The invention discloses a bamboo-wood plywood, which is formed by gluing a bamboo strip curtain layer, a wood veneer layer, a bamboo mat layer, and an impregnated paper layer. The wood veneer layer, the bamboo mat layer, and the impregnated paper layer are symmetrically arranged on both sides of the bamboo strip curtain layer in sequence. The bamboo strip curtain layer is woven from radial bamboo strips without removing bamboo green and bamboo yellow, and the bamboo mat layer is woven from chordal bamboo strips with bamboo green and bamboo yellow removed by warp and weft interweaving. The invention also discloses a preparation method of the bamboo-wood plywood. The invention has the advantages of high production efficiency, few hot pressing defects, suitable density, excellent mechanical properties, and the like.

The utility model relates to a kind of portal frame and machine tool, comprising: first crossbeam and reinforcing square tube, the cavity is formed in the first crossbeam inside, the first crossbeam extends horizontally, the reinforcing square tube extends longitudinally, the reinforcing square tube is inserted into first crossbeam longitudinally and is fixedly connected with first crossbeam.The first crossbeam of the utility model is divided into multiple segments by reinforcing square tube, the first crossbeam part of the lateral two sides of reinforcing square tube is different segment, the lateral two ends of segment are supported by support structure, and the lateral length of segment is shorter than first crossbeam, so the middle part of segment is more difficult to produce bending deformation due to external force or dead weight, the first crossbeam of multiple segments is also more difficult to produce deformation, and the movement accuracy of the drive mechanism installed on the first crossbeam is improved, and the machining accuracy of workpiece is finally improved.

The utility model provides a reinforced wooden member which comprises a shape fixing cloth, and the shape fixing cloth is wound on a round wooden member of an ancient building. The round wood component is wound and reinforced through the shape fixing cloth, the transverse strength of the component is effectively improved, the wood deformation and cracking phenomena caused by environmental changes are remarkably reduced, the original style and appearance of an ancient building are kept, and the service life of the ancient building is prolonged.

The invention discloses a titanium alloy bonding glue and a use method thereof in the field of bonding glue. The bonding glue is prepared from the following raw material components: resin I, resin II, a 105 condensation amine epoxy curing agent and jade dianhydride, wherein the mass ratio of the resin I to the resin II to the 105 condensation amine epoxy curing agent to the jade dianhydride is (90-115): (30-40): (2-4): (15-30); the using method of the titanium alloy bonding glue comprises the following steps: bonding and fixing the first wave-shaped folding plate on the lower side of the upper side plate through the bonding glue; the lower side of the first wave-shaped folding plate is adhered and fixed with a partition plate I through an adhesive; a left sealing plate and a right sealing plate are correspondingly adhered and fixed to the left sides and the right sides of the upper side plate, the first partition plate, the second partition plate and the lower side plate through adhesive respectively; and a front sealing plate and a rear sealing plate are correspondingly adhered and fixed to the front sides and the rear sides of the upper side plate, the partition plate I, the partition plate II and the lower side plate through adhesive respectively. The bonding firmness degree of the titanium alloy can be improved, and the titanium alloy structural plate obtained through bonding forming is high in strength and light in weight.

The high-stability billiard lamp comprises a lamp frame and at least one lamp panel, the lamp frame comprises a plurality of lamp holders and a plurality of connecting blocks, all the lamp holders are sequentially connected end to end, any two adjacent lamp holders are connected through one connecting block, so that all the lamp holders jointly form a polygonal structure, each lamp holder comprises a plurality of folding blocks, and the folding blocks are connected through the connecting blocks. The folding blocks are sequentially connected, the folding block at the head end is connected with or separated from the folding block at the tail end, the included angle between any two adjacent folding blocks is larger than 0 degree and smaller than 180 degrees, and the lamp panel is arranged in the lamp frame. Therefore, the lamp bracket formed by the folding blocks is of a bent structure, so that the transverse strength of the formed lamp bracket can be effectively enhanced, the transverse bending resistance and the transverse torsion resistance of the lamp bracket are effectively improved, and after the lamp brackets are fixedly mounted end to end through the connecting blocks, due to the fact that the single lamp bracket is high in deformation resistance, the lamp bracket is not prone to deformation. Therefore, all parts of the polygonal structure formed by the lamp brackets are kept on the same plane, and deformation and distortion are effectively prevented.

The invention provides a regenerated cellulose fiber with a star-shaped section and a preparation method and application thereof, and relates to the technical field of textile materials. The invention provides a regenerated cellulose fiber with a star-shaped cross section. The cross section of the regenerated cellulose fiber comprises a first main body, a second main body and a third main body which are mutually crossed and have an intersection point; and the sections of the first main body, the second main body and the third main body are rectangular. The regenerated cellulose fiber provided by the invention can improve the wearing comfort and aesthetic property of fabrics.
