AI Technical Summary
Conventional bamboo boards are prone to cracking during thermal expansion, cold shrinkage, tidal shrinkage, drying, and shrinkage, which affects product quality. The wave-shaped structure of existing anti-cracking bamboo boards causes the upper and lower layers to be unable to fit, and more glue needs to be filled, resulting in uneven colloid thickness.
The bamboo board combination with triangular zigzag structure is used to increase the strength and adhesion stability of the bamboo board and reduce the risk of cracking through the interlaced arrangement of the first group of plates, the second group of plates and the use of mesh fiber layers.
It effectively reduces the amount of material removed by bamboo sheets, improves the generation rate of bamboo to bamboo boards, ensures the consistency of the thickness of the adhesive layer between each group of boards, has good connection stability, reduces the risk of cracking, and improves the durability of bamboo boards.

[0030] Example 1, see Figure 1-2 :
[0031] The present application provides a crack-proof bamboo board, comprising a first set of boards 1, a second set of boards 2 and a third set of boards 3, wherein the first set of boards 1, the second set of boards 2 and the third set of boards 3 are connected in sequence. The bottom cross section of the first set of boards 1 and the top cross section of the second set of boards 2 are correspondingly arranged in a triangular sawtooth shape, and the triangular tips 40 at the bottom of the first set of boards 1 and the triangular tips 40 at the top of the second set of boards 2 are arranged alternately.
[0032] The first group of boards 1 and the second group of boards 2 are both formed by bonding a number of transversely arranged anticorrosion bamboo sheets 4 in sequence, the top of the anticorrosion bamboo sheet 4 is set as a plane, the two side surfaces of the anticorrosion bamboo sheet 4 are set as splicing planes 42, and the bottom of the anticorrosion bamboo sheet 4 is set as a triangular protrusion 43. The splicing planes 42 of two adjacent anticorrosion bamboo sheets 4 are bonded to each other, so that a number of horizontally arranged triangular protrusions 43 form a triangular serrated shape.
[0033] Specifically, the top of the triangular protrusion is a triangular tip 40, and there is a recess 41 between two adjacent triangular protrusions 43. The triangular tips 40 at the bottom of the first set of plates 1 are staggered and embedded in the recess 41 at the top of the second set of plates 2, and the triangular tips 40 at the top of the second set of plates 2 are staggered and embedded in the recess 41 at the bottom of the first set of plates 1, so that the first set of plates 1 and the second set of plates 2 fit each other.
[0034] Preferably, another anticorrosive bamboo sheet 4 is vertically divided into two half bamboo sheets 44, and the two half bamboo sheets 44 are respectively arranged on one side of the first group of boards 1 and the other side of the second group of boards 2, so that both sides of the anti-cracking bamboo board are flush.
[0035] It can be understood that the anti-corrosion bamboo chips 4 are made of bamboo chips that have been treated with anti-corrosion. Common anti-corrosion treatments include soaking the bamboo chips in a sodium silicate solution, taking them out and draining them, and then heating and curing them to make anti-corrosion bamboo chips 4. The interior of the anti-corrosion bamboo chips 4 is filled with sodium silicate and cured, making the structure of the anti-corrosion bamboo chips 4 more uniform and dense, playing a waterproof role, with good durability and not easy to crack.
[0036] As an embodiment, the cross section of the triangular protrusion 43 is set to be an isosceles triangle. It is understandable that due to the characteristics of bamboo itself, after the bamboo is cut into segments, strips and processed into bamboo chips, the bamboo chips have a curved surface before the surface material is planed off. Planing the curved surface to form the triangular protrusion 43 is conducive to reducing the planed material, making full use of the bamboo, and facilitating the processing and preparation of the antiseptic bamboo chips 4.
[0037] As an embodiment, the third set of panels 3 is formed by sequentially bonding a plurality of third bamboo pieces 30 arranged longitudinally, and the top and both sides of the third bamboo piece 30 are arranged as planes. Preferably, the bottom of the third bamboo piece 30 is also arranged as a plane.
[0038] A first mesh fiber layer 5 is arranged between the bottom of the first group of panels 1 and the top of the second group of panels 2, and both sides of the first mesh fiber layer 5 are coated with viscose. A second mesh fiber layer 6 is arranged between the bottom of the second group of panels 2 and the top of the third group of panels 3, and both sides of the second mesh fiber layer 6 are coated with viscose. The mesh fibers can provide a certain tensile force in different directions due to the particularity of their structure. The first group of panels 1, the first mesh fiber layer 5, the second group of panels 2, the second mesh fiber layer 6 and the third group of panels 3 are bonded together by the viscose, and the bonding stability is good, which is beneficial to improving their tensile and anti-cracking properties.
[0039] The present application also provides a spliced desktop panel, the spliced desktop panel includes the anti-cracking bamboo board as described in any embodiment, and the number of the anti-cracking bamboo boards is at least two. Preferably, adjacent anti-cracking bamboo boards are connected by a board connector, and adhesive is applied to the connecting side of the anti-cracking bamboo boards. Specifically, if the board connector adopts a hidden connector, a mounting hole or mounting groove is correspondingly opened on the connecting side.
[0040] Example 2, see Figure 3 :
[0041] Repeat Example 1, but a plurality of through holes 20 are arranged on the second group of plates 2, and sockets 70 are provided at the bottom of the first group of plates 1 and the top of the third group of plates 3 respectively corresponding to the through holes 20, and limiting columns 7 are installed in the through holes 20, and the tops of the limiting columns 7 are correspondingly embedded in the sockets 70 of the first group of plates 1, and the bottoms of the limiting columns 7 are correspondingly embedded in the sockets 70 of the third group of plates 3.
[0042] As an implementation manner, the outer side of the limiting column 7 is coated with a rubber layer, and the rubber layer plays a buffering role.
[0043] As an embodiment, the socket 70 is a non-through hole 20. Specifically, the depth of the socket 70 arranged on the third group of boards 3 does not exceed half of the thickness of the third group of boards 3, and the depth of the socket 70 arranged on the first group of boards 1 does not exceed half of the thickness of the first group of boards 1.
[0044] As an implementation manner, the through holes 20 are evenly distributed on the second group of plates 2 .
[0045] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
