Hollow glued-laminated timber round stake and manufacturing method

Abstract

The invention discloses a hollow glued-laminated timber round stake and a manufacturing method, which belong to the field of timber manufacturing. The round stake is of a hollow structure, the section of the round stake is annular, and the round stake comprises a member unit and an adhesive layer or comprises the member unit, the adhesive layer and a connection unit. The member unit is fixedly connected with the connection unit through the adhesive layer. The manufacturing method comprises adopting small specification solid wood converted timbers to manufacture glued-laminated timbers and assembling, splicing and forming the glued-laminated timbers. The round stake is stable and reliable in product structure performance and free of limit on product size. The wall thickness of the round stake can be adjusted according to using conditions and requirements for structure design. Units which form the products are combined through finger joints, mortise and tenon joints and high strength tree timber serving as wedge blocks to be embedded, so that integral rigidity is improved. The round stake can be used as wood columns for wood structure buildings or applied to gardens, the wood columns are of hollow structures, water pipes, lines, cables and the like can be arranged in the insides in hiding mode, and attractiveness of buildings is enhanced. The hollow glued-laminated timber round stake can replace traditional log stakes.

Description

technical field [0001] The invention discloses a novel building material and a preparation method thereof, in particular to a hollow-core laminated plywood glued wood round column and a preparation method thereof. Background technique [0002] The wooden column that exists in the market at present, its preparation method and characteristics are as follows: [0003] 1. Logs of the required size are directly harvested, processed into cylinders through surface peeling or planing, and used directly: [0004] For large-scale, straight-grained round wooden columns, especially when high-quality wood is required, this method of directly utilizing logs has become more and more difficult. In addition, for logs with large length and diameter, due to the large horizontal size of the wood, drying and anti-corrosion treatment of the material is difficult, and the raw material without pretreatment is used directly, and the product will generally have severe cracking, deformation, and warp...

AI Technical Summary

Problems solved by technology

[0009] In view of the problems in the above-mentioned prior art of the poor quality of imitation log columns, the direct use of log columns is easy to crack and deform, large-scale logs are not easy to obtain, the manufacturing process of cylindrical laminated veneer timber columns is complicated, and the appearance visibility is poor, etc., The invention provides a hollow-core plywood glued wood round column and a preparation method thereof. By using small-sized solid wood sawn timber to manufacture glued wood, the glued wood is combined and spliced ​​to form a method, which overcomes the above-mentioned problems and effectively solves the problems of arbitrary specifications. Dimensional round wooden columns are not easy to obtain, log wooden columns are easy to crack and deform during use, defects such as decay and knots in log wooden columns are not easy to remove, solid core wooden columns have poor decoration and decoration effects, and the manufacturing process of cylindrical LVL wooden columns Complicated, poor appearance visibility and other issues
