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
The present invention relates to the larchen integrated timber of path.
Background technology
China's artificial forest larch accumulation occupies first place in the world at present.The larch growth cycle is short, the footpath level is little, defective many and the difficulty dry, and its utilization rate is low, and range of application is restricted; In recent years, ripe gradually along with domestic larch undersized log dry technology is for the further utilization of larch undersized log provides the foundation; But the larchen utilization of path also only limits to directly be used as construction purlin or mine timber at present, and there is the extremely low problem of scientific and technological content and added value of product in the larchen utilization of path, is difficult to satisfy the constantly demand of development of China architecture and decoration market.
Summary of the invention
The objective of the invention is can only provide a kind of small-diameter profiled unit material glued structures beam, post directly as the problem of construction purlin or mine timber for solving existing path larch.The present invention makes the larch small dimension wood be processed into structure with beam (post) material through integrated gummed, and its saw lumber volume recovery improves than conventional method, can be used as ornament materials such as the load-bearing material such as structural beams, post of building structure and door and window, balustrade.Properties of product reach the characteristics of structure integrated timber standard-required.The present invention comprises the 1/1st unit material 1, the 1/2nd unit material 2, the 1/3rd unit material 3 and the 1/4th unit material 4, it is the 1/1st integrated timber 11 that the 1/1st unit material 1 and the 1/2nd unit material 2 are adhesively fixed by resin glue 5, it is the 1/2nd integrated timber 12 that the 1/3rd unit material 3 and the 1/4th unit material 4 are adhesively fixed by resin glue 5, the 1/1st integrated timber 11 and the 1/2nd integrated timber 12 are adhesively fixed by resin glue 5 and form column 6, and the cross section of column 6 is a rectangle 7.Preparation method of the present invention is: utilize existing saw lumber equipment, by medulla sawing method (promptly the horizontal saw of undersized log, a perpendicular saw being the cutting of " ten " font), carry out the blank processing of path larch log 1/4th unit materials; / 4th unit material blanks after drying carry out five special-shaped Milling Process; Again 1/4th unit materials after two Milling Process are carried out the integrated gummed of 1/2nd integrated wooden frames (post), carry out the integrated gummed of whole integrated wooden frame (post) at last again by two 1/2nd integrated wooden frames (post), promptly obtain small-diameter profiled unit material glued structures beam (post).The invention has the beneficial effects as follows: utilized the larch undersized log fully efficiently, the larchen volume recovery of path, utilization rate have been improved, its saw lumber volume recovery improves more than 8% than prior art, enlarged the larchen range of application of path, the larch undersized log is made structure with beam or post material, can be used as ornament materials such as the load-bearing material such as structural beams, post of building structure and door and window, balustrade.Its properties of product have reached the standard-required of structure integrated timber, have improved the scientific and technological content and the added value of product of path larch material.The shear strength of the small-diameter profiled unit material glued structures of the present invention beam, post is greater than 7.2Mpa; Modulus of elasticity is greater than 10.5 * 10
3Mpa; Flexural strength is greater than 38Mpa.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention, and Fig. 2 is a path larch medulla sawing schematic diagram, and Fig. 3 is the structural representation of the specific embodiment three.
The specific embodiment
The specific embodiment one: (referring to Fig. 1, Fig. 2) present embodiment is by the 1/1st unit material 1, the 1/2nd unit material 2, the 1/3rd unit material 3 and the 1/4th unit material 4 are formed, it is the 1/1st integrated timber 11 that the 1/1st unit material 1 and the 1/2nd unit material 2 are adhesively fixed by resin glue 5, it is the 1/2nd integrated timber 12 that the 1/3rd unit material 3 and the 1/4th unit material 4 are adhesively fixed by resin glue 5, the 1/1st integrated timber 11 and the 1/2nd integrated timber 12 are adhesively fixed by resin glue 5 and form column 6, and the cross section of column 6 is a rectangle 7.The preparation method of present embodiment is: utilize existing saw lumber equipment, by medulla sawing method (promptly the horizontal saw of undersized log, a perpendicular saw being the cutting of " ten " font), carry out the blank processing of path larch log 1/4th unit materials; / 4th unit material blanks after drying carry out five special-shaped Milling Process; Again 1/4th unit materials after two Milling Process are carried out the integrated gummed of 1/2nd integrated wooden frames (post), carry out the integrated gummed of whole integrated wooden frame (post) at last again by two 1/2nd integrated wooden frames (post), promptly obtain small-diameter profiled unit material glued structures beam (post).
The specific embodiment two: the difference of (referring to Fig. 1, Fig. 2) present embodiment and the specific embodiment one is, the reel place 8 of each 1/4th unit material is arranged on the exterior angle 9 of column 6 that the cross section is a rectangle 7.Other composition is identical with the specific embodiment one with annexation.What obtain by the medulla sawing procedure is the quarter sawing material, and it is high that the non-quarter sawing material of its strength ratio is wanted, and has anisotropy by integrated wooden frame, post behind the integrated gummed again, has reduced distortion of materials, has effectively prolonged the application life of material.
The specific embodiment three: (referring to Fig. 3) present embodiment and the specific embodiment one or twos' difference is, it has increased a May 4th/unit material 10, the May 4ths/end of a unit material 10 and an end of the 1/1st unit material 1 is fixed by resin glue 5 fingers.Form 1/4th unit materials of lengthening, carry out the integrated gummed of 1/2nd integrated wooden frames (post) with 1/4th unit materials of lengthening, carry out the integrated gummed of whole integrated wooden frame (post) again by two 1/2nd integrated wooden frames (post), promptly obtain the small-diameter profiled unit material glued structures beam (post) that extends.Present embodiment can make undersized log larch range of application be able to sufficient expansion, by the finger processing method with short and small unit material spreading; Adopt the mode of the horizontal assembly of gummed the integrated wooden frame in unit (post) gummed can be integrated into longer structural beams (post) material.
The specific embodiment four: the difference of (referring to Fig. 1) present embodiment and the specific embodiment one is, is provided with axial cavity 13 at the center of column 6.Other composition is identical with the specific embodiment one with annexation.The hollow structure of column 6 is the result who removes bark on the one hand, and the source that grows that can reduce bacterium, insect on the other hand under the prerequisite that does not influence functional performance, makes it have sound insulation, heat insulation effect.
