Structural slab and slab core and machining method of slab core

Abstract

The invention discloses a slab core of a structural slab. The slab core is provided with multiple structure units, the structure units are sequentially stacked and attached in an adhesive mode in the length direction of the structural slab, each structure unit comprises a substrates and a shearing force body inclined relative to the substrate, the substrates are stacked in the length direction of the structural slab to form a frame shearing force structure, each substrate is provided with a continuous transverse pressure-bearing body and a vertical pressure-bearing body extending in the thickness direction of the structural slab, each shearing force body at least comprises two layers of shearing force layers and a plurality of shearing force piece strips arranged at intervals, and one shearing force piece strip and the shearing force piece strips corresponding to the adjacent shearing force layers in position are crossed and stacked. By means of the arrangement, the frame shearing force structure can be formed, the strength of the structural slab is effectively improved, the bearing capacity of the structural slab is improved, consumption of wood resources is reduced, energy is saved and environment protection is achieved. On the basis of the slab core, the invention further provides the structural slab with the slab core and a machining method of the slab core of the structural slab.

Description

technical field [0001] The invention relates to the field of man-made board manufacture, in particular to a structural board, a board core, and a processing method for the board core. Background technique [0002] At present, due to the shortage of wood resources, the price of solid wood is expensive. At the same time, the wood itself has strong internal stress, which cannot meet the performance requirements of wood in modern architectural furniture. Also, the use of solid wood does not meet the social requirements of protecting tree resources. Therefore, wood-based panels emerge as the times require, and further development of the performance of wood-based panels is one of the important research directions for those skilled in the art. [0003] In the prior art, wood-based panels are mainly oriented structural boards, also known as oriented strand boards, which are formed by arranging the shavings in a certain direction and pressing them horizontally. In this way, the man...

Problems solved by technology

In this way, the manufactured product has large deflection and deformation, poor resistance to internal stress deformation, and small application range.

[0004] Moreover, wood-based panels are made by pressing solid wood or wood slices, and the weight of the product is relatively large, and the amount of consumables is also relatively large; moreover, when pressing the products, a large amount of glue needs to be consumed for bonding, which not only wastes resources, but also As a result, the formaldehyde content of the product is high, which does not meet the production requirements of environmental protection

[0005] In the current production of structural panels, the panel core needs to be formed by pressing with a specific mold. Due to the limitation of the specifications of the mold, the types of thickness specifications of the panels are relatively limited, which restricts the post-processing and utilization of the panels.

At the same time, the core of the current structural board is usually made of one material, and the transmission direction of the sound wave vibration is the same, which cannot effectively weaken the sound wave transmission, so the sound insulation effect of the current structural board is poor
