Description

Connecting structure for reinforcing steel pipe joints by utilizing channel steel
Technical Field
The utility model relates to a building steel structure, building engineering field specifically are an utilize channel-section steel to strengthen connection structure of steel pipe node.
Background
The structural member formed by the steel pipe has the advantages of excellent tensile, compression, bending and torsion resistance, lighter structural weight and steel saving, and the steel pipe structure is widely applied to structural forms of plane or space trusses, net racks, net shells and frames in recent years. For hollow and thin-walled steel pipes, the radial rigidity is far smaller than the axial rigidity, and the radial bearing capacity at the node is far smaller than the axial bearing capacity. The failure mode of the component is mostly shown as node buckling or weld cracking at the joint of the main pipe and the branch pipe, which leads to the failure of the whole structure. Therefore, in order to ensure the basic criteria of 'strong node and weak rod' of the steel structure, a novel steel pipe connecting structure which is convenient to construct, reasonable in structure and capable of improving node ductility is researched and developed.
Therefore, the connection structure for reinforcing the steel pipe joint by using the channel steel is provided by the technical personnel in the field, so as to solve the problems in the background.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an utilize channel-section steel to strengthen connection structure of steel pipe node to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an utilize channel-section steel to strengthen connection structure of steel pipe node, includes the channel-section steel, the channel-section steel is fixed at its top along circular owner's steel-pipe axis direction, and the branch pipe is fixed in on the channel-section steel.
As a further aspect of the present invention: the channel steel is connected with the round main steel pipe and the branch pipe in a welding mode.
As a further aspect of the present invention: the branch pipes are vertically welded in the middle of the top surface of the channel steel.
As a further aspect of the present invention: the steel pipe is characterized by further comprising end plates welded at two ends of the channel steel, the end plates are connected with the round main steel pipes in a welded mode, and the connecting positions of the end plates and the round main steel pipes are arc-shaped and matched with the round main steel pipes.
As a further aspect of the present invention: the cross section of the branch pipe is rectangular, circular or I-shaped.
As a further aspect of the present invention: the width of the channel steel is not more than the diameter of the round main steel pipe.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a novel welded connection structure of circular steel pipe and branch pipe, reasonable in design, the analysis and the research of being convenient for can improve node static strength, avoids being responsible for the branch pipe direct welding and produces complicated welding seam intersecting line, and standardized production can be realized to this structural system, is convenient for extensively correspond to actual engineering.

Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
The first embodiment is as follows: referring to fig. 1 to 3, a connection structure for reinforcing a steel pipe joint by using channel steel comprises channel steel 3, wherein the channel steel 3 is welded and fixed on the top of a circular main steel pipe 1 along the axial direction of the circular main steel pipe, and a branch pipe 4 is welded and fixed on the channel steel 3, so that the connection strength of the device is effectively improved compared with the case that the branch pipe 4 is directly welded on the circular main steel pipe 1.
The branch pipe 4 is vertically welded in the middle of the top surface of the channel steel 3.
The cross section of the branch pipe 4 is rectangular, circular or I-shaped.
The width of the channel steel 3 is not more than the diameter of the round main steel pipe 1, and the channel steel can be connected in a connection mode shown in the figure only when the diameter of the channel steel is less than the diameter of the round main steel pipe 1.
The connection form of the branch pipe 5 and the channel steel can be T-shaped, X-shaped or Y-shaped.
Example two: this embodiment is a further improvement of the previous embodiment: this application still can set up the end plate 2 that welds in 3 both ends of channel-section steel, end plate 2 and 1 welded connection of circular main steel pipe, end plate 2 and 1 hookup location of circular main steel pipe be with the anastomotic arc of circular main steel pipe, and the structural strength of device further improves under this embodiment.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
