Problems solved by technology

The glulam produced at present is in the shape of a plate and cannot be directly applied to courtyards and other buildings that require columnar glulam. If it is cut into a column, it will take a lot of labor and materials. Even if it is cut into a column, the column core is It is not as light and material-saving as the hollow core, and does not affect the support capacity
[0003] After retrieval and market research, it is not found that there are data reports and physical objects related to the technology in this application to come out

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the embodiments and with reference to the accompanying drawings: the hollow wood integrated column is composed of multiple (at least 3) long wooden strips (hereinafter referred to as trapezoidal strips or similar trapezoidal strips) with trapezoidal or trapezoidal cross sections. ) is glued together, as shown in Figure 2, it is glued with trapezoidal strips, figure 1 , 3, and 4 show that the trapezoidal strips are glued together, the surface of the lower bottom 3 forms the outer wall of the column, the surface of the upper bottom 4 forms the inner wall of the column, and the two sides of the trapezoidal or similar trapezoidal strips (i.e. the waist 1 of the two trapezoids) Surface) sizing, just produced adhesive layer 5 after gluing, and this adhesive layer 5 should be tight, is the laminar structure on the microcosmic concept, for explaining the problem, on the accompanying drawing, show with wide...

Abstract

The invention discloses a hollow wood integrated column, which is characterized by the following: the basic composition unit is trapezoidal wood bar with ring-shaped cross section, which is covered by three trapezoids or similar trapezoids (2); the bottom (3) of trapezoid or similar trapezoid (2) constitutes the periphery of ring, whose roof (4) constitutes the internal surface of ring; the adhesive layer (5) is coated among waists (1) of two adjacent trapezoids or similar trapezoids. The invention can be applied in architecture industry and furniture industry, which saves the raw material and time.

Description

technical field [0001] The invention relates to a wood processing product, which is a hollow cylindrical wood-glued lumber formed by gluing and molding small-diameter wood and treetops as raw materials. Background technique [0002] Due to the destruction of forest land in the early years and the need to protect forests now, the raw materials of large-diameter timber are becoming increasingly rare. Small-diameter timber, thinning timber, treetops, and wood processing residues are made into trapezoidal glulam, and glue is applied to the two waists of the trapezoid, and then hot-pressed Square-shaped glulam has been widely used in the forestry industry. The "Journal of Fujian Forestry University" in Volume 18 of 1998 published the article "Preliminary Research on Fir Glulam" by Mr. Lu Jisheng and others, and also made a related overview. The glulam produced at present is in the shape of a plate and cannot be directly applied to courtyards and other buildings that require colum...
