Wide 20 ~ 50 mm in the bottom surface of the isosceles trapezoid groove that the end face of described bottom plate is opened, groove depth is 2/5 ~ 2/3 of a bottom plate thickness, the inclined angle alpha of trapezoidal pair of waist of this groove is 8 ~ 10 degree.
The center line of outermost two isosceles trapezoid grooves is from spacing 120 ~ 150 mm of this bottom plate near-end, and every interval 200 ~ 300 mm have an isosceles trapezoid groove and are embedded in the batten in it between these two isosceles trapezoid grooves.
The beneficial effect of the utility model is that the vertical and horizontal intensity of composite plate is high, rationally utilizes high-quality timber and fast growing wood, and the adding of trapezoidal horizontal cutting has increased horizontal splicing intensity, mechanical strength and non-deformability, and the stability of slab integral improves.
Description of drawings
Fig. 1 is this stable type high strength solid wood composite board structural representation.
Fig. 2,3,4 is respectively the bottom plate of entire plate, side assembly, the structural representation that finger wood side jigsaw is made the bottom plate.
The specific embodiment
The utility model below will combine embodiment and further detail with reference to accompanying drawing:
Referring to accompanying drawing 1; Wherein surface layer 1 plate is the thin plate of assortments such as high-quality hardwood or clean mark timber such as oak, beech, maple wood, teak, masson pine; Process the small breadth rectangular slab, adopt entire plate to make the surface layer plate, the little plank of processing than the large format floor of available polylith is combined into.Sandwich layer 2 is a soft wood single-plate among poplar, the Liu An etc., and the plate of bottom 3 is entire plate or side jigsaw or finger wood side jigsaw such as fast growing wood such as China fir, poplar.The isosceles trapezoid groove is arranged on the bottom plate, and inserting embedding in the groove and gluing together has batten 4.
Concrete making can be operated as follows:
(1) confirming and preliminary treatment of layers of material:
Surface material: surface layer 1 material is used the oak thin plate, and this lamella thickness is that 2mm, width are that 90 mm, length are 930mm, and moisture content is 6 ~ 8%;
The material of sandwich layer 2: with the board using poplar board of thickness 1.0 mm;
The material of bottom 3: the thickness that three textures are all vertically arranged is that 16mm, width are that 30 mm, length are that to be combined into overall width be that the plate of 90 mm is made base plate for the China fir side of 930mm.Bottom layer length and width are consistent with the length and the width of surface layer; On the end face of bottom plate longitudinally, have at least two horizontal isosceles trapezoid grooves parallel to each other, the center line of outermost two dovetail grooves is from spacing 120 ~ 150 mm of this bottom plate near-end, and every interval 200 ~ 300 mm increase an isosceles trapezoid groove again between these two dovetail grooves; The degree of depth of this groove is 2/5 ~ 2/3 of a bottom plate thickness; Wide 20 ~ 50 mm of the bottom land of every dovetail groove, the inclined angle alpha of the two waists of dovetail groove is 8 ~ 10 degree, after being coated with normal temperature cured type glue on this groove bottom and the two central plane; The batten that inserted-shape and size are all identical with this groove solidifies and to compose sanding surface after the one;
(2) select glue and applying glue: select the isocyanate glue of urea-formaldehyde resin adhesive or normal temperature cured type, to the double spread up and down of sandwich layer veneer, single spreading amount 120 ~ 160 g/m of urea-formaldehyde resin adhesive
