The utility model discloses do not need the transition of oblique cross-section variable diameter, the connected node edges and corners are clear, and the node is dull and stereotyped, makes things convenient for various component side directions to connect.
Description
Technical Field
The utility model relates to a building structure field, concretely relates to square steel pipe and circular steel tube's nodal connection is a connection structure of square steel pipe and circular steel tube.
Background
The square steel pipe is connected with the node of the round steel pipe in the steel structure engineering, a hemispherical dome is usually adopted, the oblique section diameter-variable transition is carried out from the square steel pipe to the round steel pipe, and the manufacturing difficulty is higher. The inclined surface at the node is not allowed sometimes for the requirement of building aesthetics, even the lateral butt welding connection is arranged at the node, the butt joint must be ensured, and the inclined section diameter-variable transition cannot be realized at the moment.
Disclosure of Invention
An object of the utility model is to solve above-mentioned difficult problem, provide a connection structure of square steel pipe and circular steel tube.
The above object of the present invention is achieved by the following technical solutions: a connecting structure of a square steel pipe and a round steel pipe comprises the square steel pipe and the round steel pipe, wherein the square steel pipe and the round steel pipe are connected through end plates, the connecting end of the square steel pipe is enlarged through a lining plate to form a rectangular end face, and the length of the side of the short edge of the rectangular end face is equal to the diameter of the round steel pipe; the connecting end of the square steel pipe and the connecting end of the round steel pipe are welded on two sides of the end plate respectively through full penetration, and equal-strength connection conversion of the square steel pipe and the round steel pipe is achieved.
The round steel tube connecting end is provided with a cut, and the cross batten plate is inserted into the cut of the round steel tube and is connected through fusion welding.
One end of the lining plate is connected with the end plate, and the other end of the lining plate is connected with the sealing plate in a welding mode.
The utility model discloses do not need the transition of oblique cross-section variable diameter, the connected node edges and corners are clear, and the node is dull and stereotyped, makes things convenient for various component side directions to connect.

Detailed Description
The invention is further illustrated by the following specific examples. Wherein the showings are for the purpose of illustration only and not for the purpose of limiting the same, the same is shown by way of illustration only and not in the form of limitation; for a better explanation of the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
Referring to fig. 1-6, the utility model discloses a square steel pipe 1, circular steel tube 2, end plate 3, welt 4, seal board 5 and cross lacing plate 6, through welt 4 local increase square steel pipe 1, will cross lacing plate 6 inserts circular steel tube 2, then with local square steel pipe 1 after increaseing with have cross lacing plate 6 circular steel tube 2 respectively melt through the welding and be in end plate 3 both sides, realize square steel pipe 1 with circular steel tube 2 equal strength connect the conversion.
Example (b):
as shown in fig. 1, the embodiment of the connection structure of the square steel tube and the round steel tube of the present invention includes:
(1) welding the lining plate 4 on the side surface of the square steel pipe 1 to ensure that the outer section of the square steel pipe 1 is a specific rectangle; the specific rectangle is that the length of the short side of the specific rectangle is equal to the diameter of the round steel pipe;
(2) the circular steel tube 2 is provided with a cut, and the cross batten plate 6 is inserted into the cut of the circular steel tube 2 and then welded; the length of the lining plate 4 is equal to that of the cross batten plate 6, and the lining plate and the cross batten plate are both 500 mm.
(3) Two surfaces of the end plate 3 are polished to be smooth and flat;
(4) the locally enlarged square steel tube 1 and the round steel tube 2 with the cross batten plate 6 are respectively welded on two sides of the end plate 3 in a full penetration mode;
(5) the other end of the locally enlarged square steel tube 1 connected with the end plate is welded with the sealing plate 5.
In order to ensure equal strength connection, all welding in the above technical solutions all adopt one-level groove full penetration weld, and the examples are only for clearly explaining the salient features of the present invention, but not for limiting the embodiments of the present invention. It will be apparent to those skilled in the art that various other modifications and variations can be made in the above teachings without departing from the scope of the invention.
