Description

High-strength marine plywood

Technical Field

The invention relates to the technical field of high-strength marine plywood, in particular to high-strength marine plywood.

Background

The plywood is one of common furniture materials, is one of three large plates of an artificial plate, and can also be used as a material for airplanes, ships, trains, automobiles, buildings, packing boxes and the like. A group of veneers are typically assembled and glued perpendicular to each other in the direction of the adjacent layers of wood grain, and the skins and inner sheets are typically symmetrically disposed on either side of the center layer or core. The glued veneer is pressed into the wood grain board blank by the criss-cross matching of the glued veneer according to the wood grain direction under the condition of heating or not heating. The number of layers is generally odd, and a few are even. The difference of physical and mechanical properties in the longitudinal and transverse directions is small. The types of plywood commonly used are plywood, plywood and the like. The plywood can improve the utilization rate of the wood and is a main way for saving the wood.

The ship body is provided with most of floors made of plywood, and the common plywood can expand after meeting water, so that the plywood becomes brittle after being expanded for a long time and can be broken when being trodden.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a marine plywood of high strength, including plywood body 1, be equipped with the device that expands slowly in plywood body 1, expand the device including expansion plate 2 slowly, expansion plate 2's higher authority fixedly connected with plywood body 1, expansion plate 2's internal surface has seted up inside groove 21, two expansion plates 22 of fixedly connected with below inside groove 21, an arc 23 has all been seted up below every expansion plate 22, water enters into expansion plate 2, expansion plate 22 absorbs moisture, because arc 23 has been seted up below expansion plate 22, arc 23 is the inner groovy, consequently, expansion plate 22 absorbs moisture and can expand to both sides, trapezoidal expansion piece 24 absorbs moisture and begins to expand, three boom 25 of fixedly connected with below inside groove 21, the equal three trapezoidal expansion piece 24 of fixedly connected with of surface of every boom 25, be equipped with reinforcing apparatus in plywood body 1.

Draw-in groove 11 has been seted up to plywood body 1's the right side, plywood body 1's left side fixedly connected with block 12, a inclined plane groove 13 has all been seted up to the internal surface of two parts about plywood body 1, when plywood body 1 lays, inject second block plywood body 1's block 12 in first plywood body 1's draw-in groove 11, lay with this, every plywood body 1 can all keep the level always, an inclined plane groove 13 has all been seted up on two sides about expansion board 2, four bracing pieces of fixedly connected with 14 between expansion board 2 and the plywood body 1, expansion board 2's internal surface fixedly connected with baffle 26, when the moisture in expansion board 2 is too much, moisture can flow down through outlet pipe 27 below the baffle 26, outlet pipe 27's length is longer simultaneously, fixedly connected with outlet pipe 27 below the baffle 26.

Reinforcing apparatus includes four picture peg 3, five slots 31 have all been seted up to per two picture peg 3's opposite face, an L-shaped groove 32 has all been seted up to the higher authority of every picture peg 3, the bracing piece 14 texture between plywood body 1 and the expansion board 2 is harder, can maximum dynamics keep plywood body 1 and expansion board 2 expansion distance, support column 33 between plywood body 1 and the expansion board 2 can contact each other when receiving the extrusion simultaneously, support column 33 can prevent the deformation of plywood body 1 and expansion board 2, four support columns 33 of equal fixedly connected with between per two picture peg 3, the equal fixed connection of every picture peg 3 is at plywood body 1's internal surface.

Specifically, when the invention is used:

the first step is as follows: when plywood body 1 lays, inject the block 12 of the 1 block of second plywood body into the draw-in groove 11 of the 1 block of first plywood body, lay with this, every plywood body 1 can all keep the level always, when plywood body 1 runs into water, plywood body 1 can produce the inflation of absorbing water, water enters into expansion plate 2, expansion plate 22 absorbs moisture, because arc 23 has been seted up below expansion plate 22, arc 23 is the inner groovy, consequently, expansion plate 22 absorbs moisture can expand to both sides, trapezoidal expansion block 24 absorbs moisture and begins the inflation, because be big above trapezoidal expansion block 24, it is little below, consequently, trapezoidal expansion block 24 can use cluster pole 25 to expand to both sides as the center, it is full of with expansion plate 2 inner wall inflation through expansion plate 22 and trapezoidal expansion block 24 this moment, thereby be favorable to improving plywood body 1's toughness.

The second step is that: the support rod 14 between the plywood body 1 and the expansion plate 2 is hard, the expansion distance between the plywood body 1 and the expansion plate 2 can be kept by the maximum force, meanwhile, the support columns 33 between the plywood body 1 and the expansion plate 2 can be in mutual contact when being extruded, the support columns 33 can prevent the deformation of the plywood body 1 and the expansion plate 2, when the moisture in the expansion plate 2 is excessive, the moisture can flow downwards through the water outlet pipe 27 below the partition plate 26, meanwhile, the length of the water outlet pipe 27 is longer, the water can be prevented from being poured into the expansion plate 2 under the water flush, most of floors in a ship body are plywood, the common plywood can expand after meeting the water, the plywood can become brittle after being expanded for a long time, the expansion can be broken when being trampled, the expansion device is full of the expansion plate 2 when meeting the water through the expansion plate 22 and the trapezoidal expansion block 24, so that the toughness of the plywood body 1 when being trampled is improved, the plywood body 1 is prevented from being broken.
