Abstract

A hollow bamboo splint veneer comprises a surface layer and a core layer which is positioned between the surface layers. The surface layer is a bamboo splint monolayer plate or a bamboo splint double layer plate. The core layer is a hollow bamboo splint grid plate or a hollow bamboo splint grid plate with a frame. The frame is made of bamboo splints or battens. Compared with the solid board, the utility model has advantages of low density, material saving, stable shape and good performance of heat and sound insulation, and is a more outstanding building material.

Description

A kind of hollow bamboo chip veneer

Technical field

The utility model relates to a kind of hollow bamboo chip veneer, and it belongs to the artificial bamboo board field.

Background technology

At present, domestic artificial bamboo board (bamboo plywood) all is to be the solid lamination structural panel of raw material processing and fabricating with the bamboo wood, though they have the high advantage of mechanical strength, but there is the shortcoming of the many and sound insulation of density height, material usage, heat-proof quality difference, truly has necessity of improvement.

Summary of the invention

The purpose of this utility model design a kind of rational in infrastructure, shape stability good and material saving, density is low, the heat-and sound-insulating performance is good artificial bamboo board---hollow bamboo chip veneer.

The so-called a kind of hollow bamboo chip veneer of the utility model comprises the top layer and places sandwich layer between the top layer, it is characterized in that: described top layer is bamboo chip lamina or doubling plate 1, and described sandwich layer is the hollow bamboo chip waffle slab 2 of hollow bamboo chip waffle slab 2 or band edge frame 3, and described frame 3 is made with bamboo bar or batten.

On structure, the utility model is by two top layers and the three-layer type centrosymmetric structure that sandwich layer is formed.Its top layer there is no too special feature, a little being particular about---it is the bamboo chip with wide uniform thickness and the hollow bamboo chip waffle slab that constitutes sandwich layer truly has, distance is sawed out the notch partly that the degree of depth is the bamboo chip width at regular intervals, the latticed material that the framework of pegging graft in length and breadth mutually then forms.Just because of this, hollow bamboo chip veneer (especially waffle slab band edge frame) though have the outward appearance and the texture of hollow bamboo chip veneer, the solid slab identical with thickness relatively, the quality of its unit area is little, the consumption of bamboo wood and bonding adhesive is also few simultaneously, thereby cost is low; The shape stability of hollow plate might as well, can produce the sheet material of large format; In addition, the heat-and sound-insulating performance of hollowcore slab also obviously is better than solid slab, so purposes is also more extensive.

Description of drawings

Accompanying drawing 1 is the structural representation of a kind of embodiment of the utility model.

Accompanying drawing 2 is structural representations of the another kind of embodiment of the utility model.

Accompanying drawing the 3,4, the 5th, the preferred structure schematic diagram the during splicing of adjacent hollow bamboo chip plate.

Among the figure, 1 bamboo chip lamina or doubling plate, 2 hollow bamboo chip waffle slabs, 3 bamboo or wooden frames, 4 splicing bamboo inserted sheets.

Specific implementation method

Example one is referring to Fig. 1, on metal caul, place a bamboo chip lamina (or doubling plate) earlier, place the hollow bamboo chip waffle slab of gluing then thereon, on waffle slab, place a bamboo chip lamina (or doubling plate) again, after hot-press gluing, promptly form hollow bamboo chip veneer slab; The saw limit mills out tongue-and-groove at middle part, sandwich layer member edge, finish processing.The splicing structure of the adjacent sheet metal of selecting for use here has as shown in Figure 3.

Example two is referring to Fig. 2, on metal caul, place a bamboo chip lamina (or doubling plate) earlier, place the gluing frame then thereon, in frame, place the hollow bamboo chip waffle slab of gluing, on frame and waffle slab, place a bamboo chip lamina (or doubling plate) again, form slab after hot-press gluing, middle side part processes splicing structure outside frame subsequently, finish processing.The splicing structure of the adjacent sheet metal that can Gong select for use here is just like Fig. 4 or shown in Figure 5.

Claims

1, a kind of hollow bamboo chip veneer comprises the top layer and places sandwich layer between the top layer, it is characterized in that: described top layer is bamboo chip lamina or doubling plate (1), and described sandwich layer is the hollow bamboo chip waffle slab (2) of hollow bamboo chip waffle slab (2) or band edge frame (3), and described frame (3) is made with bamboo bar or batten.
