Abstract
The utility model relates to an inserted type inner flange connecting steel pipe tower, which comprises an upper segment tower pipe and a lower segment tower pipe connected in an inserting manner. The steel pipe tower is characterized in that a positioning mechanism used for positioning the tower pipe when the steel tower is mounted is respectively arranged on the connecting parts of the upper segment tower pipe and the lower segment tower pipe; and inner flange connections are adopted between the upper segment tower pipe and the lower segment tower pipe. Under the positioning effect of the positioning mechanisms, the upper segment tower pipe and the lower segment tower pipe can be mounted and positioned conveniently, and the positioning mechanism plays a fixing function, thereby reducing the bolts for inner flange connection, saving the material, and reducing the cost; the welding is not required, so that the construction operation is convenient, and the inner flange connecting steel pipe tower is applicable to field working; and meanwhile, the inner flange connection is favorable for burglary prevention.
Description
Technical field
The utility model relates to the iron tower field, refers to that specifically the plug-in type inner flange connects steel tube tower.
Background technology
The iron tower of building normally adopts the method that steel pipe is pegged graft at present.Traditional steel pipe connected mode has plug-in type, outward flange formula and inner flange type.Wherein plug-in type is to adopt welding manner that two steel pipes are connected and fixed, and this connected mode steel duct welding is extremely inconvenient, and field work will be subjected to the restriction of electricity consumption, constructional difficulties.Especially welding inner after two sections steel pipes are pegged graft is very convenient.Plug-in type generally is used for the connection between the bigbore steel pipe.Another kind of connected mode is the outward flange formula, and normally the less steel pipe of diameter adopts this mode to connect, and in order to be connected firmly, flange is bigger, and weld is more, not only influences attractive in appearancely, and the junction bolt exposes very easily stolen.Another connected mode is an inner flange type, and normally large diameter steel pipe adopts this mode to connect, and in order being connected firmly, to prevent down, to break, and is very high to thickness, welding and the bolt requirement of inner flange, and because required bolt is more, installs very consuming time.What inner flange type connected employing also is the steel duct welding.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provide a kind of easy for installation, be beneficial to antitheft, materials are few and the plug-in type inner flange of suitable field work connects steel tube tower.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this plug-in type inner flange connects steel tube tower, comprise epimere tower pipe and hypomere tower pipe that plug-in type connects, it is characterized in that: the corresponding respectively detent mechanism that is provided with Positioning Tower pipe when being used for the iron tower installation in the junction of described epimere tower pipe and hypomere tower pipe, and epimere tower pipe adopts inner flange to be connected with hypomere tower pipe junction.
Plug-in type inner flange provided by the utility model connects steel tube tower under the positioning action of detent mechanism, but epimere tower pipe and hypomere tower pipe be installing and locating just very easily, and detent mechanism also can play fixation, has reduced inner flange and has connected and use bolt, materials are saved, and have reduced cost; And need not weld, constructing operation is convenient, especially is fit to field work; The connected mode of inner flange is to antitheft highly beneficial simultaneously.
Described detent mechanism can adopt multiple mode, for example the cooperation of chute and guide rail; Preferably, described detent mechanism can be arranged on two groove and projections on the steel pipe for correspondence.This is relatively simple for structure, processing easily, and also the location of groove and projection is accurate rapidly, need not the high-altitude rotation and adjusts, and has solved the problem that is difficult to when inner flange connects the hole, and time saving and energy saving.
As the further improvement of such scheme, stop that rainwater leaks the rain wing that enters hypomere tower pipe being welded with on the described epimere tower pipe near the outside of hypomere tower pipe.
Compared with prior art, advantage of the present utility model is to be provided with detent mechanism in the junction of adjacent epimere tower pipe and hypomere tower pipe, efficiently solves the difficult problem in work high above the ground tower pipe grafting location; And inner flange connects with bolt less, and materials are saved, and have reduced cost, and does not need welding, is fit to field work; And the design of the rain wing can effectively stop rainwater to bleed the head tower pipe, has prolonged the life-span of iron tower.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of the utility model embodiment;
Fig. 2 is along the sectional view of A-A line among Fig. 1;
Fig. 3 is the partial enlarged drawing of B part among Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Iron tower has the cylindrical or hexagon of more piece different-diameter or eight prismatic tower pipes to peg graft to form usually, and the internal diameter and the hypomere tower external diameter of pipe of two adjacent epimere tower pipes match, to make things convenient for its grafting.As shown in Figure 1 to Figure 3, the plug-in type inner flange in the present embodiment connects in the columniform hypomere tower pipe 2 of cylindrical epimere tower pipe 1 insertion of steel tube tower.
As depicted in figs. 1 and 2, the junction of epimere tower pipe 1 is provided with projection 3 at the two ends of diameter, corresponding, on hypomere tower pipe 2, be provided with groove 4.The detent mechanism of Positioning Tower pipe when described projection 3 and groove 4 constitute the iron tower installation.
As depicted in figs. 1 and 2, in order to prevent that rainy day, rainwater leaked in the hypomere tower pipe 2, on the epimere tower pipe 1, weld the rainy wing 5 near the outside of hypomere tower pipe, the rain wing 5 is along the circumferencial direction welding of epimere tower pipe 1.
As Fig. 2 and as shown in Figure 3, owing to adopt plug-in type, inner flange 6 need not or only need bear less shearing force, so required reinforcing rib is less on the flange, has saved cost; And easy for installation, the bolt consumption is few, only needs 4～8, only connects half of used bolt for the conventional flange formula, and need not weld, and installation exercise is not subjected to power limitations, makes things convenient for field work.
During installation, earlier the rain wing 5 is welded, then epimere tower pipe 1 is inserted in the hypomere tower pipe 2, rotate epimere tower pipe 1 gently, projection 3 is snapped in the groove 4, can locate the installation site of epimere tower pipe and hypomere tower pipe.Then that inner flange 6 usefulness bolt are good, the installation of this two adjacent tower pipe is promptly accused and is finished.Simple to operation, and, be not subjected to the restriction of power supply because do not need welding, be fit to very much field work.
