[0002] Wood-based panels are widely used in furniture and flooring. With increasing environmental awareness, the use of traditional natural wood is gradually decreasing, being replaced by various man-made composite panels. Composite panels are particularly prevalent in flooring.

[0003] Because wood flooring has a multi-layered structure, and these layers are mostly connected and fixed with glue, the boards are prone to cracking over time or under harsh conditions. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a crack-resistant board material.

[0005] The technical solution of this utility model is a crack-resistant board material, comprising:

[0006] The composite board body includes a flame-retardant layer, a buffer layer, and a bottom substrate, wherein the buffer layer is disposed between the flame-retardant layer and the bottom substrate; multiple annular grooves are formed on the outer periphery of the composite board body.

[0007] Multiple steel strips, one end of which is connected to a fixing head, and the other end of which has a groove that matches the fixing head. The fixing head has multiple protrusions, and the end of the steel strip has multiple matching grooves that match the protrusions.

[0008] Preferably, the upper and lower ends of the buffer layer are provided with multiple insert rods, the cross-section of the insert rods is a "T" shaped structure, and the flame retardant layer and the bottom substrate are provided with multiple slots that fit the insert rods.

[0009] Preferably, a waterproof surface layer is provided on the outer surface of the flame-retardant layer.

[0010] Preferably, the outer surface of the waterproof layer is provided with several anti-wear raised points.

[0011] Preferably, the thickness of the steel strip is the same as the thickness of the upper end of the annular groove, and the length of the steel strip is equal to the circumference of the annular groove.

[0012] Preferably, the inner surface of the waterproof surface layer is provided with multiple horizontal strips, the horizontal strips and the waterproof surface layer are integrally formed, and the flame retardant layer is provided with multiple horizontal grooves that match the horizontal strips.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: the steel strip is placed inside the annular groove, and the fixing head is glued to the inside of the groove with glue. Then, multiple protrusions are inserted into the inside of multiple matching grooves to achieve the limiting function. The steel strips connected end to end form a clamp structure to enhance the stability of the plate and reduce the probability of cracking of the plate. Attached Figure Description

[0018] Example 1

[0019] like Figures 1-3 As shown in the figure, the anti-cracking plate proposed in this embodiment includes a composite plate body and multiple steel strips 5.

[0020] The composite board body includes a flame-retardant layer 1, a buffer layer 2, and a bottom substrate 3. The buffer layer 2 is located between the flame-retardant layer 1 and the bottom substrate 3. Multiple annular grooves 8 are formed on the outer periphery of the composite board body. A waterproof surface layer 4 is provided on the outer surface of the flame-retardant layer 1. Multiple transverse strips are provided on the inner surface of the waterproof surface layer 4. The transverse strips and the waterproof surface layer 4 are integrally formed. Multiple transverse grooves that fit the transverse strips are formed on the flame-retardant layer 1. This arrangement is to increase the contact area at the bonding point between the waterproof surface layer 4 and the flame-retardant layer 1, thereby preventing delamination. Several anti-wear protrusions are provided on the outer surface of the waterproof surface layer 4.

[0021] One end of the steel strip 5 is connected to a fixing head 51, and the other end of the steel strip 5 is provided with a groove 501 that fits into the fixing head 51. The fixing head 51 is provided with multiple protrusions 511, and the end of the steel strip 5 is provided with multiple mating grooves 502 that fit into the multiple protrusions 511. The thickness of the steel strip 5 is the same as the thickness of the upper end of the annular groove 8, and the length of the steel strip 5 is equal to the circumference of the annular groove 8. This arrangement makes the upper end of the steel strip 5 flush with the upper end of the flame retardant layer 1, which helps to ensure the flatness of the upper end of the composite board body.

[0022] Specifically, the steel strip 5 is placed inside the annular groove 8, and the steel strip 5 has a certain degree of toughness. The fixing head 51 is pressed into the inside of the groove 501. Then, multiple protrusions 511 are inserted into the inside of multiple mating grooves 502 respectively. Before pressing, glue for bonding metal is dripped into the inside of the groove 501, thereby realizing the end-to-end connection of the steel strip 5. The steel strip 5 forms a clamp structure to enhance the stability of the plate and reduce the probability of cracking of the plate.

[0023] Example 2

[0024] like Figure 1-3 As shown in the figure, the anti-cracking plate proposed in this embodiment includes a composite plate body and multiple steel strips 5.

[0025] The composite board body includes a flame-retardant layer 1, a buffer layer 2, and a bottom substrate 3. The buffer layer 2 is located between the flame-retardant layer 1 and the bottom substrate 3. Multiple annular grooves 8 are formed on the outer periphery of the composite board body. A waterproof surface layer 4 is provided on the outer surface of the flame-retardant layer 1. Multiple transverse strips are provided on the inner surface of the waterproof surface layer 4. The transverse strips and the waterproof surface layer 4 are integrally formed. Multiple transverse grooves that fit the transverse strips are formed on the flame-retardant layer 1. This arrangement is to increase the contact area at the bonding point between the waterproof surface layer 4 and the flame-retardant layer 1, thereby preventing delamination. Several anti-wear protrusions are provided on the outer surface of the waterproof surface layer 4.

[0026] One end of the steel strip 5 is connected to a fixing head 51, and the other end of the steel strip 5 is provided with a groove 501 that fits into the fixing head 51. The fixing head 51 is provided with multiple protrusions 511, and the end of the steel strip 5 is provided with multiple mating grooves 502 that fit into the multiple protrusions 511. The thickness of the steel strip 5 is the same as the thickness of the upper end of the annular groove 8, and the length of the steel strip 5 is equal to the circumference of the annular groove 8. This arrangement makes the upper end of the steel strip 5 flush with the upper end of the flame retardant layer 1, which helps to ensure the flatness of the upper end of the composite board body.

[0027] Unlike Embodiment 1, in this embodiment, multiple insert rods 6 are provided at both the upper and lower ends of the buffer layer 2. The cross-section of the insert rod 6 is a "T" shaped structure. Multiple slots 7 that fit the insert rods 6 are provided on both the flame-retardant layer 1 and the bottom substrate 3. Specifically, by setting the above structure, the bonding area between two adjacent boards can be increased, and the cooperation between the slots 7 and the insert rods 6 limits the connection between the two layers, thereby further improving the crack resistance of the boards.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
