Abstract

The utility model discloses a connecting structure of newly added beams of an open-air switching station tower. Original beam connecting angle steel (a) is connected with newly added overhang angle steel (1) through bolts; the newly added overhang angle steel (1) is connected with additional overhang angle steel (3) through bolts; newly added gusset plates (2) are welded with original gusset plates (b); and a lining plate (4) is added to the back of each newly added gusset plate (2). End angle steel of the newly added beams is directly connected with the additional overhang angle steel (3), and the beams are reasonable in stress and convenient in construction. During extension of a switching station, the problems of structural calculation and construction of the newly added beams on one side of the tower without beams are solved, and additional connecting angle steel is added on newly added connecting angle steel, so that the end angle steel of the newly added beams does not need to be in a fold line shape.

Description

The syndeton of the newly-increased crossbeam of open-air switching station pylon

Technical field

The utility model relates to the syndeton of the newly-increased crossbeam of a kind of open-air switching station pylon.

Background technology

Run into the problem of enlarging in the open in the switching station process of construction through regular meeting; the newly-increased crossbeam of a side that does not promptly have crossbeam at original support; so because be not the problem that engineering all can be considered enlarging; so the joint does not have to reserve the gusset plate be connected with newly-increased crossbeam and angle steel often; therefore the problem that needs to solve is exactly connecting angle and the connected node plate that how to increase herein; engineering in the past is to increase a connecting angle with bolt on original and angle steel that crossbeam is connected; on connecting angle, directly connect newly-increased crossbeam again; newly-increased like this crossbeam will be made broken line shape (seeing accompanying drawing 1) in the joint; could be connected with connecting angle; but this way is made broken line shape to the beam-end rod member; crossbeam is stressed unreasonable, and construction is also inconvenient.

Summary of the invention

Technical problem to be solved in the utility model is, the syndeton of the newly-increased crossbeam of a kind of open-air switching station pylon is provided, and makes broken line shape to overcome the beam-end rod member that prior art exists, and crossbeam is stressed unreasonable, deficiencies such as the inconvenience of constructing also.

The technical solution of the utility model is: original crossbeam connecting angle connects and newly adds the angle steel of encorbelmenting, and newly adds the angle steel of encorbelmenting and is connected with the additional angle steel of encorbelmenting, and newly adds gusset plate and original gusset plate and welds, and adds liner plate newly adding node backboard face.

Original crossbeam connecting angle with newly add the angle steel of encorbelmenting, newly add the angle steel of encorbelmenting and adopt bolt to be connected between the angle steel with additional encorbelmenting.

Compared with prior art, the utility model makes in switching station enlarging process, structural calculation and construction problem that pylon does not have the newly-increased crossbeam of crossbeam one side are resolved, on newly-increased connecting angle, increased additional connecting angle, it goes without doing becomes broken line shape just can be connected by direct and additional connecting angle for the end angle steel of newly-increased like this crossbeam, crossbeam is stressed rationally, and easy construction.

The specific embodiment

Embodiment of the present utility model: do not have at original support on original crossbeam connecting angle a of crossbeam one side with the bolt increase and newly add the angle steel 1 of encorbelmenting, newly add gusset plate 2 and original gusset plate b welding (back side adds liner plate 4), newly adding on the angle steel 1 of encorbelmenting with the additional angle steel 3 of encorbelmenting of bolt, newly-increased beam-end angle steel just directly and add the angle steel 3 of encorbelmenting and be connected again.

Claims

1. the syndeton of the newly-increased crossbeam of an open-air switching station pylon, it is characterized in that: original crossbeam connecting angle (a) connects and newly adds the angle steel of encorbelmenting (1), newly adding the angle steel of encorbelmenting (1) is connected with the additional angle steel (3) of encorbelmenting, newly add the welding of gusset plate (2) and original gusset plate (b), add liner plate (4) newly adding gusset plate (2) back side.

2. the syndeton of the newly-increased crossbeam of open-air switching station pylon according to claim 1 is characterized in that: original crossbeam connecting angle (a) with newly add the angle steel of encorbelmenting (1), newly add the angle steel of encorbelmenting (1) and encorbelment that the employing bolt is connected between the angle steel (3) with adding.
