The parallel connection joint of X-braced panels in a kind of steel tube tower in electric transmission line
Technical field:
The present invention relates to the connection structure field in steel tube tower in electric transmission line, relate more specifically to the parallel connection joint of X-braced panels in a kind of steel tube tower in electric transmission line.
Background technology:
It is to pass through mutually soldered connecing that the X-braced panels that steel tube tower is conventional connects pattern, pass through mutually weldering welding difficulty larger, and can cause the consumption of flange large, also be unfavorable for field transportation and install, adopt plate to connect and can effectively reduce difficulty of processing, steel using amount is corresponding reduction also, but adopt under plate connection, the rigidity of connected node decreases, and need to consider the local yielding problem of node, and adopting annular stiffener is conventional method.Conventional plate connects when two steel pipe angles are when larger, and annular stiffener differs greatly to being connected the junction plate constraint of steel pipe both sides, easily cause constraint a little less than a side Joint failure, whole stressed harmony is not ideal enough.
Summary of the invention:
The parallel connection joint that the object of this invention is to provide X-braced panels in a kind of steel tube tower in electric transmission line, the present invention changes conventional annular stiffener into pattern that annular stiffener is parallel to joint steel pipe perpendicular to the pattern that is connected steel pipe, improves the stress performance that plate connects connected node.
For achieving the above object, the present invention is by the following technical solutions:
The parallel connection joint of X-braced panels in a kind of steel tube tower in electric transmission line provided by the invention, comprise and be connected steel pipe and joint steel pipe, the described steel pipe that is connected is provided with two gusset plates, described two gusset plate plate faces are in same plane, described two gusset plates are about the described steel pipe axial line symmetry that is connected, the normal of described gusset plate with described in to be connected steel pipe axial line vertical, on described gusset plate, have screwed hole; Described joint steel pipe is provided with grooved plate, and one end of described grooved plate is inserted and fixes from the mid point of described joint steel pipe one end axial direction, on described grooved plate, has screwed hole; The plate face of described gusset plate is parallel with the plate face of described grooved plate, described in be connected on the gusset plate at steel pipe two ends and be connected with respectively a grooved plate, adopt bolt to fix, the joint steel pipe concentric on described two grooved plates; Described being connected is also provided with two annular stiffeners on steel pipe, described be connected the axis of steel pipe, the normal of the axis of joint steel pipe and annular stiffener plate face in same plane, between described two annular stiffeners, be gusset plate, described annular stiffener plate face and described joint steel pipe axis parallel.
In a kind of steel tube tower in electric transmission line provided by the invention, in the parallel connection joint technical scheme of X-braced panels, described gusset plate, grooved plate and annular stiffener are the plate of even thickness.
In another preferred a kind of steel tube tower in electric transmission line provided by the invention in the parallel connection joint technical scheme of X-braced panels, at the width of grooved plate plate face described in the radial direction of described joint steel pipe, be greater than the external diameter of described joint steel pipe, described grooved plate two ends are symmetrical about the axle center of joint steel pipe.
In a preferred a kind of steel tube tower in electric transmission line more provided by the invention in the parallel connection joint technical scheme of X-braced panels, described in be connected between steel pipe and gusset plate, described joint steel pipe and grooved plate and described annular stiffener and described gusset plate and all adopt and be welded and fixed.
In another preferred a kind of steel tube tower in electric transmission line provided by the invention in the parallel connection joint technical scheme of X-braced panels, on described gusset plate, have at least four screwed holes, on described grooved plate, have the screwed hole corresponding with gusset plate, described gusset plate and grooved plate adopt bolt to fix.
In another preferred a kind of steel tube tower in electric transmission line provided by the invention in the parallel connection joint technical scheme of X-braced panels, at the above grooved plate plate face of radial direction of joint steel pipe, with respect to the wide part out of external diameter of joint steel pipe, to one end, bend to right angle.
Owing to having adopted technique scheme, the beneficial effect that the present invention obtains is:
In steel tube tower, X-braced panels connects the safety whether effective force is directly connected to whole steel tower, the pattern that the present invention adopts annular stiffener to be parallel to joint steel pipe replaces conventional annular stiffener perpendicular to the pattern that is connected steel pipe, make stiffener be parallel to power transmission center line, experimental study shows, transmission force property of the present invention is more superior.

The specific embodiment
Below in conjunction with embodiment, the invention will be described in further detail.
Embodiment 1:
As shown in Fig. 1-7, the parallel connection joint of X-braced panels in a kind of steel tube tower in electric transmission line of invention of this example, comprise and be connected steel pipe 1 and joint steel pipe 2, be connected steel pipe 1 and be provided with two gusset plates 4, two gusset plate 4 plate faces are in same plane, two gusset plates 4 are symmetrical about being connected steel pipe 1 axial line, and the normal of gusset plate 4, with to be connected steel pipe 1 axial line vertical, has screwed hole on gusset plate 4; Joint steel pipe 2 is provided with grooved plate 3, and one end of grooved plate 3 is inserted and fixes from the mid point of joint steel pipe 2 one end axial directions, on grooved plate 3, has screwed hole; The plate face of gusset plate 4 is parallel with the plate face of grooved plate 3, is connected on the gusset plate 4 at steel pipe 1 two ends and is connected with respectively a grooved plate 3, adopts bolt 6 fixing, joint steel pipe 2 concentrics on two grooved plates 3; Be connected and on steel pipe 1, be also provided with two annular stiffeners 5, be connected the axis of steel pipe 1, the normal of the axis of joint steel pipe 2 and annular stiffener 5 plate faces in same plane, between two annular stiffeners 5, be gusset plate 4, annular stiffener 5 plate faces and joint steel pipe 2 axis parallels; Gusset plate 4, grooved plate 3 and annular stiffener 5 are the plate of even thickness; The external diameter, grooved plate 3 two ends that at the width of the radial direction grooved plate 3 plate faces of joint steel pipe 2, are greater than joint steel pipe 2 are symmetrical about the axle center of joint steel pipe 2; Be connected between steel pipe 1 and gusset plate 4, joint steel pipe 2 and grooved plate 3 and annular stiffener 5 and gusset plate 4 and all adopt and be welded and fixed; On gusset plate 4, have at least four screwed holes, the quantity of screwed hole can need corresponding increasing according to intensity, has the screwed hole corresponding with gusset plate 4 on grooved plate 3, and gusset plate 4 adopts bolt to fix with grooved plate 3; At the plate of the grooved in the radial direction 3 plate faces of joint steel pipe 2, with respect to the wide part out of external diameter of joint steel pipe 2, to one end, bend to right angle; θ is the angle that is connected steel pipe 1 and joint steel pipe 2.
Be connected when steel pipe 1 is connected in joint steel pipe 2 and can take following steps, grooved plate 3 and joint steel pipe 2 welding form grooved plate joint, two gusset plates 4 are welded in respectively and are connected steel pipe 1 both sides and adopt bolt 6 to be connected with grooved plate joint respectively, annular stiffener 5 is welded in respectively two gusset plates 4 and the junction that is connected steel pipe 1, plays the effect to joint strengthening.
