Embodiment 1

[0021] The manufacturing method of fir flooring, its operation steps are as follows:

[0022] a. Saw board: saw the fir with a tail diameter of 80 mm into a board with a thickness of 22 mm;

[0023] b. Health preservation: Put the boards in a rain-proof and ventilated environment and dry them for 10 days. Use multiple 22mm×22mm wooden strips between each layer of boards for upper and lower intervals;

[0024] c. Drying: Put the finished plates in the drying cellar and dry them to the moisture content range of 8% to 13%, and then exit the cellar;

[0025] d. Shaping: stack the boards out of the kiln to dry for 6 days in a rain-proof and ventilated environment, and use multiple 22mm×22mm wooden strips between each layer of boards for upper and lower intervals;

[0026] e. Saw blade: sawing the finished plate into a square strip with a square cross-section, the side length of the square: 22 mm × 22 mm;

[0027] f. Selection: After cutting off the decayed section of the square strips, the sq...

Embodiment 2

[0033] The manufacturing method of fir flooring, its operation steps are as follows:

[0034] a. Saw board: Saw a fir with a tail diameter of 120 mm into a board with a thickness of 24 mm;

[0035] b. Health preservation: Put the boards in a rain-shielded and ventilated environment and dry them for 15 days. Use multiple 24 mm x 24 mm wooden strips between each layer of boards for upper and lower intervals;

[0036] c. Drying: Put the finished plates in the drying cellar and dry them to the moisture content range of 8% to 13%, and then exit the cellar;

[0037] d. Shaping: Stack the boards out of the kiln to dry for 8 days in a rain-shielded and ventilated environment, and use multiple 24mm×24mm wooden strips between each layer of boards for upper and lower intervals;

[0038] e. Saw blade: sawing the finished sheet into a square strip with a square cross section, the side length of the square is: 24 mm × 24 mm;

[0039] f. Selection: Use the strategy of having at least one side surface i...

Abstract

The invention discloses a fabrication method of a cedar floor, which comprises the following steps that a cedar with the tail diameter of at least 80mm is sawed into plates with certain thicknesses; the plates are sawed into square strips with square cross sections after stack drying is conducted on the plates; the square strips are cut into main square strips and auxiliary square strips; one intact and smooth side surface of each auxiliary square strip is selected as a plate surface; the end heads of at least two auxiliary square strips are butted and bonded into splicing square strips; one intact and smooth side surface of each main square strip is selected as a plate surface; the main square strips and the splicing square strips are arranged alternately side by side; the surfaces of the main square strips and the surfaces of the splicing square strips face towards the same direction; the side surfaces of the adjacent main square strips and the splicing square strips are pressed into floor blanks after bonded by an adhesive; the floor blanks are processed and painted; and the fabrication of the cedar floor is accomplished. Compared with the prior art, a superior product rate of the fabricated cedar floor is above 95%, and a comprehensive utilization ratio of wood and a high quality rate of a product are increased greatly.

Description

Technical field [0001] The invention relates to the technical field of wood processing, in particular to a manufacturing method for fir flooring. Background technique [0002] The cedar tree grows fast and is one of the most important special timber species in southern my country, especially Guangxi. Fir has straight texture and fine wood. It is widely used in construction, flooring, furniture, etc. The traditional method of making fir flooring is usually to select fir with a diameter of 140 mm or more, and process the fir into: 450 mm to 900 mm in length, 90 mm to 120 mm in width, and thickness of Cedar flooring of 18mm-20mm. As the Chinese fir is characterized by many knots and cracks, the number of knots and cracks in the cedar floor produced by this method is more than two per 500 mm in length, and the diameter of the knots and cracks is also greater than 5 mm. , The high-quality product rate is less than 30%, therefore, most fir flooring can only become commodities with l...
