Abstract
The utility model relates to an anti-deformation wooden layer laminated material, which comprises face plates positioned at the surface layers and a core plate sandwiched between the face plates, and formed by gluing the core plate with the face plates. The anti-deformation wooden layer laminated material is characterized in that the surfaces of the face plates facing inwards and double surfaces of the core plate are provided with a plurality of uniformly distributed stress releasing slots by cutting, the depths of the stress releasing slots are not more than half of the thicknesses of the plates, and distance between adjacent stress releasing slots is not more than 500mm. The anti-deformation wooden layer laminated material has the advantages that, the stress releasing slot notches are cut, so that textures of veneers made of the wooden layer laminated material are not influenced, the stress effect can be greatly reduced and homogenized, stress concentration of the wooden layer laminated material can be effectively released, warping and deformation are further reduced, and the stability is enhanced; the anti-deformation wooden layer laminated material overcomes the limitation of stress concentration of traditional wooden layer laminated material, thus being applicable to increasing production specification of thickness of the laminated material.
Description
Technical field:
The utility model relates to a kind of anti-deformation wood laminated timber, especially at panel and central layer surface, offers stress relief grooves.
Background technology:
As everyone knows, wooden laminated timber is concentrated under effect at stress, can produce the metabolies such as warpage, distortion, cracking.The destruction cause for avoiding wooden laminated timber stress to concentrate, traditional laminated timber production technology way is that inner panel is carried out to layout with transverse and longitudinal chi structure, this technique has effectively been alleviated the stress that the layout of the single forward structure of laminated timber causes and has been concentrated.But transverse and longitudinal intersection layout structural manufacturing process relieve stresses effect is very limited, does not reach some engineering material standards far away, also can not meet the laminated timber market demand that more large scale specification is produced.This is just badly in need of a kind ofly further solving the concentrated structure-improved of wooden laminated timber stress, and then effectively prevents metaboly.
Summary of the invention:
The purpose of this utility model is the anti-deformation wood laminated timber that a kind of panel inner surface of design and central layer double open are provided with stress relief grooves.
Technical solutions of the utility model are achieved in that a kind of anti-deformation wood laminated timber, include the panel in top layer and be folded in the central layer within panel, and formed by central layer and panel gummed, it is characterized in that panel inwardly a side surface and central layer two-sided, cut into several equally distributed stress relief grooves; Described Stress Release groove deep is to be not more than 1/2nd of thickness of slab, and adjacent Stress Release separation is not more than 500mm.
Stress relief grooves mutual dislocation on described central layer is two-sided; Described panel also becomes to be dislocatedly distributed with the stress relief grooves of central layer cemented surface.
Described stress relief grooves becomes broached-tooth design.
The utility model beneficial effect is, takes cutting Stress Release notch, do not affect wooden laminated timber decoration panel beautiful texture, it can reduce greatly, average stress effect, can effectively discharge wooden laminated timber stress and concentrate, further reduce warpage and metaboly, and then improving stability; The utility model overcomes conventional wooden laminated timber stress and concentrates limitation, is applicable to strengthening laminated timber thickness production specification.
Accompanying drawing explanation:
Below in conjunction with concrete legend, the utility model is described further:
Fig. 1 anti-deformation wood laminated timber perspective exploded view
Fig. 2 anti-deformation wood laminated timber schematic perspective view
Wherein
1-panel, 2-central layer, 3-stress relief grooves
The specific embodiment:
See figures.1.and.2, anti-deformation wood laminated timber, includes panel 1 and central layer 2, and panel 1 is folded in central layer 2 outsides, and gummed forms; Wherein panel 1 inwardly a side surface and central layer 2 two-sided, cut into several equally distributed stress relief grooves 3; Furthermore, 3 one-tenth broached-tooth designs of stress relief grooves, groove depth is to be not more than 1/2nd of thickness of slab, adjacent stress relief grooves 3 spacing are not more than 500mm.
Moreover, stress relief grooves 3 mutual dislocation on central layer 2 is two-sided; Panel 1 also becomes to be dislocatedly distributed with the stress relief grooves 3 of central layer 2 cemented surfaces, can avoid because stress relief grooves exists, and reduce the intensity of laminated timber.
Claims (3)
