specific Embodiment approach 1

[0005] Specific implementation mode one: (see figure 1 , Figure 2) This embodiment is composed of the first quarter unit material 1, the second quarter unit material 2, the third quarter unit material 3 and the fourth quarter unit material 4, the first quarter unit material 4 The first quarter unit material 1 and the second quarter unit material 2 are bonded and fixed by resin glue 5 to form the first half laminated material 11, the third quarter unit material 3 and the fourth quarter unit material. One unit material 4 is bonded and fixed by resin glue 5 to form the second half laminated material 12, and the first half laminated material 11 and the second half laminated material 12 are formed by bonding and fixing resin glue 5 The columnar body 6, the cross section of the columnar body 6 is a rectangle 7. The production method of this embodiment is as follows: using the existing lumber making equipment, through the pith sawing method (that is, cutting the small-diameter wood ...

specific Embodiment approach 2

[0006] Specific implementation mode two: (see figure 1 , FIG. 2) The difference between this embodiment and the first embodiment is that the wood core 8 of each quarter unit is arranged on the outer corner 9 of the columnar body 6 whose cross section is a rectangle 7 . Other compositions and connections are the same as in the first embodiment. Quarter-sawn lumber is obtained by sawing down the pith, and its strength is higher than that of non-diameter-sawn lumber. The integrated wooden beams and columns after re-integration and gluing have anisotropy, which reduces the deformation of the material and effectively prolongs the life of the material. service life.

specific Embodiment approach 3

[0007] Specific embodiment three: (see Fig. 3) the difference between this embodiment and specific embodiment one or two is that it increases the fifth quarter unit material 10, and one end of the fifth quarter unit material 10 is connected to One end of the first quarter element 1 is finger-jointed and fixed by resin glue 5 . Form a lengthened quarter unit material, use the lengthened quarter unit material to carry out integrated gluing of one-half integrated wooden beams (columns), and then complete the integration by two half-integrated wooden beams (columns) The integrated gluing of integrated wooden beams (columns) promptly obtains elongated small-diameter special-shaped unit timber gluing structural beams (columns). This implementation method can fully expand the application range of small-diameter larch, and the short unit materials can be lengthened by finger-joining; the unit-integrated wooden beams (columns) can be glued into a longer structure by means of gluing and...

Abstract

The invention relates to a small-diameter special-shaped unit material glued structural beam and post, which provides an integrated material of small diameter larch. The invention is purposed to solve the problem of which can only be directly used as construction purlin or pitprop. In the invention, the first quarter unit material (1) and second quarter unit material (2) are glued via resin glue (5) into first half integrated material (11); the third and forth quarter unit material (3, 4) are glued via resin glue into the second half integrated material (12); and the first and second half integrated material (11, 12) are glued via resin glue into post (6). The invention has the advantages that: its material outlet rate is improved 8% than present technique, while it can be used as structural beam, post and the ornament of door and window, etc. The invention can reach the standard of structural integrated material to improve the valve of small diameter larch material.

Description

technical field [0001] The present invention relates to laminated lumber of small-diameter larch. Background technique [0002] At present, my country's artificial forest larch stock ranks first in the world. Larch has a short growth cycle, small diameter, many defects, and is difficult to dry. Its utilization rate is low and its application range is limited. Provides a foundation; however, the use of small-diameter larch is currently limited to direct use as building purlins or pit wood. The use of small-diameter larch has problems of extremely low technological content and product added value, which is difficult to meet the continuous development of my country's construction and decoration market. demand. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing small-diameter larch can only be directly used as building purlin material or pit wood, and provide a small-diameter special-shaped unit material glued stru...
