Detailed Description

The following will further describe the core intermediate structure of a composite board according to the present utility model in detail with reference to the accompanying drawings and specific examples, so as to provide a clearer understanding of the structural form and operation thereof, but not to limit the scope of the present utility model.

The core plate intermediate structure of the utility model is used as an important component of the composite board, and plays a role in supporting the main body strength and absorbing tiny deformation so as to reduce the integral deformation. We describe and claim it separately as an important structure.

For the composite board, the core board is arranged in the middle, the face plates are arranged on the upper surface and the lower surface, and the core board is clamped by the two face plates to form the whole of the composite board. Because the core adopts the solid wood material, if the panel adopts the solid wood material, the whole is the solid wood composite board, and the panel can also adopt non-solid wood board for more functions and decoration. But the core board is used as a solid wood support to form the main body material of the composite board.

In the process of preparing the solid wood composite board, the key point is the processing of the solid wood core board. In the process of processing the solid wood core plate, the core plate finished product is generally formed by normalizing the solid wood plate, preliminarily combining and processing the intermediate structure, attaching the surface and transversely cutting. The solid wood boards are processed into uniform specifications, and mainly have the same length and width specifications, and the thicknesses can be the same or different.

The intermediate structure of the composite board core board comprises an integrated material formed by a plurality of solid wood strips, wherein the cross section of the integrated material is square wood 1, the length and width specifications of the solid wood strips are the same, the upper surface and the lower surface of the solid wood strips are aligned and then are overlapped and formed into square wood 1, the width of the overlapped and formed square wood 1 is the width of the solid wood strips, the thickness is the integral thickness of the solid wood strips after being overlapped, and the thickness is slightly larger than the sum of the thicknesses of the solid wood strips due to the condition of glue bonding.

The composite board is made of a core board and a face board, and is a new composite material, wherein the core board comprises raw material boards, an intermediate structure and a core board finished product in the preparation process. After sawing and grooving the processed square timber, the intermediate body 2 is formed by stacking in a certain mode, and the stacking combination mode comprises a single-row stacking mode and a multi-row stacking mode.

In practice, the saw cuts 3 have different designs and arrangements of different depths as required. One of the conditions is that the sawing joints are opposite, the sawing joints 3 at opposite positions on the square timber 1 are equal in depth, the sawing joints 3 are formed by one third to one half of the thickness of the square timber, a white part is reserved between the opposite sawing joints 3, and the white part 3 is positioned in the middle of the square timber. In addition, there is a case that the saw teeth of the opposite sawing grooves 3 have different depths, the design of the deep grooves and the shallow grooves is provided, and the saw slits 3 at opposite positions are deeper and shallower, so that the blank part at the junction is deviated from the middle line of the square timber, the blank parts are positioned at two sides of the middle line, and the saw slits 3 at the same side are alternately arranged in depth and shallower. In this embodiment, a plurality of square timber boards 1 are stacked in a single row to form an intermediate 2, and the sawing seams 3 on adjacent square timber boards 1 are mutually perpendicular.

Another form of saw kerf 3 is shown in fig. 5, wherein the depth of the saw kerf 3 exceeds half the thickness of the aspect 1, and the saw kerf 3 on both sides are arranged alternately. The purpose is that on the basis of realizing that the saw cutting seam 3 damages plant growth stress, tiny deformation can be absorbed, so that the overall stability is realized. However, the number of grooves and wood loss can be reduced through the thinning treatment, and the overall performance is similar.

Furthermore, on the intermediate body 2 formed by the square timber 1 arranged in a single-row superposition way, the side plates 4 are bonded on two sides of the intermediate body 2, and of course, the square timber 1 can be bonded with the side plates 4 after being bonded by an adhesive during the single-row superposition way; or the side plates 4 are independently bonded with the side plates 4, bonding is not needed between the square timber 1, and overlapping clamping of the square timber 1 is realized through the side plates 4 on two sides.

A core plate intermediate structure like a fishbone is obtained. In the core intermediate structure, as a structurally stable, progressive machining, the opposing saw cut saw tooth depths are varied to deviate the interface from the intermediate line of the intermediate. The junction is deviated from the central line, and the sawing seam depths are regularly arranged to form two rows of junctions which are alternately arranged, so that the structure is more stable and reliable. In practice, the depth of the saw cuts 3 is designed to be the same two by two, so that the front ends of the saw cuts 3 extend forward or retract backward relative to the center line, and the junctions of the offset center lines are arranged two by two. As another possible structural design, saw slits 3 formed on two surfaces of the intermediate body are arranged alternately. The purpose of the alternate arrangement of adjacent saw cuts 3 is to make the distribution more uniform, the stress more spread, and the absorption capacity of small deformation of stability is increased.

At least one side edge of a plurality of square timber side edges which are arranged in a multi-column superposition way is adhered with a side plate 4. The side plates can be arranged on one surface, two opposite surfaces or three surfaces or four surfaces.

The multi-row laminated intermediate body 2 is mainly applied as shown in fig. 4, and the intermediate body 2 needs to be broken in equal thickness to form an elastic basic component needed by the core plate.
