[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0024] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0025] Reference Figures 1 to 3 As shown, a Great Wall-shaped structural core material with vertical rib reinforcement grooves includes a plurality of linearly connected panel units 1, wherein the panel unit 1 includes a left inclined plate 11, an upper connecting plate 12, a right inclined plate 13 and a lower connecting plate 14 connected in sequence, the tops of the left inclined plate 11 and the right inclined plate 13 are connected through the upper connecting plate 12, and the bottoms of the left inclined plate 11 and the right inclined plate 13 extend in inclined directions away from each other; the lower connecting plate 14 is fixed to the bottom of the right inclined plate 13 and connected to the left inclined plate 11 of the adjacent panel unit 1; the left inclined plate 11 and the right inclined plate 13 are both protruded upward to form a plurality of protruding reinforcement strips 111 arranged in a linear array along the length direction of the panel unit 1. The upwardly protruding reinforcement strip 111 can improve the deformation resistance of the core material along the corrugation direction, enhance the bending resistance of the load-bearing section, and greatly improve the bending strength of the core material in the corrugation direction; when subjected to load or external force, the core material with vertical ribs has higher bending strength and smaller deflection than the core material without vertical ribs.

[0026] In addition, the left inclined plate 11 and the right inclined plate 13 are formed with a plurality of arrayed sound-absorbing holes 112, which are arranged staggered from the raised reinforcing strips 111. The sound-absorbing holes 112 are arranged staggered from the raised reinforcing strips 111, and the sound-insulating effect of the corrugated board can be enhanced by using the small hole sound-absorbing principle and structures such as sound-insulating cotton glued to the upper and lower ends of the core material. Preferably, the diameter of the sound-absorbing holes 112 is between 1 mm and 2 mm. The sound-absorbing holes 112 of this diameter give the corrugated board an excellent sound-insulating effect.

[0027] The spacing between adjacent raised reinforcement strips 111 (eg Figure 1 L1 in the figure) is between 15mm and 20mm. If the spacing of the raised reinforcement strips 111 is too sparse, the bending strength and flexural resistance of the core material will be reduced. If the spacing of the raised reinforcement strips 111 is too dense, the number of sound-absorbing holes 112 will be reduced, thereby reducing the sound absorption effect. In addition, since a large number of sound-absorbing holes 112 are provided on the left inclined plate 11 and the right inclined plate 13, the strength of the board surface will be reduced. By increasing the spacing of the raised reinforcement strips 111 that meet the above density, the core material can have good bending strength and flexural resistance and excellent sound insulation effect. In addition, the sound-absorbing holes 112 are provided on the inclined left inclined plate 11 and the right inclined plate 13, so that the sound waves can be refracted multiple times through the inclined surface, thereby extending the conduction path of the sound waves. When the sound waves outdoors pass through the extension of the conduction path, the intensity of the sound waves indoors can be reduced, thereby improving the sound insulation effect.

[0028] Preferably, the upper connecting plate 12 and the lower connecting plate 14 are also formed with a plurality of arrayed sound-absorbing holes 112. During processing and forming, firstly, stamping is performed on the flat plate, so that the flat plate is formed with raised reinforcement strips 111 and sound-absorbing holes 112 arranged in a certain pattern, and then the flat plate is bent by cold bending forming equipment to obtain a Great Wall-like structural core material with vertical rib reinforcement grooves of the utility model.

[0029] As a preference, the protrusion height of the protrusion reinforcement strip 111 (eg Figure 3 If the height of the raised reinforcing strip 111 is too high, the core material needs to be stamped with high strength during molding, which may easily cause the panel unit 1 to be over-stamped and damaged; if the height of the raised reinforcing strip 111 is too low, the bending strength and deflection resistance of the core material will be reduced.

[0030] The distance between the two ends of the raised reinforcement strip 111 and the upper connecting plate 12 and the lower connecting plate 14 (such as Figure 3 The contact area between the raised reinforcement strip 111 and the left inclined plate 11 and the right inclined plate 13 is extended as much as possible, thereby further improving the bending resistance, deflection resistance and load capacity of the core material.

[0031] The raised reinforcement strip 111 is arranged parallel to the cross-sectional direction of the panel unit 1 , so as to facilitate the processing and forming of the raised reinforcement strip 111 .

[0032] The left inclined plate 11 of the panel unit 1 at the leftmost edge is fixedly connected to the left bottom plate 2; the right inclined plate 13 of the panel unit 1 at the rightmost edge is fixedly connected to the right bottom plate 3; the left bottom plate 2 and the right bottom plate 3 are double-layer inwardly folded structures, and the bottom surfaces of the left bottom plate 2 and the right bottom plate 3 are flush with the lower connecting plate 14. The double-layer inwardly folded left bottom plate 2 and the right bottom plate 3 are supported on the bottom surface, thereby ensuring the bending resistance, deflection resistance and load capacity of the core material.

[0033] The core material is formed by bending an aluminum metal plate, and the thickness of the core material is between 0.2 mm and 0.4 mm.

[0034] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
