Embodiment 1

[0041] Example 1 Zigzag inner core lightweight wood-based panel

[0042] Such as figure 1 with figure 2 As shown, the zigzag inner core lightweight wood-based panel is composed of a surface panel 1, a vertical partition 2, a support piece 3 and a surrounding panel 4.

[0043] The wood-based panel has two upper and lower surface panels 1, and the distance between the upper and lower two surface panels 1 is 15-600mm. Such as image 3 with Figure 4 As shown, a plurality of parallel shallow grooves 101 are opened on the surface plate 1 , and the cross section of the shallow grooves can be square 101 , trapezoidal 102 or nearly triangular 103 . The distance between two adjacent shallow grooves is 50-600mm. Such as Figure 5 with Image 6 As shown, the two edges of the vertical partition 2 have protrusions 201 that match the shape of the shallow groove, and the protrusions on both sides of the vertical partition are inserted into the shallow groove, and are fixedly connecte...

Embodiment 2

[0047] The preparation of embodiment 2 zigzag inner core lightweight wood-based panel

[0048] Figure 11 Shown is the flow chart for the preparation of the zigzag inner core lightweight wood-based panel described in Example 1. The preparation steps are as follows:

[0049] 1. Plate processing

[0050] (1) Surface processing

[0051] Process the surface board substrate according to the set thickness, width and length. The thickness of the surface plate is 2mm-12mm.

[0052] (2) Vertical clapboard processing

[0053] Process wood / bamboo slats with the same length, width and thickness as vertical partitions, the length of the vertical partitions is the same as the width of the front panel, and the width of the vertical partition is the same as the distance between the wood-based panel and the lower panel. Such as Image 6 As shown, a convex part 201 with a trapezoidal 202 or nearly triangular 201 cross-section can be machined on the two edges of the vertical partition 2 a...

Embodiment 3

[0076] The fir hollow door panel of embodiment 3 zigzag inner core

[0077] Using fir boards and fir strips, hollow boards were prepared according to the method in Example 2.

[0078] The upper and lower panels are made of fir boards, the size is: 200cm×100cm×0.5cm, the density ρ=0.5g / cm 3 .

[0079] The fir strips are made into vertical partitions, the size is: 200cm×5cm×1cm.

[0080] The fir strips are made into supporting pieces, and the size is: 42.42cm×5cm×0.5cm.

[0081] The fir strips are made into hoardings, the lengths are 200.5cm and 100.5cm, the width is 6cm, and the thickness is 0.5cm.

[0082] The fir board is made into a vertical support board, and the size is: 200cm×5cm×7cm.

[0083] Such as Figure 12 As shown, three vertical clapboards 2 are set between the upper and lower table plates, and the distance between the vertical clapboards is 30cm. The support pieces 3 are arranged in a zigzag shape between the vertical partitions 2, and the most end support ...

Abstract

The invention discloses a light artificial board with a zig-zag inner core and a preparation method thereof. The artificial board is composed of face boards, vertical partition boards, supporting sheets and surrounding boards. The artificial board is provided with the upper face board and the lower face board; and the plurality of parallel vertical partition boards are arranged between the two face boards, the board surfaces of the vertical partition boards are perpendicular to the board surfaces of the face boards, and the two sides of the vertical partition boards are fixedly connected withthe two face boards correspondingly. The supporting sheets are arranged in a 'zigzag' shape between every two adjacent vertical partition boards, the supporting sheets are perpendicular to the face boards, and the two ends of the supporting sheets are fixedly connected with the vertical partition boards. Gaps around the periphery of the upper and lower face boards are covered with the surroundingboards. The connection among the parts mainly adopts mortise and tenon structures, the material used by the artificial board is small, the inner space of the board is large, the structure is firm, andthe artificial board has the advantages of small weight, high strength and good sound insulation and heat insulation performance. The preparation method of the light artificial board is simple, and large-scale batch production is facilitated.

Description

technical field [0001] The invention relates to a hollow artificial board, which belongs to the technical field of building materials. Background technique [0002] In interior decoration and furniture preparation, thick door panels, wall panels or decorative panels are used. If solid core panels are used, not only the weight is heavy, but also the solid wood panels are easy to warp, deform or crack. The above-mentioned defects can be overcome. At present, there are also hollow boards on the market, such as hollow particle boards and hollow boards with honeycomb paper in the middle. The strength of the boards prepared by these materials is not high. For example, the utility model patent with the application number of 200420102013 (CN2769008Y [Chinese])) discloses a light-weight wood-based panel, which is bonded into one by three layers of a panel, a bottom plate and a central layer, and the central layer is located between the panel and the bottom plate. The center layer is...
