Description

A kind of steel plastic-wood composite section

Technical field

The utility model relates to a kind of steel plastic-wood composite section, relates to composite material.

Background technology

In indoor engineering construction, need to use skeleton structure, conventional steel pipe has metal feel, and the temperature of material is greatly affected by environment, and can feel cool or overheated during winter or summer human contact, comfort level is lower; Timber is as skeleton structure good decorating effect, but the intensity of timber is lower, and water proofing property is poor, and easy strain cracking, not easy care.Both are combined and the easy generation gap, composition surface at both, cause connection insecure.

In addition, in long use procedure, easily there is cracking or peeling phenomenon in traditional composite material.

Utility model content

Technical problem to be solved in the utility model is to provide that a kind of intensity is high, good decorative property and the steel plastic-wood composite section of crack resistence.

For solving the problem, technical solution adopted in the utility model is:

The utility model it comprise steel pipe and be coated on the outer field interior compound timber layer of steel pipe, outside interior compound timber layer, be coated with copper mesh layers, in the outside of copper mesh layers and the mesh of copper mesh layers, have outer compound timber layer, be coated with coating layer outside compound timber layer outside;

The brass wire diameter of copper mesh layers is 0.03mm-0.5mm, and the thickness of coating layer is 0.05mm-0.1mm, the wall thickness 0.5mm-5mm of steel pipe, and the wall thickness of outer compound timber layer is 1.5-2.5 times of the wall thickness of steel pipe, and the wall thickness of interior compound timber layer is 1.5-2.5 times of the wall thickness of steel pipe,

Outer compound timber layer and interior compound timber layer are vinyl resin synthetic wood.

As further improvement of the utility model, be circumferentially evenly provided with annular knurl at steel pipe skin.

As further improvement of the utility model, described annular knurl is along steel shaft to setting.

As further improvement of the utility model, the outer surface wire drawing vertically of steel pipe is arranged.

The beneficial effect adopting technique scheme to produce is:

1, internal layer is the steel pipe with cavity, makes the utility model have higher-strength as during skeleton structure, not yielding;

2, outer employing vinyl resin synthetic wood, makes the utility model appearance have timber color and certain lines, by force ornamental; Have texture and the feel of timber, surface temperature is affected by environment little, and during human contact, comfort level is high; Comprise resin in the material of synthesis wood, the utility model is had not water funk, do not ftracture, the advantage that anti-corrosion capability is strong;

3, adopt synthesis wood and steel pipe compound, synthesize under wooden material characteristic can realize the state of melting at it and be poured onto steel pipe outside, and then cooling and shaping, processing technology is simple, connects tight;

4, stiffener one end and fastener for connection, and be deep in synthesis timber layer, make synthesis timber layer not easily rotate relative to steel pipe and move;

5, when temperature reduces, shrink due to synthesis timber layer and be greater than steel pipe, connection can be caused after producing gap between the two to loosen, and square fixed head can inwardly hospitalize synthesis timber layer, prevents mobile.

Adopt the utility model as building and decoration bar section, have advantage practical and attractive in appearance simultaneously concurrently, be particularly useful for the indoor engineerings such as building guardrail, fence, sash, furniture, durable in use, there are wide market prospects.

Accompanying drawing explanation

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

Wherein: 1, outer compound timber layer; 2, copper mesh layers; 3, interior compound timber layer; 4, steel pipe; 5, coating layer; , outer compound timber layer 1, copper mesh layers 2, interior compound timber layer 3, steel pipe 4, coating layer 5.

Detailed description of the invention

As shown in Figure 1, the utility model comprises steel pipe 4 and is coated on the outer field interior compound timber layer 3 of steel pipe 4, outside interior compound timber layer 3, be coated with copper mesh layers 2, in the mesh of the outside of copper mesh layers 2 and copper mesh layers 2, have outer compound timber layer 1, be coated with coating layer 5 outside compound timber layer 1 outside; By arranging copper mesh layers 2, realizing in compound timber layer, add crack resistence " tension muscles and bones ", prevent the cracking of compound timber layer or peel off, adding its intensity and inner interaction force.Coating layer 5 increases the intensity of compound timber layer, prevents cracking further, is scratched or collides with.Outer compound timber layer 1 is referred to as compound timber layer with interior compound timber layer 3.

The brass wire diameter of copper mesh layers 2 is 0.03mm-0.5mm, preferably 0.03,0.05 or 0.1, the thickness of coating layer 5 is 0.05mm-0.1mm, preferably 0.08 or 0.1, the wall thickness 0.5mm-5mm of steel pipe 4, the wall thickness of outer compound timber layer 1 is 1.5-2.5 times of the wall thickness of steel pipe 4, and the wall thickness of interior compound timber layer 3 is 1.5-2.5 times of the wall thickness of steel pipe 4.The length being shorter in length than steel pipe 4 of copper mesh layers 2, the length being shorter in length than compound timber layer of copper mesh layers 2.

Outer compound timber layer 1 is vinyl resin synthetic wood with interior compound timber layer 3, structure is identical, be specially pouring after the external overall heating of steel pipe 4 to mix and the synthesis wood raw material melted, in its molten condition, copper mesh layers is coated in compound timber layer, or when centrifugal pouring, copper mesh layers is set within it.

Further, be circumferentially evenly provided with annular knurl, enlarge active surface at steel pipe 4 skin, the embedded cooperation of compound timber layer 3 in realizing, increase adhesive strength.

Further, annular knurl is axially arranged along steel pipe 4, is easy to shaping, gains in strength.

Further, the outer surface wire drawing vertically of steel pipe 4 is arranged, and improves the intensity of matrix steel tube 4.

As the distortion of this programme, steel pipe 4 can be the common structures such as pipe, square tube or special pipe.Adopt the utility model as building and decoration bar section, have advantage practical and attractive in appearance simultaneously concurrently, be particularly useful for the indoor engineerings such as building guardrail, fence, sash, furniture, durable in use, there are wide market prospects.

Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in previous embodiment, or carries out equivalent replacement to wherein portion of techniques feature; It is apparent for carrying out combination as those skilled in the art to multiple technical scheme of the present utility model.And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of the utility model embodiment technical scheme.
