Embodiment Construction
[0017] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0018] figure 1 It is a hexagonal prism (1) with a small section, and three adjacent surfaces (3) can be glued, figure 2 It is an isosceles trapezoid (2), and three adjacent surfaces (4) can also be coated with glue. According to the position of the glulam structural unit body in the billet model, three sides, two sides or one side can be selected for coating glue.
[0019] image 3 There are three types of billet models for large-section hexagonal prisms, namely Model I (13+6), Model II (43+12) and Model III (91+18). Model I (13+6) contains 13 small-section hexagonal prisms (1) and 6 isosceles trapezoids (2), of which there are 6 small-section hexagonal prisms (1) and 6 large-section hexagonal prisms On the edge, and each side of the regular hexagon in the cross-section of the large-section hexagonal prism contains an isosceles trapezoidal lower base. ...

The invention provides a large-section hexagonal prism laminated wood manufacturing method which aims to solve the technical problem that in the process of manufacturing large-section hexagonal prism laminated wood through small-diameter-class logs, precision of gluing, assembling, pressing binding and the like is not high, and accordingly quality of large-section hexagonal prisms is difficult to guarantee. The new technology includes the steps of diameter class grading of the small-diameter-class logs, drying, laminated wood structure unit processing, length fixing, gluing, assembling and splicing through glue. The method is characterized in that a laminated wood structure unit is processed into small-section hexagonal prisms (1) and isosceles trapezoids (2), the cross section of each small-section hexagonal prism (1) is of a regular hexagon shape, three sides (3 and 4) of each small-section hexagonal prism (1) and each isosceles trapezoid (2) are glued in a roller mode, assembling is achieved through a hexagonal prism model, the cross section of each large-section hexagonal prism is of a regular hexagon shape, and pressure is applied in three directions for binding the large-section hexagonal prism laminated wood. The method can effectively simplify the manufacturing technology of the large-section hexagonal prisms and improve the outturn percentage of the logs, production efficiency and product quality.
Description
technical field [0001] The invention relates to the field of wood structure building composite materials, in particular to a method for manufacturing a large-section hexagonal prism laminated material. Background technique [0002] In recent years, with the rapid development of wooden structures, wooden houses, wooden bridges, and landscape wooden buildings have attracted more and more attention from consumers and researchers. With the increasing demand for wooden beams and wooden columns in the wooden structure construction market, the supply of large-diameter logs is in short supply. In order to solve the problem of increasingly scarce large-diameter logs, people began to use small-diameter or low-grade timber to prepare Glulam for large-scale and large-section structures. Yet how to adopt small-diameter class and low-grade timber, as artificial forest Chinese fir etc., the wooden beam that prepares structure usefulness, wooden column has become the main topic of current ...
