Description

Technical Field

[0001] This application relates to the field of metal roofing tiles, and more particularly to a noise-reducing and sound-insulating metal roofing tile. Background Technology

[0002] Metal roofing tiles refer to those that replace glazed tiles, clay tiles, cement tiles, asphalt shingles, resin tiles, etc. Metal roofing tiles are classified according to their manufacturing process into stone-faced metal roofing tiles, painted metal roofing tiles, and unpainted metal roofing tiles.

[0003] The metal tiles are made of alloy metal as the base material and are manufactured by stamping or rolling. Then, other auxiliary materials are added to the surface of the base material to enhance the performance of the metal tiles.

[0004] During use, metal roofing tiles generate significant noise when impacted by rainwater, as the base material is metal.

[0005] In existing technologies, although a sound insulation layer is installed on the side of the substrate closest to the roof to reduce noise generation, during the installation of metal roofing tiles, the metal roofing tiles directly contact the frame on the roof, and there is no buffer layer between the metal roofing tiles. Finally, the metal roofing tiles are fixed to the frame with screws. The noise generated by the impact and vibration of the metal roofing tiles will be directly transmitted to the roof through the frame, resulting in the noise reduction effect of the metal roofing tiles being less than ideal.

[0006] Therefore, how to design a metal tile with improved noise reduction capability has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] This application provides a noise-reducing and sound-insulating metal tile to at least solve the above-mentioned technical problems existing in the prior art.

[0010] The positioning baffle is integrally formed with the substrate and bent along the thickness direction of the substrate to connect with the roof frame.

[0011] The buffer pad is set parallel to the roof. One end of the buffer pad is connected to the limiting edge, and the other end of the buffer pad is located between the positioning edge and the roof frame. A sound-absorbing cavity is formed between the buffer pad and the base plate.

[0012] Sound-absorbing cotton is filled inside the sound-absorbing cavity to absorb noise generated by the vibration of the substrate.

[0013] In one embodiment, a snap-fit ​​groove is provided on the limiting stop edge, and a rubber strip is snapped into the snap-fit ​​groove. Part of the rubber strip extends out of the snap-fit ​​groove and abuts against the limiting slope of another metal tile.

[0015] In one embodiment, the sound-absorbing cotton is provided with a plurality of sound-absorbing holes, which are arranged perpendicular to the roof direction.

[0016] In one embodiment, a sealing plate is also included, which is perpendicular to the roof and is installed between the buffer pad and the base plate to seal the sound-absorbing cotton in the sound-absorbing cavity.

[0017] In one embodiment, a sound insulation board is provided between the sound-absorbing cotton and the cushioning pad.

[0018] In one embodiment, a colored stone layer is included, which is installed on a substrate on the side away from the roof.

[0038] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] In this embodiment, the main product introduced is colored stone metal tile, such as... Figure 1 and Figure 2 As shown, the metal tile includes a base plate 1, wherein the base plate 1 is made of alloy material, and the base plate 1 is provided with a limiting inclined surface 11 and a limiting edge 12. Specifically, the limiting inclined surface 11 and the limiting edge 12 are arranged along the tilt direction of the roof. The limiting inclined surface 11 is close to the ridge of the roof and is inclined and extends away from the roof. The limiting edge 12 is located away from the ridge of the roof and is inclined and extends towards the roof.

[0040] Specifically, during the installation of the metal tiles, the limiting edge 12 of one metal tile abuts against the limiting slope 11 of another metal tile, thereby restricting the metal tile from sliding along the direction of the roof's inclination. It is worth noting that after the limiting edge 12 of one metal tile abuts against the limiting slope 11 of another metal tile, screws are needed to secure the two metal tiles together.

[0041] Under normal circumstances, the substrates 1 of the metal tiles are in contact with each other. When one metal tile is impacted and vibrates, the vibration energy is transferred to the other metal tile, causing the vibration to spread and resulting in increased noise. Therefore, if... Figure 2 As shown, rubber strips 2 are installed on the limiting inclined surface 11 and / or the limiting stop 12. The rubber strips 2 are used to block the two metal tiles, attenuate the vibration of the metal tiles, and reduce the spread of noise from the metal tiles due to vibration over a large area.

[0042] In this embodiment, specifically, the rubber strip 2 is installed on the limiting edge 12, and the rubber strip 2 is set parallel to the direction of the roof ridge.

[0043] To achieve the installation of rubber strip 2, as follows: Figure 2 and Figure 5 As shown, a snap-fit ​​groove 121 is bent out on the limiting edge 12, wherein the rubber strip 2 is inserted into the snap-fit ​​groove 121, and part of the rubber strip 2 extends out of the snap-fit ​​groove 121 to abut against the limiting inclined surface 11 of another metal tile, thereby separating the two metal tiles.

[0044] Normally, metal roofing tiles are directly installed on the roof frame. The base plate 1 of the metal roofing tile is fixed to the frame with screws. Vibrations generated by the base plate 1 can be directly transmitted to the roof frame, resulting in a decrease in the noise reduction effect of the metal roofing tile. Therefore, in this embodiment, as... Figure 1 and Figure 3 As shown, it also includes a buffer pad 3, which is installed between the base plate 1 and the roof. One side of the buffer pad 3 is connected to the base plate 1, and the other side of the buffer pad 3 is connected to the frame on the roof to attenuate the energy generated by the vibration of the metal tile and improve the noise reduction effect of the metal tile.

[0045] To achieve the installation of cushioning pad 3, as follows: Figure 2 and Figure 5As shown, the limiting edge 12 bends out to form an insertion groove 122, the buffer pad 3 is set parallel to the roof, and one side of the buffer pad 3 is inserted into the insertion groove 122. Specifically, the distance between the insertion groove 122 and the roof is greater than the distance between the fastening groove 121 and the roof.

[0046] like Figure 2 and Figure 5 As shown, the base plate 1 is bent to form a positioning stop 13 on the side away from the limiting stop 12. The positioning stop 13 is bent towards the side closer to the roof. A positioning plate 131 parallel to the roof is also bent on the positioning stop 13. The positioning plate 131 can be fixed to the frame on the roof with screws. The buffer pad 3 abuts against the side wall of the positioning plate 131 near the roof.

[0047] A sound-absorbing cavity 14 is formed between the buffer pad 3 and the substrate 1. In order to reduce the noise generated by the vibration of the substrate 1, in this embodiment, the sound-absorbing cavity 14 is filled with sound-absorbing cotton 4. One side wall of the sound-absorbing cotton 4 abuts against the substrate 1, and the other side wall of the sound-absorbing cotton 4 abuts against the buffer pad 3. The sound-absorbing cotton 4 supports the substrate 1, reducing the large-amplitude vibration of the substrate 1 caused by impact, thereby reducing the generation of noise. At the same time, as Figure 3 As shown, the sound-absorbing cotton 4 is also provided with several sound-absorbing holes 41. The sound-absorbing holes 41 are set perpendicular to the roof. The sound-absorbing holes 41 on the sound-absorbing cotton 4 can attenuate noise and achieve a certain noise reduction effect.

[0048] To further improve the noise reduction capability of the metal tile, in this embodiment, such as Figure 3 and Figure 6 As shown, it also includes a sound insulation board 6, which is installed between the sound-absorbing cotton 4 and the buffer pad 3. The sound insulation board 6 is used to block noise from being transmitted to one side of the roof, thereby further improving the noise reduction effect.

[0049] Specifically, in this embodiment, such as Figure 3 , Figure 4 and Figure 6 As shown, it also includes two sealing plates 5 perpendicular to the roof, wherein the sealing plates 5 are installed between the base plate 1 and the buffer pad 3, and the sound-absorbing cotton 4 is encapsulated in the sound-absorbing cavity 14.

[0050] In this arrangement, the sealing plate 5 and the buffer pad 3 are fixedly installed. After the base plate 1 of the metal tile is stamped and formed, in order to encapsulate the metal tile, the buffer pad 3 is first laid flat on the ground. Then, the sound insulation plate 6 and the sound-absorbing cotton 4 are placed between the two sealing plates 5. Then, one side of the buffer pad 3 is inserted into the insertion groove 122. The buffer pad 3 can be pushed down from one side of the metal tile to the base plate 1, thereby realizing the assembly of the buffer pad 3, the sound-absorbing cotton 4 and the base plate 1.

[0051] In the conventional process of preparing colored stone metal tiles, colored stones are sprinkled on top of a substrate 1, and then the colored stones are sintered. The colored stones are bonded to the substrate 1 under the action of acrylate, thus completing the preparation of colored stone metal tiles.

[0052] In conventional colored stone metal roofing tiles, the colored stone layer 7 is in direct contact with the substrate 1 without any buffer. When it rains, the impact energy of rainwater on the colored stone layer 7 is directly transferred to the substrate 1, easily causing vibration of the substrate 1 and thus generating noise. In this case, such as... Figure 3 and Figure 4 As shown, a buffer layer 8 is installed between the colored stone layer 7 and the substrate 1. The buffer layer 8 can be replaced by rubber or foam to buffer and dampen the shock, initially attenuating the energy of external impacts and reducing the vibration amplitude of the substrate 1.

[0053] Since the conventional colored stone layer 7 is sintered directly on the substrate 1 at a high temperature, and the buffer layer 8 of the metal tile is made of foam or rubber, the buffer layer 8 is prone to melting at high temperatures. Therefore, this solution makes some improvements to the production process of the metal tile. First, the colored stone layer 7 is sintered on the mold of the metal tile. After the substrate 1 is assembled with the buffer pad 3 and the sound-absorbing cotton 4, the colored stone layer 7 and the buffer layer 8 are installed on the substrate 1. The buffer layer 8 can be bonded to the substrate 1 and the colored stone layer 7 with acrylic ester.

[0054] Due to limitations in the material of the buffer layer 8, it is prone to aging under the influence of sunlight, rainwater erosion, and other factors. Therefore, in this embodiment, as... Figure 3 and Figure 4 As shown, the buffer layer 8 is wrapped with a polytetrafluoroethylene film 9, and then the polytetrafluoroethylene film 9 is bonded to the colored stone layer 7 and the substrate 1 by acrylate to realize the preparation of the metal tile.
