Abstract
The invention relates to a steel-plastic composite H-beam and a production method thereof. The H-beam comprises two mutually parallel transverse plates, and is characterized in that two mutually parallel vertical plates symmetrical along a center line of the transverse plates are connected between the two mutually parallel transverse plates along the length direction of the transverse plates, and all the transverse plates and the vertical plates are steel-plastic composite plates which are composed of plastic and metal nets composited in the plastic. The production method includes using metal strips as supporting materials to be connected into a framework in the shape of the H-beam, using metal wires for knitting metal wire net surfaces of the transverse plates and the vertical plates of the H-beam on the framework in the shape of the H-beam, using a mold for injection molding and blowing compressed air into the mold for blow molding, and cooling the outside of the mold by water. The steel-plastic composite H-beam has the advantages of high mechanical strength, large rigidity, no deformation, long service life, low energy consumption, low production cost, good surface smoothness and capability of completely substituting for a steel H-beam to serve as a bearing component.
Description
Technical field
The present invention relates to a kind of steel and mould composite I-beam and preparation method thereof, belong to building materials technology field.
Background technique
I-shape beam is a kind of purposes building materials very widely, and its structure forms for two parallel transverse slats that connected by riser, and its section is I-shaped, so be called as I-shape beam.Existing I-shape beam is girder steel, and its advantage is that intensity is high, load good, and its shortcoming is that cost is high, weight large, the easy oxidized corrosion in surface, and poor surface smoothness.
Summary of the invention
The purpose of this invention is to provide a kind of lightweight, cost is low, anticorrosive, surface finishment good, the steel that can substitute steel I-shaped beam is moulded composite I-beam and preparation method thereof.
Technical solution of the present invention is as follows:
I-shape beam of the present invention comprises two transverse slats that are parallel to each other, it is characterized in that: being connected with two center lines of take transverse slat along the length direction of transverse slat between two transverse slats that are parallel to each other is the symmetrical riser be parallel to each other, transverse slat and riser are composited steel and plastic decking, and described composited steel and plastic decking is to consist of plastics and the wire netting be compounded in plastics.
The making method of I-shape beam of the present invention is: the framework that connects into above-mentioned I-beam shape with metal row culture blocking materials, knit out the transverse slat of I-shape beam and the wire wire side of riser with wire on the framework of I-beam shape, there is the framework of the I-beam shape of wire wire side to put into mould woollen yarn knitting, with plastic extruder to injected plastic in mould, be blown into pressurized air simultaneously in mould, plastics are attached on each wire wire side of framework of I-beam shape, by the wire wire side, be wrapped in plastics fully, hollow molding, mould adopts water cooling outward.
Advantage of the present invention is: take full advantage of that steel Anti-pull-press intensity is high, thermal expansion coefficient is little and the advantage of the good toughness of plastics, lightweight, corrosion resistance and good, the steel of making is moulded composite I-beam, mechanical strength is high, rigidity is large, indeformable, long service life, energy consumption is low, cost of production is low, surface finishment is good, can substitute steel I-shaped beam fully and use as load-carrying member.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
The A-A that Fig. 2 is Fig. 1 is to sectional view.
Embodiment
With reference to accompanying drawing, I-shape beam of the present invention comprises two transverse slats that are parallel to each other 1, being connected with two center lines of take transverse slat along the length direction of transverse slat between two transverse slats that are parallel to each other is the symmetrical riser be parallel to each other 2, transverse slat and riser are composited steel and plastic decking, and described composited steel and plastic decking is to consist of plastics and the wire netting be compounded in plastics.
The reference raw material proportioning of plastic material of the present invention is as follows:
Polypropylene flame redardant 20～50wt%, polyethylene 40～70wt%, stabilizer 0.1～0.5wt%, oiling agent 0.1～0.5wt%, fire retardant 0.1～0.3wt%, wood powder 5～10wt%.
Because plastics technology is very ripe at present, so plastic material of the present invention is not limited to above-mentioned formula.
The making method of I-shape beam of the present invention is: be welded to connect into the framework 3 of above-mentioned I-beam shape as blocking materials with metal bar (reinforcing bar), knit out the transverse slat of I-shape beam and the wire wire side 4 of riser with wire on the framework 3 of I-beam shape, there is the framework of the I-beam shape of wire wire side to put into mould woollen yarn knitting, with plastic extruder to injected plastic in mould, be blown into pressurized air simultaneously in mould, plastics are attached on each wire wire side of framework of I-beam shape, by the wire wire side, be wrapped in plastics fully, hollow molding, mould adopts water cooling outward.
