Description

Technical Field

[0001] The utility model relates to the field of building materials, in particular to a glass fiber cement board. Background Art

[0002] Glass fiber cement board is a board made of glass fiber and cement slurry. It not only has excellent tensile and impact resistance, but also has the advantages of good crack resistance, light weight, good moldability, easy processing, moisture resistance, and non-flammability. Among the existing glass fiber cement boards, there is a technical solution with a patent application number of 202321759124.9 and the name of "A Fiber Cement Board" that the applicant has applied for to the State Intellectual Property Office of China. The solution mainly includes a fiber cement board body with a metal sheet embedded in it, and the metal sheet is provided with a number of large through holes and small through holes with punched flanges. In this way, the impact resistance of the fiber cement board body in the horizontal direction can be enhanced by setting the punched flanges, so that the upper and lower cement layers of the fiber cement board body are not prone to fracture and disintegration. However, in actual application, it still has the following shortcomings:

[0003] Because the metal sheet is a single, horizontal, straight plate, the horizontal impact resistance of the fiber cement board is achieved solely by the perforated flanges. Furthermore, the height of the perforated flanges is limited by the aperture size. The larger the aperture, the higher the perforated flange height. However, the larger the aperture, the lower the overall structural strength of the metal sheet, which in turn affects the overall structural strength of the fiber cement board. To ensure the fiber cement board has superior structural strength, the aperture must be kept small, which limits the height of the perforated flanges. Consequently, the metal sheet can only be used to produce thinner fiber cement boards. If used to produce thicker fiber cement boards, the impact resistance provided by the perforated flanges becomes negligible, making the thicker fiber cement boards susceptible to fracture and disintegration after horizontal impacts.

[0004] Therefore, in view of the above-mentioned shortcomings of the aforementioned glass fiber cement board, it is very necessary to redesign its structure to better meet people's application needs. Utility Model Content

[0005] The purpose of the present invention is to solve the above-mentioned problems and shortcomings and to provide a glass fiber cement board. The glass fiber cement board utilizes the corrugated shape of the corrugated board to enhance the horizontal impact resistance of the glass fiber cement board body, and by making the distance H from the top edge to the bottom edge of the corrugated board greater than the thickness of the horizontal straight board, the metal plate can be used to produce a thicker glass fiber cement board body. At the same time, by arranging vertical perforations and horizontal perforations, the upper and lower cement layers of the glass fiber cement board body can be provided with a fusion connection in both the horizontal and vertical directions, so that the internal structure strength is higher, and the glass fiber cement board body can be prevented from being fractured and falling apart.

[0006] The technical solution of the present utility model is achieved as follows: a glass fiber cement board, including a glass fiber cement board body with a metal plate embedded therein, wherein the metal plate is composed of a plurality of horizontal straight plates and a corrugated plate connected between each two adjacent horizontal straight plates, and the distance H from the top edge to the bottom edge of the corrugated plate is greater than the thickness of the horizontal straight plate; the horizontal straight plates are provided with a plurality of vertical perforations arranged along the length direction thereof, and the corrugated plates are provided with a plurality of horizontal perforations arranged along the length direction thereof and horizontally penetrating the side walls thereof.

[0007] Preferably, the corrugated plate is composed of a plurality of inverted U-shaped portions and a U-shaped portion connected between every two adjacent inverted U-shaped portions, and each transverse perforation is arranged to transversely penetrate the inverted U-shaped portion and the side wall of the U-shaped portion.

[0008] Preferably, vertical through holes are respectively provided on the top surface of the inverted U-shaped portion and the bottom surface of the U-shaped portion.

[0009] Preferably, a punching flange is further provided at the edge of the vertical through hole, the punching flange of the inverted U-shaped portion is folded upward, and the punching flange of the U-shaped portion is folded downward.

[0010] Preferably, the thickness of the metal plate is 0.2-1 mm.

[0011] The beneficial effects of the present invention are as follows: By arranging a corrugated plate between each two adjacent horizontal straight plates, the present invention can utilize the corrugated shape of the corrugated plate to enhance the horizontal impact resistance of the glass fiber cement board body inside the glass fiber cement board body, thereby avoiding the occurrence of fractures and disintegration of the glass fiber cement board body. Furthermore, by making the distance H from the top edge to the bottom edge of the corrugated plate greater than the thickness of the horizontal straight plate, the metal plate can be used to produce glass fiber cement board bodies with thicker thickness. At the same time, by arranging vertical perforations and horizontal perforations, the upper and lower cement layers of the glass fiber cement board body can be provided with fusion connections in both the horizontal and vertical directions, which not only improves the integrity of the glass fiber cement board body, but also further improves its horizontal impact resistance, makes its internal structure stronger, and avoids the occurrence of fractures and disintegration of the glass fiber cement board body.

[0015] like Figure 1 As shown, the glass fiber cement board described in the present invention includes a glass fiber cement board body 1 with a metal plate 2 embedded therein. In order to achieve the purpose proposed by the present invention, as shown in FIG. Figure 2 and Figure 3 As shown, the metal plate 2 is composed of a plurality of horizontal straight plates 21 and a corrugated plate 22 connected between each two adjacent horizontal straight plates 21, and the distance H from the top edge to the bottom edge of the corrugated plate 22 is greater than the thickness of the horizontal straight plate 21; the horizontal straight plate 21 is provided with a plurality of vertical perforations 211 arranged along its length direction, and the corrugated plate 22 is provided with a plurality of horizontal perforations 221 arranged along its length direction and horizontally penetrating its side wall. The present invention utilizes the corrugated shape of the corrugated plate 22 to enhance the horizontal impact resistance of the glass fiber cement board body 1, and by making the distance H from the top edge to the bottom edge of the corrugated plate 22 greater than the thickness of the horizontal straight plate 21, the metal plate 2 can be used to produce a thicker glass fiber cement board body 1. At the same time, by arranging vertical perforations 211 and horizontal perforations 221, the upper and lower cement layers of the glass fiber cement board body 1 can be provided with a fusion connection in both the horizontal and vertical directions, making the internal structure stronger and avoiding the occurrence of faults and disintegration of the glass fiber cement board body 1.

[0016] In order to further improve the structure of the corrugated plate 22, as Figure 3As shown, the corrugated sheet 22 is composed of a plurality of inverted U-shaped portions 222 and U-shaped portions 223 connecting each adjacent inverted U-shaped portion 222. Each transverse perforation 221 is provided transversely through the sidewalls of the inverted U-shaped portions 222 and the U-shaped portions 223. This facilitates the production of the corrugated sheet 22 and the provision of the transverse perforations 221 therein. In actual production, multiple corrugated sheets 22 can be stamped out of a single straight sheet through a press molding process, thereby forming multiple horizontal straight sheets 21 and corrugated sheets 22, respectively, from the same sheet. Furthermore, in practical applications, the distance H from the top to the bottom of the corrugated sheet 22 can be made slightly smaller than the thickness of the glass fiber cement board body 1 by stamping, depending on the desired thickness of the glass fiber cement board body 1. This ensures that, even with a relatively thick glass fiber cement board body 1, it maintains a highly reliable and excellent structural strength and excellent resistance to horizontal impacts.

[0017] In order to further improve the structural strength of the glass fiber cement board body 1, Figure 3 As shown, vertical through holes 224 are respectively provided on the top surface of the inverted U-shaped portion 222 and the bottom surface of the U-shaped portion 223. This can increase the area of ​​fusion connection and contact between the upper and lower cement layers of the glass fiber cement board body 1, thereby making its internal structural strength higher.

[0018] In order to further improve the horizontal impact resistance of the glass fiber cement board body 1, Figure 3 As shown, the edges of the vertical through holes 224 are further provided with perforated flanges 225. The perforated flanges 225 of the inverted U-shaped portion 222 are folded upward, while the perforated flanges 225 of the U-shaped portion 223 are folded downward. This not only enhances the structural strength of the glass fiber cement board body 1, but also enhances the horizontal impact resistance of the glass fiber cement board body 1, thereby further preventing the glass fiber cement board body 1 from fracturing or falling apart.

[0019] In order to ensure that the metal plate 2 can play a good structural reinforcement role on the glass fiber cement board body 1 while controlling the production cost, the thickness of the metal plate 2 is 0.2-1 mm. As an example, the thickness of the metal plate 2 is 0.8 mm.
