Abstract

A high strength steel web glass steel bridge frame is a tray type and ladder type bridge frame used for an electric power and communication management cable. The bridge frame is connected into a whole by two edges (1) and a bottom plate (2) or a ladder rung, wherein the edges (1) adopts an I-shaped structure as a whole and are respectively provided with an upper and a lower abdominal cavities (11), insertion grooves (12) of the bottom plate (2) or the ladder rung are left on the lower parts at the inner sides of the edges (1), and two sides of the bottom plate (2) or the ladder rung are respectively inserted in the insertion grooves (12) on the lower parts at the inner sides of the two edges (1). Steel plates or sectional materials are inserted in the upper and the lower abdominal cavities (11) of the edges (1), a tubular strengthening rib (21) of the bottom plate (2) or a tubular ladder rung (3). The utility model solves the problems that a glass steel plate has low structural intensity and is easy to tear, and combines the advantages on two aspects that the glass steel material has light weight, corrosion resistance, good insulativity and wave transmission; and the glass steel material is tensile and antitorque and has high intensity; in addition, the utility model solves the problems that composite bridge frame steel and plastic materials are hard to separate, recover and reuse and have high cost and construction cost.

Description

High strength steel abdomen glass fiber reinforced plastic bridge

Technical field

The utility model is a kind of pellet type and ladder type crane span structure that is used for electric power, communication management cable, belongs to the technical field that the electric apparatus annex is made.

Background technology

Unsaturated polyester resin (UPR) adds the fiberglass cable bridge rack that glass fibre strengthens and has been widely used in chemical heavy corrosion industrial and mining enterprises such as soda acid, and its advantage is that in light weight, corrosion-resistant, insulation and wave penetrate capability are good.At present, the glass fiber reinforced plastic bridge of domestic production mainly is the full matter glass fiber reinforced plastic bridge by mechanical mold pressing and pultrusion.Because the base plate of full matter glass fiber reinforced plastic bridge adopts dull and stereotyped, side board adopts I-shaped structure, integrally-built bearing capacity and intensity mainly are to lean on the thickness of material to guarantee that although its thickness is more than three times of steel, its tension, bending resistance, anti-twisting property can not be compared with the steel cable testing bridge.For increasing crane span structure rigidity intensity and improving bearing capacity, it is base material that the product that has adopts steel plate, adds compound resin on the surface of steel plate, is called for short compound crane span structure, makes crane span structure existing steel crane span structure rigidity and intensity, and the antiseptic property of glass fiber reinforced plastics product is arranged again.More than two kinds of crane span structure shortcomings as follows:

1, full matter glass fiber reinforced plastic bridge is because base plate is dull and stereotyped, though resin is by chemical crosslinking, but glass fibre exists warp and parallel to be subjected to the difference of force intensity, the crane span structure flat underside is in a single day stressed, and the centre of baseplate width direction will be bent downwardly, and the phenomenon of tearing along warp direction often takes place, the inclination that makes I shape group limit produce vertical direction, make two to help carrying center, limit to be offset, therefore distortion, the serious hidden danger that there is fracture in whole crane span structure or caves in appear in I shape group limit.

2, the general employing of compound crane span structure made by hand, and efficient is low, cost is high, and cost is 2-3 a times of common product, because resin is to be compounded on the steel plate, bonding technology requires very high, in case the bad phenomenon of peeling off that just exists of adhesion.Compound crane span structure after using is because composite material is difficult to separate, and not only steel plate can not reclaim, and the fiberglass part can not be utilized again, causes serious environmental to pollute.Along with the raising of social enviroment protection consciousness, from now on as adopting compound crane span structure to bring expensive solid refuse disposal cost to the user.

Summary of the invention

Technical problem: goal of the invention of the present utility model provides a kind of tear-proof, corrosion resistant high strength steel abdomen glass fiber reinforced plastic bridge.

Technical scheme: high strength steel abdomen glass fiber reinforced plastic bridge of the present utility model helps limits and base plate or terraced Guang to connect into an integral body by two, the whole I-shaped structure that adopts in group limit, an abdominal cavity is respectively arranged up and down, leave the insertion groove of base plate or terraced Guang in the inboard bottom in group limit, the both sides of base plate or terraced Guang are inserted two inboard following insertion grooves in group limit respectively, are provided with connecting hole at I shape group two ends, limit.

Described base plate adopts the base plate to Width band tubulose reinforcement to form the pellet type crane span structure, and according to using needs can on base plate, increase air-vent.

Described terraced Guang adopts tubulose ladder Guang to form the ladder type crane span structure.

In the tubulose reinforcement of abdominal cavity up and down, the base plate on group limit or tubulose ladder Guang, insert steel plate or section bar.

Beneficial effect: high strength steel abdomen glass fiber reinforced plastic bridge of the present utility model has solved the problem that fiberglass slab construction intensity is low, easily tear; Combine that glass-reinforced plastic material is in light weight, corrosion-resistant, insulation and wave is good and steel tension, antitorque, two aspect advantages that intensity is high; From the angle of the mechanics of materials portal structure is carried out creationary design, base plate and tubulose ladder Guang with tubulose reinforcement high-strength structure replace dull and stereotyped base arrangement and the opening terraced Guang structure of real abdomen, replace the I-shaped structure of real abdomen up and down with rectangle abdominal cavity I-shaped structure up and down, the glass fiber reinforced plastic bridge rigidity intensity that adds the steel abdomen is through Mechanics Calculation, be that full matter glass fiber reinforced plastic bridge is more than 5 times, make product reach perfect fusion, have the advantage that weight is lighter, intensity is higher, cost is lower compared with similar products; Overcome the weakness that full matter glass fiber reinforced plastic bridge exists aspect rigidity intensity and bearing capacity, solved that compound crane span structure steel, moulding material are difficult to separate, the problem of recycling.

Embodiment

High strength steel abdomen glass fiber reinforced plastic bridge of the present utility model helps limits and base plate or terraced Guang to connect into an integral body by two.The whole I shape that adopts in group limit respectively has a rectangle abdominal cavity up and down, at the insertion groove that inboard bottom leaves base plate and terraced Guang, helps the two ends, limit to be provided with connecting hole.The pellet type crane span structure adopts the base plate to Width band tubulose reinforcement, and the ladder type crane span structure adopts tubulose ladder Guang, and base plate and terraced Guang are inserted and secured in the insertion groove of two group inboards, limit.According to specification size and the rigidity intensity and the requirement for bearing capacity of crane span structure, can insert steel plate or section bar in abdominal cavity, base plate tubulose reinforcement or the tubulose ladder Guang up and down on the group limit, can not insert yet.
