Abstract
The utility model relates to a steel pipe connecting structure which belongs to the technical field of steel pipe connecting structures. The utility model is characterized in that the end parts of two adjacent steel pipes are respectively connected with connecting pieces; the upper end and the lower end of an internal supporting pipe is respectively connected with the connecting pieces and flanges, and two flanges are in matched connection. The utility model has delicate and reasonable design, is arranged in the outer wall of a steel pipe, has beautiful appearance and smooth connection, can effectively prevent the dirt accumulation and rust of connecting components, increases the service life and the safety performance, has simple production and processing, reduces the producing cost and is suitable for connecting steel pipes with small diameters and steel pipes with big diameters.
Description
Technical field
The utility model belongs to steel pipe linkage structure technical field.
Background technique
Linkage structure between existing steel pipe, as mobile phone signal transmitting tower, single-pipe tower, light-duty bionical tower etc., the linkage structure between its each section steel pipe mainly adopts inside and outside flange to connect and plug-in connection.But existing inner flange only can be used for the connection between large diameter steel pipe, less than adopting inner flange to connect between the steel pipe of climbing in people's energy; Adopt the outward flange linkage structure, the outward flange of protrusion not only diminishes attractive in appearancely, and contamination, corrosion easily influences working life and safety; Plug-in connection, the processing and fabricating required precision is higher, causes easily and scraps, and cost of production is increased greatly.
The model utility content
The utility model is for overcoming problems of the prior art, and design provides a kind of beautiful shape, produces the technological scheme of steel pipe linkage structure simple, easy for installation.
Described steel pipe linkage structure is characterized in that two adjacent steel tube end parts connect respectively link is set that interior stay tube is connected with link, flange respectively at two ends up and down, and two flanges are connected.
Described steel pipe linkage structure is characterized in that being provided with respectively between link and the flange stiffened panel.
Described steel pipe linkage structure, stay tube is welded to connect with link, flange respectively at two ends up and down in it is characterized in that.
Described steel pipe linkage structure is characterized in that two flanges are spirally connected by bolt.
Described steel pipe linkage structure is characterized in that coating crust between the continuous two ends of steel pipe.
Described steel pipe linkage structure is characterized in that stiffened panel and link, interior stay tube, flange are welded to each other.
The utility model structure is ingenious, and rationally linkage structure is arranged within the outer wall of steel pipe, and beautiful shape, connection smoothness prevent that effectively the contamination of connected element from getting rusty, and improved product working life and Safety performance, and production and processing are simple, has reduced cost of production.Be applicable to the connection between minor-diameter steel-tube, also can be used for the connection between large diameter steel pipe.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Embodiment
As shown in the figure, two adjacent steel pipes 1,1a end connect respectively link 2,2a are set, and link 2,2a are the plectane that is equal to or slightly less than steel pipe 1,1a aperture, also annulus, strip or other shape.Link 2,2a outer end can weld together with steel pipe 1,1a inwall or with the outer wall end face, also can be by bolt being set or alternate manner is fixedly connected.Interior stay tube is welded to connect with link 2, flange 6 respectively at two ends about in the of 3, and interior stay tube 3a is welded to connect with flange 6a, link 2a respectively at two ends up and down.Two flanges 6,6a are spirally connected by bolt 5, and also alternate manner is connected.Bolt 5 numbers can be selected as required.Between link 2 and flange 6, link 2a and the flange 6a stiffened panel 4,4a are set respectively.Stiffened panel 4 upper-end surfaces and link 2 welding, inner side end and 3 welding of interior stay tube, lower end surface and inner flange 6 welding.Stiffened panel 4a upper-end surface and inner flange 6a welding, inner side end and interior stay tube 3a welding, lower end surface and link 2a welding. Interior stay tube 3,3a play the connection supporting effect, can be circular pipe, square tubular, also can be solid post or other shape.Stiffened panel 4,4a are trapezoidal plate, also can be square, strip or other shape, play reinforcement effect, evenly distribute, and number be two or more than two, make stressed evenly, meet design requirement.Steel pipe 1 aperture is less than steel pipe 1a aperture, also can equate or bigger than normal, and its outer wall coats crust 7, makes linkage structure smoothness, profile more attractive in appearance.This linkage structure is applicable to the connection between minor-diameter steel-tubes such as mobile phone signal transmitting tower, single-pipe tower, light-duty bionical tower, also can be used for the connection between large diameter steel pipe, and can also be used for interconnecting between other tubing.
