Technical field
The present invention relates to bridge construction materials processing technology field, particularly a kind of bridge construction is processed with corrosion-resistant screw rod
Technique.
Background technology
Annual world steel corrosion loss accounts for more than the 10% of steel total output, the economy that industrially developed country's corrosion is caused
Loss accounts for more than the 2%~4% of total value of production in national economy；Advanced anticorrosion technique is researched and developed, to reduce the warp that corrosion is caused
The service life of Ji loss, extension steel and other metal materials and equipment, to promoting advanced technology, the most advanced branches of science and national defence work
The sustainable and harmonious development of the development of industry and national economy and social environment has particularly important meaning.Armored concrete
The component and connector of its steel construction of the bridge of structure, due to facing frost demolition, chemical attack, steel bar corrosion and alkali bone for a long time
The various factors for causing corrosion such as material reaction, are easier to the concrete structure for occurring to corrode and then destroy a bridge；Especially because
The effect of humidity, temperature and carbon dioxide, can cause the carbonization of concrete, along with oxygen, sulfur dioxide and chlorine etc. corrode
The effect of property medium can be further exacerbated by the corrosion of bridge steel structural unit and connector.
In the prior art, bridge construction mainly carries out anticorrosion with screw rod by carrying out zincizing processing on surface, still
The decay resistance of zincizing processing is limited, not as good as the corrosion resistance and good of Dacroment erosion shield, Dacroment also known as up to gram
Rust, high gram rust, Zinc-Chromium film etc., refer to be coated with the liquid treatment fluid containing compositions such as zinc metal sheet, aluminium flake, chromic anhybride, ethylene glycol
Metallic matrix, after high-temperature baking, in metal base surface formation, one layer has splendid corrosion proof non-decoration film.But,
Because the usual thickness of Dacroment erosion shield is thicker, bridge construction screw flight dimensions is easily influenceed, in reality
Being located at the blocked up Dacromet/steel at screw thread during use can peel off under the squeezing action of nut inner thread, and peel off
Dacromet/steel can put aside in nut inner thread, Dacroment at the screw flight for building that further destroys a bridge is applied
Layer, makes the Dacromet/steel at screw thread completely lose anti-corrosion capability.

Reason, makes screw flight end outer diameter tolerance meet processing request, and the external screw thread of screw rod is then machined by extrusion forming；
Step 2: the screw rod after step one is processed is placed in and focused in cage, focus on cage and be made up of fiberglass, and
Focusing on cage includes the circular scrolling side wall of tubular structure, and axial one end of circular scrolling side wall is provided with circular scrolling envelope
Lid, the axial other end of circular scrolling side wall, which is provided with circular scrolling bottom wall, circular scrolling side wall, is provided with some hollow outs
Corrosion protection handles hole；
It is immersed into Step 3: cage will be focused in grease treatment fluid, rotation, which focuses on cage, to be made to focus in cage
Screw rod is fully contacted with grease treatment fluid to remove the grease on surface, is then taken out and is focused on cage clear water spray removal surface
Grease treatment fluid, rotation again focuses on cage and drains the water of the screw surface focused in cage；
Step 4: the cage that focuses on after step 3 is handled is immersed into Dacroment masking liquid, rotation, which focuses on cage, to be made
The screw rod focused in cage fully contacts the coating for completing Dacroment masking liquid with Dacroment masking liquid, then takes out and focuses on cage
Excessive Dacroment masking liquid is drained by rotating；
Preheated Step 5: cage will be focused on and be sent to be heating and curing in stove, make to focus on the screw rod table in cage
The Dacroment masking liquid in face loses flowability, and then takes out the screw rod focused in cage, passes through screw thread secondary extrusion mould pair
Screw flight is extruded, and the Dacroment masking liquid at screw thread is uniformly flattened, screw rod then is fed again into the stove that is heating and curing
The Dacroment masking liquid of screw surface is fully cured in middle progress heating.
As the further improvement of above-mentioned technical proposal, in step 5, screw thread secondary extrusion mould includes extruding mold sleeve,
Extruding sliding groove is provided with extruding mold sleeve, one end of extruding sliding groove is provided with fixed press mould, extrudes the another of sliding groove

Inner threaded surface, which is collectively constituted, can coordinate the extruding internal thread of external thread of screw.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of bridge construction provided by the present invention passes through the Dacroment to screw surface with corrosion-resistant screw rod processing technology
Masking liquid, which carries out preheating volatile fraction solvent, makes Dacroment masking liquid lose flowability, then again to the Dacroment masking liquid at screw flight
Extruded, the Dacroment masking liquid at screw flight is uniformly flattened, then heat and make the Dacroment masking liquid of screw surface complete
All solidstate, so as to ensure that bridge construction screw flight dimensions well, is located in actual use
Dacromet/steel at screw thread will not be peeled off under the squeezing action of nut inner thread, accumulated, and make bridge construction screw rod in spiral shell
Dacromet/steel at line has preferable anti-corrosion capability；In addition, the bridge construction of the present invention processes work with corrosion-resistant screw rod
Skill focuses on cage from fiberglass, and screw rod can be not only handled in bulk, makes whole work efficiency high, and fiberglass
Focus on cage good corrosion resistance, easy to clean to safeguard, service life is long；It can make screw thread by the way of undergauge post-processing screw thread
Size is more accurate, it is to avoid influence of the tolerance of cast blank to thread size.
