Abstract
The utility model relates to an epiboly concrete steel pipe tower which is composed of a plurality of epiboly concrete steel pipe sections, wherein, the connection parts of the epiboly concrete steel pipe sections are provided with flanges for connection, steel rings and ribbed slabs. The epiboly concrete steel pipe tower has the advantages of high intensity and low manufacture cost. In addition, the large-area treatment for rust and corrosion resistance of metals does not need to be done. The utility model is widely suitable for overhead power delivery lines, and is particularly for overhead power delivery lines in cities.
Description
The external wrapping concrete steel tube tower belongs to the supporter that uses in the aerial power transmission line.
At present, the supporter that uses in the power transmission sequence mainly contains reinforced concrete pole, angle steel tower, steel tube tower etc.The reinforced concrete pole insufficient strength, and angle steel tower and steel tube tower just involve great expense.The thin wall steel tube concrete bar that Chinese patent provides for No. 90208878.5, though existing certain intensity, cost is also not very expensive, because its thin-wall steel tube is exposed among the air, must carry out antirust, preservative treatment outward, trouble and will increase cost.
The purpose of this utility model is to provide a kind of intensity enough, low cost, needn't carry out antirust, preservative treatment, the external wrapping concrete steel tube tower that floor space is little in the use.
The utility model is realized by following proposal: do bone with steel pipe, the outside encases with steel concrete, makes external wrapping concrete steel pipe joint, forms the external wrapping concrete steel tube tower with number joint external wrapping concrete steel pipe joint.The upper/lower terminal of every joint all leaves to connect uses flange, between the flange with welding with electric welding again after the Bolt Connection.Whole steel tube tower is down thick thin, the bottom of next joint and go up a top of saving most and do not stay flange, and use concrete enclosing.
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing 1 is an external wrapping concrete steel pipe joint schematic diagram.
Accompanying drawing 2 is that A is to schematic diagram.
Accompanying drawing 3 is B-B face cross-sectional schematic.
Accompanying drawing 4 is C-C face cross-sectional schematic.
In the accompanying drawings, [1] is gusset, and [2] are flange, and [3] are steel rings, and [4] are screws, and [5] are steel pipes, and [6] are trivet iron, and [7] are main muscle, and [8] are spiral bars, and [9] are screw-thread steels.Gusset [1] has some, and all weld with electric welding the junction of it and flange [2], steel ring [3], steel pipe [5].Screw-thread steel [9] welds together with main muscle [7].The two ends of main muscle [7] and steel ring [3] welding.Steel ring [3], flange [2] all weld with steel pipe [5].Trivet iron [6] also is welded in the two ends of steel pipe [5].Enrich with high-intensity concrete the outside of steel pipe [5], makes main muscle [7], spiral bar [8], screw-thread steel [9], steel pipe [5] and concrete form a cylinder that has certain taper together.Whole external wrapping concrete steel tube tower saves external wrapping concrete steel pipe joint by number to be formed, and thick down going up carefully generally all made 1/75 taper, with bolt flange [2] tightened up earlier between joint and the joint, welds with two flange that tighten up of electric weld handle [2] again.Descend most the bottom of external wrapping concrete steel pipe joint of joint and the top of going up the external wrapping concrete steel pipe joint of joint most all not to want gusset [1] and flange [2], get final product and steel ring [3] and trivet iron [6] are sealed with concrete, certainly, at this moment steel ring [3] position that should be put into flange [2] is gone.
The utility model intensity height, cost are low, needn't carry out large-area antirust, anti-corrosive again and handle, and can be widely used among the aerial power transmission line, particularly the power transmission sequence within the city.
Claims (3)
1. external wrapping concrete steel tube tower, formed by number joint external wrapping concrete steel pipe joint, it is characterized in that: in every joint external wrapping concrete steel pipe joint, steel pipe [5] is arranged all, steel pipe [5] is outer to be concrete, be equipped with main muscle [7], spiral bar [8], screw-thread steel [9] in the concrete, be welded with trivet iron [6] in the two ends pipe of steel pipe [5], the outside at steel pipe [5] two ends is welded with steel ring [3], flange [2], gusset [1].
2, external wrapping concrete steel tube tower as claimed in claim 1, it is characterized in that: steel tube tower descends the bottom of joint external wrapping concrete steel pipe joint most and goes up the top that joint external wrapping concrete steel pipe saves does not most have flange [2] and gusset [1], and seals steel ring [3] and trivet iron [6] with concrete.
3, external wrapping concrete steel tube tower as claimed in claim 1 is characterized in that: not only use bolt between every joint external wrapping concrete steel pipe joint, but also two flange [2] that the electricity consumption solid welding is tightly joined.
