Description

Composite plywood

Technical Field

The utility model relates to the technical field of plywood, in particular to composite plywood.

Background

The plywood is one of the common materials for furniture, and is a kind of artificial board, and is a three-layer or multi-layer plate material made up by using wood segments and making them be cut into single boards or sliced into thin wood and using adhesive to make them be glued together, and usually using odd number of layers of single boards and making the fibre directions of adjacent layers of single boards be mutually perpendicular and glued together, and its surface board and inner layer board are symmetrically placed on two sides of central layer or board core, and the plate product is flat in appearance, large in width-thickness ratio and large in unit volume surface area, and said appearance characteristic possesses large surface area, so that it possesses strong covering power, and can be extensively used in the fields of chemical industry, container, building, metal product and metal structure, etc

The existing plywood is usually formed by directly pasting a plurality of layers of single-layer boards together by using a binder, and the phenomenon of degumming of the single-layer boards is easy to occur when the plywood is used, so that the using effect of the whole plywood is greatly reduced, and the using effect is not good enough.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to solving the above problems and providing a composite plywood.

The utility model achieves the above purpose through the following technical scheme, a composite plywood comprises a structure main body, wherein the structure main body comprises:

the core plate, and an upper panel and a lower panel which are respectively arranged on two sides of the core plate;

the core board is bonded and connected with the upper panel and the lower panel through hot-pressing glue;

the upper surface of the upper panel is provided with an upper protective layer which is in adhesive connection with the upper panel, and the lower surface of the lower panel is provided with a lower protective layer which is in adhesive connection with the lower panel;

the upper protective layer is provided with a through hole penetrating through the core plate, the upper panel, the lower panel and the lower protective layer, and a pin column tightly connected with the through hole is arranged in the through hole.

Preferably, the edge part of the structural body is sealed by polyurethane paint.

Preferably, the latch post is made of a solid wood material.

Preferably, the upper protection layer has the same structure as the lower protection layer, the upper protection layer comprises a base plate, a fireproof layer is arranged on the base plate, and a waterproof layer is arranged on the fireproof layer.

Preferably, the base plate is a wood veneer, the fireproof layer is a glass fiber layer, and the waterproof layer is a PVC material layer.

The utility model has the beneficial effects that:

the core plate, the upper panel, the lower panel, the upper protective layer and the lower protective layer are fixed through the arrangement of the bolt columns, so that the boards fall off due to degumming, and the use of the plywood is influenced; through the setting of waterproof layer and flame retardant coating, play waterproof and fireproof's effect, improved the performance of plywood.

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.

As shown in fig. 1-3:

in this embodiment, a composite plywood includes a main structure body, the main structure body includes: the core plate 2, and an upper panel 4 and a lower panel 6 which are respectively arranged on two sides of the core plate 2; the core plate 2 is bonded with the upper panel 4 and the lower panel 6 through hot-pressing glue; the upper surface of the upper panel 4 is provided with an upper protective layer 1 which is in adhesive connection with the upper panel, and the lower surface of the lower panel 6 is provided with a lower protective layer 3 which is in adhesive connection with the lower panel; the upper protective layer 1 is provided with a through hole penetrating through the core plate 2, the upper panel 4, the lower panel 6 and the lower protective layer 3, and a bolt column 5 tightly connected with the through hole is arranged in the through hole.

Wherein the edge part of the structure main body is sealed by polyurethane paint; the latch post 5 is made of solid wood; the upper protection layer 1 and the lower protection layer 3 are identical in structure, the upper protection layer 1 comprises a base plate, a fireproof layer is arranged on the base plate, and a waterproof layer is arranged on the fireproof layer; the base plate is a wood veneer, the fireproof layer is a glass fiber layer, and the waterproof layer is a PVC material layer.

According to the composite plywood disclosed by the utility model, the core board, the upper panel, the lower panel, the upper protective layer and the lower protective layer are fixed through the arrangement of the bolt columns, so that the board falls off due to degumming, and the use of the plywood is influenced; through the setting of waterproof layer and flame retardant coating, play waterproof and fireproof's effect, improved the performance of plywood.
