CN203485271U - Composite bamboo section bar with glue guiding holes - Google Patents

Abstract

The utility model relates to a composite bamboo section bar with glue guiding holes. The section bar comprises a bamboo skin layer, a bamboo wood layer and a bamboo muscle layer. The bamboo skin layer is provided with glued structures deep into the bamboo wood layer, and the glued structures are the glue guiding holes. The glued structures are deep into a fiber layer of the bamboo wood layer, and adhesives are filled in the glued structures to form an adhesive layer. There are 6000 to 9000 said glue guiding holes per square meter. The depths of the glue guiding holes into the bamboo wood layer are 20% to 50% of the height of the bamboo wood layer. The cross section of each glue guiding hole is in a V shape, and the distances between the adjacent glue guiding holes are between 8 and 15 mm. Arrangement of the glue guiding holes increases the effective glued area, so that the bonding strength is significantly enhanced. After bonding, the overall bending strength is increased to 45 to 89 MPa. And during bonding, the surface of the bamboo skin layer does not deform due to pressing, and thus the surface is highly flat.

Description

A kind of have a composite bamboo section bar of leading glue eye

Technical field

The utility model relates to a kind of architectural shape, is specifically related to a kind of composite bamboo section bar of leading glue eye that has.

Background technology

The former material of bamboo comprises bamboo green layer, bamboo wood layer and bamboo spring layer, cured matter is contained on bamboo green layer surface, be difficult for bonding, glue performance is poor, therefore, and in use, in order to improve the performance of gummed, the method adopting is widely to remove the bamboo green layer of bamboo wood, then glues together this method, removed bamboo green layer, the utilization rate that has reduced raw material, utilization rate of raw materials drops to 30-40%, simultaneously, the surface strength of bamboo green layer is high, in bamboo wood, surf green intensity accounts for 30-40%, removes after bamboo green layer, also greatly reduces the intensity of bamboo wood.Separately, in prior art, provide a kind of isocyanate glue that utilizes to carry out bamboo green layer and the bonding technique of bamboo wood layer, due to isocyanate glue, not only price is high, and larger containing toxicity, during operation, requirement of shelter is also high, let it be to the greatest extent, and use amount is few, but the harm bringing to operator is apparent, and this technology also can not be complied with the demand for development of asepsis environment-protecting simultaneously.

Utility model content

The utility model has been intended to provide a kind of composite bamboo section bar of leading glue eye that has, and to solve the deficiencies in the prior art, the technical problems to be solved in the utility model is achieved through the following technical solutions.

Have a composite bamboo section bar of leading glue eye, comprise bamboo green layer, bamboo wood layer and bamboo spring layer, be provided with the glued construction that gos deep into bamboo wood layer on described bamboo green layer, described glued construction is for leading glue eye; Described glued construction gos deep into the fibrage in bamboo wood layer, and adhesive is filled to and in glued construction, forms adhesive phase; The described quantity of leading glue eye is 6000-9000/㎡, and leading the degree of depth that glue eye gos deep into bamboo wood layer is the 20%-50% of bamboo wood layer height, described in lead glue eye cross section be V font; The adjacent distance of leading glue eye is 8-15 millimeter.

Further, described adhesive is white glue with vinyl or ureaformal dehyde resin glue or resin.

The utlity model has following beneficial effect: lead the setting of glue eye, make effectively to glue together area change, thereby bonding strength is obviously improved, gummed after integral bending with height to 45～89MPa, even can be higher.

Lead the setting of glue eye, make in gummed process, surf green surface can not deform because of extruding, and therefore, surface smoothness is high.

Originally, because bamboo green layer surface is too smooth, can not provide enough large frictional force, and make surperficial object easily tilt to overturn.Bamboo board after processing gummed lines determines that through contrast test its surperficial coefficient of friction will be much larger than the soft wooden board material surface of identical function, and non-skid property is good, and surperficial object is difficult for tilting to overturn.Glue together lines distribution rule even, surface aesthetic is generous, associative perception is strong simultaneously.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Reference numeral in accompanying drawing is followed successively by: 1, bamboo green layer, 2, bamboo wood layer, 3, bamboo spring layer, 4, lead glue eye.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment, further set forth design feature of the present utility model.

As shown in Figure 1, a kind of have a composite bamboo section bar of leading glue eye, comprises bamboo green layer, bamboo wood layer and bamboo spring layer, is provided with the glued construction that gos deep into bamboo wood layer on described bamboo green layer, and described glued construction is for leading glue eye; Described glued construction gos deep into the fibrage in bamboo wood layer, and adhesive is filled to and in glued construction, forms adhesive phase; The described quantity of leading glue eye is 8000 Ge/㎡, and leading the degree of depth that glue eye gos deep into bamboo wood layer is 30% of bamboo wood layer height, described in lead glue eye cross section be V font; The adjacent distance of leading glue eye is 12 millimeters.Described adhesive is resin.

Lead the setting of glue eye, make effectively to glue together area change, thereby bonding strength is obviously improved, gummed after integral bending with height to 45～89MPa, even can be higher.Lead the setting of glue eye, make in gummed process, surf green surface can not deform because of extruding, and therefore, surface smoothness is high.

The above embodiment has only been expressed a kind of embodiment of the present utility model, but can not therefore be interpreted as the restriction to the bright scope of utility model.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement.These all belong to protection domain of the present utility model.

Claims (2)

1. there is a composite bamboo section bar of leading glue eye, comprise bamboo green layer, bamboo wood layer and bamboo spring layer, it is characterized in that: on described bamboo green layer, be provided with the glued construction that gos deep into bamboo wood layer, described glued construction is for leading glue eye; Described glued construction gos deep into the fibrage in bamboo wood layer, and adhesive is filled to and in glued construction, forms adhesive phase; The described quantity of leading glue eye is 6000-9000/㎡, and leading the degree of depth that glue eye gos deep into bamboo wood layer is the 20%-50% of bamboo wood layer height, described in lead glue eye cross section be V font; The adjacent distance of leading glue eye is 8-15 millimeter.
