Embodiment 1

[0030] The following is an example of processing a cylinder with a diameter of 500mm and a length of 10m:

[0031] 1) Select laminates with a thickness of 42mm, a width of 130mm, and a length of 10m, coat the laminates with adhesive, bond the 7 laminates, pressurize and cure them, and put them on display to obtain glulam 1 with a size of 294*130mm. Such as figure 1 shown;

[0032] 2) Carry out planing and milling processing of integrated panels, such as figure 2 shown. Then it is divided obliquely, and one is divided into two to obtain two fan-shaped unit bodies 2 whose bottoms are arc-shaped, and the side length of the fan-shaped unit body is 250mm, such as image 3 shown;

[0033] 3) Apply glue to the two isosceles sides of the fan-shaped unit body obtained in 12 steps 2), and then combine them to make a circle to obtain the required solid cylinder 3, such as Figure 4 shown.

Abstract

The invention relates to a solid cylinder gluing method. The method comprises the following steps that the diameter and height of a solid cylinder are determined according to the requirement; the number, length and side length of fan-shaped laminated unit bodies are determined according to the diameter and height of the solid cylinder; the layer number and size of laminated boards for compositing laminated wood are selected according to the determined length, number and side length of the fan-shaped laminated unit bodies, the length of the laminated boards is the length of the laminated unit bodies, the well-selected laminated boards are coated with an adhesive for gluing, and then the glued laminated wood is obtained after pressurizing, curing and aging are conducted; and planing milling machining is conducted on the laminated wood, and then subdividing is conducted, the laminated wood is divided into two parts, two unit bodies of which the lower bottoms are each of a circular-arc-shaped isosceles triangle structure are obtained, two sides of each unit body are glued, the glued unit bodies are combined to be spliced into a circle, and the needed solid cylinder is obtained.

Description

technical field [0001] The invention relates to a method for gluing cylinders, in particular to a method for gluing solid cylinders, and belongs to the technical field of construction. Background technique [0002] Wood is a natural material with excellent texture and beautiful senses. It has the advantages of beautiful patterns, luster and color, stable size, high strength-to-weight ratio, easy processing, and easy maintenance. It has become one of the most widely used raw materials and is widely used in various industries. Favored, with the development of the national economy and the continuous improvement of people's living standards, the demand for wood is increasing. [0003] At present, my country's forest resources are dominated by medium and small-diameter timber. In addition to the deforestation of natural forest resources in the early stage and the protection in the later stage, the contradiction between supply and demand of timber is serious, especially the high-q...
