Green and environment-friendly aluminum wood composite building material for preventing deformation and cracking

Abstract

The invention relates to a green and environment-friendly aluminum wood composite building material for preventing deformation and cracking, including an aluminum plate workpiece and a log wood sheetor a workpiece; one surface of the log wood sheet or the workpiece is provided with at least one buckle groove; one surface of the aluminum plate workpiece is provided with at least one buckle strip;the aluminum plate workpiece is buckled with the buckle groove through the buckle strip and combines to be a whole with the log wood sheet or the workpiece by locking the workpiece from the other surface of the aluminum plate to the log wood sheet or the workpiece; a telescopic expansion gap is formed between the bottom of the buckle groove and the top of the buckle strip. The assembly structure of the composite building material is very simple, easy to assemble and do not use the specialized equipment for assembly; the composite building material is easy to manufacture, low-cost, and is not deformed and cracked; the composite building material is very suitable for the production and application of thin aluminum wood composite building material and the aluminum wood composite door and window frame.

Description

technical field [0001] The invention relates to the field of furniture boards, building boards or building decoration boards, in particular to an aluminum-wood composite building material. Background technique [0002] At present, in the process of house decoration, most of the original wood boards are used. Most of the pure original wood boards are prone to cracking and deformation due to climate changes. In addition to making new original wood boards, it will cause environmental damage; the wooden floor made of original wood boards is vulnerable to climate change, cracking, deformation, poor durability, and poor quality reliability. Before the installation of the floor, it is necessary to Grinding and smoothing is a time-consuming and labor-intensive process. When it is necessary to lay wires, water pipes, and floor heating under the ground, it is necessary to slot on the bottom surface. The slotting process is also time-consuming and labor-intensive, and may damage the st...

AI Technical Summary

Problems solved by technology

However, the aluminum-wood composite door and window frame obtained in this way has been found to have several deficiencies through repeated on-the-spot observation and research by the applicant: one, the material of the aluminum-wood composite door and window frame in this way is first Aluminum and wood composites are assembled together, and then cut and applied, which will result in waste of aluminum and solid wood, which is a large waste, which is not conducive to saving raw materials

The second is that the combination of aluminum and solid wood needs special mechanical equipment to position and fix the aluminum and push the solid wood square strips into the aluminum to form the aluminum-wood composite material before it can be applied. The production equipment is invested higher cost

The third is that the solid wood strips are embedded in the aluminum material, and there is no room for expansion and contraction. The solid wood strips are prone to cracking and deformation, and after cracking or deformation, the gaps at the joint corners will increase, or become warped. It will affect the appearance and grade of aluminum-wood composite doors and windows

Therefore, the existing aluminum-wood composite doors and windows still have relatively large technical defects, and cannot achieve a more perfect technical effect.
