same time, due to its connection with the upper and lower slots 5, it enhances the connection stability between the upper and lower tiles 2 to a certain extent, making the entire plastic steel tile structure more reliable. The upper tile 1 and the lower tile 2 are connected by the thermal break bridge 7. The alternating distribution of the flat section 3 and the high-wave section 4, as well as the positional relationship and connection method between the parts, together create the good mechanical and thermal insulation performance of this high-strength high-wave plastic steel tile, meeting the needs of building use.

[0024] First, refer to Figure 1In this embodiment, the high-wave band 4 of the upper tile 1 has an arched protrusion with a flat top. This arched structure gives the tile good mechanical properties, effectively dispersing external pressure and enhancing the tile's load-bearing capacity. On the bottom surface of the flat portion of the high-wave band 4, reinforcing ribs 8 are provided along its length. The reinforcing ribs 8 are perpendicular to the sidewalls of the high-wave band 4, and their ends are connected to the two sidewalls of the high-wave band 4 respectively. The reinforcing ribs 8 further strengthen the structural strength of the high-wave band 4. Like a skeleton, they provide additional support for the high-wave band 4, making it less prone to deformation under pressure, thereby improving the overall compressive strength of the upper tile 1. The high-wave band 4 of the lower tile 2 also has an arched protrusion with a flat top. A limiting groove 9 extending along the length is provided on the bottom surface of its flat portion. The limiting groove 9 is located on the flat portion of the high-wave band 4. The center position of the bottom surface is such that the two sides of the limiting groove 9 are equidistant from the side wall of the high wave section 4. The existence of the limiting groove 9 plays an important role in the assembly and use of the entire plastic steel tile. It can cooperate with other components to achieve the effect of positioning and limiting, ensuring the accurate installation and relative position fixation of each component. The arched center axis of the high wave section 4 of the upper tile 1 and the high wave section 4 of the lower tile 2 coincides. This precise positional correspondence not only ensures the neatness and beauty of the entire plastic steel tile, but more importantly, from a mechanical point of view, it allows the upper and lower tiles 2 to evenly distribute the load when bearing pressure, further enhancing the structural stability and strength of the entire plastic steel tile. At the same time, this coincidence also helps to realize functions such as drainage, ensuring that the water can flow smoothly along the designed path.

[0025] Then, refer to Figure 2 In this embodiment, each flat segment 3 of the upper tile 1 is provided with a lower slot 5. These lower slots 5 are evenly distributed along the length of the flat segment 3, with at least one lower slot 5 in each flat segment 3. The specific number is determined according to actual design requirements. This even distribution allows for a more balanced distribution of force on the flat segment 3 when connecting the thermal break bridge 7, ensuring a stable connection between the upper tile 1 and the thermal break bridge 7. Furthermore, when subjected to external forces, the force can be evenly transmitted to the thermal break bridge 7 and the lower tile 2 through the lower slots 5, avoiding excessive local stress that could lead to structural damage. The upper slot 6 on the top surface of the flat segment 3 of the lower tile 2... The number of slots is exactly the same as the lower slots 5 of the upper tile 1 flat section 3, and their positions correspond one-to-one. This precise correspondence ensures that the thermal break bridge 7 can be accurately embedded between the upper and lower slots 5, achieving a tight connection between the upper and lower tiles 2. When the upper and lower tiles 2 are connected by the thermal break bridge 7, due to the matching of the number and position of the slots, the entire connection structure is subjected to uniform force in the horizontal direction. There will be no stress concentration due to the deviation of the slot position or the inconsistency of the number, thereby improving the stability and reliability of the overall structure of the plastic steel tile and ensuring that it can better withstand various external forces in actual use.

[0026] Secondly, see Figure 3 In this embodiment, the upper base layer 10 is made of UPVC material, which has good weather resistance, corrosion resistance, and high strength, and can directly resist the erosion of the external environment, such as ultraviolet radiation and rain erosion, providing surface protection for the tiles and extending their service life. The foam layer 11 is made of PVC material, and its unique structure gives the tiles excellent heat insulation and sound insulation performance. The tiny pores in the foam layer 11 can effectively block heat transfer, reduce indoor and outdoor heat exchange, and play a role in heat insulation. At the same time, these pores can also absorb and buffer sound, reduce the entry of external noise into the room, and improve the comfort of the living environment. The lower base layer 12 is also made of UPVC material, and it is connected to the upper base layer. The upper layer 10, foam layer 11, and lower layer 12 work together to further enhance the overall strength and stability of the tile. The lower layer 12 bears various pressures from above and distributes them evenly, ensuring that the tile will not easily deform or be damaged during use. The upper layer 10, foam layer 11, and lower layer 12 are combined together through a hot-pressing process. During the hot-pressing process, the high temperature softens the surface of each layer of material, while the pressure is applied to promote their tight fusion and form a solid whole. This combination method not only ensures the connection strength between each layer, but also enables the entire multi-layer structure to work together and give full play to the performance advantages of each layer of material, thereby improving the comprehensive performance of the plastic steel tile and meeting the needs of the construction industry for high strength, heat insulation, sound insulation, and other aspects.

[0027] Again, see Figure 5 In this embodiment, the upper surface of the upper tile 1 is covered with an ASA layer 13. The ASA layer 13 is closely attached to the upper surface of the upper tile 1, and its edges are precisely aligned with the edges of the upper tile 1. The ASA layer 13 is firmly bonded to the upper tile 1 by an adhesive. The ASA layer 13 has good weather resistance, UV resistance and excellent color stability. It can effectively protect the upper tile 1 from the erosion of natural factors such as sunlight and wind and rain, prevent the upper tile 1 from aging and fading, extend its service life and maintain its beautiful appearance.

[0028] In addition, see Figure 2 In this embodiment, the horizontal width of the flat plate segment 3 is greater than the horizontal width of the high-wave segment 4. This width design helps to enhance the overall stability of the PVC roofing sheet. The larger flat plate segment 3 provides a wider support area, allowing the PVC roofing sheet to better withstand pressure after installation. The flat plate segment 3 of the upper tile 1 and the flat plate segment 3 of the lower tile 2 are strictly parallel to each other in the horizontal direction. This positional relationship ensures that a stable and uniform spatial structure is formed between the upper and lower tiles 2, which not only facilitates the installation and connection of the thermal break bridge 7, but also ensures that the entire PVC roofing sheet is subjected to balanced forces in the horizontal direction.

[0029] Finally, see Figure 4In this embodiment, when multiple PVC roof tiles are spliced ​​together, the high-wavelength 4 sides of adjacent upper tiles 1 are attached to each other, and the high-wavelength 4 sides of adjacent lower tiles 2 are also attached to each other. This splicing method makes the PVC roof tiles form a tight connection in the longitudinal direction, which enhances the continuity and integrity of the entire roof covering structure. The attachment of adjacent high-wavelength 4 sides not only helps to disperse the pressure on the roof, but also plays a role in waterproofing and drainage to a certain extent. Rainwater and other liquids can flow smoothly down along the attached high-wavelength 4 sides to avoid leakage.

[0030] Working principle:

[0031] For this high-strength, high-wave PVC roofing tile, in the roof construction area, pick up a lower tile 2 from the starting position and place its flat section 3 roughly parallel to the roof base layer, ensuring the high-wave section 4 of the lower tile 2 aligns with the pre-reserved installation space in the adjacent position. Using suitable fixing tools (such as an electric screwdriver with self-tapping screws), fix the lower tile 2 to the roof base layer (such as purlins) through the pre-drilled mounting holes on the edges of the high-wave section 4 and flat section 3. Install subsequent lower tiles 2 in sequence, always keeping the flat sections 3 of adjacent lower tiles 2 parallel and the sides of the high-wave sections 4 in contact. Check the position for accuracy after each tile is installed. Evenly apply sealant (such as waterproof sealant) to the upper groove 6 of the installed lower tile 2 to increase the connection seal. Pick up the thermal break 7 and accurately insert one end into the upper groove 6 of the lower tile 2, ensuring a secure insertion and correct position. Follow this method to... Install thermal break bridges 7 in the upper slots 6 of all lower tiles 2. Place the upper tiles 1 on top of the lower tiles 2 with the thermal break bridges 7 installed, ensuring that the lower slots 5 of the upper tiles 1 are precisely aligned with the other end of the thermal break bridges 7. Gently press the upper tiles 1 to ensure a tight fit. Check if the high-wave sections 4 of the upper and lower tiles 2 are aligned vertically and if the flat sections 3 are parallel. Then, use a fixing tool to pass through the mounting holes on the edges of the high-wave sections 4 and flat sections 3 of the upper tiles 1 to fix the upper tiles 1 to the roof base. The fixing method is the same as when installing the lower tiles 2. When installing subsequent PVC roof tiles, ensure that the sides of the high-wave sections 4 of adjacent upper tiles 1 and adjacent lower tiles 2 are tightly fitted together. Apply sealant to the joints to enhance the waterproofing effect. Then, use a fixing tool to add fixing points at the edges of the high-wave sections 4 and flat sections 3 at the joints, so that the entire roof PVC roof tiles are connected into a stable whole.
