Description

Technical Field

[0001] This utility model belongs to the field of extruded polystyrene board technology, and particularly relates to a solid extruded polystyrene board. Background Technology

[0002] In existing technologies, traditional reinforcing members and the extruded polystyrene board substrate mainly rely on adhesives or physical pressing, which can easily lead to delamination due to temperature changes and long-term pressure. At the same time, there are often perforated holes between the reinforcing members and the extruded polystyrene board, and stress concentration areas are formed at the edges of the perforated holes. Under temperature cycling or long-term pressure, the adhesive or pressing points at the interface around the holes will fail first. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a solid extruded polystyrene board that can solve the aforementioned technical issues.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A solid extruded polystyrene (XPS) board includes a board body, and the solid XPS board further includes at least one reinforcing member distributed along the long axis of the board body and located at the center of the thickness of the board body. The reinforcing member is embedded inside the board body. Two surfaces of the reinforcing member in the thickness direction are respectively provided with a plurality of reinforcing ribs extending along the thickness direction of the board body. The reinforcing ribs and the reinforcing member are distributed at an angle, the angle being any one of acute angle, right angle, and obtuse angle. The plurality of reinforcing ribs are parallel to or at an angle to the long axis side surface of the board body. A groove is formed between two adjacent reinforcing ribs. The board body has a contoured embedding part embedded in the groove.

[0006] Furthermore, the reinforcing ribs on one surface of the reinforcing member in the thickness direction and the reinforcing ribs on the other surface of the reinforcing member in the thickness direction are symmetrically distributed.

[0007] Furthermore, the reinforcing ribs located on one surface of the reinforcing member in the thickness direction and the reinforcing ribs located on the other surface of the reinforcing member in the thickness direction are staggered.

[0008] Furthermore, the reinforcing member is block-shaped, and the thickness of the reinforcing member is greater than the thickness of the reinforcing rib.

[0009] Furthermore, in the length direction of the plate, the length of the reinforcing member is equal to the length of the reinforcing rib, and the length of the reinforcing member is equal to the length of the plate.

[0010] Furthermore, the reinforcing member also includes several fixing grooves, which are distributed along the axial direction of the reinforcing rib.

[0011] Furthermore, the reinforcing member is either a high-strength engineering plastic reinforcing member or a fiber composite reinforcing member.

[0012] Furthermore, the reinforcing member has one or more combined structures, such as block or mesh.

[0013] Furthermore, the reinforcing ribs provided on one surface of the plate and distributed at an angle to the long axis side surface of the plate and the reinforcing ribs provided on the other surface of the plate have the same inclination direction.

[0014] Furthermore, the reinforcing ribs located on one surface of the plate and distributed at an angle to the long axis side surface of the plate have opposite inclination directions to the reinforcing ribs located on the other surface of the plate.

[0015] Compared with existing technologies, the advantages of this application are: the reinforcing member is solidly fixed to the plate body, and a reinforcing rib is provided on the reinforcing member. The mechanical interlocking structure formed by the reinforcing rib and the conformal embedding part of the plate body completely replaces the unstable bonding that relies on adhesives in the traditional way, resulting in higher strength and longer service life of the extruded board.

[0034] Example 1

[0035] like Figures 1-2 As shown, a solid extruded polystyrene (XPS) board includes a board body 1 and at least one reinforcing member 2 distributed along the longitudinal axis of the board body 1. The reinforcing member 2 is embedded inside the board body 1, and at least one surface of the reinforcing member 2 in the thickness direction is provided with a plurality of reinforcing ribs 21 extending along the board body 1, such as... Figure 11 As shown, the reinforcing ribs 21 and the reinforcing members 2 are distributed at an angle, which can be any one of acute, right, and obtuse angles. Adjacent reinforcing ribs 21 form a... Figures 9-10 The groove 22 shown, and the conformal embedding part 11 embedded in the groove 22 inside the plate 1, greatly increase the contact area and bonding strength between the reinforcing member 2 and the plate 1, effectively resisting the relative slippage or separation of the two under the action of force (especially shear force and peeling force), and significantly improving the overall stiffness and load-bearing capacity of the composite structure.

[0036] The aforementioned reinforcing member 2 is a high-strength engineering plastic sheet or fiber-reinforced composite material sheet. Compared to traditional metal reinforcing members (such as steel plates), engineering plastic and composite material sheets provide the same or even higher tensile / bending strength while reducing density. This allows the final sheet to significantly reduce its weight while maintaining excellent mechanical properties, thereby reducing transportation and construction costs.

[0037] Furthermore, as a preferred embodiment, the reinforcing member 2 has one or more combined structures, such as block or mesh. Figures 3-4 As shown, when the reinforcing member 2 is block-shaped, it mainly provides high strength and high stiffness along its planar direction, making it particularly suitable for applications requiring resistance to bending loads; such as Figures 5-6 As shown, when the reinforcing member 2 is mesh-like, this structure provides excellent isotropic reinforcement and superior tear and impact resistance, while maintaining good flexibility.

[0038] The thickness of the reinforcing member 2 is greater than the thickness of the reinforcing rib 21. In the length direction of the plate 1, the length of the reinforcing member 2 is equal to the length of the reinforcing rib 21, and the length of the reinforcing member 2 is equal to the length of the plate 1.

[0039] Specifically, such as Figures 9-10As shown, several reinforcing ribs 21 are provided on both surfaces of the reinforcing member 2 in the thickness direction. And the following two schemes are available:

[0040] I. For example Figure 9 As shown, the reinforcing ribs 21 on one surface of the reinforcing member 2 in the thickness direction and the reinforcing ribs 21 on the other surface of the reinforcing member 2 in the thickness direction are symmetrically distributed. The symmetrically distributed ribs and the grooves formed therein make the contoured embedding parts 11 formed on the upper and lower surfaces of the plate 1 substrate also symmetrical. When the plate is subjected to bending load, the tensile and compressive strains on the upper and lower surfaces can be coordinated more evenly, which significantly improves the overall bending stiffness and bending strength of the plate and reduces bending deformation.

[0041] II. Figure 10 As shown, the reinforcing ribs 21 on one surface of the reinforcing member 2 in the thickness direction and the reinforcing ribs 21 on the other surface of the reinforcing member 2 in the thickness direction are staggered; the staggered reinforcing ribs 21 and the groove structure 22 can more effectively hinder the propagation path of cracks in the plate or inside the plate. When subjected to shear force or impact force, the load is distributed in more directions, significantly improving the shear strength, toughness and impact resistance of the plate.

[0042] As an alternative, in this embodiment, the aforementioned reinforcing ribs 21 can also be distributed at an angle along the long axis of the plate 1, such as... Figures 7-8 The diagram shows a new assembly scheme for the reinforcing rib 21 and the reinforcing member 2, the effect of which is the same as the parallel scheme described above (e.g. Figures 3-4 The effect is the same as shown.

[0043] And several reinforcing ribs 21 are distributed parallel to or at an angle to the long axis side of the plate 2, and have the following two schemes:

[0044] 1. The reinforcing ribs located on one surface of the plate and distributed at an angle to the long axis side of the plate, and the reinforcing ribs located on the other surface of the plate, have the same inclination direction. This arrangement helps resist the overall bending deformation of the plate, especially in terms of bending stiffness in the long axis direction, effectively preventing excessive downward deflection or upward arching of the plate, thereby improving the reliability and load-bearing capacity of the fixed connection.

[0045] Second, the reinforcing ribs located on one surface of the plate and distributed at an angle to the long axis side of the plate, and the reinforcing ribs located on the other surface of the plate, have opposite inclination directions. This reverse inclination structure greatly enhances the plate's resistance to torsional loads and its ability to resist complex combined loads (such as bending + torsion).

[0046] As a multiple-choice option, such as Figures 12-13As shown, the reinforcing member 2 also includes several fixing grooves 23, which are distributed along the axial direction of the reinforcing rib 21. Their function is to significantly improve the axial fixing strength between the reinforcing member 2 and the plate 1.

[0047] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
