Abstract
The utility model discloses a tubular joint for flange sleeves of a steel tube tower. The tubular joint comprises two crossed steel tube diagonal members, wherein one steel tube diagonal member is broken into two parts at a crossed point of the two steel tube diagonal members, the other steel tube diagonal member is not broken and is externally sleeved with a flange sleeve at the crossed part, and two parts of the broken steel tube diagonal member are respectively welded on the outer wall of the flange sleeve. According to the utility model, the purpose of enhancing joint strength is achieved by means of selecting the flange sleeve and bolts, the purpose of enhancing the joint rigidity is achieved by means of intersected welding between the flange sleeve and the broken steel tube diagonal member, the purpose of not connecting the joint with the non-broken steel tube diagonal member is achieved by making the non-broken steel tube diagonal member penetrate through the flange sleeve directly at the crossed point, and in addition, a pair of flange sleeves is adopted only, so that materials are saved; and the specification of the steel tube diagonal members is not increased while the joint strength and the joint rigidity are enhanced, and the advantages of low material consumption and simple structure is achieved.
Description
Technical field
The utility model relates to a kind of steel tube tower node, especially steel tube tower flange sleeve tubular joint.
Background technology
At present, to intersect Types of nodes that the oblique material of steel pipe intersects be that round flange passes through mutually to connect and is connected with plate for two of known steel tube towers.Structure is to disconnect wherein oblique material of steel pipe at the two oblique material intersection point of intersection steel pipe places, and crossed node adopts two pairs to be that four round flanges or plate connect the oblique material of disconnection steel pipe, and crossed node is welded on another root and does not disconnect on the oblique material of steel pipe.But, the former increases the oblique material specification of steel pipe sometimes because node strength is not enough, the latter increases the oblique material specification of steel pipe because of the node insufficient rigidity sometimes, simultaneously, both all adopt two pairs of connectors (flange or plate), material usage is many, and crossed node need to do not disconnect the oblique material of steel pipe and be welded to connect complex structure.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of steel tube tower flange sleeve tubular joint is provided, this node not only intensity is high, and rigidity is large, can be because of node strength or insufficient rigidity and the oblique material specification of steel pipe that increases, simultaneously, this node only adopts a pair of i.e. two flange sleeves, material usage is few, and does not need and do not disconnect the oblique material of steel pipe and be connected, and is simple in structure.
For achieving the above object, the utility model adopts following technical proposals:
A kind of steel tube tower flange sleeve tubular joint, comprise two oblique materials of steel pipe arranged in a crossed manner, wherein the oblique material of steel pipe is broken as two parts at both intersection point places, the oblique material of another root steel pipe does not disconnect, the oblique material intersection point of the steel pipe place outer cover that does not disconnect has a flange sleeve, and the oblique material of two parts steel pipe of disconnection is welded on respectively on the flange sleeve outer wall.
Described flange sleeve is combined by two parts connection of symmetry, and every part includes semicircular pipe, and two edges of semicircular pipe are welded with respectively the flanged plate of a level, and the two ends of semicircular pipe and flanged plate all are welded with stiffening ring; Two parts of described symmetry are bolted flanged plate and form a tubular construction.
The semi-circle tubular structure of described semicircular pipe for being made by steel plate bending, flanged plate is the rectangular steel plates in strap bolt hole, stiffening ring is the semicircle doughnut-shaped steel plate.
The oblique material of two parts steel pipe of described disconnection passes through mutually respectively and is welded on the flange sleeve outer wall.
The internal diameter of described flange sleeve is greater than the external diameter of the oblique material of steel pipe that does not disconnect.
During application, disconnect wherein oblique material of steel pipe at the two oblique material intersection point of intersection steel pipe places, another root does not disconnect, the crossed node place adopts a pair of i.e. two flange sleeves to connect the oblique material of described disconnection steel pipe, form diameter between two flange sleeves greater than the described cylindrical space that does not disconnect two millimeters of the oblique material external diameters of steel pipe, do not disconnect the oblique material of steel pipe and directly pass two flange sleeves at the intersection point place.Flange sleeve passes through mutually with the oblique material of disconnection steel pipe and is welded to connect.
By choosing the purpose that flange sleeve and bolt have reached increases node strength, pass through mutually the purpose that welding has reached increases node rigidity by flange sleeve and the oblique material of disconnection steel pipe, by do not disconnect the oblique material of steel pipe directly pass at the intersection point place flange sleeve reached node not with the purpose that does not disconnect the oblique material of steel pipe and be connected, only adopt in addition a pair of flange sleeve, save material.
The beneficial effects of the utility model are, can be when increasing node strength and rigidity and do not increase the specification of the oblique material of steel pipe, and material usage is few, and is simple in structure.
