Door core structure and manufacturing method

Abstract

The invention relates to a door core structure and a manufacturing method. The door core structure comprises a core board body; the core board body is arranged in a grid shape; jointed board door fasteners are arranged on the periphery of the outer side of the core board body; ventilation grooves are formed in the jointed board door fasteners; push surface medium density fiberboards are arranged on the surfaces of the core board body and the jointed board door fasteners; and solid wood sealing edges are arranged at the edges of the jointed board door fasteners and the push surface medium density fiberboards. The problems of wood deformation, cracking and wet expansion are solved in the two directions of the structural form and the treatment process. An adopted drying method is high-temperature and low-humidity drying, and elimination of the internal stress of wood is accelerated. Meanwhile, battens are arranged in a latticed mode, structural sections on the upper side and the lower side are arranged according to the height of a door body, and stress is uniform; and a middle bearing section adopts transverse battens formed by combining a plurality of batten materials, and the transverse battens are continuously and uniformly distributed in multiple sections, so that the internal stress among the battens is ensured to be fully disordered, and material distortion is effectively controlled.

Description

technical field [0001] The invention relates to a door core, in particular to a door core structure and a manufacturing method, and belongs to the technical field of wooden door production. Background technique [0002] Doors are divided into outdoor and indoor doors, and indoor doors are generally used in bedrooms and living rooms. In the current wooden door manufacturing, in order to save wood resources, and to achieve some lightweight, fire-resistant or other functions, this is usually done. Make the wooden door core first, fill the space in the middle of the wooden door core, and finally cover the surface of the wooden door core, so that an indoor wooden door is completed. The solid wood door of this structure has a great price advantage because it uses less solid wood, and it exists widely in the actual market. However, when the wooden door core of this kind of wooden door is made, sometimes in order to reduce the quality or obtain the experience similar to that of a ...

AI Technical Summary

Problems solved by technology

In the existing wooden door structure, there is no scientific door core board arrangement process that causes the deformation of the wooden door leaf. The main reason is that the structure is unstable, and the physical shape of the board is found to change when the product is affected by the climate in different geographical locations. Due to deformation and cracking during long-term use, the touch and structural strength of solid wood doors are affected, so further improvement is needed
