Abstract
The utility model discloses a high-strength steel bar concrete pole which comprises a pole skeleton and a concrete layer wrapping the pole skeleton. The high-strength steel bar concrete pole is characterized in that more than six axial main ribs and reinforcing ribs used for connecting the axial main ribs are arranged on the pole skeleton , the reinforcing ribs are evenly arranged in the axial direction, and each axial main rib is a spiral U-steel bar or a spiral rib steel bar. Compared with the adoption of deformed steel bars or round steel, consumption of steel of the high-strength steel bar concrete pole is reduced by more than 30% in the condition of the same carry cargo, manufacturing cost is low, the weight of the high-strength steel bar concrete pole is greatly reduced, transport and installation are convenient, and the high-strength steel bar concrete pole can be widely applied to various occasions of reinforced concrete poles such as round poles and square poles.
Description
Technical field:
The utility model relates to electric pole, is specifically related to the high-strength steel bar concurrent.
Technical background:
Electric pole is the bridge of electricity, allows electricity be transported to each place, and we have wooden electric pole by common electric pole, and cement electric pole is arranged, and their height differs, and stands in the Plain intermountain, spreads over around the people.Total class of electric pole is a lot, and commonly used have a reinforced concrete pole, adopts concrete and skeleton to make, skeleton generally adopts screw-thread steel or round steel, because the tensile strength of screw-thread steel or round steel generally only has the hundreds of MPa, for satisfying the quality requirement of electric pole, the steel that need are many, and cost of manufacture is high.
The utility model content:
Technical problem to be solved in the utility model provides the low high-strength steel bar concurrent of cost of manufacture.
In order to address the above problem, technical solutions of the utility model are, the high-strength steel bar concurrent, the layer of concrete that comprises electric pole skeleton and this electric pole skeleton of parcel, be characterized in: described electric pole skeleton is provided with the axial main muscle and the reinforcing rib that is connected this axial main muscle more than 6, this reinforcing rib is evenly arranged along the axial, and described axial main muscle is helicla flute rod iron or spiral ribs rod iron.
Axial main muscle of the present utility model is helicla flute rod iron or spiral ribs rod iron, and under identical loading condition, the steel use amount is than adopting screw-thread steel or round steel to reduce more than 30%.
According to a kind of preferred version of high-strength steel bar concurrent described in the utility model, this electric pole is lower thick narrow rectangular shaft-like, and the electric pole cross section be circle or square.
The beneficial effect of high-strength steel bar concurrent described in the utility model is: axial main muscle of the present utility model is helicla flute rod iron or spiral ribs rod iron, under identical loading condition, the steel use amount is than adopting screw-thread steel or round steel to reduce more than 30%, cost of manufacture reduces, electric pole weight significantly alleviates, convenient transportation and installation; Can be widely used in comprising the various reinforced concrete pole occasions such as round bar, square bar.
Description of drawings
Fig. 1 is the sectional view of high-strength steel bar concurrent described in the utility model.
The A-A face sectional view of Fig. 2 Fig. 1 that is the electric pole cross section when circular.
Fig. 3 is the A-A face sectional view of electric pole cross section Fig. 1 when being square.
The specific embodiment
Referring to Fig. 1 to Fig. 3, the high-strength steel bar concurrent, the electric pole cross section is circular or square, this electric pole comprises the layer of concrete of electric pole skeleton and this electric pole skeleton of parcel, described electric pole skeleton is provided with the axial main muscle 1 and the reinforcing rib 2 that is connected this axial main muscle more than 6, and this reinforcing rib 2 is evenly arranged along the axial, and described axial main muscle 1 is helicla flute rod iron or spiral ribs rod iron, this rod iron tensile strength adopts 1570MPa or 1420MPa, and satisfies the GB/T5223 requirement.
Claims (2)
