In recent years, the construction of voltage levels transmission line of electricity is in full swing, and along with the raising of electric pressure, steel tube tower has obtained unprecedented application in ultrahigh voltage alternating current transmission lines.Plate is that steel tube tower is responsible for a kind of mode that is connected with arm.Be connected with the junction plate bolt by plate, arm is connected on the person in charge.Be responsible for and the arm co-operation, become a force structure---steel tube tower.Exist in the design of prior art and be difficult to satisfy intensity and rigidity requirement and inconvenience processing, installation and maintenance.Still on AC extra high voltage circuit steel tube tower, do not use the type of attachment of cross plate.
The utility model content
The purpose of this utility model is to provide a kind of cross plate node that uses on AC extra high voltage circuit steel tube tower.
The utility model has been described a kind of node that is used for steel tube tower, it is characterized in that, described node comprises: arm, and its end that is used to connect has cross recess, and groove depth is not less than the length that the weld seam Force Calculation requires; Partly be inserted into described cross recessed cross plate with welding manner, wherein said cross plate does not insert described each limb of cross recess part and is provided with one or more bolts hole; Be responsible for; Be welded to person in charge's cross connecting plate of the described person in charge, the section of described person in charge's cross connecting plate is cross, and the one end is welded on the described person in charge, and with each limb of the other end that described cross plate is connected on be provided with one or more bolts hole; Be provided with the junction plate of bolt hole, bolt hole on the described junction plate is corresponding with the bolt hole on described cross plate and the described person in charge's cross connecting plate, to be used for utilizing bolt to connect described cross plate and described person in charge's cross connecting plate by described junction plate, wherein when connecting, described cross plate is with described person in charge's cross connecting plate butt joint and utilize described junction plate to carry out two-sided the connection with bolt.
Preferably, described person in charge's cross connecting plate and described cross plate uniform thickness.
Preferably, described person in charge's cross connecting plate and described cross plate uniform thickness not.
Preferably, bolt hole number on each limb of described cross plate and arrangement are identical with person in charge's cross connecting plate;
Preferably, bolt hole number on each limb of described cross plate or arrangement and person in charge's cross connecting plate are inequality.
Advantage of the present utility model is: this node satisfies structure design to intensity and rigidity requirement, is convenient to processing, construction and installation and maintenance.
